When the cylindrical tops (31, 41) of the connecting shafts (3, 4) are pressed down, the connecting shaft radial protrusions (45) and the rotating member guide protrusions (65) are both downwards along the guide grooves (28). Slide until it is disengaged from the guide groove (28), and the rotating part rotates so that the guide protrusion (65) is supported in the recess (27) of the adjacent zigzag protrusion at the bottom of the positioning mechanism. At this time, the connecting shaft is in the direction of gravity. Slide down, so that the connecting shaft protrudes from the through hole by the first height, at this time, only the cylindrical part (32, 42) of the connecting shaft protrudes from the through hole, and the limiting part (33, 43) of the connecting shaft leaves the connecting part (5), so that the two mounting seats (1, 2) can be rotated relative to the connecting portion (5) without being restricted by the inner surface limiting mechanism of the connecting portion, and finally the fence pieces connected with the mounting seat can form different angles.

As shown in Figure 2, the guide grooves (28) are set to 4, which are arranged at 90 degrees in the circumferential direction of the positioning mechanism; the upper end of the guide groove is connected with the positioning mechanism, and the two sides of the guide groove are respectively adjacent to the bottom of the positioning mechanism The slope of a zigzag-shaped protrusion and the apex angle of another zigzag-shaped protrusion at the bottom of the positioning mechanism are half of the width of the triangular protrusion of the connecting shaft.

The guide protrusions (65) of the rotating part are set to 4, which are radially protruded at a distance of 90 degrees in the circumferential direction of the triangular protrusions (66) of the rotating part; The side radially protrudes and has a vertical surface corresponding to the vertical side of the zigzag protrusion (26) at the bottom of the positioning mechanism and an inclined surface corresponding to the oblique side of the zigzag protrusion (26) at the bottom of the positioning mechanism. That is, the guide protrusion (65) has a vertical surface extending downward from the apex of the triangular protrusion (66) and an inclined surface extending along the hypotenuse of the triangular protrusion (66), and the inclined surface is consistent with the zigzag protrusion ( 26) are opposite to each other; the width of the guide protrusion of the rotating part is slightly smaller than the width of the guide groove, so that it can freely slide up and down in the guide groove.

When the radial protrusions (45) of the connecting shaft and the guide protrusions (66) of the rotating part are both embedded in the guide grooves (28), the cylindrical parts (32, 42) and the restricting parts (33, 43) of the connecting shafts are both embedded in the guide grooves (28). The through hole of the mounting seat is exposed, and the connecting shaft is at the second height (high position) at this time. Press the top end of the cylindrical part of the connecting shaft (3, 4), the connecting shaft pushes the rotating part and slides down, the triangular protrusion (66) of the rotating part is disengaged from the guide groove (28) and is just snapped on the bottom of the positioning mechanism. In the recess (27) formed by the vertical sides of the zigzag protrusions and the inclined surfaces of the adjacent zigzag protrusions; since the rotating part is supported by the zigzag protrusions at the lower end of the positioning mechanism, the elastic force exerted by the elastic member is also supported by the serrations at the lower end of the positioning mechanism. The shaped protrusion is supported without being applied to the connecting shaft, therefore, the connecting shaft falls to a low position under the action of gravity, and at this time, the restricting parts (33, 43) of the connecting shaft (3, 4) do not pass through the through holes (11, 12) Extending, just at the first height (low position), the mounting base can rotate freely relative to the connecting part. When the top end of the cylindrical part of the connecting shaft (3, 4) is pressed down again, the connecting shaft pushes against the rotating part and slides down, and at this time the guide protrusion (65) of the rotating part just rotates to the adjacent guide groove (28) ), the rotating part pushes against the radial protrusion (45) of the connecting shaft and slides up along the guide groove (28), and the connecting shaft is at the second height (high position) at this time; Exposed in the holes, the connecting shaft restricting portions (33, 43) engage with restricting mechanisms on the inner surface of the connecting portion to restrict the rotation of the connecting shaft relative to the connecting portion.

The fence connecting piece of the utility model cleverly designs the dimensions of the radial protrusion at the lower end of the connecting shaft, the guiding protrusion of the rotating part and the guide groove, so that the cylindrical top of the connecting shaft can be pressed down with a finger to realize the automatic rotation of the rotating part, and the first Switch between the first height and the second height at any time. This saves a lot of manpower and also facilitates the installation of the fence connector.

The fence connector of the utility model can firstly install the mounting seat (1, 2), the connecting shaft (3, 4), the rotating part (60, 61) and the elastic part (71, 72) on the side of the fence piece, and the connecting shaft ( 3, 4) Insert the through holes (11, 21) of the mounting seat, and the radial protrusions (45) of the connecting shaft and the guide protrusions (65) of the rotating parts are both located in the guide grooves (28). The installed connecting piece is shown in Figure 3. Under normal conditions, the elastic parts (71, 72) push the rotating parts (60, 61) against the bottom of the connecting shafts (3, 4), and push the cylindrical part of the connecting shafts (32, 42) and part of the restricting parts (33, 43) are exposed through the through hole of the mounting seat and are at the second height. At this time, the restricting part of the connecting shaft interacts with the restricting mechanism of the connecting part to restrict the connection between the connecting shaft and the connecting part. The mutual rotational movement between the two fence pieces (not shown in the figure) limits the relative rotational movement between the two fence pieces.

When the angle between the fence pieces needs to be adjusted, press down the top of the cylindrical part of the connecting shaft to resist the elastic force of the elastic part, the radial protrusion (45) of the connecting shaft and the guiding protrusion (65) of the rotating part guide the slide down in the groove (28); when the guide protrusion (65) of the rotating part reaches the bottom of the guide groove (28), the inclined surface of the guide protrusion (65) guides the inclined surface of the zigzag protrusion (26) at the bottom of the positioning mechanism Rotation occurs down, and the guide protrusion (65) is supported on the concave portion (27) of the adjacent zigzag-shaped protrusion at the bottom of the positioning mechanism; at this time, the rotating part is supported by the zigzag-shaped protrusion concave portion at the lower end of the positioning mechanism to resist the elastic force of the elastic member, and the connection The shaft slides down under the action of gravity, the restricting parts (33, 43) of the connecting shaft retreat into the through holes (11, 21) of the mounting seat, and only the cylindrical part (32, 42) is exposed through the through holes (11, 21); At this time, the connecting shaft is located at the first height, and the connecting shaft and the connecting portion can be rotated relative to each other, so that it is convenient to adjust the two adjacent fence pieces to a desired angle.

After completing the operation of adjusting the angle of the fence piece, press down the top of the cylindrical part (32, 42) of the connecting shaft again to resist the elastic force of the elastic parts (71, 72), and the connecting shaft (3, 4) pushes the rotating part (60, 42) against the elastic force of the elastic parts (71, 72). 61) Move downward; when the connecting shaft pushes the rotating part to move downward, the rotating part will automatically rotate so that the recess of the triangular protrusion (66) of the rotating part matches the vertex of the triangular protrusion (46) at the lower end of the connecting shaft, and this When the inclined surface of the guide protrusion (65) of the rotating part is partially in contact with the inclined surface of the zigzag protrusion (26) at the bottom of the positioning mechanism, under the push of the elastic parts (71, 72) at the lower end of the rotating part, the guide protrusion ( The inclined surface of 65) slides along the inclined surface of the rectangular protrusion (26) at the lower end of the positioning mechanism, and with a "click" sound, the guide protrusion (65) of the rotating part enters the adjacent guide groove (28) again, and the rotating part (60, 61) push the connecting shafts (3, 4) to the second height. At the same time, the restricting part of the connecting shaft interacts with the restricting mechanism of the connecting part to restrict the mutual rotational movement between the connecting shafts (3, 4) and the connecting part (5), thereby restricting the angle formed by the two fence pieces.

In this way, the first height and the second height of the connecting shaft can be switched alternately by pressing the top of the connecting shaft, so that the angle between the fence pieces can be adjusted/fixed conveniently.

The mounting seat, the connecting shaft and the connecting part of the fence connecting piece of the utility model are respectively integrally formed by ABS plastic or PVC plastic.

The fence connecting piece of the utility model can also be made of environmentally friendly resin, which reduces environmental pollution and avoids the adverse health effects of children's gnawing.

The connecting shaft restricting part of the fence connecting piece of the utility model is matched with the positioning mechanism of the through hole of the mounting seat and the limiting mechanism in the cylindrical part of the connecting part, so that the angle of the mounting seat is fixed and the connected fence pieces will not shake randomly. The cylindrical circumference diameter of the upper end of the connecting shaft is smaller than the circumference diameter of the positioning mechanism of the through hole of the mounting seat and the cylindrical body restricting mechanism of the connecting part, so that the connecting part cannot restrict the rotation of the connecting shaft, and the angle of the mounting seat can be adjusted at will. Such a cleverly designed structure can conveniently enclose adjacent fence pieces at different angles.

The fence connecting piece of the utility model has a simple structure, and the fence connecting piece can flexibly adjust the fence pieces to the required angle conveniently and easily, so that the plurality of pieces of fences can form any maintenance shape. Multiple fences can also be folded side by side, and the folded fence does not take up space; when the fence is used again, it is only necessary to adjust the angle of the mounting seat.
