The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1 to 4, a small photographic tripod includes a ball joint 1 for connecting a camera, a hemispherical groove seat 2 for rotating and adjusting the direction of the ball joint, and for locking and fixing The screw locking device of the ball joint and the tripod bracket assembly 4 for supporting the ground;

Wherein, a ball head 11 is provided at the bottom of the ball head connector 1, the ball head 11 is set on the hemispherical groove seat 2, and the bottom of the hemispherical groove seat 2 is provided with a wedge-shaped groove, and the screw locking device includes There are adjustment knob 31, wedge block 32, chute base 33 and spherical gland 34, the ball head 11 and hemispherical groove seat 2 are located in the spherical gland 34, and the top of the ball joint 1 penetrates the spherical gland 34 At the top, the bottom of the spherical gland 34 is connected to the chute base 33 , the wedge block 32 is arranged on the chute base 33 and abuts the wedge-shaped slot, and the adjustment knob 31 passes through the side of the spherical gland 34 and is connected to the base 33 . The wedge-shaped block 32 is clamped, and the triangular bracket assembly 4 is connected to the bottom of the chute base 33 .

As shown in FIG. 1 and FIG. 2 , the top of the ball joint 1 can be connected to the camera. Preferably, in order to connect with the interface in the form of a common bolt connection, the top of the ball joint 1 is provided with a connecting bolt 12 . The connection bolt 12 can be connected with the camera end with threaded holes, and the top of the ball joint 1 is connected with the camera by the connection bolt 12, which can improve the scope of application of the present invention. Of course, the top of the ball connector 1 can also be connected to the camera in other connection forms, which is not limited in the present invention.

As shown in FIG. 2 , the ball head 11 at the bottom of the ball head connector 1 can freely rotate on the hemispherical groove seat 2 to adjust the orientation, so as to adjust the direction of connecting the camera. Further, in order to facilitate the user's rotation direction, the connecting bolt 11 is also provided with a hand-tightening nut 13 which is convenient for twisting and adjusting the direction. The user can adjust the direction of the connecting bolt 11 by screwing the nut 13 by hand, which is convenient and practical.

As shown in Figures 1 and 2, after the direction of the ball head 11 is adjusted, the screw locking device can fix the ball head connector 1, so that the camera can be stably maintained in a specific direction. Specifically, when the adjusting knob 31 is rotated clockwise, because the adjusting knob 31 passes through the side of the spherical gland 34 and is engaged with the wedge-shaped block 32, the advancing stroke of the adjusting knob 31 can drive the wedge-shaped block 32 to move forward, and the wedge-shaped block 32 abuts against the wedge-shaped groove. , drive the hemispherical groove seat 2 to move up, so that the ball head 11 is restricted between the hemispherical groove seat 2 and the spherical gland 34 to achieve a firm fixation. At this time, the ball head 11 is firmly locked, and the nut cannot be tightened by hand. 12. Adjust the direction of the ball joint 1, and the locking method is simple and convenient. Further, in order to increase the frictional force of the ball head 11 and prevent the ball head 11 from slipping, the bottom of the ball head 11 is provided with a plurality of laterally arranged thread grooves 111 . The threaded groove 111 can increase the friction force between the surface of the ball head 11 and the hemispherical groove seat 2, so that the ball head is more stable when it is in a locked state.

On the contrary, when the ball head 11 needs to be loosened to adjust the direction, it is only necessary to rotate the adjustment knob 31 counterclockwise to drive the wedge block 32 to move backward, so that the height of the hemispherical groove seat 2 decreases accordingly, and the ball head 11 is no longer dented by the hemisphere. The slot seat 2 and the spherical press cover 34 restrict the locking, and the user can adjust the direction of the ball joint 1 at this time. It should be noted that the adjustment knob 31 is in the form of a threaded connection through the side surface of the spherical gland 34 to engage with the wedge-shaped block 32. The wedge-shaped block 32 has a conical structure with high left and right low, and a wedge-shaped groove corresponding to the wedge-shaped block 32. The chute structure is deep on the left and shallow on the right.

As shown in FIGS. 3 and 4 , the tripod assembly 4 is supported on the ground. Preferably, the tripod assembly 4 includes a hinge seat 41 , screws 42 and three legs 43 . The screws 42 are connected to the chute base 33 through the hinge base 41 from bottom to top, and the three legs 43 are respectively connected to the hinge base 41 . Further, in order to facilitate users to fold and use, the hinge base 41 includes a hinged chassis 411 and an upper cover 412. The upper cover 412 is located above the hinged chassis 411. The top of 43 is provided with a horizontal shaft 431 which is clamped with the hinge port 413 , and the horizontal shaft 431 is arranged on the hinge port 413 . It should be noted that the top of the upper cover 412 and the bottom of the spherical press cover 34 are in contact with each other. In this way, each leg 43 can be turned over within a certain angle range with the horizontal axis 431 as the center. The outriggers 43 can be moved outwards and unfolded, which is simple and convenient; on the contrary, when the outriggers 43 need to be folded, each outrigger 43 is pushed inward, and each outrigger 43 is kept parallel to the ball joint 1, which is convenient for users to fold and place.

As shown in FIG. 1 and FIG. 3 , further, in order to make the tripod assembly 4 fit more closely in the folded state, the width of each leg 43 is gradually narrowed from top to bottom, and two sides of each leg 43 are respectively provided with There is a convex chute 433 . The width of each leg 43 is gradually narrowed from top to bottom, so that when the three legs 43 are in the folded state, the two legs 43 that are close to each other are always in a state of fit; and the design of the convex chute 433, This makes the edges of the legs 43 fit more closely.

As shown in FIG. 1 , further, in order to prevent the outriggers 43 from sliding during support, the bottoms of the outriggers 43 are provided with anti-skid pads 432 . The anti-skid pads 432 can increase the friction between the outriggers 43 and the ground, so that the support effect of the tripod assembly 4 is more stable.

By adopting the above technical solutions, the screw locking device of the present invention can convert the rotary motion of the adjusting knob into the up and down movement of the hemispherical groove seat. When the hemispherical groove seat is upward, the ball head is stably locked in the hemispherical groove. Between the seat and the ball gland, the locking method is firm, and the ball head will not be loosened; when the hemispheric groove seat is downward, the ball head connector is in a loose state, and the user can adjust the direction of the ball head connector. The adjustment method is simple and convenient; the three outriggers are connected to the hinge seat by means of hinges, the outriggers can be folded or unfolded simply and quickly, and they can be folded and tightly fitted; the overall volume is small, the locking is stable, the operation is simple, and the use is convenient.

The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in the present utility model. within the scope of protection.
