Detailed Description

The embodiment is given by fig. 1-8, the utility model comprises a lower installation shell 1, an upper installation shell 2 is detachably connected to the top of the lower installation shell 1, one side of the surface of the upper installation shell 2 protrudes out of the other side of the surface, a pressing key 3 is arranged at the joint of the lower installation shell 1 and the upper installation shell 2, the bottom of the lower installation shell 1 is rotationally connected with a fixed base 5, a groove matched with the fixed base 5 is formed in the bottom of the lower installation shell 1, and positioning grooves 6 are formed in the joint edges of the fixed base 5 and the lower installation shell 1.

In this embodiment, the fixing base 5 needs to be fixedly installed at the edge of the door body or the door frame by using glue, and after rotating, extends out of the door body or the door frame to block the door body from being closed; wherein, convex last installation casing 2 is used for hindering the door body, and is bulky, and the buffering effect that obtains is good, goes up installation casing 2 simultaneously and can dismantle through the hidden discount, also can in time change after damaging.

The inside fixed mounting of installation casing 1 has fixed column 31 down, presses the key 3 and cup joints the surface at fixed column 31, presses the key 3 and is located the inside one side fixedly connected with first spring 7 of installation casing 1 down, and the other end of first spring 7 and the inside fixed connection of installation casing 1 down, presses the bottom an organic whole of key 3 and has formed the driving lever, and the inner chamber bottom of installation casing 1 has offered the arc wall 8 that supplies driving lever pivoted down.

In this embodiment, the smooth pressing key 3 can be better retracted into the lower mounting housing 1 when contacting with the door body or the door frame, so as to avoid the pressing key 3 damaging the door body or the door frame, and also avoid the pressing key 3 from being damaged; the pressing key 3 acts after the door is opened, so that the pressing key 3 can push the lower mounting shell 1, and the door body can be blocked to be closed after the lower mounting shell 1 rotates.

The middle part of unable adjustment base 5 is integrated with the fixed connection post, and the one end of fixed connection post is run through the bottom threaded connection of installation casing 1 down has 14, and the surface activity of fixed connection post has cup jointed second spring 13, and the one end of second spring 13 is pegged graft on unable adjustment base 5, and the other end of second spring 13 offsets with the inside of installation casing 1 down.

In this embodiment, the second spring 13 is used to keep the tendency of rotating toward the locked state, but is blocked by the door frame, and automatically rotates to the locked state to prevent the door body from closing when the door is opened again.

The inside of recess is fixed mounting respectively and is had spacing post 12 and first locating part 11, and the inner wall of unable adjustment base 5 is formed with first protruding piece 51 and second protruding piece 52 respectively an organic whole, and unable adjustment base 5's inside still is formed with first fixture block 53 an organic whole.

In this embodiment, the first limiting member 11 and the limiting post 12 are disposed at an angle of 150 ° in the circumferential direction of the groove, and are matched with the first clamping block 53, so that the rotation range of the lower mounting housing 1 on the fixed base 5 is 150 °, and of course, other required angle values can be set as required.

The grooves formed between the first and second boss 51 and 52 are matched with the shift lever.

In this embodiment, the three states of the shift lever on the side of the first protruding block 51, between the first protruding block 51 and the second protruding block 52, and on the side of the second protruding block 52 correspond to a normally open state, a to-be-locked state, and a locked state, respectively;

normally open state: as shown in fig. 10, the door stop is installed at the edge of the installation door plate 100, and the upper end of the door stop is inclined toward the middle of the installation door plate 100, so that people can freely close the door;

and (5) a state to be locked: as shown in fig. 9, the door stop is vertically installed at the edge of the installation door panel 100, and when the door is closed, the push key 3 is pushed into the door stop by the compression of the door frame, and then keeps the tendency to rotate toward the locking state by the action of the second spring 13, but is blocked by the door frame, and automatically rotates to the locking state to prevent the installation door panel 100 from being closed when the door is opened again by the user;

locking state: as shown in fig. 11, the door stop side protrudes from the installation door panel 100, and blocks the installation door panel 100 from closing.
