Detailed Description

The utility model is further described below with reference to the drawings and specific examples, which are not intended to be limiting.

As shown in fig. 1 and 2, there is shown a novel shear pin structure of a preferred embodiment, comprising:

The mounting seat 1, the sleeve 2, the round pin axle 3, the handle 4 and elastic component, a surface mounting of mount pad 1 is on a door body, the one end of sleeve 2 is installed in another surface of mount pad 1, sleeve 2 has a accommodation space 5, accommodation space 5 extends along the length of sleeve 2 and sets up, a through-hole has been seted up on mount pad 1, accommodation space 5 and through-hole intercommunication set up, a groove group has been seted up to the outer wall of sleeve 2, groove group and accommodation space 5 intercommunication set up, round pin axle 3 movable mounting is in accommodation space 5, the one end of round pin axle 3 is operable to pass or deviate from the through-hole, the one end of handle 4 is installed in the outer wall of the other end of round pin axle 3, handle 4 movable mounting is in the groove group, the one end of elastic component is installed in one side inner wall that accommodation space 5 kept away from mount pad 1, the other end rotation of elastic component is installed in the other end of round pin axle 3.

In the practical use process, after each part is installed, when the door body is required to be locked, a user dials the handle 4, so that the handle 4 moves along one end close to the mounting seat 1 in the groove group, and then drives the pin shaft 3 to move until one end of the pin shaft 3 passes through the through hole in the mounting seat 1 and stretches into a lock hole in the door frame, at the moment, the elastic piece is in a compressed state and has a trend of stretching, so that the pin shaft 3 is propped against the lock hole in the door frame, when the door body is required to be opened, the user dials the handle 4, so that the handle 4 moves along one end far away from the mounting seat 1 in the groove group, and further drives the pin shaft 3 to move until one end of the pin shaft 3 is separated from the through hole in the mounting seat 1 and stretches into the accommodating space 5.

Further, as a preferred embodiment, the groove group includes: first spout 6, second spout 7 and third spout 8, first spout 6 extend along the length direction of sleeve 2 and set up, and second spout 7 and third spout 8 all set up along the circumference of sleeve 2, and the one end of second spout 7 communicates with the one end of first spout 6, and the one end of third spout 8 communicates with the other end of first spout 6, and first spout 6, second spout 7 and third spout 8 all set up with accommodation space 5 intercommunication.
