Problems solved by technology

[0002] At present, the existing locking pins on the market are generally push-pull, and the locking pins are pushed or pushed into a fixed hole. For example, the publication number applied for in China is 103899165A. The patent of tight pin, it is made up of pin plate (1), pin bolt (2), latch hoop (3), pin nose (4), nostril (5), baffle plate (6) and installation hole (7), user The function of locking the doors and windows can be realized only by pushing the pin (2) into the nostril (5), but in this structure, the pin (2) must slide in the latch hoop (3), and the pin There must be a gap between the bolt (2) and the bolt hoop (3), and then there is misalignment when the bolt (2) is inserted into the nostril (5), which is not very convenient for the user to operate, so it has certain limitations In addition, this structure is exposed to the outside for the convenience of user operation, so the security is not very high

Abstract

The invention relates to the technical field of house decoration, in particular to a locking pin. The locking pin comprises a shell, a shifting handle, a connection rod and a leaf spring. A shifting handle groove is formed in the shell. The inner end of the shifting handle is inserted into the shifting handle groove. A first pin hole is formed in the inner end of the shifting handle. The inner end of the shifting handle is rotationally connected with one end of the leaf spring through a first cylindrical pin. The other end of the leaf spring is connected with one end of the connection rod. The connection rod and the leaf spring are located inside the shell. The other end of the connection rod extends out of the shell. A second pin hole is formed in the middle of the shifting handle. A pin groove is formed in the inner surface of the shell. The shifting handle is rotationally connected with the shell through a second cylindrical pin. Two grooves are formed in the positions, on the two sides of the shifting handle groove, of the outer surface of the shell respectively. The outer end of the shifting handle is located inside the grooves. A cover plate is arranged on the back face of the shell and located on the outer sides of the leaf spring and the connection rod. The locking pin is simple in structure, convenient to install and operate, safe and reliable.
