Description

Spring plate type door and window box bolt Technical Field The utility model relates to the field of door and window bolts, in particular to a spring piece type door and window box bolt. Background The bolt is an anti-theft component for preventing doors and windows from being opened from the outside, and also can prevent potential safety hazards caused by the fact that the doors and windows are blown open by wind or accidentally opened by children, so that the bolt is an indispensable component in modern families. The box type bolt of the door and window in the prior art is generally of a spiral spring structure, the spiral spring has a plurality of defects, the service life of the spring is not longer than that of an elastic sheet, and the spring is easy to rust under a high humidity environment to cause elastic attenuation, and meanwhile, the structure is more complicated and difficult to install, so that the box bolt using the elastic sheet to replace the spiral spring is designed. Disclosure of utility model The utility model aims to provide a spring plate type door and window box bolt which solves the problems in the background technology. In order to solve the technical problems, the utility model provides the technical scheme that the elastic sheet type door and window box bolt comprises a box type bolt main body, a bolt switch piece and a pin body, wherein the box type bolt main body is of a shell-shaped structure with an opening at the back, a rectangular opening is formed in the middle section of the front surface of the box type bolt main body, the bolt switch piece is arranged in the rectangular opening and is movably connected with the box type bolt main body through a rotating shaft, a through hole is formed in one end of the box type bolt main body, the pin body can penetrate through the through hole, the cross section shape of the pin body is identical to the shape of the through hole, an elastic sheet is further arranged in the box type bolt main body, the elastic sheet is fixedly connected with the pin body through a pin body link piece, and is movably connected with one end of the bolt switch piece through a transmission structure. As a further description of the above scheme, screw holes are provided in the middle sections of both ends of the box-type latch main body. As further description of the scheme, the pin body link is an iron sheet, the part connected with the pin body is bent upwards, the middle section is provided with a strip-shaped opening, and the width of the strip-shaped opening is larger than the diameter of the screw hole. .
