The waterproof plastic box realizes the connection and matching of the box body and the box cover through the lock catch component, and the operation mode is as follows: firstly, placing the box cover on the box body, hooking the other end of each hook on the convex column, then pressing the hasp downwards, and simultaneously driving the hooks to act until the hasps and the fixing pieces form connection and matching, so as to complete the closing of the waterproof plastic box; otherwise, the hasp is separated from the fixing sheet, and the opening of the waterproof plastic box can be completed. The waterproof plastic box is convenient to open and close, the box cover can be stably connected to the box body, the sealing performance of a product is improved, and the normal work of electrical elements in the waterproof plastic box is guaranteed.

The utility model discloses further set up to the one end of stationary blade and fix the middle part at the lock body, the other end of stationary blade turns over in succession and turns over a formation barb, the one end of hasp articulates in the upper end of lock body, and the middle part of hasp forms the dead slot, the hasp forms with the stationary blade through the joint cooperation of dead slot and barb and is connected.

The structure can firmly fix the hasp on the fixing sheet, thereby preventing the abnormal opening of the hasp component in a closed state and improving the use reliability of a product.

The utility model is further arranged in the middle of the hook, one section of circular groove matched with the hook is formed on the lock body.

The lock body structure is used for avoiding the hook, so that the normal closing of the lock catch component can be ensured.

The utility model discloses further set up to the transversal "worker" type of personally submitting of mounting groove, the outside arch in both sides of lock body forms the reference column, the lock body passes through the reference column to be connected in the mounting groove of transversal "worker" type of personally submitting, form the flange on the mounting groove, form the pothook with the flange adaptation on the lock body, the pothook is connected on the flange.

Above-mentioned structure makes the lock body can conveniently fix in the mounting groove, and both connect stably, need not other accessories and additionally fix, convenient assembling.

The utility model is further arranged in that the other end of the hasp is folded outwards to form a shifting piece.

The utility model is further provided with the fixing sheet as an elastic piece.

The structure of the poking sheet and the fixing sheet with elasticity are easy for operators to open the waterproof plastic box.
