Description

Commercial car door hasp fixed knot constructs

Technical Field

The utility model relates to a commercial vehicle door lock catch mounting plate and a mounting structure thereof, and belongs to the technical field of heavy commercial vehicle bodies.

Background

The mounting panel of current heavy commercial car door hasp adopts the nut board to wrap up to detain on the reinforcing plate mostly, and the rethread reinforcing plate spot welding is at the structural style on the side wall B post, and this kind of mode can satisfy the regulation requirement of door hasp installation, but still can bring the problem in three aspects: 1) The nut plate is buckled on the reinforcing plate, so that the production is complex and the manufacturing cost is high; 2) In order to ensure the strength of the reinforcing plate, the reinforcing plate and the B column are usually required to be in three-side matching spot welding connection, even the fourth surface is required to be glued and reinforced, the requirement on the dimensional accuracy is high, the reinforcing plate is usually smaller, the positioning is difficult, the production cost is high, and the production efficiency is low; 3) The reinforcing plate is usually required to be adjusted according to different vehicle type sections, and cannot be used for realizing generalization.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model provides the novel vehicle door lock catch fixing structure which is simple in structure, high in universalization degree and high in production efficiency.

In order to solve the technical problem, the utility model provides a commercial vehicle door lock catch fixing structure, which comprises a threaded plate and a box body, wherein the threaded plate is vertically symmetrical, and is provided with two threaded holes for installing a door lock catch and a middle round hole for producing and positioning; the box body is vertically symmetrical, the upper end and the lower end of the box body are provided with L-shaped folded edges, the two sides of the box body are provided with turned edges, the L-shaped folded edges and the turned edges form a middle cavity, and the threaded plate is arranged in the cavity and is surrounded by the L-shaped folded edges and the turned edges; the box body is connected with the L-shaped bending edge on the reinforcing plate through two welding spots, the threaded plate is attached to the reinforcing plate, and limiting of the threaded plate is achieved.

The L-shaped bending edge is provided with a round hole for positioning, and the middle cavity area is provided with a special-shaped avoiding hole for installing the bolt.

The thread plate is made of Q420B plates with the thickness of 6 mm.

The beneficial effects are that: the thread plate and the box body are symmetrical in middle, can be shared left and right, saves development cost, and has simple structure, simple production process and low manufacturing cost; the screw plate is movable, can be adjusted according to the position of the assembled parts, has low production process precision requirement, and reduces the process difficulty of lock catch assembly; the box body only needs to realize the limit requirement of the threaded plate through two welding spots, does not need to bear, has low requirements on the welding process, improves the production efficiency and reduces the failure rate.
