Description

A kind of improved safety belt lock catch

Technical field

This utility model is related to automobile safety system technical field, is concretely a kind of improved safety belt lock catch.

Background technology

The upper and lower covers occlusion mechanism of existing lock adopts buckle structure mostly at present, as shown in Figure 1.This buckle structure is permissible Effectively prevent the stripping between upper and lower covers, but there is also some shortcomings：Peeling force between upper and lower covers is less than normal, leads to latch in During use, upper and lower covers are peeled off, and cause very big hidden danger to the safety of user.

It is highly important for design a kind of structure simply stripping off the improvement safety belt lock catch that power beats for this.

Content of the invention

This utility model breaches a difficult problem for prior art, devises a kind of structure and simply strips off the improvement seat belt that power is beaten Lock.

In order to achieve the above object, this utility model devises a kind of improved safety belt lock catch, including：Upper lid, lower cover, Lockhole, lock core and pressing post it is characterised in that：The bottom of upper lid offers lockhole, and the top of lower cover is provided with pressing post, presses post Top be connected with lock core, lock core is corresponding with lockhole position, and described lock core is made up of latch hook one and latch hook two, latch hook one with Latch hook two is with regard to pressing the extended line axial symmetry of post centrage.

Described pressing post is cylinder or cuboid.

This utility model compared with prior art, effectively prevent the stripping between upper and lower covers, and interference fit increased lock Interference power between hole and lock core structure, more prevents the disengaging of upper and lower covers, and this utility model structure is relatively simple simultaneously Single, in the middle of the manufacture that can be widely used in safety belt lock catch easy for installation.

Brief description

Fig. 1 is prior art construction schematic diagram.

Fig. 2 is this utility model structural representation.

Fig. 3 is lock core and pressing rod structure schematic diagram in this utility model.

Fig. 4 is the structural representation of this utility model installation.

Referring to Fig. 1 ~ 4,1 is upper lid, and 2 is lower cover, and 3 is lockhole, and 4 is pressing post, and 5 is lock core, and 5-1 is latch hook one, and 5-2 is Latch hook two.

Specific embodiment

In conjunction with accompanying drawing, this utility model is described further.

Referring to Fig. 1 ~ 4, this utility model devises a kind of improved safety belt lock catch, including：Upper lid, lower cover, lockhole, lock Core and pressing post it is characterised in that：The bottom of upper lid 1 offers lockhole 3, and the top of lower cover 2 is provided with pressing post 4, pressing post 4 Top is connected with lock core 5, and lock core 5 is corresponding with lockhole 3 position, and described lock core 5 is made up of latch hook one 5-1 and latch hook two 5-2, Latch hook one 5-1 and latch hook two 5-2 is with regard to pressing the extended line axial symmetry of post 4 centrage.

In this utility model, pressing post 4 is cylinder or cuboid.

After first upper lid 1 and lower cover 2 being engaged well in being embodied as, it is then placed in special fixture, by cylinder Lock core on lower cover 2 surface is pressed in the lockhole of upper lid 1 pressure, then pressing post 4 is pressed into latch hook one and latch hook two Between, prevent lock core from departing from lockhole.
