Abstract

The invention discloses a woven belt hook of an automobile safety belt, which has an integral structure formed by directly bending round steel. The woven belt hook comprises a woven belt guiding and limiting ring, an upper metal plate clamping hook and a lower metal plate clamping hook, wherein the woven belt guiding and limiting ring is formed by bending the middle section of thin round steel, and the upper metal plate clamping hook and the lower metal plate clamping hook are formed by symmetrically bending a head section and a tail section of the thin round steel. The limiting ring is track-shaped with an unsealed straight edge, the woven belt passes through the limiting ring, and a sealed straight edge of the limiting ring plays a role in guiding the woven belt; the upper metal plate clamping hook and the lower metal plate clamping hook are formed by extending upward and downward vertical to a limiting ring plane respectively at equidistant positions of an unsealed straight edge and then bending back to the outside of the unsealed straight edge; and the upper metal plate clamping hook and the lower metal plate clamping hook clamp on a car body metal plate. The metal plate clamping hooks are R-shaped, have completely same structures, and are longitudinally symmetrical with each other. The woven belt hook not only can reduce used materials per se and the manufacturing cost, but also has a simple production process, only needs to perform bending, can improve the production efficiency and is simple to mount.

Description

A kind of Woven belt hook of automobile safety belt

Technical field

The present invention relates to the car belt system, be specifically related to the Woven belt hook of safety strap.

Background technology

Current, interior space has become an important indicator weighing the car load traveling comfort.The dwindling of car belt arrangement space often causes ribbon particularly to be interfered with trim panel with other parts in going out band and removal process, causes ribbon to go out the band difficulty, and recovery power is bigger than normal, cassette tape, even the ribbon wearing and tearing, cut situations such as bad.Though lead at present by increase metal Woven belt hook, and then to ribbon, make its mode of avoiding interfering solve above problem with other parts, but there is other defective in existing metal Woven belt hook structure.

As shown in Figure 1, common metal Woven belt hook 1 is to connect a fixed handle 12 by a L shaped hook 11 to constitute, and it utilizes L shaped hook 11 structures and carries out spacing to belt-strap 2 and guiding, fixes by fixed handle 12 screwing holes and vehicle body.

There is following defective in this Woven belt hook structure:

1, complex manufacturing: it adopts the bending of round steel elder generation, and the local rammer in back is flat, carries out punching in the flat position of upsetting again, and complicated technology causes the increase of the low and cost of production efficiency.

2, the fixed form of Woven belt hook 1 relates to two screws, automobile body welding nut and welding process, and this fixed sturcture produces unnecessary fastener cost and welding process cost.

3, Woven belt hook 1 is non-special construction, needs to produce two symmetrical parts part about conduct respectively, easy left and right sides misloading during assembling.

Summary of the invention

The purpose of this invention is to provide a kind of Woven belt hook of automobile safety belt, it not only can reduce self material and manufacturing cost, and production technology is simple, only need bending to get final product, can enhance productivity, and the commonality height, need not distinguish position up and down during assembling, optimize assembly process process.

Technical scheme of the present invention is as follows:

A kind of Woven belt hook of automobile safety belt, it is the integral structure that directly is bent to form by round steel; Described Woven belt hook comprises ribbon guiding and the spacing ring that is bent to form by thin round steel stage casing, and the panel beating up and down that two sections symmetric curvature of thin round steel head and the tail form clamps crotch;

Described spacing ring is the untight runway shape of a straight flange wherein, and ribbon passes wherein, and its osed top straight flange play the guiding role to ribbon; It is not form towards sealing straight flange outside back bending after extend up and down perpendicular to the spacing ring plane respectively the equidistant position of not sealing straight flange that described panel beating up and down clamps crotch again, and described panel beating up and down clamps crotch and is clipped on the vehicle body panel beating.

It is R shape that described panel beating clamps crotch, and shape is identical, up and down symmetry.

This structure laterally clamps the vehicle body panel beating by the clamping of the panel beating up and down crotch at two, during installation, only needing up and down, panel beating clamping crotch inserts rotation a little behind the cooresponding 7 font holes on the vehicle body panel beating, one or two inside corners about making in the panel beating clamping crotch slips over the turning in 7 font holes, hang in the short hole, panel beating clamping crotch is vertically strained about making, and clamps the vehicle body panel beating, and is easy for installation and firm.

The present invention compares with common Woven belt hook and has the following advantages:

1, cancelled upsetting pressure, punching production technology, cancelled fixedly tender such as screw, nut, and cancelled the welding process of bearing's nut, production technology only needs bending, has not only improved production efficiency, has also saved the material cost and the manufacturing cost of part.

2, owing to do not need the round steel punching, the present invention adopts the diameter materials with smaller, has saved material cost.

3, mounting means is beaten the fastening mode of screw by electric rifle or air gun and is changed manual snap fit into, has saved time of setting up.

4, because the particularity of part self structure of the present invention need not be distinguished position up and down during assembling, promptly shared up and down, solved the problem of misloading.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 2, this Woven belt hook is the integral structure that adopts thin round steel directly to be bent to form.Woven belt hook comprises ribbon guiding and the spacing ring 31 that is bent to form by thin round steel stage casing, and the panel beating up and down that is formed by two sections symmetric curvature of thin round steel head and the tail clamps crotch 32.

Ribbon guiding and spacing ring 31 be shaped as the wherein untight runway shape of a straight flange, ribbon 2 passes wherein, its osed top straight flange A play the guiding role to ribbon 2.It is after the midway location that does not seal straight flange B (also can apart from middle equidistant position) is located to extend up and down perpendicular to spacing ring 32 planes respectively that described up and down panel beating clamps crotch 32, form towards straight flange B outside back bending, panel beating clamps crotch folder 32 on vehicle body panel beating 4 up and down again.Panel beating clamping crotch folder 32 is a R shape up and down, and the shape full form together, and is symmetrical up and down.

Referring to Fig. 3, in order to adapt to the installation of this Woven belt hook, on vehicle body panel beating 4, want correspondence to offer mounting hole, mounting hole on the vehicle body panel beating 4 adopts one 7 font hole 41 and a strip hole 42, they distribute up and down, the slotted hole section in 7 font holes 41 and strip hole 42 in-lines, or some distances that staggers, but be parallel to each other.Certainly mounting hole also can adopt the form of each one 7 font hole reversed arrangement up and down.

During installation, earlier ribbon 2 is passed Woven belt hook 3, the panel beating up and down with Woven belt hook 3 clamps 7 font holes 41 and strip hole 42 that crotch 32 is aimed on the vehicle body panel beating 4 again, compresses into the hole, as shown in Figure 4 the position.

The right-hand revolution Woven belt hook 3 then, and the inside corners that makes panel beating on it clamp crotch 32 slips over the turning in 7 font holes 41, hang in the short hole section in 7 font holes 41 on the vehicle body panel beating 4, panel beating clamping crotch 32 is tightened up so up and down, and stepped up vehicle body panel beating 4, finish installation, as shown in Figure 5.
