Description

Technical Field

[0001] The utility model relates to the technical field of webbing connection, and particularly relates to a webbing connector structure. Background Art

[0002] A webbing is a narrow fabric made of various yarns and is widely used in products such as luggage and clothing, cargo transportation binding belts, and automobile seat belts. Among them, an automobile seat belt is an important interior part that connects the occupant to the vehicle body in an automobile, directly affecting the comfort and safety of the whole vehicle. Its basic function and main role are: when a vehicle has a collision accident or rolls over, the seat and seat belt assembly firmly restrain the vehicle occupants on the seat to prevent them from flying out of the vehicle or having a secondary collision with the vehicle interior components. The strength of the automobile seat belt fixing point is an important indicator of automobile passive safety and is a mandatory inspection item in vehicle announcement tests. With the emergence of vehicles such as MPVs, there is a design of the upper fixing point of the seat belt on the seat, and the strength verification of such seat belt fixing points is more important. An automobile seat belt fixing point strength test system is an essential device for testing the strength of seat belt fixing points. Generally, a hydraulic or motor-driven actuator is used. The actuator is connected to the human body module through a steel wire rope or a steel chain. The human body module simulates the situation when an occupant wears a seat belt and transmits the load applied by the system to the three fixing points through the seat belt. Under computer control, according to the specified loading force, loading time, and holding time, the actuator drives the human body module to move to achieve the strength test of the seat belt fixing point.

[0003] It can be seen from this that for the strength test of the seat belt fixing point, the strength of the seat belt is not examined, but whether the strength of the fixing point meets the requirements is examined; moreover, the key problem in the test is that the load applied to the human body module needs to be transmitted to multiple seat belt fixing points. In the existing test technology, the following practices are usually adopted: after setting the human body module in the way of simulating an occupant wearing a seat belt, all the redundant seat belts of the vehicle itself are pulled out, directly tied into a dead knot or wound around the hip mold after being pulled out to eliminate the surplus, so that the seat belt is tightly constrained with the human body module to achieve load transmission. The disadvantages of this method are: the pre-test preparation time is relatively long, the winding of the redundant safety webbing is relatively loose, when a force is applied to the channel, the standard value cannot be quickly reached, and due to the loose webbing, it is possible that the equipment stroke reaches the limit value while the set force value does not meet the requirements, etc. Summary of the Utility Model

[0004] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a webbing connector structure to achieve the stable connection of two webbings, which can be used in the strength test of automobile seat belt fixing points, so that the seat belt can be quickly and tightly constrained with the human body module to achieve load transmission.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a webbing connector structure, including two webbings, and also including an upper connector and a lower connector that are overlapped. The middle part of the two connectors is provided with a U-shaped opening. The two webbings are symmetrically arranged on the left and right. A single webbing includes an inner half and an outer half. The inner half passes through the U-shaped openings of the upper connector and the lower connector from top to bottom in sequence, and the outer half bypasses the upper connector outwards and then passes through the U-shaped opening of the lower connector from top to bottom, and after passing through, it is in contact with the passing-out end of the inner half and is in a tightened state.

[0006] In the above scheme: the U-shaped openings on the upper connector and the lower connector are consistent in size and corresponding in position, which is easy to operate and makes the connection between the webbings more stable.

[0007] In the above solution, the width of the webbing is exactly the same as the length of the U-shaped opening, which further prevents the webbing from shaking in the U-shaped opening.

[0008] In the above scheme: the upper connector and the lower connector are metal parts, plastic parts or wooden blocks, and the inner and outer edges of the upper connector and the lower connector are chamfered. The chamfering design of the inner and outer edges prevents burrs from being generated during processing and cutting the webbing during use.

[0009] In the above scheme: the upper connector and the lower connector are both covered with felt to further prevent burrs and flash from cutting the webbing.

[0010] The beneficial effects of the utility model are: due to tension during use, the webbings are squeezed against each other, so that the connection between the two webbings is more stable. The structure acts as a bridge and can be used in the strength test of the safety belt fixed point. Since the safety webbing in the safety belt reel is long, the excess safety belt can be pulled out in advance, cut from the middle to remove the excess webbing, and then the structure is used to achieve the connection, making the test quick and efficient. That is, the structure can quickly and conveniently restrain the human body module, eliminate the excess webbing, and thus transfer the load required by the standard to the fixed point. 2. It has a wide range of applications. For example, this structure can also be used to connect the binding belts for long-distance bus cargo transportation, and the docking of the binding belts is quick and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The above and / or additional aspects and advantages of the present invention will become apparent and easily understood from the description of the embodiments in conjunction with the following drawings, in which:

[0012] Figure 1 It is a schematic diagram of the connector structure.

[0013] Figure 2 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] like Figure 1As shown in FIG. 2, a structure of a webbing connector mainly consists of two webbings 1, an upper connector 2 and a lower connector 3 which are arranged overlappingly.

[0015] Both the middle parts of the two connectors are provided with square openings 4. The two webbings 1 are symmetrically arranged left and right. A single webbing 1 includes an inner half-section a and an outer half-section b. The inner half-section a sequentially passes through the square openings 4 of the upper connector 2 and the lower connector 3 from top to bottom. The outer half-section b bypasses the upper connector 2 outward and then passes through the square opening 4 of the lower connector 3 from top to bottom, and after passing through, it fits (not necessarily fits, it can also be close) with the passing-out end of the inner half-section a and is in a tightened state.

[0016] This structure is ingeniously designed. During use, due to the tension, the webbings 1 are mutually extruded, so that the connection between the two webbings 1 is more stable, and the connector plays a bridging role. It should be noted during use that after the two webbings 1 are threaded, it is best to use the hand or other force-applying tools to apply force to make the upper connector 2, the lower connector 3 and the webbings 1 overlap and tighten mutually.

[0017] Preferably, the sizes of the square openings 4 on the upper connector 2 and the lower connector 3 are the same and the positions correspond to each other, which is convenient for operation and makes the connection between the webbings 1 more stable.

[0018] Preferably, the width of the webbing 1 is exactly the same as the length of the square opening 4, which further avoids the webbing shaking in the square opening 4. The webbing 1 is usually flat.

[0019] Preferably, the upper connector 2 and the lower connector 3 are metal parts, plastic parts or wooden blocks. Chamfers are provided on the inner and outer edges of the upper connector 2 and the lower connector 3. The chamfer design on the inner and outer edges prevents burrs from being generated during the processing of the material and cutting the webbing 1 during use.

[0020] Preferably, both the upper connector 2 and the lower connector 3 are coated with felt to further prevent the burrs and flash from cutting the webbing 1.
