Technical Field

[0001] This utility model relates to the technical field of automotive seat strap testing devices, and more specifically, to a multifunctional pull test apparatus for automotive seat straps. Background Technology

[0002] Car seat straps are a key component for seat adjustment and safety restraint. They are usually made of high-strength fibers or synthetic materials, combining flexibility and durability. Nowadays, seat straps are integrated with seat belt buckle mechanisms, which can lock quickly in the event of sudden braking or collision. By restricting the body movement of passengers, they reduce the risk of injury and are one of the core components for improving the personal safety of passengers.

[0003] When testing car seat straps, operators often use multi-functional pull test apparatus to test the quality of the car seat straps. However, in actual use, although the existing pull test apparatus has basic testing functions, the clamps are generally fixed inside the device. This makes it very time-consuming and troublesome to replace the clamps if they are damaged. Therefore, it needs to be improved. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional pull test apparatus for car seat straps, including a platform, on which movable hollow boxes are symmetrically arranged, and a driving block is sleeved on the bottom of each of the two hollow boxes. A T-shaped limiting block is fixedly connected to the driving block, and a movable plate located below the platform is slidably sleeved on the T-shaped limiting block.

[0006] A circular block is fixedly connected to the lower surface of the movable plate. A pin is fixedly connected to the movable plate. The pin is slidably inserted into the hollow box and the driving block in sequence. A No. 1 motor is fixedly installed on the lower surface of the driving block. A circular shaft is fixedly sleeved on the output shaft of the No. 1 motor. One end of a driving rod is fixedly sleeved on the circular shaft. A strip-shaped hole is opened along the axial direction of the driving rod. The circular block is slidably connected in the strip-shaped hole.

[0007] As a preferred technical solution of this utility model, the front surfaces of the two hollow boxes are fixedly connected to a fixed clamping block located above the platform, and the front surfaces of the two hollow boxes are movably provided with a movable clamping block located outside the fixed clamping block. The outer surface of the movable clamping block is fixedly connected to a pin, which can be inserted into the fixed clamping block.

[0008] As a preferred embodiment of this utility model, a second motor is fixedly installed in the inner cavity of the two hollow boxes. A rotating shaft is fixedly sleeved on the output shaft of the second motor. One end of the driving rod is fixedly sleeved on the outer surface of the rotating shaft. A driven rod is hinged to the other end of the driving rod. The other end of the driven rod is hinged to the movable clamping block.

[0009] As a preferred technical solution of this utility model, a support plate is fixedly connected to the lower surface of the platform, a drive motor is fixedly installed on the support plate, and a double-threaded screw is fixedly sleeved on the output shaft of the drive motor. The double-threaded screw has two sections of threads in opposite directions, and the outer surface of the double-threaded screw and the inner surface of the drive block are threadedly sleeved together.

[0010] As a preferred embodiment of this utility model, the support plate is further fixedly connected with a first limiting rod arranged parallel to the double-threaded screw, and the outer surface of the first limiting rod and the inner surface of the driving block are slidably sleeved together.

[0011] As a preferred technical solution of this utility model, an L-shaped plate is fixedly connected to the middle of the upper surface of the platform, and a power motor is fixedly installed in the middle of the lower surface of the platform. A single threaded screw is fixedly sleeved on the output shaft of the power motor.

The outer surface of the second limiting rod and the inner surface of the pull ring are slidably sleeved together.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a hollow box, a T-shaped limiting block, a movable plate, a plug, and a driving rod, allows the round shaft and driving rod to start rotating when the No. 1 motor starts running. During this process, the inner surface of the driving rod will drive the movable plate, thereby causing the movable plate and the plug to move backward along the outer surface of the T-shaped limiting block. Eventually, the plug will disengage from the inner surface of the hollow box, at which point the overall fixation of the hollow box will be released, and the operator can directly pull out the entire hollow box for replacement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, this utility model provides a multifunctional pull test apparatus for automotive seat straps, including a platform 1. Two movable hollow boxes 2 are symmetrically arranged on the platform 1. A strip-shaped through hole is formed on the platform 1, and the hollow boxes 2 are slidably connected to the strip-shaped through hole. A driving block 3 is sleeved on the bottom of the inner surface of each of the two hollow boxes 2. A T-shaped limiting block 4 is fixedly connected to the driving block 3. A movable plate 5 located below the platform 1 is slidably sleeved on the outer surface of the T-shaped limiting block 4. A round block 26 is fixedly connected to the lower surface of the movable plate 5. A bolt 6 is fixedly connected to the movable plate 5. The front end of the bolt 6 is inserted sequentially into the hollow box 2 and the driving block 3. A first motor 7 is fixedly installed on the lower surface of the driving block 3. A round shaft 8 is fixedly sleeved on the other end of the output shaft of the first motor 7. One end of a driving rod 9 is fixedly sleeved on the outer surface of the round shaft 8. A strip-shaped hole is formed along the axial direction of the driving rod 9, and the other end of the driving rod 9 is slidably connected within the strip-shaped hole.

[0026] When the operator starts motor 7, the circular shaft 8 and the drive rod 9 will start to rotate. At this time, the rotation of the drive rod 9 will drive the movable plate 5, thereby causing the movable plate 5 to move outward on the T-shaped limit block 4, so that the plug 6 can be inserted into or removed from the hollow box 2 and the drive block 3 to fix or unlock them.

[0027] Each of the two hollow boxes 2 has a fixed clamping block 10 fixedly connected to its front surface above the platform 1. The front surfaces of the two hollow boxes 2 also have movable clamping blocks 11 movably located outside the fixed clamping blocks 10. A strip-shaped through groove is formed on the surface of the hollow box 2, and the rear end of the movable clamping block 11 is slidably connected within the through groove. A pin 12 is fixedly connected to the outer surface of the movable clamping block 11, and the pin 12 can be inserted into the fixed clamping block 10. The movable clamping block 11 and the fixed clamping block 10 can clamp and fix the seat strap, while the pin 12 can penetrate the seat strap and insert into the inner surface of the fixed clamping block 10, thereby increasing the clamping and fixing strength of the seat strap.

[0028] Two motors 13 are fixedly mounted on the rear surfaces of the inner cavities of the two hollow boxes 2. A rotating shaft 14 is fixedly sleeved at the other end of the output shaft of the two motors 13. One end of a drive rod 15 is fixedly sleeved on the outer surface of the rotating shaft 14. A driven rod 16 is hinged to the other end of the drive rod 15. The other end of the driven rod 16 is hinged to the rear end of the movable clamping block 11. When the operator starts the two motors 13, the rotating shaft 14 and the drive rod 15 will start to rotate. At this time, the driven rod 16 will start to rotate under the drive of the drive rod 15.

[0029] A support plate 17 is fixedly connected to the lower surface of the platform 1. A drive motor 18 is fixedly mounted on the support plate 17. A double-threaded screw 19 is fixedly sleeved on the output shaft of the drive motor 18. The double-threaded screw 19 has two sections of threads in opposite directions, and the two sections of threads of the double-threaded screw 19 are respectively sleeved with the inner surface threads of the two driving blocks 3. When the drive motor 18 starts running, the double-threaded screw 19 will start to rotate, thereby causing the two driving blocks 3 to start moving in opposite directions as a whole.

[0030] The support plate 17 is also fixedly connected to a first limiting rod 20, which is parallel to the double-threaded screw 19. The outer surface of the first limiting rod 20 and the inner surface of the driving block 3 are slidably sleeved. The design of the first limiting rod 20 restricts the overall movement direction of the driving block 3.

[0031] An L-shaped plate 21 is fixedly connected to the middle of the upper surface of the platform 1, and a power motor 22 is fixedly installed in the middle of the lower surface of the platform 1. A single-threaded screw 23 is fixedly sleeved on the output shaft of the power motor 22. The single-threaded screw 23 is vertically arranged and its top end is rotatably connected to the L-shaped plate 21. A pull ring 25 is threaded onto the outer surface of the single-threaded screw 23. When the power motor 22 starts running, the single-threaded screw 23 will start to rotate, and at this time, the pull ring 25 will start to move up and down under the drive of the single-threaded screw 23.

[0032] The lower surface of the L-shaped plate 21 is fixedly connected to a second limiting rod 24 parallel to the single-threaded screw 23. The outer surface of the second limiting rod 24 and the inner surface of the pull ring 25 are slidably sleeved. The design of the second limiting rod 24 restricts the movement direction of the pull ring 25.

[0033] Working principle and usage process of this utility model:

[0034] First, the operator places both ends of the seat strap between the fixed clamp 10 and the movable clamp 11, respectively. Then, the operator starts the second motor 13. As the second motor 13 runs, the rotating shaft 14 and the driving rod 15 will start to rotate. The rotation of the driving rod 15 will drive the driven rod 16 and make it rotate. The other end of the driven rod 16 will drive the movable clamp 11, causing the movable clamp 11 to move towards the fixed clamp 10. Finally, the pin 12 will penetrate the seat strap and insert into the inner surface of the fixed clamp 10. The movable clamp 11 and the fixed clamp 10 will then clamp the seat strap, thereby fixing the seat strap.

[0035] Then the operator starts the drive motor 18 and the power motor 22. The operation of the drive motor 18 will cause the double threaded screw 19 to start rotating. At this time, the two drive blocks 3 will start to move in opposite directions along the inner surface of the platform 1. The operation of the power motor 22 will cause the single threaded screw 23 to start rotating. At this time, the pull ring 25 will start to move upward along the outer surface of the second limit rod 24 under the drive of the single threaded screw 23. Finally, under the combined action of the drive blocks 3 and the pull ring 25, the seat strap pulling test is completed.

[0036] When the operator needs to replace the two hollow boxes 2 as a whole, the operator starts motor 7. As motor 7 runs, the round shaft 8 and the driving rod 9 will start to rotate. During the rotation of the driving rod 9, the inner surface of the driving rod 9 will drive the movable plate 5, thereby causing the movable plate 5 and the plug 6 to move backward. Finally, the plug 6 will disengage from the inner surface of the hollow box 2. At this time, the overall fixation of the hollow box 2 will be released, and the operator can directly replace the hollow box 2 as a whole.
