Description

Technical Field

[0001] This utility model belongs to the field of seat belt technology, and in particular relates to a seat belt with fall cushioning function. Background Technology

[0002] The main function of a seatbelt is to absorb the impact force during a fall. The cushioning device generally uses elastic materials or special shock-absorbing components, such as cushioning belts, airbags, or spring systems, to reduce the impact force on the body by extending the pause time.

[0003] According to a public disclosure of a fall suspension safety belt with cushioning protection function (publication number: CN 216571287U), it includes a wearable braided belt, a connecting rope on the braided belt, a suspension component on the connecting rope, a protective layer on the braided belt, and the protective layer is connected to the braided belt through a first sewing thread.

[0004] The aforementioned method, which relies on the interplay of components such as braided straps and connecting ropes, is insufficient to effectively mitigate the impact force during a fall. This results in an unstable fall, increasing the risk of injury from the impact, and requires further improvement. Utility Model Content

[0005] The purpose of this invention is to provide a safety belt with a fall-cushioning function. By cooperating with internal components such as telescopic rods and springs, the cushioning effect of the telescopic rods and springs effectively reduces the impact force during a fall. Through the combined action of the telescopic rods and springs, the fall process becomes smoother, thereby reducing injuries caused by impact. This is especially important when working at heights. The cushioning function effectively reduces the physical burden when suspended, particularly when users need to work suspended in the air. By absorbing some of the impact force and pressure, users can work more comfortably, thus solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a safety belt with fall cushioning function, comprising a safety belt body, a connecting block provided on the side of the safety belt body, a cushioning and mitigation component provided at one end of the safety belt body, the cushioning and mitigation component including a buckle, the buckle being provided on the outer wall of the safety belt body, a hook rope provided on the outer wall of the safety belt body, a long rope being fixedly connected to the end of the hook rope away from the safety belt body, a mitigation tube being fixedly connected to the end of the long rope away from the hook rope, a telescopic rod being fixedly connected to the inner wall of the mitigation tube, a round block being fixedly connected to the telescopic end of the telescopic rod, a connecting rope being fixedly connected to the bottom of the round block, a hook being provided at the end of the connecting rope away from the round block, and a spring being provided on the inner wall of the mitigation tube.

[0008] Furthermore, the bottom of the deceleration tube is provided with a slot, which is located on the displacement trajectory of the telescopic rod's telescopic end. The bottom of the safety belt body is provided with an auxiliary strap, the design of which helps to provide the user with additional fixation.

[0009] Furthermore, a sliding rod is fixedly connected to the outer wall of the telescopic end of the telescopic rod. The end of the sliding rod away from the telescopic rod is slidably connected to the outer wall of the buffer tube. The design of the sliding rod is beneficial to assisting the movement of the telescopic end of the telescopic rod and providing additional protection for the telescopic end of the telescopic rod.

[0010] Furthermore, a stop bar is fixedly connected to the outer wall of the deceleration tube. The stop bar is located on the displacement trajectory of the sliding rod. The design of the stop bar helps to prevent the sliding rod from moving too far.

[0011] Furthermore, there are two sliding rods and stop rods, which are symmetrical to each other along the vertical central axis of the deceleration tube. Having two rods helps to make the telescopic rod's extension and retraction ends move evenly.

[0012] Furthermore, a rebound damping component is provided on the inner wall of the damping tube. The rebound damping component includes a short rod, one end of which is fixedly connected to the outer wall of the telescopic end of the telescopic rod. A displacement block is fixedly connected to the end of the short rod away from the telescopic rod. A blocking block is fixedly connected to the inner wall of the damping tube. The displacement block increases the friction when the telescopic rod rebounds, thereby increasing the resistance and reducing the speed of the telescopic rod rebounding.

[0013] Furthermore, the blocking block is located on the displacement trajectory of the displacement block, and several displacement blocks are arranged in a linear array on the inner wall of the deceleration tube. The arrangement of several displacement blocks helps to increase the resistance when the displacement block moves.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes the interaction between internal components such as telescopic rods and springs to achieve a buffering effect that effectively reduces the impact force during a fall. Through the combined action of the telescopic rods and springs, the fall process becomes smoother, thereby reducing injuries caused by impact. This is especially important when working at heights. The buffering function effectively reduces the physical burden when suspended, particularly when users need to work suspended in the air. By absorbing some of the impact force and pressure, users can work more comfortably.

[0016] This invention utilizes the cooperation between components such as the internal blocking block and displacement block of the rebound damping assembly to achieve a spring-back mechanism for the telescopic rod that effectively slows down the rebound speed. This prevents the impact force from directly acting on the user during a fall, avoiding severe impact and potential injury. The friction between the displacement block and the blocking block, through the variation of non-circular and circular surface designs, gradually reduces the rebound speed, minimizing the instantaneous impact of the seat belt on the user. The user will feel more stable after a fall, reducing the risk of injury caused by impact.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, this utility model is a safety belt with a fall buffer function, including a safety belt body 1, a connecting block 2 on the side of the safety belt body 1, a buffering component 3 at one end of the safety belt body 1, the buffering component 3 including a buckle 31, the buckle 31 being disposed on the outer wall of the safety belt body 1, a hook rope 313 being disposed on the outer wall of the safety belt body 1, a long rope 33 being fixedly connected to the end of the hook rope 313 away from the safety belt body 1, a buffer tube 34 being fixedly connected to the end of the long rope 33 away from the hook rope 313, a telescopic rod 35 being fixedly connected to the inner wall of the buffer tube 34, a round block 38 being fixedly connected to the telescopic end of the telescopic rod 35, a connecting rope 39 being fixedly connected to the bottom of the round block 38, a hook 310 being disposed at the end of the connecting rope 39 away from the round block 38, and a spring 36 being disposed on the inner wall of the buffer tube 34.

[0028] The bottom of the deceleration tube 34 is provided with a slot 37, which is located on the displacement trajectory of the telescopic end of the telescopic rod 35. The bottom of the safety belt body 1 is provided with an auxiliary belt 32, which is designed to provide users with additional fixation.

[0029] A sliding rod 311 is fixedly connected to the outer wall of the telescopic end of the telescopic rod 35. The end of the sliding rod 311 away from the telescopic rod 35 is slidably connected to the outer wall of the slowing tube 34. The design of the sliding rod 311 is conducive to assisting the movement of the telescopic end of the telescopic rod 35 and providing additional protection for the telescopic end of the telescopic rod 35.

[0030] A stop bar 312 is fixedly connected to the outer wall of the deceleration tube 34. The stop bar 312 is located on the displacement trajectory of the sliding rod 311. The design of the stop bar 312 helps to prevent the sliding rod 311 from moving too far.

[0031] There are two sliding rods 311 and two stop rods 312, which are symmetrical to each other along the vertical central axis of the deceleration tube 34. Having two rods is beneficial to make the telescopic rod 35 move evenly at the telescopic end.

[0032] A rebound damping component 4 is provided on the inner wall of the damping tube 34. The rebound damping component 4 includes a short rod 41. One end of the short rod 41 is fixedly connected to the outer wall of the telescopic end of the telescopic rod 35. A displacement block 42 is fixedly connected to the end of the short rod 41 away from the telescopic rod 35. A blocking block 43 is fixedly connected to the inner wall of the damping tube 34. The friction of the telescopic rod 35 when it rebounds is increased by the displacement block 42, thereby increasing the resistance and reducing the speed of the telescopic rod 35 when it rebounds.

[0033] The blocking block 43 is located on the displacement trajectory of the displacement block 42. Several displacement blocks 42 are arranged in a linear array on the inner wall of the deceleration tube 34. The arrangement of several displacement blocks 42 helps to increase the resistance when the displacement block 42 moves.

[0034] A specific application of this embodiment is as follows: The safety belt body 1 is connected to the user's waist via the snap-fit ​​of the connecting block 2, forming a loop. The auxiliary belt 32 has buckles 31 at both ends. By fixing the two buckles 31 to the safety belt body 1, the auxiliary belt 32 is connected to the safety belt body 1. The design of the auxiliary belt 32 provides additional fixation for the user, ensuring the safety belt body 1 is securely worn. The hook rope 313 is secured to the outer wall of the safety belt body 1, connecting the long rope 33, the deceleration tube 34, the telescopic rod 35, the spring 36, the round block 38, the connecting rope 39, and the hook 310 to the safety belt body 1. In use, the safety belt body 1 is first worn around the waist, and the auxiliary belt 32 passes horizontally through the user's crotch, supporting this area. Then, the hook 310 can be hooked at a certain point, and the user can then move downwards along the long rope 33 for suspension work, etc., to withstand the impact of a fall. When subjected to impact pressure, the long rope 33 moves downwards and pulls on the telescopic rod 35, causing the telescopic end of the telescopic rod 35 to extend and retract. This causes the sliding rod 311 to slide on the outer wall of the buffer tube 34 and pulls on the spring 36, putting pressure on the telescopic rod 35 and the spring 36. The telescopic rod 35 and the spring 36 absorb the pressure, reducing the impact when the suspension moves downwards and preventing accidental falls. When a user falls, the buffering effect of the telescopic rod 35 and the spring 36 can effectively reduce the impact force during the fall. Through the combined action of the telescopic rod 35 and the spring 36, the fall process can be made more stable, thereby reducing the injury caused by the impact. This is especially important when working at height. The buffering function can effectively reduce the physical burden when suspended, especially when the user needs to work suspended in the air. By absorbing some of the impact force and pressure, the user can work more comfortably and reduce the injury to the waist and back caused by prolonged suspension.

[0035] The telescopic rod 35 described above will extend and retract during a fall. When the telescopic rod 35 is no longer subjected to impact pressure, it will automatically spring back to its original position. When the telescopic rod 35 springs back to its original position, it will cause the short rod 41 and the displacement block 42 to move upwards to reset. The side of the displacement block 42 closest to the blocking block 43 has an arc surface. When the displacement block 42 moves downwards, the arc surface reduces friction, lowering the resistance between it and the blocking block 43. However, when the displacement block 42 moves upwards, it contacts the non-arc surface of the blocking block 43, thus increasing friction and the resistance between the displacement block 42 and the blocking block 43. This slows down the speed at which the telescopic rod 35 springs back when it is not subjected to impact, thus buffering the extension. When the telescopic rod 35 rebounds, it impacts the long rope 33, hook rope 313, and seat belt body 1. The rebound mechanism of the telescopic rod 35 can effectively slow down the rebound speed, so that when falling, the impact force will not directly act on the user, avoiding violent impact and potential injury. The friction between the displacement block 42 and the blocking block 43, through the change of non-circular and circular surface design, makes the rebound speed gradually decrease, reducing the instantaneous impact of the seat belt on the user. This design is equivalent to a gradual deceleration effect. By reducing the severity of the rebound, the user will feel more stable after falling, reducing the risk of injury caused by impact, and also improving the comfort and user experience of the seat belt.
