Technical Field

[0001] This utility model relates to the field of fall protection safety belts, and in particular to a safety belt with emergency functions. Background Technology

[0002] A fall arrestor harness (or simply safety harness) is a personal protective device that restricts movement by establishing a safe connection between the person and a fixed point, preventing falls or mitigating impact during a fall. Falls are among the most common and dangerous accidents in environments such as working at heights, climbing, rooftops, bridges, wind farms, and construction sites. Safety harnesses disperse fall energy, reduce fall height and impact force, thereby improving personal safety and helping to comply with relevant regulations and standards.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: In the event of an emergency need for tools during work, workers usually need to carry a toolbox. However, in actual use, after opening the toolbox, it is necessary to search for and take out the tools one by one, which takes a long time. Moreover, the toolbox is usually large in size, making it inflexible to carry and move, especially in confined work spaces.

[0004] Therefore, those skilled in the art have provided a seat belt with emergency functions to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety belt with an emergency function. After pressing the movable post in the hole above the limiting ring, the push block moves down, pushing the pressure block and the movable box out of the safety belt fixing box, thereby enabling quick access to tools.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A safety belt with emergency function includes a safety belt fixing box and a movable column. First straps are fixedly installed on both sides of the front of the safety belt fixing box. Second straps are hinged to both sides of the upper front of the safety belt fixing box. Two spring telescopic rods are fixedly installed at the lower position of one side of the inner end of the safety belt fixing box. A pressure block is fixedly installed on the other side of the two spring telescopic rods. A movable box is fixedly installed on the other side of the pressure block. Multiple first springs are installed inside the movable box. Movable plates are fixedly installed on the upper ends of the multiple first springs. A limit block is fixedly installed on one side of the upper end of the movable plate. Multiple partitions are fixedly installed on the other side of the upper end of the movable plate.

[0008] A fixing plate is fixedly installed on the upper part of one side of the inner end of the seat belt fixing box. An installation plate is fixedly sleeved on the upper part of the outer side of the movable column. A second spring is fixedly installed at the lower end of the installation plate. A push block is fixedly installed at the lower end of the movable column.

[0009] Furthermore, the two No. 1 straps and the four No. 2 straps are connected in pairs by Velcro, and the movable box is movably set at the outer end of the seat belt fixing box.

[0010] Furthermore, the four No. 2 straps are arranged in pairs, and the two pairs of No. 2 straps are respectively movably arranged on the upper and lower sides of the two No. 1 straps.

[0011] Furthermore, the movable plate is movably disposed inside the movable box, and multiple strong magnets are fixedly disposed inside the movable plate.

[0012] Furthermore, the upper end of the limiting block is sloped on one side, and a limiting ring is fixedly provided on the upper end of the seat belt fixing box.

[0013] Furthermore, the movable column is movably disposed inside the limiting ring, and the push block contacts the top of the pressure block.

[0014] Furthermore, the second spring is connected to the fixing plate at its lower part.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a safety belt with an emergency function. When tools are needed urgently, pressing the movable column inside the hole above the limiting ring moves the push block downwards, causing the pressure block and movable box to move outside the safety belt fixing box, enabling quick tool retrieval and improving on-site handling speed. After stopping pressing the movable column, the ramp-like structure above the limiting block guides the movable plate back to its original position, and the spring telescopic rod pushes the movable box back into the safety belt fixing box. The mounting plate also resets, ensuring the device returns to its initial state and reducing the risk of misoperation. Attached Figure Description

[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] Reference Figures 1-5 One embodiment provided by this utility model:

[0026] A safety belt with emergency function includes a safety belt fixing box 1 and a movable post 14. First straps 2 are fixedly installed on both sides of the front of the safety belt fixing box 1. Second straps 3 are hinged to both sides of the upper front of the safety belt fixing box 1. Two spring telescopic rods 4 are fixedly installed at the lower position of one side of the inner end of the safety belt fixing box 1. A pressure block 5 is fixedly installed on the other side of the two spring telescopic rods 4. A movable box 6 is fixedly installed on the other side of the pressure block 5. Multiple first springs 7 are installed inside the movable box 6. A movable plate 8 is fixedly installed on the upper end of the multiple first springs 7. A limit block 9 is fixedly installed on one side of the upper end of the movable plate 8. Multiple partitions 10 are fixedly installed on the other side of the upper end of the movable plate 8. A fixed plate 11 is fixedly installed at the upper position of one side of the inner end of the safety belt fixing box 1. The movable post 14... 4. An installation plate 13 is fixedly fitted on the upper part of the outer side. A second spring 12 is fixedly installed at the lower end of the installation plate 13. A push block 15 is fixedly installed at the lower end of the movable column 14. The two first straps 2 and the four second straps 3 are connected in pairs by Velcro. The movable box 6 is movably installed at the outer end of the seat belt fixing box 1. The four second straps 3 are in pairs. The two pairs of second straps 3 are movably installed on the upper and lower sides of the two first straps 2 respectively. The movable plate 8 is movably installed at the inner end of the movable box 6. Multiple strong magnets are fixedly installed at the inner end of the movable plate 8. The upper side of the limiting block 9 is sloping. A limiting ring is fixedly installed on the upper side of the seat belt fixing box 1. The movable column 14 is movably installed inside the limiting ring. The push block 15 contacts the upper part of the pressure block 5. The lower part of the second spring 12 is connected to the fixed plate 11.

[0027] Specifically, the No. 1 strap 2 on both sides of the safety belt fixing box 1 is used to pass over the waist of the staff and then be fastened with Velcro. The two No. 2 straps 3 at the top are used to pass over the shoulders and be fixed by buckles. The two No. 2 straps 3 at the bottom pass over the back of the staff and then form an X shape with the two No. 2 straps 3 at the top and are fastened with Velcro.

[0028] When staff need to use tools urgently, they press the movable column 14 in the hole above the limit ring, and the push block 15 moves downward. Since the area below the push block 15 and the area above the pressure block 5 are both sloped, the push block 15 can push the pressure block 5 to move towards the movable box 6, so that the movable box 6 is moved out of the safety belt fixing box 1. After the part with the slot on the movable box 6 is completely moved out of the safety belt fixing box 1, the first spring 7 can push the movable plate 8 to rise, and the staff can quickly take out the tools from the movable box 6.

[0029] After the tool is used, it is placed back between the partitions 10 of the movable plate 8. Since there are multiple strong magnets at the inner end of the movable plate 8, the strong magnets can firmly fix the tool in the movable box 6. After releasing the pressing of the movable column 14, the sloping structure on one side above the limit block 9 causes the movable plate 8 to return to the movable box 6. The spring telescopic rod 4 drives the movable box 6 back into the safety belt fixing box 1, and the second spring 12 below the mounting plate 13 can drive the mounting plate 13 to reset, and the movable column 14 will also reset accordingly.

[0030] It should be noted that when removing the tool, the movable column 14 should be pressed down continuously to prevent the spring telescopic rod 4 from resetting the movable box 6; both the first strap 2 and the second strap 3 are elastic straps, which can adapt to the body shape of different workers.

[0031] Working principle: When a worker needs to use a tool urgently, pressing the movable column 14 in the hole above the limiting ring causes the push block 15 to move downwards. Since both the area below the push block 15 and the area above the pressure block 5 are sloped, the push block 15 can push the pressure block 5 towards the movable box 6, causing the movable box 6 to move out of the safety belt fixing box 1. Once the slotted portion of the movable box 6 is completely removed from the safety belt fixing box 1, the first spring 7 can push the movable plate 8 upwards, allowing the worker to quickly remove the tool from the movable box 6. After using the tool, releasing the movable column 14 causes the sloped structure on one side above the limiting block 9 to return the movable plate 8 back into the movable box 6. The spring telescopic rod 4 then moves the movable box 6 back into the safety belt fixing box 1, while the second spring 12 below the mounting plate 13 can reset the mounting plate 13, and the movable column 14 will also reset, thus restoring the device to its original state.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
