Description

Technical Field

[0001] This utility model relates to the field of safety rope technology, and more specifically, to a high-strength safety rope. Background Technology

[0002] Safety ropes are made of synthetic fibers and are high-strength and high-toughness ropes. They play a significant role in the rescue and escape of people in high-rise buildings.

[0003] Patent CN213432644U discloses a fire escape rope, including an escape rope body. A bracket is fixedly connected to the outer wall of one end of the escape rope body. A silicone sleeve is fixedly connected to the outer wall of the bracket. A slot is opened at the end of the bracket away from the escape rope body. A slider is provided on the inner wall of the slot away from the silicone sleeve. A rack is fixedly connected to the side of the slider near the silicone sleeve. A central shaft is provided on the side of the rack near the silicone sleeve.

[0004] In the event of an escape, if the main body of the escape rope breaks, it can be replaced by a spare rope or an extension rope to provide support and prevent the user from falling from a height. During use, one end of the escape rope should be hooked to a safe and stable position, and the other end should be wrapped around the waist. Then, use the flexible lasso structure to descend. During use, the main body of the escape rope should be in direct contact with the surface of the rope. People should find gloves or other protective items to protect their hands while falling. However, escape is usually urgent, and people cannot find these protective items quickly. Therefore, during the fall, people's hands are likely to be injured by direct friction with the escape rope.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength safety rope with the advantage of protecting the human hand from direct contact with the safety rope.

[0008] The present invention is further configured such that: a protrusion corresponding to the position of the through groove is fixedly connected to the side of the extrusion plate near the extension block.

[0009] The present invention is further configured such that heat insulation plates are provided on the side of the slider and on the side of the extrusion plate away from the protrusion.

[0010] The present invention is further configured such that the slider has several placement slots.

[0011] The present invention is further configured such that: a plurality of horizontally arranged anti-slip grooves are fixedly connected to the protrusion.

[0012] The present invention is further configured such that: the rope body includes a core layer, a connecting layer and a wear-resistant layer, the core layer is a metal wire, the connecting layer contains a fireproof material, the connecting layer is wrapped around the outside of the metal wire, and the wear-resistant layer is disposed on the outside of the connecting layer.

[0013] In summary, this utility model has the following beneficial effects:

[0014] During the descent, people can press down on the compression plate to push the rope deeper into the groove, thereby increasing the rope's movement path and further increasing the friction between the rope and the slider, slowing down the descent and improving safety.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] A high-strength safety rope, such as Figure 7 As shown, the rope includes a core layer 13, a connecting layer 14, and a wear-resistant layer 15. The core layer 13 is made of metal wire. The connecting layer 14 contains fire-resistant material and is wrapped around the outside of the metal wire. The wear-resistant layer 15 is located on the outside of the connecting layer 14. The metal wire is located at the center of the rope 1 and is made of stainless steel, which has strong corrosion resistance and strength, preventing the rope 1 from breaking. The connecting layer 14, which contains fire-resistant material, can reduce the risk of the rope 1 breaking due to fire during fire escape and improve the strength of the safety rope. The wear-resistant layer 15 is made of nylon and serves to protect the entire rope 1 as the outermost layer.

[0027] like Figures 1-6As shown, a hook 2 is provided at one end of the rope 1, and a slider 3 is slidably connected to the rope 1. Several through slots 4 are provided on the slider 3 for the rope 1 to pass through. One end of the rope 1 is inserted through the through slots 4 in sequence. A groove 5 is provided on the side wall of the slider 3, and a pressing plate 6 is slidably connected to the groove 5. An extension block 7 is fixedly connected to the side of the pressing plate 6 near the through slot 4. The side wall of the extension block 7 abuts against the inner wall of the groove 5. A limit plate 8 is provided at the opening of the groove 5. The slider 3 replaces the person's hand to contact the rope 1. When the safety rope is needed, the hand can be held on the pressing plate 6 and the slider 3. Since the rope 1 passes back and forth through the through slots 4, the friction between the slider 3 and the rope 1 is large, which plays a role in buffering the descent. In addition, during the fall, the person can press the pressing plate 6 to make the pressing plate 6 push the rope 1 to shift deeper into the groove 5, thereby increasing the movement path of the rope 1, further increasing the friction between the rope 1 and the slider 3, slowing down the person's fall speed, and improving safety. By setting a limiting plate 8 at the opening of the groove 5, the extrusion plate 6 will not come out of the groove 5, thus ensuring the stability of the connection between the limiting plate 8 and the slider 3.

[0028] Furthermore, a protrusion 9 corresponding to the position of the through groove 4 is fixedly connected to the side of the extrusion plate 6 near the extension block 7. Several horizontally arranged anti-slip grooves 12 are fixedly connected to the protrusion 9. By setting the protrusion 9, the contact area between the extrusion plate 6 and the rope 1 is increased, thereby improving the anti-slip effect of the rope 1. The anti-slip grooves 12 are horizontally arranged on the protrusion 9, which can further increase the friction between the protrusion 9 and the rope 1, and increase the stability of people during the fall.

[0029] Furthermore, the slider 3 is provided with several placement slots 11, which are designed to fit the shape of a human hand, making it convenient for people to grip during the fall.

[0030] In one embodiment, heat insulation plates 10 are provided on the side of the slider 3 and the side of the extrusion plate 6 away from the protrusion 9. As people fall down the rope 1, the slider 3 and the extrusion plate 6 continuously rub against the rope 1, which can easily cause the surface temperature of the slider 3 and the extrusion plate 6 to rise. The heat insulation plate 10 can reduce the speed of temperature transmission and prevent high temperature from causing damage to the human hand.

[0031] The structural principle of this utility model is as follows:

[0032] When escaping from a height, people do not need to find additional protective gear such as gloves. They only need to tie one end of the hook 2 and rope 1 to a relatively stable building or desk, and the other end to their body. They can hold the pressure plate 6 and the slider 3 with both hands. People can tighten or loosen the pressure plate 6 according to the falling speed, thereby increasing or decreasing the pressure of the pressure plate 6 on the rope 1 to adjust the falling speed. When tightening the pressure plate 6, the protrusion 9 on the pressure plate 6 pushes the rope 1 deeper into the groove 5, increasing the folding distance of the rope 1. The side of the rope 1 is embedded in the anti-slip groove 12, increasing the friction between the rope 1 and the pressure plate 6 and the slider 3, thereby slowing down the falling speed. When it is necessary to increase the falling speed, the pressure plate 6 can be loosened to reduce the pressure of the pressure plate 6 on the rope 1, so that the slider 3 can fall normally. The adjustment method is relatively simple.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
