Description

Technical Field

[0001] This utility model relates to the field of climbing hook technology, specifically an insulated climbing hook. Background Technology

[0002] A climbing hook is a connecting component used in high-altitude operations, rock climbing, and fire descent equipment. It primarily serves as a connection between the descender and the operator. Two climbing hooks are connected by an insulated rope to prevent current from being transmitted to the operator during use, thus providing insulation.

[0003] The patent application CN214485539U discloses an easy-to-open climbing hook, comprising a C-shaped hook body and a movable rod. The movable rod is rotatably mounted on the lower end of the hook body, and a positioning component is provided on the upper end of the hook body. A rectangular through groove is formed inside the movable rod, and a connecting block is slidably connected within the rectangular through groove. One end of the connecting block is fixedly connected to a baffle, and the other end of the connecting block passes through the rectangular through groove and is fixedly connected to a limiting plate. The limiting plate is fixedly attached to the inner wall of the upper end of the hook body by the positioning component. A first magnetic strip is fixedly provided on the lower end face of the connecting block, and a second magnetic strip is fixedly provided on the bottom wall of the rectangular through groove. The movable rod of this invention can deflect simultaneously to the inside or outside of the hook body, thereby greatly increasing the opening angle between the movable rod and the hook body, facilitating the removal of the climbing hook from the rope. It has a simple structure and good practicality.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] Carrying hooks are generally used for high-altitude operations. In high-altitude environments, every extra second an operator spends increases the operational risk. Therefore, it is crucial that the carrying hook can be quickly connected to the operator.

[0006] To address this problem, we propose an insulated climbing hook. Utility Model Content

[0007] The purpose of this invention is to provide an insulated climbing hook to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An insulated climbing hook includes a C-shaped hook body, an insulating rope is sleeved on the surface of the C-shaped hook body, an opening and closing mechanism is provided at the low point of the notch of the C-shaped hook body, and a stabilizing mechanism is provided at the high point of the notch of the C-shaped hook body.

[0010] The opening and closing mechanism includes a rotating block fixedly connected to the low point of the notch of the C-shaped hook body. A stop bar is provided on the top of the rotating block, and a rotating groove for cooperating with the rotating block is opened at the bottom of the stop bar. A rotating rod is fixedly connected to the inner wall of the rotating groove. A rotating hole for cooperating with the rotating rod is opened on one side of the rotating block. Torsion springs are fixedly connected to both sides of the rotating block, and one end of the torsion spring is fixedly connected to the inner wall of the rotating groove.

[0011] Preferably, the stabilizing mechanism includes a stabilizing column fixedly connected to the high point of the C-shaped hook notch, an insert block fixedly connected to the top of the stop bar, an insert groove for cooperating with the insert block on one side of the stabilizing column, a limiting sleeve provided on the surface of the stabilizing column, an external thread on the circumferential side of the stabilizing column, and an internal thread for cooperating with the external thread on the top of the inner wall of the limiting sleeve.

[0012] Preferably, the circumferential side of the limiting sleeve is provided with an anti-slip groove, and the interior of the anti-slip groove is provided with anti-slip texture.

[0013] Preferably, a buffer sleeve is fixedly connected to the bottom of the inner wall of the limiting sleeve, and the buffer sleeve is made of rubber.

[0014] Preferably, the embedded block is convex in shape.

[0015] Preferably, the outer surface of the C-shaped hook is provided with an insulating layer, which is formed by spraying insulating paint.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting an opening and closing mechanism, can open the notch of the C-shaped hook by pressing the stop bar near the C-shaped hook body, causing the stop bar to rotate around the rotating rod, and then connecting it to the safety rope on the operator's body. After releasing the stop bar, the torque generated by the torsion spring will cause the stop bar to rotate around the rotating rod, so that the stop bar returns to its original position, thereby achieving the function of quick connection.

[0018] 2. By setting up a stabilizing mechanism, this utility model can drive the stop bar to rotate and reset around the rotating rod while the torsion spring drives it to enter the embedding groove. Then, by rotating the limiting sleeve with a finger, the limiting sleeve will gradually move downward through the cooperation between the internal and external threads, completely covering the embedding block and the stabilizing post. Under the restriction of the limiting sleeve, the embedding block and the stop bar can only be located at the notch, which effectively improves the stability of the climbing hook after connection.

[0027] 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.

[0028] Please see Figure 1 - Figure 7 This utility model provides a technical solution:

[0029] Example 1:

[0030] An insulated climbing hook includes a C-shaped hook body 1, an insulating rope 17 is sleeved on the surface of the C-shaped hook body 1, an opening and closing mechanism is provided at the low point of the notch of the C-shaped hook body 1, and a stabilizing mechanism is provided at the high point of the notch of the C-shaped hook body 1.

[0031] The opening and closing mechanism includes a rotating block 2 fixedly connected to the low point of the notch of the C-shaped hook body 1. A stop bar 3 is provided on the top of the rotating block 2. A rotating groove 4 that cooperates with the rotating block 2 is provided at the bottom of the stop bar 3. A rotating rod 5 is fixedly connected to the inner wall of the rotating groove 4. A rotating hole 6 that cooperates with the rotating rod 5 is provided on one side of the rotating block 2. Torsion springs 7 are fixedly connected to both sides of the rotating block 2. One end of the torsion spring 7 is fixedly connected to the inner wall of the rotating groove 4.

[0032] In this embodiment, considering that climbing hooks are generally used for high-altitude operations, every extra second the operator spends at height increases the operational risk. Therefore, it is crucial that the climbing hook can quickly connect to the operator. By setting up an opening and closing mechanism, pressing the stop lever 3 near the C-shaped hook body 1 causes the stop lever 3 to rotate around the rotating rod 5. Figure 2 As shown, after opening the notch of the C-shaped hook 1 and connecting it to the safety rope on the operator's body, the stop bar 3 is released. The torque generated by the torsion spring 7 will cause the stop bar 3 to rotate around the rotating rod 5, so that the stop bar 3 returns to its original position, thereby achieving the function of quick connection.

[0033] An insulating layer is provided on the outer surface of the C-shaped hook 1, which is formed by spraying insulating paint.

[0034] In this embodiment, by setting an insulating layer, the C-shaped hook 1 can have an insulating function, thereby preventing the C-shaped hook 1 from conducting current and improving safety.

[0035] Example 2:

[0036] Based on Embodiment 1, this embodiment considers that the opening and closing mechanism can facilitate quick connection between the climbing hook and the operator, saving operation time. However, it neglects the stability of the connection. If the torsion spring 7 is damaged, it cannot be guaranteed that the stop bar 3 is in the notch. In this application, the stabilizing mechanism includes a stabilizing column 8 fixedly connected to the high point of the notch of the C-shaped hook body 1. An insert block 9 is fixedly connected to the top of the stop bar 3. An insert groove 10 that cooperates with the insert block 9 is opened on one side of the stabilizing column 8. A limit sleeve 11 is provided on the surface of the stabilizing column 8. An external thread 12 is opened on the circumferential side of the stabilizing column 8. An internal thread 13 that cooperates with the external thread 12 is opened on the top of the inner wall of the limit sleeve 11.

[0037] In this embodiment, the opening and closing mechanism facilitates quick connection between the climbing hook and the operator, saving operation time. However, the stability of the connection is overlooked. If the torsion spring 7 is damaged, the stop bar 3 cannot be guaranteed to be in the notch. Therefore, by setting a stabilizing mechanism, while the torsion spring 7 drives the stop bar 3 to rotate and reset around the rotating rod 5, it will also drive the inserting rod into the inserting groove 10. Then, when the finger rotates the limiting sleeve 11, the limiting sleeve 11 will gradually move downward through the cooperation between the internal thread 13 and the external thread 12. Figure 1 As shown, the embedded block 9 and the stabilizing post 8 are completely enclosed. Under the restriction of the limiting sleeve 11, the embedded block 9 and the stop bar 3 can only be located at the notch, which effectively improves the stability of the climbing hook after connection.

[0038] The circumferential side of the limiting sleeve 11 is provided with an anti-slip groove 14, and the inside of the anti-slip groove 14 is provided with anti-slip texture 15.

[0039] In this embodiment, by setting anti-slip grooves 14 and anti-slip textures 15, it is easy for users to twist the limiting sleeve 11 and control the movement of the limiting sleeve 11, which plays a driving role.

[0040] A buffer sleeve 16 is fixedly connected to the bottom of the inner wall of the limiting sleeve 11. The buffer sleeve 16 is made of rubber.

[0041] In this embodiment, by setting a buffer sleeve 16, the stop rod 3 can be shock-absorbing and buffered when the C-shaped hook body 1 is impacted, so as to prevent the stop rod 3 from hitting the inner wall of the buffer sleeve 16 and causing wear on the internal thread 13.

[0042] Embedded block 9 is in the shape of a convex character.

[0043] In this embodiment, by setting the embedded block 9 to a convex shape, the embedded block 9 can be fully inserted into the embedded groove 10, thereby preventing the stop bar 3 from being unable to sway left and right. After being restricted by the limiting sleeve 11, the position of the embedded block 9 and the stop bar 3 is completely restricted, thus improving the stability of the stop bar 3.

[0044] Working principle: The user presses the stop lever 3 near the C-shaped hook 1, causing the stop lever 3 to rotate around the rotating rod 5. Figure 2 As shown, after opening the notch of the C-shaped hook 1 and connecting it to the safety rope on the operator's body, the stop bar 3 is released. The torque generated by the torsion spring 7 will drive the stop bar 3 to rotate around the rotating rod 5, so that the stop bar 3 returns to its original position, thereby achieving the effect of quick connection.

[0045] As the torsion spring 7 drives the stop lever 3 to rotate and reset around the rotating rod 5, it also drives the inserting rod into the inserting groove 10. Then, by rotating the limiting sleeve 11 with a finger, the limiting sleeve 11 gradually moves downwards through the engagement between the internal thread 13 and the external thread 12. Figure 1 As shown, the embedded block 9 and the stabilizing post 8 are completely enclosed. Under the restriction of the limiting sleeve 11, the embedded block 9 and the stop bar 3 can only be located at the notch, which effectively improves the stability of the climbing hook after connection.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
