Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective equipment, and in particular to a safe fall-prevention mechanical structure. Background Technology
[0002] Safety fall arrest mechanisms, specifically used in construction, sports (such as rock climbing), etc., are also called safety buckles or hooks. They are mainly used to connect the human body to a fixed object (in rock climbing, this fixed object can be a fixed buckle, while in construction, it can be a fixed steel cable. The operator moves along the direction of the fixed steel cable to carry out construction work).
[0003] In existing hooks, after installation, the safety rope connecting the user and the fixed body (fixed steel cable) are located in the hook space. During the user's movement, the safety rope and the fixed body will inevitably rub against each other to a certain extent, which will cause wear and tear on the outer surface of the soft safety rope, thereby increasing the safety risk.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] To address the aforementioned deficiencies, the purpose of this utility model is to provide a safe fall-prevention mechanical structure that can separate the internal space of the hook and shackle using a barrier component, allowing the safety rope and the fixed body to be placed in different spaces, reducing wear on the safety rope and further improving safety.
[0006] To achieve the above objectives, this utility model provides a safety fall prevention mechanical structure, including a buckle body with an opening, a buckle movably connected thereto and used to seal the opening, and a barrier member connected to the buckle body to block the formation of a local space for placing a safety rope.
[0007] According to the safety fall prevention mechanical structure of this utility model, the buckle body and the sealing buckle have a positioning structure for positioning the sealing state of the sealing buckle; the positioning structure includes a thread provided at the connection end of the buckle body and the sealing buckle and a fixing cylinder screwed onto the buckle body and the sealing buckle; in the positioning state, the fixing cylinder places the connection end of the buckle body and the sealing buckle inside it; in the non-positioning state, the fixing cylinder places the connection end of a single buckle body or sealing buckle inside it.
[0008] According to the safety anti-fall mechanical structure of this utility model, the buckle is hinged to the buckle body, and a torsion spring is installed at the hinge to drive the buckle to reset.
[0009] According to the safety anti-fall mechanical structure of this utility model, the barrier is installed on the buckle by a fixed or hinged connection.
[0010] According to the safety anti-fall mechanical structure of this utility model, the barrier and the buckle are installed on the buckle in a composite hinge manner; two sets of torsion springs are installed at the hinge and drive the buckle and the barrier to enter the initial state respectively; in the initial state, the end of the barrier abuts against the buckle body at a predetermined position.
[0011] According to the safety fall prevention mechanical structure of this utility model, the cross-section of the barrier is an arc-shaped structure with the same curvature as the outer edge of the buckle.
[0012] This invention provides a safe fall arrest mechanism, including a buckle body with an opening, a buckle movably connected to it for sealing the opening, and a barrier connecting the buckle or buckle body to create a partial space for placing a safety rope. The partial space created by the barrier separates the safety rope from the fixed body (the safety rope and the fixed body are located within two separate spaces), thus preventing unnecessary wear on both. The buckle is a rod-shaped structure hinged to the buckle body, with a torsion spring installed at the hinge to drive the buckle back to its original position. Under the action of the torsion spring, the initial state of the buckle (the state without external force) is the sealed state. A positioning structure between the buckle body and the buckle positions the buckle in its sealed state. This positioning structure increases the stability of the buckle in the sealed state, preventing it from reopening under external force. This invention uses the barrier to separate the internal space of the hook and loop, placing the safety rope and the fixed body in different spaces, reducing wear on the safety rope and further improving safety.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0018] See Figure 1 and Figure 2This utility model provides a safety fall prevention mechanical structure, which includes a buckle body 1 with an opening, a buckle 2 movably connected to it and used to seal the opening, and a barrier 3 connecting the buckle 2 or the buckle body 1 to block the formation of a local space for placing the safety rope. The local space 5 formed by the barrier 3 separates the safety rope from the fixed body (the safety rope and the fixed body are respectively located in the two spaces formed by the barrier 3), thereby avoiding unnecessary wear and tear on both.
[0019] In this embodiment, the snap fastener 2 is a rod-shaped structure that is hinged to the snap fastener body 1. A torsion spring is installed at the hinge to drive the snap fastener 2 to return to its original position. Under the action of the torsion spring, the initial state of the snap fastener 2 (the state without external force) is the sealed state. The snap fastener body 1 and the snap fastener 2 have a positioning structure to position the snap fastener 2 in the sealed state. The positioning structure increases the stability of the snap fastener 2 in the sealed state. In the positioned state, the snap fastener 2 will not be reopened by external force.
[0020] See Figure 3 The positioning structure includes a thread provided at the connection end of the buckle body 1 and the buckle 2, and a fixing cylinder 4 screwed onto the buckle body 1 and the buckle 2. The fixing cylinder 4 moves along the extension direction of the thread.
[0021] When in the positioning state, the fixing cylinder 4 places the connecting end of the buckle body 1 and the sealing buckle 2 inside it. At this time, the fixing cylinder 4 fixes the connecting end of the buckle body 1 and the sealing buckle 2, and the sealing buckle 2 cannot be opened.
[0022] In the non-positioning state, the fixing cylinder 4 places the connecting end of the single buckle 1 or the seal 2 inside it. Normally, the fixing cylinder 4 is placed at the connecting end of the seal 2. At this time, the connecting end of the buckle 1 or the seal 2 cannot be fixed, and the seal 2 can be opened.
[0023] The barrier 3 is fixedly or hingedly connected to the buckle 2. In this embodiment, the barrier 3 and the buckle 2 are connected to the buckle 2 in a composite hinged manner. By setting the barrier 3 to be movable, the barrier space can be easily removed, which further facilitates the movement of the safety rope.
[0024] Two sets of torsion springs are installed at the hinge, which respectively drive the buckle 2 and the barrier 3 into the initial state;
[0025] In its initial state, the barrier 3 abuts against the predetermined position of the buckle 1 at its end, thereby achieving spatial isolation.
[0026] Preferably, the cross-section of the barrier 3 of this invention is an arc-shaped structure with the same curvature as the outer edge curvature of the seal 2. This design reduces the space occupied by the barrier 3 in its non-working state (as the barrier 3 fits snugly against the seal 2) and relatively increases the movement space of the barrier 3.
[0027] In summary, this utility model provides a safe fall-prevention mechanical structure, including a buckle body with an opening, a buckle movably connected to it for sealing the opening, and a barrier connecting the buckle or buckle body to create a local space for placing a safety rope. The local space created by the barrier separates the safety rope from the fixed body (the safety rope and the fixed body are located within the two spaces created by the barrier), thereby preventing unnecessary wear on both. The buckle is a rod-shaped structure hinged to the buckle body, and a torsion spring is installed at the hinge to drive the buckle back to its original position. Under the action of the torsion spring, the initial state of the buckle (the state without external force) is the sealed state. A positioning structure is provided between the buckle body and the buckle to position the buckle in its sealed state. This positioning structure increases the stability of the buckle entering the sealed state, and in the positioned state, the buckle will not be reopened by external force. This invention can divide the internal space of the hook and loop space by using a barrier, so that the safety rope and the fixing body are placed in different spaces, reducing the wear of the safety rope and further improving safety.
[0028] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
