Description

Technical Field

[0001] This utility model belongs to the technical field of high-altitude safety devices, specifically relating to a high-altitude operation safety device with locking and anti-disengagement functions. Background Technology

[0002] In the field of high-altitude operations, safety is of paramount importance. Numerous professional high-altitude safety devices have emerged to provide comprehensive safety protection for workers and equipment. High-altitude operations are also required during the construction of broadcasting networks in complex sites. During high-altitude operations, workers need to wear safety devices to ensure their safety. Hooks and connectors are usually used to fix the safety rope in a certain position.

[0003] However, in existing technologies, hooks are usually designed with an opening, which poses a risk of the hook detaching from the connector, and the safety of workers cannot be fully guaranteed. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a high-altitude work safety device with locking and anti-disengagement functions to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-altitude work safety device with locking and anti-detachment functions includes an annular hook with a notch, the two notched ends of the hook being a first end and a second end, the first end and the second end being located on the same straight line, an anti-detachment sleeve connecting the first end and the second end, the anti-detachment sleeve being slidably connected to the first end and the second end, the anti-detachment sleeve having a circular cross-section, a partition being provided at one end of the anti-detachment sleeve adjacent to the second end, the partition being fixedly connected inside the anti-detachment sleeve, the ratio of the distance from the partition to the two end faces of the anti-detachment sleeve being 1.5-3, a cylindrical cavity being provided between the interior of the anti-detachment sleeve and the end face of the first end, and an elastic element being provided between the interior of the anti-detachment sleeve and the first end.

[0007] Further specifying, the hook includes a first arc-shaped portion and a second arc-shaped portion, a straight portion is connected between the first arc-shaped portion and the second arc-shaped portion, the straight portion is tangent to the connection between the second arc-shaped portion and the second arc-shaped portion, and the notch of the hook is provided in the straight portion.

[0008] Furthermore, the first arc-shaped portion and the second arc-shaped portion have the same radius.

[0009] Furthermore, the radii of the first arc-shaped portion and the second arc-shaped portion are not equal.

[0010] Further, a first locking part is provided on the side of the first end away from the anti-slip sleeve, and a second locking part is provided on the end of the anti-slip sleeve adjacent to the first end, which cooperates with the first locking part.

[0011] Further specifying, when the first locking part is an external thread, the second locking part is an internal thread and is located at the inner end of the anti-disengagement sleeve.

[0012] Further specified, the first locking part is an internally threaded cap, and the second locking part is an externally threaded cap, located on the outside of the anti-disengagement sleeve.

[0013] Furthermore, the cross-sectional dimensions of the annular portion of the first arc-shaped portion and the second arc-shaped portion are less than or equal to the cross-sectional dimensions of the straight portion.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model is ingeniously designed. Through the clever design of the anti-detachment sleeve, when the elastic element is in a naturally extended state, the partition is pressed against the end face of the second end. The hook is a complete ring, and the connector or hanging rope located inside the hook cannot fall out of the hook, effectively preventing the hanging rope and connector from detaching and providing strong safety.

[0016] This utility model, by setting a first locking member and a second locking member, allows the upper end of the anti-detachment member to be fixed to the hook when the anti-detachment member is lifted, without the need to manually maintain a gap between the anti-detachment member and the second end.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains; the terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0026] like Figure 1-4 As shown, a high-altitude work safety device with locking and anti-detachment functions is provided. The two notched ends of the hook 1 are the first end 11 and the second end 12, which are located on the same straight line. An anti-detachment sleeve 2 is connected between the first end 11 and the second end 12. The anti-detachment sleeve 2 is slidably connected to the first end 11 and the second end 12. The cross-section of the anti-detachment sleeve 2 is annular. A partition 21 is provided at one end of the anti-detachment sleeve 2 adjacent to the second end 12. The partition 21 is fixedly connected inside the anti-detachment sleeve 2. The ratio of the distance between the partition 21 and the two end faces of the anti-detachment sleeve 2 is 1.5-3. There is a cylindrical cavity between the interior of the anti-detachment sleeve 2 and the end face of the first end 11. An elastic element 3 is provided between the interior of the anti-detachment sleeve 2 and the first end 11.

[0027] In this embodiment, the anti-detachment sleeve 2 is used to cooperate with the hook 1 to form a complete ring. When both ends of the anti-detachment sleeve 2 simultaneously contact the first end 11 and the second end 12, the hanging rope inside the hook 1 will not detach from the ring hook 1. When the anti-detachment sleeve 2 is slid towards one end of the first end 11, one end of the anti-detachment sleeve 2 adjacent to the second end 12 detaches from the second end 1, allowing the hanging rope to be removed. Simultaneously, the hanging rope can enter the ring hook 1 from this point, and the hook 1 is also locked to the building's connecting parts. Under the action of gravity, the connection position will not contact the notch position, but only the upper or lower end of the notch in the hook 1. The other parts of the hook 1 are integrally formed and have sufficient strength. The inner partition 21 of the anti-detachment sleeve 2 is used to connect the elastic element 3, and simultaneously divides the anti-detachment sleeve 2 into two parts connected to the first end 11 and the second end 12. 3 is used to press the partition 21 of the anti-detachment sleeve 2 against the end face of the second end 12, so that the anti-detachment sleeve 2 will not detach from the second end of the hook 1. When the anti-detachment sleeve 2 is moved upward, it squeezes the elastic member 3, and at the same time, the anti-detachment sleeve 2 detaches from the second end 12, leaving a gap so that the connector can be removed from the hook 1. The ratio of the distance between the partition 21 of the anti-detachment sleeve 2 and the two end faces is 1.5-3, which further limits the position of the partition 21. Under the action of the elastic member 3, one side of the partition 21 is pressed against the end face of the second end 12. The anti-detachment sleeve 2 located at the lower part of the partition 21 is sleeved and connected to the second end 12. The other side of the partition 21 is connected to the spring. At the same time, the upper part of the anti-detachment sleeve 2 is sleeved and connected to the first end 11. The path of movement of the anti-detachment sleeve 2 by squeezing the elastic member 3 can make the lower end of the anti-detachment sleeve 2 detach from the second end 12 and leave a gap. Preferably, the elastic member 3 is a spring.

[0028] Reference Figure 1 and Figure 4 The hook 1 includes a first arc-shaped portion 101 and a second arc-shaped portion 102. A straight portion 103 connects the first arc-shaped portion 101 and the second arc-shaped portion 102. The straight portion 103 is tangent to the connection between the straight portion 103 and the second arc-shaped portion 102. The notch of the hook 1 is located in the straight portion 103. In this embodiment, the first arc-shaped portion 101 and the second arc-shaped portion 102 are used as force points. When the hanging rope contacts the first arc-shaped portion 101 or the second arc-shaped portion 102, the straight portion 103 is subjected to a vertical pulling force, and the anti-slip sleeve 2 connected to the hook 1 is not easily affected.

[0029] Reference Figure 1 and Figure 4 The first arc-shaped portion 101 and the second arc-shaped portion 102 have the same radius. In this embodiment, when the first arc-shaped portion 101 and the second arc-shaped portion 102 have the same radius, the hook 1 is a straight groove shape.

[0030] Reference Figure 2The radii of the first arc-shaped portion 101 and the second arc-shaped portion 102 are not equal. In this embodiment, the dimensions of the first arc-shaped portion 101 and the second arc-shaped portion 102 are further defined. When the dimensions of the first arc-shaped portion 101 and the second arc-shaped portion 102 are not equal, one end of the hook 1 is larger than the other, which is suitable for high-altitude operations in different scenarios.

[0031] Reference Figure 1 A first locking part 41 is provided on the side of the first end 11 away from the anti-slip sleeve 2, and a second locking part 42 is provided on the end of the anti-slip sleeve 2 adjacent to the first end 11, which cooperates with the first locking part 41. In this embodiment, when the first locking part 41 and the second locking part 42 are connected to each other, the lower end of the anti-slip sleeve 2 is separated from the second end 12, leaving a gap. Therefore, the worker does not need to constantly overcome the elastic force of the elastic element 3 to pull the anti-slip sleeve 2 upward, thus leaving a gap to remove the connector or hanging rope, freeing up some of the worker's labor. The first locking part 41 and the second locking part 42 are both located in the upper part. The first locking part 41 and the second locking part 42 will only be connected to each other after the anti-slip sleeve 2 moves to the upper part. The anti-slip sleeve 2 will not be affected by the first locking part 41 and the second locking part 42 during the initial upward movement.

[0032] Reference Figure 2 When the first locking part 41 is an external thread, the second locking part 42 is an internal thread and is located at the inner end of the anti-disengagement sleeve 2. In this embodiment, when the internal thread of the second locking part 42 rotates into the external thread of the first locking part 41, the first locking part 41 and the second locking part 42 are threadedly connected, so that the position of the anti-disengagement sleeve 2 is kept above the second port 12, leaving a notch.

[0033] Reference Figure 1 The first locking part 41 is an internally threaded cap, and the second locking part 42 is an externally threaded cap, located outside the anti-loosening sleeve 2. In this embodiment, when the first locking part 41 is internally threaded, the inner side of the threaded cap is located outside the second locking part 42.

[0034] Reference Figure 1 and Figure 2 The annular cross-sectional dimensions of the first arc-shaped portion 101 and the second arc-shaped portion 102 are less than or equal to the cross-sectional dimensions of the straight portion 103. In this embodiment, when the annular cross-sectional dimension of the first arc-shaped portion 101 or the second arc-shaped portion 102 is less than the cross-sectional dimension of the straight portion 103, a step is provided at the connection, which can restrict the sliding of the connector from the arc-shaped portion to the straight portion 103 to a certain extent.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
