Description

Technical Field

[0001] This utility model belongs to the field of detachment hook technology, specifically relating to an insulated, anti-fall safety detachment hook. Background Technology

[0002] The insulated anti-fall-off safety hook is a device specifically designed for the safety of power lines. It cleverly integrates insulation properties with anti-fall-off functionality, playing a crucial role in the operation and maintenance of power systems. Made of high-quality insulating materials, this hook effectively isolates current, ensuring the personal safety of operators when in contact with equipment and preventing electric shock accidents.

[0003] In current electrical equipment installation and maintenance practices, safety release hooks are crucial components for ensuring the safe and stable operation of electrical equipment. Currently used safety release hooks are installed primarily by using a clamping plate to tightly grip the rod-shaped part of the electrical equipment, combined with a hook to prevent detachment. However, this design has significant drawbacks. The arc groove on the clamping plate, specifically designed to fit the rod-shaped part, is fixed in size and cannot be adjusted. This makes it difficult to achieve precise positioning when encountering rods of varying thicknesses. For thinner rods, a large gap may exist between the clamping plate and the rod, resulting in ineffective fixation and a risk of loosening and detachment; while for thicker rods, the size may be incompatible, preventing installation. This limitation significantly restricts the versatility and applicability of safety release hooks, causing considerable inconvenience to electrical equipment installation and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an insulated, anti-drop safety hook to solve the problem that existing hooks have significant limitations as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulated anti-fall safety hook, including a hook, one end of which is hook-shaped, and the other end of which is fixedly provided with a connecting rod; a clamping component is also sleeved on the connecting rod, the clamping component being composed of a connector and a snap-fit ​​component, wherein: the connector is sleeved on the connecting rod, and the connector is elastically connected to the connecting rod; one end of the snap-fit ​​component is combined and connected to the connector, and the inner surface of the other end has an arc-shaped groove, the arc-shaped groove being connected to the rod-shaped body of an external electrical device, and the connector slides on the connecting rod to a designated position, so that the snap-fit ​​component holds the rod-shaped body tightly, and at the same time the hook is sleeved on the insulator of the electrical device, thereby achieving the purpose of preventing detachment;

[0006] A reinforcing member is also provided in the connection area between the connector and the snap-fit ​​member. One end of the reinforcing member slides with the connector and the other end abuts against the snap-fit ​​member. The installation stability of the two can be improved by the reinforcing member.

[0007] Preferably, the connector is a connecting sleeve, with sliding grooves on both sides of one end of the connecting sleeve, and the reinforcing member is a reinforcing sleeve, with a second protrusion fixed on the inner side of one end of the reinforcing sleeve. The second protrusion is slidably inserted into the sliding groove, thereby realizing the sliding connection between the two and ensuring that the reinforcing sleeve will not separate from the connecting sleeve.

[0008] Preferably, the snap-fit ​​component is a snap-fit ​​plate, and a connecting post is fixedly mounted on the end of the snap-fit ​​plate facing the connecting sleeve. The end face of the connecting sleeve has a hole for inserting the connecting post, and a retaining spring is also provided inside the hole. The retaining spring abuts against the end face of the connecting post. A travel groove is formed on the surface of the connecting post, and a protrusion is fixedly mounted on the inner wall of the hole on the end face of the connecting sleeve. The protrusion slides into the travel groove, wherein the travel groove is L-shaped. When connecting the connecting sleeve and the snap-fit ​​plate, the connecting post at the end of the snap-fit ​​plate... When the connecting post is inserted into the hole, the protrusion will be engaged in the travel groove. Continue pushing the connecting post in, and the connecting post will compress the clamping spring and be subjected to the spring's rebound force until the protrusion reaches the corner of the travel groove. Then, rotate the entire clamping plate so that the protrusion is engaged in the innermost end of the travel groove. At this point, the connecting sleeve and the end face of the clamping plate are completely flush, forming the state shown in the figure. Release the pressure applied to the clamping plate, and under the rebound force of the clamping spring, the protrusion will be pressed against the inner wall of the travel groove, thereby achieving installation limit.

[0009] Preferably, the other end of the reinforcing sleeve is provided with an annular groove, and the surface of the annular groove is provided with multiple deformation grooves. An elastic rope is also sleeved inside the annular groove. In use, when the reinforcing sleeve is pushed toward the clamping plate, the elastic rope will contract and force the area of ​​the annular groove to deform, thereby pressing against the clamping plate and increasing the stability of the connection.

[0010] Preferably, the internal longitudinal cross-sectional area of ​​the reinforcing sleeve is equal to the longitudinal cross-sectional area of ​​the card plate.

[0011] Preferably, the width of the second protrusion is equal to the inner width of the groove, and the depth of the second protrusion is equal to the inner depth of the groove.

[0012] Preferably, the connecting rod is hollow inside, and a built-in spring is provided inside the connecting rod. A limiting plate is also provided inside the connecting sleeve. A groove is opened on the surface of the connecting rod for the limiting plate to pass through and slide. The limiting plate abuts against the end of the built-in spring. Therefore, the elastic force of the built-in spring can push the connecting sleeve and the locking plate toward the hook, thereby achieving the purpose of cooperating with the hook to complete the installation with external electrical equipment. Since this structure is existing technology, it will not be described in further detail here.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the existing one-piece clamping plate is replaced with a modular structure. During actual installation, operators can quickly select and assemble the clamping plate components that match the actual diameter of the electrical equipment rod. This allows for quick replacement of clamping plate components for rods of different diameters, achieving precise positioning and installation. Compared to the previous one-piece clamping plate, which was difficult to adapt to rods of different specifications, this improved modular clamping plate can greatly shorten installation time, reduce repeated adjustments caused by clamping plate mismatch, and significantly improve work efficiency.
