A hook

Abstract

The present application discloses a hook, wherein a connecting hole of the S-shaped hook is movably connected with a hanging ear of a base rod through a connecting shaft, and when the load-bearing bend of the S-shaped hook is hung on a heavy object, the S-shaped hook and the hanging ear of the base rod move relative to each other, so that the locking bend of the S-shaped hook and the cylindrical seal of the base rod are closed and cooperated to form a locked hook. When the base rod is lifted, the load-bearing bend of the S-shaped hook loses the support of the heavy object, and under the action of the deadweight of the S-shaped hook, the S-shaped hook moves downward along the hanging ear of the base rod, and the locking bend of the S-shaped hook is separated from the cylindrical seal of the base rod. Due to the structural characteristics of the S-shaped hook itself, the center of gravity of the S-shaped hook is on the outside, and the hook is flipped outward, the hook opening is opened, and the hook is separated from the heavy object, thereby solving the defect that the hook with the normally closed anti-detachment blocking piece needs to be manually released to detach from the hanging object, and at the same time avoids the technical problem of the risk of safety accidents caused by using an open hook.

They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0036] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present application based on the specific circumstances.

[0037] For easier understanding, see Figures 1 to 4 , an embodiment of a hook provided by the present application includes: an S-shaped hook 1 and a base rod 3;

[0038] The S-shaped hook 1 includes a locking bend 101, a load-bearing bend 102 and a connecting hole 103;

[0039] The center of gravity of the S-shaped hook 1 is located outside the S-shaped hook 1;

[0040] The upper section of the base rod 3 is bent at a preset arc, and a hook positioning groove 302 is provided at the bent portion;

[0041] The end of the upper section is provided with a cylindrical seal 301, which is connected to the locking bend 101;

[0042] The base rod 3 is provided with hanging ears 303 on both sides of the bending part;

[0043] The connecting hole 103 is movably connected to the hanging ear 303 via the connecting shaft 2 .

[0044] It should be noted that if Figure 4 As shown, the positioning groove 302 is communicated with the cylindrical seal 301 , and the positioning groove 302 provides a movable space for the S-shaped hook 1 .

[0045] The hook provided in the embodiment of the present application has a connecting hole 103 of the S-shaped hook 1 movably connected to the hanging ear 303 of the base rod 3 through the connecting shaft 2. When the load-bearing bend 102 of the S-shaped hook 1 is hung on the hanging object, the S-shaped hook 1 and the hanging ear 303 of the base rod 3 move relative to each other, so that the locking bend 101 of the S-shaped hook 1 is closed and matched with the cylindrical sealing opening 301 of the base rod 3 to form a locked hook. When the base rod 3 is lifted, the load-bearing bend 102 of the S-shaped hook 1 loses the support of the hanging object, and the S-shaped hook 1 is lifted under the action of its own weight. When the hook is in use, the S-shaped hook 1 moves downward along the hanging ear 303 of the base rod 3, and the locking bend 101 of the S-shaped hook 1 is separated from the cylindrical seal 301 of the base rod 3. Due to the structural characteristics of the S-shaped hook 1, the center of gravity of the S-shaped hook 1 is on the outside, and the hook flips outward, the hook opening is opened, and the hook is separated from the hanging object, which solves the defect that the hook with the normally closed anti-detachment block plate needs to be manually released to separate from the hanging object, and at the same time avoids the technical problem of the risk of safety accidents caused by using an open hook.

[0046] As a further improvement to the hook of the embodiment of the present application, the curvature of the upper section of the base rod 3 is 45°.

[0047] As a further improvement to the hook of the embodiment of the present application, in order to facilitate the connection and fixation of the hook with other auxiliary tools, an installation hole 304 can be further provided in the lower section of the base rod in the embodiment of the present application, and the installation component can be used to connect with other auxiliary tools through the installation hole 304.

[0048] As a further improvement to the hook of the embodiment of the present application, the opening direction of the hook sometimes needs to be adjusted at the work site. Therefore, the connection between the upper section and the middle section of the base rod can be provided with a rotational positioning connection mode, and a rotational locator 4 is provided in the middle section of the base rod. The upper section of the base rod 3 is connected to the middle section of the base rod 3 through the rotational locator 4, so that the opening direction of the hook can be adjusted according to the on-site situation to facilitate the entry of the wire. In order to achieve adjustment in any direction, the rotational locator 4 can be set as a rotational locator that can rotate 360 ​​degrees at will. The selection of the rotational locator 4 can select any one of the implementation methods in the prior art. The structure of the rotational locator 4 provided in the embodiment of the present application is as follows: Figures 5 to 8 Shown, the epimere of base bar 3 is installed on the rotation locator 4, and rotation locator 4 is connected with the hypomere of base bar 3 by rotation, on rotation locator 4, also be provided with clamping bolt 5, after adjusting the opening direction of hook, tighten clamping bolt 5 and the epimere of hook is fixed and can be used.In order to reinforce the ability of clamping bolt 5 clamping base bar 3, avoid clamping bolt 5 to loosen when external force occurs, base bar 3 cannot be clamped and positioned, can also increase spacer, spacer is arranged on the gap position between rotation locator 4 and the hypomere of base bar 3, and the rotation contact surface of spacer is adapted to the rotation contact surface of base bar 3, clamping bolt 5 and spacer can adopt the loose and non-loose mode, avoid clamping bolt 5 and spacer to become loose, cause spacer displacement fault.Certainly, spacer can also be fixed on the inwall of rotation locator 4, corresponding to the position of clamping bolt 5 all the time, can not cause sliding displacement.

[0049] For the use scenario of the hook in a humid environment, in order to prevent the hook from being corroded due to moisture, the material of the S-shaped hook 1 and the base rod 3 can be selected as stainless steel, which is strong and will not be damaged by corrosion and rust, affecting the service life of the hook.

[0050] To ensure the safety of the hook, the surface of the S-shaped hook 1 should be smooth and free of burrs.

[0051] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
