TECHNICAL FIELD

[0001] The utility model relates to the technical field of clutch, concretely is a gear clutch for automatic unhooking. BACKGROUND

[0002] In the field of hoisting, transportation, hooks are widely used. The traditional hook picking and hanging operation usually needs to be completed manually, and there are problems such as complicated operation, high labor intensity, and low efficiency. In order to solve these problems, various automatic hook picking and hanging devices have appeared. However, the existing automatic hook picking and hanging devices have complex structure and high cost, and the motor and other electrical components are easily damaged under overload condition.

[0003] Therefore, the present application provides a gear clutch for automatic unhooking to solve the technical problems existing in the prior art. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims to provide a gear clutch for automatic unhooking which has simple structure, low cost, can protect electrical components, and can easily pick and hang hooks in any state.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A gear clutch for automatic unhooking, comprising a gear and a shaft, characterized in that:

[0007] The gear is internally provided with at least one elastic body, which can be embedded in the groove on the surface of the hook;

[0008] The shaft is an optical axis, passing through the gear and the hook;

[0009] The surface of the hook is provided with a groove matched with the elastic body, and the number, shape and distribution of the groove are designed according to actual requirements;

[0010] The gear clutch is used to avoid damage of the engineering motor caused by overload.

[0011] Further, the elastic body is a spring, a rubber block or an elastic metal body.

[0012] Further, the gear is internally provided with a plurality of elastic bodies uniformly distributed in the circumferential direction.

[0013] Further, the groove on the surface of the hook is a special-shaped groove, a V-shaped groove, a U-shaped groove, a hemispherical groove or a rectangular groove.

[0014] Further, the material of the gear is copper, steel, aluminum alloy or engineering plastic.

[0015] Further, the material of the hook is steel or alloy steel.

[0016] Furthermore, the material of the elastomer is rubber or elastic metal.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This application features a simple structure, ease of manufacture and maintenance, and low cost. It allows for bidirectional clutch engagement, effectively protecting electrical components from overload damage. It enables easy hooking and unhooking in any state, ensuring safe operation, short operation time, and low labor intensity. By selecting appropriate elastomer materials and groove shapes, the clutch torque can be adjusted to meet the needs of different application scenarios. Bearings are used to reduce friction, improving transmission efficiency and service life. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0020] Figure 2 This is a schematic diagram of an embodiment of the present invention.

[0021] In the diagram: 1. Gear; 2. Elastomer; 3. Shaft; 4. Hook. Detailed Implementation

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] like Figure 1 , Figure 2 As shown, a gear clutch for automatic disengagement includes a gear 1 and a shaft 3. The gear 1 has multiple elastic bodies 2 evenly distributed along its circumference inside, each elastic body 2 being a spring. The hook 4 has hemispherical grooves on its surface that mate with the elastic bodies 2. The shaft 3 is a smooth shaft that passes through the gear 1 and the hook 4. The gear 1 is made of steel, and the hook 4 is made of alloy steel.

[0024] More preferably, the elastomer 2 is a rubber block or an elastic metal body; the groove on the surface of the hook 4 is an irregular groove, a V-shaped groove, a U-shaped groove, or a rectangular groove; the material of the gear 1 is copper, aluminum alloy, or engineering plastic; the material of the hook 4 is steel; and the material of the elastomer 2 is rubber or other elastic metal body.

[0025] Working principle:

[0026] The power source (not shown in the figure) drives the gear 1 to do the circumferential motion, the elastic body 2 in the gear 1 is embedded in the groove on the surface of the hook 4, drives the hook 4 to do the up and down motion together. When the hook 4 works and is static, the gear 1 continues to move, the elastic body 2 slides in the groove, thereby skids, plays the role of protecting the motor.

[0027] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but rather can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being defined by the appended claims rather than that of the above description, and it is intended to embrace all changes and modifications that fall within the meaning and scope of equivalents of the claims. Any reference signs in the claims should not be construed as limiting the claims to the figures in which the reference signs are used.
