Description

Technical Field

[0001] This utility model belongs to the field of hook technology, and in particular relates to a portable, small, automatic unhooking hook. Background Technology

[0002] Lifting hooks are widely used for lifting objects. They are equipped with anti-disengagement mechanisms, typically using a spring-loaded anti-disengagement plate hinged to the hook opening to prevent the lifting equipment from detaching from the hook during lifting and causing accidents. However, current anti-disengagement structures require manual release after lifting is complete. A person needs to rotate the anti-disengagement plate to remove the lifting equipment from the hook. When lifting operations are frequent, workers need to constantly enter and exit the lifting area. If other lifting operations are also underway, this can easily lead to accidents. Waiting for other lifting operations to complete before releasing the hook reduces work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a portable, small, automatic unhooking hook to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A portable, small, automatic release hook includes a load-bearing box, a vertical plate hinged to the top of the load-bearing box, a first pin mounted on the vertical plate, a hook body hinged to the bottom of the load-bearing box, a spring connecting one side of the hook body to the load-bearing box, an anti-detachment plate hinged on the load-bearing box, a connecting rod hinged on the anti-detachment plate, and the connecting rod hinged to the hook body.

[0006] Furthermore, the load-bearing box has an opening on one side and at the bottom. A fixing rod is welded inside the lower part of the opening side of the load-bearing box, and a hanging ring is welded on the fixing rod.

[0007] Furthermore, the hook body is hinged inside the load-bearing box via a second pin that passes through the load-bearing box and the hook body. The opening of the hook body faces away from the open side of the load-bearing box. A lifting ring is welded to the outside of the hook body, and the two ends of the spring are fixed to the lifting rings of the load-bearing box and the hook body, respectively.

[0008] Furthermore, the anti-detachment plate is located on the side of the load-bearing box near the opening of the hook body, and there are two connecting plates, which are located on both sides of the hook body.

[0009] Furthermore, there are two uprights, located on both sides of the load-bearing box. The bottom ends of the two uprights are hinged to the load-bearing box via a third pin that passes through both uprights and the load-bearing box.

[0010] Furthermore, a support plate is welded between the two upright plates, and a first pin is installed through the top of the two upright plates.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model can automatically unhook without manual operation, reducing workload and improving the safety of hoisting operations.

[0013] 2. The anti-detachment plate can rotate synchronously with the hook body. When no object is being lifted, there is no obstruction in front of the hook body, making it easy for the lifting equipment to be hooked. When lifting an object, the anti-detachment plate stands upright to prevent the lifting equipment from detaching from the hook. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0020] like Figure 1-4 As shown, a portable small automatic release hook includes a load-bearing box 1, a vertical plate 2 hinged to the top of the load-bearing box 1, a first pin 3 mounted on the vertical plate 2, a hook body 4 hinged to the bottom of the load-bearing box 1, a spring 5 connecting the hook body 4 to the load-bearing box 1 on one side, an anti-detachment plate 6 hinged to the load-bearing box 1, a connecting rod 7 hinged to the anti-detachment plate 6, and the connecting rod 7 hinged to the hook body 4.

[0021] The load-bearing box 1 has an open side and bottom. A fixing rod 8 is welded inside the lower part of the open side of the load-bearing box 1, and a hanging ring 9 is welded on the fixing rod 8.

[0022] The hook body 4 is hinged inside the load-bearing box 1 by a second pin 10 that passes through the load-bearing box 1. The opening of the hook body 4 faces away from the open side of the load-bearing box 1. A lifting ring is welded to the outside of the hook body 4. The two ends of the spring 5 are respectively fixed to the lifting ring of the load-bearing box 1 and the hook body 4.

[0023] The anti-detachment plate 6 is located on the side of the load-bearing box 1 near the opening of the hook body 4. There are two connecting plates, located on both sides of the hook body 4. When the anti-detachment plate 6 is in the upright position, its bottom end is inside the hook body 4, thus preventing the lifting device from detaching from the hook body 4. At the same time, when the anti-detachment plate 6 is in the upright position, one side of the anti-detachment plate 6 is close to the inner wall of the load-bearing box 1, thus preventing the anti-detachment plate 6 from continuing to rotate. That is, the top end of the anti-detachment plate 6 is limited by the load-bearing box 1, and the bottom end of the anti-detachment plate 6 is limited by the hook body 4, thus preventing the lifting device from detaching.

[0024] There are two upright plates 2, which are located on both sides of the load-bearing box 1. The bottom ends of the two upright plates 2 are hinged to the load-bearing box 1 through a third pin 11 that passes through the two upright plates 2 and the load-bearing box 1.

[0025] A support plate 12 is welded between the two upright plates 2, and a first pin 3 is installed through the top of the two upright plates 2.

[0026] The working principle of this utility model is as follows:

[0027] In use, this utility model is attached to the hook of the lifting equipment via the first pin 3. Since the spring 5 is in a contracted state, it pulls the hook body 4 upwards, leaving the opening of the hook body 4 unobstructed. At this point, the hook body 4 can be attached to the lifting device for the object. When lifting upwards, the weight of the object pulls the hook body 4 downwards, making the hook upright. Simultaneously, it pulls the spring 5, causing it to extend. During this process, due to the hinge of the connecting rod 7, the anti-detachment plate 6 is rotated to an upright position and locked inside the hook body 4. The lifting device is then blocked by the anti-detachment plate 6 and will not detach from the hook body 4. After the object is lifted to the designated location, the hook body 4 loses the pull of the object. Under the tension of the spring 5, the hook body 4 rotates. Simultaneously, under the hinge of the connecting rod, the anti-detachment plate 6 also rotates upwards, again leaving the opening of the hook body 4 unobstructed, thus facilitating the attachment of the lifting device inside the hook body 4.

[0028] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.

[0029] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
