DETAILED DESCRIPTION

[0017] In order to make the technical personnel of the technical field better understand the present utility model scheme, the technical scheme in the present utility model embodiment will be clearly and completely described below in conjunction with the drawings in the present utility model embodiment. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by the technical personnel in the technical field belonging to the present utility model. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order.

For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] like Figure 1 , Figure 3 As shown, a lifting hook for lifting equipment that is easy to install includes a lifting hook body 2 and a connecting seat 1. The connecting seat 1 is an inverted shaped structure. The two sides of the lifting hook body 2 are provided with connecting shafts 21. The two sides of the connecting seat 1 are provided with U-shaped bayonet holes 3 for the connecting shaft 21 to be opened. The U-shaped bayonet holes 3 are arranged to be inclined downward from front to back. Preferably, the inclination angle of the U-shaped bayonet holes 3 is 45°. A clamping plate 4 is provided on the outer side of the connecting seat 1. One end of the clamping plate 4 is hinged to the connecting seat 1. The lower part of the other end of the clamping plate 4 is provided with a clamping portion 31 that cooperates with the arc portion of the U-shaped bayonet hole 3 to clamp the connecting shaft 21. An L-shaped seat body 6 is provided on the outer side of the connecting seat 1. A locking assembly 5 for locking the clamping plate 4 is provided on the L-shaped seat body 6.

[0020] like Figure 4 As shown, the engaging portion 31 includes an inclined transition section 311, an arcuate engaging section 312 and a linear limiting section 313 arranged in sequence, and the arcuate engaging section 312 engages the connecting shaft 21 with the arcuate portion of the U-shaped bayonet 3. The engaging portion 31 is a hook-shaped structure, which can effectively cooperate with the U-shaped bayonet 3 to engage the connecting shaft 21.

[0021] like Figure 2As shown, the locking assembly 5 includes a screw 52, ​​a hand wheel 51 and a clamping column 53. The screw 52 passes through the L-shaped seat body 6 and is threadedly connected to the L-shaped seat body 6. One end of the screw 52 is connected to the hand wheel 51, and the other end of the screw 52 is connected to the clamping column 53. The clamping plate 4 is provided with a clamping groove 32 that cooperates with the clamping column 53. When in use, the screw 52 is rotated by the hand wheel 51 to make the clamping column 53 clamped in the clamping groove 32, thereby locking the clamping plate 4.

[0022] like Figure 5 As shown, a limiting plate 211 is provided at the outer end of the connecting shaft 21 to play a limiting role and prevent the connecting shaft 21 from deviating too much to the left and right.

[0023] When in use, the connecting shaft 21 of the lifting hook body 2 is inserted into the U-shaped bayonet 3 on both sides of the connecting seat 1, and the clamping plate 4 is rotated clockwise around the hinge point so that the clamping portion 31 of the clamping plate 4 cooperates with the arc portion of the U-shaped bayonet 3 to clamp the connecting shaft 21, and then the screw 52 is rotated so that the clamping column 53 on the screw 52 is inserted into the clamping groove 32 on the clamping plate 4 to achieve the locking of the clamping plate 4, thereby forming a hinged structure between the lifting hook body 2 and the connecting seat 1. This structure is convenient for disassembly and assembly, and the disassembly and assembly process does not require the aid of tools. Since the lifting hook body and the connecting seat form a hinged structure, when hooking an object, it is only necessary to rotate the lifting hook body, which is relatively light and easy to operate.

[0024] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
