Embodiment Construction

[0016] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. A preferred embodiment of the invention is shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0017] see Figure 1~Figure 4 The self-locking hook shown includes a hanging lug 1, a load-bearing platform 2, a hook 3, a lock 4 and a lock cylinder 5, and the hanging lug 1, the bearing platform 2 and the hook 3 are integrally cast to obtain a firm main body of the hook. Ear 1 is used for connecting hanging ring, and hanging ring is connected on the hoisting device by hanging rope. The load-bearing platform 2 is the central area of ​​the hook, and other parts of the hook are connected to the lo...

Abstract

The invention discloses a self-locking lifting hook, and belongs to the field of engineering lifting appliances. The self-locking lifting hook comprises a suspension loop, a load-bearing platform, a hook, a lock catch and a lock cylinder, wherein the load-bearing platform is the central region of the lifting hook; the other parts of the lifting hook are connected to the load-bearing platform; thehook is located under the load-bearing platform, and is the combination region of the lifting hook and an object; the object can be hung on the hook; one side of the hook is an opening region; the lock catch is arranged at the opening region, and is mounted on the load-bearing platform through a pin; the lock catch can rotate around the pin; when the lock catch rotates to fit the hook, the self-locking action of the lifting hook is realized, and the object hung on the lifting hook cannot slip off the lifting hook. According to the self-locking lifting hook disclosed by the invention, the strength of a self-locking mechanism of the lifting hook is equivalent to that of a main lifting hook; a manually-opened dialing piece is mounted on the self-locking mechanism, the firm self-locking lifting hook is obtained.

Description

technical field [0001] The invention relates to the field of engineering hangers, in particular to a self-locking hook. Background technique [0002] The engineering field often needs to face large and heavy operation objects. At this time, the spreader is a commonly used tool, and the hook on the spreader is an important part of the spreader. Among them, the hooks that need to be handled with special care are The anti-slip problem, on the one hand, the hook must have sufficient strength, on the other hand, the hanging of the hook must be stable to prevent the item from slipping off the hook during the lifting process. For this reason, a variety of self-locking hooks have been developed in the engineering field. The most common self-locking method is to set a spring card in the opening area of ​​the hook. The lanyard bounces from the outside to the inside. Return to the original position under the action of the hook, and lock the opening area of ​​the hook to realize the se...
