Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically a novel grab hook used for tensioning and adjusting the length of a circular chain when binding objects with a circular chain. Background Technology

[0002] In industrial production or transportation, circular chain links are commonly used to bind or hoist products, and accessories such as tensioners or swivel adjusters are used to tension the chain. Tensioners have limited travel, and swivel adjusters are prone to disengagement after impact.

[0003] To address the above issues, a novel gripper hook suitable for binding circular links is proposed. This hook is used to tension the circular links and features easy disassembly, simple operation, and the ability to be installed at any position on the chain. Summary of the Invention

[0004] This invention proposes a novel gripper hook suitable for binding circular chain. When binding objects with a circular chain, the chain can be quickly tensioned and its length can be quickly adjusted. The operation is simple.

[0005] To achieve the above-mentioned functions, the present invention adopts the following technical solution: A novel gripper hook suitable for binding circular links includes: hook body 1, locking pin 2, spring 3, and threaded end cap 4; the locking pin 2 is provided with a head rod 2-1, a retaining ring 2-2, and a tail rod 2-3; Locking pin 2, spring 3, and threaded end cap 4 are all installed on hook body 1. First, locking pin 2 is installed in stepped hole 1-4, spring 3 is installed on tail rod 2-3, and tail rod 2-3 is inserted into through hole 4-1. Retaining ring 2-2 and threaded end cap 4 will lock spring 3. Finally, threaded end cap 4 is installed in threaded hole 1-5.

[0006] During operation, first hook the chain link with the hook opening 1-1, then pass the other end of the circular chain through the eyelet 1-2 to tension the chain. Next, pull the locking pin 2 and hook the chain link with the tail opening 1-3. Then release the locking pin 2, which returns to its original position under the action of the spring 3 and locks the chain link, preventing it from falling off during operation. After the operation is completed, pull the locking pin 2 again to remove the chain link on the tail opening 1-3, then release the locking pin 2 and return it to its original position under the action of the spring 3. Then remove the chain link on the hook opening 1-1, and finally remove the circular chain from the eyelet 1-2. The operation is quick and simple, requires no tools, and is highly safe.

[0007] This utility model has the following beneficial effects: 1. This utility model can be quickly installed or disassembled at any position of the circular link chain, and the operation process is simple.

[0008] 2. This utility model can quickly tension the circular link chain, and has a high level of safety. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] As attached Figure 1 To be continued Figure 6 The present invention relates to a novel gripper hook suitable for binding circular links, comprising a hook body 1, wherein the hook body 1 is provided with a hook head opening, a ring eye, a tail opening, a stepped hole and a threaded hole, a locking pin 2 is installed in the stepped hole, a spring 3 is installed on the tail rod of the locking pin 2, and the tail rod is inserted into the through hole of the threaded end cap 4, the spring 3 is held in place by the retaining ring and the threaded end cap 4, and finally the threaded end cap 4 is installed on the threaded hole.

[0013] The working principle of this utility model is as follows: During operation, firstly, the hook head opening hooks the chain link, then the other end of the circular chain is passed through the eyelet and the chain is tensioned. Next, the locking pin 2 is pulled and hooked onto the chain link using the tail opening. Then, the locking pin 2 is released, and it resets under the action of the spring 3, locking the chain link and preventing it from falling off during operation. After operation, the locking pin 2 is pulled again to remove the chain link from the tail opening. Then, the locking pin 2 is released and reset under the action of the spring 3. The chain link on the hook head opening is then removed, and the circular chain inside the eyelet is taken off.

[0014] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
