Enhanced type safety hook

Abstract

The invention discloses an enhanced type safety hook, comprising a hook body, a locking rod, a control handle and a spring, wherein the hook body is provided with a hook hole, a mouth seat, a pin groove and a rail groove; the hook hole is provided with a hook opening; the mouth seat is formed at the top end of the hook opening; the pin groove is positioned under the hook opening; the locking rod is a door-shaped frame formed by a main plate and two edge plates; a blocking edge is bridged on the top edges of the two edge plates, so that a mouth shape can be formed on the top edge of the locking rod, and the top edge of the locking rod is sheathed at the periphery of the mouth seat; the two edge plates are also fixedly provided with a rail rod matched with the rail groove and a main pin piece matched with the pin groove; the main pin piece can slide along the pin groove; the spring actuates the locking rod, so that the locking rod has the trend of locking the hook hole anytime; and the control handle is connected with the hook body by a pivoting shaft in a pivoting manner and is provided with a rotating hole which is used for enabling the main pin piece to rotate by self in a pivoting manner, so that the control handle drives the main pin piece to switch the position along the pin groove. Therefore, the enhanced type safety hook disclosed by the invention has the advantages that higher safe use requirement is met, the deformation condition of the locking rod can be reduced to be lowest, and the reusability is improved.

Description

technical field [0001] The invention relates to a reinforced safety hook, and more specifically refers to a special technology that can greatly improve the side impact force of a lock bar. Background technique [0002] In order to solve the problem that the lock bar of the traditional safety hook bears insufficient stress, the inventor has just developed the safety hook patent case No. 098221304 of Taiwan, China. However, the inventor is still not complacent with this, and finds that the lock of the previous patent case The top end of the rod is pivoted on the hook body by the first shaft, while the bottom end bounces against the inner side of the hook mouth, causing the bottom end of the lock rod and the bottom of the hook mouth to be unable to withstand the force, so the lock rod is subjected to When there is a side impact force in the direction of the hook mouth, the lock bar must be engaged with the tenon groove of the control bar through a mortise shaft in order to tran...

[0002] In order to solve the problem that the lock bar of the traditional safety hook bears insufficient stress, the inventor has just developed the safety hook patent case No. 098221304 of Taiwan, China. However, the inventor is still not complacent with this, and finds that the lock of the previous patent case The top end of the rod is pivoted on the hook body by the first shaft, while the bottom end bounces against the inner side of the hook mouth, causing the bottom end of the lock rod and the bottom of the hook mouth to be unable to withstand the force, so the lock rod is subjected to When there is a side impact force in the direction of the hook mouth, the lock bar must be engaged with the tenon groove of the control bar through a mortise shaft in order to transfer the side impact force of the lock bar to the hook body. The side impact force cannot be released to the hook body nearby, so that the side impact force must be transmitted through the top of the lock rod and the tenon shaft. The transmission path of the side impact force to the lock rod is too long, which will easily cause the lock rod to collapse and deform, resulting The overall structure has concerns that it cannot be reused
