Description

Safety hook structure improvement

This creation is about a safety hook, especially for a safety hook structure with a double buckle that can be quickly equipped and stably locked.

The use of hooks on the market is quite extensive. In addition to lifting heavy objects, the application surface of the rope operation can be amplified, and the strength of the ropes can be increased. It can really improve the efficiency of various operations, especially in rock climbing and drooping. When lifting work or high-altitude bounce, etc., the structure of the hook itself is more and more particular, not just the strength and application.

Referring to the first figure, the first figure shows a schematic view of the appearance of the conventional hook. As shown in the figure, the conventional hook 100a is mainly composed of a ring body 1a and a locking portion 2a, wherein the ring body 1a itself has an opening. The end of the pivotal locking portion 2a is movably fastened to the other end of the ring body 1a, thereby forming a hook and loop of the hook; and the locking portion 2a can provide a locking when the rope is wound around the ring body 1a, so that the rope It is not easy to be detached from the opening of the ring body 1a; however, although the above design has the effect of stable locking, it is necessary to first wind the one end rope after the operation, then turn the conventional hook 100a to wind the other end rope, and finally lock. The buckle part 2a is locked to complete the equipment, and the process is too complicated and the effect is not good, and it cannot be dealt with in an emergency.

In view of this, the creators of this case specially provide a double-loop, and can quickly and equitably stabilize the safety hook structure, which is derived from the structural design of the custom-linked structure. After years of painstaking research, I finally succeeded in researching and developing this creation.

The utility model relates to a safety hook structure improvement, which is mainly composed of a hook body and a lock brake; the hook system has an open annular structure, and a middle portion is further provided with a partition portion, which is further divided into a hook portion and a hook portion; a pivotable pivot bolt at the middle portion of the lock brake is pivotally disposed at the end of the partition portion, and upper and lower ends thereof are respectively detachably engaged with the upper and lower ends of the hook body opening to form two Closed loop structure.

The safety hook structure is improved as described above. Preferably, the locking mechanism is pivotally disposed at an intermediate portion of the end of the partition portion to further provide an elastic member for maintaining the hook body in a closed loop structure.

The safety hook structure is improved as described above. Preferably, the upper end of the latching shutter is further provided with a fastening component and two pressing switches, and the fastening component is telescopically coupled to the hook opening by an elastic component. The upper end, and the two push switches are used to lock the fastening component to stop stretching.

The safety hook structure is improved as described above. Preferably, the lower end of the latching shutter is further provided with a recess corresponding to a convex portion disposed at a lower end of the hook opening.

As described above, the safety hook structure is improved. Preferably, the upper and lower ends of the latching shutter are unidirectionally engaged with the upper and lower ends of the hook body.

With the above structural design, the creation first unlocks the lock brake, and then directly wraps the ropes at both ends on the hook portion and the lower hook portion of the hook body, and finally closes the lock brake to complete the equipment. Quickly and safely and securely, it is quite novel and progressive compared to the design of the conventional hook structure.

In order to make it easier for the reviewing committee to understand the other features and advantages of this creation, and the effect achieved by it, it will be more detailed. The following figure will be described in detail with reference to the following figures: Please refer to the second to fourth figures. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 3 is a schematic exploded view showing the preferred embodiment of the present invention; the fourth drawing shows an internal cross-sectional view of the preferred embodiment of the present creation; and the fifth figure shows the best of the present creation. A state diagram of the use of the embodiment.

As shown in the figure, the creation safety hook structure improvement 100 is mainly composed of a hook body 1 and a lock brake 2; the hook body 1 is an annular structure having an opening, and a partition portion 11 is further provided at the middle portion. Further, it is divided into an upper hook portion 12 and a lower hook portion 13; a pivotable pivot bolt is pivoted at the end of the partition portion 11 at the middle portion of the lock gate 2, and the upper and lower ends are respectively connected with the hook body 1 The upper end and the lower end are detachably engaged with each other to form a two-closed annular structure.

As shown in the figure, the lock ring 2 of the present invention is pivotally disposed at a middle portion of the end of the partition portion 11 and further provided with an elastic member 21. In the preferred embodiment of the present invention, the elastic member 21 is a spring for the hook body. 1 maintaining a two-closed annular structure; in addition, the upper end of the latching brake 2 is further provided with a fastening component 22 and two pressing switches 23, 24, and the fastening component 22 is telescopically coupled to the hook body by an elastic component 25 1 The upper end of the opening, in the preferred embodiment of the present invention, the elastic member 25 is a spring piece, and the two pressing switches 23, 24 are used to lock the fastening member 22 to stop the expansion and contraction.

As shown in the figure, the lower end of the lock gate 2 of the present invention is further provided with a recess 26 corresponding to one of the convex portions 131 provided at the lower end of the opening of the hook body 1. In addition, the upper and lower ends of the lock gate 2 are unidirectional. The upper and lower ends of the hook body 1 are detachably engaged with each other.

With the above structural design, the creation safety hook structure improvement 100 only needs to first open the lock gate 2 in the operation, and then directly wrap the two ends of the rope directly on the hook portion 12 and the lower hook portion 13 of the hook body, and finally lock The brakes are closed and the equipment can be completed. The process is quick and secure, and it can maintain its advantages in the event of an emergency. It is quite novel and progressive.

The detailed description above is a detailed description of one of the possible embodiments of the present invention, and the embodiment is not intended to limit the scope of the patents, and the equivalent implementations or modifications that are not included in the spirit of the present invention should be included in The patent scope of this case.

On the whole, this case is not only innovative in terms of technical thinking, but also able to enhance the above-mentioned functions more than the customary items, and should fully comply with the statutory creation of novelty and progressiveness. Patent requirements, 提出 apply in accordance with the law, please ask your office to approve this new type of patent application, to encourage creation, to the sense of virtue.
