Description

Safety hook

The novel provides a safety hook, in particular, a novel technology capable of effectively increasing the hook opening and lengthening the locking rod in accordance with structural safety requirements, thereby making the overall operation more convenient and convenient.

In the environment where climbing, mountaineering, building construction, etc. are required to be lifted, safety hooks and safety belts must be used to ensure the safety of personnel.

Therefore, the creator developed the US Patent No. 81177721 "Hook Safety Device" invention patent. Because of its remarkable effect, the market responded well. However, the creator still did not complacent and found that the case was locked. When receiving the side impact force, the side impact force can only be transmitted to the hook body by a click portion, which is easy to stress concentration, and the length of the lock rod is greatly limited, so the hook mouth cannot be correspondingly enlarged, so that we are When engaging in hooking or unhooking, it cannot be put in place at one time, which not only increases the trouble of operation, but also greatly affects the value of the product.

In view of this, the creator has carefully researched and improved, and finally developed a new type that can effectively increase the hook and lengthen the lock bar to make the hooking or unhooking operation smoother and faster.

The present invention provides a safety hook comprising at least a hook body having a hook hole extending through a thickness, a first shaft hole, a guide groove, and a hook opening communicating the inside and the outside of the hook hole, the guide groove being the first shaft hole The arc center is arranged in an arc shape, and a clamping portion with a protruding thickness is further provided; a locking rod is provided with a side plate covering the guiding groove along the thickness of the hook body, and the two side plates further have a card edge matching the locking portion, and The first guiding hole is coupled with a guiding bolt extending through the guiding groove, so that the locking rod is rotated around the guiding bolt and the opening and closing hook opening that swings along the guiding groove, and when the locking rod locks the hook opening, the locking portion is The guide bolt can form a chain to bear the side impact force of the lock rod, and the main spring acts to actuate the lock rod so that the card edge abuts the retaining lock rod of the latch portion to close the hook opening; and a control rod is A main shaft is coupled to the first shaft hole, and a second guiding hole is coupled to the guiding bolt, so that the control rod can release the card edge release card when the interlocking locking rod rotates around the guiding bolt and swings along the guiding slot. The opening hook that allows the lock lever to swing.

Therefore, when the lock bar of the present type locks the impact side of the latching hook, the stress can be transmitted to the hook body through the latching portion and the guide bolt, and the main spring absorbs a part of the stress, so the present invention has the stress. The advantage of dispersion, in order to meet the structural safety requirements, effectively increase the hook and lengthen the lock bar to make the hook or unhook operation smoother and faster.

The two shielding plates 42 are disposed with a second shaft hole 43 at a position corresponding to the first shaft hole 14, so that the shielding plate 42 can be disposed. The second guide hole 45 is coupled to the second guide hole 45, and the second guide hole 45 is coupled to the guide hole 34. A latch 47 is coupled and the latch 47 is inserted through the guide slot 15 such that when the latch 30 closes the hook 110, the latch 47 abuts against the other end of the side plates 32, so that the latch 30 is locked. The second spring 48 is wound around the outer circumference of the main shaft 43 between the thickness 10C and the two shielding plates 42 respectively, and the second spring 48 is elastically abutted against the wall surface of the receiving slot 12. The third presser foot 481, another one is connected The fourth presser foot 482 of the inner surface of the end plate 41 can be pushed by a predetermined elastic force to make the end plate 41 away from the other side of the hook body 10 for maintaining the elastic engagement with the opening 120 and for urging the card edge 36. The latching portion 20 is abutted to further secure the locking lever 30 to close the hook opening 110.

Please cooperate with the sixth, seventh and eighth diagrams. When the first stage of the person presses the lever 40 to overcome the actuating lock lever 30 of the second spring 46, the lock lever 30 is rotated around the guide bolt 34 and guided along the guide. The slot 15 is swung in an arc to drive the card edge 36 to release The latch portion 20 and the latch 47 release the other ends of the side plates 32, and then, the retaining portion 37 can be moved along the limit of the latch portion 20 for maintaining the lock lever 30 to close the hook opening 110 as shown in FIG. When the person continues the second stage of the pressure control lever 40, as shown in the seventh figure, when the arc segment 38 is opposite to the click portion 20, the lock lever 30 can be completely released. As shown in the eighth figure, we can By pushing the lock lever 30, the double-guiding action of the guide bolt 34, the arc segment 38 and the latching portion 20 enables the lock lever 30 to stably and quickly open the hook opening 110 toward the hook hole 11. It is necessary to separately actuate the lever 40 and the lock lever 30 by both hands to open the hook 110, thereby effectively preventing the dangerous situation that the touch lever 40 or the lock lever 30 is accidentally opened.

More importantly, the present invention can transmit the stress to the hook body 10 through the latch portion 20 and the guide pin 34 when the lock lever 30 locks the side impact force of the hook port 110, and the main spring 35 and the second spring 46 It can absorb a part of the stress, so the present invention has the advantage of stress dispersion, so as to effectively increase the hook opening 110 and the extended locking rod 30 in accordance with the structural safety requirements, so as to make the hooking or unhooking operation smoother and fast.
