[0023] like Figure 1-7As shown, the utility model discloses a hook lock switch, comprising: an elephant trunk lock body 1 and a locking member 2. The elephant trunk lock body 1 comprises a shell 3. The head edge of the shell 3 is movably connected to a rotating block 5. The rotating block 5 is movably connected to the head edge of the shell 3 and cooperates with the locking member 2 to realize the unlocking and locking function of the overall structure. The right side of the inner wall of the shell 3 is movably connected to a lock buckle 4. The rotating block 5 is fan-shaped, and the side close to the center of the circle is connected to the shell 3 through a middle rivet 10. The rotating block 5 is installed with a middle rivet 10 near the middle of the center of the circle and is movably connected to one side of the shell 3 through the middle rivet 10. When working, it rotates around the center of the circle at a limited angle. The outer wall of the middle rivet 10 is provided with a large torsion spring 8, one side of the large torsion spring 8 abuts against the outer shell 3, and the other end abuts against the rotating block 5. The rotation of the rotating block 5 mainly relies on the force arm of the large torsion spring 8 abutting against it. The upper inner side of the rotating block 5 is bent inward with a clamping angle 20. The outer side of the rotating block 5 is connected to the roller 9 through the rotation of the middle rivet 10. The head of the lock buckle 4 is movably installed in the outer shell 3 through the middle rivet 10. The outer wall of the middle rivet 10 is provided with a small torsion spring 7, one end of the small torsion spring 7 abuts against the fixed block 6, and the other end is hung with the lock buckle 4. The tail of the lock buckle 4 is provided with a restriction area 13 for limiting the rotation of the clamping angle 20.
[0024] The restricted area 13 includes: a positioning area 14, a slide rail area 15 and a safety hook 16. The positioning area 14 is opened on one side of the lock 4 and is set in a semicircular arc to limit and guide the clamping angle 20 to move in the restricted area 13. The slide rail area 15 is set on one side of the positioning area 14 and is conical. It is used to move the clamping angle 20 in the restricted area 13 to drive the rotating block 5 to move. The upper side of the slide rail area 15 and the positioning area 14 form an open groove 17. The safety hook 16 is set in the slide rail area 1 5, and the left side of the slide rail area 15 and the safety hook 16 form a limiting groove 18. The safety hook 16 is used to limit the clamping angle 20 from leaving the limiting groove 18, and both sides of the safety hook 16 are inclined to facilitate the movement of the clamping angle 20 along the side of the safety hook 16. The locking member 2 is vertically arranged and has a long mounting hole in the vertical direction. The top of the mounting hole is provided with a fixing groove 19 that cooperates with the roller 9. The fixing groove 19 is semicircular and can half cover the roller 9 to strengthen the fixing effect.
[0025] The lower side of the clamping angle 20 is tilted inward, and a limiting hook 21 is provided at the outer end of the side. The limiting hook 21 and the lower side of the clamping angle 20 form a positioning groove 22, and the positioning groove 22 is slidably engaged with the positioning area 14 and the slide rail area 15.
[0026] The shell 3 includes: a right wall 23, a left wall 24 and a first connecting wall 25. The right wall 23 and the left wall 24 are connected by the first connecting wall 25, and the whole is stamped into a U-shaped sheet metal. The internal open end of the shell 3 is movably connected to the fixed block 6 through a large rivet 11.
[0027] The rotating block 5 includes: a right side wall 26, a left side wall 27 and a second connecting wall 28. The right side wall 26 and the left side wall 27 are connected by the second connecting wall 28. A limited angle 29 is set at the tail of the second connecting wall 28 where it abuts the shell 3 so that the rotating block 5 can rotate along a fixed angle. One end of the medium rivet 10 passes through the shell 3, the right wall 23 and the rotating block 5, the right side wall 26, and the large torsion spring 8 to extend to the left side wall 27 of the rotating block 5, and passes through the left wall 24 of the shell 3 to form a riveted connection. One end of the small rivet 12 passes through the right side wall 26, passes through the roller 9 and extends to the left side wall 27 to form a riveted connection.
[0028] The working principle of this hook lock switch is described in detail below.
[0029] like Figure 1-7 As shown, when in use, the fixing groove 19 of the adjustment lock member 2 is contacted with the roller 9, and the roller 9 is moved downward to be squeezed to the roller 9, and then the rotary block 5 is rotated around the hinge point, and the roller 9 is contacted with the fixing groove 19 to realize rotational locking. At the same time, the lock tongue 4 is driven to rotate by the small torsion spring 7 to contact the clamping angle 20 to realize locking. When unlocking, the lock member 2 is moved upward to cause the roller 9 to disengage from the limit of the fixing groove 19. Under the action of the large torsion spring 8, the rotary block 5 can be pulled to reset to the inside of the shell 3 to realize storage and improve the storage effect. At the same time, by pressing on the rotary block 5, the lock buckle 4 is caused to disengage from the clamping angle 20 and reset under the action of the small torsion spring 7.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the utility model, and such improvements and modifications should also be considered within the scope of protection of the utility model. Any components not specified in this embodiment may be implemented using existing technologies.
