[0025] The specific implementation of the utility model will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.
[0026] like Figures 1 to 6 As shown, the damping hook includes a shell 1 and a hook plate 2. The shell is an open hollow structure. The inner side of one end of the hook plate is hingedly connected to the shaft hole 101 of the shell through a pin shaft, and the inner side of the other end of the hook plate is provided with a hook part 201 for hanging objects; the hook plate is integrated on the shell to form an assembly structure, which is convenient for automobile installation; when the hook plate is in the retracted state, it is completely located in the shell and there is no safety hazard; after the hook plate is flipped open, the hook part at the other end of the hook plate is exposed to the outside, which is convenient for hanging objects.
[0027] A pin torsion spring 4 is provided on the pin shaft for popping out after the hook plate is unlocked; a lock plate 202 is extended inwardly at the hinged end of the hook plate, and a circulation groove for locking and unlocking is provided on the lock plate. An associated limit hook 3 is provided on the shell corresponding to the circulation groove, and a damping structure is provided corresponding to the pin shaft.
[0028] The damping hook structure of the utility model is reasonably designed. The locking structure is integrated on the hook body, and a limit hook is correspondingly arranged on the shell. The heart-shaped circulation groove of the locking structure is used to realize pressing to pop out and fold up. There is no need to set a locking structure separately, the structure is simple, and the cost is relatively low.
[0029] Preferably, the circulation groove is a heart-shaped circulation groove, the limiting hook 3 is a torsion spring, and a mounting column 103 for positioning the torsion spring is provided on the outside of the shell. This torsion spring is sleeved on the mounting column 103, and a movable hole 102 is provided on the shell corresponding to the lock plate. One end of the torsion spring passes through the movable hole corresponding to the heart-shaped circulation groove. The integrated setting has a simple structure.
[0030] A positioning groove 106 for positioning the other end of the torsion spring is provided on the outside of the shell. The positioning groove is located above the mounting column. The positioning groove is an open groove, and the other end of the torsion spring is easily positioned. The end of the positioning column is used for a convex card 104 for limiting the torsion spring to prevent the torsion spring from falling off, and the structure is stable and reliable.
[0031] Furthermore, a limit card 105 is provided on the outer side of the shell near one end of the torsion spring for limiting the range of movement of one end of the torsion spring; the limit card is located between the mounting column and the movable hole, and the limit card is a strip rib with an opening at the lower end, which limits the movement of the limit hook, and the unlocking or locking operation is stable.
[0032] The damping structure is a hollow damper 5; preferably, the damper 5 is a damping sleeve structure, and the pin shaft is arranged through the damping sleeve structure; the hinged end of the hook plate is provided with a damping mounting portion for placing the damper, and the damping mounting portion is a hollow structure with one side open, and the damping sleeve structure is installed in the hollow structure and integrated in the hinged end of the hook plate, and the structure is compact;
