Abstract

The utility model discloses a sucker type hook, which comprises a pedestal and a sucker. The sucker is arranged on the pedestal. A through hole is formed in the pedestal. A piston is arranged in the through hole. A sealing ring is arranged between the piston and the wall of the hole. The piston is provided with a piston rod which is extended out of the hole. A pressing cap is molded at the outer end of the piston rod. A resetting spring is sleeved on the piston rod, and is compressed between the pressing cap and the pedestal. The sucker type hook has the advantages that: the piston is arranged in the pedestal, and the volume of air in the sucker is changed by the sliding of the piston to increase a negative pressure and make the atmosphere produce high pressure on the sucker, so that the sucker is reliably pressed on a suction object, and a suction force is improved.

Description

The sucker-type hook

Technical field:

The utility model relates to a kind of sucker-type hook.

Background technique:

Even if disassemble from being adsorbed object, can there be any vestige in the sucker-type hook on the former absorbent bodies owing to have seamless characteristics; Make it obtain consumers in general favor, existing sucker-type hook principle is, when the sucker-type hook is pressed against when being adsorbed on the object; Part air in the sucker is discharged from, and forms negative pressure in the sucker, under atmospheric pressure effect; Sucker finally is crushed on the absorbent bodies, but sometimes because operator presses sucker power when not enough, and the air in the sucker is discharged when not enough; Negative pressure in the sucker is not enough, will cause the sucker actual effect, and whole hook can drop.

Summary of the invention:

The purpose of the utility model is in order to overcome the shortcoming of above-mentioned existing technology, a kind of sucker-type hook that improves adsorption force to be provided.

For realizing above-mentioned purpose, the technological scheme that the utility model provides is: the sucker-type hook includes pedestal and sucker; Sucker is installed on the pedestal, on pedestal, forms through hole, is provided with piston in the through hole; Be provided with seal ring between plug and the hole wall, piston is provided with the piston rod that stretches out in the hole, forms pressure cap in the outer end of piston rod; Be connected to Returnning spring at upper cover of piston rod, Returnning spring is compressed between pressure cap and the pedestal.

After improving, through in pedestal, being provided with a piston, utilize the slip of piston, change the volume of air in the sucker, thereby improve negative pressure, make atmosphere produce bigger pressure to sucker, make the sucker absorbent bodies more reliable, improved adsorption force.

Description of drawings:

Fig. 1 is the structural representation of the utility model hook;

Fig. 2 is that the utility model is linked up with the structural representation when preparing to be adsorbed on the absorbent bodies;

Fig. 3 is the structural representation after being adsorbed on the object of being pressed of the utility model hook.

Embodiment:

Combine accompanying drawing to set forth the utility model in detail at present:

The sucker-type hook of present embodiment includes pedestal 1 and sucker 2, and sucker 2 is installed on the pedestal 1, on pedestal 1, forms through hole 3; Be provided with piston 4 in the through hole 3; Be provided with seal ring 5 between piston 4 and the hole wall, piston 4 is provided with the piston rod 6 that stretches out in the hole, forms pressure cap 7 in the outer end of piston rod 6; On piston rod 6, be socketed with Returnning spring 8, Returnning spring 8 is compressed between pressure cap 7 and the pedestal 1.

When using hook, the sucker 2 of sucker-type hook towards being adsorbed object 9 surfaces, is pushed pressure cap 7 then; In the time of sucker 2 discharge section gases, piston 4 is pressed towards pedestal 1 inside, then unclamps pressure cap 7; Under the effect of Returnning spring 8, piston 4 increases sucker 2 inner volume of air oppositely to pedestal 1 slide outside; Pressure reduces, thereby makes atmosphere produce bigger pressure to sucker 2.

The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the utility model.

Claims

1. the sucker-type hook includes pedestal and sucker, and sucker is installed on the pedestal; It is characterized in that: on pedestal, form through hole, be provided with piston in the through hole, be provided with seal ring between plug and the hole wall; Piston is provided with the piston rod that stretches out in the hole; Outer end at piston rod forms pressure cap, is connected to Returnning spring at upper cover of piston rod, and Returnning spring is compressed between pressure cap and the pedestal.
