Abstract

The utility model discloses a sucker, which comprises a rubber main body, a leather ring and a main body. More than one groove is reserved on the suction surface of the rubber main body. The leather ring is arranged on the outer edge of the suction surface of the rubber main body. The utility model also discloses a hook made by the sucker.

Description

A kind of sucker and hook

Technical field

The utility model relates to the daily necessities field, is meant a kind of sucker and hook especially.

Background technique

Mostly vacuum chuck in the market and hook are integrated type vacuum chuck and hook can directly be adsorbed on glass, on the smooth surfaces such as ceramic tile.Its principle is to utilize ambient pressure with chuck surface and need the air between the smooth surface of absorption to extrude, and makes form vacuum between chuck surface and the surface that needs absorption, and external atmosphere pressure just firmly is pressed in sucker on the surface that need adsorb so.But along with the adsorption time of vacuum chuck is more and more longer, can slowly get into air in the sucker, cause existing vacuum chuck in most of the cases all can not be adsorbed on well on the surface that needs absorption, so the heavier article of its unsuitable suspension.

The model utility content

In view of this, the purpose of the utility model is to propose a kind of sucker and hook, and vacuum-adsorption type sucker and hook internal structure that existing technology is made are improved, and its adsorption force is strengthened greatly.

A kind of sucker based on above-mentioned purpose the utility model provides comprises body of rubber, apron and main body, on the adsorption plane of said body of rubber, has more than one groove, and the adsorption plane outer of said body of rubber is provided with said apron; The hook that the utility model provides is then for using the vacuum-adsorption type hook of said sucker structure.

When using said sucker or hook; When sucker or the hook by external force downwards on time, said body of rubber receives the extruding of the reaction force of metope, and its adsorption plane is squeezed; Cause groove on the adsorption plane to receive the external force extruding and close up, air is discharged from through groove simultaneously; Compress the back because the stopping of air to external world of apron arranged, outside air can't be got in the groove again, so, make to form pressure reduction between sucker or hook inside and external atmosphere pressure that sucker or hook then firmly stick on the metope.

Saidly can find out from top; A kind of sucker and hook that the utility model provides; Realized the adsorption type structure of hook through different sucker structures; And the sucker of this design and adsorption type hook, stronger than the adsorptive power of traditional adsorption type hook, make its more common adsorption type hook practical more.

Embodiment

For the purpose, technological scheme and the advantage that make the utility model is clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, to the utility model further explain.

Referring to figs. 1 to Fig. 5, be respectively that the utility model embodiment's whole sectional view, overall structure blown the sectional view of figure, main body 6, the adsorption plane view and the sectional view of body of rubber 4.

Said hook comprises: bolt 1, recessed pad 2, pad 3, body of rubber 4, apron 5, main body 6, hook 7, fixed cover 8, spring 9 and mark nut 10.Said sucker then comprises except that hook 7 and other the whole parts the fixed cover 8.

Said main body 6 comprises: be used for socket fixed cover 8 and hook 7 top 61, be used to place body of rubber 4 first groove 62, be used to place second groove 63, central hole 64 and the bottom 65 of apron 5.

Have groove 41 and center hole 42 thereof on the adsorption plane of said body of rubber 4.

In conjunction with Fig. 1 to Fig. 5, the anabolic process of linking up with among the embodiment is following:

The hole that fixed cover 8 passes hook 7 centers is fixed on hook on the fixed cover 8; Fixed cover 8 is enclosed within the outside at main body 6 tops 61 more then; Body of rubber 4 embeds respectively in first groove 63 and second groove 62 of main body 6 with apron 5, and both end faces are fitted with the internal surface of its corresponding groove respectively; Spring 9 is enclosed within on the mark nut 10; Recessed pad 2 is enclosed within on the bolt 1, again pad 3 is enclosed within on the bolt 1, and fit with recessed pad 2; At last; The combination of bolt 1, recessed pad 2 and pad 3 is passed central hole 64 from the direction of the bottom 65 of main body 6; The combination of spring 9 and mark nut 10 is passed central hole 64 from the direction at main body 6 tops 61, bolt 1 and mark nut 10 are connected together.

When sticking on said hook on the metope,, from right to left hook is pressed with reference to figure 1; Body of rubber 4 receives the extruding of the reaction force of metope; Its adsorption plane is squeezed, causes groove 41 on the adsorption plane to receive the external force extruding and close up, air is discharged from through groove 41 simultaneously; Compress the back because the stopping of air to external world of apron 5 arranged, outside air can't be got in the groove 41 again, so, make to form pressure reduction between hook inside and external atmosphere pressure that hook then firmly sticks on the metope.

Through the adsorption type hook of this particular design, the adsorption force of more general adsorption type hook strengthens greatly, makes its more common hook have practicability more.

Described recessed pad 2 is added between pad 3 and the bolt 1, has played the effect of better airtight air gap.

Because the prolongation of service time can slowly get into air in the body of rubber 4 of sucker or hook, this moment, the adsorption force of sucker or hook can weaken; And body of rubber 4 can flick metope gradually, makes that main body 6 is upspring, and will apply certain elastic force this moment to spring 9; Make spring 9 that mark nut 10 is upspring; Simultaneously, the user will weaken through finding mark nut 10 adsorption force of knowing sucker or hook of being upspring, depresses sucker or hook at this moment once more; Then again fastening sucker or hook lose adsorption force and the situation of landing with regard to sucker or hook can not take place unconsciously again.

It is to be noted the optimal way that the use of recessed pad 2 and spring 9 is just adopted for the reliability that strengthens sucker and hook and practicability, this mode of execution is not unique.

In addition, the socket between the main body 6 of said hook, hook 7 and the fixed cover 8 can adopt the mode of ultrasonic fusing to accomplish, and the mode of execution that the mode of execution of this connection is more general has improved the reliability of connection part.

Referring to Fig. 4, the quantity of the groove 41 among the embodiment on the body of rubber 4 is 6, in the practical design, can design the quantity of groove according to the load-bearing kilogram number that product indicated, such as: also can be more than 3 or 3, promptly 4,5, perhaps 8 etc.

Preferably, when groove 41 evenly distributes, can strengthen the adsorption force of sucker and hook better on body of rubber 4.

It is emphasized that the sucker design of accomplishing through above mode of execution is not limited to be applied on the hook product, also can be applied in the product that other need use sucker, for example metope mirror, wall cabinet etc.

The those of ordinary skill in affiliated field is to be understood that: the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model; Any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
