Abstract
The utility model provides a rubber plunger, belongs to domestic instrument field, constitutes its characterized in that by interior hemisphere, connecting block, outer hemisphere, cylinder body, piston, groove, slider, buting iron and bracelet: interior hemisphere links together through connecting block and outer hemisphere, and the cylinder body is being connected to the upper end of interior hemisphere to the same with the hole in the cylinder body, the piston is installed in the cylinder body, can reciprocate, and the outside of cylinder body is slotted, and the slider can reciprocate at the inslot in being embedded into the groove in the cylinder body outside, the outside of cylinder body, and there is the buting iron on the upper portion in groove, can regard as the top dead center of slider motion, the upper portion and the bracelet fixed connection of slider. This rubber plunger is showing the negative pressure intensity that has strengthened the production under the circumstances that does not increase the volume.
Description
Technical field
The utility model relates to a seed coat plunger, specifically have employed a kind of a kind of instrument significantly expanding the negative pressure produced when skin plunger is applied of the compositions such as interior hemisphere, outer hemisphere and piston, belongs to a staple field.
Background technology
The shortcomings such as skin plunger is a kind of conventional household appliance, and current skin plunger has that structure is simple, and application life is short, and the negative pressure of generation is little, use inconvenience.
Summary of the invention
For above-mentioned deficiency, the utility model provides a seed coat plunger.
The utility model is achieved through the following technical solutions: a seed coat plunger, by interior hemisphere, contiguous block, outer hemisphere, cylinder body, piston, groove, slide block, buting iron and bracelet form, it is characterized in that: interior hemisphere is linked together by contiguous block and outer hemisphere, the upper end of interior hemisphere is connected to cylinder body, and it is identical with the hole in cylinder body, piston is arranged in cylinder body, can move up and down, there is groove in the outside of cylinder body, slide block is embedded in the groove outside cylinder body, can move up and down in groove, the outside of cylinder body, buting iron is arranged at the top of groove, can be used as the top dead centre of slide block movement, the top of slide block is fixedly connected with bracelet.
The material that described interior hemisphere is used is soft, can under the negative pressure of interior hemisphere with lower contact surface good combination, formed sealing space, the soffit of interior hemisphere will grow the soffit of outer hemisphere.
Described contiguous block is discrete, is distributed in the centre of interior hemisphere and outer hemisphere, and upper space and the lower space of contiguous block have many parts that is connected.
Described outer hemisphere material therefor is that internally hemisphere is harder mutually, and still deformable under external force, can play a supportive role to whole interior hemisphere and outer hemisphere.
The usefulness of this utility model is, the structure of hemisphere and the two-layer hemisphere of outer hemisphere in adopting, particularly, hemisphere adopts soft material, and outer hemisphere adopts hard material, it easily can seal with outer contacting face below and combines under negative pressure to make interior hemisphere, and outer hemisphere can play a supportive role; Adopt the fit system of cylinder body and piston, negative pressure during application can be enlarged markedly.On whole structure, the skin plunger of this structure has when volume does not increase, and has increased considerably suction strength.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1, interior hemisphere, 2, contiguous block, 3, outer hemisphere, 4, cylinder body, 5, piston, 6, groove, 7, slide block, 8, buting iron, 9, bracelet.
Detailed description of the invention
One seed coat plunger, by interior hemisphere 1, contiguous block 2, outer hemisphere 3, cylinder body 4, piston 5, groove 6, slide block 7, buting iron 8 and bracelet 9 form, it is characterized in that: interior hemisphere 1 is linked together by contiguous block 2 and outer hemisphere 3, the upper end of interior hemisphere 1 is connected to cylinder body 4, and it is identical with the hole in cylinder body 4, piston 5 is arranged in cylinder body 4, can move up and down, there is groove 6 in the outside of cylinder body 4, slide block 7 is embedded in the groove 6 outside cylinder body 4, can move up and down in groove 6, the outside of cylinder body 4, buting iron 8 is arranged at the top of groove 6, can be used as the top dead centre that slide block 7 moves, the top of slide block 7 is fixedly connected with bracelet 9.
The material that described interior hemisphere 1 is used is soft, can under the negative pressure of interior hemisphere 1 with lower contact surface good combination, formed sealing space, the soffit of interior hemisphere 1 will grow the soffit of outer hemisphere 3.
Described contiguous block 2 is discrete, is distributed in the centre of interior hemisphere 1 and outer hemisphere 3, and upper space and the lower space of contiguous block 2 have many parts that is connected.
Described outer hemisphere 3 material therefor is that internally hemisphere 1 is harder mutually, still deformable under external force, can play a supportive role with outer hemisphere 3 to whole interior hemisphere 1.
During this tool applications, user of service holds bracelet 9, firmly press down, piston 5 is moved down, until bracelet 9 contacts with cylinder body 4, and then presses down, until outer hemisphere 3 is out of shape, then handle ring 9 is gone up, until slide block 7 runs into buting iron 8 and outer hemisphere 3 leaves its lower contact surface, i.e. an one complete course of work.
For the ordinary skill in the art, according to instruction of the present invention, when not departing from principle of the present invention and spirit, the change carried out embodiment, amendment, replacement and modification still fall within protection scope of the present invention.
Claims (4)
