Abstract
The utility model relates to a sucking disc, which mainly solves the problem that the using performance of the current sucking discs is affected caused by reduction of the adsorptive capacity due to poor sealing performance of the current sucking discs. The sucking disc comprises a sucking disc body, a sucking piece and an operating part. The sucking piece is attached to the front end of the sucking disc. The operating part is connected with the sucking piece and shifts axially to form the center of the sucking piece which recesses inward to form a negative pressure. A bulge loop is arranged on the end face of the sucking piece. A step is arranged on the outer edge of the sucking disc body. The bulge ring is locked with the step to form radial limited match. As the sucking piece on the sucking disc and the sucking disc body are radially limited, the sucking piece at negative pressure is prevented from recessing to the center to lead to imprecise attachment of the rim of the sucking piece and the sucking disc body so that the sealing effect of the sucking piece and the sucking disc is enhanced, the adsorbing capacity of the sucking disc is improved, and the service life of the product is effectively prolonged.
Description
Technical field
The utility model relates to a kind of vacuum suction member, is meant a kind of sucker especially.
Background technique
The sucker application is more extensive, and its effect through negative pressure of vacuum realizes being adsorbed on body surface, easy to operate, use simple.At present, the suction sheet on the sucker and the surface of sucker body directly fit, through the recessed inward formation negative cavity in the center of drawing attracting sheet; Thereby realize being adsorbed on object surfaces inhaling sheet; Inhale sheet toward in recessed in owing to the periphery of inhaling sheet is carried out radially spacing, inhaling sheet will the contraction toward the center; Inhale sheet and the poorly sealed close problem of sucker body thereby cause, thereby cause the adsorptive power of sucker to descend.In addition, the suction sheet of sucker does not carry out circumferentially spacing, in the using process, rotates easily, causes the poor stability of its use.
The model utility content
In order to overcome deficiency and the defective in the background technique, the utility model provides a kind of sucker, has solved existing sucker and has existed sealing poor, causes adsorptive power to reduce, thereby has influenced the problem of sucker usability.But also solved the shortcoming that there is the poor stability when using in existing sucker.
The technological scheme of the utility model is: a kind of sucker; Comprise the sucker body, inhale sheet and functional unit; Said suction sheet fits in the front end of sucker body, and said functional unit is connected with the suction sheet and its axial displacement constitutes the inside recessed formation negative pressure in center of inhaling sheet, and the end face of said suction sheet is provided with bulge loop; The outer edge of said sucker body is provided with step, and said bulge loop fastens with step and constitutes radially spacing the cooperation.
The end face of said sucker body is provided with some circumferential grooves distributed, and the corresponding section is provided with to fasten with said groove and constitutes circumferentially spacing boss on the said suction sheet.
Said boss and groove circumferentially are evenly distributed.
Said functional unit is a knob; The inwall of said knob is provided with some Ka Tai; Said sucker body is provided with at least two helicoids; Said each adjacent card platform is positioned on the same helicoid, and the end of said each helicoid is provided with limited post, and said knob is provided with the link that is not connected with the sucker body.
Said link is a barb, and the intermediate portion of said suction sheet is provided with the cylindrical body that one connects, and said cylindrical body is provided with the annular convex rib that blocks mutually with said barb.
Compared with prior art; The utlity model has following beneficial effect: owing to adopted radially spacing between suction sheet on this sucker and the sucker body; Prevent to inhale sheet and when negative pressure, cause the imprecision of fitting between its periphery and the sucker body to the center is recessed; Thereby make the sealing effect of inhaling sheet and sucker body strengthen, improve the adsorptive power of sucker, effectively prolonged the working life of product.
Description of drawings

Among the figure, sucker body 1 is inhaled sheet 2, functional unit 3, bulge loop 4, step 5, groove 6, boss 7, card platform 8, helicoid 9, limited post 10, barb 11, cylindrical body 12, annular convex rib 13.
Embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure; This sucker comprises sucker body 1, inhales sheet 2 and functional unit 3, and said suction sheet 2 fits in the front end of sucker body 1; Said functional unit 3 is connected with suction sheet 2 and its axial displacement constitutes the inside recessed formation negative pressure in center of inhaling sheet 2; The end face of said suction sheet 2 is provided with bulge loop 4, and the outer edge of said sucker body 1 is provided with step 5, and said bulge loop 4 fastens with step 5 and constitutes radially spacing the cooperation.Owing to adopted radially spacing between suction sheet 2 on this sucker and the sucker body 1; Prevent to inhale sheet 2 and when negative pressure, cause the imprecision of fitting between its periphery and the sucker body 1 to the center is recessed; Thereby make the sealing effect of inhaling sheet 2 and sucker body 1 strengthen; Improve the adsorptive power of sucker, effectively prolonged the working life of product.
In the utility model, the end face of said sucker body 1 is provided with some circumferential grooves distributed 6, and the corresponding section is provided with to fasten with said groove 6 and constitutes circumferentially spacing boss 7 on the said suction sheet 2, and said boss 7 circumferentially is evenly distributed with groove 6.To block realization mutually circumferentially spacing through inhaling boss 7 and groove 6 on the sucker body 1 on the sheet 2, thereby make the stability of sucker be improved.
In the utility model; Said functional unit 3 is a knob; The inwall of said knob is provided with some card platforms 8, and said sucker body 1 is provided with at least two helicoids 9, and said each adjacent card platform 8 is positioned on the same helicoid 9; And the end of said each helicoid 9 is provided with limited post 10, and said knob is provided with the link that is connected with sucker body 1.When sucker was adsorbed on wall surface, through card platform 8 matching relationships on 9 structures of the helicoid on the sucker body 1 and the rotation set, when the rotation rotation set, rotation set moved axially and draws attracting sheet 2 inside recessed realization negative pressure effects.
In the utility model, said link is a barb 11, and the intermediate portion of said suction sheet 2 is provided with the cylindrical body 12 that one connects, and said cylindrical body 12 is provided with the annular convex rib 13 that blocks mutually with said barb 11.Block realization mutually through barb and annular convex rib 13 and connect, the soundness of connection is good, and stability is high, and usability is good.
