Abstract
The utility model discloses a powerful suction cup, comprising a suction sheet, wherein a screw-threaded core bar is fixedly arranged in the central part of the suction sheet, a circular middle cover and a spring are sleeved on the screw-threaded core bar, the spring is arranged between the middle cover and the suction sheet, an annular groove is disposed around the screw-threaded core bar on the middle cover, and a U-shaped jump ring is arranged inside the groove. The suction cup further comprises a top cover with a screwed hole by which the screw-threaded core bar is in threaded connection with the top cover. The powerful suction cup is insensitive to the loosening of the screw thread, and has better durability.
Description
Technical field
The utility model relates to a kind of powerful electromagnetic chuck.
Background technique
Traditional sucker all has the suction sheet of a softness; After being pressed on the suction sheet on the smooth body surface; Inhale sheet resilience under the effect of self elastic force; Thereby, utilize the pressure of atmosphere to make sucker to be adsorbed on the body surface inhaling very little vacuum area of generation between sheet and the body surface.Inhale the flexible restriction of sheet but such sucker receives, enough adsorption forcies can not be provided.In order to let sucker that enough adsorption forcies are arranged; People have set up screw-threaded coupling device again on the basis of inhaling sheet; This device is on the suction sheet, a screw thread core bar to be set, and a sheathed middle cover is pressing middle cover to be connected on the screw thread core bar with a blind nut again on the screw thread core bar.After inhaling sheet and being pressed on body surface, the blind nut of screwing, the compacting middle cover with inhale sheet, just make and inhale the pressure that sheet not only receives atmosphere that also receive the impacting force of blind nut, so the adsorption force of sucker has just had significantly and improves.
But the sucker of this screw fastening compact form is an imperfect technological scheme of endurance; Reason be to inhale on the sheet screw threads for fastening can produce through the carrying of certain hour, after expanding with heat and contract with cold certain loosening; And the screw threads for fastening mode is to small loosening very sensitive; Screw-thread fit is loosening a little, just has tangible coupling mechanism force to descend.Therefore need to occur a kind of powerful electromagnetic chuck that enough endurance is arranged.
The model utility content
The utility model is in order to overcome above-mentioned defective of the prior art, to provide a kind of double thread to become flexible insensitive powerful electromagnetic chuck, having better endurance.
For realizing above-mentioned purpose, the openly following technological scheme of the utility model:
A kind of powerful electromagnetic chuck; Comprise that is inhaled a sheet; The center of this suction sheet has set firmly a screw thread core bar, on this screw thread core bar, is arranged with middle cover and spring of a circle, and said spring is pressed between said middle cover and the said suction sheet; Cover in said around said screw thread core bar and be provided with a circle groove, be provided with a U type jump ring in the groove; Also comprise a top cover, be used to be threaded in said screw thread core bar with tapped hole.
Further, the physical dimension of the outer rim of said middle cover and said suction sheet is identical or be slightly larger than the physical dimension of said suction sheet.
Further, the tapped hole on the said top cover is a blind hole.
Further, groove one side that covers in said has horizontally extending breach.
Compared with prior art, the utlity model has following beneficial effect:
1, spring can tightly withstand being threaded between top cover and the screw thread core bar at the elastic force that is compressed the back generation; Even receiving long carrying and expand with heat and contract with cold, can not become flexible by sucker yet; Screw threads for fastening power is able to permanent maintenance; Thereby have better endurance, spring can also make sucker have bigger load-carrying ability simultaneously.
2, jump ring can be lived the fixed-site of screw thread core bar and spring, makes the structure of whole sucker more stable, is not easy recurring structure distortion when carrying.
3, the outer rim of middle cover equals or is slightly larger than the outer rim of inhaling sheet, thereby can protect soft suction sheet, prevents to inhale sheet and deforms because of the collision that receives the front or illumination or harden.
4, top cover not only can provide fastening force, also has decorating action, especially has the top cover of blind hole, and is more convenient as trim.
Description of drawings
Fig. 1 is the main sectional view of the utility model;
Fig. 2 is the explosive view of the utility model.
In conjunction with the accompanying drawing following reference character of mark above that:
The 1-top cover, the 2-jump ring, the 3-middle cover, the 4-spring, 5-inhales sheet, 51-screw thread core bar.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
A kind of powerful electromagnetic chuck, as illustrated in fig. 1 and 2, comprise that is inhaled a sheet 5; The center of this suction sheet 5 has set firmly a screw thread core bar 51, on this screw thread core bar 51, is arranged with middle cover 3 and spring 4 of a circle, and said spring 4 is pressed between said middle cover 3 and the said suction sheet 5; Be provided with a circle groove around said screw thread core bar 51 on the said middle cover 3; Be provided with a U type jump ring 2 in the groove, jump ring 2 can block screw thread core bar 51, thereby the fixed-site of screw thread core bar 51 and spring 4 is got off; Pressure can evenly be released in inhale on the sheet 5, can prevent to inhale sheet 5 and occur gliding or dropping because of discontinuity.Groove one side on the said middle cover 3 has horizontally extending breach, is used for when installation and removal jump ring 2, providing convenience, in order to avoid jump ring is surrounded and can't take out by the perisporium of groove.The physical dimension of the outer rim of said middle cover 3 and said suction sheet 5 is identical or be slightly larger than the physical dimension of said suction sheet 5, so that protection to be provided.This powerful electromagnetic chuck also comprises a top cover 1 with tapped blind hole, is used to be threaded in said screw thread core bar.
During use, whole powerful electromagnetic chuck is pressed on the body surface, and then is tightened on top cover 1 on the screw thread core bar 51 and gets final product.
More than the disclosed more excellent specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
