Embodiment

To shown in Figure 5, sucker comprises softness, resilient plastic cement sucker 201, circular arcuation thin plate 301 and functional part 401 as Fig. 3, and thin plate 301 can be an iron plate, also can be plastic board or other sheet of material.Sucker 201 utilize on its cylindrical vent 204 outer walls and middle boss 210 outer walls on twice groove 202,203 be flush-mounted in two circular holes 302,303 on the thin plate 301, make sucker 201 be fixed on the below of thin plate 301.The different available welding of functional part 401 (as shown in Figure 1 and Figure 2) of all kinds of application targets, be spirally connected or alternate manner is fixed on thin plate 301 tops, for use.When pressing sucker, sucker 201 is adsorbed on the smooth object surface, simultaneously since itself and thin plate 301 be mutually permanently connected, be close to the smooth object surface so drive thin plate 301, cause the circumferential edges of thin plate 301 to be pressed on sucker 201 and the smooth object surface, thin plate 301 has played the effect of base, does not so just make functional part 401 steadily, do not rock.Sucker 201 is provided with cylinder-shaped valve rod 501 that a cylindrical vent 204, one bottoms are taper and passes cylindrical vent 204 backs and are spirally connected with the button 601 that is positioned at thin plate 301 outsides and are fixed together.One spring 701 be inserted in cylinder-shaped valve rod 501 and place button 601 and sucker 201 between.Spring 701 1 ends terminate on the step 205 of ventilation 204 tops, and the other end acts on button 601, and button 601 is promoted laterally.Because button 601 is affixed with valve rod 501, so spring 701 outwards promotes valve rod 501 simultaneously.There is one section circular cone 502 valve rod 501 lower ends, and it has been pressed on the opening sharp edge 206 of vent 204 tightly.Because 201 employings of plastic cement sucker are soft, the bullet material, external sealed is isolated in causing, and air can not pass through.Circular cone 502 can compensate the size error of the opening sharp edge 206 that causes owing to accuracy of manufacturing automatically.Because vent valve mechanism seals under normal conditions, so the adsorptive process of sucker and existing sucker are just the same, gently once by can firmly being adsorbed on the smooth object surface.As this sucker is unclamped from being adsorbed the surface, need only a have gentle hands press button 601, just carrying functional part 401, another have gentle hands can easily realize.When pressing the button 601, button 601 related valve rods 501 move downward, and cause the conical surface 502 of valve rod 501 belows and the opening sharp edge 206 of sucker 201 to become open state from original sealing state.This moment, originally be blocked in the vent 207,208 of sucker 201 air outside by vent valve through reservation on the gap of button 601,

valve rod

501 and 201 of suckers, the sucker 201, and the valve passage that be opened this moment charges into sucker 201 inside rapidly, moment makes sucker 201 internal and external pressure balances, and at this moment whole sucker is just mentioned by the have gentle hands pine of holding functional part 401.

The sucker shown in Figure 6 and the structure of aforementioned sucker are basic identical, and just the structure of vent valve is slightly different.Draw-ring type vent valve in this example comprises that the cylindrical vent 204 of the step type that is opened on the sucker 201, draw ring 505 and head are the cylinder-shaped valve rod 501 of taper, draw ring 505 is fixed together with the head circular cone 502 of valve rod 501, valve rod 501 penetrates in the vent 204, put a spring 701 its tail ends of back on the valve rod 501 and fix a stop block 801 with screw 503, the two ends of spring 701 act on respectively on the step 205 and stop block 801 of vent 204.If want sucker when unclamp on the surface of adsorbing, only need to spur gently outward draw ring 505, related valve rod 501 outward directions motion causes the conical surface 502 of valve rod 501 heads and the outer wall mouth 209 of sucker 201 upper vent holes 204 to become open state from original sealing state.This moment, originally be blocked in sucker 201 air outside by vent valve and charge into sucker 201 inside rapidly through the gap of 201 of valve rod 501 and suckers and the valve passage that has been opened at this moment, moment makes sucker 201 internal and external pressure balances, and at this moment whole sucker just unclamps from the smooth object surface like a cork and removes.Sucker one unclamps, and can loosen draw ring 505.At this moment, under the restoring force effect of spring 701, the conical surface of valve rod 501 heads again with outer wall mouth 209 airtight combinations of vent 204 so that sucker can be adsorbed on the smooth surface of object.
