Abstract

A suction cup is made of plastic and shaped like a disk, and a valve is arranged in an upward central hole of the bottom of the disk. During use, the suction cup is aimed at a wall surface and forcibly pressed towards the wall surface, so that the air in the suction cup can be squeezed out, and meanwhile, a valve disc arranged in the suction cup is pushed upwards to tightly press a valve seat, so that an air channel can be closed. The suction cup is vacuumized and tightly attached on the wall surface under the pressure of atmosphere; when the suction cup needs to be taken down, a valve-rod push button which extends out of the bottom of the disk is pushed, as a result, the valve disc leaves the valve seat, the air enters the suction cup, so that the suction cup can be easily released, and consequently, the suction cup can be conveniently reused.

Description

A kind of sucker

Technical field

The utility model relates to a kind of absorption utensil, specifically a kind of sucker that utilizes the suction that vacuum produces.

Background technique

Now, various suckers are a lot, and its adsorption force is big more, and the longer the better for adsorption time, in daily use, sometimes used sucker needs to use repeatedly, and is inconvenient in the time of still will taking off, big more difficult more the taking off of suction do not done a good job and also can be damaged the bottom plane, even sucker is damaged.

The model utility content

Remove the problem of getting off in order to solve the sucker difficulty from the wall of absorption, the utility model provides a kind of sucker, and this sucker is provided with the venting valve on carrying handle, can easily sucker be taken off from suction face.

The utility model solves the technical measures that its technical problem takes, sucker is made the dish shape with plastic cement, at the bottom of the dish up, valve rod hole is opened at the center, the lower end in hole, just true chamber one side chamfer machining becomes valve seat in the dish bottom surface, valve rod passes from the hole, valve rod slides up and down at Kong Zhongneng, the valve rod lower end is made taper and is cooperated energy occluded air passage with valve seat, opens air hole on the hole wall on valve seat top, and the vacuum chamber under the situation that cone valve is opened in the sucker communicates with atmosphere by air hole, mushroom handle handle is made with the button that is threaded, the outer wall of valve rod hole in the upper end of valve rod.During use sucker tipped upside down on and form an enclosed vacuum chamber on the better plane of surface finishment, firmly press sucker simultaneously, make the discharge of the air in the vacuum chamber in its sucker, simultaneously, valve rod upwards pushes away the taper valve disc contacts the sealing air hole with valve seat passage when sucker is pressed, make vacuum chamber and atmospheric isolation in the sucker, after the air emptying in the vacuum chamber, utilize the pressure of atmosphere that sucker tightly is attached on the plane sucker is fixed.If will using repeatedly, sucker needs to take off from the plane, by the button on the lower valve rod, away from valve seat, atmosphere enters from air hole in true this cavity when handle fertilizer upwards can be carried, make in the vacuum chamber and the atmospheric pressure balance, thereby reach the purpose that sucker is taken off from the plane easily.

The utility model beneficial effect is that sucker takes off from wall easily, reuses to sucker and provides convenience, and is simple in structure.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of sucker.

Among the figure, 1, button, 2, the handle handle, 3, air hole, 4, valve seat, 5, sucker, 6, vacuum chamber, 7, the taper valve disc, 8, valve rod, 9, valve rod hole.

Embodiment

In Fig. 1, sucker 5 usefulness plastic cement are made the dish shape, and the dish face forms vacuum chamber 6, opens valve rod hole 9 at the bottom of the dish up, and the lower end chamfer machining in hole becomes valve seat 4, and hole wall is opened air hole 3 above valve seat 4.Valve rod 8 passes valve rod hole, and taper valve disc 7 is processed in its lower end, when valve rod upwards pushes away, valve disc can be pressed on the valve seat, close the air passageways of air hole 3, the outer wall of valve rod hole is processed into the handle of mushroom 2, and valve rod hole is stretched out with the button 1 that is threaded in the upper end of valve rod.

Claims

1, a kind of sucker is made the dish shape with plastic cement, at the bottom of the dish up the center open valve rod hole, the lower end chamfer machining in hole becomes valve seat, it is characterized in that: valve rod passes from valve rod hole, the taper valve disc is made in the lower end, valve rod hole is stretched out with the button that is threaded in the upper end.

2, a kind of sucker according to claim 1 is characterized in that: open air hole on hole wall above the valve seat.

3, a kind of sucker according to claim 1 is characterized in that: the outer wall of valve rod hole is processed into mushroom handle handle.
