Abstract

The utility model relates to a suction cup device which comprises a suction cup, a casing and a fastener, wherein a through hole is formed in the center of the casing, a connecting rod is fixedly connected on the back of the suction cup and penetrates the through hole in the center of the casing to be connected with the fastener on the other side of the casing, and a layer of soft rubber cushion is laid between the back of the suction cup and the casing; the suction cup device has strong adsorptive power, and can be adsorbed on various rough or uneven wall surfaces or similar articles.

Description

A kind of disk-sucking device

Technical field

The utility model relates to a kind of disk-sucking device

Background technique

Disk-sucking device is commonly used to object is attached on surface of wall or the analog, this device is the sorption face by sucker and adhere to body of wall or the analog surface closely touches to make between the sucker attachment surface and the back side and produces draught head mainly, and whole disk-sucking device can tightly be adsorbed on body of wall or the analog; Disk-sucking device commonly used at present mainly comprises sucker, housing and fastening piece, wherein offer through hole in the housing central position, sucking disc back side is fixed with a connecting rod, the through hole that this connecting rod passes the housing center is connected with the fastening piece of housing another side, described fastening piece is rotating cam or nut or the like normally, rotating cam and connecting rod flexibly connect, can realize by rotation that connecting rod moves back and forth and reach the purpose that increases the sucker adsorption force, and nut can be realized moving back and forth of connecting rod by rotation equally; But this disk-sucking device is when the surface of body of wall that runs into or analog is smooth inadequately or smooth, sorption face at sucker can not closely contact with body of wall or analog surface, have gas leak phenomenon, the whole device of sucker this moment just can't be adsorbed on this body of wall and analog surface securely.

The model utility content

The purpose of this utility model is to provide a kind of disk-sucking device, even run into absorption surface when more coarse, also can adsorb firmly on this surface.

The utility model is achieved in that

A kind of disk-sucking device, comprise sucker, housing and fastening piece, wherein offer through hole in the housing central position, sucking disc back side is fixed with a connecting rod, the through hole that this connecting rod passes the housing center is connected with the fastening piece of housing another side, it is characterized in that: also be lined with the soft rubber cushion of one deck between described sucking disc back side and the housing.

Described soft rubber cushion can surround the outer rim of sucker, and soft rubber cushion is glued with on the surface of housing.

The utility model is when running into surface irregularity or more coarse metope or analog, soft rubber cushion between sucker and the housing is under the effect of pressure, can play good sealing and deposit work, the adsorption plane of sucker is isolated from the outside, therefore can make disk-sucking device possess better adsorption force.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a perspective exploded view of the present utility model;

Fig. 3 is a perspective exploded view on the other hand of the present utility model.

Embodiment

As Figure 1-3, a kind of disk-sucking device, comprise sucker 1, housing 2 and fastening piece, wherein offer through hole 21 in housing 2 central positions, sucker 1 back side is fixed with a connecting rod 11, and the through hole 21 that this connecting rod 11 passes housing 2 centers is connected with the fastening piece of housing 2 another sides, also is lined with the soft rubber cushion 3 of one deck between described sucker 1 back side and the housing 2, above-mentioned soft rubber cushion 3 can surround the outer rim of sucker 1, and soft rubber cushion 3 is glued with on the surface of housing 2.

The utility model can have very strong adsorptive power at flat more smooth or smooth metope or analog as existing common sucker; Run into metope simultaneously when more coarse or smooth inadequately, utilize the characteristics that soft rubber cushion is yielding in the pressure effect and can closely contact with contact surface, when making the utility model run into coarse or smooth inadequately metope or analog, the adsorption plane of the fine sucker of soft rubber cushion energy is isolated from the outside, make adsorption plane have bigger draught head, thereby disk-sucking device can firmly be adsorbed on these more coarse or smooth inadequately metopes or analog with extraneous.

Claims

1, a kind of disk-sucking device, comprise sucker, housing and fastening piece, wherein offer through hole in the housing central position, sucking disc back side is fixed with a connecting rod, the through hole that this connecting rod passes the housing center is connected with the fastening piece of housing another side, it is characterized in that: also be lined with the soft rubber cushion of one deck between described sucking disc back side and the housing.

2, a kind of disk-sucking device as claimed in claim 1 is characterized in that: described soft rubber cushion can surround the outer rim of sucker, and soft rubber cushion is glued with on the surface of housing.
