Abstract

The utility model relates to a suction cup, which belongs to medical healthcare apparatuses. The suction cup disclosed by the utility model comprises a suction cup body, a handle, a piston rod and a piston, wherein the piston is placed at the lower end of the piston rod; the lower segment of the handle is emptily sleeved and installed on an installing hole at the top of the suction cup body, and the handle can freely rotate; the handle is matched and connected with an external thread on the piston rod through a threaded hole at the center; a sealing ring is arranged between the edge of the piston and the inner wall of the suction cup body; and a vent hole is arranged at the upper part of the suction cup body. After the structure is adopted, the piston rod and the piston can ascend and descend in the suction cup body by rotating the handle which is emptily sleeved on the suction cup body, so that a negative pressure is generated at the lower part of an inner cavity of the suction cup body, an adsorbing action can be realized without ignition, the purpose of medical healthcare is achieved, and therefore the phenomenon of burning or scalding the skin in the use process of a traditional suction cup is avoided, and the suction cup is safe and reliable to use; and because of the arranged vent hole, the air at the upper part of the inner cavity of the suction cup body can be smoothly discharged, so that the suction cup is reliable to operate, and clamping stagnation is not easy to occur.

Description

Suction cup

Technical field

This utility model relates to a kind of suction cup, belongs to medical health apparatus.

Background technology

Cup is a kind of traditional medical health method, and traditional suction cup mainly is a kind of cupping jar, when adopting traditional cupping jar to carry out cup, in cupping jar, light a fire, air in the cupping jar meets thermal expansion this moment because the air pressure in the jar is lower than extraneous air pressure, cupping jar is held on the human body, causes local capillary injection when pulling up cupping jar, and blood circulation promoting reaches the health care purpose.This method simple possible, effect significantly is widely used, but owing to realize negative pressure by a jar interior igniting, in the operation engineering, tend to inconvenient operation, the dynamics of pulling out suction also because that the duration and degree of heating is grasped is not accurate enough, wayward, is easy to burn or scalded skin.At present existing a kind of piston type suction cup though solved burn or scald problem, has also overcome the suction degree problem of pulling out to a certain extent, since the design more complicated, the cost height, and the passage setting also rationally still can not be satisfied people's needs inadequately.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of not only simple in structure, easy to operate, safe and reliable but also can effectively control the suction cup of negative pressure.

In order to solve the problems of the technologies described above the piston that suction cup of the present utility model includes tank body, handle, piston rod and places piston-rod lower end; Empty the overlapping on the installing hole that is installed in the tank body top of handle hypomere also can rotate freely; Handle is connected by the screwed hole at center and the external screw thread on the piston rod; Be provided with sealing ring between piston edge and the inner tank wall; The top of tank body is provided with passage.

Described handle hypomere has one section undergauge section of passing tank body top installing hole, has a collar to be enclosed within the undergauge section in the tank body handle is carried out axial limiting, and collar lower end is spacing by the baffle ring 8 that is installed in handle, at its lower end.

After adopting such structure, be enclosed within handle on the tank body by rotating sky, can make the lifting in tank body of piston rod and piston, the negative pressure that the tank inner chamber bottom is produced, need not light a fire, just can realize the effect of adsorbing, reach the purpose of health care, thereby avoided traditional cupping jar in use to burn or the phenomenon of scalded skin, safe and reliable; Because the passage that is provided with can make the air on tank inner chamber top discharge swimmingly, make that operation is reliable, be difficult for taking place clamping stagnation.

Description of drawings

Fig. 1 is the structural representation of this utility model suction cup.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model suction cup is described in further details.

As shown in the figure, this suction cup piston 4 of including tank body 1, handle 2, piston rod 3 and placing piston-rod lower end; Empty the overlapping on the installing hole 5 that is installed in tank body 1 top of handle hypomere also can rotate freely; Handle is connected by the screwed hole at center and the external screw thread on the piston rod 3; Be provided with sealing ring 6 between piston 3 edges and tank body 1 inwall; The top of tank body is provided with passage 9.

The handle hypomere has one section undergauge section of passing tank body top installing hole 5, has a collar 7 to be enclosed within the undergauge section in the tank body handle is carried out axial limiting, and the collar 7 lower ends are spacing by the baffle ring 8 that is installed in handle, at its lower end, realizes that the sky cover at handle and tank body top is installed.

During use, tank body 1 lower end can be withheld on human body, regulating handle 2 then, regulate with the rotation that cooperates of tank body 1 interior screwed piston rod by handle 2, the pulling piston moves upward, make the volume of tank body lower cavity increase air pressure and descend, and produce negative pressure and can be adsorbed on the human body simultaneously, thereby realize the purpose of treatment and health.
