Abstract

The utility model discloses a structure of pulling and pushing type drew pot. The drew pot comprises a pot body, and a piston fitted with the pot body. The piston is a push-and-pull rod with a tooth. One end of the push-and-pull rod is connected with two rigidity supports. The place between these two rigidity supports is equipped with a flexible slice whose circumference is fixed with the inwall of the pot. The top of the pot body is connected with a pawl which is fitted with the tooth on the push-and-pull rod. The major advantages of the utility model are that the sucking and pulling force is strong and controllable, the structure is simple; it is easy in use, and the safety is reliable.

Description

Pulling and pushing type drew pot

This utility model belongs to the traditional medical apparatus, says with having, relates to a kind of structure of plug-type cup.

Cup is one of Chinese traditional treatment, health care means, and is with a long history, and traditional utensil is a tank body, during use, with air in the firing post, rapidly the jar mouth is buckled on affected part or the acupuncture point, because shrinking, a jar interior gas cooled produces negative pressure, and tank body is pulled on affected part or acupuncture point, reach the purpose of treatment and health care, conventional appliances is had relatively high expectations to the operation technique of user, otherwise the meeting skin ambustion, and can not control the power of pulling, particularly be not easy to oneself's operation.Some modified model cups have appearred in recent years, operation is further simplified, and patent 90223360,2 discloses a kind of " piston type suction cup ", and it mainly is made of tank body and the piston that cooperates with tank body, the main deficiency of this cup is: sealing is poor, and the power that pulls is little and can not control.

Task of the present utility model is exactly in order to overcome the deficiencies in the prior art, and proposes a kind of good airproof performance, pulls the structure of the novel cup of power adjustable size joint.

In order to realize above-mentioned task, the technical scheme that adopts is: the piston that cooperates with tank body 1 is a push-pull bar 2 that latch is arranged vertically, one termination of push-pull bar has last rigidity holder 2 and the following rigidity holder 3 of diameter less than tank body, accompanies periphery and the affixed flexible sheets 4 of inner tank wall between two rigidity holders; Have one with push-pull bar on the ratchet 5 that cooperates of latch be connected with tank body top hinge.

The utility model has the advantages that: the power that pulls is big, and may command; Simple in structure, carry, easy to use; No pyrotechnics pollutes, and is safe and reliable.

The drawing of this utility model accompanying drawing is described as follows:

Fig. 1 is the structural representation of this utility model embodiment.

The utility model is described in further detail below in conjunction with drawings and Examples:

Embodiment of the present utility model as shown in Figure 1, its last rigidity holder 2 cross section vertically be "

" shape; Following rigidity holder 3 cross section vertically be "

" shape.

Tank body 1 of the present utility model also can be divided into upper and lower two parts, and top is divided into a top a housing that is slightly larger than the hole of push-pull bar diameter, and upper and lower two parts of tank body are threaded or are bonding.

The bundle pawl 5 of this utility model embodiment is a drift angle less than 30 ° triangle, on the base at place, a nearly base angle outstanding one "

" angle, at nearly another place, base angle hinge shaft hole is arranged; Nearly drift angle place at ratchet is connected to the back-moving spring 6 that is connected with the tank body top.

Claims

1, a kind of plug-type cup, constitute by tank body and the piston that cooperates with tank body, it is characterized in that: piston is a push-pull bar that latch is arranged vertically, and a termination of push-pull bar has two the rigidity holders of diameter less than tank diameter, accompanies periphery and the affixed flexible sheets of inner tank wall between the two rigidity holders; Have one with push-pull bar on the ratchet that cooperates of latch be connected with tank body top hinge.

2, according to the described plug-type cup of claim 1, it is characterized in that: following rigidity holder cross section vertically for "

" shape; Last rigidity holder cross section vertically be "

" shape.

3, according to claim 1 or 2 described plug-type cups, it is characterized in that: tank body is divided into two parts up and down, and top is divided into a top a housing that is slightly larger than the hole of push-pull bar diameter, and upper and lower two parts of tank body are threaded or are bonding.

4, according to claim 1,2 or 3 described plug-type cups, it is characterized in that: ratchet is a drift angle less than 30 ° triangle, on the base at place, a nearly base angle outstanding one "

" angle, at nearly another place, base angle hinge shaft hole is arranged; Nearly drift angle place at ratchet is connected to the back-moving spring that is connected with the tank body top.
