Abstract

The utility model discloses a vacuum can for cupping, which comprises a can body, a piston arranged in the can body, a screw fixedly connected with the piston, and a rotary handle connected with the can body and the screw, wherein, the can body is made of apparent material, the rotary handle is provided with a dead hole inside, the dead hole is provided with a screw thread, the screw is connected on the screw thread inside the dead hole in the rotary way, the rotary handle is provided with a riser vent which is communicated with the inside and the outside of the dead hole, and the upper end part of the rotary handle is provided with a head part the cross section of which is a crisscross. The vacuum can for cupping with vacuum structure is more labor-saving when in use, is convenient to obverse the change of the pulling-up position in the can body, and the screw is contained in the rotary handle, not only the appearance is beautiful, but also the screw thread on the screw cannot hurt the hand.

Description

A kind of vacuum cupping

Technical field

This utility model relates to a kind of physical therapy apparatus, is specifically related to a kind of vacuum cupping.

Background technology

At present, the piston type vacuum cupping of selling on the market, its basic structure is formed and is all comprised tank body, piston, screw rod and swing handle.Tank body is opaque, can't observe jar variation of interior skin histology; Swing handle is thin plate-like, and screw rod is exposed during use, and is not only not attractive in appearance, and screw thread is also easily hindered hands; When the cup of said structure used, because the effect of negative pressure, swing handle was pressed on the tank body, and the air on piston top is difficult for discharging, and relatively required great effort during the rotation swing handle.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of variation that both can conveniently observe jar interior skin histology is provided, again can be laborsaving, and also can contain screw rod and in swing handle, make screw thread be difficult for hindering the vacuum cupping of hands.

In order to solve the problems of the technologies described above, this utility model provides a kind of vacuum cupping of following structure, comprise tank body, be positioned at a jar intravital piston, with the affixed screw rod of piston and be connected on the tank body and the swing handle that is connected with screw rod, its construction features is: described tank body is made with transparent material, be provided with blind hole in the swing handle, be provided with screw thread in the blind hole, screw rod is screwed on the interior screw thread of blind hole, and swing handle is provided with and is communicated with inner with the outside air-vent of blind hole.

The vacuum cupping of said structure during use, is pressed on the position that needs physical therapy to a jar mouth, and the rotation swing handle moves up piston, and this position is pulled up under the effect of negative pressure, thereby reaches the purpose of physical therapy.Because being provided with transparent material is made, screw rod is positioned at swing handle blind hole, swing handle, tank body is communicated with inner with the outside air-vent of blind hole, therefore can conveniently observe the variation that is pulled up the position in the jar, rotation can be laborsaving during swing handle, also can contain screw rod to make screw thread be difficult for hindering hands in swing handle.

For the ease of the clamping swing handle, convenient rotation swing handle, swing handle is provided with the head that cross section is " ten " font.
