Description

Improved structure of massage gun

This creation is related to physiotherapy supplies, especially regarding the improved construction of a massage gun.

In order to provide a massage similar to massage, kneading or beating, the power provided by the power source is outputted as a predetermined trajectory by appropriate transmission technology, thereby providing appropriate massage action to the human body to achieve physical therapy. The effect is a well-known technique commonly used.

Among them, the electromagnetic component is used as the power source, and the linear reciprocating motion provided by the magnet element is used to provide the massage gun technology for pressing the local part of the human body. The specific example is as disclosed in the new patent case No. M446632 of China. However, the specific technique of synchronizing the massage head and the output shaft by applying a massage action to the human body lacks a moderate cushioning and limits the intensity of the massage action, causing the user to be overly mechanized and exerting difficulty. The degree of comfort.

Furthermore, in the case of the new patent No. M493379 in China, it is further disclosed that the rotary motion outputted by the rotary motor is converted into a linear reciprocating motion by a suitable transmission mechanism, and the output shaft and the massage member are separated from each other. The reciprocating linear motion causes intermittent hammering action on the massage component, thereby applying pressure to a local part of the human body. The massage effect is the massage action performed by the intermittent hammering on the human body. Compared with the synchronous movement disclosed in the new patent No. 632, it is closer to the massage action of hammering and pressing. To achieve better massage effect, however, because the composition of the '379 new patents is too complicated, in addition to increasing the volume and cost, the increase in weight also causes the user to bear the burden, which may cause occupational injuries. After that, there is a need to improve it.

Therefore, the main purpose of this creation is to provide an improved structure of a massage gun which can exert a better massage effect on the human body.

The reason is that, in order to achieve the above object, the improved structure of the massage gun provided by the present invention includes a guide seat having a portion, a shaft hole extending in a straight line, is disposed in the seat portion, and a first guide a portion is disposed on the hole wall of the shaft hole and extends along the hole axis of the shaft hole for a predetermined length; a hammer portion is slidably disposed in one end of the hole shaft of the shaft hole; and a hammer shaft is coupled to the hammer portion Slidingly disposed in the other end of the hole shaft of the shaft hole, having a shaft body, a second guiding portion is disposed on the shaft body and slidingly connected with the first guiding portion; an elastic group having a first elastic member is disposed in the shaft hole and is interposed between the hammer portion and the impact shaft, and a second elastic member is received in the shaft hole and interposed between the second guide The portion and the guide are located at corresponding positions of the other end of the shaft hole shaft.

The first guiding portion is a recess that is recessed in the wall of the shaft hole and has a non-circular cross section.

The second guiding portion is a sheet-like body having a shape corresponding to the cross-sectional shape of the first guiding portion, and is protruded from the circumferential side annular surface of the shaft body.

Among them, the shaft body is cylindrical.

Wherein, the second elastic member is coaxially sleeved on the shaft body and abuts one end On the second guiding portion.

Wherein, the second guiding portion has a quadrangular shape.

The elastic assembly further includes a third elastic member disposed between the second guiding portion and the corresponding portion of the seat portion in the middle portion of the shaft hole.

Figure 6 is a cross-sectional view of a preferred embodiment of the present invention taken along the first line of Figure 6-6.

The seventh drawing is a schematic view of a component that can be applied as a massage end of a preferred embodiment of the present invention.

Referring to the entirety of the accompanying drawings, a modified structure (10) of a massage gun provided in a preferred embodiment of the present invention mainly comprises a casing (20) and a guide (30). A power member (40), a striker shaft (50), an elastic group (60), and a massage end portion (70).

The casing (20) is a hollow gun-shaped casing which is formed by connecting two halves of the casing to each other, and the inside of the casing can accommodate other constituent elements and form a proper grip for human hand to facilitate massage to the human body. The progress of the action.

The guide seat (30) is received in the casing (20), has a columnar seat portion (31), and a shaft hole (32) is disposed in the seat portion (31). And extending along the column axis thereof, a tubular hollow receiving portion (33) is coaxially fixed to one end of the seat portion (31) at one end, and connects the internal space with the shaft hole (32), a first guiding portion (34) having a quadrangular cross section is recessed on the hole wall of the shaft hole (32) and extending along the hole axis of the shaft hole (32) by an appropriate length; further, The shaft hole (32) is sequentially divided into a first aperture section (321), a second aperture section (322) and a third aperture section (323) along the axial direction, and the second aperture section is The inner diameter of (322) is larger than the inner diameter of the first aperture section (321), and smaller than the inner diameter of the third aperture section (323), and the first guiding portion (34) is interposed between the second aperture The segment (322) is between the third aperture segment (323).
