Description

Massage gun with direction control {Massage gun with direction control}

The present invention relates to a massage gun, and more particularly, to a massage gun capable of direction control to perform massage for each part of the body.

People in modern cities are living faster and faster. In a tense life, most people suffer from various stresses. After long-term labor or work, the muscles and nerves of the body get tired easily and should be recovered through appropriate rest, but the body itself takes a very long time to recover. , If an external massage tool is used, the recovery time can be shortened, so there are a lot of massage tools on the market.

However, most of the existing massage devices sold in the market are mid- to large-sized devices such as massage chairs and massagers. If users want to use these devices, they must be used in a specific place, and relatively high demands are required for usage time. Since it causes certain inconvenience to the people, the relatively small volume of the massage stick gradually begins to come into people's field of vision.

Currently, the structural principle of the handheld massager on the market is basically using one small motor to operate the eccentric hammer together, and the inertia generated by the eccentric hammer causes the vibrating body to generate periodic vibrations to achieve the purpose of massaging the human body do. However, existing handheld massage rods have a complicated internal structure, relatively high production cost, and commonly used small massage hammers have defects such as fixed massage head shape, non-replaceable, and relatively large vibration and noise.

Specifically, in the rotary connector 400, a coupling ring 70 is formed on a portion of the first coupling protrusion 410-1, and a coupling ring accommodating portion is formed inside the first coupling protrusion accommodating portion 420-1. 80 is formed so that coupling is possible through them, and the first spring 430-1) is inserted between the first coupling protrusion 410-1 and the coupling ring 70 to provide elastic force while massaging the massage unit 200 And smooth movement of the grip part 300 can be induced.

The first ball bearing 440-1 is accommodated in the corresponding fixing grooves 50 in the lower portion of the massage unit 200 and the upper portion of the grip unit 300 to be fixed while controlling the movements of the massage unit 200 and the grip unit 300. can Specifically, a first guide rail 440-1 in which a plurality of fixing grooves 50 are arranged in a circular shape in the lower part of the massage unit 200 and the upper part of the grip part 300 and connect each of the fixing grooves 50 in a circular shape. is formed so that the first ball bearing 450-1 moves along the first guide rail 440-1 by the elasticity of the first spring 430-1 and is seated in each of the fixing grooves 50 for massage. The unit 200 and the grip unit 300 may be fixed.

The rotation connector 400 according to another embodiment of the present invention includes a second coupling protrusion 410-2, a second coupling protrusion accommodating portion 420-2, a second spring 430-2, a second guide rail ( 440-2) and a second ball bearing 450-2.

The second coupling protrusion 410 - 2 may protrude from the lower part of the massage unit 200 .

The second coupling protrusion accommodating portion 420-2 is formed on the upper part of the grip part 300 to correspond to the second coupling protrusion 410-2, and the second coupling protrusion 410-2 can be rotatably coupled thereto. .

The second spring 430-2 may be coupled while surrounding the second coupling protrusion 410-2 to provide elastic force.

The second guide rails 440-2 are composed of a plurality and provided radially on the upper part of the grip part 300, and both ends may have fixing grooves 50 of a set size formed thereon.

The second ball bearing 450-2 is accommodated in the corresponding fixing grooves 50 in the lower portion of the massage unit 200 and the upper portion of the grip unit 300 to be fixed while controlling the movements of the massage unit 200 and the grip unit 300. can Hereinafter, the operating principle of the rotary connector 400 is similar to that described above except for the portion where the guide rails 440-1 and 2 are arranged radially in a circle.

Specifically, the current plate 40 installed on each side of the massage unit 200 and the grip unit 300 transmits current from the battery to the motor of the massage unit 200 through the grip unit 300. Since a separate wire is not required, twisting of the wire by the rotary connector 400 can be prevented.

The current plate 40 refers to a structure in which current is concentrated on a thin and wide plate. It can be seen as if a large number of wires carrying current in the same direction are gathered in a thin and wide layer. Of course, there are no wires in real space, but the movement of a large number of charged particles can create an ammeter structure like this.

According to one embodiment of the present invention, it is possible to control the direction of the massage unit 200 at various angles set by using the rotary connector 400 connecting the massage unit 200 and the grip unit 300 .
