[0024] Please see Figures 1 to 8 The utility model discloses massage head electricity conduction structure for muscle fascia gun, including main body 1, sheet conduction piece 2, conduction column 3 and limit piece 4, the main body 1 is provided with installation groove 11, a plurality of limit posts 12 are arranged in the wall of installation groove 11, the edge of sheet conduction piece 2 is provided with the first limit slot 21 matched with limit post 12, limit piece 4 is provided with the second limit slot 41 matched with conduction column 3, wherein, when limit piece 4 is arranged in installation groove 11, conduction column 3 is electrically connected with sheet conduction piece 2.
[0025] In the above embodiment, the combination of sheet conduction piece 2 and conduction column 3 is adopted, which simplifies the circuit connection structure and replaces the traditional fragile circuit board structure. The structure is composed of four parts of the main body 1, the sheet conduction piece 2, the conduction column 3 and the limit piece 4. The cold and hot functions of the main body are triggered by the communication between any two conduction columns 3 and the sheet conduction piece 2.
[0026] The main body 1 serves as a support frame of the overall structure and is provided with an installation groove 11 for accommodating and fixing the limit piece 4. A plurality of limit posts 12 are arranged in the wall of the installation groove 11 for limiting the sheet conduction piece 2. The sheet conduction piece 2, as an electrical conduction component, has a first limit slot 21 matched with the limit posts 12 arranged at the edge thereof. Stable installation can be achieved by simple plug-in connection, and smooth transmission of electrical signals is ensured.
[0027] In order to further enhance the stability of the connection and the reliability of the electrical conduction, the limit piece 4 is provided. The limit piece 4 is provided with a second limit slot 41 matched with the conduction column 3. When the limit piece 4 is installed into the installation groove 11 of the main body 1, the conduction column 3 can be inserted into the second limit slot 41, thereby limiting the conduction column 3 and achieving electrical connection with the sheet conduction piece 2. This design not only simplifies the electrical connection process, but also greatly reduces the problem of poor contact caused by vibration.
[0028] By adopting the combination of the sheet-shaped conducting piece 2 and the conducting column 3, and with the stable limiting of the limiting piece 4, better anti-vibration performance is achieved, and damage due to vibration is avoided; meanwhile, the addition of the limiting piece 4 further enhances the stability of the connection, so that the entire electrical connection system can maintain stable operation in a harsh working environment, thereby significantly improving the durability and reliability of the fascia gun.
[0029] Please refer to Figures 1 to 8 In another embodiment, the conducting column 3 is provided with three. The sheet-shaped conducting piece 2 is a copper sheet. The surface of the sheet-shaped conducting piece 2 is engraved with two annular circular grooves 22, and the outer ring annular circular groove 22 is larger than the inner ring annular circular groove 22.
[0030] In the above embodiment, the number of conducting columns 3 is provided with three, which are evenly distributed in the mounting groove 11 of the main body 1, and are used to establish electrical connection with the sheet-shaped conducting piece 2 and external elements. The sheet-shaped conducting piece 2 is made of high-quality copper sheet, which has good electrical conductivity and durability to ensure stable transmission of electrical signals.
[0031] The copper sheet is engraved with two annular circular grooves 22, and the diameter of the outer ring circular groove is larger than that of the inner ring circular groove. Two conducting columns 3 are in contact with the copper sheet, and one conducting column 3 is in a void state corresponding to the annular circular groove 22. During the process of installing the ordinary massage head into the main machine, the two conducting columns 3 can be connected to each other, while the third conducting column 3 remains in a void state and does not participate in the current electrical connection. The sensing function of whether the massage head is installed is realized, that is, when the massage head is correctly installed, the two connected conducting columns 3 trigger the corresponding electrical signal, thereby starting or adjusting the working mode of the fascia gun; if the massage head is not installed or improperly installed, the void state of the conducting column 3 remains unchanged, preventing equipment misoperation or damage.
[0032] Please refer to Figures 1 to 8 In another embodiment, the limiting piece 4 is also provided with a connecting groove 42, and a plurality of threaded holes 43 are arranged in the connecting groove 42.
[0033] In the above embodiment, a plurality of threaded holes 43 are distributed in the connecting groove 42, which are used to cooperate with the massage head. When the massage head needs to be installed on the main machine, the connecting part is first aligned with the connecting groove 42 of the limiting piece 4, and then the screw is locked.
[0034] Please refer to Figures 1 to 8 In another embodiment, the mounting groove 11 is also provided with a retaining hole 13. The bottom edge of the sheet-shaped conducting piece 2 between the two first limiting grooves 21 is raised and has a hook shape. When the sheet-shaped conducting piece 2 is arranged in the mounting groove 11, the hook-shaped bottom edge of the sheet-shaped conducting piece 2 is embedded in the mounting groove 11.
[0035] In the above embodiment, the bottom edge of the sheet-shaped conducting piece 2 is in a raised state between the two first limiting grooves 21, forming a hook-shaped structure. This allows the sheet-shaped conducting piece 2 to fit more tightly in the installation groove 11 during installation. When the sheet-shaped conducting piece 2 is placed in the installation groove 11, the hook-shaped part of its bottom edge will naturally embed into the retaining hole 13 of the installation groove 11. This embedded connection not only increases the contact area between the sheet-shaped conducting piece 2 and the installation groove 11, but also effectively prevents the sheet-shaped conducting piece 2 from moving or falling out under the action of vibration or external force through physical locking.
[0036] Please refer to Figures 1 to 8 , the limiting column 12 is arranged oppositely up and down and oppositely left and right.
[0037] The limiting column 12 corresponding up and down mainly plays a limiting role in the vertical direction. They are respectively located at the top and bottom of the installation groove 11, and tightly contact with the upper and lower edges of the sheet-shaped conducting piece 2, preventing the sheet-shaped conducting piece 2 from deviating or shaking in the vertical direction. This design ensures the vertical stability of the sheet-shaped conducting piece 2 in the installation groove 11.
[0038] At the same time, the limiting column 12 corresponding left and right is responsible for limiting in the horizontal direction. They are symmetrically arranged on the left and right sides of the installation groove 11, and accurately aligned with the first limiting groove 21 of the side edge of the sheet-shaped conducting piece 2. When the sheet-shaped conducting piece 2 is placed in the installation groove 11, these limiting columns 12 will naturally embed into the first limiting groove 21, thereby limiting the sheet-shaped conducting piece 2 in the horizontal direction. This design ensures the stability and accuracy of the sheet-shaped conducting piece 2 in the horizontal direction.
[0039] In summary, the layout of the limiting column 12 arranged oppositely up and down and oppositely left and right not only provides all-round limiting support for the sheet-shaped conducting piece 2, but also ensures its uniform stress in the installation groove 11. This design effectively prevents the sheet-shaped conducting piece 2 from deviating and shaking during installation and use, improving the stability and reliability of electrical connection.
[0040] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and any simple modification, equivalent change and modification of the above embodiment based on the technical essence of the present application are still within the scope of the technical solution of the present application.
