Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities, in particular to a fascia gun which is easy to assemble and disassemble. Background Art
[0002] The fascia gun, also known as the deep myofascial impactor, is a soft tissue rehabilitation tool. Its working principle is: using its internal special high-speed motor to drive the "gun head", generating high-frequency vibrations to act on the deep muscle, thereby reducing local tissue tension, relieving pain, and promoting blood circulation. It is currently mostly used to relax muscles after exercise.
[0003] The existing fascia gun usually has a shell including a gripping part, an impact part, and a column top. The gripping part is used for holding by hand, the impact part is used to install the "massage gun head", and the column top is used to install the internal electronic control module. At present, the shell is assembled by one-piece injection molding or by setting the upper and lower shells to be screwed together. The one-piece injection molded shell is not convenient for assembly and subsequent maintenance after failure, while the upper and lower shells are screwed together for assembly. The internal battery, transmission mechanism and other components are not fixed after assembly, and are easy to slide and collide with the shell. Summary of the Invention

[0009] The impact portion port is provided with a front cover, the front cover is provided with a plurality of first buckles, and the front cover is detachably connected to the shell through the first buckles.
[0010] The impact part is provided with a bracket, which is fixed to the shell by screws. The bracket divides the impact part into an upper cavity and a lower cavity. The battery is installed in the upper cavity, and the transmission mechanism is arranged in the lower cavity.
[0011] The transmission mechanism includes an eccentric cam and a connecting rod. One end of the eccentric cam is connected to the motor output shaft, and the other end is connected to the end of the connecting rod. The rotation of the motor drives the eccentric cam to rotate, thereby driving the connecting rod to perform horizontal reciprocating motion. The connecting rod is provided with a mounting portion for mounting a massage head on one side relative to the eccentric cam.
[0012] A sliding bearing is provided between the mounting portion and the housing.
[0013] The port at the top of the column is provided with a rear cover, and the rear cover is provided with a plurality of second buckles. The rear cover is detachably connected to the top of the column through the second buckles.

The main control board is electrically connected to the battery and the motor.
[0015] The upper cover is provided with a convex grip portion for holding.
[0016] The beneficial effects of the utility model are as follows: the utility model arranges an upper cover on the shell, and the shell and the upper cover are detachably connected by a hook, which is convenient for disassembly and assembly. When the upper cover is not installed, it has a larger opening for assembling internal parts. The shell is provided with an annular groove that is adapted to the contour of the upper cover, and a protrusion is provided on the inner side of the annular groove. The upper cover is provided with a number of limiting ribs that are adapted to the protrusion. When the battery, transmission mechanism and other components are assembled to the shell, the upper cover is installed so that the limiting ribs and the protrusion cooperate to fix the battery, transmission mechanism and other components to prevent them from sliding and avoid collision with the shell.

[0021] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0022] like Figure 1-4 As shown, a fascia gun that is easy to disassemble and assemble includes a shell 1, in which a motor 17, a battery 7, a transmission mechanism and an electronic control module 9 are installed. The shell 1 has a connected gripping part 11, an impact part 13, and a column top 12. The motor 17 is arranged on the gripping part 11, the battery 7 and the transmission mechanism are arranged on the impact part 13, and the electronic control module 9 is arranged on the column top 12.
[0023] The housing 1 is provided with a top cover 2. The housing 1 is provided with an annular groove 10 that matches the contour of the top cover 2, ensuring that the housing 1 and top cover 2 are installed without protrusions, improving the aesthetics. A raised portion 14 is provided on the inner side of the annular groove 10, and the top cover 2 is provided with several retaining ribs 22 that match the raised portions 14. The bottom of the retaining ribs 22 has a mating portion 23, which is a stepped structure. The mating portion 23 cooperates with the raised portion to secure components such as the battery and transmission mechanism, preventing them from sliding and colliding with the housing. Several hooks 24 are provided on one side of the top cover 2. The top cover 2 is detachably connected to the housing 1 via these hooks, facilitating disassembly and assembly for subsequent maintenance. The top cover 2 is also provided with a raised grip 21 for easy gripping during removal.
[0024] The upper cover 2 is provided with a retaining post 25 on the side opposite the hook 24. A retaining groove 15 is provided within the housing 1 to engage with the retaining post 25. The retaining post 25 and the retaining groove 15 ensure that the upper cover does not slip. Furthermore, the retaining post 25 and the retaining groove 15 are provided with screw holes, allowing the upper cover 2 and the housing 1 to be further secured with screws.
[0025] In this embodiment, the port of the impact part 13 is configured with a front cover 16, and the front cover 16 is provided with a plurality of first clips 41. The front cover 16 is detachably connected to the shell 1 through the first clips 41. Since the impact part needs to frequently replace the massage head 101, when the massage head 101 is stuck after installation, the massage head 101 can be removed by quickly disassembling the front cover 16.
[0026] In this embodiment, the impact part 13 is provided with a bracket 8, which is fixed to the shell 1 by screws. The bracket 8 divides the impact part 13 into an upper cavity and a lower cavity. The battery 7 is installed in the upper cavity and the transmission mechanism is arranged in the lower cavity. This structure is conducive to saving installation space, making the fascia gun smaller, more convenient and practical.
[0027] In this embodiment, the transmission mechanism includes an eccentric cam 18 and a connecting rod 19. One end of the eccentric cam 18 is connected to the output shaft of the motor 7, and the other end is connected to the end of the connecting rod 19. The rotation of the motor 7 drives the eccentric cam 18 to rotate, thereby driving the connecting rod 19 to perform a lateral reciprocating motion. The connecting rod 19 is provided with a mounting portion 20 for mounting the massage head 101 on one side relative to the eccentric cam 18. A sliding bearing 30 is provided between the mounting portion 20 and the housing 1. The sliding bearing 30, on the one hand, serves to fix the mounting portion 20, and on the other hand, reduces the friction when the mounting portion 20 performs a lateral reciprocating motion, thereby extending the service life.
[0028] In this embodiment, the port of the column top 13 is configured with a back cover 6, and the back cover 6 is provided with a plurality of second clips 42. The back cover 6 is detachably connected to the column top 13 through the second clips 42. The electronic control module 9 includes a main control board, which is fixed to the back cover 6 by screws. The main control board is provided with a switch 3, a charging port 4, and an indicator light 5. The switch 3, the charging port 4, and the indicator light 5 extend to the outer surface of the back cover 6 for user convenience. The main control board is electrically connected to the battery 7 and the motor 17. When the electronic control module 9 fails, it can be repaired by quickly removing the back cover 6.
[0029] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
