Technical Field

[0001] The utility model relates to the technical field of fascia guns, and more specifically, to a mounting structure of a fascia gun. Background Art

[0002] The fascia gun is a massage instrument that uses vibration to act on the muscles to reduce local tissue tension, relieve pain, and promote blood circulation. A conventional fascia gun includes a body and a handle. The body includes an upper shell and a lower shell. The lower shell and the handle are integrally formed, and the upper shell and the lower shell are connected to form an installation space for accommodating a piston, a bushing, a button, and an electrical connection line. This molding and connection method will increase the number of parts of the fascia gun, making the overall structure of the fascia gun bloated and heavy. The user's arm is tired when using it. The general fascia gun buttons are plastic buttons, which are prone to jamming.

[0003] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fascia gun installation structure which is easy to assemble, has good installation stability and reasonable space utilization.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a mounting structure of a fascia gun, comprising an outer shell and a button module arranged in the outer shell, the outer shell comprising an upper shell, a lower shell and a front cover, a through groove 1 for installing the front cover is arranged on the side wall of the upper shell, the button module is arranged on the top of the upper shell, the button module comprises an external button, a light guide and an internal button with elastic force, an upper end of the upper shell is provided with a mounting groove for inserting the light guide and the external button, an opening for accommodating the internal button is opened at the center position of the light guide, a buckle 1 is provided on the lower end surface of the external button, a buckle 2 which is fixedly connected to the inner wall of the opening of the light guide and cooperates with the buckle 1, a boss is fixedly connected to the outer wall of the light guide, and a groove for inserting the boss is provided on the inner wall of the upper shell.

[0006] By adopting the above technical solution, in the process of assembling the key module with the fascia gun, first, the external key is installed in the light guide, so that the buckle one and the buckle two are buckled together. The light guide is used as a decorative part of semi-transparent light and also as an assembly component. The assembly with the external key is achieved by setting the buckle two. The next step is to put the internal key into the opening opened in the center of the light guide. The middle of the internal key is hollow, and then the key components on the key circuit board in the fascia gun are inserted into the internal key. At this time, the key circuit board is fixed to the light guide by screws. This component can be pre-assembled independently for easy assembly. Then the light guide is installed in the upper shell. At this time, the boss on the light guide will be inserted into the corresponding groove on the upper shell to prevent the key module from rotating during use. It is also used for positioning. After the assembly is completed, it is a separate key semi-finished product, which is convenient for pre-assembly or testing. Since the internal key is elastically set, such as silicone, rubber, rubber coating, spring, etc. to improve the rebound touch and increase the inclusiveness, the elasticity of the internal key can be used to achieve automatic rebound after the switch is pressed.

[0007] The utility model is further configured as follows: a wiring groove 1 is arranged on the inner wall of the upper shell.

[0008] By adopting the above technical solution, the wiring groove opened inside the upper shell can make the wiring inside the fascia gun more regular and orderly, and the wiring installation is more convenient, avoiding the line affecting the motor and eccentric moving parts inside the fascia gun.

[0009] The utility model is further configured as follows: a motor bracket is installed inside the upper shell, the motor bracket is in a hollow cylindrical shape and is coaxially arranged with the upper shell, a through slot 2 corresponding to the shape and position of the through slot 1 is arranged on the side wall of the motor bracket, an inner lining is installed inside the lower shell, a motor mounting hole group is arranged on the top surface of the motor bracket, a bottom mounting hole group for connecting with the inner lining is arranged at the bottom of the motor bracket, and a side mounting hole group for connecting with the upper shell is arranged on the side wall of the motor bracket.

[0010] By adopting the above technical scheme, the bottom mounting hole group of the motor bracket can not only be directly featured on the mold, but also occupies a small space. At the same time, a second through slot and an opening on the top surface are provided to ensure that the inner cavity of the motor bracket continues to be used as a movement space. The component is made into a circular motor bracket according to the inner circle of the outer shell, and the center of the circle is coaxial with the upper shell, which solves the problem of difficult installation and limiting. The side mounting hole group is then used to fix the motor bracket with the middle front cover by screws, and the bottom mounting hole group is screwed together with the inner lining. In this way, the motor bracket is fixed on three sides to ensure the stability of the motor bracket during operation.

[0011] The utility model is further configured as follows: a connection hole group is fixedly connected to one end of the lining close to the motor bracket, the number and position of the connection hole group correspond to the bottom mounting hole group, and a limit platform is provided on the connection hole group for limiting the bottom mounting hole group.

[0012] By adopting the above technical solution, in the process of connecting the bottom mounting hole group and the lining together by screws, when the bottom mounting hole group and the lining are docked, the limit platform will limit the bottom mounting hole group to prevent the bottom mounting hole group from rotating and affecting the screwing in of the screws, thereby facilitating the locking of the screws.

[0013] The utility model is further configured as follows: a battery limiting groove is arranged on the inner wall of the lining, and a second wiring groove is arranged on the inner wall of the lining.

[0014] By adopting the above technical solution, the battery limiting groove can limit the battery installed in the lining, making the battery installation more stable. The wiring groove two and the wiring groove one are located on the same straight line in the vertical direction. A flat section is provided at the position corresponding to the opening of the motor bracket and the upper portion of the wiring groove two. The line will pass through the flat section of the motor bracket and the channel of the upper shell from the wiring groove one, and then enter the position of the wiring groove two on the side of the battery, making the wiring arrangement more regular and rational.

[0015] The utility model is further configured as follows: an end of the lower shell away from the upper shell is provided with an inwardly inclined tight-fitting section, the outer wall of the lining is fixedly connected with a limiting rib for tight fitting with the tight-fitting section of the lower shell, and the lower end of the lining is fixedly connected with a positioning rib.

[0016] By adopting the above technical solution, since the battery and wiring are installed in the lining, the setting of the lining can realize the assembly of the entire machine, testing and use without installing the lower shell, and because the battery is already installed in the inner cavity of the lining, after the charging board is plugged into the wiring harness, it is installed on the positioning ribs at the bottom of the lining. The terminals of the circuit board just serve as the battery press to prevent the battery from falling out, and the tight-fitting section with an inclined processing can further facilitate the installation of the lower shell.

[0017] The utility model is further configured as follows: a plurality of positioning blocks are arranged on the outer wall of the liner, and a card slot for the positioning blocks to be inserted is arranged on the inner wall of the lower shell.

[0018] By adopting the above technical solution, when the lower shell needs to be installed after confirming the function, the position is matched with the positioning block of the lower outer shell to avoid wrong installation of the lower shell and prevent the lower shell from rotating. Through the press-fitting fixture, the tight-fitting limit rib and the tight-fitting section inside the lower outer shell are matched and locked to complete the entire installation of the fascia gun.

[0019] In summary, the utility model has the following beneficial effects:

[0020] The button module of the fascia gun of the utility model is integrated with the external button and the internal button by arranging a second buckle on the light guide, which makes assembly faster. The arrangement of the wiring groove can make the internal space arrangement of the fascia gun more stable and reasonable. The motor bracket is fixedly installed on three sides, which can make the internal structure of the fascia gun more stable and more convenient for disassembly and assembly. The multiple limiting functions of the inner lining by the limiting ribs and the positioning blocks can make its installation more reliable and stable, making the overall structural arrangement of the fascia gun more reasonable and stable, and making installation and disassembly more convenient.
