Description

Technical Field

[0001] The present application relates to the technical field of fascia guns, and in particular to a fascia gun transmission device. Background Art

[0002] The fascia gun, full name muscle fascia relaxation massage gun, is used for high-frequency impact therapy for fascia relaxation. The fascia gun generates 2000-5000 vibrations per minute, and impacts the target part of the body through the gun head to help relax and recover the muscle soft tissue and promote blood circulation. At the same time, it effectively dissipates a large amount of creatine produced by the human body due to fatigue in exercise, work, and life, and has a very good effect in relieving muscle fatigue.

[0003] The vibration principle of the fascia gun is that a motor is set inside the shell. When the motor is working, it is linked through a crank-connecting rod structure. A push rod is installed at its movable end. A transmission base is fixed at the end of the push rod, and the massage head is fixed on the transmission base, so that the massage head performs a linear reciprocating motion, so that the massage head can continuously relax the muscle tissue.

[0004] During use, the inventors found that when the transmission base slides back and forth, the outer wall of the transmission base will be in contact with the inner wall of the shell end as a whole, and the two will continue to rub, which is prone to wear and collision, and may cause damage and affect the service life. Summary of the invention

[0005] In order to stabilize the movement of the transmission base and increase the service life, the present application provides a fascia gun transmission device.

[0006] The fascia gun transmission device provided in this application adopts the following technical solution:

[0007] A fascia gun transmission device comprises a shell, a punch assembly is provided at the end of the shell, the punch assembly comprises a guide sleeve fixed to the end of the shell, a transmission base slidably connected in the guide sleeve, and a massage head arranged on the transmission base, a driving structure connected to the transmission base is provided in the shell, and no less than two elastic wear-resistant rings for abutting against the outer wall of the transmission base are axially provided on the inner wall of the guide sleeve.

[0008] By adopting the above technical solution, the driving structure will drive the moving base to move. During the transmission process, the transmission base will continue to slide, and its outer wall will collide with the elastic wear-resistant ring. Compared with the related technology, the friction area between the two will be reduced, and the damage will be reduced. In addition, the elastic wear-resistant ring can have a certain deformation ability, which can offset part of the impact force, further reducing the possibility of component damage, thereby improving the overall service life.

[0009] Preferably, the punch assembly further comprises a base and a shell, wherein the base is fixed to the end of the shell, the shell is arranged on the base, the guide sleeve is fixedly arranged between the base and the shell, and the guide sleeve is coated with a buffer.

[0010] By adopting the above technical solution, when the transmission base moves, it will impact the guide sleeve. At this time, the buffer can reduce the impact force to a certain extent, and the outer shell is relatively fixed on the shell, so the buffer can play a better buffering role.

[0011] Preferably, the driving structure comprises a driving motor arranged on the housing, a linkage rod with one end eccentrically arranged on the output shaft of the driving motor, and the other end of the linkage rod is hinged on the transmission base.

[0012] By adopting the above technical solution, after the driving motor works, one end of the linkage rod rotates eccentrically relative to the output shaft, and at this time the other end of the linkage rod drives the transmission base to move in the guide sleeve.

[0013] Preferably, a clamping ring is provided on the outer wall of one end of the guide sleeve away from the massage head, and the buffer member includes a first buffer portion located between the outer shell and the guide sleeve and a second buffer portion wrapped around the clamping ring, the upper side of the second buffer portion abuts against the base, and the lower side of the second buffer portion abuts against the outer shell.

[0014] By adopting the above technical solution, when the guide sleeve is subjected to impact forces in the axial direction and the radial direction, the clamping ring will mitigate the impact forces under the wrapping of the first buffer part and the second buffer part, and avoid the collision between the guide sleeve and the housing.

[0015] Preferably, there is a movable gap between the transmission base and the base and the shell.

[0016] By adopting the above technical solution, during the movement of the transmission base, there will be a movable gap that allows movement after deformation, and the transmission base will not get stuck under the premise of having an offset.

[0017] Preferably, an oil storage ring groove is provided on the inner wall of the guide sleeve and between two adjacent elastic wear-resistant rings.

[0018] By adopting the above technical solution, a lubricant such as lubricating oil can be added to the oil ring groove during installation, which plays a lubricating role during the movement of the transmission base and further reduces friction.

[0019] Preferably, the massage head is arranged on the transmission base through a connecting head, the connecting head is detachably connected to the transmission base, the transmission base has a receiving groove for the connecting head to be embedded, the circumferential side wall of the connecting head has a fixing ring, and the inner wall of the receiving groove has a fixing groove for the fixing ring to be embedded.

[0020] By adopting the above technical solution, when the connector needs to be replaced after use, the fixing ring can be disengaged from the fixing groove to facilitate installation and disassembly.

[0021] Preferably, the connector is provided with a fixing sleeve, the fixing ring is arranged on the fixing sleeve, and the fixing ring is made of elastic material.

[0022] By adopting the above technical solution, when the fixing ring is made of elastic material, it is convenient to deform during disassembly or installation.

[0023] Preferably, the connecting head is provided with a contact platform for contacting the massage head, and the end of the fixed sleeve close to the massage head is provided with an edge located on the side of the contact platform away from the massage head, one side of the edge contacts the end of the transmission base, and the other side contacts the contact platform.

[0024] By adopting the above technical solution, during the movement process, since the connecting head and the transmission base are separately arranged, during the movement process, when the two move relative to each other, the edge can play a buffering role between the two.

[0025] Preferably, the bottom of the transmission base has a first exhaust hole.

[0026] By adopting the above technical solution, when the connector is installed, since the fixing ring will contact the inner wall of the transmission base, the air inside the connector will be discharged from the first exhaust hole.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. During the movement of the transmission base, the friction between the whole and the guide sleeve is avoided, and the friction with the elastic wear-resistant ring is replaced, which will reduce the friction area between the two and reduce the damage. In addition, the elastic wear-resistant ring can have a certain deformation ability, which can offset part of the impact force, further reduce the possibility of component damage, and thus increase the overall service life;

[0029] 2. When the guide sleeve is subjected to impact force in the axial and radial directions, the clamping ring will reduce the impact force under the wrapping of the first buffer part and the second buffer part, and prevent the guide sleeve from colliding with the housing;

[0030] 3. The connector and the transmission base are set separately, and the edge can act as a buffer between the two during movement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings.

[0039] A fascia gun transmission device, referring to Figure 1 , Figure 2 , including a shell 100, a punch assembly 110 is provided at the end of the shell 100, the punch assembly 110 includes a guide sleeve 111 fixed to the end of the shell 100, a transmission base 112 slidably connected in the guide sleeve 111, and a massage head 113 arranged on the transmission base 112, a driving structure 120 connected to the transmission base 112 is provided in the shell 100, and the driving structure 120 will make the transmission base 112 slide in the guide sleeve 111, so that the massage head 113 moves.

[0040] The driving structure 120 includes a driving motor 121 fixedly connected to the housing 100, a linkage rod 122 with one end eccentrically arranged on the output shaft of the driving motor 121, a rotating wheel 123 fixed on the output shaft of the driving motor 121, one end of the linkage rod 122 is eccentrically hinged on the rotating wheel 123, and a counterweight block 124 is integrally arranged at a position opposite to the hinge point of the rotating wheel 123 and the linkage rod 122, and the other end of the linkage rod 122 is hinged on the transmission base 112. When the driving motor 121 is working, one end of the linkage rod 122 is driven by the rotating wheel 123 to perform eccentric movement, thereby driving the transmission base 112 to move.

[0041] Reference Figure 3 The punch assembly 110 also includes a base 114 and a shell 115. The base 114 is clamped and fixed at the end of the shell 100. The shell 115 is fixed to the base 114 by bolts. The guide sleeve 111 is clamped and fixed between the base 114 and the shell 115. A clamping ring 116 is integrally provided on the outer wall of the end of the guide sleeve 111 away from the massage head 113. The clamping ring 116 extends from the outer wall of the guide sleeve 111 toward the side away from the central axis of the guide sleeve 111.

[0042] At the same time, the guide sleeve 111 is covered with a buffer 130. When the transmission base 112 is moving, the guide sleeve 111 can reduce the impact force through the buffer 130. The buffer 130 includes a first buffer portion 131 located between the shell 115 and the guide sleeve 111 and a second buffer portion 132 wrapped on the clamping ring 116. The first buffer portion 131 and the second buffer portion 132 are integrally formed and made of elastic material, such as silicone. The upper side of the second buffer portion 132 contacts the base 114, and the lower side of the second buffer portion 132 contacts the shell 115. When the transmission base 112 is moving, the buffer 130 can buffer the impact force in both the axial and radial directions. In order to avoid the situation where the offset generated during buffering causes jamming, there is a movable gap between the transmission base 112 and the base 114 and the shell 115.

[0043] The inner wall of the guide sleeve 111 is axially embedded with at least two elastic wear-resistant rings 133 for contacting the outer wall of the transmission base 112. In this embodiment, the elastic wear-resistant ring 133 is made of fluororubber. During the movement of the transmission base 112, its outer wall will contact the elastic wear-resistant ring 133. In the case of reducing friction, there is also a certain buffer space. In order to further reduce friction, an oil storage groove 134 is provided on the inner wall of the guide sleeve 111 and between two adjacent elastic wear-resistant rings 133. During installation, a medium such as lubricating oil is pre-placed in the oil storage groove 134. During the movement, the elastic wear-resistant ring 133 can also play a sealing role, so that the lubricating medium can be retained for a long time.

[0044] Reference Figure 3 , Figure 4 The transmission base 112 is detachably connected with a connector 140, and the massage head 113 is installed on one end of the connector 140 away from the transmission base 112. The transmission base 112 has a receiving groove 200 for the connector 140 to be embedded in, and a fixing ring 210 is provided on the circumferential side wall of the connector 140. The inner wall of the receiving groove 200 has a fixing groove 211 for the fixing ring 210 to be embedded in. In this embodiment, the connector 140 is hollow, and the end of the connector 140 away from the limiting protrusion is set in a frustum shape, which is convenient for insertion into the transmission base 112.

[0045] Reference Figure 4 , Figure 5 , and it is further convenient to install the connector 140 into the transmission base 112. The connector 140 is sleeved with a fixing sleeve 212, and the fixing ring 210 is integrally arranged on the fixing sleeve 212. The fixing sleeve 212 is made of rubber and can be deformed. At the same time, the connector 140 is integrally provided with a contact platform 215 for contacting the massage head 113. The end of the fixing sleeve 212 close to the massage head 113 is provided with an edge 216 located on the side of the contact platform 215 away from the massage head 113. One side of the edge 216 contacts the end of the transmission base 112, and the other side contacts the contact platform 215. During use, the edge 216 can play a buffering role between the connector 140 and the transmission base 112.

[0046] Reference Figure 4 , Figure 6 When the connector 140 is inserted into the transmission base 112, the fixed ring 210 will contact the inner wall of the transmission base 112, and the original gas inside needs to be discharged. The bottom of the transmission base 112 has a first exhaust hole 213 for easy installation. At the same time, when the fixed sleeve 212 is installed, in order to make the fixed sleeve 212 fit the bottom of the fixed ring 210 groove, the fixed sleeve 212 has a second exhaust hole 214.

[0047] The implementation principle of a fascia gun transmission device in an embodiment of the present application is as follows: when the driving motor 121 is working, it will drive the linkage rod 122 to move, so that the transmission base 112 moves in the guide sleeve 111. During the movement of the transmission base 112, the transmission base 112 will contact with the elastic wear-resistant ring 133, thereby reducing the effect of friction. In addition, since the linkage rod 122 will have an impact force on the guide sleeve 111 during the movement of the transmission base 112, the elastic wear-resistant ring 133 will also be deformed.

[0048] At the same time, during the movement, the buffer member 130 will also play a buffering role. During the axial and radial displacement processes, the buffer member 130 can be deformed, further improving the stability of the transmission base 112 during the movement.

[0049] In this embodiment, in order to facilitate installation and disassembly, the transmission base 112 and the connecting head 140 are separately provided. At this time, during the movement, the edge 216 between the two can play a buffering role, which can reduce the possibility of shaking and damage during the movement of the two.

[0050] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
