Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a fascia gun. Background Technology

[0002] Massage equipment has been widely used in fitness, rehabilitation, and daily health care. Among them, the fascia gun, as an electric massage tool, uses a massage head to generate high-frequency vibrations to relax the muscles and fascia. The fascia gun uses a motor to drive the massage head, generating high-frequency impact that penetrates deep into muscle tissue to relieve muscle stiffness and soreness, and promote blood circulation. However, in existing fascia guns, the assembly method of fixing the ball bearings inside the gun is relatively complex, which increases the production cost and fails to meet user needs. Utility Model Content

[0003] The main purpose of this invention is to propose a fascia gun that aims to reduce the production cost of fascia guns.

[0004] To achieve the above objectives, the fascia gun proposed in this utility model includes a housing; a driver disposed within the housing; a buffer assembly including a buffer member and multiple balls, the buffer member being elastic, the buffer member having a first mounting hole extending through its thickness direction, the wall of the first mounting hole having multiple mounting grooves arranged circumferentially thereon, the mounting grooves having openings facing the inner side of the first mounting hole, the balls being mounted into the mounting grooves through the openings, the balls being disposed within the buffer member and rotatably disposed relative to the buffer member; and a connecting rod assembly passing through the first mounting hole, the driver driving and connecting the connecting rod assembly, the connecting rod assembly slidingly abutting against the multiple balls, and the connecting rod assembly being used for mounting a massage head.

[0005] In one embodiment, the buffer is a one-piece structure, and / or the buffer is made of any one of silicone, rubber, or silicone rubber.

[0006] In one embodiment, at least a portion of the balls are exposed outside the mounting groove through the slot, the radius of the slot being smaller than the radius of the mounting groove.

[0007] In one embodiment, the ball bearing is made of plastic material.

[0008] In one embodiment, the linkage assembly further includes a sliding sleeve and a connecting rod. The sliding sleeve is sleeved on the outer periphery of the connecting rod and is located between the connecting rod and the plurality of balls. The sliding sleeve slidably abuts against the plurality of balls.

[0009] In one embodiment, the sliding sleeve compresses the buffer member through the ball bearings to induce compression deformation in the buffer member.

[0010] In one embodiment, the fascia gun further includes a transmission component located between the driver and the connecting rod. The driver drives the transmission component, and the transmission component is connected to the connecting rod in a driving manner.

[0011] In one embodiment, the linkage includes a first connecting segment and a second connecting segment connected to each other. The first connecting segment has a second mounting hole for mounting a massage head, and the second connecting segment has a third mounting hole on a side opposite to the second mounting hole for mounting at least a portion of the transmission element.

[0012] In one embodiment, the first connecting segment is bent relative to the second connecting segment, and a clearance space for placing the battery is formed between the first connecting segment and the second connecting segment.

[0013] In one embodiment, the fascia gun further includes a control assembly electrically connected to the driver, the control assembly being located on a side opposite to the buffer.

[0014] This invention employs ball bearings installed in the mounting groove from the groove opening. The ball bearings are located within the buffer component and are rotatably positioned relative to the buffer component, allowing multiple ball bearings to slide and abut against the outer peripheral wall of the connecting rod assembly.

[0026] This utility model proposes a fascia gun 10.

[0027] Please see Figures 1 to 4 In one embodiment of this utility model, the fascia gun 10 includes a housing 101, a driver 3, a buffer assembly 1, and a connecting rod assembly 2. The driver 3 is disposed within the housing 101; the buffer assembly 1 includes a buffer member 11 and a plurality of balls 12. The buffer member 11 is elastic and has a first mounting hole 111 extending through its thickness direction. The wall of the first mounting hole 111 has a plurality of mounting grooves 1111 arranged circumferentially thereon. The mounting grooves 1111 have openings 1112 facing the inner side of the first mounting hole 111. The balls 12 are mounted into the mounting grooves 1111 through the openings 1112. The balls 12 are disposed within the buffer member 11 and are rotatably disposed relative to the buffer member 11. The connecting rod assembly 2 passes through the first mounting hole 111. The driver 3 drives and connects the connecting rod assembly 2. The connecting rod assembly 2 slides against the plurality of balls 12. The connecting rod assembly 2 is used for mounting a massage head.

[0028] The technical solution of this utility model employs ball bearings 12 installed from the groove 1112 into the mounting groove 1111. The ball bearings 12 are disposed within the buffer member 11 and are rotatably arranged relative to the buffer member 11, allowing multiple ball bearings 12 to slide and abut against the outer peripheral wall of the connecting rod assembly 2. By using a single buffer member 11, this application simplifies the assembly process that requires splicing buffer members 11 during production, reducing the production cost of the fascia gun 10. Compared with the existing assembly method in which the mounting groove 1111 is formed by splicing semi-grooves on two buffer members 11, the buffer member 11 of this application can avoid the misalignment problem that occurs when two buffer members 11 are spliced ​​into the mounting groove 1111, thus improving the production efficiency of the fascia gun 10.

[0029] In this embodiment, the fascia gun 10 includes a housing 101 and a driver 3, a buffer assembly 1, and a connecting rod assembly 2 disposed within the housing 101. The driver 3 is located on one side of the connecting rod assembly 2, and the driver 3 drives the connecting rod assembly 2 to reciprocate along the axial direction of the first mounting hole 111 under the drive of the driver 3. In order to prevent the vibration generated by the reciprocating movement of the connecting rod assembly 2 from being transmitted to the housing 101, this application uses a buffer assembly 1 disposed between the connecting rod assembly 2 and the housing 101. The buffer assembly 1 can buffer the force transmitted from the connecting rod assembly 2 to the housing 101, thereby improving the vibration reduction effect. The buffer 11 is provided with a first mounting hole 111 that extends through its thickness direction. One end of the connecting rod assembly 2 can pass through the first mounting hole 111. The buffer 11 is installed inside the housing 101, which makes it easier to install the connecting rod assembly 2. The first mounting hole 111 has multiple mounting grooves 1111 arranged circumferentially on its wall. The balls 12 can be installed in the mounting grooves 1111 and roll against the outer wall of the connecting rod assembly 2, preventing wear on the buffer member 11 caused by the reciprocating movement of the connecting rod assembly 2. The balls 12 also support the connecting rod assembly 2; the multiple balls 12 surround the connecting rod assembly 2 and slide against it, limiting the left-right swaying of the connecting rod assembly 2. Compared to the existing method of using two buffer members 11 spliced ​​together to form the mounting groove 1111, this application improves the stability of the connection between the balls 12 and the buffer member 11 by using multiple balls 12 located in the mounting grooves 1111 of the buffer member 11. Furthermore, by separately opening the mounting grooves 1111 and the first mounting hole 111 on one buffer member 11, the production cost of the fascia gun 10 is reduced, and the situation where the two buffer members 11 misalign during operation, causing the balls 12 to fall off, is avoided. Multiple mounting grooves 1111 are formed in the wall of the first mounting hole 111 on the buffer member 11, and the multiple mounting grooves 1111 are arranged circumferentially along the wall of the first mounting hole 111, which can facilitate the sliding contact between the ball 12 on the buffer member 11 and the connecting rod assembly 2.

[0030] like Figure 4 As shown, in one embodiment, the buffer 11 is an integral structure, and / or the buffer 11 is made of any one of silicone material, rubber material, or silicone rubber material.

[0031] In this embodiment, by adopting a one-piece structure for the buffer 11, the assembly process of the buffer 11, which requires splicing between each other during production, is simplified, thus reducing the production cost of the fascia gun 10. The buffer 11 can be made of silicone, rubber, or silicone rubber to ensure that both the buffer 11 and the mounting groove 1111 on the buffer 11 are elastic. During the installation of the buffer 11 and the ball bearing 12, the user needs to apply force to enlarge the opening 1112 of the mounting groove 1111. After the ball bearing 12 is inserted into the mounting groove 1111, the opening 1112 of the mounting groove 1111 elastically recovers and automatically shrinks, thereby installing the ball bearing 12 in the mounting groove 1111, further improving the stability of the connection between the buffer 11 and the ball bearing 12.

[0032] like Figure 4 As shown, in one embodiment, at least a portion of the ball bearings 12 are exposed outside the mounting groove 1111 through the slot 1112, the radius of the slot 1112 being smaller than the radius of the mounting groove 1111.

[0033] In this embodiment, the radius of the slot 1112 is set to be smaller than the radius of the mounting groove 1111, so that the area of ​​the ball 12 exposed in the mounting groove 1111 is not greater than the area located in the mounting groove 1111. This makes it easier for the ball 12 to slide and abut against the connecting rod assembly 2, further improving the stability of the ball 12 rotating in the mounting groove 1111 and preventing the ball 12 from coming out of the mounting groove 1111.

[0034] In one embodiment, the ball 12 is made of plastic material.

[0035] In this embodiment, the production cost of the ball bearing 12 is further reduced by setting it to be made of plastic material. The plastic ball bearing 12 generates less noise when sliding with the connecting rod assembly 2, and the plastic ball bearing 12 is lighter than the metal ball bearing 12, further reducing the overall weight of the fascia gun 10.

[0036] like Figures 1 to 3 As shown, in one embodiment, the linkage assembly 2 further includes a sliding sleeve 21 and a connecting rod 22. The sliding sleeve 21 is sleeved on the outer periphery of the connecting rod 22. The sliding sleeve 21 is located between the connecting rod 22 and the plurality of balls 12, and the sliding sleeve 21 slides against the plurality of balls 12.

[0037] In this embodiment, one end of the connecting rod 22 may have a mounting portion for mounting a massage head. A sliding sleeve 21 is fitted around the outer periphery of the mounting portion, allowing the connecting rod 22 to drive the sliding sleeve 21 to slide axially along the first mounting hole 111. Multiple balls 12 slide and abut against the outer wall of the sliding sleeve 21. This application uses the sliding sleeve 21 to slide and abut against the multiple balls 12, thereby avoiding wear on the connecting rod 22 caused by the balls 12 and further improving the service life of the connecting rod 22. To reduce wear between the sliding sleeve 21 and the balls 12, the sliding sleeve 21 may be made of stainless steel or aluminum alloy to improve its wear resistance.

[0038] like Figure 4 As shown, in one embodiment, the sliding sleeve 21 presses the buffer member 11 through the ball 12 to cause the buffer member 11 to be deformed by compression.

[0039] In this embodiment, the present application uses a sliding sleeve 21 to squeeze the buffer 11 towards the inner wall of the outer shell 101 through the ball 12, so that the buffer 11 undergoes elastic deformation and fits the outer shell 101 better, thereby improving the stability of the connection between the ball 12 and the outer shell 101.

[0040] like Figures 1 to 3 As shown, in one embodiment, the fascia gun 10 further includes a transmission component 4, which is located between the driver 3 and the connecting rod 22. The driver 3 drives the transmission component 4, and the transmission component 4 is connected to the connecting rod 22 in a transmission manner.

[0041] In this embodiment, the application employs a transmission component 4 with one end connected to the connecting rod 22, and the output end of the driver 3 drives the other end of the transmission component 4. The power of the driver 3 is transmitted to the connecting rod 22 through the transmission component 4, making it easier for the driver to drive the connecting rod 22 and the massage head to vibrate. An eccentric shaft may be provided at one end of the transmission component 4 near the connecting rod 22, and the transmission component 4 is connected to one end of the connecting rod 22 through the eccentric shaft.

[0042] like Figures 1 to 3 As shown, in one embodiment, the connecting rod 22 includes a first connecting segment 221 and a second connecting segment 222 connected to each other. The first connecting segment 221 has a second mounting hole 2211 for mounting a massage head, and the second connecting segment 222 has a third mounting hole 2221 on the side opposite to the second mounting hole 2211 for mounting at least a portion of the transmission member 4.

[0043] In this embodiment, the connecting rod 22 can be a one-piece structure, reducing the production cost of the connecting rod 22. The first connecting section 221 has a second mounting hole 2211 for mounting the massage head, and the second connecting section 222 has a third mounting hole 2221 on the side opposite to the second mounting hole 2211 for mounting at least part of the transmission component 4, which makes it easier to install and connect the connecting rod 22 to the massage head and the transmission component 4 respectively.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the first connecting segment 221 is bent relative to the second connecting segment 222, and a clearance space for placing the battery is formed between the first connecting segment 221 and the second connecting segment 222.

[0045] In this embodiment, the connecting rod 22 may include a first connecting segment 221 and a second connecting segment 222 that are connected to each other. The first connecting segment 221 is bent relative to the second connecting segment 222 so that a height difference is formed between the first connecting segment 221 and the second connecting segment 222, thereby forming a clearance space between the first connecting segment 221 and the second connecting segment 222 for placing the battery of the fascia gun 10, thus improving the utilization rate of the internal space of the fascia gun 10.

[0046] like Figures 1 to 3 As shown, in one embodiment, the fascia gun 10 further includes a control component electrically connected to the driver 3, the control component being located on the side opposite to the buffer 11.

[0047] In this embodiment, the control component may include a circuit board 5 and electronic components such as a battery. By electrically connecting the control component to the driver 3, the control component can receive user commands and control the rotational speed of the driver 3, thereby better adjusting the vibration frequency generated by the massage head. The control component is located on the side opposite to the buffer 11, thus preventing damage to the control component caused by vibrations generated by the linkage assembly 2.

[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
