Description

Technical Field

[0001] The utility model relates to the field of massage equipment, in particular to a connection structure between a massage head and a fascia gun. Background Art

[0002] The fascia gun is a massage tool used to help soft tissue rehabilitation. The fascia gun uses its internal motor to drive the massage head, generating high-frequency vibrations that act on the deep layers of the human body's soft tissues, thereby reducing local soft tissue tension, relieving pain, and promoting blood circulation.

[0003] Depending on the massage area, a fascia gun is usually equipped with multiple different massage heads, so the massage head and the fascia gun main unit are usually set up in a quick-detachable connection mode for easy replacement. The products currently on the market usually set an inner hole on the push rod of the fascia gun, and set a soft rubber ring on the support rod of the massage head. Then, when connecting the massage head and the fascia gun main unit, the massage head support rod is manually inserted into the inner hole on the push rod, so that the soft rubber ring on the support rod forms an interference fit with the inner hole, thereby clamping the support rod in the inner hole to achieve a quick connection between the massage head and the fascia gun main unit. When removing the massage head from the fascia gun main unit, the massage head can be directly and quickly pulled out by hand. Although this method can achieve quick connection and disassembly of the massage head and the fascia gun host, when the massage head support rod is inserted into the inner hole of the push rod, the outer edge of the inner hole will scratch the soft rubber ring. After multiple installations, the soft rubber ring will be worn, which will cause insufficient interference fit between the soft rubber ring and the inner hole, resulting in the connection between the massage head and the fascia gun host being not stable and firm enough, causing the massage head to shake left and right or even fall off during the use of the fascia gun. In addition, the massage head is often in direct contact with the skin, is easy to get dirty, and needs to be cleaned regularly. The soft rubber ring set on the massage head support rod will also increase the difficulty of cleaning the massage head. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a connection structure between a massage head and a fascia gun, so that the massage head and the fascia gun host can be stably connected and quickly disassembled.

[0005] The technical solution of the utility model is: a massage head and a fascia gun connection structure, comprising a push rod assembly and a massage head, the push rod assembly comprising a push rod sleeve, a connecting rod soft rubber and a connecting rod, the push rod sleeve, the connecting rod soft rubber and the connecting rod are sleeved in sequence, the connecting rod soft rubber is sleeved outside the connecting rod, the push rod sleeve is sleeved outside the connecting rod soft rubber, a limiting piece is provided on one end of the connecting rod, the massage head is provided with a cavity, the inner wall of the cavity is provided with a guide groove and a limiting groove that can cooperate with the limiting piece, when the massage head is connected to the push rod assembly, the push rod assembly is inserted into the cavity so that the limiting piece enters the guide groove, when the limiting piece reaches the bottom of the guide groove, the massage head or the push rod assembly is rotated so that the limiting piece enters the limiting groove to lock the massage head and the push rod assembly.

[0006] Specifically, a circle of annular protrusions is provided on the soft rubber of the connecting rod. When the massage head is connected to the push rod assembly, after the limiting member enters the guide groove, the annular protrusion is squeezed by the massage head and the push rod sleeve to undergo elastic deformation. The elastic force generated by the elastic deformation causes the massage head and the push rod assembly to tend to separate, thereby causing the limiting member and the limiting groove to press against each other along the axial direction of the connecting rod to further lock the massage head and the push rod assembly.

[0007] Specifically, an annular flange is provided on the side of the annular protrusion close to the limiting member.

[0008] Specifically, the limiting groove includes a depression and an elastic protrusion, the elastic protrusion is arranged on a side of the depression close to the guide groove, the side of the elastic protrusion close to the guide groove is an inclined surface, the limiting member includes a first protrusion and a second protrusion spaced apart and arranged along the axial direction of the connecting rod, when the massage head is connected to the push rod assembly, after the limiting member reaches the bottom of the guide groove, the massage head or the push rod assembly is rotated, the first protrusion enters the depression, the elastic protrusion is stuck between the first protrusion and the second protrusion to fix the massage head and the push rod assembly, or the first protrusion and the second protrusion enter the depression together, the elastic protrusion blocks the first protrusion and the second protrusion in the depression to fix the massage head and the push rod assembly.

[0009] Specifically: the limiting member is a wedge-shaped protrusion, and the limiting groove is a wedge-shaped groove that can cooperate with the wedge-shaped protrusion. When the massage head is connected to the push rod assembly, after the limiting member reaches the bottom of the guide groove, the massage head or the push rod assembly is rotated to make the wedge-shaped protrusion and the wedge-shaped groove move toward each other. After the wedge-shaped protrusion and the wedge-shaped groove move toward each other to a certain position, an interference fit is formed between the two to achieve locking of the massage head and the push rod assembly.

[0010] Specifically, an elastic arm hook is provided at one end of the connecting rod away from the limiting member, and a groove which can cooperate with the elastic arm hook is provided on the inner wall of the push rod sleeve.

[0011] Specifically, a plurality of convex rings are provided on the outer wall of the connecting rod at a side away from the limiting member.

[0012] Specifically, a DC power supply male terminal component is fixedly arranged in the inner cavity of the connecting rod, and a DC power supply female terminal component is fixedly arranged in the cavity of the massage head.

[0013] The utility model embodiment provides a massage head and fascia gun connection structure, including a push rod assembly and a massage head with a cavity. When connecting the massage head to the fascia gun main unit, first insert the push rod assembly into the cavity of the massage head so that the limit piece reaches the bottom of the guide groove, and then rotate the massage head or the push rod assembly so that the limit piece enters the limit groove to lock the massage head and the push rod assembly. In addition, the elastic force generated by the elastic deformation of the annular protrusion causes the massage head and the push rod assembly to tend to separate, so that the limit piece and the limit groove are pressed together along the axial direction of the connecting rod to further lock the massage head and the push rod assembly. In this way, the massage head can be stably and firmly connected to the fascia gun main unit. When the fascia gun is used, the massage head will not shake left and right or even fall off. The massage head and the fascia gun main unit can also be quickly connected and disassembled, and the massage head is also easier to clean after being removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] like Figure 1-3 As shown, a massage head and fascia gun connection structure provided by an embodiment of the utility model comprises a push rod assembly 1 and a massage head 2, the push rod assembly 1 comprises a push rod sleeve 11, a connecting rod soft rubber 12 and a connecting rod 13, the push rod sleeve 11, the connecting rod soft rubber 12 and the connecting rod 13 are sleeved in sequence, the connecting rod soft rubber 12 is sleeved outside the connecting rod 13, the push rod sleeve 11 is sleeved outside the connecting rod soft rubber 12, a limiting piece 131 is provided on one end of the connecting rod 13, a cavity 21 is provided on the massage head 2, a guide groove 22 and a limiting groove 23 which can cooperate with the limiting piece 131 are provided on the inner wall of the cavity 21, when the massage head 2 is connected to the push rod assembly 1, the push rod assembly 1 is inserted into the massage head 2, and the massage head 2 is connected to the push rod assembly 1. When the massage head 2 and the push rod assembly 1 are disassembled, the massage head 2 or the push rod assembly 1 is rotated in the opposite direction to make the limit member 131 withdraw from the limit slot 23 and enter the guide slot 22, and then the push rod assembly 1 is pulled out of the cavity 2. In this way, the massage head 2 and the push rod assembly 1 can be quickly connected and disassembled, and the massage head 2 and the push rod assembly 1 can be more firmly and stably connected. In addition, the massage head 2 is also easier to clean.

[0021] like Figure 4 As shown, specifically, a circle of annular protrusions 121 is provided on the soft rubber 12 of the connecting rod. When the massage head 2 is connected to the push rod assembly 1, after the limiting member 131 enters the guide groove 22, the annular protrusion 121 is squeezed by the massage head 2 and the push rod sleeve 11 to undergo elastic deformation. The elastic force generated by the elastic deformation causes the massage head 2 and the push rod assembly 11 to tend to separate, thereby causing the limiting member 131 and the limiting groove 23 to press axially along the connecting rod 13 to further lock the massage head 2 and the push rod assembly 1. This can make the connection between the massage head 2 and the push rod assembly 1 more stable and firm, and prevent the massage head 2 from shaking left and right or even falling off the push rod assembly 1 during use.

[0022] like Figure 4 As shown, specifically, an annular flange 1211 is provided on the side of the annular protrusion 121 close to the limiter 131, so that when the massage head 2 is connected to the push rod assembly 1, the friction between the annular protrusion 121 and the massage head will not be too large, making it easier to rotate the massage head 2 or the push rod assembly 1.

[0023] like Figure 1-3As shown, specifically, the limiting groove 23 includes a recess 231 and an elastic protrusion 232, the elastic protrusion 232 is arranged on a side of the recess 231 close to the guide groove 22, and the side of the elastic protrusion 232 close to the guide groove 22 is an inclined surface, and the limiting member 131 includes a first protrusion 1311 and a second protrusion 1312 that are spaced and arranged along the axial direction of the connecting rod 13. When the massage head 2 is connected to the push rod assembly 1, after the limiting member 131 reaches the bottom of the guide groove 22, the massage head 2 or the push rod assembly 1 is rotated to make the first protrusion 1311 enter the recess 231. The elastic protrusion 232 is stuck between the first protrusion 1311 and the second protrusion 1312 to fix the massage head 2 and the push rod assembly 1, or the first protrusion 1311 and the second protrusion 1312 enter the recess 231 together, and the elastic protrusion 232 blocks the first protrusion 1311 and the second protrusion 1312 in the recess 231 to lock the massage head and the push rod assembly, which can make the connection between the massage head 2 and the push rod assembly 1 more stable and firm, and can also achieve quick connection and disassembly of the massage head 2 and the push rod assembly 1.

[0024] In other embodiments, the limiting member 131 may also be a wedge-shaped protrusion (not shown), and the limiting groove 23 may be a wedge-shaped groove (not shown) that can cooperate with the wedge-shaped protrusion (not shown). When the massage head 2 is connected to the push rod assembly 1, after the limiting member 131 reaches the bottom of the guide groove 22, the massage head 2 or the push rod assembly 1 is rotated to make the wedge-shaped protrusion (not shown) and the wedge-shaped groove (not shown) move toward each other. After the wedge-shaped protrusion (not shown) and the wedge-shaped groove (not shown) move toward each other to a certain position, an interference fit is formed between the two, thereby achieving locking of the massage head 2 and the push rod assembly 1. In this way, the connection between the massage head 2 and the push rod assembly 1 can be made more stable and firm, and quick connection and disassembly of the massage head 2 and the push rod assembly 1 can also be achieved.

[0025] like Figure 1 As shown, specifically, an elastic arm hook 132 is provided at one end of the connecting rod 13 away from the limiting member 131, and the inner wall of the push rod sleeve 11 is provided with a groove 111 that can cooperate with the elastic arm hook 132. By inserting the elastic arm hook 132 into the groove 111, the connection between the connecting rod 13 and the push rod sleeve 11 can be made more stable and firm.

[0026] Specifically, a plurality of convex rings (not shown) are provided on the outer wall of the connecting rod 13 away from the limiting member 131 , and the convex rings are interference fit with the inner wall of the push rod sleeve 11 , so that the sleeve connection between the connecting rod 13 and the push rod sleeve 11 can be more stable and firm.

[0027] Specifically, a DC power male end assembly (not shown) is fixedly provided in the inner cavity of the connecting rod 13, and a DC power female end assembly (not shown) is fixedly provided in the cavity 21 of the massage head 2. In this way, when the fascia gun host is connected to the massage head 2 through the push rod assembly 1, the massage gun host can supply power to the massage head 2 through the DC power male end assembly and the DC power female end assembly.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
