一种筋膜枪的传动结构及筋膜枪

Abstract

本实用新型公开了一种筋膜枪的传动结构及筋膜枪，筋膜枪的传动结构，包括：主动件，主动件与驱动件的输出端连接；从动组件，从动组件上设置有与主动件啮合的柔性结合部；连接杆，连接杆的一端与从动组件的偏心轴连接，连接杆的另一端与筋膜枪的按摩头连接；驱动件驱动主动件与从动组件联动，并通过连接杆带动按摩头做往复直线运动。本实用新型中从动组件上的柔性结合部在与主动件啮合传动时，能有效缓冲啮合过程中的冲击力，减轻动力传动过程中的振动，从而减小噪声和冲击感；同时，柔性结合部还能通过自适应补偿主动件与从动组件之间的装配间隙，以通过形变使得两者实现紧密啮合，提升传动平稳性和运行可靠性，延长筋膜枪的使用寿命。

2. The transmission structure of the fascia gun according to claim 1, wherein, The driving component is a bevel gear; the flexible joint is a bevel tooth.

3. The transmission arrangement of claim 2, wherein, The driven component includes a driven member and a rotating member. The flexible joint is located on the driven member. The driven member at least partially covers the rotating member, and the driven member and the rotating member are synchronously rotatably connected. The eccentric shaft is located on the rotating member.

4. The transmission structure of the fascia gun according to claim 3, characterized in that, The driven member has a wrapping portion extending on its end face opposite to the flexible joint portion, which at least partially covers the rotating member; the main body of the wrapping portion is provided with a first joint portion, and the rotating member is provided with a second joint portion that engages with the first joint portion.

5. The transmission structure of the fascia gun according to claim 4, characterized in that, The driven member has a third connecting part on the side end face of the package portion, and the package portion is located outside the third connecting part. The rotating member has a fourth connecting part that is inserted and engaged with the third connecting part.

6. The transmission structure of the fascia gun according to claim 1, wherein, The driven component has a first buffer member sleeved on its eccentric shaft. The base of the first buffer member has a first through hole for the eccentric shaft to pass through. One end of the connecting rod has a first pivot hole for the elastic arm of the first buffer member to be inserted. The elastic arm of the first buffer member extends axially from the base of the first buffer member toward the first through hole. The driving component drives the active component and the driven component to move in linkage, and drives the connecting rod to perform reciprocating linear motion. The eccentric shaft causes the elastic arm of the first buffer component to deform.

7. The transmission structure of the fascia gun according to claim 6, characterized in that, A mounting groove communicating with the first pivot hole is provided on the periphery of the first pivot hole. The elastic arm of the first buffer is inserted into the mounting groove, and at least part of the elastic arm of the first buffer is located in the first pivot hole. Under normal conditions, the elastic arm of the first buffer creates a gap between the eccentric shaft and the inner wall of the first pivot hole.

8. The transmission structure of the fascia gun according to claim 6, characterized in that, The transmission structure of the fascia gun also includes a sleeve assembly, a second buffer, and a pivot shaft. The other end of the connecting rod is connected to the sleeve assembly via the pivot shaft, and the second buffer is clamped between the other end of the connecting rod and the sleeve assembly. The base of the second buffer member is provided with a second through hole for the pivot shaft to pass through, and the other end of the connecting rod is provided with a second pivot hole for the elastic arm of the second buffer member to be inserted. The elastic arm of the second buffer member extends axially from the base of the second buffer member toward the second through hole. The driving member drives the active member and the driven member to move together and drive the connecting rod to perform reciprocating linear motion. The pivot shaft causes the elastic arm of the second buffer member to deform.

9. The transmission structure of the fascia gun according to claim 3, characterized in that, The driven member and the rotating member are integrally formed.

10. A fascia gun, characterized in that, The device includes a housing, within which a mounting bracket and a transmission structure for a fascia gun as described in any one of claims 1-9 are provided. The mounting bracket is provided with a mounting seat, and the mounting seat is provided with a bearing for supporting the rotation of the driven component.
