Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a multi-head fascia gun with a rotatable handle. Background Art

[0002] In the prior art, a multi-head fascia gun includes a shell driving motor, an eccentric mechanism, a mounting bracket and a massage head arranged on the mounting bracket. Handles are arranged on opposite sides of the shell. The driving motor drives the mounting bracket to move relative to each other through the eccentric mechanism, thereby driving the massage head to retract and extend, thereby realizing a tapping massage function. However, the handle of the existing multi-head fascia gun is fixedly arranged on the shell and cannot be rotated and adjusted according to needs, which has limitations when used. Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a multi-head fascia gun with a rotatable handle, which can adjust the handle by rotation through a hinge and lock it after rotation, thereby preventing the handle from shaking relative to the user during use. The utility model is more stable during use and has a more reasonable structural layout.

[0004] The utility model discloses a multi-head fascia gun with rotatable handles, comprising a shell, on which a driving motor, an eccentric structure, a mounting bracket and a massage head arranged on the mounting bracket are arranged. The driving motor can drive the mounting bracket to slide on the shell through the eccentric structure. The utility model is characterized in that handles are rotatably arranged on opposite sides of the shell, and a locking structure for locking the handles after rotation is also arranged at positions corresponding to the handles on the shell.

[0005] By adopting the above technical solution, when in use, the driving motor can drive the mounting bracket to slide in a guided manner through the eccentric structure, thereby driving the massage head to extend and retract to achieve percussion massage, and the handles on both sides can also rotate relative to the shell to achieve angle adjustment. After the adjustment is completed, the locking structure can lock it to prevent it from rotating on its own.

[0006] The utility model is further configured as follows: the locking structure includes a limit shaft that slides axially and circumferentially on the shell and a driving member that drives the limit shaft to slide relatively. A first limit surface is arranged on the handle, and a second limit surface and an avoidance surface are sequentially arranged on the limit shaft along its sliding direction. When the second limit surface on the limit shaft slides to the position of the first limit surface, the second limit surface can be offset against the first limit surface to achieve rotational limitation. When the avoidance surface on the limit shaft slides to the position of the first limit surface, the handle can rotate relative to the avoidance surface.

[0007] By adopting the above technical solution, when angle adjustment is required, the driving member drives the limit shaft to slide axially, so that the second limit surface is separated from the first limit surface, and the first limit surface is in the corresponding avoidance surface position, so that the handle can rotate normally. After the adjustment is completed, the limit shaft is further reset, so that the second limit surface slides to the position of the first limit surface to achieve locking.

[0008] The utility model is further configured as follows: the limiting shaft portion extends into the interior of the handle, a first return spring is provided inside the handle at a position corresponding to the limiting shaft, one end of the first return spring abuts against the handle, and the other end abuts against the limiting shaft, and an abutment plate is provided on the limiting shaft inside the handle, the abutment plate can abut against the handle to achieve displacement limitation of the limiting shaft, the driving member is movably arranged on the shell, and a first inclined extrusion surface is provided on the side of the driving member facing the limiting shaft, and a second inclined extrusion surface matching the first inclined extrusion surface is provided on the side of the limiting shaft facing the first inclined extrusion surface.

[0009] By adopting the above technical solution, when the driving member moves, the first inclined extrusion surface can squeeze the second inclined extrusion surface so that the limit shaft can slide relatively, thereby causing the second limit shaft to separate from the first limit surface. The angle can be further adjusted by turning the handle. After the adjustment is completed, the limit shaft can be driven to slide and reset by the first return spring, so that the second limit surface can automatically slide to the position of the first limit surface, and the abutment plate can prevent the limit shaft from sliding excessively, further improving the stability and preventing the limit shaft from separating from the handle.

[0010] The utility model is further configured as follows: a guide groove is provided on the shell corresponding to the position of the limit shaft, the limit shaft is guided and slidable in the guide groove, and a pressure plate is provided on the top of the shell corresponding to the guide groove, and the pressure plate covers the upper part of the limit shaft.

[0011] By adopting the above technical solution, the guide groove can guide when the limit shaft slides, and the limit is performed by the pressure plate, which can prevent the limit shaft from deviating, and it is relatively stable during assembly and use.

[0012] The utility model is further configured as follows: the driving member is a button, a second return spring is arranged at the bottom of the button, one end of the second return spring abuts against the housing, and the other end abuts against the button.

[0013] By adopting the above technical solution, the first inclined extrusion surface can be driven to squeeze the second inclined extrusion surface by pressing, so that the limit shaft can slide. After completion, the second return spring drives the button to reset, which can facilitate its reciprocating work and reduce the elasticity requirement of the first return spring.

[0014] The utility model is further configured as follows: the handle is a U-shaped handle, both ends of which are hingedly arranged on the housing, and two sets of locking structures are also arranged, which correspond one to one with the ends of the U-shaped handle.

[0015] By adopting the above technical solution, two sets of locking structures are used for locking, which makes it more stable when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings:

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] The utility model discloses a multi-head fascia gun with a rotatable handle, comprising a shell 1, on which a driving motor 2, an eccentric structure 3, a mounting bracket 4 and a massage head 5 arranged on the mounting bracket 4 are arranged. The driving motor 2 can drive the mounting bracket 4 to slide on the shell 1 through the eccentric structure 3. The mounting bracket 4 is provided with a plurality of massage heads 5, which is common knowledge for those skilled in the art and will not be introduced in detail herein. In the implementation case of the utility model, handles 6 are rotatably arranged on opposite sides of the shell 1, and a locking structure 7 for locking the handle after it is rotated is also provided at a position corresponding to the handle 6 on the shell 1.

[0028] By adopting the above technical solution, when in use, the driving motor 2 can drive the mounting bracket 4 to slide in a guided manner through the eccentric structure 3, thereby driving the massage head 5 to extend and retract to achieve percussion massage, and the handles 6 on both sides can also rotate relative to the shell 1 to achieve angle adjustment. After the adjustment is completed, the locking structure 7 can lock it to prevent it from rotating by itself.

[0029] The locking structure 7 includes a limiting shaft 71 that is circumferentially limited and axially slidable on the housing 1, and a driving member 72 that drives the limiting shaft 71 to slide relatively. The handle 6 is provided with a first limiting surface 61, and the limiting shaft 71 is provided with a second limiting surface 711 and an avoidance surface 712 in sequence along its sliding direction (the second limiting surface 711 is most preferably formed by a square segment, or a single limiting plane is used, and the avoidance surface 712 can be formed by a cylindrical segment, or the diameter can be reduced so that the first limiting surface 61 will not be hindered when the handle 6 rotates). When the second limiting surface 711 on the limiting shaft 71 slides to the first When the limiting surface 61 is in the position, the second limiting surface 711 can be offset against the first limiting surface 61 to achieve rotational limit. When the avoidance surface 712 on the limiting shaft 71 slides to the position of the first limiting surface 61, the handle 6 can rotate relative to the avoidance surface 712. When angle adjustment is required, the driving member 72 drives the limiting shaft 71 to slide axially, so that the second limiting surface 711 is separated from the first limiting surface 61, and the first limiting surface 61 corresponds to the position of the avoidance surface 712, so that the handle 6 can rotate normally. After the adjustment is completed, the limiting shaft 71 is further reset, so that the second limiting surface 711 slides to the position of the first limiting surface 61 to achieve locking.

[0030] The limiting shaft 71 partially extends into the interior of the handle 6, and a first return spring 8 is provided in the interior of the handle 6 at a position corresponding to the limiting shaft 71. One end of the first return spring 8 abuts against the handle 6, and the other end abuts against the limiting shaft 71. An abutment plate 713 is provided on the limiting shaft 71 inside the handle 6, and the abutment plate 713 can abut against the handle 6 to limit the displacement of the limiting shaft 71. The driving member 72 is movably arranged on the housing 1, and a first inclined extrusion surface 721 is provided on the side of the driving member 72 facing the limiting shaft 71, and a second inclined extrusion surface 714 matching therewith is provided on the side of the limiting shaft 71 facing the first inclined extrusion surface 721. When the driving member 72 is active, the first inclined extrusion surface 721 is provided on the side of the limiting shaft 71 facing the first inclined extrusion surface 721. The surface 721 can squeeze the second inclined extrusion surface 714 so that the limiting shaft 71 can slide relatively, thereby causing the second limiting surface 711 to separate from the first limiting surface 61. The angle can be further adjusted by rotating the handle 6. After the adjustment is completed, the limiting shaft 71 can be driven to slide and reset through the first return spring 8, so that the second limiting surface 711 can automatically slide to the position of the first limiting surface 61, and the abutment plate 713 can prevent the limiting shaft 71 from sliding excessively, further improving the stability and preventing the limiting shaft 71 from separating from the handle 6. Of course, the limiting shaft 71 can also be connected to the driving member 72 as a whole, and the limiting shaft 71 can be driven to slide by pulling the driving member 72.

[0031] A guide groove 11 is provided on the shell 1 at a position corresponding to the limit shaft 71, and the limit shaft 71 is guided to slide in the guide groove 11, and a pressure plate 9 is also provided on the top of the shell 1 corresponding to the guide groove 11, and the pressure plate 9 covers the top of the limit shaft 71. The guide groove 11 can guide when the limit shaft 71 slides, and the pressure plate 9 is used to limit the limit shaft 71, so that the limit shaft 71 can be prevented from deviating, and it is relatively stable during assembly and use.

[0032] The driving member 72 is a button, and a second return spring 10 is arranged at the bottom of the button. One end of the second return spring 10 is against the shell 1, and the other end is against the button. By pressing, the first inclined extrusion surface 721 can be driven to squeeze the second inclined extrusion surface 714, so that the limit shaft 71 can slide. After completion, the second return spring 10 drives the button to reset, which can facilitate its reciprocating work and reduce the elasticity requirement of the first return spring 8.

[0033] The handle 6 is a U-shaped handle, both ends of which are hingedly arranged on the shell 1. Two sets of locking structures 7 are also provided, and they correspond one to one with the ends of the U-shaped handle. The two sets of locking structures 7 are used for locking, which makes it more stable when used.
