Description

Technical Field

[0001] The utility model relates to the technical field of fascia guns, and particularly relates to a transmission mechanism of a fascia gun and a fascia gun comprising the transmission mechanism. Background Art

[0002] In the prior art, a fascia gun includes a gun body, on which a driving motor, a power supply member, a transmission arm and a massage head are provided. The transmission arm is guided to slide on the gun body. The driving motor can drive the transmission arm to relatively stretch through an eccentric mechanism, and the massage head is arranged on the transmission arm. When the transmission arm stretches, the interface drives the massage head to realize the knocking massage function. The existing assembly method is to open an assembly hole on the transmission arm. Further, a plug-in portion is arranged on the massage head, and the plug-in portion is inserted into the assembly hole to realize the assembly. However, there are at least the following defects: The massage head and the plug-in portion are usually integrally injection-molded. In order to ensure the stability of the connection, it usually needs to be made of a hard material, thereby reducing the comfort. Summary of the Invention

[0003] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a new type of fascia gun. A connecting piece is used to connect the massage head to the transmission arm, which can reduce the hard requirements of the massage head, and customers can disassemble and assemble massage heads with different hardnesses and different styles according to their needs.

[0004] The utility model discloses a transmission mechanism of a fascia gun, which includes a transmission arm and a massage head detachably connected to the transmission arm. The characteristics are as follows: An assembly hole is arranged on the massage head, and a plug-in section extends from one end of the transmission arm facing the massage head. The plug-in section is inserted into the assembly hole, and an anti-detachment structure for restricting the plug-in section from detaching from the assembly hole is further included.

[0005] By adopting the above technical solution, the assembly can be realized by directly inserting the plug-in section on the transmission arm into the assembly hole. At this time, the deforming force will be on the plug-in section, so the hard requirements for the material of the massage head can be reduced. Customers can disassemble and assemble massage heads with different hardnesses and different styles according to their needs, and the anti-detachment structure can further prevent the massage head from detaching, making it more stable during use.

[0006] The further setting of the utility model: The anti-detachment structure includes a connecting piece sleeved on the plug-in section. The connecting piece is also provided with an anti-retreat convex platform arranged in a stepped manner. When the anti-retreat convex platform is inserted into the assembly hole, it can abut against the inner wall of the assembly hole and be tightly fitted.

[0007] By adopting the above technical solution, the cooperation between the anti-retreat convex platform on the connecting piece and the assembly hole can prevent the massage head from being easily pulled out.

[0008] The further setting of the utility model: One end of the connecting piece away from the transmission arm is provided with a knocking plane.

[0009] By adopting the above technical solution, the connecting piece can not only play a connecting role, but also can be directly used as a massage head.

[0010] Further configuration of the utility model: a connecting head is threadedly connected on the plug-in section, and a limiting groove arranged along the axial direction and a clamping groove arranged along the circumferential direction are provided on the connecting head. The connecting head is inserted into the connecting piece, and a limiting block is provided at the position of the limiting groove of the connecting piece, and a clamping block is provided at the position of the clamping groove of the connecting piece. Of course, a threaded hole can also be provided on the connecting piece, and a threaded section can be provided on the plug-in section, so that the plug-in section is directly connected to the connecting piece.

[0011] By adopting the above technical solution, the limit block is arranged in the limit groove to prevent the connecting piece from rotating relative to each other, and the clamping block is arranged in the clamping groove to limit the axial withdrawal of the connecting piece, thereby making it more stable when in use.

[0012] The utility model is further configured as follows: the connecting piece is hollow to form a plug-in cavity, and two openings arranged at intervals are provided on the outer wall of the connecting piece, and the openings extend to be connected to the plug-in cavity so that the side wall of the connecting piece forms a relatively deformable spring sheet, and the clamping block is arranged on the spring sheet.

[0013] By adopting the above technical solution, the spring sheet can be relatively deformed so that the clamping block can smoothly enter the clamping groove, and the spring sheet is formed by the opening of the connecting piece, and its stability is also relatively good.

[0014] A further configuration of the utility model is that the outer side surface of the anti-recession boss is conical.

[0015] By adopting the above technical solution, the conical setting can increase the resistance when pulling out, and further prevent it from automatically separating during use.

[0016] Another purpose of the utility model is to disclose a fascia gun, comprising a gun body, a driving motor arranged on the gun body, an eccentric structure cooperating with the driving motor, and a power supply for supplying power, characterized in that it includes the above-mentioned fascia gun transmission mechanism, the transmission arm is guided and slidable on the gun body, and the transmission arm is connected to the output end of the eccentric structure.

[0026] The following details the specific embodiments of the present utility model with reference to the accompanying drawings:

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. are based on the orientation or positional relationships shown in the accompanying drawings. These are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. Embodiment

[0028] The present disclosure of the utility model relates to a fascia gun transmission mechanism, which includes a transmission arm 1 and a massage head 2 detachably connected to the transmission arm 1. In the embodiment of the present utility model, an assembly hole 21 is provided on the massage head 2, and a plug-in section 3 extends from one end of the transmission arm 1 towards the massage head 2. The plug-in section 3 is inserted into the assembly hole 21, and an anti-disengagement structure for restricting the plug-in section 3 from disengaging from the assembly hole 21 is further included.

[0029] Adopting the above technical solution, the assembly can be achieved by directly inserting the plug-in section 3 on the transmission arm 1 into the assembly hole 21. At this time, the deforming force will act on the plug-in section 3, so the hardness requirement for the material of the massage head 2 can be reduced. Customers can disassemble and assemble massage heads of different hardnesses and different styles according to their needs, and the anti-disengagement structure can further prevent the massage head 2 from disengaging, making it more stable during use.

[0030] The anti - detachment structure includes an adapter 41 sleeved on the insertion section 3. The adapter 41 is also provided with an anti - withdrawal boss 42 arranged in a stepped manner. When the anti - withdrawal boss 42 is inserted into the assembly hole 21, it can abut against and be tightly fitted with the inner wall of the assembly hole 21. By the cooperation of the anti - withdrawal boss 42 on the adapter 41 and the assembly hole 21, the massage head 2 can be prevented from being easily pulled out, and the hard requirements for the massage head 2 are relatively low by using the tight - fitting method.

[0031] One end of the adapter 41 away from the transmission arm 1 is provided with a knocking plane 43, so that the adapter 41 can not only play a connecting role, but also be directly used as a massage head.

[0032] A connector 5 is threadedly connected to the insertion section 3. The connector 5 is provided with an axially - arranged limiting groove 51 and a circumferentially - arranged clamping groove 52. The connector 5 is inserted on the adapter 41. The adapter 41 is provided with a limiting block 411 corresponding to the position of the limiting groove 51, and the adapter 41 is provided with a clamping block 412 corresponding to the position of the clamping groove 52. Of course, it can also be that the adapter 41 is provided with a threaded hole and the insertion section 3 is provided with a threaded section, so that the insertion section 3 is directly connected to the adapter 41. By arranging the limiting block 411 in the limiting groove 51, the relative rotation of the adapter 41 can be prevented, and by arranging the clamping block 412 in the clamping groove 52, the axial pulling - out of the adapter 41 can be restricted, so that it is more stable during use.

[0033] The adapter 41 is hollow - formed to form an insertion cavity 413. Two spaced - apart openings are formed on the outer wall of the adapter 41, and the openings extend to communicate with the insertion cavity 413, so that elastic pieces 414 that can be deformed relatively are formed on the side wall of the adapter 41. The clamping block 412 is arranged on the elastic piece 414. The elastic piece 414 can be deformed relatively so that the clamping block 412 can smoothly enter the clamping groove 52, and the elastic piece 414 is formed by the opening of the adapter 41, and its stability is also relatively good.

[0034] The outer side surface of the anti - withdrawal boss 42 is arranged in a conical shape. The conical arrangement can increase the resistance during pulling out and further prevent automatic separation during use. Embodiment
