A connection structure of a fascia gun and a massage head

Abstract

This utility model discloses a connection structure between a fascia gun and a massage head, including two threads on the massage head and two threaded grooves on the fascia gun that mate with the threads. The two threads and the two corresponding threaded grooves rotate 180° symmetrically, allowing the massage head to be screwed into the fascia gun in both directions. Through the connection structure provided by this utility model, the 180° symmetrically rotating double threads and double threaded grooves on the fascia gun and massage head not only allow the massage head to be screwed into the double threaded grooves inside the fascia gun in both directions, but also, especially when using a U-shaped massage head, ensures that the two maintain a vertical or horizontal angle regardless of the assembly direction, resulting in good consistency. This solves the problem of large directional angle deviations during massage head use, reduces installation time, and improves the tightness and reliability of the massage head mounted on the fascia gun. It can withstand insertion and extraction forces greater than 50N, greatly improving the reliability of the fascia gun during use.

Description

Technical Field

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

[0002] Fascial guns primarily work by reciprocating the massage head to impact specific parts of the body. This can relax muscles, relieve fatigue, clear meridians, balance yin and yang, and regulate bodily functions. Massage devices are convenient and effortless, making them increasingly popular.

[0003] However, the massage heads and fascia guns currently available on the market are installed using a snap-fit ​​or single-thread screw-in method, which does not provide a strong connection and is prone to loosening. They are also difficult to install and are easily damaged during use, affecting the use of the fascia gun.

[0004] In view of this, it is necessary to propose further improvements to the current connection structure between the fascia gun and the massage head. Utility Model Content

[0005] Therefore, the purpose of this utility model is to at least partially address the shortcomings of the prior art, thereby proposing a connection structure between a fascia gun and a massage head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a connection structure for a fascia gun and a massage head, applicable to a detachably connected fascia gun and a massage head. It includes two threads on the massage head and two threaded grooves on the fascia gun that are adapted to the two threads. The two threads and the two corresponding threaded grooves rotate 180° symmetrically, so that the massage head can be screwed into the fascia gun in both directions.

[0008] Furthermore, the length of the thread pitch ranges from 20 to 28 mm, and the width ranges from 2.5 to 2.8 mm.

[0009] Furthermore, the massage head is detachably connected to the fascia gun via a connector, and the two threads are symmetrically rotated 180° on the connector.

[0010] Furthermore, the fascia gun is detachably connected to the connector via a piston that can reciprocate relative to it, and the inner wall of the piston is also provided with two threaded grooves that correspond to the two threads and rotate 180° symmetrically.

[0011] Furthermore, the outer side wall of the connector is provided with two symmetrically arranged guide surfaces, which divide the connector into a first connecting part and a second connecting part. The two sides of the first connecting part and the second connecting part are connected by the two guide surfaces respectively.

[0012] Furthermore, the two threads are respectively disposed on the first connecting part and the second connecting part, and the threads on the first connecting part can be rotated 180° along the plane of symmetry of the connector to coincide with the threads on the second connecting part.

[0013] Furthermore, a sealing element is fitted onto the connector, and when the connector is inserted into the piston, the sealing element and the piston abut against each other.

[0014] Furthermore, the materials of the seals are all silicone or rubber.

[0015] This utility model provides a connection structure for a fascia gun and a massage head, applicable to a detachably connected fascia gun and massage head. It includes two threads on the massage head and two threaded grooves on the fascia gun that mate with the threads. The two threads and the two corresponding threaded grooves rotate 180° symmetrically, allowing the massage head to be screwed into the fascia gun in both directions. This connection structure, with its 180° symmetrically rotating double threads and double threaded grooves on both the fascia gun and massage head, allows the massage head to be screwed into the double threaded grooves inside the fascia gun in both directions. Especially when using a U-shaped massage head, it ensures that the fascia gun and massage head maintain a vertical or horizontal angle regardless of the assembly direction, resulting in good consistency. This solves the problem of large directional angle deviations during massage head use, reduces installation time, and improves the tightness and reliability of the massage head mounted on the fascia gun. It can withstand insertion and extraction forces greater than 50N, significantly improving the reliability of the fascia gun during use. Attached Figure Description

[0025] Please refer to Figures 1 to 5 This utility model provides a connection structure between a fascia gun and a massage head, which is applied to a detachably connected fascia gun 1 and a massage head 2. It includes two threads 211 on the massage head 2 and two threaded grooves 111 on the fascia gun 1 that are adapted to the two threads 211. The two threads 211 and the two corresponding threaded grooves 111 rotate symmetrically at 180° so that the massage head 2 can be screwed into the fascia gun 1 in both directions.

[0026] In this embodiment, the connecting structure is applied to the fascia gun 1 and the massage head 2, and the massage head 2 is detachably connected to the fascia gun 1 through the connecting structure. The connecting structure includes two threads 211 and two threaded grooves 111. The two threads 211 are adapted to the two threaded grooves 111, allowing the threads 211 to be screwed into the threaded grooves 111 to fix the massage head 2 to the fascia gun 1. Specifically, the two threads 211 are provided on the massage head 2, and the two threaded grooves 111 are provided on the fascia gun 1, so that the two threads 211 on the massage head 2 can be screwed into the two threaded grooves 111 on the fascia gun 1 that are adapted to it.

[0027] Specifically, the two threads 211 rotate 180° symmetrically, and the two threaded grooves 111 also rotate 180° symmetrically. Each thread 211 corresponds to one threaded groove 111, meaning one thread 211 corresponds to one threaded groove 111. Since the thread 211 is helical, the threaded groove 111 is also helical. This allows the massage head 2 to be screwed into the two 180° symmetrically rotated threaded grooves 111 of the fascia gun 1 in both directions via the two 180° symmetrically rotated threads 211. In other words, the massage head 2 can be screwed into the fascia gun 1 in either clockwise or counterclockwise direction. Regardless of the direction of assembly, the massage head 2 maintains a vertical or horizontal angle with the fascia gun 1, ensuring good consistency. Existing U-shaped massage heads have a large angular deviation when assembled into the fascia gun 1, but the connection structure provided in this embodiment solves this problem. Furthermore, the existing connection between the massage head 2 and the fascia gun 1 is usually not very stable and the installation time is relatively long. The fixing device provided by the embodiment of this application greatly improves the tightness of the two by screwing the fascia gun 1 and the massage head 2 together, so that the fascia gun 1 and the massage head 2 can withstand an insertion and extraction force of more than 50N, and the installation time is reduced.

[0028] The fascia gun 1 can be fitted with different massage heads 2, and the specific internal structure of the fascia gun 1 and the massage head 2 is the same as that of the existing structures on the market, so it will not be elaborated here.

[0029] Furthermore, the length of the thread pitch of thread 211 ranges from 20 to 28 mm, and the width ranges from 2.5 to 2.8 mm.

[0030] In this embodiment, the thread 211, with a pitch ranging from 20 to 28 mm and a width ranging from 2.5 to 2.8 mm, is larger than the threads on existing massage heads. This solves the problems of ordinary single-thread small-pitch assembly requiring only one-way screwing, resulting in excessive installation time and easy damage to the threads on the massage head 2 during use. Furthermore, the thread pitch of the thread 211 in this embodiment is specifically 25 mm in length and 2.6 mm in width, which is a larger pitch than the threads on existing ordinary massage heads. The pitch of the thread 211 is adapted to the size of the threaded groove 111.

[0031] Furthermore, the massage head 2 is detachably connected to the fascia gun 1 via a connector 21, with two threads 21 180° symmetrically rotated on the connector 21.

[0032] In this embodiment, the massage head 2 is detachably connected to the fascia gun 1 via a connector 21, and the connector 21 is provided with two threads 211 that are 180° rotationally symmetrical, so that it can be screwed into the fascia gun 1 in both directions.

[0033] Furthermore, the fascia gun 1 is detachably connected to the connector 21 via a piston 11 that can reciprocate relative to it. The inner wall of the piston 11 is also provided with two threaded grooves 111 that correspond to the two threads 211 and rotate 180° symmetrically.

[0034] In this embodiment, a piston 11 is provided on the fascia gun 1. The inner sidewall of the piston 11 is provided with two threaded grooves 111 that rotate 180° symmetrically. The two threaded grooves 111 are adapted to the threaded threads 211, and the two threaded threads 211 correspond one-to-one with the two threaded grooves 111, so that the threaded threads 211 can be screwed into the threaded grooves 111, thereby allowing the massage head 2 to be screwed into the fascia gun 1 clockwise or counterclockwise.

[0035] Furthermore, two symmetrically arranged guide surfaces 212 are provided on the outer side wall of the connector 21. The two guide surfaces 212 divide the connector 21 into a first connecting part and a second connecting part. The two sides of the first connecting part and the second connecting part are connected by the two guide surfaces 212 respectively.

[0036] In this embodiment, two guide surfaces 212 are provided on the outer side wall of the connector 21. The two guide surfaces 212 are planar and symmetrically arranged. The structural dimensions of the two guide surfaces 212 are the same. The connector 21 can be divided into a first connecting part and a second connecting part through the two symmetrically arranged guide surfaces 212. The two sides of the first connecting part and the second connecting part are respectively connected by a guide surface 212.

[0037] The first end of the thread 211 on the first connecting part corresponds to the tail end of the thread 211 on the second connecting part, and there is a guide surface 212 between them. The first end of the thread 211 on the second connecting part corresponds to the tail end of the thread 211 on the first connecting part, and there is another guide surface 212 between them.

[0038] Furthermore, two threads 211 are respectively provided on the first connecting part and the second connecting part. The threads 211 on the first connecting part can be rotated 180° along the plane of symmetry of the connector 21 to coincide with the threads 211 on the second connecting part.

[0039] In this embodiment, two threads 211 are respectively disposed on the first connecting portion and the second connecting portion. The threads 211 on the first connecting portion can be rotated 180° along the symmetry plane of the connector 21 to coincide with the threads 211 on the second connecting portion, thereby allowing the two threads 211 to rotate symmetrically. The axes of symmetry of the two guide surfaces 212 are along the rotation direction of the threads, and the axes of symmetry of the two guide surfaces 212 coincide with the symmetry plane of the connector 21, that is, the two axes of symmetry are disposed on the symmetry plane of the connector 21. In this embodiment, the connector 21 is cylindrical.

[0040] Furthermore, a sealing element 213 is fitted onto the connector 21. When the connector 21 is inserted into the piston 11, the sealing element 213 and the piston 11 are in contact.

[0041] In this embodiment, the connector 21 is provided with a sealing element 213. When the connector 21 on the massage head 2 is inserted into the piston 11 of the fascia gun 1, the sealing element 213 and the piston 11 are abutted together. The sealing element 213 can play a role in sealing and shock absorption, preventing dust, sweat, hair and other substances from entering the interior, avoiding short circuits or mechanical jamming, and absorbing some vibration energy through the elastic deformation of the sealing element, reducing the vibration transmitted from the handle or body to the user's hand and reducing fatigue.

[0042] The material of the seal 213 is silicone or rubber.

[0043] This utility model provides a connection structure for a fascia gun and a massage head, applicable to a detachably connected fascia gun and massage head. It includes two threads on the massage head and two threaded grooves on the fascia gun that mate with the threads. The two threads and the two corresponding threaded grooves rotate 180° symmetrically, allowing the massage head to be screwed into the fascia gun in both directions. This connection structure, with its 180° symmetrically rotating double threads and double threaded grooves on both the fascia gun and massage head, allows the massage head to be screwed into the double threaded grooves inside the fascia gun in both directions. Especially when using a U-shaped massage head, it ensures that the fascia gun and massage head maintain a vertical or horizontal angle regardless of the assembly direction, resulting in good consistency. This solves the problem of large directional angle deviations during massage head use, reduces installation time, and improves the tightness and reliability of the massage head mounted on the fascia gun. It can withstand insertion and extraction forces greater than 50N, significantly improving the reliability of the fascia gun during use.
