Description

Technical Field

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

[0002] A novel fascia gun massage head structure, published on December 31, 2021, with announcement number CN215350563U, describes a structure that, through the setting of a fixing mechanism, extends the connecting column into the interior of the mounting groove and fits against the sealing block. Then, a servo motor is started to drive the winding reel to rotate and loosen the pull rope. Under the tension of the spring, the U-shaped rod is pushed. With the support of the sliding groove and the slider, the movement trajectory of the U-shaped rod is more stable, allowing the U-shaped rod to extend into the interior of the slot, thereby fixing the connecting column and achieving the purpose of a tight connection that is not easy to loosen.

[0003] However, the fixing mechanism of this massage head has many parts, which not only makes production and assembly troublesome, but also requires the corresponding fixing mechanism to be set when different shaped massage heads need to be replaced, which greatly increases the production cost. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a new type of massage head connection structure and massager, so as to solve the problem that the existing massage head fixing mechanism has too many parts, which not only makes assembly troublesome but also has high production costs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel massage head connection structure, comprising:

[0006] A connector, one end of which is open, and the inner wall of the opening is provided with internal threads;

[0007] The massage head has a fixing part at one end, and the outer surface of the fixing part has an external thread that matches the internal thread.

[0008] Preferably, a rubber ring is provided between the massage head and the connector. The rubber ring includes a sealing part and a first protrusion. The outer surface of the sealing part has a first protrusion protruding from it, and the outer edge of the first protrusion is larger than the opening size of the connector.

[0009] Preferably, the end face of the massage head facing the fixing part is larger than the end face of the fixing part, and the rubber ring further includes a second protrusion, the outer edge of the second protrusion being larger than the outer edge of the first protrusion, and the second protrusion being located between the massage head and the first protrusion.

[0010] Preferably, the second protrusion is fitted to the end face of the massage head opposite the fixing part.

[0011] Preferably, the hardness of the rubber ring is 40 to 60 degrees.

[0012] Preferably, the number of turns of the external thread is 1.5 to 2 turns, and the number of turns of the internal thread is not less than the number of turns of the external thread.

[0013] A massager includes a handheld part connected to a housing, a connector movably connected to the housing, and a drive mechanism disposed within the housing, the drive mechanism being driven to the massage head connection structure.

[0014] Preferably, the drive mechanism includes a motor and a cam structure, the motor is fixed inside the housing, the output end of the motor is fixedly connected to the cam structure, and the cam structure is fixedly connected to the connecting member.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0016] This invention utilizes the cooperation of the external thread on the outer surface of the fixing part and the internal thread of the connector to allow the fixing part to gradually enter the opening of the connector, thereby completing the rapid assembly and fixing of the fixing part, i.e., the massage head. Compared with the existing fixing mechanism of the massage head, it greatly reduces the number of parts, thus significantly reducing production costs. The structure is simple, and production and assembly are simple and quick. When it is necessary to replace the massage head with a different shape, only the corresponding massage head needs to be threaded. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0022] like Figure 2 and Figure 3 As shown, this utility model provides a novel massage head connection structure, including a connector 3 and a massage head 2;

[0023] One end of the connector 3 is open, and the inner wall of the opening is provided with an internal thread 31;

[0024] One end of the massage head 2 is provided with a fixing part 21, and the outer surface of the fixing part 21 is provided with an external thread 22 that is compatible with the internal thread 31.

[0025] When it is necessary to assemble the massage head 2, align the fixing part 21 of the massage head 2 with the opening of the connector 3, insert it and screw it in. With the cooperation of the external thread 22 and the internal thread 31, the fixing part 21 gradually enters the opening of the connector 3, thereby completing the quick assembly and fixing of the fixing part 21, i.e., the massage head 2. Compared with the existing fixing mechanism of the massage head 2, the number of parts is greatly reduced, thereby greatly reducing the production cost. The structure is simple and the production and assembly are simple and quick. When it is necessary to replace the massage head 2 with a different shape, only the external thread 22 needs to be opened for the corresponding replacement massage head 2.

[0026] like Figure 2 and Figure 3 As shown, a rubber ring 4 is provided between the massage head 2 and the connector 3. The rubber ring 4 includes a sealing part 41 and a first protrusion 42. The outer surface of the sealing part 41 is provided with the first protrusion 42. The outer edge of the first protrusion 42 is larger than the opening size of the connector 3.

[0027] By setting the first protrusion 42 of such size to be interference-fitted with the connector 3, when the fixing part 21 is fixedly installed in the opening of the connector 3, the thread plays a double fixing role, making the two more stable and the massage head 2 more stable and less likely to fall off.

[0028] like Figure 2 and Figure 3 As shown, the end face of the massage head 2 facing the fixing part 21 is larger than the end face of the fixing part 21. The rubber ring 4 also includes a second protrusion 43. The outer edge of the second protrusion 43 is larger than the outer edge of the first protrusion 42. The second protrusion 43 is located between the massage head 2 and the first protrusion 42.

[0029] The second protrusion 43, as designed in this way, can seal the opening of the connector 3, preventing impurities from entering the opening of the connector 3, and at the same time preventing the massage head 2 and the connector 3 from directly contacting and causing wear when the knob is used to fix the massage head 2.

[0030] Furthermore, the second protrusion 43 is fitted to the end face of the massage head 2 opposite to the fixing part 21. With this arrangement, when the massage head 2 is fixed by the knob, both ends of the second protrusion 43 abut against the connector 3 and the end face of the massage head 2 respectively, so that when the second protrusion 43 is compressed, it plays a certain pre-tightening role.

[0031] like Figure 3 As shown, the hardness of the rubber ring 4 is 40 to 60 degrees. When the hardness of the rubber ring 4 is less than 40 degrees, it is easy to be compressed and the rubber ring 4 is easy to expand during the assembly of the massage head 2. When the hardness of the rubber ring 4 is greater than 60 degrees, it is difficult to screw the rubber ring 4 into the opening of the connector 3, making the assembly of the rubber ring 4 difficult.

[0032] like Figure 3 As shown, the number of turns of the external thread 22 is 1.5 to 2 turns, and the number of turns of the internal thread 31 is not less than the number of turns of the external thread 22. When a second protrusion 43 is required, the number of turns of the internal thread 31 is more than the number of turns of the external thread 22. When a second protrusion 43 is not required, the number of turns of the internal thread 31 can be equal to the number of turns of the external thread 22, thus avoiding unnecessary machining of the internal thread 31.

[0033] By setting the number of external threads 22 within this range, the fixing part 21 and the connecting part 3 can be fixed tightly, while avoiding the need for too many external threads 22, thus improving processing efficiency and reducing processing costs. When the number of external threads 22 is less than 1.5, the fixing part 21 and the connecting part 3 will not be fixed tightly. When the number of external threads 22 is greater than 2, it will result in unnecessary processing of the external threads 22, reducing production efficiency.

[0034] like Figure 1 As shown, a massager (taking a fascia gun as an example in the figure) includes a handheld part 7, which is connected to a housing 1. A connector 3 is movably connected to the housing 1. A drive mechanism is provided inside the housing 1, and the drive mechanism is connected to the massage head 2 connection structure.

[0035] Specifically, such as Figure 2 As shown, the drive mechanism includes a motor 5 and a cam structure 6. The motor 5 is fixed inside the housing 1, and the output end of the motor 5 is fixedly connected to the cam structure 6 (the specific cam structure 6 is an existing structure and will not be described in detail here). The cam structure 6 is fixedly connected to the connecting piece 3.

[0036] The drive motor 5 drives the cam structure 6 to move, and the cam structure 6 drives the connecting piece 3 to reciprocate within the housing 1. The connecting piece 3 is fixed to the fixing part 21 of the massage head 2, thereby driving the massage head 2 to perform reciprocating tapping massage.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
