Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, and in particular to a fascia gun with a novel unlocking structure. Background Technology

[0002] Fascia guns primarily stimulate various receptors in muscles, tendons, and joint capsules through high-frequency vibrations. Using a fascia gun to massage the human body can reduce myogenic pain, increase the pain threshold, and reduce lactic acid buildup. Massaging muscles with a fascia gun after exercise can relieve soreness and shorten muscle recovery time.

[0003] A Chinese utility model patent published on January 28, 2025, with publication number CN222399467U, describes a fascia gun with a handle extension function. By setting a bending extension part, when it is necessary to massage any part of a person's back, the massage part can be separated from the handle part first, and then one end of the bending extension part can be fixed to the massage part, and the other end of the bending extension part can be fixed to the handle part. This is equivalent to extending the handle part, thereby effectively expanding the area and range of massage for the user using the fascia gun, avoiding the inconvenience of the user using it when massaging certain muscles or being unable to reach certain massage positions.

[0004] However, the detachable fixing of the handle, massage part and bending extension part of the fascia gun uses a screw-locking and unlocking method, which has the following problems: frequent screwing will cause wear on the threads and limit parts, resulting in a short service life, reduced locking reliability, and even the risk of loosening. Thermal expansion and contraction may cause the screw to be too tight or loose. The screw structure needs to reserve rotation space and requires high precision in product processing. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a fascia gun with a novel unlocking structure to solve the problems that frequent twisting will cause wear on the threads and limiting parts, reduce the reliability of locking, and even cause the risk of loosening. Thermal expansion and contraction may cause the buckle to be too tight or loose. The buckle structure needs to reserve rotation space and has high precision requirements for product processing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fascia gun with a novel unlocking structure, comprising a handle and a massage part, and further comprising:

[0007] A first connecting seat is fixed to one end of the massage part facing the handle part, and at least one slot is provided on the side wall of the first connecting seat.

[0008] The second connecting seat is fixed to the end of the handle that faces the massage part;

[0009] At least one rotating block is rotatably provided on the second connecting seat;

[0010] The rotating block has a locking block on one side that is adapted to the size of the locking slot;

[0011] When the handle and the massage part are connected, the locking block is fixed in the slot by the elastic force of the elastic element.

[0012] Preferably, it further includes a bent extension portion, wherein a first connecting seat and a second connecting seat are respectively provided at both ends of the bent extension portion.

[0013] Preferably, the second connecting seat includes a positioning block and at least one side block, the rotating block is rotatably disposed on the side block, the first connecting seat includes a protrusion facing one end of the second connecting seat, the protrusion has a positioning groove adapted to the positioning block, and the wall thickness between the positioning block and the side block is greater than that of the protrusion.

[0014] Preferably, the elastic element is a torsion spring, the top of the side block has a notch, a rotating rod is rotatably mounted in the notch, a rotating block is fixedly installed on the outer surface of the rotating rod, the torsion spring is sleeved around the rotating rod, one end of the torsion spring abuts against the rotating block, and the other end abuts against the side block.

[0015] Preferably, the notch is provided with a blocking part, and the rotating block is provided with a stop block on the side opposite to the locking block. When the first connecting seat and the second connecting seat are not in contact, the blocking part is in contact with the stop block.

[0016] Preferably, it also includes a pressing member, and the outer surfaces of the handle portion and the bending extension portion are slidably provided with pressing members. When the locking block is located in the locking groove, one end of the pressing member protrudes from the outer surfaces of the handle portion and the bending extension portion. When the pressing member gradually slides into the handle portion or the bending extension portion, the pressing member drives the rotating block to rotate, and the locking block gradually moves away from the locking groove.

[0017] Preferably, the massage part is provided with a transmission mechanism, the handle part is provided with a power source, and the transmission mechanism is connected to the massage head.

[0018] Preferably, when the card block is located in the card slot, the included angle between the rotating block and the first connecting seat is 5°-10°.

[0020] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0021] This utility model employs a rotating block, elastic element, locking block, and locking groove unlocking and locking structure. Compared with existing rotary locking and unlocking mechanisms, it avoids wear on threads and limiting parts caused by frequent turning, improves locking reliability, and has a longer service life. The elastic deformation of the elastic element can prevent the rotary lock from becoming too tight or loose due to thermal expansion and contraction.

[0027] 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.

[0028] like Figures 1-4 As shown, this utility model provides a fascia gun with a novel unlocking structure, including a handle part 1 and a massage part 2, and also includes a first connecting seat 8, a second connecting seat 9, at least one rotating block 6, a locking block 7 and an elastic element 11;

[0029] The first connecting seat 8 is fixed to one end of the massage part 2 facing the handle part 1, and at least one slot 81 is provided on the side wall of the first connecting seat 8;

[0030] The second connecting seat 9 is fixed to one end of the handle part 1 facing the massage part 2;

[0031] At least one rotating block 6 is rotatably provided on the second connecting seat 9;

[0032] A locking block 7, which is adapted to the size of the locking slot 81, is provided on one side of the rotating block 6;

[0033] When the handle part 1 and the massage part 2 are connected, the locking block 7 is fixed in the locking groove 81 by the elastic force of the elastic member 11;

[0034] When it is necessary to connect and fix the handle part 1 and the massage part 2, the rotating block 6 is adjusted to rotate so as not to obstruct the normal docking of the handle part 1 and the massage part 2 (first connecting seat 8 and second connecting seat 9). That is, during the docking of the first connecting seat 8 and the second connecting seat 9, the rotating block 6 and the locking block 7 will not come into contact with or collide with the first connecting seat 8, reducing direct collision and wear. After the handle part 1 and the massage part 2 are docked, the rotating block 6 is adjusted to rotate (here, by the rebound force of the elastic element 11), which drives the locking block 7 to rotate into the locking groove 81 of the first connecting seat 8, thereby locking and fixing the first connecting seat 8 and the second connecting seat 9. Compared with the existing screw-locking and unlocking, it can avoid the wear of threads and limit parts caused by frequent twisting, improve the reliability of locking, and have a longer service life. The elastic deformation of the elastic element 11 can avoid the problem of the screw being too tight or loose due to thermal expansion and contraction. Compared with the existing screw-locking structure, the unlocking structure in this application has lower processing requirements and is simpler to process.

[0035] like Figure 1 and Figure 2 As shown, it also includes a bending extension 3, with a first connecting seat 8 and a second connecting seat 9 respectively provided at both ends of the bending extension 3;

[0036] Similarly, by setting the first connecting seat 8 and the second connecting seat 9 in the bending extension 3, and at least one rotating block 6 on the second connecting seat 9, and a locking block 7 on one side of the rotating block 6 that is adapted to the size of the locking slot 81, the bending extension 3 can be quickly disassembled and fixed to the handle 1 and the massage part 2. Specifically, the bending extension 3 is made of a deformable material, specifically rubber or soft metal (such as a gooseneck tube), so that the bending angle adjustment range of the bending extension 3 is wider, thereby further meeting the massage needs of different people for different parts of the body, reducing discomfort in the movement of the arm joints, and making it more applicable. Specifically, the function and effect of the bending extension 3 are consistent with those in the fascia gun with handle extension function in the announcement number CN222399467U, and will not be repeated here.

[0037] like Figures 2-4As shown, the second connecting seat 9 includes a positioning block 91 and at least one side block 92. The rotating block 6 is rotatably mounted on the side block 92. The first connecting seat 8 includes a protrusion facing one end of the second connecting seat 9. The protrusion has a positioning groove that matches the positioning block 91. By setting the positioning block 91 and the protrusion, it is convenient to quickly connect the first connecting seat 8 and the second connecting seat 9. The wall thickness between the positioning block 91 and the side block 92 is greater than that of the protrusion, ensuring that there is enough space for the rotating block 6 and the locking block 7 to move when the first connecting seat 8 and the second connecting seat 9 are inserted, until the locking block 7 enters the locking groove 81 to fix the first connecting seat 8 and the second connecting seat 9. This facilitates the fixation of the handle part 1 and the massage part 2, the handle part 1 and the bent extension part 3, and the massage part 2 and the bent extension part 3 to each other.

[0038] like Figures 2-4 As shown, the elastic element 11 is a torsion spring. The top of the side block 92 has a notch, and a rotating rod 5 is rotatably mounted inside the notch. A rotating block 6 is fixedly installed on the outer surface of the rotating rod 5. The torsion spring is sleeved around the rotating rod 5. One end of the torsion spring abuts against the rotating block 6, and the other end abuts against the side block 92.

[0039] Taking the elastic element 11 as a torsion spring as an example, it is convenient to install on the rotating rod 5. By setting a notch, the rotating rod 5 can be avoided from being set on the side wall of the rotating block 6, thereby reducing the volume occupied by the rotating block 6 and the rotating rod 5 to a certain extent, and reducing the weight of the rotating block 6, i.e. the fascia gun as a whole.

[0040] Specifically, when it is necessary to assemble the handle part 1 and the massage part 2, the handle part 1 and the bending extension part 3, and the massage part 2 and the bending extension part 3, by adjusting the rotation of the rotating block 6 (specifically by pressing the rotating block 6), the torsion spring deforms, causing the locking block 7 to move away from the positioning block 91, thereby facilitating the insertion and positioning of the protrusion of the first connecting seat 8 with the positioning block 91. During this process, the locking block 7 will not contact the first connecting seat 8. After the protrusion is inserted and positioned with the positioning block 91, the rotating block 6 is released. Under the action of the torsion spring's rebound force, the rotating block 6 is driven to rotate closer to the positioning block 91 until the locking block 7 enters the slot 81, thereby completing the locking and fixing between the first connecting seat 8 and the second connecting seat 9.

[0041] like Figure 3 and Figure 4 As shown, a blocking part 921 is provided in the notch, and a stop block 61 is provided on the side of the rotating block 6 facing away from the locking block 7. When the first connecting seat 8 and the second connecting seat 9 are not in contact, the blocking part 921 is in contact with the stop block 61.

[0042] By setting the blocking part 921 and the stop block 61, when the handle part 1 and the massage part 2, the handle part 1 and the bending extension part 3, and the massage part 2 and the bending extension part 3 are separated from each other, that is, when the protrusion is disengaged from the positioning block 91, the continuous action of the torsion spring rebound force is prevented from causing the rotating block 6 and the locking block 7 to rotate too much. The rotation angle of the torsion spring is limited within its elastic deformation range, preventing permanent deformation due to excessive stretching or compression, and ensuring the reliability of long-term use.

[0043] like Figure 1 and Figure 2 As shown, it also includes a pressing member 4. The outer surfaces of the handle part 1 and the bending extension part 3 are slidably provided with pressing members 4. When the locking block 7 is located in the locking groove 81, one end of the pressing member 4 protrudes from the outer surfaces of the handle part 1 and the bending extension part 3. When the pressing member 4 gradually slides into the handle part 1 or the bending extension part 3, the pressing member 4 drives the rotating block 6 to rotate, and the locking block 7 gradually moves away from the locking groove 81.

[0044] By setting up such a pressing element 4, it is convenient to adjust the position of the rotating block 6 so that it rotates and squeezes the elastic element 11, thereby quickly separating the card block 7 and the card slot 81.

[0045] like Figure 1 As shown, the massage unit 2 is equipped with a transmission mechanism, which specifically includes a motor and a cam reciprocating motion structure. This is the existing structure of the fascia gun movement. The specific working principle will not be elaborated here. The handle 1 is equipped with a power source, which provides power to the transmission mechanism. The transmission mechanism is connected to the massage head 10.

[0046] like Figure 2 As shown, when the card block 7 is located in the card slot 81, the included angle between the rotating block 6 and the first connecting seat 8 is 5°-10°. Small-angle rotation does not require a large rotation path, making the overall structure more compact. It limits the rotation angle of the torsion spring within its elastic deformation range, preventing permanent deformation due to excessive stretching or compression, ensuring long-term reliability. Small-angle repeated deformation causes less stress on the material.

[0047] The torsion spring is made of stainless steel. The fatigue resistance of the stainless steel torsion spring further extends its service life. The diameter is not less than 0.5mm. Stainless steel of this thickness has a high elastic modulus and can ensure sufficient strength. The torsion spring is not easy to loosen under repeated deformation, ensuring that the locking force of the locking block 7 is stable over a long period of time. The rotating block 6 and the locking block 7 are made of aluminum alloy or nylon reinforced with fiber. They have high specific strength and can withstand the mechanical stress of repeated locking action. They are not easy to deform or break after long-term use, and the weight is relatively light, which will not increase the overall weight of the fascia gun too much.

[0048] 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.
