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 assembly structure. Background Technology

[0002] Traditional fascia guns are manufactured by die-casting the base, base connector, and mounting shell in one piece or by producing them separately and then assembling them. When the base is manufactured by die-casting, it is difficult to observe the quality of the base manufacturing because the base is inside the mounting shell. At the same time, it is difficult to perform a good oxidation treatment on the surface of the base, which also affects the quality of the product.

[0003] A Chinese utility model patent published on March 26, 2021, with publication number CN212789100U, describes a fascia gun. The fascia gun's fixing base connector is fixed to the outside of the mounting shell by screws passing sequentially through a first through hole formed in the fixing base connector, a second through hole formed in the mounting shell, and finally screwed into a threaded hole formed in the fixing base. This structure is simple to install, has high structural reliability, and can be disassembled and repaired if there is local damage, without the need for overall replacement, resulting in low maintenance costs. Producing the fixing base, mounting shell, and fixing base connector separately facilitates the oxidation treatment of the surfaces of the fixing base, mounting shell, and fixing base connector, thereby ensuring product quality.

[0004] However, when the fascia gun only uses screws to sequentially pass through the first through hole, the second through hole, and the threaded hole to fix the fixing body, the mounting shell, and the fixing base, the following problem exists: When only the fixing body is damaged and needs to be replaced, removing the screws will first cause the mounting shell and the fixing base to separate, and only then will the mounting shell and the fixing body be separated. If the mounting shell and the fixing base are not damaged, disassembling and reassembling them becomes a redundant action, thus increasing the time and trouble of replacing the fixing body. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a fascia gun with a novel assembly structure. This addresses the problems of existing fascia guns where, when the fixing seat, fixing seat connector, and mounting shell are integrally die-cast, it is difficult to observe the quality of the fixing seat manufacturing, and it is also difficult to perform good oxidation treatment on the surface of the fixing seat. Furthermore, in the case of separate fixing seats, fixing seat connectors, and mounting shells, when only the fixing seat connector is damaged and needs to be replaced after assembly, the fixing seat, fixing seat connector, and mounting shell must be completely disassembled, resulting in troublesome and time-consuming subsequent assembly.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fascia gun with a novel assembly structure, comprising a mounting shell, a connecting body, and a fixing seat. The mounting shell and the connecting body are both open at both ends and hollow inside. The fixing seat is detachably and fixedly connected to the inside of the mounting shell, and the connecting body is detachably and fixedly connected to the outer wall of the mounting shell. The connecting body and the inside of the mounting shell are in communication.

[0007] Preferably, the outer wall of the mounting housing is provided with at least one first mounting hole and at least one first threaded hole, the outer wall of the fixing seat is provided with at least one second threaded hole corresponding to the first mounting hole, and the hollow inner wall of the connecting body is provided with a ring plate, the ring plate is provided with at least one second mounting hole corresponding to the first threaded hole along its length direction.

[0008] Preferably, the outer wall of the mounting housing is provided with at least one positioning post, and the ring plate is provided with at least one positioning hole corresponding to the positioning post along its length direction.

[0009] Preferably, the positioning post has a third mounting hole extending through its length, and the third mounting hole is directly opposite and connected to the first mounting hole.

[0010] Preferably, it further includes a massage head, a telescopic component, a linkage component for driving the telescopic component to reciprocate, and a motor for driving the linkage component. One end of the telescopic component is connected to the massage head and the other end is connected to the linkage component. The motor is fixed on a mounting base.

[0011] Preferably, a guide cylinder is detachably fixed to the end of the connector away from the mounting housing, and the guide cylinder is sleeved around the telescopic component.

[0012] Preferably, the mounting housing has a top cover and a bottom cover that are detachably fixed at both ends, and a battery is provided between the bottom cover and the mounting base.

[0013] Preferably, the battery is provided with soft pads at both ends of the mounting base and the bottom cover, as well as on the outer wall.

[0014] Preferably, a circuit board is fixed on the bottom cover, the motor is electrically connected to the circuit board, the circuit board is electrically connected to the battery, and the soft pads at both ends of the battery abut against the bottom cover and the circuit board respectively.

[0016] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0017] When assembling the fascia gun, first fix the mounting shell and the base, then fix the connector to one side of the mounting shell. This not only avoids the situation where the quality of the base manufacturing cannot be observed when the mounting shell, connector and base are die-cast as a whole, but also facilitates good oxidation treatment of the base surface. At the same time, when only the connector is damaged and needs to be replaced, there is no need to disassemble the mounting shell and the base, making the replacement of the connector simpler and faster, saving assembly time.

Detailed Implementation

[0023] 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.

[0024] like Figures 1-4As shown, this utility model provides a fascia gun with a novel assembly structure, including a mounting shell 1, a connecting body 2, and a fixing seat 3. Both the mounting shell 1 and the connecting body 2 are open at both ends and hollow inside. The fixing seat 3 is detachably and fixedly connected to the inside of the mounting shell 1, and the connecting body 2 is detachably and fixedly connected to the outer wall of the mounting shell 1. The connecting body 2 and the inside of the mounting shell 1 are in communication.

[0025] When assembling the fascia gun, first fix the mounting shell 1 and the fixing base 3, and then fix the connector 2 to one side of the mounting shell 1. This not only avoids the situation where the quality of the fixing base 3 cannot be observed when the mounting shell 1, connector 2 and fixing base 3 are die-cast as a whole, but also facilitates good oxidation treatment of the surface of the fixing base 3. At the same time, when only the connector 2 is damaged and needs to be replaced, there is no need to disassemble the mounting shell 1 and the fixing base 3, so replacing the connector 2 is simpler and faster, saving assembly time.

[0026] like Figure 2 and Figure 4 As shown, the outer wall of the mounting housing 1 is provided with at least one first mounting hole 11 (four are taken as an example here) and at least one first threaded hole 12 (two are taken as an example here). The outer wall of the fixing base 3 is provided with at least one second threaded hole 31 corresponding to the first mounting hole 11. The hollow inner wall of the connecting body 2 is provided with an annular plate 21. The annular plate 21 is provided with at least one second mounting hole 211 corresponding to the first threaded hole 12 along its length direction. The second mounting hole 211 can be set as a threaded hole adapted to the second screw 14 or a movable through hole to accommodate the second screw 14.

[0027] When it is necessary to fix the housing 1 and the mounting base 3, place the mounting base 3 inside the housing 1, align the second threaded hole 31 with the first mounting hole 11, and use the first screw 13 to pass through the first mounting hole 11 and enter the second threaded hole 31, thereby completing the fixation between the housing 1 and the mounting base 3. Then, place the connector 2 on the side wall of the housing 1, align the first threaded hole 12 with the second mounting hole 211, and use the second screw 14 to pass through the second mounting hole 211 and enter the first threaded hole 12, thereby completing the fixation between the housing 1 and the connector 2.

[0028] like Figure 4 As shown, the outer wall of the mounting housing 1 is provided with at least one positioning post 111, and the ring plate 21 is provided with at least one positioning hole 212 that is directly opposite to the positioning post 111 along its length direction;

[0029] By setting the positioning post 111, after the fixing base 3 and the mounting shell 1 are fixed by the first screw 13, it is convenient to quickly position the connector 2 and initially position it on one side of the mounting shell 1. At this time, the first threaded hole 12 and the second mounting hole 211 are directly connected, which facilitates the precise insertion and fixing of the second screw 14. At the same time, it avoids the trouble of the traditional method of using screws to directly pass through the connector 2, the mounting shell 1 and the fixing base 3 and ensuring that the positions of the connector 2, the mounting shell 1 and the fixing base 3 are precisely aligned.

[0030] like Figure 4 As shown, the positioning post 111 has a third mounting hole 1111 extending through its length, and the third mounting hole 1111 is directly opposite and connected to the first mounting hole 11.

[0031] Both the third mounting hole 1111 and the first mounting hole 11 can be set as threaded holes that are compatible with the first screw 13. The positioning post 111 is located outside the first mounting hole 11. By setting the positioning post 111, it not only plays a role in quickly positioning and placing the connector 2, but also extends the length of the first screw 13. When it is necessary to fix the mounting housing 1 to the fixing base 3, one end of the first screw 13 is passed through the third mounting hole 1111 and the first mounting hole 11 and enters the second threaded hole 31. At this time, the nut abuts against the positioning post 111, thereby making the fixing between the mounting housing 1 and the fixing base 3 more stable.

[0032] like Figure 2 As shown, the fascia gun also includes a massage head 7, a telescopic component 6, a linkage component 5 for driving the telescopic component 6 to reciprocate, and a motor 4 for driving the linkage component 5. One end of the telescopic component 6 is connected to the massage head 7 and the other end is connected to the linkage component 5. The motor 4 is fixed on the fixed base 3.

[0033] The linkage assembly 5 here includes a crank wheel and a connecting rod. The crank wheel is fixed to the output shaft of the motor 4. One end of the connecting rod is rotatably connected to the crankshaft of the crank. The telescopic assembly 6 includes a telescopic rod and a sleeve. The other end of the connecting rod is rotatably connected to the sleeve. The sleeve is fitted and connected to one end of the telescopic rod. The massage head 7 is fixed to the other end of the telescopic rod by screws. Specifically, the inner wall of the telescopic rod facing the massage head 7 is provided with a first internal thread, and the outer wall of the massage head 7 facing the telescopic rod is provided with a first external thread that matches the first internal thread.

[0034] like Figure 2 As shown, a guide cylinder 9 is detachably fixed to one end of the connecting body 2 away from the mounting housing 1. The guide cylinder 9 is sleeved around the telescopic component 6. Specifically, the guide cylinder 9 is fixed to one end of the connecting body 2 by a threaded connection. A third external thread is provided on the outer surface of the guide cylinder 9 facing the end of the connecting body 2, and a third internal thread is provided on the inner wall of the connecting body 2 facing the end of the guide cylinder 9.

[0035] The guide cylinder 9 is used to support the telescopic component 6 (sleeve) and guide the movement of the sleeve, so as to further ensure the stability of the sleeve's reciprocating motion;

[0036] Furthermore, in order to reduce friction and wear between the guide cylinder 9 and the sleeve, a wear-resistant layer 22 is provided between the guide cylinder 9 and the sleeve, and the wear-resistant layer 22 is fixed to the inner wall of the guide cylinder 9.

[0037] like Figure 2 As shown, the top cover 10 and the bottom cover 15 are detachably fixed at the openings at both ends of the mounting housing 1, and a battery 8 is provided between the bottom cover 15 and the fixing base 3.

[0038] The top cover 10 and the bottom cover 15 are fixed to both ends of the mounting housing 1 by screws, which is stable and easy to disassemble and assemble. Specifically, the inner walls of both ends of the mounting housing 1 are provided with second internal threads, and the outer walls of the top cover 10 and the bottom cover 15 are respectively provided with second external threads that are adapted to the second internal threads.

[0039] like Figure 2 As shown, the battery 8 is provided with soft pads 16 at both ends of the mounting base 3 and the bottom cover 15, as well as on the outer wall.

[0040] The soft pad 16 here is made of EVA material, which reduces the noise generated by the collision between the battery 8 and the fixing base 3, the inner wall of the mounting shell 1 and the subsequent circuit board 23, and effectively reduces the possibility of mutual collision and squeezing damage.

[0041] like Figure 2 As shown, a circuit board 23 is fixed on the bottom cover 15. The motor 4 is electrically connected to the circuit board 23. The circuit board 23 is electrically connected to the battery 8. The soft pads 16 at both ends of the battery 8 abut against the bottom cover 15 and the circuit board 23 respectively.

[0042] The circuit board 23 is used to control the drive of the motor 4 and the operation of the subsequent heating element 17. By setting the circuit board 23 and the fixing base 3, after the bottom cover 15 is fixed to the bottom of the mounting shell 1, the circuit board 23 and the fixing base 3 clamp and limit the battery 8.

[0043] like Figure 2 As shown, the inner wall of the massage head 7 is provided with a heating element 17 (which can be set as an NTC thermistor, which is an existing structure). The heating element 17 is electrically connected to the first wire 18. The first wire 18 is detachably electrically connected to the conductive component 20 (the conductive component 20 can be set as a wire connection terminal, which is an existing structure, and the specific principle is not described in detail). The conductive component 20 is detachably electrically connected to the second wire 19. The second wire 19 is electrically connected to the circuit board 23.

[0044] By setting a detachable connection between the first wire 18, the second wire 19 and the conductive element 20, it is avoided to use a single wire to directly connect the heating element 17 to the circuit board 23, thus facilitating the normal disassembly and replacement of the massage head 7.

[0045] 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.
