Specific implementation

[0025] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all, based on the embodiments in the implementation, other embodiments obtained by the person skilled in the art without making creative labor all belong to the protection scope of the utility model.

[0026] As Figures 1-4 Indicated, the utility model provides a kind of fascia gun of battery convenient separate disassembly, including shell 1 and driving mechanism 3, shell 1 includes first shell 11 and second shell 12, driving mechanism 3 includes driving part 31 and movable cylinder 32 (for prior art), and movable cylinder 32 is detachably fixed with massage head (not drawn in the drawing, and specific dismounting principle is prior art), driving part 31 drives movable cylinder 32 and moves through shell 1, fascia gun further includes inner shell 2, battery 4 and fixing part 6;

[0027] The inner shell 2 is detachably connected with the first shell 11, the second shell 12 is detachably connected with the inner shell 2, the inner shell 2 is provided with a notch avoiding area 21 on one side of the top surface, when the first shell 11 and the second shell 12 are buckled, the inner shell 2 is located between the first shell 11 and the second shell 12, and the driving mechanism 3 is located between the first shell 11 and the inner shell 2;

[0028] The battery 4 is movably inserted into the first shell 11, one end of the battery 4 penetrates into the notch avoiding area 21 through the inner shell 2, at this time, the notch avoiding area 21 of the inner shell 2 is provided with a through slot 24 matched with the size of the battery 4;

[0029] The fixing member 6 is used for limiting and fixing the battery 4;

[0030] When the battery 4 needs to be replaced due to damage, first, the second shell 12 is disassembled, at this time, the muscle fascia gun is changed from the state of Figure 1 to the state of Figure 3 , at this time, only the top of the battery 4 is exposed to the air, then the fixing member 6 is disassembled, so that the battery 4 is no longer limited and fixed, that is, the battery 4 can be taken out from the through slot 24 of the notch avoiding area 21, at this time, the driving mechanism 3 is located between the first shell 11 and the inner shell 2, so that the contact between the dust in the air and the driving mechanism 3 is greatly reduced;

[0031] Therefore, when the battery 4 needs to be replaced, the driving mechanism 3 can be prevented from being completely exposed to the air, so that the dust in the air can be greatly reduced from falling on the driving mechanism 3, the heat dissipation of the motor of the driving mechanism 3 is prevented from being affected, the friction between the cam and the driven part (such as the push rod) is prevented from being increased, so that the transmission resistance is increased, the transmission efficiency is reduced, and at the same time, the small particles in the dust may play a role of abrasive in the cam transmission process, aggravating the wear of the cam profile and the surface of the driven part, and in the long run, such wear may cause the transmission accuracy to be reduced, and even cause a fault;

[0032] Further, a partition plate can be arranged on the first shell 11 or the inner shell 2, and the partition plate is arranged between the battery 4 and the driving mechanism 3, so that the dust in the air can be further prevented from entering the driving mechanism 3.

[0033] As shown in Figures 2-4 , the outer shell 1 is spherical, the first shell 11 and the second shell 12 are both hemispherical, the battery 4 is located on one side of the driving member 31, the first shell 11 and the inner shell 2 are fixed by screws, the outer wall of the inner shell 2 is provided with a plurality of clamping grooves 22, and the inner wall of the second shell 12 is provided with a plurality of plastic clamping blocks 122;

[0034] By arranging the spherical outer shell 1 and arranging the battery 4 on one side of the driving member 31, compared with the existing linear or L-shaped muscle fascia gun, the overall volume is reduced to a certain extent, and the muscle fascia gun is more compact and portable;

[0035] Here the second shell 12 and the inner shell 2 are fixed by clamping, specifically, the plastic clamping block 122 can be designed as a non-direct trapezoidal shape, so it has two inclined surfaces, which not only facilitates the plastic clamping block 122 to be quickly clamped into the clamping groove 22, but also facilitates the subsequent disassembly of the second shell 12, that is, pulling the second shell 12 away from the inner shell 2 to make the plastic clamping block 122 disengage from the clamping groove 22.

[0036] As shown in Figure 2 , Figure 4 and Figure 5 , the second shell 12 is provided with an opening 123 at the top, and the inner edge 124 is provided at the opening 123. The inner shell 2 is detachably fixedly connected to the cover plate 5. When the cover plate 5 is fixed to the inner shell 2, the cover plate 5 abuts against the inner edge 124.

[0037] Further, by setting the cover plate 5 and the inner shell 2, at this time the cover plate 5 abuts against the inner edge 124 and is fixed, thereby completing the more stable fixation of the second shell 12.

[0038] Specifically, as shown in Figure 3 and Figure 5 , the inner shell 2 is provided with at least one arc-shaped plate 8 opposite the opening 123 at the top. An arc-shaped groove 81 is formed on one side of the arc-shaped plate 8 along the arc length direction. The bottom of the cover plate 5 is provided with an arc-shaped strip 7 matched with the arc-shaped groove 81. At least one side of the arc-shaped strip 7 abutting against the arc-shaped groove 81 or the top of the inner shell 2 is provided with a groove 71. The inner wall of the arc-shaped groove 81 or the top of the inner shell 2 is provided with a plastic protrusion matched with the groove 71. By setting the plastic protrusion and the groove 71, the arc-shaped strip 7 is relatively stable when entering the arc-shaped groove 81 and is not easily slidable.

[0039] When it is necessary to fix the cover plate 5 to the inner shell 2, the cover plate 5 is placed in alignment with the opening 123 until the cover plate 5 abuts against the inner edge 124. At this time, the cover plate 5 is rotated clockwise, thereby driving the arc-shaped strip 7 to rotate clockwise, making the arc-shaped strip 7 slide along the arc-shaped groove 81, and finally making the plastic protrusion located in the groove 71, that is, completing the fixation of the cover plate 5 to the inner shell 2. At this time, the cover plate 5 further plays a role in compressing and fixing the second shell 12.

[0040] Conversely, when it is necessary to disassemble the cover plate 5 or the second shell 12, the cover plate 5 is forcibly rotated counterclockwise to ensure that the plastic protrusion can disengage from the groove 71, and then until the arc-shaped strip 7 completely disengages from the arc-shaped groove 81, so that the cover plate 5 can be taken out, and the second shell 12 can be further disassembled subsequently.

[0041] As shown in Figure 2 and Figure 3 , the fixing member 6 is a pressing plate, which is Z-shaped and has a first horizontal part, a second horizontal part and a vertical part. When the bottom surface of the first horizontal part abuts against the top surface of the battery 4, the second horizontal part is fixed to the bottom surface of the inner wall of the gap avoiding area 21 by screws.

[0042] When the battery 4 needs to be taken out, after the second shell 12 is disassembled, the pressing plate is disassembled, so that the pressing plate no longer fixes the battery 4, so that the battery 4 can be taken out from the through groove 24 alone, and when the battery 4 needs to be reinstalled, the new battery 4 can be placed in the through groove 24, and then the first horizontal part of the pressing plate is used to press the battery 4, and finally the pressing plate is fixed by using the screw, so that the separate disassembly and assembly of the battery 4 is completed.

[0043] As shown in Figure 3 and Figure 4 The inner shell 2 is provided with a plurality of guide grooves 23 on the outer wall, and the second shell 12 is provided with a plurality of guide blocks 121 on the inner wall.

[0044] By setting the guide blocks 121 and the guide grooves 23, the second shell 12 can be quickly assembled on the inner shell 2, and at this time the second shell 12 is sleeved on the periphery of the inner shell 2, and when the guide groove 23 moves into the guide block 121, the plastic clamping block 122 enters the clamping groove 22.

[0045] As shown in Figure 2 The driving member 31 comprises a motor, and the motor is horizontally located in the first shell 11, and the battery 4 is cuboid-shaped and is arranged perpendicular to the fitting surface of the first shell 11 and the second shell 12.

[0046] By such arrangement, compared with the horizontally placed battery 4, the volume of the spherical shell 1 can be maximally reduced, and the overall structure of the fascia gun is more compact.

[0047] As shown in Figure 1 The first shell 11 or the second shell 12 is provided with a carrying strap 9 on the outer wall, so that the fascia gun can be conveniently carried.

[0048] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
