Example 1:

as shown in fig. 2-4, the plug structure includes a connecting shaft 2 disposed at the plug end of the massage head 8, and a sleeve 1 disposed on the piston rod 7 and capable of being plugged and fixed with the connecting shaft 2, the connecting shaft 2 is provided with an elastic clamping member, the inner wall of the sleeve 1 is provided with a slot 11 capable of being clamped with the elastic clamping member, the electrical connection structure includes a power supply female head 231 disposed at the plug end of the connecting shaft 2, and a power supply male head 12 disposed at the bottom of the sleeve 1 and capable of being plugged with the power supply female head 231, the power supply female head 231 is provided with a wire connected with an electricity utilization module inside the massage head 8, and the power supply male head 12 is provided with a wire connected with a coil 72 on the piston rod 7.

The existing massage head 8 is mostly assembled with the piston rod 7 by adopting a soft rubber ferrule, the soft rubber is easy to deform and is not durable, after the massage head 8 and the piston rod 7 are used for a period of time, relative sliding occurs between the massage head 8 and the piston rod 7, and the electric connection structure is poor in contact and even breaks. This application utilizes the cooperation of elasticity joint spare and draw-in groove 11, has improved the stability of massage head 8 with the assembly of piston rod 7, combines grafting of public first 12 of power and the female head 231 of power to realize stable electricity and connects simultaneously to the orientation of first 8 of massage when pegging graft need not be in mind, consequently, the draw-in groove 11 of sleeve 1 inner wall can design for round annular groove, so that improve assembly efficiency.

For the elastic clamping piece, the following two schemes are adopted in the application:

the first method is as follows: a mounting cavity 21 is formed in the connecting shaft 2, through holes 22 and sliding grooves 23 are formed in the left side and the right side of the mounting cavity 21, a mounting hole 24 is formed in the bottom of the mounting cavity, and the elastic clamping piece is assembled in the mounting cavity 21; the elastic clamping piece comprises a dismounting button 211, a push plate 212, a left fixture block 213 and a right fixture block 214, a spring 215, a guide rod 216 and a guide groove 217 which are matched with each other are arranged between opposite surfaces of the left fixture block 213 and the right fixture block 214, a buckle 218 is arranged on the opposite surface, the buckle 218 of the left fixture block and the buckle 218 of the right fixture block penetrate through the left through hole 22 and the right through hole 22 of the installation cavity 21 respectively, a first inclined surface 201 and a second inclined surface 202 which are spliced into a cone are further arranged on the rear end surfaces of the left fixture block 213 and the right fixture block 214 respectively, a V-shaped surface 205 matched with the first inclined surface 201 and the second inclined surface 202 is arranged at the front end of the push plate 212, a third inclined surface 203 is arranged at the bottom of the push plate, the left side and the right side of the push plate 212 are connected with the sliding grooves 23 on the two sides of the installation cavity 21 in a sliding manner, the dismounting button 211 is slidably installed in the installation hole 24, a fourth inclined surface 204 matched with the third inclined surface 203 is arranged at the top of the push plate 212, and when the dismounting button 211 moves upwards, the dismounting button 211 moves, the dismounting button 212 moves towards the left fixture block 213 and the right fixture block 214.

The plug-in process of the scheme is as follows: when the massage head needs to be inserted, firstly, the detaching button 211 is pressed, the push plate 212 moves rightwards under the matching of the third inclined surface 203 and the fourth inclined surface 204, when the push plate 212 moves rightwards, the V-shaped surface 205 of the push plate 212 can drive the left clamping block 213 and the right clamping block 214 to fold towards the middle part, so that the clamping buckles 218 on the two sides retract into the connecting shaft 2, then the connecting shaft 2 can be smoothly inserted into the sleeve 1, finally, the detaching button 211 is loosened, the left clamping block 213 and the right clamping block 214 are propped open towards the two sides under the action of the spring 215, so that the clamping buckles 218 are clamped into the clamping grooves 11, and the inserting and fixing of the connecting shaft 2 and the sleeve 1 are realized; when the massage head needs to be disassembled, the massage head 8 can be easily taken out only by pressing the disassembling button 211 again to retract the buckle 218 into the connecting shaft 1.

The second method is as follows: as shown in fig. 5 and 6, the elastic clamping member is a spring and ball assembly, and includes a spring seat 221, a compression spring 222 and a ball 223, the spring seat 221 is a sleeve structure with an opening smaller than an inner diameter, the compression spring 222 and the ball 223 are sequentially disposed in the spring seat 221, and the ball 223 partially exposes the opening of the spring seat 221 under the elastic force of the compression spring 222; the installation cavity is two blind holes 25 arranged at two sides of the connecting shaft 2, the spring seat 221 is installed in the blind holes 25, and the opening end of the spring seat is flush with the surface of the connecting shaft 2. Through the clamping connection of the spring steel ball assembly and the clamping groove 11, compared with the traditional mode that the soft rubber ferrule is assembled with the piston rod, a certain clamping force can be provided, and the assembling stability of the massage head 8 and the piston rod 7 is improved.

Wherein, the preferred scheme is that the included angle between the axis of the blind hole 25 on the connecting shaft 2 and the axis of the connecting shaft 2 at the side close to the inserting end of the connecting shaft 2 is 50-70 degrees, and the included angle is preferably 60 degrees. During assembly, as the movable channel of the steel ball 223 is provided with the inclination angle, the pressure applied to the steel ball 223 by the massage head is the same as the moving direction of the steel ball 223, and the pressure angle is smaller at the moment, namely the required assembly force is smaller. In a detachable mode, due to the inclination angle of the movable channel of the steel ball 223, the pressure applied by the massage head to the steel ball 223 forms an included angle of 50-70 degrees with the moving direction of the massage head, and at the moment, the pressure angle is equal to the included angle. Because the pressure angle can reasonably be set to 0 degree during assembly, the required assembly and disassembly force proportion can be achieved by setting the pressure angle during disassembly, namely the required disassembly force is larger than the assembly force. Therefore, on one hand, the use experience of a user can be improved, and on the other hand, the occurrence of faults such as looseness and falling of the massage head can be effectively prevented.

The two elastic clamping pieces mainly improve the axial connection stability of the massage head 8 and the piston rod 7, and the radial direction needs the connecting shaft 2 to be in close contact with the sleeve 1 for limiting, so that the outer peripheral wall of the connecting shaft 2 is further provided with a mounting groove 26, and as shown in fig. 5, a rubber ring 27 or a silica gel ring is sleeved in the mounting groove 26. The rubber ring 27 or the silica gel ring can enable the connecting shaft 2 to be in close contact with the sleeve 1 after being inserted, so that the stability of the connecting shaft 2 and the sleeve 1 in the axial direction and the radial direction is guaranteed.

As for the electric connection structure, besides the insertion of the male power supply head and the female power supply head, another scheme can be adopted, as shown in fig. 7, that is, the electric connection structure includes an annular touch panel 241 arranged on the periphery of the end face of the insertion end of the connection shaft 2, a central touch panel 242 in the middle of the end face, and elastic contacts 15 arranged at the bottom of the sleeve 1 and capable of being respectively contacted with the annular touch panel 241 and the central touch panel 242, the annular touch panel 241 and the central touch panel 242 are both provided with wires to be connected with an electric module inside the massage head, and the two elastic contacts 15 are both provided with wires to be connected with a power supply on the massager. The annular touch panel 241 and the central touch panel 242 are respectively used as the positive and negative electrodes of the power utilization module, and the two elastic contacts 15 are respectively used as the positive and negative electrodes of the power output terminal, and similarly, the mode can also ensure that the massage head can be stably and electrically connected with the host when the massage head is inserted into the sleeve 1 in any direction. Meanwhile, the elastic contact 15 can avoid the faults of poor contact, open circuit and the like of the massage head in the vibration process.

The use process of the plug-in and electric connection structure is as follows: firstly, the elastic bulge structure on the connecting shaft 2 is aligned to the two grooves 13 on the sleeve 1, then the connecting shaft 2 is pushed into the sleeve 1, at the moment, the elastic bulge structure of the elastic conductive piece 28 can be properly compressed, and when the elastic bulge structure on the elastic conductive piece 28 reaches the position of the clamping groove 11, the elastic bulge structure can be clamped into the clamping groove 11 under the action of elasticity, so that the clamping and fixing of the connecting shaft 2 and the sleeve 1 are realized. Meanwhile, the conductive wire 281 in the connection shaft 2 is connected to the conductive strip 14 in the sleeve 1 by the elastic conductive member 28, so as to realize electrical connection, and due to the elastic force of the elastic conductive member 28, both ends of the conductive member are always kept in contact with the conductive wire 281 and the conductive strip 14, so as to ensure the stability of electrical connection.

According to different application and equipment structures, the connecting shaft 2 on the piston rod 7 and the sleeve 1 on the massage head 8 can be replaced with each other, and the corresponding conducting wire 281 and the conducting bar 14 are also connected with the corresponding electricity utilization module and the coil 72 instead.

In order to ensure the stability of the plug-in connection, the connection shaft 2 and the sleeve 1 need to be axially and radially limited. The cooperation joint of elastic bulge structure and draw-in groove 11 mainly guarantees both at ascending stability of axial, and radially then needs connecting axle 2 and sleeve 1 in close contact with spacing, consequently, the surface of connecting axle 2 or the internal surface of sleeve 1 have at least one to be plastics or rubber material, perhaps adopts to set up mounting groove 26 on connecting axle 2, and the mode of splicing rubber circle 27 in the mounting groove 26 makes connecting axle 2 and sleeve 1 form in close contact with after pegging graft.

The insertion end of the connecting shaft 2 refers to the end far away from the piston rod 7. After the blind hole 25 is obliquely arranged, when the assembly is carried out, the pressure exerted by the sleeve 1 on the steel ball 283 is close to the movement direction of the steel ball, and at the moment, the pressure angle is smaller, namely, the required assembly force is smaller; in a detachable mode, the pressure applied to the steel ball 283 by the clamping groove 11 forms about 60 degrees with the moving direction of the steel ball, and the pressure angle is larger at the moment, namely the required detaching force is larger. From this, arrange blind hole 25 through the slope, promoted user on the one hand and used experience, on the other hand can effectively prevent the not hard up emergence of trouble such as droing of sleeve 1.
