DETAILED DESCRIPTION

[0022] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0023] To achieve the above purpose, the embodiments of the present invention adopt the following technical solutions: Figure 1 , Figure 4 A rotary telescopic synchronizer includes a bottom cover 10, and further includes a middle cylinder 20, a driving mechanism, a telescopic cylinder 40, a rotary guide assembly and a soft structure 50. The middle cylinder 20 is fixedly arranged on the end side of the bottom cover, the driving mechanism is arranged in the inner cavity of the middle cylinder, the telescopic cylinder 40 is arranged at the output end of the driving mechanism, and can be rotated and telescopically moved along the axial direction of the middle cylinder under the action of the rotary guide assembly. The soft structure 50 is arranged in the inner cavity of the telescopic cylinder. When in use, the rotary guide assembly is driven to move under the action of the driving mechanism, and the rotary guide assembly then drives the telescopic cylinder to move along the axial direction of the inner cavity of the middle cylinder in a spiral manner to drive the soft structure to perform a spiral telescopic action, thereby achieving a massage effect when the soft structure contacts the object to be contacted.

[0024] As a preferred technical solution of this embodiment, the driving mechanism includes a motor 310 and a turntable 320. The motor 310 is arranged on the inner side of the bottom cover 10, and the turntable 320 is fixedly arranged at the output end of the motor. In this way, the turntable rotates under the drive of the motor, and the turntable can drive the telescopic cylinder 40 to rotate when rotating. At the same time, under the action of the rotating guide component, the telescopic cylinder is driven to rotate and telescope along the axial direction of the inner cavity of the middle cylinder, thereby realizing the rotating and telescopic massage effect of the telescopic cylinder and the soft structure.

[0025] Furthermore, the driving mechanism also includes a motor cover 330, an electronic board 340, a battery 350 and a switch cover 360. The motor cover 330 is arranged inside the middle cylinder for fixing the motor. The electronic board 340 is electrically connected to the motor. The battery 350 is used to supply power to the motor. The switch cover 360 is electrically connected to the electronic board 340 for controlling the start and stop operation of the motor. The switch cover can extend outward to extend out of the bottom cover, thereby facilitating the user to operate the massager.

[0026] Furthermore, in order to improve the rotation stability of the turntable 320 , the output end of the motor 310 is connected to the turntable 320 via a bearing 370 .

[0027] Reference Figure 1 , Figure 2 , Figure 3 As a preferred technical solution of this embodiment, the rotary guide assembly includes a guide rod 710, a guide bracket 720, a spiral line 910 and a guide wheel group. The guide rod 710 is slidably connected to the turntable 320. The guide bracket 720 is specifically a cylindrical structure, and the guide bracket is arranged on the two opposite end sides of the middle cylinder 20 and the cup cover 60. The spiral line 910 is a closed loop line spirally arranged along the outer wall of the telescopic cylinder 40. The guide wheel group is arranged in the inner cavity of the guide bracket and cooperates with the spiral line. Furthermore, one end of the guide rod 710 is fixedly connected to the telescopic cylinder 40, and the other end is slidably connected to the turntable through the guide hole 321. When in use, the other end of the guide rod is slidably connected to the turntable. In this way, when the turntable rotates, the telescopic cylinder is driven to rotate through the guide rod. At the same time, under the cooperative limiting action of the spiral line and the guide wheel group, the telescopic cylinder can be driven to rotate and telescope, so as to drive the soft structure to perform a massage action.

[0028] Furthermore, the rotation and telescopic synchronizer also includes a cup cover 60 arranged at one end of the middle cylinder relative to the bottom cover 10. When the massager is in a non-massage state, the soft structure is contracted and accommodated in the inner cavity of the telescopic cylinder, and the cup cover is arranged at the end of the guide bracket, thereby covering the soft structure to protect the soft structure.

[0029] It should be noted that the bottom cover, middle tube, guide bracket and cup cover in the utility model can form a closed cylindrical structure. When in use, the cup cover can be opened, and the soft structure can be rotated and telescopically moved along the axis of the middle tube under the action of the driving mechanism to achieve the purpose of massage; when the massager is not in use, the soft structure is stored in the telescopic tube and can be sealed with the cup cover.

[0030] Furthermore, the guide wheel group includes two guide wheels 920 that are relatively rotatable and arranged on the inner wall of the guide bracket. A gap is provided between the two guide wheels for the spiral line to pass through. When the telescopic cylinder rotates with the turntable, the spiral line is limited by the guide wheels on both sides, so that it can move telescopically while rotating, and synchronously drive the guide rod to slide along the turntable, so as to obtain the rotation and telescopic action of the soft structure. The utility model uses the method of cooperating the spiral line with the guide wheel to achieve the massage effect of rotation and telescoping. Compared with the traditional method of cooperating the worm and the commutator, it has the advantages of simple structure, low energy loss and low noise.

[0031] Furthermore, a soft magnet seat 510 is provided at the bottom of the soft structure 50, a first magnet 520 is provided inside the soft magnet seat, and a second magnet 410 matching with the first magnet is provided at the bottom of the inner cavity of the telescopic cylinder 40. When in use, the soft structure can be stably installed inside the telescopic cylinder by utilizing the cooperation of the first magnet and the second magnet.

[0032] Furthermore, a cup ring 80 is provided at one end of the guide bracket 720 away from the middle tube 20, and a silicone ring 810 is provided between the cup ring and the guide bracket. The cup ring is set at the end of the guide bracket through the silicone ring. When in use, the soft structure passes through the cup ring. When the massager is in a working state, the soft structure can rotate and telescope outward from the position of the cup ring, and when in a non-working state, it is stored in a position close to the cup ring.

[0033] When the massager is working, the motor 310 drives the turntable 320 to rotate, and the turntable then drives the telescopic cylinder 40 to rotate through the guide rod 710, and the telescopic cylinder simultaneously drives the spiral line of its outer wall to rotate. Since the inner wall of the guide bracket 720 is provided with guide wheels 920 located on both sides of the spiral line, under the limiting guiding action of the guide wheels, the rotating telescopic cylinder 40 will rotate and telescope along the inner cavity of the middle cylinder 20, thereby driving the soft structure 50 to rotate and telescope, so as to achieve a massage effect; when the massager is in a non-working state, the soft structure 50 can be stored in the inner side of the guide bracket 720 under the action of the telescopic cylinder 40, and can be sealed by the cup cover 60.

[0034] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
