Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 3, in order to solve the technical problems of complex structure and high noise of the telescopic structure of the existing massage device, an embodiment of the present disclosure provides a telescopic structure for driving a massage head to perform telescopic motion, including: a telescoping assembly.
In addition, referring to fig. 1, the telescopic assembly includes: the device comprises a power device 1, a gear mechanism 3, a speed change shaft 4, a transmission shaft 2, a hollow cylindrical joint 5, a limiting groove 6 and a column body 7.
On the other hand, the power unit 1 outputs a rotational torque through its output shaft.
It should be noted that the inventive concept of the disclosed embodiments includes converting the rotational torque into a translational force, thereby driving the corresponding component to move. The design of the execution part can be respectively carried out aiming at the rotating part and the transmission part by utilizing the conversion of force from rotation to translation, so that the structural design of the telescopic assembly is simplified.
In particular, the power unit 1 may be a rotary motor.
It should be noted that the rotary motor is small in size and light in weight, and therefore, is easy to install and design. In addition, the rotating motor occupies small space, the total volume of the telescopic structure can be reduced, and the use by a user is convenient.
In addition, the rotating motor has low noise when rotating, and the satisfaction degree of user experience can be improved.
However, the use of the rotary motor requires solving the problem that the rotary motor has a large output speed but a small torque, and because the massager mainly realizes the technical effect by pressing acupuncture points with a certain force, the output shaft of the rotary motor is meshed with a gear mechanism 3 through an output gear.
Briefly, the gear mechanism 3 is one or more speed change gears which keep the rotation torque of the output shaft stable on the basis of subtracting proper mechanical loss through mutual meshing relation, reduces the rotation speed of the output shaft, realizes rationalization of the expansion frequency of the expansion structure and promotes single expansion force.
Here, the speed change gear set is a set of gears of a plurality of coaxial sizes that are engaged with each other and that change the rotational speed between gears of different sizes by matching the linear velocity, and the gears of the coaxial sizes are fixedly installed by coaxially installing a large gear and a small gear to achieve the same rotational speed. Such a speed change gear set ensures substantial stabilization of the rotational torque while changing the rotational speed;
on the other hand, referring to fig. 1-3, the transmission shaft 2 has an axis for inserting and fixing the transmission shaft 4 and an outer wall with threads.
The axis of the transmission shaft 2 is inserted and fixed to the transmission shaft 4, and when the transmission shaft 4 outputs a rotational torque, the transmission shaft 4 can rotate with the rotation of the transmission shaft 4.
In addition, the screw thread is a power transmission part for converting rotation into translation, and after the adaptive execution part is connected with the screw thread, the execution part can move in parallel.
Specifically, referring to fig. 2, the thread 21 includes a plurality of diamond-shaped packing blocks b spaced apart on the outer wall of the drive shaft 2. Wherein, two adjacent rhombus package blocks b are separated by a fixed distance and are respectively positioned on two opposite side surfaces of the outer wall of the transmission shaft 2.
It should be noted that, two adjacent diamond-shaped packing blocks b are separated by a preset distance and are respectively located on two opposite side surfaces of the outer wall of the transmission shaft 2, so that a passage formed by a plurality of communicated groove bodies c is formed between the plurality of diamond-shaped packing blocks b, and the plurality of groove bodies c are distributed along the axial direction of the transmission shaft 2, and are similar to threads on screws.
Further, referring to fig. 3, both ends of the thread 21 are respectively provided with a limit protrusion d for limiting a moving range of the moving fork 24.
It should be noted that, the arrangement of the limiting protrusion d can limit the movement of the moving fork 24 which translates on the thread 21, so as to achieve the effect of limiting the movement range of the moving fork 24.
In another aspect, referring to fig. 1, a telescopic column, comprises: the device comprises a column body 7, a hollow cylindrical joint 5 positioned at one end of the column body 7 and a limiting groove 6 penetrating through one side of the hollow cylindrical joint 5;
wherein, the radial distance between the outer wall of the hollow cylindrical joint 5 and the axis of the telescopic column is smaller than the radial distance between the outer wall of the column body 7 and the axis of the telescopic column.
It should be noted that the radial distance from the outer wall of the hollow cylindrical joint 5 to the axis of the telescopic column is smaller than the radial distance from the outer wall of the column body 7 to the axis of the telescopic column.
It should be noted that the hollow part inside the telescopic column can be used for the transmission shaft 2 to pass through in the axial direction.
On the other hand, a fixed pressing block provided on the inner wall of the hollow cylindrical joint 5 may be used to fix the tip 241 of the moving fork 24. After the column body is sleeved with the outer wall of the hollow cylindrical joint 5, the hollow cylindrical joint extrusion fixing block, the hollow cylindrical joint 5 and the movable fork 24 are fixedly connected into a whole. Therefore, when the movable fork 24 moves along the thread 21, the fixed block and the hollow cylindrical joint 5 move integrally, so that the column body 7 moves therewith, thereby realizing the telescopic movement of the whole telescopic column along the thread 21.
On the other hand, referring to fig. 3, the top end 241 of the movable fork 24 passes through the limiting groove 2310 and is fixed with the extrusion fixing block, and the bottom end of the movable fork 24 is the fork body 240. Wherein the fork 240 is matingly engageable with the thread 21 and moves along the thread 21 when the drive shaft 2 is rotated.
It should be noted that the fork body 240 of the movable fork 24 can be engaged with the thread 21, so that the fork body 240 can move along the thread 21 when the transmission shaft 2 rotates.
Specifically, the top end 241 of the moving fork 24 is block-shaped, and the fork body 240 is arc-shaped.
It should be noted that the arc-shaped fork 240 is engaged with the thread 21, so that the resistance is small and the movement is fast.
It should be summarized that the moving fork 24 converts the rotation into the flat state by engaging the screw 21, not only achieving the effect of the expansion and contraction by a simple structure, but also the transmission of the force is performed in stages and smoothly transmitted, so that the mechanical noise generated is reduced.
Another object of the present invention is to provide a massage device, which comprises a massage head detachably connected to the above-mentioned retractable structure, so as to solve the technical problems of complicated structure and large noise of the existing massage device.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention,
any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
