Description

Technical Field

[0001] This utility model relates to the field of massage mechanism technology, and in particular to a massage mechanism with a rotating push-out massage mechanism. Background Technology

[0002] Nowadays, people face increasing life pressures and become more and more physically exhausted. As a result, they need to use some auxiliary tools to relieve fatigue. With the widespread application of mechanization and automation, various massagers that simulate manual massage have entered thousands of households, and massage devices have thus emerged.

[0003] Currently, most massage devices on the market typically use gears and racks to drive the massage head to move up or down. For example, the "massage head device" disclosed in CN203802771 U uses a geared motor to drive a rack, which in turn drives the massage head to move up and down. With the help of a lead screw that can move back and forth, this setup can achieve massage at any position and with any intensity, thereby promoting blood circulation, making the body feel comfortable, improving the massage effect, and meeting the needs of people of different heights and body types, greatly enhancing the use of the massage bed.

[0004] However, this massage head device has certain drawbacks in use. First, the massage head needs to be raised and lowered frequently during use, and the person's back is usually pressed against the massage head. Therefore, the gears and racks are subjected to excessive pressure, resulting in greater wear on the gears and racks and a relatively short service life. Second, the arc-shaped rack used in this device requires high precision in machining, which is difficult and has a high processing cost. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a massage core with a rotating ejection massage mechanism, so as to solve the problems of the existing massage head device using a gear and rack structure for lifting and lowering, which causes greater wear on the gears and racks, resulting in a relatively short service life, and the high difficulty and cost of processing the arc-shaped rack.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a massage core with a rotating ejector massage mechanism, comprising:

[0007] A turntable, wherein at least one arc-shaped guide groove is formed on the top surface of the turntable along the circumferential direction, and the distance between the groove surface of the arc-shaped guide groove and the bottom surface of the turntable gradually increases or decreases along the circumferential direction;

[0008] A movable plate, located above the turntable;

[0009] Guide limiting component, wherein the movable plate is movably sleeved on the guide limiting component;

[0010] Guide plate, at least one guide plate is provided on the bottom surface of the movable plate;

[0011] The movable plate has at least one massage head on its top surface;

[0012] When the turntable rotates, the guide plate moves along the arc-shaped guide groove, and the movable plate moves up and down along the guide limit member.

[0013] Preferably, it also includes a drive mechanism, which includes a motor, a worm gear, a worm wheel, and a rotating shaft. The worm gear is fixedly installed at the output end of the motor, and the worm gear meshes with the worm wheel. The worm wheel, a turntable, and a guide limiter are fixedly connected to the rotating shaft from top to bottom.

[0014] Preferably, it also includes a housing, which includes a first outer shell and a second outer shell that are detachably and fixedly connected. The motor, worm gear and worm wheel are located inside the housing. The rotating shaft is rotatably mounted on the first outer shell and passes through the second outer shell. The turntable is located above the second outer shell.

[0015] Preferably, the guide limiting member is detachably and fixedly connected to one end of the rotating shaft. The guide limiting member has a second limiting ring on its outer wall. A through hole is provided through the movable plate. A first limiting ring is provided on the lower part of the inner wall of the through hole. The inner wall of the first limiting ring fits against the outer wall of the guide limiting member. The size of the inner wall of the through hole is not less than the size of the outer wall of the second limiting ring. There is a gap between the second limiting ring and the first limiting ring.

[0016] Preferably, the height of the guide limiting member and the second limiting ring is lower than the height of the massage head.

[0017] Preferably, the contact surface between the guide plate and the groove surface of the arc-shaped guide groove is properly fitted to the groove surface of the arc-shaped guide groove.

[0018] Preferably, the top surface of the turntable is provided with at least one limiting block.

[0019] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0020] Through the action of the arc-shaped guide groove, guide limit component and guide plate, when the drive turntable rotates, the guide plate moves along the arc-shaped guide groove, and the movable plate and guide plate make vertical lifting and lowering movements. The massage core with this structure has a long service life and low production cost. Compared with the existing massage devices that use a gear and rack lifting structure for lifting and lowering, it not only avoids the problem of high processing difficulty and high cost of arc-shaped racks, but also avoids the situation where the gears and racks bear excessive pressure when the human body presses on the massage head, resulting in greater wear on the gears and racks and a short service life.

[0026] 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.

[0027] like Figures 1-4 As shown, this utility model provides a massage mechanism with a rotating ejection massage mechanism, including a turntable 2, a movable plate 3, a guide limiting member 5, a guide plate 31, and a massage head 4;

[0028] At least one arc-shaped guide groove 21 is provided on the top surface of the turntable 2 along the circumferential direction. The distance between the groove surface of the arc-shaped guide groove 21 and the bottom surface of the turntable 2 gradually increases or decreases along the circumferential direction.

[0029] The movable plate 3 is located above the turntable 2. The movable plate 3 is movably sleeved on the guide limiter 5. The bottom surface of the movable plate 3 is provided with at least one guide plate 31, and the top surface of the movable plate 3 is provided with at least one massage head 4.

[0030] When the turntable 2 rotates, the guide plate 31 moves along the arc-shaped guide groove 21, and the movable plate 3 moves up and down along the guide limit member 5.

[0031] When a massage is needed, the body rests against the massage head 4 and presses against it, so that the massage head 4 is in a relatively stable state and does not rotate arbitrarily in the horizontal direction. When the turntable 2 rotates, due to the action of the arc-shaped guide groove 21, the guide limit piece 5 and the guide plate 31, the guide plate 31 moves along the arc-shaped guide groove 21, and the movable plate 3 and the guide plate 31 make vertical up-and-down movements.

[0032] This type of massage mechanism has a long service life and low production cost. Compared with existing massage devices that use a gear and rack lifting structure for lifting, it not only avoids the problems of high processing difficulty and high cost of arc-shaped racks, but also avoids the situation where the gears and racks bear excessive pressure when the human body presses on the massage head 4, resulting in excessive wear on the gears and racks and a short service life.

[0033] It should be noted that this massage mechanism can not only be mounted on a walking track for back massage, but also for direct massage of the feet or other parts of the body.

[0034] like Figure 2 and Figure 3 As shown, it also includes a drive mechanism, which includes a motor 6, a worm 7, a worm wheel 8 and a rotating shaft 9. The output end of the motor 6 is fixedly mounted with the worm 7, and the worm 7 and the worm wheel 8 mesh. The rotating shaft 9 is fixedly connected from top to bottom with the worm wheel 8, the turntable 2 and the guide limiter 5.

[0035] The motor 6 here is a dual-axis motor. Both the turntable 2 and the movable plate 3 are equipped with two sets. The motor 6 drives the two worm gears 7 to rotate in opposite directions by switching forward and reverse at a time. Each worm gear 7 drives the worm wheel 8 to rotate in opposite directions. The worm wheel 8 drives the rotating shaft 9 to rotate in opposite directions. The rotating shaft 9 drives the turntable 2 to rotate in opposite directions, thereby ultimately realizing the reciprocating lifting and lowering adjustment of the massage head 4.

[0036] like Figure 1 and Figure 2 As shown, it also includes a housing 1, which includes a first outer shell 11 and a second outer shell 12 that are detachably and fixedly connected (here they can be fixed by screws). The motor 6, worm 7 and worm wheel 8 are located inside the housing 1. The rotating shaft 9 is rotatably mounted on the first outer shell 11 and passes through the second outer shell 12. The turntable 2 is located above the second outer shell 12.

[0037] By setting up housing 1, the motor 6, worm 7 and worm wheel 8 are enclosed in a relatively sealed environment, thereby preventing a large amount of dust and debris in the air from adhering to the motor 6, worm 7 and worm wheel 8 and affecting the precision transmission between them.

[0038] like Figure 3As shown, the guide limiting member 5 is detachably and fixedly connected to one end of the rotating shaft 9 (it can be fixed here by screws). The guide limiting member 5 has a second limiting ring 51 on the upper part of its outer wall. The movable plate 3 has a through hole 32. The lower part of the inner wall of the through hole 32 has a first limiting ring 33. The inner wall of the first limiting ring 33 fits against the outer wall of the guide limiting member 5. The size of the inner wall of the through hole 32 is not less than the size of the outer wall of the second limiting ring 51. There is a gap between the second limiting ring 51 and the first limiting ring 33 to ensure the normal lifting and lowering movement of the movable plate 3.

[0039] By setting a second limiting ring 51, the first limiting ring 33 can be blocked and limited during the upward movement of the movable plate 3, thereby preventing the movable plate 3 from detaching from the guide limiting member 5. The inner wall size of the through hole 32 is equal to the outer wall size of the second limiting ring 51, which further plays a guiding and limiting role for the movable plate 3.

[0040] By setting a detachable guide limiter 5, the movable plate 3 can be easily disassembled and assembled. When the massage head 4 or guide plate 31 is damaged, it is easy to disassemble and replace it. Simply remove the screws that fix the guide limiter 5 and the rotating shaft 9, and the guide limiter 5 can be removed. In this way, the second limit ring 51 will no longer block the first limit ring 33, and the movable plate 3 can be removed, which makes it easy to replace the massage head 4 or guide plate 31.

[0041] like Figure 3 As shown, the height of the guide limiter 5 and the second limit ring 51 is lower than the height of the massage head 4, ensuring that when the turntable 2 rotates and drives the movable plate 3 and the guide plate 31 to move up and down, the guide limiter 5 and the second limit ring 51 will never come into contact with the human body, thereby ensuring that the massage head 4 performs massage work.

[0042] like Figure 4 As shown, the contact surface of the guide plate 31 and the groove surface of the arc-shaped guide groove 21 are properly fitted to the groove surface of the arc-shaped guide groove 21. By setting it in this way, the contact area between the arc-shaped guide groove 21 and the guide plate 31 can be maximized, thereby effectively reducing the pressure under the same pressure and thus slowing down the pressure loss of the guide plate 31 on the top surface of the arc-shaped guide groove 21.

[0043] like Figure 4As shown, the top surface of the turntable 2 is provided with at least one limiting block 22. By setting the limiting block 22, the movement of the guide plate 31 can be limited, further preventing the guide plate 31 from moving from the lowest point to the highest point (top surface of the turntable 2) along the arc-shaped guide groove 21 when the turntable 2 rotates. After being located on the top surface of the turntable 2, it will not detach from the top surface of the turntable 2 and fall into the next arc-shaped guide groove 21. This prevents the guide plate 31 from suddenly falling from the highest point (top surface of the turntable 2) of one arc-shaped guide groove 21 to the lowest point of another arc-shaped guide groove 21, thereby effectively preventing the guide plate 31 from colliding and being damaged by the arc-shaped guide groove 21.

[0044] 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.
