DETAILED DESCRIPTION

[0033] In order to make the technical means, creative 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 embodiments, other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0034] As shown in FIG. Figures 1-7 The utility model provides a multi -section type lifting massage machine core, including first rotating disc 2, at least one second rotating disc 3, first guide plate 33, movable plate 6, second guide plate 61, guide limiting piece 5 and massage head 4.

[0035] The first rotating disc 2 top surface is provided with at least one first arc-shaped guide slot 21 along the circumferential direction, the distance between the groove surface of first arc-shaped guide slot 21 to the first rotating disc 2 bottom surface gradually increases or decreases along the circumferential direction, the lowest point position of the groove surface of first arc-shaped guide slot 21 has first blocking part 22, and the highest point position has second blocking part 23.

[0036] Specifically, as shown in FIG. Figure 6 The first blocking part 22 is the sidewall of the lowest point position of the groove surface of first arc-shaped guide slot 21, and the second blocking part 23 is the first protruding block protruding from the first rotating disc 2 top surface, and the first blocking part 22 and the second blocking part 23 can limit the first guide plate 33 to slide only on the first arc-shaped guide slot 21 and not to be separated.

[0037] The top surface of each second rotating disc 3 is provided with at least one second arc-shaped guide slot 31 along the circumferential direction, and the distance between the slot surface of the second arc-shaped guide slot 31 and the bottom surface of the second rotating disc 3 gradually increases or decreases along the circumferential direction;

[0038] The bottom surface of the second rotating disc 3 is provided with at least one first guide plate 33, and the bottom surface of the first guide plate 33 of the bottom surface of the second rotating disc 3 is in contact with the slot surface of the first arc-shaped guide slot 21;

[0039] The movable plate 6 is located above the second rotating disc 3;

[0040] The bottom surface of the movable plate 6 is provided with at least one second guide plate 61, and the bottom surface of the second guide plate 61 is in contact with the slot surface of the second arc-shaped guide slot 31;

[0041] The movable plate 6 and the second rotating disc 3 are movably sleeved on the guide limiting member 5, and the guide limiting member 5 penetrates through the second rotating disc 3 and the movable plate 6;

[0042] The top surface of the movable plate 6 is provided with at least one massage head 4;

[0043] Herein, one second rotating disc 3 is taken as an example for description:

[0044] When the human body needs to be massaged, the human body is pressed against the massage head 4 to make the massage head 4 in a relatively stable state, and the massage head 4 will not be randomly rotated in the horizontal direction;

[0045] When the ascending movement of the massage head 4 needs to be adjusted, the first rotating disc 2 is adjusted to rotate forward, and due to the action of the first arc-shaped guide slot 21, the guide limiting member 5 and the first guide plate 33, the first guide plate 33 moves along the first arc-shaped guide slot 21 to make the first guide plate 33 move upward in the vertical direction until the first guide plate 33 is in abutment with the second blocking portion 23, so that the first rotating disc 2 drives the second rotating disc 3 to rotate forward, and with the forward rotation of the second rotating disc 3, due to the action of the second arc-shaped guide slot 31, the guide limiting member 5 and the second guide plate 61, the second guide plate 61 moves along the second arc-shaped guide slot 31 to make the second guide plate 61 move upward in the vertical direction, thereby driving the movable plate 6 to move upward, and finally realizing the ascending movement of the massage head 4;

[0046] Conversely, when the massage head 4 needs to be adjusted to descend, the first rotating disc 2 is adjusted to rotate reversely. Due to the action of the first arc-shaped guide groove 21, the guide limiting piece 5 and the first guide plate 33, the first guide plate 33 moves along the first arc-shaped guide groove 21, so that the first guide plate 33 moves downward in the vertical direction until the first guide plate 33 abuts against the first blocking part 22, thereby the first rotating disc 2 drives the second rotating disc 3 to rotate reversely. Due to the action of the second arc-shaped guide groove 31, the guide limiting piece 5 and the second guide plate 61, the second guide plate 61 moves along the second arc-shaped guide groove 31, so that the second guide plate 61 moves downward in the vertical direction, thereby driving the movable plate 6 to move downward, and finally the descending movement of the massage head 4 is realized. Through such repeated adjustment, the reciprocating lifting movement of the massage head 4 can be realized.

[0047] The massage core with the structure has a long service life and low production cost. Compared with the existing massage device which is lifted and lowered through a gear and a rack, the massage core avoids the problems of high machining difficulty and high cost of the arc-shaped rack, and avoids the situation that the human body is pressed on the massage head 4, the gear and the rack bear too large pressure, the gear and the rack are greatly worn, and the service life is short.

[0048] At the same time, through the multi-section lifting structure, the distance between the massage head 4 and the first rotating disc 2 when the massage head 4 is lowered to the lowest position can be reduced as much as possible under the condition that the lifting stroke amplitude of the massage head 4 meets the massage requirement, so that the whole massage core has a smaller volume.

[0049] It should be noted that the massage core can be mounted on a walking track and is suitable for back massage, and can also be directly used for foot or other part of the body massage.

[0050] As shown in Figure 3 and Figure 4 , the guide limiting piece 5 is provided with a second limiting ring 51 located between the movable plate 6 and the second rotating disc 3. The second rotating disc 3 is provided with a through hole 32, and the inner wall of the through hole 32 is provided with a first limiting ring 37. The inner wall of the first limiting ring 37 is attached to the outer wall of the guide limiting piece 5. The inner wall of the through hole 32 is not smaller than the outer wall of the second limiting ring 51. When the second rotating disc 3 is at the lowest point, there is a gap between the second limiting ring 51 and the first limiting ring 37, which ensures the normal lifting movement of the second rotating disc 3.

[0051] Through the second limiting ring 51, the first limiting ring 37 can be limited during the upward movement of the second rotating disc 3, so as to prevent the second rotating disc 3 from being separated from the guide limiting piece 5. The inner wall of the through hole 32 is equal to the outer wall of the second limiting ring 51, which further plays a guiding and limiting role for the second rotating disc 3.

[0052] As shown in Figure 4 and Figure 7 The second rotating disc 3 is provided with a limiting plate 34, the movable plate 6 is provided with a frame plate 11 on the bottom surface, and the inner wall of the frame plate 11 is provided with a third limiting ring 111. The outer wall of the limiting plate 34 is in contact with the inner wall of the frame plate 11.

[0053] The frame plate 11 is detachably fixed to the bottom surface of the movable plate 6 by screws. The third limiting ring 111 and the limiting plate 34 can prevent the movable plate 6 from being separated from the guide limiting piece 5 during the upward movement of the movable plate 6.

[0054] As shown in Figure 5 A bottom groove 62 is formed on the bottom surface of the movable plate 6, which is matched in size with the outer wall of the second limiting ring 51. Thus, the distance between the movable plate 6 (i.e. the massage head 4) and the first rotating disc 2 can be further reduced, and the massage core as a whole is more compact.

[0055] When the number of the second rotating discs 3 is not less than two (not shown in the figure), the lowest point of the groove surface of the second arc-shaped guide groove 31 is provided with a third blocking part 35, and the highest point is provided with a fourth blocking part 36.

[0056] As shown in Figure 7 The third blocking part 35 is the side wall of the lowest point of the groove surface of the second arc-shaped guide groove 31, and the fourth blocking part 36 is a second protrusion protruding from the top surface of the second rotating disc 3. The third blocking part 35 and the fourth blocking part 36 can limit the second guide plate 61 to slide on the second arc-shaped guide groove 31 only and not to be separated.

[0057] Here, two second rotating discs 3 are taken as an example for description. The two second rotating discs 3 are stacked one above the other. When the lower second rotating disc 3 is lifted to the highest point by the first rotating disc 2, it will be rotated under the action of the second blocking part 23, and thus the lower second rotating disc 3 will drive the upper second rotating disc 3 to move upwards. When the upper second rotating disc 3 is moved to the highest point, it will be rotated under the action of the fourth blocking part 36 of the lower second rotating disc 3. Due to the actions of the second arc-shaped guide groove 31, the guide limiting piece 5 and the second guide plate 61, the movable plate 6 and the massage head 4 will finally move upwards.

[0058] Conversely, when the lower second rotating disc 3 is lowered to the lowest point by the first rotating disc 2, it will be rotated again under the action of the first blocking part 22, and thus the lower second rotating disc 3 will drive the upper second rotating disc 3 to move downwards. When the upper second rotating disc 3 is moved to the lowest point, it will be rotated under the action of the third blocking part 35 of the lower second rotating disc 3. Due to the actions of the second arc-shaped guide groove 31, the guide limiting piece 5 and the second guide plate 61, the movable plate 6 and the massage head 4 will finally move downwards.

[0059] As shown in Figure 2 andFigure 4 As shown, the massage movement also includes a drive mechanism, the drive mechanism includes motor 10, worm 7, worm gear 8 and shaft 9, the output end of the motor 10 is fixedly installed at least one worm 7, each worm 7 is engaged with a worm gear 8, the shaft 9 is sequentially fixedly connected with the worm gear 8, the first rotating disc 2 and the guide limiting piece 5 from bottom to top;

[0060] The motor 10 here is provided as a double-shaft motor, the first rotating disc 2 and the movable plate 6 are both provided with two groups, the motor 10 drives the two worms 7 to switch the rotation direction through the timing forward and reverse switching, each worm 7 drives the worm gear 8 to switch the rotation direction, the worm gear 8 drives the shaft 9 to switch the rotation direction, the shaft 9 drives the first rotating disc 2 to switch the rotation direction, so as to finally realize the reciprocating lifting adjustment of the massage head 4.

[0061] As shown in Figure 1 and Figure 2 The massage movement also includes a housing 1, the housing 1 includes a first housing 101 and a second housing 102 which are detachably fixedly connected (here, the screw is used for fixing), the motor 10, the worm 7 and the worm gear 8 are located in the housing 1, the shaft 9 is rotatably arranged on the first housing 101 and penetrates through the second housing 102;

[0062] The housing 1 is arranged for wrapping the motor 10, the worm 7 and the worm gear 8 in a relatively closed environment, so as to prevent a large amount of dust and debris in the air from adhering to the motor 10, the worm 7 and the worm gear 8, thereby affecting the precise transmission therebetween.

[0063] As shown in Figure 4 The guide limiting piece 5 is detachably fixedly connected to one end of the shaft 9 (here, the guide limiting piece 5 is arranged to be sleeved on the outer periphery of the shaft 9, and the bottom end abuts against the first rotating disc 2, the screw penetrates through the top end of the shaft 9, and the screw nut of the screw is used for pressing the guide limiting piece 5 tightly, so that the first rotating disc 2 and the guide limiting piece 5 are fixed), the detachable guide limiting piece 5 can facilitate the disassembly and assembly of the movable plate 6 and the second rotating disc 3, so that when the massage head 4 or the first guide plate 33 or the second guide plate 61 is damaged, the replacement can be facilitated;

[0064] The height position of the guide limiting piece 5 is lower than the height position of the massage head 4, so that the guide limiting piece 5 and the second limiting ring 51 do not contact the human body during the rotation of the first rotating disc 2 and the lifting movement of the movable plate 6, thereby ensuring the massage work of the massage head 4.

[0065] As shown in Figures 5-7 The contact surface of the first guide plate 33 and the groove surface of the first arc-shaped guide groove 21 is matched with the groove surface of the first arc-shaped guide groove 21, and the contact surface of the second guide plate 61 and the groove surface of the second arc-shaped guide groove 31 is matched with the groove surface of the second arc-shaped guide groove 31;

[0066] By so arranging, the contact area of the first arc-shaped guide groove 21 with the first guide plate 33 and the second guide plate 61 with the second arc-shaped guide groove 31 can be maximized, so that under the same pressure, the pressure can be effectively reduced, thereby slowing down the pressure loss of the first guide plate 33 on the top surface of the first arc-shaped guide groove 21 and the second guide plate 61 on the top surface of the second arc-shaped guide groove 31.

[0067] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
