[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In related technologies, the fixed base 100 of the beater frame is usually equipped with support pads at the bottom. The fixed base 100 and the support pads are relatively fixed. During the transportation of the beater frame to the placement area, the frame needs to be lifted manually, which is time-consuming and laborious. After being placed in the placement area, during the back-and-forth movement of the beater bracket 200, there is a possibility that the fixed base 100 will slide and displace. As a result, affected by the back-and-forth movement, the support pads will shift relative to the plane of the placement area. Therefore, the bottom of the fixed base 100 will deviate from the placement area forward or backward, resulting in poor stability and affecting the user experience.

[0035] The following is combined Figures 1-4 This invention describes a rhythmic motion frame and rhythmic furniture. The rhythmic furniture includes the aforementioned rhythmic motion frame and a supporting body. The supporting body can be moved rhythmically relative to the rhythmic motion by the reciprocating back-and-forth movement of the rhythmic motion frame. It is understood that, in embodiments of this invention, the aforementioned rhythmic furniture may be a rhythmic chair, a rhythmic bed, etc.

[0036] Understandably, referring to Figures 1-4 This utility model provides a rhythm frame, including a fixed base frame 100, a rhythm support 200, a drive mechanism 300, and an anti-displacement mechanism. The rhythm support 200 is movably mounted on the fixed base frame 100, and the drive mechanism 300 is mounted on the fixed base frame 100. The power output end of the drive mechanism 300 is connected to the rhythm support 200 to drive the rhythm support 200 to reciprocate back and forth relative to the fixed base frame 100. The anti-displacement mechanism includes a rotating wheel 400 and a limiting structure 500. The rotating wheel 400 is rotatably connected to the fixed base frame 100, and the limiting structure 500 is detachably connected to the fixed base frame 100. The limiting structure 500 is used to limit the up and down swing of the rotating wheel 400, and the limiting structure 500 can drive the rotating wheel 400 to reset.

[0037] When the limiting structure 500 is detached from the fixed base 100, the rotating wheel 400 can rotate circumferentially relative to the fixed base 100; when the limiting structure 500 is installed on the fixed base 100, the rotating wheel 400 can swing relative to the fixed base 100 following the movement of the rhythmic bracket 200, and under the drive of the limiting structure 500, the rotating wheel 400 swings in the opposite direction to reset.

[0038] The rhythmic motion frame provided by this utility model, through the action of the drive mechanism 300, allows the rhythmic support 200 to reciprocate on the fixed base frame 100. The fixed base frame 100 is equipped with an anti-displacement mechanism. During handling, the limiting structure 500 is not installed on the fixed base frame 100. Through the provided rotating wheel 400, the worker does not need to lift the rhythmic motion frame or push it to rotate the rotating wheel 400, thus achieving movement, saving time and effort. Furthermore, after the rhythmic motion frame is placed in the placement area, the limiting structure 500 is installed on the fixed base frame 100. When the rhythmic support 200 reciprocates back and forth relative to the fixed base frame 100, the rotating wheel 400 swings along with the movement of the rhythmic support 200. Driven by the limiting structure 500, the rotating wheel 400 swings in the opposite direction to return to its original position, which helps prevent unnecessary displacement of the fixed base frame 100 during the movement of the rhythmic motion frame, improving the stability of the fixed base frame 100 and providing a better user experience.

[0039] It should be noted that in this embodiment of the invention, when the aforementioned rhythmic frame is being transported, the limiting structure 500 is not installed on the fixed base 100, and the rotating wheel 400 rotates 360 degrees. When the limiting structure 500 is installed on the fixed base 100, there is resistance when the rotating wheel 400 rotates 360 degrees, causing the rotating wheel 400 to only swing up and down. Therefore, by swinging the rotating wheel 400 up and down, it can adapt to the forward and backward movement of the rhythmic support 200 of the rhythmic frame, so that there is relative movement between the rotating wheel 400 and the fixed base 100. Furthermore, the limiting structure 500 facilitates driving the rotating wheel 400 to swing back to its original state, thereby preventing the rotating wheel 400 from slipping.

[0040] It should be noted that, referring to Figure 1 In this embodiment of the invention, the fixed base 100 supports the rhythmic support 200. Of course, in some embodiments, the rhythmic support 200 can also be suspended above the fixed base 100. The anti-displacement mechanism consists of four sets, spaced apart at the bottom of the fixed base 100, i.e., arranged at intervals on the left, right, front, and back, to improve the stability of the fixed base 100. Of course, in some embodiments, the anti-displacement mechanism can be one set, two sets, etc., and is not limited here.

[0041] Understandably, referring to Figures 1-4In the embodiment of the utility model, the bottom of the fixed chassis 100 is equipped with a fixing base 110, the fixing base 110 is equipped with a fixing shaft 111, the rotating wheel 400 is equipped with an installation channel 410, the fixing shaft 111 is inserted into the installation channel 410 and both are rotationally matched, the cross section area of the installation channel 410 is larger than that of the fixing shaft 111; wherein the center line of the fixing shaft 111 is eccentrically arranged with the center line of the installation channel 410. Through the rotationally matched installation channel 410 of the rotating wheel 400 and the fixing shaft 111, the worker does not need to lift the rhythm machine frame, pushes the rhythm machine frame to make the rotating wheel 400 rotate, thereby realizing movement, and the structure is simple and convenient to assemble.

[0042] It should be noted that in the embodiment, the mounting seat is detachably mounted on the bottom of the fixed chassis 100 through the mounting bolt 120, of course, in some embodiments, the mounting seat can also be mounted on the bottom of the fixed chassis 100 by clamping, welding and the like, of course, the mounting seat can also be an integral structure with the fixed chassis 100, etc., which is not limited here. Correspondingly, it can be understood that the fixing shaft 111 is relatively fixed with the mounting seat, and the fixing shaft 111 and the mounting seat are an integral structure, or the fixing shaft 111 and the mounting seat can be connected and relatively fixed by bolts, clamping and the like.

[0043] It should also be noted that, referring to Figures 1-4 In the embodiment of the utility model, the rotating wheel 400 is a circular wheel body, which is simple in structure and convenient to manufacture, and the side surface of the arc-shaped path of the outer contour of the rotating wheel 400 is equipped with a plurality of anti-skid concave positions, so as to further limit the displacement of the rotating wheel 400 and improve the stability of the fixed chassis 100.

[0044] Specifically, referring to Figures 2-4 In the embodiment of the utility model, the cross section area of the installation channel 410 is larger than that of the fixing shaft 111; wherein the center line of the fixing shaft 111 is eccentrically arranged with the center line of the installation channel 410. By adopting the above structure, the rotating wheel 400 is eccentrically arranged with the fixing shaft 111 through the installation channel 410, therefore, when carrying the rhythm machine frame, the worker or user pushes the rhythm support 200 or the fixed chassis 100, which can make the rotating wheel 400 rotate relative to the fixing shaft 111, and the fixing shaft 111 always keeps in contact with the side wall below the installation channel 410, that is, the lowest position, which helps to keep the stable contact between the rotating wheel 400 and the fixing shaft 111, so that the rotation of the rotating wheel 400 relative to the fixing shaft 111 is more smooth, saving time and effort.

[0045] It should be noted that, referring to Figures 2-4In the embodiment, the center line of the mounting channel 410 coincides with the center line of the rotating wheel 400. Of course, in some embodiments, the fixing shaft 111 is adapted to the mounting channel 410 of the rotating wheel 400, and can be matched with the rotating wheel 400 after being mounted in the limiting structure 500, the limiting structure 500 can limit the rotating wheel 400 to only swing up and down, and can drive the rotating wheel 400 to reset.

[0046] It can be understood that, referring to Figures 1-3 In the embodiment of the utility model, the fixing shaft 111 is provided with a limiting plate 112, the limiting plate 112 is fixedly connected with the end of the fixing shaft 111 away from the fixing base 110, and the fixing base 110 and the limiting plate 112 have a spacing therebetween to form a limiting space for mounting and limiting the rotating wheel 400, thereby improving the relative stability between the rotating wheel 400 and the fixing shaft 111.

[0047] It should be noted that, referring to Figures 1-3 The limiting plate 112 always abuts against the lower part of the side wall of the rotating wheel 400 away from the mounting base. The limiting plate 112 is integrally formed with the fixing shaft 111, or the limiting plate 112 is fixedly connected with the fixing shaft 111 by means of bolt connection, clamping and welding, etc., which is not limited herein; the limiting plate 112 always abuts against the side wall of the rotating wheel 400 away from the mounting base,

[0048] It can be understood that, referring to Figures 1-4 In the embodiment, the limiting structure 500 includes a limiting piece 510 and an elastic piece 520, the limiting piece 510 is detachably inserted into the mounting channel 410, and the limiting piece 510 is fixedly matched with the rotating wheel 400, the elastic piece 520 is fixedly matched with the limiting piece 510, and the elastic piece 520 is detachably connected with the fixing chassis 100.

[0049] With the above structure, after the beater frame is moved to the placement area, the limiting member 510 is inserted into the installation channel 410. The limiting member 510 is fixedly linked with the rotating wheel 400, that is, the limiting member 510 rotates with the rotating wheel 400. Under the cooperation of the installation channel 410 and the limiting member 510, the rotating wheel 400 rotates eccentrically relative to the fixed shaft 111. When the rotating wheel 400 rotates eccentrically, there is rotational resistance. Therefore, after the limiting member 510 is inserted, the rotating wheel 400 cannot rotate smoothly in a 360-degree circumferential direction. The rotating wheel 400 rotates within a preset angle range, that is, the rotating wheel 400 swings up and down. Therefore, by swinging up and down, the rotating wheel 400 can adapt to the back and forth movement of the beater frame's rhythm support 200. There is relative movement between the rotating wheel 400 and the fixed base frame 100. And through the elastic member 520, it is beneficial to drive the rotating wheel 400 to swing back to the original state, thereby avoiding the phenomenon of the rotating wheel 400 slipping. When it needs to be moved away from the placement area, the elastic element 520 and the limiting element 510 are removed. The limiting element 510 is detached from the installation channel 410, and the rotating wheel 400 can smoothly rotate 360 ​​degrees around the fixed shaft 111. The design is reasonable, simplifies the limiting structure 500, and is easy to operate.
