Description

Technical Field

[0001] The utility model belongs to the technical field of rhythmic sofas, and specifically relates to a rhythmic sofa leg support. Background Art

[0002] As people's pace of life accelerates, they have less and less time to participate in physical exercise. Long-term lack of exercise will lead to decreased physical function, fragile and inelastic blood vessels, and prone to cardiovascular and cerebrovascular diseases. Studies have shown that whole-body vibration of appropriate frequency can increase the friction between blood flow and blood vessels. The vascular shear force generated by vibration can increase vascular elasticity, promote endothelial cells on the inner wall of blood vessels to secrete nitric oxide to soften blood vessels, and reduce the occurrence of cardiovascular and cerebrovascular diseases. At the same time, the appropriate amplitude can relax tense muscles and relieve fatigue. The rhythmic sofa generates regular vibrations when the user is resting, thereby controlling the vibration of the user's body.

[0003] The leg rests in most existing rhythmic sofas do not have a storage function, so the leg rests will occupy a certain space, which will cause a waste of space and affect the overall appearance.

[0027] Furthermore, the inner wall of the groove opened at the top of the movable plate 311 is larger than the outer wall of the first rotating shaft 313, and the inner wall of the rotating groove opened in the inner wall of the groove fits closely with the outer wall of the first rotating shaft 313, so that when the movable plate 311 rotates, there will be enough space for it to move without any obstruction or collision with the inner wall of the groove.

[0028] Furthermore, there are several adjustment holes 318, which are evenly and equidistantly distributed on the bottom end of the inner wall of the placement groove 317. The inner wall of the adjustment hole 318 fits well with the outer wall of the support limit rod 316, so that the inclination angle of the support plate 3112 can be adjusted to adapt to the placement angle of the user's legs and improve the comfort of the user. At the same time, the inner wall of the adjustment hole 318 fits well with the outer wall of the support limit rod 316 to ensure that no shaking occurs during the limiting process, thereby ensuring stability during use.

[0029] Furthermore, a plurality of insertion holes are provided on the outer wall of the inner extension rod of the telescopic sleeve 314, and the insertion holes fit closely with the outer wall of the positioning rod 3111, so that the telescopic sleeve 314 can be adjusted in length up and down and then positioned by the positioning rod 3111, thereby further adapting to the actual usage of the user and improving its applicability.

[0030] The mobile positioning mechanism 32 includes a cavity opened on the outer wall of the rhythm sofa 1, the inner wall of the cavity is opened with a second limiting slide groove 321, the inner wall of the second limiting slide groove 321 is slidably connected with a second limiting slider 322, the outer wall of the movable plate 311 is opened with a sliding hole, the inner wall of the sliding hole is fixedly connected with a spring 323, the end of the spring 323 away from the inner wall of the sliding hole is fixedly connected with an insertion block 324, the outer wall of the insertion block 324 is slidably connected to the inner wall of the sliding hole, the outer wall of the insertion block 324 is fixedly connected with a connecting rod 325, the end of the connecting rod 325 away from the insertion block 324 is fixedly connected with a lever 326, and the inner wall of the cavity opened on the outer wall of the rhythm sofa 1 is opened with a slot 327.

[0031] Furthermore, the inner wall of the second limiting slide groove 321 fits snugly with the outer wall of the second limiting slider 322, and there are two second limiting sliders 322 that are symmetrically distributed on the left and right sides of the movable plate 311, thereby ensuring the stability of the movable plate 311 during movement. At the same time, the second limiting sliders 322 on the left and right sides can synchronously support and move the two sides of the movable plate 311 to the left and right, further ensuring stability during movement.

[0032] Furthermore, there are two plug blocks 324, which are distributed on the left and right sides of the movable plate 311 in a left-right symmetrical structure, so that the left and right sides of the movable plate 311 can be supported and limited simultaneously, ensuring the stability of the movable plate 311 after limiting and preventing shaking.

[0033] The implementation principle of a rhythmic sofa leg support of the present embodiment is as follows: when the movable plate 311 needs to be stored, the support plate 3112 is first pushed forward to drive the first rotating shaft 313 to rotate clockwise, so as to drive the second rotating shaft 315 and the supporting limit rod 316 to move. When the supporting limit rod 316 moves, it can be separated from the engaging and limiting effect between the inner wall of the adjustment hole 318. When the supporting limit rod 316 is separated from the inner wall of the adjustment hole 318, the torsion spring 312 can rebound and drive the first rotating shaft 313 to rotate counterclockwise, so as to drive the telescopic sleeve 314 and the support plate 3112 to rotate counterclockwise, so that the support plate 3112 moves to the storage groove opened at the top of the movable plate 311, and then the movable plate 3112 can be pushed The movable plate 311 enters the cavity opened by the outer wall of the rhythmic sofa 1 to complete the storage function. When the height of the support plate 3112 needs to be adjusted, the positioning rod 3111 is first pushed to the right. When the positioning rod 3111 moves, it will drive the first limit slider 3110 to move on the inner wall of the first limit slide groove 319, so that the outer wall of the positioning rod 3111 can be separated from the inner wall of the circular hole opened by the outer wall of the telescopic sleeve 314, thereby releasing the movement limit of the telescopic sleeve 314, and then the support plate 3112 can be pulled upward or downward to drive the telescopic sleeve 314 to extend or shorten, thereby realizing the adjustment of the height of the support plate 3112. When it is adjusted to a suitable position, the positioning rod 3111 can be pushed to insert into the inner wall of the circular hole again to complete the positioning of the telescopic sleeve 314.

[0034] When the movable plate 311 is pulled outward to move, the second limiting sliding block 322 will be driven to move against the inner wall of the second limiting sliding groove 321, so as to maintain the stability of the movable plate 311 during the movement. At the same time, the plug block 324 will be driven to move during the movement of the movable plate 311. When the plug block 324 moves to the position of the slot 327 opened on the inner wall of the cavity, the spring 323 can rebound and reset to push the plug block 324 to be inserted and connected to the inner wall of the slot 327, so as to position the movable plate 311 and prevent the movable plate 311 from being displaced during use, resulting in instability during use. When the contact positioning relationship is required, the levers 326 on both sides can be pushed to the middle position to drive the connecting rod 325 to move. When the connecting rod 325 moves, it will drive the plug block 324 to move outward, thereby breaking away from the card-connected positioning relationship with the inner wall of the slot 327.
