Description

Technical Field

[0001] The utility model belongs to the technical field of massagers, and specifically relates to a sitting type rhythm resonance mechanism. Background Technique

[0002] Rhythm can change the body's musculoskeletal nervous system through the physical action of gravity. When a person does vertical up-and-down rhythm, it will cause moderate blood flow shear force in the blood vessels. The blood flow shear force stimulates vascular endothelial cells to produce a beneficial hormone "nitric oxide" for the human body, and nitric oxide is a vasodilator and dredging agent of blood vessels, which can quickly dilate our blood vessels. Therefore, it can protect our heart and blood vessels. The vertical rhythm machine uses mechanical force to push the human body upwards, and when the mechanical force stops, the human body naturally falls under the action of gravity, thereby realizing up-and-down rhythm and safely stimulating every part of the whole body.

[0003] After retrieval, CN219398135U discloses a sitting type rhythm resonance mechanism. After being powered on, the motor rotates, the output shaft of the motor drives the small pulley to rotate, and the rotating shaft rotates through the transmission of the belt and the large pulley, so that the eccentric wheels on the rotating shaft rotate synchronously to make a yawing up-and-down reciprocating motion. After being transmitted through the swing fork, a up-and-down rhythm with the elastic sheet as the fulcrum is formed on the pedal, and the sole of the foot is massaged through the up-and-down rhythm. Its structure is simple, with few components and is convenient for maintenance.

[0004] The pedal in this mechanism is distributed in an inclined state. When the foot of the user is placed on it and moves up and down through rhythm, it will gradually move out of the upper part of the pedal. Therefore, the user needs to continuously adjust the foot position, which will greatly reduce the user experience and is not convenient for the user to use.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

A communicating sliding groove is formed in the outer wall of the connecting rotating plate. The outer wall of the shifting rod is slidably connected to the inner wall of the communicating sliding groove. A positioning seat is fixedly connected to the outer wall of the limiting cover on the side opposite to the fixed seat. A positioning hole is formed in the outer wall of the positioning seat. The outer wall of the positioning sliding rod is snap-fitted to the inner wall of the positioning hole.

[0010] As a preferred embodiment of the present invention, the auxiliary limiting mechanism includes an anti-slip plate fixedly connected to the top end of the pedal. A connecting block is fixedly connected to the top end inner wall of the limiting cover. A circular hole is formed at the bottom end of the connecting block. A second spring is fixedly connected to the top end inner wall of the circular hole. A sliding rod is fixedly connected to one end of the second spring away from the inner wall of the circular hole. The outer wall of the sliding rod is slidably connected to the inner wall of the circular hole. A pressing plate is fixedly connected to one end of the sliding rod away from the second spring.

[0011] As a preferred embodiment of the present invention, the number of the limiting covers is two, and the limiting covers are symmetrically distributed on the left and right sides of the top end of the pedal in a left-right symmetrical structure.

[0012] As a preferred embodiment of the present invention, a through groove is formed at the top end of the limiting cover, and chamfered arcs are provided at the edges of the through groove including the edge of the opening of the limiting cover.

[0013] As a preferred embodiment of the present invention, a bevel is provided at one end of the positioning sliding rod away from the connecting rotating plate, and the outer wall of the positioning sliding rod is fitted and adapted to the inner wall of the positioning hole formed in the outer wall of the positioning seat.

[0014] As a preferred embodiment of the present invention, the number of both the second spring and the sliding rod is two, and the second spring and the sliding rod are symmetrically distributed at the bottom end of the connecting block.

[0015] As a preferred embodiment of the present invention, the inner wall of the circular hole formed at the bottom end of the connecting block is fitted and adapted to the outer wall of the sliding rod, and the pressing plate is made of rubber material.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] In this utility model, when the lever is toggled and moved to the left, the positioning slide bar can be driven to move to the left and move along the inner wall of the connecting rotating plate. At the same time, during the movement, the first spring is squeezed and compressed. When the positioning slide bar moves to the left, the engagement and limiting effect between the positioning slide bar and the positioning hole formed on the outer wall of the positioning seat is released. Subsequently, the connecting rotating plate can be toggled to rotate clockwise through the rotational connection between the rotating shaft and the fixed seat. In this way, the connection between the connecting rotating plate, the positioning slide bar, and the limiting baffle can release the closed limit at the opening of the limiting cover. Then, the user can insert the foot into the interior of the limiting cover and place it normally on the pedal. After the placement is completed, the connecting rotating plate is directly pushed to rotate counterclockwise, thereby driving the positioning slide bar to rotate. At this time, the end of the positioning slide bar away from the connecting rotating plate will contact and be squeezed by the positioning seat, and then move to the left. At the same time, the first spring is squeezed again until the positioning slide bar moves to the inner wall of the positioning hole formed on the outer wall of the positioning seat. At this time, driven by the rebounding force of the first spring, the positioning slide bar is inserted into it, completing the closed limiting effect on the opening of the limiting cover. In this way, the foot can be limited by the limiting cover, preventing the foot from jolting and falling off the pedal during the rhythm movement. There is no need for the user to adjust the foot position manually, improving the user experience.

[0018] In this utility model, when the foot is inserted into the limiting cover, the instep will contact the pressing plate and exert an upward squeezing force on the pressing plate. At this time, the pressing plate will drive the slide bar to move upward. During the upward movement of the slide bar, the second spring will be squeezed and compressed until the foot is completely inserted into the limiting cover. Then, driven by the rebounding force of the second spring, the bottom end of the pressing plate is pushed back to fit and press on the instep, thereby providing an auxiliary limiting effect on the foot and improving the placement stability of the foot. At the same time, the anti-slip plate can further increase the friction between the pedal and the sole of the foot, further improving the placement stability of the foot.

Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0027] As Figures 1 to 4 shown, a seat-type rhythmic resonance mechanism includes a rhythmic base 1, support legs 2 fixedly connected to the bottom end of the rhythmic base 1, a limiting mechanism 31 is provided at the top end of the rhythmic base 1, and an auxiliary limiting mechanism 32 is provided above the limiting mechanism 31. The limiting mechanism 31 includes a pedal 311 fixedly connected to the top end of the rhythmic base 1. A limiting cover 312 is fixedly connected to the top end of the pedal 311. A fixed seat 313 is fixedly connected to the outer wall of the limiting cover 312. A through groove is opened on the outer wall of the fixed seat 313. A rotating groove is opened on the inner wall of the through groove. A rotating shaft 314 is rotatably connected to the inner wall of the rotating groove. A connecting rotating plate 315 is fixedly connected to the outer wall of the rotating shaft 314. A sliding hole is opened at one end of the connecting rotating plate 315 away from the rotating shaft 314. A first spring 316 is fixedly connected to the inner wall of the sliding hole. A positioning slide bar 317 is fixedly connected to one end of the first spring 316 away from the inner wall of the sliding hole. A shifting lever 318 is fixedly connected to the outer wall of the positioning slide bar 317. A limiting baffle 319 is fixedly connected to the outer wall of the positioning slide bar 317. A communicating chute is opened on the outer wall of the connecting rotating plate 315. The outer wall of the shifting lever 318 is slidably connected to the inner wall of the communicating chute. A positioning seat 3110 is fixedly connected to the outer wall of the limiting cover 312 on the side opposite to the fixed seat 313. A positioning hole is opened on the outer wall of the positioning seat 3110. The outer wall of the positioning slide bar 317 is snap-fitted to the inner wall of the positioning hole.

[0028] Furthermore, the number of the limiting covers 312 is two, and the limiting covers 312 are distributed in a left-right symmetric structure on the left and right sides of the top end of the pedal 311. In this way, the feet can be covered and limited, thereby ensuring the preliminary limiting effect of placing the feet on the top end of the pedal 311.

[0029] Furthermore, a through groove is opened at the top end of the limiting cover 312, and chamfered arcs are provided at the edges of the through groove, including the edges of the opening of the limiting cover 312. In this way, the ankle can be placed and moved, and at the same time, the chamfered arcs provided can protect the ankle, preventing it from being knocked against the edge during the up and down rhythm, causing injury.

[0030] Furthermore, an inclined surface is provided at one end of the positioning slide rod 317 away from the connecting rotating plate 315, and the outer wall of the positioning slide rod 317 fits closely with the inner wall of the positioning hole provided on the outer wall of the positioning seat 3110. Through the inclined surface setting, the positioning slide rod 317 can be directly engaged in the positioning hole when it is rotated counterclockwise, and there is no need to move the lever 318, which is convenient for limiting use.

[0031] The auxiliary limiting mechanism 32 includes an anti-skid plate 321 fixedly connected to the top of the pedal 311, a connecting block 322 is fixedly connected to the top of the inner wall of the limiting cover 312, a circular hole is opened at the bottom of the connecting block 322, a second spring 323 is fixedly connected to the top of the inner wall of the circular hole, the second spring 323 is fixedly connected to the end away from the inner wall of the circular hole with a sliding rod 324, the outer wall of the sliding rod 324 is slidably connected to the inner wall of the circular hole, and the sliding rod 324 is fixedly connected to the end away from the second spring 323 with a pressure plate 325.

[0032] Furthermore, there are two second springs 323 and two slide bars 324, which are symmetrically distributed at the bottom of the connecting block 322, so that the left and right sides of the pressure plate 325 can be supported and exerted simultaneously, thereby improving the uniformity of the force exerted by the pressure plate 325 on the foot.

[0033] Furthermore, the inner wall of the circular hole opened at the bottom end of the connecting block 322 fits snugly with the outer wall of the sliding rod 324, and the pressure plate 325 is made of rubber material, thereby ensuring the tightness between the sliding rod 324 and the inner wall of the circular hole during movement, thereby ensuring the stability of the downward force applied by the pressure plate 325. By setting it to rubber material, the friction limiting force between the instep and the pressure plate 325 can be increased, thereby further improving the limiting effect of the pressure plate 325 on the instep.

[0034] The implementation principle of a sitting-type rhythmic vibration mechanism in this embodiment is as follows: Before use, first move the lever 318 to the left. When the lever 318 moves, it can drive the positioning slide bar 317 to move to the left and move on the inner wall of the connecting rotating plate 315. At the same time, during the movement, the first spring 316 is compressed. When the positioning slide bar 317 moves to the left, the clamping and limiting effect between it and the positioning hole opened on the outer wall of the positioning seat 3110 is released. Then, the connecting rotating plate 315 can be rotated clockwise through the rotational connection between the rotating shaft 314 and the fixed seat 313. In this way, the connecting rotating plate 315, the positioning slide bar 317 and the limiting baffle 319 can release the closed limit at the opening of the limiting cover 312. Then, the user puts the foot into the inside of the limiting cover 312 and normally places it on the pedal 311. After placing, directly push the connecting rotating plate 315 to rotate counterclockwise, thereby driving the positioning slide bar 317 to rotate. At this time, the end of the positioning slide bar 317 away from the connecting rotating plate 315 will contact and be squeezed by the positioning seat 3110, and then move to the left, while squeezing the first spring 316 again until the positioning slide bar 317 moves to the inner wall of the positioning hole opened on the outer wall of the positioning seat 3110. At this time, driven by the rebounding force of the first spring 316, the positioning slide bar 317 is inserted into it, completing the closed limiting effect on the opening of the limiting cover 312, so as to limit the foot by covering, so as to prevent the foot from jolting and falling off above the pedal 311 during the rhythmic process, without the user having to adjust the foot position by himself, improving the use experience.

[0035] When the foot extends into the limiting cover 312, the instep will contact the pressing plate 325 and generate an upward pressing force on the pressing plate 325. At this time, the pressing plate 325 will drive the slide bar 324 to move upward. During the upward movement of the slide bar 324, the second spring 323 will be compressed. Until the foot completely extends into the limiting cover 312, the rebounding force of the second spring 323 will push the bottom end of the pressing plate 325 to fit and press on the instep, so as to assist in limiting the foot and improving the placement stability of the foot. At the same time, the anti-slip plate 321 can further increase the friction between the pedal 311 and the sole of the foot, further improving the placement stability of the foot.
