Description

Technical Field

[0001] The utility model relates to the technical field of leg massage, in particular to a bidirectional screw rod switching mechanism for the up-and-down movement of a calf roller. Background Art

[0002] A general leg massage device includes a mounting frame and a massage mechanism disposed on the mounting frame, wherein the massage assembly includes a massage roller assembly rotatably disposed on the mounting frame, and the massage assembly also includes a motor assembly for driving the massage roller assembly to operate, and the massage roller assembly performs rolling massage on the calf.

[0003] However, the position of the massage roller group on this type of leg massage device cannot be adjusted relative to the mounting frame or the roller group can only move back and forth synchronously, so it can only provide fixed massage or mobile massage for the calf part, and it is impossible to combine fixed position massage with reciprocating synchronous massage. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a bidirectional screw switching mechanism for moving the calf roller up and down in view of the deficiencies of the above-mentioned prior art, which can switch the movement mode, so as to perform a full range of massage on the calf position, and can arbitrarily switch between fixed massage and mobile massage for different human bodies, thereby achieving a better massage effect.

[0005] To achieve the above-mentioned purpose, the following technical scheme is adopted: a bidirectional screw switching mechanism for moving a calf roller up and down, comprising a mounting frame and a driving motor, the driving motor driving a calf massage mechanism and a walking mechanism, the walking mechanism comprising a walking shaft, the calf massage mechanism being arranged on the walking shaft, the walking mechanism also comprising a bidirectional screw fixedly arranged on one side of the driving motor, the bidirectional screw being arranged vertically to the walking shaft, the walking shaft being provided with a helical gear, the bidirectional screw being provided with a driven gear meshing with the helical gear, a screw seat being fixedly arranged on the mounting frame, a paddle being provided in the screw seat cooperating with the bidirectional screw, the driving motor causing the calf massage mechanism to be positioned and rolled for massage when rotating forward; the driving motor transmitting the helical gear when reversing, the bidirectional screw rotating and cooperating with the paddle, thereby realizing the rolling massage of the calf massage mechanism along the up and down directions of the mounting frame.

[0006] By adopting the above technical solution, when the driving motor rotates forward, it drives the walking shaft to rotate. At this time, the walking shaft only drives the calf roller to roll and massage; when the driving motor rotates reversely, while driving the walking shaft to rotate, it can also drive the spiral gear to rotate. The spiral gear drives the driven gear to rotate, thereby driving the bidirectional lead screw to rotate. Through the paddle fixed in the screw seat on the mounting frame, the thread of the bidirectional lead screw moves up and down along the paddle, so that the driving motor, the walking shaft and the calf massage mechanism on the walking shaft can move up and down. The connection relationship between the walking shaft and the spiral gear is a one-way transmission, that is, when the walking shaft is controlled by the driving motor to rotate forward, the spiral gear The spiral gear does not rotate, and the calf massage mechanism rotates to achieve fixed massage. When the walking shaft is controlled to reverse by the driving motor, the walking shaft drives the spiral gear to rotate. At this time, the calf massage mechanism can move up and down through the cooperation of the two-way screw rod and the paddle. Therefore, by switching the forward and reverse rotation of the driving motor, the rolling massage of the calf roller and the mobile massage of the up and down movement of the walking shaft, as well as the corresponding fixed massage at the designated position can be controlled. At the same time, when the driving motor is reversed and the calf massage mechanism reaches the designated position, the driving motor can be rotated forward to only drive the calf massage mechanism to roll, thereby achieving fixed massage at the designated position.

[0007] A bidirectional screw switching mechanism for moving a calf roller up and down can be further configured as follows: a one-way bearing is provided inside the helical gear, and when the drive motor rotates forward, the one-way bearing causes the calf massage mechanism to roll and massage, and when the drive motor rotates reversely, the one-way bearing causes the helical gear to move, thereby realizing the calf massage mechanism to move up and down along the mounting frame.

[0008] By adopting the above technical solution, the one-way bearing slides with the inner ring of the helical gear when rotating forward. Therefore, the helical gear is not driven to rotate when the walking shaft rotates forward, and the one-way shaft is against the inner ring of the helical gear when rotating reversely, thereby driving the helical gear to rotate reversely. When the helical gear rotates reversely, it can mesh with the driven gear to transmit the transmission so that the thread of the bidirectional lead screw in the walking mechanism moves up and down along the paddle. Therefore, the bidirectional lead screw drives the drive motor and the walking shaft to move up and down. At this time, the calf massage mechanism also rolls to massage the calf, thereby forming a mobile massage that walks up and down. When the calf massage mechanism reaches the specified position by reversing the drive motor, the drive motor can be immediately rotated forward to achieve fixed massage of the specified position.

[0009] A bidirectional screw switching mechanism for moving a calf roller up and down can be further configured as follows: the mounting frame is provided with a walking slideway for the two ends of the walking shaft to extend into, the helical gear meshes and rotates with the driven gear so that the two ends of the walking shaft slide up and down along the walking slideway.

[0010] By adopting the above technical solution, both ends of the walking shaft extend into the walking slideway, so that they can slide up and down along the track defined by the walking slideway, and will not pop out due to the meshing transmission of the helical gear and the driven gear, causing unstable connection.

[0011] A bidirectional screw switching mechanism for moving a calf roller up and down can be further configured as follows: both ends of the bidirectional screw are sleeved with fixed seat sleeves, the fixed seat sleeves are fixed on a fixed seat, and the fixed seat is fixedly connected to one side of a driving motor.

[0012] By adopting the above technical solution, the two ends of the bidirectional screw rod can be rotated by fixing the seat sleeve, and the fixing seat is used to fix the bidirectional screw rod to one side of the driving motor.

[0013] A bidirectional screw switching mechanism for moving a calf roller up and down can be further configured as follows: a screw seat is fixedly connected to the mounting frame, a screw slot is provided on the screw seat for the bidirectional screw to extend into, a paddle slot is provided inside the screw slot, the paddle is inserted in the paddle slot and is threadedly connected to the bidirectional screw.

[0014] By adopting the above technical solution, the screw seat realizes the limitation of the up and down movement of the bidirectional screw through the screw groove, and the paddle is arranged in the paddle groove to make the up and down movement of the bidirectional screw more stable, so that the bidirectional screw is not prone to tooth derailment and slipping out when moving up and down. At the same time, an end cover can be arranged on the screw seat to facilitate the insertion of the paddle into the paddle groove.

[0015] A bidirectional screw switching mechanism for moving a calf roller up and down can be further configured as follows: the calf massage mechanism includes calf rollers arranged in pairs, and the calf rollers are fixed on the walking shafts at both ends of the driving motor.

[0016] By adopting the above technical solution, the calf roller can be fixed on the walking shafts at both ends of the driving motor, so as to realize rolling massage of the soles of both legs at both ends at the same time. The walking shaft can realize fixed massage of the corresponding designated position (that is, any upper or lower position of the calf) when the walking shaft rotates in the forward direction.
