Description

Technical Field

[0001] The present invention relates to a resetable one-way rotating foot massager. Background Art

[0002] At present, among the foot massagers with rotatable handle frames on the market, for example, a rotatable handle of a massager disclosed in a Chinese invention patent (CN215385850U), the handle frame adjusts the rotation angle of the handle through a ratchet mechanism in cooperation with an unlocking structure. The ratchet mechanism restricts the handle to rotate only in a single direction, and the unlocking mechanism can unlock the ratchet mechanism, so that the handle frame can rotate reversely. This adjustment method usually has a complex structure, many components, and often requires the user to free one hand to operate, which is relatively troublesome. In addition, all the foot massagers on the market at present can only massage the calf belly and the two sides at the back of the calf, and cannot effectively massage the front of the calf and the two sides at the front. Since there are many acupoints on the front side of the calf, such as Zusanli, Shangjuxu, Xiajuxu and other acupoints, regular massage of these acupoints is helpful for physical health.

[0025] An embodiment of the reset single-direction rotary foot massager of the present invention is as Figures 1-11 shown, and it includes a base 1, a handle 2 rotatably arranged on the base 1, and a cover plate 7 cooperatively connected with the base 1. A receiving hole 8 for placing the calf is formed at the connection between the base 1 and the cover plate 7. A massage mechanism is arranged in the receiving hole 8 of the base 1 and the cover plate 7. The handle 2 is of a U-shaped structure, and its two ends are respectively rotatably connected to both sides of the base 1. In addition, it further includes a first connecting member 3 connected to the base 1, a second connecting member 4 connected to the handle 2, and an elastic member 5 for driving the first connecting member 3 and the second connecting member 4 to axially approach along the rotation axis of the handle 2. When the handle 2 rotates relative to the base 1, a circumferential limit but axial movable connection fit is formed between the first connecting member 3 and the base 1. The second connecting member 4 is fixedly connected to the end of the handle 2, and the handle 2 can drive the second connecting member 4 to rotate relative to the first connecting member 3.

[0026] A one-way limit mechanism and a one-way limit release mechanism are arranged between the first connecting member 3 and the second connecting member 4.

[0027] This one-way limit mechanism can limit the relative rotation of the first connecting member 3 and the second connecting member 4 only in one circumferential direction when they axially approach, and make the one-way limit fit between them ineffective when they axially move away, that is, there is an axial clutch relationship between the first connecting member 3 and the second connecting member 4.

[0028] In this embodiment, the one-way limit mechanism includes a plurality of tooth blocks 31 circumferentially and spacedly arranged on the first connecting member 3, and a latch 41 arranged on the second connecting member 4. The relative rotation of the first connecting member 3 and the second connecting member 4 is limited to only one circumferential direction through the contact fit between the tooth blocks 31 and the latch 41.

[0029] One end of the tooth block 31 in the circumferential direction is provided with a first guiding inclined surface 311, and the other end is provided with a first limiting surface 312. One end of the clamping block 41 in the circumferential direction is provided with a second guiding inclined surface 411 that is guidingly matched with the first guiding inclined surface 311, and the other end is provided with a second limiting surface 412. When the second guiding inclined surface 411 of the clamping block 41 abuts against the first guiding inclined surface 311 of the tooth block 31, under the action of the elastic member 5, when a certain pressure is applied to drive the handle to rotate in a circumferential direction, the clamping block 41 is driven to cross over the tooth block 31 along the first guiding inclined surface 311 to its other end. At this time, the limiting cooperation between the first limiting surface 312 and the second limiting surface 412 can limit the reverse rotation of the handle. Due to the spaced arrangement of the plurality of tooth blocks 31, when the handle rotates to different positions, that is, when the clamping block 41 moves to the other end position of each tooth block 31, it can be limited, so that the handle 2 can be held at different rotation positions and is limited to rotate in only one direction.

[0030] The one-way limiting release mechanism is used to drive the first connecting member 3 and the second connecting member 4 to move axially away from each other and at the same time make the one-way limiting cooperation between the two ineffective when the handle 2 rotates to one of the circumferential end positions, and is used to make the first connecting member 3 and the second connecting member 4 move axially closer to each other and at the same time re-establish the one-way limiting cooperation between the two when the handle 2 rotates to the other circumferential end position.

[0031] In this embodiment, the one-way limiting release mechanism includes a guiding convex block 32 provided on the first connecting member 3. The abutting cooperation between the guiding convex block 32 and the clamping block 41 can drive the first connecting member 3 and the second connecting member 4 to move away from each other. The guiding convex block 32 has a third guiding inclined surface 321 that is guidingly matched with the second guiding inclined surface 411 of the clamping block 41. When the second guiding inclined surface 411 of the clamping block 41 abuts against the third guiding inclined surface 321 of the guiding convex block 32, it can drive the clamping block 41 to move along the third guiding inclined surface 321, so as to drive the first connecting member 3 and the second connecting member 4 to move away from each other, and at the same time can make the clamping block 41 away from the tooth block 31, and release the cooperation relationship between the two.

[0032] The first connecting member 3 includes a plug-in portion 30, the second connecting member 4 includes an inner hole 40 that cooperates with and sleeves the plug-in portion 30, and the one-way limit release mechanism further includes a guide groove provided on the outer peripheral surface of the plug-in portion 30 and a spring pin 42 provided at the inner hole 40 of the second connecting member 4. The guide groove extends circumferentially along the outer peripheral surface of the plug-in portion 30. The guide groove includes a first guide groove 331 and a second guide groove 332. The first guide groove 331 and the second guide groove 332 are axially communicated along the plug-in portion 30. The distance between the first guide groove 331 and the center of the plug-in portion 30 is greater than that of the second guide groove 332. A slope 333 is connected between the corresponding ends of the first guide groove 331 and the second guide groove 332. The spring pin 42 cooperates with the first guide groove 331 and the second guide groove 332 for guiding movement. The spring pin 42 includes a pin shaft and a spring that elastically drives the pin shaft to extend out.

[0033] When the first connecting member 3 and the second connecting member 4 are in a one-way limit cooperation state, the spring pin 42 is correspondingly located in the first guide groove 331 and can move along the first guide groove 331. When the first connecting member 3 and the second connecting member 4 move away from each other, the spring pin 42 extends from the first guide groove 331 into the second guide groove 332. Through the cooperation between the inner wall of the second guide groove 332 and the spring pin 42, the movement of the first connecting member 3 and the second connecting member 4 towards each other can be restricted, so that the two can be kept in a state of releasing the one-way limit cooperation, and the handle 2 can be driven to rotate in the reverse direction. When the spring pin 42 moves to the position of the slope 333, under the action of the elastic member 5, the spring pin 42 moves along the slope 333 and returns to the first guide groove 331, and then the one-way limit cooperation relationship between the first connecting member 3 and the second connecting member 4 can be re-established.

[0034] The plug-in portion 30 includes an inner hole 300. A connecting shaft 6 that cooperates with and is inserted and positioned in the inner hole 300 of the plug-in portion 30 is provided on the base 1. The elastic member 5 is a spring sleeved on the connecting shaft 5. Through the socketing cooperation between one end of the connecting shaft 6 and the inner hole 300, the axial displacement effect between the first connecting member 3 and the second connecting member 4 can be improved, and the force application direction of the spring can be ensured to be stable, thereby improving the reliability. The other end of the connecting shaft 6 is respectively provided with a stud and a limiting portion. The stud is locked and fixed to the base 1 through a nut, realizing the fixed connection between the connecting shaft 6 and the base 1. The limiting portion is used for abutting against the spring in cooperation.

[0035] As Figures 8-11As shown, the base 1 is provided with two grooves 11 for accommodating the calf, and the two grooves 11 are separated by a convex wall 12. There are two cover plates 7, and the two cover plates 7 are respectively provided corresponding to the two grooves 11. One side of the two cover plates 7 is respectively connected to the two sides of the base 1 by a pivot, and the other side of the two cover plates 7 is respectively matched with the convex wall 12 for positioning. The other side of the cover plate 7 and the convex wall 12 can be covered and positioned by snapping or magnetic attraction. In other embodiments, the cover plate 7 and the base 1 can also be connected by sliding or by disassembling the cover plate 7 as a whole.

[0036] Based on the connection and matching mode between the cover plate 7 and the base 1, the calf can be conveniently placed in or taken out of the receiving hole. The massage mechanism 71 provided on the cover plate 7 can be used to massage the front side of the calf. The massage mechanism 71 is a roller massage mechanism, which can also be an airbag massage mechanism or an electric stimulation massage mechanism. Specifically, an arc-shaped support plate 72 is provided on the inner side of the cover plate 7, and an arc-shaped recess 720 is provided on the inner side of the support plate 72, and the recess 720 is arranged in the direction of the groove 11. The massage mechanism 71 of the cover plate 7 is arranged on the inner wall of the recess 720, and an arc-shaped T-shaped groove is provided on the inner side of the cover plate 7, and an arc-shaped T-shaped guide rail 721 is provided on the outer side of the support plate 72. The T-shaped guide rail 721 is slidably connected with the T-shaped guide groove, and two groups of T-shaped guide rails 721 and T-shaped guide grooves are correspondingly provided. The cooperation between the T-shaped guide rail 721 and the T-shaped guide groove can constitute a sliding connection between the support plate 72 and the cover plate 7, so that the support plate 72 can slide along an arc-shaped motion trajectory relative to the cover plate 7, and a driving mechanism for driving the support plate 72 to move along an arc-shaped motion trajectory is provided on the cover plate 7. Specifically, an arc groove 722 is also provided on the outer side of the support plate 72, and an arc-shaped tooth row 723 is provided in the arc groove 722. The driving mechanism includes a motor provided on the cover plate 7, a gear 8 connected to the motor in a transmission manner, and the gear 8 is meshed with the tooth row 723. The gear 8 and the tooth row 723 are correspondingly provided at the middle position of the corresponding two groups of T-shaped slide rails 721, so that the force is more uniform and the structural reliability is improved. The tooth row 723 is provided in the arc groove 722, which is conducive to making the overall structure more compact and avoiding interference between the support plate 72 and the cover plate 7. When the motor is working, the gear 8 is driven to rotate, and the gear 8 drives the support plate 72 to move in an arc-shaped motion trajectory through the tooth row 723, so that the massage mechanism 71 on the support plate 72 can be driven to different positions on the front of the leg and on both sides of the front of the leg, so as to achieve more accurate massage. Through the periodic forward and reverse operation of the motor, it is also possible to achieve reciprocating and comprehensive massage of the front of the calf and both sides.
