Description

Technical Field

[0001] The invention relates to the field of massage equipment, and in particular to a calf massage mechanism and a massage chair. Background Art

[0002] Patent publication CN111840019A discloses a device for massaging the legs. The device mainly comprises two rotatable kneading seats (numbered 31 in the document), and each kneading seat is provided with three rotatable rolling wheels. Since each kneading seat is rigidly mounted relative to the main body (numbered 1 in the document) (i.e., the kneading wheel cannot be extended or retracted relative to the main body), and the rolling wheels are also rigidly mounted relative to the kneading seats, the massage device cannot be matched and adapted to users with different leg thicknesses. For example, the rolling wheels may not be able to press on users with thin legs, and may cause greater squeezing discomfort to users with thick legs. Summary of the invention

[0003] In view of the above problems, the present invention proposes a calf massage mechanism, in which a kneading ring disk is slidably installed on a stepped rotating shaft by means of a limit screw and a limit stop ring, and a spring is simultaneously sleeved on the rotating shaft, thereby realizing an elastic sliding installation of the kneading ring disk relative to the rotating shaft. The kneading ring disk can rotate along the rotating shaft and also slide along the rotating shaft, thereby realizing an elastic sliding limit installation of the kneading ring disk. The elastic sliding limit installation of the kneading ring disk can well adapt to users with different leg thicknesses.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A calf massage mechanism comprises a chassis, a rotating shaft and a transmission shaft, wherein the rotating shaft is rotatably arranged on the chassis, the transmission shaft is rotatably arranged on the chassis, the rotating shaft is perpendicular to the transmission shaft, and further comprises a kneading ring disk and a spring, wherein the rotating shaft is a stepped rotating shaft, a sleeve clamp is arranged at one end of the kneading ring disk, and the sleeve clamp is located on one side of the center hole of the kneading ring disk, the sleeve clamp is slidably sleeved with the rotating shaft, the sleeve clamp is provided with the spring, one end of the spring abuts against the step on the side wall of the rotating shaft, and the other end of the spring abuts against one end of the sleeve clamp, a limiting screw is arranged at one end of the rotating shaft, and the limiting screw is located in the center hole of the kneading ring disk, a limiting stop ring is arranged in the hole wall of the center hole, and the limiting stop ring is located between the end of the rotating shaft and the end of the limiting screw.

[0006] The massage mechanism has a kneading ring disk which is slidably mounted on the rotating shaft through its sleeve clamp, and the kneading ring disk can slide relative to the rotating shaft (but at the same time, the rotation of the rotating shaft can drive the kneading ring disk to rotate together). At the same time, a limit screw is installed at one end of the rotating shaft, and the limit screw is located in the center hole of the kneading ring disk, so the limit screw can limit the sliding of the rotating shaft to ensure that the kneading ring disk will not completely slip off the rotating shaft. A limit stop ring is arranged in the hole wall of the center hole, and the limit stop ring is located between the end of the rotating shaft and the end of the limit screw. Therefore, when the kneading ring disk slides on the rotating shaft, the limit stop ring moves back and forth between the end of the rotating shaft and the end of the limit screw. Therefore, with the help of the limit stop ring and the limit screw, the sliding limit installation of the kneading ring disk relative to the rotating shaft is realized. At the same time, a spring is mounted on the rotating shaft, one end of the spring abuts against the step of the rotating shaft, and the other end of the spring abuts against the end of the sleeve clamp, so that the elastic sliding installation of the kneading ring disk is realized.

[0007] To sum up, this calf massage mechanism slides the kneading ring disc on the stepped rotating shaft with the help of a limit screw and a limit stop ring, and at the same time a spring is sleeved on the rotating shaft, so that the kneading ring disc is elastically installed relative to the rotating shaft. The kneading ring disc can rotate with the rotating shaft or slide along the rotating shaft, and after sliding, the spring can make the kneading ring disc slide back to the initial position. The kneading ring disc is used to massage the user, so the elastic sliding limit installation of the kneading ring disc can adapt well to users with different leg thicknesses.

[0008] Optionally, it also includes kneading protrusions, which are arranged on the kneading ring disk, and the sleeve clamp is located on both sides of the kneading ring disk because the kneading protrusions are respectively located. Each kneading ring disk is provided with multiple kneading protrusions, and the kneading protrusions on the same kneading ring disk are of different sizes.

[0009] The kneading protrusions of different sizes are arranged on the kneading ring disc in order to apply pressure of different strengths to the user's calf.

[0010] Optionally, a helical gear is provided on the rotating shaft, and a helical gear is provided on the transmission shaft, and the helical gear on the rotating shaft cooperates with the helical gear on the transmission shaft.

[0011] The rotating shaft and the transmission shaft are linked via helical gears.

[0012] Optionally, it also includes a transmission motor and a connecting gear set, the transmission motor is arranged on the chassis, and the shaft of the transmission motor and the transmission shaft are matched together through the connecting gear set.

[0013] The function of the transmission motor is to drive the transmission shaft to rotate by connecting the gear set.

[0014] Optionally, the chassis is provided with a support frame, the transmission shaft is rotatably mounted on the support frame, and a bearing is provided between the support frame and the transmission shaft.

[0015] The function of the support frame is to support the transmission shaft, and the function of the bearing is to ensure the stability of the transmission shaft when it rotates.

[0016] Optionally, it further includes a side block frame and a grid block frame, wherein the grid block frame is arranged on the chassis, the side block frames are arranged at both ends of the chassis, the grid block frame is located between the two side block frames, and the grid block frame and the side block frames are in a parallel and non-contact state.

[0017] Specifically, a kneading ring plate is arranged between the side blocking frame and the blocking frame, and the side blocking frame and the blocking frame are used to limit the calves of the user.

[0018] Optionally, the rotating shaft is a stepped cylindrical rotating shaft, the rotating shaft is provided with an outer fitting plane, the sleeve is provided with an inner fitting plane, and the outer fitting plane is in close contact with the inner fitting plane.

[0019] After the inner fitting plane and the outer fitting plane are pressed tightly together, the rotation of the rotating shaft can drive the kneading ring disc to rotate together.

[0020] Optionally, the chassis is a flat chassis, and the transmission shaft and the chassis are in a parallel and non-contact state.

[0021] Optionally, there are two rotating shafts, which are parallel and non-contacting, each rotating shaft is provided with a kneading ring disk, and the transmission shaft is located between the two rotating shafts.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0035] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, a calf massage mechanism includes a chassis 3, a rotating shaft 12 and a transmission shaft 8, the rotating shaft 12 is rotatably arranged on the chassis 3, the transmission shaft 8 is rotatably arranged on the chassis 3, the rotating shaft 12 is perpendicular to the transmission shaft 8, and also includes a kneading ring disk 4 and a spring (not shown in the drawings), the rotating shaft 12 is a step 1201 type rotating shaft 12, one end of the kneading ring disk 4 is provided with a sleeve clamp 11, and the sleeve clamp 11 is located on one side of the center hole 401 of the kneading ring disk 4, and the sleeve clamp 11 and the rotating shaft 12 are slidably sleeved. Assuming they are matched together, the sleeve collet is provided with a spring, one end of the spring abuts against the step 1201 on the side wall of the rotating shaft 12, and the other end of the spring abuts against one end of the sleeve collet 11 (that is, the spring is located between the sleeve collet 11 and the step 1201), one end of the rotating shaft 12 is provided with a limit screw 14, and the limit screw 14 is located in the center hole 401 of the kneading ring disk 4, and a limit stop ring 402 is provided in the hole wall of the center hole 401, and the limit stop ring 402 is located between the end of the rotating shaft 12 and the end of the limit screw 14.

[0036] In this massage mechanism, since the kneading ring disk 4 is slidably mounted on the rotating shaft 12 through its sleeve clamp 11, the kneading ring disk 4 can slide relative to the rotating shaft 12 (but at the same time, the rotation of the rotating shaft 12 can drive the kneading ring disk 4 to rotate together), and since a limit screw 14 is installed at one end of the rotating shaft 12, and the limit screw 14 is located in the center hole 401 of the kneading ring disk 4, the limit screw 14 can limit the sliding of the rotating shaft 12, ensuring that the kneading ring disk 4 will not completely slip off the rotating shaft 12, and a limit stop ring 402 is arranged in the hole wall of the center hole 401. The limit stop ring 402 is located between the end of the rotating shaft 12 and the end of the limit screw 14, so when the kneading ring disk 4 slides on the rotating shaft 12, the limit stop ring 402 moves back and forth between the end of the rotating shaft and the end of the limit screw 14. Therefore, with the help of the limit stop ring 402 and the limit screw 14, the sliding limit installation of the kneading ring disk 4 relative to the rotating shaft 12 is realized. At the same time, since a spring is sleeved on the rotating shaft 12, one end of the spring abuts against the step 1201 of the rotating shaft 12, and the other end of the spring abuts against the end of the sleeve 11, thereby realizing the elastic sliding installation of the kneading ring disk 4.

[0037] In summary, this calf massage mechanism slides the kneading ring disk 4 on the step 1201 type rotating shaft 12 by means of the limit screw 14 and the limit stop ring 402, and at the same time a spring is sleeved on the rotating shaft 12 to realize the sliding elastic installation of the kneading ring disk 4 relative to the rotating shaft 12. The kneading ring disk 4 can rotate with the rotating shaft 12 and can also slide along the rotating shaft 12, and after sliding, the spring can make the kneading ring disk 4 slide back to the initial position, and the kneading ring disk 4 is used to massage the user, so the elastic sliding limit installation of the kneading ring disk 4 can play a good adaptability to users with different leg thicknesses.

[0038] Combined with Figure 6As shown in the figure, the working principle of the mechanism is described in detail. First, during massage, the rotating shaft 12 is in a rotating state, and the rotation of the rotating shaft 12 drives the kneading ring disk 4 to rotate together. The end of the limit screw 14 is at the upper limit position 1501, and the end of the rotating shaft 12 is at the lower limit position 1502. When the kneading ring disk 4 is subjected to a downward squeezing force (the above-mentioned squeezing force can occur when the legs of the masseur are thicker), the kneading ring disk 4 moves downward. When the limit stop ring 402 contacts the upper limit position 1501, the kneading ring disk 4 stops moving downward, and under the elastic force of the spring, the kneading ring disk 4 moves upward again. When the limit stop ring 402 contacts the lower limit position 1502, the kneading ring disk 4 stops moving. Therefore, in this mechanism, the kneading ring disk 4 can float up and down, the kneading protrusions 5 are located at the top of the kneading ring disk 4, and the user's calves are located above the kneading protrusions 5. When the kneading ring disk 4 rotates, the kneading protrusions 5 perform a scraping massage on the user, and the up and down floating of the kneading ring disk 4 itself can continuously impact the user during the scraping process, thereby giving the user a more complete massage experience.

[0039] Specifically in this massage mechanism, the kneading ring disc, the sleeve clamp and the limit baffle are integrally formed.

[0040] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, it also includes kneading protrusions 5, which are arranged on the kneading ring disk 4, and the sleeve clamp 11 is arranged on both sides of the kneading ring disk 4 because the kneading protrusions 5 are respectively located. Each kneading ring disk is provided with multiple kneading protrusions 5, and the kneading protrusions 5 on the same kneading ring disk 4 are of different sizes.

[0041] The kneading protrusions 5 of different sizes are arranged on the kneading ring plate 4 to press the user's calf with different strengths. The kneading protrusions can be made of soft rubber material (including but not limited to rubber).

The transmission motor 7 is arranged on the chassis 3, and the shaft of the transmission motor 7 is matched with the transmission shaft 8 through the connecting gear set 6.

[0045] The function of the transmission motor 7 is to drive the transmission shaft 8 to rotate through the connecting gear set 6. The specific transmission motor and the connecting gear set are located in the blocking frame 2.

[0046] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, the chassis 3 is provided with a support frame 9, the transmission shaft 8 is rotatably mounted on the support frame 9, and a bearing 10 is provided between the support frame 9 and the transmission shaft 8.

[0047] The function of the support frame 9 is to support the transmission shaft 8, and the function of the bearing 10 is to ensure the stability of the transmission shaft 8 when it rotates.

[0048] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, it also includes a side block frame 1 and a grid block frame 2. The grid block frame 2 is arranged on the chassis 3. The side block frames 1 are arranged at both ends of the chassis 3. The grid block frame 2 is located between the two side block frames 1, and the grid block frame 2 and the side block frames 1 are in a parallel and non-contact state.

[0049] Specifically, a kneading ring plate 4 is arranged between the side blocking frame 1 and the blocking frame 2, and the side blocking frame 1 and the blocking frame 2 are used to limit the calves of the user.

[0050] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, the rotating shaft 12 is a cylindrical rotating shaft 12 with a step 1201 , the rotating shaft 12 is provided with an outer fitting plane 1202 , the sleeve 11 is provided with an inner fitting plane 1101 , and the outer fitting plane 1202 is in close contact with the inner fitting plane 1101 .

[0051] After the inner fitting plane 1101 and the outer fitting plane 1202 are pressed tightly together, the rotation of the rotating shaft 12 can drive the kneading ring disk 4 to rotate together.

[0052] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5As shown, the chassis 3 is a flat plate-shaped chassis 3, and the transmission shaft 8 is in a parallel and non-contact state with the chassis 3.
