Description

Technical Field

[0001] This utility model relates to the field of massage mechanism technology, specifically to an ultra-thin massage mechanism for a massage chair. Background Technology

[0002] Massage chairs use mechanical rolling and squeezing to massage. Manual massage can unblock meridians, promote blood circulation, and maintain the body's yin-yang balance. Therefore, after a massage, you can feel your muscles relax, your joints become more flexible, your spirits are refreshed, and your fatigue is eliminated. It plays an important role in ensuring good health. As the core component of a massage chair, the massage mechanism bears the same heavy responsibility as the human heart and is an indispensable part.

[0003] In a massage chair and its massage mechanism disclosed in patent CN202120687389.7, two mounting shafts located on the outside of the mechanism frame are provided. Compared with the single mounting shaft that runs through the mechanism frame in the existing massage mechanism, this can save the internal space occupied by the original mounting shaft, thereby reducing the overall volume of the massage mechanism and saving manufacturing costs. However, when the massage mechanism is in use, since the massage heads are basically the same diameter, when different users use the massage heads, the size of the massage heads will affect the subsequent massage use, causing users to feel uncomfortable when using the massage chair and making it inconvenient for subsequent massage use.

[0004] Therefore, we proposed that the ultra-thin massage mechanism of the massage chair can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an ultra-thin massage mechanism for a massage chair, in order to solve the problem mentioned in the background art that, in the current market, the massage heads of massage mechanisms are basically all the same diameter. When different users use the massage heads, the size of the massage heads will affect the subsequent massage use, causing discomfort and inconvenience to the users when using the massage chair.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultra-thin massage mechanism for a massage chair, comprising a mechanism body, a housing, a heat dissipation frame, a first massage head, and a second massage head. The mechanism body has a heat dissipation frame on its upper part, and a housing is located below the heat dissipation frame. The housing is located at the bottom of the mechanism body.

[0007] It also includes: both ends of the movement body are slotted and connected to turntables by bearings, and the two turntables are of the same size and the surfaces of the two turntables are circular.

[0008] Both ends of the left inner side of the turntable are equipped with drive shafts, and the two drive shafts have the same structure. A first massage head and a second massage head are threaded through the top of the two drive shafts respectively. A top cover is installed on the top of the first massage head and the second massage head through a slot, and the two top covers are connected to the first massage head and the second massage head by a piece of cloth.

[0009] Preferably, the turntable has an internal slotted bearing connected to a worm gear, with the rear end of the worm gear extending through to the outer side of the turntable. A throttle handle is connected to the outer side of the worm gear, and a worm wheel is meshed with the front side of the worm gear. A connecting rod is installed on the internal slotted bearing of the turntable, and a worm wheel is connected through the middle of the connecting rod. This allows the worm gear to rotate effectively, and the worm wheel then drives the connecting rod to rotate. This also facilitates the later use of the first and second connecting belts to rotate the two rotating rods.

[0010] Preferably, the upper and lower ends of the connecting rod are connected to the two rotating rods via a first connecting belt and a second connecting belt, respectively. The two rotating rods are mounted on the inner ends of the turntable with bearings. Both the first and second connecting belts are made of rubber. The first and second massage heads are symmetrically arranged about the vertical center line of the turntable, and the diameter of the first massage head is larger than that of the second massage head. This allows the two rotating rods to rotate and drive the two transmission shafts to push the top cover out, effectively shortening the massage width of the first and second massage heads and making it more convenient for the massage chair to use.

[0011] Preferably, both of the two rotating rods have slots on their upper interiors for providing buffer springs, and the two buffer springs have identical structures. Furthermore, both buffer springs are connected to a drive shaft, which can effectively buffer and depress the pressure of the first and second massage heads used for massage, thus preventing injury to the user from the first and second massage heads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The ultra-thin massage mechanism of this massage chair is equipped with a worm gear, a worm wheel, a connecting rod, a first connecting belt, and a second connecting belt. The worm gear is installed in a slot inside the turntable, and the worm wheel is meshed with the outside of the worm gear. The connecting rod, which is mounted on a bearing in a slot inside the turntable, passes through and is connected to the worm wheel. This allows the connecting rod to rotate, which in turn drives the first and second connecting belts to rotate the two rotating rods. This, in turn, drives the drive shafts above the two rotating rods to rotate. Because the two drive shafts are threaded through to the first and second massage heads respectively, the top covers of the first and second massage heads can be raised, thus reducing the width of the first and second massage heads and making them more convenient for different users.

[0014] The ultra-thin massage mechanism of this massage chair is equipped with a drive shaft, rotating rods, and buffer springs. The rotating rods are mounted on slotted bearings at the bottom of the two turntables, and the drive shafts are connected through slots above the two rotating rods. Buffer springs are installed in slots above the interior of the two rotating rods, and the drive shafts are connected above the two buffer springs. This effectively cushions and reduces shock for the first and second massage heads connected above the drive shafts, preventing injury to the user during massage and facilitating the subsequent use of the massage mechanism itself.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an ultra-thin massage mechanism for a massage chair, comprising a mechanism body 1, a housing 2, a heat dissipation frame 3, a turntable 4, a transmission shaft 5, a first massage head 6, a second massage head 7, a rotary handle 8, a worm gear 9, a worm wheel 10, a connecting rod 11, a first connecting belt 12, a second connecting belt 13, a rotating rod 14, a buffer spring 15, and a top cover 16;

[0023] The movement body 1 has a heat dissipation frame 3 on its top, and a housing 2 is located below the heat dissipation frame 3. The housing 2 is located at the bottom of the movement body 1.

[0024] It also includes: the left and right ends of the main body 1 are slotted and connected to turntables 4 by bearings, and the two turntables 4 are the same size and the surfaces of the two turntables 4 are round. The left inner ends of the turntables 4 are mounted with drive shafts 5 by bearings, and the two drive shafts 5 have the same structure. The top of the two drive shafts 5 are threaded through and connected to the first massage head 6 and the second massage head 7 respectively. The top of the first massage head 6 and the second massage head 7 are slotted and installed with top covers 16, and the two top covers 16 are connected to the first massage head 6 and the second massage head 7 by cloth.

[0025] A worm gear 9 is connected to the slotted bearing inside the turntable 4, and the rear end of the worm gear 9 extends through to the outer side of the turntable 4. A handle 8 is connected to the outer side of the worm gear 9, and a worm wheel 10 is meshed with the front side of the worm gear 9. A connecting rod 11 is installed on the slotted bearing inside the turntable 4, and the worm wheel 10 is connected through the middle of the connecting rod 11. The first massage head 6 and the second massage head 7 are symmetrically arranged about the vertical center line of the turntable 4, and the diameter of the first massage head 6 is larger than the diameter of the second massage head 7. The upper and lower ends of the connecting rod 11 are respectively connected by a first connecting belt 12 and a second connecting belt 13. The connecting belt 13 is connected to the two rotating rods 14, and the two rotating rods 14 are mounted on the inner ends of the turntable 4 by bearings. The first connecting belt 12 and the second connecting belt 13 are both made of rubber. The top cover 16 is threaded through the top of the drive shaft 5, and the top cover 16 is connected to the first massage head 6 by wrapping it with cloth. This can effectively move the top cover 16 to protrude, thereby shortening the usable width of the first massage head 6 and the second massage head 7, and making it easier for the main body 1 of the mechanism to be used in conjunction with the massage chair for massage.

[0026] like Figure 1-4 As shown, when the main body 1 is used with a massage chair, the width of the first massage head 6 and the second massage head 7 is adjusted by rotating the handle 8 to drive the worm gear 9 to rotate. Since the worm gear 9 and the worm wheel 10 are meshed, the connecting rod 11 connected inside the worm wheel 10 can be driven to rotate, thereby driving the first connecting belt 12 and the second connecting belt 13 to rotate the two rotating rods 14 respectively, which can effectively drive the transmission shaft 5 connected above the two rotating rods 14 to rotate.

[0027] Both rotating rods 14 have slots on their upper surfaces, and buffer springs 15 are installed inside. The two buffer springs 15 have identical structures, and both are connected to a drive shaft 5. Figure 1 , 5 As shown, when the first massage head 6 and the second massage head 7 are used for massage, the transmission shaft 5 connected to the bottom of the first massage head 6 and the second massage head 7 forms an elastic movement through two buffer springs 15, which can better facilitate the buffering and decompression of the first massage head 6 and the second massage head 7 in the later stage, and avoid the first massage head 6 and the second massage head 7 from causing injury to the user.

[0028] Working principle: When using the ultra-thin massage mechanism of this massage chair, firstly, rotating the handle 8 drives the worm gear 9 to rotate, which in turn drives the connecting rod 11 connected inside the worm wheel 10 to rotate. This, in turn, drives the first connecting belt 12 and the second connecting belt 13 to rotate the two rotating rods 14. This effectively drives the drive shaft 5 connected above the two rotating rods 14 to rotate. Because the top cover 16 and the first massage head 6 are connected by a cloth covering, the top cover 16 can be raised, thus shortening the usable width of the first massage head 6 and the second massage head 7. Subsequently, the drive shaft 5 connected to the bottom of the first massage head 6 and the second massage head 7 forms an elastic movement through two buffer springs 15, which can better facilitate the buffering and pressure reduction of the first massage head 6 and the second massage head 7 later, avoiding injury to the user caused by the first massage head 6 and the second massage head 7.
