Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] refer to Figures 1 to 5 A rotating mechanism, comprising a first component 1, a second component 2, and a rotating shaft 3;

[0035] The first component 1 is rotatably connected to the rotating shaft 3, and the first component 1 is provided with a first shaft hole 10 that mates with the rotating shaft 3;

[0036] The second component 2 is fixedly connected to one end of the rotating shaft 3, for example, by welding or flange, so that the second component 2 and the rotating shaft 3 are linked.

[0037] It also includes a drive assembly 5, which includes a gear 51, a rack 52 and a telescopic body 53;

[0038] Gear 51 is fixedly connected to the other end of rotating shaft 3, for example by welding or flange, so that gear 51 is linked with rotating shaft 3, thereby the second component 2 and gear 51 are linked.

[0039] One end of the telescopic body 53 is connected to the first component 1, and the other end of the telescopic body 53 is connected to the rack 52;

[0040] The telescopic body 53 can drive the rack 52 to reciprocate, and the rack 52 drives the gear 51 to rotate, thereby causing the first component 1 and the second component 2 to rotate relative to each other.

[0041] Thus, the relative rotation between the first component 1 and the second component 2 is achieved by driving the drive component 5. When the second component 2 is fixed, the first component 1 rotates under the drive of the drive component 5; when the first component 1 is fixed, the second component 2 rotates under the drive of the drive component 5.

[0042] The relative rotation angle between the first component 1 and the second component 2 is about 90 degrees, which can be understood as: the rotation angle range is approximately 90 degrees; of course, the rotation angle range can be set appropriately as needed.

[0043] A tooth 510 is provided in a quarter of the edge of the gear 51, that is, the tooth 510 is provided in a range of about 90 degrees. In this way, when the rack 52 engages with the tooth 510, it can drive the gear 51 to rotate about 90 degrees.

[0044] refer to Figure 4 and Figure 5 The mechanism also includes a support component 4, which is located between the first component 1 and the second component 2;

[0045] Support component 4 includes a limiting plate 41 and rollers 42;

[0046] The limiting plate 41 is rotatably connected to the rotating shaft 3, and the limiting plate 41 is provided with a second shaft hole that cooperates with the rotating shaft 3;

[0047] The limiting plate 41 is provided with multiple rollers 42, which are arranged around the rotating shaft 3; the limiting plate 41 is provided with a groove 411 that can accommodate the rollers 42, and the rollers 42 can roll in the groove 411. The diameter of the rollers 42 is slightly larger than the thickness of the limiting plate 41.

[0048] The support component 4 increases the contact area or the number of contact points between the first component 1 and the second component 2, thereby improving the stress strength and rotational stability. Furthermore, the roller 42 structure enables the first component 1 and the second component 2 to make contact through rolling friction, ensuring both stress strength and smooth rotation.

[0049] The limiting plate 41 is provided with two rings of rollers 42; that is, multiple rollers 42 are arranged in two or more rings in a circumferential array. The number of rings can be set appropriately as needed. Setting multiple rings of rollers 42 is beneficial to increasing the contact area or contact points, thereby improving the stability of the contact and the strength of the force.

[0050] refer to Figure 4 The telescopic body 53 is a cylinder or an electric actuator;

[0051] The drive component 5 is located on the side of the first component 1 away from the second component 2;

[0052] One end of the telescopic body 53 is connected to the first component 1, and the other end of the telescopic body 53 is connected to the rack 52. Both ends of the telescopic body 53 can be connected by hinge or fixed connection. Thus, the telescopic movement of the telescopic body 53 drives the rack 52 to reciprocate.

[0053] refer to Figure 4 The mechanism also includes a guide section 6, which includes a guide rail 61;

[0054] The guide groove 610 of the guide rail 61 is slidably connected to the rack 52; the rack 52 reciprocates along the guide groove 610, improving the accuracy of the rack 52's movement.

[0055] The guide section 6 also includes a stud 62 and a nut 63;

[0056] One end of the stud 62 can be connected to one side of the guide rail 61 by welding or plugging, and the other end of the stud 62 is connected to the nut 63; the nut 63 is connected to the first component 1;

[0057] Thus, the guide rail 61 is fixed to the first component 1 by a stud 62 and a nut 63 structure. Of course, the guide rail 61 can also be fixed to the first component 1 by welding or screws.

[0058] refer to Figure 4 The device also includes a protective section 7, which includes a first protective plate 71 and a second protective plate 72.

[0059] Both the first guard plate 71 and the second guard plate 72 are linked to the gear 51. For example, both the first guard plate 71 and the second guard plate 72 can be connected to the gear 51 by screws or studs 62, etc.

[0060] The first protective plate 71 and the second protective plate 72 are respectively disposed on the upper and lower surfaces of the gear 51, and both the first protective plate 71 and the second protective plate 72 extend horizontally out of the protruding teeth 510 of the gear 51. It can be understood that the area of ​​the first protective plate 71 and the second protective plate 72 is larger than that of the gear 51, so that they can cover the gear 51, and also make the first protective plate 71 and the second protective plate 72 form a limiting space that can accommodate the rack 52. Thus, the protective part 7 can not only protect the gear 51, but also form a limiting space or guiding space for the connection between the gear 51 and the rack 52, making the connection between the gear 51 and the rack 52 more stable and less likely to detach.

[0061] Assembly steps:

[0062] The second component 2 and the support assembly 4 can be assembled on the rotating shaft 3 first. The second component 2 is fixed to the rotating shaft 3 by welding. Then the first component 1 is assembled. Then the second guard plate 72, the gear 51 and the first guard plate 71 are sequentially fitted onto the rotating shaft 3. The three are fixed by screws or bolts. Then the gear 51 is fixed to the rotating shaft 3 by welding. Then the rack 52 and the telescopic body 53 are assembled.

[0063] The first component 1 can be designed as a frame structure or a plate structure, and the second component 2 can be designed as a plate structure or a frame structure.

[0064] This rotating mechanism can be applied to furniture such as shampoo beds, massage chairs, foot bath chairs, beauty beds, sofas, and seats. By setting the rotating mechanism between the bed or chair body and the base, the angle of the bed or chair body can be rotated and adjusted.

[0065] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
