Description

Technical Field

[0001] This utility model relates to a bracket installed on a massage chair, and more particularly to a double-layered, rotatable, height-adjustable bracket. Background Technology

[0002] Modern massage chair phone or tablet holders are mostly adjustable. They are primarily made of sturdy and durable plastic or aluminum alloy to ensure stable support. Installation methods are diverse, with clip-on structures being common, allowing for easy attachment to the massage chair's armrests or other parts without interfering with normal use. Some holders feature multi-angle rotation and extension functions, catering to different users' viewing needs during massages, allowing them to comfortably watch videos or browse information while enjoying a massage, enhancing the entertainment experience.

[0003] Current massage chairs with double-layer supports suffer from insufficient adjustability. Their height adjustment range is limited, making it difficult to accommodate different sizes of massage chair armrests and user postures. This can result in the chair being too high or too low during use, affecting viewing comfort. Angle adjustment is also inflexible, failing to precisely meet the optimal viewing angle requirements for tablets or phones, reducing usability and preventing users from consistently enjoying a good visual experience during a massage. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a double-layer stacked rotatable lifting and adjusting bracket that can provide more adjustment flexibility.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a double-layered, rotatable, height-adjustable bracket, comprising a first placement mechanism for placing a mobile phone or a massager remote control and a second placement mechanism for placing a tablet. The first placement mechanism is detachably mounted on the second placement mechanism, and the second placement mechanism is fixed to the side armrest of a massage chair. The first placement mechanism includes an extension rod and a rotating rod rotatably mounted on the extension rod. One end of the rotating rod is rotatably mounted with a first bracket. The second placement mechanism includes a fixed rod for fixing to the massage chair armrest and an adjustment component. One end of the adjustment component is rotatably mounted with a second bracket, and the adjustment component can drive the second bracket to move up and down along the fixed rod and rotate around the center point of the fixed rod. The extension rod is inserted inside the fixed rod, and a fastener is provided between the extension rod and the fixed rod to fix the extension rod by the length of the extension rod extending beyond the fixed rod.

[0006] The beneficial effects of this utility model are as follows: the extendable rod can move up and down along the fixed rod, flexibly adjusting the height of the first placement mechanism, making it convenient for users of different heights to place their mobile phones or remote controls at a comfortable operating height, thus improving ease of use; the rotating rod rotates at the top of the extendable rod, allowing the angle of items on the first support to be changed at will, enabling users to view mobile phone information or operate the remote control from different directions without significantly moving their bodies, enhancing the flexibility of use. For the second placement mechanism, the adjustment component can move up and down along the fixed rod and rotate around it, allowing users to precisely adjust the tablet's position and angle according to their posture and eye level, finding the optimal viewing angle and height whether watching videos or performing other operations, reducing neck and eye fatigue. Furthermore, the first and second supports can rotate in all directions (this type of rotation is existing technology and will not be elaborated upon here), further increasing the number of scenarios the above solution can adapt to. Overall, these rich adjustment methods allow the support to better adapt to various usage scenarios and user needs, providing users with a more convenient, comfortable, and personalized device placement experience for enjoying leisure time on a massage chair, greatly improving the practicality and functionality of the support.

[0007] Furthermore, the end of the extension rod facing the rotating rod is provided with a rotation positioning groove, and the bottom of the rotation positioning groove is provided with a support platform for supporting the rotating rod. The inner circumferential wall of the rotation positioning groove is provided with a plurality of positioning blocks spaced apart circumferentially. The outer circumferential surface of the rotating rod is provided with a positioning protrusion, and the distance between adjacent positioning blocks is consistent with the width of the positioning protrusion. The positioning protrusion and the plurality of positioning blocks are all made of elastic material.

[0008] The positioning stop within the rotating positioning groove and the positioning protrusion on the rotating rod work together, both made of elastic material. This provides appropriate damping feedback during rotation, allowing users to experience clear tactile feedback and stable resistance whether rotating forward or backward. This enables more precise control of the rotation angle, meeting diverse viewing needs and enhancing flexibility and convenience. Simultaneously, the support platform effectively prevents the rotating rod from accidentally falling, ensuring the safety of items placed on the first support and preventing damage from falling due to a loose or slipping rotating rod. This improves the reliability and stability of the support, providing users with a safer and more comfortable experience, further enhancing the practicality and quality of the entire double-layered, stackable, rotatable, and adjustable support.

[0009] Furthermore, the end of the fixed rod facing the extension rod is configured as an expansion section. The expansion section is elastic and its outer circumferential surface is provided with a plurality of deformation grooves that penetrate the inner and outer sides of the fixed rod. When the fastener rotates to move toward the extension rod, the inner circumferential wall of the fastener presses the expansion section against the outer circumferential wall of the extension rod to form a fixation.

[0010] The design of the expansion joint of the fixed rod greatly optimizes the performance of the bracket. The deformation groove on the outer circumference of the expansion joint provides space for its tightening. When the fastener rotates and the inner circumferential wall presses against the expansion joint, the expansion joint can tightly fit the extension rod, achieving stable and reliable fixation. This effectively prevents the extension rod from accidentally slipping, ensuring the stability of the first placement mechanism after height adjustment and improving the structural stability of the entire bracket. Simultaneously, the fastener and fixed rod can be adjusted via a threaded connection, making operation simple and convenient. Users can easily adjust the extension length of the extension rod according to their needs. Furthermore, an annular boss can be provided on the outer circumference of the fixed rod. This annular boss represents the limit of movement of the fastener when the expansion joint is loosened along the direction of the fixed rod, preventing fixation failure due to threaded connection detachment. This further enhances the reliability of the bracket, reduces safety hazards caused by component loosening, extends the service life of the bracket, and provides users with a safer, more efficient, and durable user experience, enabling it to better adapt to various usage scenarios and needs.

[0011] Furthermore, the adjustment assembly includes an adjustment rod, one end of which is a second bracket capable of omnidirectional rotation, and the other end is provided with a positioning hole. A positioning element is rotatably disposed in the positioning hole, and when the positioning element rotates in the positioning hole, it can abut against the outer peripheral wall of the fixed rod to prevent the adjustment rod from sliding along the direction of the fixed rod and from rotating around the fixed rod.

[0012] The second bracket at one end of the adjustment rod can rotate omnidirectionally, allowing the tablet placed on it to be easily adjusted to multiple angles to meet the user's visual needs in different sitting postures or usage scenarios, greatly improving viewing comfort and ease of operation. Meanwhile, the positioning element in the positioning hole at the other end rotates and abuts against the outer wall of the fixed rod, effectively preventing the adjustment rod from sliding or rotating along the fixed rod direction. This ensures the stability of the tablet after it is adjusted to the appropriate height and angle, preventing accidental slippage from affecting the user experience.

[0013] Furthermore, a sleeve is provided between the inner peripheral wall of the adjusting rod and the outer peripheral wall of the fixing rod, and a clearance fit is formed between the sleeve and the inner peripheral wall of the adjusting rod. When the positioning member rotates in the positioning hole, it can abut against the outer peripheral wall of the sleeve.

[0014] The sleeve design in this bracket offers several advantages. Firstly, the sleeve is located between the inner circumferential wall of the adjusting rod and the outer circumferential wall of the fixed rod, forming a clearance fit. When the positioning component rotates and abuts against the outer circumferential wall of the sleeve, it effectively protects the outer circumferential wall of the fixed rod, preventing wear caused by direct contact and friction with the positioning component. This extends the service life of the fixed rod and ensures the stability and durability of the overall bracket structure. Secondly, the sleeve can be detachably installed, allowing for convenient and quick replacement when wear occurs due to long-term use. This eliminates the need for complex repairs or component replacements of the entire bracket, reducing maintenance and time costs. This ensures the bracket maintains good performance throughout long-term use, further enhancing its practicality and economy. Attached Figure Description

[0017] Figure 3 This is an anatomical diagram of the adjustment component according to an embodiment of the present invention. Detailed Implementation

[0018] This utility model embodiment provides a double-layered, stacked, rotatable, lifting, and adjustable bracket, such as... Figure 1-3 As shown: It includes a first placement mechanism 1 for placing a mobile phone or a massager remote control and a second placement mechanism 2 for placing a tablet, and the second placement mechanism 2 is fixed to the side armrest of the massage chair (not shown in the figure).

[0019] The first placement mechanism 1 includes an extension rod 11 and a rotating rod 12 rotatably mounted on the extension rod 11. A first bracket 13 is rotatably mounted at one end of the rotating rod 12 perpendicular to the axial direction of the extension rod 11. A rotating positioning groove 111 is provided at one end of the extension rod 11 facing the rotating rod 12. A support platform 113 for supporting the rotating rod 12 is provided at the bottom of the rotating positioning groove 111. A plurality of positioning blocks 112 are circumferentially spaced on the inner circumferential wall of the rotating positioning groove 111. A positioning protrusion (not shown in the figure) is provided on the outer circumferential surface of the rotating rod 12, and the distance between adjacent positioning blocks 112 is consistent with the width of the positioning protrusion (not shown in the figure). The positioning protrusion (not shown in the figure) and the plurality of positioning blocks 112 are all made of elastic material.

[0020] An extension rod 11 is inserted inside a fixed rod 21, and a fastener 3 is provided between the extension rod 11 and the fixed rod 21 to fix the extension rod 11 by the length it extends beyond the fixed rod 21. The end of the fixed rod 21 facing the extension rod 11 is configured as an expansion section 211. The expansion section 211 is elastic in its entirety, and its outer circumferential surface is provided with a number of deformation grooves 212 that penetrate the inner and outer sides of the fixed rod 21. When the fastener 3 rotates to move toward the extension rod 11, the inner circumferential wall of the fastener 3 presses the expansion section 211 against the outer circumferential wall of the extension rod 11 to fix it.

[0021] The adjusting assembly 22 includes an adjusting rod 221. One end of the adjusting rod 221, perpendicular to the axial direction of the fixed rod 21, is a second bracket 23 capable of omnidirectional rotation. The other end is provided with a positioning hole 223. A sleeve 222 is provided between the inner peripheral wall of the adjusting rod 221 and the outer peripheral wall of the fixed rod 21, and a clearance fit is formed between the sleeve 222 and the inner peripheral wall of the adjusting rod 221. The outer peripheral surface of the positioning member 224 and the inner peripheral surface of the positioning hole 223 are provided with a thread. When the positioning member 224 rotates in the positioning hole 223, it can abut against the outer peripheral wall of the sleeve 222 to prevent the adjusting rod 221 from sliding and rotating along the direction of the fixed rod 21.

[0022] The adjustment method between the various components in this embodiment is as follows: the rotating rod 12 moves through the slot between adjacent positioning blocks 112 via the positioning protrusion (not shown in the figure) and is positioned there to form the rotation and positioning of the rotating rod 12.

[0023] After the extension rod 11 reaches the desired length, rotate the fastener 3 to press the expansion section 211 onto the extension rod 11 to fix the extension rod 11.

[0024] Rotate the positioning member 224 to release the clamping between it and the sleeve 222, thereby adjusting the position of the adjusting rod 221 on the fixed rod 21 and the angle of its orientation. Then, fix the position of the adjusting rod 221 by rotating the positioning member in the opposite direction to prevent it from sliding along the direction of the fixed rod 21 and rotating around the fixed rod 21.

[0025] In addition, both the first bracket 13 and the second bracket 23 can rotate in all directions to adapt to more usage scenarios.

[0026] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
