[0034] Example 1

[0035] like Figure 1-7 As shown, a preferred embodiment of an adjustable lumbar relief device provided by the present invention includes a seat body 1, which is suitable for fixing the adjustable lumbar relief device or placing it on an object for use; a buffer component 2, which is connected to the seat body 1 and is elastic and suitable for supporting the user's waist; an adjustment component 3, which is movably connected to the seat body 1, and the movable stroke of the buffer component 2 is adjusted by the adjustment component 3, thereby changing the height of the buffer component 2 to meet the personalized needs of different users and achieve the purpose of effectively relaxing and soothing the waist.

[0036] Specifically, the buffer component 2 can adopt, for example, the elastic panel in this embodiment, and the two ends of the elastic panel respectively abut the base 1 and the adjustment component 3, and the adjustment component 3 changes the distance between the two ends of the elastic panel, thereby adjusting the highest position of the protrusion of the elastic panel to adapt to different user needs; further, an inclined slot 15 can be set on the base 1 and the adjustment component 3, and the two ends of the elastic panel are limited by the slot wall to prevent the end of the elastic panel from falling out of the slot during adjustment or use.

[0037] Alternatively, the buffer component 2 can be a combination of a panel and an elastic part, and the adjustment component 3 is used to adjust the active stroke of the elastic part. For example, the elastic part is a spring, and the adjustment component 3 compresses or extends the active stroke of the spring, so that the highest position of the protrusion of the entire buffer component 2 can be changed to adapt to different personalized user needs.

[0038] The adjustment assembly 3 includes a sliding portion 31 that is slidably connected to the base 1; a retaining portion 321 that connects the sliding portion 31 and the base 1, respectively, and is suitable for maintaining the relative position of the sliding portion 31 and the base 1. The two ends of the buffer assembly 2 are respectively connected to the base 1 and the sliding portion 31. The retaining portion 321 cooperates with the sliding portion 31 or the base 1 to limit the sliding of the sliding portion 31, thereby maintaining the relative position of the sliding portion 31 and the base 1.

[0039] For example, the retaining portion 321 is arranged on both sides of the sliding portion 31, and multiple gears are set along the track on the seat body 1 that is slidably connected to the sliding portion 31. The gears are engaged with the retaining portion 321. The retaining portion 321 is manually disengaged from the gear, and the above-mentioned sliding portion 31 is manually slid, and then the retaining portion 321 is engaged into another gear to complete the adjustment of the buffer assembly 2. Please refer to the structure of Example 2.

[0040] For another example, the adjustment assembly 3 also includes an adjustment member 32, which is rotatably connected to the seat body 1. Rotating the adjustment member 32 can drive the sliding part 31 to slide; the retaining part 321 is provided on the adjustment member 32, and through threaded cooperation with the seat body 1 or threaded cooperation with the sliding part 31, it drives the sliding part 31 to slide relative to the seat body 1.

[0041] Specifically, the base body 1 is provided with a mounting frame 11; the adjusting member 32 includes an operating portion 322 and a retaining portion 321, and the operating portion 322 is located on the side of the mounting frame 11 away from the base body 1; the adjusting member 32 is axially rotatably connected to the mounting frame 11, and the adjusting member 32 is threadedly connected to the sliding portion 31 through the retaining portion 321; or the adjusting member 32 is threadedly connected to the mounting frame 11 through the retaining portion 321, and one end of the adjusting member 32 is axially rotatably connected to the sliding portion 31.

[0042] In this embodiment, a mounting hole 13 is provided on the base 1, and the sliding portion 31 is connected to the mounting hole 13; the adjusting member 32 is in the shape of a screw, with an operating portion 322 provided at one end and a retaining portion 321 provided at the other end, and has a threaded structure; the adjusting member 32 is axially rotatably connected to the mounting frame 11, and preferably, the operating portion 322 is exposed from the outer wall of the base 1, and the retaining portion 321 is threadedly connected to the sliding portion 31. The operating portion 322 of the adjusting member 32 is rotated, and the sliding portion 31 is driven by the thread to slide, thereby changing the distance between the two ends of the elastic panel, thereby adjusting the highest position of the elastic panel protrusion. In addition, the threaded connection can make the adjustment process smoother and more fluid, without obvious gear differences, thereby increasing the number of adjustable gears and the accuracy.

[0043] As a simple technical replacement, in some other embodiments, the retaining portion 321 of the adjusting member 32 can be threadedly connected to the mounting frame 11, and the end of the adjusting member 32, that is, the end away from the operating portion 322, can be axially rotatably connected to the sliding portion 31, for example, fixed together by rivets, and by screwing the operating portion 322, the sliding portion 31 can be driven to slide on the base body 1.

[0044] Furthermore, the adjustment assembly 3 further includes a first bearing 33 , which is sleeved on the adjustment member 32 and located between the retaining portion 321 and the mounting bracket 11 , and is suitable for reducing friction resistance when the adjustment member 32 is rotated.

[0045] Furthermore, the adjustment assembly 3 further includes a limiter 34 , which is engaged with the adjustment member 32 and is suitable for limiting axial displacement between the adjustment member 32 and the mounting bracket 11 ; the first bearing 33 is located between the mounting bracket 11 and the limiter 34 .

[0046] In this embodiment, a through-hole is provided on the mounting frame 11 for the adjusting member 32 to pass through; the limiting member 34 is larger than the through-hole, and the limiting member 34 is installed on the side of the mounting frame 11 facing away from the operating portion 322 to limit the axial movement of the adjusting member 32. Specifically, a limiting groove is provided on the adjusting member 32, and the limiting member 34 is inserted into the limiting groove. Alternatively, a limiting groove can be provided on the limiting member 34, and a limiting protrusion can be provided on the adjusting member 32. When the adjusting member 32 is screwed, the limiting member 34 will be driven to rotate due to the friction between the limiting member 34 and the adjusting member 32, and there is also friction between the end face of the limiting member 34 and the mounting bracket 11, that is, the facing surfaces of the mounting bracket 11 and the limiting member 34, which will make it difficult for the limiting member 34 to be driven to rotate, resulting in a large amount of effort to drive the adjusting member 32, which is not friendly to students with less strength; in this case, by adding a first bearing 33 between the limiting member 34 and the mounting bracket 11, the rotational resistance between the two is reduced, which can effectively lower the threshold of the driving force and improve the smoothness of the adjustment.

[0047] In some other embodiments with less effective effects, the axial displacement of the adjusting member 32 and the mounting frame 11 can be directly limited by the first bearing 33, that is, the mounting frame 11 is located between the first bearing 33 and the operating portion 322. For example, the operating portion 322 and the retaining portion 321 are set as a separate structure and fixedly connected by fixing screws or the like. Before the two are fixed, the retaining portion 321 is sequentially passed through the first bearing 33 and the through-hole of the mounting frame 11 and then fixed to the operating portion 322, or the operating portion 322 is sequentially passed through the through-hole of the mounting frame 11 and the first bearing 33 and then fixed to the retaining portion 321, so that the first bearing 33 is located between the retaining portion 321 and the mounting frame 11; thereby, the rotational friction resistance between the operating portion 322 and the mounting frame 11 is reduced by the first bearing 33.

[0048] Furthermore, the adjusting member 32 and the limiting member 34 are axially rotatable, that is, the adjusting member 32 can rotate axially within the limiting member 34, which is suitable for further reducing frictional resistance when tightening the adjusting member 32. Specifically, in this embodiment, the limiting member 34 is provided with a connecting groove. During assembly, the adjusting member 32 is installed on the adjusting member 32 through the notch of the connecting groove. At this time, the adjusting member 32 is inserted into the connecting groove. The aperture of the connecting groove is set to be larger than the diameter of the bottom surface of the limiting groove on the adjusting member 32, and smaller than the diameter of the highest point of the limiting groove.

[0049] Preferably, the first bearing 33 is a ball bearing, and the opposing surfaces of the mounting bracket 11 and the limiting member 34 are also in contact with the ball bearing.

[0050] Furthermore, a second bearing 35 is included, which is connected to the base body 1 and sleeved onto the end of the adjusting member 32 distal from the operating portion 322, thereby connecting both ends of the adjusting member 32 to the base body 1. This increases the structural stability of the adjusting member 32 while reducing frictional resistance between the distal end of the adjusting member 32 and the base body 1. In this embodiment, the mounting frame 11 extends to the end of the mounting hole 13 distal from the operating portion 322, forming a frame-like mounting frame 11 at the lower end of the mounting hole 13. The first bearing 33 and the second bearing 35 are respectively disposed on the mounting frame 11, located proximal and distal to the operating portion 322, respectively. A bearing groove for securing the second bearing 35 is provided on the mounting frame 11.

[0051] A mounting through hole 13 is provided on the base body 1; a slide rail portion 12 is provided on the base body 1 and is located in the mounting through hole 13; a sliding block 311 is provided on the sliding portion 31 and cooperates with the slide rail portion 12; a notch 14 is provided at one end of the slide rail portion 12, which is suitable for assembling the sliding portion 31 to the slide rail portion 12.

[0052] In this embodiment, the rail portion 12 is disposed at the lower end of the mounting hole 13, the notch 14 is located on the side of the rail portion 12 away from the operating portion 322, and the mounting bracket 11 is located below the rail portion 12 on the side closer to the operating portion 322. An inclined slot 15 is provided on the sliding portion 31. The sliding portion 31 is assembled to the rail portion 12 through the notch 14, and one end of the sliding portion 31 with the slot passes through the mounting hole 13.

[0053] The cushioning assembly 2 comprises an elastic panel; one end of the panel engages the base 1, and the other end engages the sliding portion 31. Both the base 1 and the sliding portion 31 are provided with inclined slots, located on either side of the base 1, to retain the ends of the elastic panel. By rotating the adjusting member 32, the sliding portion 31 moves axially along the adjusting member 32, changing the distance between the ends of the elastic panel and thereby adjusting the height of the elastic panel's center portion to suit different body shapes or individual preferences.

[0054] Furthermore, it also includes a timing component 4 connected to the base body 1.

[0055] like Figure 7 As shown, the timing component 4 includes a power module 42; a control module 41, electrically connected to the power module 42; an input module 44, electrically connected to the control module 41, suitable for inputting timing information to the control module 41; and a reminder module 45, electrically connected to the control module 41, suitable for sending a reminder signal when the timing ends.

[0056] Preferably, the timing component 4 further includes a display module 43 for conveniently observing the duration or performing operation selections on the timing component 4 .

[0057] In this embodiment, the input module 44 is provided with a button, and different input information is defined by the length of time the button is pressed. For example, a long press for 3 seconds is a power on / off operation, and a short press is for selecting a timing duration, etc. This can be achieved through the built-in program of the control module 41. These functions can be achieved by existing technologies and will not be described in detail here.

[0058] When in use, long press the button of the input module 44 to turn on the device, and use the button to select the relaxation time, such as 15 minutes or 20 minutes; after the control module 41 receives the information input by the button, it starts timing, and when the timing ends, it outputs the execution data to the reminder module 45; finally, the reminder module 45 emits an alarm sound or vibration to remind the user that the timing has ended.

[0059] The above-mentioned timing component 4 includes but is not limited to using an external finished component directly installed in the preset installation groove of the base body 1, and can also be assembled on the base body 1 in a dispersed manner. As long as it has the above-mentioned functions, it should not be considered as a limitation here.

[0060] Example 2

[0061] As a variation of the above embodiment, the position of the sliding portion 31 is fixed by combining a shift block and a shift groove.

[0062] Specifically, a plurality of shift grooves are provided on the hole wall or hole edge of the above-mentioned mounting through hole 13. The above-mentioned retaining portion 321 is a shift block provided on the sliding portion 31. The shift block is manually inserted into or pulled out of the shift groove. For example, when the position of the sliding portion 31 needs to be adjusted, the sliding portion 31 is pulled to drive the shift block out of the shift groove. Then, after adjusting the horizontal position of the sliding portion 31, the sliding portion 31 is pressed again to make the shift block inserted into the shift groove, thereby maintaining the position of the sliding portion 31 after adjustment.

[0063] Furthermore, it also includes a reset member, which is arranged between the sliding part 31 and the base body 1, and is used to keep the gear block on the sliding part 31 stuck in the gear slot, so that after adjusting the position of the sliding block 311, there is no need to manually insert the gear block into the gear slot, which simplifies the operation and improves the user experience.

[0064] The utility model discloses an adjustable lumbar vertebra relief device, which changes the stroke of the buffer component by setting an adjustment component, thereby adjusting the elasticity of the buffer component to meet the personalized needs of different users, thereby effectively helping users relax and relieve their waists, and further helping students prevent and improve hunchbacks.

[0065] The above embodiments only represent a part of the implementation methods of the present invention. Any modifications, substitutions and improvements made by those skilled in the art without creative work without departing from the concept of the present invention shall fall within the scope of protection of the present invention.
