[0037] Reference Figure 1-5 The figure shows a preferred embodiment of the present invention.

[0038] The height-adjustable damping structure includes a frame 100 arranged in a longitudinal strip shape, the frame 100 has a groove 101 inside, the groove 101 is extended along the height direction of the frame 100, and the groove 101 is provided with a movable seat 200 that moves up and down along the height direction of the frame 100; that is, the groove 101 is also extended longitudinally, and after the movable seat 200 moves up and down along the groove 101, the height adjustment of the movable seat 200 on the frame 100 is realized.

[0039] The movable seat 200 is provided with a transverse shaft which is arranged to move laterally. The middle of the transverse shaft has a middle section 302 which penetrates the movable seat 200 . The two sections of the transverse shaft have outer sections 301 which extend outside the movable seat 200 respectively.

[0040] The movable seat 200 includes a damping ring 400 with adjustable tightness, and the damping ring 400 is wrapped around the outer periphery of the middle section 302. When the transverse axis rotates relative to the movable seat 200, the damping ring 400 applies a circumferential damping force to the middle section 302. The tightness of the damping ring 400 can be adjusted, so that the force with which it is wrapped around the middle section 302 can be adjusted, thereby achieving adjustable magnitude of the damping force applied to the outer periphery of the middle section 302.

[0041] The outer section 301 is sleeved with a one-way gear 205 that rotates unidirectionally relative to the transverse axis. The inner side wall of the groove 101 has two meshing side walls 102 arranged at intervals. The two meshing side walls 102 are arranged opposite to the two one-way gears 205 respectively, and the one-way gears 205 mesh with the meshing side walls 102.

[0042] When the movable seat 200 moves downward relative to the frame 100, the one-way gear 205 is relatively fixed to the transverse shaft, the transverse shaft rotates relative to the movable seat 200, the damping ring 400 applies a circumferential damping force to the transverse shaft, and the one-way gear 205 rotates synchronously with the transverse shaft and moves downward in meshing engagement along the meshing side wall 102;

[0043] When the movable seat 200 moves upward relative to the frame 100 , the transverse shaft and the movable seat 200 are relatively fixed, and the one-way gear 205 rotates unidirectionally relative to the transverse shaft and moves upward along the meshing side wall 102 .

[0044] In the height adjustment damping structure provided above, the middle section 302 of the transverse axis is wrapped with a damping ring 400, and the damping ring 400 can be adjusted in tightness to adjust the damping force applied to the middle section 302. During the downward movement of the movable seat 200 along the groove 101, due to the unidirectional rotation restriction of the one-way gear 205, the transverse axis overcomes the damping force and rotates to realize the downward movement of the movable seat 200. During the upward movement of the movable seat 200 along the groove 101, the one-way gear 205 can rotate unidirectionally to realize the upward movement of the movable seat 200, thereby realizing the height adjustment of the movable seat 200 relative to the frame 100, and realizing adjustable damping force, which is convenient for height adjustment and can be adapted to different usage requirements.

[0045] In actual use, the damping force of the damping ring 400 can be increased to limit the downward movement of the movable seat 200 relative to the frame 100. In this way, the movable seat 200 can play a load-bearing role. The damping force is adjusted accordingly according to the weight of the load, which greatly simplifies the position fixing structure after the height adjustment.

[0046] During use, when the moving seat 200 moves upward, since the one-way gear 205 can rotate in one direction, no damping force will be generated. The force required for the moving seat 200 to move upward is only to overcome the self-weight of the moving seat 200. When the moving seat 200 moves downward, the one-way gear 205 will not rotate in one direction. It rotates synchronously with the transverse axis to generate a damping force. The damping force can offset the self-weight of the moving seat 200, so that the moving seat 200 will not fall.

[0047] In this embodiment, the outer section 301 is connected with a one-way bearing 206 that rotates in one direction relative to the outer section 301, and the one-way gear 205 is sleeved on the one-way bearing 206 and fixed relative to the one-way bearing 206. The one-way bearing 206 can only rotate in one direction and is locked in other directions. The one-way gear 205 is fixedly sleeved on the one-way bearing 206 and has the same one-way rotation characteristic as the one-way bearing 206.

[0048] In this embodiment, a rear guide channel is provided on the inner side wall of the groove 101, and the rear guide channel is extended along the height direction of the frame 100. The rear guide channel is arranged between the two engaging side walls 102, and the rear guide channel guides the movable seat 200 to move along the groove 101; the rear end protrusion of the movable seat 200 is formed with a rear protrusion strip 201, and the rear protrusion strip 201 is movably embedded in the rear guide channel.

[0049] The rear raised strip 201 is provided with a rear downward roller 202, which abuts against the inner wall of the groove 101. When the movable seat 200 moves along the groove 101, the rear raised strip 201 moves along the rear guide path, and the rear downward roller 202 rolls along the rear guide path.

[0050] By arranging the rear raised strip 201, and the rear raised strip 201 is movably embedded in the rear guide channel, when the movable seat 200 moves up and down in the channel 101, the movement of the movable seat 200 can be guided to maintain the stability of the movement of the movable seat 200. In addition, by arranging the rear downward roller 202, the rear downward roller 202 can abut against the inner side wall of the channel 101 to achieve rolling abutment, thereby maintaining the stability and smoothness of the upward and downward movement of the movable seat 200 in the channel 101.

[0051] In this embodiment, two rear convex walls 104 are protruding on the inner side wall of the groove 101, and the two rear convex walls 104 and the inner side wall of the groove 101 form the above-mentioned rear guide channel. The inner side wall of the groove 101 has a rear guide side wall 103 located between the two rear convex walls 104, and the rear downward roller 202 abuts against the rear guide side wall 103; the two sides of the rear raised strip 201 respectively abut against the two rear convex walls 104, and there is a guiding gap between the end of the rear raised strip 201 and the rear guide side wall 103.

[0052] The two sides of the rear raised strip 201 are respectively abutted against the two rear raised walls 104, thereby realizing the longitudinal guidance of the moving seat 200 in the groove 101. There is a guiding gap between the end of the rear raised strip 201 and the rear guide side wall 103, and the rear downward roller 202 is abutted against the rear guide side wall 103, so that the smoothness and stability of the moving seat 200 in the groove 101 can be maintained.

[0053] In this embodiment, a guide bearing 207 is connected to the outer section 301 , and the guide bearing 207 abuts against the end of the rear convex wall 104 . When the movable seat 200 moves along the groove 101 , the guide bearing 207 moves along the end of the rear convex wall 104 .

[0054] By arranging the guide bearing 207, the guide bearing 207 can rotate in both directions, and it abuts on the rear convex wall 104. When the moving seat 200 moves in the groove 101, the guide bearing 207 abuts against the rear convex wall 104 and moves. In this way, at the rear end of the moving seat 200, a rear downward roller 202, two one-way gears 205 and two guide bearings 207 are formed for positioning, abutment and guidance, and are arranged along the width direction of the moving seat 200, thereby realizing multi-position positioning and guiding of the rear end of the moving seat 200, so that the moving seat 200 can move smoothly and stably in the groove 101.

[0055] In this embodiment, the inner side wall of the groove 101 has two front guide side walls 105 respectively arranged opposite to the meshing side walls 102, and the lower part of the front end of the movable seat 200 is provided with two front upward rollers 204, and the two front upward rollers 204 are arranged laterally at intervals, and the two rear downward rollers 202 are arranged at the lower part of the rear raised strip 201, and the two front upward rollers 204 and the two rear downward rollers 202 are arranged laterally opposite to each other.

[0056] During the upward movement of the moving seat 200 along the channel 101, the front upward roller 204 is pressed against the front guide side wall 105 by force and rolls along the front guide side wall 105, and the one-way gear 205 presses against the meshing side wall 102. When the moving seat 200 moves upward in the channel 101, the moving seat 200 has a tendency to swing backward. At this time, the front upward roller 204 presses against the front guide side wall 105 to withstand the swinging force of the moving seat 200 during the upward movement, so as to keep the moving seat 200 moving upward smoothly in the channel 101.

[0057] In this embodiment, two front downward moving rollers 203 are provided at the upper part of the front end of the movable seat 200, and the two front downward moving rollers 203 are arranged laterally at intervals. The rear downward moving roller 202 is set at the lower part of the rear raised strip 201, and is arranged opposite to the two front downward moving rollers 203 at an inclined diagonal angle.

[0058] When the movable seat 200 moves downward along the groove 101 , the rear downward roller 202 is pressed against the rear guide side wall 103 and rolls along the rear guide side wall 103 , and the front downward roller 203 is pressed against the front guide side wall 105 and rolls along the front guide side wall 105 .

[0059] When the movable seat 200 moves upward along the channel 101 , the rear downward roller 202 is released from pressing against the rear guide side wall 103 , and the front downward roller 203 is released from pressing against the front guide side wall 105 .

[0060] When the moving seat 200 moves downward in the groove 101, the moving seat 200 has a tendency to swing forward. At this time, since the one-way gear 205 is in a one-way locked rotation, the transverse axis is in a state of rotating to overcome the damping force, the front downward roller 203 is pressed against the front guide side wall 105, and the rear downward roller 202 is pressed against the rear guide side wall 103, which is used to withstand the swinging force of the moving seat 200 during the downward movement to keep the moving seat 200 moving smoothly downward.

[0061] In this embodiment, the movable seat 200 has a transversely penetrating mounting hole, the middle section 302 is inserted into the mounting hole, and the damping ring 400 abuts against the inner wall of the mounting hole; the damping ring 400 is flat so that the damping ring 400 can be wrapped around the outer periphery of the middle section 302 in a larger range, and the damping ring 400 is made of nylon elastomer so that the damping ring 400 can be elastically deformed and the tightness of the damping ring 400 wrapped around the middle section 302 can be adjusted to achieve the adjustment of the damping force applied by the damping ring 400 on the middle section 302.

[0062] The damping ring 400 has a disconnected notch 401 , and has a deformation section 402 arranged opposite to the disconnected notch 401 . Two sections of the deformation section 402 extend outwards respectively to form extension sections 403 . The two extension sections 403 are disconnected to form the above-mentioned disconnected notch 401 .

[0063] An elastic sheet is connected to the deformation section 402, and arc-shaped fixed sections 502 are extended outward at both ends of the elastic sheet. The fixed sections 502 are bent along the circumferential arc of the damping ring 400 and are immersed in and fixed inside the deformation section 402; an arc-shaped arc section 501 is formed in the middle of the elastic sheet, and the arc section 501 is bent along the circumferential arc of the damping ring 400. The arc section 501 and the deformation section 402 are arranged at an interval to form an elastic interval 405.

[0064] The movable seat 200 has a through hole, which penetrates to the outside of the movable seat 200 and is aligned and communicated with the arc segment 501; a top shaft is provided in the through hole, and the top shaft presses against the middle of the arc segment 501; an elastic column 700 is provided in the elastic spacer 405, and the outer section of the elastic column 700 is fixedly abutted against the middle of the arc segment 501, and the inner section of the elastic column 700 is fixedly abutted against the middle of the deformation segment 402; along the direction from the arc segment 501 to the deformation segment 402, the diameter of the elastic column 700 gradually increases, and the inside of the elastic column 700 is hollowed out, and the elastic column 700 is in a compressed state;

[0065] By adjusting the pressure of the top shaft on the arc segment 501, the elastic sheet is elastically deformed, driving the damping ring 400 to compress and deform or restore the deformation.

[0066] When the top shaft increases the pressure on the arc segment 501, the elastic sheet deforms toward the damping ring 400, driving the damping ring 400 to clamp the middle segment 302 to increase the damping force applied to the middle segment 302. When the top shaft reduces the pressure on the arc segment 501, the elastic sheet moves away from the damping ring 400 and recovers its deformation. The damping ring 400 reduces its clamping on the middle segment 302 to reduce the damping force applied to the middle segment 302.

[0067] The damping ring 400 has a disconnected notch 401, which is convenient for adjusting the tightness of the damping ring 400. By arranging the elastic column 700, the elastic column 700 is deformed synchronously with the deformation of the elastic sheet. In the process of the elastic sheet driving the damping ring 400 to deform, the elastic column 700 synchronously drives the damping ring 400 to deform, thereby realizing multi-position and multi-power driving of the damping ring 400. In addition, the elastic column 700 is set in the middle of the elastic interval 405, which can enable the elastic sheet to better drive the damping ring 400 to circumferentially deform toward the middle section 302.

[0068] In addition, arc-shaped fixed sections 502 extend outward from both ends of the elastic sheet. The fixed sections 502 are bent along the circumferential arc of the damping ring 400 and are inserted and fixed inside the deformation section 402. In this way, when the elastic sheet is compressed and deformed, the circumferential deformation of the damping ring 400 toward the middle section 302 can be better guided by the fixed sections 502.

[0069] In this embodiment, a plurality of elastic inclined pieces 601 are provided in the elastic spacer 405, and the plurality of inclined pieces 601 are arranged in sequence and at intervals, and are respectively arranged on both sides of the elastic column 700; the outer ends of the inclined pieces 601 are fixedly docked on the arc segment 501, and the inner ends of the inclined pieces 601 are bent to form bent pieces 602, and the bent pieces 602 are fixedly docked on the surface of the deformation segment 402; along the direction from the arc segment 501 to the deformation segment 402, the inclined pieces 601 are tilted and arranged away from the elastic column 700;

[0070] A plurality of flexible strips 404 are built into the interior of the damping ring 400. The flexible strips 404 are arranged along the circumferential extension of the damping ring 400. The plurality of flexible strips 404 are arranged at intervals and staggered along the width direction of the damping ring 400, and are arranged at intervals and staggered along the thickness direction of the damping ring 400. When the elastic sheet elastically deforms and drives the damping ring 400 to compress and deform or recover, the plurality of flexible strips 404 guide the damping ring 400 to elastically deform along the circumference of the middle section 302.

[0071] By arranging multiple inclined plates 601 in an inclined manner, when the elastic plate is compressed and deformed, the multiple inclined plates 601 are also deformed synchronously, and the damping ring 400 can be driven to deform circumferentially toward the middle section 302. The inner end of the inclined plate 601 forms a bending plate 602, which is fixed on the surface of the deformation section 402, and cooperates with the fixed section 502 of the elastic plate to be built into the interior of the deformation section 402, so that the damping ring 400 can be driven to deform circumferentially toward the middle section 302 synchronously inside and outside.

[0072] In this embodiment, an arc groove 408 is provided on the inner wall of the extension section 403, and the arc groove 408 passes through the disconnected notch 401. An arc track is protruded on the middle section 302, and the arc track passes under the disconnected notch 401, and the arc track is movably embedded in the arc groove 408. In this way, when the damping ring 400 is in the process of compression deformation or recovery deformation, the damping ring 400 can be deformed circumferentially along the middle section 302 by utilizing the guiding cooperation between the arc track and the arc groove 408.

[0073] In addition, the embedded fit between the arc track and the arc groove 408 can increase the fitting area between the damping ring 400 and the middle section 302, and can achieve a wider range of damping force adjustment.

[0074] In addition, in order to achieve better compression deformation and recovery deformation of the damping ring 400, the interior of the damping ring 400 is filled with an elastic ring 407. The elastic ring 407 is made of elastic rubber, which is built into the interior of the damping ring 400 and extended along the circumferential direction of the damping ring 400. When the damping ring 400 is compressed, the elastic ring 407 is also compressed and deformed. When the damping ring 400 recovers the deformation, the elastic ring 407 also recovers the deformation, and the deformation of the elastic ring 407 is greater than the deformation of the damping ring 400. Therefore, the elastic ring 407 can enhance the elastic deformation function of the damping ring 400, so that it maintains its elastic characteristics, and the damping force of the damping ring 400 can be adjusted in a wider range.
