Description

Technical Field

[0001] The utility model generally relates to the technical field of household products, and in particular to an adjustment mechanism and a support device. Background Art

[0002] Existing household items such as beds, tables, chairs, and cabinets are typically supported by support mechanisms to accommodate different scenarios. However, these traditional support mechanisms require a specific height to be confirmed at the time of purchase and cannot be changed during subsequent use, making them unable to accommodate the varying height requirements of household items in real life.

[0003] In order to solve this problem, the existing technology adopts the following methods:

[0004] 1. A threaded structure is set on the top of the support mechanism to facilitate installation and disassembly. However, this vertical connection method can only be completed by disassembly when storing or transporting, and the support mechanism does not have the function of folding;

[0005] 2. The height can be adjusted by rotating the expansion piece, but before adjusting the height, the furniture must be turned upside down to provide space for the support mechanism to extend further downward, which is a complicated operation.

[0006] 3. A spring is placed inside the support mechanism and fixed with a pin. The spring will be in a compressed state for a long time during use. The spring's fatigue resistance decreases after long-term use. When adjusting other heights, the spring's supporting force is insufficient, affecting the user experience. Utility Model Content

This facilitates switching between different gear positions and improves the convenience of position adjustment.

[0043] The locking assembly can be unlocked and locked by simply pressing it, which is simple to operate and simplifies the user's operation steps, saving time and effort, and improving user satisfaction. The pressing direction of the locking assembly is the same as the threading direction of the locking assembly, which is more in line with user operating habits and further improves ease of use. The pressing force on the locking assembly is directly converted into the unlocking driving force of the locking assembly. There are no intermediate force transmission components and changes in force transmission direction. The unlocking process responds quickly and is highly reliable. BRIEF DESCRIPTION OF THE DRAWINGS

Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0073] Example 1

[0074] This embodiment provides a supporting device, such as Figure 1As shown, the supporting device includes a supporting structure 200 and an adjusting mechanism 100 . The adjusting mechanism 100 is connected to the supporting structure 200 and is used to adjust the position of the supporting structure 200 .

[0075] Exemplarily, the support structure 200 may be a planar structure. For example, the support structure 200 may be a bed frame, a table board, or a chair seat board. The support device may specifically be furniture such as a bed, a table, or a chair.

[0076] Exemplarily, the adjustment mechanism 100 can be specifically a support leg, which is connected to the support structure 200. The adjustment mechanism 100 has a telescopic function and is used to adjust the height of the support structure 200; or, the adjustment mechanism 100 and the support structure 200 are rotatably connected, and the adjustment mechanism 100 is used to adjust the angle of the support structure 200; or, the support leg directly supports the support structure 200, and the adjustment mechanism 100 is arranged between the support leg and the support structure 200, and the adjustment mechanism 100 realizes the folding and unfolding of the support structure 200.

[0077] In one embodiment, a connecting component 101 is provided on the side of the adjustment mechanism 100 facing the support structure 200. The adjustment mechanism 100 is rotatably connected to the support structure 200 through the connecting component 101. The adjustment mechanism 100 serves as a supporting member such as a supporting leg to realize the free folding and unfolding of the support structure 200, thereby achieving the effect of storage and volume reduction.

[0078] Specifically, the connecting component 101 includes a connecting member and a rotating shaft. The connecting member is a sheet-like structure, and the cross-section of the connecting member is an L-shaped structure. One end of the connecting member is connected to the adjustment mechanism 100, and the other end is rotatably connected to the support structure 200, so that the connecting member and the support structure 200 are hinged. The support structure 200 rotates relative to the connecting member through the rotating shaft, which is convenient for folding and unfolding.

[0079] This embodiment also provides an adjustment mechanism 100, such as Figure 2-Figure 4 As shown, the adjustment mechanism 100 includes a first support member 1, a second support member 2, and a locking assembly 3. The first support member 1 and the second support member 2 are slidably engaged. One of the first support member 1 and the second support member 2 is provided with a slideway 21, and the other is provided with a fixing hole 11. The slideway 21 includes a slide groove 211 and a plurality of positioning holes 212. The plurality of positioning holes 212 are arranged along the extension direction of the slideway 21, and adjacent positioning holes 212 are connected by the slide groove 211. The locking assembly 3 is provided along the axial direction of the locking assembly 3 and extends through the fixing hole 11 and one of the positioning holes 212.

[0080] Among them, the axial direction of the locking assembly 3 is the first direction, which can be marked with D1, the extension direction of the slide 21 is the second direction, which can be specifically the vertical direction or the horizontal direction, which can be marked with D2, and the width direction of the slide 21 is the third direction, which can be marked with D3. The axial direction of the locking assembly 3, the extension direction of the slide 21, and the width direction of the slide 21 are perpendicular to each other. These three directions only represent spatial directions and have no substantive meaning. It is understandable that as the first support member 1 and the second support member 2 rotate, the positions of the slide 21 and the locking assembly 3 set on the support members will also change in three-dimensional space. Although these three directions will also change accordingly, the perpendicular relationship between the three directions will not change.

[0081] The locking assembly 3 is configured to be pressed along the axial direction of the locking assembly 3 so that the locking assembly 3 can slide along the sliding groove 211 for switching the first support member 1 and the second support member 2 between the locked state and the unlocked state.

[0082] When the locking assembly 3 is inserted through the slideway 21 and the fixing hole 11, the locking assembly 3 realizes the connection between the first support member 1 and the second support member 2. The locking assembly 3 is fixed relative to the fixing hole 11. The locking assembly 3 is in a locked state, and the first support member 1 and the second support member 2 cannot move relative to each other, so that the support structure 200 remains stable at this height position. After pressing the locking assembly 3 in the axial direction of the locking assembly 3, the locking assembly 3 can slide along the slideway 21. The slideway 21 plays a guiding and path planning role for the locking assembly 3. The locking assembly 3 is in an unlocked state, and the first support member 1 and the second support member 2 can slide relative to each other. As the first support member 1 and the second support member 2 extend or contract, the position of the support structure 200 is adjusted.

[0083] Because the multiple positioning holes 212 are arranged along the extension direction of the slideway 21 and correspond to different positions, the adjustment mechanism 100 has a multi-gear adjustment function. The locking assembly 3's fixing hole 11 is aligned with any of the positioning holes 212 to lock different gear positions and maintain stability in each gear position. Adjacent positioning holes 212 are connected by a slide slot 211, allowing the locking assembly 3 to slide directly from the positioning hole 212 into the slide slot 211, ensuring seamless and smooth switching between the folded and unfolded states. This facilitates switching between different gear positions and improves the convenience of position adjustment.

[0084] The locking assembly 3 can be unlocked and locked by simply pressing it, which is simple to operate, simplifies the user's use process, saves time and effort, and improves user satisfaction. The pressing direction of the locking assembly 3 is the same as the insertion direction of the locking assembly 3, which is more in line with the user's operating habits and further improves the convenience of use. The pressing force on the locking assembly 3 can be directly converted into the unlocking driving force of the locking assembly 3. There are no intermediate force transmission components and changes in the force transmission direction. The unlocking process responds quickly and is highly reliable.

[0085] It can be understood that as the first support member 1 extends or contracts relative to the second support member 2, the first support member 1 and / or the second support member 2 are connected to the support structure 200, and the relative position of the support structure 200 will also change. The first support member 1 and / or the second support member 2 are rotatably connected to the support structure 200 through the connecting assembly 101 to compensate for the position change.

[0086] It can be understood that if the second direction is the vertical direction, as the first support member 1 extends or contracts relative to the second support member 2, the adjustment mechanism 100 is used to adjust the height position of the support structure 200; of course, the second direction can also be the horizontal direction or other directions, and the adjustment mechanism 100 is used to adjust the position of the support structure 200 in this direction. This embodiment takes height adjustment as an example, and the adjustment principles in other directions are similar, so they will not be described in detail.

[0087] The first support member 1 and the second support member 2 extend along the second direction and are specifically rod-shaped structures. The shapes of the two support members are compatible and consistent. Specifically, the lengths of the first support member 1 and the second support member 2 along the second direction can be approximately the same, and the widths of the first support member 1 and the second support member 2 along the third direction can be approximately the same. When in the retracted state, the first support member 1 and the second support member 2 overlap after being shortened, saving space.

[0088] The first support member 1 and the second support member 2 can both be tubular structures, and the first support member 1 and the second support member 2 can be nested within each other. Specifically, the first support member 1 and the second support member 2 have the same cross-sectional shape, which can be rectangular, circular, or other shapes. For example, the first support member 1 and the second support member 2 provided in this embodiment can be square tubes or circular tubes. In this embodiment, a circular tube is used as an example, and the first support member 1 and the second support member 2 both have circular cross-sectional structures.

[0089] Specifically, if Figure 3-Figure 4As shown, the first support member 1 can be called an outer tube, the second support member 2 can be called an inner tube, the second support member 2 is slidably arranged in the first support member 1, the first support member 1 is provided with a fixing hole 11, and the second support member 2 is provided with a slide 21. Of course, the positions of the fixing hole 11 and the slide 21 can also be interchanged. For example, the slide 21 is provided on the first support member 1, and the fixing hole 11 is provided on the second support member 2. The specific structure and principle are similar, so they will not be described in detail.

[0090] In another embodiment, the number of the slide groove 211 may be one, and the positioning hole 212 is provided on at least one side of the slide groove 211 along the extension direction of the slideway 21. It is understandable that the number of the slide groove 211 may also be one, and the number of the positioning holes 212 may be two, and the two positioning holes 212 are respectively provided at both ends of the slide groove 211, so that the first support member 1 and the second support member 2 can maintain good position stability in both the extended state and the retracted state.

[0091] In another embodiment, there are at least two slide grooves 211, and one positioning hole 212 is provided at at least one end of the slide 21 along its extension direction, and two adjacent slide grooves 211 are connected by another positioning hole 212. That is, the positioning hole 212 is provided in the middle of the slide 21, so that the middle position and the end position of the slide 21 have a locking position, thereby increasing the adjustment range.

[0092] It is understandable that the number of positioning holes 212 provided in this embodiment can also be greater than two. For example, the number of positioning holes 212 is four, the number of slide grooves 211 is three, and the four positioning holes 212 are arranged along the second direction. For example, the first positioning hole 212 is set on the side of the slide groove 211 away from the support structure 200, that is, the positioning hole 212 is located below the slide groove 211. When the first support member 1 and the second support member 2 move toward each other, the first support member 1 and the second support member 2 are shortened, and the locking assembly 3 is passed through the positioning hole 212 and the fixing hole 11 at the lowest height position. At this time, it is the locked position at the lowest height position to ensure the stability of the support structure 200 at the lowest height position. Of course, the second positioning hole 212 is set on the side of the slide 211 close to the support structure 200, that is, the positioning hole 212 is located above the slide 211. When the first support member 1 and the second support member 2 move away from each other, the first support member 1 and the second support member 2 extend, and then the locking assembly 3 is inserted into the positioning hole 212 and the fixing hole 11 at the top. This is the locking position at the highest height position to ensure the stability of the support structure 200 at the highest height position. The third positioning hole 212 and the fourth positioning hole 212 are set between the first positioning hole 212 and the second positioning hole 212. The two adjacent positioning holes 212 are connected by the slide 211. These four positioning holes 212 correspond to four different height positions, so that the first support member 1 and the second support member 2 can maintain good position stability at different height positions.

[0093] In one embodiment, Figure 4 As shown, the positioning holes 212 are symmetrically arranged relative to the axis direction of the sliding groove 211.

[0094] That is, the positioning hole 212 is not eccentrically arranged relative to the slide groove 211, but the axis of the slide groove 211 passes through the center of the positioning hole 212. The transition between the slide groove 211 and the positioning hole 212 is smooth and without corners. During use, the user does not need to lift or press down the locking component 3 in the third direction. The locking component 3 can slide smoothly and smoothly between the positioning hole 212 and the slide groove 211. It is easy to operate and use, and reduces the risk of jamming during state switching.

[0095] Since the first support member 1 and the second support member 2 need to slide against each other during the adjustment process, if the inner wall of the first support member 1 and the outer wall of the second support member 2 are tightly fitted, it will affect the smoothness of the sliding of the first support member 1 and the second support member 2; if there is a gap between the first support member 1 and the second support member 2, noise and abnormal sounds will occur during the adjustment or actual use process, affecting the user experience.

[0096] For this reason, Figure 4-Figure 5As shown, the adjustment mechanism 100 further includes a fastener 4. A gap is provided between the first support member 1 and the second support member 2. The fastener 4 is disposed within the gap, and one of the first support member 1 and the second support member 2 is slidably engaged with the fastener 4. The fastener 4 is used to fill the gap between the inner wall of the first support member 1 and the outer wall of the second support member 2, thereby strengthening the connection and preventing shaking when adjusting to different heights, thereby improving the user experience.

[0097] It can be understood that when the first support member 1 and the second support member 2 are both tube structures, the fastener 4 is also a sleeve structure, and the fastener 4 can also be called a fastening sleeve. The fastener 4 is sleeved on the outside of the second support member 2 and is arranged between the first support member 1 and the second support member 2.

[0098] In the extension direction of the slideway 21 , the length of the fastener 4 is smaller than the length of the first support member 1 .

[0099] With this arrangement, the fastener 4 does not extend to the entire first support member 1. The fastener 4 only fills a portion of the gap between the first support member 1 and the second support member 2 along the second direction, so that the inner and outer side walls of the fastener 4 press against the first support member 1 and the second support member 2 respectively, increasing the connection tightness. However, since the first support member 1 and the second support member 2 also have another portion of the gap, this portion of the gap can be utilized to ensure the smoothness of the relative sliding of the first support member 1 and the second support member 2. Therefore, it can simultaneously take into account the effects of reducing noise, abnormal noise and facilitating sliding adjustment.

[0100] Among them, such as Figure 4-Figure 5 As shown, the outer wall of the fastener 4 is provided with a reinforcing rib 43, which can increase the structural strength of the fastener 4. At the same time, the reinforcing rib 43 is a convex rib structure, and the side of the reinforcing rib 43 away from the second support member 2 can abut against the inner wall of the first support member 1, further increasing the tightness between the first support member 1 and the second support member 2.

[0101] If the first support member 1 is mounted on the outside of the second support member 2, and the bottom of the first support member 1 is an open structure, the edge of the open structure may scratch the user when the user adjusts the first support member 1 to slide relative to the second support member 2, resulting in poor safety.

[0102] To solve this problem, Figure 4-Figure 5As shown, along the extension direction of the slideway 21, a bearing portion 42 is provided at the bottom of the fastener 4. The bearing portion 42 can be an annular boss provided on the outer wall of the fastener 4. The bearing portion 42 can block the bottom opening structure of the first support member 1, preventing the sharp edges of the opening structure from scratching the user, thereby improving safety. At the same time, the bearing portion 42 is used to support the first support member 1, wherein the first support member 1 is the support member located on the outside of the first support member 1 and the second support member 2. The bearing portion 42 can provide a certain supporting force for the first support member 1, allowing the fastener 4 and the first support member 1 to slide synchronously relative to the second support member 2, reducing noise and abnormal sounds during the adjustment process.

[0103] In one embodiment, Figure 4-Figure 5 As shown, the fastener 4 is provided with an avoidance groove 41 corresponding to the locking assembly 3 . The avoidance groove 41 is an opening provided on the side of the fastener 4 facing the slideway 21 . The avoidance groove 41 is used to avoid the locking assembly 3 .

[0104] By providing an avoidance groove 41 on the fastener 4, the avoidance groove 41 can give way to the locking assembly 3, so that the slide 21 can extend from the second support member 2 to the fastener 4, increasing the coverage range of the slide 21 in the second support member 2 and improving the overall height adjustment range of the adjustment mechanism 100.

[0105] In one embodiment, Figure 4 and Figure 6 As shown, the adjustment mechanism 100 further includes a base 5, which is disposed on the second support member 2 along the extension direction of the slideway 21. The second support member 2 is the support member located on the inner side of the first support member 1 and the second support member 2. By plugging the base 5 into the bottom of the second support member 2, the base 5 can directly contact the ground during use, providing good support and preventing the user from being scratched by the second support member 2 during height adjustment.

[0106] In one embodiment, Figure 7 As shown, the locking assembly 3 includes a locking member 31, and the locking member 31 includes a guide portion 311 and a locking portion 312. The guide portion 311 and the locking portion 312 are interconnected and coaxially arranged. The guide portion 311 can be inserted into the slide groove 211 and slidably cooperate with the slide groove 211. The locking portion 312 can be inserted into the positioning hole 212 and the fixing hole 11.

[0107] Since the slide 21 has two parts, the slide groove 211 and the positioning hole 212, the guide part 311 and the locking part 312 of the locking member 31 correspond to these two parts respectively. During the adjustment process, the guide part 311 of the locking member 31 can slide in the slide groove 211 until it reaches the positioning hole 212. The guide part 311 and the locking part 312 are coaxially arranged. When the locking member 31 is pressed along the first direction, the locking part 312 will fall into the positioning hole 212, completing the locking action and forming a stable supporting effect.

[0108] It is understood that the outer contours of the locking portion 312 and the positioning hole 212 are compatible. For example, the locking portion 312 may be cylindrical and the positioning hole 212 may be circular. Alternatively, the locking portion 312 may be a rectangular parallelepiped and the positioning hole 212 may be square. Of course, the locking portion 312 and the positioning hole 212 may also have other structures and shapes. The outer contours of the chute 211 and the guide portion 311 are compatible. The guide portion 311 may be cylindrical and the chute 211 may be elongated. The ends of the chute 211 along the second direction may be arc-shaped to match the guide portion 311.

[0109] In one embodiment, along the width direction of the slideway 21 , the width dimension of the positioning hole 212 is greater than the width dimension of the slide groove 211 .

[0110] When the positioning hole 212 is a circular hole, the slide 21 includes a strip-shaped slide groove 211 and a positioning hole 212 whose diameter is greater than the width of the slide groove 211. The sizes of the guide portion 311 and the locking portion 312 of the locking member 31 are correspondingly distinguished. When the guide portion 311 and the locking portion 312 are both cylindrical structures, the diameter of the guide portion 311 is smaller than the diameter of the locking portion 312. The guide portion 311 can be called a small neck and the locking portion 312 can be called a large neck. The diameter of the guide portion 311 is slightly smaller than the width of the slide groove 211, so that the guide portion 311 can slide freely along the slide groove 211. The diameter of the locking portion 312 is slightly smaller than the diameter of the positioning hole 212, and the locking portion 312 can be accommodated in the diameter of the positioning hole 212.

[0111] In one embodiment, along the width direction of the slideway 21 , the width dimension of the locking portion 312 is greater than the width dimension of the guiding portion 311 .

[0112] In this manner, if the locking member 31 is not pressed in the first direction, the locking portion 312 can only be located within the positioning hole 212, rather than moving into the slide groove 211. At this point, the locking member 31 is temporarily fixed relative to the positioning hole 212, and the first support member 1 and the second support member 2 are also relatively fixed, forming a stable support function. When the locking member 31 is pressed in the first direction, the locking portion 312 is released from the positioning hole 212, and the guide portion 311 can slide from the positioning hole 212 into the slide groove 211, completing the unlocking process.

[0113] In one embodiment, Figure 7 As shown, the locking member 31 further includes a stopper 313 , which is disposed on at least one of the sides where the guide portion 311 and the locking portion 312 are away from each other.

[0114] With this arrangement, the stop portion 313 is arranged on the outside of the guide portion 311 or the locking portion 312. Since the locking member 31 needs to be pressed along the first direction, the stop portion 313 can be used to prevent the locking member 31 from falling out of the slide 21, thereby achieving the limitation of the guide portion 311 and / or the locking portion 312.

[0115] In one embodiment, along the width direction of the slideway 21 , the width dimension of the stopper 313 is greater than the width dimension of the positioning hole 212 .

[0116] In this manner, the stopper 313 is relatively wide and located outside the guide portion 311 or the locking portion 312. This provides the user with a larger pressing area, making it easier for the user to press and unlock the lock. Furthermore, the larger stopper 313 will not enter the positioning hole 212, making it easier for the user to press the stopper 313 again later.

[0117] It should be noted that if Figure 7 As shown, the locking member 31 can be composed of a screw and a T-nut. The T-nut has a large end and a small end. The threaded portion of the screw is threadedly connected to the small end of the T-nut. In this case, the threaded portion of the screw is the guide portion 311, and the small end of the T-nut is the locking portion 312. The large end of the T-nut and the nut of the screw are the stopper portion 313. Assembling the locking portion 312 in this manner has a simple structure and low production cost. During installation, the threaded portion of the screw can be first inserted into the positioning hole 212 and the fixing hole 11, and then the threaded portion of the screw can be threadedly connected to the small end of the T-nut, which has the advantage of easy installation.

[0118] It should be noted that if Figure 8-Figure 9 As shown, the locking member 31 can be composed of a sleeve and a rivet. One end of the rivet is a stepped shaft with a large shaft and a small shaft. The large shaft is connected to the shank of the rivet through the small shaft. The other end of the rivet is riveted to the sleeve. In this case, the shank of the rivet serves as a guide portion 311, the small shaft of the stepped shaft serves as a locking portion 312, and the large shaft and sleeve of the stepped shaft serve as stop portions 313. During installation, the shank of the rivet can be first inserted into the positioning hole 212 and the fixing hole 11, and then the rivet can be riveted to the sleeve. This simple structure is easy to install.

[0119] In one embodiment, Figure 7-Figure 9 As shown, the locking assembly 3 further includes a reset member 32 , which is sleeved on the outside of the locking member 31 and disposed between the first support member 1 and the stop portion 313 of the locking member 31 , and is elastic and used for resetting the locking member 31 .

[0120] When the support structure 200 needs to be raised, the stopper 313 of the locking portion 312 is pressed by external force. The reset member 32 can optionally be a spring. The spring compresses and pushes the locking portion 312 away from the positioning hole 212, so that the first support member 1 and the second support member 2 can slide relative to each other and extend, thereby raising the height of the support structure 200. When the support structure 200 needs to be lowered, the locking assembly 3 is pressed and unlocked. The first support member 1 and the second support member 2 can slide relative to each other and shorten. Since the compressed reset member 32 has an elastic force, under this elastic force, the locking portion 312 can enter the positioning hole 212, completing the self-locking process. In this way, the height adjustment operation is very simple, and the pressing direction of the reset member 32 also makes the user's operation more smooth, which is convenient for the user to operate.

[0121] Example 2

[0122] This embodiment is similar to the first embodiment, and the only difference lies in the detailed structures of the first support member 1 , the second support member 2 and the locking assembly 3 .

[0123] Specifically, if Figure 10-11 As shown, there are two fixing holes 11, which are arranged on both sides of the first support member 1. Compared with the first support member 1 of the first embodiment having a single-side hole structure, the first support member 1 provided in this embodiment has a double-side hole structure. Figure 12-13 As shown, there are two slideways 21, which are arranged on both sides of the second support member 2 along the axial direction of the locking assembly 3. Compared with the single-sided slideway structure of the second support member 2 in the first embodiment, the second support member 2 provided in this embodiment has a double-sided slideway structure.

[0124] Among them, such as Figure 14 As shown, the locking member 31 also includes a fixing portion 314 and a guide portion 315. One end of the guide portion 315 is connected to the locking portion 312, and the other end is connected to the fixing portion 314. The fixing portion 314 and the guide portion 315 are connected to each other and are coaxially arranged. The locking portion 312 and the fixing portion 314 can be respectively correspondingly penetrated into the two fixing holes 11, and the guide portion 311 and the guide portion 315 can respectively correspond to the two slideways 21 for sliding cooperation.

[0125] In this way, the guide portion 311 passes through the fixing hole 11 located on one side of the first support member 1, and the end of the guide portion 311 away from the locking portion 312 is extended in the reverse direction to form a guide portion 315, and the guide portion 315 passes through the fixing hole 11 located on the other side of the first support member 1. At this time, the locking assembly 3 can pass through the entire first support member 1 along the first direction, thereby improving the support balance and stability of the locking assembly 3.

[0126] In the unlocked state, the guide portion 311 and the guide portion 315 can be inserted into the two slideways 21 and slideably engage therewith, allowing the guide portion 311 and the guide portion 315 to be supported by both slideways 21, thereby improving the smoothness and balance of sliding. In the locked state, the locking portion 312 and the fixing portion 314 can be inserted into the two fixing holes 11, respectively, and the two fixing holes 11 respectively support the locking portion 312 and the fixing portion 314 to ensure stability at the height position.

[0127] In one embodiment, along the width direction of the slideway 21 , the width dimension of the fixing portion 314 is greater than the width dimension of the guide portion 315 , and the width dimension of the fixing portion 314 is greater than the width dimension of the slide groove 211 .

[0128] In this manner, if the locking member 31 is not pressed in the first direction, the fixing portion 314 can only be located within the positioning hole 212, rather than moving into the slide groove 211. At this point, the locking member 31 is temporarily fixed relative to the positioning hole 212, and the first support member 1 and the second support member 2 are also relatively fixed, forming a stable support function. When the locking member 31 is pressed in the first direction, the fixing portion 314 is disengaged from the positioning hole 212, and the guide portion 315 can slide from the positioning hole 212 into the slide groove 211, completing the unlocking process.

[0129] In one embodiment, the locking member 31 further includes a limiting portion 316 . The limiting portion 316 is disposed on a side of the fixing portion 314 away from the guiding portion 315 and is used to limit the fixing portion 314 .

[0130] With this arrangement, the limiting portion 316 is disposed outside the fixing portion 314 . The limiting portion 316 can prevent the locking member 31 from escaping from the slideway 21 , thereby limiting the fixing portion 314 .

[0131] In one embodiment, along the width direction of the slideway 21 , the width dimension of the limiting portion 316 is greater than the width dimension of the positioning hole 212 .

[0132] In this way, the width of the limit portion 316 is relatively large, which can prevent the fixing portion 314 from falling out of the slide 21, making it easier for the user to press and unlock. At the same time, the limit portion 316 with a larger width will not enter the positioning hole 212, making it easier for the user to press again later.

[0133] It is understandable that the fixing portion 314 and the locking portion 312 have similar shapes and sizes, so the shape and position relationship between the fixing portion 314 and the slide 21 can refer to the shape and position relationship between the locking portion 312 and the slide 21, so this embodiment will not be described in detail.

[0134] When the first support member 1 and the second support member 2 are both pipes with a circular cross-section, the outer wall of the pipe has an arc, which makes the contact area between the locking assembly 3 and the first support member 1 and the second support member 2 smaller, resulting in problems of shaking and poor support effect.

[0135] To this end, the first support member 1 is provided with a bearing boss 12 , and the fixing hole 11 passes through the bearing boss 12 along the axial direction of the locking assembly 3 .

[0136] For example, the bearing boss 12 is provided on the outer wall of the first support member 1, and the fixing hole 11 passes through the bearing boss 12. This increases the depth of the fixing hole 11, thereby increasing the contact area between the locking assembly 3 and the fixing hole 11, further improving support stability. Furthermore, when locked, this prevents excessive gaps from forming between the locking assembly and the first support member 1, thereby preventing users from being scratched by the edges due to the gap and improving safety.

[0137] Because the mating surface between the locking assembly 3 and the first support member 1 is flat, a gap exists between the locking assembly 3 and the outer wall of the first support member 1, preventing the locking assembly 3 from being tightly attached to the outer wall of the first support member 1. To this end, a mating end surface 121 is provided on the side of the bearing boss 12 away from the first support member 1, and the locking assembly 3 can abut against the mating end surface 121.

[0138] With this arrangement, the mating end face 121 provides a resting position for the locking assembly 3. When the user presses the locking assembly 3, the limiting portion 316 or the stopping portion 313 of the locking assembly 3 fits into the mating end face 121, avoiding noise or abnormal sound caused by the gap, and also serving as a reminder of the position to a certain extent.

[0139] For example, the bearing boss 12 may be a planar circular iron sheet welded to the outer wall of the first support member 1 .
