[0002] A monitor stand is a support device that can support and place various products (such as monitors, laptops, or tablets) to ensure that the viewing height of the products meets the user's needs.

[0003] In related technologies, existing support devices are easily subjected to external forces (such as external vibrations), which can cause the tabletop to tilt relative to the table legs, resulting in insufficient support strength of the support and affecting the user experience. Utility Model Content

[0004] This application provides a support device and a height-adjustable table to solve the technical problem that existing support devices are easily subjected to external forces, causing the tabletop to tilt relative to the table legs, resulting in insufficient support strength of the support and affecting the user experience.

[0005] In a first aspect, this application provides a support device, including: a first support member having a receiving cavity, the first support member being used to place a support member;

[0006] The second support member is movably mounted on the first support member;

[0007] A locking assembly is disposed within the receiving cavity. The locking assembly includes a push plate and a locking strip. The push plate is movably disposed on the first support member. The locking strip includes a first end and a second end disposed opposite to each other. The first end of the locking strip is drivenly connected to the push plate, and the second end of the locking strip is detachably connected to the second support member.

[0008] Specifically, when the push plate is subjected to force and moves relative to the first support member in the first direction, the second end of the locking bar can move away from the second support member in the second direction, so that the second support member has a first state of being movable relative to the first support member; or, when the push plate is subjected to force and moves relative to the first support member in the opposite direction of the first direction, the second end of the locking bar can move closer to the second support member in the opposite direction of the second direction, so that the second support member has a second state of being fixed relative to the first support member, wherein the first direction and the second direction intersect.

[0009] In one possible implementation, the first support member includes a support frame and a cover plate, the support frame and the cover plate being disposed opposite to each other and forming an accommodating cavity between them; the push plate is slidably connected to the cover plate so that the push plate can slide in a first direction; the locking strip is slidably connected to the support frame so that the locking strip can slide in a second direction.

[0010] In one possible implementation, a first slide groove is provided on the side of the push plate away from the cover plate. The first slide groove has an inclined section that is inclined relative to a first direction. A protrusion is provided at the first end of the locking bar, and the protrusion is slidably connected to the first slide groove.

[0011] In one possible implementation, the second support member is provided with a plurality of first slots, and the second end of the locking strip is connected to one of the first slots.

[0012] In one possible implementation, a first through groove is provided on the support frame, and the second support member includes a connected support portion and a sliding portion. The sliding portion is used to slide with the support frame. The end of the sliding portion away from the support portion passes through the first through groove and extends into the receiving cavity. A first slot is provided on the sliding portion so that the first support member and the sliding portion have a first state or a second state.

[0013] In one possible implementation, a second slide groove is provided on the sliding part, the length direction of the second slide groove is parallel to the first direction, a guide post is provided on the first support member, the guide post is slidably connected to the second slide groove, the first end of the guide post is connected to the support frame, and the second end of the guide post is connected to the cover plate.

[0014] In one possible implementation, the first support member includes a baffle disposed within the accommodating cavity and fixedly connected to the support frame. The baffle is provided with a third sliding groove, the length direction of which is parallel to the second direction. A locking strip is slidably connected to the third sliding groove to limit the displacement of the locking strip in the second direction.

[0015] In one possible implementation, the support device includes a retaining ring, the first end of which is connected to a baffle, and the second end of which is provided with a cantilever portion that is suspended relative to the baffle and is connected to one of the first retaining slots.

[0016] In one possible implementation, the push plate is provided with an ear, the ear is provided with a first protrusion, the cover plate is provided with a first reinforcing rib on the side facing the receiving cavity, the first reinforcing rib is provided with two first grooves, and the first protrusion is engaged with one of the first grooves.

[0017] Alternatively, a second reinforcing rib is provided on the side of the cover plate facing the receiving cavity, and a second protrusion is provided on the second reinforcing rib. Two second grooves are provided on the ear, and the second protrusion is engaged with one of the second grooves.

[0018] Secondly, this application also provides a height-adjustable desk, including a tabletop and a support device as described above, wherein a first support member of the support device is connected to the tabletop.

[0019] The technical solutions provided in this application have the following advantages compared with the prior art:

[0020] The bracket device provided in this application embodiment, when a vertically upward external force is applied to the push plate, the push plate moves upward relative to the first support member. Under the linkage of the push plate and the locking strip, the second end of the locking strip can move away from the second support member along the second direction, causing the locking strip to separate from the second support member. The second support member reaches the first state. At this time, the user can apply an external force to the second support member, causing the second support member to move up and down relative to the first support member, thereby adjusting the height of the first support member. When a vertically downward external force is applied to the push plate, the push plate moves downward relative to the first support member. Under the linkage of the push plate and the locking strip, the second end of the locking strip can move closer to the second support member along the opposite direction of the second direction until the locking strip connects with the second support member. At this time, the second support member reaches the second state. Since the first direction and the second direction intersect, the push plate will provide locking forces in the first and second directions to the locking strip, so that the locking strip remains connected to the second support member. The second support member is in a locked state, and the second support member cannot move up and down relative to the first support member. The height of the first support member remains unchanged. Compared to existing technologies, this technology can improve the overall structural strength and support strength of the bracket. The second support component is always under locking force and remains stable in the locked state. The second support component is not easy to tilt relative to the first support component, and the adjustment process is smooth and without jamming, thereby optimizing the user experience.

[0021] The height-adjustable table provided in this application includes the aforementioned support device. The second support member, in its locked state, is always subjected to a locking force and remains stable, making it difficult for the second support member to tilt relative to the first support member. Therefore, it naturally possesses the technical effects of the aforementioned support device. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0044] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0045] To address the technical problem that existing support devices are prone to tilting relative to the table legs due to external forces, resulting in insufficient support strength and affecting user experience, this application provides a support device and a height-adjustable table that can improve the overall structural strength and support strength of the support. The second support member is always subjected to locking force in the locked state to maintain a stable state, and the adjustment process is smooth and without jamming, thereby optimizing the user experience.

[0046] Figure 1 and Figure 2 A support device 1 provided in this application embodiment includes a first support member 11, a second support member 12, and a locking assembly 13. The first support member 11 is provided with a receiving cavity 111 and is used to support or place a product to be supported (such as a monitor, laptop, or tablet computer). The second support member 12 is movably disposed on the first support member 11. The locking assembly 13 is disposed in the receiving cavity 111 and includes a push plate 131 and a locking strip 132. The push plate 131 is movably disposed on the first support member 11, and the locking strip 132 includes a first end and a second end disposed opposite to each other. The first end of the locking strip 132 is driven by the push plate 131. The locking bar 132 is detachably connected to the second support member 12. When the push plate 131 is subjected to force and moves relative to the first support member 11 in a first direction, the second end of the locking bar 132 can move away from the second support member 12 in a second direction, so that the second support member 12 has a first state of being movable relative to the first support member 11. Alternatively, when the push plate 131 is subjected to force and moves relative to the first support member 11 in the opposite direction of the first direction, the second end of the locking bar 132 can move closer to the second support member 12 in the opposite direction of the second direction, so that the second support member 12 has a second state of being fixed relative to the first support member 11, wherein the first direction and the second direction intersect.

[0047] For ease of explanation and understanding, the first direction can be the Z-direction shown in the figure. For example, the first direction is the height direction of the first support member, i.e., vertically upward or vertically downward. The second direction can be the X-direction shown in the figure, intersecting with the first direction. For example, the second direction is the length direction of the first support member. The first support member may include a first support surface, which may be disposed on the side of the first support member 12 away from the second support member 11. The first support surface is used to support or place the component to be supported. The side of the second support member 12 away from the first support member 11 may be provided with a second support surface. When using the bracket device 1, the second support surface of the second support member 12 is placed on the ground, and the first support surface of the first support member 11 can support or place the component to be supported. Understandably, when an upward vertical force is applied to the push plate 131, the push plate 131 moves upward relative to the first support member 11. Under the linkage of the push plate 131 and the locking strip 132, the second end of the locking strip 132 can move away from the second support member 12 along the second direction X, so that the locking strip 132 separates from the second support member 12, and the second support member 12 reaches the first state. At this time, the user can apply an external force to the second support member 12, so that the second support member 12 moves up and down relative to the first support member 11, thereby adjusting the height of the first support surface of the first support member 11 relative to the second support surface of the second support member 12. When a vertically downward external force is applied to the push plate 131, the push plate 131 moves downward relative to the first support member 11. Under the linkage of the push plate 131 and the locking strip 132, the second end of the locking strip 132 can approach the second support member 12 in the opposite direction of the second direction until the locking strip 132 connects with the second support member 12. At this time, the second support member 12 reaches the second state. Since the first direction and the second direction intersect, the push plate 131 will provide locking forces in the first and second directions to the locking strip 132, so that the locking strip 132 remains connected to the second support member 12. The second support member 12 is in the locked state and cannot move up or down relative to the first support member 11. The height of the first support surface of the first support member 11 relative to the second support surface remains unchanged. Compared with the prior art, this bracket device 1 can improve the overall structural strength and support strength of the bracket. The second support member 12 is always subjected to locking force and remains stable in the locked state. The first support member 11 is not easy to tilt. The adjustment process is smooth and does not jam, thereby optimizing the user experience.

[0048] Optionally, the first support member 11 can be configured as an integral structure or as a separate structure.

[0049] In one embodiment, such as Figure 2As shown, the first support member 11 includes a support frame 112 and a cover plate 113. The support frame 112 and the cover plate 113 are arranged opposite to each other, and a receiving cavity 111 is formed between them. A push plate 131 is slidably connected to the cover plate 113 so that the push plate 131 can slide in a first direction. A locking strip 132 is slidably connected to the support frame 112 so that the locking strip 132 can slide in a second direction. Specifically, a fourth sliding groove may be provided on the support frame 112, and the locking strip 132 is slidably connected to the fourth sliding groove. Further, the support frame 112 has a first opening, and the cover plate 113 covers the first opening of the support frame 112. With this arrangement, a receiving cavity 111 can be formed between the cover plate 113 and the support frame 112. By placing the locking assembly 13 in the receiving cavity 111, the locking assembly 13 can be hidden in the receiving cavity 111 between the fixed parts, thereby improving the overall aesthetics of the bracket device 1. Understandably, when an upward vertical force is applied to the push plate 131, the push plate 131 moves upward relative to the cover plate 113. Under the linkage of the push plate 131 and the locking strip 132, the locking strip 132 can move relative to the support frame 112 in the second direction until the second end of the locking strip 132 separates from the second support member 12, and the second support member 12 reaches the first state. At this time, the user can apply an external force to the second support member 12, so that the second support member 12 moves up and down relative to the first support member 11, thereby adjusting the height of the first support surface of the first support member 11 relative to the second support surface. When a vertically downward external force is applied to the push plate 131, the push plate 131 moves downward relative to the cover plate 113. Under the linkage of the push plate 131 and the locking strip 132, the locking strip 132 can move relative to the support frame 112 in the opposite direction of the second direction until the second end of the locking strip 132 is connected to the second support member 12. At this time, the second support member 12 reaches the second state. Since the first direction and the second direction intersect, the push plate 131 will provide locking force in the first direction and the second direction to the locking strip 132, so that the locking strip 132 remains connected to the second support member 12. The second support member 12 is in a locked state and cannot move up and down relative to the first support member 11. The height of the first support surface of the first support member 11 relative to the second support surface remains unchanged.

[0050] The connection between the support frame 112 and the cover plate 113 can be at least one of the following: snap-fit ​​connection or fastener connection. For example, the support frame 112 may have an annular groove at the edge of the first opening, which fits the edge of the cover plate 113; the inner sidewall of the support frame 112 may have a snap-fit, and the outer periphery of the cover plate 113 may have a second slot for snap-fit ​​connection with the snap-fit; multiple studs may be provided on the side of the support frame 112 facing the cover plate 113, and multiple connecting holes may be provided on the cover plate 113, with each connecting hole corresponding to a stud, and one end of a screw threadedly connected to the stud through the connecting hole. This configuration allows for a detachable connection between the support frame 112 and the cover plate 113. Of course, in some other embodiments, the support frame 112 and the cover plate 113 may also be connected by welding.

[0051] In one embodiment, such as Figures 3 to 5 As shown, the push plate 131 has a first slide groove 1311 on the side opposite to the cover plate 113. The first slide groove 1311 includes an inclined section, which is inclined relative to a first direction. The first end of the locking bar 132 has a protrusion 1321, which is slidably connected to the first slide groove 1311. Specifically, the protrusion 1321 and the locking bar 132 can be detachably connected, or they can be an integral structure.

[0052] Understandably, when an upward vertical force is applied to the push plate 131, the push plate 131 moves upward relative to the cover plate 113 in the first direction. Since the inclined section of the first slide groove 1311 is inclined relative to the first direction, the push plate 131 will apply a pressing force F1 perpendicular to the inclined section of the first slide groove 1311 to the protrusion 1321. The pressing force has a component force F2 in the second direction. The protrusion 1321 is slidably connected to the first slide groove 1311. Therefore, the locking bar 132 moves relative to the support frame 112 in the second direction under the action of the component force F2 until the second end of the locking bar 132 separates from the second support member 12. The second support member 12 reaches the first state. At this time, the user can apply an external force to the second support member 12 to make the second support member 12 move up and down relative to the first support member 11, thereby adjusting the height of the first support member 11. When a vertically downward external force is applied to the push plate 131, the push plate 131 moves upward relative to the cover plate 113 in the first direction. Similarly, the push plate 131 will apply a pressing force to the protrusion 1321 perpendicular to the inclined section of the first slide groove 1311. Under the action of the component force of the pressing force in the second direction, the locking strip 132 can move relative to the support frame 112 in the opposite direction of the second direction until the second end of the locking strip 132 is connected to the second support member 12. At this time, the second support member 12 reaches the second state. Since the first direction and the second direction intersect, the push plate 131 will provide locking forces in the first direction and the second direction to the protrusion 1321 of the locking strip 132 at the same time, so that there will be no relative sliding between the first support member 11 and the second support member 12.

[0053] The second support member 12 is provided with a plurality of first slots 1221, and the second end of the locking strip 132 is connected to one of the first slots 1221. In the second state, the second end of the locking strip 132 is always engaged with the first slot 1221 of the second support member 12, so that the second support member 12 is in a locked state, and the second support member 12 cannot move up and down relative to the first support member 11, and the height of the first support surface of the first support member 11 relative to the second support surface remains unchanged.

[0054] It should be noted that when the second support member 12 reaches the first state, the user can easily move the second support member 12 up and down relative to the first support member 11, thereby adjusting the height of the top of the first support member 11 relative to the support surface. During the adjustment of the top height of the bracket, the user does not need to apply force to the push plate 131, greatly facilitating user operation and optimizing the user experience. The distance between two adjacent first slots 1221 is the first stroke. If the distance the second support member 12 moves relative to the first support member 11 in the second direction is the first stroke, the user can push the push plate 131, causing the second end of the locking strip 132 to engage with the first slot 1221 of the second support member 12, switching the second support member 12 from the first state to the second state.

[0055] Optionally, the first end of the locking bar 132 is provided with a first clearance portion to prevent the locking bar 132 from interfering with the push plate 131 during the reciprocating movement in the second direction.

[0056] In some embodiments, such as Figure 2As shown, the support frame 112 is provided with a first through groove 1121. The second support member 12 includes a connected support portion 121 and a sliding portion 122. The support portion 121 can increase the contact area of ​​the second support member 12 on the second support surface, thereby improving the support stability of the second support member 12 on the second support surface. The sliding portion 122 is used to slide with the support frame 112. One end of the sliding portion 122 away from the support portion 121 passes through the first through groove 1121 and extends into the receiving cavity 111. The sliding portion 122 is provided with a first slot 1221. Specifically, in a preferred embodiment, the support portion 121 is flat, and the sliding portion 122 is flat. Two sliding portions 122 can be provided, with the two sliding portions 122 respectively provided at both ends of the support portion 121. Two first through grooves 1121 are provided accordingly. The first through grooves 1121 are provided at the bottom of the support frame 112, and the two sliding portions 122 correspond one-to-one with the first through grooves 1121 and are slidably connected. Accordingly, two locking strips 132 are provided, and two first sliding grooves 1311 are provided on the side of the push plate 131 away from the cover plate 113. The two locking strips 132 correspond one-to-one with the first sliding grooves 1311. With this configuration, when it is necessary to lock the second support member 12, the two locking strips 132 are respectively engaged with the first slots 1221 of the sliding part 122, which can improve the uniformity of force on the second support member 12, prevent the second support member 12 from tilting due to external force vibration in the locked state, and improve the overall reliability of the structure. It is not easily damaged under normal drop conditions and has a strong load-bearing capacity. When it is necessary to adjust the height of the first support surface of the first support member 11 relative to the second support surface, two locking strips are provided, which can improve the smoothness of the sliding of the second support member 12 relative to the support frame 112. The end of the sliding part 122 away from the support part 121 extends through the first through groove 1121 and into the receiving cavity 111. When the second support member 12 is in the first state, the user pulls the support part 121, which allows the support part 121 to slide along the first direction on the first through groove 1121, thereby adjusting the height of the top of the first support member 11 relative to the support surface.

[0057] Of course, in another embodiment, a sliding part 122 may also be provided. The sliding part 122 may be provided at the end of the support part 121 or in the middle of the support part 121. The specific working principle and beneficial effects can be referred to the above embodiments, and will not be repeated here.

[0058] It is worth mentioning that when the height of the first support surface of the first support member 11 relative to the second support surface is at its minimum, there is a gap between the support part 121 and the support frame 112, which allows the user's hand to pass through the gap. The support part 121 or the support frame 112 applies external force to make the second support member 12 slide relative to the first support member 11.

[0059] In one embodiment, such as Figure 2 and Figure 4 As shown, a second sliding groove 1222 is provided on the sliding part 122, and the length direction of the second sliding groove 1222 is parallel to the first direction. A guide post 114 is provided on the first support member 11, and the guide post 114 is slidably connected to the second sliding groove 1222. The first end of the guide post 114 is connected to the support frame 112, and the second end of the guide post 114 is connected to the cover plate 113. By providing the guide post 114, the guide post 114 and the second sliding groove 1222 are slidably adapted. The guide post 114 plays a guiding role in the sliding process of the second support member 12. When the second support member 12 is in the first state, the user pulls the support part 121, which can make the support part 121 slide in the first direction, thereby adjusting the height of the first support surface of the first support member 11 relative to the second support surface.

[0060] In one embodiment, such as Figure 6 As shown, the fixed bracket 11 may include a baffle 115, which is disposed within the receiving cavity 111 and fixedly connected to the support frame 112. A third sliding groove 1151 is provided on the baffle 115, with its length direction parallel to the second direction. A locking strip 132 is slidably connected to the third sliding groove 1151 to limit the displacement of the locking strip in the second direction. Optionally, the baffle 115 and the support frame 112 can be fixedly connected by welding, or they can be detachably connected. Specifically, the support frame 112 has multiple threaded holes, and the baffle 115 has multiple through holes, each corresponding to a threaded hole. One end of a screw passes through one of the through holes and is threadedly connected to a threaded hole. The third groove 1151 limits the displacement of the locking bar 132 in the second direction, so that the locking bar 132 can only slide in the second direction under the squeezing force applied by the push plate 131, thereby realizing the switching of the second support member 12 between the first state and the second state.

[0061] Optionally, a second clearance part is provided on the baffle 115 so that the push plate 131 interferes with the baffle 115 during the reciprocating movement in the first direction.

[0062] In one embodiment, such as Figure 6As shown, the support device 1 may include a retaining spring 14. The first end of the retaining spring 14 is connected to the baffle 115, and the second end of the retaining spring 14 is provided with a cantilever portion 141. The cantilever portion 141 is suspended relative to the baffle 115 and is connected to one of the first slots 1221. Specifically, the first end of the retaining spring 14 is bent to form a connecting piece, which can be fixedly connected to the baffle 115 by fasteners such as screws. The cantilever portion 141 may be provided with a protrusion, which engages with one of the first slots 1221 of the sliding portion 122. The cantilever 141 is suspended relative to the baffle 115, thus possessing a certain degree of elasticity. In its natural state, the protrusion of the cantilever 141 engages with one of the first slots 1221 of the sliding part 122. When the second support member 12 is in the first state, and the sliding part 122 of the second support member 12 moves relative to the first support member 11, the cantilever 141 is disengaged from the first slot 1221 by force. If the distance the second support member 12 moves relative to the first support member 11 in the second direction is the first stroke, then the cantilever 141... The arm 141 engages with the adjacent first slot 1221 under its own elastic restoring force, thereby providing force feedback to the user. For example, the user can hear a crisp "click" sound, indicating that the second support 12 has moved a first stroke relative to the first support 11. The user can push the push plate 131 so that the second end of the locking strip 132 engages with the adjacent first slot 1221, and the second support 12 switches from the first state to the second state, realizing multi-level adjustment of the height of the first support 11.

[0063] In one embodiment, such as Figure 3 , Figure 7 and Figure 8As shown, the push plate 131 is provided with an ear 1312. The end of the ear 1312 away from the push plate 131 extends towards the cover plate 113. The ear 1312 is provided with a first protrusion 1313. The cover plate 113 is provided with a first reinforcing rib 1131 on the side facing the receiving cavity 111. The first reinforcing rib 1131 is provided with two first grooves 1132. The first protrusion 1313 is engaged with one of the first grooves 1132. By setting two first grooves 1132, when a vertically upward external force is applied to the push plate 131, the push plate 131 moves upward relative to the first support member 11. Under the linkage of the push plate 131 and the locking strip 132, the second end of the locking strip 132 can move away from the second support member 12 in the second direction, so that the locking strip 132 separates from the second support member 12, and the second support member 12 reaches the first state. At this time, the first protrusion 1313 can be engaged with the first groove 1132 located above, thereby providing feedback force to the user and providing a better user experience. When a vertically downward external force is applied to the push plate 131, the push plate 131 moves downward relative to the first support member 11. Under the linkage of the push plate 131 and the locking strip 132, the second end of the locking strip 132 can approach the second support member 12 in the opposite direction of the second direction until the locking strip 132 is connected to the second support member 12. At this time, the second support member 12 reaches the second state. At this time, the first protrusion 1313 can be engaged with the first groove 1132 located below, which can also provide feedback force to the user and optimize the user experience.

[0064] In another embodiment (not shown in the figure), a second reinforcing rib is provided on the side of the cover plate 113 facing the receiving cavity 111, and a second protrusion is provided on the second reinforcing rib. Two second grooves are provided on the ear portion 1312, and the second protrusion is engaged with one of the second grooves. In this embodiment, the working principle is the same as in the above embodiment, and it can also provide feedback to the user on the force of the second support member 12 being in the active state and the force of the second support member 12 being in the locked state. Further details are omitted here.

[0065] In some embodiments, such as Figure 2 As shown, an operating part 1314 is provided on the side of the push plate 131 away from the receiving cavity 111. A second through groove 1133 is provided on the cover plate 113. The length direction of the second through groove 1133 is parallel to the first direction. The end of the operating part 1314 away from the push plate 131 extends along the direction away from the receiving cavity 111 and passes through the second through groove 1133. The user can easily apply force to the operating part 1314 of the push plate 131. The operating part 1314 slides along the second through groove 1133. The second through groove 1133 restricts the displacement of the push plate 131 in the second direction, so that the push plate 131 reciprocates in the first direction. The second support member 12 is detachably connected to the locking strip 132, thereby realizing the switching between the first state and the second state of the second support member 12.

[0066] It should be noted that this application does not impose specific limitations on the shape and size of the operation part 1314. For example, the operation part 1314 can be configured as a columnar button or a sheet-shaped button.

[0067] In one embodiment, such as Figure 4 As shown, an anti-slip pad 1211 is provided on the side of the support part 121 away from the first support member 11. The anti-slip pad 1211 can be made of rubber material. When the bottom of the support part 121 is placed on the support surface, the anti-slip pad 1211 can increase the friction between it and the support surface, thus playing an anti-slip role.

[0068] like Figure 9 As shown, a height-adjustable table 100 includes a tabletop 2 and a support device 1 as previously shown. The first support member 11 of the support device 1 is fixedly connected to the tabletop 2. At least two support devices 1 are provided, with the two support devices 1 respectively disposed on both sides of the tabletop 2 to improve the support stability of the tabletop 2. Specifically, the first support surface of the first support member 11 can be fixedly connected to the tabletop 2, and the side of the tabletop away from the first support member can be used to place the item to be supported.

[0069] The second support member 12 remains stable under a locking force when locked, and it is not easy for the second support member 12 to tilt relative to the first support member 11. That is, the tabletop 2 is not easy to tilt, and it can stably support the product placed on the tabletop 2. Therefore, it naturally has the technical effects of the aforementioned bracket device 1.

[0070] In one embodiment, the height-adjustable desk 100 includes a power supply module disposed within a receiving cavity 111. An interface 116 is provided on the first support member 11, including but not limited to a PD charging interface, a TYPE-C interface, a TF / SD memory card interface, an HDMI interface, and a USB interface. A first end of a cable is connected to the power supply module through the receiving cavity 111 within the first support member 11, and a second end of the cable is connected to a monitor, laptop, or tablet computer through a connector terminal to achieve charging or data exchange functions. Alternatively, the interface 116 can also be provided on the desk panel 2.

[0071] Multiple interfaces 116 can be configured, and these interfaces 116 can be arranged at intervals. Multiple interfaces 116 of the same type can be arranged adjacently or staggered. This application does not impose specific restrictions in this regard.
