Description

[Technical Field]

[0001] This invention relates to the field of height-adjustable desks, and more particularly to height-adjustable desks that are easy to install. [Background Technology]

[0002] A table is an essential piece of furniture, typically consisting of a frame and legs. With societal development, the popularity of height-adjustable desks has increased. These desks have numerous mechanical mechanisms, such as uprights that drive the frame's height adjustment. The frame comprises a tabletop and a supporting frame, which maintains the tabletop's stability during height adjustment. The supporting frame is a metal structure consisting of crossbeams and side panels. Currently, the crossbeams and side panels are generally attached to the tabletop with screws. However, this requires a large number of screws, and if even a few screws become misaligned during installation, it can cause misalignment of the frame and even the uprights. Furthermore, the large number of screws makes disassembly and reassembly difficult and inconvenient for users. [Summary of the Invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and propose a height-adjustable table that is easy to install, thus solving the problem that the height-adjustable table is difficult to disassemble and assemble and is inconvenient for users.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An easy-to-install height-adjustable desk includes a tabletop, a height-adjustable column, a crossbeam assembly, and side panels located at both ends of the crossbeam assembly. The height-adjustable column, the crossbeam assembly, and the side panels are detachably mounted on the tabletop. One of the tabletop and the crossbeam assembly has a first positioning hole, and the other has a first positioning post that inserts into the first positioning hole. After the first positioning post slides relative to it, the first positioning hole positions the first positioning post in the height direction of the height-adjustable desk. One of the tabletop and the side panels has a second positioning hole, and the other has a second positioning post that inserts into the second positioning hole. After the second positioning post slides relative to it, the second positioning hole positions the second positioning post in the height direction of the height-adjustable desk. The height-adjustable column is connected to the crossbeam assembly and the side panels to restrict their sliding relative to the tabletop.

[0006] Based on the above scheme, the lifting column is provided with a first connector, and the crossbeam assembly and the side plate are provided with a second connector that can be plugged into and cooperate with the first connector to position the lifting column in the horizontal direction of the lifting table.

[0007] Based on the above scheme, the lifting column is also provided with a third connecting member, and the crossbeam assembly and / or the side plate are provided with a fourth connecting member that can cooperate with the third connecting member to position the lifting column in the height direction of the lifting table.

[0008] Based on the above scheme, one of the third connector and the fourth connector is an elastic latch that can extend and retract in the horizontal direction of the lifting table or flip in the height direction of the lifting table, and the other is a lock hole that is inserted into the elastic latch.

[0009] Based on the above scheme, one of the first connector and the second connector is a lock hole and the other is an elastic locking tongue. The elastic locking tongue is inserted into and locked into the lock hole to position the lifting column in the height direction of the lifting table.

[0010] Based on the above scheme, the lifting column is provided with a first through hole, and the crossbeam assembly and / or the side plate is provided with a second through hole. The lifting column is limited in the height direction of the lifting table by a pin passing through the first through hole and the second through hole.

[0011] Based on the above solution, at least one of the first connector and the second connector is provided with a guide surface that deviates from the height direction of the lifting table. The guide surface is pressed when the first connector and the second connector are inserted and engaged to drive the crossbeam assembly and the side plate closer to each other.

[0012] Based on the above scheme, the crossbeam assembly is also provided with a controller and a first power interface electrically connected to the controller, and the lifting column is provided with a second power interface. The first power interface cooperates with the second power interface during the process of the lifting column connecting to the crossbeam assembly.

[0013] Based on the above scheme, the crossbeam assembly is also provided with a cover plate, and the first power interface is installed on the cover plate.

[0014] Based on the above scheme, there are two lifting columns located at both ends of the crossbeam assembly. The crossbeam assembly is also equipped with a motor and a transmission mechanism connected to the motor. The transmission mechanism is in transmission cooperation with the two lifting columns.

[0015] Based on the above scheme, there are two lifting columns located at both ends of the crossbeam assembly, and a column crossbeam is provided between the two lifting columns. The column crossbeam is equipped with a controller that is electrically connected to the two lifting columns.

[0016] Based on the above scheme, the crossbeam assembly and the side plate are spliced ​​together to form a socket for the insertion of the lifting column. The lifting column cooperates with the side wall of the socket to position the crossbeam assembly and the side plate in the horizontal direction of the lifting table.

[0017] Based on the above scheme, one of the side plate and the crossbeam assembly has an opening, and the other is inserted into the opening to form the socket; or, one of the side plate and the crossbeam assembly has a first notch, and the other has a second notch at one end inserted into the first notch, and the first notch and the second notch form the socket.

[0018] Based on the above scheme, the side plate is provided with a first notch, the crossbeam assembly includes a first crossbeam and a second crossbeam slidably installed at both ends of the first crossbeam, the end of the second crossbeam is provided with a second notch, the side plate slides relative to the tabletop in a first direction, the second crossbeam slides relative to the tabletop in a second direction perpendicular to the first direction to insert into the first notch, the first notch and the second notch form a socket for the lifting column to be inserted, the inner walls of the first notch and the second notch are provided with a first guide block, the lifting column is provided with a second guide block that is inserted and cooperates with the first guide block, the inner wall of the second notch is also provided with an elastic locking tongue, and the side wall of the lifting column is provided with a lock hole that cooperates with the elastic locking tongue.

[0019] Based on the above scheme, the crossbeam assembly slides along a first direction to make the first mounting hole engage with the first positioning post, and the side plate at at least one end of the crossbeam assembly slides along a second direction deviating from the first direction to make the second mounting hole engage with the second positioning post.

[0020] Based on the above scheme, the crossbeam assembly includes a first crossbeam and a second crossbeam slidably mounted on both ends of the first crossbeam. The side plate slides in a direction that deviates from the second crossbeam and extends relative to the first crossbeam, so that the second mounting hole engages with the second positioning post.

[0021] Based on the above scheme, the first positioning hole includes a first insertion end and a first positioning end, the first positioning post includes a first small diameter section and a first large diameter section, the size of the first large diameter section is larger than the size of the first positioning end, the first positioning post is inserted from the first insertion end and passes through the first positioning hole, and the first small diameter section slides from the first insertion end to the first positioning end to axially limit the first positioning post.

[0022] Based on the above scheme, the second positioning hole includes a second insertion end and a second positioning end, and the second positioning post includes a second small diameter section and a second large diameter section. The size of the second large diameter section is larger than the size of the second positioning end. The second positioning post is inserted from the second insertion end and passes through the second positioning hole. The second small diameter section slides from the second insertion end to the second positioning end to axially limit the second positioning post.

[0023] The beneficial effects of this invention are:

[0024] This invention discloses a height-adjustable desk. A crossbeam assembly and side panels on the desk support the desk, increasing its strength and preventing bending. A lifting column allows the desk to be raised and lowered to adjust its height. The crossbeam assembly and side panels are mounted on the desk through engagement with a first positioning hole and a first positioning post, and a second positioning hole and a second positioning post. After engagement, the crossbeam assembly and side panels can be suspended from the desk. Furthermore, the first and second positioning posts are concealed by the crossbeam assembly and side panels, making them difficult for the user to observe.

[0025] When assembling the crossbeam assembly onto the tabletop, first align the first positioning pin with the first positioning hole and insert it into the first positioning hole. Then, slide the crossbeam assembly relative to the tabletop so that the first positioning hole can position the first positioning pin, thereby preventing the crossbeam assembly from moving in the height direction of the lifting table. When disassembling, simply slide the crossbeam assembly in the opposite direction to release the positioning of the first positioning pin by the first positioning hole.

[0026] The side panels and tabletop are fitted in the same way as the crossbeam assembly and tabletop. After both the side panels and crossbeam assembly are assembled onto the tabletop, the crossbeam assembly and side panels are connected by a lifting column, locking them together. The crossbeam assembly and side panels are connected as a single unit, preventing relative movement and maintaining their current position. This secures the crossbeam assembly, side panels, and tabletop together. The crossbeam assembly and side panels can be installed on the tabletop without screws, making assembly and disassembly convenient for users. The lifting column connects the crossbeam assembly and side panels for positioning, eliminating the need for additional locking mechanisms. Furthermore, the lifting column is also fixed to the tabletop, further reducing the assembly steps of the height-adjustable table. The first positioning hole, first positioning post, second positioning hole, and second positioning post are pre-installed on the height-adjustable table at the factory, eliminating the need for additional installation of the first and second positioning posts, thus reducing user installation work. This also improves the positional accuracy of the crossbeam assembly and side panels on the tabletop, ensuring optimal support performance.

[0027] Furthermore, the lifting column is provided with a first connecting member, and the crossbeam assembly and the side plate are provided with a second connecting member that can be inserted and engaged with the first connecting member to position the lifting column in the horizontal direction of the lifting table. After the first connecting member and the second connecting member are engaged, the lifting column cannot move in the horizontal direction of the lifting table, that is, the crossbeam assembly and the side plate are locked by the lifting column and cannot slide relative to the table.

[0028] Furthermore, the lifting column is also provided with a third connecting member, and the crossbeam assembly and / or the side plate are provided with a fourth connecting member that can cooperate with the third connecting member to position the lifting column in the height direction of the lifting table. Through the cooperation of the first and second connecting members, the crossbeam assembly and the side plate are fixed to the table by the lifting column. The cooperation of the fourth and third connecting members can limit the lifting column, preventing it from moving relative to the table in the height direction of the lifting table. The lifting column is held in the position that maintains the cooperation of the first and second connecting members, thus keeping the structure of the lifting table stable. Since the crossbeam assembly and the side plate are already fixed by the lifting column, the fourth connecting member on either of them can position the lifting column. If the fourth connecting member is provided on both the crossbeam assembly and the side plate, the stability of the cooperation between the lifting column, the crossbeam assembly, and the side plate can be further improved.

[0029] Furthermore, one of the third and fourth connecting members is a resilient latch that can extend and retract horizontally or flip vertically in the lifting table direction, and the other is a lock hole that engages with the resilient latch. The resilient latch and the lock hole only need to be inserted; no locking mechanism is required within the lock hole. If the resilient latch is extendable, the lifting column can be pushed to deform during assembly until the lock hole aligns with the resilient latch, after which the resilient latch can return to its original position and engage with the lock hole. If the resilient latch is flippable, the lifting column can be pushed to flip the resilient latch during assembly and insert it into the lock hole. The user can operate the resilient latch to return it to its original position to disassemble the lifting column.

[0030] Furthermore, one of the first connector and the second connector is a lock hole, and the other is a resilient locking tongue. The resilient locking tongue is inserted into and locked into the lock hole to position the lifting column in the height direction of the lifting table. After being inserted into the lock hole, the resilient locking tongue is locked in the lock hole, thereby fixing the lifting column. In this way, the first connector and the second connector, when engaged, can position the lifting column not only in the horizontal direction of the lifting table but also in the height direction of the lifting table, thus eliminating the need for an additional structure for positioning the lifting column in the height direction of the lifting table.

[0031] Furthermore, the lifting column is provided with a first through hole, and the crossbeam assembly and / or the side plate is provided with a second through hole. A pin passing through the first and second through holes limits the lifting column in the height direction of the lifting table. The crossbeam assembly and the side plate are positioned on the table. When the pin passes through the first and second through holes, the pin can limit the displacement of the lifting column in the radial direction of the pin. Since the crossbeam assembly and the side plate are already fixed by the lifting column, providing a second through hole on either of them can position the lifting column after the pin is installed. If second through holes are provided on both the crossbeam assembly and the side plate, the fit stability between the lifting column, the crossbeam assembly, and the side plate can be further improved.

[0032] Furthermore, at least one of the first and second connectors is provided with a guide surface offset from the height direction of the lifting table. This guide surface is pressed during the insertion and engagement of the first and second connectors to drive the crossbeam assembly and the side plate closer together. The guide surface offset from the height direction of the lifting table provides guidance, allowing the first and second connectors to be smoothly inserted and reducing the probability of interference. The guide surface is subjected to pressure during the insertion of the first and second connectors. Because the guide surface is offset from the height direction of the lifting table, the pressure on the guide surface has a component along the horizontal direction of the lifting table, thereby bringing the crossbeam assembly and the side plate closer together and improving the structural stability of the lifting table.

[0033] Furthermore, the crossbeam assembly is also equipped with a controller and a first power interface for electrical connection to the controller, while the lifting column is equipped with a second power interface. The first power interface cooperates with the second power interface during the connection of the lifting column to the crossbeam assembly. The controller can supply power to the lifting column and send control commands to control the lifting column's lifting movement. During the process of fixing the crossbeam assembly and side plate to the tabletop, the lifting column simultaneously completes its electrical connection with the controller. This eliminates the need to connect the controller and the lifting column after assembly, or to electrically connect the lifting column to the controller before assembly, thus facilitating user assembly and disassembly.

[0034] Furthermore, the crossbeam assembly is also provided with a cover plate, on which the first power interface is mounted. The cover plate can fix the first power interface, preventing changes in its position and allowing the first and second power interfaces to cooperate smoothly.

[0035] Furthermore, the lifting columns are provided in two locations, respectively at both ends of the crossbeam assembly. The crossbeam assembly is also equipped with a motor and a transmission mechanism connected to the motor. The transmission mechanism is in transmission cooperation with the two lifting columns. The height-adjustable table of this application can simultaneously drive both lifting columns to perform lifting movements using a single motor. The motor can transmit power to both lifting columns simultaneously through the transmission mechanism. During the process of fixing the crossbeam assembly and side panels to the tabletop, the lifting columns also complete their transmission cooperation with the transmission mechanism, facilitating user assembly and disassembly.

[0036] Furthermore, there are two lifting columns located at both ends of the crossbeam assembly, and a column crossbeam is provided between the two lifting columns. A controller electrically connected to the two lifting columns is provided on the column crossbeam.

[0037] Furthermore, the crossbeam assembly and the side plate are spliced ​​to form a socket for the insertion of the lifting column. The lifting column mates with the side wall of the socket to position the crossbeam assembly and the side plate in the horizontal direction of the lifting table. The structure in which the lifting column mates with the crossbeam assembly and the side plate can be provided on the side wall of the socket to conceal the assembly structure.

[0038] Furthermore, one of the side plate and the crossbeam assembly has an opening, and the other is inserted into the opening to form the socket; or, one of the side plate and the crossbeam assembly has a first notch, and the other has a second notch at one end inserted into the first notch, the first notch and the second notch forming the socket.

[0039] Furthermore, the side panel is provided with a first notch, and the crossbeam assembly includes a first crossbeam and a second crossbeam slidably mounted at both ends of the first crossbeam. The end of the second crossbeam is provided with a second notch. The side panel slides relative to the tabletop in a first direction, and the second crossbeam slides relative to the tabletop in a second direction perpendicular to the first direction to insert into the first notch. The first notch and the second notch form a socket for the lifting column to be inserted. The inner walls of the first notch and the second notch are provided with a first guide block, and the lifting column is provided with a second guide block that engages with the first guide block. The inner wall of the second notch is also provided with an elastic locking tongue, and the side wall of the lifting column is provided with a locking hole that engages with the elastic locking tongue. When the second crossbeam is inserted into the first notch, the second crossbeam has a limiting effect on the side panel, preventing the side panel from sliding along the first direction and separating from the tabletop. The lifting column is inserted into the socket. During insertion, the first guide block and the second guide block engage. The first guide block on the side plate restricts the movement of the lifting column in the second direction. The lifting column cooperates with the first guide block on the second crossbeam to restrict the sliding of the second crossbeam in the second direction, thereby fixing the crossbeam assembly and the side plate. During the insertion of the lifting column into the socket, the elastic locking tongue can be deformed and inserted into the lock hole, thereby restricting the positional change of the lifting column in the height direction of the lifting table. The lifting column is fixed, and the position of the crossbeam assembly and the side plate is also locked based on the fixed lifting column.

[0040] Furthermore, the crossbeam assembly slides along a first direction to engage the first mounting hole with the first positioning post, and at least one side plate of the crossbeam assembly slides along a second direction deviating from the first direction to engage the second mounting hole with the second positioning post. After the side plate mounted on the tabletop along the second direction is locked to the crossbeam assembly by the lifting column, the side plate and crossbeam assembly cannot disengage from the tabletop. Thus, even if the other side plate of the crossbeam assembly engages with the tabletop along the first direction, it remains fixed to the tabletop after being locked by the lifting column. Of course, if both side plates of the crossbeam assembly engage with the tabletop in directions different from the first direction, the stability of the height-adjustable table will be even better.

[0041] Furthermore, the crossbeam assembly includes a first crossbeam and a second crossbeam slidably mounted at both ends of the first crossbeam. The side plate slides in a direction offset from the second crossbeam relative to the first crossbeam, causing the second mounting hole to engage with the second positioning post. The second crossbeam can slide relative to the first crossbeam to adjust the length of the crossbeam assembly, thereby adapting the crossbeam assembly to various sizes of tabletops and improving its adaptability. The engagement direction between the side plate and the tabletop and the second crossbeam and the tabletop are different, thus preventing the side plate and crossbeam assembly from disengaging from the tabletop after being locked by the lifting column.

[0042] Furthermore, the first positioning hole includes a first insertion end and a first positioning end, and the first positioning post includes a first small diameter section and a first large diameter section. The size of the first large diameter section is larger than the size of the first positioning end. The first positioning post is inserted from the first insertion end and passes through the first positioning hole. The first small diameter section slides from the first insertion end to the first positioning end to axially limit the first positioning post. Since the size of the first large diameter section is larger than the size of the first positioning end, when the first small diameter section slides from the first insertion end to the first positioning end, the first positioning post cannot move in its own axial direction to move out of the first positioning hole. The axial direction of the first positioning post is the height direction of the lifting table. In this way, the positional change of the crossbeam assembly relative to the tabletop in the height direction of the lifting table can be limited.

[0043] Furthermore, the first positioning hole includes a first insertion end and a first positioning end, and the first positioning post includes a first small diameter section and a first large diameter section. The size of the first large diameter section is larger than the size of the first positioning end. The first positioning post is inserted from the first insertion end and passes through the first positioning hole. The first small diameter section slides from the first insertion end to the first positioning end to axially limit the first positioning post. Since the size of the second large diameter section is larger than the size of the second positioning end, when the second small diameter section slides from the second insertion end to the second positioning end, the second positioning post cannot move in its own axial direction to move out of the second positioning hole. The axial direction of the second positioning post is the height direction of the lifting table. In this way, the positional change of the side panel relative to the tabletop in the height direction of the lifting table can be limited.

Detailed Implementation Methods

[0069] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0070] The terms "exemplary" and "some embodiments" used below are meant to be "used as examples, embodiments, or illustrations," and any embodiment described as "exemplary" is not necessarily to be construed as superior to or better than other embodiments. Numerous specific details are set forth in the following detailed description to better illustrate the invention, and those skilled in the art will understand that this disclosure can be practiced without certain specific details.

[0071] Reference Figures 1 to 5 This invention discloses a conveniently installed height-adjustable table, including a tabletop 100, a lifting column 200, a crossbeam assembly 300, and side plates 400 located at both ends of the crossbeam assembly 300. The lifting column 200, crossbeam assembly 300, and side plates 400 are detachably mounted on the tabletop 100. The crossbeam assembly 300 and side plates 400 on the tabletop 100 can support the tabletop 100, increasing its strength and preventing it from bending. The lifting column 200 can drive the tabletop 100 to perform lifting movements to adjust its height.

[0072] The tabletop 100 and the crossbeam assembly 300 are provided with a first positioning hole 500 and a first positioning post 510, respectively. The first positioning hole 500 includes a first insertion end 501 and a first positioning end 502. The first positioning post 510 includes a first large diameter section 511 and a first small diameter section 512. The first large diameter section 511 is inserted into the first insertion end 501 and slides relative to it, so that the first small diameter section 512 slides to the first positioning end 502 to position the crossbeam assembly 300 in the height direction of the lifting table.

[0073] The tabletop 100 and the side panel 400 are provided with a second positioning hole 520 and a second positioning post 530, respectively. The second positioning hole 520 includes a second insertion end 521 and a second positioning end 522. The second positioning post 530 includes a second large diameter section 531 and a second small diameter section 532. The second large diameter section 531 is inserted into the second insertion end 521 and slides relative to it, so that the second small diameter section 532 slides to the second positioning end 522 to position the side panel 400 in the height direction of the lifting table.

[0074] One end of the lifting column 200 is connected to the crossbeam assembly 300 and the side plate 400 to limit the sliding of the crossbeam assembly 300 and the side plate 400 relative to the tabletop 100. The other end of the lifting column 200 is detachably equipped with a foot assembly 201. The foot assembly 201 is used to support the lifting table on the ground, maintaining the stability of the lifting table and preventing it from tipping over. The foot assembly 201 can be separated from the lifting column 200. During transportation, the tabletop 100, side plate 400, crossbeam assembly 300, lifting column 200, and foot assembly 201 can be packaged separately to reduce transportation costs.

[0075] The crossbeam assembly 300 and the side plate 400 can be installed on the tabletop 100 by engaging with the first positioning hole 500 and the first positioning post 510, and with the second positioning hole 520 and the second positioning post 530. After the two are engaged with the tabletop 100, the crossbeam assembly 300 and the side plate 400 can be suspended on the tabletop 100. The lifting column 200 locks the crossbeam assembly 300 and the side plate 400 together, connecting them into a whole so that they cannot move relative to each other, thus keeping them in their current position and fixing the crossbeam assembly 300, the side plate 400 and the tabletop 100 together. The crossbeam assembly 300 and the side plate 400 can be installed on the tabletop 100 without screws, making them easy to install and remove for user convenience. Furthermore, the lifting column 200 connects the crossbeam assembly 300 and the side plate 400 for positioning. No additional structure is needed between the crossbeam assembly 300 and the side plate 400 to lock them together. At the same time, the lifting column 200 is also fixed to the tabletop 100, further reducing the assembly steps of the lifting table.

[0076] When assembling the crossbeam assembly 300 onto the tabletop 100, first align the first positioning pin 510 with the first positioning hole 500 and insert it into the first positioning hole 500. Then, the crossbeam assembly 300 slides relative to the tabletop 100, allowing the first positioning hole 500 to position the first positioning pin 510, thus preventing the crossbeam assembly 300 from moving in the height direction of the lifting table. For disassembly, simply slide the crossbeam assembly 300 in the reverse direction to release the positioning of the first positioning hole 500 on the first positioning pin 510. The fit between the side panel 400 and the tabletop 100 is the same as the fit between the crossbeam assembly 300 and the tabletop 100.

[0077] The first positioning hole 500, the first positioning post 510, the second positioning hole 520, and the second positioning post 530 are pre-installed on the lifting table at the factory, eliminating the need for additional installation of the first positioning post 510 and the second positioning post 530. This reduces the installation work for the user and also improves the positional accuracy of the crossbeam assembly 300 and the side plate 400 on the tabletop 100, ensuring the support performance of the tabletop 100.

[0078] Preferably, the first positioning hole 500 is provided on the crossbeam assembly 300, the second positioning hole 520 is provided on the side plate 400, and the first positioning post 510 and the second positioning post 530 are provided on the tabletop 100. The crossbeam assembly 300 and the side plate 400 can be provided with through-holes 500 and 520. If the first positioning hole 500 and the second positioning hole 520 are provided on the tabletop 100, then corresponding space needs to be provided inside the tabletop 100 so that the movement of the first large-diameter section 511 and the second large-diameter section 531 inside the tabletop 100 is not restricted. This design will increase the processing difficulty of the tabletop 100.

[0079] The first positioning hole 500 and the second positioning hole 520 are gourd-shaped holes (e.g., ...). Figure 5 As shown), the first insertion end 501 and the second insertion end 521 are the large holes of the gourd-shaped hole, and the first positioning end 502 and the second positioning end 522 are the small holes of the gourd-shaped hole. The first positioning hole and the second positioning hole can also be trapezoidal holes. In addition, the first positioning hole and the second positioning hole can also be holes open on one side. When the first positioning pin mates with the first positioning hole, the first positioning pin can slide into the first positioning hole from the open side (as shown). Figure 12 As shown, Figure 12 The image only shows the second positioning hole 400 as an open hole on one side. The image also shows the way the second positioning hole 400 and the second positioning post 410 are fitted together. The first positioning post 510 and the second positioning post 530 are equal-height screws pre-installed on the tabletop 100, ensuring that the side plate 400 and the crossbeam assembly 300 are at the same or nearly the same height after being assembled onto the tabletop 100. The optimal position is one where the side plate 400 and the crossbeam assembly 300 fit snugly against the tabletop 100, thus reducing the swaying of the side plate 400 and the crossbeam assembly 300 in the height direction of the lifting table.

[0080] To prevent the side panel 400 and the crossbeam assembly 300 from sliding together relative to the tabletop 100 after being connected via the lifting column 200, refer to... Figure 5 and Figure 7In one embodiment of the present invention, preferably, the crossbeam assembly 300 includes a first crossbeam 310 and a second crossbeam 320 slidably mounted at both ends of the first crossbeam 310. The side plate 400 slides in a direction that deviates from the extension and retraction of the second crossbeam 320 relative to the first crossbeam 310, so that the second positioning hole 520 engages with the second positioning post 530. The second crossbeam 320 slides relative to the first crossbeam 310, so that the first positioning hole 500 engages with the first positioning post 510.

[0081] The second crossbeam 320 can slide relative to the first crossbeam 310 to adjust the length of the crossbeam assembly 300, thereby adapting the crossbeam assembly 300 to various sizes of tabletops 100 and improving its adaptability. The mating direction between the side panel 400 and the tabletop 100 and the second crossbeam 320 and the tabletop 100 are different, so that after the side panel 400 and the crossbeam assembly 300 are locked by the lifting column 200, they cannot disengage from the limiting part of the tabletop 100.

[0082] The second crossbeam 320 slides relative to the first crossbeam 310 along the length of the tabletop 100. When the two second crossbeams 320 are engaged with the tabletop 100, their sliding directions relative to the first crossbeam 310 are opposite.

[0083] That is, the second crossbeam 320 on one side of the first crossbeam 310 slides along the first direction, and the second crossbeam 320 on the other side of the first crossbeam 310 slides along the second direction. The sliding direction of the side plate 400 deviates from the direction of extension and retraction of the second crossbeam 320 relative to the first crossbeam 310, meaning that the sliding direction of the side plate 400 forms an angle greater than 0° with either the first or second direction, preferably 90°. Alternatively, the sliding direction of the side plate 400 can also be the opposite of the sliding direction of the corresponding second crossbeam 320. That is, the second crossbeam 320 on one side of the first crossbeam 310 slides along the first direction, and the side plate 400 slides along the second direction; the second crossbeam 320 on the other side of the first crossbeam 310 slides along the second direction, and the side plate 400 slides along the first direction. In this way, the second crossbeam 320 and the side plate 400 can also form a good interlocking relationship after connection.

[0084] Reference Figure 6In another embodiment of the present invention, unlike the above embodiments, the crossbeam assembly 300 is fixed in shape. The crossbeam assembly 300 slides along a first direction to engage the first positioning hole 500 with the first positioning post 510. At least one side plate 400 of the crossbeam assembly 300 slides along a second direction deviating from the first direction to engage the second positioning hole 520 with the second positioning post 530. After the side plate 400 mounted on the tabletop 100 along the second direction and the crossbeam assembly 300 are locked by the lifting column 200, they cannot disengage from the tabletop 100. In this way, even if the side plate 400 at the other end of the crossbeam assembly 300 engages with the tabletop 100 along the first direction, it can remain fixed to the tabletop 100 after being locked with the crossbeam assembly 300. Of course, if the side plates 400 on both sides of the crossbeam assembly 300 engage with the limiting part of the tabletop 100 in a direction different from the first direction, the stability of the lifting table will be better. The second direction deviating from the first direction means that the second direction and the first direction can form an angle greater than 0°. Of course, if the second direction is opposite to the first direction, an interlock can also be formed between the side plate 400 and the crossbeam assembly 300.

[0085] Reference Figures 7 to 10 In one embodiment of the present invention, based on the above embodiment, the lifting column 200 is provided with a first connector 600, and the crossbeam assembly 300 and the side plate 400 are provided with a second connector 610 that can be inserted and cooperated with the first connector 600 to position the lifting column 200 in the horizontal direction of the lifting table. After the first connector 600 and the second connector 610 are engaged, the lifting column 200 cannot move in the horizontal direction of the lifting table, that is, the crossbeam assembly 300 and the side plate 400 are locked by the lifting column 200 and cannot slide relative to the table 100.

[0086] The lifting column 200 is also provided with a third connector 620, and the crossbeam assembly 300 and / or the side plate 400 are provided with a fourth connector 630 that can cooperate with the third connector 620 to position the lifting column 200 in the height direction of the lifting table. Through the cooperation of the first connector 600 and the second connector 610, the crossbeam assembly 300 and the side plate 400 are fixed to the table 100 by the lifting column 200. The cooperation of the fourth connector 630 and the third connector 620 can limit the lifting column 200, so that the lifting column 200 cannot move relative to the table 100 in the height direction of the lifting table. The lifting column 200 is held in the position that maintains the cooperation of the first connector 600 and the second connector 610, so that the structure of the lifting table remains stable. Since the crossbeam assembly 300 and the side plate 400 have been fixed by the lifting column 200, the lifting column 200 can be positioned by setting the fourth connector 630 on either the crossbeam assembly 300 or the side plate 400. If the fourth connector 630 is set on both the crossbeam assembly 300 and the side plate 400, the stability of the fit between the lifting column 200, the crossbeam assembly 300 and the side plate 400 can be further improved.

[0087] The fourth connector 630 is a resilient latch that can extend and retract horizontally or flip vertically. The third connector 620 is a lock hole that engages with the resilient latch. The resilient latch and the lock hole only need to be inserted; no locking mechanism is required within the lock hole. If the resilient latch is extendable, the lifting column 200 can push the resilient latch to deform during assembly until the lock hole aligns with it, at which point the resilient latch can return to its original position and engage with the lock hole. If the resilient latch is flippable, the lifting column 200 can push the resilient latch to flip during assembly and insert it into the lock hole. The user can operate the resilient latch to return it to its original position to disassemble the lifting column 200. The positions of the resilient latch and the lock hole can also be interchanged.

[0088] To ensure alignment of the locking hole with the resilient latch during the assembly of the lifting column 200, guide surfaces 640 on the first connector 600 and the second connector 610 are offset from the height direction of the lifting table. In other words, the first connector 600 and the second connector 610 function as guide blocks. The guide surface 640 is pressed during the insertion of the first connector 600 and the second connector 610 to drive the crossbeam assembly 300 and the side plate 400 closer together. The guide surface 640, offset from the height direction of the lifting table, provides guidance, allowing the first connector 600 and the second connector 610 to be smoothly inserted, reducing the probability of interference. The guide surface 640 is subjected to pressure during the insertion of the first connector 600 and the second connector 610. Because the guide surface 640 is offset from the height direction of the lifting table, the pressure has a component along the horizontal direction of the lifting table, causing the crossbeam assembly 300 and the side plate 400 to move closer together, thus improving the structural stability of the lifting table. It also allows the relative positions of the resilient latch and the locking hole to change, enabling alignment between them.

[0089] Unlike the above embodiments, in one embodiment of the present invention, a locking structure for locking the elastic locking tongue is provided in the lock hole. The elastic locking tongue is inserted into and locked into the lock hole, thereby fixing the lifting column and positioning the lifting column in the height direction of the lifting table. In this way, after the first connecting member and the second connecting member cooperate, the lifting column can be positioned not only in the horizontal direction of the lifting table, but also in the height direction of the lifting table, so that there is no need to set up an additional structure for positioning the lifting column in the height direction of the lifting table.

[0090] Reference Figures 11 to 13 Unlike the embodiments described above, in one embodiment of the present invention, the lifting column 200 is provided with a first through hole 650, and the crossbeam assembly 300 and the side plate 400 are provided with second through holes 660. A pin 670 passing through the first through hole 650 and the second through hole 660 is used to limit the lifting column 200 in the height direction of the lifting table. The lifting column 200 can be locked to the crossbeam assembly 300 and the side plate 400 through the cooperation of the first connector 600 and the second connector 610. When the pin 670 passes through the first through hole 650 and the second through hole 660, the pin 670 can limit the displacement of the lifting column 200 in the radial direction of the pin 670.

[0091] Since the crossbeam assembly 300 and the side plate 400 are fixed by the lifting column 200, providing a second through hole 660 on either of them will allow the lifting column 200 to be positioned after the pin 670 is installed. However, the preferred solution is to provide a second through hole 660 on both the crossbeam assembly 300 and the side plate 400, which can improve the stability of the fit between the lifting column 200, the crossbeam assembly 300, and the side plate 400. In addition, due to the presence of the guide surface 640, the first connecting member 600 and the second connecting member 610 can align the first through hole 650 and the second through hole 660 during the fit process, so that the pin 670 can smoothly pass through the first through hole 650 and the second through hole 660.

[0092] Two sets of first through holes 650 and second through holes 660 are provided on the lifting column 200, the crossbeam assembly 300 and the side plate 400, so as to be fixed by two pins 670, which improves stability and prevents the lifting column 200 from tilting.

[0093] Reference Figure 3 and Figure 8 In one embodiment of the present invention, based on the above embodiment, the side plate 400 and the crossbeam assembly 300 can form an insertion port 700 for the lifting column 200 to be inserted after they are engaged with the table 100. The second crossbeam 320 can slide relative to the first crossbeam 310 along the first direction, and the side plate 400 can slide relative to the table 100 along the second direction perpendicular to the first direction.

[0094] The side plate 400 is provided with a first notch 410, and the second crossbeam 320 is inserted into the first notch 410. The second crossbeam 320 is also provided with a second notch 330. The first notch 410 and the second notch 330 form the aforementioned insertion port 700. When the second crossbeam 320 is inserted into the first notch 410, the second crossbeam 320 can limit the side plate 400 and restrict the sliding of the side plate 400 in the second direction.

[0095] The second connector 610 on the side plate 400 is located on the side wall of the first notch 410, and the second connector 610 on the crossbeam assembly 300 is located on the side wall of the second notch 330. When the second crossbeam 320 is inserted into the first notch 410, the second connector 610 on the side plate 400 is located at the end of the second notch 330, and the two second connectors 610 are in relative positions. On the second crossbeam 320, elastic locking tongues are provided on both sides of the second connector 610. The side wall of the second notch 330 is provided with a first opening 340 corresponding to the elastic locking tongue. The elastic locking tongue can extend from the first opening 340 and engage with the lock hole on the lifting column 200. The second crossbeam 320 is also provided with a second opening 350 corresponding to the other end of the elastic locking tongue. The user can press the elastic locking tongue through the second opening 350 to move the elastic locking tongue out of the lock hole and release the lock on the lifting column 200, thereby disassembling the lifting table. During assembly, when the lifting column 200 is inserted into the socket 700, it pushes the elastic locking tongue to deform. During the engagement with the second connector 610, the second crossbeam 320 moves closer to the side plate 400 to adjust the position of the elastic locking tongue in the first direction, so that the elastic locking tongue can be aligned with the lock hole. The structure in which the lifting column 200 engages with the crossbeam assembly 300 and the side plate 400 is set on the side wall of the socket 700, which can hide the assembly structure.

[0096] Reference Figure 5 and Figure 9 In one embodiment of the present invention, based on the above embodiment, a cover plate 360 ​​is also provided on the second crossbeam 320, and the lifting table also includes a controller. The controller can supply power to the lifting column 200 and send control commands to control the lifting movement of the lifting column 200. The controller is located between one of the second crossbeams 320 and the cover plate 360. The cover plate 360 ​​is fixedly installed on the second crossbeam 320 and can hide the controller inside.

[0097] The controller needs to be electrically connected to the lifting column 200. A first power interface 370 is also provided on the crossbeam assembly 300. The first power interface 370 is electrically connected to the controller. A second power interface 210 is provided at the end of the lifting column 200. The second power interface 210 can be plugged into the first power interface 370 to complete the electrical connection and signal connection between the lifting column 200 and the controller.

[0098] The first power interface 370 extends into the socket 700 to cooperate with the lifting column 200 during its insertion into the socket 700. This simplifies the connection between the lifting column 200 and the controller, eliminating the need to connect the controller and the lifting column 200 after assembly, or to electrically connect the lifting column 200 to the controller before assembly, thus facilitating user assembly and disassembly. The first connector 600 and the second connector 610 also ensure that the first power interface 370 and the second power interface 210 can be aligned to avoid damage to the pins on the two power interfaces.

[0099] In order to enable the first power interface 370 and the second power interface 210 to cooperate smoothly, the cover plate 360 ​​extends into the socket 700, and the first power interface 370 is fixed on the cover plate 360. In this way, the first power interface 370 is supported by the cover plate 360, so that the position of the first power interface 370 will not change during the cooperation with the second power interface 210, and the contact between the two power interfaces will not be unstable.

[0100] Reference Figure 5 and Figure 14 In one embodiment of the present invention, based on the above embodiment, a fixing block 380 is slidably installed on the first crossbeam 310. The fixing block 380 is connected to the end of the second crossbeam 320 away from the side plate 400. The fixing block 380 can limit the sliding distance of the second crossbeam 320 relative to the first crossbeam 310, so that the second crossbeam 320 remains connected to the first crossbeam 310. At the same time, it can also prevent the crossbeam assembly 300 from bending due to low fit strength between the second crossbeam 320 and the first crossbeam 310.

[0101] The fixing block 380 and the second crossbeam 320 are respectively disposed on the upper and lower sides of the first crossbeam 310. The first crossbeam 310 is provided with a through groove 381. The fixing block 380 and the second crossbeam 320 are connected by a connecting post 382 passing through the through groove 381. The fixing block 380 and the first crossbeam 310 are fitted with a clearance fit. The fixing block 380 can limit the distance between the first crossbeam 310 and the second crossbeam 320 in the height direction of the lifting table, so that there is no large gap between the first crossbeam 310 and the second crossbeam 320 that would affect the user's use. The small contact area between the fixing block 380 and the first crossbeam 310 can improve the smoothness of the sliding process of the second crossbeam 320 relative to the first crossbeam 310.

[0102] To improve the stability of the crossbeam assembly 300 on the tabletop 100, a third positioning post 540 is also provided on the tabletop 100. The third positioning post 540 is also a height-equalizing screw. The third positioning post 540 includes a third large-diameter section 541 and a third small-diameter section 542. The fixing block 380 is provided with a through groove 383. The cross section of the groove 383 is convex. The third large-diameter section 541 of the third positioning post 540 can slide into the groove 383 from the side, thereby positioning the fixing block 380. The fixing block 380 connects to the second crossbeam 320 and clamps the first crossbeam 310 between the two, thereby positioning the second crossbeam 320 and the first crossbeam 310.

[0103] On the fixed block 380, cable management channels 384 are provided on both sides of the slide groove 383, and the wires connecting the controller and the first power interface 370 can pass through the cable management channels 384.

[0104] Unlike the above embodiments, in another embodiment of the present invention, there are two lifting columns located at both ends of the crossbeam assembly. The crossbeam assembly is also provided with a motor and a transmission mechanism connected to the motor. The transmission mechanism is in transmission cooperation with the two lifting columns.

[0105] In this embodiment, the height-adjustable desk can be driven by a single motor to simultaneously move two lifting columns. The motor can transmit power to both lifting columns simultaneously through a transmission mechanism. While the lifting columns are fixing the crossbeam assembly and side panels to the desk, they also complete the transmission cooperation with the transmission mechanism to facilitate user assembly and disassembly.

[0106] Reference Figure 15 Unlike the above embodiments, in another embodiment of the present invention, there are two lifting columns 200 located at both ends of the crossbeam assembly 300, and a column crossbeam 220 is provided between the two lifting columns 200. A controller electrically connected to the two lifting columns 200 is provided on the column crossbeam 220.

[0107] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
