Description

Technical Field

[0001] This utility model relates to the field of electric height-adjustable desks, and in particular to an electric height-adjustable desk that is easy to assemble. Background Technology

[0002] With the improvement of living standards, the popularity of electric height-adjustable desks is constantly increasing. An electric height-adjustable desk consists of a tabletop and a frame. The frame includes a crossbeam and two electric uprights. The electric uprights can extend and retract to control the height of the tabletop and meet the user's needs. The crossbeam connects the two electric uprights, ensuring a constant distance between them to prevent the tabletop from deforming under the weight of heavy objects.

[0003] The existing electric column of the electric height-adjustable desk includes a sleeve assembly, a transmission assembly located within the sleeve assembly, a base box installed on top of the sleeve assembly, and a motor installed within the base box. The motor drives the sleeve assembly to extend and retract through the transmission assembly. When assembling the desk frame, the base box needs to be installed in the cavity of the crossbeam. The front and rear side walls of the base box are fixed to the crossbeam with two screws each to ensure the reliability of the installation of the electric column and the crossbeam. That is, the existing electric column and crossbeam assembly not only requires screws on both sides, but also has a large number of screws, which results in slow assembly speed and affects the assembly experience. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, this utility model provides an electric height-adjustable table that is easy to assemble, which can improve assembly efficiency and thus enhance the assembly experience.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] An easy-to-assemble electric height-adjustable desk includes a tabletop and a frame for supporting the tabletop. The frame includes a crossbeam and two electric uprights at both ends of the crossbeam. The electric uprights are installed at both ends of the crossbeam. Each electric upright includes a sleeve assembly, a transmission assembly, and a motor located within the sleeve assembly. The motor drives the sleeve assembly to extend and retract via the transmission assembly. The top of the sleeve assembly is provided with a plug-in seat, and the end of the crossbeam is provided with a socket. The plug-in seat engages with the socket along the length of the crossbeam. At least one first fastener passes through the plug-in seat along the length of the crossbeam and connects to the socket, so that the plug-in seat and the socket remain in the plugged-in state.

[0007] In the aforementioned easy-to-assemble electric lifting table, the plug-in base includes a plug-in portion extending along the length direction of the crossbeam and a connecting portion extending along the width direction of the crossbeam. The connecting portion is connected to the plug-in portion. The socket includes a socket portion that plugs into the plug-in portion and a mounting portion that is connected to the socket portion. The first fastener passes through the connecting portion and is fixedly connected to the mounting portion.

[0008] In the aforementioned easy-to-assemble electric lifting table, the plug-in part includes two plug-in plates spaced apart along the width direction of the crossbeam, the connecting part connects one end of the two plug-in plates, the other end of the two plug-in plates forms an installation port for the first fastener to pass through, the socket part includes a socket plate that is plugged into the two plug-in plates one by one, the mounting part connects the two socket plates, and the plug-in part is located between the two socket plates.

[0009] In the aforementioned easy-to-assemble electric lifting table, one of the plug-in plate and the socket plate is provided with a slot extending along the length of the crossbeam, and the other is provided with a plug block, the slot and the plug block being plugged in and engaged.

[0010] In the aforementioned easy-to-assemble electric height-adjustable desk, the electric height-adjustable desk also includes a decorative panel, which is installed on the plug-in socket to cover the mounting opening.

[0011] In the aforementioned easy-to-assemble electric lifting table, the crossbeam has a cable routing cavity and a controller located in the cable routing cavity. The controller is electrically connected to an electrical connector that routes the cable within the cable routing cavity, and the electrical connector is electrically connected to the motor.

[0012] In the aforementioned easy-to-assemble electric lifting table, at least one of the plug-in sockets is provided with a first adapter that is electrically connected to the motor, and the socket is provided with a second adapter that is electrically connected to the electrical connector. The first adapter and the second adapter are aligned by the plug-in socket and the socket being plugged in, and an electrical connection is established simultaneously when the plug-in socket and the socket are plugged in.

[0013] In the aforementioned easy-to-assemble electric height-adjustable table, the second adapter has conductive contacts, the first adapter includes a body and an elastic conductive sheet disposed on the body, the plug-in seat has a cavity with an open top forming an opening, the body is disposed in the cavity through the opening, and the elastic conductive sheet penetrates the wall of the cavity and is exposed on the outside of the cavity to contact the conductive contacts to draw electricity.

[0014] In the aforementioned easy-to-assemble electric lifting table, both of the plug-in sockets have open-top recesses forming cavities. The side wall of the cavity facing the controller has a through hole. The electrical connector passes through the socket, the through hole, and the bottom wall of the cavity in sequence before being electrically connected to the motor.

[0015] In the aforementioned easy-to-assemble electric lifting table, the bottom of the socket is provided with a clearance notch, the plug is located within the clearance notch, and the socket is supported on the plug to cover and shield the opening.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] 1. In the assembly of the electric column and crossbeam in this utility model, the plug-in base is first inserted into the socket along the length of the crossbeam, thus completing the initial positioning of the plug-in base and socket, reducing the alignment time of the first fastener. Since the first fastener passes through the plug-in base and connects to the socket along the length of the crossbeam, keeping the plug-in base and socket in an inserted state, only unidirectional locking is required. Compared with the existing double-sided locking (i.e., bidirectional locking), the assembly efficiency is significantly improved, thereby enhancing the assembly experience. In addition, during disassembly, the electric column can be slid out simply by loosening the first fastener, without the need to completely remove the screws on both sides as with the L-shaped base box, thus facilitating the disassembly of the table frame. Finally, most of the load borne by the tabletop can be directly transferred to the plug-in base through the insertion of the socket and the plug-in base, reducing the shear stress on the first fastener. Therefore, the first fastener mainly bears tensile stress rather than composite stress, extending the service life of the first fastener.

[0018] 2. The socket includes a plug-in portion extending along the length of the crossbeam and a connecting portion extending along the width of the crossbeam. The connecting portion connects to the plug-in portion. The socket includes a socket portion that engages with the plug-in portion and a mounting portion that connects to the socket portion. A first fastener passes through the connecting portion and is fixedly connected to the mounting portion. This design, by extending the plug-in portion along the length of the crossbeam, forms a continuous bearing surface, thereby improving its resistance to lateral torsion. Simultaneously, because the crossbeam is relatively long, the length of the plug-in portion can be reasonably increased to enhance the connection reliability between the socket and the socket.

[0019] 3. The insertion part includes two insertion plates spaced apart along the width of the crossbeam. The connecting part connects one end of the two insertion plates, and the other end of the two insertion plates forms an installation port for the first fastener to pass through. The socket part includes a socket plate that interlocks with each of the two insertion plates. The mounting part connects the two socket plates, and the insertion part is located between the two socket plates. This design, using the cooperation of double insertion plates and double socket plates, enhances the reliability of the insertion between the insertion socket and the socket. It also automatically corrects the perpendicularity of the electric column and the crossbeam when the insertion socket is inserted, reducing installation deviation. Finally, the design of the installation port facilitates the assembler's operation of the first fastener to connect the connecting part and the mounting part, reducing the assembly difficulty of the first fastener.

[0020] 4. One of the plug-in plate and the socket plate has a slot extending along the length of the crossbeam, and the other has a plug block. The slot and the plug block are inserted and mated. This design is simple in structure and easy to process and form.

[0021] 5. The electric height-adjustable desk also includes a decorative panel, which is installed on the connector to cover the mounting opening. By covering the mounting opening and the first fastener with the decorative panel, the appearance of the desk frame can be made cleaner; in addition, it can prevent dust and other foreign objects from entering and jamming the transmission assembly.

[0022] 6. At least one of the plug-in sockets is equipped with a first adapter for electrical connection to the motor, and the socket is equipped with a second adapter for electrical connection to the electrical connector. The first and second adapters are aligned by the insertion of the plug-in socket and the socket, and the electrical connection is established simultaneously when the plug-in socket and the socket are in place. This design allows for the alignment and electrical connection of the first and second adapters while the motorized column and beam are being mechanically installed, eliminating the need for additional wiring to achieve the electrical connection between the two. This reduces the safety risks caused by incorrect connections and improves the ease of installation.

[0023] 7. The second adapter has conductive contacts. The first adapter includes a body and an elastic conductive sheet disposed on the body. The plug-in socket has a cavity with an open top, and the body is disposed in the cavity through the opening. The elastic conductive sheet penetrates the wall of the cavity and protrudes to the outside of the cavity to contact the conductive contacts for power extraction. This design can automatically compensate for assembly errors through the elastic deformation of the elastic conductive sheet, thereby reducing the requirements for the production and assembly precision of each component; in addition, it also ensures that the power connection remains reliable and will not be interrupted when lifting or encountering a collision.

[0024] 8. The bottom of the socket has a clearance notch, and the plug seat is located within the clearance notch. The socket is supported on the plug seat to cover and conceal the opening. This design allows for easy assembly of the first adapter into the plug seat, while the partial support of the socket on the plug seat and the covering of the opening not only seals the cavity to prevent foreign objects from entering through the opening, but also eliminates the need for an additional cover plate. Furthermore, the support of the plug seat on the socket ensures that most of the load on the beam is directly transferred to the plug seat, reducing the shear stress on the first fastener and thus extending its service life.

[0041] This utility model provides an easily assembled electric height-adjustable table, including a tabletop and a table frame for supporting the tabletop. The table frame includes a crossbeam and two electric uprights at both ends of the crossbeam. The electric uprights are installed at both ends of the crossbeam. Each electric upright includes a sleeve assembly, a transmission assembly, and a motor located within the sleeve assembly. The motor drives the sleeve assembly to extend and retract through the transmission assembly. The top of the sleeve assembly is provided with a plug-in seat, and the end of the crossbeam is provided with a socket. The plug-in seat is plugged into the socket along the length of the crossbeam. At least one first fastener passes through the plug-in seat along the length of the crossbeam and connects to the socket, so that the plug-in seat and the socket remain in a plugged-in state.

[0042] In this invention, when assembling the electric column and crossbeam, the plug-in base is first inserted into the socket along the length of the crossbeam, thus completing the initial positioning of the plug-in base and socket, reducing the alignment time of the first fastener. Since the first fastener passes through the plug-in base and connects to the socket along the length of the crossbeam, keeping the plug-in base and socket in an inserted state, only unidirectional locking is required. Compared to existing double-sided locking (i.e., bidirectional locking), assembly efficiency is significantly improved, thus enhancing the assembly experience. Furthermore, during disassembly, the electric column can be slid out simply by loosening the first fastener, eliminating the need to completely remove the screws on both sides as with L-shaped base boxes, facilitating table frame disassembly. Finally, most of the load borne by the tabletop can be directly transferred to the plug-in base through the insertion of the socket and plug-in base, reducing the shear stress on the first fastener. Therefore, the first fastener primarily bears tensile stress rather than combined stress, extending its service life.

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0044] Example 1

[0045] Combination Figures 1 to 13As shown, in this embodiment, the electric lifting table includes a tabletop 100 and a table frame for supporting the tabletop 100. The table frame includes electric uprights 200 and a crossbeam 300. Two electric uprights 200 are installed at both ends of the crossbeam 300. The electric uprights 200 include a sleeve assembly 210, a transmission assembly, and a motor (not shown in the figure). The motor and the transmission assembly are both installed inside the sleeve assembly 210, and the motor is installed above the transmission assembly. The output shaft of the motor is coaxially arranged with the lead screw of the transmission assembly, and the two rotate synchronously. Thus, the motor can drive the sleeve assembly 210 to extend and retract through the transmission assembly. The specific structure of the transmission assembly and the connection method between the transmission assembly and the sleeve assembly 210 are existing technologies and will not be described in detail here.

[0046] In this embodiment, the top of the sleeve assembly 210 is provided with a plug-in seat 220. The sleeve assembly 210 includes an inner tube, a middle tube and an outer tube arranged sequentially from the inside to the outside. The bottom of the outer tube is fixedly connected to the foot 400, while the top of the inner tube is fixedly connected to the plug-in seat 220 by screws. The end of the crossbeam 300 is provided with a socket 500. The plug-in seat 220 is inserted into the socket 500 along the length of the crossbeam 300. The first fastener 600 passes through the plug-in seat 220 along the length of the crossbeam 300 and is connected to the socket 500 so that the plug-in seat 220 and the socket 500 are kept in the plugged-in state.

[0047] In this embodiment, when assembling the electric column 200 and the crossbeam 300, the plug-in base 220 is first inserted into the socket 500 along the length of the crossbeam 300. This completes the initial positioning of the plug-in base 220 and the socket 500, thereby reducing the alignment time of the first fastener 600. Since the first fastener 600 passes through the plug-in base 220 and connects to the socket 500 along the length of the crossbeam 300, keeping the plug-in base 220 and the socket 500 in an inserted state, only unidirectional locking is required. Compared to existing double-sided locking (i.e., bidirectional locking), this method is more efficient. In terms of locking, assembly efficiency is significantly improved, thereby enhancing the assembly experience. Furthermore, during disassembly, the electric column 200 can be slid out simply by loosening the first fastener 600, eliminating the need to completely remove the screws on both sides as required for the L-shaped base box, thus facilitating the disassembly of the table frame. Finally, most of the load borne by the tabletop 100 can be directly transferred to the plug-in socket 220 through the plug-in engagement between the socket 500 and the plug-in base 220, reducing the shear stress on the first fastener 600. As a result, the first fastener 600 mainly bears tensile stress rather than composite stress, extending the service life of the first fastener 600.

[0048] Specifically, in this embodiment, the socket 220 includes a plug-in portion 221 extending along the length of the crossbeam 300 and a connecting portion 222 extending along the width of the crossbeam 300. The connecting portion 222 is connected to the plug-in portion 221. The socket 500 includes a socket portion 510 that engages with the plug-in portion 221 and a mounting portion 520 connected to the socket portion 510. A first fastener 600 passes through the connecting portion 222 and is fixedly connected to the mounting portion 520. This design, by extending the plug-in portion 221 along the length of the crossbeam 300, forms a continuous bearing surface, thereby improving its resistance to lateral torsion. At the same time, since the crossbeam 300 is relatively long, the length of the plug-in portion 221 can be reasonably increased to enhance the connection reliability between the socket 220 and the socket 500.

[0049] In this embodiment, the insertion part 221 includes two insertion plates 2210 spaced apart along the width direction of the crossbeam 300. The connecting part 222 is a connecting plate that connects one end of the two insertion plates 2210. The other end of the two insertion plates 2210 forms an installation port 2201 through which the first fastener 600 passes. That is, the insertion plates and the connecting plates are connected to form a U-shaped structure. The insertion base 220 also includes a base plate 223. The insertion plates, the connecting plates, and the base plate 223 are fixedly connected to form an open top. The cavity 2202 is formed by forming an open cavity. Preferably, the plug plate, connecting plate and base plate 223 are integrally formed. The base plate 223 is fixedly connected to the inner tube by screws, thereby realizing that the plug seat 220 is installed on the top of the sleeve assembly 210. The socket part 510 includes two socket plates 511, which are respectively plugged into the two plug plates 2210. The mounting part 520 connects the two socket plates 511, and the plug part 221 is located between the two socket plates 511. This design, employing the cooperation of double plug-in plates 2210 and double socket plates 511, enhances the reliability of the plug-in socket 220 and the socket 500. It also automatically corrects the perpendicularity of the electric column 200 and the crossbeam 300 when the plug-in socket 220 is inserted, reducing installation deviation. Finally, the design of the mounting port 2201 facilitates the assembler's operation of the first fastener 600 to connect the connecting part 222 and the mounting part 520, reducing the assembly difficulty of the first fastener 600.

[0050] In this embodiment, the connecting part 222 is provided with two through holes 2221, and the mounting part 520 is provided with two threaded holes 521. The first fastener 600 is a screw, which passes through the through holes 2221 and the threaded holes 521 to lock it in place. In this way, two screws can be used to fix the plug-in socket 220 and the socket 500 so that the plug-in socket 220 and the socket 500 are kept in the plugged-in state. At the same time, there is no need to distinguish between the plug-in socket 220 and the socket 500 during assembly, which reduces the assembly requirements.

[0051] In this embodiment, two plug-in plates 2210 are located between two socket plates 511. One side of the plug-in plate 2210 facing the socket plate 511 has a slot 2211 extending along the length of the crossbeam 300. The other side of the socket plate 511 facing the plug-in plate 2210 has a protruding plug 5110 extending along the length of the crossbeam 300. The plug 5110 engages with the slot 2211. This design is simple and easy to manufacture. Furthermore, the end of the slot 2211 near the mounting opening 2201 is closed, while the end away from the mounting opening 2201 is open. This allows the plug 5110 to smoothly insert into the slot 2211 when the plug-in socket 220 is inserted into the socket 500. After the plug 5110 abuts against the closed end of the slot 2211, further insertion of the plug-in socket 220 is restricted, indicating that it is properly inserted.

[0052] It is understood that in other embodiments of this utility model, the plug plate is provided with plug blocks extending along the length direction of the crossbeam, and the socket plate is provided with slots, which are engaged with the plug blocks.

[0053] It is understood that in other embodiments of this utility model, the two socket plates may also be disposed between the two plug plates.

[0054] In this embodiment, the crossbeam 300 is a hollow metal tube with a wiring cavity 301 inside. A controller 700 is installed inside the wiring cavity 301. The controller 700 is electrically connected to two electrical connectors 710 that are running in the wiring cavity 301, which are powered by wires or plugs. The two electrical connectors 710 are electrically connected to the motors in the two electric columns 200 respectively. The controller 700 is connected to an external power source through a power plug 720 to power the motors and control the motors.

[0055] like Figure 6 and Figure 9As shown, a notch is cut off at the lower middle part of the end of the crossbeam 300 to form an L-shaped structure at the end of the crossbeam 300. The shape of the socket 500 matches the shape of the end of the crossbeam 300, that is, the shape of the socket 500 is L-shaped, so that an avoidance notch 501 is formed at the bottom of the socket 500. The socket 500 is fixedly installed in the wiring cavity 301 by screws, which makes the structure more compact. The bottom surface of the socket 500 located above the notch is provided with the aforementioned socket plate 511. In this way, after the plug-in seat 220 and the socket 500 are plugged in and engaged, the plug-in seat 220 can be inserted into the socket 500. The connector 220 is located within the clearance notch 501 so that the socket 500 is supported on the connector 220 and covers the opening of the cavity 2202. This allows the socket 500 to close the opening of the cavity 2202 to prevent foreign objects from entering through the opening, without the need for an additional cover plate to close the opening of the cavity 2202. At the same time, the support of the socket 500 by the connector 220 allows most of the load of the beam 300 to be directly transferred to the connector 220, thereby reducing the shear stress on the first fastener 600 and extending the service life of the first fastener 600.

[0056] The electric height-adjustable table in this embodiment also includes a decorative panel 800, which is mounted on the connector 220 to cover the mounting opening 2201. By covering the mounting opening 2201 and the first fastener 600 with the decorative panel 800, the appearance of the table frame can be made simpler; in addition, it can also prevent dust and other foreign objects from entering and jamming the transmission assembly. In order to realize the assembly of the decorative panel 800 and the connector 220, in this embodiment, after the connector 220 and the socket 500 are inserted into place, the connector 220 and the socket 500 cooperate to form a positioning groove located outside the mounting opening 2201, and the decorative panel 800 is interference-fitted into the positioning groove.

[0057] It is understood that in other embodiments of this utility model, the decorative panel may also be hinged to the plug socket, and after the first fastener connects the connecting part and the mounting part, the decorative panel is flipped over to cover and block the mounting opening.

[0058] like Figures 3 to 12 As shown, in this embodiment, the plug-in socket 220 of the left electric column 200 is provided with a first adapter 230 that is electrically connected to the wiring terminal 240 of the motor, and a second adapter 730 is fixed on the socket 500. The second adapter 730 is electrically connected to the electrical connector 710 on the left side. For ease of illustration, the structure of the second adapter 730 and the electrical connector 710 is shown below. Figure 6 and Figure 9The second adapter 730 and electrical connector 710 are initially separate, but become electrically connected after assembly. After assembly, the first adapter 230 and second adapter 730 remain electrically connected. The electrical connection direction between the first adapter 230 and second adapter 730 is the same as the insertion direction between the connector 220 and the socket 500. The insertion of the connector 220 into the socket 500 guides the alignment of the first adapter 230 and second adapter 730, and the electrical connection is established synchronously when the connector 220 and socket 500 are fully inserted. This design allows for the simultaneous mechanical installation of the electric column 200 and the crossbeam 300, achieving both alignment and electrical connection of the first adapter 230 and second adapter 730 without requiring additional wiring. This reduces safety risks due to incorrect connections and improves installation convenience.

[0059] In this embodiment, the second adapter 730 has conductive contacts. The first adapter 230 includes a body 231 and an elastic conductive sheet 232 disposed on the body 231. The body 231 is disposed in the cavity 2202 through an opening and is electrically connected to the motor. The connecting part 222 is provided with a through hole, and two through holes 2221 are provided on both sides of the through hole. The elastic conductive sheet 232 passes through the through hole and is exposed on the outside of the cavity 2202 to contact the conductive contacts to draw power. This design can automatically compensate for assembly errors through the elastic deformation of the elastic conductive sheet 232, thereby reducing the requirements for the production and assembly precision of each component. In addition, it also ensures that the power connection remains reliable and will not be interrupted when lifting or encountering a collision. Finally, the open design of the cavity 2202 facilitates the assembly of the first adapter 230 into the plug socket 220, thereby reducing the assembly difficulty of the first adapter 230.

[0060] And such Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, the plug-in socket 220 of the electric column 200 on the right has a through hole on the side wall of the cavity facing the controller 700, that is, the connecting part 222 also has a through hole, and the base plate 223 also has a through hole. In this way, the electrical connector 710 on the right passes through the socket 500, the through hole of the connecting part and the through hole of the bottom wall of the cavity 2202 in sequence and is electrically connected to the motor terminal 240.

[0061] Therefore, it can be seen that the electric lifting table in this embodiment uses internal wiring to realize the electrical connection between the controller 700 and the built-in motor of the electric column 200. The appearance is simple and clean, with no messy exposed cables, which avoids the user's legs from getting caught on the cables and causing poor electrical connection.

[0062] It should be noted that in other embodiments of this utility model, the plug-in socket of the right electric column is also provided with a first adapter that is electrically connected to the motor, and the socket on the right is also provided with a second adapter that is electrically connected to the right electrical connector. The first adapter and the second adapter on the right are electrically connected synchronously after the plug-in socket on the right and the socket on the right are plugged in. The connection method can refer to the connection between the left electric column and the left electrical connector. That is, both electric columns are electrically connected synchronously with the second adapter on the corresponding side after being plugged in, so as to further simplify the assembly difficulty of the electric lifting table.

[0063] It should be noted that in other embodiments of this utility model, the motors inside the two electric columns can also be directly electrically connected to the electrical connectors.

[0064] Finally, as Figure 1 and Figure 13 As shown, the table frame in this embodiment also includes auxiliary beams 900 and a U-shaped frame 1000. The U-shaped frame 1000 includes two parallel longitudinal sections and a transverse section welded between the two longitudinal sections. The ends of the two longitudinal sections are welded and fixed to both ends of the crossbeam 300, respectively. Multiple auxiliary beams 900 are spaced apart along the length of the crossbeam 300. One end of each auxiliary beam 900 is welded and fixed to the crossbeam 300, and the other end is welded and fixed to the transverse section of the U-shaped frame 1000. The tabletop 100 is supported on the auxiliary beams 900 and the U-shaped frame 1000. Some screws pass through the auxiliary beams 900 and are connected to the tabletop. The tabletop 100 is locked in place, with some screws passing through the U-shaped frame 1000 and locking it to the table frame. The top surface of the crossbeam 300 is at the same level as the top surface of the tabletop 100, so that the crossbeam 300 and the tabletop 100 together form the tabletop. This widens the tabletop without increasing the area of ​​the tabletop, thus reducing costs. In addition, with the height of the crossbeam 300 and the thickness of the tabletop 100 remaining unchanged, this design also reduces the size of the crossbeam 300 under the tabletop, reducing the risk of knees hitting the crossbeam 300.

[0065] It is understood that in other embodiments of this utility model, the inner tube of the sleeve assembly may also be fixedly connected to the foot, while the plug-in seat is fixedly installed on the top of the outer tube.

[0066] It is understood that in other embodiments of this utility model, the crossbeam may also be provided on the bottom surface of the tabletop, and the tabletop is supported by the crossbeam, auxiliary beam and U-shaped frame.

[0067] It is understood that in other embodiments of this utility model, the U-shaped frame can be omitted from the table frame, which simplifies the structure of the table frame and reduces the manufacturing cost of the electric height-adjustable table.

[0068] Example 2

[0069] like Figure 14 As shown, compared with Embodiment 1, the difference in this embodiment is that: a through hole 2221 is provided on the connecting part 222, and a threaded hole 521 is provided on the corresponding mounting part 520. A screw passes through the through hole 2221 and the threaded hole 521 to lock it in place. That is, a screw is used to fix the plug-in seat 220 and the socket 500 so that the plug-in seat 220 and the socket 500 are kept in the plugged-in state. This can minimize the number of first fasteners 600 and further simplify the assembly process.

[0070] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined in the claims of this utility model.
