Description

Technical Field

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

[0002] Existing electric height-adjustable desks on the market include a tabletop, two adjustable legs for supporting the tabletop, and a controller. Each adjustable leg includes a lifting column and feet installed at the bottom of the lifting column. The length of the feet extends along the front-to-back direction of the tabletop. The controller is located on the bottom surface of the tabletop between the two adjustable legs. The lifting column includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a motor connected to the transmission assembly. The motor is connected to a motor control line connected to the controller. The sleeve assembly has the feet at one end and a base box connected to the tabletop at the other. The base box is connected to the tabletop. A cable axially passes through one of the sleeve assemblies, with one end leading out of the base box and connected to the controller. The other end of the cable leads out through the rear of the sleeve assembly and connects to a power line. By connecting to an external power source via the power line, the adjustable legs can be connected to the power grid, allowing the controller to supply power to the motor and control its operation, thereby controlling the extension and retraction of the adjustable legs to control the tabletop's height.

[0003] The existing base box and sleeve assembly form an L-shaped column. After the lifting table legs and tabletop are assembled, the base box extends from the sleeve assembly to the other lifting table leg. As a result, users need to pay attention to the position of the two lifting table legs when assembling the electric lifting table to ensure that the cable outlet on the sleeve assembly faces the rear. If the left and right lifting table legs are swapped and rotated 180 degrees and installed backwards, the cable outlet on the sleeve assembly will face the user side. This increases the risk of the user's legs getting caught on the power cord or kicking the connection between the power cord and the sleeve assembly. In other words, the existing lifting table leg structure requires the assembler to ensure that the installation position of each lifting table leg is correct. If installed backwards, the lifting table legs need to be disassembled and reinstalled. This causes inconvenience to the assembler and reduces the user experience. Utility Model Content

[0004] To address the shortcomings and deficiencies of the existing technology, this utility model provides a lifting table leg for an electric height-adjustable desk and an electric height-adjustable desk. The position of the lifting table leg with cable can be adjusted according to different usage scenarios, and the direction of the foot assembly can be adjusted accordingly to achieve the rearward orientation of the first socket. There is no need to disassemble and reassemble the lifting column, which facilitates assembly and improves the user experience.

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

[0006] A height-adjustable table leg for an electric height-adjustable desk includes a height-adjustable column and a base assembly. The height-adjustable column includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a cable axially passing through the sleeve assembly. The sleeve assembly includes a first tube with a cable outlet. The base assembly includes a base connected to the first tube, a decorative cover on the base, and an adapter cable located inside the decorative cover. The decorative cover has an installation port for the lower end of the first tube to pass through in either a forward or reverse direction. The cable outlet is hidden inside the decorative cover. The decorative cover has a first socket exposed and facing one end of the base. One end of the adapter cable is electrically connected to the cable through the cable outlet, and the other end of the adapter cable is electrically connected to the first socket.

[0007] In the aforementioned electric height-adjustable desk legs, when the lower end of the first tube passes through the mounting opening in the forward direction, the cable outlet faces the first socket; when the lower end of the first tube passes through the mounting opening in the reverse direction, the cable outlet faces away from the first socket.

[0008] In the aforementioned electric height-adjustable table legs, a junction box is provided inside the first tube. The inner cavity of the junction box is provided with a second socket and an overload protection structure. One end of the cable is electrically connected to the second socket. The overload protection structure is connected to the terminal block of the live wire connected to the second socket. One end of the adapter cable is provided with a first plug that is inserted into the first tube through the outlet. The first plug is electrically connected to the second socket.

[0009] In the aforementioned electric height-adjustable table legs, the cable outlet is a through hole, and one end of the adapter cable passes through the cable outlet and is integrally connected to the cable.

[0010] In the aforementioned electric height-adjustable desk legs, the length of the base extends front to back. The first tube has a first mid-plane perpendicular to the length direction of the base and a second mid-plane extending along the length direction of the base. The front and rear side walls of the first tube are symmetrical about the first mid-plane, and the left and right side walls of the first tube are symmetrical about the second mid-plane.

[0011] In the aforementioned electric height-adjustable table legs, the sleeve assembly includes an inner tube, a middle tube, and an outer tube that are sequentially sleeved from the inside out, with the inner tube forming the first tube.

[0012] In the aforementioned electric height-adjustable desk legs, the decorative cover is a trapezoidal structure that gradually increases in size from top to bottom. The first socket is located on the side wall of the decorative cover facing the foot, and the mounting opening is located on the top wall of the decorative cover.

[0013] In the aforementioned electric height-adjustable table legs, the decorative cover and the base are integrally formed.

[0014] In the aforementioned electric height-adjustable desk legs, the base has a first end and a second end, and the distance between the first end and the lifting column is equal to the distance between the second end and the lifting column.

[0015] In addition, this utility model also discloses an electric height-adjustable table, including a tabletop and a first height-adjustable table leg and a second height-adjustable table leg spaced apart along the left and right directions of the tabletop. The first height-adjustable table leg adopts the height-adjustable table leg described in any of the above technical solutions. The sleeve assembly also includes a second tube, which is connected to the tabletop. The feet extend along the front and rear directions of the tabletop.

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

[0017] 1. In this utility model, the cable passes axially through the inside of the sleeve assembly, achieving concealed wiring, avoiding the clutter of exposed cables, and improving aesthetics. Furthermore, by setting a first socket on the decorative cover for cable connection, and connecting the first socket to an external power source via a power cord, different first sockets can be installed on the decorative cover to meet different customer needs and the usage scenario of the table. This allows users to adapt to different power cord specifications to accommodate devices from different regions or with special power signal requirements, thus improving the user experience. Additionally, after the height-adjustable table legs are assembled with the tabletop, the first socket must be positioned facing backward (towards the wall), as the decorative cover... The cover has an installation port for the lower end of the first tube to pass through in either the forward or reverse direction. Therefore, when the lifting table leg with cable is switched from the forward installation position (cable outlet facing backward) to the reverse installation position (cable outlet facing forward) due to being swapped with another lifting table leg without cable, the foot assembly with the first socket facing backward can still be adapted to the lifting column with the reverse installation. This eliminates the need to disassemble and reinstall the lifting column, making assembly easier for users. Finally, since the lifting table leg with cable can be swapped in both directions, the direction of the foot assembly can be adjusted to ensure that the first socket faces backward. Therefore, users can adjust the position of the lifting table leg with cable according to different usage scenarios to make the first socket closer to the external power source, thereby improving the user experience.

[0018] 2. A junction box is installed inside the first conduit. The junction box contains a second socket and an overload protection structure. One end of the cable is electrically connected to the second socket, and the overload protection structure is connected to the terminal block of the live wire connected to the second socket. One end of the adapter cable has a first plug that inserts into the first conduit through an outlet, and the first plug is electrically connected to the second socket. This design allows the first plug to be hidden inside the first conduit, preventing it from being exposed on the outside of the conduit. This reduces the size of the installation opening and minimizes dust entering the decorative cover. Furthermore, the overload protection structure is electrically connected to the terminal block of the live wire connected to the second socket. When the current exceeds a certain limit, the overload protection structure automatically trips, cutting off the circuit and preventing the wires from burning out due to overload. This effectively reduces the risk of short circuits and other damage to equipment and threats to personal safety, protecting the lifting column from overload current and ensuring product safety during use.

[0019] 3. The cable outlet is a through hole, with one end of the adapter cable passing through the outlet and connecting integrally with the cable. This design simplifies the connection structure between the adapter cable and the cable, thereby reducing the number of parts and further lowering manufacturing costs.

[0020] 4. The base extends along the front and back. The first tube has a first mid-section perpendicular to the base length and a second mid-section extending along the base length. The front and rear side walls of the first tube are symmetrical about the first mid-section, and the left and right side walls are symmetrical about the second mid-section. This design allows the lower end of the first tube to pass through the decorative cover's mounting opening in either the forward or reverse direction. The structure is simple, requiring only existing square or round tube lifting columns, reducing product modification costs.

[0021] 5. The sleeve assembly includes an inner tube, a middle tube, and an outer tube that are sequentially fitted together from the inside out, with the inner tube forming the first tube. This design reduces the size of the first tube, thereby reducing the size of the decorative cover and thus lowering manufacturing costs.

[0022] 6. The decorative cover is a trapezoidal structure that gradually increases in size from top to bottom. The first socket is located on the side wall of the decorative cover facing the bottom, and the mounting opening is located on the top wall of the decorative cover. With this design, while keeping the height of the decorative cover constant, the trapezoidal structure can effectively increase the area of ​​the rear side wall of the decorative cover compared to other shapes, thus providing sufficient space for the installation of the first socket.

[0023] 7. The decorative cover and the base are integrally formed. This design eliminates the need for separate assembly of the decorative cover and the base, thereby further improving assembly efficiency. In addition, the integral forming method also ensures good sealing between the bottom of the decorative cover and the base, preventing water from entering the decorative cover.

[0024] 8. The base has a first end and a second end. The distance between the first end and the lifting column is equal to the distance between the second end and the lifting column. This design ensures that even after the left and right lifting table legs are rotated 180 degrees to interchange positions, the space on both sides of the lifting column remains unchanged. This prevents the lifting column from being misaligned on the base, which could lead to a decrease in the space in front of the lifting column due to the interchange of the two lifting table legs, thus avoiding interference with the user's legs.

[0025] 9. An electric height-adjustable desk includes a tabletop and first and second height-adjustable legs spaced apart along the left and right sides of the tabletop. The first height-adjustable leg is as described in the above technical solution. The sleeve assembly further includes a second tube connected to the tabletop, and the feet extend along the front-back direction of the tabletop. This design allows the first height-adjustable leg to be switched from a forward installation position (cable outlet facing rearward) to a reverse installation position (cable outlet facing forward) by swapping its left and right sides with the second height-adjustable leg. The feet and decorative cover, with the first socket facing rearward, can still be adapted to the reverse-installed height-adjustable column, eliminating the need to disassemble and reassemble the height-adjustable column, thus facilitating user assembly. Finally, since the first height-adjustable leg can still ensure the first socket faces rearward after swapping its left and right sides with the second height-adjustable leg, users can adjust the position of the height-adjustable leg with the cable according to different usage scenarios, bringing the first socket closer to the external power source, thereby improving the user experience.

[0034] This utility model provides a lifting table leg for an electric height-adjustable desk, including a lifting column and a foot assembly. The lifting column includes a sleeve assembly, a transmission assembly for driving the sleeve assembly to extend and retract, and a cable axially passing through the sleeve assembly. The sleeve assembly includes a first tube with a cable outlet. The foot assembly includes a foot connected to the first tube, a decorative cover on the foot, and an adapter cable located inside the decorative cover. The decorative cover has an installation port for the lower end of the first tube to pass through in either a forward or reverse direction. The cable outlet is hidden inside the decorative cover. The decorative cover has a first socket exposed and facing the foot end. One end of the adapter cable is electrically connected to the cable through the cable outlet, and the other end of the adapter cable is electrically connected to the first socket.

[0035] In this invention, the cable passes axially through the inside of the sleeve assembly, achieving concealed wiring, avoiding the clutter of exposed cables, and improving aesthetics. Furthermore, by setting a first socket on the decorative cover for cable connection, and connecting the first socket to an external power source via a power cord, different first sockets can be installed on the decorative cover to meet different customer needs and the usage scenario of the table. This allows users to accommodate different power cord specifications to support devices from different regions or with special power signal requirements, thus improving the user experience. Additionally, after the height-adjustable table legs are assembled with the tabletop, the first socket must be positioned facing backward (towards the wall), as the decorative cover... The device features an installation port for the lower end of the first tube to pass through in either the forward or reverse direction. Therefore, when a height-adjustable table leg with a cable is swapped with another height-adjustable table leg without a cable, changing from a forward installation position (cable outlet facing backward) to a reverse installation position (cable outlet facing forward), the foot assembly with the first socket facing backward can still be adapted to the reverse-installed height-adjustable column. This eliminates the need to disassemble and reinstall the height-adjustable column, simplifying assembly for the user. Finally, since the height-adjustable table leg with a cable can be swapped left and right, the direction of the foot assembly can be adjusted to ensure the first socket faces backward. Therefore, users can adjust the position of the height-adjustable table leg with the cable according to different usage scenarios to bring the first socket closer to the external power source, thereby improving the user experience.

[0036] 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.

[0037] Example 1

[0038] Combination Figures 1 to 3 As shown, the electric height-adjustable desk leg 100 of this utility model includes a height-adjustable column 110 and a foot assembly. The height-adjustable column 110 includes a sleeve assembly, a transmission assembly (not shown in the figure) for driving the sleeve assembly to extend and retract, and a cable 111 axially passing through the sleeve assembly. The sleeve assembly includes a first tube 112 with a cable outlet 1120. The foot assembly includes a foot 120 connected to the first tube 112, a decorative cover 130 on the foot 120, and a converter cable 140 located inside the decorative cover 130. The decorative cover 130 has an installation port 131 for the lower end of the first tube 112 to pass through in either the forward or reverse direction. The cable outlet 1120 is hidden inside the decorative cover 130. The decorative cover 130 has a first socket 150 exposed and facing one end of the foot. One end of the converter cable 140 is electrically connected to the cable 111 through the cable outlet 1120, and the other end of the converter cable 140 is electrically connected to the first socket 150.

[0039] It should be noted that when the lower end of the first tube 112 passes through the mounting port 131 in the forward direction, the outlet 1120 is set towards the first socket 150; when the lower end of the first tube 112 passes through the mounting port 131 in the reverse direction, the outlet 1120 is set away from the first socket 150.

[0040] In this embodiment, the cable 111 passes through the inner axial direction of the sleeve assembly, achieving concealed wiring, avoiding the clutter of exposed cables, and improving aesthetics. Furthermore, by providing a first socket 150 on the decorative cover 130 to connect to the cable 111, and connecting the first socket 150 to an external power source via a power cord, different first sockets 150 can be provided on the decorative cover 130 to meet different customer needs and the usage scenario of the table. This allows users to adapt to different power cord specifications to accommodate devices from different regions or with special power signal requirements, thus improving the user experience. Additionally, after the lifting table legs 100 are assembled with the tabletop, the first socket 150 must be positioned facing backward (towards the wall). The cover 130 has an installation port 131 for the lower end of the first tube 112 to pass through in either the forward or reverse direction. Therefore, when the lifting table leg with cable is switched from the forward installation position (cable outlet facing backward) to the reverse installation position (cable outlet facing forward) due to the left-right swap with another lifting table leg without cable, the foot assembly of the first socket 150 facing backward can still be adapted to the lifting column facing backward. This eliminates the need to disassemble the lifting column 110 for reinstallation, making assembly easier for users. Finally, since the first socket 150 can be ensured to face backward by adjusting the direction of the foot assembly after the lifting table leg with cable is swapped, users can adjust the position of the lifting table leg with cable according to different usage scenarios to make the first socket 150 closer to the external power source, thereby improving the user experience.

[0041] The specific structure of the lifting column 110 in this embodiment can be referenced from the prior art CN221599451U. That is, the cable 111 is spiral-shaped. When the lifting column 110 extends, the pitch of the cable 111 increases to lengthen the whole structure. When the lifting column 110 shortens, the pitch of the cable 111 decreases to retract the whole structure. Therefore, the cable 111 will extend and retract with the extension and retraction of the lifting column 110.

[0042] The sleeve assembly in this embodiment includes an inner tube, a middle tube 113 and an outer tube 114 that are sequentially sleeved from the inside out. Unlike the prior art CN221599451U, the inner tube forms a first tube 112. This design can reduce the size of the first tube 112, thereby reducing the size of the decorative cover 130 and thus reducing manufacturing costs. The first tube 112 is detachably connected to the foot 120 by screws. The outer tube 114 is fixedly connected to the top box 160. The bottom box 160 can be fixed to the tabletop by screws. That is, the outer tube 114 is connected to the tabletop through the bottom box 160. The upper end of the cable 111 is led out through the bottom box 160 and connected to the controller. The bottom of the first tube 112 is provided with the aforementioned outlet 1120. The first tube 112 is provided with a junction box 170. The inner cavity of the junction box 170 is provided with a second socket 171 and an overload protection structure. The lower end of the cable 111 is electrically connected to the second socket 171. The overload protection structure is connected to the terminal of the live wire connected to the second socket 171. One end of the adapter cable 140 is provided with a first plug 141 that is inserted into the first tube 112 through the outlet 1120. The first plug 141 is electrically connected to the second socket 171. This design allows the first plug 141 to be hidden inside the first tube 112, preventing it from being exposed outside the tube 112. This reduces the size of the mounting opening 131 and minimizes dust entry into the decorative cover 130. Furthermore, the overload protection structure is electrically connected to the live wire terminal of the second socket 171. When the current exceeds the limit, the overload protection structure will automatically trip, cutting off the circuit and preventing the wires from burning out due to overload. This effectively reduces the risk of short circuits and other damage to equipment and threats to personal safety, protecting the lifting column from overload current and ensuring product safety during use.

[0043] In this embodiment, the length of the base 120 extends front to back. The first tube 112 has a first dividing surface O perpendicular to the length direction of the base 120 and a second dividing surface (not shown in the figure) extending along the length direction of the base 120. The second dividing surface is a vertical surface. The front sidewall 1121 and the rear sidewall 1122 of the first tube 112 are symmetrical about the first dividing surface O, and the left sidewall and the right sidewall of the first tube 112 are symmetrical about the second dividing surface. With this design, the lower end of the first tube 112 can penetrate the mounting port 131 of the decorative cover 130 in either the forward or reverse direction. The structure is simple, and existing square tube lifting columns or round tube lifting columns can be used, reducing product modification costs.

[0044] In this embodiment, the decorative cover 130 is a trapezoidal structure that gradually increases in size from top to bottom. The first socket 150 is located on the side wall of the decorative cover 130 facing the bottom, and the mounting opening 131 is located on the top wall of the decorative cover 130. With this design, while keeping the height of the decorative cover 130 constant, the trapezoidal structure effectively increases the area of ​​the side wall of the decorative cover 130 compared to other shapes, thus providing sufficient space for the installation of the first socket 150.

[0045] Preferably, the decorative cover 130 and the base 120 are integrally formed. This design eliminates the need for assembly steps between the decorative cover 130 and the base 120, thereby further improving the assembly efficiency of the base assembly. In addition, the integral forming method also ensures good sealing between the bottom of the decorative cover 130 and the base 120, preventing water from entering the decorative cover 130.

[0046] It is understood that in other embodiments of this utility model, the decorative cover can also be fixed to the base by means of screw connection, welding or fusion.

[0047] It is understood that in other embodiments of this utility model, the decorative cover may also be rectangular or hemispherical, etc.

[0048] In this embodiment, the foot 120 has a first end 121 and a second end 122. The distance between the first end 121 and the lifting column 110 is equal to the distance between the second end 122 and the lifting column 110. The first socket 150 is positioned facing either the first end 121 or the second end 122. This design ensures that even after the left and right lifting table legs are rotated 180 degrees to interchange positions, the space on both sides of the lifting column remains unchanged. This prevents the lifting column from being misaligned on the foot, which could lead to a decrease in the space in front of the lifting column due to the interchange of the two lifting table legs, thus avoiding interference with the user's legs.

[0049] It is understood that in other embodiments of this utility model, the distance between the first end of the foot and the lifting column may not be equal to the distance between the second end of the foot and the lifting column.

[0050] It is understood that in other embodiments of this utility model, the outlet is a through hole, and one end of the adapter cable passes through the outlet and is integrally connected to the cable. This design simplifies the connection structure between the adapter cable and the cable, thereby reducing the number of parts and further reducing manufacturing costs.

[0051] It is understood that in other embodiments of this utility model, the sleeve assembly is inverted so that the outer tube passes through the mounting port and is inserted into the decorative cover, the outlet is located at the bottom of the outer tube, and the inner tube is fixedly connected to the bottom box.

[0052] Example 2

[0053] like Figures 4 to 6 As shown, this embodiment also discloses an electric height-adjustable desk, including a tabletop 200 and first and second height-adjustable table legs 300 spaced apart along the left and right directions of the tabletop 200. The first height-adjustable table leg is the height-adjustable table leg 100 described in the above technical solution. The sleeve assembly also includes a second tube, with an outer tube 114 forming the second tube. The second tube is detachably connected to the tabletop 200 through a base box 160. The feet 120 extend along the front and rear directions of the tabletop 200. The difference between the second and first height-adjustable table legs is that only the cable, adapter cable, and first socket are omitted, and no cable outlet is required on the first tube; all other structures are the same. Figure 2 and 4 As shown, the first lifting table leg is in the forward installation position. At this time, when the lower end of the first tube 112 passes through the installation port 131 in the forward direction, the cable outlet 1120 is set to face backward and towards the first socket 150. The adapter cable 140 can be wrapped around the outside of the first tube 112 and then electrically connected to the first socket 150 to realize the storage of the excess length of the adapter cable 140.

[0054] During the assembly of the electric height-adjustable desk, if the lifting column of the first height-adjustable desk leg is found to be... Figure 5 As shown, it is installed in reverse on the right side of the tabletop (e.g.) Figure 5 As shown, with the cable outlet 1120 facing forward, the first lifting table leg is in the reverse installation position. When assembling the foot assembly, the foot assembly needs to be rotated so that the first socket 150 faces backward. Then, the first plug 141 of the adapter cable 140 is electrically connected to the second socket 171 facing forward. The other end is wrapped around to the back of the lifting column 110 and connected to the first socket 150. Then, the first tube 112 is tilted and inserted into the installation port 131 so that the first plug 141 enters the decorative cover 130. Then, the first tube 112 is straightened. Finally, the first tube 112 and the foot 120 are connected by screws.

[0055] If, during the assembly of the electric height-adjustable desk, the first lifting column 110 and the base assembly of the first height-adjustable desk leg are assembled first, and then the first socket 150 is found to be facing the user side after the first height-adjustable desk leg is assembled onto the tabletop 200, then it is only necessary to remove the base assembly from the lifting column 110, rotate the removed base assembly 180 degrees so that the first socket 150 faces backward, and then reassemble the base assembly with the lifting column 110. The specific assembly process can be referred to the above description and will not be detailed here.

[0056] Therefore, when the first lifting table leg is swapped with the second lifting table leg by approximately 300 degrees from its original installation position (e.g.) Figure 4 Switch to the reverse installation position (e.g., with the cable outlet facing backward). Figure 5Even with the cable outlet facing forward, the foot assembly of the first socket 150, which faces backward, can still be adapted to the reverse-installed lifting column. In this case, simply wrap the end of the adapter cable 140 connected to the first socket 150 around to the back of the lifting column to connect it to the first socket 150. This eliminates the need to disassemble and reassemble the lifting column, making assembly easier for users. Finally, since the first lifting table leg can be swapped with the second lifting table leg 300, the direction of the foot assembly can be adjusted to ensure that the first socket 150 faces backward. Therefore, users can adjust the position of the lifting table leg with cable according to different usage scenarios to bring the first socket 150 closer to the external power source, thereby improving the user experience.

[0057] 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.
