Technical Field
[0001] This utility model relates to the field of electric height-adjustable desks, and in particular to height-adjustable desk legs for electric height-adjustable desks and electric height-adjustable desks. Background Technology
[0002] Current electric height-adjustable desks on the market include a tabletop, two adjustable legs supporting the tabletop, and a controller. The adjustable legs consist of lifting columns and feet mounted at the base of the columns. The controller is electrically connected to the motors of the two lifting columns, supplying power to the motors and controlling their operation, thereby controlling the extension and retraction of the legs to raise and lower the tabletop. To allow the controller to connect to an external power source, existing controllers have exposed power cords that connect to an external power source to supply power. Because the power cord moves with the tabletop's movement, a portion of the cord hangs suspended below the tabletop. This can lead to situations where users pull on the power cord, causing it to disconnect from the external power source or even break.
[0003] To address the aforementioned technical issues, existing technologies incorporate a retractable cable within the sleeve assembly of one of the adjustable table legs. One end of the cable connects to a controller, while the other end connects to a power cord located outside the adjustable column via an outlet on the sleeve assembly. This power cord is connected to an external power source, and the outlet must be positioned on the side of the sleeve assembly facing away from the user to prevent the user's legs from snagging on the power cord or kicking the connection point. This necessitates careful attention to the position of the two adjustable table legs during assembly, ensuring the outlet on the sleeve assembly faces away from the user. If the two legs are swapped, the outlet will face the user, increasing the risk of the user's legs snagging on the power cord or kicking the connection point. In other words, the existing adjustable table leg structure requires assemblers to ensure correct leg placement, causing inconvenience and reducing the user experience. Utility Model Content
[0004] To address the shortcomings and deficiencies in the existing technology, this utility model provides a lifting table leg for an electric lifting table and an electric lifting table. By setting a protective cover, the connection end of the power cord and the outlet can be protected, preventing the user's legs from colliding with the outlet and the power cord end, which could cause a circuit break or even damage. It also facilitates assembly.
[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0006] The electric height-adjustable desk has a height-adjustable leg, which includes a height-adjustable column and a base installed at the bottom of the height-adjustable column. 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 connected to the base. One end of the first tube connected to the base has a cable outlet located outside the base. The cable is electrically connected to one end of an external power cord through the cable outlet. The height-adjustable desk also includes a protective cover. The cable outlet and part of the power cord are housed in the protective cover. The protective cover has a cable outlet hole through which the other end of the power cord passes out of the protective cover.
[0007] In the aforementioned electric height-adjustable desk legs, the protective cover includes a side wall surrounding the first tube, and the cable outlet and part of the power cord are housed between the side wall and the first tube.
[0008] In the aforementioned electric height-adjustable table legs, the protective cover includes a first half-shell and a second half-shell, which are separately machined and formed. The first half-shell and the second half-shell can be detachably connected to form the protective cover.
[0009] In the aforementioned electric height-adjustable table legs, the splicing surface of the first half-shell and the second half-shell extends along the length direction of the base.
[0010] In the aforementioned electric lifting table legs, the first half of the cover is provided with a first notch, and the second half of the cover is provided with a second notch. After the first half of the cover and the second half of the cover are spliced together, the first notch and the second notch cooperate to form the cable outlet hole.
[0011] In the aforementioned electric height-adjustable desk legs, the protective cover has a perforation, and the foot passes through the perforation.
[0012] In the aforementioned electric height-adjustable desk legs, the protective cover is set independently of the lifting column and supported on the top surface of the base. The protective cover is detachably connected to the lifting column and / or the base. The top of the protective cover is provided with a through hole for the first pipe to pass through.
[0013] In the aforementioned electric height-adjustable table legs, the cable outlet is an interface, the cable is electrically connected to the interface, and one end of the power cord is provided with a first plug that is plugged into the interface, the first plug being located inside a protective cover; or, the cable outlet is a through hole, and one end of the power cord passes through the cable outlet and is integrally connected to the cable.
[0014] 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 is 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 height-adjustable table leg is used to drive the tabletop to rise and fall.
[0015] In the aforementioned electric lifting table, the protective cover has a side wall surrounding the first tube, and the cable outlet hole is provided on the rear side of the side wall.
[0016] By adopting the above technical solution, this utility model has the following advantages:
[0017] 1. After the lifting table legs of this utility model are assembled, the cable outlet and the end connected to the external power cord are both housed within a protective cover. This provides physical protection for the connection between the cable outlet and the power cord, such as protection against kicks, dust, and liquid splashes. Even if the positions of the left and right lifting table legs are reversed, causing the cable outlet to face the user, the protective cover still protects the user-facing cable outlet and the end connected to the external power cord, preventing the user's legs from colliding with the cable outlet and power cord, which could cause a short circuit or even damage. In other words, when assembling the lifting table legs of this utility model... When installing the lifting legs on either the left or right side of the tabletop, the cable outlet and one end of the power cord are protected by the protective cover. During assembly, there is no need to pay attention to whether the lifting legs are installed on the left or right side of the tabletop, as long as they are close to the external power source. This simplifies assembly and improves the user experience. Finally, since the cable runs through the sleeve assembly axially and the cable outlet is located inside the protective cover, the cable inside the lifting column is not exposed. Only a portion of the external power cord is exposed. By storing the excess power cord inside the protective cover, the size of the exposed power cord is reduced, thus lowering the probability of the user's legs getting caught on the cord.
[0018] 2. The protective cover includes a side wall surrounding the first tube, with the cable outlet and part of the power cord housed between the side wall and the first tube. This design allows excess power cords to be stored inside the protective cover by wrapping around the outside of the lifting column, preventing the power cords from piling up disorderly inside the protective cover and breaking due to excessive bending angles. In addition, the wrapping method allows for adjustment of the power cord's exit direction, making it easier for the other end of the power cord to be led out through the outlet hole.
[0019] 3. The protective cover consists of a first half-shell and a second half-shell, which are machined separately. The first half-shell and the second half-shell can be detachably connected to form the protective cover. This design eliminates the need to change the shape of the existing base. By adapting the first half-shell and the second half-shell to the first pipe and the base, the protective cover can be added. At the same time, the protective cover can be independently assembled and disassembled. Without disassembling the lifting column and the base, the length of the power cord stored inside the protective cover can be adjusted by removing the protective cover.
[0020] 4. The splicing surface of the first and second half-shells extends along the length of the base. With this design, due to the large length of the base, if the splicing surface of the first and second half-shells extends along the width of the base while maintaining the same internal space of the protective cover, the first and second half-shells would need to be very large in the length direction of the base to avoid the protective cover occupying leg space. This would increase the depth of the first and second half-shells, thus increasing the manufacturing difficulty. This technical solution maximizes the length of the first and second half-shells while minimizing their width, thereby reducing the depth of the first and second half-shells and reducing their manufacturing difficulty.
[0021] 5. The first half of the cover has a first notch, and the second half of the cover has a second notch. After the first and second half of the cover are joined together, the first notch and the second notch cooperate to form a cable outlet hole. This design facilitates the processing of the first and second notches, thereby further reducing the processing difficulty of the first and second half of the cover.
[0022] 6. The protective cover is equipped with through holes, and the feet are designed to pass through these holes. This design allows for upper and lower limit positioning of the protective cover via the through holes, thereby improving the installation reliability of the protective cover.
[0023] 7. The outlet is an interface, and the cable is electrically connected to the interface. One end of the power cord has a first plug that plugs into the interface, and the first plug is located inside the protective cover. This design can protect the first plug by covering it with the protective cover, preventing the first plug from detaching from the interface due to the user's feet bumping into it. Alternatively, the outlet is a through hole, and one end of the power cord passes through the outlet and is connected to the cable as a whole. This design simplifies the connection structure of the power cord and the cable, and further reduces manufacturing costs.
[0024] 8. An electric height-adjustable desk, comprising 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-mentioned technical solution. The sleeve assembly further includes a second tube connected to the tabletop. The height-adjustable legs are used to drive the tabletop to rise and fall. This design, by adopting the height-adjustable legs of this utility model, eliminates the need for the assembler to pay attention to whether the height-adjustable legs are installed on the left or right side of the tabletop during assembly; they only need to be close to an external power source. This simplifies assembly and improves the user experience.
[0025] 9. The protective cover has a side wall surrounding the first tube, and a cable outlet hole is provided on the rear side of the side wall. With this design, even if the first lifting table leg is installed incorrectly and the cable outlet faces the user side, the other end of the power cord can be wound around the first tube and led out through the cable outlet hole. This reduces the requirements for the position of the first lifting table leg during assembly and improves assembly efficiency. In addition, the power cord can be led out towards the wall through the cable outlet hole to further reduce the risk of the user's legs getting caught on the power cord. Attached Figure Description

[0035] This utility model provides a height-adjustable table leg for an electric height-adjustable desk, including a height-adjustable column and a base installed at the bottom of the height-adjustable column. 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 connected to the base, and one end of the first tube connected to the base has a cable outlet located outside the base. The cable is electrically connected to one end of an external power cord through the cable outlet. The height-adjustable table leg also includes a protective cover, in which the cable outlet and part of the power cord are housed. The protective cover has a cable outlet hole, through which the other end of the power cord passes out of the protective cover.
[0036] After the lifting table legs of this invention are assembled, the cable outlet and the end where the external power cord connects to the cable outlet are both housed within a protective cover. This provides physical protection for the connection point, such as protection against kicks, dust, and liquid splashes. Even if the left and right lifting table legs are swapped, causing the cable outlet to face the user, the protective cover still protects the user-facing cable outlet and the end where the external power cord connects to the cable outlet, preventing the user's legs from colliding with the cable outlet and power cord, which could cause a short circuit or even damage. In other words, when assembling the lifting table legs of this invention… Regardless of whether it is installed on the left or right side of the tabletop, the cable outlet and one end of the power cord can be protected by the protective cover. During assembly, there is no need to pay attention to whether the lifting table leg is installed on the left or right side of the tabletop, as long as it is close to the external power source. This simplifies assembly and improves the user experience. Finally, since the cable runs through the sleeve assembly axially and the cable outlet is located inside the protective cover, the cable inside the lifting column is not exposed. Only part of the external power cord is exposed. By storing the excess power cord inside the protective cover, the size of the exposed power cord can be reduced, thereby reducing the probability of the user's legs getting caught on the cord.
[0037] 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.
[0038] Example 1
[0039] Combination Figures 1 to 3As shown, the electric height-adjustable table leg 100 of this utility model includes a height-adjustable column 110 and a foot 120 installed at the bottom of the height-adjustable column 110. 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 (not shown in the figure) axially passing through the sleeve assembly. The sleeve assembly includes a first tube 111 connected to the foot 120. One end of the first tube 111 connected to the foot 120 is provided with a cable outlet located outside the foot 120. The cable outlet is located above the top surface of the foot 120. The cable is connected to one end of an external power cord 130 through the cable outlet. The height-adjustable table leg 100 also includes a protective cover 140. The cable outlet and part of the power cord 130 are housed in the protective cover 140. The protective cover 140 is provided with a cable outlet hole 1401. The other end of the power cord 130 passes through the cable outlet hole 1401 and exits the protective cover 140.
[0040] After the lifting table legs 100 in this embodiment are assembled, the cable outlet and the end of the external power cord 130 connected to the cable outlet are both housed within the protective cover 140. This provides physical protection for the connection between the cable outlet and the power cord, such as protection against kicks, dust, and liquid splashes. Even if the positions of the left and right lifting table legs are reversed, causing the cable outlet to face the user, the protective cover 140 still protects the user-facing cable outlet and the end of the external power cord 130 connected to the cable outlet, preventing the user's legs from colliding with the cable outlet and the power cord, which could cause a short circuit or even damage. In other words, when the assembler assembles the lifting table legs in this embodiment, there is no risk of injury. Whether the leg is installed on the left or right side of the tabletop, both the cable outlet and one end of the power cord can be protected by the protective cover 140. During assembly, there is no need to pay attention to whether the lifting table leg is installed on the left or right side of the tabletop, as long as it is close to the external power source. This simplifies assembly and improves the user experience. Finally, since the cable runs through the sleeve assembly axially and the cable outlet is located inside the protective cover 140, the cable inside the lifting column 110 is not exposed. Only part of the external power cord 130 is exposed. By storing the excess power cord 130 inside the protective cover 140, the size of the exposed power cord 130 can be reduced, thereby reducing the probability of the user's legs getting caught on the cord.
[0041] In this embodiment, the specific structure of the lifting column 110 can be referenced from the existing technology CN221599451U. That is, the cable is spiral-shaped. When the lifting column 110 extends, the pitch of the cable increases to lengthen the whole structure. When the lifting column 110 shortens, the pitch of the cable decreases to retract the whole structure. Therefore, the cable 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 112, and an outer tube that are sequentially sleeved from the inside out. Unlike the prior art CN221599451U, the inner tube forms a first tube 111, and the outer tube forms a second tube 113. The first tube 111 is connected to the foot 120, and the second tube 113 is fixedly connected to the top motor box 150. The motor box is fixed to the tabletop, meaning the second tube 113 is connected to the tabletop via the motor box 150. The upper end of the cable is led out through the motor box 150 and connected to the controller. The bottom of the first tube 111 has the aforementioned cable outlet. An interface with a terminal block is connected. The terminal block is located in the first tube 111 and electrically connected to the lower end of the cable, thereby realizing the electrical connection between the cable and the interface. The first tube 111 is also equipped with an overload protection structure, which is electrically connected to the terminal block connected to the live wire. When the current exceeds the limit value, the overload protection structure will automatically trip and cut off the circuit to prevent the wire from being burned due to overload. This effectively reduces the occurrence of equipment damage and threats to personal safety caused by short circuits, protects the lifting column from damage by overload current, and ensures the safety of the product during use. In this embodiment, one end of the power cord 130 is equipped with a first plug 131. The first plug 131 is plugged into the interface to realize electrical connection. The first plug 131 is located inside the protective cover 140. This design allows the first plug 131 to be covered and protected by the protective cover 140, preventing the first plug 131 from being disengaged from the interface due to the user's legs bumping into it.
[0043] Preferably, in this embodiment, the protective cover 140 includes a sidewall surrounding the first tube 111, forming an annular cavity around the first tube 111 between the sidewall and the first tube 111. The outlet and part of the power cord 130 are housed in the annular cavity. This design allows excess power cord 130 to be stored inside the protective cover 140 by wrapping around the outside of the first tube 111, preventing the power cord 130 from accumulating disorderly inside the protective cover 140 and breaking due to excessive bending angle. In addition, the wrapping method can also adjust the outlet direction of the power cord 130, so that the other end of the power cord 130 can be led out in an orderly manner through the outlet hole 1401.
[0044] To enable independent assembly and disassembly of the protective cover 140, the protective cover 140 in this embodiment includes a first half-cover 141 and a second half-cover 142, which are separately machined. The first half-cover 141 and the second half-cover 142 are assembled into the protective cover 140 by means of detachable connection such as adhesive, plug-in, screw connection, or snap-fit. The top of the first half-cover 141 and the second half-cover 142 are respectively provided with a top notch 143. The two top notches 143 cooperate to form a through hole 1402 for the first tube 111 to pass through. This design allows for the independent assembly and disassembly of the first half-cover 141 and the second half-cover 142 through the cooperation of the top notch and the first tube 111. 42 is positioned along the extension direction of the splicing surfaces of the two parts to ensure accurate alignment of the first half-cover 141 and the second half-cover 142, thus facilitating subsequent connection between the two. Furthermore, there is no need to change the existing foot shape. By adapting the top notches of the first half-cover 141 and the second half-cover 142 to the shape of the first tube 111 and by adapting the two half-covers to the foot 120, the protective cover 140 can be added, and the protective cover 140 can be independently disassembled and assembled. This allows for adjustment of the length of the power cord 130 stored inside the protective cover 140 without disassembling the lifting column 110 and the foot 120. Preferably, the first half-cover 141 and the second half-cover 142 have identical structures to avoid differentiation by the assembler and further facilitate assembly.
[0045] In this embodiment, the splicing surface of the first half-shell 141 and the second half-shell 142 extends along the length direction of the base 120 or along the width direction of the base 120. Preferably, the splicing surface of the first half-shell 141 and the second half-shell 142 extends along the length direction of the base 120. With this design, since the length of the foot 120 is relatively large, and given the same internal space of the protective cover 140, if the splicing surface of the first half-cover 141 and the second half-cover 142 extends along the width direction of the foot 120, in order to avoid the protective cover 140 occupying leg space, the dimensions of the first half-cover 141 and the second half-cover 142 in the length direction of the foot 120 need to be very large. This would increase the depth of the first half-cover 141 and the second half-cover 142, thereby increasing the processing difficulty of the first half-cover 141 and the second half-cover 142. However, by extending the splicing surface of the first half-cover 141 and the second half-cover 142 along the length direction of the foot 120, the dimensions of the first half-cover 141 and the second half-cover 142 in the length direction of the foot 120 can be maximized, while the dimensions in the width direction of the foot 120 can be minimized. This reduces the depth of the first half-cover 141 and the second half-cover 142, thereby reducing the processing difficulty of the first half-cover 141 and the second half-cover 142.
[0046] To form the cable outlet 1401, the first half-cover 141 in this embodiment has a first notch 144, and the second half-cover 142 has a second notch 145. After the first half-cover 141 and the second half-cover 142 are joined together, the first notch 144 and the second notch 145 cooperate to form the cable outlet 1401. This design facilitates the processing of the first notch 144 and the second notch 145, thereby further reducing the processing difficulty of the first half-cover 141 and the second half-cover 142.
[0047] It is understood that in other embodiments of this utility model, an independent cable outlet hole may also be provided on the first half-shell or the half-shell.
[0048] To further improve the installation reliability of the protective cover 140, in this embodiment, the bottom surfaces of the first half-cover 141 and the second half-cover 142 are lower than the bottom surface of the foot 120. The front and rear end faces of the first half-cover 141 and the second half-cover 142 are respectively provided with bottom notches 146 that open towards each other. The bottom notches 146 on the front end faces of the first half-cover 141 and the second half-cover 142 cooperate to form the front end of the through hole 1403, and the bottom notches 146 on the rear end faces of the first half-cover 141 and the second half-cover 142 cooperate to form the rear end of the through hole 1403. The foot 120 is set through the through hole 1403, that is, the first half-cover 141 and the second half-cover 142 are held on the foot 120. With this design, the upper and lower limits of the protective cover 140 can be achieved by the foot 120 passing through the through hole 1403, thereby improving the installation reliability of the protective cover 140.
[0049] It is understood that in other embodiments of this utility model, the bottom surfaces of the first half-shell and the second half-shell are supported on the top surface of the foot, and the protective cover is detachably connected to the lifting column and / or the foot by means of screws or snap-fit.
[0050] It is understood that in other embodiments of this utility model, the outlet is a through hole, and one end of the power cord passes through the outlet and is integrally connected with the cable. This design simplifies the connection structure of the power cord and the cable, 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 forms the first tube, the outlet is located at the bottom of the outer tube, and the inner tube is fixedly connected to the motor box.
[0052] Example 2
[0053] Compared with Embodiment 1, the difference in this embodiment is that the protective cover is an integral part that is independent of the lifting column and the foot. The protective cover is located on the side of the first tube with the cable outlet, and one side of the protective cover abuts against the side of the first tube with the cable outlet. The bottom surface of the protective cover is supported on the top surface of the foot. At this time, the top of the protective cover does not have a through hole, but the side facing the first tube needs to have a through hole for the first plug to pass through. The protective cover is detachably connected to the lifting column and / or the foot by means of screws or snap-fit. At this time, some power cords can be stored in the protective cover by stacking.
[0054] Example 3
[0055] Combination Figure 4 and Figure 5 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 left and right directions refer to the position on the user's left when using the electric height-adjustable desk; the left leg is the one on the user's left, and the right leg is the one on the user's right. The first height-adjustable table leg is the height-adjustable table leg 100 described in Embodiment 1 or 2. The first foot 120 extends along the front-back direction of the tabletop 200. The motor box 150 extends along the left and right directions of the tabletop and connects to the height-adjustable column 110 to form an inverted L-shaped structure. With this design, by adopting the height-adjustable table legs described in Embodiment 1, the assembler does not need to pay attention to whether the first height-adjustable table leg is installed on the left or right side of the tabletop 200 during assembly; as long as it is close to the external power source, assembly is convenient and the user experience is improved.
[0056] Preferably, the protective cover 140 in this embodiment adopts the protective cover of Embodiment 1, that is, the protective cover 140 has a side wall surrounding the first tube 111, so that an annular cavity surrounding the first tube 111 is formed between the protective cover 140 and the first tube 111. The excess power cord 130 is stored in the protective cover 140 by wrapping around the outside of the first tube 111. The rear side of the side wall is provided with the aforementioned cable outlet hole 1401. With this design, when the first lifting table leg is in accordance with... Figure 4 and Figure 5 When installing in the forward orientation (the first lifting leg is on the left side of the tabletop, while the first lifting leg is on the right side), the cable outlet 1401 faces backward—that is, towards the side away from the user. The power cord 130 can pass through the cable outlet 1401 and be directly led out to the power supply on the wall. After assembly, it should be installed as follows: Figure 6 and Figure 7When the first lifting table leg is installed in reverse (i.e., when the first lifting table leg is on the right side of the tabletop, it is a forward installation, and when the first lifting table leg is on the left side of the tabletop, it is a reverse installation), the cable outlet 1401 faces forward—that is, towards the user side. By wrapping the other end of the power cord around the back of the first tube 111 and ensuring that the cable outlet 1401 is behind the protective cover 140 after installation, the other end of the power cord can be led out through the cable outlet 1401 and then outward. This reduces the requirements for the position of the first lifting table leg during assembly and improves assembly efficiency. In addition, the power cord 130 can also be led out towards the wall through the cable outlet 1401 to further reduce the risk of the user's legs getting caught on the power cord 130.
[0057] Finally, the structure of the second lifting table leg 300 in this embodiment differs from that of the first lifting table leg only in that it does not have internal cables and external power cords. The rest of the structure is the same as that of the first lifting table leg, and will not be described in detail here. With this design, there is no need to distinguish between the two feet during assembly, thereby reducing the difficulty for the assembler.
[0058] It is understood that in other embodiments of this utility model, the feet of the second lifting table leg may adopt an existing straight foot structure.
[0059] 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.
