Description

Technical Field

[0001] This utility model belongs to the field of furniture, specifically relating to a height-adjustable table that is easy to maintain. Background Technology

[0002] As living standards improve, people's needs for tables are becoming more and more diverse, among which height-adjustable desks are becoming increasingly popular.

[0003] A height-adjustable desk typically consists of a tabletop, a crossbeam mounted at the bottom of the tabletop, and a lifting column that raises and lowers the crossbeam and tabletop. A controller that controls the lifting column's movement is concealed within the crossbeam. The tabletop fits over the cavity in the crossbeam that houses the controller and is secured to the crossbeam with multiple screws. This design has the following drawbacks: when the controller malfunctions or is damaged, maintenance personnel need to remove multiple screws to detach the heavy tabletop from the crossbeam to access the controller for repair. After repair, the tabletop and crossbeam must be reinstalled, resulting in a significant workload that is difficult for a single person to complete. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lifting table that is easy to maintain, so as to solve the problem of difficult maintenance of the controller of the lifting column.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a height-adjustable table that is easy to maintain, comprising a tabletop, a crossbeam located at the bottom of the tabletop, and height-adjustable columns installed at both ends of the crossbeam. The crossbeam has a receiving groove with an opening facing the tabletop, and a controller for controlling the height adjustment of the height-adjustable columns is installed in the receiving groove. An inspection port is also provided at the bottom of the crossbeam, extending longitudinally through the crossbeam to allow the receiving groove to communicate with the outside through the inspection port. This technical solution has the following technical effects:

[0006] This invention features a recessed slot on the crossbeam, within which the controller controlling the lifting column's movement is placed, concealing the controller and preventing it from being exposed. This enhances the aesthetics and prevents users from bumping into the controller while using the height-adjustable table. Because the crossbeam is fixed to the tabletop with locking screws, an inspection port is provided at the bottom of the crossbeam. This allows maintenance personnel to easily access and inspect the controller in case of malfunction or damage, or to remove it for repair without disassembling and reassembling the crossbeam and tabletop. This significantly reduces the difficulty of controller maintenance, thereby simplifying the overall maintenance of the height-adjustable table, allowing a single maintenance worker to complete the task.

[0007] In the aforementioned easily maintainable lifting table, the bottom of the crossbeam is equipped with a cover plate that fits over the access port. The cover plate is detachably connected to the crossbeam. When the controller needs maintenance, the maintenance personnel can remove the cover plate. After maintenance, the cover plate can be replaced to prevent large amounts of dust or liquid from entering the crossbeam's receiving groove through the access port, thus avoiding water or dust accumulation in the receiving groove and preventing it from affecting the controller, thereby extending the controller's service life.

[0008] In the aforementioned easy-to-maintain lifting table, the cover plate includes a plate body. One end of the plate body is locked to a crossbeam via a clamping assembly, and the other end of the plate body is provided with an inclined stop edge. When the cover plate is closed on the access port, the stop edge extends into the receiving groove, and the lower surface of the stop edge abuts against the crossbeam. When the cover plate is closed on the access port, the inclined stop edge extends into the receiving groove, and the lower surface of the stop edge abuts against the crossbeam on the side of the access port. That is, the crossbeam, through the clamping assembly, vertically limits one end of the plate body, and the crossbeam, by abutting against the stop edge, vertically limits the other end of the plate body, preventing the plate body from freely detaching from the access port. This facilitates the installation and disassembly of the plate body while making the installation of the plate body more stable and reliable.

[0009] In the aforementioned easy-to-maintain lifting table, a stop plate is also provided at the end of the plate with a stop edge. When the cover plate is closed on the access port, the stop plate extends horizontally and abuts against the bottom surface of the crossbeam. This further limits the vertical movement of the end of the plate with the stop edge. When the end of the cover plate with the stop plate and stop edge is installed in place, the stop plate abuts against the bottom surface of the crossbeam to stop the end of the cover plate, preventing the cover plate from moving further into the receiving groove. At the same time, the stop edge abuts against the crossbeam to prevent the end of the cover plate from moving freely downward from the access port to detach from the access port, facilitating the installation and removal of the cover plate.

[0010] In the aforementioned easy-to-maintain lifting table, two stop plates are provided, located on either side of the stop edge and offset from it. By offsetting the stop edge and the stop plates, the manufacturing difficulty of the cover plate can be reduced. At the same time, the stop plates and the stop edge fit more tightly with the crossbeam on the side of the inspection port, resulting in better limiting effect.

[0011] In the aforementioned easy-to-maintain lifting table, the stop edge is formed by bending the end of the plate, and the angle between the stop edge and the plate is α, satisfying 30°≤α≤60°. By setting the angle between the stop edge and the plate within the range of 30° to 60°, when the plate horizontally covers the inspection opening, the stop edge will not affect its contact and limiting with the crossbeam due to an excessively large angle, nor will it affect the rotation during cover plate disassembly due to an excessively small angle. This avoids difficulty in disassembling the cover plate due to an excessively small rotation angle, reducing the difficulty of disassembling and assembling the cover plate.

[0012] In the aforementioned easily maintainable lifting table, the locking assembly includes a positioning component fixed in a receiving groove and a locking component fixed on the plate. The locking component has a locking groove, and the positioning component includes a base with a positioning groove, a ball bearing, and a spring within the positioning groove. The spring pushes the ball bearing partially into the locking groove, causing the locking component to engage with the positioning component. When the cover plate closes the access port, the ball bearing, pushed by the spring, partially extends into the locking groove, causing the locking component to engage with the positioning component. The structure of the spring and ball bearing ensures a good locking effect between the positioning component and the locking component. Furthermore, maintenance personnel can easily separate the positioning component and the locking component with force, making operation simple and convenient without damaging either component and extending their service life.

[0013] In the aforementioned easy-to-maintain lifting table, the panel is provided with an operating hole for inserting fingers. The operating hole is located on the side of the panel near the locking assembly. When it is necessary to remove the cover plate, the user or maintenance personnel can insert their fingers into the operating hole and pull the cover plate downwards by bending their fingers. This facilitates the application of force, and the force applied to the cover plate can disengage the locking and positioning components. Positioning the operating hole close to the locking assembly makes it even easier to apply force.

[0014] In the aforementioned easy-to-maintain lifting table, the two sides of the cover plate are bent to form guide edges perpendicular to the cover plate, and the two sides of the access port are bent into the receiving groove to form sealing edges. When the cover plate is closed on the access port, the guide edges extend into the receiving groove and abut against the side of the sealing edges. During the process of the cover plate closing onto the access port, the guide edges can guide and align the cover plate. When the cover plate is closed on the access port, the guide edges extend into the receiving groove, and the side of the guide edges abuts against the side of the sealing edges to seal the gap between the cover plate and the access port, preventing external dust or liquid from entering the receiving groove through the gap between the cover plate and the access port, resulting in a good sealing effect.

[0015] In the aforementioned easy-to-maintain height-adjustable table, the access port is located on one side of the controller, and the projection of the controller on the horizontal plane does not coincide with the projection of the access port on the horizontal plane. By offsetting the access port from the controller, dust entering the receiving tank through the access port can be prevented from accumulating directly on the controller, and liquid entering the receiving tank through the access port can be prevented from directly soaking and damaging the controller.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0034] This utility model proposes a height-adjustable desk that is easy to maintain. It includes a tabletop, a crossbeam located at the bottom of the tabletop, and height-adjustable columns installed at both ends of the crossbeam. The crossbeam has a receiving groove with an opening facing the tabletop. A controller for controlling the height of the height-adjustable columns is installed in the receiving groove. An inspection port is also provided at the bottom of the crossbeam, extending longitudinally through the crossbeam to allow the receiving groove to communicate with the outside. This utility model conceals the controller by providing a receiving groove on the crossbeam and placing it inside, thus avoiding external exposure, improving aesthetics, and preventing users from bumping into the controller while using the desk. Because the crossbeam is fixed to the tabletop with locking screws, the inspection port at the bottom of the crossbeam allows maintenance personnel to easily access and repair the controller when it malfunctions or is damaged. This eliminates the need for disassembling and reassembling the crossbeam and tabletop, significantly reducing the difficulty of controller maintenance and consequently the overall maintenance of the height-adjustable desk, allowing a single maintenance worker to complete the task.

[0040] Example 1:

[0041] An easy-to-maintain height-adjustable desk, such as Figures 1 to 9 As shown, the device includes a tabletop 100, a crossbeam 200, and lifting columns 300. The crossbeam 200 is horizontally positioned at the bottom of the tabletop 100 and is locked to the tabletop 100 by locking screws. Vertically positioned lifting columns 300 are installed at both ends of the crossbeam 200 to support the crossbeam 200. A receiving groove 210 with an opening facing the tabletop 100 is formed on the crossbeam 200. A controller 400 is installed in the receiving groove 210. Preferably, the controller 400 is slidably attached to the crossbeam 200 and is hidden inside the crossbeam 200 to control the lifting of the lifting columns 300, thereby realizing the lifting of the tabletop 100. An inspection port 220 is also provided at the bottom of the crossbeam 200. The inspection port 220 is longitudinally positioned through the crossbeam 200 so that the receiving groove 210 can communicate with the outside through the inspection port 220.

[0042] This invention conceals the controller 400 by providing a receiving groove 210 on the crossbeam 200 and placing it inside the groove. This design improves the aesthetics of the device and prevents users from bumping into the controller 400 while using the height-adjustable table. Since the crossbeam 200 is fixed to the tabletop 100 with locking screws, an inspection port 220 is provided at the bottom of the crossbeam 200. This allows maintenance personnel to easily inspect or remove the controller 400 when it malfunctions or is damaged, eliminating the need for disassembly and reassembly of the crossbeam 200 and tabletop 100. This significantly reduces the difficulty of controller maintenance, thereby simplifying the overall maintenance of the height-adjustable table, which can be completed by a single maintenance worker.

[0043] like Figure 1 As shown, in order to prevent a large amount of dust or liquid from entering the receiving groove 210 of the crossbeam 200 through the inspection port 220 and becoming difficult to clean, this embodiment also provides a cover plate 500 at the bottom of the crossbeam 200 that covers the inspection port 220. The cover plate 500 is detachably connected to the crossbeam 200. When the controller 400 needs to be repaired, the maintenance personnel can remove the cover plate 500. After the controller 400 is repaired, the maintenance personnel can put the cover plate 500 back on the inspection port 220 to avoid water or dust accumulation in the receiving groove, thereby preventing water or dust accumulation in the receiving groove 210 from affecting the operation of the controller 400 and extending the service life of the controller 400.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the cover plate 500 includes a plate body 510. One end of the plate body 510 is locked to the crossbeam 200 by a clamping assembly 600. The other end of the plate body 510 is provided with a stop edge 520. The stop edge 520 is inclined, that is, the angle between the upper surface of the stop edge 520 and the top surface of the plate body 510 is less than 180 degrees. When the cover plate 500 is closed on the access port 220, the inclined stop edge 520 extends into the receiving groove 210, and the stop edge 520 is inclined. The lower surface of the stop 520 abuts against the crossbeam 200 on the side of the access port 220. That is, the crossbeam 200 limits one end of the plate 510 in the vertical direction through the clamping assembly 600, and the crossbeam 200 limits the other end of the plate 510 in the vertical direction by abutting against the stop 520, so as to prevent the plate 510 from freely detaching from the access port 220. This facilitates the installation and disassembly of the plate 510, and makes the installation of the plate 510 more stable and reliable.

[0045] To further limit the vertical movement of the end of the plate 510 with the stop edge 520, this embodiment also provides a stop piece 530 on the plate 510. The stop piece 530 is disposed at the end of the plate 510 and is parallel to the plate 510. Figure 3 As shown, when the cover plate 500 is closed over the access port 220, the stop plate 530 extends horizontally to the bottom of the crossbeam 200 on the side of the access port 220 and abuts against the bottom surface of the crossbeam 200; when the cover plate 500 is removed, as Figure 5 As shown, first, disengage one end of the plate 510 equipped with the clamping assembly 600 from the crossbeam 200. Then, rotate the plate 510 around the other end of the plate 510. The crossbeam 200 moves within the triangular space formed between the stop edge 520 and the stop piece 530, allowing the plate 510 to rotate at a certain angle. Then, move the plate 510 diagonally downwards to detach it from the inspection port 220 of the crossbeam 200. When installing the cover plate 500, first tilt the plate 510... The plate is placed diagonally below the access port 220, and the triangular space formed between the stop edge 520 and the stop piece 530 is aligned with the crossbeam 200 on the side of the access port 220, so that the crossbeam 200 on the side of the access port 220 is engaged between the stop edge 520 and the stop piece 530. Then, the other end of the plate 510 is rotated toward the access port 220 around the end of the stop piece 530 that abuts against the crossbeam 200 until the other end of the plate 510 is locked to the crossbeam 200 by the locking assembly 600. When one end of the cover plate 500, which is equipped with a stop plate 530 and a stop edge 520, is installed in place, the stop plate 530 abuts against the bottom surface of the crossbeam 200 to stop the end of the cover plate 500 and prevent the cover plate 500 from continuing to move into the receiving groove. At the same time, the stop edge 520 abuts against the crossbeam 200 to prevent the end of the cover plate 500 from moving freely downward from the access port 220 to disengage from the access port 220, thus facilitating the installation and removal of the cover plate 500.

[0046] like Figure 7 As shown, in this embodiment, there are two stop plates 530. The two stop plates 530 are located on both sides of the stop edge 520 and are staggered with the stop edge 520. By staggering the stop edge 520 and the stop plates 530, the manufacturing difficulty of the cover plate 500 can be reduced. At the same time, the stop plates 530 and the stop edge 520 fit more tightly with the crossbeam 200 on the side of the inspection port 220, and the limiting effect is better.

[0047] Guide edges 540 perpendicular to the cover plate 500 are formed by bending on both sides of the plate 510. Sealing edges 221 are formed by bending on both sides of the access port 220 into the receiving groove 210. During the process of the cover plate 500 closing onto the access port 220, the guide edges 540 can guide and align the cover plate 500. When the cover plate 500 is closed onto the access port 220, as... Figure 3As shown, the guide edge 540 extends into the receiving groove 210, and the side of the guide edge 540 abuts against the side of the sealing edge 221 to seal the gap between the cover plate 500 and the access port 220, preventing external dust or liquid from entering the receiving groove 210 through the gap between the cover plate 500 and the access port 220, thus achieving a good sealing effect.

[0048] In this embodiment, the stop edge 520 is preferably formed by bending the end of the plate 510, which is easy to process. Figure 8 As shown, the angle between the stop edge 520 and the plate 510 is specified as α, satisfying 30°≤α≤60°. By setting the angle between the stop edge 520 and the plate 510 within the range of 30° to 60°, when the plate 510 horizontally covers the inspection port 220, the stop edge 520 will not affect its contact limit with the crossbeam 200 due to an excessively large angle, nor will it affect the rotation of the cover plate 500 during disassembly due to an excessively small angle. This avoids the difficulty of disassembling the cover plate 500 due to an excessively small rotation angle, and reduces the difficulty of disassembling and assembling the cover plate 500.

[0049] like Figure 2 and Figure 9 As shown, the clamping assembly 600 includes a positioning member 610 and a locking member 620. The positioning member 610 is fixed in the receiving groove 210 by a locking screw and is located above the access port 220. The locking member 620 is fixed above one end of the plate 510 by a locking screw. A locking groove 621 is provided on the locking member 620. The positioning member 610 includes a base 611 fixed on the crossbeam 200. A horizontally extending positioning groove 612 is provided in the base 611. A ball 613 and a spring 614 are provided in the positioning groove 612. The diameter of the groove opening of the positioning groove 612 is smaller than the ball diameter of the ball 613 to prevent the ball 613 from disengaging from the positioning groove 612. In this preferred embodiment... Yes, the positioning groove 612 extends through the base 611, and two ball bearings 613 are provided. The two ends of the spring 614 abut against the two ball bearings 613 respectively, pushing the ball bearings 613 outward from the positioning groove 612. When the cover plate 500 closes the inspection port 220, the ball bearings 613 partially extend into the slot 621 under the push of the spring 614, so that the locking member 620 engages with the positioning member 610. The structure of the spring 614 and the ball bearings 613 provides a good locking effect between the positioning member 610 and the locking member 620. At the same time, maintenance personnel can easily separate the positioning member 610 and the locking member 620 with force, making the operation simple and convenient, without causing damage to either of them, and extending their service life. Of course, in another embodiment, the positioning groove may not extend through the base, and there may be only one ball bearing. The two ends of the spring abut against the inner wall of the positioning groove and the ball bearing respectively, pushing the ball bearing outward from the positioning groove.

[0050] To facilitate user removal of cover plate 500, such as Figure 6As shown, the plate 510 is provided with an operating hole 511 for inserting fingers. The operating hole 511 is located on the side of the plate 510 near the clamping assembly 600. When it is necessary to remove the cover plate 500, the user or maintenance personnel can insert their fingers into the operating hole 511 and pull the cover plate 500 downward by bending their fingers, which makes it easier to apply force. The force applied to the cover plate 500 can disengage the snap-fit ​​620 from the positioning member 610. Setting the operating hole 511 close to the clamping assembly 600 can save more effort.

[0051] like Figure 4 As shown, in this embodiment, the inspection port 220 is located on one side of the controller 400. The projection of the controller 400 on the horizontal plane does not coincide with the projection of the inspection port 220 on the horizontal plane. By offsetting the inspection port 220 from the controller 400, dust entering the receiving tank 210 through the inspection port 220 can be prevented from directly accumulating on the controller 400, and liquid entering the receiving tank 210 through the inspection port 220 can be prevented from directly soaking and damaging the controller 400.

[0052] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
