Description
Technical Field
[0001] This utility model relates to the field of furniture technology, and in particular to a height-adjustable table. Background Technology
[0002] Tables, as commonly used furniture, mainly consist of a tabletop and legs that support the tabletop. Currently, there are two main types on the market: height-adjustable and non-height-adjustable. Height-adjustable tables generally use electric push rods to drive the height adjustment, which has a relatively high production cost, and electronic components are more prone to damage than mechanical components. There is a lack of simple and practical height-adjustable tables. Utility Model Content
[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a height-adjustable desk that solves the problems of relatively high production cost and poor stability of existing height-adjustable desks.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a height-adjustable table, including a tabletop, a first leg and a second leg supporting the tabletop, the first leg and the second leg being hinged together at the middle, a first sliding groove being provided on the right side of the tabletop, the upper end of the first leg being hinged to the left side of the tabletop, and the upper end of the second leg being slidably disposed in the first sliding groove, so that when the first leg and the second leg rotate relative to each other, the height-adjustable table can switch between a raised state and a lowered state. Elastic locking fasteners are provided at both ends of the first sliding groove, which are used to engage with the second leg when the second leg slides into position in the first sliding groove, thereby maintaining the height-adjustable table in either a raised or lowered state. An unlocking component is also provided on the height-adjustable table, which is used to move the elastic locking fasteners to release the elastic locking fasteners from engaging with the second leg.
[0005] Furthermore, the elastic locking component includes a rotatable latch located at the bottom of the desktop and an elastic reset component for resetting the latch after rotation. The latch includes a guide ramp and a slot that engages with the second leg. The guide ramp guides the second leg into the slot after it slides into place.
[0006] By adopting the above technical solution, through the guide ramp and slot design of the buckle, when the second leg slides to the end of the slide groove, the guide ramp automatically guides the second leg into the slot, thereby locking the buckle onto the second leg to maintain the raised or lowered state of the lifting table. The elastic reset component can force the buckle to reset and lock, so that after the second leg slides and abuts against the buckle to enter the slot position, it drives the buckle to reset, thus achieving the engagement of the slot and the second leg.
[0007] Furthermore, the unlocking mechanism includes a rotating handle located on the side of the desktop, with the rotating handle and the latch connected by a connecting rope.
[0008] By adopting the above technical solution, rotating the handle can simultaneously release the latches on both sides of the slide groove through the connecting rope, allowing for one-handed operation and simplifying the unlocking process.
[0009] Furthermore, the elastic reset component includes an elastic telescopic component located on the side of the buckle, with one end of the elastic telescopic component fixed to the tabletop and the other end elastically abutting against the side of the buckle; or, the elastic reset component includes a torsion spring, with the buckle rotatably connected to the tabletop via a pivot, and the two ends of the torsion spring loaded on the tabletop and the buckle respectively, for reset after the buckle rotates.
[0010] By adopting the above technical solutions, the buckle can be rotated and reset by side-pressing the buckle with an elastic telescopic component, or the buckle can be reset after rotation by a rotating shaft and a torsion spring. Both methods have the advantages of simple structure and convenient maintenance.
[0011] Furthermore, the elastic telescopic component includes a spring seat mounted on the tabletop and a spring installed inside the spring seat, with one end of the spring extending out of the spring seat and elastically resisting the snap fastener.
[0012] By adopting the above technical solution, the telescopic structure composed of the spring seat and the spring directly pushes the side of the buckle, the direction of the elastic force is controllable, it can adapt to different installation space requirements, and it is easy to maintain and replace.
[0013] Furthermore, both the first and second tripods include a connecting rod and crossbars at both ends of the connecting rod. Both ends of the crossbars on the second tripod are provided with sliding rods, which are slidably adapted to the first sliding groove and are engaged with the elastic locking fastener.
[0014] By adopting the above technical solution, the two ends of the crossbar of the second tripod are equipped with sliding rods, and the sliding rods are adapted to slide with the first sliding groove. The double sliding rod design distributes the force and avoids single-point wear. The end of the sliding rod is engaged with the slot, which facilitates the cooperation between the buckle and the sliding rod.
[0015] Furthermore, a damping telescopic element is provided between the first and second tripods to allow for slow deployment when they rotate relative to each other.
[0016] By adopting the above technical solution, a damping telescopic component is added between the first and second legs to provide buffer resistance when the two rotate relative to each other, reduce the lifting speed, prevent the table from rising and falling suddenly, and ensure operational safety and stability.
[0017] Furthermore, an installation pad is provided on the inner bottom of the desktop, and the first slide, buckle, and elastic locking fastener are installed on the installation pad accordingly.
[0018] By adopting the above technical solution, a metal mounting plate is set on the inner side of the bottom of the desktop, and the first slide, buckle and elastic locking component are integrated and fixed on the plate, which improves the local structural strength and prevents the desktop from deforming due to the force of the locking area; at the same time, it simplifies the assembly process and reduces production costs.
[0019] Furthermore, the height-adjustable desk also includes a telescopic frame that houses the first and second legs. The telescopic frame includes a perimeter frame and an inner frame. One end of the inner frame is slidably disposed within the perimeter frame, and the other end is connected to the desktop. The lower end of the first leg is hinged to the perimeter frame, and the lower end of the second leg is slidably disposed on the perimeter frame.
[0020] By adopting the above technical solution and adding a telescopic frame, the entire first and second tripods can be stored and protected, while also improving aesthetics.
[0021] Furthermore, the surface of the frame is provided with a second mounting hole corresponding to the first tripod and a second sliding groove to accommodate the sliding of the second tripod.
[0022] By adopting the above technical solution, hinge points corresponding to the first leg are set on the surface of the frame to ensure that the force is uniform when the first leg rotates; the second slide groove slides with the lower end of the second leg to limit the sliding trajectory, prevent the second leg from deviating or falling out, and improve the guiding accuracy of the lifting process.
[0023] Compared with the prior art, the advantages of this utility model are:
[0024] 1. In this utility model, by setting a first sliding groove on the desktop and hinged the middle of the first leg and the second leg, the upper end of the first leg is hinged to the desktop, and the upper end of the second leg is slidably connected to the first sliding groove. Thus, during the relative rotation of the first leg and the second leg, the height of the height-adjustable table can be adjusted, allowing it to switch between raised and lowered states. At the same time, the elastic locking fasteners at both ends of the first sliding groove lock the second leg after it slides into place within the groove, which can restrict the relative rotation of the first leg and the second leg to maintain the raised or lowered state of the height-adjustable table. This effectively improves the structural stability of the entire table when it is raised or lowered, prevents the table from being accidentally unfolded when it is lowered, and effectively improves the safety of the product.
[0025] 2. In this utility model, the first leg and the second leg are cross-hinged in the middle, and the upper end of the second leg slides in the first groove, forming a stable cross-link lifting structure. When the two legs rotate relative to each other, the first groove restricts the movement trajectory of the second leg, ensuring that the desktop always remains horizontally raised and lowered, thus improving the stability of the table when it is raised and lowered. At the same time, the lifting structure is relatively simple, without complex electronic components, and the product cost is relatively low. Attached Figure Description

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0042] Reference Figure 1The height-adjustable desk includes a desktop 1, a first leg 2 and a second leg 3 supporting the desktop 1. The first leg 2 and the second leg 3 are hinged in the middle to form an "X"-shaped height-adjustable structure. A first slide groove 61 is provided on the right side of the desktop 1. The upper end of the first leg 2 is hinged to the left side of the desktop 1. The upper end of the second leg 3 is slidably disposed in the first slide groove 61 so that the height-adjustable desk can switch between a raised and a lowered state when the first leg 2 and the second leg 3 rotate relative to each other. The two ends of the first slide groove 61 are provided with elastic locking fasteners 5. The elastic locking fasteners 5 are used to engage with the second leg 3 when the second leg 3 slides into the first slide groove 61 to maintain the raised or lowered state of the height-adjustable desk. The height-adjustable desk is also provided with an unlocking component, which is used to move the elastic locking fasteners 5 to release the locking of the elastic locking fasteners 5 onto the second leg 3.
[0043] In this embodiment, the first leg 2 and the second leg 3 have the same structure, both including a connecting rod and a crossbar at both ends of the connecting rod. Preferably, there are two connecting rods, which are arranged in parallel. The crossbar is located at both ends of the connecting rod and connects the two connecting rods, so that the connecting rod and the crossbar are arranged perpendicularly. The connecting rods on the first leg 2 and the second leg 3 are hinged at the middle position so that when they rotate relative to each other, they can drive the tabletop 1 to rise or fall.
[0044] For ease of description, the connecting rod and crossbar on the first tripod 2 are referred to as the first connecting rod 21 and the first crossbar 22, respectively, and the corresponding ones on the second tripod 3 are referred to as the second connecting rod 31 and the second crossbar 32, respectively. The end closer to the tabletop 12 is referred to as the upper end, and the end farther from the tabletop 12 is referred to as the lower end.
[0045] Reference Figure 1 In this embodiment, the desktop 1 preferably adopts a rectangular structure. Taking a cuboid as an example, it includes a frame 11 and a tabletop 12 laid on the frame 11. The two ends of the first crossbar 22 and the two ends of the second crossbar 32 are respectively connected to the inner side of the frame 11. Specifically, the bottom front and rear sides of the frame 11 are provided with first mounting holes 110, and the two ends of the first crossbar 22 are respectively provided with hinge pieces 322. The hinge pieces 322 and the first mounting holes 110 are rotatably connected by a connecting shaft. The bottom front and rear sides of the frame 11 are provided with the first sliding groove 61 along its length direction, and the two ends of the second support rod are correspondingly slidably disposed in the first sliding groove 61.
[0046] In this embodiment, refer to Figure 2The elastic locking element 5 includes a buckle 51 rotatably disposed inside the frame 11 and an elastic reset element for the buckle 51 to reset after rotation. The buckle 51 includes a guide slope 511 and a groove 510 that engages with the second leg 3. The buckle 51 is L-shaped in overall structure, with the groove 510 located at the inner bend of the buckle 51. A pivot 512 passes through the adjacent position of the groove 510, rotatably connecting the buckle 51 to the frame 11. The guide slope 511 is located at the end of the buckle 51 facing the second crossbar 32. When the second crossbar 32 slides in the first slide groove 61 to press the guide slope 511, it abuts the buckle 51 to rotate around the pivot 512. (During the rotation of the buckle 51, the elastic reset member is compressed.) This allows the second crossbar 32 to slide into place in the first slide groove 61, disengage from the guide slope 511, and enter the slot 510. At this time, the elastic reset member is reset and abuts the buckle 51 to reset, completing the engagement between the slot 510 and the second crossbar 32. This achieves the locking of the rotation state between the second leg 3 and the first leg 2, so as to maintain the raised or lowered state of the lifting table.
[0047] In this embodiment, refer to Figure 1 In order to facilitate the sliding of the second crossbar 32 in the first slide groove 61 and to facilitate the engagement between the second crossbar 32 and the slot 510, slide bars 321 with a diameter smaller than that of the second crossbar 32 can be set at both ends of the second crossbar 32. By using the smaller diameter slide bars 321 to cooperate with the first slide groove 61 and the buckle 51, the volume of the first slide groove 61 and the buckle 51 can also be optimized.
[0048] In this embodiment, refer to Figure 2 In order to improve the structural strength of the connection between the frame 11 and the slide bar 321, a mounting plate 6 is provided on the inner side of the frame 11. The corresponding buckles and slide grooves are provided on the mounting plate 6. The mounting plate 6 can be a metal plate to increase its wear resistance.
[0049] Based on the above embodiments, to limit the rotation angle of the buckle 51, a limiting post 62 can be provided on the outside of the buckle 51 to limit the rotation angle of the buckle 51.
[0050] Based on the above embodiments, referring to Figure 4 As one embodiment of the elastic reset component, the elastic reset component can be an elastic telescopic component provided on the side of the buckle 51 near the desktop 1. The elastic telescopic component includes a spring seat 52 provided on the side of the mounting pad 6. The end of the spring seat 52 facing the buckle 51 has a blind hole, and a spring 53 is installed in the blind hole. The telescopic end of the spring 53 abuts against the buckle 51. When the buckle 51 is lifted up under the pressure of the slide rod 321, the spring 53 is compressed. When the slide rod 321 enters the slot 510 position, the spring 53 resets and presses the buckle 51 to reset, thereby realizing the buckle 51 and the slide rod 321 to lock together.
[0051] As another embodiment of the elastic reset component (without drawings), the reset of the buckle 51 can rely on a torsion spring. That is, when the buckle 51 is rotatably connected to the mounting pad 6 through the rotating shaft 512, a torsion spring can be sleeved on the outside of the rotating shaft 512, and the two ends of the torsion spring can be connected to the mounting pad 6 and the buckle 51 respectively, so that the buckle 51 can be reset after rotation by the elastic torque of the torsion spring.
[0052] Based on the above embodiments, the location of the elastic reset member may also be other locations outside the buckle 51. The elastic reset member may also be a compression spring, a tension spring, an elastic band, or other elastic structures, which will not be described in detail here.
[0053] Based on the above embodiments, referring to Figure 3 and 4 The unlocking component 7 includes a rotating handle 71 mounted on the frame 11 or the tabletop 12. For example, the rotating handle 71 is hinged to the frame 11. The frame 11 is provided with a base 111, and the middle part of the rotating handle 71 is rotatably mounted on the base 111. One end of the rotating handle 71 is connected to a section of the buckle 51 via a connecting rope 72. When it is necessary to release the buckle 51 from the slide bar 321, the rotating handle 71 can be turned, which in turn pulls the buckle 51 to rotate via the connecting rope 72. After the buckle 51 rotates, the slot 510 is unlocked from the slide bar 321. At this time, the second crossbar 32 can slide within the first slide groove 61 via the slide bar 321 to adjust the height of the lifting table.
[0054] Furthermore, to facilitate the reset of the rotating handle 71 after it has been turned, a corresponding elastic reset element can be provided between the rotating handle 71 and the base 111, similar to the buckle 51 and the mounting pad 6 mentioned above, so as to facilitate the reset of the rotating handle 71 after it has been turned. For example, a torsion spring can be provided between the rotating handle 71 and the base 111, etc., which will not be elaborated here.
[0055] Based on the above embodiments, in order to avoid exposing the entire first tripod 2 and second tripod 3, refer to... Figure 5 and 6The height-adjustable desk also includes a telescopic frame. Specifically, the telescopic frame includes an outer shell 81 and an inner shell 82. The lower end of the inner shell 82 is slidably disposed inside the outer shell 81 so that it can move relative to the outer shell 81. The upper end of the inner shell 82 is connected to the desktop 1. The two ends of the first crossbar 22 at the lower end of the first connecting rod 21 are respectively rotatably connected to the front and rear sides of the outer shell 81 near the left end. The two ends of the second crossbar 32 at the lower end of the second connecting rod 31 are correspondingly slidably connected to the front and rear sides of the outer shell 81 near the right end. The outer shell 81 is provided with a second sliding groove 810 corresponding to the position of the second crossbar 32 so that the second crossbar 32 can slide relative to the outer shell 81. The outer shell 81 is provided with a second mounting hole 811 corresponding to the position of the first crossbar 22 at the lower end of the first connecting rod 21 so that the first crossbar 22 can be rotatably connected to the outer shell 81. Thus, during the relative raising and lowering of the first leg 2 and the second leg 3, the inner shell 82 can be driven to extend and retract relative to the outer shell 81, thereby achieving the telescopic protection function.
[0056] Based on the above embodiments, referring to Figure 1 Furthermore, in order to slow down the lifting speed of the height-adjustable table and prevent the tabletop 1 from rising and falling suddenly, and to ensure operational safety and stability, a damping telescopic component 4 is provided between the two first connecting rods 21 and the two second connecting rods 31. Through the slow release effect of the damping telescopic component 4, the height-adjustable table is released slowly to improve safety.
[0057] Specifically, the damping telescopic component 4 is a damping gas spring 41 or a spring. Taking the damping gas spring 41 as an example, its two ends are rotatably connected between the two first connecting rods 21 and the two second connecting rods 31, so that it can rotate relative to each other during telescopic movement. Specifically, a connecting rod can be set between the two first connecting rods 21 and the two second connecting rods 31, and then a rotating seat 42 is set in the middle of the connecting rod. The two ends of the damping gas spring 41 are rotatably set in the rotating seat 42, thereby realizing the rotational connection between the damping gas spring 41 and the first connecting rods 21 and the second connecting rods 31.
[0058] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
