Description

Technical Field

[0001] This application relates to the field of desk technology, and in particular to an adjustable desk. Background Technology

[0002] Height-adjustable desks, as a type of office furniture, are widely used in homes, offices, and educational institutions. As people's demands for work environment comfort increase, height-adjustable desks are gradually becoming an important part of modern office equipment. They not only meet the needs of people of different heights but also effectively alleviate physical fatigue caused by maintaining the same posture for extended periods, thereby improving work efficiency and quality of life.

[0003] Modern height-adjustable desks typically consist of upper and lower legs and a tabletop. The upper and lower legs are secured together via through holes and bolts. Users loosen the bolts, raise the upper leg to a preset position, and then secure it with bolts through the upper and lower legs, thus adjusting the desk's height. However, this method requires careful observation of the alignment of the through holes between the upper and lower legs during raising and lowering before securing with bolts. Otherwise, errors can easily occur, which is not only time-consuming but also prone to inaccurate positioning due to improper operation, affecting user comfort. Utility Model Content

[0004] This application provides a height-adjustable table to solve the problems of time-consuming and inconvenient operation caused by the need to check whether the table legs are aligned when adjusting them.

[0005] A height-adjustable desk, comprising:

[0006] The lower table legs are provided in two opposite directions. The lower table legs are hollow inside and have a fixing plate. The fixing plate extends along the height direction and has multiple fixing holes spaced apart along the height direction.

[0007] The upper table leg has two corresponding lower table legs;

[0008] The adjustable component has two parts and is fixed to the upper table leg respectively. The upper table leg and the adjustable component can move up and down relative to the lower table leg. The adjustable component includes a pin. The pin passes through the upper table leg and extends into the lower table leg. When the pin moves upward, it can sequentially extend into each of the fixing holes to adjust the height.

[0009] The tabletop is located at the upper end of the upper table leg and its two ends are respectively fixed to the two upper table legs.

[0010] By adopting the above technical solution, the pin can sequentially insert into each fixing hole as it moves upward, making height adjustment extremely convenient. Users do not need to carefully observe whether the pin is aligned with the fixing hole; they can quickly adjust the height simply by moving the pin upward, saving adjustment time and effort.

[0011] In one embodiment, the fixing plate is further provided with a plurality of inclined grooves, each of which corresponds to a fixing hole. The fixing hole is located at the lower end of the inclined groove, and the pin can abut against the bottom of the inclined groove, retract, and then extend to be located in the fixing hole.

[0012] By adopting the above technical solution, the inclined grooves on the fixing plate correspond one-to-one with the fixing holes. The pin retracts when it abuts against the bottom of the inclined groove, and then extends and inserts into the fixing hole when aligned with it. At each fixing hole, the pin produces a "click" sensation, allowing the user to easily select the appropriate height without visual inspection, thus improving the accuracy of height adjustment. The user simply needs to slightly loosen the pin and move the upper table leg upwards; the pin will automatically engage with the inclined groove and the surface of the fixing plate, completing the retraction and extension action, and finally accurately falling into the fixing hole. This operation method is simple and easy to understand, lowering the user's barrier to entry.

[0013] In one embodiment, the lower table leg is provided with a movable hole, which is located on the surface of the lower table leg and extends vertically. The fixed plate corresponds to the movable hole. The adjusting member also includes a slider, which is fixed to the lower end of the upper table leg and passes through the movable hole into the lower table leg. The pin passes through the upper table leg, the slider, and the movable hole.

[0014] By adopting the above technical solution, the movable hole on the lower table leg provides a channel for the slider to move. The slider is fixed to the lower end of the upper table leg and extends into the lower table leg through the movable hole. The upper table leg is adjusted in height by moving the slider up and down. This design ensures the stability of the upper table leg during movement, avoids wobbling or deviation, and makes height adjustment smoother.

[0015] In one embodiment, the adjusting member includes a bolt that passes through the upper table leg and the slider and extends into the lower table leg to be fixed in the fixing hole, the length of the bolt being less than the length of the pin.

[0016] By adopting the above technical solution, the bolts in the adjusting component can fix the upper and lower table legs, forming a double fixation with the latch. When adjusting the height, first loosen the bolts. At this time, the latch can still fix the upper table leg to prevent it from falling. Then loosen the latch to move it up and down. After the latch is adjusted to the preset fixing hole, tighten the latch and bolt in sequence. This greatly enhances the firmness of the table leg connection and improves the safety and stability of the height-adjustable table.

[0017] In one embodiment, the lower table leg is further provided with an elastic element, the upper end of which is fixed to the slider. The adjusting element also includes a pulley, which is fixed to the slider and located on both sides of the fixed plate.

[0018] By adopting the above technical solution, the elastic component inside the lower table leg provides auxiliary force when the slider lifts the upper table leg, allowing the user to complete the lifting operation with only a small amount of force, which can be easily accomplished by one person. This is very practical for users with less strength or in scenarios where frequent height adjustments are needed. The elastic component also slows down the descent speed of the slider, making the tabletop descend more smoothly. This avoids items shaking or falling due to rapid descent of the tabletop, improving the user experience. At the same time, the rollers reduce friction when the slider moves, further making it easier to move the slider.

[0019] In one embodiment, the upper table leg is further provided with a through hole, and the pin and the bolt both pass through the through hole and the slider extends into the lower table leg, with the end of the pin able to protrude from the through hole.

[0020] By adopting the above technical solution, the through holes on the upper table legs facilitate the insertion of pins and bolts into the lower table legs, and the end of the pin protrudes from the through hole, allowing users to directly contact the pin with their hands or tools to easily control its loosening or tightening. This design optimizes the user experience and improves adjustment efficiency.

[0021] In one embodiment, the height-adjustable table further includes a U-shaped shelf located below the tabletop, with both ends of the shelf fixed to the two upper table legs respectively.

[0022] By adopting the above technical solution, the shelf is fixed to the two upper table legs, providing users with additional storage space. It can be used to hang chairs and other items, making it convenient for users to store and organize items, and improving the practicality and space utilization of the height-adjustable table.

[0023] In one embodiment, the outer surface of the movable rod is provided with a scale.

[0024] By adopting the above technical solution, users are provided with an intuitive height reference. Users can accurately adjust the height of the desktop according to the scale to ensure that it is adjusted to a suitable height position, thus improving the accuracy and convenience of height adjustment.

[0025] In one embodiment, the upper end of the movable rod is provided with a hidden hook, which is located inside the upper table leg and can extend out of the upper table leg.

[0026] By adopting the above technical solution, the hook can extend out of the upper table leg, making it convenient for users to hang items such as backpacks, avoiding the backpacks taking up space on the ground or tabletop and keeping the tabletop tidy; at the same time, when not in use, it can be stored inside the upper table leg without affecting the overall aesthetics and usable space of the tabletop, and has a high degree of flexibility.

[0027] In one embodiment, the desktop panel is provided with a baffle.

[0028] By adopting the above technical solution, items on the desktop can be effectively prevented from slipping, protecting their safety and avoiding damage or loss caused by slipping. Especially when a user accidentally bumps into the desktop or the desktop tilts, the barrier strip provides excellent protection, improving safety during use.

[0029] In summary, this application includes at least one beneficial effect:

[0030] 1. The slots on the mounting plate correspond one-to-one with the mounting holes. The pin retracts when it abuts against the bottom of the slot, and then extends and inserts into the mounting hole when aligned. Each time the pin reaches a mounting hole, it provides a "click" sensation, allowing users to easily select the appropriate height without visual inspection, thus improving the accuracy of height adjustment. Users simply need to slightly loosen the pin and move the upper table leg upwards; the pin will automatically engage with the slot and the surface of the mounting plate, completing the retraction and extension motion before accurately entering the mounting hole. This simple and intuitive operation lowers the barrier to entry for users.

[0031] 2. The bolts in the adjusting mechanism can fix the upper and lower table legs, forming a double fixation with the latch. When adjusting the height, first loosen the bolts. At this time, the latch can still fix the upper table leg to prevent it from falling. Then loosen the latch to move it up and down. After the latch is adjusted to the preset fixing hole, tighten the latch and bolt in sequence. This greatly enhances the firmness of the table leg connection and improves the safety and stability of the height-adjustable table.

[0032] 3. The elastic element inside the lower table leg provides assistance when the slider raises the upper table leg, allowing users to complete the raising operation with minimal effort, easily accomplished by one person. This is particularly useful for users with less strength or in scenarios requiring frequent height adjustments. The elastic element also slows down the slider's descent, making the tabletop's descent smoother. This prevents items from wobbling or falling due to rapid descent, improving the user experience. Simultaneously, the casters reduce friction during slider movement, further enhancing ease of movement. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-6 The adjustable desk provided in this application will be described in further detail.

[0041] Example 1

[0042] Please see Figure 1-6 The present application provides a height-adjustable table 1, which includes a lower table leg 11, an upper table leg 12, an adjusting member 13, and a tabletop 14.

[0043] like Figures 1 to 4 As shown, there are two lower table legs 11 arranged opposite each other. Each lower leg is hollow and has a fixing plate 111. The fixing plate 111 extends along the height direction and has multiple fixing holes 1111 spaced apart along the height direction. There are two upper table legs 12, located opposite the lower table legs 11. Specifically, the lower table legs 11 can be metal tubes, hollow inside, and made of stainless steel or aluminum alloy to ensure strength and durability. The fixing plates 111 can be stainless steel or aluminum alloy plates, with a thickness generally between 2mm and 5mm to ensure sufficient strength. The fixing holes 1111 can be circular or elliptical, with the same distance between every two fixing holes 1111. The upper table legs 12 are also made of rectangular metal tubes and can use the same material as the lower table legs 11.

[0044] Two adjusting members 13 are provided, each fixed to its corresponding upper table leg 12. The upper table leg 12 and the adjusting member 13 can move up and down relative to the lower table leg 11. The adjusting member 13 includes a pin 131, which passes through the upper table leg 12 and extends into the lower table leg 11. When the pin 131 moves upward, it can sequentially extend into each fixing hole 1111 to adjust the overall height. Specifically, the pin 131 can be a cylindrical steel column or a threaded rod. The surface of the pin 131 can be provided with anti-slip texture to increase friction and prevent slippage. The length of the pin 131 should be slightly longer than the wall thickness of the lower table leg 11 to ensure that the pin 131 can be firmly inserted into the fixing hole 1111. The pin 131 is fixed to the upper table leg 12 by a nut, which can be a self-locking nut to prevent loosening.

[0045] The fixing plate 111 is also provided with multiple inclined grooves 1112, each corresponding to a fixing hole 1111. The fixing hole 1111 is located at the lower end of the inclined groove 1112. The pin 131 can abut against the bottom of the inclined groove 1112, retract, and then extend to be positioned in the fixing hole 1111. Specifically, the inclined groove 1112 can be designed as a straight line or an arc, and its width should be slightly larger than the diameter of the pin 131 to ensure that the pin 131 can slide smoothly into the fixing hole 1111. The lower end of the pin 131 may be equipped with a spring. Under normal circumstances, the pin 131 is fixed in the fixing hole 1111. After slightly loosening the pin 131, the slider 132 is moved vertically upwards. The pin 131 can abut against the bottom surface of the inclined groove 1112 and then against the surface of the fixing plate 111. During this process, the spring is continuously compressed until it corresponds to the next fixing hole 1111. The spring extends and pushes the pin 131 into the fixing hole 1111, which makes it easy to position each gear through the pin 131 without the need for personnel confirmation.

[0046] The lower table leg 11 is provided with a movable hole 112, which is located on the surface of the lower table leg 11 and extends vertically. The fixed plate 111 corresponds to the movable hole 112. The adjusting component 13 also includes a slider 132, which is fixed to the lower end of the upper table leg 12 and extends into the lower table leg 11 through the movable hole 112. The pin 131 passes through the upper table leg 12, the slider 132, and the movable hole 112. Specifically, the slider 132 can be a metal block or a plastic block, and its shape can be rectangular or circular.

[0047] The lower table leg 11 may also be equipped with an elastic element 113. The upper end of the elastic element 113 is fixed to the slider 132. The adjusting element 13 also includes a pulley 134, which is located inside the lower table leg 11, fixed to the slider 132, and positioned on both sides of the fixed plate 111. Specifically, the elastic element 113 can be a gas spring or an air pump, etc., and its function is to assist the upward movement of the slider 132 while slowing down the downward speed of the slider 132. The pulley 134 can be a metal wheel or a plastic wheel to ensure that the pulley 134 can rotate freely and reduce friction.

[0048] The adjusting component 13 may also include a bolt 133, which passes through the upper table leg 12 and the slider 132 and extends into the lower table leg 11 to be fixed in the fixing hole 1111. The length of the bolt 133 is less than the length of the pin 131. Specifically, the bolt 133 can be a hex bolt 133 or an internal hex bolt 133 for easy tightening and loosening. In this embodiment, there are two bolts 133 located at both ends of the pin 131 in the vertical direction. The bolt 133 is also provided with a spring, which can be compressed when the bolt 133 is fixed in the fixing hole 1111 to prevent it from being fixed too quickly; it can also speed up the separation process when the bolt 133 is loosened. The through hole between two adjacent fixing holes 1111 is used to fix the fixing plate 111 in the lower table leg 11, and the pin 131 cannot extend into the through hole. The upper table leg 12 is also provided with a through hole 121. The pin 131 and the bolt 133 both pass through the through hole 121 and extend into the lower table leg 11 via the slider 132. The end of the pin 131 can protrude from the through hole 121. Therefore, the length of the bolt 133 is slightly shorter than that of the pin 131. The through hole 121 can be designed to be circular or elliptical, and its position should match the installation position of the pin 131 and the bolt 133.

[0049] The outer surface of the upper table leg 12 is equipped with a scale, which can intuitively display the current height setting.

[0050] like Figures 5 to 6 As shown, a hidden hook 16 is provided at the upper end of the upper table leg 12. The hook 16 is located inside the upper table leg 12 and can extend outward for hanging items such as school bags. In this embodiment, the hook 16 includes a limiting block 161 and a baffle 162. The limiting block 161 is located inside the upper table leg 12 and is connected to the inner wall of the upper table leg 12 by a spring. The baffle 162 is connected to the limiting block 161 and can abut against the upper table leg 12. The baffle 162 can be flush with the outer surface of the upper table leg 12 and its lower end is exposed for easy pulling out. By pulling the baffle 162 outward, the limiting block 161 moves inside the upper table leg 12 and stretches the spring until the limiting block 161 abuts against the inner wall of the upper table leg 12. Then, the school bag is hung on the limiting block 161 and blocked by the baffle 162, making it difficult for the school bag to come off. Subsequently, when released, the limiting block 161 retracts under the action of the spring.

[0051] The tabletop 14 is located at the upper end of the upper table legs 12 and is fixed to the two upper table legs 12 at both ends. Specifically, the tabletop 14 may be equipped with a baffle 141, which can be made of plastic or metal. The baffle 141 is fixed to the tabletop 14 at its bottom by screws or clips to prevent items from slipping off the table. The tabletop 14 can be made of wood or composite material, with a thickness generally between 10mm and 30mm to ensure sufficient strength and stability. The edges of the tabletop 14 can be chamfered to prevent scratches to the user. A wear-resistant layer can be applied to the upper surface of the tabletop 14 to increase its service life.

[0052] The height-adjustable table 1 also includes a U-shaped shelf 15, with both ends of the shelf 15 fixed to the upper ends of the two upper table legs 12. In this embodiment, the shelf 15 is tilted and has multiple storage holes at the higher end, making it easy to place chairs and preventing them from falling off.

[0053] The implementation principle of this embodiment is as follows: Under normal circumstances, both bolt 133 and pin 131 are fixed to the fixing holes 1111 on the fixing plate 111. When bolt 133 is loosened, slider 132 can still be fixed by pin 131. When it is necessary to rise, first loosen bolt 133, then slightly loosen pin 131 to control slider 132 to move upward. Pin 131 can retract and abut against inclined groove 1112 until it abuts against the surface of fixing plate 111. When pin 131 is aligned with the next fixing hole 1111, it extends to facilitate the selection of a suitable gear. When it is necessary to descend, fully loosen pin 131 to control slider 132 to move down to the bottom. After the height is adjusted, first tighten pin 131, then tighten bolt 133 to achieve fixation.

[0054] The fixing holes 1111 and pins 131 on the fixing plate 111 ensure that the slider 132 can be locked in each position without the user needing to check for alignment, saving time. The design of the pulley 134 and elastic element 113 effectively reduces the force required for the slider 132 to rise, while improving the smoothness of its movement, making it easy for one person to operate. The addition of auxiliary components such as the shelf 15, ruler, and hooks 16 further enhances the practicality and convenience of the height-adjustable desk 1. This design not only simplifies the height adjustment process but also improves safety, meeting students' dual needs for convenience and safety.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
