Description

A height-adjustable table with dual pneumatic rods

[0001] This utility model relates to the field of height-adjustable desks, and in particular to a height-adjustable desk with dual pneumatic rods. Background Technology

[0002] Currently, there are two types of height-adjustable desks: those placed on a table and those placed on the ground. Ground-based height-adjustable desks mainly fall into two categories: electrically driven desks and pneumatic desks using a pneumatic rod as the primary drive force. While electrically driven desks have many advantages, they require electricity and cannot be easily moved, making them inconvenient. Pneumatic desks, although easy to move, use a single pneumatic or hydraulic rod to adjust the desktop height. However, the travel of a single pneumatic rod is limited, often failing to meet the standing work height requirements of taller individuals. Therefore, a more structurally sound height-adjustable desk is urgently needed to solve these technical problems. Technical issues

[0003] In view of the shortcomings of the above-mentioned technology, which has limited lifting height of the tabletop due to a single gas spring, this utility model provides a lifting table with two gas springs. Technical solutions

[0004] To achieve the above objectives, this utility model provides a height-adjustable table with dual pneumatic rods, comprising a first base, a second base, a height-adjustable tabletop, a hollow telescopic support, and a first pneumatic rod and a second pneumatic rod fixedly disposed within the telescopic support.

[0019] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0020] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0021] In the existing technology, electric height-adjustable desks have the drawback of not being able to be moved at will, while pneumatic height-adjustable desks can be moved at will, but most pneumatic height-adjustable desks generally only use a single gas spring to achieve height adjustment, which limits the height of the desktop and cannot meet the needs of taller people. Therefore, there is an urgent need for a reasonable height-adjustable desk to solve the above-mentioned technical problems.

[0022] Please refer to Figure 1. This utility model discloses a height-adjustable table with dual pneumatic rods, comprising a first base 1, a second base 2, a height-adjustable tabletop 3, a hollow telescopic support 4, and a first pneumatic rod 5 and a second pneumatic rod 6 fixedly installed within the telescopic support 4. Both ends of the telescopic support 4 are fixedly connected to the first base 1 and the second base 2, respectively. The height-adjustable tabletop 3 is flip-connected to the second base 2. The first pneumatic rod 5 and the second pneumatic rod 6 also include a first adjusting member 7 for controlling the extension and retraction of the first pneumatic rod 5 and a second adjusting member 8 for controlling the extension and retraction of the second pneumatic rod 6. One end of the first adjusting member 7 abuts against the push rod of the first pneumatic rod 5. The second adjusting member 8 is fixedly installed on the height-adjustable tabletop 3. The second base 2 has a pressure contact head 9 hinged to the second base 2, and one end of the second adjusting member 8 is fixedly connected to the pressure contact head 9. This application adjusts the extension and retraction lengths of the first pneumatic rod 5 and the second pneumatic rod 6 using the first adjusting member 7 and the second adjusting member 8 to increase the upper limit of the tabletop height, allowing people of all heights to use the table in either a standing or sitting posture, thus improving the product's flexibility. Embodiments of the present invention

[0023] The working principle of this utility model is as follows:

[0024] In use, the desktop height can be adjusted via the first adjusting member 7 and the second adjusting member 8. The telescopic bracket 4 contains two independent sections: the first gas spring 5 and the second gas spring 6. By stepping on the pressure plate that presses the first adjusting member 7, the end of the first adjusting member 7 that abuts against the push rod of the first gas spring 5 tilts upward, pressing against the air pressure release button 15 on the push rod. This opens the air passage of the first gas spring 5, allowing adjustment of its push rod. The second gas spring 6, by pressing upward against the second adjusting member 8, causes the pressure contact head 9 to press downward against the air pressure release button 15, connecting the air pressure of the second gas spring 6 with the external pressure. Pushing the push rod outward causes the multi-stage telescopic rod of the telescopic bracket 4 to extend via two sections of pneumatic rods, raising the desktop to a position suitable for the user. Pressing the flip adjustment plate 100 on the first desktop 31 causes the pneumatic release button 15 of the flip connecting rod 101 to be pressed by the flip adjustment plate 100. After the air passage of the third pneumatic rod is opened, the first desktop 31 can also be flipped at a certain angle relative to the second base 2, adjusting to the optimal angle according to the user's standing or sitting posture. The stop block 11 on the first desktop 31 can prevent items from slipping when tilted, while the second desktop 32 is horizontal relative to the user, allowing items to be placed normally.

[0025] In this embodiment, the first pneumatic rod 5 and the second pneumatic rod 6 each include their own push rods and a pneumatic release button 15 on the end face of the push rod. The extension and retraction of the first pneumatic rod 5 and the second pneumatic rod 6 can be controlled by the first adjusting member 7 and the second adjusting member 8, respectively. One end of the first adjusting member 7 abuts against the pneumatic release button 15 of the first pneumatic rod 5. When the end of the first adjusting member 7 away from the first pneumatic rod 5 is pressed, the other end is forced to rise and press against the pneumatic release button 15, so that the internal air pressure of the first pneumatic rod 5 is connected to the external air pressure. At this time, the extension and retraction of the push rod can be adjusted. Applying an upward force to the lifting table can drive the push rod. One end of the push rod of the second pneumatic rod 6 is fixedly connected to the first table 31. Similarly, pressing the second adjusting member 8 causes the connecting rod connected to the second adjusting member 8 to drive the pressure contact head 9 to move downward, so that the pneumatic release button 15 of the push rod of the second pneumatic rod 6 is pressed by the pressure contact head 9. At this time, applying an upward force to the lifting table can drive the push rod. Moving the lever upwards raises the desktop position, and releasing the gas pressure release button 15 fixes the current height position of the adjustable desktop. The first gas lever 5 and the second gas lever 6 increase the upper limit of the desktop height, allowing people of different heights to use it in a standing or sitting position, improving the product's flexibility. Furthermore, a buffer spring 14 is included. One end of the buffer spring 14 abuts against the first gas lever 5, and the other end abuts against the first adjusting member 7. When the user adjusts the desktop height by pressing the first adjusting member 7 with their foot, it is difficult to control the amount of force applied by the foot, which may cause the first adjusting member 7 to be subjected to a large amount of gravity, resulting in damage or breakage. Therefore, by setting up the buffer spring 14, the damping is increased to offset the gravity on the first adjusting member 7, reducing the gravity on the first adjusting member 7. To a certain extent, it also allows the user to feel the buffer feedback provided by the buffer spring 14 when pressing to adjust, thereby improving the adjustment quality.

[0026] In this embodiment, the lifting tabletop 3 includes a first tabletop 31 and a second tabletop 32. The first tabletop 31 is provided with a flipping assembly 10, and the first tabletop 31 is flipped and connected to the first base 1 through the flipping assembly 10. The second tabletop 32 is fixedly disposed on one side of the first tabletop 31. The flipping assembly 10 includes a flipping adjustment plate 100, a flipping connecting rod 101, and a flipping hinge 102. The first tabletop 31 is flipped and connected to the second base 2 through the flipping hinge 102. The flipping adjustment plate 100 is connected to one end of the flipping connecting rod 101, and the other end of the flipping connecting rod 101 is hinged to the second base 2. By pressing the flipping adjustment plate 100, the first tabletop 31 can be rotated at a certain angle relative to the second base 2. The tilting adjustment allows users to freely adjust the angle of the first desktop 31, flexibly adapting to a comfortable usage angle and work environment based on the user's sitting or standing posture. In situations with limited space, raising and tilting the desktop can reduce the space occupied by the desktop to a certain extent. Furthermore, a stop 11 is provided on the edge of the first desktop 31, which is fixedly installed on the first desktop 31. When the first desktop 31 is tilted, the stop 11 can prevent items such as computers and books from slipping off. The second desktop 32 is an independent desktop separate from the first desktop 31, and it has both flip and horizontal desktop features. After the first desktop 31 is flipped, items can be placed on the horizontal second desktop 32.

[0027] In this embodiment, the telescopic bracket 4 includes a first telescopic rod 41, a second telescopic rod 42, and a third telescopic rod 43 that are sequentially connected. A first pneumatic rod 5 and a second pneumatic rod 6 are fixedly installed inside the second telescopic rod 42. When the push rods of the first pneumatic rod 5 and the second pneumatic rod 6 move, they drive the second telescopic rod 42 and the third telescopic rod 43 to extend and retract. Since the second telescopic rod 42 is fixedly engaged with the first pneumatic rod 5 and the second pneumatic rod 6, when the two pneumatic rods extend and retract, the second telescopic rod 42 and the third telescopic rod 43 are driven to extend and retract by the push rods of the first pneumatic rod 5 and the second pneumatic rod 6, thereby increasing the height of the desktop. Industrial applicability

[0028] The advantages of this utility model are:

[0029] 1) This utility model improves the height adjustment limit of the desktop by setting two gas springs, making it suitable for people of different heights and meeting the needs of sitting and standing postures, thus improving the product's flexibility.

[0030] 2) The first desktop can be adjusted relative to the second base at a certain angle via a flip adjustment lever. Users can adjust the angle of the first desktop according to their own sitting posture needs, which improves the comfort of using the product to a certain extent.

[0031] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
