Abstract
Description
Technical Field
[0001] This invention relates to the field of office furniture technology, and more particularly to a height-adjustable desk. Background Technology
[0002] An office desk is a table provided for convenience in daily life, work, and social activities. In modern urban work, office workers spend most of their day at their desks, and prolonged sitting is very detrimental to health. When a person is sitting in a chair, the intervertebral discs of the lumbar spine bear more pressure than when standing, which can easily cause lower back pain. Maintaining the same posture for a long time can also cause pain and discomfort in the shoulders, arms, and neck.
[0003] However, the harm of prolonged sitting can be mitigated by simply alternating between sitting and standing. People can reduce the harm of prolonged sitting by switching between these two work modes. Currently, because traditional desks are not height-adjustable, they do not easily meet the needs of people who want to work standing up. Therefore, there is still room for improvement. Summary of the Invention
[0004] In response to the problem that traditional office desks cannot be adjusted in height, making them unsuitable for office workers who need to stand while working, this invention provides a height-adjustable office desk. This solves the problem of traditional office desks not being able to be adjusted in height, thus allowing office workers to work more comfortably while standing.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A height-adjustable desk includes a desktop and legs located at the bottom of the desktop. The side wall of the desktop has a notch, and a lifting plate for placing a computer screen is movably connected to the notch. One side of the lifting plate is provided with a drive component for moving the lifting plate away from or towards the legs. A baffle for protecting the computer screen is movably connected to the desktop. The desktop has a sliding hole for the baffle to be movably connected to the notch. The baffle is provided with a stabilizing component for stabilizing the position of the baffle.
[0006] By employing the above technical solution, the baffle is pulled so that it protrudes from the top of the desktop. Then, a driving stabilizer stabilizes the baffle at the protruding position. The driving mechanism then moves the lifting plate away from the table legs, causing the computer screen to move away from the table legs as well. This height adjustment of the lifting plate allows the desk to be raised and lowered, better meeting the needs of people working while standing. It also allows people to switch between sitting and standing work modes, reducing the harm caused by prolonged sitting. Furthermore, the baffle reduces the risk of the computer screen falling off the lifting plate due to wobbling during its movement, thus protecting the screen.
[0007] The present invention is further configured such that: the stabilizing component includes a rubber ring disposed on the side wall of the baffle, and a plurality of the rubber rings are provided, which are evenly distributed on the side wall of the baffle near the two ends of the baffle along the height direction, and the side wall of the sliding hole is provided with a locking groove for the rubber rings to be engaged.
[0008] By adopting the above technical solution, the rubber ring engages with the locking groove by pulling the baffle away from the table leg or pushing the baffle closer to the table leg, so that the baffle can be stabilized in one place. This makes it simple and convenient to drive the stabilizing component to stabilize the position of the baffle by simply pulling the baffle away from the table leg or pushing the baffle closer to the table leg, which helps to simplify the operation steps of the stabilizing component.
[0009] The present invention is further configured such that: the baffle includes a short plate and a long plate rotatably connected to the side wall of one end of the short plate along the height direction; a plurality of rubber rings are respectively located at positions away from each other on the side walls of the short plate and the long plate; the baffle is provided with a limiting member for restricting the long plate or the short plate from rotating to the side of the baffle close to the lifting plate; when the baffle protrudes from the top of the tabletop, the short plate moves away from the tabletop.
[0010] By adopting the above technical solution, the design of the short and long boards helps to reduce the situation where, when the baffle is placed at the bottom of the desktop and a person is using the desk of this invention, the baffle is close to the lifting platform, which obstructs the movement of people's feet and makes it inconvenient for people to use the height-adjustable desk. Instead, when a person is using the height-adjustable desk, they can push the long board to rotate it away from the lifting platform, making the space below the bottom of the desktop larger. This allows people to use the height-adjustable desk more comfortably, so that the baffle can protect the computer screen without hindering people from using the height-adjustable desk for work.
[0011] The invention is further configured such that: the limiting member is a hinge provided on the side wall of the baffle away from the tabletop, one side of the hinge is connected to the side wall of the short board and the long board respectively, and when one side of the short board abuts against one side of the long board, the short board and the long board are located on the same plane.
[0012] By adopting the above technical solution, and by setting the limiting component as a hinge and its position, when the long or short board rotates, it can only rotate to the side of the baffle away from the lifting plate. This helps to reduce the situation where the rubber ring on the short board gets stuck in the locking groove, and the long board rotates to the side of the baffle close to the lifting plate, causing the long board to occupy the space below the bottom of the lifting plate, making it difficult for people's feet to move in the space below the bottom of the lifting plate. This makes it easier for people to use the height-adjustable desk. At the same time, it helps to reduce the number of parts required to set the limiting component, making the setting of the limiting component simpler and more convenient.
[0013] The invention is further configured such that: the baffle is provided with an elastic element for always driving the short plate or the long plate to rotate in the direction of the lifting plate.
[0014] By adopting the above technical solution, when a person needs to stand up to work after sitting for a long time, the elastic element drives the long board to move towards the lifting platform, allowing the long board to automatically return to a position on the same plane as the short board. This makes it easier to lift the baffle away from the table legs. Simultaneously, when the baffle protrudes from the top of the desktop, the elastic element drives the short board to move towards the lifting platform, ensuring the short board remains on the same plane as the long board. This prevents the short board from rotating and continuously protects the computer screen. This reduces the risk of damage to the computer screen caused by shaking during the lifting process or by the user standing while working, which could result in the screen falling outside the baffle. The above design also makes it easier for users to pull the baffle away from the table corners and prevents the short board from rotating, thus protecting the computer screen.
[0015] The invention is further configured such that: the baffle is provided with a fixing member for restricting the rotation of the short plate.
[0016] By adopting the above technical solution, when the baffle is stably positioned protruding from the top of the desktop, the fixing component stabilizes the short board and restricts its rotation, making it less prone to rotation. This helps reduce the likelihood of the lifting table shaking when the lifting platform is raised to a higher position, which could cause the computer screen to fall outside the baffle and be damaged due to the short board easily rotating. The baffle is thus better able to protect the computer screen.
[0017] The invention is further configured such that: the fixing member includes a rotating rod rotatably connected within the short plate; one end of the rotating rod protrudes a pulling rod, which protrudes from the side of the short plate away from the long plate; the end of the rotating rod away from the pulling rod protrudes a locking rod, which faces the long plate; the side of the short plate away from the long plate has a recessed movable groove for the pulling rod to move; the side wall of the movable groove has a recessed rotating groove for the rotating rod to rotate; the side wall of the rotating groove has a movable hole for the locking rod to move; and the side wall of the short plate has a fixing groove for the locking rod to engage.
[0018] Using the above technical solution, when the baffle is stable in the position protruding from the top of the desktop, the pull rod is driven to move away from the long plate, causing the pull rod to pull the rotating rod to rotate. This causes the rotating rod to push the locking rod towards the long plate, so that the locking rod engages with the fixing groove, thereby fixing the short plate and the long plate. By driving the pull rod to move away from the long plate, the short plate and the long plate can be fixed, making it simple and convenient for the drive fixing component to fix the short plate and the long plate. This also makes the short plate less likely to rotate, which helps the baffle to better protect the computer screen.
[0019] The present invention is further configured such that: the driving component includes a support rod connected to the bottom of the lifting plate, and a cylinder is connected to the end of the support rod away from the lifting plate.
[0020] By adopting the above technical solution and setting the cylinder, when it is necessary to raise or lower the lifting platform of the desk, the support rod can be moved closer to or further away from the lifting platform simply by driving the cylinder. This allows the support rod to push the lifting platform to move closer to or further away from the desk legs, making it simple and convenient to drive the lifting platform to raise or lower, and simplifying the steps of operating the drive components.
[0021] In summary, the present invention has the following beneficial effects: 1. The design of the lifting platform, baffle, stabilizer, and drive mechanism helps to solve the problem of traditional desks not being able to be raised or lowered. This allows people to work standing up better when using height-adjustable desks, and also helps to protect computer screens.
[0022] 2. The design of the limiting and fixing components not only helps the baffle better protect the computer screen, but also allows people to use the desk more comfortably. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] A height-adjustable desk, see [link / reference] Figure 1 as well as Figure 2 The table includes a desktop panel 1 and table legs 11 located at the bottom of the desktop panel 1. The desktop panel 1 is rectangular in shape. A storage cabinet 12 is provided at the bottom of the desktop panel 1. A document rack 13 for placing documents is fixedly connected to the top wall of the desktop panel 1. The document rack 13 is located at one end of the top wall of the desktop panel 1 along the width direction. A notch 14 is cut off on the side of the desktop panel 1 away from the document rack 13 along the width direction. A lifting plate 15 for placing a computer screen is movably connected to the notch 14. A driving component 2 is provided on the side of the lifting plate 15 near the table legs 11 for driving the lifting plate 15 to move away from or towards the table legs 11. A baffle 3 for protecting the computer screen is movably connected to the desktop panel 1. A sliding hole for the baffle 3 to be movably connected is opened on the desktop panel 1. The sliding hole is near the notch 14. A stabilizing component is provided on the baffle 3 for stabilizing the position of the baffle 3.
[0030] See Figure 1 as well as Figure 2The table has two legs 11, located at one end of the tabletop 1 along its length and at both ends of the tabletop 1 along its width. The sidewalls of the legs 11 are fixedly connected to the bottom wall of the tabletop 1. A storage cabinet 12 is located at the end of the tabletop 1 away from the legs 11 along its length, and its top wall is fixedly connected to the bottom wall of the tabletop 1. A notch 14 is located at the end of the tabletop 1 away from the document holder 13 along its width. The notch 14 is rectangular, with a length three-sevenths the length of the tabletop 1, a width half the width of the tabletop 1, a distance one-seventh the length of the tabletop 1 from the notch 14 to the end of the tabletop 1 closest to the legs 11 along its length, and a distance one-seventh the length of the tabletop 1 from the notch 14 to the end of the tabletop 1 closest to the storage cabinet 12 along its length.
[0031] See Figure 1 as well as Figure 2 The height of the baffle 3 is half the height of the table leg 11. The baffle 3 includes a short plate 31 and a long plate 32 rotatably connected to the side wall of one end of the short plate 31 along the height direction. The height of the short plate 31 is one-third of the height of the baffle 3. The stabilizing component includes two rubber rings 33 disposed on the side wall of the baffle 3 along the height direction. The two rubber rings 33 are respectively located on the side wall of the short plate 31 and the long plate 32 along the height direction, and the two rubber rings 33 are far apart from each other. The stabilizing component also includes a locking groove on the side wall of the sliding hole for the rubber rings 33 to engage. In this embodiment, there are three baffles 3 and three sliding holes. The sliding holes surround the notch 14. When the baffle 3 protrudes from the top of the tabletop 1, the short plate 31 moves away from the tabletop 1.
[0032] See Figure 1 as well as Figure 2 The baffle 3 is provided with a limiting member 5 for restricting the rotation of the long plate 32 and the short plate 31 to the side of the baffle 3 close to the lifting plate 15. The limiting member 5 is a hinge provided on the side wall of the baffle 3 away from the tabletop 1. One side of the hinge is connected to the side wall of the short plate 31 and the long plate 32 away from the lifting plate 15, respectively. In this embodiment, there are six hinges, and two hinges are distributed on each baffle 3. When one side of the short plate 31 abuts against one side of the long plate 32, the short plate 31 and the long plate 32 are located on the same plane.
[0033] See Figure 1 as well as Figure 2 The baffle 3 is also provided with an elastic element 4 for continuously driving the short plate 31 or the long plate 32 to rotate toward the lifting plate 15. The elastic element 4 is a spring, one end of which is fixedly connected to the side wall of the short plate 31 away from the lifting plate 15, and the other end of which is fixedly connected to the side wall of the long plate 32 away from the lifting plate 15. In this embodiment, there are six elastic elements 4, and two elastic elements 4 are distributed on each baffle 3.
[0034] See Figure 3 as well as Figure 4 The baffle 3 also includes a fixing member 6 for restricting the rotation of the short plate 31. The fixing member 6 includes a rotating rod 62 rotatably connected to the short plate 31. One end of the rotating rod 62 protrudes with a pulling rod 61, which protrudes from the side of the short plate 31 away from the long plate 32. The other end of the rotating rod 62 away from the pulling rod 61 protrudes with a locking rod 63, which faces the long plate 32. The side of the short plate 31 away from the long plate 32 has a recessed movable groove 64 for the pulling rod 61 to move. The side wall of the movable groove 64 has a recessed rotating groove 65 for the rotating rod 62 to rotate. The side wall of the rotating groove 65 has a moving hole 66 for the locking rod 63 to move. A fixing groove 67 is provided on the side wall of the short plate 31 near the long plate 32 for the locking rod 63 to engage. A fixing rod 621 is rotatably connected to the side wall of the rotating groove 65. The fixing rod 621 passes through the side wall of the rotating rod 62. A through hole is provided on the side wall of the rotating rod 62 for the fixing rod 621 to pass through. The side wall of the fixing rod 621 is fixedly connected to the side wall of the through hole. By driving the pulling rod 61 to move away from the long plate 32, the pulling rod 61 drives the rotating rod 62 to rotate, thereby causing the rotating rod 62 to drive the locking rod 63 to move towards the long plate 32, so that the locking rod 63 engages with the fixing groove 67, thereby fixing the short plate 31 and the long plate 32.
[0035] See Figure 1 as well as Figure 2 The driving component 2 includes a support rod 21 fixedly connected to the bottom wall of the lifting plate 15 and a cylinder 22 connected to the side wall of the end of the support rod 21 away from the lifting plate 15. The telescopic rod of the cylinder 22 is fixedly connected to the side wall of the end of the support rod 21 away from the lifting plate 15. The lifting plate 15 is rectangular. There are two driving components 2. The two driving components 2 are located at both ends of the lifting plate 15 along the length direction and at the middle position of the lifting plate 15 along the width direction.
[0036] The implementation principle of this embodiment is as follows: When people use the height-adjustable desk to work while standing, they pull the three baffles 3 respectively, causing the baffles 3 to move away from the desk legs 11. This causes the rubber rings 33 on the long plate 32 to engage with the locking slots, thus stabilizing the baffles 3 on the side protruding from the desktop 1 away from the desk legs 11. The baffles 3 then surround the height-adjustable desk. Then, the pulling rod 61 is driven to move away from the long plate 32, causing the pulling rod 61 to rotate the rotating rod 62. The rotating rod 62 then causes the locking rod 63 to move towards the long plate 32, thus engaging the locking rod 63 with the fixing slot 67. This fixes the short plate 31 and the long plate 32. Then, the cylinder 22 is driven to move its extension rod towards the lifting plate 15, causing the extension rod of the cylinder 22 to move the lifting plate 15 away from the desk legs 11. This causes the lifting plate 15 to move the computer away from the desk legs 11, allowing people to work while standing using the height-adjustable desk.
[0037] When people need to sit down after standing for a period of time, pushing the pull rod 61 towards the long plate 32 causes the pull rod 61 to rotate the rotating rod 62, which in turn moves the locking rod 63 away from the long plate 32, separating the locking rod 63 from the fixing groove 67. Then, pushing the three baffles 3 towards the table leg 11 causes the rubber ring 33 on the short plate 31 to engage with the locking groove, placing the baffles 3 at the bottom of the desktop 1. Then, driving the cylinder 22 causes the extension rod of the cylinder 22 to move away from the lifting plate 15, which in turn moves the lifting plate 15 towards the table leg 11. The lifting plate 15 then moves the computer towards the table leg 11, allowing people to sit down to work. The lifting plate 15, cylinder 22, and support rod 21 enable the desk to meet the needs of standing work, and the baffles 3 help protect the computer screen.
[0038] By setting up the baffle 3, the stabilizer, and the limiting member 5, the baffle 3 can be pulled away from the table leg 11 to protect the computer screen. This helps reduce the shaking of the lifting plate 15 during the lifting process, which could cause the computer screen to shake and fall off the lifting plate 15. At the same time, when the baffle 3 is placed below the bottom of the desktop 1, people can push the long plate 32 with their feet to rotate it, which helps to increase the space under the desktop and makes it more comfortable for people to work with the height-adjustable desk of this invention. Even though the baffle 3 can protect the screen, it does not prevent people from working while seated.
[0039] By setting the fastener 6, when the baffle 3 is placed above the top of the desktop board 1, the short board 31 and the long board 32 are fixed by the fastener 6, making it less likely for the short board 31 to rotate, so that the baffle 3 can better protect the computer screen.
[0040] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
