Description

Technical Field

[0001] This utility model relates to the field of height-adjustable desks, and in particular to a multi-functional tabletop for height-adjustable desks. Background Technology

[0002] A height-adjustable desk is an innovative type of desk with adjustable height. Through electric or manual mechanisms, the desktop height can be easily changed, allowing users to freely switch between sitting and standing postures according to their needs. This effectively alleviates physical fatigue caused by maintaining the same posture for extended periods and has a positive effect on preventing cervical and lumbar spine diseases. The tabletop, as a crucial component of the desk, is made of various materials, such as solid wood and engineered wood. The surface is usually specially treated, making it wear-resistant, scratch-resistant, and easy to clean, providing users with a flat and comfortable working and studying surface to meet the needs of different scenarios.

[0003] Existing height-adjustable desks are mostly made of wood and lack magnetic attachment. Writing is not possible directly on wooden surfaces. In the process of working, studying, and creating, inspiration is fleeting. If the desktop cannot be used for direct writing, one must first find draft paper or a notebook to jot down ideas quickly, interrupting the flow of thought and affecting efficiency. Furthermore, because the desktop lacks magnetic attachment, metal pens, compasses, and other tools easily roll or slip off. Users cannot use magnetic clips to secure paper to the desktop. Moreover, most existing height-adjustable desks lack angle adjustment mechanisms, preventing the desktop from being adjusted to a suitable and comfortable angle for use. Prolonged use can easily lead to shoulder pain.

[0004] Therefore, there is an urgent need to provide a multi-functional tabletop for height-adjustable desks to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-functional tabletop for height-adjustable desks.

[0006] To solve the above-mentioned technical problems, the present invention provides a multi-functional tabletop for a height-adjustable desk, comprising a support mechanism and a connecting mechanism. The support mechanism is fixed with a lifting mechanism for adjusting the height of the tabletop, and the top of the lifting mechanism is fixed with a connecting mechanism for mounting the tabletop.

[0007] A desktop mechanism is rotatably connected to the connecting mechanism;

[0008] The desktop mechanism has two fixed limiting mechanisms.

[0009] The present invention is further configured such that: the support mechanism includes a square tube, both ends of which are welded and fixed with support feet, and the bottom end of the support feet is rotatably connected with a caster wheel.

[0010] Through the above technical solution, the support feet and the square tube are not perpendicular to each other. The square tube and the two support feet form a trapezoidal support structure, which effectively improves the anti-tilting ability of the device. In addition, the distance between the support feet facing the user is relatively wide, which can effectively prevent the support feet from colliding with the user's feet. The casters allow the user to move the device easily. The casters are lockable casters. When the user needs to position the device, he can step on the locking plate, at which time the casters cannot roll.

[0011] The present invention is further configured such that: the lifting mechanism includes a lifting air rod welded and fixed to one end of a square tube, an air valve is fixed to the top end of the lifting air rod, and an adjusting handle is movably disposed on the air valve.

[0012] Through the above technical solution, the adjustment handle can control the opening and closing of the air valve. When the user presses the adjustment handle with his / her finger, the air valve opens. At this time, the user can adjust the lifting air rod up and down. When the height is adjusted to the specified height, the user can release the adjustment handle. At this time, the air valve closes, and the height of the lifting air rod is fixed under the action of air pressure.

[0013] The present invention is further configured such that: the connecting mechanism includes a connector fixed to the top of the air valve, one end of the connector has a rotating connecting hole, and the connector also has a sliding groove.

[0014] With the above technical solution, the connector is welded from a metal square tube, and the rotating connection hole and the slide groove are at the same height.

[0015] The present invention is further configured such that: a push rod is slidably connected to the connector, one end of the push rod is fixed with a handle, the other end of the push rod is fixed with a limit rod, and two springs are fixed on the limit rod.

[0016] With the above technical solution, the limiting rod is slidably connected to the slide groove, and the bottom end of one side of the limiting rod is arc-shaped. When the user pushes the handle, the push rod will push the limiting rod to move to one end of the slide groove. When the user releases the handle, the two springs will pull the limiting rod to the other end of the slide groove.

[0017] The present invention is further configured such that: the desktop mechanism includes a rotating connecting part rotatably connected to the rotating connecting hole, a desktop plate is fixed to the top of the rotating connecting part, a magnetic layer is fixed to the inner side of the desktop plate, and a surface layer is fixed to the top of the magnetic layer.

[0018] Through the above technical solution, the desktop board is rotatably connected to the connecting mechanism via a rotating connecting part. The magnetic layer is magnetic, allowing users to directly attach metal items such as metal pens, metal compasses, magnetic buckles, and metal rulers to the desktop board, effectively preventing tools from rolling or falling. The surface is made of painted aluminum alloy, which is smooth and wear-resistant. Users can directly write on the desktop using whiteboard markers, and the writing can be easily erased with an eraser or a cloth, effectively improving the ease of use of the device.

[0019] The present invention is further configured such that: the limiting mechanism includes a connecting plate fixed to the bottom end of the desktop board, a limiting arc plate is welded and fixed to the bottom end of the connecting plate, and a plurality of limiting slots are provided on the limiting arc plate.

[0020] Through the above technical solution, the connecting plate can be fixed to the desktop panel with screws. The center of the limiting arc plate coincides with the circle of the rotating connecting hole. The bottom end of the limiting slot is arc-shaped and the top end is flat. When the user needs to adjust the angle of the desktop, he can directly rotate the desktop panel upward. At this time, since the bottom end of the side of the limiting rod that contacts the limiting slot is arc-shaped, the limiting rod will be squeezed out of the limiting slot under the mutual compression of the arc surfaces, so that the desktop panel can rotate upward normally. When the user releases the desktop panel when it is rotated to the specified height, the limiting rod will re-enter the limiting slot under the action of the spring, realizing the positioning of the desktop panel angle. Since the top end of the limiting slot is flat, when the desktop panel is subjected to downward pressure, the limiting rod will block the limiting slot, preventing the desktop panel from rotating downward. When the user needs to adjust the desktop panel downward, he can grasp and gently push the handle to push the limiting rod out of the limiting slot.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting up a support mechanism, lifting mechanism, connecting mechanism, desktop mechanism and limiting mechanism, this utility model effectively improves the stability of the device, and the user can also easily adjust the height and angle of the device, thus improving the applicability of the device;

[0023] 2. This utility model effectively improves the strength of the desktop by setting up a desktop mechanism, avoiding desktop wear. The desktop can be used for writing directly, and the desktop can adsorb various metal items and tools, effectively improving the convenience and practicality of the device.

[0033] Please see Figures 1-7 A multi-functional tabletop for a height-adjustable desk includes a support mechanism 1 and a connecting mechanism 3. The support mechanism 1 includes a square tube 101, with support legs 102 welded to both ends of the square tube 101. A caster wheel 103 is rotatably connected to the bottom of the support legs 102. The support legs 102 and the square tube 101 are not perpendicular to each other. The square tube 101 and the two support legs 102 form a trapezoidal support structure, which effectively improves the anti-tilting ability of the device. The support legs 102 have a wider spacing at the end facing the user, which can effectively prevent the support legs 102 from colliding with the user's feet. The caster wheel 103 allows the user to move the device easily. The caster wheel 103 is a locking caster wheel 103. When the user needs to position the device, he can step on the locking plate, at which time the caster wheel 103 cannot roll.

[0034] like Figure 1 and Figure 2As shown, a lifting mechanism 2 for adjusting the height of the desktop is fixed on the support mechanism 1. The lifting mechanism 2 includes a lifting air rod 201 welded and fixed to the top of the square tube 101. An air valve 202 is fixed to the top of the lifting air rod 201. An adjusting handle 203 is movably disposed on the air valve 202. The adjusting handle 203 can control the opening and closing of the air valve 202. When the user presses the adjusting handle 203 with his / her finger, the air valve 202 opens. At this time, the user can adjust the lifting air rod 201 up and down. When the height is adjusted to the specified height, the user can release the adjusting handle 203. At this time, the air valve 202 closes, and the height of the lifting air rod 201 is fixed under the action of air pressure.

[0035] like Figure 1 and Figure 4 As shown, the top of the lifting mechanism 2 is fixed with a connecting mechanism 3 for mounting the tabletop. The connecting mechanism 3 includes a connector 301 fixed to the top of the air valve 202. One end of the connector 301 has a rotating connecting hole 302, and the connector 301 also has a sliding groove 303. A push rod 304 is slidably connected to the connector 301. One end of the push rod 304 is fixed with a handle 305, and the other end of the push rod 304 is fixed with a limit rod 306. Two springs are fixed on the limit rod 306. Spring 307 and connector 301 are welded from metal square tubes. Rotary connecting hole 302 and slide groove 303 are at the same height. Limiting rod 306 is slidably connected to slide groove 303, and the bottom end of one side of limiting rod 306 is arc-shaped. When the user pushes handle 305, push rod 304 will push limiting rod 306 to move it to one end of slide groove 303. When the user releases handle 305, two springs 307 will pull limiting rod 306 to the other end of slide groove 303.

[0036] like Figure 1 ,and Figures 5-7As shown, a desktop mechanism 4 is rotatably connected to the connecting mechanism 3. The desktop mechanism 4 includes a rotating connecting part 401 that is rotatably connected to the rotating connecting hole 302. A desktop plate 402 is fixed to the top of the rotating connecting part 401. A magnetic layer 403 is fixed to the inner side of the desktop plate 402. A surface layer 404 is fixed to the top of the magnetic layer 403. The desktop plate 402 is rotatably connected to the connecting mechanism 3 through the rotating connecting part 401. The magnetic layer 403 is magnetic, allowing the user to attach metal items such as metal pens, metal compasses, magnetic snaps, and metal rulers when using the device. It is directly adsorbed onto the desktop 402, effectively preventing tools from rolling or falling. The surface layer 404 is made of painted aluminum alloy, which is smooth and wear-resistant. Users can write directly on the desktop with whiteboard markers, and the writing can be easily erased with an eraser or a cloth, effectively improving the ease of use of the device. Two limiting mechanisms 5 are fixed on the desktop mechanism 4. The limiting mechanism 5 includes a connecting plate 501 fixed to the bottom of the desktop 402. A limiting arc plate 502 is welded to the bottom of the connecting plate 501. The limiting arc plate 502 has an opening There are multiple limiting slots 503. The connecting plate 501 can be fixed to the desktop panel 402 with screws. The center of the limiting arc plate 502 coincides with the circle of the rotating connecting hole 302. The bottom end of the limiting slot 503 is arc-shaped and the top end is flat. When the user needs to adjust the angle of the desktop, he can directly rotate the desktop panel 402 upward. At this time, since the bottom end of the limiting rod 306 that contacts the limiting slot 503 is arc-shaped, the limiting rod 306 will be squeezed out of the limiting slot 503 under the mutual compression of the arc surfaces, so that the desktop panel 402 can rotate upward normally. When the desktop 402 is rotated to the specified height, the user releases the desktop 402. The limiting rod 306 will re-engage in the limiting slot 503 under the action of the spring 307, thereby positioning the angle of the desktop 402. Since the top of the limiting slot 503 is flat, when the desktop 402 is subjected to downward pressure, the limiting rod 306 will block the limiting slot 503, preventing the desktop 402 from rotating downward. When the user needs to adjust the desktop 402 downward, he / she can push the handle 305 to push the limiting rod 306 out of the limiting slot 503.

[0037] In use, the support mechanism 1 effectively improves the stability of the device. The user can adjust the desktop mechanism 4 to a suitable height through the lifting mechanism 2, and then adjust the desktop mechanism 4 to a suitable angle for use through the connecting mechanism 3 and the limiting mechanism 5.
