Description

Technical Field

[0001] This utility model relates to the field of table technology, and in particular to a foldable desktop reading and writing terminal. Background Technology

[0002] Desktop reading and writing terminals are integrated data acquisition and processing devices designed specifically for desktop environments. They typically combine multiple input and output functions to meet the needs of efficient operation in office, commercial, or industrial scenarios.

[0003] Desktop reading and writing terminals are typically mounted on a desktop using a fixed stand to provide a stable position, but this mounting method has certain limitations. Due to the relatively simple design of the stand, it often uses rigid connections or fixed clips to fix the reading and writing device in a specific position, resulting in a lack of flexibility in adjusting its height and angle.

[0004] In actual use, different users have different heights, postures, and operating habits. A fixed installation height may force some users to maintain unnatural postures for extended periods, such as bending over or raising their arms, which can easily lead to fatigue or even muscle strain over time. Furthermore, because the angle is not adjustable, screen glare or the visibility of displayed content may be affected by changes in lighting or different viewing angles, impacting operating efficiency and user experience.

[0005] Furthermore, the fixed installation method cannot adapt to the personalized needs of different users, further reducing the versatility and comfort of the equipment. Although this rigid installation structure can ensure the stability of the equipment, it has obvious shortcomings in terms of ergonomics, making the use process inflexible and potentially affecting the comfort and operational accuracy during long-term work.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0047] Example

[0048] Please see Figures 1-7 As shown, this embodiment is a foldable desktop reading and writing terminal, including:

[0049] The support assembly 100 includes a folding tabletop 130 and a support frame 120 fixed to both ends of the lower surface of the folding tabletop 130;

[0050] Adjustment component 200 is located on the upper end of support component 100;

[0051] The adjustment assembly 200 includes a mounting plate 270 fixed to the upper end of the folding tabletop 130, a rotating roller 250 rotatably connected to the mounting plate 270, threaded posts 220 fixed to both ends of the rotating roller 250, a second nut 240 threadedly connected to the threaded post 220, a connecting plate 290 penetrating the threaded post 220, and a first nut 230 threadedly connected to the threaded post 220.

[0052] as well as;

[0053] Rotating component 300 is located at the front end of adjusting component 200;

[0054] The rotating assembly 300 includes a second connecting plate 350 fixed to the front end of the first connecting plate 290, a bracket 330 rotatably connected to one side of the second connecting plate 350, and a reading / writing terminal body 320 inserted into the bracket 330.

[0055] The connecting plate 290 can be limited by nuts 230 and 240. At the same time, rotating nuts 230 and 240 allows the connecting plate 290, connecting plate 250 and bracket 330 to move as needed, which facilitates clamping and limiting the reading and writing terminal body 320 of different lengths.

[0056] A base plate 110 is fixed to the lower surface of the support frame 120.

[0057] A base plate 110 is added to the lower surface of the support frame 120, which greatly improves the overall structure's resistance to tipping. The base plate 110 increases the contact area with the desktop, preventing the device from sliding or tipping over due to the weight of the reading / writing terminal body 320 or external forces during user operation.

[0058] A mounting hole 272 is provided on one side of the mounting plate 270. A bearing 271 is installed in the mounting hole 272. The bearing 271 passes through one side of the roller 250 and is rotatably connected.

[0059] Mounting holes 272 are provided on one side of the mounting plate 270, and bearings 271 are embedded in them to allow the roller 250 to rotate smoothly. The introduction of bearings 271 reduces the frictional resistance when the roller 250 rotates, making height adjustment smoother, while avoiding wear problems caused by long-term use and extending the service life of the equipment.

[0060] A mounting plate 281 is fixed to the rear end of the mounting plate 270. A motor 280 is fixed to one side of the mounting plate 281. A rotating shaft 282 is installed on the drive end of the motor 280. A gear 283 is fixed to one side of the rotating shaft 282. A gear 291 passes through one side of the rotating roller 250 and is fixed thereto. Gear 283 meshes with gear 291.

[0061] A fixing plate 281 is added to the rear end of the mounting plate 270, and a motor 280 is installed thereon. The motor drives a gear 283 via a rotating shaft 282, which in turn meshes with a gear 291 fixed on the rotating roller 250, thus achieving electric adjustment. This design allows users to adjust the height of the reading and writing terminal body 320 by controlling the motor 280, eliminating the need for manual turning and improving the convenience and accuracy of operation.

[0062] Gear 1 283 and Gear 2 291 are aligned laterally.

[0063] The transverse centers of gear 283 and gear 291 are strictly aligned to ensure smooth meshing and reduce gear wear and noise. This eliminates the possibility of uneven load distribution in gear drives, making the power transmission of motor 280 more efficient and reducing energy consumption.

[0064] A flexible gooseneck tube 260 is fixed to the upper surface of the mounting plate 270, and a lighting lamp 210 is fixed to the upper surface of the flexible gooseneck tube 260.

[0065] A flexible gooseneck tube 260 is fixed to the upper surface of the mounting plate 270, and a light 210 is installed at its top. The flexible gooseneck tube 260 can be bent freely, allowing the user to adjust the lighting angle as needed, providing a comfortable reading environment. It is suitable for low-light scenarios, such as nighttime use or low-light environments, enhancing the practicality of the device.

[0066] The connecting plate 350 is rotatably connected to the shaft 310 on one side, the shaft 310 is fixed to the bracket 330 on one side, and the bracket 330 is fixed inside the rubber pad 340. The two ends of the reading and writing terminal body 320 are respectively inserted into the rubber pad 340.

[0067] The bracket 330 has a fixed rubber pad 340 inside, into which the two ends of the reader / writer terminal body 320 are inserted. This not only securely holds the device but also cushions vibrations and impacts through the elasticity of the rubber, preventing the device from slipping or being damaged by bumps. The friction of the rubber pad 340 also ensures that the reader / writer terminal body 320 will not accidentally shift when the angle is adjusted.

[0068] The connecting plate 2 350 is rotatably connected to the rotating rod 360 on the other side. One end of the rotating rod 360 is fixed to the rotating shaft 2 310, and the other end of the rotating rod 360 is fixed to the turntable 1 370. A threaded groove 371 is opened on one side of the turntable 1 370. A connecting bracket 380 is fixed to the other end of the connecting plate 2 350. A threaded hole 381 is opened on one side of the connecting bracket 380. A threaded rod 390 is threadedly connected in the threaded hole 381. One end of the threaded rod 390 extends into the threaded groove 371 and is threadedly connected. The other end of the threaded rod 390 is fixed to the turntable 2 391.

[0069] One side of the connecting plate 350 is connected to the rotating shaft 310 via a rotating rod 360, while the other side is equipped with an adjustable locking mechanism. The turntable 370 has a threaded groove 371 that engages with the threaded rod 390. Users can adjust the tightness of the threaded rod 390 by rotating the turntable 391, thereby fixing or releasing the rotation angle of the bracket 330. This design allows for more precise angle adjustment of the reading / writing terminal body 320 and enables stable locking at any position, preventing changes in viewing angle due to external forces.

[0070] In this embodiment, when the user needs to operate the reader / writer terminal body 320, the user can first easily move the connecting plate 290, which in turn moves the front connecting plate 350 and the bracket 330 to a suitable position. At this time, the reader / writer terminal body 320 can be smoothly inserted into the bracket 330. The carefully designed anti-slip rubber pad 340 inside the bracket 330 will automatically generate a moderate clamping force to ensure that the device is firmly in place without causing surface damage.

[0071] Next, the user can finely adjust the tightness of nuts 230 and 240. These two symmetrically arranged locking mechanisms work together to create a locking effect on the threaded post 220. Nut 230 is responsible for initial positioning, while nut 240 serves as a backup against loosening. This design ensures the absolute fixation of the connecting plate 290 and effectively prevents thread loosening that may occur during long-term use. When the motor 280 is started: the rotating shaft 282 drives the gear 283 to rotate, and through perfect meshing with gear 291, power is smoothly transmitted to the roller 250. During this process, the strict lateral center alignment design of gears 283 and 291 ensures vibration-free and noise-free transmission, allowing the bracket 330 and the reading / writing terminal body 320 to be smoothly raised and lowered to any desired height.

[0072] In the angle adjustment process, when the user rotates the lever 360, this action is directly transmitted to the bracket 330 via the second rotating shaft 310, allowing the reader / writer terminal body 320 to perform stepless adjustment of its tilt angle. Particularly noteworthy is that the turntable 370 at the end of the lever 360 and the threaded rod 390 on the connecting frame 380 form a locking mechanism: rotating the turntable 391 causes the threaded rod 390 to screw into the threaded groove 371 of the turntable 370. Throughout the adjustment process, every change from height to angle is achieved through the coordinated linkage of various components, demonstrating excellent system integration and operational consistency. This achieves the effect of easily clamping and limiting reader / writer terminal bodies 320 of different lengths, while also facilitating angle and height adjustment, making the reader / writer terminal body 320 easy to use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0074] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
