Description

Technical Field

[0001] This utility model relates to the field of office equipment, and more specifically, to a large-screen folding table that is convenient for hydrological work. Background Technology

[0002] As hydrological monitoring, data analysis, and teamwork become increasingly important in scientific research and industry applications, traditional desks are no longer sufficient to meet the needs of modern hydrological work. Hydrological work often involves the use of large-screen displays to monitor data in real time, analyze hydrological trends, and assist in decision-making. Therefore, multifunctional desks with large-screen displays are gradually becoming an important part of the hydrological work environment. However, most desks on the market are currently fixed in structure and lack adaptability to large-screen devices, particularly in terms of folding, sliding, and angle adjustment. This, to some extent, limits the efficiency of office space utilization and the ease of use of equipment.

[0003] Existing desk designs often fail to accommodate the flexible deployment and storage requirements of large-screen devices. Traditional large-screen displays require significant space during use, especially in hydrological work environments where data presentation, analysis, discussion, and multi-person collaboration necessitate frequent adjustments to the screen's angle and position. However, fixed large-screen devices are inconvenient to move and occupy space when not in use, leading to a cramped office environment and hindering efficient resource management. While some existing multi-functional desks on the market offer basic features like height adjustment and rotation to accommodate ordinary monitors or small devices, they do not consider the storage and protection needs of large-screen displays, failing to allow for easy folding away when not in use, thus reducing space flexibility.

[0004] Meanwhile, hydrological work demands high real-time data accuracy, requiring stable and reliable power supply and signal connections for large-screen devices. Traditional cabling methods often appear messy and disorganized, affecting aesthetics and posing risks of cable tangling or wear. The lack of a cable management system makes cables prone to pulling or even breaking during sliding or folding, impacting normal operation and increasing daily maintenance costs. Especially in scenarios requiring frequent movement or repositioning of the display screen, improperly managed cables are susceptible to compression and breakage, leading to equipment malfunctions and unnecessary repair expenses.

[0005] The prior art discloses a foldable conference display screen (CN221488124U), including a screen body; a shell for installing and storing the screen body, the screen body being rotatably connected to the shell; and a cover plate rotatably connected to the shell for protecting the screen body. The cover plate has a buffer structure on its wall surface, the buffer structure including an elastic element and support arms. The elastic element is elastically connected to the cover plate, and two support arms are rotatably connected to the wall surface of the cover plate. The two support arms can rotate in opposite directions to support paper documents in an inward-facing position.

[0006] However, this structure cannot meet the needs of large displays used for hydrological observation, data analysis, and team collaboration. When folding and storing the displays, it is necessary to consider the fixed angle rotation and adjustment of the displays, as well as the messy wiring when connecting the large screens with cables. Utility Model Content

[0007] This invention overcomes the shortcomings of the prior art, such as the inability of the display screen to rotate and adjust at a fixed angle and the messy storage of the screen wiring, by providing a large-screen folding table that is convenient for hydrological work.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0009] A large-screen folding table for hydrological work includes a table structure, a push-pull folding mechanism, a support assembly, and a display screen disposed on the upper part of the table structure.

[0010] The table structure has a hollow interior forming a receiving cavity. After the push-pull folding mechanism and support components are connected to the table structure, they are folded and stored in the receiving cavity.

[0011] The display screen is connected to the push-pull folding mechanism, and the display screen can rotate in angle as the push-pull folding mechanism moves.

[0012] Furthermore, a fixing frame is fixedly provided on the inner surface of the table structure, and the fixing frame is I-shaped; the crossbeam of the fixing frame is provided with several snap-fit ​​holes, and the support component is connected to the fixing frame through the snap-fit ​​holes.

[0013] Furthermore, the support assembly includes a rotating fixing frame; a first concave groove frame is arranged parallel to both sides of the rotating fixing frame, a second concave groove frame is connected in the middle of the first concave groove frame, and the second concave groove frame is fixedly connected to the first concave groove frame.

[0014] Furthermore, a positioning slot is provided in the middle of the second concave groove frame;

[0015] The push-pull folding mechanism further includes a first hinge support, which has a positioning groove that is adapted to and engages with the positioning slot. The first hinge support is positioned and connected to the positioning slot through the positioning groove.

[0016] Furthermore, the push-pull folding mechanism includes multiple hinge points, as well as a second hinge support, a hinge support fixing frame, and an electric telescopic rod;

[0017] One end of the electric telescopic rod is rotatably connected to the first hinged support, and the other end is rotatably connected to the second hinged support; the hinged support fixing frame is fixed to the inner surface of the table structure; the second hinged support is locked to the hinged support fixing frame by a locking member.

[0018] Furthermore, the cavity is provided with a hidden cable channel, and a cable connected to the display screen extends inside the hidden cable channel. As the push-pull folding mechanism moves, the cable is hidden or retracted from the hidden cable channel.

[0019] Furthermore, the back of the display screen is also provided with a buffer back plate to reduce the impact force generated during sliding;

[0020] The first concave groove frame has a plurality of limiting holes on its concave surface, and the buffer back plate is fixed with limiting pins that are corresponding to and limited by the limiting holes.

[0021] Furthermore, the rotation angle of the display screen ranges from 5° to 30°.

[0022] Furthermore, the table structure has a support surface, and the surface of the support surface is provided with a mounting plate. An electrical control box for sealing and protecting internal electrical components is fixed on the surface of the mounting plate.

[0023] Preferably, the support surface is an arc-shaped support surface.

[0024] Furthermore, the bottom of the table structure is also provided with support legs for supporting the table and adjusting its height, and the support legs are provided with screws that cooperate with and connect to the bottom of the table structure.

[0025] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0026] ① Saves space and optimizes display screen usage. This large-screen folding table, through its push-pull folding mechanism and support components, allows the display screen to be flexibly stored within the table's internal cavity, solving the problem of fixed large screens occupying office space. The display screen's angle can be flexibly adjusted via the push-pull folding mechanism to adapt to different work needs, greatly improving space utilization and making it suitable for scenarios requiring flexible deployment of large screens, such as hydrological work.

[0027] ② Stable structure, enhancing operational safety. The table structure features multiple limiting and positioning designs, including a fixing frame, snap-fit ​​holes, limiting holes, and limiting pins, which provide reliable limiting and locking when the display screen is pushed, pulled, rotated, or its angle adjusted, preventing accidental movement or shaking during use. At the same time, the buffer backplate on the back of the display screen reduces the impact force generated during sliding, effectively protecting the display screen and improving operational safety.

[0043] Example 1

[0044] like Figure 1-9 The present embodiment discloses a large-screen folding table that is convenient for hydrological work, including a table body structure 1, a push-pull folding mechanism 2, a support component 3, and a display screen 4 disposed on the upper part of the table body structure;

[0045] The table structure 1 has a hollow interior forming a receiving cavity 101. The push-pull folding mechanism 2 and the support component 3 are connected to the table structure 1 and folded into the receiving cavity 101. The display screen 4 is fixedly connected to the push-pull folding mechanism 2, and the display screen 4 can rotate with the movement of the push-pull folding mechanism 2. The rotation angle of the display screen 4 is in the range of 5°-30°.

[0046] By incorporating a hollow receiving cavity 101 within the table structure 1, the push-pull folding mechanism 2 and support component 3 can be folded and stored within the receiving cavity 101 when not in use, effectively hiding the large-screen display device and saving office space. When needed, the display screen 4 can be adjusted in angle via the push-pull folding mechanism 2 to adapt to different usage scenarios. This design is particularly suitable for hydrological monitoring work, ensuring flexible deployment of the display screen 4 while making the workspace neater and more efficient. During operation, the display screen 4 displays text and graphics related to hydrological work, and its angle can be adjusted according to different scenarios. For example, when conducting collaborative hydrological data analysis, the angle can be adjusted to 15°.

[0047] A fixed frame 102, shaped like an I-beam, is fixed to the inner surface of the table structure 1. Several snap-fit ​​holes 1011 are provided at the crossbeam of the fixed frame 102, through which the support component 3 is securely connected to the fixed frame 102. The I-beam structure of the fixed frame 102 provides strong bending resistance and load-bearing capacity, effectively improving the stability and load-bearing capacity of the table during use and preventing wobbling or deformation. The precise snap-fit ​​connection between the support component 3 and the fixed frame 102 effectively prevents loosening and extends service life. During repeated folding and unfolding, fatigue damage is less likely, ensuring long-term stability. The folded table occupies little space, making it suitable for use in limited spaces.

[0048] Support component 3 includes a rotating fixing frame 301;

[0049] The rotating fixing frame 301 has two parallel concave slot frames 3011 on both sides, and a second concave slot frame 3012 is connected in the middle of the first concave slot frame 3011. The second concave slot frame 3012 is fixedly connected to the first concave slot frame 3011. The second concave slot frame 3012 has a positioning slot 3013 in the middle. The push-pull folding mechanism 2 also includes a first hinge support 201. The first hinge support 201 has a positioning groove 2011 that is adapted to engage with the positioning slot 3013. The first hinge support 201 is positioned and connected to the positioning slot 3013 through the positioning groove 2011.

[0050] The push-pull folding mechanism 2 includes multiple hinge points, a second hinge support 202, a hinge support fixing frame 203, and an electric telescopic rod 204. One end of the electric telescopic rod 204 is rotatably connected to the first hinge support 201, and the other end is rotatably connected to the second hinge support 202. The hinge support fixing frame 203 is fixed to the inner surface of the table structure 1. The second hinge support 202 is locked to the hinge support fixing frame 203 by a locking device. The telescopic end of the electric telescopic rod 204 is driven by a motor. The end of the telescopic end is equipped with a limiting mechanism, which automatically stops when the telescopic rod reaches the top, ensuring that the motor does not burn out. At the same time, the telescopic rod has a built-in mechanical locking structure, which can stop at any position. The motor of the electric telescopic rod 204 is connected to an external battery or power source. An electrical control box is installed inside the receiving cavity 101 of the desktop structure 1. The control box is electrically connected to the motor of the electric telescopic rod 204. The travel of the telescopic rod is 10mm-1000mm, and the thrust it can generate is 100N-3500N, sufficient to drive the angle adjustment of the display screen 4. When the desktop is fully extended, the second hinge support 202 is connected to the hinge support fixing frame 203 via a locking device, ensuring the stability of the push-pull folding mechanism and preventing instability caused by loosening during use.

[0051] Example 2

[0052] like Figure 1-9 As described above, this embodiment discloses a large-screen folding table that is convenient for hydrological work. The solution is similar to that of embodiment 1, except that:

[0053] The back of the display screen 4 is also provided with a buffer back plate 401 to reduce the impact force generated during sliding;

[0054] The first concave groove frame 3011 has several limiting holes 3014 on its concave surface. A limiting pin 4011, corresponding to and connected to the limiting holes 3014, is fixed on the buffer back plate 401. The limiting pin 4011 is positioned by inserting into the limiting hole 3014. When the limiting pin 4011 is fully embedded in the limiting hole 3014, the component is fixed in a predetermined position, restricting the free movement of the limiting pin 4011. When the limiting pin 4011 and the limiting hole 3014 are used together, precise positioning of the mechanical component can be achieved, ensuring that the component will not exceed the predetermined range of motion during use. The bottom of the limiting pin 4011 is fixed to the buffer back plate 401, and its position is ensured to be fixed by welding, threading, or snap-fitting.

[0055] Example 3

[0056] like Figure 1-9 As described above, this embodiment discloses a large-screen folding table that is convenient for hydrological work. The solution is similar to that of embodiment 1, except that:

[0057] The receiving cavity 101 is equipped with a concealed cable tray, through which cables connected to the display screen extend. As the push-pull folding mechanism 2 moves, the cables are concealed or retracted within the concealed cable tray. By providing a concealed cable tray within the receiving cavity 101, the cables can be hidden or retracted with the movement of the push-pull folding mechanism 2, avoiding problems such as tangling, pulling, or wear caused by exposed cables. This cable management method ensures the neatness and safety of electrical connections, effectively extends the service life of cables, and reduces the maintenance costs of the electrical system.

[0058] The table structure has a support surface 103, which is an arc-shaped support surface. A mounting plate 104 is provided on the surface of the support surface 103, and an electrical control box 105 for sealing and protecting the internal electrical components is fixed on the surface of the mounting plate 104. The electrical control box 105 provides comprehensive protection for the internal electrical components, effectively preventing dust and moisture, and ensuring the stable operation of the electrical system in complex hydrological environments.

[0059] The bottom of the table structure 1 is also equipped with support feet 106 for supporting the table and adjusting its height. Support feet 106 have screws that mate with the bottom of the table structure 1. The inner wall of the bottom of the table structure 1 has threads, and the support feet 106 have screw structures that match these threads. The height of the support feet is adjusted by rotating the threads, thereby adjusting the height of the table structure 1. The support surface 103 inside the table structure 1 provides a stable foundation for the mounting plate 104, and a sealed electrical control box 105 is fixed to the surface of the mounting plate. Furthermore, compared to a right-angled corner support surface, the support surface 103 provides a smooth contact surface for internal cable routing, reducing friction during repeated operation of the push-pull folding mechanism 2. The support surface 103 is also more aesthetically pleasing.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
