Abstract
Description
Technical Field
[0001] This invention belongs to the field of mechanical support technology, specifically relating to an engineering management early warning display device. Background Technology
[0002] In the complex and ever-changing engineering construction environment, project scale continues to expand, construction difficulty continues to increase, and various risk factors also increase accordingly. Engineering management early warning display devices have emerged to address this need. They can collect, integrate, and analyze various data and information during the engineering construction process in real time, and promptly issue early warning signals to management personnel.
[0003] In the actual installation and application of engineering management early warning display devices, the uprights, as the load-bearing structure supporting various installation components, directly affect installation efficiency and stability through their connection and height adjustment methods. In existing technologies, various installation components are typically fixed to the uprights using clamps or fixed bases, and their height is adjusted to meet visibility or detection requirements. However, this approach has several shortcomings in practical operation:
[0004] When installing large components, such as displays for project management data, the weight and high placement of these devices on poles often require ladders or other climbing tools. Positioning and securing them is difficult for a single person and usually requires multiple people, increasing labor costs and extending the installation time. Furthermore, if the installation height does not meet requirements, the fixed structure must be disassembled and readjusted, a cumbersome and inefficient process.
[0005] While some support structures with height adjustment capabilities exist, such as those using threaded rods, hydraulic cylinders, or electric actuators, their complex structures, high manufacturing costs, and insufficient stability and adaptability in outdoor engineering environments, coupled with inflexible and inconvenient adjustment processes, make them unsuitable for modern applications. Therefore, there is an urgent need in this field for a simple, easy-to-operate, quickly installable, and reliably adjustable support structure for display devices, in order to improve the practicality and installation efficiency of engineering management early warning display devices. Summary of the Invention
[0006] The purpose of this invention is to provide an engineering management early warning display device to solve the problems mentioned in the background art, such as the difficulty in installing the display screen on the pole, the cumbersome height adjustment, the need for multiple operators, and the lack of stability.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an engineering management early warning display device, the display device comprising a pole, a height adjustment mechanism, and mounting components;
[0008] The height adjustment mechanism includes a height adjustment section and a docking assembly;
[0009] The height adjustment part is movably sleeved on the upright and rotatably connected to the rear surface of the mounting part;
[0010] The docking assembly includes a snap-fit component and an adjustment component;
[0011] The latching member is movably disposed horizontally within the height adjustment section, with one end of the latching member extending into the inner side of the height adjustment section; the bottom end of the adjusting member is movably connected to one end of the latching member, the latching member moves horizontally under the swing of the adjusting member, the top of the adjusting member extends upward at an angle, and the top end of the adjusting member extends through to the outside of the height adjustment section;
[0012] The top of the adjusting member abuts against the tilted mounting member; the mounting member is located on the front surface of the upright.
[0013] As a preferred technical solution of the present invention, the height adjustment part includes a connecting sleeve and an arc sleeve;
[0014] The connecting sleeve has an opening that fits over the outside of the upright, and an inner groove is formed inside the connecting sleeve facing the mounting component. A slot is also formed on the side of the connecting sleeve that communicates with the inner groove. A square groove is also formed above the inner groove. An inclined surface is also formed on the outer surface of the connecting sleeve, which is located above the square groove.
[0015] The end of the snap-fit component extends through the slot into the interior of the connecting sleeve, while the middle of the snap-fit component remains inside the inner groove; the top of the adjusting component is located within the square groove, while the top of the adjusting component extends obliquely through to the exterior of the connecting sleeve.
[0016] The arc sleeve is placed inside the opening of the connecting sleeve. The connecting sleeve is rotatably connected to the outer wall of one end of the arc sleeve, while the connecting sleeve and the other end of the arc sleeve are in a planar overlapping shape. A threaded sleeve is fixed at the outer wall of the overlapping position of the two, and a bolt is screwed into the threaded sleeve.
[0017] As a preferred technical solution of the present invention, the snap-fit component includes a mounting block, a snap plate, a connecting rod, and an adjusting spring;
[0018] The mounting block is installed in the slot near the mounting part of the connecting sleeve. One end of the mounting block extends into the inner groove. A through hole is also provided at one end of the mounting block. In order to ensure a stable connection between the connecting sleeve and the upright, multiple mounting blocks and clamping plates need to be provided.
[0019] The surface of the upright is provided with slots at equal intervals, and each slot corresponds to a card plate;
[0020] The card plate passes horizontally through the slot of the connecting sleeve away from the mounting part and is inserted into the slot. The top of the end of the card plate that extends to the outside of the connecting sleeve is inclined. When adjusting the height later, this inclination can ensure that the card plate retracts normally and avoids the problem of jamming when lifting it into the mounting part.
[0021] Multiple connecting rods are provided. The connecting rods are located between the mounting block and the card plate, with one end of the connecting rod fixed to the end face of the card plate and the other end movably inserted into the through hole of the mounting block.
[0022] The adjusting spring is sleeved on the connecting rod in the middle position. The two ends of the adjusting spring are fixedly connected to the mounting block and the clamping plate, respectively. In actual use, the mounting block, adjusting spring, and clamping plate can be connected by spot welding to make them a whole, or they can be sleeved on all the connecting rods. The connecting rod sleeved in the middle position is just one of many implementation methods. As long as the adjusting spring can provide the rebound force to pop the clamping plate out, it is fine. The number of adjusting springs mainly affects the rebound speed of the clamping plate. Therefore, the clamping plate can be added according to actual needs. When adding, it should follow the symmetrical distribution to ensure that the rebound force is evenly applied to the clamping plate.
[0023] The card plate has symmetrical moving slots on both sides, which are connected to the adjusting component.
[0024] As a preferred technical solution of the present invention, the adjusting member includes a connecting rod, a pressing part, and a moving frame;
[0025] The connecting rod is inclinedly arranged in the square groove, and the bottom of the connecting rod extends into the inner groove. A shaft fixed to the inner wall of the square groove passes through the middle of the connecting rod, and the connecting rod swings around the shaft.
[0026] The top of the pressing part is located outside the inclined surface and abuts against the inclined mounting part, while the bottom of the pressing part is connected to the top of the connecting rod.
[0027] The connecting rod swings as it moves diagonally downward in the pressing part.
[0028] The movable frame is in the shape of an inverted "U" and is fitted on the outside of the card plate. The inner side of the movable frame is fixed with a vertical groove that fits into the movable slot. When the card plate completely penetrates the slot, the vertical groove abuts against the inner wall of one end of the movable slot.
[0029] As a preferred technical solution of the present invention, the pressing part includes a pressing plate, a diagonal bar, a limiting plate, and a return spring;
[0030] The pressing plate is located on the outside of the inclined surface, and the inclination angle of the pressing plate is greater than that of the inclined surface. The bottom of the pressing plate is rotatably connected to the inclined surface.
[0031] The inclined rod is located below the pressing plate, and the two are arranged perpendicular to each other. The bottom of the inclined rod passes through the inclined surface into the square groove, and an inclined hole extending towards the top of the inclined rod is also provided on the bottom end surface of the inclined rod.
[0032] The limiting plate is fixed to the inner wall of the square groove. The surface of the limiting plate is fixed with a correction column with the same inclination as the inclined bar. The correction column is movably inserted into the inclined hole of the inclined bar. When the inclined bar moves down, it will squeeze the return spring. The rebound force generated after the return spring is compressed can return the inclined bar to its original position after the mounting part separates from the inclined surface.
[0033] The reset spring is sleeved on the correction column, and the two ends of the reset spring abut against the inclined rod and the limiting plate, respectively.
[0034] In order to ensure that the inclined rod can compress the return spring when it moves toward the square groove, the return spring and the inclined rod are arranged collinearly, while the limiting plate is arranged perpendicular to the inclined rod.
[0035] As a preferred technical solution of the present invention, the top end of the connecting rod is provided with an end groove, and the bottom side of the inclined rod is fixed with a protruding post that penetrates into the end groove.
[0036] As a preferred technical solution of the present invention, the surface of the movable frame is provided with a vertical groove, and the bottom inner side of the connecting rod is fixed with a column-shaped body similar to the protruding post, which is movably inserted into the vertical groove; when the connecting rod swings clockwise, the path of the bottom of the connecting rod is arc-shaped. In order to drive the movable frame to move, the setting of the vertical groove can ensure that the column-shaped body on the bottom inner side of the connecting rod always moves the movable frame through the vertical groove.
[0037] As a preferred technical solution of the present invention, the mounting component includes a display screen. A rotating shaft that is rotatably connected to the connecting sleeve is mounted on the rear surface of the display screen, so that the display screen can rotate through the rotating shaft and press down the extrusion plate. A handle is also fixed on the rear surface of the display screen, which can be used as a point of force when pulling, disassembling, or adjusting the display screen. A support frame is also mounted on the bottom end of the connecting sleeve. When the display screen is in a vertical state, the bottom end of the display screen rests on the support frame. Conversely, when the display screen rotates, it separates from the support frame. The rotated display screen does not contact the upright, avoiding the phenomenon of being unable to adjust or disassemble due to mutual contact.
[0038] As a preferred technical solution of the present invention, the top of the pole is provided with an early warning module, which is connected to the display screen through a transmission harness;
[0039] The early warning module includes a dust sensor installed on the top surface of the pole and cameras installed on both sides of the top of the pole. The cameras and dust sensor are connected to the display screen via a transmission harness. In use, the dust sensor monitors the dust content in the air, and the cameras monitor the speed of passing vehicles and other conditions. After processing by the control box, the monitoring results are displayed on the display screen.
[0040] As a preferred technical solution of the present invention, a control box is also provided at the bottom of the display screen. The control box is mounted on the pole and is connected to the warning module and the display screen through a transmission cable harness.
[0041] Compared with the prior art, the beneficial effects of the present invention are:
[0042] In this invention, a dedicated height adjustment mechanism is provided after the mounting component. This mechanism features rapid installation, height adjustment, and stable support, significantly improving the support structure of the engineering management early warning display device.
[0043] Improved ease of installation: The height adjustment mechanism uses a snap-fit connector that engages with a slot on the upright, combined with the linkage design of the adjustment component, to achieve quick locking and releasing. During installation, only one person is needed to operate the mechanism; simply tilting the installation component triggers the adjustment mechanism, causing the snap-fit connector to retract, thus freely adjusting the height of the height adjustment unit. Once in place, it automatically locks in place, eliminating the need for disassembly or additional tools, significantly simplifying the installation process.
[0044] Flexible and reliable height adjustment: The height can be adjusted steplessly or in steps through mechanical linkage. The adjustment process is smooth and the locking is reliable, avoiding the problem of repeated disassembly required by traditional clamp structures. This effectively shortens the adjustment time and adapts to different on-site installation needs.
[0045] High structural stability: The height adjustment mechanism uses a connecting sleeve and an arc sleeve in combination and is fastened with bolts to ensure a firm connection with the upright and prevent swaying; the support frame further enhances the support stability of the display screen in the vertical position. The overall structure is simple, durable and suitable for complex engineering environments.
[0046] High versatility and adaptability: This height adjustment mechanism is not only suitable for engineering early warning display devices, but can also be extended to other display or monitoring equipment that requires pole installation. It has good versatility, and the mechanical structure is not easily affected by the environment, so it has high reliability. Attached Figure Description

[0075] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0076] Please see Figures 1 to 9 The present invention provides a technical solution: an engineering management early warning display device, the display device including a pole 100, a height adjustment mechanism, and mounting components;
[0077] The height adjustment mechanism includes a height adjustment section 200 and a docking assembly;
[0078] The height adjustment part 200 is movably sleeved on the upright 100 and rotatably connected to the rear surface of the mounting part;
[0079] The docking components include snap-fit parts and adjustment parts;
[0080] The latching member is movably disposed horizontally within the height adjustment section 200, with one end of the latching member extending into the inner side of the height adjustment section 200; the bottom end of the adjusting member is movably connected to one end of the latching member, the latching member moves horizontally under the swing of the adjusting member, the top of the adjusting member extends upward at an angle, and the top end of the adjusting member extends through to the outside of the height adjustment section 200.
[0081] The top of the adjusting component abuts against the tilted mounting component; the mounting component is located on the front surface of the upright 100.
[0082] In this embodiment, refer to Figure 4 , Figure 7 , Figure 8 The height adjustment part 200 includes a connecting sleeve 201 and an arc sleeve 202;
[0083] The connecting sleeve 201 has an opening that fits over the outside of the upright 100. The connecting sleeve 201 has an inner groove 201b inside facing the mounting component. The side of the connecting sleeve 201 also has a slot 201d that communicates with the inner groove 201b. A square groove 201a is also formed above the inner groove 201b. The outer surface of the connecting sleeve 201 also has a beveled surface 201c, which is located above the square groove 201a.
[0084] The end of the snap-fit component extends through the slot 201d into the interior of the connecting sleeve 201, while the middle part of the snap-fit component is always inside the inner groove 201b; the top of the adjusting component is inside the square groove 201a, while the top of the adjusting component extends obliquely into the exterior of the connecting sleeve 201.
[0085] The arc sleeve 202 is placed inside the opening of the connecting sleeve 201. The connecting sleeve 201 and the outer wall of one end of the arc sleeve 202 are rotatably connected, while the other end of the connecting sleeve 201 and the arc sleeve 202 are in a planar overlapping state. At least two threaded sleeves 203 are fixed at the upper and lower ends of the outer wall at the overlapping position. A bolt is screwed into the threaded sleeve 203. After the installation part reaches the specified height, the bolt is tightened. One end of the bolt is limited to the end of one of the threaded sleeves 203, while the other threaded sleeve 203 is close to the adjacent threaded sleeve 203 under the connection of the bolt, so that the connecting sleeve 201 and the arc sleeve 202 are tightly held on the upright 100, avoiding slight left and right swinging between the connecting sleeve 201 and the upright 100. When disassembling later, it is also necessary to first rotate the bolt to change the connecting sleeve 201 and the arc sleeve 202 and the upright 100 from the abutting state to the movable but not separated state. Then the installation part is tilted for subsequent disassembly work.
[0086] In this embodiment, refer to Figure 3 , Figure 4 , Figure 5 The snap-fit component includes a mounting block 301, a snap plate 302, a connecting rod 303, and an adjusting spring 304;
[0087] The mounting block 301 is installed in the slot 201d of the connecting sleeve 201 near the mounting part. One end of the mounting block 301 extends into the inner groove 201b. A through hole is also provided at one end of the mounting block 301. In order to ensure a stable connection between the connecting sleeve 201 and the upright 100, multiple mounting blocks 301 and clamping plates 302 need to be provided. Four are provided in the figure.
[0088] The surface of the upright 100 is provided with slots 100a at equal intervals, and each slot 100a corresponds to a card plate 302.
[0089] The card plate 302 horizontally penetrates the slot 201d of the connecting sleeve 201 away from the mounting part and is inserted into the slot 100a. The top of the end of the card plate 302 that penetrates to the outside of the connecting sleeve 201 is inclined. When adjusting the height later, this inclination can ensure that the card plate 302 retracts normally and avoids the problem of jamming when it is lifted into the mounting part.
[0090] Multiple connecting rods 303 are provided. Figure 5 In the middle, three connecting rods 303 are set. The number of connecting rods 303 varies according to the width of the mounting block 301 and the clamping plate 302. It can also be adjusted according to the actual support strength. It will not be described in detail here. The connecting rod 303 is located between the mounting block 301 and the clamping plate 302. One end of the connecting rod 303 is fixed to the end face of the clamping plate 302, and the other end is movably inserted into the through hole of the mounting block 301.
[0091] The adjusting spring 304 is sleeved on the connecting rod 303 in the middle position. The two ends of the adjusting spring 304 are fixedly connected to the mounting block 301 and the clamping plate 302 respectively. In actual use, the mounting block 301, adjusting spring 304 and clamping plate 302 can be connected by spot welding to make them a whole, or they can be sleeved on all the connecting rods 303. The connecting rod 303 in the middle position is just one of many implementation methods. As long as the adjusting spring 304 can provide the rebound force to pop out the clamping plate 302, it is fine. The number of adjusting springs 304 mainly affects the rebound speed of the clamping plate 302. Therefore, the clamping plate 302 can be added according to actual needs. When adding, it should follow the symmetrical distribution to ensure that the rebound force is evenly applied to the clamping plate 302.
[0092] The card plate 302 has symmetrical moving grooves 302a on both sides, and the moving grooves 302a are connected to the adjusting component.
[0093] In this embodiment, refer to Figure 4 , Figure 5 , Figure 6 The adjusting component includes a connecting rod 401, a pressing part, and a moving frame 405;
[0094] The connecting rod 401 is inclinedly arranged in the square groove 201a. The bottom of the connecting rod 401 extends into the inner groove 201b. A shaft fixed to the inner wall of the square groove 201a passes through the middle of the connecting rod 401. The connecting rod 401 swings around the shaft as a whole.
[0095] The top of the pressing part is located outside the inclined surface 201c and abuts against the inclined mounting part, while the bottom of the pressing part is connected to the top of the connecting rod 401.
[0096] Among them, when the connecting rod 401 moves diagonally downward in the pressing part, it makes a swinging motion;
[0097] The movable frame 405 is in the shape of an inverted "U" and is fitted on the outside of the card plate 302. The inner side of the movable frame 405 is fixed with a vertical groove 405a that is inserted into the movable slot 302a. When the card plate 302 completely penetrates the slot 201d, the vertical groove 405a abuts against the inner wall of one end of the movable slot 302a.
[0098] In this embodiment, refer to Figure 4 , Figure 5 , Figure 6 , Figure 9 The pressing part includes a pressing plate 402, a diagonal bar 403, a limiting plate 404, and a return spring 406;
[0099] The pressing plate 402 is located on the outside of the inclined surface 201c. The inclination angle of the pressing plate 402 is greater than that of the inclined surface 201c. That is, the pressing plate 402 is located between the inclined surface 201c and the mounting part, and the bottom of the pressing plate 402 is rotatably connected to the inclined surface 201c. Therefore, when the mounting part rotates, it will press the pressing plate 402. At this time, the top of the pressing plate 402 moves downward and presses the inclined rod 403. The pressing plate 402 is mainly supported by the inclined rod 403.
[0100] The inclined rod 403 is located below the pressing plate 402, and the bottom of the inclined rod 403 passes through the inclined surface 201c to the square groove 201a. An inclined hole extending towards the top of itself is also provided on the bottom end surface of the inclined rod 403.
[0101] The limiting plate 404 is fixed to the inner wall of the square groove 201a. The surface of the limiting plate 404 is fixed with a correction column 407 with the same inclination as the inclined rod 403. The correction column 407 is movably inserted into the inclined hole of the inclined rod 403. When the inclined rod 403 moves down, it will squeeze the return spring 406. The rebound force generated by the compression of the return spring 406 can return the inclined rod 403 to its original position after the mounting part is separated from the inclined surface 201c. The elastic force of the return spring 406 can lift the pressing plate 402 and the inclined rod 403 that are not squeezed by the mounting part.
[0102] The return spring 406 is sleeved on the correction column 407, and the two ends of the return spring 406 abut against the inclined rod 403 and the limiting plate 404 respectively.
[0103] In order to ensure that the inclined rod 403 can compress the return spring 406 when it moves toward the square groove 201a, the return spring 406 and the inclined rod 403 are arranged collinearly, while the limiting plate 404 is arranged perpendicular to the inclined rod 403, so as to provide the best force point for the return spring 406.
[0104] In this embodiment, refer to Figure 9The top end of the connecting rod 401 is provided with an end groove 401a, and the bottom side of the inclined rod 403 is fixed with a protrusion 403a that penetrates into the end groove 401a. Figure 9 When the solid arrow moves downward, it will cause the connecting rod 401 to rotate clockwise, that is, rotate in the direction indicated by the dashed arrow. The end slot 401a ensures that the inclined rod 403 can always drive the connecting rod 401 to rotate when it moves downward, thus avoiding the occurrence of movement obstacles.
[0105] In this embodiment, refer to Figure 5 The surface of the movable frame 405 is provided with a vertical groove 405a, and the bottom inner side of the connecting rod 401 is fixed with a columnar body that is the same as the protruding post 403a. The columnar body is movably inserted into the vertical groove 405a. When the connecting rod 401 swings clockwise, the path of the bottom of the connecting rod 401 is arc-shaped. In order to drive the movable frame 405 to move, the setting of the vertical groove 405a can ensure that the columnar body on the bottom inner side of the connecting rod 401 always moves the movable frame 405 through the vertical groove 405a.
[0106] In this embodiment, refer to Figure 4 and Figure 7 The mounting components include a display screen 102. A rotating shaft 102b, which is rotatably connected to the connecting sleeve 201, is mounted on the rear surface of the display screen 102. Therefore, the display screen 102 can rotate through the rotating shaft 102b and press down the pressing plate 402. A handle 102a is also fixed on the rear surface of the display screen 102. When pulling, disassembling, or adjusting the display screen 102, the handle 102a can be used as a point of force. A support frame 500 is also mounted on the bottom end of the connecting sleeve 201. When the display screen 102 is in a vertical state, the bottom end of the display screen 102 is supported on the support frame 500. Conversely, when the display screen 102 rotates, it separates from the support frame 500. The rotated display screen 102 does not contact the upright 100, avoiding the phenomenon of being unable to adjust or disassemble due to mutual contact.
[0107] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 The top of the pole 100 is equipped with an early warning module, which is connected to the display screen 102 via a transmission harness;
[0108] The early warning module includes a dust sensor 104 installed on the top surface of the pole 100 and cameras 103 installed on both sides of the top of the pole 100. The cameras 103 and the dust sensor 104 are connected to the display screen 102 via a transmission harness. In use, the dust sensor 104 monitors the dust content in the air, and the cameras 103 can monitor the speed of passing vehicles and other conditions. After processing by the control box 101, the monitoring results are displayed on the display screen 102. In actual use, various sensors, such as PM2.5 and TSP, can be added to provide comprehensive early warning display for the project.
[0109] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 A control box 101 is also provided at the bottom of the display screen 102. The control box 101 is installed on the pole 100 and is connected to the warning module and the display screen 102 through a transmission cable harness. The control box 101 serves as the main control terminal, used to house the control module of the warning module, and to manage, maintain, and debug the warning module and the display screen 102. This is existing technology and will not be described in detail here. In order to facilitate maintenance and management, the control box 101 is generally set at a low height and can be installed without external lifting devices or ladders. Therefore, it can be fixed to the pole 100 by means of clamps. If the height of the control box 101 is high, it can also be installed in the same way as the display screen 102.
[0110] The following explains the assembly and disassembly principles of the engineering management early warning display device:
[0111] First, put the connecting sleeve 201 on the upright 100, then rotate the arc sleeve 202, and then screw the bolt into the two threaded sleeves 203, so that the arc sleeve 202 is connected to the connecting sleeve 201, but do not hold the upright 100 tightly. In order to avoid the protruding clamping plate 302 from abutting against the upright 100, the display screen 102 needs to be rotated so that the display screen 102 is in contact with the inclined surface 201c. It should be noted here that the entire height adjustment part 200 and the upright 100 can be installed standing up without the need for lifting equipment or ladders.
[0112] After the height adjustment unit 200 and the upright 100 are completed, during the height adjustment process, the operator pulls the handle 102a of the display screen 102 and tilts the display screen 102. The rear surface of the display screen 102 will press against the pressing plate 402. At this time, the pressing plate 402 rotates downward as a whole. The downward-rotating pressing plate 402 squeezes the inclined rod 403 to move downward. The protrusion 403a at the bottom of the inclined rod 403 slides in the end groove 401a of the connecting rod 401, causing the connecting rod 401 to swing clockwise around the axis. When the connecting rod 401 swings, the columnar part on the inner side of its bottom... The body moves within the vertical groove 405a, causing the moving frame 405 and the toggle block 405b to move horizontally. The toggle block 405b causes the moving groove 302a to move, thereby pulling the card plate 302 back from the card slot 100a of the upright 100 and releasing the engagement. At this time, the height adjustment part 200 can slide up and down quickly along the upright 100 to adjust the height of the display screen 102. This can also be applied to the later disassembly. After the display screen 102 is slid to a position that is easy to disassemble, the connecting sleeve 201 and the arc sleeve 202 can be rotated open to achieve disassembly.
[0113] After adjustment, the display screen 102 is released and returns to its original position under the action of the reset spring 406. The inclined rod 403 moves upward and lifts the pressing plate 402, causing the connecting rod 401 to swing counterclockwise, and the moving frame 405 is reset accordingly. The locking plate 302 is re-locked into the locking slot 100a under the action of the rebound force of the adjusting spring 304, thus achieving fixation. Throughout the process, the connecting rod 303 and the mounting block 301 ensure the stable movement of the locking parts. When it is necessary to make a slight upward adjustment to the height of the display screen 102 later, the display screen 102 is pulled vertically. At this time, each locking plate 302 moves out of the locking slot 100a through the inclined surface at one end and locks into the previous locking slot 100a when the display screen 102 is pulled upward.
[0114] The early warning module continuously monitors environmental data, such as dust content and vehicle speed, and transmits the data to the control box 101 for processing via a transmission harness. Finally, the early warning information is displayed on the display screen 102. The control box 101 is installed at the bottom of the pole 100 for easy maintenance and management. The device achieves convenient height and angle adjustment through mechanical linkage to ensure clear display of early warning information.
