Description

Technical Field

[0001] This utility model relates to the field of engineering construction management technology, specifically to an engineering construction management information device. Background Technology

[0002] In the process of engineering construction management, construction management information devices (such as terminal equipment that integrates construction progress display, safety specification query and data entry functions) have become key equipment to ensure construction efficiency and safety. They need to be adaptable to diverse construction scenarios such as open-air operations, enclosed spaces, and temporary office areas, and also need to meet the viewing and operation needs of operators of different heights.

[0003] In terms of angle adjustment, most existing construction management information devices adopt a bolt-fixed structure. Adjustment requires the use of tools such as wrenches to remove the bolts, and then tighten them again after adjustment. This operation is cumbersome and the adjustment accuracy is low, making it difficult to quickly adapt to the needs of scenarios such as strong light reflection and multi-person collaborative viewing. Some devices that use a simple rotating structure lack a reliable limit locking mechanism. After adjustment, the angle is easily offset by construction vibration, affecting the stability of use.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for an angle adjustment mechanism that is simple in structure, easy to operate, and highly stable, so as to improve the adaptability and practicality of construction management information devices in complex construction scenarios. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engineering construction management information device, comprising a rotating assembly on the rear side of the outer wall of the main body of the device, the rotating assembly including a connecting rod, a rotating rod on the left side of the outer wall of the connecting rod, a mounting plate fixedly connected to the end of the rotating rod away from the connecting rod, a spring on the left side of the outer wall of the mounting plate, a first limiting block outside the rotating rod, the side of the outer wall of the mounting plate away from the spring being fixedly connected to the first limiting block, a connecting cylinder on the side of the spring away from the mounting plate, a second limiting block on the inner wall of the connecting cylinder corresponding to the first limiting block, and a support block on the left side of the outer wall of the connecting cylinder.

[0007] Preferably, the rotating rod is rotatably connected to the connecting cylinder, and a lead screw is fixedly connected to the bottom of the outer wall of the support block.

[0008] Preferably, a gear is sleeved on the outer wall of the lead screw, and a worm gear is meshed with the outer wall of the gear.

[0009] Preferably, a rocker arm is provided at the front end of the outer wall of the worm gear, and a mounting box is rotatably connected to the rear side of the outer wall of the worm gear.

[0010] Preferably, the mounting box has track rods on both the top and bottom sides of its outer wall, and a base is fixedly connected to the bottom of the outer wall of the track rods.

[0011] Preferably, a locking block is fixedly connected to the inner wall of the track rod, and a track groove is formed on the outer wall of the lead screw at the location corresponding to the locking block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model adopts an angle adjustment method of press-to-unlock, rotation-to-adjust, and spring-reset-lock. No tools are required. The operator can quickly release the limit by manually pressing the connecting rod. After adjustment, releasing it will automatically lock the position. The operation process is simplified, which greatly improves the efficiency of angle adjustment. It is especially suitable for the need for frequent viewing angle adjustment in construction scenarios. The spring-driven first limit block and second limit block meshing structure fit tightly after locking, which can effectively resist the angle deviation caused by construction vibration and solve the problem of poor stability of existing simple rotation structures. At the same time, the uniform distribution design of the first limit block and the second limit block can realize multi-angle graded adjustment to meet the viewing angle needs of different scenarios such as strong light reflection avoidance and multi-person collaborative viewing. 2. Height adjustment is achieved through a mechanical transmission structure using a rocker arm, worm gear, gear, and lead screw. Compared to hydraulic lifting structures, this completely avoids oil leakage and dust jamming issues. Compared to electric lifting structures, no additional power supply is required, reducing equipment costs and maintenance difficulty. It also offers greater flexibility for adapting to temporary construction scenarios. The locking blocks on the inner wall of the track rod and the track groove on the outer wall of the lead screw form a guide and limiting mechanism, which not only prevents circumferential rotation of the lead screw during lifting but also guides its axial movement, effectively preventing the main body of the device from swaying or tilting during lifting and improving the stability and safety of height adjustment. In addition, the meshing structure of the worm gear and gear has a self-locking characteristic, allowing it to lock automatically after adjustment to the target height without the need for an additional locking mechanism, further simplifying the structural design.

[0016] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: an engineering construction management information device, including a device body 1) and a rotating assembly. The rotating assembly is provided on the rear side of the outer wall of the device body 1. The rotating assembly includes a connecting rod 201, a rotating rod 202 is provided on the left side of the outer wall of the connecting rod 201, and a mounting plate 203 is fixedly connected to the end of the rotating rod 202 away from the connecting rod 201. A spring 204 is provided on the left side of the outer wall of the mounting plate 203. A first limiting block 205 is provided outside the rotating rod 202. The side of the outer wall of the mounting plate 203 away from the spring 204 is fixedly connected to the first limiting block 205.

By adopting a press-to-unlock, rotation-to-adjust, and spring 204-to-lock angle adjustment method, no tools are needed. The operator can quickly release the limit by manually pressing the connecting rod 201, and automatically lock it after adjustment. The operation process is simplified, greatly improving the efficiency of angle adjustment. It is especially suitable for the need for frequent viewing angle adjustment in construction scenarios. The meshing structure of the first limit block 205 and the second limit block 207 driven by the spring 204 fits tightly after locking, which can effectively resist the angle displacement caused by construction vibration and solve the problem of poor stability of the existing simple rotation structure. At the same time, the uniform distribution design of the first limit block 205 and the second limit block 207 can realize multi-angle graded adjustment to meet the viewing angle needs of different scenarios such as strong light reflection avoidance and multi-person collaborative viewing.

[0017] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5The rotating rod 202 is rotatably connected to the connecting cylinder 206. A lead screw 3 is fixedly connected to the bottom of the outer wall of the support block 208. A gear 4 is sleeved on the outer wall of the lead screw 3. A worm gear 5 is meshed with the outer wall of the gear 4. A rocker arm 6 is provided at the front end of the outer wall of the worm gear 5. An installation box 7 is rotatably connected to the rear side of the outer wall of the worm gear 5. Track rods 8 are provided on the top and bottom sides of the outer wall of the installation box 7. A base 9 is fixedly connected to the bottom of the outer wall of the track rod 8. A locking block 10 is fixedly connected to the inner wall of the track rod 8. A track groove 11 is opened at the corresponding position of the locking block 10 on the outer wall of the lead screw 3. The height adjustment is achieved by using a mechanical transmission structure of rocker arm 6, worm gear 5, gear 4 and lead screw 3. Compared with the hydraulic lifting structure, oil leakage and powder are completely avoided. Dust jamming problem; compared with electric lifting structure, no additional power supply is required, reducing equipment cost and maintenance difficulty, and making it more flexible to adapt to temporary construction scenarios. The locking block 10 on the inner wall of the track rod 8 and the track groove 11 on the outer wall of the lead screw 3 form a guide and limit mechanism, which not only prevents the circumferential rotation of the lead screw 3 during the lifting process, but also guides the axial movement of the lead screw 3, effectively avoiding the shaking and tilting of the main body 1 of the device during the lifting process, and improving the stability and safety of height adjustment. In addition, the meshing structure of the worm gear 5 and the gear 4 has a self-locking characteristic, and can be automatically locked after adjustment to the target height, without the need for an additional locking mechanism, further simplifying the structural design.

[0018] Working principle: In the initial state, spring 204 is in a naturally extended state, applying an upward elastic force to mounting plate 203, causing the first limiting block 205 on the outer wall of mounting plate 203 to tightly engage with the second limiting block 207 on the inner wall of connecting cylinder 206. At this time, the angle of the main body 1 of the device is locked and cannot be rotated. When it is necessary to adjust the angle of the main body 1 of the device, the operator manually presses the connecting rod 201 towards the connecting cylinder 206. The connecting rod 201 drives the rotating rod 202 to move synchronously. The rotating rod 202 drives the mounting plate 203 to move downward inside the connecting cylinder 206, thus installing... The disc 203 applies pressure to the spring 204, causing the spring 204 to be compressed. As the mounting disc 203 moves down, the first limiting block 205 and the second limiting block 207 gradually disengage. At this time, the angle lock of the device body 1 is released. The operator rotates the device body 1 around the rotating rod 202 as the axis, adjusts it to the target angle, and then releases the connecting rod 201. Under the action of the elastic restoring force, the spring 204 pushes the mounting disc 203 upward to reset. The first limiting block 205 and the second limiting block 207 re-engage, and the angle of the device body 1 is locked again, completing the angle adjustment process. Height adjustment is achieved through the coordinated action of rocker arm 6, worm gear 5, gear 4, lead screw 3, and track rod 8. Initially, the bottom of lead screw 3 is stably embedded inside track rod 8, and the locking block 10 on the inner wall of track rod 8 is embedded in the track groove 11 on the outer wall of lead screw 3, providing circumferential limiting and preventing rotation. When it is necessary to raise the main body 1 of the device, the operator rotates rocker arm 6 clockwise. Rocker arm 6 drives worm gear 5 to rotate synchronously. Since worm gear 5 meshes with gear 4, the rotation of worm gear 5 drives gear 4 to rotate counterclockwise. The middle part of gear 4 is threadedly connected to lead screw 3, and lead screw 3 cannot rotate with gear 4 due to the limiting effect of locking block 10 and track groove 11. Therefore, the rotation of gear 4 is converted into upward movement of lead screw 3 along the axial direction of track rod 8. The top of lead screw 3 is open... The connecting cylinder 206 is connected to the rotating component and the main body 1 of the device. Therefore, the upward movement of the lead screw 3 causes the main body 1 of the device to rise synchronously. When it is necessary to lower the main body 1 of the device, the operator rotates the rocker arm 6 counterclockwise. The rocker arm 6 drives the worm gear 5 to rotate in the opposite direction, which in turn drives the gear 4 to rotate clockwise. Under the action of the threaded transmission and the limiting structure, the lead screw 3 moves downward along the track rod 8, and the main body 1 of the device lowers synchronously. After adjusting to the target height, the rocker arm 6 is stopped. Since the meshing of the worm gear 5 and the gear 4 has a self-locking property, it can prevent the gear 4 from rotating on its own, thereby keeping the main body 1 of the device stably at the target height. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
