Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a construction progress display device. Background Art

[0002] Building engineering refers to the process of transforming a building from a concept into a physical entity through a series of professional activities such as design, construction, and management. This includes work in aspects such as building structure, material selection, construction technology, and project management. Building engineering not only involves the physical construction of a building but also includes considerations in multiple aspects such as design, planning, safety, and environmental protection. During building construction, it is necessary to display the construction progress to facilitate communication between construction workers and management personnel and improve the overall construction efficiency at the construction site.

[0003] However, the existing construction progress display devices have fixed structures and can only display content within a fixed range. They cannot be flexibly adjusted and customized according to actual needs, and cannot adapt to the special requirements and changes of different projects. Moreover, the existing construction progress display devices occupy a large amount of space, resulting in inconvenience during transportation and storage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a construction progress display device that can flexibly adjust the display range and is convenient for transportation and storage.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A construction progress display device includes a main display board. A secondary display board is inserted into the interior of the main display board, and an extension mechanism capable of driving the secondary display board to move horizontally is arranged inside the main display board. Lifting plates are installed on the opposite sides of the main display board and the secondary display board. A support plate is inserted into the interior of the lifting plate, and a lifting mechanism capable of driving the lifting plate to vertically lift is arranged inside the support plate. Bottom plates are installed at the bottoms of the lifting plates, and universal wheels are installed on both sides of the bottom of the bottom plate in its length direction.

[0007] It can be seen that through the setting of the extension mechanism, the secondary display board can be driven to expand and contract inside the main display board, and thus, according to the special requirements and changes of different projects, the display range can be flexibly adjusted, with strong applicability. When the secondary display board is completely retracted into the main display board, the overall occupied space of the device can be reduced. Through the setting of the lifting mechanism, the display height can be adjusted. When the heights of the main display board and the secondary display board are lowered, it is convenient for management personnel to stand on the ground to update the display content daily, improving the usage experience. When the support plate is completely retracted into the lifting plate, the overall occupied space of the device can be further reduced, thereby achieving the purpose of being convenient for transportation and storage.

[0008] Further, the extension mechanism includes a first threaded rod rotatably installed inside the main display board. A threaded groove is provided inside the secondary display board, and the end of the first threaded rod is arranged in the threaded groove. A first bevel gear is sleeved on the outer surface of the first threaded rod. The surface of the main display board penetrates and rotatably installs a first knob, and a second bevel gear is installed at the end of the first knob. The second bevel gear is meshed and connected with the first bevel gear.

[0009] When the first knob is rotated, it can drive the second bevel gear to rotate. Since the second bevel gear is meshed with the first bevel gear, it can drive the first threaded rod to rotate. Since the inner wall of the main display board limits the secondary display board, when the first threaded rod rotates, it can drive the secondary display board to move horizontally, achieving the purpose of adjusting the display range.

[0010] Further, the lifting mechanism includes a second threaded rod rotatably installed inside the support board. A nut seat is installed on the outer surface of the second threaded rod, a connecting block is installed on the outer surface of the nut seat, and the end of the connecting block is connected to the inner wall of the lifting board. A worm gear is sleeved on the outer surface of the second threaded rod near its bottom. A worm is rotatably installed inside the support board, and the worm is meshed and connected with the worm gear.

[0011] When the worm is rotated, it can drive the worm gear to rotate and drive the second threaded rod to rotate. Since the inner wall of the support board limits the nut seat, it can drive the nut seat to move along the surface of the second threaded rod, thus achieving the purpose of driving the lifting board to lift.

[0012] Further, a telescopic rod is rotatably installed between the two support boards, and both ends of the telescopic rod are respectively connected to the two worms. A second knob is rotatably installed on the outer surface of one of the support boards, and the end of the second knob is connected to the worm.

[0013] When the second knob is rotated, through the connection of the telescopic rod, it can drive the two worms to rotate simultaneously, and then drive the two lifting boards to lift simultaneously. This not only improves the efficiency of height adjustment, but also the heights of the two lifting boards can always be kept consistent, and the use effect is good.

[0014] Further, limiting sliding grooves are provided on both the upper and lower sides of the secondary display board, limiting sliders are arranged inside the limiting sliding grooves, and the ends of the limiting sliders are connected to the inner wall of the main display board.

[0015] Through the arrangement of the limiting sliding grooves and the limiting sliders, not only can the stability of the horizontal movement of the secondary display board be improved, but also the movement range of the secondary display board can be restricted, avoiding the situation that the secondary display board detaches from the inside of the main display board.

[0016] Further, third threaded rods vertically penetrate and are threadedly connected to both ends in the length direction of the bottom plate. A bottom pad is installed at the bottom of the third threaded rod, and a torsion rod is installed at the top of the third threaded rod.

[0017] After the device is moved to the display position through the casters, the torsion bar can be turned to drive the rotation of the third threaded rod, so that the bottom pad descends and supports the ground, thereby improving the stability of the device. Description of the Drawings

Detailed Embodiment

[0025] The present utility model will be described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-6 shown, a construction progress display device includes a main display board 100. A sub-display board 101 is inserted into the interior of the main display board 100, and an extension mechanism 200 capable of driving the horizontal movement of the sub-display board 101 is provided inside the main display board 100. Lifting boards 102 are installed on the opposite sides of the main display board 100 and the sub-display board 101. A support board 103 is inserted into the interior of the lifting board 102, and a lifting mechanism 300 capable of driving the vertical lifting of the lifting board 102 is provided inside the support board 103. A bottom board 104 is installed at the bottom of the lifting board 102, and casters 105 are installed on both sides of the bottom board 104 in the length direction at the bottom.

[0027] When in use, the device can be pushed to the display position by the universal wheels 105. Then, the secondary display board 101 is driven to move horizontally by the extension mechanism 200 to adjust the display range. Next, the display content is posted on the surfaces of the main display board 100 and the secondary display board 101 for display. When the management personnel need to update the project progress daily, the main display board 100 and the secondary display board 101 can be driven to descend by the lifting mechanism 300, so that the management personnel can stand on the ground to update and modify the project progress. When the device needs to be transported and stored, the secondary display board 101 can be completely stored inside the main display board 100 through the extension mechanism 200. The lifting plate 102 is driven to descend by the lifting mechanism 300, and the support plate 103 is completely stored inside the lifting plate 102, thereby reducing the occupied space of the device and improving the portability of transportation and storage.

[0028] Specifically, the extension mechanism 200 includes a first threaded rod 201 rotatably installed inside the main display board 100. A threaded groove 202 is formed inside the secondary display board 101, and the end of the first threaded rod 201 is arranged in the threaded groove 202. A first bevel gear 203 is sleeved on the outer surface of the first threaded rod 201. A first knob 204 penetrates and is rotatably installed on the surface of the main display board 100. A second bevel gear 205 is installed at the end of the first knob 204. The second bevel gear 205 is meshed with the first bevel gear 203. When the first knob 204 is rotated, the second bevel gear 205 can be driven to rotate. Since the second bevel gear 205 is meshed with the first bevel gear 203, the first threaded rod 201 can be driven to rotate. Since the inner wall of the main display board 100 limits the secondary display board 101, the secondary display board 101 can be driven to move horizontally when the first threaded rod 201 rotates, achieving the purpose of adjusting the display range.

[0029] Specifically, the lifting mechanism 300 includes a second threaded rod 301 rotatably installed inside the support plate 103. A nut seat 302 is installed on the outer surface of the second threaded rod 301. A connecting block is installed on the outer surface of the nut seat 302, and the end of the connecting block is connected to the inner wall of the lifting plate 102. A worm gear 303 is sleeved on the outer surface of the second threaded rod 301 near its bottom. A worm 304 is rotatably installed inside the support plate 103. The worm 304 is meshed with the worm gear 303. When the worm 304 is rotated, the worm gear 303 can be driven to rotate, and the second threaded rod 301 can be driven to rotate. Since the inner wall of the support plate 103 limits the nut seat 302, the nut seat 302 can be driven to move along the surface of the second threaded rod 301, thus achieving the purpose of driving the lifting plate 102 to lift and lower.

[0030] Specifically, a telescopic rod 400 is rotatably installed between two support plates 103, and both ends of the telescopic rod 400 are respectively connected to two worm gears 304. A second knob 401 is rotatably installed on the outer surface of one of the support plates 103, and the end of the second knob 401 is connected to the worm gear 304. When the second knob 401 is rotated, due to the connection of the telescopic rod 400, the two worm gears 304 can be driven to rotate simultaneously, and then the two lifting plates 102 can be driven to lift simultaneously, which not only improves the efficiency of height adjustment, but also enables the heights of the two lifting plates 102 to always remain the same, with good use effects.

[0031] Specifically, limiting sliding grooves 500 are formed on both the upper and lower sides of the secondary display board 101, and limiting sliding blocks 501 are arranged inside the limiting sliding grooves 500. The ends of the limiting sliding blocks 501 are connected to the inner wall of the main display board 100. Through the arrangement of the limiting sliding grooves 500 and the limiting sliding blocks 501, not only can the stability of the secondary display board 101 during horizontal movement be improved, but also the movement range of the secondary display board 101 can be restricted, avoiding the situation where the secondary display board 101 detaches from the inside of the main display board 100.

[0032] Specifically, third threaded rods 600 vertically penetrate and are threadedly connected to both ends of the bottom plate 104 in the length direction. A bottom pad 601 is installed at the bottom of the third threaded rod 600, and a torsion rod 602 is installed at the top of the third threaded rod 600. After the device is moved to the display position through the universal wheels 105, the torsion rod 602 can be rotated to drive the third threaded rod 600 to rotate, causing the bottom pad 601 to descend and support the ground, thereby improving the stability of the device.

[0033] The above is a detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several equivalent substitutions or obvious modifications are made, and if the performance or use is the same, they should all be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
