Technical Field

[0001] The utility model relates to the technical field of display boards, in particular to display equipment for construction engineering services. Background Art

[0002] Construction engineering refers to the planning, investigation, design, construction, completion and other technical work and completed engineering entities for the construction, reconstruction or expansion of buildings and ancillary structures and facilities, as well as the installation of supporting lines, pipelines and equipment. It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be started and materials moved, and can only be realized through construction activities. The display equipment for construction engineering services mainly includes information service display stands, building model display stands, electronic display screens and virtual reality (VR) equipment, among which information service display stands are used to publish and display construction engineering service information.

A reinforcing plate 18 is fixedly connected to the rear side of the shielding shell 7. There are several reinforcing plates 18 and they are distributed at equal distances. The top of the reinforcing plate 18 fits with the bottom of the back plate 82.

[0035] As a technical optimization solution of the utility model, by setting a mounting seat 16, a push handle 17 and a reinforcement plate 18, the mounting seat 16 can limit the push handle 17, the push handle 17 is convenient for the user to move the position of the display board 4, and the reinforcement plate 18 can improve the stability of the connection between the back plate 82 and the shielding shell 7.

[0036] The working principle and use process of the utility model are as follows: when in use, the protective shell 13 is first pulled to make the protective shell 13 away from the display board 4, and then the construction engineering service information to be displayed is posted on the front of the display board 4, and then the plug 14 is re-inserted into the inside of the slot 15 so that the protective shell 13 can protect the display board 4 again, and then the display board 4 is moved to a specified position by the push handle 17. When the height of the display board 4 needs to be adjusted, the output end of the electric push rod 6 can push the shielding shell 7 to move upward by starting the electric push rod 6, and the upward movement of the shielding shell 7 can drive the limit plate 81 to move upward, and the upward movement of the limit plate 81 can drive the display board 4 to move upward. The display board 4 is moved to the left and right sides of the support frame 3, thereby completing the adjustment of the height of the display board 4. At the same time, when the limit plate 81 moves upward, it can drive the back plate 82 and the latch tooth 91 to move upward. Since the latch tooth 91 is meshed with the gear 92, when the back plate 82 drives the latch tooth 91 to move upward, it can drive the gear 92 to rotate. The gear 92 can limit the latch tooth 91, the back plate 82, the limit plate 81 and the display board 4, thereby improving the stability of the movement of the back plate 82. The protective shell 13 can protect the display board 4. When the display board 4 needs to be disassembled, first pull the protective shell 13 to disengage the plug post 14 from the inside of the slot 15, and then pull the display board 4 out of the inner side of the support frame 3.

[0037] To sum up: this kind of display equipment for construction engineering services, by setting a fixed plate 5, an electric push rod 6 and a shielding shell 7, the fixed plate 5 can fix and limit the electric push rod 6, and by starting the electric push rod 6, the output end of the push rod can drive the shielding shell 7 to move upward, and the upward movement of the shielding shell 7 can drive the display board 4 to move upward, which solves the problem that since the device does not have a height adjustment structure, the device can only be displayed in a place without any obstructions around it, otherwise it will be blocked and it will be difficult to fully display the construction engineering technical service information. However, in order to popularize the construction engineering technical service information more quickly, each display device needs to be moved to a different place, and each place will inevitably have obstructions. Therefore, the device does not have a height adjustment structure and has certain limitations when used.
