Description

Technical Field

[0001] The utility model relates to the technical field of display devices, in particular to a novel display device. Background Art

[0002] Information presentation refers to conveying specific information or content to the audience through various forms and media. Information presentation can be in a variety of ways, including text, pictures, charts, videos, animations, etc., aiming to effectively present information and attract the audience's attention.

[0003] For example, a Chinese utility model patent (CN 215764370 U) discloses a construction safety information display device for construction engineering supervision, which records: "Through the coordinated use of a base, rollers, connecting rods, round rods, rectangular plates and springs, the impact force is greatly reduced, forming a buffering effect for the information display device, avoiding damage to the information display device due to rough roads during the movement of the device, thereby improving the safety of the device." It also records: "In the prior art, most construction safety information display devices used for construction engineering supervision generally have too single functions and can only display safety information. They do not have a lifting and adjustment function. The fixed height cannot adapt to complex construction sites, which is not conducive to workers' observation of safety information. In addition, most construction safety information display devices used for construction engineering supervision do not have a shock-absorbing function and cannot adapt to the complex road conditions at the construction site, which is easy to cause damage to the information display device." Technical problems.

[0004] To sum up the above, it can be seen that the prior art uses an upright information display screen to display safety information for construction supervision. However, this method has the following technical problems: the traditional construction site environment is relatively complex, and there will be harsh environments such as a lot of dust, strong winds, and rain, and the display screen is relatively fragile. If the display screen is not protected, the display screen is easily damaged when the construction site environment is bad, which in turn causes damage to the display screen. For this reason, the present application proposes a new display device to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

[0005] Based on this, it is necessary to provide a new type of display device to address the above technical problems. By starting the first motor, the protective shell and the lifting block can be driven to rise along the direction of the threaded rod under the restriction of the first limiting rod and the second limiting rod. Then the display screen in the protective frame changes from lying flat to tilted, and finally to a state perpendicular to the device shell, and then the display screen can be started to display relevant building supervision safety information. During the display process, the protective shell is located on the top of the display screen to prevent objects from hitting the display screen from the top, thereby improving the safety of the display screen. When the environment at the construction site becomes more severe, the first motor is started to control the protective shell to descend, and at the same time drive the display screen to lie flat. Finally, the protective shell is close to the device shell, and the display screen is located inside the protective shell, which reduces the damage to the display screen caused by bad weather, thereby extending the service life of the display screen.

[0029] As described in the background art, the traditional construction site environment is relatively complex, and there may be harsh environments such as high dust content, strong winds, and rain. The display screen is relatively fragile, and if the display screen is not protected, the display screen is easily damaged when the construction site environment is bad, thereby causing damage to the display screen.

[0030] In order to solve this technical problem, the utility model provides a new display device, which is applied to provide protection for a screen for displaying safety information for construction supervision.

[0031] Specifically, please refer to Figure 1-Figure 3 , the new display device specifically includes:

[0032] The device comprises a housing 1, a brake wheel 2 is fixedly connected to the bottom of the housing 1, a heat dissipation mechanism 3 is arranged inside the housing 1, and a storage protection mechanism 4 is arranged on the top of the housing 1;

[0033] The storage protection mechanism 4 includes a first motor 5 fixedly connected to the inside of the device housing 1 , a threaded rod 6 is fixedly connected to the output end of the first motor 5 , and a protective shell 7 is threadedly connected to the outside of the threaded rod 6 .

[0034] The new display device provided by the utility model can drive the protective shell 7 and the lifting block 10 to rise along the direction of the threaded rod 6 under the restriction of the first limiting rod 8 and the second limiting rod 9 by starting the first motor 5, and then the display screen 13 in the protection frame 12 changes from lying flat to tilted, and finally becomes perpendicular to the device housing 1, and then the display screen 13 can be started to display relevant building supervision safety information. During the display process, the protective shell 7 is located on the top of the display screen 13 to prevent objects from hitting the display screen 13 from the top, thereby improving the safety of the display screen 13. When the environment on the construction site becomes worse, the first motor 5 is started to control the protective shell 7 to descend, and at the same time drive the display screen 13 to lie flat, and finally the protective shell 7 is tightly attached to the device housing 1, and the display screen 13 is located inside the protective shell 7, thereby reducing the damage to the display screen 13 due to bad weather, thereby extending the service life of the display screen 13.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] Please refer to Figure 2-Figure 5 , a new type of display device, comprising:

[0038] A first limiting rod 8 is fixedly connected to the top of the device housing 1, and the protective shell 7 is slidably connected to the outside of the first limiting rod 8. A second limiting rod 9 is fixedly connected to the top of the device housing 1, and the protective shell 7 is slidably connected to the outside of the second limiting rod 9. The first limiting rod 8 and the second limiting rod 9 limit the rotation of the protective shell 7, and the second limiting rod 9 limits the rotation of the lifting block 10, so that the protective shell 7 and the lifting block 10 can be stably lifted and lowered, thereby improving the stability of the device.

[0039] A lifting block 10 is threadedly connected to the outside of the threaded rod 6 and located at the bottom of the protective shell 7. The lifting block 10 is slidably connected to the outside of the second limiting rod 9. A protective rod 11 is fixedly connected to the top of the lifting block 10. The protective rod 11 prevents the threads between the protective shell 7 and the threaded rod 6 from sliding down and hitting the lifting block 10, the protective frame 12, and the display screen 13 due to severe wear, thereby improving the stability of the device and the safety of the display screen 13.

[0040] The outside of the lifting block 10 is rotatably connected to a protection frame 12, and the inside of the protection frame 12 is fixedly connected to a display screen 13, which can play some information related to construction engineering supervision safety for display.

[0041] A side of the protection frame 12 away from the lifting block 10 is rotatably connected to a sliding seat 14 , and both ends of the sliding seat 14 are fixedly connected to sliding blocks 15 .

[0042] A sliding groove 16 is formed on the outside of the device housing 1 , and the sliding block 15 is slidably connected in the sliding groove 16 .

[0043] Through the above structural design, when information display is required, after the device is transported to the designated position, the first motor 5 is started to drive the threaded rod 6 to rotate. The protective shell 7 rises along the direction of the threaded rod 6 under the rotation of the threaded rod 6 and with the assistance of the first limiting rod 8 and the second limiting rod 9. At the same time, the lifting block 10 rises along the rotation of the threaded rod 6 with the assistance of the second limiting rod 9. The upper body of the lifting block 10 drives the protective frame 12 and the display screen 13 from lying flat to tilting, and at the same time, the protective frame 12 and the lifting block 10, and the protective frame 12 and the sliding seat 14 rotate, and The sliding block 15 slides along the sliding groove 16 to the position of the threaded rod 6, and finally the protection frame 12 and the display screen 13 can be changed to a state perpendicular to the device housing 1, and then the display screen 13 can be started to display the relevant construction supervision safety information. At this time, the protective shell 7 is located on the top of the display screen 13. When the environment at the construction site becomes worse, the first motor 5 is started to control the protective shell 7 to descend, and at the same time drive the lifting block 10 to descend, so that the protection frame 12 and the display screen 13 gradually become a lying state, and finally the protective shell 7 is tightly attached to the device housing 1, and the display screen 13 is located inside the protective shell 7.

[0044] Embodiment 2:

[0045] The novel display device provided in Example 1 is further optimized, specifically, as follows: Figure 4-Figure 5As shown, the heat dissipation mechanism 3 includes a dustproof net 17 fixedly connected to the inside of the device housing 1. The dustproof net 17 prevents dust from the construction site from entering the inside of the device housing 1 with the flow of air, and then blowing toward the protection frame 12 and the display screen 13, thereby improving the protection of the display screen 13 and the second motor 18. The inside of the device housing 1 is fixedly connected to the second motor 18, and the output end of the second motor 18 is fixedly connected to the fan blade 19. A plurality of ventilation holes 20 are opened on the top of the device housing 1.

[0046] Through the above-mentioned structural design, when the outdoor temperature is high, the second motor 18 can be started to drive the fan blades 19 to rotate, thereby driving the air flow, so that the air passes through the dustproof net 17 and enters the interior of the device housing 1, and then blows toward the protective frame 12 and the display screen 13 through the vent 20, thereby dissipating the heat of the display screen 13.
