Description

Technical Field

[0001] This utility model relates to the field of fireproof glass door technology, and in particular to an alarm fireproof glass door with an LCD display. Background Technology

[0002] Fire-resistant glass doors are made of cesium potassium fire-resistant glass, composite fire-resistant glass, or high-stress monolayer fire-resistant glass through a multi-layer composite process. When heated, the glass expands to form a heat insulation layer, which slows down heat conduction. The doors are made of steel or aluminum alloy and filled with fire-resistant and heat-insulating materials such as rock wool to ensure structural stability at high temperatures. The door seams are equipped with expansion sealing strips, which expand when heated to seal the gaps and block more than 80% of toxic fumes.

[0003] A patent for a glass door with an automatic opening and closing liquid crystal display (publication number CN110630145A) was found, which includes a door frame, a first glass door, a second glass door, a first liquid crystal display, a second liquid crystal display, three temperature sensors, and a kinetic energy conversion device. The door frame has an entrance space 1 and an entrance space 2 symmetrically arranged on both sides along its length. The first glass door is slidably connected to one side of the inner surface of the door frame, and the second glass door is slidably connected to the other side of the inner surface of the door frame. The second glass door is located on the outward side of the first glass door. One side of the second glass door is located near the entrance space 2 of the door frame. The other side of the second glass door is embedded with three temperature sensors. The kinetic energy conversion device is provided on the inner surface of the bottom end of the door frame.

[0004] Existing technology describes a glass door integrating a temperature sensor, an LCD screen (embedded in the door body), and an automatic opening and closing system. However, it still has shortcomings in use. The display screen cannot be height adjusted, making it impossible to adjust for different usage environments and differences in user height, resulting in poor flexibility of use. Therefore, we propose an alarm fireproof glass door with an LCD display to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an alarm fireproof glass door with an LCD display.

[0016] like Figures 1-5 As shown, the present invention proposes an alarm fireproof glass door with liquid crystal display, comprising a door frame 1, a display screen housing 4, a base 5, a shield 9, and a guide rail 14. The inner wall of the door frame 1 is provided with glass 2. The display screen housing 4 is provided inside the front end of the door frame 1. The shield 9 is sleeved on the outer side of the display screen housing 4. An alarm 7 is provided on the upper end of the shield 9. The front end of the display screen housing 4 is provided with a liquid crystal display screen 6. The lower end of the display screen housing 4 is provided with a base 5. The two ends of the base 5 are provided with sliders 13. The inner walls on both sides of the door frame 1 are provided with guide rails 14 that are slidably installed with the sliders 13. The upper end of the base 5 is provided with a side plate 16. The inner walls of both sides of the display screen housing 4 are provided with guide rails 12, and the inner wall of the shield 9 is provided with symmetrically distributed sliders 11. The sliders 11 are slidably installed on the outer wall of the guide rails 12. The upper side of the shield 9 is provided with a wiring hole 8, and the front end of the shield 9 is provided with a viewing panel 10. The shield 9 is provided with a support base 26 at one end, and an installation shaft 27 is rotatably mounted at one end of the support base 26. A handle 29 is provided at one end of the installation shaft 27, and an installation groove 3 is provided inside the door frame 1. The mounting shaft 27 is sleeved with a torsion spring 28 whose two ends are respectively connected to the handle 29 and the support 26. One end of the shield 9 is provided with a limiting block 25 located on the rotation path of the handle 29. The outer wall of the guide rail 14 is provided with side holes 17 for lamp distribution. The lower end of the base 5 is provided with a guide plate 23. A rod 18 is slidably inserted into the guide plate 23. A support ring 21 is sleeved on the outer wall of the rod 18. A spring 22 is provided between the support ring 21 and the guide plate 23 and sleeved on the outside of the rod 18. A handle 24 is provided at one end of the rod 18. A spring 15 is provided at one end of the side plate 16, a side ring 20 is provided at one end of the spring 15, a positioning rod 30 passes through the inside of the side ring 20, a handle 31 is provided at the upper end of the side ring 20, a positioning hole 32 and a positioning hole 33 are provided on the outer wall of the shield 9, and a positioning cylinder 19 located inside the spring 15 and connected to the support at one end is sleeved on the outside of the positioning rod 30. Based on the implementation steps of Embodiment 1: During operation, the user can grasp the handle 29 on one side of the shield 9 and press it down to overcome the elastic force of the torsion spring 28 and make the handle 29 rotate around the mounting shaft 27. After disengaging from the contact with the limiting block 25, the user can push and pull the shield 9 longitudinally, so that it slides along the guide rails 12 on both sides of the display screen housing 4 through the inner wall slider 11. Simultaneously, the sliders 13 at both ends of the base 5 move longitudinally on the guide rails 14 on the inner wall of the door frame 1, thereby realizing the adjustment of the overall height of the display screen. After adjusting to the appropriate position, release handle 29. Torsion spring 28 resets and drives handle 29 to automatically fit against the outer wall of shield 9, completing the initial positioning. At the same time, pull handle 24 at the lower end of base 5, so that the insertion rod 18 overcomes the elastic force of spring 22 and disengages from the side hole 17 of guide rail 24. After adjusting base 5 to the target height, release handle 24. Spring 22 drives insertion rod 18 to re-insert into the corresponding side hole 17, completing the secondary positioning. At this time, LCD screen 6 clearly displays information through the visual panel 10 at the front of shield 9. Temperature sensor monitors ambient temperature in real time. When abnormal, alarm 7 is triggered to sound an alarm. Traditional fireproof glass doors with LCD screens cannot accommodate users of different heights due to their fixed installation. This device, however, constructs a dual-degree-of-freedom adjustment system through the sliding connection between the shield 9 and the display housing 4, and the sliding connection between the base 5 and the door frame 1, allowing users to flexibly adjust the height of the display screen. The handle 29 driven by the torsion spring 28 cooperates with the limit block 25 to provide initial limit to prevent the shield 9 from sliding at will. The mechanical positioning structure formed by the plug rod 18, the spring 22 and the guide rail side hole 17 achieves precise height locking to avoid displacement caused by vibration or external force. In addition, the shield 9 provides physical protection for the LCD screen to reduce external interference such as collisions and dust. The wiring hole 8 design ensures that the wiring of the alarm 7 and the display screen is concealed and safe. The problem of poor adaptability caused by the fixed height of the LCD screen in traditional technology is solved by the dual sliding adjustment and elastic positioning of this device. Users can quickly adjust the height of the display screen according to actual needs such as children, adults or special scenarios, to improve the interactive experience. The protective design of the shield 9 extends the service life of the LCD screen and reduces maintenance costs. At the same time, the integrated temperature detection and alarm function makes the fireproof glass door not only have basic fire protection performance such as heat insulation and smoke blocking, but also adds real-time early warning capability, which meets the comprehensive safety requirements of modern buildings. Through structural innovation and functional integration, this device solves the problems of traditional equipment such as non-adjustable display screen height and weak protection while ensuring fire resistance. It features easy operation, strong adaptability, and safety and reliability, and is suitable for scenarios with high requirements for personnel evacuation guidance and fire early warning, such as shopping malls, hospitals, and office buildings.
