[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1, an embodiment of the utility model: a liquid crystal display screen with a cold-resistant structure, including a support column 1, a mounting frame 2 is fixedly connected to the top of the support column 1, support rails 5 are fixedly connected to both sides of the interior of the mounting frame 2, a temperature detector 14 is fixedly connected to the middle of the top of the support rail 5, a fixed frame 3 is slidably connected to the interior of the mounting frame 2, a handle bar 4 is fixedly connected to the middle of the front end of the fixed frame 3, a main display screen 13 is fixedly connected to the interior of the fixed frame 3, a transparent heating frame 7 is fixedly connected to the top of the interior of the mounting frame 2, a transmission heating groove 21 is opened in the transparent heating frame 7, and a plurality of outer discharge holes 6 are evenly opened at the front end of the transparent heating frame 7 A heating protection component is installed inside the support column 1, and a quick-release fixing component is installed at the rear end of the mounting frame 2. The heating protection component includes an annular heating groove 20 located on the inner wall of the mounting frame 2, and heating air outlets 15 are opened on both sides of the annular heating groove 20. A heating traction pipe 18 is fixedly connected to the middle side of the inner part of the support column 1, and a traction fan 17 is fixedly connected to the upper side of the inner part of the support column 1. The outside of the heating traction pipe 18 is fixedly connected to the electric valve seat 19, and the temperature detector 14 is electrically connected to the traction fan 17 and the electric valve seat 19 respectively. The outside of the support rail 5 is correspondingly slidably connected to the two sides of the fixed frame 3, and the inner side of the heating air outlet 15 passes through the transmission heating groove 21 respectively;

[0027] The device is mostly used in cold areas, and it is mostly heated by gas. The image displayed on the main display screen 13 is displayed through the transparent heating frame 7. The temperature detector 14 detects the temperature inside the installation frame 2. When the internal temperature of the installation frame 2 is too low, the temperature detector 14 starts the traction fan 17 and the electric valve seat 19, and the heat generated by the gas inside the heating traction pipe 18 is drawn into the top of the support column 1 through the heating traction pipe 18. The traction fan 17 accelerates the warm air into the inside of the annular heating groove 20. The warm air flows inside the annular heating groove 20, flows to the inside of the transmission heating groove 21 through the heating air outlet 15, and then is discharged to the outside through the outer exhaust hole 6. At this time, the internal temperature of the installation frame 2 rises, thereby ensuring the normal operation of the main display screen 13, further ensuring the use of the display screen in a cold environment, and improving the stability of the device.

[0028] Example 2, the quick-release fixing assembly includes mounting fixing columns 8 located on both sides of the rear end of the fixing frame 3, the inner sides of the mounting fixing columns 8 are slidably connected with buckle blocks 9, the outer sides of the buckle blocks 9 are respectively connected to the inner sides of the mounting fixing columns 8 through thrust springs 16, a main slider 10 is slidably connected to the middle of the rear end of the mounting frame 2, both sides of the bottom end of the main slider 10 are rotatably connected with push rods 11, both sides of the rear end of the mounting frame 2 are slidably connected with the sliders 12, the outer lower sides of the push rods 11 are respectively rotatably connected to the inner sides of the sliders 12, and the outer sides of the mounting fixing columns 8 respectively penetrate the two sides of the rear end of the mounting frame 2;

[0029] When the display screen needs to be disassembled, the main slider 10 is pressed downward, thereby changing the angle of the push link 11 to be vertical, thereby generating an outward thrust on the slider 12, retracting the buckle block 9 into the interior of the mounting fixing column 8. At this time, the display screen is pulled outward by the handle rod 4 for disassembly, further improving the efficiency of disassembly of the device, thereby facilitating the inspection and maintenance of the display screen.

[0030] Working principle: The device is mostly used in cold areas, and it is mostly heated by gas. The picture displayed on the main display screen 13 is displayed through the transparent heating frame 7. The temperature detector 14 detects the temperature inside the installation frame 2. When the internal temperature of the installation frame 2 is too low, the temperature detector 14 starts the traction fan 17 and the electric valve seat 19, and the heat generated by the gas inside the heating traction pipe 18 is pulled into the top of the support column 1 through the heating traction pipe 18, and the heating is accelerated into the inside of the annular heating groove 20 by the traction fan 17. The heating is heated in the annular heating groove 20. The internal flow of the heat groove 20 flows to the inner side of the transmission heating groove 21 through the heating air outlet 15, and then is discharged to the outside through the outer exhaust hole 6. At this time, the internal temperature of the installation frame 2 increases, thereby ensuring the normal operation of the main display screen 13. When the display screen needs to be disassembled, the main slider 10 is pressed downward, thereby changing the angle of the push connecting rod 11 to be vertical, thereby generating an outward thrust on the slider 12, and retracting the buckle block 9 into the interior of the installation fixing column 8. At this time, the display screen is pulled outward by the handle rod 4 for disassembly.
