The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.
[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a protective structure for a liquid crystal display screen suitable for extreme temperatures, including a wide-temperature liquid crystal screen 10 and a protective box. The protective box consists of a front box 1 and a rear box 2. The open end of the rear box 2 is inserted into the open end of the front box 1. A sealing frame 12 is installed on the end face inside the front box 1. The wide-temperature liquid crystal screen 10 is inserted into the sealing frame 12, and the outer side of the wide-temperature liquid crystal screen 10 is sealed by the sealing frame 12. An air inlet pipe 9 is installed on the rear box 2, and a fan is installed in the air inlet pipe 9. Multiple sliding grooves 5 are provided on the top surface of the rear box 2. Screw holes are provided on the top surface of the front box 1 opposite to the sliding grooves 5. Each screw hole is threaded with a hand-tightening bolt 3, and the lower end of each hand-tightening bolt 3 is inserted into the sliding groove 5.
[0022] The fan is a hot air blower, which can be adjusted to blow hot air or room temperature air. The hot air can heat the wide-temperature LCD screen to adapt to cold regions, while the room temperature air can dissipate heat from the wide-temperature LCD screen to adapt to hot regions.
[0023] In this embodiment, the top and bottom surfaces of the front housing 1 are provided with strip-shaped openings, and positioning plates 11 are inserted into the strip-shaped openings. One end of each positioning plate 11 extends to the outside and is equipped with a panel 7. The other end extends into the interior of the front housing 1 and is set to abut against the back of the outer shell of the wide-temperature LCD screen 10. Multiple locking blocks are protruding on the inner side of each panel 7. The outer side of the front housing 1 is provided with a slot opposite to the locking block. The locking blocks are inserted into the slots and are locked in place.
[0024] In this embodiment, compression springs 6 are installed in all slides 5, and the other end of each compression spring 6 is set to abut against the hand-tightening bolt 3.
[0025] In this embodiment, the front housing 1 is made of transparent plastic material, so that the content displayed on the wide-temperature LCD screen can be clearly seen through the front housing.
[0026] In this embodiment, air outlets 8 are provided on both sides of the rear housing 2, and a filter screen is installed in the opening on the outside of the air inlet pipe 9. After the fan is started, the air generated by the fan blows directly onto the wide-temperature LCD screen until it is discharged through the air outlet to complete convection and increase the heating or heat dissipation effect.
[0027] In this embodiment, multiple mounting bases 4 are installed on the back of the rear housing 2. The mounting bases 4 are provided with multiple straight slots, and screws can pass through the straight slots to fix the mounting bases in any position.
[0028] In this embodiment, a frame-shaped sealing groove is provided on the inner side of the sealing frame 12, and a frame-shaped sealing ring is installed in the sealing groove. The inner ring surface of the sealing ring abuts against the outer side of the wide-temperature LCD screen 10, and the front end face of the wide-temperature LCD screen 10 abuts against the inner wall surface of the front housing 1. The sealing ring increases the sealing between the wide-temperature LCD screen and the sealing frame, preventing external moisture from entering the interior.
[0029] During installation, first pull the panel outward to disengage the clips from the slots. The movement of the panel simultaneously moves the positioning plate. After the positioning plate moves away from the outside of the sealing frame, the wide-temperature LCD screen can be placed inside the sealing frame, with the front end of the wide-temperature LCD screen abutting against the inner wall of the front housing. After completion, reinsert the positioning plate to move it to the back of the wide-temperature LCD screen, preventing the wide-temperature LCD screen from falling out of the sealing frame.
[0030] After the above is completed, insert the rear box into the front box and rotate the hand-tightening bolt so that the lower end of the hand-tightening bolt is inserted into the slide groove. By using the hand-tightening bolt instead of the slider, the front box can only move back and forth along the slide groove. When it is impacted, the front box can move backward and the elasticity of the compression spring can play a buffering role.
[0031] Conversely, after removing the hand-tightened bolts from the slide, the front housing can be directly removed from the rear housing, and the positioning plate can be pulled out again, allowing the wide-temperature LCD screen to be directly removed, greatly facilitating installation and disassembly.
[0032] During use, the fan is activated according to the temperature of the external environment. The fan can dissipate heat or heat the wide-temperature LCD screen to adapt to different extreme environments.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
