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.

[0023] See also Figure 1-6 The utility model provides a technical solution: a protective structure for a positive pressure explosion-proof cabinet touch screen, comprising a cabinet door 1, a mounting cavity 13 is provided on the front of the cabinet door 1, a display 4 is fixedly installed in the mounting cavity 13, an anti-impact component 3 is arranged in the mounting cavity 13 and in front of the display 4, the anti-impact component 3 includes a protective net 31, and the inner walls at the upper and lower ends of the mounting cavity 13 are provided with accommodating cavities 15 matching the protective net 31, a limiting component for fixing the position of the protective net 31 is arranged between the accommodating cavity 15 and the protective net 31, and a dust blocking component 2 for covering the mounting cavity 13 is rotatably arranged on the front of the cabinet door 1.

[0024] Specifically, the cabinet door 1 is the door body of a positive pressure explosion-proof cabinet, the display 4 is the existing technology, and its surface is a touch screen. The anti-impact component 3 can protect the front of the display 4 to avoid damage to the display 4 due to inadvertent collision, thereby reducing safety hazards. The limit component fixes the position when the anti-impact component 3 protects the front of the display 4, and the dust blocking component 2 prevents dust from entering the installation cavity 13.

[0025] The end of the protective net 31 extends into the installation cavity 13 and is slidably connected thereto. The inner walls of the installation cavity 13 and the left and right ends of the accommodating cavity 15 are both provided with T-shaped grooves 14. The end of the protective net 31 is fixedly connected with a T-shaped block 32 matching the T-shaped groove 14, and the limiting component is arranged in the T-shaped block 32.

[0026] Specifically, the protective net 31 slides in the installation cavity 13, so that it can not only protect the front of the display 4, but also when the display 4 is in use, the protective net 31 can be slid and retracted into the accommodating cavity 15, so as not to interfere with the use of the display 4. The sliding of the protective net 31 is guided by the T-shaped block 32 and the T-shaped slot 14.

[0027] The limit assembly includes a block 33 whose end extends into the T-block 32 and is slidably connected thereto. The inner wall of the T-slot 14 is provided with a slot 141 matching the block 33 .

[0031] The dust blocking assembly 2 includes a transparent protective layer 21 . The front side of the cabinet door 1 and one end located in the installation cavity 13 are fixedly connected to two bosses 11 . One end of the transparent protective layer 21 is located between the two bosses 11 and is rotatably connected thereto via a rotating shaft 22 .

[0032] Specifically, the transparent protective layer 21 is provided so that when covering the installation cavity 13 , it can protect the installation cavity 13 to prevent dust from entering the installation cavity 13 , and also can not interfere with the normal observation of the display 4 .

[0033] The front side of the cabinet door 1 and the other end of the installation cavity 13 and the inner side of the transparent protective layer 21 are fixedly connected with mutually adsorbed magnetic elements 12 .

[0034] Specifically, the magnetic elements 12 are attracted to each other to fix the position of the transparent protective layer 21 , so that the transparent protective layer 21 can cover the installation cavity 13 .

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] During operation, the protective net 31 is pulled to cover the front of the display 4 until the block 33 contacts the slot 141 . At this time, the spring 34 drives the block 33 to fit into the slot 141 to fix the position of the protective net 31 . Then, the transparent protective layer 21 is rotated to cover the installation cavity 13 .
