For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] Example 1

[0029] This embodiment proposes an explosion-proof touch operation terminal, such as Figure 1 and Figure 2 As shown, it includes an explosion-proof upper shell 1 and an explosion-proof lower shell 3. The explosion-proof upper shell 1 is fixedly connected to the explosion-proof lower shell 3 by screws. An explosion-proof touch screen 2 is fixedly installed at the center of the explosion-proof upper shell 1, and a terminal controller 6 is fixedly installed on the inner wall of the explosion-proof lower shell 3. The terminal controller 6 is electrically connected to the explosion-proof touch screen 2.

[0030] like Figure 2 and Figure 3As shown, an airbag 4 is provided inside the explosion-proof lower shell 3, and the airbag 4 includes a main bag body 41, sand 45 and a partition plate 46. The partition plate 46 is fixedly installed on the inner wall of the explosion-proof upper shell 1, and the main bag body 41 is installed between the explosion-proof upper shell 1 and the partition plate 46. The inside of the main bag body 41 is filled with sand 45. When the explosion-proof upper shell 1 is subjected to the impact force of the explosion, the sand 45 shares the impact force for buffering, thereby reducing the deformation of the explosion-proof upper shell 1.

[0031] There is a gap between the explosion-proof lower shell 3 and the partition plate 46, and the main bladder 41 fills the seam between the explosion-proof upper shell 1 and the explosion-proof lower shell 3. The gas in the main bladder 41 expands the main bladder 41, causing it to block the seam between the explosion-proof upper shell 1 and the explosion-proof lower shell 3, preventing external dust from entering the interior of the explosion-proof upper shell 1 and the explosion-proof lower shell 3. A buffer space is formed between the explosion-proof upper shell 1 and the partition plate 46, and the partition plate 46 separates the main bladder 41 from the terminal controller 6.

[0032] like Figure 4 As shown, an integrally formed partition layer 42 is fixedly mounted inside the main bladder 41. The partition layer 42 divides the main bladder 41 into a first sub-bladder 43 and a second sub-bladder 44. The first sub-bladder 43 is filled with air, while the second sub-bladder 44 is filled with sand 45. When an explosion generates flames, when the flames enter through the gap between the explosion-proof upper shell 1 and the explosion-proof lower shell 3, the fire burns through the main bladder 41, shattering it. The sand 45 inside the main bladder fills the partition plate 46, extinguishing the flames and blocking them inside the partition plate 46, preventing the flames from entering.

[0033] The main bladder 41 adopts a square-shaped structure. The first sub-bladder 43 faces the explosion-proof upper shell 1, and the second sub-bladder 44 faces the partition 46. The volume of the first sub-bladder 43 is smaller than that of the second sub-bladder 44, reducing the impact force generated by the first sub-bladder 43 breaking. The first sub-bladder 43 is adjacent to the joint between the explosion-proof upper shell 1 and the explosion-proof lower shell 3, while the outer wall of the second sub-bladder 44 is adjacent to the explosion-proof upper shell 1 and the explosion-proof lower shell 3.

[0034] When the flame enters from the gap, the first sub-bag 43 is burned by the flame first, and the first sub-bag 43 bursts due to the heat. The first sub-bag 43 bursts and causes the second sub-bag 44 to break. Under the action of the air inside the first sub-bag 43, the sand scatters inside the partition plate 46 and extinguishes the flame.

[0035] Sealing rubber is fixedly installed at the joint between the explosion-proof upper shell 1 and the explosion-proof lower shell 3. The flame heating softens the sealing rubber and makes it sticky. The sand 45 spreads and adheres to the sealing rubber, further improving the sealing effect.

[0036] In this embodiment, the first sub-bag 43 is attached to the joint between the explosion-proof upper shell 1 and the explosion-proof lower shell 3. When the flame generated by the explosion enters from the joint between the explosion-proof upper shell 1 and the explosion-proof lower shell 3, the first sub-bag 43 is burned and exploded by the flame. The gas inside the first sub-bag 43 causes the sand 45 inside the second sub-bag 44 to scatter, covering the flame in the gap, and the sand 45 is filled in the partition plate 46 to prevent the flame from entering.

[0037] Example 2

[0038] Based on Example 1, this embodiment proposes an explosion-proof touch operation terminal, such as Figure 2 As shown, the inner wall of the explosion-proof upper shell 1 is provided with an air supply component 5, which includes a pressure sensor 51 and a micro air pump 52. The pressure sensor 51 is electrically connected to the micro air pump 52 through a controller, and the pressure sensor 51 and the micro air pump 52 are both fixedly mounted on the inner wall of the explosion-proof lower shell 3.

[0039] like Figure 2 As shown, the end of the pressure sensor 51 contacts the first sub-bladder 43, and the micro air pump 52 is in communication with the first sub-bladder 43. The pressure sensor 51 is squeezed by the first sub-bladder 43 to determine the amount of gas inside the first sub-bladder 43. When the gas inside the first sub-bladder 43 is at a set value, the pressure sensor 51 is squeezed by the first sub-bladder 43. However, due to air leakage in the airbag, when the gas inside the first sub-bladder 43 leaks, the first sub-bladder 43 and the pressure sensor 51 are separated. At this time, the pressure sensor 51 activates the micro air pump 52 through the controller, and the micro air pump 52 fills the first sub-bladder 43 with gas.

[0040] In this embodiment, the gas inside the first sub-bag 43 leaks, and the squeezing force of the first sub-bag 43 on the pressure sensor 51 gradually decreases. When the first sub-bag 43 is separated from the pressure sensor 51, the pressure sensor 51 fills gas into the interior of the first sub-bag 43 through the micro air pump 52 to replenish the gas inside the first sub-bag 43, so as to avoid insufficient gas inside the first sub-bag 43 to spread the sand 45 to the surroundings when the first sub-bag 43 is burned and exploded by flames.

[0041] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
