[0031] As Figures 1 to 5 As commonly shown, this embodiment provides a fault detection device based on a rocket launcher and a howitzer. This fault detection device based on a rocket launcher and a howitzer includes a detection box 1 and a fixing member 2 installed inside the detection box 1;

[0032] The fixing member 2 includes a moving plate 21 and a fixing plate 22 installed inside the detection box 1. Both the moving plate 21 and the fixing plate 22 are V-shaped. Both ends of the moving plate 21 are fixedly connected with first baffles 211. There are three groups of first baffles 211. A first card slot 212 is formed between two groups of first baffles 211. The bottom of the first baffle 211 is fixedly connected with a slider 213. The moving plate 21 is movably connected with the detection box 1 through the slider 213. The moving plate 21 and the fixing plate 22 are symmetrical to each other. When they intersect, square pressure sensors of different specifications can be fixed.

[0033] Both ends of the fixing plate 22 are fixedly connected with second baffles 221. There are two groups of second baffles 221. Second card slots 222 are formed between two groups of second baffles 221 and on both sides. The bottom of the second baffle 221 is fixedly connected with a fixing block 223. The fixing block 223 is located inside the detection box 1 and is fixedly connected with it. The fixing plate 22 is fixedly connected with the detection box 1 through the fixing block 223.

[0034] The first baffle 211 is located inside the second card slot 222 and is movably connected with it. The second baffle 221 is located inside the first card slot 212 and is movably connected with it. In this way, the first baffle 211 and the second baffle 221 can be staggered with each other, thereby ensuring the stability of fixing the pressure sensor and fixing pressure sensors of different specifications and sizes at the same time.

[0035] A chute 24 is opened inside the detection box 1. The slider 213 is located inside the chute 24 and is movably connected with it. In this way, the stability of the moving plate 21 during movement can be ensured.

[0036] A support seat 23 is fixedly connected inside the detection box 1 and on one side of the moving plate 21. The top of the support seat 23 is fixedly connected with a collar 231. A bolt 232 is threadedly connected inside the collar 231. The bolt 232 penetrates through the collar 231, and one end of it extends into the moving plate 21 and is rotatably connected with it, so as to drive the moving plate 21 to move towards the fixing plate 22 to achieve the purpose of fixing pressure sensors of different specifications and sizes.

[0037] The other end of the bolt 232 is fixedly connected with a rotating shaft 233. A rubber ball 234 is installed on the outer surface of the rotating shaft 233. The rubber balls 234 are arranged in an annular array. Auxiliary members 25 are installed inside both the fixing plate 22 and the moving plate 21, which is convenient for the operator to rotate them.

[0038] The auxiliary member 25 includes a mounting plate 251 movably connected inside the fixing plate 22 and the moving plate 21, such as Figure 4As shown in the figure, a groove is provided inside the mounting plate 251, which facilitates the connection with the fixed plate 22 and the moving plate 21. Rubber strips 252 are arranged at equal intervals on the inner side of the mounting plate 251. One end of the mounting plate 251 and located outside the fixed plate 22 and the moving plate 21 is fixedly connected with a connecting rod 253. The arrangement of the rubber strips 252 facilitates the fixing of the circular pressure sensor, and further can achieve the purpose of fixing multiple groups of shape pressure sensors. The connecting rod 253 can facilitate the driving of the two mounting plates 251, and further can improve the work efficiency;

[0039] A guide bar 254 is fixedly connected to the outside of the mounting plate 251, and a magnet 255 is installed on the inner side of the mounting plate 251 and close to the connecting rod 253.

[0040] The auxiliary part 25 further includes a guide groove 257 opened inside the fixed plate 22 and the moving plate 21. The guide bar 254 is located inside the guide groove 257 and is movably connected to it. An iron block 256 is installed on the top of the guide groove 257 and outside the fixed plate 22 and the moving plate 21. The magnet 255 is located on one side of the iron block 256 and is magnetically connected to it, which can facilitate the positioning of the mounting plate 251 and prevent it from falling off the fixed plate 22 and the moving plate 21 due to external factors.

[0041] During use, place the pressure sensor inside the moving plate 21 and the fixed plate 22. Then rotate the rotating shaft 233 to make it rotate along the inside of the collar 231. At the same time, push the moving plate 21 to move slowly along the inside of the chute 24 through the slider 213 at its bottom towards the fixed plate 22. During this process, the first baffle 211 will be located inside the second card slot 222 as the moving plate 21 moves, and the second baffle 221 will be located inside the first card slot 212 until the fixed plate 22 and the moving plate 21 completely fix the pressure sensor. In this way, the purpose of adapting to pressure sensors of different specifications can be achieved. When it is necessary to disassemble the pressure sensor, rotate the rotating shaft in the reverse direction, which can facilitate the detection operation of the follow-up control system in the rocket launcher and the howitzer;

[0042] At the same time, when fixing the circular pressure sensor, drive the two mounting plates 251 through the connecting rod 253 to move towards the inside of the fixed plate 22 and the moving plate 21, and move along the inside of the guide groove 257 through the guide bar 254 to maintain the stability during installation until the mounting plate 251 is completely immersed in the fixed plate 22 and the moving plate 21. At this time, the magnet 255 and the iron block 256 will be magnetically connected, and at the same time, the rubber strips 252 will be located inside the fixed plate 22 and the moving plate 21 to facilitate the fixing of the circular pressure sensor, which can increase the practicability of the detection device and can also fix pressure sensors of different shapes.
