Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1, by Figure 1-5 The utility model relates to an impact-resistant combined pressure distribution measuring device, comprising a base 1, side plates 2 are symmetrically installed at both ends of the base 1, two guide rods 3 are symmetrically installed between the two side plates 2, and a plurality of pressure detection devices 4 are arranged on the base 1;

[0025] The pressure detection device 4 includes a bottom platform 401 arranged above the base 1, a top platform 402 is arranged above the bottom platform 401, support columns 403 are installed at the four corners between the bottom platform 401 and the top platform 402, a fixed cylinder 404 is installed between the bottom platform 401 and the top platform 402, a movable plate 405 is movably installed inside the fixed cylinder 404, a pressure sensor 406 is installed on the inner bottom wall of the fixed cylinder 404, an induction spring 407 is installed between the bottom end of the movable plate 405 and the pressure sensor 406, a pressure rod 408 is installed at the top of the movable plate 405, and the top of the pressure rod 408 penetrates The top of the bottom platform 401 is symmetrically provided with two matching grooves 409, and the two matching grooves 409 correspond to the two guide rods 3 respectively. An auxiliary fixing component 5 is installed between the bottom platform 401 and the base 1. The two matching grooves 409 are provided with side grooves 410 on the sides away from each other. A limit block 411 is slidably installed inside the side groove 410. When the limit block 411 enters the matching groove 409 from the side groove 410, the inner top wall of the matching groove 409 and the top wall of the limit block 411 contact the upper and lower sides of the guide rod 3 respectively. The two limit blocks 411 are both provided on the sides away from each other. A first screw rod 412 is installed, and the first screw rod 412 is threadedly installed inside the first screw barrel 413. The two first screw barrels 413 are symmetrically installed on both sides of the bottom platform 401, and the two first screw barrels 413 are respectively connected with the two matching grooves 409. A limit rotation block 415 is installed at one end of the first screw rod 412 close to the limit block 411. The limit rotation block 415 is rotatably installed inside the limit rotation groove 414. The limit rotation groove 414 is opened inside the limit block 411. During work, the two matching grooves 409 on the bottom platform 401 of the pressure detection device 4 are respectively engaged with the two guide rods 3. It is convenient to install each pressure detection device 4 to the position where pressure distribution detection is required, to adjust the pressure distribution detection position, and to increase or decrease the pressure distribution detection position, so that it is convenient to use in combination. The first screw barrel 413 on both sides of the bottom platform 401 is turned to make the limit block 411 in the side groove 410 enter the matching groove 409, so that the upper and lower sides of the guide rod 3 are respectively tightly attached to the inner top wall of the matching groove 409 and the top wall of the limit block 411, thereby limiting the pressure detection device 4 to avoid displacement due to impact, thereby improving the impact resistance of the pressure detection device 4.

[0026] The auxiliary fixing component 5 includes a fixed friction plate 501 installed on the front side of the base 1, and two horizontal plates 502 are symmetrically installed on the front side of the bottom platform 401, and the horizontal plate 502 is located above the fixed friction plate 501. A second screw barrel 503 is installed on the horizontal plate 502, and a second screw rod 504 is installed on the internal thread of the second screw barrel 503, and a bottom friction plate 505 is installed on the bottom end of the second screw rod 504. The second screw rod 504 on the horizontal plate 502 is screwed. Since the second screw rod 504 is threadedly connected to the second screw barrel 503, the second screw rod 504 moves downward, so that the bottom wall of the bottom friction plate 505 is tightly attached to the fixed friction plate 501, so that under the action of friction, the pressure detection device 4 can remain fixed to the base 1, further improving the impact resistance of the pressure detection device 4.

[0027] Working principle: When working, first fix the base 1 below the impact pressure test position, install the pressure detection device 4 at the position where the pressure detection is required, first engage the two matching grooves 409 on the bottom platform 401 of the pressure detection device 4 with the two guide rods 3 respectively, and screw the first screw barrels 413 on both sides of the bottom platform 401 to make the limit blocks 411 in the side grooves 410 enter the matching grooves 409, so that the upper and lower sides of the guide rods 3 are respectively in close contact with the inner top wall of the matching groove 409 and the top wall of the limit blocks 411, thereby limiting the pressure detection device 4 to prevent the pressure detection device 4 from being displaced by impact, thereby improving the impact resistance of the pressure detection device 4;

[0028] Then, the second screw 504 on the horizontal plate 502 is screwed. Since the second screw 504 is threadedly connected with the second screw barrel 503, the second screw 504 moves downward, so that the bottom wall of the bottom friction plate 505 is in close contact with the fixed friction plate 501. Therefore, under the action of friction force, the pressure detection device 4 can be fixed to the base 1, further improving the impact resistance of the pressure detection device 4.

[0029] After multiple pressure detection devices 4 are fixedly installed at predetermined positions, an impact operation is performed. Under the impact, the movable plate 405 moves downward, causing the sensing spring 407 to move downward and be compressed, and the sensing spring 407 presses on the pressure sensor 406, so that the pressure sensor 406 can detect the elastic force of the sensing spring 407, and the pressure distribution is detected through each pressure sensor 406.
