[0031] See also Figure 1-Figure 5The embodiment of the present invention provides: a local protection device for explosion injury for experiment, comprising: an experimental platform 1, a protective member 2 and a sealing mechanism 3; an experimental animal is placed on the experimental platform 1; the protective member 2 comprises: a crossbar 21 and a side block 22; both ends of the crossbar 21 are respectively provided with side blocks 22 which are perpendicular to the crossbar 21; and one end of the side block 22 is fixedly connected to the crossbar 21, and the other end of the side block 22 is slidably installed on the experimental platform 1, and the protective member 2 and the experimental platform 1 enclose a protective cavity with two ends connected to cover the local part of the experimental animal; the two ends of the protective cavity are respectively installed with sealing mechanisms 3 to seal the two ends of the protective cavity through the sealing mechanism 3.

[0032] During the specific implementation, the experimental animal is placed on the experimental table 1, and then tied and fixed; then the protective member 2 is slid so that the protective member 2 covers the local position of the experimental animal that needs protection, so that the cross bar 21 protects the top of the experimental animal, and the two side blocks 22 protect the two sides of the experimental animal; then the sealing mechanism 3 is controlled to act, and the sealing mechanism 3 seals the protective cavity to seal the gap between the experimental animal and the protective member 2, so as to prevent the shock wave generated during the explosion from entering the local position that needs protection; in this way, the local protection of the experimental animal can be completed, thereby improving the accuracy of data and results when conducting explosion injury experiments; and by sliding the side blocks 22, the position of the protective member 2 can be adjusted to achieve local protection of different positions of the experimental animal, which greatly improves the adaptability of the device.

[0033] See also Figure 1-Figure 5 In other embodiments, the sealing mechanism 3 includes a plurality of plug-in plates 31; the plurality of plug-in plates 31 are located in the same plane, the plurality of plug-in plates 31 are slidably plugged into the cross piece 21 in sequence, and two adjacent plug-in plates 31 are slidably abutted against each other, and the plug-in plates 31 are perpendicular to the cross piece 21 and the side block 22.

[0034] During specific implementation, the plug board 31 is slid so that one end of the plug board 31 abuts against the body of the experimental animal. In this way, by setting up multiple plug boards 31, the two ends of the protective cavity can be blocked, thereby realizing local protection of the experimental animal; and by adjusting the height position of different plug boards 31, it can be suitable for the protection of different positions of the experimental animal, thereby greatly improving the adaptability of the device.

[0035] See also Figure 1-Figure 5In other embodiments, a limiting mechanism 4 is also included, and the limiting mechanism 4 corresponds to the sealing mechanism 3 one by one, and the limiting mechanism 4 can limit the sliding position of multiple plug-in boards 31. By limiting the multiple plug-in boards 31 through the limiting mechanism 4, it is possible to prevent the plug-in boards 31 from accidentally sliding and leaking the local position that needs to be protected. Further, the limiting mechanism 4 includes: a base 41, an elastic rod 42 and a limiting block 43; a groove 32 is opened in the length direction of the plug-in board 31, and a plurality of triangular limiting grooves 33 are respectively opened on the opposite sides of the inner side wall of the groove 32, and the plurality of triangular limiting grooves 33 are arranged along the length direction of the plug-in board 31; one end of the plurality of elastic rods 42 is fixedly mounted on the base 41; the other end of the plurality of elastic rods 42 is fixed with a limiting block 43; each groove 32 corresponds to two limiting blocks 43 and an elastic rod 42; the two limiting blocks 43 correspond to the triangular limiting grooves 33 on both sides of the groove 32, and the elastic rod 42 cooperates with the triangular limiting grooves 33.

[0036] During specific implementation, the base 41 is installed on the cross piece 21, and the limit block 43 is inserted into the corresponding triangular limit groove 33 through the elastic rod 42, and the two limit blocks 43 effectively limit the plug-in board 31; when it is necessary to slide the plug-in block, press the corresponding plug-in board 31 with force, and the limit block 43, under the guidance of the inclined surface of the triangular limit groove 33, applies a thrust away from the triangular limit groove 33 to the elastic rod 42, so that the elastic rod 42 bends toward the side away from the triangular limit groove 33, and the limit block 43 slides out of the triangular limit groove 33 and slides to the next triangular limit groove 33.

The tightening block 44 is slidably abutted against the two elastic rods 42. In specific implementation, after the limiting block 43 is clamped to the corresponding triangular limiting groove 33, the tightening block 44 is slid so that the tightening block 44 moves toward the plug-in board 31, and the tightening block 44 moves into the groove 32 on the plug-in board 31, so that the two limiting blocks 43 can be pressed against the triangular limiting groove 33 by the two elastic rods 42, thereby preventing the limiting blocks 43 from sliding out of the triangular limiting groove 33. Furthermore, the side of the limiting rod away from the limiting block 43 is provided with an inclined surface 45 that gradually thickens toward the plug-in board 31. When the abutting block 44 moves toward the plug board 31 , under the guidance of the inclined surface 45 , the two limiting blocks 43 can be pressed more tightly in the triangular limiting groove 33 .

[0038] See also Figure 1-Figure 5In other embodiments, an elastic band 46 is further included, one end of the elastic band 46 is hinged to one end of the inclined surface 45 close to the plug board 31 , and the other end of the elastic band 46 is fixedly connected to the tightening block 44 . During specific implementation, the elastic band 46 applies a direction to the clamping block 44, and the elastic force of the elastic band 46 pulls the clamping block 44 to move toward the groove 32 on the plug-in board 31, so as to clamp the two limit blocks 43 in the triangular limit groove; and when it is necessary to adjust the height of the plug-in board 31, the clamping block 44 is pulled in the opposite direction, and the clamping block 44 slides out of the groove 32, and stops clamping the two limit blocks 43; then continue to slide the clamping block 44, and the clamping block 44 applies a torque to the elastic rod 42 through the elastic band 46 and the inclined surface 45, so that the elastic rod 42 bends toward the side away from the triangular limit groove 33, thereby moving the limit block 43 on the elastic rod 42 out of the triangular limit groove 33, so that there is no need to press the plug-in board 31, so that the plug-in board 31 can be in contact with the body of the experimental animal under the action of its own gravity, which greatly simplifies the operation steps for sealing the protective cavity.
