Technical Field

[0001] This utility model relates to the field of bulletproof plate testing technology, and in particular to a bulletproof plate testing device. Background Technology

[0002] A bulletproof plate is a protective device primarily used to protect personnel from bullets, shrapnel, and other projectiles. By simulating real-world shooting scenarios, the bulletproof performance of bulletproof plates under different firing conditions is tested to determine parameters such as the type, velocity, and energy of bullets they can withstand, providing a basis for the quality assessment and application of bulletproof plates.

[0003] Chinese Patent No. CN219977229U discloses a fixing device suitable for testing the ballistic performance of ballistic products of various sizes. The device includes a base plate, a main frame, a width clamping assembly, and a first thickness clamping assembly. The main frame includes at least two parallel vertical beams and a horizontal beam. The width clamping assembly is slidably connected to the horizontal beam. The clamping column in the width clamping assembly has a first slot for clamping the ballistic product. The first thickness clamping assembly is located within the first slot and its position within the first slot is adjusted by a second locking assembly. This device, through the adjustment of the width clamping assembly, enables the clamping of ballistic products of different widths. The first thickness clamping assembly stably clamps and fixes the ballistic product within the width clamping assembly. This allows the fixing device for ballistic products in this application to meet the clamping and fixing functions of ballistic products of various widths, expanding the diversity of ballistic product performance testing. Simultaneously, the clamping edge distance and exposed dimensions of the tested ballistic product can be adjusted.

[0004] However, the above technical solution has the following shortcomings: when clamping and fixing the bulletproof plate, the device needs to tighten a large number of threaded fasteners, which not only involves a large amount of work, but also results in a generally poor fixing effect, reducing the ease of use of the device. Utility Model Content

[0023] Example 1

[0024] like Figures 1-6 As shown, the bulletproof plate testing device proposed in this embodiment includes a base 1 and a stabilizing device; a fixing block 2 and a support frame 5 are provided on the base 1, and a reinforcing abutment 26 is provided on the fixing block 2 to improve the resistance of the fixing block 2.

[0025] The stabilizing device includes a motor 6 mounted on a support frame 5, a rotating shaft 7 rotatably connected to the support frame 5 and having two symmetrically distributed threaded portions 8, two moving blocks 9 threaded to the threaded portions 8, a guide block 10 and a connecting rod 11 mounted on the moving blocks 9, a frame 12 mounted on the connecting rod 11, and a clamping mechanism mounted on the frame 12; the motor 6 and the rotating shaft 7 are driven together, the two threaded portions 8 have opposite thread directions, and the guide block 10 is slidably mounted inside the support frame 5; the clamping mechanism includes a threaded rod 13 threaded to the frame 12, two guide rods 14 slidably connected to the frame 12, a pressure plate 15 mounted on the guide rods 14, and a rotating connector 16 mounted on the pressure plate 15; one end of the threaded rod 13 is rotatably connected to the rotating connector 16, and the other end of the threaded rod 13 is provided with a handwheel 17.

[0026] A base plate 3 is slidably connected to the base 1, and a rectangular hole for the base plate 3 to pass through is provided on the fixing block 2. A fixing bolt 4 is threadedly connected to the base 1, and an oblong hole for the fixing bolt 4 to pass through is provided on the base plate 3.

[0027] In this embodiment, when it is necessary to fix the bulletproof plate, the bottom of the bulletproof plate is first placed on the base plate 3 and attached to the fixing block 2. Then, the motor 6 is started to drive the rotating shaft 7 to rotate, so that the two threaded parts 8 are respectively threaded with the moving blocks 9 on both sides. Under the guidance of the guide block 10, the moving blocks 9 on both sides will drive the connecting rod 11 and the frame 12 to move closer to each other until the frame 12 and the sides and corners of the bulletproof plate abut. Then, the threaded rod 13 is rotated by the handwheel 17, and the threaded rod 13 and the frame 12 are threaded together. Under the guidance of the guide rod 14, the end of the threaded rod 13 rotates with the rotating connector 16 and pushes the pressure plate 15 to move until the pressure plate 15 presses tightly on the bulletproof plate. Finally, the base plate 3 is pushed to abut against the bottom of the bulletproof plate and the fixing bolt 4 is screwed into the interior of the base 1 after passing through the waist-shaped hole. This completes the fixing operation of the bulletproof plate, which greatly reduces the number of threaded fasteners used and has a good fixing effect. It avoids the situation where the fixing contact parts are easily damaged and has good practicality.

[0028] Example 2

[0029] like Figure 3 and Figure 4 As shown, the bulletproof plate testing device proposed in this embodiment, compared with the first embodiment, has an installation block 18 on the frame 12, a T-shaped locking block 19 on the installation block 18, and a sliding groove for the locking block 19 to slide on the fixing block 2. The frame 12 and the fixing block 2 are slidably connected, and the frame 12 and the upper corner of the bulletproof plate abut against each other. When the frame 12 moves closer to the bulletproof plate, it will drive the installation block 18 to move. The installation block 18 drives the locking block 19 to move and then fixes the inside of the sliding groove on the fixing block 2, thereby improving the fastening effect on the bulletproof plate.

[0030] Example 3

[0031] like Figure 1 and Figure 6 As shown, the bulletproof plate testing device proposed in this embodiment, compared with the first embodiment, has a reinforcement component on the base 1. The reinforcement component includes two upright blocks 20 symmetrically distributed on the base 1, a slide rod 21 slidably connected to the upright blocks 20, an abutment block 22 set on the slide rod 21, and a spring 23 with its two ends respectively set on the upright blocks 20 and the abutment block 22. A slider 24 is set on the abutment block 22, and a guide groove is set on the base 1 for the slider 24 to slide horizontally.

[0032] The slide bar 21 is provided with a positioning hole 25, and the upright block 20 is provided with a through hole.

[0033] In this embodiment, after the bulletproof plate is fixed, the pin (not shown) is pulled out from the through hole on the upright block 20, so that the pin is disengaged from the positioning hole 25 on the slide rod 21. Since the slide rod 21 loses its restrictive function, the elastic force of the compressed spring 23 will push the abutment block 22 to move. Then, under the guidance of the slider 24 and the guide groove, the abutment block 22 moves closer to the bulletproof plate until it abuts against the bottom corner of the bulletproof plate, thereby further improving the stability of the bulletproof plate and making the operation simple.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
