[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example

[0022] See also Figure 1-5 This utility model provides a technical solution: a device for testing the liquid penetration performance of chemical protective clothing;

[0023] This invention aims to provide a test device for the liquid penetration performance of chemical protective clothing that is easy to adjust, as existing tests for the liquid penetration performance of chemical protective clothing are inefficient.

[0024] Based on the above issues, the components in this case include a main body 1, a rectangular groove 2 evenly opened on the top of the main body 1, a storage box 3 corresponding to the position of the rectangular groove 2 on the rear side of the main body 1, a plug-in seat 4 on the front and rear sides of the rectangular groove 2, a clamping component plugged into the plug-in seat 4, a spiral frame 5 on the upper side of the rectangular groove 2, and the lower side of the spiral frame 5 connected to the inner wall of the rectangular groove 2 by screws.

[0025] The upper and lower sides of the spiral frame 5 are evenly provided with first nozzles 6, the lower side of the spiral frame 5 is equipped with a fixed frame 7, the inner side of the fixed frame 7 is evenly provided with second nozzles 8, the top of the storage box 3 is equipped with a delivery pump 9, the output end of the delivery pump 9 is connected to a three-way pipe 10, and the three-way pipe 10 is connected to the spiral frame 5 and the interior of the fixed frame 7 respectively.

[0026] The clamping assembly includes a connecting plate 11, a plug rod 12 that is plugged into the plug-in seat 4 is provided on the rear side of the connecting plate 11, a fixed seat 13 is provided at the front end of the connecting plate 11, a clamping seat 14 is slidably connected to the front end of the connecting plate 11, and clamping bolts 15 that are threadedly connected to the clamping seat 14 are inserted into both sides of the fixed seat 13.

[0027] It should be noted that during the liquid penetration test of the chemical protective suit, the operator can place the chemical protective suit horizontally and insert it between the fixing seat 13 and the clamping seat 14. Then, the clamping bolt 15 is used to drive the clamping seat 14 to rise, and the clamping block 18 is used to clamp and fix the chemical protective suit.

[0028] Simultaneously controlling the operation of the delivery pump 9 allows the liquid to be tested to be drawn from the storage box 3 and sent into the inside of the retractable frame 5 through the three-way pipe 10. Finally, it is sprayed out through several first nozzles 6, so that the liquid to be tested is evenly sprayed on the upper and lower sides of the chemical protective suit, thereby increasing the liquid penetration performance test of the chemical protective suit and ensuring the uniformity of liquid spraying.

[0029] Subsequently, the operator can rotate the insertion rod 12 and the connecting plate 11 by 90 degrees according to the usage requirements, and use the pin to fix the angle of the insertion rod 12 after rotation. At this time, the chemical protective suit remains vertical. The delivery pump 9 then draws the test liquid again and introduces the test liquid into the fixed frame 7, and finally sprays it out through the second nozzle 8. This allows for the evaluation of the protective suit's anti-penetration performance under gravity, increasing the test effect. The three-way pipe 10 is equipped with three corresponding solenoid valves, which facilitates the introduction of liquid into the U-shaped frame 5 or the fixed frame 7 respectively. This technology is existing technology and will not be described in detail.

[0030] In this technical solution, multiple sets of rectangular grooves 2 are set on the top of the main body 1. Different rectangular grooves 2 can uniformly spray different test liquids onto the surface of the chemical protective clothing, and the spraying process can be carried out simultaneously, resulting in high overall operating efficiency. At the same time, the chemical protective clothing can be tested in both horizontal and vertical states, resulting in good overall testing results.

[0031] Both sides of the top of the rectangular trough 2 are provided with baffles 16. The upper side of the spiral frame 5 is connected to the baffles 16 by screws to prevent the liquid to be tested from splashing. The front end of the rectangular trough 2 is provided with a control board 17 to control the electrical components inside the device. At the same time, the spiral frame 5 and the fixed frame 7 are not connected. The fixed frame 7 is fastened to the inside of the spiral frame 5.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
