[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0039] like Figure 1-Figure 3 As shown, the present application provides a protective clothing liquid tightness tester, including a test box 1, which is filled with test liquid. A test dummy 4 is arranged in the test box 1, and the test dummy 4 is made of foam material, which is convenient for the operator to move. Therefore, during the test, the protective clothing to be tested is put on the test dummy 4, and a placement plate 12 is arranged in the test box 1, and the placement plate 12 is used to place the test dummy 4. In the present application, the placement plate 12 and the test dummy 4 are completely immersed in the test liquid in the test box 1 under normal conditions.

[0040] In order to conveniently control the position of the test dummy 4 and take out or immerse the test dummy 4 into the test liquid in the test box 1, an adjustment mechanism 2 is provided at the lower end of the placement plate 12. The adjustment mechanism 2 is used to adjust the height of the placement plate 12. The adjustment mechanism 2 has a base 21, which is fixedly installed at the inner bottom end of the test box 1. The upper end of the base 21 is rotatably connected to a support rod 22. At the same time, a slide groove 13 is provided on the placement plate 12, and the support rod 22 is slidably connected in the slide groove 13.

[0041] A movable rod 23 is rotatably connected to the placement plate 12, and the movable rod 23 crosses and is movably connected to the support rod 22. A sliding assembly 3 is also installed on the upper end of the base 21, and the movable rod 23 is installed on the sliding assembly 3. The position of the lower end of the movable rod 23 is controlled by the sliding assembly 3, so that the support rod 22 slides in the slide groove 13.

[0042] The sliding assembly 3 includes a baffle 31 fixed on the base 21, and a bearing seat 32 is fixedly installed on the upper end of one side of the base 21. The bearing seat 32 is fixed to one side of the test box 1. A screw 33 is rotatably connected inside the bearing seat 32. In the present application, a leak-proof sealing device is provided at the connection between the screw 33 and the test box 1, so as to ensure that the test liquid in the test box 1 will not leak out through the connection end of the screw 33;

[0043] The end of the screw rod 33 away from the bearing seat 32 is rotatably connected to the baffle 31, and a slider 34 is meshed and connected to the screw rod 33. Connecting columns 35 are fixedly installed at both ends of the slider 34. The end of the connecting column 35 away from the slider 34 is rotatably connected to the bottom of the movable rod 23. Therefore, by rotating the screw rod 33, the slider 34 can slide left and right on the screw rod 33, so that the movable rod 23 is driven to move through the connecting column 35, so that the support rod 22 slides in the slide groove 13. At this time, the movable rod 23 and the support rod 22 can be relatively rotated to adjust the height of the placement plate 12.

[0044] In order to improve the sliding stability of the slider 34, a sliding rod 36 is fixedly installed between the bearing seat 32 and the baffle 31. The sliding rod 36 is arranged on both sides of the screw rod 33 and penetrates the connecting column 35. Therefore, when the slider 34 slides on the screw rod 33, the connecting column 35 also slides on the sliding rod 36 at the same time, thereby ensuring the sliding stability of the slider 34.

[0045] A gripping portion 37 is provided at the outer end of the screw rod 33 , and the operator controls the height of the adjustment mechanism 2 by manually rotating the gripping portion 37 . In the present application, the operator may also provide a driving motor at the gripping portion 37 for driving.

[0046] In order to prevent the test dummy 4 from sliding off the placement plate 12, a protective mechanism 5 is further installed at the upper end of the placement plate 12. The protective mechanism 5 has a fixing plate 51 fixed to one side of the placement plate 12. A groove (not shown in the figure) is provided at the upper end of the fixing plate 51. A protective belt 52 is rotatably connected in the groove. The protective belt 52 is set as an elastic structure and can be deformed as it is pulled. A hook 55 is fixedly installed at one end of the protective belt 52 away from the fixing plate 51.

[0047] At the same time, two groups of pillars 53 are fixedly installed on the other side end of the placement plate 12. The pillars 53 are arranged opposite to the fixed plate 51, and a fixing rod 54 is fixedly installed between the two groups of pillars 53. The fixing rod 54 and the hook 55 cooperate with each other. Therefore, when the test dummy 4 is placed on the placement plate 12, the operator manually pulls the hook 55 to deform the protective belt 52 until the hook 55 is stuck on the fixing rod 54, thereby wrapping the protective belt 52 around the top of the test dummy 4 to protect the test dummy 4.

[0048] In the present application, the height of the fixing plate 51 and the support 53 is higher than the thickness of the test dummy 4 , thereby preventing the protective belt 52 from being closely attached to the test dummy 4 and affecting the test of the protective clothing.

[0049] A water outlet 11 is provided at one side of the bottom end of the test box 1 , through which the test liquid in the test box 1 can be discharged.

[0050] In summary, when testing the protective clothing, the protective clothing to be tested is firstly put on the test dummy 4, and a water-absorbent indicator garment is put between the test dummy 4 and the protective clothing, and then it is placed on the placement plate 12 and protected by the protection mechanism 5. Then the operator manually rotates the gripping portion 37 to rotate the screw 33, and adjusts the movable rod 23 and the support rod 22 to contract and open, so that the placement plate 12 is downward, and the test dummy 4 is completely immersed in the interior of the test box 1, and then it is kept still for a period of time to observe whether the protective clothing on the test dummy 4 is bubbling. If there is bubbling, it is unqualified. Finally, the placement plate 12 is adjusted upward to push the test dummy 4 out of the water surface in the test box 1, and then observe whether there is liquid immersed in the water-absorbent indicator garment. If not, it is determined to be a qualified product, thereby completing the liquid tightness test of the protective clothing, preventing waste of the sprayed liquid raw material, and ensuring that the test liquid can penetrate the unqualified protective clothing, thereby improving the test efficiency and quickly judging whether the protective clothing is qualified.

[0051] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
