In order to ensure that the aerosol can has good sealing, it is often necessary to detect the leakage of the aerosol can.

[0003] Existing aerosol can leakage detection devices generally detect the leakage of aerosol cans through liquid. The aerosol can is placed in water and the air tightness of the aerosol can is determined by observing whether bubbles emerge from the aerosol can. However, this method has the problems of being difficult to quickly replace the aerosol can and to place the aerosol can firmly in the water, and the test efficiency is low. At the same time, it is difficult to accurately find the leakage location and it is difficult to determine the gas leakage amount by the gas leakage speed. [Contents of the utility model]

[0021] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one of the features.

[0023] like Figure 1-3 As shown, a fixture for visually detecting leakage of an aerosol can includes a water tank 1, a detachable fixture fixing frame 2 is provided in the water tank 1, a first movable clamp 3 and a second movable clamp 4 with adjustable positions are provided on the fixture fixing frame 2, the first movable clamp 3 clamps the aerosol can vertically and immerses the aerosol can in water, and the second movable clamp 4 clamps a container detection tube 5 with one end closed and filled with water and an opening cover body closed on the upper side of the aerosol can for collecting leaked gas to detect whether the aerosol can leaks. During the detection, the aerosol can is clamped on the fixture fixing frame 2 by the first movable clamp 3, and the container detection tube 5 is clamped on the fixture fixing frame 2 by the second movable clamp 4 and the opening cover of the container detection tube 5 is closed on the top of the aerosol can, then the fixture fixing frame 2, the aerosol can and the container detection tube 5 are placed in the water tank 1 together, and after the container detection tube 5 is filled with water, the fixture fixing frame 2 is vertically fixed in the water tank 1. When a leak occurs, the leaked gas enters the container detection tube 5, through which the leak position can be visually found and the amount of gas leakage can be detected, thereby realizing the function of quickly replacing the aerosol can and firmly clamping it in the water tank 1. By checking the amount of gas leakage in the container detection tube 5, it is convenient to improve the aerosol can production process.

[0024] like Figure 1-3 As shown, the container detection tube 5 includes a cover body 51 for clamping by the second movable clamp 4 and covering the upper side of the aerosol can. The outer side of the cover body 51 is provided with a first branch pipe 52 connected to the inner cavity of the cover body 51, and a second branch pipe 53 with an open end passing through the inner cavity of the cover body 51 and covering the opening of the aerosol can. When gas leaks from the side or bottom of the aerosol can, the leaked gas enters the first branch pipe 52 and is collected; when gas leaks between the aerosol can mouth and the aerosol valve or from the aerosol valve, the leaked gas enters the second branch pipe 53 and is collected. At this time, the gas leakage position of the aerosol can can be determined by checking the collected gas of the branch pipe, which is convenient for improving the aerosol can production process according to different gas leakage points.

[0025] like Figure 1-3 As shown, numerical scales are respectively provided on the outer side surfaces of the first branch pipe 52 and the second branch pipe 53, so that the gas leakage amount at the leakage point of the aerosol can can be visually checked, thereby optimizing the production process.

[0026] like Figure 1-2 As shown, a support block 6 for supporting the aerosol can is provided on the fixture fixing frame 2. By supporting the bottom of the aerosol can by the support block 6, the aerosol can can be steadily immersed in the water tank 1, thereby improving the accuracy of gas leakage detection.

[0027] like Figure 1-3 As shown, the water tank 1 is a constant temperature heating water tank. Constant temperature heating is used to simulate the use of the aerosol can in a high temperature environment, so as to realize the changes of the aerosol can in a high temperature state and detect the gas leakage, thereby shortening the inspection cycle of the aerosol can; Figure 1-2 As shown, a water tank partition 8 is provided at the bottom of the water tank 1, and a plurality of water tank through holes 81 are provided on the water tank partition 8. A water inlet and outlet hole 11 is provided on the side of the water tank 1, and a heating pipe of the constant temperature heating water tank is arranged in the water tank partition 8. In this case, water is injected into or discharged from the water tank 1 through the water inlet and outlet hole 11; when the constant temperature heating water tank is heated, the heating pipe arranged inside the water tank partition 8 heats the water.

[0028] like Figure 1-2 As shown, in this case, the first movable clamp 3 and the second movable clamp 4 can cover the full-size aerosol cans with a caliber of 25.4, and can clamp the aerosol can products with a diameter of 22mm-66mm. An adjustable clamp 7 is provided between the support bracket 6 and the clamp fixing frame 2; an adjustable clamp 7 is provided between the first movable clamp 3 and the clamp fixing frame 2, and between the second movable clamp 4 and the clamp fixing frame 2. The first movable clamp 3, the second movable clamp 4 and the support bracket 6 are fixed to the clamp fixing frame 2 by the adjustable clamp 7, and the positions of the first movable clamp 3, the second movable clamp 4 and the support bracket 6 on the clamp fixing frame 2 can be adjusted up and down by the adjustable clamp 7, so that the detection fixture is suitable for detecting aerosol cans of different heights.

[0029] like Figure 1-2 As shown, the fixture fixing frame 2 includes an H-shaped bottom frame 21 disposed in the water tank 1, two vertically disposed fixture support rods 22 are disposed on the H-shaped bottom frame 21, a handle 23 is disposed between the two fixture support rods 22, and a first movable clamp 3, a second movable clamp 4 and a support bracket 6 are respectively disposed on the fixture support rods 22 and their positions are adjusted by an adjustable clamp 7. In this case, two aerosol cans can be tested for airtightness at the same time, and the fixture fixing frame 2 can be easily taken out of the water tank 1 by providing the handle 23.

[0030] like Figure 1-2As shown, the adjustable clamp 7 includes a jacket 71 sleeved on the clamp fixing frame 2, a screw 72 having one end pressed against the clamp fixing frame 2 to fix the jacket 71 on the clamp fixing frame 2, and an elastic clip 73 is provided on the jacket 71. When in use, the jacket 71 is sleeved on the clamp fixing frame 2, and the jacket 71 is fixed by screws after adjusting the position, so as to adjust the position of the first movable clamp 3, the second movable clamp 4 and the support bracket 6 on the clamp fixing clamp 2.

[0031] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
