The salt spray test chamber continuously sprays through the spray tower In the simulated test environment, the spray is performed according to the set time during the test. The salt mist is first deposited into the inner cylinder 13 through the funnel 14. When the inner cylinder 13 is almost full, it flows into the outer cylinder 9 through the rectangular opening 15 at the upper end of the inner cylinder 13 to continue to deposit. After the spraying is completed, the volume and weight of the salt mist deposition are tested. The outer cylinder 9 is provided with a scale line to facilitate the rapid measurement of the volume of the salt solution deposited in the inner cylinder 13 and the outer cylinder 9. Since the inner cylinder 13 is narrow, the volume of the deposited salt solution can be accurately measured even in the case of a short spray time, thereby improving the accuracy of the salt spray deposition test. After the volume measurement is completed, the inner cylinder 13 and the outer cylinder 9 are removed for weight testing. After calculation based on the test results, the accurate salt spray deposition can be calculated.

[0024] A rubber pad 20 is bonded to the bottom of the sealing plate 18, and a buffer seat 11 is fixedly connected to the bottom end of the outer cylinder 9. The rubber pad 20 and the buffer seat 11 provide buffer protection when the inner cylinder 13 touches the outer cylinder 9 and when the outer cylinder 9 touches the L-shaped bracket 1 during the salt spray deposition test, thereby avoiding direct collision and causing wear of components.

[0025] The outer wall of the L-shaped bracket 1 is fixedly connected with a fixing piece 2, the inner wall of the L-shaped bracket 1 is provided with a limiting groove 3, the inner wall of the L-shaped bracket 1 is fixedly connected with a vertical rod 4, the vertical rod 4 is located on the inner side of the limiting groove 3, the inner wall of the limiting groove 3 is slidably connected with a moving block 6, the outer wall of the moving block 6 is slidably connected to the inner wall of the limiting groove 3, the outer wall of the auxiliary frame 5 is fixedly connected to the outer wall of the moving block 6, the inner wall of the auxiliary frame 5 is fixedly connected with a spring 12, the bottom end of the spring 12 is against the bottom of the inner wall of the L-shaped bracket 1, and the fixing piece is used. 2. The L-shaped bracket 1 can be fixed inside the salt spray test chamber. After being fixed, the auxiliary frame 5 is installed on the L-shaped bracket 1 through the moving block 6. The spring 12 provides an upward elastic force for the auxiliary frame 5. When the salt spray gradually passes through the funnel 14 and is deposited in the inner cylinder 13 and the outer cylinder 9, the weight borne by the auxiliary frame 5 increases synchronously, causing the spring 12 to be compressed. At this time, the height of the auxiliary frame 5 descending can be observed by observing the scale line on the L-shaped bracket 1, so as to understand the deposition of the salt spray in real time.

[0026] The upper and lower ends of the auxiliary frame 5 are fixedly connected to the limit ring 7. The inner wall of the upper limit ring 7 is provided with a groove 8. The outer wall of the outer cylinder 9 is fixedly connected with a fixing ring 21. The fixing ring 21 is located at the upper end of the outer cylinder 9. The outer cylinder 9 is clamped with the inner wall of the groove 8. The auxiliary frame 5 and the limit ring 7 provide installation support for the outer cylinder 9. The outer cylinder 9 realizes the limiting effect by clamping the fixing ring 21 on its outside with the groove 8.

[0027] Working principle: Before the test, fix the L-shaped bracket 1 inside the salt spray test chamber through the fixing piece 2, then install the auxiliary frame 5 on the L-shaped bracket 1, clamp the outer cylinder 9 into the inner limit ring 7, and then insert the inner cylinder 13 into the inner cylinder 9. After insertion, the inner cylinder 13 and the outer cylinder 9 form a simple installation. After the temperature of the salt spray test chamber rises to the specified temperature, the spray tower is used to continuously spray the simulated test environment. The salt mist is deposited into the inner cylinder 13 through the funnel 14. When the inner cylinder 13 is almost full, the inner cylinder 13 is opened through the rectangular opening at the upper end of the inner cylinder 13. 15 flows into the outer cylinder 9 to continue to deposit. After the spraying is completed, the volume and weight of the salt mist deposition are tested. The outer cylinder 9 is provided with scale lines, which are convenient for quickly measuring the volume of the salt solution deposited in the inner cylinder 13 and the outer cylinder 9. Since the inner cylinder 13 is narrow, the volume of the deposited salt solution can be accurately measured even under a short spraying time, thereby improving the accuracy of the salt mist deposition test. After the volume measurement is completed, the inner cylinder 13 and the outer cylinder 9 are removed for weight testing. After calculation, the salt mist deposition can be accurately obtained.

[0028] 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.
