[0002] Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material composition, and physical property parameters. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc., all belong to instruments and meters. In a broader sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission, and data processing. Most instruments and meters have certain requirements for waterproofing, especially those used with liquids. Therefore, after the instruments and meters are manufactured, they need to undergo waterproof testing.

[0003] Some instruments require both spray and immersion tests. The spray test assesses the instrument's performance under rain or moisture, while the immersion test simulates its adaptability to underwater environments. The typical procedure involves first placing the instrument in the spray test equipment, then manually removing it and transferring it to the immersion test equipment. This transfer process not only extends the testing cycle and reduces overall testing efficiency but also increases the workload of the operators. Utility Model Content

A connecting shaft 3 is connected to the middle of the front side of the inner wall of the immersion tank 1 near the top via a bearing. A support plate 4 is fixedly sleeved on the middle of the surface of the connecting shaft 3. Clamping components 5 are fixedly connected to the top and bottom surfaces of the support plate 4. A first through hole is opened in the middle of the rear side of the immersion tank 1 near the top. The rear bearing of the connecting shaft 3 is sleeved in the first through hole and extends to the outside of the rear side of the immersion tank 1. A motor 6 is fixedly connected to the top of the frame via a frame. The shaft of the motor 6 is fixedly connected to the rear end face of the connecting shaft 3. A first connecting pipe 7 is fixedly sleeved in the middle of the top of the connecting frame 2. A spray head 8 is fixedly connected to the lower end of the first connecting pipe 7. A water pump 9 is fixedly connected to the right side of the top of the connecting frame 2. One end of the first connecting pipe 7 is fixedly connected to the water inlet of the water pump 9. A second connecting pipe 10 is fixedly connected to the water outlet of the water pump 9. One end of the second connecting pipe 10 is fixedly connected to the bottom of the left side of the soaking tank 1 and extends through the inner cavity.

[0024] In order to clamp and fix the instrument, the clamping assembly 5 includes a connecting plate 51, which is fixedly connected to the support plate 4. A screw 52 is connected to the bearing on the left side of the inner wall of the connecting plate 51. Both ends of the screw 52 are threadedly connected to the first clamping plate 53. A second through hole is opened on the right side of the screw 52. The bearing on the right end of the screw 52 is sleeved in the second through hole and extends to the outside of the right side of the connecting plate 51. A torsion handle 54 is fixedly connected to the right end face of the screw 52.

[0025] In order to allow one end of the first clamping plate 53 to extend through the outside of the connecting plate 51 and to restrict the first clamping plate 53 so that it does not move with the screw 52, ​​the connecting plate 51 has movable openings 55 on both the left and right sides away from the support plate 4. One end of the two first clamping plates 53 is slidably connected in the adjacent movable openings 55 and extends through the outside of the connecting plate 51.

[0026] In order to clamp and fix the first clamping plate 53 from the top, which not only improves the stability of the instrument after clamping, the two first clamping plates 53 are fixedly connected to the facing surfaces and the side away from the connecting plate 51 with connecting blocks 56. The middle of the connecting block 56 is threaded with a bolt 57, and the end face of the bolt 57 near the connecting plate 51 is connected to a second clamping plate 58.

[0027] In order to filter the water drawn into the second connecting pipe 10 and prevent impurities in the water from being drawn in, a filter screen 11 is fixedly connected to the right side of the inner wall of the soaking tank 1 near the bottom, and the right side of the filter screen 11 is in contact with the water inlet end of the second connecting pipe 10.

[0028] To facilitate the drainage of water from the soaking tank 1, a drain pipe 12 is fixedly connected to the middle of the front side of the soaking tank 1, and a butterfly valve 13 is installed on the drain pipe 12.

[0029] To facilitate the operation of the electrical structure on the control device and to time the spraying and soaking time of the instrument, a control panel 14 is fixedly connected to the left side of the surface of the connecting frame 2, and a timer indicator 15 is fixedly connected to the left side of the top of the connecting frame 2. The control panel 14 is electrically connected to the motor 6, the water pump 9 and the timer indicator 15.

[0030] For this purpose, the front hinge of the connecting frame 2 is connected to the door 16, and the middle of the door 16 is fixedly nested with an observation window 17, and a transparent glass plate is fixedly nested inside the observation window 17.

[0031] Working Principle: When using this invention, first fill the soaking tank 1 with water. After filling, place the instrument on the upper connecting plate 51. Then, turn the torsion handle 54 to rotate the screw 52. The rotation of the screw 52 causes the two first clamping plates 53 to move towards each other, clamping the instrument from the left and right sides. Then, turn the bolt 57 to lower the second clamping plate 58, clamping the instrument from the top. Next, start the water pump 9 via the control panel 14. The water pump 9 draws water from the soaking tank 1 through the second connecting pipe 10 and discharges it into the spray head 8 through the first connecting pipe 7. The spray head 8 sprays water to test the instrument. After the spraying time is reached, the timer 15 alerts the operator, and the spray head 8 stops spraying water. Then, the operator observes and inspects the instrument. After the test is completed and the device is started, the control panel 14 controls the motor 6 to start. The motor 6 drives the connecting shaft 3 to rotate, which in turn drives the support plate 4 to rotate. The support plate 4 then drives the clamping assembly 5 to rotate. The clamping assembly 5, which was originally on the upper side, rotates into the immersion tank 1, immersing the instrument in the water in the immersion tank 1. This allows the device to perform both spray and immersion tests on the instrument. There is no need to transfer the instrument when switching between the two tests, making the test more time-saving and labor-saving. The clamping assembly 5, which was originally on the lower side, rotates to the inside of the connecting frame 2. Then, another instrument is taken and clamped and fixed on the clamping assembly 5, and water is sprayed onto the instrument for a spray test. At this time, the two instruments are sprayed and immersed for tests respectively. The device can perform waterproof tests on two instruments simultaneously, thereby improving the testing efficiency of the instruments.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
