[0028] Please see Figures 1-3 As shown, this utility model is a waterproof testing device for instrument manufacturing, including a barrel 1. A test chamber 3 is fixedly installed on the top of the inner cavity of the barrel 1. A placement opening is provided on the top of the barrel 1. A fixing mechanism 4 is fixedly installed on the bottom of the barrel 1. An instrument body 2 is placed on the top of the fixing mechanism 4. Specifically, water for testing the instrument body 2 is injected into the inner cavity of the test chamber 3 so that the test chamber 3 can test the waterproof performance of the instrument body 2. The testing method can be referred to in the reference documents cited in this application.

[0029] Please see Figure 2 and Figure 3 As shown, a motor 41 is fixedly installed at the bottom of the barrel 1, and an arc-shaped guide rail 42 is fixedly installed at the output end of the motor 41. A spring 45 is movably sleeved on the bottom of the outer wall of the push rod 44, and the spring 45 is located at the bottom of the test box 3. A steel ball 43 is slidably connected to the bottom of the push rod 44, and the outer wall of the steel ball 43 is slidably connected to the top of the arc-shaped guide rail 42.

[0030] The rotation of the arc-shaped guide rail 42 by the motor 41 causes the bottom of the push rod 44 to slide on the top of the arc-shaped guide rail 42, thereby pushing the push rod 44 upward and pushing the support plate 48 to the position of the instrument body 2 at the top of the inner cavity of the test chamber 3. The spring 45 pushes the push rod 44 downward to push the support plate 48 to the bottom of the inner cavity of the test chamber 3, moving the instrument body 2 placed on the cross support plate 416 to the bottom of the inner cavity of the test chamber 3 or pushing it out of the inner cavity of the test chamber 3, so that the test chamber 3 can perform waterproof performance testing on the instrument body 2 that has entered the bottom of the inner cavity.

[0031] Please see Figures 1-6As shown, the fixing mechanism 4 includes a push rod 44 that is movably sleeved with the bottom of the test chamber 3. A support plate 48 is fixedly installed on the top of the push rod 44. A bracket is fixedly connected to the upper surface of the support plate 48. A lever arm 49 is rotatably connected to the top of the bracket. A cross support plate 416 is fixedly connected to the middle of the upper surface of the lever arm 49. A guide rail 46 is fixedly connected to the inner wall of the test chamber 3. The inner wall of the guide rail 46 is slidably connected to one end of the lever arm 49, and the guide rail 46 is J-shaped. A ball head 412 is fixedly installed at the other end of the lever arm 49. A pressure plate 47 is movably connected to the outer wall of the ball head 412, allowing the pressure plate 47 to rotate at a certain angle on the outer wall of the ball head 412, so that the bottom of the pressure plate 47 can better fit against the top of the instrument body 2; an arc-shaped guide rod 414 is movably sleeved on the top of the bracket, one end of the arc-shaped guide rod 414 is fixedly connected to the lever arm 49, and a spring 413 is movably sleeved on the outer wall of the arc-shaped guide rod 414, with the spring 413 located between the bracket and the lever arm 49; a limit ring 410 is movably sleeved at the edge of the support plate 48, limiting... A guide rod 415 is fixedly connected to the bottom of the positioning ring 410. The outer wall of the guide rod 415 is movably sleeved with the edge of the support plate 48. A spring 411 is movably sleeved at the top of the outer wall of the guide rod 415, and the spring 411 is located between the positioning ring 410 and the support plate 48, generating an upward thrust on the positioning ring 410, thus enclosing the instrument body 2 inside the positioning ring 410. The inner diameter of the positioning ring 410 is slightly larger than the outer diameter of the instrument body 2. Specifically, the inner diameter of the positioning ring 410 is slightly larger than the outer diameter of the instrument body 2. The spacing between the two is 1cm to facilitate the placement of the instrument body 2 and prevent it from falling off due to instability in the inner cavity of the limiting ring 410, which would affect the waterproof test effect of the instrument body 2. In addition, the outer edge of the top of the limiting ring 410 is slightly larger than the diameter of the placement opening. The limiting ring 410, which is moved to the top support plate 48 of the test box 3, is pushed downward to release the limiting ring 410 from the instrument body 2, so that the instrument body 2 can be easily removed from the cross support plate 416.

[0032] By moving the push rod 44 upward, one end of the lever arm 49 slides inside the guide rail 46, causing the lever arm 49 to rotate on top of the bracket. The other end of the lever arm 49 rotates upward, releasing the pressure plate 47 from fixing the instrument body 2 after the test. At the same time, the limiting ring 410 will block the edge of the top of the limiting ring 410 at the placement port, causing the limiting ring 410 to move downward on the support plate 48, releasing the inner wrapping of the limiting ring 410 around the instrument body 2, making it easier to put on and take off the instrument body 2. By moving the push rod 44 downward, one end of the lever arm 49 slides inside the arc-shaped guide rod 414, and the spring 413 pushes the lever arm 49 and the bracket together, causing the other end of the lever arm 49 to rotate downward, fixing the pressure plate 47 to the top of the instrument body 2 to be tested, so that the instrument body 2 is fixed inside the limiting ring 410, facilitating the waterproof test of the instrument body 2.
