DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose and advantages of the present utility model clearer and more understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific requests of the present utility model.

[0020] As Figures 1-4 shown, a hermeticity testing device for a water tank plush toy includes a bottom plate 1 and a positioning mold 2. The positioning mold 2 is fixedly connected to the top end of the bottom plate 1. A positioning fixture 3 is arranged on one side of the top end of the bottom plate 1. The positioning mold 2 and the bottom end of the positioning fixture 3 are correspondingly arranged. A test end 4 for testing the hermeticity of the water tank of the plush toy is arranged at the bottom end of the positioning fixture 3. An air inlet pipe joint 41 is arranged on the side wall of the test end 4. A first slot 42 and a second slot 43 are arranged at the bottom end of the test end 4. An air flow channel 44 is arranged inside the test end 4. The first slot 42 is communicated with the air inlet pipe joint 41 through the air flow channel 44. An accommodation cavity 45 is arranged inside the test end 4. The bottom end of the accommodation cavity 45 is communicated with the bottom of the air flow channel 44. A plugging component 46 is slidably connected inside the accommodation cavity 45.

[0021] According to the above structure, when testing the hermeticity of the water tank of the plush toy, place the water tank inside the positioning mold 2, and then press down the test end 4 through the positioning fixture 3. When the test end 4 descends to press and position the water tank, the water inlet and outlet of the water tank are respectively inserted into the first slot 42 and the second slot 43. Connect the air outlet of an external air pump to the air inlet pipe joint 41 through a hose, and inflate the water inlet of the water tank through the air flow channel 44. After inflating a certain amount of gas, stop inflating, and then observe the pressure gauge on the air pump. If the pointer of the pressure gauge remains stable and does not move, it indicates that the hermeticity of the water tank is good; otherwise, it proves that the hermeticity of the water tank is poor. The positioning component of the water tank in this device is also the test component, which completes the connection operation of the test while positioning, with high test efficiency and strong practicability.

[0022] As Figure 4 shown, in order to facilitate the insertion of the water inlet and outlet of the water tank into the first slot 42 and the second slot 43, the bottom ends of both the first slot 42 and the second slot 43 are in the shape of a flared opening.

[0023] As Figure 4As shown, the plugging component 46 includes a plunger 461 and a circular ring 462. The plunger 461 is slidably connected to the inside of the placement cavity 45, and the circular ring 462 is slidably connected to the inside of the first slot 42. The bottom end of the plunger 461 is fixedly connected to a connecting rod 463. The bottom end of the side wall of the connecting rod 463 is fixedly connected to equally spaced connecting pieces 464. One end of the connecting piece 464 is fixedly connected to the inner wall of the circular ring 462. A groove is provided at the top end of the plunger 461, and a spring 466 is fixedly connected to the inside of the groove. The top end of the spring 466 is fixedly connected to the top end of the placement cavity 45. The bottom end of the plunger 461 is of a conical structure.

[0024] According to the above structure, during the test, as the test end 4 moves downward, the water inlet of the water tank is inserted into the inside of the first slot 42 and pushes the circular ring 462. The circular ring 462 pushes the connecting rod 463 and the plunger 461 and compresses the spring 466. At this time, the bottom end of the air flow channel 44 is opened, and the gas from the air pump can be filled into the inside of the water tank. When the test is completed, as the test end 4 rises, the water inlet of the water tank is separated from the first slot 42. At this time, under the elastic force of the spring 466, the plunger 461 moves downward to seal the bottom of the air flow channel 44, preventing dust from entering the inside of the air flow channel 44 from the bottom end of the air flow channel 44.

[0025] As Figure 4 shown, a circular rubber pad 431 is fixedly connected to the top end of the inner wall of the second slot 43, and an annular rubber pad 465 is fixedly connected to the bottom end of the circular ring 462.

[0026] According to the above structure, the circular rubber pad 431 and the annular rubber pad 465 play a sealing role. When the water inlet and the water outlet of the water tank are respectively inserted into the inside of the first slot 42 and the second slot 43, the circular rubber pad 431 and the annular rubber pad 465 can seal the top ends of the water outlet and the water inlet, preventing air leakage and improving the accuracy of the test.

[0027] The working principle of the present utility model is as follows: When testing the airtightness of the water tank of the plush toy, the water tank is placed inside the positioning mold 2, and then the test end 4 is pressed down by the positioning fixture 3. While the test end 4 descends to press and position the water tank, the water inlet and the water outlet of the water tank are respectively inserted into the inside of the first slot 42 and the second slot 43. The air outlet of the external air pump is communicated with the air inlet joint 41 through a hose, and air is inflated into the water inlet of the water tank through the air flow channel 44. After inflating a certain amount of gas, the inflation is stopped, and then the pressure gauge on the air pump is observed. If the pointer of the pressure gauge remains stable and does not move, it indicates that the airtightness of the water tank is good; otherwise, it proves that the airtightness of the water tank is poor. The positioning component of the water tank in this device is also the test component, which completes the connection operation of the test while positioning, with high test efficiency and strong practicability. During the test, as the test end 4 moves downward, the water inlet of the water tank is inserted into the inside of the first slot 42 and pushes the ring 462. The ring 462 pushes the connecting rod 463 and the plunger 461 and compresses the spring 466. At this time, the bottom end of the air flow channel 44 is opened, and the gas from the air pump can be inflated into the inside of the water tank. When the test is completed, as the test end 4 rises, the water inlet of the water tank is separated from the first slot 42. At this time, under the elastic force of the spring 466, the plunger 461 moves downward to seal the bottom of the air flow channel 44, preventing dust from entering the inside of the air flow channel 44 from the bottom end. The circular rubber pad 431 and the annular rubber pad 465 play a sealing role. When the water inlet and the water outlet of the water tank are respectively inserted into the inside of the first slot 42 and the second slot 43, the circular rubber pad 431 and the annular rubber pad 465 can seal the tops of the water outlet and the water inlet, preventing air leakage and improving the accuracy of the test.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special instructions and limitations.
