[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a refrigerator evaporator assembly and testing device, including a water tank 1, a top frame 101 fixedly connected to the top of the water tank 1, vertical grooves 102 on both the left and right sides of the top frame 101, a rotating component 2 inside the two vertical grooves 102, a placement component 3 for placing multiple evaporators at the outer end of the rotating component 2, a clamping component 4 for fixing multiple evaporators inside the placement component 3, and a testing component 5 for testing the airtightness of multiple evaporators at the top of the placement component 3. Through the coordinated arrangement of the water tank 1, rotating component 2, placement component 3, clamping component 4 and testing component 5, this device can conveniently assemble, fix and test the airtightness of multiple refrigerator evaporators at the same time during the use of the refrigerator evaporator assembly and testing device, thereby improving the testing efficiency of refrigerator evaporators.

[0021] As one implementation method in this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rotating assembly 2 includes a motor 201, which is fixedly mounted on the top of the top frame 101. A screw 202 is installed at the output end of the motor 201, and the screw 202 passes through one of the vertical slots 102. The bottom end of the screw 202 is rotatably positioned at the bottom end of the vertical slot 102. A guide rod 203 is fixedly connected between the top and bottom ends of the other vertical slot 102. The placement assembly 3 includes two sleeves 301, and a placement frame 302 is fixedly connected between the side ends of the two sleeves 301. One sleeve 301 is threaded to the outer end of the screw 202, and the other sleeve 301 is fitted onto the outer end of the guide rod 203. A top plate 305 is fixedly connected to the top side end of the placement frame 302, and several spaced partitions are fixedly connected to the bottom end of the placement frame 302. The bottom of the plate 303 and the placement rack 302 are provided with several slots 304. The side of the placement rack 302 is provided with a straight groove 306. The other side of the placement rack 302 away from the straight groove 306 is provided with a sliding groove 307. In practice, each evaporator is placed in the placement rack 302 and separated by each partition plate 303, so that the pipe opening of each evaporator is aligned with each sealing gas pipe 503. By starting the motor 201 to drive the screw 202 to rotate, the guide rod 203 limits the sleeve plate 301, so that the two sleeve plates 301 can be moved down. The movement of the sleeve plates 301 moves the placement rack 302 down into the water tank 1, so that the evaporator is submerged in the water. This facilitates the simultaneous detection of the pipe opening airtightness of multiple evaporators with the detection component 5.

[0022] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the clamping assembly 4 includes a bidirectional threaded rod 401, which is rotatably disposed between the inner side ends of the straight groove 306. The side end of the bidirectional threaded rod 401 extends to the outer side end of the placement rack 302. A knob 402 is fixedly connected to the side end of the bidirectional threaded rod 401. Two threaded sleeves 403 are threadedly connected to the outer end of the bidirectional threaded rod 401. A clamping plate 404 is fixedly connected to the side end of each threaded sleeve 403. A slider 405 is fixedly connected to the side end of each clamping plate 404. Each slider 405 is slidably connected in the slide groove 307. In practice, rotating the knob 402 drives the bidirectional threaded rod 401 to rotate. At this time, since the slider 405 is limited to slide in the slide groove 307, the two threaded sleeves 403 can drive the two clamping plates 404 to move closer to each other and clamp and fix each evaporator in the placement groove at the same time, so that the pipe opening of each evaporator is aligned with the bottom end of each sealing gas pipe 503.

[0023] As one implementation method in this embodiment, such as Figure 3As shown, the detection component 5 includes a cylinder 501, which is fixedly installed at the bottom of the top plate 305. A connecting plate 502 is installed at the telescopic end of the cylinder 501, and several sealing gas pipes 503 are installed at the bottom of the connecting plate 502. In practice, by starting the cylinder 501, the connecting plate 502 and each sealing gas pipe 503 are moved downwards, and each sealing gas pipe 503 is inserted into the pipe opening of each evaporator to seal and block it. By starting the motor 201, the screw 202 is rotated, which, in conjunction with the guide rod 203, limits the movement of the sleeve plate 301, allowing the two sleeve plates 301 to move downwards. 01 moves downwards, causing the placement rack 302 to move into the water tank 1, so that the entire evaporator is submerged in the water. At this time, several external air pumps blow air into each sealed air pipe 503. If the shape of the pipe opening of the evaporator is not standard, air leakage will occur. At this time, bubbles will be generated on the water surface near the leaking evaporator, thus realizing the airtightness test of multiple evaporators. Therefore, in the process of using the refrigerator evaporator assembly and testing device, this device facilitates the simultaneous assembly, fixing and airtightness testing of multiple refrigerator evaporators, thereby improving the testing efficiency of refrigerator evaporators.

[0024] Working principle: Each evaporator is placed in the rack 302, separated by a partition plate 303, aligning the inlet of each evaporator with the sealing gas pipe 503. Rotating the knob 402 drives the bidirectional threaded rod 401 to rotate. Because the slider 405 slides within the groove 307, the two threaded sleeves 403 move the two clamping plates 404 closer together, simultaneously clamping and fixing each evaporator in the rack, ensuring the inlet of each evaporator is aligned with the bottom end of each sealing gas pipe 503. Then, the starting cylinder 501 moves the connecting plate 502 and each sealing gas pipe 503 downwards, inserting each sealing gas pipe 503 into the inlet of each evaporator to seal and block it. Motor 201 drives screw 202 to rotate, cooperating with guide rod 203 to limit the position of sleeve plate 301, allowing the two sleeve plates 301 to move downwards. The downward movement of sleeve plates 301 causes placement rack 302 to move downwards into water tank 1, causing the evaporator to be completely submerged in water. At this time, several external air pumps blow air into each sealed air pipe 503. If the shape of the pipe opening of the evaporator is not standardized, air leakage will occur. At this time, bubbles will be generated on the water surface near the leaking evaporator, thereby realizing the airtightness test of multiple evaporators. Therefore, in the process of using the refrigerator evaporator assembly and testing device, this device facilitates the simultaneous assembly, fixing, and pipe opening airtightness test of multiple refrigerator evaporators, thereby improving the testing efficiency of refrigerator evaporators.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
