[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0045] The test tooling 100 for which this application claims protection is used to test the service life of a test sample 200. Here, the test sample 200 can specifically be a defrost heating tube of a refrigerator, an electric heating tube of a water dispenser, or other water-related heating elements.

[0046] As Figures 1 to 3 shown, the test tooling 100 provided by an embodiment of this application includes a water tank 10, a bench 20, a power supply assembly 30, a drive assembly 40, and a refrigeration assembly. The water tank 10 is used to hold a test liquid; the bench 20 is installed in the water tank 10 in a liftable manner, and the bench 20 is used to carry the test sample 200; the power supply assembly 30 is used to be electrically connected to the test sample 200 on the bench 20 and is used to control the power-on / off of the test sample 200; the drive assembly 40 is installed in the water tank 10 and is in transmission connection with the bench 20, and the drive assembly 40 can drive the bench 20 to make a lifting motion relative to the water tank 10 to switch the state between the test sample 200 on the bench 20 and the test liquid; the refrigeration assembly is used to cool the test liquid in the water tank 10 to control the temperature of the test liquid. Here, the test liquid is specifically water. The switching of the state between the test sample 200 on the bench 20 and the test liquid specifically refers to the switching between the state when the test sample 200 is immersed in the test liquid and the state when the test sample 200 is taken out of the test liquid. It should be noted that the power supply assembly 30 and the drive assembly 40 of this application are installed in the frame 110 above the water tank 10 in the vertical direction.

[0047] As can be seen from the above, when the test fixture 100 of the present application is used to test the test sample 200, the power supply component 30 can be used to supply power to the test sample 200 when it is removed from the test liquid, so that the test sample 200 is powered on and dry-burned. When the power supply component 30 stops supplying power to the test sample 200, the drive component 40 starts to drive the test sample 200 on the stand 20 to be immersed in the test liquid, so as to achieve the immersion of the test sample 200 when the power is off, and to achieve the test of the service life of the test sample 200. In this process, the refrigeration component can be used to cool the test liquid in the water tank 10, so that not only the recycling of the test liquid can be achieved, but also the temperature of the test liquid can be timely reduced to the temperature required for testing the test sample 200, which has the effect of improving test efficiency and reducing test costs. Here, the duration of the power supply component 30 controlling the power on and off of the test sample 200 can be specifically set according to the use requirements of the test sample 200, which will not be elaborated here.

[0048] like Figure 3 As shown, the stand 20 includes a support plate 21 and a hook 22, the hook 22 is mounted on the support plate 21, and the hook 22 is used to carry the test sample 200. In other words, the stand 20 can use the hook 22 to carry the test sample 200, which can facilitate the disassembly and assembly of the test sample 200 on the stand 20. Here, the hook 22 is configured as a metal hook, and the hook 22 can be assembled to the support plate 21 in a snap-fit ​​manner.

[0049] As preferably, Figure 2 As shown, the number of hooks 22 is configured to be multiple, and two hooks 22 in the multiple hooks 22 cooperate with each other and are used together to carry the test sample 200, specifically to carry the test sample 200 in a hanging manner, which can improve the stability of the test sample 200 when assembled on the stand 20. It should be noted that the number of hooks 22 on each support plate 21 can be configured to be 2, 4, or even a greater number of even numbers.

[0050] like Figure 2 As shown, the number of the racks 20 and the number of the drive assemblies 40 are both set to multiple, and the multiple racks 20 correspond to the multiple drive assemblies 40 one by one, and the racks 20 can be connected to the corresponding drive assemblies 40 by transmission; so that the test fixture 100 can test multiple test samples 200 at a time, which has the effect of further improving the test efficiency of the test fixture 100 when testing the test samples 200. Here, the multiple racks 20 are arranged in sequence along the length direction of the water tank 10. Here, the number of the racks 20 and the drive assemblies 40 are both 4, wherein each rack 20 can carry 5 test samples 200 at the same time.

[0051] like Figure 3As shown, the power supply component 30 includes a quick-plug connector 31, which is used to plug and match with the matching connector 210 on the test sample 200, and to electrically connect the quick-plug connector 31 to the test sample 200; in this way, the structural characteristics of the quick-plug connector 31 can be used to facilitate the disassembly and assembly between the power supply component 30 and the test sample 200. Here, when the quick-plug connector 31 is plugged and matched with the matching connector 210, the quick-plug connector 31 and the matching connector 210 are assembled and sealed, so as to play a waterproof role. It should be noted that the test sample 200 can be sealed with high-temperature resistant rubber, so that when the test sample 200 is plugged and matched with the quick-plug connector 31 of the power supply component 30 through the matching connector 210, the test sample 200 is in a closed state as a whole, so that when the test sample 200 is immersed in the test liquid, there will be no abnormalities such as water seepage and leakage. It should be noted that the power supply component 30 of the present application also includes a wire trough 32 and a wire row 33, which are arranged above the test liquid in the water tank 10, wherein the wire trough 32 is used to arrange the incoming wires for supplying power to the test samples, and the wire row 33 is used to supply power to each test sample 200 individually.

[0052] like Figure 3 As shown, the drive assembly 40 is configured as a telescopic cylinder 41, and the telescopic cylinder 41 is used to control the corresponding lifting and lowering of the platform 20. Of course, in other embodiments, the drive assembly 40 can also use a motor to drive the support plate 21 of the platform 20 through a screw nut assembly, which will not be elaborated here.

[0053] like Figure 1 , Figure 5 As shown, the refrigeration component includes a circulating air cooling system 51, and the circulating air cooling system 51 can cool the test liquid by air cooling.

[0054] As preferably, Figure 5 As shown, the circulating air cooling system 51 includes a finned copper tube 511, a fan 512 and an electromagnetic pump 513. The finned copper tube 511 is connected and communicated with the water tank 10, and is powered by the electromagnetic pump 513 to control the circulation of the test liquid in the water tank 10 in the finned copper tube 511. During this process, the fan 512 can work to cool the test liquid flowing in the finned copper tube 511.

[0055] like Figure 1 , Figure 6 As shown, the refrigeration assembly further includes a compression refrigeration system 52, which can cool the test liquid by heat conduction.

[0056] As preferably, Figure 6As shown, the compression refrigeration system 52 includes an outdoor air conditioner 521 and a copper coil 522. Refrigerant circulates internally between the outdoor air conditioner 521 and the copper coil 522. The compressor in the outdoor air conditioner 521 compresses and refrigerates the refrigerant, enabling the relatively cold refrigerant flowing through the copper coil 522 to exchange heat with the test liquid in the water tank 10, thereby achieving the purpose of compression refrigeration and rapidly cooling the test liquid in the water tank 10. Here, the copper coil 522 can be arranged in the interlayers on the sides and bottom of the water tank 10.

[0057] It should be noted that when the test tooling 100 of the present application is working, the refrigeration component can specifically control the temperature of the test liquid in the water tank 10 between 20 degrees and 30 degrees. Specifically, when the temperature of the test liquid is not higher than 20 degrees, neither the circulating air cooling system 51 nor the compression refrigeration system 52 is turned on; when the temperature of the test liquid is higher than 20 degrees, the circulating air cooling system 51 is turned on; when the temperature of the test liquid exceeds 30 degrees, both the circulating air cooling system 51 and the compression refrigeration system 52 are turned on simultaneously, which can play a role in reducing energy consumption.

[0058] The test tooling 100 further includes a temperature sensor (not shown in the figure). The temperature sensor is installed in the water tank 10 and is used to detect the temperature of the test liquid in the water tank 10 and generate a feedback signal; moreover, the refrigeration component can cool the test liquid according to the feedback signal to control the temperature of the test liquid. That is to say, the refrigeration component can be opened and closed according to the feedback signal generated when the temperature sensor measures the temperature, so as to realize the automatic control of the temperature of the test liquid in the water tank 10. Here, the temperature sensor is set as an NTC thermistor.

[0059] As Figure 4 shown, the test tooling 100 further includes a liquid level sensor 101. The liquid level sensor 101 is installed in the water tank 10 and is used to detect the liquid level of the test liquid in the water tank 10, thereby enabling the monitoring of the liquid level height of the test liquid in the water tank 10 to remind the operator to replenish the test liquid in the water tank 10 in a timely manner. Here, a liquid inlet pipe 102 is connected and communicated with the water tank 10, and a solenoid valve 1021 is arranged on the liquid inlet pipe 102. When the test tooling 100 is working, the solenoid valve 1021 can be used to control the on / off of the liquid inlet pipe 102 and realize the control of injecting the test liquid into the water tank 10 through the liquid inlet pipe 102. It should be noted that an overflow port 11 is also opened on the water tank 10, and the test liquid in the water tank 10 can be discharged outward through the overflow port 11, which can prevent the test liquid in the water tank 10 from submerging the wire grooves 32 and wire rows 33 of the power supply component 30.

[0060] In addition, as Figure 4As shown, a drain valve 12 is provided on the water tank 10, and the test liquid in the water tank 10 can be discharged outward through the drain valve 12, which can meet the subsequent use requirements for cleaning impurities in the water tank 10. Here, the drain valve 12 is set as a manual stop valve.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0062] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as it is within the scope of the essential spirit of the present invention, appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present invention.
