Technical Field

[0001] This utility model relates to the field of home appliance safety inspection and testing technology, and in particular to a home appliance safety inspection and testing device. Background Technology

[0002] Household appliances mainly refer to various electrical and electronic appliances used in homes and similar places, also known as civil appliances or daily appliances. Before being sold, household appliances need to undergo safety testing to ensure their quality of use.

[0003] Patent publication number CN216622544U discloses a safety performance testing platform for household appliances, including a vertically arranged back plate and side plates. The side plates are located on both sides of the front of the back plate, facing each other. Both side plates can be moved along the width of the back plate to adjust the distance between them. The back plate and the two side plates enclose a testing space for placing the appliance. By using the back plate and side plates to create this testing space, and by adjusting the distance between the side plates according to the size and installation standards of the appliance, the platform can simulate the actual installation environment of the appliance, thereby improving the accuracy of subsequent performance testing.

[0004] The above devices simulate the installation environment for electrical appliances by setting up side panels. However, in actual safety testing, it is often necessary to conduct extreme performance tests on home appliances. Under such extreme test conditions, the temperature of home appliances often rises. The above devices lack the corresponding auxiliary heat detection function and have relatively simple functions. Therefore, a home appliance safety inspection and testing device is proposed to solve the above problems. Utility Model Content

A conveyor belt then transports the appliance to a temperature sensor for testing. During the testing process, the heat generated by the appliance's operation is transferred outwards. The temperature sensor is moved to contact the first telescopic heat-conducting plate, and by detecting the temperature of this plate, the operating temperature of the appliance can be determined. This information helps personnel assess the appliance's operating status and heat dissipation performance.

[0024] A home appliance safety inspection and testing device, through the design of the adjustment component, after rotating the bidirectional threaded rod, the first push-pull rod flips and pushes and pulls the top heat-conducting plate up and down, thereby increasing the height of the top heat-conducting plate. After rotating the threaded adjustment rod, the second push-pull rod flips and pushes the auxiliary plate, thereby adjusting the distance between the second telescopic heat-conducting plates on the left and right sides. Accordingly, when dealing with home appliances of different sizes, the position of the top heat-conducting plate and the second telescopic heat-conducting plate can be adjusted to ensure the accuracy of temperature detection.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 The present invention will be described in further detail below.

[0034] This utility model discloses a home appliance safety inspection and testing device. (Refer to...) Figures 1-7 It includes a main frame 1 and a conveyor belt 3. A transmission roller 2 is rotatably connected to the inside of the main frame 1. The transmission roller 2 is arranged at equal intervals inside the main frame 1. The conveyor belt 3 is located outside the transmission roller 2 and is in contact with the transmission roller 2. An auxiliary mechanism 4 is provided on the conveyor belt 3.

[0035] The auxiliary mechanism 4 includes mounting blocks 41, which are arranged at equal intervals on the outer side of the conveyor belt 3. The bottom of the mounting blocks 41 is integrally formed with mounting rods 42. The bottom of the mounting rods 42 is fixedly connected to a placement frame 43. The bottom of the inner cavity of the placement frame 43 is fixedly connected to a bottom heat-conducting plate 44. A top heat-conducting plate 45 is provided on the top of the bottom heat-conducting plate 44. A first telescopic heat-conducting plate 46 and a second telescopic heat-conducting plate 47 are respectively provided between the top heat-conducting plate 45 and the bottom heat-conducting plate 44. The two ends of the first telescopic heat-conducting plate 46 are fixedly connected to the top heat-conducting plate 45 and the bottom heat-conducting plate 44 respectively. The two ends of the second telescopic heat-conducting plate 47 are fixedly connected to sliders 48. The two sliders 48 are slidably connected to the top heat-conducting plate 45 and the bottom heat-conducting plate 44 respectively.

[0036] Two vertical plates 49 are fixedly connected to the bottom of the main frame 1, and a horizontal plate 491 is fixedly connected between the two vertical plates 49. A cylinder 492 is fixedly connected to the horizontal plate 491, and a rectangular plate 493 is fixedly connected to one end of the cylinder 492. A temperature sensor 494 is fixedly connected to the rectangular plate 493. A through groove 495 is opened on the rear side wall of the placement frame 43. When conducting safety inspection tests on home appliances, the home appliances can be placed in the frame space enclosed by the top heat-conducting plate 45, the bottom heat-conducting plate 44, the first telescopic heat-conducting plate 46, and the second telescopic heat-conducting plate 47 in the placement frame 43. The conveyor belt 3 transports the home appliances to the front of the temperature sensor 494 for testing. During the test, the heat generated by the home appliances during operation is transferred outward. The temperature sensor 494 is moved to fit against the first telescopic heat-conducting plate 46. By detecting the temperature of the first telescopic heat-conducting plate 46, the temperature status of the home appliances during operation can be determined, which helps the staff to judge its operating status and heat dissipation indicators.

[0037] A display screen 496 is fixedly connected to the front of the horizontal plate 491. The display screen 496 is electrically connected to the temperature sensor 494. The temperature detected by the temperature sensor 494 can be displayed on the display screen 496. An L-shaped plate 497 is fixedly connected to the bottom of the horizontal plate 491. A power socket 498 is fixedly connected to the L-shaped plate 497. The power socket 498 is used to power the detection equipment.

[0038] Auxiliary mechanism 4 includes an adjustment component, which includes a U-shaped plate 499. The U-shaped plate 499 is located at the bottom of the placement frame 43 and extends into the interior of the placement frame 43. Two auxiliary plates 481 are located inside the placement frame 43. A second telescopic heat-conducting plate 47 is fixedly connected to the two auxiliary plates 481 respectively. A support plate 482 is fixedly connected to the bottom of the placement frame 43. A threaded adjustment rod 483 is rotatably connected to the support plate 482. One end of the threaded adjustment rod 483 is rotatably connected to the bottom of the placement frame 43. A bidirectional threaded rod 484 is rotatably connected inside the placement frame 43 and extends out of the placement frame 43. Two control blocks 485 are slidably connected to the bottom wall of the placement frame 43. The bottom of each control block 485 is movably connected to a first push-pull rod 486 through a movable hinge. One end of the first push-pull rod 486 is movably connected to the top of the top heat-conducting plate 45 through a movable hinge. The threads at both ends of the bidirectional threaded rod 484 are in the same direction.

[0039] The bidirectional threaded rod 484 passes through the two control blocks 485 in sequence, and the bidirectional threaded rod 484 is connected to the two control blocks 485 by threads respectively. The threaded adjusting rod 483 passes through the bottom wall of the U-shaped plate 499 and is connected to the U-shaped plate 499 by threads. The inner sides of the U-shaped plate 499 are movably connected to the second push-pull rod 487 by movable hinges. One end of the second push-pull rod 487 is movably connected to one side of the auxiliary plate 481 by movable hinges. After the U-shaped plate 499 moves, it drives the second push-pull rod 487 to flip.

[0040] A mounting plate 5 is fixedly connected to the top of the main frame 1. A motor 6 is fixedly connected to the top of the mounting plate 5. A first gear 7 is fixedly connected to the motor 6 through the output shaft. A second gear 8 is fixedly connected to the outside of one of the transmission rollers 2. The first gear 7 is located on one side of the second gear 8 and meshes with the second gear 8. When the first gear 7 rotates, it drives the second gear 8 to rotate. A base plate 9 is provided at the bottom of the main frame 1. Two vertical plates 49 are fixedly connected to the top of the base plate 9. The base plate 9 provides bottom support.

[0041] In actual operation, the device is first connected to the power supply. When conducting safety inspection tests on home appliances, the home appliances can be placed in the frame space formed by the top heat-conducting plate 45, the bottom heat-conducting plate 44, the first telescopic heat-conducting plate 46, and the second telescopic heat-conducting plate 47 in the placement frame 43. After the motor 6 starts working, it drives the first gear 7 to rotate. The first gear 7 drives the second gear 8 to rotate. The second gear 8 drives the connected transmission roller 2 to rotate. This transmission roller 2 drives the external conveyor belt 3 to rotate. Through the above connection relationship, it can be seen that the placed home appliances can be conveyed in this way. When the corresponding placement frame 43 is conveyed to the front of the temperature sensor 494, it is detected.

[0042] During the testing process, the power socket 498 provides power for the testing. The heat generated by the equipment during operation is transferred to the top heat-conducting plate 45, the bottom heat-conducting plate 44, the first telescopic heat-conducting plate 46, and the second telescopic heat-conducting plate 47. These plates are interconnected; if one plate becomes too hot, the heat will be transferred to other plates. After the cylinder 492 operates, it moves the rectangular plate 493. The rectangular plate 493 then moves the temperature sensor 494 through the slot 495 into the placement frame 43, where it finally comes into contact with the first telescopic heat-conducting plate 46. By detecting the temperature on the first telescopic heat-conducting plate 46, the overall temperature status of the appliance during operation can be determined, further identifying any abnormalities in its operation.

[0043] To address the varying sizes of different household appliances during testing, a rotatable bidirectional threaded rod 484 drives two control blocks 485 to move towards or away from each other. The movement of the control blocks 485 causes the first push-pull rod 486 to flip, which in turn pushes and pulls the top heat-conducting plate 45 up and down, thus raising its height. Rotating the threaded adjusting rod 483 moves the U-shaped plate 499, which in turn flips the second push-pull rod 487. This flip pushes the auxiliary plate 481, which in turn moves the second telescopic heat-conducting plate 47, adjusting the distance between the left and right sides. This allows for adjustment of the positions of the top heat-conducting plate 45 and the second telescopic heat-conducting plate 47 when placing household appliances of different sizes, ensuring accurate temperature detection.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
