[0030] A fuse quality testing bench, such as Figure 1 — Figure 6 As shown, it includes a test bench assembly 1, a cabinet door assembly 2, a temperature control mechanism 3 and a test assembly 4. The cabinet door assembly 2 is arranged on the outside of the test bench assembly 1, the temperature control mechanism 3 is installed on the test bench assembly 1, and the test assembly 4 is located inside the test bench assembly 1.

[0031] like Figure 2-5 As shown, in the present disclosure, the test bench assembly 1 includes a console body 11, a test cabinet 12, a control panel 13, a display screen 14, a baffle 15, a sliding limit groove 16 and a support platform 17, wherein the test cabinet 12 is fixedly connected to the top of the console body 11, the control panel 13 is fixedly connected to the outside of the console body 11, the display screen 14 is fixedly connected to the outside of the console body 11 and is located above the control panel 13, the baffle 15 is fixedly connected to the outside of the test cabinet 12, the sliding limit groove 16 is opened on the top surface of the test cabinet 12, and the support platform 17 is fixedly connected to the bottom of the console body 11.

[0032] Thus, the operator controls various test operations in the test cabinet 12 through the control panel 13 and observes the test results and data through the display screen 14 .

[0033] like Figure 3-4 As shown, in a preferred embodiment, the cabinet door assembly 2 includes a sliding door 21, a tooth plate 22, a mounting plate 23, a motor 24, a gear 25 and a transparent observation window 26, wherein the sliding door 21 and the test cabinet 12 are slidingly connected to and located on the outside of the test cabinet 12 through a sliding limit groove 16, the tooth plate 22 is fixedly connected above the sliding door 21, the mounting plate 23 is fixedly connected above the test cabinet 12, the motor 24 is fixedly connected to the outside of the mounting plate 23, the gear 25 is fixedly connected to the outside of the output end of the motor 24 and meshes with the tooth plate 22, and the transparent observation window 26 is fixedly connected to the outside of the sliding door 21.

[0034] Therefore, when the operator needs to operate the opening and closing of the cabinet door, the operator turns on the motor 24 to rotate, the rotation of the motor 24 drives the gear 25 to rotate, the rotation of the gear 25 drives the tooth plate 22 to move, the movement of the tooth plate 22 drives the sliding door 21 to slide on the sliding limit groove 16, thereby automatically completing the opening and closing of the door. During the test, the operator observes the internal situation of the test cabinet 12 in real time through the transparent observation window 26.

[0035] like Figure 4-5 As shown, in the present disclosure, the temperature control mechanism 3 includes an air suction fan 31, an air inlet 32, a connecting pipe 33, a purification box 34, a cold air fan 35, a first filter 36, a hot air fan 37, a second filter 38 and a thermometer 39, wherein the air suction fan 31 is fixedly connected to the top of the test cabinet 12 and both ends pass through the test cabinet 12, the air inlet 32 ​​is fixedly connected to the bottom of the air suction fan 31 and is connected to the air suction fan 31, the purification box 34 is fixedly arranged above the test cabinet 12, the connecting pipe 33 is fixedly connected between the air suction fan 31 and the purification box 34 and are connected to each other, the cold air fan 35 and the hot air fan 37 are respectively fixedly nested on both sides of the test cabinet 12 and both ends pass through the test cabinet 12, the first filter 36 is fixedly connected to the outside of the cold air fan 35, the second filter 38 is fixedly connected to the outside of the hot air fan 37, and the thermometer 39 is fixedly arranged inside the test cabinet 12.

When it is necessary to test the performance of the fuse under different temperature environments, the operator turns on the hot air blower 37 to adjust the temperature in the test cabinet 12, and uses the thermometer 39 to measure the temperature in the test cabinet 12 in real time. After the test is completed, the operator turns on the cold air blower 35 to quickly cool down and dissipate heat in the test cabinet 12.

[0037] like Figure 5-6 As shown, in a preferred embodiment, the test assembly 4 includes a test board 41, an insulating plate 42, a copper sheet 43, a fixed block 44, a sliding groove 45, an adjusting screw 46, a clamping plate 47 and a fuse body 48, wherein the test board 41 is fixedly connected to the inside of the test cabinet 12, the insulating plate 42 is fixedly connected to the outside of the test board 41, the copper sheet 43 is fixedly connected to the outside of the test board 41 and is located on the inside of the insulating plate 42, the fixed block 44 is fixedly connected to the outside of the test board 41, the sliding groove 45 is opened on the surface of the fixed block 44, one end of the adjusting screw 46 is rotatably connected to the inner wall of the fixed block 44 and the other end passes through the top of the fixed block 44, two clamping plates 47 are provided, the two clamping plates 47 are threadedly sleeved on the outside of the adjusting screw 46 and are located on the outside of the fixed block 44, and the fuse body 48 is located between the two clamping plates 47 and both ends are abutted against the copper sheet 43.

[0038] Therefore, when installing the fuse, the operator first places the two ends of the fuse in contact with the copper sheet 43, and then the operator rotates the adjusting screw 46. The rotation of the adjusting screw 46 drives the two clamping plates 47 to move toward each other until the two clamping plates 47 and the upper and lower sides of the fuse body 48 are stably clamped. At this time, the fixation of the fuse body 48 is completed and the next test operation is carried out. When the fuse body needs to be disassembled, the operator only needs to rotate the adjusting screw 46 in the opposite direction to drive the two clamping plates 47 to disengage the clamping of the fuse body 48.

[0039] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
