[0036] The first compression spring 18 is initially in a compressed state. The first compression spring 18 applies pressure to the movable block 43. Through the cooperation of the toothed plate 16, the gear 15 and the rotating shaft 11, the sealing cover plate 5 is tightly attached to the protective shell 3. When the protective shell 3 moves downward, the sealing cover plate 5 located above contacts the push block 33 located above the control panel 2. As the protective shell 3 continues to move downward, the push block 33 pushes the sealing cover plate 5 and the rotating shaft 11 to rotate relative to the fixed box 12, thereby changing the inclination angle of the sealing cover plate 5. The rotating shaft 11 is rotated by the gear. The wheel 15 drives the toothed plate 16 and the movable block 43 to move, and the length of the first compression spring 18 becomes shorter. When the sealing cover plate 5 is flipped to a preset position relative to the fixed box 12 and the protective shell 3, the iron plate 19 and the magnet block 21 are in contact, and the magnet block 21 applies a magnetic force to the iron plate 19 to fix the sealing cover plate 5 relative to the protective shell 3. As the protective shell 3 continues to move downward, the slider 7 contacts the top of the limit plate 10, and the upper half of the control panel 2 can be exposed, so that the staff can perform The protective shell 3 is operated.

The iron plate 19 is no longer in contact with the magnet block 21. The magnetic force between the magnet block 21 and the iron plate 19 is less than the preset value. The first compression spring 18 pushes the movable block 43 and the tooth plate 16 to move in the opposite direction, so that the sealing cover plate 5 can rotate in the opposite direction. The sealing cover plate 5 contacts the protective shell 3 again. The protective shell 3 and the two sealing cover plates 5 seal and protect the control panel 2. The protective shell 3 and the sealing cover plate 5 are reset to the initial position relative to the tester cabinet 1. When the protective shell 3 moves up, similarly, the lower half of the control panel 2 can be exposed, the top of the slider 7 and the top inner wall of the slide groove 6 are abutted, and the staff can operate the lower half of the control panel 2. The design of the first handle 22 is convenient for the staff to drive the protective shell 3 to move in the vertical direction.

[0038] The second compression spring 25 is initially in a compressed state. The second compression spring 25 applies pressure to the damping block 23 so that the damping block 23 and the inner wall of the slide groove 6 are tightly attached. The guide bar 8 and the guide groove 9 are designed so that the slider 7 can move smoothly in the vertical direction relative to the slide groove 6. The initial position of the plug block 27 is located in a slot 28 in the middle. The design of the slot 28 and the plug block 27 can prevent the protective shell 3 from shaking in the vertical direction relative to the side plate 4. When the protective shell 3 needs to be driven to move in the vertical direction relative to the tester cabinet 1, the staff drives the movable plate 26 to move through the second handle 32 so that the plug block 27 When the protective shell 3 is moved to the highest or lowest position, the plug block 27 moves to one side of the corresponding slot 28, and the third compression spring 31 drives the movable plate 26 to move so that the plug block 27 is inserted into the corresponding slot 28, so that the protective shell 3 is moved to the preset position and then fixed relative to the tester cabinet 1.

The inner wall is tightly attached. When the protective shell 3 needs to be temporarily still during the movement, the second compression spring 25 applies pressure to the damping block 23, which can still make the slider 7 and the damping block 23 temporarily still and fixed relative to the slide groove 6 and the side plate 4; when the slider 7 needs to slide out of the slide groove 6 to complete the removal of the protective shell 3, the staff drives the second fixing plate 36 and the positioning column 35 to move upward relative to the fixing plate 34 and the side plate 4, and the tension spring 37 is in a stretched state, so that the bottom end of the positioning column 35 is disengaged from the positioning hole 38, thereby releasing the lock on the position of the limit plate 10, and the staff drives the limit plate 10 to move horizontally to make the limit plate 10 move horizontally. The plate 10 is no longer located directly below the slider 7, and the slider 7 can slide out of the slide groove 6, and the tester cabinet 1 is supported by the base 39. When the tester cabinet 1 needs to be driven to move to the preset position, the length of the hydraulic telescopic rod 40 is reduced, and the length between the base 39 and the tester cabinet 1 can be reduced. The tester cabinet 1 drives the roller 41 to move downward, and the roller 41 passes through the avoidance hole 42. Finally, the roller 41 contacts the ground, and the base 39 no longer contacts the ground. The tester cabinet 1 is supported by the roller 41, and the staff can drive the tester cabinet 1 to move to the preset position through the roller 41.

[0039] A method for evaluating the durability of an enameled wire in this embodiment uses the enameled wire durability evaluation testing device as described above, and includes the following steps:

[0040] Step 1: When the control panel 2 is not needed, the control panel 2 is protected and sealed by the protective shell 3 and two sealing cover plates 5;

[0041] Step 2: According to the use area of ​​the control panel 2, the staff drives the protective shell 3 to slide vertically relative to the tester cabinet 1 through the damping sliding component, and the flipping structure drives a corresponding sealing cover plate 5 to flip, so that the control panel 2 is exposed from the protective shell 3, and the staff can operate the control panel 2;

[0042] Step 3: When the protective shell 3 needs to be removed from the tester cabinet 1, the locking unit is used to release the locking of the position of the limit plate 10;

[0043] Step 4: The staff drives the limit plate 10 to move horizontally so that the limit plate 10 is no longer directly below the slider 7. The staff drives the protective shell 3 and the slider 7 downward so that the slider 7 slides out of the slide groove 6, and the removal of the protective shell 3 and the slider 7 is completed.

[0044] Working principle: when the control panel 2 is not needed, the control panel 2 is protected and sealed by the protective shell 3 and the two sealing cover plates 5. According to the use area of ​​the control panel 2, the staff drives the protective shell 3 to slide vertically relative to the tester cabinet 1 through the damping sliding component, and the flipping structure drives a corresponding sealing cover plate 5 to flip, so as to avoid the sealing cover plate 5 from interfering with the control panel 2 and ensure that the control panel 2 is exposed from the protective shell 3. The staff can operate the control panel 2. When the protective shell 3 needs to be removed from the tester cabinet 1, the locking unit releases the lock on the position of the limit plate 10, and the staff drives the limit plate 10 to move horizontally so that the limit plate 10 is no longer directly under the slider 7. The staff drives the protective shell 3 and the slider 7 to move downward so that the slider 7 slides out of the slide groove 6, and the removal of the protective shell 3 and the slider 7 is completed. When the control panel 2 is not needed, the control panel 2 can be protected and sealed by the protective shell 3 and the sealing cover plate 5 to avoid dust falling on the control panel 2 and prevent the staff from accidentally touching the control panel, thereby ensuring the normal operation of the tester cabinet 1.

[0045] The first compression spring 18 is initially in a compressed state. The first compression spring 18 applies pressure to the movable block 43. Through the cooperation of the toothed plate 16, the gear 15 and the rotating shaft 11, the sealing cover plate 5 is tightly attached to the protective shell 3. When the protective shell 3 moves downward, the sealing cover plate 5 located above contacts the push block 33 located above the control panel 2. As the protective shell 3 continues to move downward, the push block 33 pushes the sealing cover plate 5 and the rotating shaft 11 to rotate relative to the fixed box 12, thereby changing the inclination angle of the sealing cover plate 5. The rotating shaft 11 is rotated by the gear. The wheel 15 drives the toothed plate 16 and the movable block 43 to move, and the length of the first compression spring 18 becomes shorter. When the sealing cover plate 5 is flipped to a preset position relative to the fixed box 12 and the protective shell 3, the iron plate 19 and the magnet block 21 are in contact, and the magnet block 21 applies a magnetic force to the iron plate 19 to fix the sealing cover plate 5 relative to the protective shell 3. As the protective shell 3 continues to move downward, the slider 7 contacts the top of the limit plate 10, and the upper half of the control panel 2 can be exposed, so that the staff can perform The protective shell 3 is operated. When the protective shell 3 moves up and the fixed column 13 on the sealing cover plate 5 contacts the corresponding correction block 14, as the protective shell 3 continues to move up, the fixed column 13 slides on the inclined surface of the correction block 14, and the correction block 14 pushes the fixed column 13 and the sealing cover plate 5 to rotate in the opposite direction. The iron plate 19 is no longer in contact with the magnet block 21. The magnetic force between the magnet block 21 and the iron plate 19 is less than the preset value. The first compression spring 18 pushes the movable block 43 and the tooth plate 16 to move in the opposite direction, so that the sealing cover plate 5 can rotate in the opposite direction. The sealing cover plate 5 contacts the protective shell 3 again. The protective shell 3 and the two sealing cover plates 5 seal and protect the control panel 2. The protective shell 3 and the sealing cover plate 5 are reset to the initial position relative to the tester cabinet 1. When the protective shell 3 moves up, similarly, the lower half of the control panel 2 can be exposed, the top of the slider 7 and the top inner wall of the slide groove 6 are in contact, and the staff can operate the lower half of the control panel 2. The design of the first handle 22 is convenient for the staff to drive the protective shell 3 to move in the vertical direction.

[0046] The second compression spring 25 is initially in a compressed state. The second compression spring 25 applies pressure to the damping block 23 to make the damping block 23 and the inner wall of the slide groove 6 close to each other. The guide bar 8 and the guide groove 9 are designed to make the slider 7 move smoothly in the vertical direction relative to the slide groove 6. The initial position of the plug 27 is located in a slot 28 in the middle. The design of the slot 28 and the plug 27 prevents the protective shell 3 from shaking in the vertical direction relative to the side plate 4. When the protective shell 3 needs to be driven to move vertically relative to the tester cabinet 1, the staff drives the movable plate 26 to move through the second handle 32 to disengage the plug 27 from the corresponding slot 28, and the movable plate 26 slides relative to the second guide column 29. The third compression spring 31 In the compressed state, when the staff drives the protective shell 3, the slider 7 and the movable plate 26 to move in the vertical direction, the plug block 27 and the outer wall of the side plate 4 slide in contact. When the protective shell 3 moves to the highest or lowest position, the plug block 27 moves to one side of the corresponding slot 28, and the third compression spring 31 drives the movable plate 26 to move so that the plug block 27 is inserted into the corresponding slot 28, so that the protective shell 3 is moved to the preset position and then fixed relative to the tester cabinet 1. Since the damping block 23 is in close contact with the inner wall of the slide groove 6, when the protective shell 3 needs to be temporarily stationary during the movement, the second compression spring 25 applies pressure to the damping block 23, which can still make the slider 7 and the damping block 23 temporarily stationary and fixed relative to the slide groove 6 and the side plate 4;

[0047] When the slider 7 needs to slide out of the slide groove 6 and the protective shell 3 is removed, the staff drives the second fixed plate 36 and the positioning column 35 to move upward relative to the fixed plate 34 and the side plate 4. The tension spring 37 is in a stretched state to make the bottom end of the positioning column 35 disengage from the positioning hole 38 and release the lock on the position of the limit plate 10. The staff drives the limit plate 10 to move horizontally so that the limit plate 10 is no longer located directly under the slider 7. The slider 7 can slide out of the slide groove 6 and support the tester cabinet 1 through the base 39. When it is necessary to drive the tester cabinet 1 to move to the preset position, the length of the hydraulic telescopic rod 40 is reduced to reduce the length between the base 39 and the tester cabinet 1. The tester cabinet 1 drives the roller 41 to move downward, and the roller 41 passes through the avoidance hole 42.
