DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The aluminum electrolytic capacitor cover in this embodiment includes a capacitor cover body 1, and positive and negative lead terminals 2 are respectively provided at the left and right ends of the upper surface of the capacitor cover body 1, a shell 3 is provided on the lower side of the capacitor cover body 1, and a sealing mechanism 4 for quickly sealing the shell 3 is provided on the lower surface of the capacitor cover body 1, and an adjustment mechanism 5 for adjusting the position of the sealing mechanism 4 is provided on the left and right sides of the capacitor cover body 1.

[0022] The size of the sealing sleeve 401 is matched with the size of the inner cavity of the shell 3 , the sealing sleeve 401 is a rubber sleeve, and the size of the capacitor cover body 1 is larger than the size of the inner cavity of the shell 3 .

[0023] See also Figure 2-3 In order to fix the capacitor cover body 1 and the housing 3, the sealing mechanism 4 in this embodiment includes a sealing sleeve 401 fixed to the lower surface of the capacitor cover body 1, and the sealing sleeve 401 is inserted into the inner cavity of the housing 3 so that the lower surface of the capacitor cover body 1 contacts the upper surface of the housing 3. The left and right sides of the housing 3 are fixed with a card plate 402, and the left and right sides of the housing 3 are provided with a fixing box 403. The inner top wall of the fixing box 403 is fixed with a telescopic rod 404, and the outer surface of the telescopic rod 404 is movably sleeved with a compression spring 405. The telescopic rod 4 04 is fixed with a movable plate 406 on the lower surface, and a guide rod 407 is fixed in the middle of the lower surface of the movable plate 406, so that the guide rod 407 moves downward, and the movement of the guide rod 407 can drive the movable plate 406 to move. The movement of the movable plate 406 makes the telescopic rod 404 fixed thereon extend, and at this time the compression spring 405 is stretched, and plug blocks 408 are fixed to the bottom of the opposite sides of the two guide rods 407. The movement of the guide rod 407 makes the plug block 408 move until the recessed part of the inner cavity of the plug block 408 is at the same height as the clamping plate 402.

[0024] Among them, the two ends of the compression spring 405 are respectively fixedly connected to the opposite side of the fixed box 403 and the movable plate 406, and the limiting strips are fixed on the opposite sides of the left and right side walls of the inner cavity of the fixed box 403, and the left and right ends of the movable plate 406 are respectively slidably connected to the inner cavities of the two limiting strips.

[0025] In this embodiment, a through hole is opened on the inner bottom wall of the fixed box 403, the inner diameter of the through hole is larger than the outer diameter of the guide rod 407, the cross-sectional shape of the plug block 408 is an inverted U shape, and the size of the clamping plate 402 is adapted to the size of the inner cavity of the plug block 408.

[0026] It should be noted that guide plates are fixed to both left and right ends of the front side of the movable plate 406 , and the front side of the guide plates penetrates the fixed box 403 and extends to the front side of the fixed box 403 .

[0027] See also Figure 4 In order to adjust the position of the sealing mechanism 4, the adjustment mechanism 5 in this embodiment includes an installation box 501 fixed on the left and right sides of the capacitor cover body 1, and a threaded rod 502 is rotatably connected to the inner cavity of the installation box 501 through a bearing between the opposite sides of the left and right side walls of the inner cavity of the installation box 501. The threaded rod 502 rotates, and the rotation of the threaded rod 502 causes the movable sleeve 503 threadedly connected to its surface to move to the right, and the outer surface of the threaded rod 502 is threadedly connected to the movable sleeve 503.

[0028] Among them, the opposite sides of the two threaded rods 502 pass through the installation box 501 and extend to the side away from the installation box 501 and are fixed with a handle, and a connecting rod is fixed to the lower surface of the movable sleeve 503, and the lower surface of the connecting rod passes through the installation box 501 and extends to the lower side of the installation box 501 and is fixed to the upper surface of the fixed box 403, and a sliding groove is provided on the inner top wall of the installation box 501, and a sliding block is fixed on the upper surface of the movable sleeve 503, and the sliding block performs horizontal linear motion in the inner cavity of the sliding groove.

[0029] It is understandable that the movement of the movable sleeve 503 can drive the fixed box 403 to move through the connecting rod, so that the fixed box 403 moves to the side close to the card plate 402 until the insert block 408 is inserted into the outer surface of the card plate 402 to complete the sealing.

[0030] The working principle of the above embodiment is:

[0031] When it is necessary to fix the capacitor cover body 1 on the shell 3, first insert the sealing sleeve 401 into the inner cavity of the shell 3 so that the lower surface of the capacitor cover body 1 contacts the upper surface of the shell 3, and then pull the guide plate downward. The movement of the guide plate causes the guide rod 407 to move downward. The movement of the guide rod 407 can drive the movable plate 406 to move. The movement of the movable plate 406 causes the extension of the telescopic rod 404 fixed thereon. At this time, the compression spring 405 is elongated, and the movement of the guide rod 407 causes the plug block 408 to move until the recessed part of the inner cavity of the plug block 408 is at the same height as the card plate 402. The handle can be rotated, and the rotation of the handle causes the threaded rod 502 to rotate. The rotation of the threaded rod 502 causes the movable sleeve 503 threadedly connected to its surface to move to the right. The movement of the movable sleeve 503 can drive the fixed box 403 to move through the connecting rod, thereby causing the fixed box 403 to move to the side close to the card plate 402 until the plug block 408 is inserted into the outer surface of the card plate 402, and the sealing is completed.
