DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the utility model is a withstand voltage tester with a detachable dust cover, comprising a shell 1 and a withstand voltage tester 2 arranged in the shell 1, dust covers 3 are inserted on both sides of the shell 1, and the two dust covers 3 are symmetrically arranged, two card blocks 4 are fixedly installed on each dust cover 3, and each card block 4 is provided with a plurality of jacks 5, two card slots 6 are provided on both sides of the shell 1, and the card blocks 4 are inserted in the card slots 6 on the same side, installation grooves 7 are provided on both sides of the shell 1, and locking components for locking the dust covers 3 on the same side are provided in the installation grooves 7, and a groove 8 is provided at the bottom of the shell 1 and an adjustment component is provided in the groove 8.

[0030] The locking assembly includes a bidirectional screw rod 9 rotatably installed in the mounting groove 7, and the outer surfaces of the two sections of the thread of the bidirectional screw rod 9 are threadedly installed with a connecting plate 10, and a plurality of plug rods 11 are slidably installed in each slot 6, and the plug rods 11 are used in conjunction with the jack 5 on the same side, and the plurality of plug rods 11 on the same side are fixedly connected to the connecting plate 10 on the same side, and a gear 12 is fixedly installed on the bidirectional screw rod 9, and buttons 13 are slidably installed on both sides of the housing 1, and a rack 14 meshing with the gear 12 on the same side is fixedly installed on the button 13, and a first spring 15 is fixedly installed in the mounting groove 7, and the rack 14 is fixedly connected to the first spring 15 on the same side.

[0031] Pressing the button 13 compresses the first spring 15 and drives the rack 14 to move. The movement of the rack 14 drives the gear 12 and the bidirectional screw 9 to rotate. The rotation of the bidirectional screw 9 drives the connecting plates 10 on both sides to move away from each other and makes the insertion rod 11 move out of the insertion hole 5, thereby releasing the lock on the block 4. The second spring 18 drives the push plate 17 to reset under the action of its own elastic force, and pushes the block 4 out of the slot 6 through the push plate 17, so that the dust cover 3 can be removed from the shell 1. The dust cover 3 can be removed from the shell 1 without the help of tools, which is simple to operate and more convenient to use.

[0032] Among them, a first telescopic rod 16 is arranged in the first spring 15, and the two ends of the first telescopic rod 16 are respectively fixedly connected to the tooth block and the inner wall of the mounting groove 7 on the same side. The first telescopic rod 16 can guide and support the first spring 15 during the extension and contraction of the first spring 15, so as to avoid the first spring 15 from being offset and skewed, and ensure the stability of the first spring 15 during the extension and contraction process.

[0033] Among them, a push plate 17 is slidably installed in each slot 6, and a plurality of second springs 18 are fixedly installed between the push plate 17 and the inner wall of the slot 6 on the same side. During the installation of the dust cover 3, the push plate 17 is squeezed by the block 4 and compresses the second spring 18. When the block 4 is unlocked during the disassembly of the dust cover 3, the pressure on the push plate 17 disappears, and the second spring 18 drives the push plate 17 to reset and push the block 4 out of the slot 6 under the action of its own elastic force, so as to facilitate the quick disassembly of the dust cover 3.

[0034] Among them, a second telescopic rod 19 is arranged in each second spring 18, and the two ends of the second telescopic rod 19 are respectively fixedly connected to the push plate 17 and the inner wall of the card slot 6 on the same side. The second telescopic rod 19 can guide and support the second spring 18 during the extension and retraction of the second spring 18, thereby ensuring the stability of the second spring 18 during the extension and retraction process.

[0035] Among them, the adjustment component includes a rotating shaft 20 rotatably installed in the groove 8, one end of the rotating shaft 20 extends to the outside of the shell 1 and is fixedly installed with a knob, two threaded rods 21 are rotatably installed in the groove 8, a worm gear 22 is fixedly installed on the threaded rod 21, and a worm 23 meshing with the worm gear 22 is fixedly installed on the rotating shaft 20, a sleeve 24 is threadedly installed on the bottom end of the threaded rod 21, and a support block 25 is fixedly installed on the bottom end of the sleeve 24, and the threaded rod 21 rotates to drive the sleeve 24 and the support block 25 to move downward, and the downward movement of the support block 25 can prop up one end of the shell 1, so that the withstand voltage tester 2 is tilted and the tilt angle of the withstand voltage tester 2 can be adaptively adjusted according to the observation needs of the worker, so that the user can observe the readings of the withstand voltage tester 2.

[0036] The two sides of the support block 25 fit with the two sides of the inner wall of the groove 8, which can prevent the sleeve 24 from rotating while moving on the threaded rod 21, thereby ensuring the stability of the movement of the sleeve 24 and the support block 25.

[0037] During operation, the rotating shaft 20 is driven to rotate by turning the knob, and the rotating shaft 20 rotates through the worm 23 and the worm wheel 22 with the pulley threaded rod 21 to rotate. The rotation of the threaded rod 21 drives the sleeve 24 and the support block 25 to move downward. The downward movement of the support block 25 can prop up one end of the shell 1, so that the withstand voltage tester 2 is tilted and the tilt angle of the withstand voltage tester 2 can be adaptively adjusted according to the observation needs of the workers, so that the user can observe the readings of the withstand voltage tester 2. When installing the dust cover 3, press the button 13 to compress the first spring 15 and drive the rack 14 to move. The movement of the rack 14 drives the gear 12 and the bidirectional screw rod 9 to rotate. The rotation of the bidirectional screw rod 9 drives the connecting plates 10 on both sides to move away from each other and move the insertion rod 11 out of the slot 6, and then the block 4 is inserted into the corresponding slot 6 and the second spring 18 is compressed by the push plate 17, and then the button 13 is released. The external force on 15 disappears and the rack 14 is driven to reset under its own elastic action. During the resetting process, the rack 14 drives the two-way screw rod 9 to rotate and drive the connecting plates 10 on both sides to approach each other, and the plug rod 11 is inserted into the insertion hole 5 on the same side to lock and fix the card block 4, thereby completing the installation of the dust cover 3. When the dust cover 3 is disassembled and replaced, the button 13 is pressed to compress the first spring 15 and drive the rack 14 to move. The movement of the rack 14 drives the gear 12 and the two-way screw rod 9 to rotate. The two-way screw rod 9 rotates and drives the connecting plates 10 on both sides to move away from each other and make the plug rod 11 move out of the insertion hole 5, thereby releasing the lock of the card block 4. The second spring 18 drives the push plate 17 to reset under the action of its own elastic force, and pushes the card block 4 out of the card slot 6 through the push plate 17, so that the dust cover 3 can be removed from the housing 1. The installation and disassembly of the dust cover 3 can be achieved without the help of tools, which is simple to operate and more convenient to use.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
