[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 9 The utility model provides a technical solution: a fuse-type disconnect switch with an anti-accidental touch function, comprising a base 1, a flip cover 2 rotatably mounted on the base 1, a fuse 10 mounted on the inner side of the flip cover 2, a contact 8 provided on the base 1, and an arc extinguishing chamber 6 mounted on one side of the contact 8. A handle 3 is integrally formed on the outer side of the flip cover 2, and the handle 3 facilitates the user to open or close the flip cover 2. A groove 13 is provided on the side of the base 1 close to the flip cover 2. The groove 13 is used to avoid a locking rod 93. A card slot 7 is provided on the inner wall of the groove 13. A locking mechanism 9 for fixing the flip cover 2 is provided inside the handle 3.

[0026] The locking mechanism 9 includes two cross bars 91 symmetrically slidably mounted in the handle 3, one end of the cross bar 91 is provided with a vertical bar 92, one end of the vertical bar 92 is provided with a locking rod 93, one side of the locking rod 93 is provided with a card block 99 that cooperates with the card slot 7, the card block 99 cooperates with the card slot 7 to fix the flip cover 2 and the base 1 to prevent people from accidentally opening the flip cover 2, and a button 98 is slidably mounted in the middle of the handle 3. The button 98 is set in the middle of the handle 3. When people hold the handle 3, they can press the button 98 conveniently without any problem. The invention does not require any extra operation and is very convenient to use. After pressing the button 98, the button 98 moves the protrusion 97, and the protrusion 97 squeezes the two cross bars 91 to move them away from each other. The cross bar 91 moves the locking rod 93 through the vertical rod 92, and the locking rod 93 drives the card block 99 to move. The card block 99 is disengaged from the card slot 7, thereby releasing the fixation of the flip cover 2 and the flip cover 2 can be opened. There are protrusions 97 on both sides of the button 98. The protrusions 97 can not only squeeze the cross bar 91 to make it move, but also prevent the button 98 from interfering with the handle 3. Separation occurs, a slant groove 911 is provided on the protrusion 97, and a second inclined surface 912 is provided on the end of the cross bar 91 close to the protrusion 97. The second inclined surface 912 is pressed against the slant groove 911. The second inclined surface 912 and the cross bar 91 make it easier for the protrusion 97 to squeeze the cross bar 91 to make it move. A cylinder 95 is provided on one side of the vertical rod 92. The cylinder 95 is used to limit the spring 94 to prevent the spring 94 from deflecting during the extension and contraction process. The outer side of the cylinder 95 is provided with a spring 94. The spring 94 is used to move to the vertical rod 92. The rod 92 applies a thrust so that when the flip cover 2 is closed, the block 99 can always be stuck in the slot 7, and the block 99 can also be automatically stuck in the slot 7 when the flip cover 2 is closed. The inner wall of the handle 3 is fixedly connected with a support block 910, and the support block 910 is used to fix the limit sleeve 96 in the handle 3. One side of the support block 910 is fixedly connected to the limit sleeve 96. The limit sleeve 96 is used to limit the cross bar 91 to prevent the cross bar 91 from deviating when it moves. The cross bar 91 is slidably connected to the limit sleeve 96.

[0027] Among them, a first inclined surface 4 is provided on the side of the block 99 away from the locking rod 93. The first inclined surface 4 is set so that when the flip cover 2 is closed, the side wall of the groove 13 will squeeze the first inclined surface 4 to move the block 99, thereby preventing the flip cover 2 from being blocked by the block 99 and unable to be closed, resulting in the need to press the button 98 when closing, thereby improving the convenience of use.

[0028] Among them, a through hole 12 is provided on the locking rod 93, and a stop rod 11 is fixedly connected to the inner side of the flip cover 2. The stop rod 11 is used to limit the stop rod 11 to prevent the stop rod 11 from deforming, causing the block 99 to be unable to align with the slot 7. The locking rod 93 is slidably connected to the stop rod 11 through the through hole 12.

[0029] Among them, an unlocking mark 5 is provided on the outer side of the button 98, and the unlocking mark 5 makes it easier for users to understand the function of the button 98.

[0030] The vertical rod 92 is slidably connected to the handle 3 .

[0031] When the flip cover 2 is fully closed, the block 99 is aligned with the card slot 7, and the spring 94 rebounds and resets, so that the block 99 is stuck in the card slot 7 to fix the flip cover 2, preventing people from accidentally opening the flip cover 2.
