Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a fuse structure of GCS type low pressure pull-out type cubical switchboard, including base 1, a pair of insulating seat 11 is installed through the bolt in base 1's top, install binding post 12 through the bolt on the insulating seat 11, install fuse 2 between two binding post 12, binding post 12's top has closely welded the card reed 121 that is the U-shaped form, the first and last both ends of fuse 2 overlap respectively in the inboard of two card reeds 121, make the both ends of fuse 2 overlap respectively on two card reeds 121, and make two binding post 12 pass through fuse 2 electric connection.

In this embodiment, the top end of the base 1 is further provided with a plugging device 3, and the plugging device 3 includes a fixed seat 31 fixed at the top end of the base 1 through a bolt, a movable plate 32 located above the fixed seat 31, and a cam 33 connected between the fixed seat 31 and the movable plate 32.

Specifically, a boss 311 is integrally formed at a front side edge of a top end of the fixed seat 31, a rotating shaft 3111 is inserted into the top end of the boss 311, and a tail end of the rotating shaft 3111 penetrates through a tail end of the cam 33 and is rotatably connected with the cam 33, so that the tail end of the cam 33 is hinged to the boss 311 through the rotating shaft 3111. A dial 331 is integrally formed on the inner surface of the head end of the cam 33, and when the dial 331 is dialed, the cam 33 is driven to rotate around the rotating shaft 3111, so as to drive the dial 331 to move.

Furthermore, vertical rods 312 are integrally formed at two corners of the rear side of the top end of the fixed seat 31, sliding grooves 313 are formed in the end faces of the inner sides of the vertical rods 312, the movable plate 32 is inserted between the two sliding grooves 313 and is in sliding connection with the sliding grooves 313, a waist-shaped groove 321 is formed in the outer surface of the bottom of the movable plate 32, the shifting shaft 331 extends into the waist-shaped groove 321, a top seat 322 is integrally formed at the top end of the movable plate 32, a pair of clamping seats 323 in a U-shaped structure is integrally formed at the rear end of the top seat 322, and the clamping seats 323 are clamped on the fuse 2. When the dial 331 moves along with the cam 33, the dial 331 pushes the inner wall of the waist-shaped groove 321 to enable the dial 331 to drive the movable plate 32 to move up and down along the sliding groove 313, when the dial 331 rotates gradually to the top, the movable plate 32 is gradually driven to the highest position by the dial 331, so that the holder 323 moves up and brings the fuse 2 away from the clamping spring pieces 121, and the purpose of detaching the fuse 2 is achieved, at this time, the old fuse 2 can be detached and then the new fuse 2 is placed in the two holders 323, then the cam 33 is continuously dialed to enable the dial 331 to rotate downward, the dial 331 drives the movable plate 32 to move downward, so that the holder 323 presses the mounted fuse 2 between the two clamping spring pieces 121, the installation work of the fuse 2 is completed, and the use is convenient and fast.

Further, a crank 332 is integrally formed on an outer side surface of the head end of the cam 33, and the cam 33 is conveniently driven to rotate by rocking the crank.
