[0024] As Figures 1-3 It is a schematic structural view of a fuse for a high-voltage fuse in a preferred embodiment of the present utility model. In this embodiment, a fuse for a high-voltage fuse includes a fuse tube body 1. Installation components 2 are provided at both ends of the fuse tube body 1. The installation components 2 include a fixed seat 21, clamping elastic pieces 22, and fixed rods 23. Clamping elastic pieces 22 are fixedly connected upward at both ends of the top surface of the fixed seat 21. Arc-shaped openings 24 are symmetrically formed in the inner walls of the two clamping elastic pieces 22, and the fuse tube body 1 is movably connected through the arc-shaped openings 24, thereby realizing the fixation of the fuse tube body 1. Fixed rods 23 are fixedly connected upward at the left and right ends of the fixed seat 21, and the outer wall surface of the fixed rods 23 is connected to the top of the clamping elastic pieces 22.

[0025] In this embodiment, connection holes 29 are formed at both end faces of the fixed seat 21.

[0026] In this embodiment, connection heads 26 are symmetrically and fixedly connected below the fixed rods 23, and locking blocks 27 are threadedly connected to the surfaces of the connection heads 26. The locking blocks 27 are movable within the fixed seat 21, and the fixed rods 23 and the connection heads 26 are designed with an integrally formed structure, thereby increasing the connection between the fixed rod 27 and the connection head 26.

[0027] In this embodiment, the connection heads 26 pass through the connection holes 29 to be threadedly connected to the locking blocks 27, thereby locking the fixed rods 23 after they are inserted into the clamping openings 25, effectively preventing the fuse from falling off due to loosening during use.

[0028] In this embodiment, clamping openings 25 are formed on the outer wall of the top of the clamping elastic pieces 22, and the inner wall of the clamping openings 25 is in contact with the outer wall of the fixed rods 23. With this structural design, through the cooperation of the clamping openings 25 and the fixed rods 23, the connection between the fuse tube body 1 and the clamping elastic pieces 22 is made simpler and more convenient.

[0029] In this embodiment, installation holes 28 are formed on the bottom surface of the fixed seat 21. With this structural design, it has the function of installing and fixing the fixed seat 21.

[0030] In this embodiment, the two ends of the fuse tube body 1 are sleeved with metal protective sleeves 11, and the outer wall of the metal protective sleeve 11 is in contact with the inner wall surface of the arc opening 24. This structural design is provided because the fuse tube body 1 is relatively fragile, and the metal protective sleeve 11 is provided to prevent the outer wall of the fuse tube body 1 from being damaged by the clamping force of the clamping spring 22.

[0031] In the present embodiment, the clamping spring piece 22 and the fixing seat 21 are designed with an integrally formed structure, which increases the connection strength between the clamping spring piece 22 and the fixing seat 21 and facilitates subsequent long-term use.

[0032] How it works

[0033] When using the fuse tube 1, first, the locking block 27 is loosened counterclockwise to allow the fixing rod 23 to be detached from the clamping opening 25, and then the clamping springs 22 are bent outwards to facilitate the removal of the fuse tube 1; when installing the fuse tube 1, the clamping springs 22 are bent outwards to place the fuse tube 1 at a position relative to the arc opening 24, and the clamping springs 22 are loosened to restore the clamping springs 22 to their original state, and then the fixing rod 23 is placed in the clamping opening 25, and the locking block 27 is rotated clockwise to lock the fixing rod 23 in the clamping opening 25. Thus, the installation of the fuse tube 1 is completed.

[0034] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
