Abstract
The invention discloses a sealing cylinder base-type fuse handle, which comprises a plastic handle and two eccentric sliding groove connection rods, wherein each eccentric sliding groove connection rod is made of sheet metal; each eccentric sliding groove connection rod comprises a mounting end and a fixing end; the fixing ends of the two eccentric sliding groove connection rods are fixed at the left end and the right end of the plastic handle in a one-to-one correspondence mode; the mounting end of each eccentric sliding groove connection rod is provided with an eccentric sliding groove; the eccentric sliding groove comprises a straight groove guiding section and a bent guiding section sequentially from outside to inside; the straight groove guiding section has a length of 20mm; each eccentric sliding groove connection rod is provided with a rotating shaft mounting hole; and each eccentric sliding groove connection rod is provided with an anti-rotating limiting groove. The sealing cylinder base-type fuse handle is in line with the human body engineering design, the bent strength is high, and an ejection accident to the handle can be prevented.
Description
technical field [0001] The invention relates to a handle of a sealed cylinder base type fuse. Background technique [0002] At present, American box-type transformers are widely used in wind power generation systems because of their compact structure and low price. American box-type transformers mainly use sealed cylinder base fuses. The fuse includes a sealing cylinder base, a fuse carrier and a fuse assembly. The sealing cylinder base is a cylindrical structure with one-way opening. The fuse carrier and fuse components are sequentially arranged in the sealing cylinder base from the opening direction of the sealing cylinder base. , The fuse-carrying parts include a bracket and a handle, but the handle in the prior art does not have a limit function, and it is easy to pop out of the hand when rotating, causing accidental injury to the operator. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art, and provide ...
