The purpose of protection circuit safe operation.
Existing tubular type fuse is Bullet structure, and after the fusible link in pipe fuses, which is reported
It is useless, it can not be recycled, result in waste of resources.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of fuses, can overcome existing skill
The above-mentioned deficiency of art.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of fuse, including cartridge fuse, the cartridge fuse is interior to be equipped with fusible link, and the both ends of the cartridge fuse are equal
It is connected with end cap, the end cap is equipped with filament mouth, and the lower part of the end cap is connected with lower fixed part and two fixing seats, described
The upper end of lower fixed part is equipped with the lower half circular hole cooperated with the fusible link, is connected with pin shaft between the fixing seat, described
Fixed part is rotatably connected on pin shaft, the lower end in fixed portion is equipped with the upper half circular hole cooperated with the fusible link.
Further, the lower end in fixed portion is connected with sector structure, and the upper half circular hole is located at the fan
In shape structure.
Further, the filament mouth is wedge structure, and sealing rubber ring is equipped at the filament mouth.
Further, the cartridge fuse is threadedly coupled with the end cap.
The utility model has the beneficial effects that the fusible link of the utility model only need to change fusible link after fusing can be again
It installs and uses, reduces the waste of resource, there is significant economic benefit.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of structural schematic diagram of fuse according to the utility model embodiment；
Fig. 2 is the cross-sectional view of the terminal cap moiety of the utility model；
In figure: 1, cartridge fuse；2, end cap；3, fusible link；4, fixing seat；5, upper fixed part；6, sector structure；7, wire vent
Mouthful；8, lower half circular hole；9, lower fixed part；10, pin shaft.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figs. 1-2, a kind of fuse according to the utility model embodiment, including cartridge fuse, the guarantor
Fusible link 3 is equipped in dangerous fiber tube 1, the both ends of the cartridge fuse 1 are respectively connected with end cap 2, and the end cap 2 is equipped with filament mouth 7,
The lower part of one of end cap 2 is connected with lower fixed part 9 and two fixing seats 4, the upper end of the lower fixed part 9 be equipped with it is described
The lower half circular hole 8 that fusible link 3 cooperates is connected with pin shaft 10 between the fixing seat 4, is rotatably connected on the pin shaft 10
Fixed part 5, the lower end in fixed portion 5 are equipped with the upper half circular hole cooperated with the fusible link 3.
In one embodiment, the lower end in fixed portion 5 is connected with sector structure 6, and the upper half circular hole is set
In the sector structure 6.
In one embodiment, the filament mouth 7 is wedge structure, and sealing rubber ring is equipped at the filament mouth 7.
In one embodiment, the cartridge fuse 1 is threadedly coupled with the end cap 2.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
According to a kind of fuse described in the utility model, including cartridge fuse, fusible link is equipped in the cartridge fuse 1
3, the both ends of the cartridge fuse 1 are respectively connected with end cap 2, and the end cap 2 is equipped with filament mouth.
Wherein, fixed part and fixing seat are fixedly connected in end cap, fixing seat is 2, and has one between 2 fixing seats
Fixed interval is connected with shaft between two fixing seats, in specific design, through-hole is equipped in two fixing seats, shaft is logical
It crosses the through-hole and fixing seat is rotatablely connected, be connected with fixed part in shaft, in specific design, open up confession on upper fixed part
The hole that shaft passes through, shaft, which passes through the hole, can be realized the rotation connection of fixed part and shaft, upper fixed part and lower fixed part
Upper to offer upper half circular hole and lower half circular hole respectively, it is solid up and down that upper half circular hole and the cooperation of lower half circular hole can be such that fusible link is fixed on
Determine between portion.
When specifically used, when fusible link fusing, end cap is removed, is being located at fusible link not by rotating upper fixed part
Between upper and lower fixed part, the fusible link damaged can be removed by then extracting fusible link out, and new fusible link is then passed through end
Filament mouth on cap coats sealant when necessary between end cap and fusible link.
In conclusion the fusible link of the utility model the utility model only needs to change fusible link after fusing to pacify again
Dress uses, and reduces the waste of resource, has significant economic benefit.
