First 208, limit angle 209 and fuse fixing device 210, one end axle of swing arm 207 are connected in lower bottom base 204, and other end axle connects
In fuse take-up device, the fuse take-up device includes locking spring plate 211 and back-moving spring 212, the locking spring plate 211 1
End is provided with cable clamping interface 213 and turned up, and other end cocker is stayed the limit angle 209 on base 204；
As shown in Fig. 4,6,7, operation ring 214, the fuse 202 and fuse take-up device are additionally provided with the upper bed-plate 203
One end of 210 connections is provided with buckle 215.
As shown in Fig. 4,6, in the present embodiment, the fuse fixing device 210 includes square washer 216 and square spacing
Groove 217, the square washer 216 can be arranged in stopper slot 217 by screw and bolt 218, moved down when on square washer 216
When dynamic, due to the limitation of square stopper slot 217, square washer 216 can not rotate, and the angle rotated in other words is very small, will not
Big to fuse generation pulls effect.
As shown in Fig. 3,5,6, the lower static contact 13 is double hook-shape structures, and the both sides of the swing arm 207 are each provided with
Ultimate range on one positioning convex point 218, two positioning convex points 218 is slightly less than the distance of double hook in lower static contact 13, with small 1-
4mm is advisable.
Embodiment 2
As shown in Figure 1, 2, 3, compared with Example 1, in the present embodiment, the upper static contact 12 is additionally provided with rain cover above
14, the side of the rain cover 14, the side of upper moving contact 205, the side of lower static contact 13, the side of lower moving contact 206 and

Embodiment 3
As shown in figure 8, a kind of operation instrument, for installing above-mentioned fuse switch, including lever 31 and operating head 32, institute
State and horizontal transverse arm 321 is set on operating head 32, be provided with anti-slip veins or antiskid groove on the transverse arm 321, transverse arm 321 can be inserted
Enter and be provided with cambered surface groove on the operation ring 214 on foregoing drop-type circuit breaker upper bed-plate 203, the end face of the operating head 32
322, the cambered surface groove 322 is engaged with the bulb 208 on lower bottom base 204, i.e., the cambered surface of cambered surface groove 322 can accommodate bulb
208 so that when fusion tube 2 is hung on the cambered surface groove 322 of operation instrument by bulb 208, even if between operation instrument and fusion tube 2
Produce very big angle change, fusion tube 2 is all without dropping.
The present invention operation principle be：
When installing, changing fuse, fuse is passed through to the body of fusion tube, one end connects upper moving contact, and the other end is at lower moving contact end
Stretch out, while push locking spring plate to body, the cable clamping interface for making the fuse of stretching body enter on locking spring plate, buckle is across card
Wire casing, locking spring plate tenses the fuse in body in the presence of buckle, and turning up on locking spring plate is partly played and prevent from melting
The effect that silk is skidded off out of cable clamping interface, the fuse of stretching is positioned under square washer, turns screw, make square washer by fuse again
Compress.By comparison, conventional mounting mode is twisted by way of circular gasket plus screw, and phase is played with locking spring plate in the present invention
The part of same-action is elasticity pressure tongue, and this is resulted in when turning screw, and fuse easily follows screw to rotate, and causes fuse more to draw more
Tightly, if fuse leaves a blank too small, fuse can be broken, if fuse leaves a blank excessive, fuse relaxation, influence safety, and fuse
How much turn is uncontrollable, cause fuse leave a blank can not accurate perception, have a strong impact on the reliability of power supply.It is of the invention then can protect
The fuse demonstrate,proved in fusion tube keeps tension, regardless of whether the fuse length outside body, when being compressed by screw, square washer is stuck in
In stopper slot, mode pad will not be rotated, and fuse will not rotate naturally, it is ensured that connection it is reliable.
When setting up or removing fusion tube, the bulb of fusion tube is placed in the arc groove of operation instrument, operation is hung over
On instrument, there can be very big angle between operation instrument and fusion tube in all directions.Conventional mounting instrument does not have arc
Also a cyclic structure is only inserted by transverse arm and moves up and down fusion tube without bulb with matching on connected in star, fusion tube,
There is the free degree only in a perpendicular, if operation instrument or fusion tube are slightly inclined, fusion tube is easy to fall off to fall down, influence peace
Dress.
When installing fusion tube in the case of light not strong or bad environments, because fusion tube installation site is high, installation personnel is only
With visually observing, it is difficult to ensure that being installed in place.The present invention has sticked reflector in corresponding place, if shone when installing with light source
Penetrate, then have very strong reflective, whether installation personnel is easy for seeing clearly and is installed in place.Meanwhile, swing arm both sides are provided with fixed
Position is raised, when fusion tube to be linked into the double hook of lower static contact, it is ensured that fusion tube hangs over the centre position of double hook, it is ensured that fusion tube is suitable
Profit is linked into double hook.
Embodiment of the present invention is only the description carried out to the preferred embodiment of the present invention, not to the present invention
Spirit and scope are defined, and on the premise of design philosophy of the present invention is not departed from, engineers and technicians are to this hair in this area
The all variations and modifications that bright technical scheme is made, all should fall into protection scope of the present invention, claimed skill of the invention
Art content, has all been recorded in detail in the claims.
