Specific embodiment
To keep the purposes, technical schemes and advantages of the utility model implementation clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.
As Figure 1-Figure 4, a kind of arc-chutes easy to install, including there are two the arc separating wall 1 being oppositely arranged and be set to every
Several arc extinguishing grid pieces 2 between arc wall 1, several arc extinguishing grid pieces 2 be parallel to each other and be spaced provided with two arc separating walls 1 it
Between, pass through between the arc separating wall 1 that top plate 3 is detachably connected and two are oppositely arranged at the top of two arc separating walls 1 being oppositely arranged and leads to
It is fixed to cross fixing piece 4, mounting hole 11 is respectively equipped on arc separating wall 1, the two sides of arc extinguishing grid pieces 2 are equipped with the peace in insertion mounting hole 11
Fill convex block 21.It is fixed due to connecting and passing through fixing piece 4 at the top of two arc separating walls 1 by top during above-mentioned side decides on a verdict, it sets in this way
It postpones, when installation, the installation convex block 21 of 2 two sides of arc extinguishing grid pieces need to be only inserted into the mounting hole 11 on arc separating wall 1, then general
Two arc separating walls 1 connect with top plate 3 and are fixed by fixing piece 4, and fixation will not fall off, and arc extinguishing grid pieces are installed
It is simple and quick, time cost can be saved in this way.
Two corresponding end tops of arc separating wall 1 are respectively equipped with slot 12, and the two sides of top plate 3 are equipped in insertion slot 12
Inserted block 31.After being arranged in this way, so that structure is more compact between arc separating wall 1 and top plate 3, top plate 3 be will not fall off.
The fixing piece 4 is plastic pin 41, and the top and bottom of arc separating wall 1 described in two are respectively equipped with mutual conduction
Via hole 42, the plastic pin 41 is inserted into via hole 42 two arc separating walls 1 are fixed.The plastic pin 41 includes
There are pin rod 43, pole cap 44 of the diameter greater than via hole 42 and the opening 45 set on 43 other end of pin rod on 43 one end of pin rod,
The pin rod for connecting 44 other end of pole cap is divided into upper pin rod and lower pin rod, the outer surface difference of upper pin rod and lower pin rod by the opening 45
Equipped with taper convex block 46.In above scheme, fixing piece 4 is plastic pin 41, and 41 front end of plastic pin is equipped with opening 45, and is equipped with cone
Shape convex block 46, in this way setting are so that the other end that pole cap 44 is arranged in pin rod 43 has elasticity, when installation, by upper pin rod and lower pin
Bar fitting, is inserted into via hole 42, then unclamps, and taper convex block 46 forms limit, completes consolidating for two arc separating walls 1 and top plate 3
