Wherein, described lever is form flexible formula structure by sleeve pipe, and its length is locked by lock(ing) bolt.In described operating head, the inside length of mouth shape and width are set to 50mm and 25mm; The length of operating head concave shape structure both sides is 30mm.
The utility model compared with prior art, has the following advantages or beneficial effect:
(1) what can meet all types of low-voltage circuit breaker stops power transmission operation.Multipurpose low-voltage circuit breaker operation tool combines together organic for all types of low-voltage circuit breaker operating head, efficiently easy and simple to handle.
(2) low-voltage circuit breaker that can meet all kinds of small space stops power transmission operation.This instrument can between 0.5m-1m free adjustment locking, make it can in all kinds of environmental operations freely.
(3) security performance is high.The distance of operating personnel's distance low-voltage circuit breaker and charging equipment is extended to 0.5m-1m, eliminates fear and the psychological pressure of operating personnel, enhance processing safety and reliability, avoid because fear causes operating the potential safety hazard brought not in place.
(4) mechanical strength is high.Full alloy material guarantees that this instrument can bear the impulsive force of stopping power transmission operation and producing completely, guarantees that stopping power transmission operational motion reliably puts in place.
(5) quality is light, is convenient to one man operation.Aluminum alloy material also makes this instrument weight only have 500g, lightly practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of operating head in the utility model;
Fig. 3 is the left view of Fig. 2.
Embodiment
With reference to Fig. 1-Fig. 3, a kind of multipurpose low-voltage circuit breaker operation tool, comprise in a tubular form or the lever 1 of rod shape, one end of lever 1 is holding end 11, the other end of described lever 1 is provided with bindiny mechanism 2, and the side of bindiny mechanism 2 is fixed with operating head 4 by bolt 3; Described bindiny mechanism 2 is made up of the pipe that one end is flat, is provided with bolt hole 21 in the middle part of described flat end, and the side of flat end is provided with zigzag projection 22; Described operating head 4 is made into the structure at mouth shape 41 stacked character cut in bas-relief shape 42 by square steel, and a side end of character cut in bas-relief shape 42 structure is provided with hook 43, and the both sides of mouth shape 41 structure are provided with fixing hole 44, are provided with internal thread in fixing hole 44.Wherein, described lever 1 is form flexible formula structure by sleeve pipe, and its length is locked by lock(ing) bolt 12.In described operating head 4, the inside length of mouth shape 41 and width are set to 50mm and 25mm; The length of operating head 4 concave shape 42 structure both sides is 30mm.
Embodiment:
1, the making of lever 1: use for reference the extension type mop rod structure that market is sold, utilize the theory of mechanics of its free-extension locking, the aluminium-alloy pipe of two kinds of different inner diameters, thickness of pipe wall 2mm is adopted to be set with the lever 1 producing retractable, the extra heavy pipe end in its two pipe boxes dress portion is provided with the lock(ing) bolt 12 of latch functions, simultaneously, in one end of lever 1 for it installs insulating sleeve additional as holding end 11, length adjustment function and high mechanical properties can be met like this, its fail safe can be guaranteed again.
Lever 1 is alloy material, mechanical strength is high, telescopic framework can guarantee that action bars carries out adjustment locking between 0.5m-1m, the insulating sleeve installed additional is 10KV outdoor cable terminals cold shrink tube, can guarantee that action bars in operation is not breakdown, there is reliable insulation safety performance, meet the demands.
2, the fabrication and installation of bindiny mechanism 2: the connected mode and the fixed form that take into full account bindiny mechanism 2, bindiny mechanism 2 is knocked by one end and forms in flat pipe, be provided with bolt hole 21 in the middle part of described flat end for interspersed bolt 3, the side of flat end is provided with anti-slip for attended operation 4 of zigzag projection 22.By being inserted in the hole of bindiny mechanism 2 lower end on lever 1 top, and laterally punching penetrates bolt, locks with pad and nut, can meet reliable fixing and high mechanical properties like this, can guarantee that again it is quick detachable.
3, the making of operating head 4: at present, the low-voltage circuit breaker related in daily repairing is divided into breaker of plastic casing and bar shaped Fuse Type circuit breaker more, wherein, breaker of plastic casing operating handle is cuboid, in order to ensure operate reliable, put in place, therefore its operating head adopts rectangle "mouth" shape, simultaneously, because of the width of rated current its operating handle different and thickness also different, rated current to be 630A be at present breaker of plastic casing in maximum, therefore get slightly larger than its width and thickness, " mouth " word length and width are decided to be 50mm and 25mm.Bar shaped Fuse Type breaker operator handle is draw-ring type, and action of operating a switch needs a hook-type operating head, and feed motion needs " recessed " word shape fixed pull ring, guarantee operating process reliable, rapid, put in place.Final group member adopts 15mm thickness alloy, " mouth " word, " recessed " word and hooked head are carried out rational deployment, one-body molded, so both can meet all kinds of breaker operator, can guarantee again have enough mechanical strength reply switching impulses, meanwhile, the alloy of thickness like this and bindiny mechanism 2 to realize being flexible coupling of angle adjustable relatively easy.
4, the connection of operating head 4: operating head 4 is linked together with bindiny mechanism 2, and realizes the adjustable function of work angle.Bindiny mechanism 2 front end is as connector, and take protruding 22 positions of the zigzag of sawtooth mechanism to attach operating head 4, increasing friction force, prevents slippage; By the end of bolt 3 through being selected into after bolt hole 21 in fixing hole 44.Operating head 4 is fixed in bindiny mechanism 2 by bolt 3, as shown in Figure 1.Now, bolt 3, as " nut ", after operating head angle is determined, only need be tightened, operating head reliably can be connected with action bars by operating head 4.
The power transmission of stopping that the utility model can meet all types of low-voltage circuit breaker operates, efficiently easy and simple to handle; The low-voltage circuit breaker that can meet all kinds of small space stops power transmission operation; Security performance is high; Mechanical strength is high; Quality is light, is convenient to one man operation, convenient and practical.
