Description
Technical field
The utility model is related to a kind of electric power tools, and in particular to a kind of instrument for being capable of quick-replaceable fuse.
Background technology
Fuse is also referred to as current insurance silk, has been mainly overload protective function.When electric current flows through conductor, because leading
Body is there are certain resistance, so conductor will generate heat, and caloric value follows this formula：Q=0.24I2RT；Wherein Q is
Caloric value, 0.24 is a constant, and I is the electric current for flowing through conductor, and R is the resistance of conductor, and T is the time that electric current flows through conductor；
Formula is not difficult to find out the simple operation principle of fuse according to this.A kind of fuse is true when the material and its shape that make fuse
Fixed, resistance R is just opposite to be determined (if temperature-coefficient of electrical resistance without considering it).When electric current flows through it, it will generate heat,
Its caloric value is also increasing as time increases.The size of electric current and resistance determines the speed for generating heat, fuse
It constructs the situation installed with it and the speed that heat dissipates is determined, if the speed for generating heat is less than the speed that heat dissipates,
Fuse will not fuse.If generate heat speed be equal to heat dissipate speed, considerable time in it
It will not fuse.If the speed for generating heat is more than the speed that heat dissipates, then the heat of generation will be more and more.And because
As soon as having constant specific heat and quality for it, the increase of heat is shown in the rise of temperature, when temperature is increased to the molten of fuse
Or more when fuse just fused.Here it is the operation principles of fuse.It should be understood that designing from this principle
The physical characteristic of selected materials must be studied in earnest, and ensure that they have consistent physical dimension when manufacturing fuse.Because this
Can a little factors work normally fuse effect of crucial importance.Equally, when it is used, have to correctly
It is installed.
And in power equipment maintaining, especially more in some regional thunderstorms, high-voltage insurance is often burned, due to high-voltage insurance
Generally all on 2 meters or more overhead, labor intensity is big, while fuse needs to be pressed into pipe, and a people can not complete to operate,
At least two people is needed to coordinate, when replacing, the collision with drainage thread is often caused, replaces extremely difficult.
Utility model content
Technical problem to be solved in the utility model is that existing high-voltage insurance replacing is inconvenient, drainage thread and fuse meeting
Collision is generated, and labor intensity is big, and its purpose is to provide a kind of instrument for being capable of quick-replaceable fuse, which passes through

Dynamic, both direction is wound simultaneously, while realizes two actions, reduces manpower.
Fixed gear is cased in shaft in one of shaft, and fixed gear is arranged on above gear-box, locking system can
The turned position of fixed gear is controlled.Fixed gear and one of driving cog are coaxial, are arranged at outside gear-box, convenient for lock
Locking apparatus insertion controls gear rotation process and position.
Locking system includes two pieces of support plates being mutually parallel, and support plate is vertically fixed on the top surface of gear-box, is propping up
Strip is provided between fagging, axis pin is provided on strip, both ends are connected simultaneously with support plate after axis pin passes through strip, and strip
It can rotate and be inserted into the tooth socket of fixed gear around the axis of axis pin, spring, bullet are provided between strip and gear-box
Spring is connected simultaneously with strip and gear-box, and support plate is arranged between spring and fixed gear.According to being needed when in use into line position
When putting with angle locking, strip is rotated, strip is inserted into the tooth socket of fixed gear and fixed gear is prevented to rotate, when unlocking,
Due to the elastic reaction of spring, the one end being connected with spring only need to be depressed, it is possible to strip is removed from tooth socket, for the ease of
Quickly realize this operating process, so strip is designed as L-type, using when rotate clockwise 90 ° of arrangements, and least significant end
As strip rotation is inserted into the tooth socket of fixed gear, the other end connection of spring and strip is realized to rotational angle
Control.
For the ease of the connection with other components, by not having in shaft, the part that the shaft for covering fixed gear is located at gear-box is horizontal
Section is square, and square toes shaft also allows for Reverse Turning Control and connection.
The utility model compared with prior art, has the following advantages and advantages：The instrument is by by rope set
It is rotated in shaft, rope and drainage thread is staggered, fuse is loaded into pipeline, realizes the quick of high-voltage fuse
It replaces, it is easy to operate, reduce labor intensity.
