Specific: referring to Fig. 2-3, the ejection mechanism 6 includes air bag 61, ejection plate 62, ejection guns 63 and piston ejector ram, ejector piston 64；The bullet
It penetrates plate 62 to be connected in the two opposite side walls of the cavity, and the ejection plate 62 is parallel with cavity bottom wall, the air bag 61 is located at
In the space that cavity bottom wall, side wall and ejection plate 62 form, the gas of certain volume, general feelings are filled in the air bag 61
Under condition, the variable quantity of gas internal energy is little in air bag, and volume expansion is small.The two opposite side walls of the ejection plate 62 and the cavity
For higher pair connection, it specifically may be provided so that the both ends of the ejection plate 62 are equipped with ball 621, outside 621 part of ball
It leaks in the both ends of the ejection plate 62, and can 360 ° of rollings in ejection plate 62.To which ejection plate 62 is that point connects with two sidewalls
Touching, frictional force very little of the ejection plate 62 in slide over side walls, it is only necessary to which lesser power just can push ejection plate 62 along cavity side
Wall is mobile.
The ejection guns 63 of inverted L-shaped is connected in the ejection plate 62, the ejection guns 63 includes horizontal ejection portion 632 and erects
Direct-connected socket part 631, the interconnecting piece 631 are vertically fixed in the ejection plate 62, and the ejection portion 632 deviates from insulator foot 3
The lateral wall of middle part setting, i.e. ejection portion 632 towards insulator foot 3 is arranged, and is equipped with piston ejector ram, ejector piston 64, institute in the ejection portion 632
One end elastic connection of piston ejector ram, ejector piston 64 is stated in ejection portion 632, the side of cavity is resisted against behind the stretching ejection portion 632 of other end part
At wall, by piston ejector ram, ejector piston 64 against side wall be equipped with through-hole 65, insulation elastic slice is equipped at the through-hole 65, with 3 bottom of insulator foot
On the basis of, the height of 65 relative datum of through-hole is greater than the height of 632 relative datum of ejection portion.
The piston ejector ram, ejector piston 64 can be ejected from ejection portion 632, to make mark in insulator body 2, be had
Body is as follows: the inner hollow in the ejection portion 632, connected unit 100 is equipped in ejection portion 632, which can be in ejection portion
Sliding in 632, the both ends of the connected unit 100 are connected separately with the first elastic body 110 and the second elastic body 120, the bullet
Bar 64 is penetrated to be connected by the second elastic body 120 with connected unit 100.
In some embodiments, the connected unit 100 is prism-frustum-shaped, the bottom surface connection first of the prism-frustum-shaped connected unit 100
Elastic body 110, and multiple sides are connected separately with multiple second elastic bodies 120, the second elastic body 120 described in each
It is connected with a piston ejector ram, ejector piston 64, second elastic body 120 and the end face of its two connecting pins are vertical, multiple described
After piston ejector ram, ejector piston 64 stretches out ejection portion 632, diverging forms umbrella outward.First elastic body 110 and the second elastic body 120
It is in compressive state, and the first elastic body 110 is used as elastomer-assisted, convenient for accelerating the quick pop-up of piston ejector ram, ejector piston 64.
In some embodiments, the connected unit 100 is quadrangular frustum pyramid shaped, the first elasticity of bottom surface connection of the connected unit 100
Ontology 110, four sides of the connected unit are separately connected there are four the second elastic body 120, the second elasticity sheet described in four
Body 120 is connected with four piston ejector ram, ejector pistons 64 respectively again, and two connecting end surfaces of the second elastic body 120 are connected unit 100 respectively
The end face of side and piston ejector ram, ejector piston 64, the two connecting end surfaces are parallel to each other, and vertical with the second elastic body 120, are arranged in this way
Purpose be: make piston ejector ram, ejector piston 64 by an inclined elastic force, which is decomposed into the horizontal force for being parallel to piston ejector ram, ejector piston 64
With the vertical force perpendicular to ejection portion 632, thus when piston ejector ram, ejector piston 64 stretch out ejection portion 632 after, can be transported along elastic force direction
Dynamic, after multiple piston ejector ram, ejector pistons 64 stretch out ejection portion 632, multiple piston ejector ram, ejector piston 64 is moved each along elastic force direction, thus in bullet
It penetrates and forms umbrella outside portion 632, it should be noted that piston ejector ram, ejector piston itself is also affected by gravity, and therefore, piston ejector ram, ejector piston selects as far as possible
The material of lighter weight is made into, in addition, the compression elasticity of the second elastic body is larger, to reduce the influence of piston ejector ram, ejector piston gravity.
When insulator is by being struck by lightning, the temperature rise of 3 moment of insulator foot sharply increase the interior of gas in air bag 61 can,
Gas expansion does work outward, thus, 61 volume of air bag increases, after pushing the mobile lesser one end distance of ejection plate 62, piston ejector ram, ejector piston
64 reach at the through-hole 65 on side wall, and under the effect of the elastic force of the first elastic body 110 and the second elastic body 120, moment is pushed away
Dynamic piston ejector ram, ejector piston 64 pops up from the elastic slice of through-hole 65, and multiple piston ejector ram, ejector pistons 64 diffuse to form umbrella-shaped structure in side-wall outer side, thus
The external of insulator forms obvious mark point, finds, accelerates the exclusion time of failure convenient for patrol officer, ensures route
Normal operation.
As previously mentioned, although the gravity of piston ejector ram, ejector piston can impact the forming shape of piston ejector ram, ejector piston, as long as piston ejector ram, ejector piston
It can extend out to outside insulator foot and play marked effect, in addition, the quantity of piston ejector ram, ejector piston is either one or more,
As long as the purpose of the present invention can be reached.
