The connection ground connection fitting 4 of insulator foot 3 is crossed, the side of the insulator foot 3 offers cavity 5, is equipped with ejection machine in the cavity 5
Structure 6, which, which is used as marked effect, can do rapidly bid in insulator body 2 after insulator, which is struck by lightning, to be worn
Show, be easy to find, specific: referring to Fig. 2-3, the ejection mechanism 6 includes air bag 61, ejection plate 62, ejection portion 63 and bullet
Penetrate bar 64；The ejection plate 62 with ejection portion 63 is affixed is integral, and two free ends in ejection plate 62 and ejection portion 63 point
It is not connected in the two opposite side walls of the cavity, and the entirety that the ejection plate 62 and ejection portion 63 form is put down with cavity bottom wall
Row, the air bag 61 is located in the space that cavity bottom wall, side wall, ejection plate 62 and ejection portion 63 form, in the air bag 61
Gas filled with certain volume, under normal circumstances, the variable quantity of gas internal energy is little in air bag, and volume expansion is small.The bullet
It penetrates the free end of plate 62 and the side wall of the cavity is that higher pair is connect, specifically may be provided so that the end of the ejection plate 62
Equipped with ball 621,621 part of ball leaks outside in the end of the ejection plate 62, and can 360 ° of rollings in ejection plate 62.
To which ejection plate 62 and side wall are point contact, frictional force very little of the ejection plate 62 in slide over side walls, it is only necessary to which lesser power is just
Ejection plate 62 can be pushed to move along cavity sidewalls.
Towards the side wall setting on the outside of insulator foot, the ejection portion 63 is interior to be equipped with piston ejector ram, ejector piston in the ejection portion 63
64, for one end elastic connection of the piston ejector ram, ejector piston 64 in ejection portion 63, other end part is resisted against cavity after stretching out ejection portion 63
Side-walls, 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 portion, the height of 65 relative datum of through-hole is greater than the height of 63 relative datum of ejection portion.
The piston ejector ram, ejector piston 64 can be ejected from ejection portion 63, to make mark in insulator body 2, specifically
As follows: the inner hollow in the ejection portion 63, ejection portion 63 is interior to be equipped with connected unit 100, which can be in ejection portion 63
Sliding, the both ends of the connected unit 100 are connected separately with the first elastic body 110 and the second elastic body 120, the piston ejector ram, ejector piston 64
It is 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 63, 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 63, thus when piston ejector ram, ejector piston 64 stretch out ejection portion 63 after, can be moved along elastic force direction,
After multiple piston ejector ram, ejector pistons 64 stretch out ejection portion 63, multiple piston ejector ram, ejector piston 64 is moved each along elastic force direction, thus in ejection portion
Umbrella is formed outside 63, it should be noted that piston ejector ram, ejector piston itself is also affected by gravity, and therefore, piston ejector ram, ejector piston selects quality as far as possible
Lighter material 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.
Embodiment 2
In order to further decrease piston ejector ram, ejector piston in the frictional force of slide over side walls, under the premise of comprising above content, piston ejector ram, ejector piston with
Side wall is set as spherical against the end at place, so that piston ejector ram, ejector piston is also that higher pair is connect with side wall.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited to this.So if the common skill of this field
Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
