Abstract
An electromagnetic gun with a safety plug comprises a bore and the plug. Internal threads are arranged between the left end of the inner wall of the bore and each steel ball on the inner wall of the bore, the plug is made of plastics and comprises an arc cylinder, a first cylinder and a second cylinder which are sequentially fixedly connected, horizontal central axes of the arc cylinder, the first cylinder and the second cylinder are overlapped, the chord length of the arc cylinder is slightly larger than the inner diameter of the bore, the thickness of the arc cylinder is about 5 millimeters, three to four external threads matched with the internal threads are arranged on the first cylinder, the length of the first cylinder is slightly larger than that of the external threads, and the diameter of the second cylinder is slightly smaller than the minimum distance between the surfaces of an upper steel ball and a lower steel ball on the inner wall of the bore. The overall length of the first cylinder and the second cylinder meets the condition that the right end of the second cylinder can exactly jack the left end of a bullet to pass through the steel balls when the plug is screwed, so that the bullet is ensured to be placed at a correct launching position.
Description
Technical field
The invention belongs to the physical experiment apparatus field, relate to a kind of magnetic artillery with safety plug.
Background technology
Magnetic artillery is a kind of physical experiment apparatus; Its experimentation is following: shell is filled in from the left end of bore, pushed away the steel ball of bore madial wall, the energy storage switch of closed electromagnetic big gun to the shell left end with thin stick; Press the emission switch of magnetic artillery after a while again, shell just penetrates from the right output port of bore.If when shell was installed, the shell left end was not pushed over the steel ball of bore madial wall, during emission, shell will penetrate from the left port of bore, and is accidents caused.The magnetic artillery of band safety plug can be eliminated this type of potential safety hazard fully.
Summary of the invention
In order to solve the problem of existence, the purpose of this invention is to provide a kind of magnetic artillery with safety plug, guaranteed the safety of magnetic artillery in operating process.
The technical solution adopted for the present invention to solve the technical problems is: the magnetic artillery of band safety plug; Comprise bore and plug, the inwall of said bore is provided with internal thread between from the left end to the steel ball, and said plug is made of plastic; Form by circular-arc cylinder, first right cylinder and second right cylinder; Circular-arc cylinder, first right cylinder and second right cylinder are fixedly connected sequentially, its central shaft in the horizontal direction overlaps, and the chord length of circular-arc cylinder is a bit larger tham the internal diameter of bore, thickness is 5 millimeter, and first right cylinder is provided with the external thread adaptive with internal thread; Externally threaded number of threads is 3-4; The first cylindrical length is a bit larger tham externally threaded length on it, and the second cylindrical diameter is slightly less than the up and down minor increment between two steel ball surfaces of bore inwall, and first right cylinder and the second cylindrical length overall satisfy: when plug is screwed; The second cylindrical right-hand member can just push up steel ball to the left end of shell, has guaranteed that shell is in correct transmitting site.During use; Shell is pushed from the bore left port, insert plug bore and screw, the second cylindrical right-hand member can just push up steel ball to the left end of shell; The energy storage switch of closed electromagnetic big gun; Press the emission switch of magnetic artillery after a while again, shell just penetrates from the right output port of bore, has thoroughly eliminated shell and has penetrated and accidents caused hidden danger from the bore left end.
The invention has the beneficial effects as follows, simple and practical, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation:
As shown in Figure 1; The magnetic artillery of band safety plug of the present invention comprises bore 7 and plug 9, the inwall of said bore 7 from the left end to the steel ball 5 be provided with internal thread 3; Said plug 9 is made of plastic; Form by circular-arc cylinder 1, first right cylinder 2 and second right cylinder 8, circular-arc cylinder 1, first right cylinder 2 and second right cylinder 8 is fixedly connected sequentially, its central shaft in the horizontal direction overlaps, internal diameter, thickness that the chord length of circular-arc cylinder 1 is a bit larger tham bore 7 are 5 millimeter; First right cylinder 2 is provided with the external thread 10 adaptive with internal thread 3; The number of threads of external thread 10 is 3-4, and the length of first right cylinder 2 is a bit larger tham the length of external thread 10 it on, and the diameter of second right cylinder 8 is slightly less than about bore 7 inwalls minor increment between two steel ball 5 surfaces; The length overall of first right cylinder 2 and second right cylinder 8 satisfies: when plug 9 was screwed, the right-hand member of second right cylinder 8 can just push up steel ball 5 to the left end of shell 6.During use; Shell 6 is pushed from bore 7 left port, insert plug 9 bores 7 and screw, the right-hand member of second right cylinder 8 can just push up steel ball 5 to the left end of shell 6; The energy storage switch of closed electromagnetic big gun; Press the emission switch of magnetic artillery after a while again, shell just penetrates from the right output port of bore, has thoroughly eliminated shell 6 and has penetrated and accidents caused hidden danger from bore 7 left ends.
