Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of the utility model gun barrel position.
Fig. 3 is the utility model partial enlarged drawing in use.
Detailed description of the invention
Technical problem, technical scheme and the beneficial effect that will solve in order more to clearly demonstrate the utility model patent, below in conjunction with Figure of description and embodiment, be further elaborated to the utility model.
As illustrated in fig. 1 and 2, a kind of teaching javelin of the present utility model, javelin is robbed bar 3 by front end gun barrel 1 and rear end and is formed, gun barrel 1 is connected by screw thread 6 with chamber bar 3, the tubular structure that gun barrel 1 is hollow, gun barrel 1 front end is provided with the rifle head 4 that soft plastic is made, rifle head 4 is interior for being provided with cavity, cavity and gun barrel 1 connect, rifle head 4 is provided with some through holes 9, described barral of a gun 3 front ends and gun barrel 1 cooperation place are fixed with spring 5, spring 5 other ends are fixedly connected with sliding shoe 8, sliding shoe 8 can slide in gun barrel, barral of a gun 3 is provided with rubber sleeve 2, in use, the position of not only can mark holding, and in the time holding, be unlikely to skid.
In use, pack lime mark powder 10 into gun barrel inside, then sliding shoe 8 is filled in to gun barrel 1 is rear to be screwed barral of a gun 3 by screw thread, now sliding shoe 8, because spring 5 acts on, is suspended in gun barrel 1, leaves certain compression stroke with gun barrel 1 bottom.In the time throwing, mark powder 10 is sealed in gun barrel 1, in the time of rifle head 4 front end contact impact ground, due to the inertia of gravity and javelin colliding surface, sliding shoe 8 elongates spring along sliding to rifle head 4 in cylinder, because sealing ring 7 is installed on sliding shoe 8, make sliding shoe 8 move downward compressed air, at this moment, be contained in mark powder 10 in rifle head 4 and gun barrel 1 through hole 9 from rifle head and splash, in the time that rifle head lands, mark powder splashes and forms mark pick-up point on the ground, can measure the distance throwing a javelin, compared with existing javelin, its pick-up point is more easily measured, and rifle head of the present utility model position is soft plastic material, even careless accidental injury people in the middle of flight, can not cause large injury yet, greatly reduce again the danger in javelin teaching, being applicable to the javelin teaching of each school and match uses.
