Detailed description of the invention
Defer to technique scheme, see Fig. 1 and 2, Portable ejection device of the present utility model, comprise launching tube 1, bullet 2 is placed in launching tube 1, spring 13 is set below bullet 2, described catapult-launching gear also comprise for Compress Spring 13 spring compression means and with spring compression means with the use of the spring fitting device for fixing spring 13 compression position.
Spring 13 below bullet 2 compresses under the effect in spring compression means, spring fitting device can the compression position of fixing spring 13, avoid, owing to slip out of the hand or misoperation causes bullet 2 inadvertent catapulting under spring force, causing the generation of fortuitous event.The utility model structure is simple, is easy to operation, is easy to carry, is suitable for field work.
Particularly, described spring compression means comprises the sliding panel 14 be arranged between described bullet 2 and spring 13, and be connected by going between sliding panel 14 with bullet 2, sliding panel 14 can slide along launching tube 1 inwall in described launching tube 1; Seizing wire 4 is installed in sliding panel 14 bottom surface, and seizing wire 4 one end is arranged on volume post 8 through described spring 13, and volume post 8 is arranged on transmission mechanism, and the rotation of transmission mechanism control volume post 8 makes seizing wire 4 can be wrapped on volume post 8.
Launching tube 1 inwall symmetric position is provided with chute, and sliding panel 14 can along slide; Described seizing wire 4 lower end, through launching tube 1 bottom surface, connects the volume post 8 be positioned at below launching tube 1.
Transmission mechanism rotates, and seizing wire 4 is wound around on volume post 8, pulls sliding panel 14 to move downward, thus Compress Spring 13, make spring 13 produce deformation; Transmission mechanism rotates backward, and seizing wire 4 unclamps by volume post 8, and sliding panel 14 moves upward under the effect of the elastic force of spring 13, thus is launched away by bullet 2.
Particularly, described transmission mechanism comprises turning cylinder 11, and described volume post 8 is coaxially installed on turning cylinder 11, and the end of turning cylinder 11 is installed with rocking handle 10; Described spring fitting device is arranged on turning cylinder 11.
Described rocking handle 10 drives turning cylinder 11 to rotate by spline structure, by shake rocking handle 10, turning cylinder 11 is rotated, and then drives the volume post 8 that it is arranged to rotate, and reaches the object being wound around seizing wire 4.
Particularly, described spring fitting device comprises the ratchet 9 be coaxially installed on described turning cylinder 11, and the side of ratchet 9 is provided with trigger 5, a detent contact of trigger 5 and ratchet 9; Trigger 5 is provided with return spring 7.
While the rotation of turning cylinder 11 rotation drive volume post 8 also Compress Spring 13, ratchet 9 is driven to rotate counterclockwise, in the process, due to the effect of trigger 5 and return spring 7, ratchet 9 can be stoped to rotate clockwise, thus avoid slipping out of the hand or misoperation time, the unexpected injection of bullet 2 causes unexpected injury.When needs launch bullet 2, only need to pull trigger 5, make it depart from ratchet 9, turning cylinder 11 reverses, thus reaches the object of being launched away by bullet 2.
Alternatively, described ratchet 9 and volume post 8 are all arranged on described turning cylinder 11 by flat key 19.
Further, between described ratchet 9 and volume post 8, be provided with the first sleeve 15, for the relative position between fixed ratchet wheel 9 and volume post 8.
Further, described Portable ejection device also comprises bracing frame 6, and the two ends of described turning cylinder 11 are arranged on bracing frame 6 respectively by the first rolling bearing 17 and the second rolling bearing 18; One end of described return spring 7 is installed on bracing frame 6; Described trigger 5 is hinged with bracing frame 6, and trigger 5 can rotate around pin joint under external force.The second sleeve 18 is provided with, for the relative position between fixing volume post 8 and bracing frame 6 between described volume post 8 and bracing frame 6.The end sleeve of described turning cylinder 11 is equipped with circlip 16, for limiting the axially-movable of turning cylinder 11.
Alternatively, described first rolling bearing 17 and be the interference fits of basic hole system between the second rolling bearing 20 and turning cylinder 11.
