Description

Grenade and multi-function catapult

The invention relates to a throwing pipe, in particular to a throwing pipe capable of projecting grenade, baseball and lifesaving equipment.

According to the modern throwing device, it can be used for military or lifesaving. A gas pressure transmitter is installed in the throwing device, a projection device is placed in the throwing device and the trigger is buckled to make the gas The release produces a pressure that launches the projectile and falls on or around the object at a distance.

However, the pneumatic thrower is arranged to cooperate with the projection member so that the gas cannot be released before being fired, so that the thrower can only be used in combination with the use, such as a military thrower. Grenade or missile use, can not be used for life-saving appliances, if the thrower is used for life-saving only the use of floating objects, there is a disadvantage of a single use.

In addition, although a throwing device that springs out the projectile with a spring force is introduced on the market, the spring is first compressed after the projecting member is ejected, and then the elastic elastic returning force of the spring causes the projecting member to eject. If the spring is compressed for a long time and the elastic recovery is easy to cause elastic fatigue, the spring needs to be replaced to continue using the throwing device. Therefore, the throwing device needs to be completely disassembled before being replaced, and the caster structure is usually difficult to be designed. The solution takes a long time to replace the spring.

However, if the throwing device used for military purposes is to shoot a grenade, the insurance pin on the grenade must be removed and placed inside the throwing device to be ejected. The grenade on the grenade is removed, so that the grenade must be The ejection can not be temporarily changed to decide not to eject, and the hand grenade takes out the shortcomings of the thrower.

The inventor has a structure which is usually difficult to disassemble in view of the structure of the thrower, so that it takes a long time to replace the spring, and a single use method, such as the use of a military thrower, can only be used by a grenade or a missile, and cannot be used. In terms of lifesaving, the throwing device used for military purposes cannot temporarily change the decision not to eject, and the hand grenade takes out the throwing device and other shortcomings, which is the idea of creating and testing, and the sample test, and more After the revision was improved, I created this creation.

The present invention provides a grenade and a multi-function catapult, comprising: a throwing pipe, the throwing pipe is hollow through, the one end of the throwing pipe is filled with a launching port and the other end is provided with a spring blocking portion, and the filling emitting port is provided with a spring The projection member is thereby filled and ejected, and the projection tube is provided with a long rail and a through hole. When the projection member is provided with a safety pin, the through hole is projected to the hollow of the projection tube. And the user pulls the safety pin from the through hole, the projecting pipe is provided with a joint portion on an outer surface of one end of the spring stop; an ejection unit, the ejection unit comprises: a piston, a spring, and a spring a piston rod and a pull rod, the piston side is provided with a through hole, the piston is disposed at the hollow of the throwing tube, and the spring is disposed between the piston and the spring stop of the throwing tube, the end of the rod The other end of the device is provided with a fastening portion, the pull rod is disposed through the long rail, the through hole and the end of the device hole and is exposed outside the throwing tube; and a firing unit comprising: a group Seat, one button, two The connecting piece and the two springs have a receiving space therein, the bottom of the receiving space is provided with a consistent perforation and a set of joints at the end, the set of joints is a joint portion of the joint portion and the throwing pipe The button is provided with a groove extending from the inside to the outside.

However, as shown in the tenth figure, if the ejection spring 22 has been elastically fatigued and needs to be replaced, the two long rails 13, the through holes 215 and the device hole 231 are removed by the pull rod 24, and the piston 21 is rotated to fix the fixing buckles. The piece 40 is disengaged from the ejection spring 22, and the ejection unit 20 is taken out from the filling opening 11 to make the replacement of the parts easier and faster.

In addition, if the internal parts of the firing unit 30 are to be replaced, the joint portion 316 of the set of the bases 31 and the joint portion 16 of the throwing tube 10 are unlocked, and the internal parts of the firing unit 30 can be clearly seen and replaced. The lock member 317 and the positioning portion 314 can be unlocked, and the spring 34 can be directly removed from the positioning portion 314 for convenient maintenance and replacement.

Further, as shown in the eleventh and twelfth drawings, another embodiment of the grenade and the multi-function ejector according to the present invention is different from the above embodiment in that the other embodiment A positioning rail 18 is disposed in the hollow portion of the pipette 10, and a safety grip 52 is disposed on the projection member 50, and the positioning rail 18 is inserted into the positioning rail 18 by the safety grip 52 on the projection member 50 to make the projection. The safety pin 51 is directly aligned with the through hole 15 when the member 50 is positioned on the piston 21.

From the structure of the above specific embodiment, the following benefits can be obtained:

1. The piston rod 23 of the pure mechanical ejection unit 20 is fastened to the two fastening members 33 of the firing unit 30, and the piston 21 compresses the ejection spring 22, and the piston 21 is compressed by the high elastic force of the elastic spring 22 to return to the elastic state. The ejection of the projecting member 50 by the elastic force greatly increases the ejection distance of the projecting object 50, thereby achieving the diversification of use without the need to cooperate with the projectile 50 and for military use, practice or lifesaving.

2. If the ejection spring 22 has been elastically fatigued and needs to be replaced, the two long rails 13, the through holes 215 and the device hole 231 are removed by the pull rod 24, so that the ejection unit 20 is taken out from the filling and emitting opening 11 to achieve the replacement of the parts. Simple and fast.

3. The through hole 15 is used to remove the safety pin 51 of the projectile 50, and when the temporary determination is not to eject, the safety pin 51 can be reinstalled on the projectile 50 by the through hole 15, and the throwing pipe 10 is inverted. The projectile 50 slides out, and the projectile 50 that is explosive can be taken out from the throwing pipe 10 when it is temporarily not ejected.
