When a stop tank is provided and the telescopic inner tube is installed on the elastic outer tube, the barrel protection lid moves backward at the same time, and the adjustment device installed in the barrel protection lid is exposed to the outside. Gun lever inner tube that allows the user to adjust the trajectory when the bullet is fired with the adjustment switch On contraction structure.

  As shown in FIGS. 1 and 2, a conventional gun inner tube A is provided with a lever A1 installed on the gun inner tube A, and the lever A1 is fitted in a fitting tank A2 of the inner tube A. Further, a spring A3 that elastically expands and contracts is provided inside the inner tube A. The spring A3 corresponds to a seat A4 at the rear end of the barrel, and the inner tube A is moved backward by the lever A1. When pulled, the lever A1 can be fixed in the barrel slide tank A5. When the inner tube A is placed in the barrel storage tank A6, the inner tube A is fixed inside the rear end of the barrel.

However, since the inner tube A of the gun is installed in the space inside the gun at the time of installation, when the inner tube A of the gun is installed in a different gun, it is limited by the shape of the gun.
For this reason, how to eliminate the above-mentioned drawbacks is a technical problem to be solved by the present invention.

  The purpose of the present invention is to provide an inner tube structure that expands and contracts in a multistage manner, and can be combined with various gun shapes, saving the space inside the gun and making it difficult to limit the shape of the gun. It is to provide a telescopic structure.

  The present invention is mainly composed of a lever knob, an elastic outer tube, a telescopic inner tube, a protruding column body, a seat body, a barrel protection lid, a safety device, and an adjustment device. The lever knob is pierced through the barrel slide tank, and can be fixed in the fixed portion of the slide tank when the elastic outer tube is pulled backward, An elastic inner tube is provided in the elastic outer tube, and supports are provided on both sides of the elastic inner tube, and a spring for fixing the barrel protection cover is further installed on one of the supports, Further, a protruding column body and a seat are installed, a retaining tank corresponding to a hook portion provided in the safety device is provided in the barrel protection lid, and an adjustment device is further installed in the barrel protection lid, and the adjustment is performed. Features an adjustment switch for adjusting the trajectory on the device. That.

In order to show the inventiveness and practicality of the present invention more clearly, the following analysis will be made in comparison with the conventional product.
《Disadvantages of conventional products》

Second, it is necessary to occupy the internal space.
3. Easy to be limited by the shape of the gun.
4. Lack of inventive step and practicality.

<Advantages of the present invention>
1. It has an inner tube structure that expands and contracts in multiple stages.
Second, it can be combined with various gun shapes.
Thirdly, it can save space inside the gun.
5. It has inventive step and practicality.
6. Improve industrial competitiveness.

  Hereinafter, the present invention will be described in detail with reference to the drawings and embodiments. As shown in FIGS. 3, 4, and 5, the lever inner tube telescopic structure of the present invention includes an inner tube B having a lever knob C, an elastic outer tube D, an expandable inner tube E, a seat F, a barrel protection lid G, It comprises a safety device H and an adjustment device I.

  Among them, the lever knob C is installed in the fitting tank D1 of the elastic outer tube D by the fixing plug C1 and the spring C2, and this fitting tank D1 has a circular hole C3 for fixing the fixing plug C1 therein. ing.

  The lever knob C is pierced through the barrel slide tank C4, and when the elastic outer tube D is pulled backward, the lever knob C can be fixed in the fixing portion C5 of the slide tank C4.

  An elastic spring D2 is installed in the elastic outer tube D, and this spring D2 is further in contact with the expansion / contraction inner tube E, and supports E1 are provided on both sides of the expansion / contraction inner tube E. Further, a spring G1 for fixing the barrel protection lid G is installed.

  Further, a retractable spring E2 is installed in the telescopic inner tube E, and the spring E2 is in contact with the projecting column body F1 and the seat body F, and the elastic outer tube D, the telescopic inner tube E, the projecting column body F1, The seat body F forms an inner tube B that expands and contracts in a multistage manner.

  The barrel protection cover G is installed between the telescopic inner tube E and the seat F, and the barrel protection cover G includes a latching tank G2, which corresponds to the hook portion H1 of the safety device H. When the telescopic inner tube E is inserted into the elastic outer tube D, the barrel protection cover G is simultaneously moved backward, and the adjustment device I installed in the barrel protection lid G is exposed to the outside. The adjustment switch I1 on the device I allows the user to adjust the trajectory when the bullet is fired.

  The implementation method of the present invention is shown in FIGS. When using the present invention, when the lever knob C provided on the elastic outer tube D is pulled backward, the lever knob C moves inside the slide tank C4 on the barrel, and the lever connected to the elastic outer tube D The knob C can be simultaneously fixed in a fixing part C5 provided in the slide tank C4. When the lever knob C is fixed to the fixing part C5 of the slide tank C4, the inner expansion / contraction inner pipe E moves simultaneously. Entering the inside of the elastic outer tube D, the first-stage expansion / contraction operation in the above-described structure is completed.

  Further, when the elastic outer tube D and the expansion / contraction inner tube E complete this first-stage expansion / contraction operation, the spring E2 installed inside the expansion / contraction inner tube E simultaneously moves between the protruding column body F1 and the seat body F. The second-stage expansion / contraction operation is completed between the expansion / contraction inner tube E, the protruding column body F1 and the seat body F.

  When the spring E2 installed inside the telescopic inner tube E moves to the protruding column body F1 and the seat body F, the barrel protection lid G and the spring G1 installed inside the gun are simultaneously moved backward, and the barrel protection lid G The provided retaining tank G2 corresponds to the hook portion H1 provided in the safety device H, and when the above-mentioned telescopic inner tube E enters the inside of the elastic outer tube D, the barrel protection cover G is simultaneously moved backward, The adjusting device I installed in the protective lid G is exposed to the outside, and the user can adjust the trajectory when the bullet is fired with the adjusting switch I1 on the adjusting device I.

  The description given above is based on the best embodiment of the present invention, and does not limit the scope of the patent of the present invention.
