Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a link belt for ammunition used for military automatic firearms.

(Prior Art and its Problems) It is well known that link belts are used for bullets in military automatic firearms. Therefore, when loading a bullet with the link belt, when the bullet is loaded, the bullet is pulled out from the link and loaded, and the single link that holds the bullet from the link belt is separated, and this link is placed near the rim of the cartridge case. The method of pushing down and loading is adopted, and the present invention belongs to the latter method.

It is needless to say that this type of link belt is required to reliably hold bullets, and the link belt is not easily separated except when necessary, and it is easy to separate when loading. , The link must be pushed down smoothly.

(Means for Solving Problems) The present invention provides a link belt for a firearm, which is formed by connecting a plurality of links for ammunition in a line, for the purpose of satisfying the above-mentioned requirements for the link belt. The link is a combination of an annular holding link that can be inserted into a bullet and a splicing link.The holding link has a connecting part protruding from one side in the link connecting direction, and the holding link is at the end of the connecting part in the protruding direction. In addition to providing a disassembling and coupling direction in the bullet insertion direction that divides the Provided on the other side of the holding link in the link connection direction is a fitting portion for fitting the connecting link corresponding to the through hole, and further, a predetermined number of holding links are provided inward on the peripheral surface of the bullet insertion side edge of the holding link. Pull of An engaging projection is provided so as to project, and a butt portion that can be opened and closed elastically is provided on one side in the link connecting direction of the joint link, and the butt portion can be inserted into the through hole through the disassembly and connection path of the holding link. A piece is projected, the joint link is inserted into the through hole of the holding link, and the joint portion of the joint link is fitted into the fitting portion of the holding link to form a link. The links are connected to each other by fitting the links into the connection holes through the disassembly and connection paths.

(Embodiment) The present invention will be described in detail with reference to the drawings showing an embodiment.
In the following description, left and right, front and rear, and up and down mean directions when holding a firearm using a link belt. The link 2 which constitutes the link belt 1 of the present invention comprises a holding link 3 and a joint link 4, and the holding link 3 is spot-welded with a left link 5 and a right link 6. A U-shaped connecting portion 7 is provided on the left side surface of the holding link 3 thus formed, and the side end surface of the connecting portion 7 is connected to the front and rear side edges 9 and 10 of the holding link 3 by the disassembly connecting path 8. A connecting hole 11 communicating with each other is formed, and a part of the upper and lower surfaces of the connecting portion 7 extends to the peripheral surface of the holding link 3 so that a through hole for a connecting link 4 described later is formed.
A through hole 12 is bored, and a fitting portion 13 corresponding to the through hole 12 is provided on the peripheral surface on the opposite side of the through hole 12. Further, a required number of engaging projections 14 are provided on the front side edge 9 of the holding link 3 so as to project inward, and as shown in FIG.
Has a springy property with the middle part being thin except for the left and right outer sides.

The joint link 4 is a circular butt link having elasticity,
A pair of connecting pieces 15 are provided at the abutting portions. The joint link 4 is opened against the elasticity against the elasticity, and the joint link 4 is inserted into the through hole 12 and fitted into the fitting portion 13 to be attached to the holding link 3. Since it is an elastic link, it is attached to the holding link in an elastically slidable state and can freely rotate within a predetermined range. In this way, the single link 2 is configured, and the connecting piece 15 of this link 2 The link belt 1 is formed by inserting a plurality of links 22 into the connecting hole 11 from the disassembling and connecting path 8 of the side link 2. As is apparent from the drawings, the link belt 1 connected in this manner is suitable because the connecting piece 15 is fitted into the elongated hole-like connecting hole 11 and the joint link 4 is mounted in a slidable state. The link 1 is disassembled because the disassembling and coupling path 8 is generally closed in the normal case, since it has the flexibility of being able to smoothly supply an unreasonable shape and does not cause defective delivery. There will be no trouble such as doing.

The bullet 16 is attached to the link 2 of the link belt 1 constructed as described above by engaging the engaging projection 14 of the holding link 3 with the sheller portion 16b of the cartridge case 16a as shown in FIG. When the bullet 16 is loaded into the firearm (not shown), the link 2 is pushed down (pulled down) and loaded separately from the link belt 1 as described above. Thus, the pushing down of the link 2 is performed by appropriately moving a movable body that operates in association with the percussion motion, for example, a barrel that moves forward and backward by the Bluff-Oward method, or a rear seat body such as a breech that rearwardly recedes. However, since the pushing-down member itself does not influence the length of the present invention, the case of pushing down by the barrel will be described in the description of the present embodiment.

In FIG. 6, the barrel 17 has been moved forward by the firing action.
Is returned to the closed position by a return spring (not shown), and the rear end of the barrel 17 hits the front side edge 9 of the holding link 3 and pushes it strongly, pulling it toward the shoulder 16b. The engaged protrusion 14 is pushed down and gets over the shoulder portion 16b. So holding link 3
The left side of is a kind of elastic link that is cut by the disassembling and coupling path 8 and the central portion is thinner than both side portions, so that the pulling protrusion 14 gets over the shoulder portion 16b, so that the resistance is extremely low. The disassembling and connecting path 8 which has been opened by pushing the disassembling and connecting path 8 which has been closed until now is pushed open and the connecting piece 15 is opened by further pushing down
Get out of and separated. The expansion of the holding link 3 is such that the through hole 12 of the connecting link 4 partially extends to the peripheral surface of the holding link 3 as shown in the drawing, and is elongated and dimensionally large. Even if 4 is fitted, it does not hinder anything. The separated link 2 is pushed down to the vicinity of the rim 16c and loaded into the barrel 17 (medicine chamber), and the cartridge case 16a to which the separated link 2 is attached after the strike is discharged as it is.

(Effect of the Invention) As described in detail above, the present invention has a strong coupling and does not separate unless necessary. On the other hand, it is very easy to separate when loading, so that problems such as defective delivery of a bullet may occur. It does not occur, has good operability, and satisfies all the requirements for link belts.
