Abstract
The utility model discloses an open ammunition belt guide device, which comprises a frame body with a rectangular section formed by encircling an upper plate, a lower plate and two side plates, wherein the internal space of the frame serves as an ammunition belt channel; the upper plate and the lower plate at the inlet of the ammunition belt channel are provided with bending ends, so that the ammunition belt inlet direction is vertical to the ammunition belt outlet direction; the bending radius of the bending end of the upper plate is greater than that of the bending end of the lower plate; and a connecting plate is fixed on the outer sides of the two side plates respectively. The open ammunition belt guide device is characterized in that: a middle part constraint guide rail is fixedly arranged on the middle part of the inner side of the lower part along the direction of the ammunition belt channel; the inner side surface of the middle part constraint guide rail extends to an ammunition belt channel inlet in a bending way along the bending end of the lower plate; and lateral constraint guide rails are fixedly arranged on the lower plates on both sides of the middle part constraint guide rail. In the utility model, the movement postures of ammunition belts can be controlled effectively in the leading-out process, the ammunition belts are stably and orderly led out along the guide rail, the turning radius is small, the occupied space is small, and faults caused by curling and blockage of the ammunition belts are avoided.
Description
Technical field
The utility model relates to a kind of machine gun chain guide device, and especially a kind of machine gun is the special-purpose chain guide device of open type ammunition belt of large-bore machine gun particularly.
Background technology
Ammunition belt is a large amount of bullets to be ined succession with series system form the ammunition chain, offers full-automatic emission machine gun or machine gun, to reach the mechanical part that continues the firepower effect.The open type ammunition belt is meant that the snap ring that is used to connect and fix bullet is the ammunition belt with semi-enclosed snap ring of opening.Chain guide device is meant the mechanism that is used for bullet emission ammunition belt derivation later.Existing machine gun particularly large-bore machine gun does not dispose chain guide device substantially under vehicle-mounted, carrier-borne, airborne platform, the ammunition belt of leaving is arbitrarily derived, and causes potential faults easily; Also there are some simple square-section chain guide devices in the prior art.For example, existing a kind of open type ammunition belt chain guide device, its structure is to comprise that the cross section that upper plate, lower plate and two side plates surround is the framework of rectangle, the framework inner space is the ammunition belt passage, upper plate at ammunition belt channel entrance place has a curved end and makes the ammunition belt importer to vertical with the ammunition belt Way out with lower plate, the curved end bending radius of upper plate is greater than the curved end bending radius of lower plate, the outside of described two side plates respectively is fixed with a connecting plate, and connecting plate is used for chain guide device is fixed on firearms.
In this chain guide device, because ammunition belt is an irregular body, for ammunition belt is passed through smoothly, so except ammunition belt took up space, remaining space was still bigger in the ammunition belt passage of framework inside, and in the ammunition belt, between each bullet snap ring for being rotatably connected, so under collision, vibrations, adjacent bullet snap ring rotates mutually into, curls and causes ammunition belt to block fault easily, functional reliability is poor.
The utility model content
At above-mentioned deficiency, technical problem to be solved in the utility model is how to provide a kind of functional reliability high open type ammunition belt chain guide device.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of open type ammunition belt chain guide device, comprise upper plate, the cross section that lower plate and two side plates surround is the framework of rectangle, the framework inner space is the ammunition belt passage, upper plate at ammunition belt channel entrance place has a curved end and makes the ammunition belt importer to vertical with the ammunition belt Way out with lower plate, the curved end bending radius of upper plate is greater than the curved end bending radius of lower plate, the outside of described two side plates respectively is fixed with a connecting plate, it is characterized in that, described lower plate middle inside is set with a middle part constraint guide rail along the ammunition belt channel direction, middle part constraint guide rail inner surface extends to ammunition belt channel entrance place along the bending of lower plate curved end, is set with the sidewise restraint guide rail on the lower plate of described middle part constraint guide rail both sides.
The utility model, be provided with middle part constraint guide rail and two sidewise restraint guide rails, make in the ammunition belt passage except ammunition belt takes up space, remaining space reduces, can effectively control the athletic posture of ammunition belt in the derivation process, ammunition belt is steadily in order derived along the guide rail direction, and radius of turn is little, it is little to take up room, avoid because the curling of ammunition belt, pile up, fault that obstruction causes.This device any fault do not occur surplus the accumulative total projectile 10,000 surplus certain type product trial assembly 30, and reliability is very high, and is respond well.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, the utility model structure as shown in Figures 1 to 4, a kind of open type ammunition belt chain guide device, comprise upper plate 1, the cross section that lower plate 2 and two side plates 3 surround is the framework of rectangle, the framework inner space is the ammunition belt passage, upper plate 1 at ammunition belt channel entrance place has a curved end and makes the ammunition belt importer vertical with ammunition belt Way out D to C with lower plate 2, the curved end bending radius of upper plate 1 is greater than the curved end bending radius of lower plate 2, the outside of described two side plates 3 respectively is fixed with a connecting plate 4, wherein, described lower plate 2 middle inside are set with a middle part constraint guide rail 5 along the ammunition belt channel direction, middle part constraint guide rail 5 inner surfaces extend to ammunition belt channel entrance place along the bending of lower plate curved end, are set with sidewise restraint guide rail 6 on the lower plate of described middle part constraint guide rail 5 both sides.Number in the figure 7 is an ammunition belt.
During concrete enforcement, described middle part constraint guide rail and the concrete size of sidewise restraint guide rail are according to the ammunition belt passage and lead the concrete size design of chain.Dimension design principle can guarantee that ammunition belt normally exports as principle when reducing ammunition belt passage remaining space as far as possible.Optimum size can contrast by experiment and obtain, and the method for these specific design sizes all belongs to general knowledge known in this field, does not belong to the place that the utility model is made contributions to prior art, is not described in detail at this.When the utility model used, 4 installations were connected on the machine gun reel cage by two connecting plates, make ammunition belt channel entrance and machine gun go out the chain mouth and connect, can guarantee that machine gun is when emission, ammunition belt can normally be derived by originally leading chain mechanism in an orderly manner, and it is very high, respond well to derive reliability.In addition, this device is specially adapted to use in the large-bore machine gun, also is applicable to simultaneously single tube, duplex, the multi-joint dress state of machine gun, and the mapped structure size also can be applicable to adopt machine gun, the machine gun of other bores of similar open type ammunition belt.
