Description

The invention relates to the field of weapons and military equipment, and specifically to armored vehicles.

The well-known hatch for firing from BTR-70 personal weapons (see BTR-70 armored personnel carrier, TO and IE, GABTU MO. - M .: Military Publishing 1988 - 560 pp. - open edition. Prototype) consists of an armor plate with an aperture, an armor plate with an axis , cam with a handle, armor plate seals mounted on the armor plate.

The hatch for firing from a personal weapon BTR-70 (hereinafter referred to as the hatch) provides targeted fire with a landing.

At the same time, frequent jamming of the opening (closing) mechanism, difficulties in positioning the armor when closing it reduce the crew’s operational efficiency, increase the duration of preparation for firing and increase the likelihood of personnel damage due to untimely closed armor.

The small opening of the hatch significantly limits the review and reduces the effectiveness of reconnaissance of targets by personnel, has a negative impact on the firepower of the BTR-70 and the combat effectiveness of the combined arms compartment as a whole.

Another drawback of the hatch is its high cost, due to the complexity of the design, the hatch contains more than ten complex parts that require high-precision equipment for manufacturing, the complexity of the hatch design also reduces the reliability of its operation.

The objective of the invention is to create options for the hatch, eliminating the above disadvantages due to a simpler and more convenient design with better capabilities for visibility and reconnaissance purposes.

The technical result of the invention is:

improving the capabilities for review and reconnaissance of targets, increasing the firepower and security of the assault force through the use of bulletproof glass with a hatch, the use of a structure with a small area of overlapping bulletproof glass;

preservation of the fire resistance of the hatch for bulletproof glass with a thickness of more than 50 cm due to the use of armored bush in the hatch structure

reducing the cost of manufacturing the hatch and increasing the reliability of the opening (closing) mechanism of the armor by simplifying the design, using a design that does not require technological equipment through the use of the "puzzle" method of assembly and fastening of parts.

The technical result is ensured by the fact that:

hatch for shooting from personal weapons, consisting of an armor plate with a hole, an armor plate with an axis, an eccentric with a handle, seals of an armor plate mounted on the armor plate, characterized in that:

in the first version

bulletproof glass with a hole up to 50 cm thick was installed in the hole of the armor plate, a sleeve in which the armor plate with an axis, an eccentric with a handle, and armor plate seal were installed;

in the second option

bulletproof glass with a hole of more than 50 cm thick was installed in the hole of the armored plate, an armored sleeve was installed in the hole, in which the armor plate with an axis, an eccentric with a handle, the armor plate seal, the armored sleeve are made of parts of the "puzzle" type, fastened with bolted joints.

The invention is illustrated figure 1-2.

Figure 1 shows the second version of the hatch for firing from personal weapons, located in bulletproof glass up to 50 cm thick.

The composition of the hatch for firing from personal weapons:

1 - armor plate with a hole;

2 - bulletproof glass with a hole;

3 - sleeve;

4 - armor plate with an axis;

5 - axis sleeve;

6 - cam with a handle;

7 - seal.

The armor plate with the hole 1 is designed to protect the landing from external factors, including damaging and fastening bulletproof glass with the hole 2.

Bulletproof glass with a hole 2 is designed to provide an overview of the landing and its protection from external factors, including damaging and mounting sleeve 2.

The sleeve 3 is fixed in the hole of the bulletproof glass 2 and is designed to protect the landing from external factors, including the damaging ones, the placement of the armor with the axis 4, the sleeve of the axis 5, the eccentric with the handle 6, seals 7.

Armored with axis 4 is intended:

to provide an overview of the landing and its protection from external factors, including the damaging ones, in the closed state (the armor plate with axis 4 is in the upper position and pressed through the seal 7 to the sleeve 3);

for firing from personal weapons - in the open position (the armor plate with axis 4 is rotated 180 degrees and is in the lower position).

The armor plate with axis 4 is installed in the sleeve 3 on the outside of the bulletproof glass 2. The axis of the armor plate is installed in the sleeve of the axis 5 with the possibility of rotation around its axis and movement along the axis, pivotally connected to the eccentric 6 on the second end of the axis.

The axis 5 sleeve is fixedly fixed inside the sleeve 3 of the armor plate with axis 4 and is intended for fastening the armor plate with axis 4 with the possibility of rotation around its axis and movement along this axis.

The eccentric with the handle 6 is pivotally connected to the axis of the armor plate 4. When lowering the handle, it rotates and abuts against the sleeve 3, forcing the armor with axis 4 to move towards the sleeve 3 and compress the seal 7.

The seal 7 is mounted on the sleeve 2 and fits snugly against the armor plate with the axis 4 and is designed to prevent dirt and precipitation from entering the machine, as well as to provide air pressure during the operation of the filter ventilation installation.
