Brief Description of the Drawings
[0006] Figure 1 It is a schematic structural diagram of the shooting port device of the present invention; Figure 2 It is a sectional view of the shooting port device with the end ring removed; Figure 3 It is a schematic structural diagram of the cover plate and the switching mechanism assembled together; Figure 4 It is a schematic structural diagram of the cover plate and the switching mechanism assembled together in Embodiment 2; Figure 5 It is a schematic diagram of a partial structure in Embodiment 3.
[0007] The present invention will be further described in detail below with reference to the drawings. Embodiments Embodiment 1
[0008] Refer to Figure 1and Figure 2 The shooting hole device includes a sleeve 1, a cover plate 2, a switch mechanism and a platform 4. The sleeve 1 is generally a hollow cylindrical tube, with a circle of protrusions 11 protruding outward at one end, and an end ring 12 is arranged at the other end of the barrel 1, and is detachably connected to the sleeve 1 through a thread. A circle of grooves 13 is arranged on the outer wall of the sleeve 1, and a sealing ring is placed in the groove 13. When the sleeve is installed on the armored vehicle, the sealing ring is stuck between the sleeve and the body plate of the armored vehicle to play a sealing role. The inner wall of the sleeve 1 is provided with a platform 4, and the top surface of the platform 4 is a plane, so as to facilitate the installation of guns and increase the comfort of shooting. The platform 4 is integrally formed with the sleeve 1, and the material can be engineering plastics, reinforced engineering plastics or composite materials. Engineering plastics include but are not limited to nylon, PBT, ABS or PEEK and other materials. Reinforced engineering plastics can be reinforced engineering plastics including nylon and glass fiber, or reinforced engineering plastics including nylon and carbon fiber. Composite materials include but are not limited to materials such as glass fiber or carbon fiber. The material of the platform and the sleeve is preferably a reinforced engineering plastic comprising nylon and glass fiber, wherein the mass of the glass fiber accounts for 5-50% of the total mass of the reinforced engineering plastic. Nylon has relatively high impact strength and tensile strength, and is relatively excellent in abrasion resistance, chemical resistance and solvent resistance. Reinforcing nylon with glass fiber can reduce the water absorption rate of the product, increase the heat deformation temperature and dimensional stability, and further improve the surface hardness, tensile strength, bending strength and abrasion resistance.
[0009] The sleeve 1 and the platform 4 are integrally formed by injection molding, preferably by the following method: (1) The raw materials are fully mixed and dried at 100-150°C for 2-6 hours. The raw materials are reinforced engineering plastics including nylon and glass fiber, and the mass of the glass fiber accounts for 5-50% of the total mass of the reinforced engineering plastics; (2) Pour the dried raw materials into the mold and perform high-temperature and high-pressure molding at a pressure of 50-120 MPa and a temperature of 200-350°C for 1-10 minutes; (3) Take the molded product out of the mold and soak it in warm water for 1-6 hours.
[0010] The platform and sleeve are integrally formed with a material that is cheaper and lighter than metal, which greatly reduces weight and reduces costs, and is very convenient to install and disassemble; the one-piece molding process has a fast processing speed and high production efficiency, further reducing costs.
[0011] See also Figures 1 to 3, the switch mechanism includes a connecting rod 6, a compression spring 7, and a handle 8. The platform 4 is provided with a through mounting hole, and an inner hole boss protruding inward is provided in the mounting hole. The connecting rod 6 passes through the mounting hole, and both ends are outside the mounting hole. A boss 61 protruding outward is provided on the connecting rod 6. The compression spring 7 is placed in the mounting hole of the platform 4, and the connecting rod 6 passes through the compression spring 7. The compression spring 7 is placed under compression between the inner hole boss of the mounting hole of the platform 4 and the boss 61 of the connecting rod. The cover plate 2 is on the outer side of the sleeve, circular, with a diameter larger than the aperture of the sleeve, and is used to close the barrel hole of the sleeve. The outer end of the connecting rod 6 is connected to the cover plate 2, and the inner end is hinged to the handle 8. The handle 8 can rotate relative to the connecting rod 6 around the hinge axis 80. The handle 8 is outside the sleeve and the platform 4 and remains in contact with the end face of the platform 4 so that the compression spring 7 is in a compressed state. The handle 8 includes a near contact surface 81 and a far contact surface 82. Both the near contact surface 81 and the far contact surface 82 are flat surfaces. The distance from the near contact surface 81 to the hinge axis 80 is shorter than the distance from the far contact surface 82 to the hinge axis 80. By rotating the handle 81, either the near contact surface 81 or the far contact surface 82 can be pressed against the end face of the platform 4. A magnet 9 is provided on the outer side of the far contact surface 82 of the handle 8, and a notch 62 is provided on the connecting rod 6. The magnet 9 can be inserted into the notch 62. When the far contact surface 82 of the handle 8 is pressed against the end face of the platform 4 (as shown in Figure 1 , Figure 2 ), the distance that the connecting rod 6 extends towards the handle 8 end is longer, the compression spring 7 is compressed shorter, the cover plate 2 is in a state of closing the sleeve, the magnet 9 is inserted into the notch 62 of the connecting rod 6, the magnet 9 attracts the connecting rod 6, and the handle 8 is locked to prevent accidental operation of rotating the handle to open the cover plate, making the armored vehicle safer.
[0012] See Figure 1 and Figure 2, To prevent the platform from deforming due to heat, a heat insulation structure is provided on the top of the platform 4. In this embodiment, the heat insulation structure is a gun rack. The gun rack includes a base 51, a universal ball 52, and a frame body 53. Threaded holes are provided on the base 51 and also on the platform 4. By matching the screws with the threaded holes on the base 51 and the platform 4, the base 51 is detachably mounted on the platform 4. The base 51 has a mounting groove, and the universal ball 52 is arranged in the mounting groove. The shape of the mounting groove is adapted to the spherical surface of the universal ball 52, so that the universal ball 52 can rotate up, down, left, and right relative to the base 51 and will not fall out. The frame body 53 is connected to the universal ball 52 and has a U-shaped groove that penetrates at both ends at the top. When shooting is required, the gun barrel is placed in the groove. The gun rack provides a stable support for the gun barrel, and by rotating the universal ball, the angle of the frame body can be adjusted, thereby adjusting the shooting angle. The gun rack can further improve the comfort of holding the gun and shooting, and improve the shooting accuracy. The installation and disassembly of the gun rack are very convenient, and it can be selected to be installed or not installed according to actual usage needs. In the case of continuous shooting for a long time, the temperature of the gun barrel will be very high. The gun rack is made of metal and can withstand the high temperature of the gun barrel to prevent the platform from deforming due to heat when the gun barrel is directly placed on the platform.
[0013] One end of the platform 4 near the handle 8 has a protrusion 40. The protrusion 40 extends outside the sleeve. The mounting hole of the platform penetrates the protrusion 40, and the handle 8 presses on the protrusion 40.
[0014] During installation, first remove the end ring 12, insert the cylinder body 1 into the shooting hole of the armored vehicle from the outside of the armored vehicle. The protrusion 11 of the sleeve abuts against the armored vehicle body. A gasket can be provided between the protrusion 11 and the armored vehicle body, and then install the end ring 12 on the cylinder body 1 inside the armored vehicle. When shooting is not required, the cover plate 2 is in a state of closing the sleeve, as Figure 1As shown in the figure, at this time, the far contact surface 82 of the handle presses on the end surface of the protrusion 40 of the platform 4. The distance that the connecting rod 6 extends towards the end of the handle 8 is longer, the compression spring 7 is compressed shorter, the magnet 9 attracts the connecting rod 6, and the handle is self-locked. When shooting is required, the cover plate 2 needs to be opened. Rotate the handle 8 upwards around the hinge axis so that the near contact surface 81 presses on the end surface of the protrusion 40. The cover plate 2 and the connecting rod 6 move a certain distance towards the outside of the armored vehicle together. The cover plate 2 leaves the mouth of the sleeve but blocks directly in front of the mouth of the sleeve. Then rotate the handle 8 180 degrees around the connecting rod 6, and the connecting rod 6 and the cover plate 2 also rotate together. The cover plate 2 rotates below the top surface of the platform 4, and the mouth of the sleeve is completely exposed to the outside. Place the firearm on the platform 4 or on the gun rack, and then it can be fired outwards. When it is necessary to close the cover plate 2 after shooting, rotate the handle 8 180 degrees in the reverse direction around the connecting rod 6. The cover plate 2 returns to the position directly in front of the mouth of the sleeve. Rotate the handle 8 downwards around the hinge axis so that the far contact surface 82 presses on the end surface of the protrusion 40. The cover plate 2 and the connecting rod 6 move a certain distance towards the end of the handle 8 together. The cover plate 2 covers the mouth of the sleeve, the magnet 9 attracts the connecting rod 6, and the handle is self-locked. When the cover plate covers the mouth of the sleeve, the far contact surface of the handle presses on the end of the platform. When the cover plate opens the mouth of the sleeve, the near contact surface of the handle presses on the end of the platform. Both the far contact surface and the near contact surface of the handle are flat surfaces. Whether the cover plate is closed or opened, it is in a stable state.
[0015] Embodiment 2 See Figure 4 , the difference between this embodiment and Embodiment 1 is that the magnet 9 has a concave arc surface, there is no notch on the connecting rod 6, and the arc surface of the magnet 9 is adapted to the cylindrical outer surface of the connecting rod 6. When the cover plate closes the sleeve, the far contact surface 82 of the handle 8 presses on the end surface of the platform 4, and the arc surface of the magnet 9 attracts on the outer surface of the connecting rod 6. The magnetic attraction force between the magnet 9 and the connecting rod 6 is stronger, and the self-locking effect of the handle is better.
[0016] Embodiment 3 See Figure 5 , in this embodiment, the heat insulation structure is the metal plate 5. The metal plate 5 is arranged on the top surface of the platform 4, and convex strips 50 are arranged on the metal plate 5. There is a dovetail-shaped slot on the platform 4. The convex strip 51 on the metal plate 5 can be inserted into the slot, and the metal plate is detachably installed on the platform through the pluggable connection between the convex strip 50 and the slot. To further protect the platform, a heat insulation pad can also be laid on the platform.
[0017] The shooting hole device provided by the present invention integrally forms the platform and the sleeve with materials that are cheaper and lighter than metal, greatly reducing the weight and cost, and being very convenient for installation and disassembly; a platform is arranged on the inner wall of the sleeve, and the switching mechanism is arranged on the platform, and a simple mechanical structure is adopted to control the opening and closing of the cover plate, and the operation is very simple and convenient. All structures are integrated on the sleeve, which is convenient for installation, storage and transportation. When the cover plate is closed, the handle is self-locked through the cooperation of the magnet and the connecting rod, which can effectively prevent the cover plate from being accidentally opened, and the safety of the shooting hole device is greatly improved. When shooting, the gun is placed on the top surface of the platform or on the gun rack, and it is more comfortable to hold the gun and shoot. The gun rack and the metal plate can prevent the heat generated by shooting from directly reaching the platform and prevent the platform from being deformed due to heat.
