Description

Technical Field

[0001] The present invention belongs to the technical field of gun fixing devices, and more particularly, relates to a gun body fixing device, method and vehicle. Background Art

[0002] Currently, most vehicles are equipped with gun clips and fixtures located inside the vehicle or on the vehicle's inner walls, making storage and access inconvenient and limiting space. This also prevents full utilization of the vehicle's available space. In modified off-road vehicles supplied to the military, some require rifles to be securely secured within the vehicle compartment to cope with varying regional situations. This requires a rifle mount structure designed and securely and stably mounted within the vehicle compartment, facilitating easy access. In the prior art, automatic rifles are typically larger and cannot be placed freely or occupy as little space as pistols. Therefore, they typically require a fixture. However, existing automatic rifle fixtures typically present two conflicting issues: First, the automatic rifle fixture must securely hold the rifle, preventing it from loosening or falling; and second, the automatic rifle fixture must be securely mounted within the off-road vehicle and fit snugly within the vehicle. However, due to vehicle space, location, and turbulence, these two requirements are difficult to achieve. Therefore, a rifle mount is needed that both stably secures the rifle and fits snugly within the vehicle compartment.

For example, the first embracing unit 11 is provided with a plurality of first docking threaded through holes 111, and the second embracing unit 12 is provided with a plurality of second docking threaded through holes 121. In this way, according to the needs of fixing guns and the number and direction of the corresponding seats 6, different numbers of upper fixed bracket modules 2 are installed, and the direction of the upper fixed bracket module 2 is adjusted at the same time to facilitate the people on the seats to take and put the guns.

[0043] In one embodiment of the present invention, the first embracing unit 11 is provided with a first mating threaded through-hole 111 and two first weight-reducing grooves 114 on either side of the first mating threaded through-hole 111. The second embracing unit 12 is provided with two second mating threaded through-holes 121 and a second weight-reducing groove 124 between the two second mating threaded through-holes 121.

Correspondingly, the joint between the second embracing unit 12 and the first embracing unit 11 is provided with a plurality of second connecting holes 123. The number and position of the second connecting holes 123 correspond to the first connecting holes 113. By connecting bolts through the first and second connecting holes 113, the first and second embracing units 11 and 12 are connected to the column and their positions can be adjusted. In the above embodiment, the weight-reducing grooves not only reduce the weight of the components, but also provide space for the bolts to enter the mating threaded through-holes for installation. As a preferred solution of this embodiment, the mounting bolts are passed through the threaded through holes of the embracing unit and the threaded holes of the embracing unit to encircle the multiple upper fixing bracket modules 2 on the column 5. Two or more connecting holes are provided, and they can be selected according to the angles of the multiple upper fixing bracket modules 2 to adapt to the adjustment of the angles of multiple gun bodies.

[0044] In one embodiment of the present invention, a first upper protrusion 112 and a first lower protrusion are provided on the side wall connecting the first embracing unit 11 and the column 5. The first upper protrusion 112 and the first lower protrusion are spaced apart along the axis of the column 5 to form a first intermediate groove between the first upper protrusion 112 and the first lower protrusion. A second upper protrusion 122 and a second lower protrusion are provided on the side wall connecting the second embracing unit 12 and the column 5. The second upper protrusion 122 and the second lower protrusion are spaced apart along the axis of the column 5 to form a second intermediate groove between the second upper protrusion 122 and the second lower protrusion. In this way, the upper protrusion and the lower protrusion are in contact with the surface of the column 5, forming two narrow contact surfaces that can better fit the column 5.

[0045] In one embodiment of the present invention, an upper connecting straight rod 22 is provided between the upper connecting shaft 21 and the U-shaped support block 27. The aperture of the first retaining slot 25 is smaller than that of the second retaining slot 26. The thickness of the deformable structural segment 23 at the first retaining slot 25 is greater than that at the second retaining slot 26. In this embodiment, the U-shaped structure of the upper U-shaped bracket 11 is used to secure different gun barrels. It includes the following features: a threaded segment 116, a straight rod segment 115, a U-shaped support segment 117, and a deformable structural segment 118. The threaded segment 116 is coaxially connected to the end of the straight rod segment 115. The maximum diameter of the threaded segment 116 is smaller than that of the straight rod segment 115, forming a shoulder. The U-shaped support block 27 is connected to the straight rod segment 115 and is embedded within the deformable structural segment 23, serving as the framework, thereby enhancing the U-shaped clamping force of the U-shaped support block 27. The deformable structural section 23, near the inner portion, contains a first retaining groove 25, which is thicker. The deformable structural section 23, near the outer portion, contains a second retaining groove 26, which is relatively thinner.

For example, the first retaining groove 25 is used to secure a 95mm shorter barrel, while the second retaining groove 26 is used to secure a 95mm longer barrel. The thinner portion of the deformable structural section 23 housing the second retaining groove 26 enhances its ability to deform and grip the barrel. The thicker portion of the deformable structural section 23 near the first retaining groove 25 primarily enhances the first retaining groove 25's ability to grip the barrel.

[0046] In one embodiment of the present invention, the upper connecting shaft 21 includes a first Z-shaped structure, with threaded connecting rods at both ends of the first Z-shaped structure, and the threaded portion of the threaded connecting rods is provided with a locking nut. For the embracing bracket module arranged above, one end of the first Z-shaped structure is connected to the first embracing unit 11 and / or the second embracing unit 12, and the other end is connected to the upper connecting straight rod 22 and is secured by a locking nut. For the embracing bracket module arranged below, the lower connecting shaft 32 includes a second Z-shaped structure, with threaded connecting rods at both ends of the second Z-shaped structure, and the threaded portion of the threaded connecting rod is provided with a locking nut. For the embracing bracket module arranged below, one end of the second Z-shaped structure is connected to the first embracing unit 11 and / or the second embracing unit 12, and the other end is fixedly connected to the gun mount 31.

[0047] In one embodiment of the present invention, the gun mount 31 comprises a high protrusion 311 and a low protrusion 312, which connect end-to-end to form a butt-holder accommodating cavity 314. A sidewall recess 313 is also provided at the junction of the high protrusion 311 and the low protrusion 312. The gun mount 31 also comprises a lower base 33 at its bottom. In this embodiment, the lower base 33 is positioned below the gun mount 31 and contacts the floor through the lower base 33. The mounting surface of the lower base 33 includes threaded holes, allowing the gun mount 31 to be secured to the lower base 33 via bolts. Two or more threaded holes are provided on the lower base 33, which can be selected based on the angle of adjacent gun mounts 31 to adjust the angle between the two gun bodies. Furthermore, the lower connecting shaft 32 comprises a third Z-shaped structure, one end of which connects to the first mating threaded hole 111 and / or the second mating threaded hole 121, and the other end of which connects to the gun mount 31. Multiple gun mounts 31 can be positioned at different heights, allowing the upper mounting bracket module to maintain the same height while the gun mounts 31 on the lower mounting bracket module can be adjusted to different heights to accommodate guns of varying lengths. Of course, a third Z-shaped structure can also be used on the upper mounting bracket module, with the upper connecting shaft adopting the third Z-shaped structure. This allows for simultaneous height adjustment, both up and down, to accommodate larger height differences.

[0048] like Figure 8 As shown, the present invention provides a gun-mounted securing device for installation on a vehicle, particularly an off-road combat vehicle. The vehicle is equipped with a seat and a plurality of columns adjacent to the seat. The bottoms of the columns are fixedly connected to the floor of the vehicle body, and the gun-mounted securing device is mounted on the columns. More specifically, in this embodiment, the seats are arranged in two rows, each back-to-back, with the columns positioned between the rows. The gun-mounted securing device is circumferentially adjustable based on the orientation of the seats to facilitate access to and placement of the gun.

[0049] In one embodiment of the present invention, two upper fixed support modules and two lower fixed support modules are provided, and the angle between the two upper fixed support modules is less than 180°. Generally, the angle between the upper fixed support modules is 120°. Accordingly, each lower fixed support module is coaxially arranged with an upper fixed support module. More specifically, in an embodiment of the present invention, the first embracing unit and the second embracing unit can be symmetrical structures, that is, the first embracing unit and the second embracing unit have the same structure. In this case, the angle between the corresponding upper fixed support modules is 180°. Of course, in one embodiment, the first embracing unit is provided with a first docking threaded through hole, and the second embracing unit is provided with two second docking threaded through holes. In this way, three upper fixed support modules can be provided, and the angle between adjacent upper fixed support modules is 120°.
