Description

Technical Field

[0001] The utility model relates to a vehicle attachment device, in particular to a vehicle-mounted weapon seat ring supporting structure with an anti-rollover frame. Background Art

[0002] Currently, chassis-modified vehicles with rollover cages have been developed to prevent vehicles from rolling down valleys. For example, CN2787512Y discloses a "vehicle rollover prevention device," which includes protective cages symmetrically placed on either side of the vehicle chassis. These cages consist of an upper frame, side frames, and a fixed rod. The upper frames are placed on top of the vehicle and connected by an elastic mechanism controlled by the driver's cab. The upper frames' front ends are bent upward, and their rear ends are hinged to the upper ends of the side frames on the vehicle's sides. The lower ends of the side frames are hinged to one end of the fixed rod, while the other ends of the fixed rods are fixed to the vehicle chassis. When the vehicle rolls over, the protective cages fully deploy in a flat plane, changing the position of the vehicle's fulcrum and the direction of the torque, preventing the vehicle from rolling down the valley and reducing casualties and property damage. Some of these chassis-modified vehicles with rollover cages also have a weapon mount installed on top of the cages to facilitate flexible rotation and firing of the weapon in different directions. CN107990784B discloses a "turret ring for supporting artillery traverse firing," comprising a base ring and an upper ring. The ring features an annular vertical plate and several ribs fixedly connected between the base and upper rings. This design reduces weight and improves load-bearing capacity, making it particularly suitable for special vehicles.

[0003] Typically, the connection between the vehicle-mounted weapon mount support and adjacent vehicle components is a welded structure. However, if welding is still used to connect the vehicle-mounted weapon mount support to a vehicle equipped with a roll cage, welding deformation is difficult to control. The flatness of the welded support is difficult to maintain, affecting the flexible rotation of the vehicle-mounted weapon mount. Furthermore, the recoil and vibration impact of the machine gun affect the firing stability and accuracy of the vehicle-mounted weapon. Therefore, a new approach was needed. Utility Model Content

[0004] The purpose of the utility model is to provide a vehicle-mounted weapon seat ring support structure with an anti-roll frame, which can avoid the adverse effects of welding deformation, ensure the flatness of the vehicle-mounted weapon seat ring support, and thus improve the flexibility of the vehicle-mounted weapon seat ring rotation and improve the shooting accuracy of the vehicle-mounted weapon.

[0005] The utility model describes a vehicle-mounted weapon seat ring support structure with an anti-roll cage, comprising an anti-roll cage whose lower end is fixedly connected to the chassis of the vehicle, and a seat ring support plate connected to the anti-roll cage; the middle portion of the upper end of the anti-roll cage is in the shape of a square frame, and the four corners within the square frame are provided with inclined supports; the front two ends of the square frame are respectively fixedly connected to front supports, and the rear two ends of the square frame are respectively fixedly connected to rear supports; a large circular hole is provided in the middle portion of the seat ring support plate, the two front end portions are respectively provided with front support ears, and the two rear end portions are respectively provided with rear support ears; the two front support ears of the seat ring support plate correspond to the two front supports, respectively, and the two rear support ears correspond to the two rear supports, respectively, and are connected and fixed by threaded fasteners.

[0006] Furthermore, gaskets can be provided between the two front supporting ears and the two front supports and between the two rear supporting ears and the two rear supports of the seat ring support plate.

[0007] Furthermore, square pits are respectively provided in the middle of the two front supports, and front bolt through holes are respectively provided at the four corners of the two front supports; square bosses are respectively provided in the middle of the lower sides of the two front ears of the seat ring support plate, and front bolt through holes are respectively provided at the four corners of the two front ears; the square bosses of the two front ears are respectively fitted with corresponding clearances of the two square pits, and the four front bolt through holes are respectively corresponding to the four front bolt through holes, and are fastened by front connecting bolts.

[0008] Furthermore, circular pits are respectively provided on the two rear supports, and a rear bolt through hole is provided at the center of the circular pit; circular bosses are respectively provided on the two rear support ears of the seat ring support plate, and a rear bolt through hole is provided at the center of the circular boss; the circular bosses on the two rear support ears are respectively fitted with corresponding clearances of the two circular pits, and the two rear bolt through holes are respectively corresponding to the two rear bolt through holes, and are connected and fastened by rear connecting bolts.

[0009] Furthermore, the threaded connecting pieces are front connecting bolts and rear connecting bolts, both of which are 10.9 grade high-strength bolts.

[0010] Furthermore, the seat ring support plate is made of high-strength steel plate.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] The seat ring support plate is fixed to the anti-roll frame by threaded connection, thus avoiding the adverse effects of welding deformation;

[0013] Since the seat support plate is connected to the roll cage through the front and rear supports, shims can be set on the upper surfaces of the front and rear supports according to the actual gap. The number of shims can be adjusted to level the installation plane of the seat support plate, thereby ensuring the rotational flexibility of the vehicle-mounted weapon seat.

[0014] Since corresponding limiting structures are provided on the seat ring support plate and the front support at the same time, it is possible to prevent the connecting bolts from being broken by the large recoil shear force of the weapon.

[0015] The utility model has a simple structure and is easy to install, and is particularly suitable for chassis-modified vehicles with anti-rollover cages, and meets the requirements for the use of vehicle-mounted weapons. BRIEF DESCRIPTION OF THE DRAWINGS
