In another embodiment of the present invention, as shown in fig. 10, the damping fixing unit 17 includes a fifth cavity portion 171, a strut 172, a through hole 173, a fifth compression spring 174, a locking bolt 175, a damping and rubber 176. The fifth cavity 171 is a stepped cavity penetrating through the bottom plate 11, a fifth compression spring 174 and a sliding column 172 are arranged in the fifth cavity, one end of the fifth compression spring 174 is pressed against the inner wall surface of the fifth cavity 171, the other end of the fifth compression spring is abutted against the top of the sliding column 172, the top of the sliding column 172 is limited in the fifth cavity 171, and the bottom of the sliding column 172 penetrates through the fifth cavity 171 and is arranged below the bottom plate 11. The bottom plate 11 can slide along the sliding column 172 by the mutual matching of the sliding column 172 and the fifth cavity part 171, and the outer side of the lower end of the sliding column 172 is provided with a damping rubber 176 which can perform secondary damping after contacting the surface of the vehicle body. Further, the strut 172 is provided with a through hole 173, and the locking bolt 175 can be abutted to a screw hole position on the vehicle body through the through hole 173, so as to fix the vehicle-mounted mounting platform 1 to the vehicle body.
With reference to fig. 11-14, the present invention further provides a fixing method of a universal fixing quick release device for military vehicle-mounted equipment, including:
s100: fixedly connecting the vehicle-mounted mounting platform 1 with a threaded hole formed in a vehicle body through a locking bolt 175 arranged on the sliding column 172, and ensuring that the vehicle-mounted mounting platform 1 is stably fixed at a position on the vehicle body, which needs to be operated and used;
s200: the carrying plate 2 is connected with the military vehicle-mounted equipment 3 through bolts to form a whole;
s300: the carrying plate 2 and the military vehicle-mounted equipment 3 are integrally pressed on the balls 164 at the top of the third limiting block 163, and the third limiting block 163 and the fourth limiting block 193 are pressed down together by pressure to enter the third cavity part 161, so that the carrying plate 2 is attached to the rollers 181;
s400: keeping the pressing chute 21 of the carrying plate 2 aligned with the second limiting block 153, and pushing the carrying plate 2 into the vehicle-mounted mounting table 1, so that the pressing chute 21 is clamped on the second limiting block 153;
s500: along the second limiting block 153, the carrying plate 2 is pushed to the first limiting block 143 until the third limiting block 163 rebounds to the original position under the action of the third compression spring 162, at this time, the third limiting block 163 is embedded in the limiting groove 22 to lock the carrying plate 2, and the fourth limiting block 193 is pushed by the fourth compression spring 192 to abut against the rear end of the carrying plate 2 and limit the carrying plate. The vehicle-mounted equipment 3 integrally fixed with the carrying plate 2 realizes omnibearing vibration reduction through the first compression spring 142, the second compression spring 142, the fourth compression spring 192 and the fifth compression spring 174, and realizes omnibearing limit clamping through the first limit block 143, the second limit block 153 and the fourth limit block 193 on the vehicle-mounted mounting platform 1;
s600: when other military vehicle-mounted equipment 3 needs to be quickly replaced on the vehicle-mounted mounting platform, the carrying plate 2 is firstly pushed to the front baffle 12 for a certain distance, so that the fourth limiting block 193 rebounds to the original position, then the third limiting type vibration reduction unit 16 is pressed into the third cavity part 161, the locking state is released, and the carrying plate 2 is pulled out of the vehicle-mounted mounting platform 1;
s700: the limiting groove 22 is held by hand, is carried to other vehicle-mounted mounting platforms 1, and is exchanged and mounted with other equipment on the carrying plate 2, so that the fixing, quick-dismantling and universalization of military vehicle-mounted equipment 3 are realized.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
