Description

Technical Field

[0001] This invention patent relates to a rifle device for concealed combat. Background Art

[0002] In modern warfare, due to the development of weapon aiming technology, the aiming devices of rifles for individual combat are very precise and have all-weather functions. Once a target is detected, it can effectively hit the opponent. After the existing rifles are equipped with aiming devices, they can all achieve the effect of accurately killing the opponent. However, due to the requirements of its own structure, a rifle must expose the body during combat to observe the battlefield environment, aim at the opponent, and fire. This combat method has also become the target of the opponent's aiming and attack. In war, the phenomenon of casualties caused by such exposure of body parts accounts for a large proportion, and it is also the main factor for the reduction of combat effectiveness. In order to reduce casualties, can the existing rifles be made to both kill the opponent and not be seen by the enemy, conceal oneself, and protect combat personnel from casualties to ensure victory in the war? This is the most urgent problem to be solved. This invention relates to a rifle device for concealed combat, which is composed of a belt assembly, a bracket, a moving assembly, a chassis assembly, a simulated gun body assembly, a display bracket assembly, a video display, a display video cable, a rear rotating rod assembly, a gun rack assembly, a video base assembly, a rifle, a front rotating rod assembly, a sleeve assembly, and a tripod assembly. When in combat, this device can ensure that the body of the combat personnel is not seen by the enemy, conceal oneself, and at the same time observe the battlefield situation, aim at the enemy, and strike the enemy, reducing the casualties of the troops and ensuring victory in the war. Summary of the Invention

[0003] Objective of the present invention: A rifle device for concealed combat, which can use a bunker to protect the body of combatants from being seen by the enemy during combat, and can normally observe the battlefield situation, aim at the enemy and strike the enemy, reducing the casualties of troops. When combatants need to stand and fight in a trench or behind other bunkers, the device can be fixed to the waist, and the rifle is fixed on the gun mount assembly of the sleeve assembly supported by the bracket. A camera, a video connector tube, and a video base assembly are installed on the gun mount assembly. The video monitor is connected below the outer sleeve. The camera is aligned with the rifle sight under the protection of the light-shielding and rain-sheltering of the video connector tube, or under the condition of installing a telescopic sight, the video connector tube is connected to the eyepiece of the telescopic sight to aim at the target. The human body hides behind the bunker and manipulates the simulated gun body assembly below the outer sleeve to view the observed target on the video monitor. Utilizing the rotation function connected by the sleeve assembly, the chassis assembly, and the moving assembly, and the four-link structure of the front and rear rotating rod assemblies to control the left and right rotation and up and down movement of the rifle. The human body itself can also rotate with the above device. Using the Bowden cable principle, the Bowden cable is used to simulate the trigger to control the rifle trigger, completing the operation that the human body hides under the bunker, the rifle observes, aims at the target and strikes the target above, and the operation of the rifle is below the bunker. The rise and fall of the remote-controlled sleeve structure are carried out below the bunker to observe the battlefield situation, aim at the target and fight. The body part will not be seen by the enemy. When encountering a relatively low bunker or when lying down to fight, the chassis and sleeve structure on the bracket can be directly carried down, and the three folding legs of the chassis are opened and placed behind the bunker or on the ground. The combatant can lie on the ground or behind the bunker and remotely control the rifle to strike the enemy. When corner shooting at the enemy is needed, the simulated gunstock fixing cap is opened. At this time, the connecting body of the simulated gunstock a body and the simulated gunstock b body can be separated from the simulated gunstock c body. At this time, the upper and lower fixing straps of the connecting body of the simulated gunstock a body and the simulated gunstock b body can be fixedly guided and rotated with the moving strap on the simulated gunstock c body. The angle formed by the connecting body of the simulated gunstock a body and the simulated gunstock b body and the target is the shooting angle at the target. After adjusting the distance between the fixing strap required for body concealment and the simulated gunstock c body and tightening the simulated gunstock fixing cap, the body is concealed on the side of the corner bunker shield. The sleeve rifle assembly supported by the bracket is adjusted and pushed forward to the end of the bracket through the moving assembly, away from the body to a safe distance. The body hides on the side of the bunker shield so that the enemy cannot see it. The combatant can see the target on the other side of the corner through the video on the sleeve rifle assembly supported by the bracket and strike. The above three combat methods cover the basic ways of rifle combat. Therefore, the device can conceal combatants, strike the enemy, reduce the casualties of troops, and provide guarantee for winning the war.

Insert the connecting pipe a plug 9-1 of the rear rotating rod assembly 9 into the square hole of the inner sleeve of the gun handle module bearing. Insert the connecting pipe a plug 9-1 of the front rotating rod assembly 13 into the square hole of the inner sleeve of the gun body module bearing. Align the concave and convex grooves of the chassis body 4-3 and the fixed disk 3-2 and install them. In this way, the device fixed by the belt is installed. During the operation, when the human body hides behind a shelter or in a trench, whether standing or kneeling, the body can be masked by raising and lowering the inner sleeve 14-8, which is remotely controlled by the crank 14-14-9. After observing the battlefield situation seen in the upper video and determining the height of the target position, open the connecting pipe fixing sleeves 9-3 of the front and rear rotating rods, and insert the connecting pipe b plugs 9-1 into the square holes of the front rotating rod socket bearing 5-14 and the rear rotating rod socket bearing 5-13 respectively. Since the rotating rod is a small tube set inside a large tube, after adjusting the length, it is fixed by the connecting pipe fixing sleeve 9-13. In this way, the inner sleeve 14-8 is fixed according to the target height, and the lengths of the front and rear rotating rods are fixed. At this time, the human body shoots at the target seen on the simulated gun body assembly 5 through the video monitor 7. The simulated gun body assembly 5 can rotate left and right. When the simulated gun body assembly 5 rotates left and right, the sleeve plug 5-23 of the simulated gun body drives the device on the outer sleeve to rotate together. When the simulated gun body assembly 5 moves up and down, due to the connection of the front and rear rotating rod assemblies,It becomes that the rifle rotates through the gun mount bearing, simulating that the gun body assembly 5 rotates through the sleeve plug bearing 5-24, and the front and rear rotating rods rotate through the buttstock module bearing 10-7, the gun body module bearing 10-5, the rear rotating rod socket bearing 5-13, and the front rotating rod socket bearing 5-14. In this way, it becomes a four-link motion. The movement of the gun body assembly up and down is simulated, and the rifle moves accordingly, achieving an integrated movement. This ensures that the body is shielded under an object or in a trench during combat and not visible to the enemy, while the combatant can see the enemy and strike the enemy. When it is necessary to be fixed in one place for defensive combat, separate the chassis body 4-3 from the fixed plate 3-2, open the inner sleeve cover 14-9, take out the tripod assembly 15, connect the connecting bolt 15-1 on the tripod to the tripod threaded hole 4-8 on the chassis, fix the tripod assembly 15, and adjust the height of the inner sleeve. In this way, the combat can be supported by the tripod. When it is necessary to be shielded on the ground or behind a very low shelter, separate the chassis body 4-3 from the fixed plate 3-2, open the three folding legs 4-1 on the chassis body, support them on the ground, and lie prone on the ground or behind a low object. In this way, the simulated gun body assembly 5 can also be operated for combat. When encountering a corner shooting situation, open the fastening knob 3-6 of the moving assembly 3, push the device above to the top in front of the bracket 2 with the push rod 3-1, tighten the fastening knob 3-6, unscrew the simulated buttstock fixing nut 5-17, and pull open the required distance through the moving bar guiding fixed column 5-18. At this time, the simulated buttstock a body, the simulated buttstock b body, and the moving bar 5-16 are integrated and then rotated. The angle formed with the simulated buttstock c body is the angle required between the human body and the corner target. Then tighten the simulated buttstock fixing nut 5-17, rotate the display to an angle where you can see it. At this time, the shooting direction of the rifle is the target direction, the body is on the side of the corner and blocked by the corner. Hold the combination of the simulated buttstock a body, the simulated buttstock b body, and the moving bar 5-16. See the target through the display, and operate this combination to shoot the target. In this way, the simulated buttstock assembly 5 is fixed. At this time, the simulated buttstock assembly 5 held in front of the body forms the required striking angle with the shooting direction of the rifle. Using the distance between the bracket and the body, after the human body hides on one side of the corner object, the bracket 2 extends to expose the enemy's position that can be seen. In this way, operate the simulated gun body assembly 5 to strike the enemy on the side and rear of the corner object. When it is necessary to hold the rifle, separate the chassis body 4-3 from the fixed plate 3-2, pull out the front and rear rotating rod sockets, open the gun handle fixed rotating hook 5-6-1, remove the module, open the buttstock mold loss fixing hook 10-11, open the gun body module fixing hook 10-15, and remove the rifle. Then the rifle can be normally held by hand. This device realizes a waist-fixed rifle combination device, which can lift and lower the rifle, shield oneself, and operate the rifle through the operation of the simulated gun body assembly, including aiming and moving up, down, left, and right, observing all the actions of the enemy through the video display to capture and aim at the target, and realizing the trigger operation through the Bowden wire.By utilizing the extension distance of the bracket outside the body and the rotation of the fixed rifle combination device, it is possible to strike the enemy around the corner while concealing oneself. By using the function that the chassis and the fixed disk can be disassembled and combined, and the three folding legs, the requirements for rapid kneeling and lying shooting can be achieved. At the same time, the body is concealed behind a relatively low bunker or on the ground, and the functions of the device are operated to strike the enemy and protect oneself. By using the space of the inner sleeve, a triangular bracket is placed, and the fixed rifle device is supported and fixed with a tripod at the place where fixed defense is required, and the functions of the device are operated to achieve protecting oneself and striking the enemy.

[0007] The beneficial effects of the present invention are as follows: It solves the problem that during combat, when aiming at the enemy's body with a firearm, one must expose oneself in front of the enemy, resulting in a large number of casualties being directly targeted and shot by the enemy. This device can be used in trenches, behind cover, at corners, behind low objects, etc. It can conceal oneself, observe the battlefield situation, aim at the enemy, and can operate a rifle to strike the enemy, greatly reducing casualties. Especially when facing modern rifles with sniper capabilities, exposing the body means casualties. This device, with the characteristics of strong support and load-bearing capacity at the waist, uses a waist belt to fix and bear the weight of the rifle. In the form of a triangular bracket for load-bearing, the weight of the rifle and the device is concentrated on the load-bearing waist belt at the waist. At the same time, the length of the bracket can be adjusted for distance. When shooting with the simulated stock assembly, each person needs to adjust the distance according to their different body conditions. The triangular bracket also solves the problem of forming an angle of any degree with the body by moving the rifle away from the body to shoot at a position. It enables one to conceal oneself at a corner and operate the rifle to strike the enemy. The way of fixing this device with a waist belt can meet the combat needs for rapid movement and running without any restrictions, and can aim and strike the enemy at any time. When encountering a low cover or needing to lie down and shoot, separate the chassis assembly and the above device from the mobile assembly, open the three folding legs and support them on the ground. The human body can operate the device to shoot the enemy in a kneeling or lying position. When needing to hold a position for a long time, open the inner sleeve cover, take out the tripod assembly, separate the chassis assembly and the above device from the mobile assembly, connect them with the tripod connection bolt to the tripod connection threaded hole on the chassis body, open the tripod legs, and operate the device to conduct combat, relieving the human body from the load-bearing state. During normal marching, the waist belt can be untied, and the bracket and the above device can be rotated to the back of the body and fixed again, facilitating marching. This device uses a ratchet assembly to fix the outer sleeve to lift and lower the inner sleeve through auxiliary settings such as pulleys, steel wires, pulley fixing frames, and steel wire chutes to complete the capture of the enemy target by the rifle. The gun rack jack on the inner sleeve is connected to the gun rack assembly. The gun handle module and the gun body module on the gun rack assembly fix the rifle on the gun rack. The simulated gun body assembly connects the Bowden wire, gun handle fixing assembly, Bowden wire simulated trigger fixing frame, connection bolt, tension spring, Bowden wire simulated trigger rotation shaft, and connects the Bowden wire simulated trigger to the trigger push piece to move, realizing the shooting operation of the simulated gun body assembly on the rifle. Insert and connect the dovetail groove concave groove of the video base assembly to the dovetail convex groove on the gun handle module. The camera and the video device connecting cylinder are aligned with the rifle sight or the aiming scope under the adjustment of the video height adjustment knob. When using the aiming scope, the video device connecting cylinder is sleeved on the eyepiece of the aiming scope. One end of the display video line is connected to the camera, and the other end is connected to the video display. The display support assembly is installed on the outer sleeve. When the simulated gun body assembly operates and shoots, it can see the target aimed by the rifle through the video display, realizing the operation of the rifle to observe the enemy's battlefield situation and aim at the target under the condition of concealing the body.The square gun rack plug on the gun rack assembly is inserted and connected to the square gun rack socket on the inner sleeve. The square socket of the inner sleeve of the buttstock module bearing on the gun rack assembly is inserted and connected to the square plug on the rear rotating rod assembly. The square socket of the inner sleeve of the gun body module bearing is inserted and connected to the square plug on the front rotating rod assembly. The square sleeve plug of the simulated gun body assembly is inserted and connected to the square sleeve socket on the outer sleeve. The gun handle fixing assembly is fixed to the rifle handle. During combat, the target height for aiming the rifle is adjusted through the video display. The connecting pipe fixing sleeve is opened, and the square plug at the other end of the rear rotating rod assembly is inserted into the square hole of the rear rotating rod socket bearing on the simulated gun body assembly. The other square plug of the front rotating rod assembly is inserted into the square hole of the front rotating rod socket bearing on the simulated gun body assembly. The connecting pipe fixing sleeve is tightened respectively. When the simulated gun body assembly rotates up and down, the connected front rotating rod assembly and rear rotating rod assembly drive the gun rack assembly to rotate through the gun rack bearing, and the rifle on the gun rack assembly rotates together, realizing the operation of the up and down movement of the rifle when the body is sheltered. The simulated gun body assembly can also rotate the outer sleeve to drive the left and right rotation of the rifle. This function ensures that when shooting around a corner, the body is sheltered behind an object, and the rifle can rotate left and right, realizing the function of shooting around a corner together with the above-mentioned up and down movement. The device uses a plastic shell and frame made by self-manufacturing molds, which is light in weight and convenient to carry, solves the problem of sheltering the body and attacking the enemy under various combat conditions, effectively reduces the casualties of combat personnel, preserves the combat effectiveness, and guarantees winning the war. Since the use of rifles in combat, the most casualties in historical wars have been caused by combat personnel having to attack the enemy under the condition of exposing their bodies, and being effectively injured or killed under such conditions, which is the largest and most main way of sacrifice in war. The present invention effectively solves the above problems. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 It is an assembly drawing.

At this time, the simulated buttstock a body, the simulated buttstock b body, and the moving bar 5-16 are integrated and then rotated to form an angle with the simulated buttstock c body, which is the angle required between the human body and the corner target. Then tighten the simulated buttstock fixing nut 5-17, rotate the display to an angle where you can see it. At this time, the shooting direction of the rifle is the target direction, the body is on the side of the corner and blocked by the corner, and what is held is the combination of the simulated buttstock a body, the simulated buttstock b body, and the moving bar 5-16. Observe the target through the display and operate this combination to shoot the target. In this way, the simulated buttstock assembly 5 is fixed. At this time, the simulated buttstock assembly 5 held in front of the body forms the required striking angle with the shooting direction of the rifle. Using the distance between the bracket and the body, after the human body takes shelter on one side of the corner object, the bracket 2 extends to expose the enemy's position that can be seen. In this way, the simulated gun body assembly 5 is operated to strike the enemy on the side and rear of the corner object. When it is necessary to hold the rifle, separate the chassis body 4-3 from the fixed disk 3-2, pull out the front and rear rotating rod sockets, open the gun handle fixed rotating hook 5-6-1, remove the module, open the buttstock mold loss fixing hook 10-11, open the gun body module fixing hook 10-15, and remove the rifle. Then the rifle can be normally held by hand. This device realizes a waist-fixed rifle combination device, which can lift and lower the rifle, shelter oneself, and use the operation of the simulated gun body assembly to realize the operation of the rifle, including aiming and moving up, down, left, and right, observing all the actions of the enemy through the video display to capture and aim at the target, and realizing the trigger operation through the Bowden cable.By utilizing the extended distance of the bracket outside the body and the rotation of the fixed rifle assembly, you can attack the enemy around corners and hide yourself. By utilizing the detachable and combined function of the chassis and fixed plate and the three folding legs, you can achieve the requirements of fast kneeling and lying shooting. At the same time, you can hide behind a low bunker or on the ground and operate the function of the device to attack the enemy and protect yourself. The space in the inner sleeve can be used to place a tripod. Use the tripod to support the fixed rifle device in the place where it needs to be fixed and hold. Operate the function of the device to protect yourself and attack the enemy.
