[0020] 2. The quick-release heavy object air-drop belt, when the aramid woven belt is inserted and guided from the middle position of the fastening sleeve and the outer rotating ring, the aramid woven belt will extrude the fastening sleeve of the cam structure to rotate around the fixed rod, so that the axis of the fixed rod rotates to the smooth arc surface of the outer wall of the fastening sleeve to the inner wall surface of the middle part of the outer rotating ring, thereby increasing the vertical distance from the inner wall surface of the middle part of the outer rotating ring to the arc surface of the outer wall of the fastening sleeve, the resistance when the aramid woven belt is inserted and guided and the tail end of the aramid woven belt is pulled for tightening is smaller, so that the tightening adjustment is easy and fast, and the operation speed of binding the air-drop heavy object is facilitated;

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0031] Please refer to Figures 1-3 The present application provides a technical solution: a quick-release heavy air-drop system belt, comprising aramid tape 1, fastener 3, quick release hook 4 and docking seat 6, one end of the aramid tape 1 is provided with sewn tape 2, the end of the sewn tape 2 away from the aramid tape 1 is sleeved with the sleeve ring of the fastener 3, the end of the aramid tape 1 extending through the quick release hook 4 is sleeved with the rubber sleeve 5, one end of the quick release hook 4 is integrally formed with the support plate 41, the other end of the quick release hook 4 is welded with the stop block 42, the end of the stop block 42 away from the quick release hook 4 is welded with the traction rod 45, the outer side of the traction rod 45 is sleeved with the tightening spring 43 welded with the stop block 42, the outer side of the tightening spring 43 is sleeved with the sheath 44, the middle surface of the traction rod 45 is provided with the threaded surface 46, the traction rod 45 is docked with the knob 47 through the threaded surface 46, the end of the traction rod 45 away from the stop block 42 is welded with the docking seat 6, the middle part of the docking seat 6 is inserted with the fixed pin 7, the inner side and the outer side of the support plate 41 are both planar structures, the opening width of the quick release hook 4 is smaller than the diameter inside the quick release hook 4, and the sheath 44 and the traction rod 45 constitute an elastic telescopic structure through the tightening spring 43.

[0032] Please refer to Figure 3 , the inner wall end of the sheath 44 is welded with the end of the tightening spring 43 away from the stopper 42, the inner wall of the knob 47 is provided with a threaded groove, the traction rod 45 and the knob 47 form a threaded structure through the threaded surface 46, and the knob 47 is a hollow tubular structure in the shape of "T"; the butt joint seat 6 is in the shape of "U", and the fixed pin 7 in the middle of the butt joint seat 6 is connected with a pull ring at one end.

[0033] In specific implementation, the air-drop material belt is used for binding and tightening of air-dropped materials or equipment, and when the air-dropped materials or equipment are landing, the materials or equipment are usually carried by air-drop pallets, and the air-drop material belt is used in cooperation with the air-drop pallet to complete the tightening and limiting of the air-dropped materials or equipment, so as to prevent the materials or equipment from falling and being damaged during air-drop landing;

[0034] After the air-drop material belt and the air-drop pallet cooperate to complete the preliminary binding of the air-dropped heavy object, the air-dropped heavy object can be slowed down and stably landed through the assistance of an aerial transportation tool, the knob 47 is loosened by manually twisting along the threaded surface 46 of the traction rod 45, so that the knob 47 is separated from the extrusion of the sheath 44, at this time, the sheath 44 is pulled in the direction of the position of the knob 47, so that the sheath 44 is lengthened when moving, thereby making the open end of the sheath 44 separate from the supporting plate 41 at one end of the quick-release hook 4, at this time, the quick-release hook 4 is exposed, and the aramid woven belt 1 can be taken out of the quick-release hook 4, thereby realizing the quick disengagement of the air-drop material belt; conversely, when the quick-release hook 4 is connected with the aramid woven belt 1 binding the air-dropped heavy object, the sheath 44 is pulled away from the quick-release hook 4, and then the quick-release hook 4 is sleeved with the aramid woven belt 1, at this time, the sheath 44 is loosened, and when the tightening spring 43 is reset, the sheath 44 can be pushed to abut against the supporting plate 41 at the end of the quick-release hook 4, so as to ensure that the open end of the quick-release hook 4 is closed, to ensure that the aramid woven belt 1 of the air-drop material belt can be quickly connected with the quick-release hook 4, and when the knob 47 is tightened, the tail of the sheath 44 is tightly pressed, so as to prevent the aramid woven belt 1 and the quick-release hook 4 from being separated due to the elastic failure of the tightening spring 43.

[0035] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, the side of the fastener 3 away from the sleeve ring is also provided with an outer rotating ring 31, a limiting protrusion 32, an inner rotating ring 33, a fixed rod 34, a fastening sleeve 35 and an anti-skid strip 36, the outer rotating ring 31 is connected to the rotating shaft on the side of the fastener 3 away from the sleeve ring, and the limiting protrusion 32 is fixed on the inner wall of the outer rotating ring 31; the inner rotating ring 33 is arranged on the inner side of the outer rotating ring 31 and connected to the rotating shaft, and the fixed rod 34 is welded to the inner side of the outer rotating ring 31 away from the rotating shaft; the outer rotating ring 31 and the inner rotating ring 33 are both U-shaped structures, and the outer rotating ring 31 and the inner rotating ring 33 are both connected to the fastener 3 through the rotating shaft to form a rotating structure, and the middle edge of the inner rotating ring 33 is provided with a protruding strip; the outer side of the fixed rod 34 is sleeved with the fastening sleeve 35, the cross section of the fastening sleeve 35 is a cam structure, and the anti-skid strip 36 is fixed on the outer wall of the fastening sleeve 35 away from the fixed rod 34; the anti-skid strips 36 on the surface of the fastening sleeve 35 are distributed at equal angles, and the anti-skid strips 36 are isosceles triangle structures.

[0036] In specific implementation, when the sewn woven belt 2 at the end of the aramid woven belt 1 is connected to the fastener 3, the tail end of the aramid woven belt 1 is inserted from the side of the outer rotating ring 31 close to the fastener 3, the aramid woven belt 1 is passed from the outer side of the fastening sleeve 35, and then the aramid woven belt 1 is led out from the opening on the side of the fastening sleeve 35 and the outer rotating ring 31 away from the fastener 3, so that the aramid woven belt 1 wraps the fastening sleeve 35, and the excess aramid woven belt 1 can be tightened by pulling the tail end of the aramid woven belt 1, so that the size of the binding port connected between the aramid woven belt 1 and the fastener 3 can be adjusted;

[0037] Since the fastening sleeve 35 adopts a cam structure and can rotate around the fixed rod 34, when the aramid woven belt 1 is inserted and led out from the middle position of the fastening sleeve 35 and the outer rotating ring 31, the aramid woven belt 1 will rub against the anti-skid strips 36 on the outer side of the fastening sleeve 35, so as to rotate the cam structure of the fastening sleeve 35 around the fixed rod 34, so that the smooth arc surface of the fixed rod 34 with a short distance to the outer wall of the fastening sleeve 35 rotates to the inner wall surface close to the middle of the outer rotating ring 31, thereby increasing the vertical distance between the inner wall surface of the middle of the outer rotating ring 31 and the arc surface of the outer wall of the fastening sleeve 35, and the resistance when the aramid woven belt 1 is inserted and led out and the tail end of the aramid woven belt 1 is pulled to tighten is smaller, so that the tightening adjustment can be easily and quickly achieved;

[0038] After the tightening adjustment is completed, the aramid fabric belt 1 is moved back a certain distance by appropriately pulling the insertion end of the aramid fabric belt 1, so that the fastening sleeve 35 of the cam structure rotates in the reverse direction around the fixed rod 34, so that the fastening sleeve 35 moves the anti-skid strip 36 on the outer wall surface to the position of the inner wall surface of the middle part of the outer rotating ring 31. At this time, the rotating fastening sleeve 35 gradually reduces the distance between the outer wall arc surface and the inner wall surface of the middle part of the outer rotating ring 31, and then the fastening sleeve 35 and the anti-skid strip 36 can clamp and limit the aramid fabric belt 1. After that, the inner rotating ring 33 is flipped over, so that the protruding strip on the edge of the middle part of the inner rotating ring 33 clamps and limits the surface of the aramid fabric belt 1 away from the anti-skid strip 36 on one side of the fastening sleeve 35, so that the distance between the protruding strip of the inner rotating ring 33 and the fixed rod 34 is also gradually reduced, ensuring that the aramid fabric belt 1 has a double clamping effect. The flipping position of the inner rotating ring 33 can be limited by the limiting protrusions 32 arranged on both sides of the inner wall of the outer rotating ring 31, to prevent the flipping angle of the inner rotating ring 33 from exceeding the clamping position;

[0039] When the aramid fabric belt 1 of the air-drop material belt is used to bind and tighten the air-drop weight for landing, the vibration of the weight on the tray will drive the weight to extrude the aramid fabric belt 1 outward, so that the aramid fabric belt 1 will be extruded by the increased binding opening. At this time, there will be a loosening phenomenon that the tail end of the aramid fabric belt 1 is pulled into the outer rotating ring 31. Since the fastening sleeve 35 of the cam structure can clamp and limit the aramid fabric belt 1 by the anti-skid strip 36 on the outer wall surface, and the protruding strip on the edge of the middle part of the inner rotating ring 33 can clamp and limit the aramid fabric belt 1, when the aramid fabric belt 1 is loosened by a single pulling force, the fastening sleeve 35, the anti-skid strip 36 and the protruding strip on the edge of the middle part of the inner rotating ring 33 can gradually tighten the wound aramid fabric belt 1, thereby preventing the air-drop material belt from loosening during the air-drop of the weight, and avoiding the shaking and falling of the air-drop materials or air-drop equipment;

[0040] When the aramid fabric belt 1 needs to be removed from the air-drop weight, the inner rotating ring 33 is rotated around the direction away from the limiting protrusion 32, so that the protruding strip on the edge of the inner rotating ring 33 is disengaged from clamping the aramid fabric belt 1. At this time, the side surface of the fastening sleeve 35 is pressed, so that the fastening sleeve 35 drives the anti-skid strip 36 to deflect in the reverse direction, so that the distance between the outer edge of the fastening sleeve 35 and the inner wall surface of the middle part of the outer rotating ring 31 increases, thereby facilitating the extraction of the aramid fabric belt 1 from the outer rotating ring 31, and thereby canceling the binding and tightening of the aramid fabric belt 1 on the air-drop weight, and facilitating the handling and use of the air-drop materials or air-drop equipment.

[0041] Please refer to Figure 1 , Figure 2 and Figure 6The arc end of the fixed pin 7 is connected to one end of the push rod 72 through a fastening screw, and the side edge of the arc end of the fixed pin 7 is welded with a guide block 71 in a right triangle structure, and the diameter of the push rod 72 is smaller than the diameter of the fixed pin 7.

[0042] In specific implementation, the arc end of the fixed pin 7 is connected to one end of the push rod 72 through a fastening screw, so that the push rod 72 can be folded around the fastening screw in the fixed pin 7, when the fixed pin 7 and the push rod 72 are in the same straight line, the fixed pin 7 is convenient to be inserted into the butt joint seat 6, when the fixed pin 7 and the push rod 72 are perpendicular to each other, the arc end of the fixed pin 7 has a limiting and anti-falling effect, and the butt joint seat 6 has a stable connection effect when the butt joint seat 6 is butted with the air drop pallet.

[0043] Please refer to Figure 6 The inside of the push rod 72 is provided with a limiting mechanism 8, the limiting mechanism 8 is composed of a stepped hole 81, a push spring 82, a hollow pressing rod 83, a transmission gear 84, a rack rod 85, a sliding block 86, a concave seat 87 and a guide wheel 88, the middle part of the push rod 72 is provided with the stepped hole 81, the stepped hole 81 is composed of a large-diameter through hole, a medium-diameter through hole and a small-diameter through hole, and the large-diameter through hole of the stepped hole 81 is fixed with the push spring 82. One end of the push spring 82 is in butt joint with the outer wall taper surface of the hollow pressing rod 83, one side of the inner wall of the hollow pressing rod 83 is provided with equidistantly distributed racks, and the other side of the inner wall of the hollow pressing rod 83 is provided with a limiting sliding groove; the medium-diameter through hole of the stepped hole 81 is installed with the transmission gear 84, one side of the transmission gear 84 is in meshing connection with the racks of the inner wall of the hollow pressing rod 83, and the other side of the transmission gear 84 is in meshing connection with the rack rod 85; the hollow pressing rod 83 forms an elastic telescopic structure through the push spring 82 and the stepped hole 81, the axis line of the rack rod 85 is parallel to the axis line of the stepped hole 81, the rack rod 85 is in sliding connection with the limiting sliding groove of the inner wall of the hollow pressing rod 83 through the sliding block 86, and one end of the rack rod 85 away from the sliding block 86 is fixed with the concave seat 87; the concave seat 87 is in sliding butt joint with the medium-diameter through hole of the stepped hole 81, one end of the concave seat 87 away from the rack rod 85 is fixed with the guide wheel 88, and the guide wheel 88 is in penetration connection with the small-diameter through hole of the stepped hole 81. Through the sliding connection of the limiting sliding groove of the inner wall of the hollow pressing rod 83 and the sliding block 86 at the end of the rack rod 85, the rack rod 85 can have a limiting and anti-falling effect when following the meshing guidance of the transmission gear 84, through the installation of the rotatable transmission gear 84 in the medium-diameter through hole of the stepped hole 81, the transmission gear 84 can prevent the angle deflection of the hollow pressing rod 83 and the concave seat 87, and can prevent the hollow pressing rod 83 from falling out of the stepped hole 81.

[0044] In specific implementation, when docking seat 6 docks with airdrop tray, lever 72 at the end of fixing pin 7 extends through docking seat 6 and is flipped and folded around fastening screw, so that guide wheel 88 inside lever 72 rolls along the outer arc surface of fixing pin 7. When guide wheel 88 moves along the inclined surface of guide block 71 with right angle triangular structure, guide wheel 88 pushes recess 87 and rack 85 into stepped hole 81 inside lever 72. When guide wheel 88 is stuck on right angle surface of guide block 71, the position of guide wheel 88 is restricted by right angle surface of guide block 71, ensuring that lever 72 continuously limits fixing pin 7.

[0045] When it is necessary to remove the fixing pin 7 from the docking seat 6, the hollow pressure rod 83 at the center of the end of the lever 72 is pressed down, causing the hollow pressure rod 83 to compress the push spring 82. This allows the hollow pressure rod 83 to drive the rack on one side of the inner wall to mesh with the transmission gear 84, causing the transmission gear 84 to drive the rack rod 85 to move in the opposite direction of the hollow pressure rod 83. At this time, the rack rod 85 will drive the recess 87 on one side of the guide wheel 88 to slide along the through hole of the stepped hole 81, thereby allowing the guide wheel 88 to be stored in the stepped hole 81. This ensures that the lever 72 can rotate back to the position of being in the same straight line as the fixing pin 7 around the fastening screw, thus quickly disengaging the airdrop strap from the tray.

[0046] In summary, during the tightening and securing of airdropped supplies or equipment, the aramid webbing 1 is wrapped around the supplies or equipment, and one end of the aramid webbing 1 is fixed to the collar of the fastener 3. Then, the other end of the aramid webbing 1 is wrapped and connected to the fastener 3. Next, the quick-release hook 4 is connected to the aramid webbing 1, and the quick-release hook 4 is pulled by the traction rod 45, so that the "U"-shaped docking seat 6 at the end of the traction rod 45 is connected to the hanging lug on the edge of the airdrop tray. Then, the fixing pin 7 is inserted and connected to the docking seat 6, thereby quickly and tightly securing the airdropped heavy objects to the airdrop tray. This airdrop securing strap can achieve tightness and anti-loosening protection for the airdropped heavy objects.
