Description

Technical Field

[0001] This invention relates to the field of strap technology, specifically a strap for airdropping heavy objects. Background Technology

[0002] During an airdrop, supplies and equipment are typically loaded onto an airdrop pallet, forming an airdrop package. This package is then placed in an aerial transport vehicle, and the supplies or equipment are dropped from the package to a designated location. When securing the airdrop package, retractable straps are usually used to tighten it, ensuring a stable drop.

[0003] When airdropped supplies or equipment are large in size and weight, multiple straps are needed to tighten them from multiple directions. The conventional method of binding is to use multiple straps to bind them in a distributed manner. However, this operation can cause the straps to scatter the supplies or equipment when binding heavy objects of different sizes and shapes, and may cause them to fall apart when landing and impacting the ground. Summary of the Invention

[0004] The purpose of this invention is to provide a heavy-load airdrop strap to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heavy object airdrop binding strap, comprising a main binding strap, a female loop, a female loop buckle, and a secondary binding strap.

[0006] The main strap and the auxiliary strap are fastened together by sewing at one end. The sewn ends of the main strap and the auxiliary strap are connected to hooks. The end of the main strap away from the hook is connected to a rope tensioner. The main strap and the auxiliary strap are respectively connected to the two side loops of the mother ring.

[0007] A secondary strap is provided on one side of the main strap. One end of the secondary strap is fastened to the auxiliary strap with stitching. The sewn ends of the secondary strap and the auxiliary strap are connected to hooks. The end of the secondary strap away from the hook is connected to a rope tensioner. The secondary strap and the auxiliary strap are respectively connected to the two side loops of the sub-ring buckle.

[0008] Preferably, two sets of connecting sleeves are embedded in the surface of the main strap and the auxiliary strap near the end of the mother ring sleeve, and fastening bolts are threadedly connected to the middle of the two sets of connecting sleeves.

[0009] The main strap and the auxiliary strap are respectively embedded and fixed with a docking seat on one side near the connecting sleeve. The docking seat is provided with an anti-loosening spring and a pin in the middle. The pin extends through one end of the docking seat and is inserted into the reserved hole at one end of the fastening bolt.

[0010] Preferably, two sets of connecting sleeves are embedded in the surface of the secondary strap and the auxiliary strap near the sub-ring buckle, and fastening bolts are threadedly connected to the middle of the two sets of connecting sleeves;

[0011] The secondary strap and auxiliary strap are respectively embedded and fixed with a docking seat on one side near the connecting sleeve. The docking seat is provided with an anti-loosening spring and a pin in the middle. The pin extends through one end of the docking seat and is inserted into the reserved hole at one end of the fastening bolt.

[0012] Preferably, limit strips are welded and fixed on both sides of the inner wall of the mother ring sleeve, and a guide opening is provided on the inner wall of the limit strip, and a reset spring is connected inside the guide opening.

[0013] Preferably, one end of the reset spring is fixed with a limit pin, and the limit pin forms an elastic telescopic structure through the guide opening of the reset spring and the limit strip.

[0014] Preferably, the limiting strips are provided in two groups of four, and the two limiting strips on the same side of the mother ring are in the same group. The limiting strips have a 120° arc structure, and there is a 60° opening between the two ends of two adjacent limiting strips. Each limiting strip has four limiting pins distributed at equal angles on its surface.

[0015] Preferably, the inner wall of the sub-ring buckle is symmetrically welded with insert rails, a fixing plate is provided between the two sets of insert rails, and two slots are opened in the groove inner wall of the insert rail.

[0016] Preferably, the insertion rail has a 60° arc-shaped structure, and the distance between the centers of the two slots on the inner wall of the insertion rail groove is the same as the distance between the centers of the two adjacent limiting pins.

[0017] Preferably, the surfaces of the main strap and the secondary strap are respectively sewn with marking tape and marking tape, and the marking tape and marking tape are both distributed in a rectangular wavy stitch.

[0018] Preferably, a sliding sleeve is provided on the outer side of the main strap, and a locking strip is embedded in one side of the sliding sleeve. The sliding sleeve is made of plastic material, and the locking strip has a concave structure.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This heavy object airdrop lashing strap connects the sub-ring buckle on the secondary strap with the mother ring on the main strap, and uses equidistant pins to lock into the grooves on the inner wall of the insertion rail, allowing the main strap and secondary strap to be assembled from multiple angles. Depending on the overall size and shape of the airdropped heavy object, one or two secondary straps can be added to the main strap. The combination of the mother ring and the sub-ring buckle can tighten the lashing strap, making the airdropped heavy object land more smoothly and preventing scattered airdropped heavy objects from scattering during landing and impact with the ground.

[0021] 2. The heavy-duty airdrop binding strap has marking tapes sewn onto the outside of the main and secondary binding straps in a rectangular wavy structure, ensuring that the horizontal writing surfaces of the marking tapes are evenly distributed. When using the binding strap to bind heavy-duty airdrop items, the corresponding numbers are marked on the horizontal writing surfaces of the marking tapes with a paint pen. This facilitates subsequent inspection and replacement based on the number of uses, ensuring that the number of binding straps used to bind heavy-duty airdrop items can be controlled, thereby preventing potential hazards when safely binding heavy-duty items.

[0022] 3. This heavy object airdrop binding strap has multiple sliding sleeves on the outside of the main strap. When using this binding strap to bind heavy objects, an elastic rope is passed through the sliding sleeves and the locking strip of the concave structure, and the elastic extension is tightened to ensure that multiple main straps used side by side can be equally restricted, preventing the main straps from loosening and slipping when binding heavy objects.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-12 This invention provides a technical solution: a heavy object airdrop binding strap, comprising a main binding strap 1, a mother ring 5, a daughter ring buckle 6, and a secondary binding strap 15. One end of the main binding strap 1 and the secondary strap 2a are fastened together by sewing. The sewn ends of the main binding strap 1 and the secondary strap 2a are connected to hooks 3a. The end of the main binding strap 1 away from the hooks 3a is connected to a rope tensioner 4a. The main binding strap 1 and the secondary strap 2a are respectively connected to the two sides of the mother ring 5. A secondary binding strap 15 is provided on one side of the main binding strap 1. One end of the secondary binding strap 15 and the secondary strap 2b are fastened together by sewing. The sewn ends of the secondary binding strap 15 and the secondary strap 2b are connected to hooks 3b. The end of the secondary binding strap 15 away from the hooks 3b is connected to a rope tensioner 4b. The secondary binding strap 15 and the secondary strap 2b are respectively connected to the two sides of the daughter ring buckle 6.

[0038] Limiting strips 51 are welded and fixed on both sides of the inner wall of the mother ring 5. The inner wall of the limiting strip 51 has a guide opening, and a return spring 52 is connected inside the guide opening. One end of the return spring 52 is fixed with a limiting pin 53, and the limiting pin 53 forms an elastic telescopic structure through the return spring 52 and the guide opening of the limiting strip 51. Insert rails 61 are symmetrically welded on the inner wall of the daughter ring buckle 6. A fixing plate 62 is set between the two sets of insert rails 61, and the fixing plate 62 is used to strengthen the structure of the two sets of insert rails 61. Two slots 63 are opened on the inner wall of the groove of the insert rail 61.

[0039] There are two sets of four limiting strips 51, with the two limiting strips 51 on the same side of the mother ring sleeve 5 belonging to the same set. The limiting strips 51 have a 120° arc structure, and there is a 60° opening between the ends of two adjacent limiting strips 51. Each limiting strip 51 has four limiting pins 53 distributed at equal angles on its surface. The insertion rail 61 has a 60° arc structure, and the distance between the centers of the two slots 63 on the inner wall of the groove of the insertion rail 61 is the same as the distance between the centers of two adjacent limiting pins 53.

[0040] For specific implementation, please refer to Figure 2 and Figure 9 It can be seen that by connecting the sub-ring buckle 6 on the secondary strap 15 with the female ring sleeve 5 on the main strap 1, the two sets of 60° arc-shaped insertion rails 61 of the sub-ring buckle 6 are inserted along the 60° openings of the two limiting strips 51, making the secondary strap 15 and the main strap 1 parallel to each other. Then, by rotating the sub-ring buckle 6, the secondary strap 15 is driven to adjust its angle. When the insertion rail 61 rotates inside the limiting strip 51, the limiting pin 53 can be pushed by the return spring 52, so that the limiting pins 53 with equal included angles can lock into the slots 63 on the inner wall of the insertion rail 61, thereby enabling the main strap 1 and the secondary strap 15 to be assembled in multiple angles.

[0041] See Figure 2 and Figure 4 It is known that when the airdropped heavy object has a relatively long and narrow box structure, the binding tightness can be adjusted by using multiple main straps 1 and auxiliary straps 2a, or multiple secondary straps 15 and auxiliary straps 2b, and by using rope tighteners 4a or 4b to tighten the main straps 1 or secondary straps 15. This facilitates one-way binding of the airdropped heavy object. Both rope tighteners 4a and 4b are existing technologies. For details, please refer to patent number 201620704839.8, which discloses a binding strap fastener with a protective cover. The principle and structure of the rope tightener in this solution are basically the same.

[0042] See Figure 1 and Figure 6 It can be seen that when airdropping a large heavy object, a main strap 1 and a secondary strap 15 are used together so that the sub-ring buckle 6 of the secondary strap 15 is connected to one side of the mother ring 5 of the main strap 1, which can bind the airdropped heavy object in a cross-hatching manner.

[0043] See Figure 8 It can be seen that when the airdropped heavy object is relatively loose, a main strap 1 and two auxiliary straps 15 are used together, so that the sub-loops 6 of the two auxiliary straps 15 are respectively connected to the two sides of the main strap 1's mother loop 5. This allows the main strap 1 and the two auxiliary straps 15 to form a cage structure to wrap the airdropped heavy object, ensuring that the strap can be tied at multiple angles.

[0044] See Figure 1 , Figure 2 , Figure 3 and Figure 10 It can be seen that two sets of connecting sleeves 7a are respectively embedded on the surface of the main strap 1 and the auxiliary strap 2a near the end of the female ring sleeve 5, and fastening bolts 8a are threadedly connected in the middle of the two sets of connecting sleeves 7a; docking seats 9a are respectively embedded and fixed on one side of the main strap 1 and the auxiliary strap 2a near the connecting sleeves 7a, and anti-loosening springs 10a and pins 11a are provided in the middle of the docking seats 9a. The pins 11a pass through and extend one end of the docking seats 9a and are inserted into the reserved hole at one end of the fastening bolts 8a.

[0045] In practice, by pulling the pin 11a to compress and shorten the anti-loosening spring 10a, the main strap 1 and the auxiliary strap 2a are respectively wrapped around the two sides of the lugs of the female ring sleeve 5. Then, the connecting sleeve 7a of the main strap 1 and the auxiliary strap 2a is threaded to the fastening bolt 8a. Then, the pin 11a is loosened, so that the return spring 10a pushes the pin 11a into the reserved hole of the fastening bolt 8a, ensuring that the connection between the main strap 1, the auxiliary strap 2a and the female ring sleeve 5 will not be loose. Conversely, by performing the reverse operation, the main strap 1 and the auxiliary strap 2a can be removed from the two sides of the lugs of the female ring sleeve 5, making it convenient to replace the main strap 1 and the auxiliary strap 2a.

[0046] See Figure 1 , Figure 2 , Figure 3 and Figure 11 It can be seen that two sets of connecting sleeves 7b are respectively embedded on the surface of the secondary strap 15 and the auxiliary strap 2b near the end of the sub-ring buckle 6, and fastening bolts 8b are threadedly connected in the middle of the two sets of connecting sleeves 7b; the secondary strap 15 and the auxiliary strap 2b are respectively embedded and fixed on one side near the connecting sleeve 7b, and the middle of the connecting seat 9b is provided with an anti-loosening spring 10b and a pin 11b, and the pin 11b passes through and extends out of the connecting seat 9b and is inserted into the reserved hole at one end of the fastening bolt 8b.

[0047] In practice, since the structural principle of the main strap 1 is the same as that of the auxiliary strap 15, the assembly method of the main strap 1 and the auxiliary strap 2a can be used when assembling the auxiliary strap 15, the auxiliary strap 2b and the sub-ring buckle 6, so as to ensure that the straps can be replaced in time after wear.

[0048] See Figure 2 , Figure 3 and Figure 12 It can be seen that the main strap 1 and the secondary strap 15 are respectively sewn together with marking tape 12a and marking tape 12b. Marking tape 12a and marking tape 12b are both distributed in a rectangular wavy stitch, and marking tape 12a and marking tape 12b extend out of the surface of the main strap 1 and the secondary strap 15 respectively and are provided with horizontal writing surfaces.

[0049] In practice, marking tapes 12a and 12b are sewn onto the outside of the main strap 1 and the secondary strap 15 in a rectangular wavy structure, respectively, so that the horizontal writing surfaces of marking tapes 12a and 12b are equidistantly distributed. When using the straps to bind airdropped heavy objects, the corresponding numbers are written on the horizontal writing surfaces of marking tapes 12a and 12b with a paint pen. This facilitates subsequent inspection and replacement based on the number of uses, ensuring that the number of straps used to bind airdropped heavy objects can be controlled, thereby preventing potential hazards when safely binding heavy objects.

[0050] See Figure 1 It can be seen that a sliding sleeve 13 is fitted on the outer side of the main strap 1, and a locking strip 14 is embedded and connected on one side of the sliding sleeve 13. The sliding sleeve 13 is made of plastic material, and the locking strip 14 has a concave structure.

[0051] In practice, multiple sliding sleeves 13 are fitted on the outside of the main strap 1. When using the strap to bind heavy objects, an elastic rope is passed through the sliding sleeve 13 and the recessed locking strip 14, and the elastic rope is tightened to ensure that multiple main straps 1 used side by side can be equally spaced, preventing the main straps 1 from becoming loose and slipping when binding heavy objects.

[0052] In summary, the airdropped heavy object is placed on a pallet, and the hooks 3a at the ends of the main strap 1 and the auxiliary strap 2a are connected to one of the connecting rings on the side of the pallet. Then, the rope tightener 4a on the main strap 1 is connected to one end of the auxiliary strap 2a, and the heavy object can be tied with a single main strap 1 and auxiliary strap 2a by repeatedly tightening the rope tightener 4a. Depending on the overall size and shape of the airdropped heavy object, one or two auxiliary straps 15 can be added to the main strap 1. The combination tightening of the straps can be achieved by cooperating the mother ring 5 and the daughter ring buckle 6, making the airdropped heavy object land more smoothly. The contents not described in detail in this description are prior art known to those skilled in the art.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
