Shockproof buckle of unmanned aerial vehicle transport case

Abstract

This utility model discloses a shockproof buckle for a drone transport case, relating to the field of transport case technology. It includes a case body with a lid hinged to the top surface. A sealing groove is formed on the upper end of the inner wall of the case. Two connecting blocks are symmetrically hinged to one side of the lid's top surface, and a crossbar is fixed between the opposing surfaces of the two connecting blocks. A hanging rod is fixed to the outer wall of one side of the case body. This utility model facilitates initial locking of the lid and case body through the interlocking action of the limiting block and locking pin, improving the stability of the buckle connection and thus achieving initial fixation of the lid and case body. Furthermore, the elastic cooperation of the tension spring and telescopic tube provides continuous tension, increasing the locking force and ensuring a tight fit between the lid and case body. Ultimately, this solves the problem of insufficient locking force and poor stability of traditional buckles, which easily loosen and fall off during transportation, leading to separation of the lid and case body, thus improving the safety of the drone during transportation.

Description

Technical Field

[0001] This utility model relates to the field of transport box technology, and in particular to a shockproof buckle for a drone transport box. Background Technology

[0002] As precision equipment, the safety of drones during transportation is directly related to the integrity of the equipment and its subsequent performance. As an important protective carrier for drones, the locking force and stability of the buckle structure of the transport box are key to ensuring transportation safety. Traditional buckles mostly use rigid connection methods such as latches and pins, and their locking force relies entirely on the rigid engagement of the mechanical structure. This design has prominent problems in practical applications: if the engagement is not precise during installation, or if it is affected by vibration and bumps during transportation, the locking force is easily weakened. For example, after long-term use, the metal plate of the latch may deform due to fatigue, which will cause the engagement gap with the slot to increase, making the cover loose and even completely fall off during bumps, leaving the drone exposed and facing the risk of collision and drop damage. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

Made of nitrile rubber, it has good elasticity and sealing properties, is wear-resistant and not prone to aging. This structure, through the cooperation of the protrusion and the sealing groove 6, combined with the sealing effect of the rubber sealing gasket, can effectively prevent dust and moisture from entering the box, improving the sealing performance of the transport box and protecting the drone from the influence of the external environment. A telescopic rod 8 is hinged to the outer wall of one end of the box body 1. A limiting block 9 is hinged to the telescopic end of the telescopic rod 8. One end of the limiting block 9 is hinged to the outer wall of the box body 1 at the lower end of the telescopic rod 8. The limiting block 9 is hook-shaped. The telescopic rod 8 is made of Aishengte small hydraulic rod, which has smooth extension and extension and strong load-bearing capacity, and can stably pull back the limiting block 9. The limiting block 9 is made of 45 steel, which has high hardness after quenching treatment. The hook-shaped structure can reliably lock the locking column 10. This structure can adjust the position of the limiting block 9 through the telescopic function of the telescopic rod 8, so that it can be kept in a horizontal state to stably pull the locking column 10, providing initial locking force for the buckle and improving the stability of the buckle.

[0015] In this utility model, a locking pin 10 is engaged in the hook groove of the limiting block 9. Vertical blocks are sleeved at both ends of the locking pin 10. A sliding groove is formed in each vertical block at the locking pin 10. Rotating rings pass through the vertical blocks at both ends of the locking pin 10 and are fixed to the outer wall of the vertical blocks. A fixing sleeve is fixed to the upper end of the outer wall of each rotating ring. A tension spring 13 is installed inside the fixing sleeve. A telescopic tube 3 is fixed to the top of the tension spring 13, and the lower end of the telescopic tube 3 is located inside the fixing sleeve. The locking pin 10 is made of 304 stainless steel, which is corrosion-resistant and has high strength, capable of withstanding... The tension of the limiting block 9; the tension spring 13 is made of 65Mn spring steel, which has good elasticity and strong toughness, and can provide a continuous and stable pull force; the telescopic tube 3 is made of aluminum alloy, which is lightweight and not easily deformed, and can smoothly transmit the tension of the spring; this structure achieves initial fixation through the snap-fit ​​between the locking post 10 and the limiting block 9, and the cooperation between the tension spring 13 and the telescopic tube 3 can provide elastic tension force, enhance the locking effect of the buckle, and at the same time, the sliding groove facilitates the adjustment of the position of the locking post 10, improving the adaptability of the structure; the top of the telescopic tube 3 is hinged with a locking buckle 7, and the locking buckle 7... One end is fixed with a C-shaped buckle 5, and two corresponding fixing grooves 11 are symmetrically opened on one side of the top surface of the cover 2. The locking buckle 7 is made of spring steel, which has good elasticity and toughness, can rotate flexibly and is not easy to break. The C-shaped buckle 5 is made of high-strength plastic, which is hard and fits tightly with the fixing groove 11. This structure transmits the tension of the telescopic tube 3 to the cover 2 through the snap-fit ​​between the C-shaped buckle 5 and the fixing groove 11, further bringing the cover 2 closer to the box body 1, improving the fit between the two and enhancing the overall locking effect of the buckle.

[0016] Working principle: When using this utility model, when the transport box needs to be closed, the lid 2 is placed on the box body 1. The protrusion on the bottom surface of the lid 2 is embedded in the sealing groove 6 of the box body 1, and the rubber sealing gasket on the outer wall of the protrusion enhances the sealing performance. Then, the locking pin 10 is engaged in the hook groove of the limiting block 9, and the limiting block 9 is pulled back by the telescopic function of the telescopic rod 8 to keep the limiting block 9 in a horizontal state, thereby better holding the locking pin 10 and completing the initial fixation. At this time, the position of the fixing sleeve is adjusted by rotating the vertical block (because the rotating ring is fixed to the vertical block, rotating the vertical block can drive the rotating ring). The locking buckle 7 is manually pulled up, and the C-shaped buckle 5 at one end is engaged in the fixing groove 11 on the top surface of the lid 2. After releasing the locking buckle 7, the tension spring 13 is in the pulled-back state. Its elasticity is transmitted to the locking buckle 7 through the telescopic tube 3, further enhancing the fit between the cover 2 and the box 1; finally, the fixing post 12 is passed through the docking through hole of the locking buckle 7 and the pin hole on one side of the fixing groove 11 to achieve a stable connection between the locking buckle 7 and the cover 2; during transportation, the tension spring 13 continuously provides tension force, which, together with the pull-back action of the telescopic rod 8 on the limiting block 9 and the limiting effect of the limiting block 9, can maintain a stable state even if the buckle is affected by external forces such as vibration, effectively preventing the buckle from loosening and playing a shockproof locking effect; when it is necessary to open the transport box, remove the fixing post 12, release the C-shaped buckle 5 from the fixing groove 11, adjust the telescopic rod 8 to separate the limiting block 9 from the locking post 10, and then the cover 2 can be opened; at this point, the device is in use.
