Description

Technical Field

[0001] This utility model relates to the field of RV locks, and in particular to a security RV lock. Background Technology

[0002] As a mobile vehicle that integrates accommodation and transportation, the safety of RVs is a core concern for users. Door locks, as the first line of defense for RV security, need to meet the requirements of theft and vandalism prevention in complex outdoor environments, while also ensuring convenient operation in emergencies. Therefore, the structural reliability and security level of the locks are of a very high standard.

[0003] Currently, RV locks on the market are mainly divided into two categories: mechanical locks and electronic locks. Mechanical locks achieve locking by rotating the tumblers or leaf springs inside the lock cylinder. The core structure includes the lock cylinder, bolt, keyhole, and drive gears. When in operation, the bolt extends or retracts when the key is inserted and rotated. Electronic locks add an electronic control module. Common types include combination locks and card locks. The bolt moves when an electromagnetic mechanism is triggered by entering the correct password or a sensor card. Some also integrate remote control functions.

[0004] In existing technologies, the security of a single locking structure is insufficient: locks relying solely on mechanical rotation are easily damaged by tools or picked using technical means; simple electronic combination locks will directly lose their locking function in the event of circuit failure or malicious power outage, and electronic components are less stable in outdoor humid and high-temperature environments, easily triggering or malfunctioning, failing to provide dual security. Furthermore, the disassembly protection design of existing locks has flaws: most fixing screws and internal connecting structures are exposed or easily accessible by external tools, allowing criminals to damage the internal transmission mechanism by disassembling external components; even with concealed screws, the connection strength between the internal disassembly mechanism and the lock body is insufficient, allowing it to be pried or knocked apart, failing to effectively prevent external forced removal. Therefore, a secure RV lock is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a security RV lock, which aims to improve the problem of damaging the internal transmission mechanism by disassembling external components in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A security RV lock includes a handle, a rotating rod fixedly connected to the outside of the handle, a large gear rotatably connected to the outside of the rotating rod, a locking tooth fixedly connected to the outside of the rotating rod, a spring sleeved on the outside of the rotating rod, a long toothed rod meshing with the outside of the large gear, a lock head fixedly connected to the outside of the long toothed rod, an extension rod fixedly connected to the outside of the long toothed rod, a retaining spring sleeved on the outside of the extension rod, and the retaining spring fixedly connected to the outside of the long toothed rod.

[0008] As a further description of the above technical solution:

[0010] As a further description of the above technical solution:

[0011] The partition is fixedly connected to the outside of a shell, the shell is fixedly connected to the outside of a lower fixed plate, and the shell is rotatably connected to the outside of an upper fixed plate.

[0012] As a further description of the above technical solution:

[0013] The upper fixed plate is rotatably connected to a main rod, the main rod is threadedly connected to a rotating head, and the main rod is fixedly connected to a key.

[0014] As a further description of the above technical solution:

[0015] The main rod is slidably connected to an inner sleeve ring on its outside, and is slidably connected to an outer fixing ring on its outside. The main rod is rotatably connected to the outside of the lower fixing plate.

[0016] As a further description of the above technical solution:

[0017] The outer shell is slidably connected to an external lock door, and the internal part of the external lock door is rotatably connected to a rotary combination lock. The outer shell is also slidably connected to a sliding plate.

[0018] As a further description of the above technical solution:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a safety RV lock, including a handle 20. A rotating rod 19 is fixedly connected to the outside of the handle 20, providing a fixation for the handle 20. A large gear 23 is rotatably connected to the outside of the rotating rod 19, causing the large gear 23 to rotate. A locking tooth 21 is fixedly connected to the outside of the rotating rod 19, causing the locking tooth 21 to move. A spring 22 is sleeved on the outside of the rotating rod 19, providing elasticity to separate a long toothed rod 24. The long toothed rod 24 is meshed with the outside of the large gear 23, causing the long toothed rod 24 to move. A lock head 27 is fixedly connected to the outside of the long toothed rod 24. The lock head 27 is driven to move. An extension rod 16 is fixedly connected to the outside of the long toothed rod 24. The extension rod 16 fixes the long toothed rod 24. A retaining spring 25 is sleeved on the outside of the extension rod 16. The retaining spring 25 can separate the long toothed rod 24 and the limiter 26. The retaining spring 25 is fixedly connected to the outside of the long toothed rod 24. The long toothed rod 24 provides support to the retaining spring 25. The limiter 26 is slidably connected to the outside of the extension rod 16. The extension rod 16 slides on the limiter 26. A partition 15 is fixedly connected to the outside of the limiter 26. The partition 15 provides support to the limiter 26. The retaining spring 25 is fixedly connected to the outside of the limiter 26. The limiter 26 provides support to the retaining spring 25.

[0035] Reference Figures 4 to 6An outer lock door 4 is slidably connected to the outside of the outer casing 1. The outer lock door 4 is movably fixed in the sliding groove of the outer casing 1. A rotary combination lock 5 is rotatably connected inside the outer lock door 4, providing support for the rotary combination lock 5. A slide plate 6 is slidably connected to the outside of the outer casing 1. The slide plate 6 slides in the sliding groove of the outer casing 1. An insert plate 7 is fixedly connected to the outside of the slide plate 6. The slide plate 6 drives the insert plate 7 to move. The insert plate 7 is slidably connected inside the outer casing 1 and slides in the sliding groove inside the outer casing 1. A support rod 8 is rotatably connected inside the outer casing 1. The support rod 8 can rotate inside the outer casing 1 and provides sliding support. A slider 9 is slidably connected to the outside of the support rod 8. The slider 9 is rotatably connected to the outside of the insert plate 7. The movement of the insert plate 7 drives the movement of the slider 9.

[0036] Working principle: By rotating the combination lock 5, when the correct combination is entered, the sliding plate 6 drives the insert plate 7 to slide into the slot of the combination lock 5. The slider 9 connected to the insert plate 7 will move away from the baffle, moving the combination lock 5 to expose the internal crank handle 18. Pulling the crank handle 18 outwards and rotating it at the same time will pull the crank handle 18 outwards, causing the rotating rod 19 to be pulled outwards. This will cause the locking teeth 21, which are fixedly connected to the outside of the rotating rod 19, to move outwards. At the same time, the protrusions on the locking teeth 21 gradually move to the holes on the outer surface of the large gear 23. When the protrusions on the outer surface of the locking teeth 21 rotate to the holes on the surface of the large gear 23, rotating the crank handle 18 again will cause the large gear 23 to rotate together with the lock handle 28. As the large gear 23 rotates, the meshing long toothed rod 24 below will move together, retracting the lock head 27 outside the long toothed rod 24 to complete the unlocking. At the same time, the outer lock door 4 will fall under the action of gravity to protect the internal gear structure.

[0037] The upper fixing plate 2, which is rotatably connected to the outer shell 1, can accommodate surfaces at different angles. Rotating the rotating head 10 removes it, and then installing it inwards onto the RV. The inner ring 13 and outer fixing ring 14 are then sequentially fitted and inserted into the main rod 11. The rotating head 10 is then fitted onto the outside of the main rod 11. Rotating the rotating head 10 causes the main rod 11 to gradually tighten under the threaded connection, and the outer fixing ring 14 is fixed in place with the cooperation of the key 12. Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
