Description

Technical Field

[0001] This utility model belongs to the technical field of trailer accessories, specifically relating to an adjustable trailer ball cover adaptive locking device. Background Technology

[0002] As people's living standards continue to improve, RV travel has gradually transformed from a relatively niche travel option into a popular choice for the general public. Towable caravans, as one of the mainstream categories, are favored by users for their high space utilization and flexibility. However, their inherent drawbacks are also quite prominent: when the vehicle is parked, any external vehicle can easily tow it away using a simple trailer, leading to a significant risk of theft. However, most towable caravans do not come equipped with effective anti-theft devices at the factory, and this security vulnerability has created a demand for targeted anti-theft equipment in the market. Utility Model Content

[0003] The present invention aims to provide an adjustable trailer spherical cover adaptive locking device to solve the technical problem that existing towed caravans are not equipped with effective anti-theft devices.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An adjustable trailer hoop cover adaptive locking device includes a ball head lock body, a lock cylinder and a hoop lock. The ball head lock body has a tubular structure. One end of the ball head lock body is an open end. The other end of the ball head lock body is provided with an end panel with an opening. A first lock lug is also fixed on the end panel. The first lock lug extends outward from the opening of the end panel and has a lock hole.

[0006] The lock cylinder is provided with a ball head and a second lock lug at the end, and the second lock lug has a second lock hole;

[0007] The lock cylinder is inserted into the ball head lock body through its open end, so that the second lock lug of the lock cylinder protrudes outward from the opening. At this time, lock hole one and lock hole two correspond to each other. The ice hockey lock achieves the locking of the lock cylinder and the ball head lock body by cooperating with lock hole one and lock hole two.

[0008] Furthermore, a protective cover is fixed to the end panel, with an opening inside the protective cover, which is used to protect the hockey lock.

[0009] Furthermore, a rubber sleeve is provided on the outer side of the protective cover.

[0010] Furthermore, the lock cylinder is made of copper, and the ball-head lock body is made of aluminum alloy.

[0011] Furthermore, several drainage grooves are provided on the ball-head lock body.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model effectively solves the core security problem of the ball joint of a towed caravan being easily illegally attached and stolen by means of a stacked locking structure of the first and second locking lugs, combined with the concealed protection design of the protective cover for the ball joint lock; the innovative combination of an aluminum alloy ball joint lock body and a copper lock cylinder significantly improves the corrosion resistance in outdoor environments, and the drainage channel design completely eliminates the risk of internal water accumulation; the overall structure ensures anti-theft strength while taking into account rust prevention, drainage, and ease of operation. This utility model not only improves the anti-theft security of the caravan when parked outdoors, but also increases the product's service life and reduces maintenance costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] The present invention will be further described in detail below with reference to the embodiments.

[0021] like Figure 1-5 As shown, a specific embodiment of the adjustable trailer ball cover adaptive locking device provided by this utility model is as follows:

[0022] An adjustable trailer ball cover adaptive locking device includes a ball head lock body 1, a lock cylinder 2, and a hockey lock 3. The ball head lock body 1 has a cylindrical structure. One end of the ball head lock body 1 is an open end, and the other end of the ball head lock body 1 is provided with an end panel 4. The end panel 4 is provided with an opening 5. A protective cover 6 and an L-shaped first lock lug 7 are also welded to the end panel 4. The opening 5 is located inside the protective cover 6. The first lock lug 7 extends outward from the opening 5 of the end panel 4. A lock hole 8 is provided on the first lock lug 7.

[0023] The lock cylinder 2 is provided with a ball head 9 and a second lock lug 10 at the end, and the second lock lug 10 is provided with a second lock hole 11;

[0024] In this lock, the lock cylinder 2 is inserted into the ball head lock body 1 through the open end, so that the second lock lug 10 of the lock cylinder 2 protrudes outward from the opening 5. At this time, the first lock hole 8 and the second lock hole 11 correspond to each other. The hockey puck lock 3 locks the lock cylinder 2 and the ball head lock body 1 through the first lock hole 8 and the second lock hole 11. The hockey puck lock 3 is a lock named for its appearance resembling a hockey puck. It is existing technology, and its specific structure will not be described in detail.

[0025] In this embodiment, the adjustable trailer ball cover adaptive locking device is used by first fastening the ball head 9 of the lock cylinder 2 to the ball cover of the RV. After fastening, the ball head lock body 1 is put on the lock cylinder 2. During the insertion process, the lock cylinder 2 moves along the inner wall of the ball head lock body 1. Finally, the second lock lug 10 on the lock cylinder 2 passes through the opening 5 of the end panel 4. At this time, the first lock hole 8 and the second lock hole 11 are aligned. Then, the hockey lock 3 is opened and placed inside the protective cover 6. The hockey lock 3 is used to pass through the first lock hole 8 and the second lock hole 11 to lock the hockey lock 3, thus completing the locking of the ball head lock body 1 and the lock cylinder 2. The protective cover 6 is used to protect the hockey lock 3. A rubber sleeve 15 can also be placed on the outside of the protective cover 6.

[0026] Preferably, in order to prevent the adjustable trailer ball cover adaptive locking device from failing to unlock smoothly due to severe corrosion, the lock cylinder 2 is made of copper and the ball head lock body 1 is made of aluminum alloy.

[0027] The device can also be upgraded. For example, when it rains outdoors, rainwater will accumulate inside the ball lock body 1 and cannot be drained. At this time, several drainage grooves 12 can be opened on the ball lock body 1 to drain the rainwater in time.

[0028] It should be noted that, in this document, terms such as “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
