Description

Technical Field

[0001] This application relates to the field of gooseneck balls, and more particularly to an anti-theft gooseneck ball. Background Technology

[0002] Currently, more and more users in the domestic market are starting to use and engage in outdoor sports, including products such as RVs, trailers, and yachts. These large products require a trailer connection with a car during use so that they can move. Generally, this is achieved by installing a gooseneck ball at the rear of the car and a trailer ball cover at the front of the RV, trailer, or yacht. The trailer ball cover can press and fix the trailer ball part of the gooseneck ball inside the trailer ball cover to complete the trailer connection between the RV, trailer, or yacht and the car.

[0003] Currently, most cars on the market do not come with a gooseneck ball joint at the rear when they leave the factory; users need to install it themselves. This is typically done by installing a ball hook mount at the rear of the car, and then attaching the gooseneck ball to the mount. This allows for the replacement of different gooseneck ball models as needed. Currently, the gooseneck ball and the ball hook mount are connected by threads; that is, the gooseneck ball has external threads, and the ball hook mount has internal threads. The gooseneck ball is screwed onto the ball hook mount.

[0004] Regarding the aforementioned technologies, the simple screwing of the gooseneck ball onto the ball hook mounting base poses a risk of theft. Summary of the Invention

[0005] To reduce the risk of gooseneck ball being stolen, this application provides an anti-theft gooseneck ball.

[0006] The anti-theft gooseneck ball provided in this application adopts the following technical solution:

[0007] An anti-theft gooseneck ball includes a shell, one end of which is inserted into a ball hook mounting base;

[0008] A locking assembly is disposed in a housing. The locking assembly includes multiple snap-fit ​​members and a lock cylinder. The housing has multiple snap-fit ​​holes. Each snap-fit ​​member passes through and slides into each snap-fit ​​hole. The lock cylinder slides into the housing.

[0009] When the lock cylinder slides towards the housing and locks, each of the locking components is locked in place by locking with the ball hook mounting base.

[0010] By adopting the above technical solution, when the gooseneck ball is installed on the ball hook mounting seat, one end of the housing passes through the ball hook mounting seat, and each snap-fit ​​component slides away from the center of the housing along its respective snap-fit ​​hole until each snap-fit ​​component is snapped and fixed to the ball hook mounting seat. Then, the locking component locks, thereby fixing the locking component to the housing. This ensures that each snap-fit ​​component remains snapped and fixed to the ball hook mounting seat. At the same time, the locking component locks and is fixed to the housing, making it difficult to remove the gooseneck ball from the ball hook mounting seat when the locking component is not unlocked. This reduces the risk of the gooseneck ball being stolen and improves the problem of the risk of theft that arises from simply screwing the gooseneck ball onto the ball hook mounting seat.

[0011] Optionally, the locking assembly further includes a locking rod, which passes through and slides into the housing, and is fixedly connected to the lock cylinder. The locking rod includes a snap-fit ​​section, a conical section, and a cylindrical section, which are connected in sequence. When the cylindrical section abuts against each of the snap-fit ​​pieces, the locking assembly unlocks. The locking rod slides, and when it slides from the cylindrical section to the snap-fit ​​section, it pushes each snap-fit ​​piece to snap into place with the ball hook mounting base.

[0012] Optionally, the locking assembly further includes a lock cylinder, which is slidably fitted into the housing and fixedly connected to the locking rod;

[0013] A locking block is slidably engaged with a lock cylinder. The housing has a locking groove. When the locking assembly is locked to be fixed with the housing, the lock cylinder slides towards the housing until it abuts against the housing. The lock cylinder is driven to push the locking block through and engage with the locking groove.

[0014] Optionally, the lock cylinder is rotatably connected to a lock cover, which is used to cover the lock hole of the lock cylinder.

[0015] Optionally, the locking assembly further includes a return spring located between the locking rod and the housing, with one end of the return spring abutting against the locking rod and the other end of the return spring abutting against the housing.

[0016] Optionally, a base plate is connected to one end of the housing. The base plate can be detached from the housing. When the base plate is detached from the housing, the return spring can be detached from the housing.

[0017] Optionally, the snap-fit ​​shape may include a sphere.

[0018] Optionally, the diameter of the snap-fit ​​hole gradually decreases from the center of the housing to the outer side of the housing.

[0019] Optionally, the snap-fit ​​component includes three components, each of which is evenly distributed circumferentially around the axis of the housing.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] When the gooseneck ball is installed on the ball hook mounting base, one end of the housing passes through the ball hook mounting base. Each snap-fit ​​component slides away from the center of the housing along its respective snap-fit ​​hole until all snap-fit ​​components are snapped and fixed to the ball hook mounting base. Then, the locking component locks, thus fixing the locking component to the housing. This ensures that each snap-fit ​​component remains snapped and fixed to the ball hook mounting base. At the same time, the locking component is locked and fixed to the housing, making it difficult to remove the gooseneck ball from the ball hook mounting base when the locking component is not unlocked. This reduces the risk of the gooseneck ball being stolen and improves the problem of the risk of theft that arises from simply screwing the gooseneck ball onto the ball hook mounting base.

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0039] This application discloses an anti-theft gooseneck ball. (See attached embodiment.) Figure 1 and Figure 2 An anti-theft gooseneck ball includes a housing 1 and a locking component 2, wherein the locking component 2 is disposed on the housing 1 and is used to fix the housing 1 to the ball hook mounting base.

[0040] Reference Figure 3 The housing 1 includes a spherical part 11, a trailer part 12, a main body part 13, and a mounting part 14. The spherical part 11, the trailer part 12, the main body part 13, and the mounting part 14 are sequentially fixedly connected to each other. The trailer part 12 has a circular cross-section. The diameter of the trailer part 12 gradually increases from the main body part 13 to the spherical part 11. The diameter of the spherical part 11 gradually increases away from the trailer part 12 until it reaches the diameter of the spherical part 11, so as to achieve a smooth transition between the main body part 13 and the spherical part 11, and at the same time, make the trailer rope more stably connected to the trailer part 12. The main body part 13 and the mounting part 14 are both cylindrical. The diameter of the main body part 13 is larger than the diameter of the mounting part 14. When the housing 1 is inserted into the ball hook mounting seat, the mounting part 14 is inserted into the ball hook mounting seat, and the main body part 13 abuts against the ball hook mounting seat.

[0041] Reference Figure 4 and Figure 5The housing 1 has a locking hole 100 at one end. The locking hole 100 includes a first hole segment 101, a second hole segment 102, and a third hole segment 103. The first hole segment 101, the second hole segment 102, and the third hole segment 103 are connected in sequence. The diameter of the first hole segment 101, the second hole segment 102, and the third hole segment 103 gradually increases. A base plate 15 is connected to one end of the housing 1. The base plate 15 is fixedly connected to the housing 1 by multiple screws, so that the base plate 15 can be disassembled from the housing 1. When the base plate 15 is connected to the housing 1, the locking hole 100 is closed by the base plate 15.

[0042] Reference Figure 6 The locking component 2 includes three snap-fit ​​pieces 21. In this embodiment, each snap-fit ​​piece 21 is a sphere. The mounting part 14 has three through-hole snap-fit ​​holes 200. Each snap-fit ​​hole 200 is evenly distributed around the axis of the mounting part 14. Each snap-fit ​​piece 21 passes through and slides into each snap-fit ​​hole 200. The diameter of each snap-fit ​​hole 200 gradually decreases from the center of the housing 1 to the outside of the housing 1, so that when each snap-fit ​​piece 21 passes through each snap-fit ​​hole 200, it is not easy to detach from the end of each snap-fit ​​hole 200 away from the housing 1. When the mounting part 14 is fixedly connected to the ball hook mounting seat, each snap-fit ​​piece 21 is snapped and fixed to the ball hook mounting seat.

[0043] Reference Figure 7 and Figure 8 The locking assembly 2 also includes a locking rod 22, which passes through and slides into the locking hole 100. The locking rod 22 includes a rod body section 221, a snap-fit ​​section 222, a conical section 223, a cylindrical section 224, and a bottom section 225. The rod body section 221, snap-fit ​​section 222, conical section 223, cylindrical section 224, and bottom section 225 are sequentially fixedly connected. The snap-fit ​​section 222, conical section 223, cylindrical section 224, and bottom section 225 are all located in the third hole section 103. When component 2 is unlocked, cylindrical section 224 abuts against each locking member 21. When locking rod 22 slides away from housing 1 along locking hole 100, the abutting engagement between locking member 21 and locking rod 22 changes from cylindrical section 224 to conical section 223. Each locking member 21 is pushed by conical section 223 to slide away from housing 1 along locking hole 200 until each locking member 21 abuts against locking section 222. At this time, each locking member 21 is locked and fixed to ball hook mounting seat.

[0044] Reference Figure 7 and Figure 8The locking assembly 2 also includes a return spring 23, which is located in the third hole section 103 and between the bottom plate 15 and the bottom section 225. One end of the return spring 23 abuts against the bottom plate 15, and the other end of the return spring 23 abuts against the bottom section 225. When the locking assembly 2 is unlocked, the return spring 23 pushes the locking rod 22 to slide quickly along the locking hole 100 toward the housing 1 until the locking section 222 abuts against the hole wall of the third hole section 103. In addition, when the bottom plate 15 is removed from the bottom of the housing 1, the return spring 23 can be disengaged from the third hole section 103, thereby realizing the installation and replacement of the return spring 23.

[0045] Reference Figure 9 The locking assembly 2 also includes a lock cylinder 24 and a locking block 25. The ball part 11 has a fixing groove 300 at the end away from the trailer part 12. The lock cylinder 24 passes through and slides into the fixing groove 300. The lock cylinder 24 is fixedly connected to the rod section 221 of the locking rod 22. When the lock cylinder 24 slides along the fixing groove 300 toward the direction closer to the housing 1, it drives the locking rod 22 to slide along the locking hole 100 toward the direction away from the housing 1, thereby pushing each snap-fit ​​part 21 to slide away from the housing 1, so that each snap-fit ​​part 21 is snapped and fixed with the ball hook mounting seat.

[0046] The locking block 25 slides and engages with the lock cylinder 24. When the key is inserted into the lock hole of the lock cylinder 24 and drives the lock cylinder 24, the locking block 25 slides away from the lock cylinder 24. The fixing groove 300 has a locking groove 301. When the lock cylinder 24 slides along the fixing groove 300 towards the housing 1 until the lock cylinder 24 abuts against the bottom of the fixing groove 300, the locking component 2 locks. When the key is inserted into the lock hole of the lock cylinder 24 and rotated, the locking block 25 slides towards the lock cylinder 24, thereby disengaging from the locking groove 301. The locking component 2 unlocks. The lock cylinder 24 is rotatably connected to the lock cover 241, which is used to cover the lock hole of the lock cylinder 24.

[0047] The implementation principle of the anti-theft gooseneck ball in this application embodiment is as follows: When the gooseneck ball is installed on the ball hook mounting seat, one end of the housing 1 passes through the ball hook mounting seat. Each snap-fit ​​component 21 slides along each snap-fit ​​hole 200 in a direction away from the center of the housing 1 until each snap-fit ​​component 21 is snapped and fixed with the ball hook mounting seat. Then, the locking component 2 locks, thereby fixing the locking component 2 to the housing 1. This ensures that each snap-fit ​​component 21 is always snapped and fixed with the ball hook mounting seat. At the same time, the locking component 2 is locked and fixed to the housing 1, so that the gooseneck ball is not easy to remove from the ball hook mounting seat when the locking component 2 is not unlocked. This reduces the risk of the gooseneck ball being stolen and improves the problem of the risk of theft that arises from simply screwing the gooseneck ball onto the ball hook mounting seat.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
