Description

Technical Field

[0001] This application relates to the field of gooseneck balls, and more particularly to an anti-tilting 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 the vehicle during use so that the RV, trailer, and yacht can move.

[0003] Generally speaking, a gooseneck ball consists of a ball and a mounting body. The gooseneck ball is fixedly connected to the mounting body at the rear of the vehicle via a mounting seat at the rear of the vehicle. A trailer ball cover is installed at the front of the RV, trailer, or yacht. The trailer ball cover can press and fix the ball of the gooseneck ball inside the trailer ball cover to complete the trailer connection between the RV, trailer, yacht, and the vehicle.

[0004] Regarding the aforementioned technologies, existing gooseneck ball joints are prone to tilting at the connection between the ball and the coupler during towing, which can easily lead to traffic accidents during towing. Summary of the Invention

[0005] In order to make the connection between the sphere and the coupler more stable and less prone to tilting, this application provides an anti-tilting gooseneck ball.

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

[0007] An anti-tilt gooseneck ball includes a ball for connection to a trailer ball cover;

[0008] The mounting body is fixedly connected to the sphere and is used to connect to the mounting base;

[0009] And an anti-tilt body, wherein the anti-tilt body is sleeved on the outer circumferential surface of the sphere, and when the sphere passes through the coupler and is connected to the coupler, one side of the anti-tilt body abuts against the coupler, and the other side of the anti-tilt body abuts against the sphere.

[0010] By adopting the above technical solution, when it is necessary to make the connection between the sphere and the coupler of the gooseneck ball more stable and less prone to tilting, the mounting body is installed on the mounting seat at the rear of the vehicle, the anti-tilt body is sleeved on the outer circumference of the sphere, and one side of the anti-tilt body abuts against the sphere, connecting the sphere to the coupler. At the same time, while one side of the anti-tilt body abuts against the sphere, the other side of the anti-tilt body abuts against the coupler, so that the anti-tilt body fills the space between the coupler and the sphere, thereby limiting the swing between the sphere and the coupler, making it less likely for the sphere to swing relative to the coupler, and making it less likely for the sphere to tilt. This improves the problem that the connection between the sphere and the coupler of the existing gooseneck ball is prone to tilting during towing, which can easily lead to traffic accidents during towing.

[0011] Optionally, the anti-tilt body is a cushioning pad.

[0012] Optionally, the gasket material includes polyurethane.

[0013] Optionally, the sphere includes a ball portion, and the anti-tilt body abuts against the ball portion.

[0014] Optionally, the sphere includes a spherical part and a reinforcing part, the reinforcing part being connected to the outer peripheral surface of the spherical part, and the anti-tilt body abutting against the reinforcing part.

[0015] Optionally, the reinforcing part includes a reinforcing top plate, which is connected to the ball part, and the anti-tilting body abuts against the reinforcing top plate.

[0016] Optionally, the reinforcing part may further include at least one reinforcing rib, each of the reinforcing ribs being fixedly disposed on the ball portion and extending to the mounting body, and each of the reinforcing ribs being connected to the reinforcing top piece.

[0017] Optionally, the reinforcing part may further include a reinforcing base plate located between the mounting body and the reinforcing rib, the reinforcing base plate being connected to the ball portion, and one side of the reinforcing base plate being connected to the reinforcing rib.

[0018] Optionally, the reinforcing portion may further include one or more reinforcing plates, which are connected to the ball portion;

[0019] Furthermore, the reinforcing sheet and each of the reinforcing ribs are fixedly connected.

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

[0021] When a more stable connection between the gooseneck ball and the coupler is required, preventing tilting, the mounting body is installed on the mounting bracket at the rear of the vehicle. The anti-tilt body is fitted onto the outer circumference of the ball, with one side of the anti-tilt body abutting against the ball. The ball is then connected to the coupler, and while one side of the anti-tilt body abuts against the ball, the other side abuts against the coupler. This anti-tilt body fills the space between the coupler and the ball, limiting the swing between the ball and the coupler. This prevents the ball from swinging relative to the coupler and tilting, thus improving the problem of existing gooseneck balls easily tilting during towing, which can lead to traffic accidents.

[0054] The following is in conjunction with the appendix Figure 1-22 This application will be described in further detail.

[0055] This application discloses an anti-tilting gooseneck ball.

[0056] Example 1.

[0057] Reference Figures 1 to 5 An anti-tilt gooseneck ball includes a ball 10, a mounting body 20, and an anti-tilt body 30. The ball 10 is used to connect with a trailer ball cover. The mounting body 20 is fixedly connected to the ball 10 and used to connect with a mounting base. The anti-tilt body 30 is sleeved on the outer circumferential surface of the ball 10. When the ball 10 passes through a coupler and is connected to the coupler, one side of the anti-tilt body 30 abuts against the coupler, and the other side of the anti-tilt body 30 abuts against the ball 10. The axes of the ball 10 and the mounting body 20 do not coincide.

[0058] The sphere 10 includes a spherical part 1 and a reinforcing part 3. The spherical part 1 includes a spherical segment 11, an arc segment 12, and a cylindrical segment 13. The spherical segment 11, the arc segment 12, and the cylindrical segment 13 are fixedly connected in sequence. The spherical segment 11 is spherical. The diameter of the arc segment 12 gradually decreases from the end near the cylindrical segment 13 to the end near the spherical segment 11. The cylindrical segment 13 is cylindrical.

[0059] The reinforcing part 3 includes two reinforcing ribs 31, a reinforcing top piece 32, and a reinforcing connecting piece 33. The two reinforcing pieces 31 are fixedly disposed on the outer circumferential surface of the cylindrical section 13 and extend along the connecting section 21. The two reinforcing ribs 31 are arranged parallel to each other. The reinforcing top piece 32 is located on the top of the two reinforcing ribs 31. The reinforcing top piece 32 is fixedly disposed on the outer circumferential surface of the cylindrical section 13, and one side of the reinforcing top piece 32 is fixedly connected to both reinforcing ribs 31.

Both connecting holes 221 are connected to the central hole 222.

[0061] In this embodiment, the anti-tilt body 30 is a cushioning pad, and the pad material includes polyurethane.

[0062] The implementation principle of Embodiment 1 is as follows: When it is necessary to make the connection between the ball 10 of the gooseneck ball and the coupler more stable and less prone to tilting, the mounting body 20 is installed on the mounting seat at the rear of the vehicle, and the anti-tilt body 30 is fitted onto the outer circumference of the ball 10, with one side of the anti-tilt body 30 abutting against the ball 10. The ball 10 is connected to the coupler, and while one side of the anti-tilt body 30 abuts against the ball 10, the other side of the anti-tilt body 30 abuts against the coupler, so that the anti-tilt body 30 fills the space between the coupler and the ball 10, thereby limiting the swing between the ball 10 and the coupler, making it less likely for the ball 10 to swing relative to the coupler, and making it less prone to tilting. This improves the problem that the connection between the ball 10 and the coupler of the existing gooseneck ball is prone to tilting during towing, which can easily lead to traffic accidents during towing.
