Description

Technical Field

[0001] This utility model relates to a car wheel locking nut, belonging to the field of tire nut technology. Background Technology

[0002] Car wheel lock nuts, also known as tire nuts, are special nuts used to secure the outer wheel hub of a car. Due to the uncertainty of car nuts, there is no national standard for car nuts. However, the general models are similar to ordinary hexagonal nuts, and there are various models between M12 and M42.

[0003] Currently, the wheel locking nut is connected to the wheel via a connecting sleeve, and the locking screw at the wheel hub is connected to the locking nut to enhance the locking effect. However, the tightening effect of the locking nut connected to the wheel hub in a single direction is limited, which has certain adverse effects on actual use. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a car wheel locking nut. This invention allows for front and rear corresponding fit by setting an upper nut and a lower nut, and enables double screw locking screw connection for inner and outer alignment of the wheel hub. It also adds an adjustable clamping plate to enhance the connection effect of the locking screw and locking nut, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car wheel locking nut, including an upper nut, a lower nut placed below the upper nut, a locking screw placed above the upper nut, a recessed cross groove on the top of the locking screw, an auxiliary plate fixedly connected to the bottom of the lower nut, a fixing plate fixedly connected to the bottom of the inner wall of the auxiliary plate, an internal threaded sleeve fixedly installed inside the fixing plate, an adjusting screw threadedly connected to the inner wall of the internal threaded sleeve, one end of the adjusting screw being rotatably connected to a clamping plate via a bearing, and a limit component connected to the surface of the clamping plate.

[0006] As a further optimization, the overall shape of the locking screw is a double-threaded screw, the diameter of the upper screw is larger than the diameter of the lower screw, and the thread direction on the upper screw is opposite to the thread direction on the lower screw.

[0007] As a further optimization, the top of the upper nut is provided with an arc-shaped surface, and the surface of the arc-shaped surface is coated with a wear-resistant coating.

[0008] As a further optimization, the top of the upper nut is abutted by an anti-slip ring pad, the anti-slip ring pad being made of butadiene rubber.

[0009] As a further optimization, the limiting component includes a limiting plate and a limiting groove. The limiting plate is fixedly connected to the side of the clamping plate, and the limiting groove is formed on the surface of the clamping plate. The inner wall of the limiting groove and the surface of the limiting plate are slidably connected.

[0010] As a further optimization, a magnetic card plate is fixedly connected to the surface of the clamping plate. The surface of the magnetic card plate is provided with an anti-slip texture, and the number of magnetic card plates is at least two.

[0011] As a further optimization, a positioning magnetic plate is fixedly connected to the top of the lower nut, and the overall shape of the positioning magnetic plate is arc-shaped.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The locking screw can enter the interior of the upper and lower nuts. Since the locking screw is divided into an upper screw and a lower screw, it can be adapted to different upper and lower nuts according to different screw sizes. Since the threads on the upper screw and the lower screw are opposite, it avoids the situation of stripping the locking screw during use. It can achieve the connection and locking effect of two locking nuts and locking screws used separately.

[0014] 2. An adjustable clamping plate is located inside the additional plate. Rotating the adjusting screw moves the clamping plate, which is then guided by a limiting component. When the clamping plate reaches the opening of the lower nut, a magnetic clamping plate further enhances the locking effect of the locking screw. If the lower nut is abutting at the adjustable point, the adjusting screw can be rotated again to adjust the tightness of the clamping plate, thus strengthening the connection between the lower nut and the locking screw.

Detailed Implementation

[0021] 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.

[0022] Example 1

[0023] Please see Figures 1 to 4 As shown, a car wheel locking nut includes an upper nut 1, a lower nut 2 placed below the upper nut 1, a locking screw 3 placed above the upper nut 1, a recessed cross groove 4 on the top of the locking screw 3, an auxiliary plate 5 fixedly connected to the bottom of the lower nut 2, a fixing plate 6 fixedly connected to the bottom of the inner wall of the auxiliary plate 5, an internal threaded sleeve 7 fixedly installed inside the fixing plate 6, an adjusting screw 8 threadedly connected to the inner wall of the internal threaded sleeve 7, and a clamping plate 9 rotatably connected to one end of the adjusting screw 8 via a bearing, with a limit component connected to the surface of the clamping plate 9.

[0024] Specifically, the locking screw 3 has a double-threaded screw shape. The diameter of the upper screw is larger than that of the lower screw, and the thread direction on the upper screw is opposite to that on the lower screw. Since the locking screw 3 is divided into an upper screw and a lower screw, different upper nuts 1 and lower nuts 2 can be used to accommodate different screw sizes. Furthermore, because the thread directions on the upper screw and the lower screw are opposite, the locking screw 3 is protected from stripping during use.

[0025] Furthermore, the limiting component includes a limiting plate 12 and a limiting groove 13. The limiting plate 12 is fixedly connected to the side of the clamping plate 9, and the limiting groove 13 is formed on the surface of the fixing plate 6. The inner wall of the limiting groove 13 is slidably connected to the surface of the limiting plate 12. By setting the limiting plate 12 and the limiting groove 13, the movement trajectory of the clamping plate 9 is limited, so that the adjusting screw 8 and the clamping plate 9 move under the guidance of rotation.

[0026] Specifically, the top of the upper nut 1 has an arc-shaped surface 10, and the surface of the arc-shaped surface 10 is coated with a wear-resistant coating. The top of the upper nut 1 abuts against an anti-slip ring pad 11, which is made of butadiene rubber. The anti-slip ring pad 11 allows the locking screw 3, which is rotated by the pressure thread, to enter the upper nut 1 and is recessed in the arc-shaped surface 10 to receive the recessed anti-slip ring pad 11.

[0027] Example 2

[0028] Please see Figures 1 to 4 As shown, the difference between this embodiment and Embodiment 1 is that: a magnetic suction plate 14 is fixedly connected to the surface of the clamping plate 9. The surface of the magnetic suction plate 14 has an anti-slip texture, and there are at least two magnetic suction plates 14, which enhance the locking effect of the locking screw 3. A positioning magnetic suction plate 15 is fixedly connected to the top of the lower nut 2. The overall shape of the positioning magnetic suction plate 15 is arc-shaped. The positioning magnetic suction plate 15 is used for magnetic positioning, which facilitates the magnetic positioning of the lower nut 2 at the installation position or the connection of the upper nut 1.

[0029] The working principle of this utility model is as follows: In use, an upper nut 1 and a lower nut 2 are provided at the wheel hub. Depending on the surface of different wheel hubs, the upper nut 1 and lower nut 2 can be fitted together front to back or the two upper and lower nuts 2 can be used in abutting position. Then, the locking screw 3 can be rotated into the upper nut 1 and lower nut 2. Because the locking screw 3 consists of an upper screw and a lower screw, different sizes of screws can be used to accommodate different upper nuts 1 and lower nuts 2. Furthermore, because the threads on the upper and lower screws are in opposite directions, stripping of the locking screw 3 during use is avoided. The clamping plate 9 is adjusted to hold the extended locking screw 3, i.e., the operation of the rotating adjusting screw 8... The clamping plate 9 moves due to the movement of the clamping plate. The movement trajectory of the clamping plate 9 is limited by the setting of the limiting plate 12 and the limiting groove 13, so that the clamping plate 9 moves under the rotational guidance between the adjusting screw 8 and the clamping plate 9. When the clamping plate 9 moves to the diameter of the lower nut 2, the magnetic suction plate 14 is added to strengthen the locking effect of the locking screw 3. If the lower nut 2 abuts against the adjustable position, the adjusting screw 8 can be rotated again to adjust the movement and tightening degree of the clamping plate 9. The positioning magnetic suction plate 15 is used for magnetic positioning, which can facilitate the magnetic positioning of the lower nut 2 at the installation position or the connection of the upper nut 1. It can realize the locking nut installation connection effect according to the interlayer mounting surface of different wheel hubs.

[0030] 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.
