Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically a high-tightening-force automotive spring nut. Background Technology

[0002] A leaf nut is a type of nut similar to a spring, composed of multiple flat thin plates. It possesses a certain degree of elasticity and resilience, ensuring that the connection remains secure and adaptable to connections of different shapes and sizes. It is commonly used in high-strength and high-vibration applications, such as machinery, automobiles, aircraft, and ships.

[0003] According to patent authorization announcement number CN214578233U, a corrosion-resistant automotive spring nut includes a spring, an anti-corrosion mechanism, an installation mechanism, and a fixing mechanism. Velcro is attached to both sides of the inner wall of the spring, and an anti-slip pad is attached to one side of the Velcro. The anti-corrosion mechanism is installed on the outer wall of the spring, and the installation mechanism is installed on one side of the spring, with a threaded sleeve installed on one side. This corrosion-resistant automotive spring nut, by incorporating a first movable block, a first movable hook, and an epoxy resin layer, allows the epoxy resin layer to be pushed, causing the first movable hook to be fixedly connected to the first movable block. This secures the epoxy resin layer to the outer wall of the spring, facilitating surface corrosion protection and preventing corrosion caused by prolonged use inside the vehicle and liquid contamination, thus effectively improving the device's performance.

[0004] However, in existing automotive spring nuts, the spring is usually limited by pressing down on the spring with a baffle to achieve the effect of limiting and fixing the spring. However, because the spring has elasticity, it is easy for the spring to bend and deform and detach from the lower end of the baffle, or the baffle may not be stable when pressed down, which brings a lot of inconvenience to use. At the same time, the nuts are mostly installed by threads, but threaded connections are prone to loosening and detachment after long-term use. Utility Model Content

[0005] The purpose of this invention is to provide a high-tightening-force automotive spring nut that solves the problems of limiting the stability of the spring and limiting the installation of the nut.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-tightening-force automotive spring nut, comprising a cover plate, the cover plate having a threaded hole, an inner ring fixedly connected to the lower end of the cover plate, an outer ring fixedly connected to the lower end of the cover plate, the connection between the inner ring and the outer ring being configured as an annular groove, a rubber ring being slidably connected inside the inner ring, and a vertical block fixedly connected to the upper end of the cover plate.

[0007] Preferably, the inner ring is disposed inside the outer ring, and the inner ring and the outer ring have the same height.

[0008] Preferably, the rubber ring is disposed at the lower end of the cover plate, and the inner diameter of the rubber ring is the same as the inner diameter of the threaded hole.

[0009] Preferably, the outer side of the stand block is provided with an outer hexagonal edge, the stand block has a through groove, the inner side of the stand block is provided with an inner hexagonal edge, and the inner hexagonal edge is located inside the through groove.

[0010] Preferably, the support block is disposed at the upper end of the inner ring and the outer ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model connects the inner ring and the outer ring at the lower end of the cover plate. The inner ring limits the inner side of the upper end of the spring, and the outer ring limits the outer side of the upper end of the spring, thereby preventing the upper end of the spring from tilting inward or outward, thus preventing the upper end of the spring from detaching from the lower end of the cover plate, and preventing the spring from deviating and bending.

[0013] 2. This utility model uses a rubber ring to snap onto the inner side of the inner ring. The rubber ring is located at the lower end of the threaded hole, so that when the threaded hole rotates and connects to the surface of the connecting object, the rubber ring is also sealed and fitted onto the surface of the connecting object, increasing tightness and friction, and reducing the chance of the threaded hole connection falling off.
