Technical Field

[0001] This utility model relates to the field of mechanical fastening device technology, specifically a double-eared multi-functional high-lock nut. Background Technology

[0002] With the increasing demands for connection reliability in fields such as aerospace, rail transportation, and high-end equipment manufacturing, traditional nuts are prone to loosening and fatigue failure under complex working conditions, making it imperative to have fastening devices with adaptive adjustment and vibration resistance capabilities.

[0003] Traditional nuts are prone to slider misalignment and bolt head deformation under high load or vibration environments, which affects the normal use of the device and thus its service life. Utility Model Content

[0004] The purpose of this utility model is to provide a double-eared multi-functional high-lock nut to solve the problem that traditional nuts are prone to slider displacement and bolt head deformation under high load or vibration environments, which will affect the normal use of the device and thus affect the service life of the device in the long run.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a double-eared, multi-functional high-lock nut, comprising a screw, a bolt head, a friction ring, and a connecting rod. One end of the connecting rod is fixedly connected to the bolt head. The surface of the connecting rod is provided with the screw, and the surface of the screw is slidably connected to the friction ring. The inner wall of the screw has an installation structure, which includes a connecting plate. The surface of the connecting plate is fixedly connected to the inner wall of the screw, and the surface of the connecting plate has a groove. A slider is slidably connected to the inner wall of the groove. A connecting block is fixedly connected to the surface of the screw, and the surface of the slider is fixedly connected to the surface of the connecting rod. The connecting block is fixed to the surface of the screw and slidably connected to the inner wall of the bolt head groove, participating in the connection and fixing of the nut with other components. The connecting plate is fixed to the inner wall of the screw, providing an installation base for the groove and guide block, serving a supporting and positioning function. The groove and slider allow the slider to slide within the groove. By being fixedly connected to the connecting rod, the position of the connecting rod can be adjusted within a certain range, thereby changing the installation state and tightness of the nut.

[0007] Furthermore, a fixing rod is fixedly connected to the inner wall of the slide groove, and the arc surface of the fixing rod is slidably connected to the surface of the slider. The fixing rod is fixed to the inner wall of the slide groove, passes through the slider, ensures the stability and accuracy of the slider's sliding, and prevents the slider from deviating from the track during the sliding process.

[0008] Furthermore, a guide block is fixedly connected to the surface of the connecting plate, and the guide block has a triangular cross-section. The triangular cross-section of the guide block serves as a guide during installation, facilitating the installation and positioning of other components.

[0009] Furthermore, the surface of the bolt head is provided with a groove, and a sliding rod is slidably connected to the inner wall of the groove. The surface of the connecting block is slidably connected to the inner wall of the groove. The sliding rod enables sliding within the bolt head groove, providing a track for the installation and sliding of the square block and the spring.

[0010] Furthermore, a stop block is fixedly connected to one end of the slide rod, and a square block is slidably connected to the arc surface of the slide rod. The square block allows it to slide on the slide rod and can cooperate with other components to achieve certain positioning and fixing functions. The stop block is fixed to one end of the slide rod, limiting the sliding range of the square block and preventing it from sliding off the slide rod.

[0011] Furthermore, a spring is fitted onto the arc surface of the slide rod. One end of the spring is fixedly connected to the surface of the stop block, and the other end of the spring is fixedly connected to the surface of the square block. The spring, fitted onto the arc surface of the slide rod and fixedly connected at both ends to the stop block and the square block respectively, provides buffering and reset functions through elasticity, ensuring the stability and reliability of the nut during installation and use.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a sliding mechanism between a groove and a slider to dynamically adjust the pressure between the friction ring and the connecting rod, ensuring stable tightening of the nut under various operating conditions. The groove is fixed to the connecting plate, and the slider is embedded in the groove and fixedly connected to the connecting rod, forming a sliding pair. When the connecting rod is subjected to external force, the slider slides along the groove trajectory. The sliding of the slider directly drives the connecting rod to move axially along the screw. Since the friction ring is fitted onto the screw surface, its relative position to the connecting rod changes accordingly. The axial displacement of the connecting rod causes dynamic changes in the pressure at the contact surface between the friction ring and the connecting rod, adapting to different load requirements. This ensures adjustable tightening force while preventing loosening or damage due to insufficient or excessive pressure.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
