Description
Technical Field
[0001] This utility model relates to the technical field of plate connection components, specifically a vibration-resistant and anti-loosening type high-strength bolt connection node for stable plates. Background Technology
[0002] In numerous fields such as building construction, bridge construction, and machinery manufacturing, stabilizer plates serve as crucial structural components, undertaking the important tasks of distributing loads and enhancing the overall stability of the structure. The quality of the connections between stabilizer plates directly affects the safety and reliability of the entire structure. High-strength bolt connections are widely used for stabilizer plate connections due to their advantages such as high connection strength and ease of construction.
[0003] However, traditional high-strength bolted connections for stabilized plates are prone to bolt loosening under long-term vibration loads. Vibration gradually reduces the preload between the bolts and the connectors, leading to loosening and affecting structural stability, potentially causing safety accidents. For example, in bridge engineering, vibrations from vehicles causing loosening of the stabilized plate connections can result in localized damage to the bridge structure, threatening traffic safety. Furthermore, existing connection methods are difficult to guarantee in terms of positioning accuracy during installation. Relative positional deviations between stabilized plates can lead to uneven stress distribution, reducing connection quality and affecting the structure's load-bearing capacity. In addition, the connection methods between multiple nodes are not convenient, increasing construction difficulty and time. Therefore, we propose a vibration-resistant and anti-loosening high-strength bolted connection for stabilized plates. Utility Model Content
[0004] The purpose of this utility model is to provide a high-strength bolt connection node for a vibration-resistant and anti-loosening stabilized plate, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a connecting node body, on which a detachable stabilizing plate body is inserted. An mounting plate is fixedly installed on the side wall of the connecting node body, and the mounting plate has a plurality of evenly spaced mounting holes. The stabilizing plate body has a plurality of evenly spaced through holes that mate with the mounting holes. Fastening bolts are inserted through the through holes of the stabilizing plate body and the mounting holes on the mounting plate. Nuts are threaded onto the tops of the fastening bolts. A locking block is fixedly installed on the side wall of the connecting node body. A locking groove that mates with the locking block is formed on the side wall of the stabilizing plate body. An installation cavity is formed inside the locking block. A fixing plate is fixedly installed in the middle of the installation cavity. Telescopic rods are fixedly installed on the upper and lower outer walls of the fixing plate. A sliding plate is fixedly installed at the end of the telescopic arm of the telescopic rod. A limiting rod is fixedly installed on the outer wall of the sliding plate. A limiting groove that mates with the limiting rod is formed on the side wall of the locking groove.
[0006] Preferably, a return spring is sleeved on the outer side of the telescopic rod, one end of the return spring is fixedly connected to the inner wall of the mounting cavity, and the other end of the return spring is fixedly connected to the sliding plate.
[0007] Preferably, positioning plates are symmetrically fixedly installed on the upper and lower sides of the sidewall of the connecting node body, and positioning grooves that cooperate with the positioning plates are opened on the sidewall of the stabilizing plate body.
[0008] Preferably, a groove is provided on one side of the outer wall of the connecting node body, and a slide rail is fixedly installed on the other side of the outer wall of the connecting node body.
[0009] Preferably, the connecting node body also has a threaded hole through it, and a threaded rod is provided inside the threaded hole through a threaded connection.
[0010] Preferably, a groove is provided on the side wall of the connecting node body, and a side plate is fixedly installed on the mounting plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of the card block and the card slot, and the synergistic effect of the telescopic rod, sliding plate, limiting rod and the limiting groove on the side wall of the card slot, the connection quality between the connecting node body and the stabilizing plate body is guaranteed. At the same time, the fastening bolts and nuts further enhance the connection stability between the stabilizing plate bodies, greatly improving the safety of the entire structure in a vibration environment. In addition, the positioning plates symmetrically arranged on the upper and lower sides of the side wall of the connecting node body cooperate with the positioning groove on the side wall of the stabilizing plate body to quickly and accurately determine the installation position of the stabilizing plate body, ensuring uniform distribution of connection stress, improving connection quality, simplifying the installation process, reducing construction difficulty and construction period. The design of the sliding groove on one side of the connecting node body and the sliding rail on the other side facilitates the rapid connection between multiple connecting node bodies. The reinforcement by threaded holes and threaded rods makes the entire connection structure more stable and can better meet the needs of large-scale structure construction.
[0012] In addition, the grooves on the sidewalls of the connecting node body can reduce the exposure of the threaded rods, thereby reducing the risk of them being corroded by the external environment. The side plates on the mounting plate can protect the connection points of the stabilizing plate body, extend the service life of the connecting components, and further ensure the reliability of the structure.

Under the action of the positioning plates 14 and the positioning grooves 15, the connection quality between the connecting node body 2 and the stabilizing plate body 1 is guaranteed, thereby ensuring the connection quality between the stabilizing plate bodies 1.
[0019] A groove 16 is provided on one outer wall of the connecting node body 2, and a slide rail 17 is fixedly installed on the other outer wall of the connecting node body 2.

The groove 20 can reduce the impact of exposed threaded rod 19 on the connection quality. The side plate 22 on the mounting plate 3 can protect the connection of the stabilizing plate body 1. Through the cooperation of components such as the locking block 6 and the locking groove 13, the positioning plate 14 and the positioning groove 15, the fastening bolts 4 and the nuts 5, the slide rail 17 and the slide groove 16, and the threaded rod 19 and the threaded hole 18, the connection quality of the stabilizing plate body 1 is guaranteed in all aspects.
