Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to an anti-loosening locking connector for steel structure nodes. Background Technology

[0002] Steel structures are modern building systems that use steel as the main load-bearing component and are connected by welding or bolting. Their core advantages are high strength, light weight, fast construction speed, the ability to build large-span and super high-rise buildings, and the fact that the materials are recyclable and environmentally friendly.

[0003] However, in existing technologies, traditional connection methods, such as bolting and welding, although they can provide initial stability, can loosen over time and with changes in environmental factors. This loosening is especially pronounced in high-load or frequently vibrating environments, leading to structural instability and increasing maintenance and safety hazards. Secondly, human error is a significant factor. Traditional connection methods typically rely on manual assembly, requiring operators to possess advanced skills and precise operation. However, in high-intensity working environments, human error is unavoidable. Even minor mistakes can result in weak connections, thereby affecting the stability and safety of the entire structure. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the connection parts will loosen over time and with changes in environmental factors, especially in high-load or frequent vibration environments, which leads to structural instability. Therefore, this invention proposes an anti-loosening locking connector for steel structure nodes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel structure node anti-loosening locking connector, comprising two steel structure plates, a connecting mechanism installed in a through hole in the center of the two steel structure plates, and a limit ring sleeved on the outer surface of one end of the connecting mechanism;

[0006] The connecting mechanism includes a handle, a threaded sleeve fixedly connected to one end of the handle, a connecting sleeve fixedly connected to one end of the threaded sleeve, a slide rod provided inside the connecting sleeve, a sliding frame slidably connected to the outer surface of one end of the slide rod, rotating blocks rotatably connected to both sides of the sliding frame, movable grooves opened on both sides of the connecting sleeve, the rotating blocks movably installed inside the movable grooves, and a spring provided inside the connecting sleeve, one end of the spring abutting against the inner wall of the connecting sleeve, and the other end of the spring abutting against the sliding frame.

[0007] Preferably, one end of the slide rod is fixedly connected to the inner wall of the connecting sleeve, and the other end of the slide rod is fixedly connected to an installation rod.

[0008] Preferably, the outer surface of the threaded sleeve is threaded with a locking sleeve, which abuts against the side wall of one of the steel structure plates.

[0009] Preferably, multiple threaded rods are installed on the outer surface of the limiting ring, and the threaded rods pass through the limiting ring and are threadedly connected to another steel structure plate.

[0010] Preferably, a limiting sleeve is fixedly connected to the inner wall of the limiting ring, and the limiting sleeve is sleeved on the outer surface of the connecting sleeve.

[0011] Preferably, a limiting groove is formed on the inner wall of the limiting sleeve.

[0012] Preferably, the limiting groove is engaged with the rotating block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, one end of the connecting sleeve is first passed through two steel structure plates. The elasticity of the spring pushes the sliding frame to slide along the surface of the sliding rod. The sliding frame drives the rotating block to move. Under the limiting action of the movable groove, the rotating block starts to rotate and moves out of the groove to unfold. The displacement of the connecting sleeve is prevented. Then, by rotating the locking sleeve, it moves along the surface of the threaded sleeve until one end of the locking sleeve abuts against the side wall of the steel structure plate. The locking sleeve and the rotating block cooperate to lock the connection and prevent loosening. The stability of the connection is achieved by the cooperation of the spring, the sliding frame and the rotating block. This design can ensure the tight connection of the steel structure plates and prevent loosening during use.

[0015] 2. In this utility model, a limiting sleeve is fitted onto the outer surface of the connecting sleeve to protect the rotating block and prevent external forces from affecting it. One end of the rotating block is tightly abutted against the steel structure plate. Combined with the synergistic effect of the locking sleeve, it is ensured that the rotating block cannot move freely. The design of the limiting sleeve and the limiting groove further improves the stability of the rotating block. The limiting sleeve effectively prevents external impacts from affecting the rotating block, while the limiting groove restricts the movement trajectory of the rotating block to ensure that it is always in the correct position, avoiding structural damage or connection failure caused by improper displacement. Through this dual protection, the anti-interference ability and reliability of the entire connection system are enhanced. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-3 As shown, this utility model provides an anti-loosening locking connector for steel structure nodes, including two steel structure plates 1, with a through hole in the center of the two steel structure plates 1 for installing a connecting mechanism 3, and a limit ring 2 sleeved on the outer surface of one end of the connecting mechanism 3.

[0024] The connecting mechanism 3 includes a handle 31, one end of which is fixedly connected to a threaded sleeve 34, and the other end of which is fixedly connected to a connecting sleeve 35. A slide rod 37 is provided inside the connecting sleeve 35, and a sliding frame 39 is slidably connected to the outer surface of one end of the slide rod 37. Rotating blocks 36 are rotatably connected to both sides of the sliding frame 39. Movable grooves 351 are provided on both sides of the connecting sleeve 35. The rotating blocks 36 are movably installed inside the movable grooves 351. A spring 38 is provided inside the connecting sleeve 35. One end of the spring 38 abuts against the inner wall of the connecting sleeve 35, and the other end of the spring 38 abuts against the sliding frame 39.

[0025] The specific setup and function of this embodiment are described below. When connecting two steel structure plates 1, one end of the connecting sleeve 35 needs to be passed through these two steel structure plates 1. At this time, the spring 38 inside the connecting sleeve 35 plays a role, and with its elasticity, it pushes the sliding frame 39 to slide along the outer surface of the sliding rod 37. During the sliding process, the sliding frame 39 can drive the two rotating blocks 36 to undergo relative displacement. Since the rotating blocks 36 are designed in the movable groove 351, when the sliding frame 39 moves, the rotating blocks 36 will be limited by the edge of the movable groove 351 and begin to rotate along the groove. At this time, the two rotating blocks 36 gradually disengage from the movable groove 351 and unfold outward.

[0026] As the rotating block 36 unfolds, one end of the connecting sleeve 35 is fixed between the steel structure plates 1, preventing further displacement of the sleeve. At this point, the locking step begins. Specifically, the locking sleeve 33 is rotated, moving along the thread direction on the outer surface of the threaded sleeve 34 until one end of the locking sleeve 33 abuts against the side wall of one of the steel structure plates 1. At this point, the locking sleeve 33 and the rotating block 36 cooperate, ensuring the stability of the connection through rotation.

[0027] After locking, the position of the rotating block 36 in the movable groove 351 is firmly locked, effectively preventing the connection between the two steel structure plates 1 from loosening. This structure design utilizes the principle of the spring 38 pushing the sliding frame 39 and the rotating block 36 to unfold, achieving reliable fixing of the connecting sleeve 35 and tight connection between it and the steel structure plate 1, avoiding potential loosening problems during use.

[0028] Example 2: Figure 3 and Figure 4 As shown, one end of the slide rod 37 is fixedly connected to the inner wall of the connecting sleeve 35, and the other end of the slide rod 37 is fixedly connected to the mounting rod 32. A locking sleeve 33 is threadedly connected to the outer surface of the threaded sleeve 34, and the locking sleeve 33 abuts against the side wall of one of the steel structure plates 1. Multiple threaded rods 23 are installed on the outer surface of the limiting ring 2, and the threaded rods 23 pass through the limiting ring 2 and are threadedly connected to another steel structure plate 1. A limiting sleeve 21 is fixedly connected to the inner wall of the limiting ring 2, and the limiting sleeve 21 is sleeved on the outer surface of the connecting sleeve 35. A limiting groove 22 is formed on the inner wall of the limiting sleeve 21. The limiting groove 22 is engaged with the rotating block 36.

[0029] The overall effect of this embodiment is that, after the locking operation is completed, a limiting sleeve 21 can be fitted onto the outer surface of the connecting sleeve 35 to ensure that the limiting sleeve 21 can effectively protect the rotating block 36 and prevent external forces from causing adverse effects on it. At this time, one end face of the rotating block 36 is in close contact with the steel structure plate 1, forming a firm physical contact, ensuring that the rotating block 36 is not easily displaced or shifted.

[0030] The cooperation between the limiting sleeve 21 and the rotating block 36 not only prevents the rotating block 36 from being subjected to external impacts through a physical barrier, but also effectively prevents it from moving unexpectedly due to external forces. Simultaneously, one end of the rotating block 36 is fixed to the connecting piece via the locking sleeve 33, and through their combined action, the locking effect is significant, ensuring that the rotating block 36 cannot move freely throughout the entire operation. This dual protection not only enhances the stability of the rotating block 36 but also ensures the safety and reliability of the system components under severe external forces.

[0031] Furthermore, the limiting sleeve 21 incorporates a limiting groove 22, which provides additional protection. The limiting groove 22 effectively guides and restricts the movement trajectory of the rotating block 36 under stress, ensuring it remains in the correct position and preventing structural damage or connection failure due to improper displacement. Therefore, the design of the limiting sleeve 21 and the limiting groove 22 optimizes the stability of the entire installation connection, significantly improving the system's overall anti-interference capability and safety, especially under dynamic loads or impacts.

[0032] The device is used as follows: After two steel structure plates 1 are connected, one end of the connecting sleeve 35 is passed through the two steel structure plates 1. At this time, the elastic force of the spring 38 pushes the sliding frame 39 to move along the outer surface of the sliding rod 37. The sliding frame 39 drives the two rotating blocks 36 to move. Under the limiting action of the movable groove 351, the two rotating blocks 36 gradually rotate and unfold from the movable groove 351, making that end of the connecting sleeve 35 unable to move. Then, the locking sleeve 33 is rotated, causing it to move along the outer surface of the threaded sleeve 34 until one end of the locking sleeve 33 abuts against the side wall of one of the steel structure plates 1. In this way, the locking at the connection of the two steel structure plates 1 is achieved through the cooperation of the rotating block 36 and the locking sleeve 33, preventing the connection from becoming loose.

[0033] After locking, a limiting sleeve 21 can be fitted onto the outer surface of the connecting sleeve 35 to protect the rotating block 36 from external forces. At this time, one end of the rotating block 36 is pressed against the steel structure plate 1 and cannot move freely under the cooperation of the locking sleeve 33. The limiting groove 22 also provides protection for it, further enhancing the stability of the installation connection.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
