Abstract
Description
Technical Field
[0001] This utility model relates to the field of truss connector technology, and in particular to an adjustable truss connector. Background Technology
[0002] Trusses are planar or spatial structures composed of straight bars and generally have triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, they can save material, reduce self-weight and increase stiffness compared to solid web beams.
[0003] Existing trusses require multiple truss connectors for auxiliary installation during the installation process. Most of these connectors are fixed or threaded with multiple bolts. Rigid fixed connections make subsequent disassembly inconvenient, while multiple bolts make disassembly cumbersome and inconvenient. As a result, existing truss connectors have limited practicality. Therefore, we propose an adjustable truss connector. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art and provide an adjustable truss connector.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable truss connector, comprising a truss, wherein the truss is rigidly connected by columns and supports, a first connecting shaft is provided between every two sets of trusses, a second connecting shaft is integrally formed on the outside of the first connecting shaft, limit connectors are installed at both the upper and lower ends of the first connecting shaft, limit mounting grooves are provided at both the upper and lower ends of the column, connecting threads are provided on the outer periphery of both ends of the first connecting shaft, threaded bushings are threaded on both ends of the first connecting shaft through the connecting threads, locking threads are provided on the outer periphery of both the upper and lower ends of the column, and limit ends are fitted on the outer periphery of both the upper and lower ends of the column.
[0006] Preferably, each pair of the support columns is connected to the limiting connectors at the upper and lower ends of the first connecting shaft through a limiting installation groove, and each pair of the trusses is in a limiting support state through the first connecting shaft.
[0007] Preferably, after the limiting mounting grooves at both ends of the support column are limited and connected with the limiting connectors at both ends of the first connecting shaft, when the threaded bushing outside the first connecting shaft is rotated and adjusted to be connected with the limiting end at one end of the support column, the connecting thread on the periphery of the first connecting shaft and the locking thread on the periphery of the support column are in an integral threaded locking state through the threaded bushing.
[0008] Preferably, the connecting threads around the first connecting shaft and the locking threads around the support are covered with threaded gaskets, and the threaded gaskets themselves have deformation characteristics.
[0009] Preferably, when the threaded bushing is threadedly connected to the connecting thread on the periphery of the first connecting shaft and the locking thread on the periphery of the support, the threaded pads on the surfaces of the connecting thread and the locking thread are in a biting and limiting state through the threaded bushing.
[0010] This utility model provides an adjustable truss connector. It has the following advantages:
[0011] 1. In this adjustable truss connector, when multiple trusses are installed and connected, the limiting installation grooves at one end of each pair of columns can be inserted into the limiting connectors at the upper and lower ends of the first connecting shaft. Then, the threaded bushing outside the first connecting shaft is rotated and adjusted, and the locking thread is used to lock the connection with one end of the column until it is connected to the limiting end. The second connecting shaft outside the first connecting shaft can also be connected to other trusses at multiple angles laterally. In this way, the first connecting shaft and the column can be quickly connected and locked, and disassembly is the same, thereby improving the practicality of the first connecting shaft.
[0012] 2. In this adjustable truss connector, the connecting threads on the periphery of the first connecting shaft and the locking threads on the periphery of the support are both covered with threaded pads. The threaded pads themselves have deformation characteristics. When the threaded sleeve moves to connect with the connecting threads on the periphery of the first connecting shaft and the locking threads on the periphery of the support, the threaded sleeve can engage with the threaded pads on the connecting and locking threads to limit the movement. This increases the installation friction between the first connecting shaft and the support. When the truss vibrates, the threaded sleeve on the support and the first connecting shaft can be cushioned by the deformation of the threaded pads on the connecting and locking threads, reducing vibration and wear, thereby improving the installation stability between the support and the first connecting shaft.

[0022] 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.
[0023] Example: An adjustable truss connector, such as Figures 1-5As shown, the structure includes a truss 1, which is rigidly connected by supports 2 and struts 3. A first connecting shaft 4 is provided between every two sets of trusses 1. A second connecting shaft 5 is integrally formed on the outside of the first connecting shaft 4. Limiting connectors 6 are installed at both the upper and lower ends of the first connecting shaft 4. Limiting mounting grooves 7 are provided at both the upper and lower ends of the supports 2. Connecting threads 8 are provided on the outer periphery of both ends of the first connecting shaft 4. Threaded bushings 9 are threaded onto both ends of the first connecting shaft 4 through the connecting threads 8. Locking threads 10 are provided on the outer periphery of both the upper and lower ends of the supports 2. Limiting ends 11 are installed on the outer periphery of both the upper and lower ends of the supports 2. Threaded gaskets 12 are provided on the surfaces of the connecting threads 8 on the outer periphery of the first connecting shaft 4 and the locking threads 10 on the outer periphery of the supports 2. The threaded gaskets 12 themselves have deformation characteristics.
[0024] Furthermore, each pair of support columns 2 is connected to the limiting connectors 6 at the upper and lower ends of the first connecting shaft 4 via the limiting installation groove 7, and each pair of trusses 1 is in a limiting support state via the first connecting shaft 4.
[0025] Furthermore, after the limiting mounting grooves 7 at both ends of the support column 2 are limited and connected with the limiting connecting parts 6 at both ends of the first connecting shaft 4, when the threaded bushing 9 outside the first connecting shaft 4 is rotated and adjusted to move to connect with the limiting end 11 at one end of the support column 2, the connecting thread 8 on the periphery of the first connecting shaft 4 and the locking thread 10 on the periphery of the support column 2 are in an integral threaded locking state through the threaded bushing 9.
[0026] Furthermore, when the threaded bushing 9 is threadedly connected to the connecting thread 8 on the periphery of the first connecting shaft 4 and the locking thread 10 on the periphery of the support column 2, the threaded pads 12 on the surfaces of the connecting thread 8 and the locking thread 10 are in a biting and limiting state through the threaded bushing 9.
[0027] The working principle of this utility model:
[0028] When installing and connecting the multiple sets of trusses 1, the limiting installation grooves 7 at the ends of each pair of columns 2 that are close to each other can be inserted into the limiting connectors 6 at the upper and lower ends of the first connecting shaft 4 for limiting and insertion. Then, the threaded bushing 9 on the outside of the first connecting shaft 4 is rotated and adjusted, and then threadedly locked to one end of the column 2 through the locking thread 10 until it is connected to the limiting end 11. The second connecting shaft 5 on the outside of the first connecting shaft 4 can also be connected and installed laterally at multiple angles with other trusses 1. In this way, the first connecting shaft 4 and the column 2 can be quickly connected, locked, and disassembled. When the threaded bushing 9 moves to connect with the connecting thread 8 on the periphery of the first connecting shaft 4 and the locking thread 10 on the periphery of the support column 2, the threaded bushing 9 can engage with the threaded pads 12 on the surfaces of the connecting thread 8 and the locking thread 10 to limit the movement. This increases the installation friction between the first connecting shaft 4 and the support column 2. When the truss 1 vibrates, the threaded bushing 9 on the outside of the support column 2 and the first connecting shaft 4 can be cushioned by the deformation of the threaded pads 12 on the surfaces of the connecting thread 8 and the locking thread 10, thus reducing vibration and wear.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
