Description

Technical Field

[0001] The utility model belongs to the technical field of cable trays, and particularly relates to a fastening device for a cable tray and a cable tray. Background Technique

[0002] According to the disclosed patent with the patent number CN214626200U, a fastening device for a cable tray, the cable tray of which includes a cover plate and a bottom groove. Fixed holes are provided on the side wall of the bottom groove, and the cover plate is used to be installed on the bottom groove. The device includes a fixed top plate and a fixed side plate. One end of the fixed top plate is fixedly connected to one end of the fixed side plate. By applying a downward force on the cover plate of the cable tray through the fixed top plate, the cover plate and the bottom groove are fastened in the vertical direction. The bottom groove is fixed by the fixed side plate and a clamping ring arranged on the side plate, and the elastic deformation range of the spring steel is increased by the way of the elastic clamping ring. After the clamping ring is inserted into the fixed hole, it is in a clamped state. By providing a tongue piece extending outward at the free end of the clamping ring, when directly pressing the part of the tongue piece extending out of the side hole during installation to cause elastic deformation of the clamping ring, the clamping ring can be inserted into the fixed hole of the bottom groove. While facilitating installation, the fastening degree is ensured by the elastic clamping ring, thus solving the problem that the installation difficulty of the fastening device between the cover plate and the bottom groove of the cable tray is relatively large. However, there are still the following deficiencies, such as:

[0003] The above-mentioned device achieves the purpose of reducing the installation difficulty of the device after completion. However, when installing, multiple cable trays cannot be quickly connected, and the installation height of the device and the cable tray cannot be adjusted in time.
