Description

Technical Field

[0001] The present application relates to the field of decoration accessories, and in particular to a thermal insulation nail. Background Art

[0002] Insulation nails are special engineering plastic expansion nails that fix insulation boards to walls. Insulation nails are special anchors for exterior wall insulation and are widely used in building decoration.

[0003] Insulation nails are mainly composed of screws, expansion tubes and fixed discs. Insulation nails are also used to connect external structures to insulation walls. For example, when building pipelines, the pipelines and insulation walls can be connected by insulation nails. While fixing the insulation wall and the pipeline, the insulation wall and the pipeline are separated, reducing heat transfer between the pipeline and the insulation wall, making it less likely for cold and hot bridges to appear in the insulation wall.

[0004] In the actual construction process, workers need to reserve positioning holes on the insulation wall according to the location of the connecting pipes, and screws and expansion tubes are inserted through the through holes to connect to the insulation wall. The fixed disc has a through hole for the screw to pass through, and the fixed disc is used to connect to the pipe. When there is an error in the positioning hole, the through hole is not connected to the pipe connection after the screws and expansion tubes are inserted through the through hole. At this time, another positioning hole needs to be opened and reinstalled, which affects the installation efficiency and needs to be improved. Utility Model Content

[0017] Preferably, a plurality of positioning holes are formed on the fixed disc, the positioning holes are communicated with the guide grooves, the positioning member is a positioning rod, the positioning rod is slidably connected to the mounting plate, and the positioning holes are used for the positioning rod to be snapped into position.

[0018] By adopting the above technical solution, in actual use, after the fixing disc is fixed to the external structure, the positioning rod is moved into the positioning hole to position the installation piece, making it convenient to position the installation piece.

[0019] Preferably, a magnetic member is provided on the fixed disc, and the magnetic member is used to adsorb the positioning rod, and the magnetic member is located on a side of the positioning rod close to the positioning hole.

[0020] By adopting the above technical solution, when the external structure is fixed to the fixed disc, the magnetic part absorbs the positioning rod, so that the positioning rod automatically moves and extends into the positioning hole. By the magnetic part absorbing the positioning rod, the positioning rod is not easy to be separated from the positioning hole after being stuck in the positioning hole, which is conducive to improving the positioning stability.

[0021] Preferably, a plurality of reinforcing ribs are provided between the fixing disc and the expansion tube, and the reinforcing ribs are located between adjacent mounting plates.

[0022] By adopting the above technical solution and providing reinforcing ribs, the sheet connection strength between the fixed disc and the expansion tube is increased, so that during the installation process, the fixed disc will not be deformed or damaged due to excessive pressure.

[0023] Preferably, the reinforcing ribs are located on two opposite sides of the fixing disc.
