Abstract
The utility model relates to a fastener of a cellular board. The fastener is connected with the cellular board, and a support board is arranged between a connecting position of the outer surface of the cellular board and the fastener. The support board is arranged between the connecting position of the outer surface of the cellular board and the fastener, an stressed area between the fastener and the cellular board is increased, and the problems that the cellular core materials inside the cellular board are damaged and are delaminated due to the fact that the fastener bears large loading for a long time is avoided. In addition, a screw bolt or a screw is in threaded connection with the support board, and equipment, an instrument and the like can be installed and fixed at any time. When the equipment and the instrument are not used, the equipment and the instrument can be taken down at any time, and the fastener of the cellular board is convenient to dismount and install.
Description
Technical field
The utility model relates to a kind of fastener, is specifically related to a kind of fastener for being connected with cellular board.
Background technique
Existing cellular board generally is comprised of upper covering, lower covering and comb core, and comb core is clipped between covering and lower covering.Equipment in the cellular board cabin, instrument etc. are all generally to be fixed with fastener at present; And fastener is of a great variety, mainly contains at present: rivet, bolt etc.The rivet kind is more, and commonly used have cup head, tack, semitubular rivet, solid rivet, sunk head rivet, self-plugging rivet, a tubular-shank rivet etc., normally utilizes self deformation to connect by riveting parts; Bolt is the cylindrical threaded fastening piece of adapted nut, is used for being fastenedly connected two with the part of through hole, belongs to removably connect.These two kinds of fastener application occasions are more.
Yet during as the fastener of cellular board, there are following problem in rivet and bolt:
(1) fastener such as rivet, bolt can destroy the sealability of cellular board, causes the problems such as cellular board infiltration;
(2) rivet, bolt are subject to the problems such as delamination that larger load can cause cellular board for a long time;
(3) the solid power of rivet, bolt system little, can't arbitrarily install, easily cause the problem such as cellular board damage.
The model utility content
The utility model is to provide a kind of is convenient to random installation, in the situation that not destroy cellular board can be solid firmly cellular board fastener.
Concrete technological scheme of the present utility model is as follows:
A kind of cellular board fastener, this fastener is connected with cellular board, is provided with dunnage between the joint of cellular board outer surface and fastener.
Described fastener comprises double-screw bolt, and double-screw bolt is wholely set perpendicular to dunnage and with dunnage, and described dunnage is connected with the outer surface of cellular board away from the surface of double-screw bolt.
A surface of described dunnage is connected with the outer surface of cellular board, and dunnage is provided with the tapped through hole vertical with the cellular board outer surface; Described fastener comprises double-screw bolt, and an end of double-screw bolt is connected with the through hole whorl on dunnage.
Described fastener comprises nut and supporting post, and an end of nut connects dunnage, and nut is embedded in the mounting hole of cellular board and exposes dunnage at the outer surface of cellular board; Dunnage is provided with the tapped through hole vertical with the cellular board outer surface, and the tapped through hole on dunnage is connected and coaxial setting with the tapped through hole of described nut, and the tapped through hole on dunnage is identical with the aperture of the tapped through hole of described nut; One end of supporting post adopts with dunnage and nut and is threaded.
Described supporting post is screw.
For easy to process, described nut and dunnage are one-body molded.
Above-mentioned dunnage is circular plate.
The utility model is provided with dunnage between the joint of cellular board outer surface and fastener, increased the lifting surface area between fastener and cellular board, avoided fastener to be subject to for a long time larger load and make the delamination problems that in cellular board, comb core is damaged and causes comb core in cellular board.Double-screw bolt or screw are threaded with dunnage in addition, can at any time equipment, instrument etc. be installed fixing; When not needing to use, also can at any time equipment, instrument be taken off easy accessibility.
