Abstract
The utility model relates to a fastener, comprising an expanding rod and a sleeve with end sleeved on the outside of the expanding rod; wherein, an inward-inclined expanding sheet is arranged in the lower part of the sleeve; a plurality of outward projections are positioned around the lower end of the expanding sheet; the sleeve has partial interference fit with the expanding rod with slip-limited friction lines on the side surface; and a functional support level of a tool for inserting the expanding rod into the sleeve is positioned on the end. The utility model has no unfavorable influence on the hole-bottom when the expanding rod is inserted into the sleeve and the expanding sheet is expanded and can be widely used in sheet and thinner board of any material. The utility model has the advantages of simple structure and easy mounting of the fastener and the sheet which can be finished in engineering site.
Description
Technical field
The utility model relates to a kind of fastening piece that is applied to sheet of brittle material.
Background technique
Post-cut is sheet of brittle material fixedly, the crab-bolt of employing is arranged at present as fastening piece.In the crab-bolt fastening piece, have at present, because the restriction of structure, when mounted can be to producing active force at the bottom of the hole in hole that crab-bolt is set, thereby can have a negative impact to the intensity of plate even can smash plate, therefore, be difficult to be applied to thousand and think plates, sheet material or thin plate that the glass plate equal strength is not high.Simultaneously, comprise the existing crab-bolt fastening piece of above-mentioned crab-bolt fastening piece, the equal more complicated of structure, and itself and sheet material and comparatively loaded down with trivial details by the installation between its sheet material realized and the sheet material attachment.
Summary of the invention
Can not have a negative impact at the bottom of the hole to hole that crab-bolt is set when technical problem to be solved in the utility model is a kind of the installation is provided, fastening piece simple in structure.For this reason, the utility model is by the following technical solutions: it comprises expanding bar and is placed in the outer sleeve with termination of expanding bar, the bottom of sleeve is intilted expansible, have outside outstanding around expansible underpart, the side surface of expanding bar has on-slip friction line, sleeve and the expanding bar part interference fit with on-slip friction line, the termination has the effect supporting position of the instrument in the sleeve that expanding bar is inserted.Owing to adopt technique scheme, can not be widely used in the sheet material of any material and thin plate when the utility model inserts expanding bar sleeve and expands expansible to producing any adverse effect at the bottom of the hole.And the utility model is simple in structure, and the installation of fastening piece and sheet material is extremely simple, can finish at engineering site.
The utility model also can adopt following further technological scheme simultaneously:
Described effect supporting position is recessed at the termination side surface.
The termination is provided with circular groove, and the upper surface of circular groove is above-mentioned effect supporting position.Like this, can articulate by this circular groove between sheet material and its accompanying thing, be very easy to the installation between them.
The upper side surface of termination is an arc shaped surface, and above-mentioned effect supporting position is located at the below of the arc shaped surface part of termination.Can regulate the setting angle of sheet material like this, thereby make the installation of sheet material can adapt to the attachment of different surfaces shape.
Described effect supporting position is recessed at the termination side surface.
The termination is provided with circular groove below the arc shaped surface part, the upper surface of circular groove is above-mentioned effect supporting position.
