Abstract
The utility model relates to an expansion clinch bolt, which is composed of an expansion pipe and a steel core. The lower part of the expansion pipe is provided with a tapered groove with variable diameters, and the lower part forms the taper. The upper end of the expansion tube is provided with a bolt cap, and the lower end is provided with fixed teeth. The steel core is in the shape of the column and is positioned inside the expansion pipe. The utility model has a simple structure, low cost, convenient installation, smooth installation surface, and good theft protection property. The utility model can be normally used for narrow places and solve the problem that the expansion bolt can not be used in the narrow places.
Description
The utility model relates to a kind of expansion riveting bolt.
EXPANSION ANCHOR BOLTS of the prior art, the structure relative complex, cost height, and installation and processing is cumbersome, particularly the structure body that adopts EXPANSION ANCHOR BOLTS to install and fix in some public places, easily stolen after unclamping bolt, cause damage to national wealth, EXPANSION ANCHOR BOLTS is appeared after installing in addition, and some combination with decorative surfaces light requirements are sliding smooth, EXPANSION ANCHOR BOLTS is difficult to use, and particularly the narrow positions EXPANSION ANCHOR BOLTS can't be used at all.
The purpose of this utility model is to design a kind of expansion riveting bolt, and simple in structure, cost is low, and installation and processing is convenient, do not appear after the installation, attachment face is smooth smooth, and is difficult to pull down, theftproof performance is good, and narrow positions also can normally be used, and has solved EXPANSION ANCHOR BOLTS in the out of use difficult problem of narrow positions.
Design proposal of the present utility model: expansion riveting bolt, constitute by expansion tube (1) and steel core (2), expansion tube (1) bottom is shaped on taper reducing groove (3), make expansion tube (1) bottom form tapering, expansion tube (1) upper end is shaped on bolt cap (4), and the lower end is shaped on fixing tooth (5), and fixing tooth (5) external diameter is less than or equal to expansion tube (1) external diameter, steel core (2) is cylindrical, and is positioned at expansion tube (1).Expansion tube (1) bottom is shaped on four taper reducing grooves (3) and four fixing tooth (5), and four taper reducing grooves (3) and four fixing tooth (5) are " ten " shape and evenly distribute.Steel core (2) upper and lower end all is shaped on 45 ° of chamferings.
The utility model compared with prior art, and is simple in structure, and cost is low, and installation and processing is easy, and do not appear after installing, and attachment face is smooth smooth, and is difficult to pull down, and theftproof performance is good, can normally use in narrow positions in the same old way.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure of steel pole schematic representation.
Fig. 3 is the utility model user mode reference drawing.
With reference to Fig. 1,2,3 and specification the 5th part a kind of embodiment of the present utility model is described.Expansion tube (1) is a steel pipe, make bolt cap (4) behind its top punching press flange, the bottom punching press is shaped on four taper reducing grooves (3), make expansion tube (1) bottom form tapering, four taper reducing grooves (3) are " ten " shape and evenly distribute, and expansion tube (1) lower end is separated into four, these four punching press flange are made four then and be the uniform fixing tooth (5) of " ten " shape, steel core (2) is that real core is cylindrical, and 45 ° of upper and lower end chamferings, is loaded in the expansion tube (1).During installation, on body of wall, stamp earlier diameter and the identical hole of expansion tube (1) external diameter, be inserted in the hole then, impact the steel core (2) that is positioned at expansion tube (1) with the iron chains head at last, make it with after the expansion tube outer end is concordant, then expansion tube (1) bottom tapering is eliminated, its diameter is identical with the upper end, and fixing tooth (5) embeds in the body of wall under the extruding of steel core (2), and expansion riveting bolt is securely fixed on the body of wall very much, is difficult for pulling down.
Claims (3)
1, a kind of expansion riveting bolt, constitute by expansion tube (1) and steel core (2), it is characterized in that: expansion tube (1) bottom is shaped on taper reducing groove (3), make expansion tube (1) bottom form tapering, expansion tube (1) upper end is shaped on bolt cap (4), and the lower end is shaped on fixing tooth (5), and fixing tooth (5) external diameter is less than or equal to expansion tube (1) external diameter, steel core (2) is cylindrical, and is positioned at expansion tube (1).
2, expansion riveting bolt according to claim 1 is characterized in that: expansion tube (1) bottom is shaped on four taper reducing grooves (3) and four fixing tooth (5), and four taper reducing grooves (3) and four fixing tooth (5) are " ten " shape and evenly distribute.
3, expansion riveting bolt according to claim 1 is characterized in that: steel core (2) upper and lower end all is shaped on 45 ° of chamferings.
