Abstract
The utility model relates to an expanding bolt, comprising an expanding bolt, an expanding sleeve tube and a screw nut. The utility model is characterized in that a circular cylinder is arranged on the tail cone shape of the expanding bolt, and the utility model has the advantages of enabling the expanding bolt to have no shaking after installed and enlarging the traction force of the expanding bolt.
Description
The utility model relates to a kind of expansion bolt.
The bolt tail of at present general expansion bolt is a cone type, in use because conical tail end is beveled end contact, therefore rock easily in the time of in expansion bolt is placed on the hole, and the point of contact of the overcoat of beveled end and expansion bolt is little, the painstaking face of expansion bolt is little, and the pulling force of expansion bolt is little.
Do not have after the purpose of this utility model provides and installs and shake the expansion bolt that pulling force is big.
The technical solution of the utility model is a kind of expansion bolt of design, comprises expansion bolt, swollen ringfeder pipe, it is characterized in that: on the expansion bolt tail end cone type cylindrical body is arranged.
The utility model has the advantages that can make expansion bolt that the back is installed does not have the pulling force that shakes and strengthen expansion bolt.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing is a schematic representation of the present utility model, comprise expansion bolt 1 among the figure, swollen ringfeder pipe 2, nut 5, it is characterized in that: on the expansion bolt 1 tail end cone type 3 cylindrical body 4 is arranged, during use expansion bolt 1 is put into the hole of accomplishing fluently, because the effect expansion bolt 1 of cylindrical body 4 can not shake, swollen ringfeder pipe 2 is enclosed within on the expansion bolt 1, firmly knock swollen ringfeder pipe 2, cylindrical body 4 on the expansion bolt 1 tail end cone type 3 is folded mutually with swollen ringfeder pipe 2, when tightening with nut 5, because cylindrical body 4 is big with the surface of contact of swollen ringfeder pipe 2, therefore strengthen the pulling force of expansion bolt widely.
