Abstract
Disclosed is an expansion bolt, belonging to products of screws, which is formed by a screw rod (1) whose one end is hollow, a frustum cone shaped pin (5), a gasket (2), a spring gasket (3) and a screw cap (4). The top of the screw rod (1) is circular arc shaped; when used, the pin (5) is propped on one end of the screw rod, which is hollow and one end of the screw rod, which is hollow is pushed into a hole which is drilled in advance; the top of the screw rod (1) is stroke, the screw rod is expanded by the pin (5) to make the screw rod is expanded tightly with the wall of the hole, and therefore, the new expansion bolt is firmly fixed on a fixed object. The utility model has the advantages of materials saving, installation saving, labor saving and time saving.
Description
The utility model belongs to the screw series products, is a kind of upset bolt, and now general EXPANSION ANCHOR BOLTS mainly is by tail end periphery projection pulls out slightly the screw rod of shape and the ferule that is overlapping in its outside and form, and has several slits in the bottom of ferule.The fastening piece of this structure needs the set body is holed in advance in use, and hole diameter should be more bigger than ferule external diameter, and the rolled steel dosage of this EXPANSION ANCHOR BOLTS is more, and also bigger to the diameter of set body boring, installs more time-consuming.
The purpose of this utility model is for a kind of upset bolt without ferule is provided.It can reduce the materials being fabricated of bolt and change little diameter of holing on the set body, installs saving of work and time.
The implementation of concrete structure of the present utility model and its purpose is provided by following embodiment and accompanying drawing thereof.
Fig. 1 Fig. 3 is the part schematic representation of upset bolt.
Fig. 2 is the part sectioned view of screw rod.
Fig. 4 is the working state assembling schematic representation of upset bolt.
Upset bolt is made up of screw rod (1), packing ring (2), spring washer (3) nut (4) and pin (5).One end of screw rod (1) is shaped on screw thread, and the top is a circular arc; An other end hollow, in a tubular form, tubulose partly has several slits vertically.Another part pin (5) is truncated cone, is shaped on the flexuose fin on the inclined-plane, pin (5) and the supporting use of screw rod (1).On the set body, bore a hole more bigger during installation earlier than screw diameter, the tip of pin (5) is headed into an end of screw rod (1) cannulated, push in the hole then, after pin (5) arrives the hole bottom, hit the top of screw rod (1) with hammer, make the hollow of screw rod (1) partly pack into pin (5), screw rod (1) is just stung tightly together with pin (5), the afterbody of the bloated screw rod (1) of pin (5) support simultaneously, the afterbody distending of screw rod (1) and the hole wall swelling of set body, reach the purpose of fixing bolt, just the object that will fix can be installed later.The top of screw rod (1) is a circular arc, in order that make it at the unlikely gross distortion in back that catches a packet, reaches the purpose of protection screw thread.
The advantage of the utility model is to have replaced ferule with pin, and total rolled steel dosage has been reduced, and owing to changing of bore diameter on the set body is little, therefore installs the comparison saving of work and time.
