Abstract
The utility model relates to an expansion bolt, particularly an expansion bolt with double-direction expansions. The utility model is composed of a screw bolt, an expansion cylinder and a screw nut. The utility model is characterized in that a slide block is added, the slide block is a round table provided with a central hole; the screw bolt is a screw bolt with a big sunk head; 4 to 6 slits are respectively opened at both ends of the expansion cylinder. The screw bolt penetrates the expansion cylinder, the side block is sheathed at one end of a screw bolt screw thread, forming a whole screwed by a screw nut. A screw hole and a groove are opened at the center of a head part of the screw bolt and the expansion bolt can be tightly screwed by inserting a screwdriver into the concave groove at the head part of the screw bolt. The expansion bolt has double-direction expansions and both ways can be used. The utility model is suitable for various building decoration.
Description
The utility model relates to a kind of expansion bolt, particularly has the expansion bolt of two-way expansion.
Domestic widely used expansion bolt is unidirectional expansion bolt at present, and its structure is made up of bolt, expansion cylinder and nut, and an end of expansion cylinder has 4 slots, bolt penetrates from the end that slot is arranged, bolt head is stayed the outside, and bolt tail stretches out from the other end, screws by nut.During use, an end that expansion cylinder is had slot places in the wall hole, and bolt tail stretches out body of wall, and behind the fastening nut, bolt head plays fastening effect with expansion cylinder slot distending, and its shortcoming is unidirectional expansion, causes the installation tightness poor, rocks easily, and is insecure.
The purpose of this utility model provides a kind of tightness height, does not rock the two-way expansion bolt of energy load-bearing thing.
The utility model is achieved in that existing expansion cylinder one end is had slot to be changed two ends into and all have slot, and sets up a slide block.
Referring to Fig. 1, the utility model structural representation, a kind of two-way expansion bolt comprises bolt (1), expansion cylinder (2) and nut (3), it is characterized in that being provided with a slide block (4), slide block (4) is a round platform, has center hole; Bolt (1) is big countersunk screw; Expansion cylinder (2) two ends respectively have 4-6 bar slot (7), and bolt (1) penetrates expansion cylinder (2), and slide block (4) is enclosed within bolt (1) screw thread one end, are screwed by nut (3) to be integral.
Bolt (1) head center has screw (5).Bolt (1) head center has groove (6).
Slide block (4) center hole is provided with screw thread.
Slide block (4) and nut (3) are an integral body.Just can be processed into the slide block that has nut.
Bolt (1) head can be made hexagon.
During use, bolt head one end is placed in the wall hole, bolt tail stretches out body of wall, and during fastening nut, bolt head and slide block be from two ends extrusion expansion tube, and the slot at two ends is by distending, plays two-way expansion and fastening.
Another kind of usage mode is placed on the bolt tail end in the wall hole, and expansion cylinder outer end and metope are evened up, and screw in the groove with screw-driver inserting bolt head.At this moment, bolt head and slide block be from two ends extrusion expansion tube, and the slot at two ends is by distending, plays two-way expansion and fastening.Fixedly during hanger, in screw inserting bolt head screw, screw and get final product.
The two-way expansion of this expansion bolt, two kinds of modes are used, and are applicable to various construction and decorations.
