Abstract
The utility model aims at providing a detachable combined type anti-loosening and anti-slipping expansion bolt. The expansion bolt comprises a screw rod, a left-end conical-platform-shaped expansion head, an expansion pipe, a right-end conical-platform-shaped expansion head, a pressing pipe, a spring gasket and a nut, wherein the left-end conical-platform-shaped expansion head, the expansion pipe, the right-end conical-platform-shaped expansion head, the pressing pipe, the spring gasket and the nut are sequentially sleeved on a screw rod. The left-end conical-platform-shaped expansion head is provided with two anti-slipping ribs; the expansion pipe is provided with an expansion opening and a net-shaped anti-slipping groove is arranged on the surface of the expansion pipe; the spring gasket is concave rightwards; and the detachable combined type anti-loosening and anti-slipping expansion bolt can adopt two sets of conical-platform-shaped expansion head and the expansion pipe to be sleeved on a lengthened screw rod and the middle conical-platform-shaped expansion head is in butt joint. The designs of the net-shaped anti-slipping groove of the expansion pipe, the two anti-slipping ribs on the left-end conical-platform-shaped expansion head, the concave spring gasket and the like are adopted, so that the expansion bolt is stressed and deformed uniformly, mounting equipment can be firmly fixed and potential safety hazards caused by insufficient vibration or expansion force are avoided.
Description
Technical field
The utility model relates to a kind of EXPANSION ANCHOR BOLTS, relates in particular to a kind of Assembled type locking antiskid EXPANSION ANCHOR BOLTS.
Background technique
EXPANSION ANCHOR BOLTS, be make that airduct props up, hangs, carriage is fixing on the wall, used a kind of special thread link on the floor, on the post.During use, must be first get out the hole of corresponding size with electric impact drill (hammer) at fixed body, again in bolt, the expand tube load hole, screw nut and can make that swelling is integral between bolt, expand tube, assembling set and the fixed body.Dilatable after tightening, bolt tail has a major part, pipe slightly larger than the diameter of bolt of the outer surface cover of bolt, the afterbody part has several roads opening, and behind bolt tightening, the afterbody of major part just is brought to the pipe the inside of opening, large the pipe punching, reach the purpose of expansion, and then being bolted on ground or the wall, reach the purpose of taking root.
EXPANSION ANCHOR BOLTS in the past in use exist expansive force not, unbalance stress, easy quality problems such as loosening, discarded EXPANSION ANCHOR BOLTS is unloaded to get off, and makes troubles for on-the-spot the use, has potential safety hazard.
The model utility content
Problem to be solved in the utility model provide a kind of stress deformation evenly, the EXPANSION ANCHOR BOLTS of locking antiskid device is arranged, can avoid causing because vibrations or expansive force are not enough loosening, the stability, reliability and the Security that improve product.
The technical solution of the utility model is as follows: a kind of Demountable combined-type locking antiskid EXPANSION ANCHOR BOLTS, comprise screw rod, the swollen head of left end circular cone shape, expand tube, the swollen head of right-hand member circular cone shape, pressure pipe, spring washer, nut, the expand swollen head of head, expand tube, right-hand member circular cone shape, pressure pipe, spring washer, nut of described left end circular cone shape is sleeved on the screw rod successively, it is characterized in that: described expand tube two ends are provided with inflation openings, described expand tube surface is provided with the mesh antiskid groove, described spring washer is curved, caves in to the right in the center.
Further, the swollen side of described left end circular cone shape is provided with some anti-skidding muscle.
Further, described anti-skidding muscle is two, and described anti-skidding muscle was positioned at cross section, the center of circle and intersection, circular cone side.
Further, the described left end circular cone shape swollen head of head, expand tube, right-hand member circular cone shape that expands is considered as a cover combination, adds to be set with the described combination of two covers on the long bolt.
The beneficial effects of the utility model are: by the design of netted anti-slip tank on the utility model expand tube, when the stressed dilatancy in EXPANSION ANCHOR BOLTS two ends, mesh antiskid groove on the expand tube is caught the inner cylindrical surface object that is inflated tightly, firmly the equipment of installing is fixed; The design of two anti-skidding muscle and spill spring washer by the swollen head of left end circular cone shape makes the EXPANSION ANCHOR BOLTS stress deformation even, has avoided the potential safety hazard that causes because of vibrations or expansive force deficiency.
