Abstract
The utility model relates to an expansion bolt particularly adequate to be used for mounting objects, composed of a cone nut, an expansion sleeve and a hexagon-head bolt. A flange is arranged on the cone nut and is embedded inside a stripping edge of the expansion sleeve. The stripping edge of the expansion sleeve is tightly clamped inside a dietella wall. Solving the defect that the existing expansion screw-rod is easy to slip and can be taken out only when the wall is smashed, the utility model has the advantages of simple structure and no specific requirement for the processing technology, and can effectively prevent from slipping as well as can be taken out from the wall hole.
Description
A kind of EXPANSION ANCHOR BOLTS.
Existing expansive screw is made of cone single-head screw and expansion sleeve and hexagon nut.The cone single-head screw is embedded in the expansion sleeve, during installation, hexagon nut is tightened, the expansion sleeve packing between the cone of this bar, be convenient to expansion sleeve is together knocked in porthole, like this, threaded end is just yielding, simultaneously, this expansive screw also skids easily, for this phenomenon, normally clamp threaded end with pliers, tighten hexagon nut and just can not skid.Once use, cone single-head screw and expansion sleeve just can not take out in porthole, otherwise, must crack wall and just can take out.
The purpose of this utility model is a kind of improved EXPANSION ANCHOR BOLTS of the public, and it can be fixedly mounted in the porthole, and not broken wall also can take out.
Task of the present utility model is finished as follows: make to have flange on cone nut, being embedded in expansion sleeve one end does in crannied the edge, its purpose is to make the flange on the cone nut to be stuck in the expansion sleeve and can not rotates, the bar edge of expansion sleeve is stuck in the porthole wall and can not rotates, prevented to skid, be through in the object hole with the standard piece hexagon head bolt and be screwed into, can reach reliable installation.The needs different according to object also can use the standard piece double threaded screw.
After expansion sleeve is made to have the other end of crack bar edge, done to have a baffle ring, its purpose to be that EXPANSION ANCHOR BOLTS is used, in the time of need taking off object again, be convenient to expansion tube knocked in or catch on baffle ring and take out in the porthole and be provided with.
The utility model compared with prior art has following beneficial effect:
(1), simple in structure.The utility model is made of cone nut and expansion sleeve and hexagon head bolt, and making it part, cost, technology does not have increase.
(2), use saves time.It is knocked in the porthole, can firmly object be installed tighten hexagon head bolt, work promptly comes to an end; This part can take out in porthole again simultaneously, has overcome existing expansive screw and has cracked the drawback that wall could take out.
(3), installation is attractive in appearance.After object was installed, hexagon head is only exposed in the outer end, and was promptly smooth, attractive in appearance again.
Below with reference to drawings and Examples concrete structure of the present utility model is further described.
Description of drawings:
Fig. 1 cuts open figure for EXPANSION ANCHOR BOLTS structure office;
Fig. 2 is an A-A sectional view in Fig. 1 EXPANSION ANCHOR BOLTS.
With reference to accompanying drawing, a kind of cone nut of EXPANSION ANCHOR BOLTS (1) is a cylindrical female pipe, makes to have flange (5) on the cylndrical surface, and an end makes to have the cone greater than cylindrical outer diameter, and it equals the external diameter of expansion sleeve (3); Do and manage the crack that inner cavity communicates vertically at expansion sleeve (3) one ends, the body on limit, crack outwards makes to have bar edge (2), and its other end work in pipe has baffle ring (6).Cone nut (1) cylindrical end embeds in the pipe inner cavity of expansion sleeve (3) crack end, allow flange (5) be stuck in the bar edge (2), hexagon head bolt (4) is a standard piece, stretches on the screw thread that its cavity is screwed in cone nut (1) from the baffle ring (6) of expansion sleeve (3) end.
During use, this part cone nut (1) cone end is inserted porthole, knock hexagon head bolt (4), with the heavy flat porthole face of baffle ring (6) end of expansion sleeve (3), the bar edge (2) on the expansion sleeve (3) just is clamped in the porthole wall; Be through in the object hole with hexagon head bolt (4) and be screwed into again, cone nut (1) is along with hexagon head bolt (4) constantly twists, and cone is drawn in the expansion sleeve (3), makes the expansion of expansion sleeve (3) body and bar edge (2), reaches reliable installation.After using, in the time of must taking off object again, the hexagon head bolt of back-outing (4), take off object after, can see on the porthole face and the baffle ring (6) of expansion sleeve (3) knock baffle ring (6) to porthole, the finishing metope of can plastering.If also need recycle, hexagon head bolt (4) is screwed on the cone nut (1) again, or the cone of cone nut (1) is struck from expansion sleeve (3) afterwards with instruments such as screw-drivers, collude instrument with a band and catch on baffle ring (6) on expansion sleeve (3) port, pull out, again cone nut (1) is taken out simultaneously, can plaster the finishing metope.
Claims (3)
1, a kind of being particularly suitable for installed the EXPANSION ANCHOR BOLTS that object uses, and it comprises cone nut (1), expansion sleeve (3), hexagon head bolt (4), it is characterized in that cone nut (1) is embedded in the expansion sleeve (3).
2, EXPANSION ANCHOR BOLTS according to claim 1 is characterized in that cone nut (1) one end work has flange (5), and the other end makes to have cone.
3, EXPANSION ANCHOR BOLTS according to claim 1 is characterized in that expansion sleeve (3) one ends work has the body on crack, limit, crack to make to have bar edge (2), and the other end makes to have baffle ring (6).
