Abstract
The invention discloses an expansion bolt, which comprises a bolt body, an expansion sleeve and a gasket, wherein a nut matched with the bolt body is fixedly connected with the interior of the tail end of the expansion sleeve, four to six groove holes along the axial direction are arranged in the middle of the expansion sleeve, and the middles of the groove holes expand towards two sides to be provided with grooves. The expansion bolt has the advantages of being good in expansion effect, strong in fastening force, good in reliability, fast and convenient to install, convenient to demount, capable of being reused and the like.
Description
Technical field
The present invention relates to a kind of link, especially relate to a kind of EXPANSION ANCHOR BOLTS.
Background technique
Existing a kind of EXPANSION ANCHOR BOLTS; It comprises bolt, expansion sleeve, and the end of bolt has jut, and the inner face of expansion sleeve is shaped on the internal thread that matches with bolt; And the end of expansion sleeve is provided with open seam; When nut was screwed, the jut of bolt strutted the open seam of expansion sleeve, impelled that swelling becomes as a whole between EXPANSION ANCHOR BOLTS and the connecting body (wall, plate body).Defective below this EXPANSION ANCHOR BOLTS exists: 1, the end of expand tube is in the hollow shape attitude, and weak strength, reliability are relatively poor; 2, after fixation was removed, EXPANSION ANCHOR BOLTS was not easy to take out very much, and people stay among the building removing the EXPANSION ANCHOR BOLTS of fixation often.
Summary of the invention
The purpose of this invention is to provide the EXPANSION ANCHOR BOLTS that a kind of expansion effect is better, bolt is easy to remove.
The present invention realizes through following technological scheme: EXPANSION ANCHOR BOLTS; Comprise the body of bolt, expansion sleeve and packing ring; It is characterized in that: the terminus inner of described expansion sleeve is connected with the nut that matches with the body of bolt; The middle part of described expansion sleeve is provided with 4-6 the slotted eye along axial direction, and the middle part of described slotted eye is expanded to both sides and is provided with groove.
The other end of described expansion sleeve is connected with plain washer, and described plain washer is provided with nail corresponding to the face of expansion sleeve.
Described slotted eye is symmetrical distribution.
The outer surface of described expansion sleeve is provided with the strip jut.
The present invention is owing to be provided with 4-6 the slotted eye along axial direction at the middle part of expansion sleeve, the middle part of slotted eye is expanded to both sides and is provided with groove, make to form on the expansion sleeve than the number of slotted eye Duo one rib, and rib is, and two ends is big, the centre is little.
When nut and body of bolt locking, expansion sleeve is under the effect of axial compression power, and its weakness produces radial displacement immediately, because the expansion sleeve inwall receives the obstruction of the body of bolt, expand tube can only outwards be expanded, and forms drum shape until reaching the fixing purpose of swelling.
Further, the other end of described expansion sleeve is connected with plain washer, and described plain washer is provided with nail corresponding to the face of expansion sleeve; During use, expansion sleeve is put into the hole of on body of wall, accomplishing fluently in advance, plain washer places on the outer surface of body of wall; Use external force; Ailing on the plain washer is gone in the body of wall, when the locking nut and the body of bolt, can prevent skidding.
Further, the outer surface of described expansion sleeve is provided with the strip jut, can increase the frictional force of expansion sleeve and body of wall inwall, increases fixed effect of the present invention.
The present invention is particularly useful for adopting the building of hollow brick.
The present invention compared with prior art has tangible beneficial effect: expansion effect is better, fastening force is strong, good reliability, installation are quick and convenient, be convenient to remove, reusable.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Label is among the figure: 1, the body of bolt; 2, expansion sleeve; 3, nut; 4, plain washer; 5, slotted eye; 6, strip jut; 7, groove; 8, nail; 9, packing ring.
Embodiment
Referring to accompanying drawing 1; The present embodiment EXPANSION ANCHOR BOLTS; Comprise the body of bolt 1, expansion sleeve 2 and packing ring 9; The terminus inner of described expansion sleeve 2 is connected with the nut 3 that matches with the body of bolt 1, and the middle part of described expansion sleeve 2 is provided with five slotted eyes 5 along axial direction, and the middle part of described slotted eye 5 is expanded to both sides and is provided with groove 7; The other end of described expansion sleeve 2 is connected with plain washer 4, and described plain washer 4 is provided with nail 8 corresponding to the face of expansion sleeve 2; Described slotted eye 5 is symmetrical distribution; The outer surface of described expansion sleeve 2 is provided with strip jut 6.
When nut 3 is locked with the body of bolt 1; Expansion sleeve 2 is under the effect of axial compression power, and its weakness produces radial displacement immediately, because expansion sleeve 2 inwalls receive the obstruction of the body of bolt 1; Expansion sleeve 2 can only outwards be expanded, and forms drum shape until reaching the fixing purpose of swelling.
When removing EXPANSION ANCHOR BOLTS, then after unclamping, take out the body of bolt 1, firmly outwards act on plain washer 4, the expansion sleeve 2 that has been expanded into cydariform dwindles immediately, can take out expansion sleeve 2.
