Abstract
The invention relates to a spring cushion expansion type easy-disassembling strengthening expansion bolt. The bolt is cylindrical, one end of the bolt is provided with a thread used for fastening a nut, while the other end is provided with a cone table; a spring cushion is circular and is provided with an opening; the cross section of the spring cushion is a trapezoid; a gasket is circular and is not provided with an opening, and the cross section of the gasket is a trapezoid; a sealing spacer has a wafer structure; and the middle hole sizes of the spring cushion, the gasket and the sealing spacer are slightly larger than the diameter of the cylindrical part of the bolt and the spring cushion, the gasket and the sealing spacer can be sleeved into the bolt and can flexibly move. After the spring cushion expansion type easy-disassembling strengthening expansion bolt is arranged in a mounting hole, the sealing spacer is aligned to the mounting hole surface, the nut is rotated, the bolt is strained, and the bolt, the gasket and the sealing spacer commonly act to make the spring cushion expanded and closely combined with inner walls of the mounting hole. Because the number of the wall combination surfaces is not only one, the acting force born by the bolt is greatly larger than that of a common expansion bolt. When the bolt needs to be disassembled, the nut is loosened, and the spring cushion is contracted to separate from the four walls of the mounting hole, so that the bolt can be conveniently taken out.
Description
Technical field
The present invention relates to a kind of spring cushion expansion type easy-disassembling strengthening expansion bolt, belong to the material field of using that installs and fixes.
Background technique
Known EXPANSION ANCHOR BOLTS is made of metal expansion pipe, bolt, packing ring and nut.One end of its bolt is plaing at the bottom of the bloated circular cone that acts on of holder of circular cone sample, and the diameter at the bottom of the circular cone is identical with the metal expansion pipe diameter.The other end of bolt is the standard double-screw bolt.One end of metal expansion pipe has a plurality of opening slots, the end that opening slot arranged facing to the circular cone on the bolt at the bottom of, be enclosed within on the bolt, nut is spun on the bolt, the bloated cap of the holder of its circular cone sample of tightening nut can be wedged the cavity of the expansion tube of opening slot one end, is fastened in the boring of object thereby support is bloated.The problem that occurs during such EXPANSION ANCHOR BOLTS is used has: 1, an expansion Point of Strength is just arranged in its end, and the solid weak effect of support swelling, and also the bolt of the nut the other end is prone to lateral deviation.2, can not restore to the original state after the bending deflection of expansion of metal casing expandable because of the disappearance of external force.Because metal expansion pipe is connected in the mounting hole, and often do not expose outside the mounting hole, take out EXPANSION ANCHOR BOLTS, can only spur the swell fixture or the frustoconic shape nut that have the frustoconic shape ailhead by force, described like this expansion sleeve can further expand and be connected in the mounting hole tightly.In this case, if continue to increase pulling force, promptly allow to pull out reluctantly also and can damage body of wall or ground.And the expansion sleeve after taking out is out of shape, and is difficult to reuse.We often run into and are installed in the body of wall or needs dismounting that hardened ground is interior and the EXPANSION ANCHOR BOLTS that is difficult to remove.These EXPANSION ANCHOR BOLTS that protrude in body of wall or hardened ground have caused a lot of inconvenience to us, have a strong impact on attractive in appearance.
Summary of the invention
In order to overcome existing EXPANSION ANCHOR BOLTS structure deficiency in this respect, the invention provides a kind of spring cushion expansion type easy-disassembling strengthening expansion bolt.
The scheme that deficiency adopted that the present invention solves the EXPANSION ANCHOR BOLTS structure is: a kind of spring cushion expansion type easy-disassembling strengthening expansion bolt, comprise bolt, spring pad, packing ring, seal gasket and nut, described bolt is a cylindrical body, one end has and is used for the screw thread that tightening nut is used, the other end is a circular cone, and the section of spring pad is trapezoidal; Spring pad is circular, and an opening is arranged.Packing ring is a circular gasket, does not have opening, and the section of packing ring is trapezoidal; Seal gasket is a wafer architecture, and the intermediate pore size of spring pad, packing ring, seal gasket is transition fit than the column part slightly larger in diameter of bolt, is inserted in the bolt also can move flexibly.
Benefit of the present invention is that after spring cushion expansion type easy-disassembling strengthening expansion bolt placed in the mounting hole, seal gasket 4 was concordant with the mounting hole face, tightening nut 5, turnbuckle 1, bolt 1, packing ring 3, seal gasket 4 actings in conjunction, make spring pad 2 distendings, combine closely with wall in the mounting hole.Because with the more than place of wall junction plane, so the active force that can bear is more many greatly than common EXPANSION ANCHOR BOLTS.When needs are dismantled, unclamp nut 5, spring pad 2 shrinks, and throws off with wall in the mounting hole, can take out easily.
Description of drawings
Fig. 1 is the sectional drawing of this spring cushion expansion type easy-disassembling strengthening expansion bolt;
Fig. 2 is the front view of spring pad 2, packing ring 3.
Below in conjunction with drawings and Examples model utility is further specified.
Embodiment
Embodiment 1:
Constitute by bolt 1, spring pad 2, packing ring 3, seal gasket 4 and nut 5.Referring to shown in Figure 1.Described bolt 1 is a cylindrical body, and an end has the screw thread that is used for tightening nut 5 usefulness, and the other end is a circular cone, and the trapezoidal side angle of the section angle of its circular cone and the section of spring pad 2 is suitable.The sectional view of spring pad 2 such as Fig. 1 are for trapezoidal; Front view is circular gasket as shown in Figure 2, and an opening is arranged, so that stressed expansion.The sectional view of packing ring 3 such as Fig. 1 are for trapezoidal; Front view is circular gasket as shown in Figure 2, does not have opening, and the trapezoidal side angle of the side angle that the section of packing ring 3 is trapezoidal and the section of spring pad 2 is suitable.Seal gasket 4 is a wafer architecture, and sectional view is seen Fig. 1, and the one side of seal gasket 4 is that the plane contacts with tightening nut 5, and its another side is that the trapezoidal side angle of inclined-plane and spring pad 2 is suitable.Wherein, the intermediate pore size of spring pad 2, packing ring 3, seal gasket 4 slightly than the column part slightly larger in diameter of bolt 1 some so that can be inserted in the bolt 1 and can move flexibly.
Fig. 1 is a schematic representation.Because spring pad 2, packing ring 3 are movable parts, increase along with bolt 1 length of spring cushion expansion type easy-disassembling strengthening expansion bolt, the number of used spring pad 2, packing ring 3 also can increase simultaneously, and the spring cushion expansion type easy-disassembling strengthening expansion bolt load also can increase like this.Certainly the diameter of bolt 1 also can change along with needs.
Embodiment 2:
The sectional drawing of spring cushion expansion type easy-disassembling strengthening expansion bolt is made of bolt 1, spring pad 2, packing ring 3, seal gasket 4 and nut 5 as shown in Figure 1, and packing ring 3 is in the centre of two spring pads 2.
The boring of earlier spring cushion expansion type easy-disassembling strengthening expansion bolt being put into object during use, seal gasket 4 is concordant with the mounting hole face, axial tension effect during tightening nut 5, under the circular cone acting in conjunction of packing ring 3, seal gasket 4 and bolt 1, spring pad 2 distendings, combine closely with wall in the mounting hole, like this because a plurality of spring pads 2 (one group of pair that expands of spring pad 2 and packing ring 3 compositions, can adopt expansion pair greater than two groups) distending combines with wall, its fastness and stress effect are good, and bolt is difficult for loosening or lateral deviation.
Embodiment 3:
Mounted spring cushion expansion type easy-disassembling strengthening expansion bolt when needs are dismantled, unclamps nut 5, and spring pad 2 shrinks, and throws off with wall in the mounting hole, can take out easily, so that reuse.
