Abstract
The utility model discloses a novel expansion bolt, which comprises a bolt, an expansion casing pipe, a flat washer and a spring washer. The novel expansion bolt is characterized by comprising a round-table-shaped expansion nut. The outer diameter of the bigger end of the round-table-shaped expansion nut is bigger than the outer diameter of the expansion casing pipe, the outer diameter of the smaller end of the round-table-shaped expansion nut is smaller than the inner diameter of the expansion casing pipe and the smaller end of the round-table-shaped expansion nut is inserted in the notch end of the expansion casing pipe, and the internal thread of the round-table-shaped expansion nut is matched with the thread of the bolt. In use, only a screw cap is exposed on a wall or the ground, thereby bringing convenience and having attractive appearance; the bolt is easy to remove, and removing the bolt does not damage the wall or the ground; the bolt can be used repeatedly, objects can be reinstalled conveniently, and therefore the bolt is durable and economical.
Description
Technical field
The utility model relates to a kind of link that installs and fixes, a kind of specifically upset bolt.
Background technique
EXPANSION ANCHOR BOLTS is that people are fixed on body of wall or ground a kind of link commonly used with object in producing, living, present employed EXPANSION ANCHOR BOLTS is mainly by bolt and nut engaged and expansion sleeve are formed with it, wherein the end of bolt is a frustoconic shape ailhead shape, expansion sleeve is enclosed within the middle of the bolt, its end near the frustoconic shape ailhead has four vertical notches, notch is about and is 1/3rd of expansion sleeve, becomes four expansion muscle; Nut is positioned at the other end of bolt.In the use, at first on body of wall or ground, bore the mounting hole that a diameter is slightly larger than the frustoconic shape ailhead, EXPANSION ANCHOR BOLTS is inserted wherein (the frustoconic shape ailhead is interior), place object, fastening nut, the frustoconic shape ailhead is pressed in the expansion sleeve from small end to big end, forces the tapered dilatancy of expansion muscle, swelling is fixed object in mounting hole.But, the expansion sleeve distortion of this EXPANSION ANCHOR BOLTS can not change because of external force disappears, all the time tightly be stuck in the hole, want to take out very difficulty of EXPANSION ANCHOR BOLTS, and need to change the former object that fixes in the daily life, after object is removed, bolt is exposed at outside body of wall or the ground more, both inconvenience was not attractive in appearance yet, had to damage body of wall or floor surface for removing EXPANSION ANCHOR BOLTS sometimes, caused damage to the owner.
Summary of the invention
The purpose of this utility model is the non-disconnectable defective of removing of EXPANSION ANCHOR BOLTS that overcomes prior art, provides a kind of and not only can firmly fix but also can remove easily and reusable upset bolt, and the dismounting rate can reach 100%.
For solving the deficiency that prior art exists, the utility model adopts following technical proposals:
A kind of upset bolt of the utility model comprises bolt, expansion sleeve, flat gasket and compression spring, it is characterized in that: it also has a frustoconic shape swelling nut, the big end external diameter of described frustoconic shape swelling nut is greater than the expansion sleeve external diameter, the small end external diameter is less than the expansion sleeve internal diameter and be plugged in the notch end of expansion sleeve, and the internal thread and the bolt thread of frustoconic shape swelling nut match.
Description of drawings
Fig. 1 is the structural representation of a kind of upset bolt of the utility model.
Among Fig. 1: 1, frustoconic shape swelling nut, 2, bolt, 3, expansion sleeve, 4, flat gasket, 5, compression spring.
Embodiment
Below in conjunction with accompanying drawing and embodiment a kind of upset bolt of the utility model is further specified.
In Fig. 1, bolt 2 length are 6 centimetres to 10 centimetres, the screw thread of M10 is set on its 1/2nd screw rod, expansion sleeve 3 length are 5 centimetres to 9 centimetres, internal diameter is 10.4 millimeters, external diameter is 12 millimeters, and on expansion sleeve 3, evenly open and cut four the 2 centimetres vertical notches to 4 centimeter length, as the expansion muscle, expansion sleeve 3 is placed on the bolt 2, vertically notch is positioned at frustoconic shape swelling nut 1 end, frustoconic shape swelling nut 1 length is 1.0 centimetres to 1.5 centimetres, and its Outside diameter is 12.4 millimeters, and end diameter is 10.2 millimeters, frustoconic shape swelling nut 1 is shaped on the internal thread of M10, and flat gasket 4 and compression spring 5 adopt standard piece.
When object is installed, earlier on body of wall or ground, make a call to a hole that is slightly larger than frustoconic shape swelling nut 1 external diameter with percussion drill, the screw rod of the degree of depth and bolt 2 matches, and then, sets object, EXPANSION ANCHOR BOLTS is inserted (frustoconic shape swelling nut 1 is in the hole) in the hole, turn the nut on the bolt, make frustoconic shape swelling nut 1 move, the outside distending of vertical notch of expansion sleeve 3 to the nut direction, stretching arrives the purpose of fixed object in the hole; If need to remove object, only need loosen nut to get final product until taking out bolt 2, expansion sleeve 3 swelling all the time is in the hole, and frustoconic shape swelling nut 1 is also stayed in the hole, can be again to reinstall object convenience is provided.
In order to make frustoconic shape swelling nut 1 can anti-slip tank be set on its surface along with bolt rotates.
Adopt a kind of upset bolt of the utility model, be exposed at the nut that has only outside body of wall or the ground, not only convenient but also attractive in appearance, save trouble very much when removing bolt, can not destroy body of wall or ground, it is convenient to reinstall object, reusable, good economy performance durable in use.
Claims (2)
1. upset bolt, comprise bolt (2), expansion sleeve (3), flat gasket (4) and compression spring (5), it is characterized in that: it also has a frustoconic shape swelling nut (1), described frustoconic shape swelling nut (1) holds external diameter greater than expansion sleeve (3) external diameter greatly, the small end external diameter is less than expansion sleeve (3) internal diameter and be plugged in the notch end of expansion sleeve (3), and the internal thread and the bolt thread of frustoconic shape swelling nut (1) match.
2. according to the said a kind of upset bolt of claim 1, it is characterized in that: the surface at frustoconic shape swelling nut (1) is provided with anti-slip tank.
