Abstract
The utility model discloses a self fixing connection bolt, which is characterized in that one end of the inner wall of an outer sleeve is provided with internal thread, and the other end is provided with a taper hole; one end of bolts in the outer sleeve is provided with screw thread, and the other end forms a positive tapered body; one end of the outer wall provided with the internal thread of the outer sleeve is provided with a connecting body, and the middle part of the outer sleeve is provided with a flat ring body; the outer wall at one end of the taper hole is provided with an anchor hook, the other end is provided with a connecting body, and the connecting body is connecting thread or a connecting ring or a connecting hook. The self fixing connection bolt has the advantages that the structure is simple, the reliability for installing the utility model on a wall body is good; the anchor hook outside the taper hole is tightly pricked into the wall body, making the self fixing connection bolt and the wall body basically connected into a whole, and the reliability for fixing an object is good; when the utility model is used, the surface of the wall body is beautiful and clean.
Description
It is particularly a kind of from being solidly connected bolt that the utility model relates to a kind of connection.
The EXPANSION ANCHOR BOLTS that fixed object uses on body of wall in the prior art has a bolt, the outer overcoat that connects of bolt, one end of bolt has screw thread, on screw thread, be connected with nut, the other end is a polished rod, and the chap gradually to the end from the middle part, is an inverted cone, the internal diameter of overcoat is less than the external diameter of inverted cone part, and overcoat has opening longitudinally near an end of inverted cone.During use, on body of wall, make a call to a hole, an end that EXPANSION ANCHOR BOLTS is had inverted cone together is inserted in the hole together with overcoat, fastening nut, at this moment bolt is pulled out and overcoat is left in the hole, because the other end of bolt is an inverted cone, when inverted cone moves outward, the longitudinal opening that puts is outward strutted, and be compressed on the hole wall, at this moment can connect object on the bolt that EXPANSION ANCHOR BOLTS exposes.This bolt is to utilize inverted cone extruding overcoat, and the frictional force between increase overcoat and the body of wall hole wall reaches the purpose of fixed object, the poor reliability of fixed object on body of wall.
The purpose of this utility model be to provide a kind of on body of wall the fixed object good reliability be solidly connected bolt certainly.
The scheme that realizes the utility model purpose is: the end at outer casing inner wall has internal thread; The other end has a tapered hole, and bolt one end in overcoat has screw thread, and the other end is a right circular cone, at the female end of outer casing outer wall connecting body is arranged.
There is flat ring body at the middle part of overcoat, on the outer wall of tapered hole one end grasp is arranged, and the other end has connecting body, is connected with capsule in the front portion of tapered hole.
Connecting body is a connecting thread or for connecting ring or for butt hook.
Owing to adopt such scheme, in overcoat, be connected with bolt, there is the flat ring body greater than overcoat at the middle part, to be solidly connected bolt certainly when being inserted in the body of wall hole, flat ring body is shut the aperture of body of wall, and only connecting body is exposed to the body of wall outside, makes surface of wall attractive in appearance, clean during use; End at the overcoat tapered hole has opening longitudinally, turn bolt, the right circular cone of bolt front end with the tapered hole of overcoat longitudinally opening strut, grasp outside tapered hole penetrates in the body of wall tightly, when clamping bolt, after the capsule that the tip of bolt front end will be connected the tapered hole front portion punctures, after glue in the capsule flows out, to be solidly connected bolt certainly and be bonded as one firmly, the connection reliability that is solidly connected bolt and body of wall certainly is good, has reached the purpose of this utility model.It is simple that this is solidly connected stud structure certainly, is installed in good reliability on the body of wall, and the outer grasp of tapered hole penetrates in the body of wall tightly, make from being solidly connected bolt and body of wall connects as one substantially, promptly, make surface of wall attractive in appearance, clean during use, applied range from the good reliability that is solidly connected the bolt fixed object.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Fig. 1 is the utility model first example structure figure.
Fig. 2 is the utility model second example structure figure.
Fig. 3 is the utility model the 3rd example structure figure.
Embodiment 1: being solidly connected bolt certainly has a bolt 4, and the outer overcoats 2 that connect of bolt 4 have internal thread at an end of overcoat 2 inwalls; The other end has a tapered hole, and bolt 4 one ends in overcoat 2 have screw thread, and this screw thread matches with the internal thread of overcoat 2 inwalls, the other end is a right circular cone, at the female end of overcoat 2 outer walls connecting body 3 is arranged, and connecting body 3 is a screw thread, be connecting thread, flat ring body 5 is arranged at the middle part of overcoat 2; End at tapered hole has grasp 1; The tapered hole internal diameter of overcoat 2 is less than the external diameter of right circular cone, and overcoat 2 has opening longitudinally near an end of tapered hole.During use, on body of wall, make a call to a hole, to be solidly connected bolt certainly is inserted in the hole, until being solidly connected certainly till flat ring body 5 on the bolt covers the hole mouth, block flat ring portion with spanner, turn bolt 4, the right circular cone that makes bolt 4 front portions with the overcoat tapered hole longitudinally opening strut, the grasp 1 of overcoat 2 outsides just penetrates to hole wall, is fixed in the hole firmly.
Embodiment 2: be connected with capsule 7 at the tapered hole front end, the right circular cone of bolt 4 front ends extends forward becomes a taper, when turning bolt 4, bolt 4 can puncture capsule 7, glue in the capsule 7 is flowed out, the overcoat 2 that will be solidly connected bolt certainly is bonded as one with body of wall 6 holes, and the connecting body 3 before the overcoat 2 is a ring, i.e. connecting ring.Other and embodiment 1 omit together.
Embodiment 3: the connecting body 3 of overcoat 2 front ends is a hook, i.e. butt hook.Other and embodiment 1 omit together.
Claims (3)
1, a kind of have a bolt from being solidly connected bolt, and bolt connects an overcoat outward, and an end of overcoat has opening longitudinally, it is characterized in that: the end at outer casing inner wall has internal thread; The other end has a tapered hole, and bolt one end in overcoat has screw thread, and the other end is a right circular cone, at the female end of outer casing outer wall connecting body is arranged.
2, according to claim 1 it is characterized in that: there is flat ring body at the middle part of overcoat, on the outer wall of tapered hole one end grasp is arranged from being solidly connected bolt, and the other end has connecting body, is connected with capsule in the front portion of tapered hole.
