Abstract
An easily detachable expanding screw joint is composed of screw bolt, expanding tube made of metal, plastics, rubber, or their mixture, and nut. It features that said expanding tube has a flange, so it can not be fully embedded in the hole on building, resulting in easily detaching it.
Description
The invention belongs to fastening connection piece:
Setscrew in the present fastening connection piece, its expansion tube does not protrude the edge, expansion tube all enters in the hole in use, just can not setscrew be taken out by bolt or by other instrument, therefore on the surface layer of many buildings, residual unnecessary setscrew had both caused waste, influence the attractive in appearance of building again, also may injure the person simultaneously even become the serious hidden danger of accident.
Purpose of the present invention is to avoid the deficiency in the above-mentioned technology, provides a kind of expansion tube pin structure that has, simple load and unload easily dismounting expansion thread connector.
The present invention reaches with following measure:
Easily dismounting expansion thread connector mainly is made of countersunk screw (1), expansion tube nail (2), nut (4).Wherein expansion tube nail (2) can adopt metal, plastics, rubber, asbestos, carbon element and some material mixing manufactures, the unexpansive end of expansion tube nail has the protrusion edge of outside bending, unexpansive end comprises the middle slightly position near non-opening end, protrudes the edge and comprises some non-coherent plush coppers or movable bolt.
When expansion tube nail (2) is made by hard materials such as metals, its inflating end has some longitudinal openings, and at the outwards protrusion edge of bending of the suspension of unexpansive opening end, can form with plain washer pressing that is complementary or spiral shell knot by common expansion tube, but and suitable rubber or the rubber and plastic waterproof ring (5) of suit.
When expansion tube nail (2) is made by soft materials such as rubber or rubber composites, its inflating end can not have longitudinal opening, and the suspension at unexpansive end is protruded under the edge with outwards bending, and can add serial connection and follow closely the ordinary rigid packing ring that (2) are complementary with soft expansion tube.
Expansion tube nail (2) outer wall can present coarse non skid mattings such as pit shape, reticulate pattern, shape of threads, and its inwall can have the threaded horizontal inner bending boss that matches, and is more firm to guarantee easily dismounting expansion thread connector.
The inside and outside tube wall of expansion tube nail (2) can have some vertical boss that are the pin key shape, also can make it not only more firmly solid, and have variation in vertically presenting other shape that thickness differs.Its tube wall also can be a kind of structure that contains double-deck cellular muscles and bones clearance hole.
All kinds of countersunk head shape bolts (1) that the expansion tube of easily dismounting expansion thread connector nail (2) can be complementary with common setscrew and nut (4) are gone here and there mutually and are spirally connected, on the internal thread wall of this nut, or the following Transverse plane of this nut can be inlayed rubber or plastic cement waterproof ring (5).
In addition, all kinds of bolts (1) that the expansion tube of easily dismounting expansion thread connector nail (2) also can be complementary with the regular screw threads link and convex pin taper nut (4) are gone here and there mutually and are spirally connected, Transverse plane under this bolt head, or on the screw rod wall under this bolt head, can inlay rubber or plastic cement waterproof ring (5).
When nut of easily dismounting expansion thread connector (4) or bolt (1) are inlayed rubber or plastic cement waterproof ring (5), can avoid its rust corrosion to guarantee its working life.
Easily dismounting expansion thread connector can be on demand, be combined into current version and special type, among special type, main its different structure that relies on comes by diplopore pipe clamp (6) or single hole pipe clamp (6) and rail pressing plate (7), and rag iron spring (8), packing ring (3) wait other fastening piece annex to reach its professional purpose.
The present invention has the following advantages than prior art:
1, the expansion tube nail can utilize the protrusion edge freely to remove and install in use.
2, can not remain on the building, the hole of building can in time be repaired.
3, can use repeatedly, can not become the obstacle on the building, eliminate accident potential.
Description of drawings is as follows:
Accompanying drawing 3 is a kind of schematic representation that can follow closely the hook countersunk head shape bolt (1) that (2) be complementary with expansion tube.
Accompanying drawing 4 is schematic representation of a kind of diplopore pipe clamp (6) that can be complementary with easily dismounting expansion thread connector.This diplopore pipe clamp (6) can adopt nonmetal hard material or the soft material of waiting to make, and the size shape in its two holes has various ways.
Accompanying drawing 5 is schematic representation of a kind of single hole pipe clamp (6) that can be complementary with easily dismounting expansion thread connector.
Accompanying drawing 6 is schematic representation of a kind of rail pressing plate (7) that can be complementary with easily dismounting expansion thread connector.
Accompanying drawing 7 be a kind of can with easily dismounting expansion thread connector, the schematic representation of the rag iron spring (8) that rail pressing plate (7) is complementary.
The diplopore pipe clamp (6) of accompanying drawing 4---accompanying drawing 7, single hole pipe clamp (6), rail pressing plate (7), rag iron spring (8) they are the special annexes of easily dismounting expansion thread connector, many things can be complementary with easily dismounting expansion thread connector by corresponding annex, make it obtain optimal fixation.
The invention will be further described below in conjunction with accompanying drawing:
Countersunk screw that accompanying drawing 1 runs through mutually (1) and expansion tube nail (2) major part in use are bumped in the hole of building, the suspension of having only expansion tube nail is with the threaded end head of the protrusion edge of outwards bending and countersunk screw and nut is protruding is exposed at outside the hole, can inwardly deeply make the soft easy contraction that become of the inflating end of expansion tube nail by countersunk screw after the use, then by taking out the expansion tube nail earlier so that easily dismounting expansion thread connector is whole takes out.
