Description
Technical field
This utility model belongs to technical field of fastening, particularly relates to a kind of casing expandable spiral shell
Bolt assembly.
Background technology
Expansion bolt, be pipeline is propped up/hangs/bracket or equipment is fixing on the wall, on floor,
A kind of special thread connector used on post.
Such as, Chinese patent discloses a kind of expansion bolt, application number
[201220561622.8], its expanding screw that only just can take out completely from one end of bolt hole
Bolt, described expansion bolt includes screw rod, expansion sleeve and nut, packing ring, one end of screw rod
For the external thread section with nut screw connection, the other end of screw rod is and expansion sleeve cone match
Round platform, is provided with sleeve pipe at screw jacket, and the two ends of sleeve pipe bear against in packing ring and expansion
Putting, during expansion sleeve distending, the end face of expansion sleeve is beyond the end face of screw rod, and its connection can
Lean on, detachably, be especially suitable for being rigidly connected temporarily.
Although above-mentioned scheme has many advantages, but, this bolt its most at least
There is techniques below problem: after expansion sleeve is extruded expansion, its outer wall forms taper and connects
Contacting surface, or there is the caducous technical problem of appearance, secondly, expansion sleeve is in expansion process
In be susceptible to circumferentially rotate, poor practicability.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of design is more reasonable,
It can be avoided that come off and casing expandable bolt assembly that practicality is higher.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: this sleeve pipe
Expansion bolt assembly includes bolt, is cased with pad, expansion tube and circle on bolt successively
Nut, is provided with the bar hole of your distribution of some even circumferentials, adjacent in the middle part of expansion tube
Two bar holes between be provided with outwardly strip bulge, described expansion tube one end
It is resisted against on pad, is provided with some with described bar hole at the expansion tube other end and connects one by one
Logical fluting, tapered and the little head end of this round nut the external diameter of described round nut is little
In the internal diameter of expansion tube, it is provided with the distribution of some even circumferentials at round nut little head end outer wall
Axial projection, be provided with circumferential positioning structure between described pad and expansion tube.
In above-mentioned casing expandable bolt assembly, described circumferential positioning structure is concavo-convex
Fit structure.
In above-mentioned casing expandable bolt assembly, described circumferential positioning structure include to
A few breach being arranged on inside pad, at one end tool that expansion tube is resisted against on pad
Have and can insert in the projection in described breach one by one.
In above-mentioned casing expandable bolt assembly, described breach quantity is three and circle
Week is uniformly distributed, and described protruding quantity is three and even circumferential distribution, and described lacks
Mouth is connected one by one with projection.
In above-mentioned casing expandable bolt assembly, described expansion tube and projection are linked as one
Body formula structure.
In above-mentioned casing expandable bolt assembly, described bolt is hexagon-headed bolt.
Compared with prior art, the advantage of this casing expandable bolt assembly is: 1, set
It is more reasonable to count, it is possible to increase the structure fixing after installation, it is to avoid obscission.2、
Simple in construction and easily fabricated.3, service life is long.4, circumferentially positioned owing to being provided with
Structure, it is possible to significantly reducing and circumferentially rotate, practicality is higher.
Accompanying drawing explanation
Fig. 1 is the detonation configuration schematic diagram that this utility model provides.
Fig. 2 is the circumferential positioning structure schematic diagram that this utility model provides.
In figure, bolt 1, pad 2, breach 21, expansion tube 3, bar hole 31, bar
Shape projection 32, fluting 33, projection 34, round nut 4, axial projection 41.
Detailed description of the invention
With detailed description of the invention the present invention done further details of theory below in conjunction with the accompanying drawings
Bright.
As shown in Figure 1-2, this casing expandable bolt assembly includes that bolt 1, bolt 1 are
Hexagon-headed bolt.Bolt 1 is cased with pad 2, expansion tube 3 and round nut 4 successively,
The bar hole 31 of your distribution of some even circumferentials it is provided with, adjacent in the middle part of expansion tube 3
Outwardly strip bulge 32 it is provided with, in expansion tube 3 between two bar holes 31
Wall is provided with and described strip bulge 32 strip groove one to one.Expansion tube 3 is by gold
Belong to plate stamping bending to make.
Expansion tube 3 one end is resisted against on pad 2, sets between pad 2 and expansion tube 3
There is circumferential positioning structure.Specifically, circumferential positioning structure here is concave-convex fit structure.
Circumferential positioning structure includes that at least one is arranged on the breach 21 inside pad 2, is expanding
One end that pipe 3 is resisted against on pad 2 has and can insert in one by one in described breach 21
Protruding 34.Expansion tube 3 is connected as a single entity structure with protruding 34.
Secondly, breach 21 quantity is three and even circumferential distribution, described projection 34
Quantity is three and even circumferential distribution, and described breach 21 coordinates one by one with protruding 34
Connect.
Opening that expansion tube 3 other end is provided with that some with described bar hole 31 connects one by one
Groove 33, tapered and this little head end of round nut 4 the external diameter of described round nut 4 is little
In the internal diameter of expansion tube 3, it is provided with some even circumferentials at round nut 4 little head end outer wall
The axial projection 41 of distribution.
In the present embodiment, when bolt 1 rotates, round nut 4 extrudes described expansion
