Background technique
Expansion bolt is that one kind pipeline branch/hang/bracket or equipment is fixed on the wall, on floor, used on column is special
Threaded connector.In use, the hole of corresponding size must first be drilled out with electric impact drill (hammer) on fixed body, then bolt, tube expansion
In load hole, tightening nut can make that bolt, tube expansion, swelling is integrally formed between installation part and fixed body.
Dilatable after tightening, bolt tail has a major part, the outer surface cover one of the bolt circle more slightly larger than the diameter of bolt
Pipe, the tail portion road part You Ji opening, after bolt is tightened, the tail portion of major part is just brought to inside the pipe of opening,
Pipe punching is big, achievees the purpose that expansion, and then bolt is fixed on ground or wall, achievees the purpose that take root.
The fixation principle of setscrew: the fixation of setscrew is promoting expansion to generate friction using shape gradient is taken along to hold
Power is wrapped up in, fixed effect is reached.One, screw is screw thread, and one has vertebra degree.Outer one sheetmetal of bread, iron sheet cylinder half have several cut
Mouthful, they are filled in together in the hole accomplished fluently on wall, then split nut, nut pulls outward screw, and vertebra degree is pulled in sheetmetal circle
Cylinder, sheetmetal cylinder are then tightly secured on wall by spreading, are generally used for protective fence, rain cover, air-conditioning etc. in materials such as cement, bricks
Fastening on material.But its fixation is not very reliable, if load has significant shock, it may occur however that loosen, therefore do not recommend
For installing ceiling fan etc..The principle of expansion bolt is Kong Zhonghou expansion bolt got on ground or metope, is screwed up with a wrench
Nut on expansion bolt, bolt walk toward outside, and the metallic sheath of outside is motionless, and then, the major part under bolt is just metal
Spreading is covered, makes the entire hole of its overflow, at this point, expansion bolt just can't pump out.The effect of expansion bolt be for fixing, it is existing
Expansion bolt be chiefly used in concrete wall, and the metallic sheath of expansion bolt can be close to concrete walls when rigid installation, but
Be concrete as time goes by can weathering, be close to reduce between expansion bolt and concrete wall, cannot achieve fixation
Effect, need to punch again replacement or give up original expansion bolt, the expansion bolt of larger diameter is installed, is not only caused
The waste of expansion bolt, it is also necessary to put into a large amount of manpowers and periodic inspection and maintenance are carried out to the expansion bolt for entering wall, cause into
This promotion；And the stability of used expansion bolt can further decline, because metallic sheath had been inflated once,
Enter new hole in when, metallic sheath needs further expanded, and metallic sheath open it is larger after can be too long due to the arm of force
The friction between metallic sheath and hole wall is reduced, the straight line decline of firm performance is caused.
Summary of the invention
The present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide the expansion bolt that can be recycled and reuse.
The present invention is achieved through the following technical solutions:
The expansion bolt that can be recycled and reuse, including setscrew, hex nut, spring washer, large washer, gold
Belong to set, reversed support device, slide bushing assembly, the bottom of the setscrew is provided with expansion bolt and squeezes stake, the metallic sheath
It covers in the outside of the setscrew, the hex nut, spring washer, large washer are from top to bottom successively socketed in the expansion
The top of screw；The reversed support device includes reversely supporting stake, reverse thread, reversed nut and articulated mounting, described anti-
There are more to support stake, more reversed support stakes are evenly distributed on the middle part of the metallic sheath, the middle part setting of the metallic sheath
There are multiple gaps, gap matches one by one with reversed support stake；The bottom end of the reversed support stake is connected to sky by articulated mounting
The top of the lower end of gap, the reversed support stake is hanging；The reverse thread is positioned close to the setscrew of gap lower end
Surface, the reversed nut are connected on reverse thread；The rotation of the screw thread of the direction of rotation and hex nut of the reverse thread
Turn contrary；The reversed nut moves on reverse thread so that reversed nut and reversed support staking touching；The sliding sleeve
Component includes chain, sliding sleeve ontology, latch recess, locking projections, and setting is fluted in the middle part of the setscrew, and groove is in anti-
To the upside of screw thread；The sliding sleeve ontology clamp are in a groove；The inner surface of sliding sleeve ontology is arranged in the latch recess, described
The groove surfaces of setscrew are arranged in locking projections, and the latch recess is matched with locking projections, when setscrew locking turns
When dynamic, the sliding sleeve ontology and setscrew rotating Vortex simultaneously keep opposing stationary, described when setscrew is unlocked rotation
Sliding sleeve ontology does not rotate；Described chain one end is connected to the outer surface of sliding sleeve ontology, and the other end is connected in reversed support stake；Institute
State the quantity of chain and the quantity Matching of reversed support stake.
The fixation of existing expansion bolt is not very reliable, if load has significant shock, it may occur however that loosen；By swollen
The course of work of swollen bolt can easily show that the fixation of expansion bolt is unreliable: first burrow on wall, by expansion bolt
It is inserted into hole, after metallic sheath and hole wall relative securement, setscrew is rotated outward, the taper of setscrew is promoted to squeeze into gold
Belong in set, metallic sheath is forced to flex outward out, after metallic sheath trails, the edge of metallic sheath is contacted with hole wall, to play solid
Fixed effect.It can clearly be obtained from the above process, what existing expansion bolt relied solely on is the edge progress of metallic sheath
Fixed, when the carrier in hole wall weathering perhaps hole vibrates or expansion bolt is artificially shaken, expansion bolt can be easily
Be removed, lose fixed effect；And the stability of used expansion bolt can further decline, because metallic sheath is
It was inflated once, when entering in new hole, metallic sheath needs are further expanded, and after metallic sheath opening is larger
The friction between metallic sheath and hole wall can be reduced since the arm of force is too long, lead to the straight line decline of firm performance.
The present invention reinforces on the basis of the structure of existing expansion bolt and application method, beats on present carrier
Hole screws out setscrew after the present invention is relatively stable in the carrier outward, and the present invention is anti-in the setting of the middle part of setscrew
To screw thread, reversed nut is installed additional on reverse thread, gap is set on the metallic sheath on the outside of reverse thread, is arranged in gap
The bottom end in reversed support stake, the reversed bottom end for supporting stake and gap connects, reversed that stake is supported to fill gap；When setscrew to
When outer back-out, due to hex nut direction of rotation in the direction of rotation of reverse thread and setscrew on the contrary, so when swollen
When swollen screw screws out outward, reversed nut is gradually contacted with the bottom of reversed support stake, when reversed nut is by reversed support stake
Resistance after, static friction is formed between reversed nut and reversed support stake, at this point, setscrew continues to rotate, and reversed nut
It is static relative to reversed support stake under the driving of static friction, and be rotated up relative to reverse thread, with reversed spiral shell
The increase of mother's moving distance on setscrew, the pressure between reversed nut and reversed support stake can be stepped up；Reversed branch
The bottom of support stake, which receives, to upward pressure, and reversely supports between stake and metallic sheath hingedly, and the reversed top for supporting stake is hanging, then
Reversed support stake will be rotated around bottom junctions, and the reversed top for supporting stake is unfolded outward, reversed to support stake relative to swollen
Swollen screw inclination；Rotating outward for setscrew brings two variations, and a variation is the metallic sheath opening of metallic sheath lower end
Slot is softened, and the lower edge of metallic sheath is unfolded and contacts with hole wall；Another variation is exactly, reversed that stake is supported to strut outward, instead
It is contacted to the top of support stake with hole wall, since the direction for reversely supporting the direction of stake and expansion bolt to be detached from is on the contrary, thus
Expansion bolt can be made preferably to be fixed in the carrier；Even if carrier is the object for being easy weathering or generating deformation, as long as
Change the degree that setscrew screws out outward to change the degree that reversed support stake is opened, it will be able to according to the change of carrier hole wall
Shape and the hole wall for being preferably fixed on carrier suffers.
During setscrew screws out outward, due to the cooperation of latch recess and locking projections in slide bushing assembly,
It is the relationship not locked between latch recess and locking projections, then sliding sleeve ontology is not rotated with the rotation of setscrew, just
There are static friction between calculation sliding sleeve ontology and the groove of setscrew, also due to the connection of chain and reversed support stake prevents cunning
Set ontology is rotated with the rotation of setscrew；When needing to recycle the present invention, by setscrew to internal locking, expand at this time
The direction of rotation of screw on the contrary, and locking relation is formed between latch recess and locking projections, the rotation meeting of setscrew so that
Sliding sleeve ontology follows setscrew to make rotation in the same direction, since sliding sleeve ontology cannot be detached from the rotation of setscrew, then sliding sleeve sheet
Chain on body will and then be wrapped in the surface of sliding sleeve ontology, with the tightening of chain, chain will reversed support stake draw over to one's side to
In gap, then successfully reversely stake will be supported to recycle, and make reversely stake to be supported to lose reversely fixed effect, at this point, expansion bolt
It is only contacted between the edge of metallic sheath and hole wall, as long as expansion bolt is firmly pulled out outward, can easily recycle expansion
