Description
Technical field
The present invention relates to fastener, specifically oscillating rod type hollow brick hangs foot expansion bolt.
Background technology
In existing skyscraper, hollow brick is mostly used greatly and is built into wall, and in small sized multiple story building, cored slab work is mostly used greatly
For floor, when having finishing, the objects such as some household electrical appliances or ornament need to be filled by being commonly encountered on the wall being built by hollow brick or on cored slab
The case where product, can directly hang up, but when hanging up heavier article small-sized light and handy article using steel nail, steel nail
Bearing capacity is too small, it is clear that cannot use, existing method is hung up using general expansion bolt mostly, but due to hollow brick or sky
The wall thickness of core is relatively thin, and when in use, the swollen cylinder of expansion bolt is difficult distending, therefore loose phenomenon often occurs, therefore this mode
It is dangerous there are larger security risk.
Invention content
It is an object of the invention to provide a kind of structure novel, be connected firmly, stability is high, it is safe and reliable, easy to use,
Oscillating rod type hollow brick at low cost, with long service life hangs foot bolt.
In order to achieve the above objectives, the present invention include screw rod, nut, spring washer, plain washer, expansion cylinder, sliding block, swing rod and
Shaft is equipped with external screw thread on the outer round surface on the screw rod top, is equipped with guide post at the middle part of the screw rod, and in the spiral shell
The lower part of bar is equipped with swing rod, is equipped with flat nick on the centering block seat, the lower part of the expansion cylinder equipped with several be open to
Under the groove of the notch, the sliding block is compound cone broad in the middle small in ends, and the top of the sliding block is equipped with the conical surface, and in the cunning
The lower part of block is equipped with inverted cone surface, and the upper end of the swing rod is equipped with angle, and the swing rod is connect by shaft with swing rod, the cunning
Block, expansion cylinder, plain washer, spring washer and nut successively from the bottom to top be loaded on screw rod on, the back taper of the sliding block downwards and
Top loaded on swing rod, the lower section of the groove of the notch of the conical surface loaded on expansion cylinder lower part of the sliding block.
The present invention is as a result of by screw rod, nut, spring washer, plain washer, expansion cylinder, sliding block, swing rod and shaft group
At structure can swing rod first be put into the position with the axis parallel of screw rod, then, by it after such structure
It is inserted into the hole of hollow brick or cored slab, when swing rod enters the hollow area of hollow brick or cored slab, slowly tightens nut,
During tightening nut, swing rod is pushed to rotate clockwise around the shaft by the inverted cone surface of sliding block, when swing rod goes to horizontal position
When setting, sliding block no longer moves, and continues to tighten nut, and screw rod is slightly displaced outwardly, and when going to horizontal position due to swing rod, swing rod will block
In hole edge, screw rod cannot continue to extract outward, at this moment, by the conical surface of sliding block by the expansion cylinder distending equipped with the groove of the notch, from
And tension force is generated, it is remarkably improved the reliability and stability of connection.The inventive structure is novel, is connected firmly, and stability is high,
Securely and reliably, easy to use, at low cost, service life is long.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is that the swing rod in Fig. 1 rotates clockwise the application schematic diagram after 90 degree.
Specific implementation mode
