Abstract
The utility model discloses a kind of quick locking, dismounting fastener, including cover tile (5), seat watt (6), pin (2), axis pin (3), clamp spring (4), screw rod (7), nut (8).Cover tile (5) is hinged with axis pin (3) with seat watt (6) one end, axis pin (3) clamp spring (4) retaining, other end seat watt (6), screw rod (7) end face double helix face are coupled fastening, above part forms fastener unit (1), is riveted between fastener unit with pin (2) hot pressing；Seat watt (6) and screw rod (7) respectively have at least one identical rotation direction, the end face helicoid of same-handed lift angle, this end face helical structure is special wedge structure.The utility model realizes that the self-locking of fastener Quick fastening and dismounting act using this special wedge structure, improves building scaffold lapping construction efficiency, mitigates worker's duplication of labour intensity.
Description
Technical field
A kind of quick locking, dismounting fastener are the utility model is related to, is mainly used for construction scaffold lapping.
Background technology
In building construction process, we can overlap, and scaffold is used to support, security protection etc. requires, indispensable in construction
Part is exactly fastener.Traditional scaffold clasp is to be acted with T-bolt, nut to realize that fastener clamps steel pipe, and builds and apply
Scaffold is overlapped during work can use the fasteners of thousands of quantity, and the bolt on fastener, which tightens, dismantle repetitive operation consumes
Substantial amounts of manpower, time.Period, I consulted the related achievement in research of Quick Release fastener, such as Patent No. 200920242849.4
A kind of " rapid locking fastener " patent, it is found that this utility model Quick Release fastener is unable to Quick Release, locking, analyzed from its content of the invention
Reason has at 2 points：One is that double helix face on the fastener body that coordinates with it of double helix face of lock shaft is oppositely oriented, similar rotation
It can not be assembled to inconsistent bolt and nut；The other is the thin structure in the big centre in lock shaft two leads to not dismount.To sum up
Described, the invention of this utility model is not carried out quick locking, dismounting purpose.
The content of the invention
The purpose of the present invention is design it is a kind of can manual quick locking, dismounting fastener, it is strong to reduce worker's work with this
Degree.The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of quick locking, dismounting fastener, including cover tile, seat watt, pin, axis pin, clamp spring, screw rod, nut, the cover tile
It is hinged with seat watt one end with axis pin, axis pin clamp spring retaining；The other end is coupled by seat watt, screw rod；The seat watt and screw rod are each
There are at least one same-handed lift angle, the scalloped end surface helix face of identical rotation direction.
As a further improvement on the present invention, the helix angle of end face helicoid is not more than the equivalent friction angle of material.
As further improvement of the present invention, seat watt has at least one fan groove and a circular through hole.
As further improvement of the present invention, there is at least one end face helicoid in seat watt sector structure.
As further improvement of the present invention, screw rod has at least one sector structure that can coordinate with seat watt fan groove.
As further improvement of the present invention, there are at least one end face helicoid and the end face helicoid in sector structure
It is consistent with seat watt end face helicoid rotation direction, spiral lifting.
As further improvement of the present invention, there are four directions or hexagonal structure in described screw rod one end.
As further improvement of the present invention, there is one section of screw thread in the four directions or hexagonal structure lower part, thread rotary orientation with
End face helicoid it is oppositely oriented.
In conclusion the beneficial effects of the invention are as follows：Worker need to not only surpass screw rod along the insertion rotation of seat watt fan groove
Steel pipe can be fastened by crossing half-turn, and it is faster to tighten operation compared to bolt；Conversely, fastener is dismantled rapidly.

Embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
As shown in the figure, This embodiment describes one kind as shown in Figure 1 and Figure 2, a kind of quick locking, dismounting fastener, including lid
Watt (5), seat watt (6), pin (2), axis pin (3), clamp spring (4), screw rod (7), nut (8).Cover tile (5), seat watt (6) use 345B
Steel plate manufactures, cover tile (5), seat watt (6) intrados application diameter 48.3mm steel pipes；Screw rod (7), axis pin (3), pin (2) use
45# steel makings.The end face helicoid that seat watt (6) and screw rod (7) have a pair of identical rotation direction and helix angle is 5 degree；Seat watt (6)
Fan groove and screw rod (7) sector structure cooperate.Cover tile 5), 6) one end is hinged with axis pin (3) for seat watt, axis pin (3) uses clamp spring
(4) retaining；The other end is coupled with the screw rod (7) for putting on nut (8) with (6), and de- using screw thread fastening glue stop nut (8)
Fall；Riveted between fastener member unit (1) with pin (2) hot pressing.Operator need to only insert screw rod (7) along seat watt (6) fan groove
Enter to be rotated by 90 ° and can fasten steel pipe；Conversely, dismounting fastener.
Describe a kind of quick locking, dismounting fastener according to the present invention in an illustrative manner above with reference to attached drawing.But
It will be appreciated by those skilled in the art that a kind of quick locking proposed for the invention described above, dismounting fastener, can also be not
Various improvement are made on the basis of disengaging present invention, or equivalent substitution is carried out to which part technical characteristic, it is all at this
