On offer fourth hole, the side for hook portion of being dashed forward on third through-hole and fourth hole towards top plate in the side wall of transverse tube and riser
Wall copline, and the plane is inclined plane, projection of the side wall on bottom plate on third through-hole close to vertical tube are located at fourth hole
It is interior；
The wedge-shaped bolt is inserted into first, second, third, fourth through hole, and the leading flank of wedge-shaped bolt includes
Upper and lower two vertical planes and the inclined plane for connecting vertical plane, the front side of lower section vertical plane vertical plane above, after wedge-shaped bolt
Side is the inclined plane that can be engaged with the inclined plane of riser,
The cage plate is provided with a centre bore, and centre bore is set on vertical tube, and centre bore periphery is provided with multiple for making extension
The sets of holes that the prominent hook portion of hook is caught on；
The helical spring is in housing, both ends difference coupling hook riser and transverse tube.
In the present embodiment, the front-rear side walls on the housing close to vertical tube one end are provided with and can accommodate cage plate and stretch into housing
Neck.
In the present embodiment, the lower end of the wedge-shaped bolt trailing flank is provided with the prominent hook forward extended out, and works as wedge-shaped bolt
Leading flank and trailing flank respectively side fitting corresponding with first through hole and the second through hole when, the inclined plane of wedge-shaped bolt leading flank
Can be with cage plate lower surface EDGE CONTACT.
In the present embodiment, the lateral wall of the housing and hook is the face of cylinder, is contacted on housing with scaffold vertical tube
End face has the face of cylinder that can be bonded with vertical tube side wall.
In the present embodiment, the prominent hook portion of the hook has two, has been distributed uniformly and circumferentially on the cage plate more
Group sets of holes group, every group of sets of holes group have two can correspond to the sets of holes for catching on the prominent hook portion of hook, and the set hole length is more than prominent hook portion
Length, be provided with oblique pull bar jack between two adjacent groups sets of holes group.
In the present embodiment, the first through hole, the second through hole, third through-hole and fourth hole are square hole.
In the present embodiment, the end being connected on the housing with transverse tube is connected with a short tube, the helical spring one
End is connected with short tube end, and the short tube outer wall is provided with a journal stirrup, and a flower basket bolt, the short tube end are connected with the journal stirrup
Portion is connected with a regulating bolt, the flower basket bolt and regulating bolt to wall connecting.
In the present embodiment, the end being connected on the scaffold transverse tube or short tube with helical spring is provided with baffle plate, institute
Helical spring is stated to be fixed on baffle plate.
The operation principle of said mechanism is as follows：
After the completion of Standard as depicted, it is only necessary to suppress wedge-shaped bolt downwards, utilize wedge-shaped bolt and hook
The mutual slip of riser inclined plane makes hook compression helical spring be moved to transverse tube side, so that hook tenses with cage plate, this
When, the face of cylinder of housing end face is bonded with vertical tube side wall, so that latch gear locks transverse tube and vertical tube.In locking state
Under, inclined plane and the cage plate lower end denomination EDGE CONTACT of wedge-shaped bolt leading flank.
When needing to dismantle latch gear, it is only necessary to tap the lower end of wedge-shaped bolt, wedge-shaped bolt is transported upwards
It is dynamic, using mutual slip of the wedge-shaped bolt with hook riser inclined plane and helical spring the elastic force for linking up with riser is made hook to
Vertical tube side is moved, so that the sets of holes of hook and cage plate loosen, during wedge-shaped bolt is moved upwards, wedge shape is inserted
Sell the inclined plane of leading flank and relative slip occurs with the edge of cage plate lower surface, so as to promote wedge-shaped bolt to drive housing gradually remote
From vertical tube, to reach the purpose of fast quick-detach latch gear.
For the principle of above-mentioned fast quick-detach latch gear, do as described below.
If latch gear removed from cage plate it can be seen from the structure provided by the present embodiment, it is necessary first to will
The prominent hook portion of hook is taken out from the sets of holes of cage plate, then makes latch gear overall and retreats a segment distance along cross tube direction is horizontal,
Latch gear is moved horizontally a segment distance to the left side of transverse tube or right side, just latch gear can made really to divide with cage plate
From.Because in the present embodiment, the housing of latch gear and the connecting end surface of vertical tube have a face of cylinder, to ensure housing end face
Contacted with vertical tube in face, the structure can make the stability of latch gear higher.Based on the structure of this face contact, due to transverse tube
The other end is integrally fixed on another latch gear, therefore is difficult to transverse tube side by manpower by the housing of the latch gear
Pull, then due to housing end face and vertical tube use Cylindrical Surfaces Contact, when housing is only longitudinally moved along vertical tube outer wall
When dynamic, latch gear can not be taken off from cage plate, now, the inclined plane of wedge-shaped bolt leading flank can play very well
Effect, i.e. the inclined plane when wedge-shaped bolt is moved upwards, can to cage plate produce thrust, so as to promote wedge-shaped bolt to drive
Housing retreats a segment distance along cross tube direction is horizontal, then can now make latch gear to the left side of transverse tube by manpower or
Right side moves horizontally a segment distance, you can really separates latch gear cage plate.
In the present embodiment, it is necessary to illustrate, when each side of first through hole and third through-hole is alignd, the second through hole
Also just alignd with fourth hole.
In the present embodiment, also an innovative point is, a short tube is provided with latch gear, is connected on short tube
Flower basket bolt and regulating bolt, its main function are in order that the vertical tube close to wall side understands with wall, are ensured whole
The stability of scaffold.Flower basket bolt and regulating bolt and short tube composition triangular structure, its stability are more preferable.
