The locating ring connect.Locating ring is supported between positioning screw rod and embedded sleeve barrel, in order to avoid on the outside of embedded sleeve barrel during casting concrete,
By embedded sleeve barrel crimp.
And in actual mechanical process, the possible thickness of pipeline through floor is different, i.e. the pipe of required embedded sleeve barrel
Footpath is also different.If using above-mentioned pre-buried fixator, it is necessary to customized pre- with different tube diameters during the embedded sleeve barrel of pre-buried different tube diameters
Bury the locating ring of sleeve matching, it has not been convenient to operate.
Utility model content
The purpose of this utility model is to provide a kind of threading service sleeve locator, its internal telescopic positioning of setting
Part, same keeper can be realized to be positioned with the matching of the embedded sleeve barrel of different tube diameters.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of threading service sleeve
Locator, including the positioning screw rod being vertically plugged on slab form, and the embedded sleeve barrel on the outside of positioning screw rod is set in, it is fixed
Position screw mandrel periphery connection regulating part and keeper, set detent mechanism between regulating part and keeper, detent mechanism is included along fixed
The position circumferentially spaced some support bar groups of screw mandrel, support bar group with regulating part including being driven, one end is slided along positioning screw rod
Upper support bar, and the lower support bar that one end and upper support bar are be hinged, the other end abuts with keeper, upper support bar and lower branch
The pin joint of strut abuts with embedded sleeve barrel madial wall.
Using above technical scheme, the position progress that positioning screw rod is plugged on slab form to embedded sleeve barrel is tentatively fixed
Position, the outside of abutment sleeve select the embedded sleeve barrel of different tube diameters according to actual conditions.The casting concrete on the outside of abutment sleeve
When, concrete exerts a force to abutment sleeve, and abutment sleeve may shift.The society debugging machine between positioning screw rod and embedded sleeve barrel
Structure, to close to keeper direction move regulating part when, upper support bar and lower support bar move closer to, the be hinged site of the two by
Gradually close to the madial wall of embedded sleeve barrel.When the be hinged site of upper support bar and lower support bar abuts with the madial wall of embedded sleeve barrel
When, the position of regulating part determines therewith, and now, embedded sleeve barrel is under the restriction of upper support bar and lower support bar, itself and positioning filament
The position of bar is relatively fixed, it is not easy to is shifted.
In addition, regulating part upwardly or downwardly slides along positioning screw rod, the hinge of upper support bar and lower support bar can be adjusted
The vertical range in site and positioning screw rod axis is connect, and then the embedded sleeve barrel of different tube diameters can be positioned.
Further, detent mechanism also includes upper connection ring that is be hinged with upper support bar, being abutted with regulating part, and with
The lower connection ring that support bar is be hinged, is abutted with keeper.
Using above technical scheme, one end of upper support bar and lower support bar is be hinged to form be hinged site, upper support bar
The other end is hinged with upper connection ring, and upper connection ring abuts with regulating part.Because upper support bar and lower support bar are around positioning screw rod
It is circumferentially arranged multigroup, the upper connection ring slip of regulating part promotion, you can realize and drive multiple upper support bars motions simultaneously.Lower support bar
It is hinged with lower connection ring, lower connection ring abuts with keeper, facilitates more lower support bars while positions.
Further, positioning screw rod periphery is arranged compression elastic piece, and compression elastic piece is connected to connection ring and lower connection
Between ring.
Using above technical scheme, compression elastic piece and regulating part clamp connection ring, compression elastic piece and keeper
