Abstract
The utility model discloses a kind of casing-pipe connection structure, including multiple sleeve pipes axially connected, and the top of described sleeve pipe is set in connecting pin bores, and connecting pin is fixed on the connecting pin bores；The bottom of described sleeve pipe sets hollow hook, and the connecting pin set by subordinate's sleeve pipe top is embedded in the hollow hook；The outside suit fixes sleeve of described sleeve pipe, the lower end of the fixes sleeve set hollow hook neck, and the connecting pin set by subordinate's sleeve pipe top is stuck in the hollow hook neck；Pin-and-hole is set in the fixes sleeve, axial groove is set in the middle part of sleeve, alignment pin is inserted in fixes sleeve in the pin-and-hole set and in the embedded axial groove.The utility model has the advantages that：It is simple in construction, convenient disassembly, manpower and safe and reliable is saved, the moment of torsion of transmission is larger.
Description
Technical field
Building field is the utility model is related to, specifically a kind of casing-pipe connection structure.
Background technology
In building construction process, longer sleeve structure is generally required, is needed such as in underground hammer drill to as deep as tens
The underground of rice is constructed, and at this moment needs for power to be delivered to the drill bit of underground, sleeve pipe is exactly a kind of conventional selection.It is existing
It is not only complicated using special connector when sleeve structure connects, and effect is bad.Such as Chinese Patent Application No.
201410299953.2 a kind of pipe jointer is disclosed, including the first fixture and the second fixture；Set on the first described fixture
It is equipped with least two screw rods；At least two sliding seat are provided with second fixture；Described two sliding seat are socketed in described respectively
On two screw rods；Be provided with monkey wrench in the sliding seat, the monkey wrench by with the screw rod meshed gears with
The screw rod connection；Be provided with the monkey wrench for control the gear along the screw rod move up and down fall along dial
Fork.Similar patent is also a lot, but is not suitable for transmitting larger moment of torsion.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of pipe connecting structure rational in infrastructure,
Concrete technical scheme is as follows：
A kind of casing-pipe connection structure, including multiple sleeve pipes axially connected, the top of described sleeve pipe set connecting pin bores, even
Pin is fixed in the connecting pin bores；The bottom of described sleeve pipe sets hollow hook, the connecting pin set by subordinate's sleeve pipe top
In the embedded hollow hook；The outside suit fixes sleeve of described sleeve pipe, the lower end of the fixes sleeve set hollow hook neck,
Connecting pin set by subordinate's sleeve pipe top is stuck in the hollow hook neck；Pin-and-hole is set in the fixes sleeve, in sleeve
Portion sets axial groove, and alignment pin is inserted in fixes sleeve in the pin-and-hole set and in the embedded axial groove.
The hollow hook neck is inverted U.
The utility model has the advantages that：It is simple in construction, convenient disassembly, save manpower and safe and reliable, the moment of torsion of transmission
It is larger.

Fig. 1 is attachment structure of the present utility model；
Fig. 2 is connecting pin latch-up structure schematic diagram；
Fig. 3 is the structural representation of sleeve pipe；
Fig. 4 is the structural representation of fixes sleeve；
Fig. 5 is casing part hollow hook structure schematic diagram.
Embodiment
The utility model is illustrated below in conjunction with the accompanying drawings, and as Figure 1-Figure 5, the utility model connects including multiple axial directions
The sleeve pipe 1 connect, the top 13 of described sleeve pipe 1 set connecting pin bores, and connecting pin 3 is fixed in the connecting pin bores；Described sleeve pipe 1
Bottom 11 hollow hook 12 is set, the connecting pin 3 set by subordinate's sleeve pipe top is embedded in the hollow hook 12；Described sleeve pipe 1
Outside suit fixes sleeve 2, the lower end of the fixes sleeve 2 sets hollow hook neck 21, set by subordinate's sleeve pipe top
Connecting pin 3 is stuck in the hollow hook neck 21；Pin-and-hole 22 is set in the fixes sleeve 2, axial groove is set in the middle part of sleeve
5, alignment pin 4 inserts in fixes sleeve in the pin-and-hole set and ensures that fixes sleeve 2 will not phase in the insertion axial groove 5
Sleeve pipe 1 is rotated.
Preferably, the hollow hook neck 21 is inverted U.
