Abstract
The utility model discloses a steel pipe connection joint, which comprises a connecting pipe, wherein an inner cavity of the connecting pipe is sheathed with a flexible sealing sleeve; two end ports of the sealing sleeve are respectively provided with an annular flanging which extends outward in the radial direction; the inner side of the annular flanging is provided with an annular groove; the width of the annular groove is greater than or equal to the thickness of a pipe wall of the connecting pipe. When two steel pipes are connected together, the two connected steel pipes are inserted into a connection joint, which causes the two connected steel pipes to be butted together on the middle part of the sealing sleeve. Because the inner and the outer circumferences of the sealing sleeve are provided with anti-back pawls, the inserted steel pipes are not easy to retreat out from the connection joint, which ensures the quality of connection of the steel pipes. The utility model has the advantages of simple structure and convenient and fast use process, and is applicable for steel pipes with thin and thick walls. The utility model do not need to match special equipment or specialized technical personnel, and is free from the limit of operation environment, which reduces construction cost and enhances work efficiency of connecting steel pipes.
Description
Technical field
The utility model relates to a kind of pipeline connector element, just relates to a kind of steel pipe jointing specifically.
Background technique
In building site construction, for the stake bed rock layer sampling to building detects or pile foundation quality detected, after needing will many steel pipes be connected with each other colligation to reinforcement cage, with the reinforcement cage sinking in the stake hole.Welding or thread connecting mode are adopted in the connection of steel pipe at present more, and these two kinds of Placements all require connected steel pipe tube wall that certain thickness is arranged, otherwise steel pipe can maybe can't be cut with scissors tooth by burn-through.And these two kinds of method attended operation difficulty are big, welding machine or the hinge tooth machine special as needs, and must carry out execute-in-place by experienced skilled worker, so not only increased construction cost, inefficiency has also influenced construction speed, has improved engineering cost on the whole.
Summary of the invention
The purpose of the utility model is to provide a kind of steel pipe jointing simple in structure, easy for installation.
For achieving the above object, the utility model can be achieved through the following technical solutions:
Steel pipe jointing described in the utility model comprises connecting tube, is set with flexible gland in described connecting tube inner chamber; Two-port at described stuffing box gland is respectively arranged with the ring-type flange that extends radially outward; Inner side surface at described ring-type flange offers annular groove; The width of described annular groove is more than or equal to the connecting tube pipe thickness.
The inner and outer circumferential surfaces of described stuffing box gland is provided with the anti-back pawl.
Advantage of the present utility model is to have adopted technique scheme, and when two steel pipes were linked together, the steel pipe that two velamens connect inserted from the two-port of described jointing, and making is docking together in described stuffing box gland intermediate portion by two steel pipes that connect gets final product.Because the inner and outer circumferential surfaces of stuffing box gland is provided with the anti-back pawl, steel pipe inserts the back and is difficult for withdrawing from from jointing, has guaranteed the quality of connection of steel pipe.For improving connection stability, can on the steel pipe that needs connect, locating piece be set in advance in actual the use, so just can reach better connection effect.The utility model is simple in structure, and using process is convenient and swift, and steel pipe thin, heavy wall all is suitable for, and need not join special device and professional and technical personnel, and not be subjected to the restriction of operating environment, has reduced construction cost widely, has improved the connection working efficiency of steel pipe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, steel pipe jointing described in the utility model comprises connecting tube 1, is set with flexible gland 2 in described connecting tube 1 inner chamber; Two-port at described stuffing box gland 2 is respectively arranged with the ring-type flange 3 that extends radially outward; Inner side surface at described ring-type flange 3 offers annular groove 4; The width of described annular groove 4 equals connecting tube 1 pipe thickness.More firm for steel pipe is connected, the inner and outer circumferential surfaces of described stuffing box gland 2 is provided with anti-back pawl 5,6.
Claims (2)
