Abstract
A kind of elbow, comprise the first joint and the second joint, described first joint comprises elbow body and is placed on the first connecting tube on elbow body one end; Described elbow body and the first connecting tube all have the annular groove of corresponding placement steel ball; When steel ball is put in annular groove, described steel ball is between elbow body and the first connecting tube; The second connecting tube that described second joint comprises body and is integrated with body; Described second connecting tube is threaded with the first connecting tube.The utility model to be threaded the second connecting tube by the first connecting tube, and the first connecting tube and elbow body are for be socketed, the setting of steel ball defines the first connecting tube tube body of can only going for a stroll and rotates, ensure that the second joint can be connected on the first joint, and solve when one end is tightened and easily occur that the malposition of the other end causes the problem that cannot connect.
Description
Technical field
The utility model relates to a kind of elbow.
Background technique
Bend pipe adopts complete bending mould to bend, and is divided into cold stewing and picks two kinds of techniques.No matter be any machinery equipment and pipeline, major part all uses bend pipe, mainly in order to oil transportation, gas transmission, transfusion etc.Bend pipe is in the process connected, and the bend pipe be particularly threaded, easily occurs when at one end tightening that the malposition of the other end causes connecting.
Model utility content
The utility model is exactly easily occur that the malposition of the other end causes the technical problem that cannot connect to solve when the bend pipe that is threaded at one end is tightened.
For solving the problems of the technologies described above, the technical solution of a kind of bend pipe of the utility model is:
Comprise the first joint and the second joint, described first joint comprises elbow body and is placed on the first connecting tube on elbow body one end; Described elbow body and the first connecting tube all have the annular groove of corresponding placement steel ball; When steel ball is put in annular groove, described steel ball is between elbow body and the first connecting tube; The second connecting tube that described second joint comprises body and is integrated with body; Described second connecting tube is threaded with the first connecting tube.
When described second connecting tube is threadedly connected on the first connecting tube, the second connecting tube, between the first connecting tube and elbow body, is fitted by a seal ring between described body and elbow body.
The technique effect that the utility model can reach is: the utility model to be threaded the second connecting tube by the first connecting tube, and the first connecting tube and elbow body are for be socketed, the setting of steel ball defines the first connecting tube tube body of can only going for a stroll and rotates, ensure that the second joint can be connected on the first joint, and solve when one end is tightened and easily occur that the malposition of the other end causes the problem that cannot connect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the partial sectional view of a kind of elbow of the utility model.
Embodiment
Below in conjunction with accompanying drawing, elaboration detailed is further done to the utility model.
Consult Fig. 1.
Mode of execution one one kinds of elbows, comprise the first joint 1 and the second joint 2, and described first joint 1 comprises elbow body 11 and is placed on the first connecting tube 12 on elbow body 11 one end; Described elbow body 11 all has the annular groove of corresponding placement steel ball 4 with the first connecting tube 12; When steel ball 4 is put in annular groove, described steel ball 4 is between elbow body 11 and the first connecting tube 12; The second connecting tube 21 that described second joint 2 comprises body 22 and is integrated with body 22; Described second connecting tube 21 is threaded with the first connecting tube 12.The utility model to be threaded the second connecting tube 21 by the first connecting tube 12, and the first connecting tube 12 and elbow body 11 are for be socketed, the defining the first connecting tube 12 tube body 11 of can only going for a stroll by the annular groove of the first connecting tube 12 and the annular groove of elbow body 11 and rotate of steel ball 4, ensure that the second joint can be connected on the first joint, and solve when one end is tightened and easily occur that the malposition of the other end causes the problem that cannot connect.
Mode of execution two, based on mode of execution one, when described second connecting tube 21 is threadedly connected on the first connecting tube 12, the second connecting tube 21, between the first connecting tube 12 and elbow body 11, is fitted by a seal ring 3 between described body 22 and elbow body 11.Though the utility model is under desirable state, when the second connecting tube 21 is connected on the first connecting tube 12, the elbow body 11 as long as the second connecting tube 21 has been fitted to solve leakage water problem, but reality is difficult to accomplish, the design of seal ring 3 solves this problem.
