Abstract
The utility model discloses an improved pipe connecting piece. The pipe connecting piece comprises a left pipe body, a right pipe body and a connecting device, wherein the right pipe body is of a hollow pipe, the left pipe body is inserted in the right pipe body, the pipe connecting piece is characterized in that the connecting device consists of a connecting sleeve and a fastener, one end of the fastener is arranged in the right pipe body, the other end of the fastener is sheathed outside the left pipe body, the connecting sleeve has an internal thread, the right pipe body is provided with an outer thread matched with the inner thread of the connecting sleeve which is internally provided with a slope, and the connecting sleeve, the fastener and the left pipe body are in tight fit. According to the utility model, the left pipe body is inserted in the right pipe body, the left and right pipe bodies are connected through the connecting sleeve and the fastener, and the connecting sleeve is relatively short, so that the machining is convenient, the production cost is relatively low and the pipe connecting piece can also be applicable to connection of long pipes.
Description
Technical field
The utility model relates to a kind of improvement invention of tubular union, particularly be the link between a kind of pipeline.
Background technique
It generally is that two pipes adopt screw thread directly to connect that existing pipeline connects; Promptly a pipe is provided with outside thread; Another pipe is provided with internal thread, because the very inconvenience of the internal thread machining of pipe, pipe is grown more difficult processing more; Therefore adopt this kind mode to connect and have narrow limitation, can only be used to connect short pipe.
Summary of the invention
In view of the existing technical problem of background technique, the utility model technical problem to be solved provides a kind of tubular union that is applicable to the pipe that connects virtually any size.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme to realize: this kind tubular union includes left body, right body and connection set; Said right body is a hollow tube, and said left body inserts in the right body, it is characterized in that said connection set includes connecting sleeve and fastener; One end of said fastener places in the right body; The other end of said fastener is placed in outside the left body, and said connecting sleeve has internal thread, and said right body is provided with the outside thread that the internal thread with connecting sleeve is complementary; Be provided with the inclined-plane in the said connecting sleeve, said connecting sleeve, fastener and left body three close-fitting.
The utility model inserts left body in the right body, and an end of fastener places outside the left body, owing to be provided with the inclined-plane in the connecting sleeve; Therefore when connecting sleeve was threaded with right body, connecting sleeve was inwardly pressed fastener hard, and fastener is locked left body; Connecting sleeve, fastener and left body three close-fitting; Be in locking state, connecting sleeve then is threaded with right body again, thereby has realized that left body is connected with right body.Because connecting sleeve is comparatively short and small, thereby easy to process, cost of production is lower, and is also suitable for the connection of long tube.
Description of drawings
Further describe the structure and the relevant details thereof of the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic representation after the connection of the utility model.
Schematic representation when Fig. 3 separates for the left and right body of the utility model.
Embodiment
With reference to accompanying drawing, this kind tubular union includes left body 1, right body 6 and connection set; Said right pipe 6 bodies are hollow tube, and said left body 1 inserts in the right body 6, and said connection set includes connecting sleeve 2 and fastener 4; One end of said fastener 4 places in the right body 6; The other end of said fastener 4 is placed in outside the left body 1, and said connecting sleeve 2 has internal thread 3, and said right body 6 is provided with the outside thread 5 that the internal thread with connecting sleeve is complementary; Be provided with inclined-plane 7 in the said connecting sleeve 2, said connecting sleeve 2, fastener 4 and left body 1 three's close-fitting.
When the utility model is installed, left body 1 is inserted in the right body 6, an end of fastener 4 is in right body 6 at this moment; The other end is placed in outside the left body 1, and said connecting sleeve 2 passes left body 1 and is threaded with right body 6, owing to have inclined-plane 7 in the connecting sleeve 2; Connecting sleeve 2 is close to fastener 4 and left body 1, makes connecting sleeve 2, fastener 4 and left body 1 three's close-fitting, is in locking state; At this moment, left body 1 is connected with right body 6; During dismounting,, it is separated with right body 6, left body 1 is extracted got final product connecting sleeve 2 counterrotatings.
