FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;

fig. 3 is a schematic view of the B-B orientation of fig. 1.

In the figure: the pipe comprises a pipe body 1, a connecting disc 2, a threaded hole 3, a locking bolt 4, a clamping groove 5, a driving groove 6, a driving plate 7, a spring 8, a locking strip 9 and a pressing plate 10.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-3, a flame retardant MPP cable sheath tube convenient to connect comprises a tube body 1 and a connecting component, wherein the connecting component comprises a connecting disc 2, a driving plate 7, a pressing plate 10 and a locking strip 9, the side wall of the tube body 1 is provided with a driving groove 6, the driving plate 7 is slidably arranged in the driving groove 6, the pressing plate 10 is fixedly connected to the upper end of the driving plate 7, the locking strip 9 is also fixedly connected to the upper end of the driving plate 7, the driving plate 7 is connected to the driving groove 6 through a spring 8, the connecting disc 2 is sleeved outside the tube body 1, the side wall of the connecting disc 2 is provided with a clamping groove 5, and the locking strip 9 extends into the clamping groove 5.
