[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pipe for doors and windows of a machinery cab comprises a main pipe, an inner groove is formed in the middle of the main pipe, a core rod is installed on the inner side of the inner groove, main holes are formed in the upper and lower end walls of the main pipe, side pipes are installed on the upper and lower ends of the main pipe, a through opening is formed in the middle axial direction of the side pipe, a secondary hole is formed in the middle radially of the side pipe, limiting rods are installed on the inner sides of the main hole and the secondary hole, a fixed hole is formed in the end wall of the core rod, and a screw wall is provided on the bottom end wall of the core rod.

[0007] Preferably, the main pipe is threadedly connected to the core rod through an inner groove and a screw wall.

[0008] Preferably, the core rod and the screw wall are fixedly connected, and the main holes are symmetrically distributed about the center of the main pipe.

[0009] Preferably, the side tube is threadedly connected to the core rod through the through opening

[0010] Preferably, the main hole is communicated with the inner groove.

[0011] Preferably, the through opening and the secondary hole are connected, and the limiting rod is threadedly connected to the main hole, the secondary hole and the fixed hole.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. The mandrel and the inner groove are connected together through the screw wall. When the mandrel is rotated, the relative position of the mandrel and the main pipe is changed, which is convenient for moving and adjusting the mandrel. The mandrel is more flexible and convenient to use. The mandrel is threadedly connected to the side pipe through the through port. After the mandrel is rotated and displaced, the side pipe moves accordingly, which is used to change the position of the side pipe, so that the side pipe and the main pipe form a longer support area, which is more flexible when used and is used to adapt to different sizes of mechanical cab doors and windows;

[0014] 2. The limiting rod is screwed into the main hole, the secondary hole and then penetrated into the fixed hole to firmly connect the main pipe, the core rod and the side pipe together, so that the core rod and the side pipe can be locked and limited after the position is adjusted. The relative position between the core rod and the side pipe can also be adjusted, which is more flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
