Detailed description of the invention
With specific embodiment, the present invention is described in further details below in conjunction with the accompanying drawings:
The penetration pipe elbow with roller bearing 2 as depicted in figs. 1 and 2, including elbow tube wall 1 be arranged at described swan neck
At least one roller bearing 2 in wall 1, the inlet and outlet of described elbow tube wall 1 has angle, and all described roller bearings 2 are respectively provided with
In the angle of described elbow tube wall 1, described roller bearing 2 can rotate along the import of described elbow tube wall 1 to Way out.
Electric wire is after the import through described elbow tube wall 1, and the camber along described elbow tube wall 1 is curved and highlights institute
State the outside tube wall outlet, during pulling electric wire, electric wire near described roller bearing 2, and can under the rolling of roller bearing 2
Slide in described elbow tube wall 1, i.e. reduce the electric wire frictional force in the angle of elbow tube wall 1 by described roller bearing 2, convenient
Electric wire slides.
The cross section of described elbow tube wall 1 is double-deck meander line structure, and the cross section of described elbow tube wall 1 includes short broken line
11 and long broken line 12, and the axis of described roller bearing 2 to the distance of described short broken line 11 less than the distance to described long broken line 12, i.e.
Described roller bearing 2 is positioned close to described elbow tube wall 1 moving pivot direction so that electric wire can be fitted institute during pulling
State roller bearing 2.
It is provided with rounding at the knuckle of described short broken line 11 and at the knuckle of described long broken line 12, makes elbow tube wall 1
Arc transition, reduces electric wire frictional force in described elbow tube wall 1.
