用于允许天线桅杆相对于其支柱枢转运动的装置

Apparatus for allowing pivotal movement of an antenna mast relative to its support post
Abstract:
An apparatus (10) for attaching an antenna mast (11) to a post (12) positioned in the ground includes a bracket (14) attached to the mast (11). A plate (13) is attached to the post (12). The plate has a slot (32) which receives a bolt (30) that extends through the mast (11) and the bracket (14). The plate also has an elongate opening (33) which receives a bolt (31) that extends through the mast (11) and the bracket (14). Nut assemblies (34) are provided for the bolts (30, 31) and when tightened, the mast (11) and the bracket (14) are attached to the plate (13) and the post (12). But when loosened, the bolt (30) may be moved in slot (32) and bolt (31) may be moved in opening (33) until the bolt (30) is out of the slot (32) at which time the mast (11) and the bracket (14) may be rotated relative to the post (12) and the plate (13).
Abstract(Chinese):

用于将天线杆（11）附接到位于地面中的柱（12）的装置（10）包括附接到桅杆（11）的支架（14）。 板（13）附接到柱（12）。 板具有槽（32），其容纳延伸穿过桅杆（11）和支架（14）的螺栓（30）。 该板还具有一个细长的开口（33），该开口（33）容纳延伸穿过桅杆（11）和支架（14）的螺栓（31）。 为螺栓（30,31）提供螺母组件（34），并且当紧固时，桅杆（11）和支架（14）附接到板（13）和柱（12）。 但是当松开时，螺栓（30）可以在槽32中移动，并且螺栓（31）可以在开口（33）中移动，直到螺栓（30）离开槽（32），此时桅杆 11）并且支架（14）可以相对于柱（12）和板（13）旋转。
