Abstract

A plumb probe assembly for a level measuring device has a plumb and a connection assembly. The plumb has an inner connecting tube. The connection assembly has two connectors and two clip brackets. The connectors are slidably mounted together while one of the connector firmly connects to the inner connecting tube of the plumb. The clip brackets are movably connected together by at least one resilient device supplying a clipping force and clip around the connectors to hold connectors firmly together. When a force greater than the clipping force, applied to the plumb, the clip brackets separate and the plumb falls into the particulates in the container. The plumb will not cause damage to a particulate discharging device and will disconnect with the connection assembly. A replacement plumb may then be attached to the connection assembly for continued operation.

A plumb probe assembly for a level measuring device comprising

a plumb being hollow, breakable and having
a bottom;
a top;
and
an inner connecting tube being formed on and protruding coaxially from the top of the plumb and having
an outer surface;
and
a through hole being formed coaxially through the inner connecting tube;
and
a connection assembly being mounted on the inner connecting tube of the plumb and comprising
an inner connector having
a neck having two ends;
a mounting head being formed on and protruding from one end of the neck and having an abutting surface;
and
a connecting end being formed on and protruding from the other end of the neck;
an outer connector being mounted slidably around the inner connector and comprising
a sheath being mounted slidably around the neck of the inner connector and having
a sidewall;
and
an end;
two mounting slots being formed transversely and oppositely through the sheath and corresponding to the neck of the inner connector;
and
a connecting end being formed on and protruding from the end of the sheath;
and
a tension clip being mounted around the outer connector and partially in the mounting slots of the outer connector, abutting the neck of the inner connector and the abutting surface of the mounting head of the inner connector and having
two clip brackets are movably connected to each other, corresponding to and being mounted around the outer connector and respectively and partially in the mounting slots, abutting the neck of the inner connector, selectively holding the outer connector firmly to the inner connector and each clip bracket having
a central segment abutting the neck of the inner connector and having
two longitudinal edges;
and
two transverse edges;
and
two mounting tabs being formed respectively on and protruding from the transverse edges of the central segment, wherein each mounting tab corresponds to one of the mounting tabs of the other clip bracket to form two pairs of corresponding mounting tabs;
and
at least one compression assembly being mounted through at least one pair of the corresponding mounting tabs of the clip brackets, providing a clipping force to allow the clip brackets to be moveably connected to each other and selectively openable and each one of the at least one compression assembly having
a fastener being mounted through a corresponding pair of the corresponding mounting tabs of the clip brackets and having two ends;
and
a resilient device being mounted around the fastener and between the one end of the fastener and a corresponding one of the mounting tabs of the clip brackets.
