Installation nut
An installation nut includes a body, an upper cover, at least two threaded blocks, and a transmission member. The upper cover is fixedly connected to the body. An inner wall of each of the at least two threaded blocks includes an internal thread, and an outer wall of each of the at least two threaded blocks includes a first inclined surface and a first straight surface. The transmission member is movably disposed between the body and the upper cover. A top surface of the transmission member includes one or more transmission blocks configured to extend out of the upper cover. A lower end of the transmission member includes at least one second straight surface configured to couple with the first straight surfaces and at least one second inclined surface configured to couple with the first inclined surfaces.
1. An installation nut configured to thread with a threaded rod, comprising:
a body comprising a first through hole,
an upper cover,
at least two threaded blocks, and
a transmission member, wherein:
the upper cover is fixedly connected to the body and comprises a second through hole corresponding to the first through hole,
an inner wall of each of the at least two threaded blocks comprises an internal thread,
an outer wall of each of the at least two threaded blocks comprises a first inclined surface and a first straight surface,
the transmission member is movably disposed between the body and the upper cover and is configured to move in a vertical direction,
a top surface of the transmission member comprises one or more transmission blocks configured to extend out of the upper cover,
a lower end of the transmission member comprises at least one second straight surface configured to couple with the first straight surfaces of the at least two threaded blocks and at least one second inclined surface configured to couple with the first inclined surfaces of the at least two threaded blocks,
when the installation nut surrounds an outer side of the threaded rod and upwardly abuts a countertop:
the one or more transmission blocks move downward and drive the at least two threaded blocks to move toward a central axis of the at least two threaded blocks until the at least two threaded blocks are locked with the threaded rod by cooperation of the first inclined surfaces of the at least two threaded blocks and the at least one second inclined surface, and
when the at least two threaded blocks are locked with the threaded rod:
the first straight surfaces of the at least two threaded blocks abut an inner side of the at least one second straight surface to limit the at least two threaded blocks from moving in a radial direction of the at least two threaded blocks.
2. The installation nut according to claim 1 , wherein the transmission member defines an annular closed structure.
3. The installation nut according to claim 2 , wherein a cross-section of the at least one second inclined surface defines a closed ring.
4. The installation nut according to claim 1 , comprising:
a C-ring, wherein:
the inner wall of each of the at least two threaded blocks comprises a C-ring groove, and
the C-ring is disposed in the C-ring grooves.
5. The installation nut according to claim 1 , comprising:
an elastic reset member, wherein:
two ends of the elastic reset member respectively abut the transmission member and the body.
6. The installation nut according to claim 1 , wherein at least one of the first inclined surfaces of the at least two threaded blocks or the first straight surfaces of the at least two threaded blocks comprises one or more grooves.
7. The installation nut according to claim 1 , wherein:
the upper cover comprises one or more through holes, and
the one or more transmission blocks extend into the one or more through holes and are configured to move in the vertical direction along the one or more through holes.
8. The installation nut according to claim 1 , wherein:
the upper cover comprises one or more locking buttons extending downward,
an inner wall of the first through hole comprises one or more locking grooves, and
the upper cover is fixedly connected to the body through a clamping cooperation of the one or more locking buttons and the one or more locking grooves.
9. The installation nut according to claim 1 , wherein a mounting seat is disposed between the installation nut and the countertop.
