Detailed Description

As shown in fig. 1-3, a combined locknut comprises a bolt 1 and a hexagon nut 2 matched with the bolt 1, wherein two side surfaces 3 of the hexagon nut 2, which are parallel to each other, are respectively provided with a locking structure, each locking structure comprises a through hole 4, each through hole 4 is formed on the two side surfaces 3 of the hexagon nut 2, which are parallel to each other, an insertion rod 5 is penetrated in each through hole 4, one end, far away from each through hole 4, of each insertion rod 5 is fixedly connected with an operation plate 6, the inner side of each operation plate 6 is fixedly connected with a compression spring 7, the compression springs 7 are positioned on two sides of each insertion rod 5, two grooves 8 are symmetrically formed on the bolt 1, each groove 8 corresponds to the position of each insertion rod 5, and each insertion rod 5 corresponds to the position of each groove 8; specifically, the hexagonal nut 2 is in threaded connection with the bolt 1, so that the two insertion rods 5 respectively enter the corresponding grooves 8, and the hexagonal nut can be prevented from loosening; when the hexagonal nut 2 needs to be unscrewed, the insert rod 5 is pulled outwards, and the compression spring 7 deforms, so that the insert rod 5 is out of the groove 8, and the hexagonal nut 2 is unscrewed.

The hexagonal nut 2 is radially symmetrically provided with an insertion hole 9, a limiting plate 10 is inserted into the insertion hole 9, and one end surface of the limiting plate 10 is contacted with the end surface of the operation plate 6; specifically, the compression spring 7 is in a natural state, the insertion rod 5 passes through the through hole 4 and is perpendicular to the threaded hole 10, when the insertion rod 5 is screwed onto the bolt 1, the insertion rod 5 which is pulled at both ends all the time is not contacted with the bolt 1, so that the operation is inconvenient, the end part of the insertion rod 5 is limited by the limiting plate 10, and the insertion rod is not led into the threaded hole 10, so that the hexagonal nut 2 is conveniently screwed onto the bolt 1.

The insertion hole 9 is communicated with the through hole 4; specifically, the stopper plate 10 is inserted into the insertion hole 9 to thereby limit the insertion rod 5.

One end of the compression spring 7 is fixedly connected with the operation plate 6, and the other end of the compression spring 7 is fixedly connected with the end face of the hexagonal nut 2; specifically, the insert rod 5 is fixed to the hexagonal nut 2 by the compression spring 7, and when the insert rod 5 is required to be screwed off, the compression spring 7 is deformed by pulling the insert rod 5 outward.

When the compression spring 7 is in a natural state, the insertion rod 5 is inserted into the corresponding groove 8; specifically, the insertion rod 5 is pulled in a direction away from the threaded hole 10, so that the compression spring 7 is deformed, the insertion rod 5 is not positioned in the groove 8, and the hexagonal nut 2 can be removed; when the inserting rod 5 is loosened, the compression spring 7 is restored, and the inserting rod 5 is penetrated into the groove 8, so that the hexagonal nut 2 is not easy to loosen.

An operation ring 12 with a semicircular longitudinal section is fixedly connected to the outer end surface of the operation plate 6; when the operation plate 6 is pulled outwards, the operation ring 12 can be pulled, so that the operation is convenient.
