Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

As shown in fig. 1 and 2, a structure of an anti-seize nut provided for an embodiment includes:

a nut seat 2; the nut seat 2 is provided with a guide groove 9;

the screwing piece 8 is slidably arranged in the guide groove 9; and the screwing part 8 is in threaded fit with the bolt 1;

the elastic piece 7 is arranged between the screwing piece 8 and the inner wall of the guide groove 9 and is used for drawing the screwing piece 8 to move into the guide groove 9;

the fastening piece 3 is inserted in the guide groove 9 in a sliding mode and is used for pressing the screwing piece 8 towards the center of the nut seat 2.

In one aspect of this embodiment, in use, the fastening member 3 is inserted into the guiding groove 9, so that the screwing member 8 moves toward the center of the nut seat 2, the bolt 1 is slowly screwed into the inner hole of the nut seat 2, the bolt 1 is screwed with the screwing members 8, and the inner surface of the screwing member 8 is equivalent to the inner surface of the threaded hole of the conventional nut, and can perform the same fixing function as the conventional nut. When the nut needs to be disassembled, the nut seat 2 can be directly rotated, the nut is rotated, but when the nut is seized, the fastener 3 can be pulled out from the guide groove 9, the screwing piece 8 retracts into the guide groove 9 under the action of the elastic piece 7, so that the gap between the screwing piece 8 and the bolt 1 is increased, the bolt 1 and the nut can be easily detached and disassembled, and the problem that the nut and the bolt are seized and difficult to disassemble due to thread damage or corrosion is effectively solved.

In one embodiment of the present invention, the elastic element 7 may be a spring as shown in fig. 1, and besides, the elastic element 7 may also be replaced by other elastic components, such as a silica gel column, an elastic sheet, etc., which is not limited in this embodiment. The number of the elastic members 7 may be plural, and the plurality of the screwing members 8 may be uniformly arranged along the circumferential direction.

As shown in fig. 1 and 2, in one embodiment, the anti-galling nut further comprises a lubrication assembly.

In one aspect of this embodiment, as shown in connection with FIG. 1, the lubrication assembly includes:

the oil cavity 6 is arranged on the nut seat 2 and is communicated with the guide groove 9;

and the piston 5 is slidably arranged in the oil cavity 6 and is used for extruding the lubricating oil in the oil cavity 6 into the guide groove 9.

In the process of the embodiment, the piston 5 in the lubricating assembly moves in the oil chamber 6, so that the lubricating oil in the oil chamber 6 is squeezed, and the lubricating oil seeps out from the oil hole where the oil chamber 6 is communicated with the guide groove 9, so that the screwing piece 8 in the guide groove 9 and the contact surface of the screwing piece 8 and the bolt 1 are lubricated, the matching resistance is reduced, and the use is convenient.

In one aspect of the present embodiment, as shown in fig. 1 and 3, the fastener 3 includes:

an operation section 30;

a connecting portion 32 connected to the piston 5 in the lubricating assembly;

and the pressing part 31 is inserted in the guide groove 9 and is used for pressing the screwing piece 8. The cross-sectional shape of the pressing portion 31 is trapezoidal. When the push operation part 30 moves, the connection part 32 pushes the piston 5 to move so that the lubricating oil enters the guide groove 9, and the pressing part 31 pushes the screwing member 8 to move at the same time.

In one aspect of the present embodiment, as shown in fig. 1, a fastener 4 for fixing the operation portion 30 to the nut holder 2 is provided between the operation portion 30 and the nut holder 2. When the nut and the bolt 1 are installed in the direction shown in fig. 1, the fastening piece 3 is not easy to fall off from the nut seat 2, but when the nut seat 2 is turned over by 180 degrees, the fastening piece 3 is likely to fall off, so the fastening piece 4 is additionally arranged to fix the fastening piece 3 on the nut seat 2 and prevent the fastening piece 3 from falling off in the using process.
