Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a nut, as shown in fig. 1 and 2, including integrated into one piece's nut body 1 and cap 2, nut body 1 is regular hexagon, and cap 2 is located nut body 1's tip, and nut body 1 keeps away from the terminal surface of cap 2 and is equipped with the screw hole 3 that extends to cap 2, and screw hole 3 extends along the length direction of cap 2. Six oil filler points 4 (see figure 3) are circumferentially and evenly distributed on the circumferential side wall of the cap 2, the oil filler points 4 are located in the middle of the cap 2 and are communicated with the threaded holes 3, when the nut rusts, lubricating oil can be injected into the threaded holes 3 through the oil filler points 4, the lubricating oil plays a role in lubrication, and the nut is convenient to disassemble and assemble.

As shown in fig. 2, the end face of the cap 2 away from the nut body 1 is provided with a hexagonal groove 5, when the nut is disassembled, people can rotate the nut body 1 by using a wrench, and can also stretch a hexagonal screwdriver matched with the hexagonal groove 5 into the hexagonal groove 5 to drive the cap 2 to rotate, and the disassembling and assembling modes are diversified.

As shown in fig. 1 and 3, four oil distribution holes 6 communicated with the threaded holes 3 are formed in the inner wall of each oil injection hole 4, and openings, far away from the oil injection holes 4, of the oil distribution holes 6 are distributed at equal intervals along the length direction of the cap 2. Lubricating oil partly spreads to screw hole 3, during another part flows into screw hole 3 through dividing oilhole 6 along oil filler point 4, divides oilhole 6 not only to accelerate the flow rate of lubricating oil, still makes lubricating oil distribution more even, has improved the lubricated effect of lubricating oil to the nut.

As shown in fig. 1 and 3, the inner wall of the oil filling hole 4 is provided with the elastic sheet 7, the elastic sheet 7 is a deformable metal sheet, the upper end of the elastic sheet 7 is fixed at one end of the oil filling hole 4 far away from the threaded hole 3, the elastic sheet 7 can seal the opening of the oil filling hole 4 when being in a natural state, so that impurities such as dust and the like are prevented from entering the oil filling hole 4 and being blocked, and the normal use of the oil filling hole 4 is guaranteed. When the oil filling hole 4 is used, people only need to utilize an oil filling element and the like filled with lubricating oil to push the elastic sheet 7, so that the elastic sheet 7 deforms to one side close to the threaded hole 3, and the operation is convenient.

As shown in fig. 1 and 3, a rubber ring 8 is fixed on the inner wall of the oil filling hole 4, the rubber ring 8 is located at one end of the oil filling hole 4 close to the elastic sheet 7, and when the elastic sheet 7 is in a natural state, the rubber ring 8 abuts against one side of the elastic sheet 7 close to the threaded hole 3. When people press the elastic sheet 7 carelessly, the rubber ring 8 plays a certain limiting role, so that the elastic sheet 7 cannot be easily pushed to open the oil filling hole 4.

As shown in fig. 2 and 3, the end face of the elastic sheet 7 far from the threaded hole 3 is fixed with a moving ring 9, the moving ring 9 comprises a through hole located in the middle of the moving ring 9, if the elastic sheet 7 is clamped in a deformed state under the action of the rubber ring 8, people can pull the moving ring 9 by using a hook matched with the moving ring 9, and then the elastic sheet 7 is driven to reset.

As shown in fig. 1 and 3, a gasket 10 is integrally formed at one end of the nut body 1, which is far away from the cap 2, a nylon sleeve 11 is embedded on the inner wall of the gasket 10, a flared opening 12 is formed at one end of the nylon sleeve 11, which is far away from the threaded hole 3, and the flared opening 12 plays a role in guiding when a bolt matched with the nut extends. An annular fastening ring 13 is integrally formed in the middle of the inner wall of the nylon sleeve 11, and the cross section of the fastening ring 13 is semicircular. When the nut and the bolt are assembled, the nylon sleeve 11 is slightly deformed under the extrusion of the bolt, and the locking effect is achieved.

The implementation principle of the embodiment is as follows: when the nut rusted and clamped dead, people can inject lubricating oil into the oil filling hole 4, one part of the lubricating oil flows into the threaded hole 3 along the inner wall of the oil filling hole 4, the other part of the lubricating oil flows into the threaded hole 3 along the oil distributing hole 6, and the lubricating oil plays a role in lubrication and is favorable for dismounting the nut. When oil is injected, the elastic sheet 7 is pushed by the oil injection element filled with lubricating oil, so that the elastic sheet 7 deforms and extrudes the rubber ring 8, and the opening of the oil injection hole 4 is opened, thereby facilitating oil injection; when the oil filling hole 4 is not used, the elastic sheet 7 is reset, the opening of the oil filling hole 4 can be sealed by the elastic sheet 7 at the moment, and dust and other impurities are prevented from entering the oil filling hole 4 to block the oil filling hole.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
