Disclosure of Invention

In order to overcome the not enough of background art, the utility model provides a screw thread oiling in the ability nut leads to the novel nut of nut quick detachable.

The utility model adopts the technical proposal that: the utility model provides a novel nut, including the nut body, the top of nut body be equipped with the cavity, the cavity top is equipped with the opening, the bottom is equipped with interior opening, be equipped with in the cavity and open or sealed check valve with the opening, be equipped with the guiding mechanism that can lead oil to the screw thread of nut body between the internal surface of nut body and the check valve.

Adopt above-mentioned technical scheme, the cavity has been set up at the nut top, and the check valve has been set up, set up water conservancy diversion mechanism on the inner wall, when dismantling the nut, can aim at the opening earlier towards the cavity oiling, owing to the check valve, consequently can open the opening, the oil is annotated and is entered and flow to screw thread department through water conservancy diversion mechanism, lubricate the screw thread, then when dismantling the nut again, can realize quick dismantlement, and the check valve is usually sealed the opening, can prevent that dust impurity from entering into inside the nut, overall structure is simple and practical.

The utility model discloses further set up to: the check valve comprises a steel ball and a spring, a sealing plug is arranged at the position of the inner opening, the steel ball is arranged at the opening, one end of the spring is arranged in the cavity and connected with the sealing plug, and the other end of the spring is connected with the steel ball.

By adopting the technical scheme, when oil is not injected, the spring enables the steel ball to be arranged at the opening to seal the opening, when the oil is injected, the steel ball is pressed, the spring is compressed, and the oil can flow into the cavity from the opening, so that the oil injection is realized.

The utility model discloses further set up to: the flow guide mechanism is provided with a plurality of flow guide grooves, a sealing cavity communicated with the cavity is arranged on the end face, facing the cavity, of the sealing plug, and a plurality of overflow holes communicated with the flow guide grooves are formed in the side face of the sealing plug.

By adopting the technical scheme, when oil flows into the cavity, the oil enters the sealing cavity of the sealing plug, the side surface of the sealing plug is provided with the plurality of overflow holes, and the overflow holes are communicated with the diversion trench, so that the oil in the sealing cavity can flow into the diversion trench through the overflow holes and flows onto the threads along the diversion trench, lubrication is realized, and the nut is detached.

The utility model discloses further set up to: the diversion trenches are evenly distributed on the inner wall of the screw cap, and the number of the overflow holes corresponds to the number of the diversion trenches.

By adopting the technical scheme, each flow guide groove corresponds to each corresponding overflow hole, so that the oil is ensured to flow into the flow guide grooves, and the oil is prevented from flowing everywhere because the flow guide grooves flow down.

The utility model discloses further set up to: the sealing plug is made of rubber or metal.

By adopting the technical scheme, as long as the inner opening can be sealed, the sealing plug can be in threaded connection with the nut, and can also be pressed into the inner opening through a tool.

The embodiments of the present invention will be further explained with reference to the drawings.

Detailed Description

As shown in fig. 1-5, the technical solution adopted by the present invention is: the utility model provides a novel nut, including nut body 1, nut body 1's top be equipped with cavity 11, cavity 11 top is equipped with opening 12, the bottom is equipped with interior opening 13, be equipped with in the cavity 11 and open or sealed check valve 2 with opening 12, be equipped with between nut body 1's internal surface and the check valve 2 and lead the water conservancy diversion mechanism 3 of oil to nut body's screw thread. Cavity 11 has been set up at the nut top, and check valve 2 has been set up, set up guiding mechanism 3 on the inner wall, when dismantling the nut, can aim at opening 12 earlier towards cavity 11 oiling, owing to the check valve, consequently, can open opening 12, oil is injected and is flowed to screw thread department through guiding mechanism 3, lubricate the screw thread, then when dismantling the nut again, can realize quick dismantlement, and check valve 2 usually seals the opening, can prevent that dust impurity from entering into inside the nut, overall structure is simple and practical.

The check valve 2 comprises a steel ball 21 and a spring 22, a sealing plug 4 is arranged at the position of the inner opening 13, the steel ball 21 is arranged at the position of the opening 12, the spring 22 is arranged in the cavity 11, one end of the spring is connected with the sealing plug 4, and the other end of the spring is connected with the steel ball 21. When the oil is not filled, the spring 22 prompts the steel ball 21 to be arranged at the opening 12 to seal the opening, when the oil is filled, the steel ball 21 is pressed, the spring 22 is compressed, and the oil can flow into the cavity 11 from the opening 12 to realize the oil filling.

The flow guide mechanism 3 is provided with a plurality of flow guide grooves 31, the end surface of the sealing plug 4 facing the cavity 11 is provided with a sealing cavity 41 communicated with the cavity 11, and the side surface of the sealing plug 4 is provided with a plurality of overflow holes 42 communicated with the flow guide grooves 31. When oil flows into the cavity 11, the oil enters the sealing cavity 41 of the sealing plug 4, the side surface of the sealing plug 4 is provided with a plurality of overflow holes 42, and the overflow holes 42 are communicated with the guide groove 31, so that the oil in the sealing cavity 41 flows into the guide groove 31 through the overflow holes 42 and flows onto the threads along the guide groove 31, lubrication is realized, and the nut is detached.

The diversion trenches 31 are evenly distributed on the inner wall of the screw cap, and the number of the overflow holes 42 corresponds to the number of the diversion trenches 31. Each guiding groove 31 corresponds to each corresponding overflow hole 42, so that the oil is ensured to flow into the guiding groove, and the oil is prevented from flowing everywhere because the guiding grooves 31 flow downwards.

The sealing plug 4 is made of rubber or metal. The sealing plug can be screwed to the screw cap or pressed into the inner opening by a tool, as long as it can seal the inner opening 13.

The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited thereto, and any modification that utilizes the inventive concepts will be within the scope of the patent claims.
