Description

Bolt easy to lock and disassemble

Technical Field

The utility model relates to a bolt technical field especially relates to an easily bolt of locking dismantlement.

Background

Bolts are widely used for the connection between parts as mechanical connectors. Usually, the bolt head on the screw rod can be fixed by a spanner when the nut is screwed, so that the screw rod cannot rotate when the nut starts to be screwed. And under some operating conditions, for example, power equipment in the air, wherein also use bolted connection spare, the operation is inconvenient this moment, is not convenient for vacate two hands simultaneously and turns round a bolt usually, and when the nut began to screw, the bolt was followed the nut easily and is rotated together for the nut can not once only be screwed, has prolonged operating time, and work efficiency is low, and after long-time the use, the bolt was fixed together because of rustting easily, and it is convenient inadequately to dismantle.

Chinese patent document CN203051389U discloses a pre-tightening type easily detachable bolt, which includes a bolt head and a screw rod, wherein a step is arranged on the lower end face of the bolt head, an annular groove is arranged between the step and the edge of the lower end face of the bolt head, the upper end of the screw rod is a polished rod section, the lower end of the screw rod is a threaded section, a gasket is sleeved on the polished rod section, a spring is connected between the gasket and the bolt head, the upper end of the spring is clamped in the annular groove, and a shallow groove parallel to the axis of the screw rod is arranged. The utility model discloses simple structure, convenient to use has prevented effectively that the bolt from following the emergence of the rotatory phenomenon of nut, has improved work efficiency, adopts the design that sets up the shallow slot on the screw thread section of screw rod, when the bolt is difficult for dismantling because rust, can follow shallow slot and join lubricating oil to the dismantlement operation has been made things convenient for effectively. The above structure has disadvantages in that: because the shallow groove is arranged on the surface of the screw rod, the depth of the shallow groove is shallow, and the shallow groove cannot be quickly soaked between the screw rod and the nut when lubricating oil is added, so that the disassembly time is long.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned technique, provide an easily bolt of locking dismantlement, can prevent that bolt and nut from together rotating, convenient fastening also can be convenient for lubricate the junction of nut and bolt, convenient dismantlement.

In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:

a bolt easy to lock and disassemble comprises a bolt body and a nut matched with the bolt body, wherein the bolt body comprises a screw rod and a bolt head integrally formed with the screw rod; the outer surface of the screw is provided with a shallow groove parallel to the axis of the screw, the other end face of the screw opposite to the bolt head is provided with an oil filling hole channel along the central axis, the shallow groove is provided with a plurality of oil guide holes, and the oil guide holes are communicated with the oil filling hole channel.

The utility model discloses a further improvement lies in, the bolt head is hexagonal bolt head, and the nut is hexagon nut.

The utility model discloses a further improvement lies in, the sand grip surface is formed with the spiral line, further improves and by the frictional force between the connecting element.

The utility model discloses a further improvement lies in, the external diameter of gasket is greater than the external diameter of bolt head, and gasket and bolt head be the integrated into one piece structure.

The utility model discloses a further improvement lies in, the sand grip melts the shaping structure for the welding wire.

The utility model discloses a further improvement lies in, the shallow slot is equipped with a plurality ofly to along screw rod circumference interval equipartition.

The utility model has the advantages that: the utility model discloses a gasket, sand grip and spiral line combination, when the bolt is connected with the nut, the gasket supports tightly on the part surface of being connected for frictional force increases, and with the screwing of nut, frictional force is bigger, has prevented effectively that the bolt from following the emergence of nut rotation phenomenon; the utility model discloses a set up and refuel the pore, through to refueling pore injection lubricating oil, lubricating oil gets into the shallow slot fast through leading the oilhole, can dismantle convenient to nut to the screw thread quick lubrication of screw rod.
