Description

Gasket for pipe fitting and general machine thereof

Technical Field

The utility model relates to a packing ring field especially relates to a connection and fastening components of pipe fitting.

Background

At present, parts such as panels of general mechanical products such as generators, water pumps, mini-tillers and mowers penetrate through the panels and the frame pipes through bolts and are matched with nuts to be tightly fixed on the frame pipes, the nuts are directly contacted with arc parts of the frame pipes, contact surfaces are small, anti-falling structures do not exist, when a generator set runs, loosening failure can be caused between the nuts and the frame pipes due to vibration, and further parts fixed by the bolts are loosened to influence normal use; in addition, parts such as the panel are in direct contact with the arc part of the frame pipe, the contact surface is small, in order to increase the contact area between the parts such as the panel and the pipe fitting, the contact surface between the parts such as the panel and the pipe fitting is made into a pipe profile or the pipe fitting is flattened in the prior art, and the methods are high in cost and complex in process, and cannot solve the problems that the pipe fitting deforms, the parts and the pipe fitting move relatively and the like when the parts are fastened.

At present often adopt the packing ring to adjust above-mentioned problem, but current packing ring is the part of thickness uniformity, can not solve above-mentioned problem, consequently needs to increase one between nut and pipe fitting, spare parts such as pipe fitting and panel between be connected and fastening part, solves the fixed connection problem of spare parts such as panel, makes the convenient fixed connection of spare parts such as panel on the pipe fitting, and is difficult to become flexible, drop.

The utility model discloses the content

In order to realize the aforementioned purpose, to the spare part better with the pipe connection fastening, the utility model provides a packing ring for pipe fitting, the packing ring material can be plastics or metal, the packing ring is the annular, and there is a through-hole at its center, a packing ring terminal surface is the plane, another terminal surface be with pipe fitting complex arcwall face. The thickness of the gasket from the plane end to the highest point of the cambered surface is more than 0.5cm, and the thickness of the gasket is increased, so that one end face of the gasket is made into the cambered surface matched with the pipe fitting. When the packing ring is matched with the pipe fitting, the arc-shaped surface is attached to the pipe fitting, the contact surface between the pipe fitting and the packing ring is increased, and meanwhile, the packing ring is not easy to move relative to the pipe fitting. The plane at the other end of the gasket is contacted with the part to be matched, so that the mounting surface of the part can be directly made into a plane without being made into an arc-shaped surface, the processing difficulty of the mounting surface of the part is reduced, the manufacturing cost is reduced, and the gasket can be matched with a pipe fitting to be mounted more easily; when the washer is matched and fastened with the nut, the plane of the nut is contacted with the plane of the washer, the nut is fastened simply, and the pipe fitting fastened with the nut through the washer is stressed uniformly and is not easy to fall off.

Further, the washer plane end has the lock tooth structure, and this lock tooth structure arranges along the washer plane outer lane, and is opposite with the lock tooth structure of nut, and when the cooperation of packing ring arc surface and pipe fitting, the nut was fastened with the bolt cooperation that passes pipe fitting and packing ring, and the packing ring plane is in close contact with the nut plane, and the lock tooth structure of packing ring is the same with the lock tooth structure tooth number on the nut, and the direction of rotation is each other for opposite, and if the packing ring lock tooth structure can be dextrorotation, and is the same with the clockwise that the nut was screwed, the lock tooth structure of nut is the levogyration. After the washer and the nut are screwed down, the nut can be firmly locked, the nut is prevented from loosening, and the parts are ensured to be in a normal working state.

Further, the gasket protrudes outwards from the center of the arc-shaped end face to form a circular mandrel with the diameter smaller than the outer diameter of the gasket; the central hole of the gasket penetrates through the mandrel, when the gasket is matched with the pipe fitting, the cambered surface of the gasket is contacted with the pipe fitting, the mandrel penetrates through the through hole of the pipe fitting, so that the gasket and the pipe fitting do not move relatively, the pipe fitting does not need to be flattened to adapt to the gasket by adopting the gasket, the manufacturing process of the pipe fitting is reduced, and the deformation of the pipe fitting during fastening is reduced.

Further, the general machine adopting the gasket can be a generator, a water pump, a mini-tiller, a mower and the like, the general machine has a pipe fitting handrail or a tubular frame, parts are often mounted on the general machine, for example, a panel, a travelling wheel and the like need to be fixedly mounted on the pipe fitting frame of the generator, the water pump and the like, and an operation panel, a switch and the like need to be mounted on the pipe fitting handrail of the mini-tiller, the mower and the like. The parts can be fixedly connected with the pipe fitting through bolts, nuts and the washers. The parts and the pipe fitting are more easily matched and tightly connected through the gasket; increase the area of contact of nut and pipe fitting simultaneously, through bolt and nut fastening cooperation back, the same number of teeth of packing ring and nut revolves to the lock tooth structure that each other is opposite and plays, prevents that the nut pine from taking off, has guaranteed the stability of spare part, and the arc structure and the central protruding dabber mechanism of packing ring have simultaneously further prevented the relative movement between spare part and the pipe fitting, and the pipe fitting is out of shape when preventing fastening bolt.
