Abstract

The utility model relates to a stopper structure of an oil pressure pipe, relating to a device for fastening or fixing components. The tail end of a pipe body of the oil pressure pipe is fixedly consolidated with a joint, and an inner screw part of the joint causes a stopper to be screwed with the joint. The inner part of the stopper is cylindrical, the outer end of the stopper forms a body, and in addition, the center of the body is in a hollow shape. A plurality of slip limiting parts are raised on an outer side edge of an outer body, the bottom surface of an inner part is provided with a bunting surface, the inner end of the body is provided with a converging part, and a screw part is arranged on the outer diameter of the converging part. The stopper structure of the utility model can reduce the accumulation of oil dirt and dust after the utility model is plugged and combined with the joint of the oil pressure pipe, and in addition, the oil dirt and the dust are easily eliminated.

Description

The chock plug structure of oil pressure pipe

The utility model relates to the device of fastening or fixed component.

Because lubricant oil may drip and ooze on the ground during oil pressure machining, or its oil stain bits ash is sprayed onto on each oil pressure pipe, and the chock plug inside that causes each joint outer end of each oil pipeline hoards thick greasy dirt, dust, be difficult to and please manage, its reason is to hoard not by the bad grease that causes of chock plug structural design of this oil pressure pipe, and easy to clean causes.

As Fig. 1,2 for a kind of chock plug structural representation of the oil pressure pipe of commonly using, body 1 a terminal affixed joint 2 of this oil pressure pipe, and the internal thread part 21 of mat joint 2 is bolted on the joint 2 this chock plug 3, and this chock plug 3 is cylindric, and body 31 inside of this chock plug 3 are hollow shape, inner moulding one external thread part 32, and these external thread part 32 sides of son are the one-body molded circular-arc prominent circle 33 that has, and make the interior container 34 that forms inner sealing, outer end opening of central authorities of chock plug 3; When being bolted in this joint 2, lie in this sheathed packing ring 35 in chock plug 3 outside threads 32 outsides and be the tightness that increases 2 of good this chock plug 3 and joints with chock plug 3; And owing to moulding one room 34 in these chock plug 3 structures, room 34 is dark and long, therefore through after using for a long time, will hoard many dusts, grease in the room 34, and the utmost point is not easy to clean.

The utility model purpose is: the chock plug structure that provides a kind of convenience please wash, not pile up the oil pressure pipe of grease again makes working environment clean and tidy.

The utility model is to realize like this, the chock plug structure of oil pressure pipe, it lies in the terminal fixed joint of body of this oil pressure pipe, the internal thread part of mat joint is bolted on the joint this chock plug, and chock plug includes the body and the inner shrinkage part of outer end, and the body external side brim is provided with the anti-slip section, and forms the screw section on the external diameter of shrinkage part, the inner bottom surface system of this chock plug body is shaped to one and supports face, and shrinkage part inwardly was permeable type from supporting the face place.

Though chock plug of the present utility model is identical with the purposes of commonly using product, but in using on the effect, because the body interior bottom surface of chock plug structure system is shaped to one and supports face, so its alcove that outwards forms is little and shallow far beyond the room of commonly using product, hence one can see that, and chock plug of the present utility model will significantly reduce the accumulation degree of dust, grease, even and have and pile up oil stain, dust and dirt, therefore the as easy as rolling off a log cleaning that will become, makes working environment comparatively clean and tidy.

The following drawings and embodiment will be described further the utility model technical characteristics:

Description of drawings:

The perspective exploded view of the chock plug structure of Fig. 1 conventional oil pressure pipe.

The assembling cross-sectional schematic of the chock plug structure of Fig. 2 conventional oil pressure pipe.

Fig. 3 is the perspective exploded view of the utility model structure.

Fig. 4 is the assembling cross-sectional schematic of the utility model structure.

Embodiment:

Shown in Fig. 3,4, chock plug 6 is the inner circular column, its outer end is formed with the body 61 that central authorities are hollow shape, and convex with some anti-slip sections 62 in the external side brim of body 61 system, and the inner bottom surface of body 61 system is shaped to one and supports face 63, makes it outwards form alcove 67, and the inner of body 61 is the one-body molded shrinkage part 64 that has, and shrinkage part 64 is inner from being permeable type in face 63 places, in addition, forms screw section 65 on the external diameter of shrinkage part 64; When chock plug 6 is assembled in oil pressure pipe, be to utilize its screw section 65 to be bolted in the internal thread part 51 of this joint 5 chock plug 6 and finish assembling, and in the also sheathed packing ring 66 in the outer top side of these chock plug 6 screw sections 65, use the tightness that increases 5 of good this chock plug 6 and joints.

Claims

A kind of chock plug structure of oil pressure pipe, it lies in the terminal fixed joint of body of this oil pressure pipe, the internal thread part of mat joint is bolted on the joint this chock plug, and chock plug includes the body and the inner shrinkage part of outer end, the body external side brim is provided with the anti-slip section, and form the screw section on the external diameter of shrinkage part, it is characterized in that: the inner bottom surface system of this chock plug body is shaped to one and supports face, and the inner face place that should support certainly of shrinkage part inwardly was permeable type.
