Abstract
The utility model provides a riveting type fabrication hole plug. The riveting type fabrication hole plug comprises a plug body and an O-shaped sealing ring. The O-shaped sealing ring is arranged in a groove prefabricated in the plug body, and the plug body is arranged in a fabrication hole; the inner diameter of the O-shaped sealing ring is in a drawing state in the groove of the plug body and in a compression state in the fabrication hole; and the plug body is riveted on a machine body. Compared with a common plug, the riveting type fabrication hole plug is characterized in that the O-shaped sealing ring is additionally arranged on a proper position of a common cylindrical plug, and sealing on the fabrication hole is achieved through riveting process, interference fit between the plug and the fabrication hole and sealing effect of the O-shaped sealing ring. The riveting type fabrication hole plug is applied to plugging of long holes, and applied specifications of the fabrication holes can reach 2.5mm to the minimum.
Description
Technical field
The utility model relates to a kind of riveted type auxiliary hole plug, is applicable to the obstruction of auxiliary hole in the hydraulic element production.
Background technique
Make the field at hydraulic element, often need make auxiliary hole, to realize the connection between the different ducts, the technology aperture need be stopped up usually, the sealing configuration that widely uses in this field at present comprises the screw plug of taper screw plug, various seal form, the screw plug of these two kinds of structures can satisfy general seal request, yet, all there are some shortcomings separately, cone blocking can't guarantee reliable sealing, the screw plug head installation dimension of other structures is bigger, thereby influences the structural design of hydraulic element.
The model utility content
The utility model provides a kind of riveted type auxiliary hole plug at above-mentioned the deficiencies in the prior art, and this riveted type auxiliary hole plug had both had good seal action, had less installation dimension again.
The utility model is achieved by the following technical solution:
A kind of riveted type auxiliary hole plug comprises plug body and O-ring seals, and O-ring seals is installed in the groove prefabricated on the plug body, and the plug body is installed in the auxiliary hole; The internal diameter of O-ring seals is in extended state in the groove of plug body, be in compressive state in auxiliary hole; Described plug body is riveted on the body.
Further, the stretch rate of O-ring seals is between 0～5%.
Further, between the inner end of plug body and the auxiliary hole be Spielpassung.
Further, between the outer end of plug body and the auxiliary hole be interference fit.
Riveted type auxiliary hole plug described in the utility model is different with common screw plug, be that suitable position at common cylinder body plug has added O-ring seals one, by the interference fit between riveting process and plug and the auxiliary hole and the seal action of O-ring seals, realized the shutoff to auxiliary hole reliably.The riveted type auxiliary hole plug that the utility model relates to is applicable to the shutoff of elongated hole, the auxiliary hole specification that is suitable for, and I reaches 2.5mm.
Description of drawings
Fig. 1 is the structural drawing of riveted type auxiliary hole plug described in the utility model;
Fig. 2 is riveted type auxiliary hole plug described in the utility model schematic representation in working order;
The implication of each label is as follows among the figure:
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the utility model provides a kind of riveted type auxiliary hole plug, comprises plug body 1 and O-ring seals 2, and O-ring seals 2 is installed in the groove prefabricated on the plug body 1, and the position of groove can arrange arbitrarily according to actual needs.Plug body 1 is installed in the auxiliary hole 4, and the cylndrical surface of auxiliary hole 4 is sealing surfaces; The internal diameter of O-ring seals 2 is in extended state in the groove of plug body 1, be in compressive state in auxiliary hole 4.Meanwhile, described plug body 1 is riveted on the body by special tool, thereby can prevent effectively that high pressure from getting plug, thereby has realized the shutoff to auxiliary hole 4 reliably.The internal diameter of O-ring seals 2 is in extended state in the groove of plug body 1, its stretch rate is between 0～5%.
The utility model not only is confined to above-mentioned embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple embodiment to implement the utility model; therefore; every employing project organization of the present utility model and thinking; do some simple designs that change or change, all fall into the scope of the utility model protection.
