Abstract
The utility model discloses a sealing matching structure at the position of a well body and a top cover, which is characterized by comprising a well mouth, wherein the well mouth is in an annular convex shape; the well lid, the well lid lock is on the well head, and the bottom of well lid has the annular protrusion that is used for matching with the well head, and the cooperation of annular protrusion is in the inboard of well head, the annular protrusion one side laminating that is close to the well head be provided with the seal cushion layer. Through the matching structure who provides the gomphosis well head well lid of many echelonings, can realize on the basis of original airtight effect further reinforcing, current airtight efficiency to the cross-sectional shape of well head outer wall has been improved, makes it replace to the slope form, can be fine with the well lid fold.
Description
Technical Field
The utility model belongs to the field of sealing mechanisms, and particularly relates to a sealing matching structure at the position of a well body and a top cover.
Background
Along with the construction process of electric devices and automation devices in China, the construction and protection of the automation devices in the industries of electric power, communication, water conservancy and the like become a working key point.
Generally, the electrified device is packaged in a closed well body, the well body is embedded underground, but in the prior industry, how to solve the problem of sealing the well cover is still greatly diverged, a rigid extrusion mode is generally adopted for plugging, but the plugging method is difficult to construct and difficult to apply.
SUMMERY OF THE UTILITY MODEL
The utility model provides a sealing matching structure at the position of a well body and a top cover, which at least solves the problem that the well head cannot be effectively sealed in the prior art.
The technical scheme is as follows:
a sealing structure for the well body and the top cover comprises
The well head is in an annular convex shape;
the well lid, the well lid lock is on the well head, and the bottom of well lid has the annular protrusion that is used for matching with the well head, and the cooperation of annular protrusion is in the inboard of well head, the annular protrusion one side laminating that is close to the well head be provided with the seal cushion layer.
Furthermore, the outer diameter of the annular protrusion is smaller than that of the well lid, an annular corner area is formed between the outer side of the annular protrusion and the lower surface of the well lid, and a sealing cushion layer is attached to the corner area.
Further, be equipped with convex outer protrusion along the outer fringe of well lid, outer protrusion is concentric with the annular protrusion, forms between outer protrusion and the annular protrusion to be used for with well head top along complex recess.
Drawings
The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the utility model and together with the description serve to explain the utility model without limiting the utility model.
FIG. 1 is a side view of the seal of the present invention.
FIG. 2 is an exemplary view of a seal cross-sectional structure of the present invention.
Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1, as shown in FIGS. 1-2, there is provided a seal engagement structure at a well body and header location, comprising
The well head is in an annular convex shape;
well lid 1, the well lid lock is on well head 2, and the bottom of well lid has the annular protrusion that is used for matching with the well head, and the cooperation of annular protrusion is in the inboard of well head, the annular protrusion one side laminating that is close to the well head be provided with the seal cushion layer.
The convex external diameter of annular is less than the external diameter of well lid, and the convex outside of annular forms annular turning district with well lid lower surface, has attached to the seal cushion layer in the turning district.
The main improvement of the utility model is that: through the matching structure who provides the gomphosis well head well lid of many echelonings, can realize on the basis of original airtight effect further reinforcing, current airtight efficiency to the cross-sectional shape of well head outer wall has been improved, makes it replace to the slope form, can be fine with the well lid fold.
Example 2, as shown in FIGS. 1-2, there is provided a seal engagement structure at a well body and header location, comprising
The well head is in an annular convex shape;
well lid 1, the well lid lock is on well head 2, and the bottom of well lid has the annular protrusion that is used for matching with the well head, and annular protrusion cooperation is in the inboard of well head, annular protrusion be close to one side laminating of well head and be provided with the seal cushion, and be equipped with convex outer protrusion along the outer fringe of well lid, outer protrusion is concentric with the annular protrusion, forms between outer protrusion and the annular protrusion to be used for with the well head top along the complex recess.
The outer wall surface of the well mouth rises in a slope shape, the inner surface which is matched with the outer wall and protrudes outwards is a matched slope, and the outer wall surface of the well mouth and the inner surface which protrudes outwards are matched with each other to form isolation.
As shown in fig. 1 and 2, the outer diameter of the annular protrusion is smaller than that of the well lid, an annular corner area is formed between the outer side of the annular protrusion and the lower surface of the well lid, and a sealing cushion layer is attached to the corner area.
Or a sealing cushion layer or a glue interlayer is attached to the groove bottom of the groove.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
