Abstract
The utility model discloses an instrument shell sealing structure which comprises a shell body, a sheet-shaped sealing rubber gasket and a pressing plate, wherein the sheet-shaped sealing rubber gasket is arranged on the shell body; one end of the shell body is provided with an inward-concave stamping groove, and the corners of the stamping groove are provided with through holes; the sheet-shaped sealing rubber gasket is provided with a sealing step matched with the stamping groove, the sealing step is provided with a positioning buckle matched with the through hole, and the sheet-shaped sealing rubber gasket further comprises a sealing flange formed at the outer edge of the sealing step; the pressing plate is fixed with the shell body through screws, and the sheet-shaped sealing rubber gasket is clamped between the shell body and the pressing plate. The sealing structure of the instrument shell is matched with the stamping groove of the shell body through the sealing platform of the sheet-shaped sealing rubber gasket, and the sheet-shaped sealing rubber gasket is tightly pressed on the shell body through the pressing plate, so that the secondary sealing effect is achieved, the sealing effect is improved, and the service life of the instrument is prolonged.
Description
Technical Field
The utility model relates to an instrument, in particular to an instrument shell sealing structure.
Background
Generally, the industrial instruments are used in a harsh environment, and have high air humidity and much dust. The general instrument structure is used for a long time and is easy to cause short circuit and damage electronic components, thereby causing the instrument to work normally. Although the trompil department of conventional instrument shell all can set up seal structure, sealed glue is simple enough, receives the influence easily in adverse circumstances, and it is very easily droing after ageing, causes inside electronic components to expose the air, shortens the life of instrument.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a sealing structure of an instrument shell.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
an instrument case seal structure is characterized in that: the sealing device comprises a shell body, a sheet-shaped sealing rubber gasket and a pressing plate; one end of the shell body is provided with an inward-concave stamping groove, and the corners of the stamping groove are provided with through holes; the sheet-shaped sealing rubber gasket is provided with a sealing step matched with the stamping groove, the sealing step is provided with a positioning buckle matched with the through hole, and the sheet-shaped sealing rubber gasket further comprises a sealing flange formed at the outer edge of the sealing step; the pressing plate is fixed with the shell body through screws, and the sheet-shaped sealing rubber gasket is clamped between the shell body and the pressing plate.
Preferably, the positioning buckle is conical, and the outer diameter of the free end of the positioning buckle is matched with the through hole.
Preferably, the middle part of the sheet-shaped sealing rubber gasket is provided with a positioning column, and the middle part of the punching groove is provided with a positioning hole matched with the positioning column.
The technical scheme can obtain the following beneficial effects: the sealing structure of the instrument shell is matched with the stamping groove of the shell body through the sealing platform of the sheet-shaped sealing rubber gasket, and the sheet-shaped sealing rubber gasket is tightly pressed on the shell body through the pressing plate, so that the secondary sealing effect is achieved, the sealing effect is improved, and the service life of the instrument is prolonged.
Drawings
Fig. 1 is a schematic structural view of a meter case sealing structure according to a preferred embodiment of the present invention.
Detailed Description
The utility model is further illustrated by the following examples, which are not intended to limit the scope of the utility model.
As shown in fig. 1, the instrument case sealing structure in the present embodiment includes a case body 1, wherein one end of the case body 1 is provided with an inwardly recessed punching groove 11, and each corner of the punching groove 11 is provided with a through hole 12. Still including the sealed cushion 2 of slice that is used for sealed lid punching press groove 11, be equipped with on sealed cushion 2 of slice with punching press groove 11 assorted sealed step 21, sealed step 21 be equipped with the location buckle 22 of through-hole 12 adaptation, location buckle 22 is the toper in this embodiment, the external diameter of the free end of location buckle 22 and the internal diameter adaptation of through-hole 12. The sheet-shaped sealing rubber gasket 2 further comprises a sealing rib 23 formed on the outer edge of the sealing step 21, and the outer wheel size of the sealing rib 23 is larger than the outer contour size of the stamping groove 11.
The other side of the sheet-shaped sealing rubber mat 2 is provided with a pressing plate 3, and the pressing plate 3 is fixed with the shell body 1 through a screw 31, so that the sheet-shaped sealing rubber mat 2 is clamped between the shell body 1 and the pressing plate 3.
In order to improve the assembly type positioning and the assembly speed, a positioning column 24 is further arranged in the middle of the sheet-shaped sealing rubber gasket 2, and a positioning hole 111 matched with the positioning column 24 is arranged in the middle of the stamping groove 11.
During assembly, the positioning column 24 is aligned to the positioning hole 111, four corners of the sheet-shaped sealing rubber mat 2 are aligned to the through hole 12 to be extruded, and the conical positioning buckle 12 can be pressed into the through hole 12 to realize connection of the sheet-shaped sealing rubber mat 2 and the shell body 1. Then, the pressing plate 3 is pressed on the other side of the sheet-shaped sealing rubber gasket 2 and is fixedly connected with the shell body 1 through the screw 31.
While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the utility model, and these changes and modifications are within the scope of the utility model.
