Abstract
The utility model relates to a door of a transformer, in particular to a square manhole door with a novel sealing structure. The square manhole door comprises a square manhole door body with a threaded hole, and is characterized in that a groove for placing a sealing gasket is formed at the periphery of the square manhole door body. The utility model has the benefits that the problems of exposure and ageing of the sealing gasket are solved and the square manhole door with the novel sealing structure is attractive in appearance.
Description
Technical field
The utility model relates to the door of transformer, is a kind of square manhole door of novel sealing structure specifically.
Background technology
Existing transformer manhole door profile has circle, square branch; Design feature for circular manhole door is that seal groove is processed well; But because the arrangement space deficiency has limited the diameter of circular manhole door, so circular manhole door is not easy to operating personnel's use, hommization is not strong.Though and former square manhole door takes up space little and is convenient to operating personnel's use; But its seal form is the plain cushion structure, does not have seal groove, and this sealing structure pad is not hermetically sealed; Neither attractive in appearance; And seal washer partly is exposed in the air, of long duration is prone to agingly, influences the seal of manhole door.
Summary of the invention
In order to remedy the deficiency of prior art, the utility model provides a kind of square manhole door that can effectively protect the novel sealing structure of sealing gasket.
The utility model is realized through following technical scheme:
A kind of square manhole door of novel sealing structure comprises square manhole door body with threaded hole, and its special character is: be provided with the groove of placing sealing gasket around the said square manhole door body.
The square manhole door of this novel sealing structure is around square manhole door body, to be provided with the groove of placing sealing gasket, like this sealing gasket is placed in the groove; Prevent that rainwater from drenching; Sealing gasket is installed for ease, is avoided the groove seamed edge to scratch arm, the seamed edge of groove is round-corner transition; For the ease of processing, said groove has at least a limit to connect the edge to square manhole door body in the horizontal direction.
The beneficial effect of the square manhole door of the utility model novel sealing structure: adopt the square manhole door of this novel sealing structure not only to solve the aging problem of seal washer exposure, and good looking appearance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the partial enlarged drawing of I among Fig. 1;
Among the figure, 1, screwed hole, 2, square manhole door body, 3, groove, 31, horizontal groove.
Embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises with threaded hole 1 square manhole door body 2; It is characterized in that: be provided with the groove 3 of placing sealing gasket around the said square manhole door body 2; The seamed edge of said groove 3 is round-corner transition, and groove 3 has at least a limit to connect the edge to square manhole door body 2 in the horizontal direction.
When the square manhole door of this novel sealing structure is made; At upper and lower two rabbet planes of the square manhole door body flange Width horizontal groove 31 that is used to place sealing gasket of perforation together; Process the vertical groove 3 of vertical direction by these horizontal groove 31 feeds and withdrawing then; Finally accomplished the top and the bottom sealing, the rectangular recess 3 of both ends open.3 of the grooves of this structure have feed and withdrawing mouth in the horizontal direction; Imperforation on the vertical direction; In notch, catchment when avoiding like this raining, adopt the square manhole door of this hermetically-sealed construction to solve not only good looking appearance simultaneously, and solved the aging problem of seal washer exposure.
