Abstract
The invention provides a sealing door body of a box substation. The sealing door body comprises a box body and a box door, wherein the box door is arranged on the box body and provided with a door lock, the peripheral surface, facing the inner side, of the box body is provided with an L-shaped door frame, a contact position, facing the inner side, between the box body and the peripheral surface of the box door is provided with an U-shaped box frame, the box frame encircles the door frame, and a rubber sealing bar wraps the door frame and is in tight contact with the box frame. The sealing door body has the advantages of a simple structure, a reasonable design and a good sealing, dustproof and waterproof effect.
Description
Technical field
The present invention relates to case and become attached part field, especially relate to a kind of case and become hermatic door body.
Background technology
Case becomes box-type substation, a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment, by indoor, the outdoor close-coupled controller switching equipment of certain connection plan row's all-in-one-piece prefabrication, organically combine by functions such as high powered, transformer pressure-reducing, low-voltage distributions, be arranged on a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in steel construction casing, there is the problems such as the not good or hermetically-sealed construction of sealing effectiveness is too complicated in the chamber door of existing casing.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, reasonable in design, the good case change of sealing and dustproof waterproof effect hermatic door body.
Technical scheme of the present invention is:
A kind of case becomes hermatic door body, comprise casing and be arranged on described casing and with the chamber door of door lock, the surrounding end face of described chamber door is provided with L shaped door limit to the inside, the position that described casing contacts with the surrounding end face of described chamber door is provided with the case limit of U-shaped to the inside, described case limit surrounds described door limit, described door is enclosed with rubber weather strip, described rubber weather strip and described case limit close contact on limit.
Further, the junction of described case limit and described chamber door is circular arc.
Further, described door lock comprises handle, is arranged on the upper and lower locking bar of described handle and is enclosed within on described locking bar and is fixed on the locking bar guiding trestle on described chamber door, and the end of described locking bar bends to the inside and contacts with described case limit.
Advantage and good effect that the present invention has are: the L shaped structure of Men Bianwei, case limit is the U-shaped structure being enclosed on a limit, not only can strengthen mechanical strength and the rigidity of casing and chamber door, on door limit after environmental sealing bar, coordinate the outer end structure of chamber door and casing, prevent that dirt water from entering, and casing is flowed out on the L shaped limit that water can Yan Qimen limit surrounding.
