Abstract
The utility model relates to the technical field of manhole doors of engineering devices, which is designed for flexible and convenient open and closure. The utility model comprises a door cover, a door opening and a door frame and is characterized in that a door frame body is formed by connecting a convex wall plate with the door frame by using screw nails, the door cover is in the shape of a conical bottle cork, and heat insulating and preserving material is arranged in an inner concave cavity of the conical bottle cork; one side of the door frame body is movably connected with a rotating arm on a rotating arm frame through a shaft, the middle part of the rotating arm is connected with the door cover in a shaft mode, and a locking device is arranged between the door cover and the rotating arm. The utility model has the advantages of heat prevention and insulation and flexible open and closure and is not easy to deform. The utility model is suitable for being used on boilers, hot air channels, etc.
Description
The utility model relates to a kind of boiler, hot-flow flue and corollary equipment or the required design library part editor and reuse door to access technical field of engineering equipment.
Employed boiler, hot-flow flue and corollary equipment or other engineering equipment will often be checked, keep in repair and maintain it in some factories or the system, and when carrying out these work, people can operate by door to access.Employed door to access mostly was made up of along the supporting walls and the seal of framework door opening framework and fixed gate that door closure and door closure are complementary in some factories or the unit in the past, a kind of door to access appears again recently, Chinese utility model patent specification as the CN2307096y of on February 10th, 1999 bulletin, a kind of door to access with safety device is disclosed, it is used for the pressurization storehouse of pressing filter, mainly realize inside and outside the pressurization storehouse, can opening the purpose of door by the members such as conduit of inboard, to ensure the life security of being closed the people in the pressurization storehouse, though this door to access has it to ensure the advantage of being closed the life security of the people in the pressurization storehouse by mistake, but it uses manual operation, use effort, inconvenient, undesirable because of its thermal and insulating performance again, so the scope of application is narrow.
The purpose of this utility model is to provide that a kind of sealing heat-proof quality is good, open and close is very convenient, and is not yielding, and design library part editor and reuse door to access easy for installation.
For achieving the above object, the technical solution of the utility model is achieved in that this project device door to access includes door closure, the door opening of opening on the design library part editor and reuse, door opening is fixed with the doorframe support body, door closure one side and doorframe framework are for flexibly connecting, and contact surface is lined with seal between door closure and the door opening, it is characterized in that described doorframe support body is that the convex wallboard is connected with screw with doorframe and forms, door closure is a taper bottle stopper shape, and the interior depression at the taper bottle stopper is furnished with heat preserving and insulating material, doorframe support body one side is on the pivoted arm frame, flexibly connect pivoted arm with axle, also be connected with door closure outside fixed block in the middle of the pivoted arm, and also be provided with locking device between door closure and the pivoted arm with axis structure.
As the further improvement of technology, described doorframe and door closure contact-making surface have two dovetail annular grooves and inner ring dovetail annular groove, liner asbestos sealing ring.
As improving again of technology, the heat preserving and insulating material of arranging in the depression in the described taper bottle stopper shape is welding V-arrangement holdfast and irritates alumina cement that this heat preserving and insulating material can also be the alumina silicate heat-preservation cotton certainly.
Adopt the design library part editor and reuse door to access of this spline structure, heat preserving and insulating material is arranged and the seal of dovetail groove structure is arranged because door closure is taper bottle stopper shape and its internal placement, make it that good sealing and heat preservation and insulation be arranged, again because described doorframe framework and described convex wall-panels supports wall are connected to become the doorframe support body with screw, therefore this door to access has not yielding, easy for installation, again because adopted whirling arm mechanism, so guaranteed described door closure not only convenient successfully open or close or enter but also can make described door closure combine the plane with described doorframe framework to align subsides voluntarily close, make easy to operate, and it is safe and reliable.
