Description

Technical Field

[0001] The invention relates to the technical field of fireproof doors for escape wells, in particular to a fireproof door for escape wells. Background Art

[0002] At present, the escape doors in the existing technology generally use the ordinary baffle opening and closing principle, and have been widely used in pipeline systems, but there are many obvious defects: for example, the transmission mechanism of the escape door is a connecting rod swing structure design, which has the defects of inaccurate switching and cannot be accurately opened when the pressure in the channel changes; when a mine disaster occurs, the underground environment is very harsh and may be accompanied by gas leakage or explosion; when an explosion occurs, if the transmission mechanism cannot be immediately started to open the escape door, the escape door cannot be opened, which directly affects the escape and rescue of the refugees. Summary of the invention

[0003] The object of the present invention is to provide a fireproof door for an escape shaft to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] The present invention provides a fireproof door for an escape well, comprising a rotatably connected door frame and a door leaf, wherein the door frame is fixedly installed at the end of the escape well mouth, hydraulic support rods are arranged on two opposite sides of the door frame, one end of the hydraulic support rod is rotatably connected to a fixed position of the door leaf, and the other end is rotatably connected to a fixed position of the door frame, and a push-lock rod is arranged on the side of the door leaf facing the escape well, and the push-lock rod can be inserted into the door frame.

[0006] As an improvement, the horizontal push locking rod is parallel to the hydraulic support rod.

[0007] As an improvement, the door frame and the door leaf are rotated by two stainless steel hinges.

[0008] Compared with the prior art, the advantages of the present invention are: simple structure, fire prevention and convenient escape, simple and accurate operation during escape, and after the horizontal push lock rod is opened, the hydraulic support rod directly props the door leaf open. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings listed below are only some structural schematic diagrams of the present invention, not all of them.

[0010] Figure 1 It is a structural schematic diagram of a fire door for an escape well of the present invention.

[0011] Figure 2 The present invention is an inner view of a fire door of an escape well.

[0012] Figure 3 The present invention is an external view of a fire door for an escape well.

[0013] Reference numerals:

[0014] Door frame 1; door leaf 2; escape well end 3; hydraulic support rod 4; push lock rod 5; stainless steel hinge 6; DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the indicated orientation or position relationship is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] In addition, if the terms "first", "second", "third", etc. appear, they are only used to distinguish the description and cannot be understood as indicating or implying relative importance. If the terms "horizontal", "vertical", "overhanging", etc. appear, it does not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and it does not mean that the structure must be completely horizontal, but can be slightly tilted.
