Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
The utility model discloses an aspect provides a steel construction single leaf protection sealing door, include: the door comprises a door leaf 1, a door frame 2, a hinge 3 and a locking mechanism 11, wherein the door leaf 1 is pivotally connected with the door frame 2 through the hinge 3, the door leaf 1 comprises an inner side panel 4, a framework 5 and an outer side panel 6, a hollow interlayer is formed between the inner side panel 4 and the outer side panel 6, the framework 5 and the locking mechanism 11 are arranged in the hollow interlayer, and the inner side panel 4 and the outer side panel 6 are different in thickness. More preferably, the thickness of the outer panel 6 is larger than that of the inner panel 4, and the door leaf is opened and closed by manual control.
In one embodiment, the latching mechanism includes a scroll plate, a worm, a linkage, an orientation slot, and a latch. The bolt is connected with the worm by a connecting rod, the connecting rod is arranged in the directional groove, and the door frame is provided with a lock box corresponding to the bolt. Of course, other configurations known in the art may be used.
In the technical scheme, the utility model provides an outside panel 6 both participates in whole atress under the load operating mode and as local atress component again, and inside panel 4 is main as maintaining the component, considers its whole atress effect when necessary.
Since the technical scheme is used, the utility model discloses a structural stress has been optimized to the panel design of non-uniform thickness, has alleviateed door leaf dead weight and cost, and airtight performance is reliable, the outward appearance is pleasing to the eye.
Preferably, the section of the framework 5 is U-shaped, and the framework 5 is arranged in a groined shape.
Preferably, the door leaf 1 includes a first region corresponding to the door frame 2 and a second region surrounded by the first region, and a thickness of the first region of the door leaf 1 is smaller than a thickness of the second region of the door leaf 1. That is, the door frame supports the door leaf, the section height is small, the section height of the middle part of the door leaf is high, and the section usually changes abruptly at a certain preset position. Therefore, the door leaf part can be embedded between the door frame and the door leaf by adopting the variable cross section form, and the possibility of out-of-plane sliding is avoided.
