Technical Field

The invention relates to the technical field of steel structure doors, in particular to a steel structure door with high safety and stable structure.

Background

The steel structure is a structure formed by steel materials, is one of main building structure types, and mainly comprises steel beams, steel columns, steel trusses and other members made of section steel, steel plates and the like, wherein all the members or components are usually connected by welding lines, bolts and rivets.

Current steel construction door receives high temperature easily when the conflagration breaing out and influences the deformation, leads to door or door frame to warp the back and can't open to the influence is fleed and is caused the security not high, and current steel construction door exists the relatively poor problem of stability simultaneously, for this reason, provides a security height and stable in structure's steel construction door.

Disclosure of Invention

The present invention is directed to a steel structure door with high safety and stable structure to solve the problems of the related art.

In order to achieve the purpose, the invention provides the following technical scheme: a steel structure door with high safety and stable structure comprises a first barrel, wherein a rear panel and a front panel are fixed at two ends of the first barrel respectively, a guide pipe is fixed at the outer side of the first barrel, a support rod penetrates through the inner side of the guide pipe, one end of the support rod is hinged to one side of a corner protector, slots are formed in two side sides of the corner protector, a first connecting rod and a second connecting rod are hinged to two parts of one side of the support rod respectively, one side of the first connecting rod is hinged to the outer side of the second rod, one side of the second rod and one side of the second connecting rod are inserted into the slots respectively, one side of the second connecting rod is hinged to the outer side of the first rod, a groove is formed in the end part of the other side of the support rod, the inner side of the front panel is rotatably connected with a second barrel through a bearing, a convex block is fixed on the outer side of the second barrel, a spring, swing joint has the inserted bar that runs through the lug in the spring holding tank, in the recess was inserted to the one end of inserted bar, second barrel internal thread connection has the threaded rod, the one end of threaded rod is fixed with the toper piece, the outside laminating of toper piece is in the other end of inserted bar.

Preferably, both ends of the first rod body and the second rod body are fixed with U-shaped steel plates, and the outer sides of the U-shaped steel plates are attached to the inner sides of the slots.

Preferably, a guide pipe is fixed on the outer side of the first cylinder, and the guide pipe is sleeved on the outer side of the support rod

Preferably, one end of the supporting rod is provided with a sliding groove, and the convex block slides on the inner side of the sliding groove.

Preferably, a second hand wheel is fixed on one side of the second cylinder, and a first hand wheel is fixedly connected on one side of the threaded rod.

Preferably, the inserted link is located inside one side of spring holding tank and is fixed with the stopper, one side of stopper passes through spring coupling in the inboard bottom of spring holding tank

Compared with the prior art, the invention has the beneficial effects that: according to the steel structure door, the first hand wheel is screwed, the threaded rod moves outwards to drive the conical block to be separated from the inserting rod, the inserting rod is not inserted into the groove any more, then the second hand wheel is rotated to drive the second barrel to rotate, the lug is not abutted against the supporting rod any more, and after the supporting rod loses the abutment of the lug, the first rod body and the second rod body can move freely, so that the first rod body and the second rod body can move within a certain range, the fit tightness with a door frame is reduced, people can conveniently open the door, and the escape safety is improved; the first rod body and the second rod body are respectively supported by the support rod through the second connecting rod and the first connecting rod, so that the steel structure door is more stable and is not easy to shake; the U-shaped steel plate can prevent the first rod body and the second rod body from shaking.
