Background

The department of economy of the fire department designates the approved laboratory, tests the fire resistance test method to pass according to the new version fire protection national standard GB _12955 one 2008, fire protection , which is implemented from 1 month 1 year 2009, and obtains the certification and certification of the accreditation of the institute of standards inspection of the department of economy, called fire protection . the fire protection defined by the US NFPA and IBC code is "any combination of fire protection fans, frames, hardware and other fittings that can provide a certain degree of fire protection at the opening together.

At present, the handle of the fireproof on the market is difficult to fold, and when people escape, the escape of the people can be blocked and the life of the people is threatened because the handle of the fireproof protrudes out of the surface of the body, so that the types of handle folding fireproof are designed to solve the problems.

Disclosure of Invention

The invention aims to provide kinds of handle folding fireproof , which solves the problem that the existing handle is difficult to fold by combining a backing plate, an opening and closing assembly and a stretching assembly.

In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to handle folding type fireproof which comprises a 3 body, wherein a 1 placing groove is formed in the surface of 0 of the body, 4 arc-shaped grooves are formed in 2 opposite inner walls of the placing groove, backing plates are fixedly installed at the top and the bottom of the placing groove, -th sliding grooves are formed in opposite inner walls of the two backing plates, opening and closing components are rotatably connected to the top and the bottom of the placing groove and located on the front sides of the backing plates, the opening and closing components are connected with bodies through snap springs, and stretching components are slidably connected between the two opening and closing components;

the opening and closing assembly comprises an side plate, a second sliding groove is formed in the surface of the side plate, a limiting hole is formed in the second sliding groove, and a rectangular groove is formed in the inner wall of the limiting hole;

the stretching assembly comprises an fixing barrel, the inside of the fixing barrel is connected with two limiting rods in a sliding mode, the end of each limiting rod is located inside a limiting hole, and a spring is arranged between the limiting rods.

, the arc-shaped groove is positioned in the middle of the placing groove and is of a quarter cylinder shape.

, the sliding groove is communicated with the second sliding groove, the sliding groove is the same as the second sliding groove in width, and the sliding groove and the second sliding groove are the same as the limiting rod in diameter.

, a third sliding groove is formed in the fixed cylinder, a sliding block is fixedly mounted on the peripheral side face of the limiting rod, and the sliding block is located in the third sliding groove and is in sliding fit with the third sliding groove.

, the end of the limiting rod is an arc surface which is smooth.

The invention has the following beneficial effects:

according to the invention, the body can be opened by holding the fixing barrel by hand, after the body is opened, in order to prevent the fixing barrel from obstructing escape of an escape person, at the moment, the limiting rod is pressed by fingers, due to the action of the spring, the part of the limiting rod can be contracted into the fixing barrel, at the moment, the fixing barrel is pushed inwards, so that the limiting rod slides inwards along the second sliding groove until the stretching assembly is positioned between the two backing plates, and because the opening and closing assembly is connected with the body through the snap spring, the two opening and closing assemblies are closed and flush with the front surface of the body after being closed, so that , the front surface of the body has no projection, so that the escape person is prevented from being obstructed by a handle, in addition, when the stretching assembly needs to be opened, two fingers are placed in the arc-shaped groove, and then the stretching assembly is pulled outwards until the top end of the limiting rod is.

Of course, it is not necessary that achieve all of the above-described advantages at the same time for any product that embodies the invention.
