Description

Fire-proof door

Technical Field

The utility model belongs to the technical field of the technique of building door body and specifically relates to a prevent fire door.

Background

Because the earthquake frequently occurs and has no predictability, the people can not exactly know when the earthquake occurs, and the people are generally indoors when the earthquake occurs, the common solution is to adopt a firmer building structure to avoid the great damage to the human body caused by the collapse of the earthquake building.

The existing earthquake-resistant door body structure is generally a layer structure or a shear structure, once the earthquake intensity is high, the building can collapse when the load is not up, so that the damage is caused, and the earthquake-resistant door body structure is not firm enough. Therefore, when an earthquake occurs, people generally select the corner close to the fireproof door to avoid shock, but the human body damage caused by huge objects flying transversely during the earthquake is difficult to avoid.

Therefore, there is a need to develop a fire door with anti-seismic function.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a perfect shock absorber structure falls in door body angle.

The method is realized by the following technical scheme:

a fireproof door comprises a door frame and a door body hinged on the door frame, wherein the door body comprises a first door body and a second door body hinged with the first door body; a plurality of triangular blocks are arranged at one end of the first door body close to the second door body; one side right-angle edge of the triangular block is fixed with the first door body, and the other side right-angle edge of the triangular block faces the second door body; a plurality of driving devices for driving the second door body to rotate towards the wall body are arranged on one side, close to the second door body, in the first door body; a stretchable connecting piece is further arranged between the first door body and the second door body; a plurality of iron hooks are arranged on one side of the second door body, which is far away from the first door body; a plurality of iron rings matched with the iron hooks are arranged on the wall body close to the first door body; a rolling part used for moving the second door body is also arranged at the bottom of the second door body; and fireproof damping layers are arranged in the first door body and the second door body.

Through adopting above-mentioned technical scheme, when need moving away to avoid possible earthquakes, get into rapidly and prevent that fire door uses drive arrangement drive second door body to rotate towards first door body under the cooperation of rolling member, when the right-angle side butt of the second door body and three hornblocks, and then first door body and second door body rotate towards the wall body together. The hook iron ring is tightly hooked by the iron hook, so that the second door body is tightly connected with the wall body, and a stable triangular structure is formed. The triangular door body is beneficial for a shock absorber to enter the structure enclosed into a triangle, when a building collapses, the gravity of a roof falling on objects or furniture can impact the objects, so that a space is left at a position close to the objects, and the space is the triangular door body formed by combining the wall body, the first door body and the second door body. But connect the tensile connecting piece between the second door body and the first door body and be favorable to guaranteeing the steadiness between the second door body and the first door body, the cooperation of iron hook and hoop is favorable to guaranteeing the steadiness between the second door body and the wall body, because the second door body and first door body mutually perpendicular, therefore so the hoop is buckled mutually, and the three encloses into a comparatively inclosed triangle form door body each other, has higher shock attenuation effect. In addition, the door body formed by enclosing effectively resists objects impacted in different directions, and great damage is avoided. The fireproof damping layer arranged in the first door body and the second door body is favorable for reducing the vibration and fireproof effects brought by earthquake, and the protection performance of the door body structure is further improved.

The utility model discloses further set up to: the driving device is a single-action cylinder, and the end part of a piston rod of the single-action cylinder is abutted against the second door body.

Through adopting above-mentioned technical scheme, start the single-action cylinder, the piston rod of single-action cylinder is extruded by first door body towards the second door body this moment, orders about the second door body and rotates towards the wall body, and then forms the triangle-shaped door body between messenger's wall body, the first door body and the second door body.

The utility model discloses further set up to: the tensile connecting piece is a large thick iron chain.

Through adopting above-mentioned technical scheme, the effectual steadiness of guaranteeing between the first door body and the second door body of big thick iron chain avoids making between the first door body and the second door body to drop easily after the second door body rotates, and then causes the unstable structure of wall body, the first door body and the second door body after enclosing each other and closing.

The utility model discloses further set up to: the rolling piece is an iron ball with a smooth surface.

Through adopting above-mentioned technical scheme, smooth iron ball in surface slides subaerial when being favorable to the second door body to rotate, avoids the second door body to rotate not smooth and easy enough, leads to using more time to the second door body and wall body combination, has wasted more time and has increased the risk that the earthquake brought.

The utility model discloses further set up to: the fireproof damping layer is arranged on the outer base layer on two sides of the first door body and the second door body.

Through adopting above-mentioned technical scheme, the vibrations that bring for the first door body and the second door body when setting up effectual buffering earthquake of fire prevention shock-absorbing layer are favorable to keeping wall body, the first door body and the second door body three to enclose the firm structure that closes the formation triangle form door body, have further strengthened the shock attenuation effect of this structure.

The utility model discloses further set up to: the fireproof shock absorption layer is a perlite layer embedded with a spring.

Through adopting above-mentioned technical scheme, the fire prevention buffer layer has the fire prevention effect of pearlite, makes door body structure have the guard action, takes place the personnel of moving away to avoid possible earthquakes of conflagration damage in the door internal when avoiding the earthquake, the impact force that brings for the door body when the effectual buffering earthquake of the spring of embedded in addition.

The utility model discloses further set up to: the fireproof shock absorption layer is also distributed with elastic rubber micro-beads.

Through adopting above-mentioned technical scheme, when the earthquake goes on, because the impact force of violent vibrations area for door body structure, the elastic rubber microballon that sets up can produce effectual elastic deformation, and the effectual energy storage buffering that carries on has further improved door body structure's shock attenuation effect.

The utility model discloses further set up to: the fireproof door further comprises a handle, and the handle is arranged on one side, far away from the first door body, of the second door body.

Through adopting above-mentioned technical scheme, when the second door body needs to rotate, use the rotation of the second door body of being convenient for more of handle, the handle setting is kept away from first door body one side at the second door body moreover, and when the second door body was pulled, because the power arm is great to can be more laborsaving during feasible pulling second door body.

To sum up, the utility model discloses a beneficial technological effect does:

1. when an earthquake happens, the fireproof door can quickly form a triangular shock-absorbing door body structure with a wall body, so that the damage caused by the earthquake is effectively prevented;

2. first, the effectual shock attenuation performance that has strengthened a body structure of the fire prevention buffer layer that sets up in the door body to have good fire prevention effect, have many-sided guard action.
