Technical Field

The utility model relates to a prevent fire door technical field, concretely relates to fire prevention access door based on 304 stainless steel. Background

A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. The fireproof partition is arranged in fireproof partitions, evacuation staircases, vertical shafts and the like and has certain fire resistance, and the fireproof door has the functions of preventing fire from spreading and smoke from diffusing besides the function of a common door, can prevent the fire from spreading within a certain time and ensures personnel evacuation. Therefore, the fire door plays an important role in the occurrence of a fire, and is widely applied to many fields such as residential buildings, ships, buildings, chemical engineering, mechanical engineering, and the like. At present, all common fireproof doors are metal doors, and metal is not easy to burn and melt in a fire disaster by utilizing the characteristic of high melting point of metal, so that the metal can effectively prevent the fire disaster from spreading. However, although metal doors are not easily burned, metal has good thermal conductivity, high temperature conducted through metal doors can also ignite surrounding objects after a certain period of time, and the use of metal doors alone cannot completely block fire, and the existing metal doors are single in function and poor in fireproof performance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome not enough among the prior art, aim at provides a fire prevention access door based on 304 stainless steel, when the conflagration breaing out, utilizes the fire retardant liquid of storage in the lintel to flow into to the door frame in, can play certain stretching that prevents the intensity of a fire, ensures personnel sparse.

The utility model discloses a following technical scheme realizes:

a fireproof channel door based on 304 stainless steel comprises a door frame and a door leaf, wherein a door head is arranged at the top of the door frame, two leakage holes communicated with the door frame are formed in the door head, a cavity is arranged in the door head and is communicated with the cavity, a partition plate is arranged in the cavity and is provided with a through hole, grooves are further formed in two sides of the inner wall of the cavity and are located below the partition plate, wax blocks are arranged in the grooves, guide rods are arranged in the wax blocks, two ends of each guide rod are respectively connected with the two wax blocks, a fixed plate and two movable plates are arranged on each guide rod and are respectively located on two sides of the fixed plate, the two movable plates can respectively move towards the two wax blocks, third elastic pieces are arranged between the movable plates and the wax blocks and sleeved on the guide rods, and first elastic pieces are arranged between the movable plates and the fixed plate, first elastic component also overlaps on the guide bar, still has the arc of elastic component between two fly leafs, and the top of arc is equipped with the second shutoff ball that matches with the through-hole, and when first elastic component and third elastic component were in natural state, the second shutoff ball can carry out the shutoff to the through-hole to the fly leaf can carry out the shutoff to letting out the leakage hole.

Aiming at the problem that when a fire disaster occurs in the fireproof door in the prior art, the metal is not easy to burn and melt in the fire disaster by utilizing the characteristic of high melting point of the metal, so that the fire disaster can be effectively prevented from spreading. However, although metal doors are not easily burned, metal has good properties

The thermal conductivity, the high temperature conducted through the metal door can also ignite the surrounding articles after accumulating for a period of time, and the fire can not be completely blocked only by using the metal door, therefore, the technical scheme is that a cavity is arranged in the lintel, water is stored above the partition plate of the cavity, when the fire door is not heated in an initial state, the arranged wax block is in a solid state, the arranged first elastic part and the arranged third elastic part are in a balanced state, namely the elastic force generated by the third elastic part forces the movable plates to be positioned above the leakage holes to block the leakage holes, the first elastic part is in a compressed state, the arc plates arranged on the two movable plates are in a large bending state, and the second blocking balls on the arc plates can block the through holes on the partition plate, so that the water stored in the lintel cavity can not be leaked; when the conflagration breaing out, prevent the temperature rise of fire door, and with in heat conduction to the lintel, when the temperature in the lintel reaches the melting point of wax stone, the wax stone begins to melt, the elasticity that leads to the third elastic component reduces, under the effect of first elastic component, force two fly leafs on the guide bar and move towards both sides, and then make crooked arc board stretched gradually, finally make originally to the second shutoff ball of through-hole shutoff move down, open the through-hole, and simultaneously, the fly leaf is when removing, also will let out the leakage hole and open, the water of storage on the baffle spills over through-hole and let out the leakage hole, be used in preventing on the fire door, reach the fire-retardant effect of preventing fire door, ensure personnel are sparse.
