Description

Aluminum alloy pedal flap door of fire engine

Technical Field

The utility model relates to a fire engine part, concretely relates to pedal door that turns over of fire engine aluminum alloy.

Background

In order to take the equipment conveniently, the fire engine is provided with a pedal turning door which is specially used for taking the equipment in the equipment box, and the pedal turning door can be opened from the vehicle body and is used for standing on the vehicle body to take and place the equipment. The pedal turnover door of the existing fire engine is of a steel structure, the structure is complex, the weight is large, the pedal turnover door is not convenient to open and close, and the processing cost is also high. The task is urgent in the fire-fighting emergency rescue process, the time is life, the steel pedal flap door which is inconvenient to open and close easily consumes the physical strength of fire fighters, and the emergency rescue process is delayed. In addition, the flap door is heavy and needs to be locked after being closed, and if the flap door is forgotten to be locked, the flap door is easy to be automatically opened in the running process of the fire engine, so that certain danger exists.

Disclosure of Invention

The utility model aims at providing a simple structure, light in weight is convenient for open and close, can not open automatically after closing, and the fire engine aluminum alloy that the security is good is pedal to turn over a door.

The technical solution of the utility model is that: the door comprises a flap main body, the flap main body is a plate-shaped hollow aluminum alloy section, two T grooves which are parallel to each other are formed in one side of the upper plate surface of the flap main body, two hinges which are spaced from each other are arranged in the flap main body along the extending direction of the T grooves, each hinge is respectively composed of a movable part and a fixed part which are hinged to each other, the movable part of each hinge is respectively installed on the flap main body through a plurality of bolts and a plurality of nuts installed in the T grooves, the fixed parts are respectively installed on a fire fighting truck body through a plurality of bolts, an air spring is respectively arranged between the movable part of each hinge and the fire fighting truck body, the tail end of each air spring shell is respectively hinged to the fire fighting truck body, the end part of a piston rod is respectively hinged to the position of the hinge movable part of the hinge, and the two positions of.

The technical effects of the utility model are that: the novel safety door has the advantages of simple structure, light weight, convenience in opening and closing, no automatic opening after closing and good safety. The safety door can be automatically positioned after being closed and opened, cannot be automatically closed and opened, and has good safety. The safety of the fire-fighting hose is guaranteed, the using effect is good, and the fire-fighting hose is beneficial to smooth fire-fighting work. The aluminum alloy section is used as the main body of the flap door, so that the flap door is light in weight, easy to produce, process and install and production time is saved.

Drawings

Fig. 1 is a perspective view of an embodiment of the present invention.

Detailed Description

As shown in figure 1, the fire fighting truck comprises a flap main body 1, the flap main body 1 is a plate-shaped hollow aluminum alloy section, two T-shaped grooves 11 which are parallel to each other are arranged on one side of the upper plate surface of the flap main body 1, two hinges 2 which are spaced from each other are arranged on the flap main body 1 along the extending direction of the T-shaped grooves 11, each hinge 2 is respectively composed of a movable part 21 and a fixed part 22 which are hinged with each other, the movable part 21 of each hinge 2 is respectively arranged on the flap main body 1 through a plurality of bolts 3 and a plurality of nuts arranged in the T-shaped grooves 11, the fixed part 22 is respectively arranged on the body of the fire fighting truck through a plurality of bolts 3, an air spring 4 is respectively arranged between the movable part 21 of each hinge 2 and the body of the fire fighting truck, the tail end of the shell, the end parts of the piston rods are respectively hinged with the positions of the hinge movable parts 21 deviating from the hinge shaft, so that the two positions of closing and opening of the flap door main body 1 are positioned.

When the turnover door main body 1 is opened, a plurality of anti-skid edges 12 are arranged on the upward plate surface.

The anti-slip ribs 12 are parallel to each other and to the extending direction of the T-groove 11.

A plurality of reinforcing ribs 13 for dividing the interior of the turnover door main body 1 into a plurality of cavities are arranged between the upper plate surface and the lower plate surface of the turnover door main body 1.

The extending direction of each rib 13 is parallel to the extending direction of the T-shaped groove 11.

The side surface of the side opposite to the side where the two T-shaped grooves 11 are arranged on the flap door main body 1 is provided with one T-shaped groove 11. The T-slot 11 can be used for mounting rubber edge banding with cushioning and protective action.

The working principle is as follows: the flap body 1 is in a vertical state when closed and cannot be opened by itself under the action of the gas spring 4. Artificially open the in-process gas spring 4 that turns over a main part 1 and at first can be compressed gradually, is opened gradually along with turning over a main part 1, can compress air spring 4 to extreme position, surpasss the extension of kick-backing gradually again behind the extreme position, when turning over a main part 1 and being the horizontality by opening completely, under 4 spring effects of air spring, turns over a main part 1 and can be in the horizontality all the time, can not close by oneself. When the door is closed, the turnover door body 1 can be closed by manually pulling the turnover door body 1 up against the acting force of the gas spring 4, and the turnover door body 1 cannot be opened by self. Because the weight of the flap main body 1 made of the aluminum alloy material is light, under the thrust of the air spring 4, the flap main body 1 does not need to be locked and can not be opened by itself after being closed, the safety is ensured, and the weight of a fire engine body can be reduced.
