Abstract
A non-pressure air door capable of quickly replacing an air blocking pad comprises a non-pressure air door main body, wherein air blocking plates arranged oppositely are arranged on the side edges of the air door, namely the side edges of the connected sides of two air doors, and the air blocking plates integrally extend outwards from the edge of a door body and are thinner; the wind shielding cushion pressing plate is positioned on the surface of the air door and corresponds to the position of the wind shielding plate, and is a long plate body which is hinged on the surface of the air door; the utility model discloses simple structure, convenient to use can high efficiency's installation, changes the pad that keeps out the wind. And through the setting of deep bead, appear deformation in the air door, when two air door butt joint positions can not be to tight, the cooperation leather packing plays the effect of preventing the hourglass wind.
Description
Technical Field
The utility model relates to a mine ventilation field especially relates to a can quick replacement keep out wind non-pressure air door of pad.
Background
The problem that the air pressure is large and an underground air door is not easy to open exists in a connecting roadway between main air inlet and return roadways of a mine. In order to facilitate the passing of personnel, the existing method for solving the corresponding problems usually adopts a split type non-pressure air door, and the air door is convenient to open by matching with a connecting rod balance structure. The research and improvement of the prior art on the corresponding problems are mainly focused on the connecting rod balance structure of the non-pressure air door. However, when the damper is closed, the wind shielding pad on the side frame of the damper, also called wind shielding leather, plays a role in preventing wind leakage, besides the damper. The existing wind shielding pad is complex in installation form, easy to age and wear and easy to cause wind leakage, and can be replaced timely and quickly. In addition, the traditional split type air door is deformed due to the fact that the service life is prolonged, and air leakage can occur.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art weak point, provide a simple structure, safe and reliable can the quick replacement keep out the wind non-pressure air door of pad.
The equipment comprises a non-pressure air door main body, wherein the non-pressure air door main body can refer to a non-pressure air door in the prior art, and the specific structure of the non-pressure air door main body is not described in detail herein. The wind shields which are arranged oppositely are arranged on the side edges of the air doors, namely the side edges of the connected sides of the two air doors. The wind shield extends outwards from the edge of the door body integrally and is thin. And under the closed state of the two air doors, the wind shields on the two air doors are respectively attached to the outer surfaces of the opposite air doors.
And a wind shielding cushion pressing plate is arranged on the surface of the air door and corresponds to the position of the wind shielding plate. The wind shielding cushion pressing plate is a long plate body and is hinged to the surface of the air door. Which when closed can conform to the outer surface of the windscreen.
Be located the wind screen and fill up the clamp plate and go up the array and be equipped with the spacing nail, be located the deep bead surface and be equipped with the recess that corresponds with the spacing nail.
Furthermore, the limit pin and the groove on the surface of the wind screen plate are in a magnetic adsorption mode, so that when the stop wind cushion pressing plate is closed with the wind screen plate, the wind cushion pressing plate is opened.
Furthermore, the upper portion that is located the pad clamp plate keeps out the wind articulates and is provided with spacing jack catch, spacing jack catch is L shape, when the pad clamp plate keeps out the wind closes with the deep bead, can further prevent to keep out the wind and fill up the clamp plate and open again through spacing jack catch.
The utility model discloses during the use, the pad that keeps out the wind that will cut passes through the mode that the banking pin pierces through, makes it be fixed in keep out the wind and fills up on the clamp plate, then folds and keep out the wind and fill up clamp plate and deep bead, and the recess on banking pin and the surface of the wind-break plate is the absorbent form of magnetic force, makes keep out the wind and fills up the clamp plate and the deep bead is in the state of foldeing, and further spacing fixed through spacing jack catch prevents to keep out the wind and fills up the.
The beneficial effects of the utility model are that, the utility model discloses simple structure, convenient to use can high efficiency's installation, changes the pad of keeping out the wind. And through the setting of deep bead, the deep bead is just also outwards extended by a body edge is integrative, under two air door closed condition, and the deep bead on two fans of doors is laminated respectively in the form that sets up of the surface of offside air door, appears deforming at the air door, and when two air door butt joint positions can not be to tight, the cooperation leather packing plays the effect of preventing the hourglass wind.

Detailed Description
Referring to fig. 1 and 2, a can quick replacement keep out non-pressure air door of wind pad include the non-pressure air door main part, the non-pressure air door main part that here said can refer to the non-pressure air door among the prior art, its specific structure here is no longer repeated. The wind shields 4 which are arranged oppositely are arranged on the side edges of the air doors, namely the side edges of the two connected air doors. The wind shield 4 integrally extends outwards from the edge of the door body, and is thin. And in the closed state of the two air doors, the wind shields 4 on the two air doors are respectively attached to the outer surfaces of the opposite air doors.
And a wind shielding cushion pressing plate 2 is arranged on the surface of the wind door and corresponds to the position of the wind shielding plate 4. The wind shielding cushion pressing plate 2 is a long plate body and is hinged to the surface of the air door. Which when closed can conform to the outer surface of the windscreen 4.
Be located the mat clamp plate 2 that keeps out the wind and go up the array and be equipped with spacing nail 3, be located 4 surfaces of deep bead and be equipped with the recess that corresponds with spacing nail 3.
Furthermore, the recess on the surface of stop pin 3 and deep bead 4 is the form of magnetic force absorption to when preventing backstop cushion clamp plate 2 and deep bead 4 from closing, cushion clamp plate 2 opens keeps out the wind.
Furthermore, the upper portion that is located the pad clamp plate 2 that keeps out the wind articulates and is provided with spacing jack catch 1, spacing jack catch 1 is L shape, when the pad clamp plate 2 that keeps out the wind closes with deep bead 4, can further prevent to keep out the wind through spacing jack catch 1 and fill up clamp plate 2 and open again.
The utility model discloses during the use, the pad that keeps out the wind that will cut passes through the mode that stop pin 3 pierces through, makes it be fixed in keep out the wind and fills up on the clamp plate 2, then folds and keep out the wind and fill up clamp plate 2 and deep bead 4, and the recess on stop pin 3 and deep bead 4 surface is the absorbent form of magnetic force, makes keep out the wind and fill up clamp plate 2 and deep bead 4 and be in the state of foldeing, through spacing jack catch 1 further spacing fixed, prevents to keep out the wind and fill up clamp plate 2 and reopen.
