Description

Technical Field

[0001] The utility model belongs to the field of civil air defense safety, and particularly relates to a translation support for a high-tightness rubber-sealed safety protection door. Background Art

[0002] The civil air defense safety door is a special type specially designed and manufactured for civil air defense projects, and is used to ensure the safety of personnel's lives, material reserves, and the protection of important facilities in case of emergencies. During the use of the civil air defense safety door, it usually adopts an electric drive or manual operation method, and the door leaf rotates through a mechanical structure to open or close the civil air defense project.

[0003] However, for the horizontally rotating civil air defense safety door, the rotation amplitude of the side of the door body close to the rotating shaft is small, and the rotation amplitude of the side far from the rotating shaft is large. Therefore, the sealing effect of the sealing strip on the side far from the rotating shaft is good, while the sealing effect of the sealing strip on the side close to the rotating shaft is poor, which will bring potential safety hazards to civil air defense safety.

[0004] Therefore, a device is needed to ensure that the gap between the door body and the door frame is balanced after the door body rotates, the compression amount of the sealing strip is consistent, and sufficient sealing effect between the door body and the door frame is ensured. Summary of the Invention

[0005] The utility model solves the defect that the gap between the door body and the door frame in the prior art is unbalanced and easily affects the sealing effect between the door body and the door frame, and provides a translation support for a high-tightness rubber-sealed safety protection door. By making a connection between the door body and the rotating shaft, the door body can not only rotate around the rotating shaft, but also translate relative to the door frame, so that the gap between the door body and the door frame is balanced, the compression amount of the sealing strip is consistent, and sufficient sealing effect between the door body and the door frame is ensured.

[0006] The specific technical solution of the utility model is as follows: A translation support for a high-tightness rubber-sealed safety protection door includes a fixed support fixedly connected to the door frame and a rotating support fixedly connected to the door body. Both the fixed support and the rotating support are rotatably connected to the rotating shaft; the rotating support includes an inclined angle-adjusting rotating support and a supporting rotating support. An aligning roller bearing matched with the rotating shaft is arranged in the inclined angle-adjusting rotating support. A connecting plate waist-shaped hole for the door body to translate is arranged on the inclined angle-adjusting rotating support. A load-bearing arm waist-shaped hole matched with the rotating shaft and for the door body to translate is arranged on the supporting rotating support. The center distances between the centers of the two waist-shaped holes are equal.

[0007] The fixed support is fixed to the door frame, and the rotating support is connected to the door body. The fixed support and the rotating support are connected by a rotating shaft. The rotating support drives the door body to rotate relative to the rotating shaft, thereby realizing the closing and opening of the door body; the inclined angle-adjustable rotating support adjusts the inclined angle of the door body relative to the rotating shaft through a spherical roller bearing, so that the door body is parallel to the rotating shaft, and further makes the door body parallel to the door frame. The waist-shaped holes of the connecting plate on the inclined angle-adjustable rotating support and the load-bearing arm waist-shaped holes on the supporting rotating support enable the door body to translate. This translation occurs after the door body rotates relative to the door frame, reducing and equalizing the gap between the door body and the door frame. In this way, the sealing strip between the door body and the door frame is compressed, and the compression amount is consistent, so that there is sufficient sealing effect between the door body and the door frame.

[0008] Preferably, the fixed support includes a fixing plate and a connecting platform fixed on the fixing plate. The connecting platform is provided with a through hole for cooperating with the rotating shaft, and the upper surface of the connecting platform is provided with fixing holes distributed around the center of the through hole. The through hole on the connecting platform of the fixed support ensures that the rotating shaft remains vertically upright, and the rotating shaft will not tilt during the rotation of the door body.

[0009] Preferably, the inclined angle-adjustable rotating support includes a connecting plate and a connecting seat that can move relative to the connecting plate. The connecting plate is provided with a bearing mounting hole for cooperating with the spherical roller bearing, the upper surface of the connecting plate is provided with a bearing cover plate, and the side of the connecting plate is provided with the above-mentioned waist-shaped hole of the connecting plate. The connecting seat includes two parallel ear plates. The side where the waist-shaped hole of the connecting plate is located is inserted between the two ear plates. The ear plates are provided with pin holes, and the pin holes are coaxial with the waist-shaped hole of the connecting plate and are inserted with pins to connect the connecting plate and the connecting seat. The spherical roller bearing cooperates with the rotating shaft. Through the spherical bearing, the angle between the rotating shaft and the door body can be adapted and adjusted, so that the door body is parallel to the rotating shaft. The connecting plate and the connecting seat are inserted and matched, so that the connecting seat can rotate around the pin, and the pin can slide in the waist-shaped hole of the connecting plate, thereby realizing the translation of the door body.

[0010] Preferably, the connecting plate is provided with a locking hole, and the locking hole is on the same axis as the long axis of the waist-shaped hole. The connecting seat is provided with a pin hole, and the distance between the pin hole and the pin hole is equal to the distance between the locking hole on the connecting plate and the waist-shaped hole of the connecting plate. The waist-shaped hole of the connecting plate cooperates with the locking hole. After the door body translates, the pin hole and the locking hole remain coaxial, and the locking pin in the pin hole automatically falls into the locking hole to complete the translation locking, avoiding an increase in the gap between the door body and the door frame again under the action of external force.

[0011] Preferably, the supporting rotating bearing seat includes a load-bearing arm, a ball base plate arranged under the load-bearing arm, and balls are arranged between the load-bearing arm and the ball base plate; a ball slideway is arranged at the lower part of the load-bearing arm, a ball slideway is arranged on the upper surface of the ball base plate, and the balls are located between the upper and lower ball slideways; a load-bearing arm waist circular hole matched with the rotating shaft is arranged on the load-bearing arm, and the long axis direction of the load-bearing arm waist circular hole is the same as the length direction of the ball slideway. The load-bearing arm and the rotating shaft are matched through the load-bearing arm waist circular hole, so that the load-bearing arm can drive the door body to translate. Balls are arranged between the load-bearing arm and the ball base plate. When the load-bearing arm translates, the balls roll in the ball slideway, making the translation smoother.

[0012] Preferably, the load-bearing arm includes a load-bearing box matched with the rotating shaft and a connecting arm extending from the load-bearing box. A ball slideway plate is arranged at the lower part of the load-bearing box, and the ball slideway is arranged on the lower surface of the ball slideway plate.

[0013] Preferably, a ball baffle is arranged at the lower part of the load-bearing box. The ball baffle is perpendicular to the length direction of the ball slideway, and the height of the ball baffle is greater than the thickness of the ball slideway plate.

[0014] Preferably, one protective door is matched with four fixed bearing seats and four rotating bearing seats. One fixed bearing seat corresponds to one rotating bearing seat. The four rotating bearing seats include two inclined angle-adjusting rotating bearing seats and two supporting rotating bearing seats. According to the arrangement order from top to bottom, they are: one inclined angle-adjusting rotating bearing seat, one supporting rotating bearing seat, one inclined angle-adjusting rotating bearing seat, and one supporting rotating bearing seat.

[0015] The beneficial effects of the present utility model are as follows: The fixed bearing seat is fixed to the door frame, the rotating bearing seat is connected to the door body, the fixed bearing seat and the rotating bearing seat are connected by a rotating shaft, and the rotating bearing seat drives the door body to rotate relative to the rotating shaft, thereby realizing the closing and opening of the door body; the inclined angle-adjusting rotating bearing seat adjusts the inclination angle of the door body relative to the rotating shaft through a spherical roller bearing, so that the door body is parallel to the rotating shaft, and further makes the door body parallel to the door frame. The connecting plate waist circular hole on the inclined angle-adjusting rotating bearing seat and the load-bearing arm waist circular hole on the supporting rotating bearing seat enable the door body to translate. This translation occurs after the door body rotates relative to the door frame, reducing and equalizing the gap between the door body and the door frame. In this way, the sealing strip between the door body and the door frame is compressed, and the compression amount is kept consistent, so that there is sufficient sealing effect between the door body and the door frame.
