[0002] The new type of grain depot sealed and insulated door is a door designed specifically for grain storage. Grain depot is the abbreviation of grain warehouse, which plays the main role of national grain reserve, local grain reserve and grain circulation. Its main task is to complete the grain circulation links such as grain acceptance, storage, transportation and delivery. Good air tightness of grain depot warehouse is also necessary for safe grain storage. Poor air tightness of warehouse will increase the difficulty of pest control; air tightness of warehouse will also affect the effect of fumigation and controlled atmosphere pest control; poor air tightness of warehouse will destroy the storage stability of grain pile. The door of the grain depot is an important part of the grain depot, so the door of the grain depot must have the function of sealing and insulation.

[0003] The existing sealed and insulated doors of grain warehouses generally adopt the method of gluing sealing strips on the door frame and door leaf to ensure the sealing of the door body gap. The sealing strip plays a key shielding and sealing task when the door leaf and the door frame are closed. However, in the actual operation process of closing the door leaf, contact impact between the door leaf and the sealing strip is inevitable. The existence of this impact force, although it may not be enough to show obvious negative effects in the short term, may accelerate the wear rate of the sealing strip in the long run, thereby adversely affecting the sealing performance of the door body.

[0004] Therefore, it is necessary to provide a new type of grain depot closed thermal insulation door to solve the above-mentioned technical problems. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] In the specific implementation process, Figures 1 to 5 As shown, the new type of closed thermal insulation door of the grain depot includes a door frame 1, a sliding groove 2 is opened on the door frame 1, and the inner wall of the sliding groove 2 is sequentially provided with an elastic member, a sliding block 4 and a sealing strip 5, a plurality of elastic members are provided and are arranged at equal intervals in the vertical direction, two ends of the sliding block 4 are respectively fitted with the inner wall of the sliding groove 2 of the door frame 1, two ends of the sealing strip 5 are respectively extended and fitted with the sliding groove 2 of the door frame 1, and the sealing strip 5 extends out of the sliding groove 2 away from the side of the sliding block 4, and a plurality of door hinges 6 are provided on the surface of the door frame 1, and the other end of the door hinge 6 is fastened with a door leaf 7 by a screw, and the outer surfaces of the two door leaves 7 are fitted with the sealing strip, and the adjacent ends of the two door leaves 7 are provided with sealing members;

[0023] The elastic member is a telescopic spring 3, the two ends of which are respectively fixedly connected to the inner wall of the sliding groove 2 of the door frame 1 and the outer wall of the sliding block 4. The door frame 1 is detachably connected with a fixing plate 8 at the top of the sliding groove 2. By providing a detachable fixing plate 8, when it is necessary to replace the sealing strip 5, the fixing plate 8 is disassembled, the sealing strip 5 is pulled out, and a force is applied to the sliding block 4 to move toward one side of the telescopic spring 3, and the sealing strip 5 is put in, and the sliding block 4 and the sealing strip 5 are continuously pushed by the telescopic spring 3;

[0024] The upper and lower ends of the sliding block 4 are respectively fixedly connected with roller brackets 9, and a sliding roller 10 is rotatably connected between the roller brackets 9, and the sliding roller 10 located at the top is in contact with the bottom of the fixed plate 8. Through the setting of the sliding roller 10, the sliding block 4 can reduce friction during movement through the rotation of the sliding roller 10, thereby increasing its service life;

[0025] The adjacent ends of the front sides of the two door leaves 7 are respectively fixedly connected with connecting handles 11;

[0026] The seal includes a connecting block 12 fixedly connected to one of the door leaves 7, a sealing strip 13 fixedly connected to one side of the connecting block 12, the sealing strip 13 extends to the outside of the other door leaf 7, the other door leaf 7 is fixedly connected to a covering block 14, and the covering block 14 is bent and connected to the sealing strip 13 and the connecting block 12 in sequence.

[0027] The working principle provided by the utility model is as follows: during the specific implementation of the utility model, when operating the new type of grain storage closed insulated door to close, the operator applies an outward pulling force to the door handle, so that the door leaf 7 is closed with the door hinge 6 as the rotation center. When the door leaf 7 gradually approaches the closed state, the covering block 14 on the door leaf 7 will first contact with the sealing strip 2 13 on the other door leaf 7, and gradually fit with the continued rotation of the door leaf 7. When the door frame 1 is completely in a parallel state, the covering block 14 applies sufficient extrusion force to the sealing strip 2 13, so that the sealing strip 2 13 is tightly embedded in the gap between the two door frames 1, so as to achieve a tight seal in the longitudinal direction. At the same time, when the door frame 1 is about to reach a fully closed and flush state, the edge of the door frame 1 will contact with the sealing strip 1 5 pre-arranged in the sliding groove 2 and apply an extrusion effect to it, and the two ends of the sealing strip 1 5 are in contact with the sliding groove 2 is tightly fitted, playing a role in guiding movement in the horizontal direction. As the door frame 1 squeezes the sealing strip 15, the sealing strip 15 will drive the sliding block 4 to move in the sliding groove 2. In this process, the sliding block 4 will further squeeze the telescopic spring 3 connected to the sliding groove 2, so that it accumulates elastic potential energy. When the door frame 1 is finally in a flush closed state, the telescopic spring 3 that has accumulated elastic potential energy will generate a continuous driving force on the sliding block 4 and the sealing strip 15 through its own restoring force, ensuring that the sealing strip 15 is tightly fitted to the door frame 1 to form a solid horizontal sealing barrier. In this way, the new type of closed and insulated door of the grain depot successfully achieves all-round sealing of the door gap through the precise cooperation of the door frame 1, the covering block 14, the sealing strip 15 and the sealing strip 2 13, thereby maximizing the insulation effect inside the grain depot and reducing energy loss. At the same time, it also effectively prevents the influence of the external environment on the quality of grain storage.
