Detailed Description
The present utility model will be further described with reference to the accompanying drawings and specific embodiments so as to more clearly understand the technical ideas claimed in the present utility model.
The double-leaf protective airtight door with strong impact resistance as shown in fig. 1-3 comprises a threshold 1, two airtight doors 2 are arranged on the inner side of the threshold 1 in a flat-open mode, buffer steel plates 3 are arranged on the outer surfaces of door plates on two sides of the airtight doors 2 in a covering mode, grid ribs 4 which are in contact with the door plate surfaces of the airtight doors 2 in a propping mode are distributed on the back face of the buffer steel plates 3, buffer springs 6 are arranged in a cavity 5 formed between the grid ribs 4, two ends of each buffer spring 6 are connected with the airtight doors 2 and the buffer steel plates 3 respectively, and the buffer steel plates 3 are fixedly connected onto the door plate surfaces of the airtight doors 2 from the front face through countersunk head bolts at four corners of each buffer steel plate.
The top of the buffer steel plate 3 is provided with notches 7 at two sides of the airtight door 2, the bottom of the buffer steel plate 3 is provided with notches 7 at two sides of the airtight door 2, the notches 7 are led to a cavity 5 at the back of the buffer steel plate 3, locking bolts 8 are arranged in the cavity 5 corresponding to the notches 7, inserting holes 9 are arranged in the buffer steel plate 3 and the doorsill 1 corresponding to the locking bolts 8, a first clamping groove 10 and a second clamping groove 11 are arranged on the outer wall of one side of the notches 7, and a positioning rod 12 which can be clamped in the first clamping groove 10 or the second clamping groove 11 is arranged at one side of the lower part of the locking bolts 8. Reinforcing ribs 13 can be additionally arranged between the first clamping groove 10 and the second clamping groove 11 to strengthen connection so as to improve the fastening structure strength of the positioning rod 12.
When the airtight door 2 is opened, the positioning rod 12 of the locking bolt 8 is clamped in the second clamping groove 11, and the locking bolt 8 is separated from the jack 9 on the threshold 1 and is retracted into the jack 9 of the buffer steel plate 3; after the airtight door 2 is closed, the positioning rod 12 is shifted to be separated from the second clamping groove 11, the locking bolt 8 is pushed upwards to be inserted into the jack 9 on the doorsill 1, and the positioning rod 12 is clamped in the first clamping groove 10 to position the locking bolt 8, so that the connection between the airtight door 2 and the doorsill 1 is enhanced, and the anti-collision capability is enhanced; the outer surface of the door plate of the airtight door 2 is provided with the buffer steel plate 3, the grid ribs 4 are in contact with the door plate surface of the airtight door 2 while strengthening the structural strength of the buffer steel plate 3, when the airtight door is impacted by strong force, the strong force can be dispersed to the airtight door 2 under the action of the buffer spring 6 and the grid ribs 4, the direct impact to the airtight door 2 is reduced and lightened, and when the buffer steel plate 3 and the doorsill 1 are locked and connected by the locking bolt 8, the airtight door 2 is kept firmly connected with the doorsill 1 when the airtight door is impacted by strong force, the buffer impact force can be further dispersed by using the support of the doorsill 1, and the impact resistance of the airtight door 2 is improved as a whole.
The positioning rod 12 of the locking bolt 8 and the first clamping groove 10 can be correspondingly provided with the fastening screw hole 14, after the locking bolt 8 is inserted into the jack 9 on the doorsill 1 and the positioning rod 12 is clamped in the first clamping groove 10, the positioning rod 12 is fixedly locked in the first clamping groove 10 by connecting the fastening screw hole 14 with the fastening screw hole 14, so that the positioning rod 12 is prevented from being separated from the first clamping groove 10 due to shaking of the airtight door 2 when strong impact is applied, the connection between the buffer steel plate 3 and the doorsill 1 is failed, and the integral stability of the impact strength is ensured.
In this embodiment, the two airtight doors 2 are hinged to the door sill 1, and the impact-resistant structure formed by the buffer steel plate 3, the buffer spring 6 and the locking bolt 8 can be applied to the two protective airtight doors that are pushed and pulled by pulleys. The buffer steel plate 3 can also be fixed on the door panel surface of the airtight door 2 by adopting a welding mode. Alternatively, as shown in fig. 4, a side wall edge 30 fixedly connected to the airtight door 2 is formed on the side wall extending from the outer periphery of the buffer steel plate 3 to the airtight door 2, and the side wall edge 30 is fixed to the airtight door 2 by a countersunk bolt on the side wall of the airtight door 2, so that the fastening manner does not see the bolt for fastening and fixing the buffer steel plate 3 after the airtight door 2 is closed, the simplicity and the integrity are further improved, and the bonding strength of the buffer steel plate 3 and the airtight door 2 is also higher.
Various other corresponding changes and modifications will occur to those skilled in the art from the foregoing description and the accompanying drawings, and all such changes and modifications are intended to be included within the scope of the present utility model as defined in the appended claims.
