Description

Technical Field

[0001] The present application relates to the technical field of sealed doors, and in particular to a two-way protective sealed door. Background Art

[0002] The patent with the published authorization announcement number CN219316822U discloses a two-way protective sealed door, which relates to the technical field of protective sealed doors, including a door leaf, a sealing strip arranged at the upper and lower ends of the door leaf, a door frame is provided on the door leaf, one side of the door leaf is hinged to the door frame, a wall is provided on the door frame, the sealing strip is used to block the gap between the door leaf and the door frame, and a fixing part for limiting its own rotation is provided on the door leaf. The patent sets a sealing strip to block the gap between the door frame and the door leaf, reduce the entry of poisonous gas along the gap, and improve the sealing of the protective sealed door.

[0003] The two-way protective sealed door in the above patent, when the door leaf is closed, will be affected by external force, causing the door leaf to be damaged or broken due to impact, which not only increases the cost of the door leaf and increases the loss, but also reduces the use effect of the door leaf.

[0004] For this purpose, the present application proposes a two-way protective closed door. Utility Model Content

[0005] The present application proposes a two-way protective closed door to solve the problems raised in the above-mentioned background technology; by setting a second buffer component, a buffer groove and a buffer rubber block, when the door leaf rotates to the inside of the door frame, the bottom of the moving block will contact the inside of the door frame, and the moving block will be extended to the inside of the installation groove by extrusion. When the moving block moves upward in the installation groove, it will drive the movable block to move synchronously, and the spring will be squeezed, so that the buffer rubber block extends to the outside of the door leaf and moves in the direction of the buffer groove. After the door leaf is completely closed, the buffer rubber block will move synchronously to the inside of the buffer groove. By setting the buffer rubber block into a triangular shape, it perfectly cooperates with the buffer groove. When the door leaf is closed, the buffer rubber block will be stuck in the buffer groove step by step, thereby slowly closing the door leaf. At the same time, when the door leaf is subjected to external force, it can play a certain buffering role and protect the door leaf to avoid direct collision between the door leaf and the door frame, thereby reducing the loss problem of the door leaf, reducing costs, improving the use effect and practicality, and greatly improving the practicality of the device.

[0034] Working principle: When the device is used, when closing the protective sealed door, first rotate the door leaf 3 towards the door frame 2. Through the setting of the side sealing assembly 4, the side sealing strip 42 is made of polyurethane sealing strip, which has good elasticity and wear resistance. It is favored for its high strength, wear resistance, waterproof and moisture-proof properties. The side sealing strip 42 will be stuck into the side sealing groove 41 set in the door leaf 3. Through the side sealing strips 42 on both sides, the gap between the door frame 2 and the door leaf 3 is sealed.

[0035] Through the setting of the first buffer component 5, a sponge block 52 is set in the side sealing strip 42. The sponge block 52 is made of rubber cotton. The main material is natural latex raw material foamed. It has rubber properties, good resilience, and will not deform. When the side sealing strip 42 is inserted into the side sealing groove 41, the shock absorbing effect of the side sealing strip 42 is increased, so that when the door leaf 3 is closed, a certain buffering effect is achieved.

[0036] By setting the bottom sealing assembly 6 and inserting the bottom sealing strip 62 into the bottom sealing groove 61, a sealing effect is achieved on the bottom of the door frame 2 and the door leaf 3, thereby increasing the sealing performance and improving the use effect.

[0037] When the door leaf 3 rotates to the inner side of the door frame 2, the bottom of the moving block 83 will contact the inner side of the door frame 2, and the moving block 83 will extend into the installation groove 7 by squeezing. By moving the moving block 83 upward in the installation groove 7, the movable block 82 will be driven to move synchronously, squeezing the spring 81, so that the buffer rubber block 92 extends to the outside of the door leaf 3 and moves in the direction of the buffer groove 91. After the door leaf 3 is completely closed, the buffer rubber block 92 will move synchronously into the buffer groove 91. By setting the buffer rubber block 92 into a triangular shape, it perfectly matches the buffer groove 91. When the door leaf 3 is closed, the buffer rubber block 92 will be stuck into the buffer groove 91 step by step, thereby slowly closing the door leaf 3. At the same time, when the door leaf 3 is subjected to external force, it can play a certain buffering role and protect the door leaf 3 to avoid direct collision between the door leaf 3 and the door frame 2, thereby reducing the loss problem of the door leaf 3, reducing costs, and improving the use effect and practicality.

[0038] By setting the limiting assembly 10, a limiting block 103 is set outside the movable block 82. When the movable block 82 moves, the limiting block 103 can slide synchronously outside the limiting rod 102, thereby limiting the movable block 82, thereby improving the movement effect.
