The space between the partition 16 and the outer panel 18 has polyurethane foam 19 and reinforcing mesh 20. This product is intended for use in residential buildings or enterprises.

[0004] The above-mentioned security doors are the most common type of security doors. During use, if the door leaf is turned forcefully to close the security door, the door leaf will collide with the door frame, making a loud noise and damaging the door leaf. Utility Model Content

[0005] This utility model provides a security door with a buffer structure, which can buffer the door leaf when closing, thereby reducing the noise when closing the door.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a security door with a buffer structure, characterized in that it includes a door frame and a door leaf rotatably connected to the door frame. The top and bottom surfaces of the door frame are provided with sliding grooves. Several sliding sleeves are provided in the sliding grooves and slide with each other. When the door is closed, the sliding sleeves are stacked in the sliding grooves. The smallest sliding sleeve has a sliding piece at one end fixedly connected to the door leaf. Several buffer pads are fixedly connected to the inner side wall of the sliding groove and each sliding sleeve. The end of the sliding piece away from the door leaf and the two outer side walls of each sliding sleeve are fixedly connected with a locking block that can abut against the buffer pad. When the door is closed, the locking block abuts against the corresponding buffer pad in sequence. The sliding groove, sliding sleeve and sliding piece are all arc-shaped.

[0007] A further preferred embodiment of this invention is that the buffer pad is elastic.

[0008] A further preferred embodiment of this invention is that the buffer pad is a triangular block or a hemispherical block.

[0009] A further preferred embodiment of this invention is: a slot is formed between two adjacent buffer pads to facilitate the insertion of the card block.

[0010] A further preferred technical solution of this utility model is as follows: each sliding groove and the inner wall of each sliding sleeve is fixedly connected with a limiting block that can abut against the locking block. When the door is opened, each limiting block abuts against its corresponding locking block.

[0011] A further preferred embodiment of this invention is that the length of the limiting block is greater than the depth between two adjacent buffer pads.

[0012] A further preferred embodiment of this invention is that the cushioning pad is made of rubber.

[0013] Compared with the prior art, this utility model includes a door frame and a door leaf. The top and bottom surfaces of the door frame are provided with sliding grooves, and several sliding sleeves are provided within the sliding grooves. A sliding piece is slidably connected within the smallest sliding sleeve. Several buffer pads are fixedly connected to the inner sidewalls of the sliding grooves and each sliding sleeve. A locking block is fixedly connected to the end of the sliding piece away from the door leaf and to the two outer sidewalls of each sliding sleeve. When the door is closed, the locking block abuts against the corresponding buffer pad in sequence. The sliding groove, sliding sleeve, and sliding piece are all arc-shaped. Therefore, when the door is closed, as the door leaf rotates, the locking block gradually engages between two corresponding buffer pads, and the locking of the buffer pads achieves the purpose of dissipating force, avoiding noise and damage to the door leaf caused by forceful slamming. This design reduces closing noise and protects the security door. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] Figures 1-6 As shown, a security door with a buffer structure includes a door frame 1 and a door leaf 2 rotatably connected to the door frame 1. The top and bottom surfaces of the door frame 1 are provided with sliding grooves 9. Several sliding sleeves 3 are provided in the sliding grooves 9 and slide with each other. When the door is closed, the sliding sleeves 3 are stacked in the sliding grooves 9. The smallest sliding sleeve 3 is slidably connected to a sliding piece 4, one end of which is fixedly connected to the door leaf 2. The sliding grooves 9, sliding sleeves 3 and sliding pieces 4 are all arc-shaped. Several buffer pads 5 are fixedly connected to the inner side wall of each sliding sleeve 3. The end of the sliding piece 4 away from the door leaf 2 and the two outer side walls of each sliding sleeve 3 are fixedly connected to a locking block 6 that can abut against the buffer pad 5. When the door is closed, the locking block 6 abuts against the corresponding buffer pad 5 in sequence.

[0020] Figures 1-6 As shown, when the door is closed forcefully, as the door leaf 2 rotates, the sliding plate 4 slides into the smallest sliding sleeve 3, and the two sliding sleeves 3 stack up in sequence. At this time, as the sliding plate 4 and the sliding sleeve 3 slide, the locking block 6 abuts against the buffer pad 5 in sequence. At the same time as the abutment, the door leaf 2 is stuck, thereby slowing down the rotation speed of the door leaf 2 and thus achieving the purpose of unloading force.

[0021] Figures 1-6 As shown, the design effectively slows down the rotation speed of the door leaf 2 through the cooperation of the locking block 6 and the buffer pad 5, thereby avoiding the loud noise that would damage the door leaf 2 when closing, effectively reducing the noise when closing, and protecting the door leaf 2.

[0022] Figures 1-6 As shown, a slot 7 is formed between two adjacent buffer pads 5 to facilitate the insertion of the locking block 6. When the locking block 6 is inserted into the slot 7 in sequence, the door leaf 2 will be stuck and the rotation speed will be reduced.

[0023] Figures 1-6 As shown, the buffer pad 5 is elastic and is a triangular or hemispherical block. The buffer pad 5 is made of rubber, which has good elasticity and resilience, making it easy for the locking block 6 to slide. Therefore, when the sliding plate 4 or the sliding sleeve 3 slides, as the locking block 6 slides, the locking block 6 squeezes the corresponding buffer pad 5, causing the buffer pad 5 to deform. In this process, the door leaf 2 is stuck. At the same time, the deformed buffer pad 5 can facilitate the locking block 6 to form abutment with the buffer pad 5, avoiding affecting the normal sliding of the locking block 6. This design allows the door to close smoothly and effectively slows down the closing speed during the closing process, thereby reducing the noise generated by closing the door.

[0024] Figures 1-6 As shown, each sliding groove 9 and the inner wall of each sliding sleeve 3 is fixedly connected with a limiting block 8 that can abut against the locking block 6. When the door is opened, each limiting block 8 abuts against its corresponding locking block 6. The length of the limiting block 8 is greater than the depth between two adjacent buffer pads. This design allows the locking block 6 to smoothly pass through the buffer pad 5 and be inserted into the slot 7, but it cannot pass through the limiting block 8.

[0025] Figures 1-6 As shown, the locking block 6 and the limiting block 8 work together to effectively prevent the separation of adjacent sliding sleeves 3, sliding sleeve 3 and sliding groove 9, and sliding sleeve 3 and sliding piece 4 when the door is opened, thus limiting the sliding range of sliding sleeve 3 and sliding piece 4.

[0026] Working principle: Figures 1-6 As shown, when the door is opened, as the door leaf 2 rotates, the slide plate 4 gradually slides out of the smallest slide sleeve 3, and during the sliding process, the locking block 6 is locked into the corresponding locking groove 7 one by one until the locking block 6 and the limiting block 8 in the smallest slide sleeve 3 form abutment. After that, the door leaf 2 continues to rotate, and the locking block 6 drives the smallest slide sleeve 3 to continue to slide until the door leaf 2 is fully opened. At this time, all the slide sleeves 3 are located outside the slide groove 9.

[0027] Figures 1-6As shown, when the door needs to be closed, the door leaf 2 is rotated. Due to the force, the slide plate 4 gradually slides into the smallest slide sleeve 3, and the locking block 6 separates from the limiting block 8 in the smallest slide sleeve 3. The sliding slide plate is further slid. At this time, the locking block 6 squeezes the corresponding buffer pad 5 to deform it until it is locked into the corresponding slot 7. At this time, the door leaf 2 is stuck. After that, the locking block 6 continues to slide until the slide plate 4 is completely slid into the slide sleeve 3. After that, the locking block 6 of the smallest slide sleeve 3 sequentially engages with the slot 7 in the next slide sleeve 3 and relieves the force on the door leaf 2 until all the slide sleeves 3 are stacked and all the slide sleeves 3 are located in the slide groove 9. At this time, the security door closes slowly.

[0028] The present invention provides a security door with a buffer structure. Specific examples have been used to illustrate the principle and implementation of the present invention. The descriptions of the embodiments are merely for the purpose of helping to understand the present invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
