Technical Field

[0001] The utility model relates to the field of safety door protection equipment, in particular to a safety door protection device. Background Technique

[0002] The safety door, also known as the protective door, is a facility that provides opening and closing at specific occasions and times, playing a role in ensuring safety, isolation or controlling access. It is mainly applied to places and facilities such as buildings, transportation, warehouses, mines, banks, etc. to prevent illegal intrusion and safety accidents. With the acceleration of the urbanization process, the flow of people in public places such as shopping malls is increasing day by day. In places such as shopping malls, as an important facility for controlling access and isolating areas, the safety of the safety door is directly related to people's lives and property safety.

[0003] However, when the traditional safety door is closed, due to the structural design and power mechanism of its hinge, there is a risk of pinching nearby personnel or objects, especially the hands of children. Because of their small size and slower reaction than adults, they are more vulnerable to injury. For this reason, we have proposed a safety door protection device. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 , a safety door protection device, including a wall 1, a door frame 2 and a door 3. The door frame 2 is embedded in the wall 1, the door 3 is hinged on the door frame 2, a protective housing 4 is fixedly connected to one end of the side of the wall 1 close to the door 3, and a mounting clip seat 5 is fixedly connected to one end of the side of the door 3 close to the protective housing 4. It further includes:

[0027] A protection device 14, which is arranged inside the protective housing 4 and the mounting clip seat 5 and is used to prevent people or objects from being pinched at the hinge of the door.

[0028] Further, a convex block is fixed at one end of the mounting clip seat 5 away from the door 3 corresponding to the side close to the protective housing 4, and a mounting slot 15 is opened on the convex block.

[0029] Further, the protection device 14 includes an access slot 6, a leveling roller 10 and a gear 11. An access slot 6 is opened on one side of the protective housing 4 close to the mounting clip seat 5. The inner cavity of the protective housing 4 is a hollow structure. Two symmetrically arranged leveling rollers 10 are rotatably connected to the upper and lower inner walls of the access slot 6. Gears 11 are fixedly connected to both ends of the two leveling rollers 10, and the two gears 11 on the same side are meshed with each other.

[0030] Further, a clamping post 7 is movably inserted into the mounting slot 15. A protective metal sheet 8 is fixedly connected to the side of the clamping post 7. One end of the protective metal sheet 8 away from the mounting clip seat 5 extends into the inner cavity of the protective housing 4 through between the two leveling rollers 10.

[0031] Further, the protection device 14 further includes a rotating shaft 9 and a spring piece 12. The upper and lower inner walls of the protection housing 4 are fixedly connected with the rotating shaft 9. Three spring pieces 12 arranged at equal intervals are fixedly connected to the side surface of the rotating shaft 9. One end of the spring piece 12 is fixedly connected to the side surface of the rotating shaft 9, and the other end of the spring piece 12 is fixedly connected with a fixed clamping plate 13.

[0032] Further, the spring piece 12 is spirally wound around its side surface, and one end of the fixed clamping plate 13 away from the spring piece 12 is fixedly connected to one end of the protection metal sheet 8.

[0033] Further, one end of the protection metal sheet 8 away from the mounting clip seat 5 is wound and connected to the outer side of the ring corresponding to the spring piece 12 on the side surface of the rotating shaft 9.

[0034] Working principle: When the safety door starts to close, the included angle between the door 3 and the door frame 2 gradually decreases, and the mounting clip seat 5 moves along with the movement of the door 3. This action drives the movable clamping post 7 to slide in the mounting slot 15 through the convex block, thereby pulling the protection metal sheet 8 to move in the inner cavity of the protection housing 4. The moving path of the protection metal sheet 8 passes between the two flattening rollers 10. The two flattening rollers 10 are meshed with each other through the gears 11 at their two ends to form a stable transmission system. When the protection metal sheet 8 passes by, the flattening rollers 10 will ensure that the metal sheet remains flat, preventing it from deforming or warping due to gravity or external forces. This design ensures that the protection metal sheet 8 can always closely fit above the door frame 2 to form an effective protection barrier. At the same time, the spiral spring piece 12 plays a key regulating role during the movement of the protection metal sheet 8. One end of the spring piece 12 is fixed on the rotating shaft 9, and the other end is connected to the protection metal sheet 8 through the fixed clamping plate 13. When the protection metal sheet 8 moves, the spring piece 12 will generate a certain tension and buffering effect according to its spiral shape. This tension helps to ensure that the protection metal sheet 8 always maintains close contact with the flattening rollers 10, and the buffering effect can reduce the damage to the protection metal sheet 8 caused by the impact force generated when the door 3 closes. In addition, the spiral shape of the spring piece 12 also enables the protection metal sheet 8 to automatically adjust its position and direction during the movement. When the door 3 is closed to a certain extent, the protection metal sheet 8 will completely cover the included angle between the door 3 and the door frame 2 to form a completely enclosed protection barrier. When the door is closed, even if there are people or objects trying to be nearby, they will be effectively blocked by the protection metal sheet 8.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
