Description

Technical Field

[0001] This utility model relates to the field of roller shutter door manufacturing technology, and in particular to a buffer device for locking roller shutter doors. Background Technology

[0002] Roller shutters are a common security facility widely used in commercial shops, industrial plants, residential garages and other scenarios. The smoothness, security and user experience of their locking directly affect the daily use and property security of users. In the operation of roller shutters, the locking process is a key step to ensure their security function, and the cooperation between the lock and the docking parts is the core of the locking process. Traditional roller shutter door locking mechanisms have significant design flaws. The components that connect to the lock cylinder are often made of ordinary metal, lacking effective cushioning and having an inadequate design. This results in a direct, rigid collision between the lock cylinder and the connecting component when the roller shutter closes to lock. This collision generates considerable noise, severely disturbing the peace and quiet of nearby residents, especially at night or in quiet environments. Furthermore, prolonged rigid collisions cause wear and impact damage to the lock cylinder and connecting component, significantly shortening their lifespan. Damaged lock cylinders may prevent the roller shutter from locking properly, posing a significant safety hazard. Damaged connecting components require frequent repairs or replacements, increasing operating costs and maintenance workload. Therefore, these problems need to be addressed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figure 1-4 This utility model discloses a buffer device for locking a roller shutter door, comprising a buffer platform 1, with a fixing block 7 fixedly connected to the top of the buffer platform 1. The fixing block 7 facilitates the integration of components such as mounting blocks 12 and hinge seats 6, ensuring accurate relative positions between the components. Buffer components are installed at both ends of the top of the buffer platform 1. Two mounting blocks 12 are fixedly connected to the middle of the top surface of the fixing block 7, providing a stable sliding track for the sliding block and ensuring that the sliding block can only move horizontally along the mounting block 12, making the translation of the lock head docking ring 13 more stable and precise. Sliding blocks are slidably provided on both mounting blocks 12, and lock head docking rings 13 are fixedly connected to the top of the two sliding blocks. Two hinge seats 6 are symmetrically fixed to the fixing block 7, with linkage components on the hinge seats 6. The hinge seats 6 facilitate the flexible rotation of the telescopic rod 5 under force, ensuring accurate force transmission direction.

[0015] In this utility model, the buffer component includes hydraulic cylinders 2 installed at both ends of the top of the buffer platform 1. A mounting plate is fixedly connected to the hydraulic cylinder 2, and a buffer spring 3 is installed on the mounting plate. A fixed plate 4 is fixedly connected to the top of the buffer spring 3. A movable groove is provided at the bottom of the mounting plate. The buffer component facilitates effective absorption and reduction of impact force, working in synergy with the buffer spring 3 to enhance the buffering effect. A piston buffer rod 9 is provided inside the buffer spring 3. The top of the piston buffer rod 9 is fixedly connected to the bottom of the fixed plate 4, and the bottom of the piston buffer rod 9 is slidably connected to the hydraulic cylinder 2 through the movable groove. A sealing ring 11 is provided at the slidable connection between the piston buffer rod 9 and the hydraulic cylinder 2. The buffer spring 3 can absorb part of the impact force through its own elastic deformation, playing a preliminary buffering role. A mounting groove is provided on one side of the fixed plate 4, and a fixed shaft 10 is fixedly connected in the mounting groove. The fixed shaft 10 ensures that the telescopic rod 5 can rotate flexibly around it, allowing the telescopic rod 5 to freely adjust its angle during force transmission. The linkage component includes the telescopic rod 5 hinged to the fixed shaft 10. The bottom of the telescopic rod 5 is hinged to the hinge seat 6. A lifting plate is fixed to one side of the bottom of the telescopic rod 5. A sliding groove is opened in the lifting plate. Sliding plates 8 are hinged to both sides of the sliding block. The other end of the sliding plate 8 slides in the sliding groove. The sliding plate 8 facilitates the sliding block to slide on the mounting block 12, realizing the translation of the lock head docking ring 13, so that the lock head can be accurately docked. The lock head docking ring 13 is made of stainless steel. A neoprene rubber buffer layer is pasted on the inner side of the docking ring to prevent noise caused by rigid collision. The lock head docking ring 13 facilitates docking with the lock head of the roller shutter door, while preventing noise caused by rigid collision between the lock head and the docking ring.

[0016] Working Principle: When this utility model is used, firstly, when the roller shutter door falls and triggers the locking action, the lock head first contacts the lock head docking ring 13. The lock head docking ring 13 is made of stainless steel and can withstand the impact force of locking. Its inner neoprene rubber buffer layer can reduce the noise generated by rigid collision and initially buffer part of the impact force. Then, the impact force of the lock head is transmitted to the two sliding blocks at the bottom through the lock head docking ring 13. The sliding blocks slide along the mounting block 12, and at the same time drive the sliding plates 8 on both sides to slide in the sliding groove of the lifting plate at the bottom of the telescopic rod 5. The movement of the sliding plates 8 causes the telescopic rod 5 to rotate around the hinge seat 6, and the telescopic rod 5 will adaptively extend and retract, transmitting the impact force to the fixed plate 4. Then, after the fixed plate 4 is subjected to a downward force, it pushes the top buffer spring 3 to compress. The buffer spring 3 absorbs part of the impact force through elastic deformation, achieving initial buffering. At the same time, the fixed plate 4 drives the bottom piston buffer rod 9 to the hydraulic cylinder. The piston buffer rod 9 slides internally, and the sealing ring 11 at the sliding connection between the piston buffer rod 9 and the hydraulic cylinder 2 ensures that the hydraulic oil does not leak. The hydraulic oil in the hydraulic cylinder 2 generates throttling resistance due to the compression of the piston buffer rod 9, which further absorbs and reduces the impact force, forming a double buffer with the buffer spring 3, so that the locking impact force is effectively attenuated. Finally, during the entire buffering process, the buffer platform 1 provides stable support for the device, and the fixing block 7 integrates the mounting block 12, hinge seat 6 and other components into a whole, ensuring coordinated movement of each component. The fixing shaft 10 provides a rotation fulcrum for the telescopic rod 5, ensuring smooth force transmission and avoiding damage to components due to uneven force. After locking is completed, the elastic force of the buffer spring 3 will push the fixing plate 4 to reset, and the piston buffer rod 9 will reset synchronously under the action of the hydraulic oil in the hydraulic cylinder 2, driving the linkage component and the lock head docking ring 13 back to the initial position, preparing for the next locking. At this point, the use of the buffer device for locking the roller shutter door is completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
