Description

Technical Field

[0001] This utility model relates to the field of shielding door design technology, and in particular to a shielding door with a damping and shock absorption device. Background Technology

[0002] Platform screen doors are widely used in modern urban rail transit, commercial buildings, and industrial plants. In urban rail transit, they separate the platform from the tracks, ensuring passenger safety and effectively reducing the impact of noise and airflow from train operation on the platform environment. In commercial buildings, they separate different areas, control temperature and humidity, and reduce energy consumption. In industrial plants, they block dust and harmful gases, maintaining a stable production environment. As these places increasingly demand higher levels of safety, comfort, and energy efficiency, the performance and quality of platform screen doors are becoming increasingly important.

[0003] Currently, traditional platform screen doors have several problems in practical use. Regarding shock absorption, most traditional platform screen doors lack effective shock absorption devices or have simple shock absorption structures. When the door closes, due to insufficient cushioning, the enormous impact force acts directly on the door body and related components. Over time, this can easily cause the door body to deform, and connecting parts to loosen and be damaged due to frequent stress. This not only shortens the lifespan of the platform screen door and increases replacement costs but may also pose safety hazards. In terms of fixing, the fixing methods of traditional platform screen doors after closing are unreliable. They usually rely on simple locking structures, and the door may accidentally open under external vibration or misoperation. This is because their fixing structure does not fully consider various complex situations and lacks sufficient stability and anti-accidental opening design. Furthermore, traditional platform screen doors are difficult to maintain. For example, when internal shock absorption components malfunction and need replacement, it often requires the removal of many other components, which is complex and consumes a lot of manpower and time. Therefore, the development of a platform screen door with good shock absorption, reliable fixing after closing, and easy maintenance is urgently needed. Utility Model Content

[0004] To address the problems of poor shock absorption in existing shielding doors leading to easy damage, unreliable fixation after closing resulting in accidental opening, and difficult and costly maintenance, this application provides a shielding door with a damping shock absorption device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A shielding door with a damping and shock absorption device includes a mounting frame. The right end of the front side of the mounting frame is connected to the shielding door body via a hinge. The top and bottom ends of the front side of the shielding door body are provided with horizontal sliding grooves. Limiting components are provided inside the horizontal sliding grooves at both ends. A connecting block is fixedly connected to the left end of the rear side of the mounting frame. The top and bottom ends of the right side of the connecting block are fixedly connected to the connecting rods. The right sides of the connecting rods at both ends are connected to the mounting plate via mounting components. Multiple spring dampers are installed on the front side of the mounting plate.

[0007] As a further improvement of this utility model, the limiting component includes a slider, which is slidably connected inside the transverse groove. A spring groove is provided on the front side of the slider, and telescopic connectors are slidably connected inside the spring grooves at both ends.

[0008] As a further improvement of this utility model, a spring is provided inside the spring groove, one end of the spring is connected to the rear side of the slider, and the other end is connected to the rear side of the telescopic connector.

[0009] As a further improvement of this utility model, a longitudinal sliding groove is provided at the left end of the front side of the mounting frame, and a limit sliding rod is slidably connected to the top and bottom ends of the longitudinal sliding groove.

[0010] As a further improvement of this utility model, the mounting assembly includes a fixing rod, and a damping shaft is fixedly connected to the top and bottom of the outer wall of the fixing rod. The left side of the damping shaft is fixedly connected to the right side of the connecting rod. A plurality of fixing rings are provided on the outer wall of the fixing rod, and the front side of the fixing rings is fixedly connected to the rear side of the mounting plate.

[0011] As a further improvement of this utility model, an installation notch is provided on the left side of the fixing ring.

[0012] As a further improvement of this utility model, a limit rod is rotatably connected to the right side of the damping shaft, and the left side of the limit rod abuts against the right side of the mounting plate.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. In this utility model, when the shielding door body is closed, it contacts the spring damper, which can effectively buffer the impact force, reduce damage to the shielding door body, thereby improving the overall service life and reducing replacement costs. After closing, through a simple operation, namely moving the limit slide rod and pulling and releasing the telescopic connector, the return force increases the friction between the telescopic connector and the limit slide rod, making it difficult for the telescopic connector to move. This operation is simple and requires no professional skills, which can further fix the shielding door, improve the stability and safety in the closed state, and prevent accidental opening.

[0015] 2. In this utility model, when the spring damper needs to be replaced, rotating the damping shaft drives the limiting rod to rotate, which releases the limiting on the mounting plate. Pulling the mounting plate causes the fixing rod to disengage from the fixing ring, allowing the mounting plate and spring damper to be replaced. The entire replacement process is simple, clear, convenient, and quick, without the need to remove a large number of other parts, saving maintenance time and labor costs, and ensuring that the shock absorption function of the shielding door is always in good condition.

[0028] Example 1:

[0029] refer to Figures 1-4 A shielding door with a damping and shock absorption device is characterized by comprising a mounting frame 1, a shielding door body 9 connected to the right front end of the mounting frame 1 via a hinge 10, a horizontal sliding groove 8 provided at the top and bottom front ends of the shielding door body 9, a slider 6 provided inside the horizontal sliding groove 8 at both ends, a connecting block 14 fixedly connected to the left rear end of the mounting frame 1, a connecting rod 15 fixedly connected to the top and bottom right sides of the connecting block 14, a mounting plate 5 connected to the right side of the connecting rod 15 at both ends via a fixing rod 12, a plurality of spring dampers 4 installed on the front side of the mounting plate 5, a slider 6 slidably connected inside the horizontal sliding groove 8, a spring groove provided on the front side of the slider 6, a telescopic connector 7 slidably connected inside the spring groove at both ends, a spring 17 provided inside the spring groove, one end of the spring 17 connected to the rear side of the slider 6, and the other end connected to the rear side of the telescopic connector 7, a longitudinal sliding groove 3 provided at the left front end of the mounting frame 1, a limit sliding rod 2 slidably connected to the top and bottom ends inside the longitudinal sliding groove 3.

[0030] Specifically, the operation of this type of shielded door with damping and shock absorption device is highly logical and practical. When the shielded door body 9 needs to be closed, the rear side of the shielded door body 9 will first contact the multiple spring dampers 4 on the front side of the mounting plate 5. The spring dampers 4 can effectively buffer the impact force generated when the shielded door closes, playing a shock absorption role. This greatly reduces the damage to the shielded door body 9 caused by frequent opening and closing, thereby improving the overall service life of the shielded door. After the shielded door body 9 is closed, in order to further fix the shielded door and make it more stable, subsequent operations are required. First, slide the two limiting slide rods 2 along the longitudinal sliding groove 3 to the middle position, and then pull the telescopic connector 7. At this time, the component 17 connected to it will also be stretched. Then, move the telescopic connector 7 to the outer wall of the two limiting slide rods 2, and then release the telescopic connector 7. At this point, 17 will use its own elasticity to drive the telescopic connector 7 to reset. However, since the limiting slide bar 2 is located behind the telescopic connector 7, it hinders the complete reset. Therefore, 17 will continue to apply force to the limiting slide bar 2 through the telescopic connector 7. This force increases the friction between the telescopic connector 7 and the limiting slide bar 2, effectively preventing the telescopic connector 7 from moving arbitrarily and ensuring the stability of the shielded door after it is closed.

[0031] Example 2:

[0032] refer to Figures 1-4 The top and bottom ends of the outer wall of the fixing rod 12 are fixedly connected to the damping shaft 13. The left side of the damping shaft 13 is fixedly connected to the right side of the connecting rod 15. The outer wall of the fixing rod 12 is provided with multiple fixing rings 11. The front side of the fixing ring 11 is fixedly connected to the rear side of the mounting plate 5. The left side of the fixing ring 11 is provided with an installation notch. The right side of the damping shaft 13 is rotatably connected to the limiting rod 16. The left side of the limiting rod 16 abuts against the right side of the mounting plate 5.

[0033] Specifically, during long-term use, the spring damper 4 may experience performance degradation or even damage due to wear or other reasons, requiring replacement. Replacement is performed by first rotating the damping shaft 13. This rotation causes the limiting rod 16 to rotate as well. When the limiting rod 16 rotates to a certain angle, it releases the restriction on the mounting plate 5. Next, pull the mounting plate 5. This movement causes the fixing ring 11 to move, disengaging the fixing rod 12 from the fixing ring 11. After completing these steps, the mounting plate 5 and the spring damper 4 mounted on it can be easily replaced, ensuring the damping and shock absorption function of the shielding door remains in good condition.

[0034] Working principle: When the shielding door body 9 is closed, the rear side of the shielding door body 9 will first contact the multiple spring dampers 4 on the front side of the mounting plate 5, thereby achieving the effect of shock absorption of the shielding door body 9 and improving the overall service life of the shielding door body 9. At the same time, after the shielding door body 9 is closed, the two limiting slide rods 2 are slid to the middle of the longitudinal sliding groove 3, and then the telescopic connector 7 is pulled, while 17 is extended. Then the telescopic connector 7 is moved to the outer wall of the two limiting slide rods 2, and then the telescopic connector 7 is released, so that 17 drives the telescopic connector 7 to reset. And because the limiting slide rods 2 are located on the rear side of the telescopic connector 7, the extension... If the telescopic connectors 7 and 17 cannot be fully reset, then 17 will continuously exert force on the limiting slide rod 2 through the telescopic connector 7, increasing the friction between the telescopic connector 7 and the limiting slide rod 2, and making the telescopic connector 7 difficult to move. At the same time, when the spring damper 4 has been used for a long time or is damaged and needs to be replaced, first rotate the damping shaft 13 to drive the limiting rod 16 to rotate, thereby releasing the limiting rod 16 from the limiting of the mounting plate 5. Then, pull the mounting plate 5 to drive the fixing ring 11 to move, so that the fixing rod 12 leaves the inside of the fixing ring 11, and then the mounting plate 5 and the spring damper 4 can be replaced.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
