Description

Technical Field

[0001] The utility model relates to the technical field of metal doors, in particular to a push-pull type metal door with an anti-collision structure. Background Art

[0002] A sliding door refers to a door that can be pushed and pulled. It is a common door in a household. The existing sliding door has a single structure. When the sliding door is closed, a large impact force will be generated. Therefore, an anti-collision structure needs to be set for buffering. For example, Chinese patent CN214091543U discloses a new anti-collision sliding door and window. The utility model has a simple structure and a novel design. A buffer mechanism is provided, which can greatly reduce the impact force on the inner frame when the door frame is closed, thereby avoiding the situation where the door frame and the inner frame are easily damaged in the case of long-term collision. A magnet and an iron sheet are also provided. The magnetic attraction between the two can improve the airtightness of the door frame when it is closed. The sealing gasket can further improve the airtightness. At the same time, it also has the effects of dustproof and sound insulation. Although the device can play an anti-collision effect, its buffer mechanism is mainly achieved through the elastic force of a spring or the like. Buffering can only be performed after a collision. If the pushing and pulling speed is fast, the buffering effect is not very good, and sometimes even rebounding may occur. For this reason, we propose a sliding metal door with an anti-collision structure. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In view of the shortcomings of the prior art, the utility model provides a sliding metal door with an anti-collision structure, which has the advantages of reducing the opening speed of the sliding door when pushed and pulled to the edge position, so that the sliding door opens slowly and has a good anti-collision effect, thereby solving the problems raised in the above background technology.

[0005] (II) Technical solution

[0006] The utility model provides the following technical solution: a sliding metal door with an anti-collision structure, comprising a sliding door, a lower door frame and an upper door frame, wherein the upper door frame and the lower door frame are parallel to each other, the top and the bottom of the sliding door are respectively movably connected to the inner parts of the upper door frame and the lower door frame, a slide is provided inside the lower door frame, a retarding ball is provided at the edge of the inner bottom wall of the slide, and anti-collision pads are provided on the inner walls on both sides of the slide.

[0007] Furthermore, a slider is provided at the bottom of the sliding door, and the slider is slidably connected to the inside of the slide. The bottom of the sliding door can slide inside the slide through the slider, so that the sliding door can be opened or closed by sliding.

[0008] Furthermore, an arc-shaped spring sheet is fixedly provided on one side of the anti-collision pad, and the side of the arc-shaped spring sheet away from the anti-collision pad is fixed to the inner wall of the slide. The anti-collision pad and the arc-shaped spring sheet are located on the inner walls on both sides of the slide. When the sliding door is opened to the edge position, the anti-collision metal frame will first contact the anti-collision pad, causing the anti-collision pad to move toward the side close to the inner wall of the slide, so that the arc-shaped spring sheet is compressed. Under the elastic force of the anti-collision pad and the arc-shaped spring sheet, the anti-collision buffering effect can be further improved.

[0009] Furthermore, an anti-collision metal frame is fixedly provided on the side surface of the sliding door, and tempered glass is provided inside the anti-collision metal frame. The anti-collision metal frame is used to protect the tempered glass inside, so that the tempered glass is not easily damaged during the sliding process.

[0010] Furthermore, a push-pull handle is provided on the front of the sliding door, and the push-pull handle facilitates the sliding door to be opened or closed.

[0011] Compared with the prior art, the utility model provides a sliding metal door with an anti-collision structure, which has the following beneficial effects:

[0012] 1. The sliding metal door with an anti-collision structure is provided with a slideway, and the bottom of the sliding door slides inside the slideway through a slider, so that the sliding door can be opened by pushing and pulling, and then a slow-moving ball is provided, and the surface of the slow-moving ball is a rough surface. When the sliding door moves to the edge of the slideway, the slider at the bottom moves on the surface of the slow-moving ball. At this time, the buffer ball rolls slowly, reducing the speed of the slider when it moves, so that the sliding door opens slowly, thereby achieving an anti-collision buffering effect.

[0013] 2. The sliding metal door with an anti-collision structure is provided with an anti-collision pad. The connection between the anti-collision pad and the inner wall of the slide is provided with an arc-shaped spring piece, which can further provide buffering when the sliding door moves to both sides, thereby further improving the buffering effect of the sliding door when it is opened.
