Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and in particular relates to a buffer damping device for sliding doors and windows. Background Technology

[0002] Sliding doors and windows are a common door and window design, opening and closing via a sliding mechanism rather than the traditional rotating or sliding method. They are widely used in modern architecture, especially in spaces with limited space or requiring large openings. To reduce impact, noise, extend lifespan, and improve user experience, sliding doors and windows are equipped with appropriate damping devices.

[0003] Existing buffer damping devices are rubber strips attached to the sides of doors and windows. They utilize the elastic deformation of rubber to absorb impact energy and reduce collision noise. However, rubber strips are exposed to the air for a long time and are susceptible to environmental factors such as ultraviolet rays, rain, and dust, which can lead to aging, deformation, or detachment, reducing the buffering effect. Furthermore, the damping force of rubber strips is limited. When doors and windows slide at high speeds or when users exert great force, the deformation of rubber alone is insufficient to completely absorb impact energy, and significant collision noise will still be generated.

[0004] To address these issues, we provide a sliding door / window buffer damping device. Utility Model Content

[0005] The purpose of this utility model is to provide a sliding door and window buffer damping device, which solves the problems of existing buffer damping devices being easily damaged when exposed to air and having poor buffering effect through the cooperation of sealing mechanism and buffering mechanism.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a sliding door and window buffer damping device, comprising a frame, inside which a door and window body is installed; a sealing mechanism is provided on one side of the door and window body, the sealing mechanism comprising a horizontal plate provided on one side of the door and window body, a movable groove opened on one side of the horizontal plate, and an openable and closable sealing gasket fixedly connected to one side of the movable groove; a buffer mechanism is provided on one side of the horizontal plate, the buffer mechanism comprising a connecting rod fixedly connected to one side of the door and window body, a roller provided on one side of the connecting rod, and a buffer deceleration pad fixedly connected to one side of the frame.

[0008] The present invention is further configured such that the buffer mechanism includes a fixed cylinder disposed on one side of the connecting rod, a spring fixedly connected to one side inside the fixed cylinder, and a movable plate fixedly connected to one side of the spring.

[0012] The present invention is further configured such that a support wheel is fixedly connected to one side of the door / window body, and the support wheel is in contact with the horizontal plate.

[0013] The present invention is further configured such that the door / window body is in contact with the frame, and a handle is fixedly connected to one side of the door / window body.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, through the cooperation of the horizontal plate, movable groove, and openable / closable sealing gasket in the sealing mechanism, effectively isolates the buffer mechanism from external environmental corrosion, avoiding aging or damage caused by ultraviolet rays, rainwater, and dust, and significantly extending the service life of the device. Simultaneously, the sealing structure remains closed during door / window sliding, further improving sealing performance. The buffer mechanism achieves initial deceleration through the contact between the rollers and the buffer deceleration pad, combined with the elastic deformation of the spring and movable plate absorbing impact energy, forming the first level of buffering; the frictional cooperation between the rubber rod and the buffer pad further dissipates kinetic energy, forming the second level of buffering. This multi-level buffering design significantly reduces the impact force and noise when doors and windows close, improving user comfort.

[0016] 2. This utility model restricts the movement trajectory of the door and window body by using the limiting plate on the connecting rod and the support wheel together to prevent deviation or shaking; the spring and the movable plate provide elastic movement space for the roller to ensure smooth sliding, taking into account both stability and flexibility; after the rubber rod is inserted into the slot of the buffer pad, the door and window are self-locked and fixed in the open or closed state by friction, which enhances safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1 Please see Figures 1-5This utility model relates to a sliding door and window buffer damping device, comprising a frame 1, inside which a door and window body 2 is installed. The door and window body 2 is an important component of the building, possessing both functional and decorative properties, serving functions such as isolation, protection, ventilation, and lighting. This is existing mature technology and will not be elaborated upon here. A sealing mechanism 3 is provided on one side of the door and window body 2. The sealing mechanism 3 includes a horizontal plate 301 disposed on one side of the door and window body 2, which is fixedly connected to the frame 1. A movable groove 302 is formed on one side of the horizontal plate 301, and a door / window body is fixedly connected inside the movable groove 302. The side has an opening and closing sealing gasket 303; a buffer mechanism 4 is provided on one side of the horizontal plate 301. The buffer mechanism 4 includes a connecting rod 401 fixedly connected to one side of the door and window body 2. The connecting rod 401 and the opening and closing sealing gasket 303 can ensure that the movable groove 302 is always in a sealed state when the door and window body 2 slides. A roller 402 is provided on one side of the connecting rod 401, and a buffer deceleration pad 403 is fixedly connected to one side of the frame 1. The door and window body 2 opens and closes by relying on the roller 402. When the roller 402 rolls, the buffer deceleration pad 403 will reduce the speed of the roller 402. Specific Implementation Example 2 Please see Figures 1-5 Based on the first specific embodiment, the buffer mechanism 4 further includes a fixed cylinder 404 disposed on one side of the connecting rod 401, a spring 405 fixedly connected to one side inside the fixed cylinder 404, a movable plate 406 fixedly connected to one side of the spring 405, and a roller 402 extending through the fixed cylinder 404 and fixedly connected to the movable plate 406 at one end near the fixed cylinder 404. The design of the spring 405 and the movable plate 406 provides space for the roller 402 to move, ensuring normal rolling. The buffer mechanism 4 also includes a connecting frame 407 disposed on one side of the horizontal plate 301, fixedly connected to the fixed cylinder 404, a rubber insert 408 fixedly connected to one side of the connecting frame 407, and a buffer pad 409 disposed on one side of the rubber insert 408. A slot is provided on one side of the buffer pad 409, and buffering is achieved by the friction of the rubber insert 408 when inserted into the slot. When the rubber rod 408 is inserted into the slot, the door and window body 2 is fixed by friction. The connecting plate 410 is fixedly connected to one side of the buffer pad 409. The connecting plate 410 is fixedly connected to the frame 1. A slider is fixedly connected to one side of the movable plate 406. The slider is slidably connected to one side of the fixed cylinder 404. A groove matching the slider is opened on one side of the fixed cylinder 404. A limiting plate 5 is fixedly connected to one side of the connecting rod 401. The limiting plate 5 is fixedly connected to the fixed cylinder 404. The limiting plate 5 is in contact with the horizontal plate 301. A support wheel 6 is fixedly connected to one side of the door and window body 2. The support wheel 6 is in contact with the horizontal plate 301. The width of the limiting plate 5 and the support wheel 6 is greater than that of the horizontal plate 301 to ensure the limiting effect of the support wheel 6 and the limiting plate 5 on the door and window body 2. The door and window body 2 is in contact with the frame 1. A handle is fixedly connected to one side of the door and window body 2.

[0028] The operation process in this embodiment is as follows: When the door and window body 2 slides, the connecting rod 401 moves synchronously in the movable groove 302, and the opening and closing sealing gasket 303 always keeps the groove sealed to prevent external pollutants from entering the buffer mechanism 4 area. The roller 402 moves with the door and window body 2 and contacts the buffer deceleration pad 403 on the frame 1. The elastic deformation of the pad absorbs part of the kinetic energy and reduces the speed of the roller 402.

[0029] The movable plate 406 and spring 405 work together to provide space for the roller 402 to move, ensuring the roller 402 rolls normally. When the door / window body 2 is closed or opened, the connecting bracket 407 drives the rubber insert 408 to insert into the slot of the buffer pad 409, consuming the remaining kinetic energy through frictional resistance to achieve a smooth stop. If the door / window is fully closed or opened, the rubber insert 408 is engaged in the slot, fixing the door / window position through static friction. Through the synergistic effect of the sealing and buffering mechanism 4, the problems of easy aging and insufficient buffering of traditional rubber strips are solved, combining durability, quietness, and ease of operation, making it suitable for various sliding door / window scenarios.
