Description
Technical Field
[0001] The utility model relates to the technical field of doors and windows, and particularly relates to a buffering device for doors and windows. Background Art
[0002] Doors and windows, as key components of buildings, not only divide indoor and outdoor spaces but also perform multiple functions such as heat preservation, sound insulation, and anti-theft. The realization of these functions places extremely high requirements on the materials, processes, and designs of doors and windows. However, in actual use, due to factors such as inertia and gravity, the closing of doors and windows often generates a large impact force, which not only damages the doors and windows themselves but also affects their sealing performance and service life.
[0003] Specifically, when doors and windows are closed quickly, due to their own weight and inertia, they often generate a strong impact when contacting the door frame. This impact may not only cause deformation and damage to the doors and windows but also affect their sealing performance, greatly reducing the effects of heat preservation, sound insulation, etc. At the same time, the long-term impact force will accelerate the aging of the doors and windows, shorten their service life, increase the frequency of maintenance and replacement, and thus increase the use cost.
[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a buffering device for doors and windows. Content of the Utility Model
[0005] The purpose of the utility model is to provide a buffering device for doors and windows to solve the problems raised in the above background art.

[0008] As a preferred technical solution, positioning seats are arranged on both sides of the spring, arc-shaped openings are arranged on the opposite inner walls of the two positioning seats, and the arc-shaped openings are matched with the spring.
[0009] As a preferred technical solution, the clamping columns are slidably matched with the bayonets, and a clamping portion is arranged at the edge of the clamping columns, and the clamping portion is abutted against the bayonets.
[0010] As a preferred technical solution, a convex column is arranged on the base.
[0011] As a preferred technical solution, the convex posts, positioning seats, and clamping posts are integrally processed with the base.

[0018] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.
[0019] Such as Figure 1 、 Figure 2As shown in the figure, the present utility model provides a technical solution for a buffer device used for doors and windows: It includes a base 1, on which a convex column 12 is provided. A slow-down cover 4 is provided on the base 1. Symmetrically penetrating openings 41 are provided on the slow-down cover 4. On the base 1, clamping columns 5 are symmetrically provided. The clamping columns 5 are matched with the openings 41, and the clamping columns 5 are in sliding fit with the openings 41. And a clamping portion 51 is provided at the edge of the clamping column 5, and the clamping portion 51 abuts against the opening 41. A spring groove 11 is provided on the base 1, and a spring 3 is installed in the spring groove 11. Positioning seats 2 are provided on both sides of the spring 3. Arc-shaped openings 21 are provided on the opposite inner walls of the two positioning seats 2. The arc-shaped openings 21 are matched with the spring 3. And both ends of the spring 3 respectively abut against the slow-down cover 4 and the base 1. The convex column 12, the positioning seat 2 and the clamping column 5 are integrally processed with the base 1.
[0020] According to the above solution, in this embodiment, during use, when the doors and windows are closed, the slow-down cover 4 first contacts the doors and windows and receives the impact force of the doors and windows. Under the action of the impact force, the slow-down cover 4 slides along the clamping column 5 and simultaneously compresses the spring 3. The elastic force of the spring 3 enables the slow-down cover 4 to produce a certain buffering effect when receiving the impact force, reducing the impact force when the doors and windows are closed. When the slow-down cover 4 slides to the edge of the clamping column 5, the clamping portion 51 abuts against the opening 41, preventing the slow-down cover 4 from continuing to slide. At this time, the elastic force of the spring 3 reaches the maximum value, forming the maximum buffering effect. Then, under the action of the elastic force of the spring 3, the slow-down cover 4 slowly resets and waits for the next buffering action. The convex column 12 on the base 1 plays a guiding role, so that the screen window grid will not swing back and forth under external force and reduce noise. The arc-shaped opening 21 on the positioning seat 2 is matched with the spring 3, enabling the spring 3 to slide smoothly along the arc-shaped opening 21 when being compressed, reducing the friction force and improving the buffering effect. At the same time, the design of the arc-shaped opening 21 can also prevent the spring 3 from detaching from the positioning seat 2 when receiving an excessive impact force, improving the reliability of the device.
[0021] The buffer device for doors and windows of the present utility model realizes the buffering effect when the doors and windows are closed by setting components such as the slow-down cover 4, the base 1, and the spring 3, effectively solves the impact force problem existing in the use of doors and windows, and improves the service life and sealing performance of the doors and windows. At the same time, the buffer device has a simple structure, is easy to install, is applicable to various types of doors and windows, and has a wide application prospect. In addition, the buffer device also has advantages such as shock absorption and noise reduction, improving the comfort and quietness of using doors and windows.
