Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and more specifically to a door and window sealing device. Background Technology

[0002] Existing sliding doors and windows typically use sealing blocks that are directly fixed to the aluminum profile, leaving gaps between the sealing blocks and the frame material. This can easily lead to air and water leaks, making it difficult to effectively solve the problems. Patent document CN216690902U discloses a frame for an anti-detachment door and window sealing strip, comprising a PE film, PU foam, a frame, a sealing magnetic strip, and double-sided adhesive strips. This anti-detachment sealing strip utilizes a magnetic attraction design, enhancing the adhesion strength of the double-sided adhesive strip through magnetic force. This further improves the smoothness of the double-sided adhesive strip's bonding, making installation easier and effectively solving the problems of sealing strips not adhering tightly to the glass and door / window frame, wrinkling, and detachment during installation and use, achieving a better anti-detachment sealing effect. However, the adjustment capability of the above solution is limited, and the sealing performance is difficult to guarantee; its structure needs further improvement. Summary of the Invention

[0003] The purpose of this utility model is to provide a stable, reliable, and high-performance door and window sealing device to overcome the shortcomings of existing technologies.

[0004] This utility model achieves the above-mentioned objective by adopting the following technical solution: a door and window sealing device, characterized in that it includes a shell, a telescopic block, and a spring that are connected to the profile frame material. The shell is provided with a telescopic block mounting cavity for accommodating the telescopic block. The telescopic block is movably disposed in the telescopic block mounting cavity. The spring connects the telescopic block and the shell. The telescopic block is provided with a groove, and a sealing strip is installed in the groove. In use, the telescopic block is pushed upward under the force of the spring, thereby pressing the sealing strip against the profile frame material, reducing gaps, and preventing rainwater from entering.

[0005] As a further explanation of the above solution, the bottom of the telescopic block is provided with a spring mounting groove. The spring is inserted into the spring mounting groove, and its end extends out of the groove opening and presses against the bottom of the telescopic block mounting cavity. By setting the spring, it can adapt to different gaps, so that the telescopic block can fit tightly against the profile frame material.

[0006] Furthermore, the outer shell and the telescopic block are L-shaped metal parts, and the sealing strips are distributed on the top and side of the vertical part of the metal parts and the top and side of the horizontal part.

[0007] Furthermore, the side of the outer casing is provided with a recess for corresponding engagement with the side plate of the profile frame.

[0008] Furthermore, the side panels of the profile frame are equipped with brushes, which rest against the side of the outer shell to prevent direct contact between the two from causing noise and wear.

[0009] Furthermore, the outer shell includes L-shaped left and right side panels, a bottom plate, a back plate, and a T-shaped end plate. The left and right side panels are respectively located on both sides of the bottom plate, the back plate is connected between the left and right side panels, and the T-shaped end plate stands at the end of the bottom plate. There are gaps between the two sides of the T-shaped end plate and the left and right side panels, respectively.

[0010] Furthermore, there is a beveled transition between the right side panel and the bottom panel, and a chamfered transition between the bottom panel and the back panel.

[0011] The beneficial effects that can be achieved by adopting the above-mentioned technical solution in this utility model are as follows.

[0012] This utility model adopts a door and window sealing structure mainly composed of an outer shell, a telescopic block, and a spring that are connected to the profile frame. The outer shell is provided with a telescopic block mounting cavity to accommodate the telescopic block. The telescopic block is movably disposed in the telescopic block mounting cavity, and the spring connects the telescopic block and the outer shell. The telescopic block is provided with a groove, and a sealing strip is installed in the groove. In use, the telescopic block is pushed upward under the force of the spring, thereby pressing the sealing strip against the profile frame, reducing gaps, preventing rainwater from entering, and maintaining a sealed state throughout the use process.

The profile frame 1 includes a left frame 1-1 and a right frame 1-2 arranged symmetrically. A connector 1-3 connects the left and right frame pieces, making them easy to assemble and disassemble. The left and right frame pieces are inverted L-shapes. A T-shaped plate 1-4 is horizontally arranged inside the profile frame, and the T-shaped plate 1-4 presses against the housing 2. The housing 2 has a telescopic block mounting cavity to accommodate the telescopic block 3. The telescopic block is movably disposed in the telescopic block mounting cavity. The spring 4 connects the telescopic block 3 and the housing 2. The telescopic block 3 has a groove 3-1, in which a sealing strip 5 is installed. In use, the telescopic block is pushed upward under the force of the spring, thereby pressing the sealing strip against the profile frame, reducing gaps and preventing rainwater from entering. The bottom of the telescopic block 3 is provided with a spring mounting groove 3-2. The spring 4 is inserted into the spring mounting groove 3-2 and its end extends out of the groove opening and presses against the bottom of the telescopic block mounting cavity.

The side of the outer shell is provided with a recess for corresponding cooperation with the side plate of the profile frame 1. The side plate of the profile frame 1 is provided with a brush 6, which abuts against the side of the outer shell to avoid direct contact between the two and generate noise and wear.

[0026] Furthermore, the outer casing 2 includes L-shaped left and right side panels 2-1 and 2-2, a bottom plate 2-3, a back plate 2-4, and a T-shaped end plate 2-5. The left and right side panels are respectively located on both sides of the bottom plate, and the back plate connects between the left and right side panels. The T-shaped end plate stands at the end of the bottom plate, with gaps between the two sides of the T-shaped end plate and the left and right side panels, respectively. The right side panel is connected to the bottom plate by a beveled edge 2-6 for transition, and the bottom plate and back plate have a chamfered transition, which is not only aesthetically pleasing but also prevents users from being cut during installation.

[0027] Compared with the prior art, this utility model adopts a method in which the telescopic block is movably set inside the outer shell and connected between the telescopic block and the outer shell by a spring; the telescopic block is provided with a groove, and a sealing strip is installed in the groove; when in use, the telescopic block is pushed upward under the force of the spring, so that the sealing strip presses against the profile frame material, reducing gaps and preventing rainwater from entering, thus achieving a sealed state throughout the use process.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
