Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a sliding door that can isolate dust, insulate sound and reduce noise. Background Technology

[0002] Aluminum alloy sliding doors and windows are widely used in various applications due to their advantages such as space saving and good lighting. However, in existing technology, when sliding doors and windows are closed, the door and window sashes are in hard contact with the frame, causing the sashes to bounce back and preventing them from fitting completely tightly together. This affects the dust and sound insulation performance of the doors and windows.

[0003] In the technical solution of the Chinese utility model patent with application number 202123146698.2 and title "A Shock-absorbing and Buffering Sliding Window", a first buffer strip and a first magnetic strip are vertically bonded to the inner side of the side beam of the window frame, and a second buffer strip and a second magnetic strip are bonded to one side of the window sash. The two buffer strips are used to buffer the impact force when the window is closed, and the attraction between the two magnetic strips is used to lock the window sash. At the same time, the two buffer strips are squeezed and tightly bonded together to achieve a sealing and sound insulation effect.

[0004] However, the following technical problems still exist in the use of this technology:

[0005] First, the magnetic strip and the buffer strip are arranged side by side. This means that the direction of the magnetic attraction between the magnetic strips is not in the same straight line as the direction of compression on the buffer strip. The magnetic attraction exerts a weaker compressive force on the buffer strip, resulting in less deformation of the two strips and poorer window sealing. Second, the buffer strip and magnetic strip need to be glued to the window frame and sash respectively. This not only makes installation inconvenient, but also makes the buffer strip and magnetic strip prone to falling off due to the aging of the adhesive after long-term use, resulting in a shorter service life.

[0006] Given the above-mentioned shortcomings of the existing technology, the applicant believes it is necessary to make technical improvements to provide a sliding door and window magnetic suction structure with better sealing and longer service life. Utility Model Content

[0007] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a magnetic suction structure for dustproof, soundproof and noise-reducing sliding doors and windows. The first magnetic strip is encased in a plastic shell, and the second magnetic strip is encased in a snap-on plastic shell to form the first and second magnetic strip bodies. In this way, the magnetic force direction between the two magnetic strip bodies is on the same straight line as the compression direction of the elastic buffer part, thereby generating a large compressive force on the elastic buffer part, resulting in a high degree of window sealing. Furthermore, during installation, the plastic shell, the first magnetic strip, the snap-on plastic shell, and the second magnetic strip can be installed simultaneously, making installation very convenient. The first and second magnetic strip bodies are also less likely to detach, providing users with a better user experience.

[0008] The technical solution of this utility model is implemented as follows: a magnetic structure for dustproof, soundproof, and noise-reducing sliding doors and windows, characterized by including a window frame vertical frame with an inner recess for mounting the window sash vertical frame, and a first magnetic strip mounting groove arranged along its height direction in the inner recess; a first magnetic strip body composed of a rubber shell and a first magnetic strip encased in the rubber shell; the first magnetic strip body is installed in the inner recess by the rubber shell and the first magnetic strip mounting groove being fitted together, and an elastic buffer portion is provided on the outer side of the rubber shell; a window sash vertical frame with an outer fastening groove; and a second magnetic strip body composed of a fastening plastic shell and a second magnetic strip encased in the fastening plastic shell, the second magnetic strip body being installed on the window sash vertical frame by the fastening plastic shell and the outer fastening groove being fastened together.

[0009] Furthermore, the two sides of the adhesive shell are respectively provided with mounting protrusions, and the two sides of the first magnetic strip mounting groove are respectively provided with mounting grooves for mounting the mounting protrusions.

[0010] Furthermore, the cross-sectional width d1 of the mounting protrusion is smaller than the cross-sectional width d2 of the mounting groove, so that the mounting protrusion can be movably mounted in the mounting groove; the bottom of the first magnetic strip mounting groove is also provided with a reset magnetic strip that is attracted to the first magnetic strip body.

[0011] Furthermore, the reset magnetic strip is composed of a third magnetic strip and a plastic covering shell covering the surface of the third magnetic strip. The plastic covering shell is provided with a buckle on both sides. The bottom of the first magnetic strip mounting groove is also provided with a mounting bottom groove. The reset magnetic strip is installed in the bottom of the first magnetic strip mounting groove by means of the buckle and the mounting bottom groove.

[0012] Furthermore, it also includes a plastic groove with an outer fastening groove. The vertical frame of the window sash is composed of a front assembly part, a rear assembly part, and a thermally broken plastic connecting strip connecting the front assembly part and the rear assembly part. The plastic groove is fastened into the fastening groove formed by the outer end faces of the front assembly part and the rear assembly part.

[0013] Furthermore, the plastic groove is provided with hooks on both sides, and the groove of the fastening groove is provided with corresponding fastening protrusions on both sides to fasten the hooks.

[0014] The beneficial effects of this utility model are:

[0015] First, the first and second magnetic strips are encased in a rubber shell and a snap-on plastic shell, respectively, and are then installed on the vertical frame of the window frame and the vertical frame of the window sash through the rubber shell and the snap-on plastic shell, respectively. When the window is closed, the magnetic attraction between the first and second magnetic strips is in the same straight line as the direction of compression of the elastic buffer, which allows it to produce greater elastic deformation. This ensures that the vertical frame of the window sash can be tightly fitted into the vertical frame of the window frame, forming a better dustproof, soundproof, and noise-reducing structure, and achieving better soundproof and dustproof effects. At the same time, the elastic buffer can also prevent the window sash from hitting the vertical frame of the window frame during the closing process, playing a role in shock absorption and impact prevention.

[0016] Secondly, when the first and second magnetic strips are respectively fastened to the window frame and sash, the installation of the first magnetic strip with the adhesive shell and the second magnetic strip with the fastening plastic shell can be achieved simultaneously, making installation very convenient. Moreover, since the first and second magnetic strips are not glued to the window frame and sash, they will not fall off even after long-term use, thus having a long service life. At the same time, the adhesive shell and the fastening plastic shell can also protect the magnetic strips well and slow down the aging process of the magnetic strips, thus giving the magnetic strips a very long service life.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, this utility model provides a magnetic suction structure for sliding doors and windows that is dustproof, soundproof, and noise-reducing. To achieve the purpose proposed by this utility model, it includes a window frame vertical frame 1 with an inner recess 10 for mounting the window sash vertical frame. A first magnetic strip mounting groove 11 arranged along its height direction is also provided in the inner recess 10; a first magnetic strip body 3 composed of a plastic shell 31 and a first magnetic strip 32 covered in the plastic shell 31; the first magnetic strip body 3 is installed in the inner recess 10 by the plastic shell 31 and the first magnetic strip mounting groove 11 being fitted together, and an elastic buffer part 33 is also provided on the outer side of the plastic shell 31; a window sash vertical frame 2 with an outer fastening groove 20; and a second magnetic strip body 4 composed of a fastening plastic shell 41 and a second magnetic strip 42 covered in the fastening plastic shell 41. The second magnetic strip body 4 is installed on the window sash vertical frame 2 by the fastening plastic shell 41 and the outer fastening groove 20 being fastened together. When the doors and windows are closed, the direction of the magnetic attraction between the two magnetic strips is on the same straight line as the direction of the compression of the elastic buffer part 33, which causes the elastic buffer part 33 to be subjected to greater compression deformation, so that the vertical frame 2 of the window sash and the vertical frame 1 of the window frame are tightly fitted together, which better isolates external noise and dust. The elastic buffer part 33 is preferably made of hollow soft rubber, so that it is easier to deform and form a larger sealing surface when compressed, which helps to improve the sealing between the window sash and the window frame. At the same time, the elastic buffer part 33 extends out of the outer side of the first magnetic strip mounting groove 11 and is placed between the vertical frame 1 of the window frame and the vertical frame 2 of the window sash, which can also prevent the window sash from hitting the window frame when closed.

[0028] Furthermore, for ease of assembly, such as Figures 1 to 5 As shown, the two sides of the adhesive shell 31 are respectively provided with mounting protrusions 311, and the two sides of the first magnetic strip mounting groove 11 are respectively provided with mounting grooves 111 for mounting the mounting protrusions 311.

[0029] Furthermore, such as Figures 1 to 5As shown, the cross-sectional width d1 of the mounting protrusion 311 is smaller than the cross-sectional width d2 of the mounting groove 111, so that the mounting protrusion 311 can be movably mounted in the mounting groove 111; the bottom of the first magnetic strip mounting groove 11 is also provided with a reset magnetic strip 5 that attracts the first magnetic strip body 3. In this way, when the window sash vertical frame 2 is close to the first magnetic strip body 3 of the window frame, even if the user does not push the window sash vertical frame 2 into place, under the action of magnetic attraction, the elastic deformation part 33 will move outward and fit against the second magnetic strip body 4 to form a sealing structure. When the window sash vertical frame 2 is pushed or pulled open, the reset magnetic strip 5 attracts the first magnetic strip body 3 to move inward, and the elastic deformation part 33 is pulled back to the opening of the first magnetic strip mounting groove 11 to prevent dust from entering the first magnetic strip mounting groove 11.

[0030] like Figure 7 As shown, in order to conveniently install the reset magnetic strip 5 inside the vertical frame 1 of the window frame, the reset magnetic strip 5 is composed of a third magnetic strip 51 and a plastic cover 52 covering the surface of the third magnetic strip 51. The plastic cover 52 is also provided with a buckle part 521 on both sides. The bottom of the first magnetic strip mounting groove 11 is also provided with a mounting bottom groove 112. The reset magnetic strip 5 is installed in the bottom of the first magnetic strip mounting groove 11 by the buckle part 521 and the mounting bottom groove 112.

[0031] The vertical frame 2 of the window sash can be a common aluminum alloy vertical frame structure, in which case the outer fastening groove 20 and the vertical frame 2 of the window sash are an integral structure. The vertical frame 2 of the window sash can also be a thermally broken aluminum structure. To install the second magnetic strip 4 on the thermally broken aluminum door and window, such as... Figures 1 to 3 as well as Figure 8 , 9 As shown, it also includes a plastic strip 6 with an outer fastening groove 20. The vertical frame 2 of the window sash is composed of a front assembly part 21, a rear assembly part 22, and a thermally broken plastic connecting strip 23 connecting the front assembly part 21 and the rear assembly part 22. The plastic strip 6 is fastened into the fastening groove 24 formed by the outer end faces of the front assembly part 21 and the rear assembly part 22. In this way, the vertical frame 2 of the window sash is a thermally broken aluminum structure, which has a good heat insulation and sound insulation effect, thereby making the window have a better sound insulation effect and more energy-saving.

[0032] Furthermore, in order to quickly assemble the plastic groove strip 6 onto the vertical frame 2 of the window sash, hook portions 61 are provided on both sides of the plastic groove strip 6, and corresponding fastening protrusions 241 are provided on both sides of the fastening groove 24 to fasten the hook portions 61.

[0033] like Figure 6 As shown, in order to facilitate the installation of the second magnetic strip 4 onto the outer fastening groove 20, a hook portion is also provided on the second magnetic strip 4, and a corresponding fastening protrusion is also provided on the outer fastening groove 20.

[0034] The snap-on plastic shell 41 is preferably made of rigid plastic and is flush with the outer side of the window sash vertical frame 2, which makes the structure of the window sash vertical frame 2 neater and of better quality.
