Abstract
Description
Technical Field
[0001] The utility model relates to the field of sliding doors, in particular to a structure of a heavy-duty narrow-edge sliding door. Background Art
[0002] Due to its simple and generous design and space-saving feature, sliding doors are widely used indoors. However, due to the unreasonable design of the door leaf frame part of traditional sliding doors, the width is relatively large, resulting in a small glass area and an inability to further increase the light transmission.
[0003] Secondly, the door lock of a sliding window is generally embedded in the fan frame and is difficult to be used as a handle.
[0004] In addition, traditional screen fans are mainly used for window screens. Except for the fan frame part, the middle is entirely a screen mesh. However, if the screen fan is used as a door body, due to the large height span of the screen mesh and the relatively soft screen mesh material, the middle lacks support and is prone to deformation. Content of the Utility Model
[0005] The purpose of the utility model is to provide a structure of a heavy-duty narrow-edge sliding door, which reduces the widths of the first fan frame and the second fan frame and improves the light transmission of the glass fan and the screen fan.
[0006] To achieve the above purpose, the utility model provides a structure of a heavy-duty narrow-edge sliding door, which includes a door vertical frame, a first glass fan and a screen fan. At least one side of the first glass fan is provided with a first fan frame. The length of the cross-section of the first fan frame is L, and the width is W1, and W1 is not greater than L. An inner concave part is provided on the inner side of the door vertical frame. One end of the first fan frame extends into the inner side of the inner concave part. A second fan frame is provided on the side of the first glass fan away from the door vertical frame. The width of the cross-section of the second fan frame is W2, and W2 is less than W1. Second fan frames are provided on both left and right side edges of the screen fan.
[0007] As a further improvement of the utility model, the length L of the cross-section of the first fan frame ≤ 60 mm.
[0008] As a further improvement of the utility model, a first installation groove and an inner groove are respectively provided on both sides of the first fan frame. A second installation groove is provided at the bottom of the inner groove. The edge of the first glass fan is embedded in the first installation groove. A convex part is provided in the middle of the bottom of the inner concave part of the door vertical frame. The convex part of the door vertical frame extends into the inner groove of the first fan frame adjacent to it. A first dust-proof strip is provided between the inner wall of the inner concave part and the outer wall of the first fan frame. A second dust-proof strip is provided between the inner side of the inner groove and the outer side of the convex part. A shock-absorbing strip is also provided at the bottom of the inner concave part.
[0009] As a further improvement of the present utility model, a key lock is provided on the first frame of the first glass sash. The key lock includes two lock housings respectively connected to the front and back end faces of the first frame. The lock housings protrude from the end face of the first frame. A toggle slot is slidably connected up and down in the middle of each lock housing, and keys linked with the toggle slots are provided at the upper and lower ends of each lock housing. The key lock further includes a sliding member slidably engaged with the second installation groove of the first frame. A toggle rod simultaneously engaged with the toggle slots of the two lock housings is connected to one side of the sliding member, and a lock body is provided on the other side of the sliding member. A lock groove is provided on the end face of the protruding portion, and the lock body moving up and down with the sliding member is engaged with the lock groove.
[0010] As a further improvement of the present utility model, at least one side of the second frame is provided with an L-shaped extension portion, and a first sealing strip is installed inside the L-shaped extension portion. A third installation groove is provided inside the second frame, and the edge of the first glass sash is embedded in the third installation groove of the second frame adjacent to it.
[0011] As a further improvement of the present utility model, a cover plate is buckled at the third installation groove of the second frame corresponding to the screen sash, and a pressing strip is provided inside the cover plate. The edge of the screen of the screen sash passes through the gap between the cover plate and the opening of the third installation groove and is pressed by the pressing strip at the bottom of the third installation groove.
[0012] As a further improvement of the present utility model, a horizontally arranged middle waist is provided in the middle of the screen sash. The two ends of the middle waist are connected to the second frames on both sides of the screen sash. Fourth installation grooves are provided on both the upper and lower sides of the middle waist, and cover plates are buckled at the fourth installation grooves. The edge of the screen passes through the gap between the cover plate and the opening of the fourth installation groove and is pressed by the pressing strip at the bottom of the fourth installation groove.
[0013] As a further improvement of the present utility model, the first frames are provided at both the top and bottom of the first glass sash and the screen sash. An upper pulley is installed in the second installation groove of the first frame at the top, and a lower pulley is installed in the second installation groove of the first frame at the bottom.
[0014] Beneficial effects
[0015] Compared with the prior art, the advantages of the heavy-duty narrow-edge sliding door structure of the present utility model are as follows:
[0016] 1. In the cross-section of the first frame, the width W1 is not greater than the length L, and the cross-section width W2 of the second frame is less than W1, which is beneficial to increasing the light transmission area of the glass sash and the screen sash and improving the light transmission amount of the glass sash and the screen sash.
[0017] 2. The shock-absorbing strip in the concave portion of the door vertical frame plays a buffering role for the first frame, preventing direct collision between the door vertical frame and the first frame. The first dust-proof strip and the second dust-proof strip are beneficial to isolating dust.
[0018] 3. In the button lock, the two lock housings protrude from the front and back end faces of the first door frame respectively and can be used as handles. By pressing the button at the upper or lower end of the lock housing, the sliding member can be driven to drive the lock body to move up and down. When the lock body is engaged with the lock groove on the protruding part of the door vertical frame, the glass fan is locked and cannot slide. When the lock body is disengaged from the lock groove, the glass fan can slide.
[0019] 4. The first sealing strip of the second door frame is located inside the L-shaped extension part. When the second door frames of the two door leaves approach each other, the end of the L-shaped extension part of one second door frame contacts the first sealing strip of the other second door frame, resulting in a better sealing effect. At the same time, people cannot see the first sealing strip from the front, and the flatness of the door leaf is better.
[0020] 5. The second door frame can be commonly used on the glass fan and the screen fan, reducing the number of profiles and facilitating the reduction of the development and manufacturing costs. The second door frame and the middle waist share the same cover plate, further reducing the development and manufacturing costs.
