Description

Technical Field

[0001] The utility model belongs to the technical field of sliding doors, in particular to an anti-slip sliding door. Background Art

[0002] As the name implies, a sliding door is a door that can be pushed and pulled, also known as a sliding door. It moves on a fixed track through the door leaf connected to the pulley, which is different from a hinged swing door. Sliding doors have the characteristics of being reusable and industrially produced. They can be used as partition doors for kitchen partitions, balcony partitions, bathroom partitions, etc., and can also be used as cabinet doors for custom wardrobes, etc.;

[0003] The movement of sliding doors is inseparable from the use of guide rails and some rollers. The existing sliding door guide rails are an integrated setting. During the installation process, the rollers need to be installed first, and then the door body is installed. The installation efficiency is low, and the rollers are prone to derailment. Therefore, an anti-slip sliding door is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-slip sliding door. Through the coordinated use of a fixed guide rail and a limiting guide rail, when installing the door frame, the fixed guide rail can be installed first, thereby facilitating the guide rail on the door frame to enter the fixed guide rail, making the installation simpler and faster, and improving the installation efficiency. At the same time, the limiting plate can be used to limit the roller, thereby preventing the roller from derailing, improving the safety of use, and solving the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] An anti-slip sliding door comprises: a door frame and a fixed guide rail, wherein the top length of the fixed guide rail is greater than the bottom length, a plurality of fixed frames are fixedly connected to the top of the door frame, and at least one roller is rotatably connected to one side of each fixed frame, and a bent extension part for limiting the position of the roller is provided on one side of the bottom of the fixed guide rail, and the roller slides on the inner wall of the bottom of the fixed guide rail;

[0007] It also includes a limiting guide rail arranged on one side of the fixed guide rail, and a limiting plate for limiting the height of the roller is fixedly connected to the inner wall of one side of the limiting guide rail. Through the coordinated use of the fixed guide rail and the limiting guide rail, when installing the door frame, the fixed guide rail can be installed first, which makes it convenient for the guide rail on the door frame to enter the fixed guide rail, making the installation simpler and faster, and improving the installation efficiency. A plurality of fixing components for fixing the limiting guide rail are arranged between the fixed guide rail and the limiting guide rail.

[0008] As a further scheme of the utility model, the fixing assembly includes an internal threaded sleeve, a first perforation, a second perforation and a fixing bolt, the internal threaded sleeve is fixed to an inner wall of one side of the fixed guide rail, the first perforation is arranged on one side of the limiting guide rail, the second perforation is arranged on one side of the limiting plate, the fixing bolt passes through the first perforation and the second perforation and is threadedly connected to the internal threaded sleeve, and by installing the limiting plate in the limiting guide rail, after the limiting guide rail is installed, the limiting plate can be used to limit the roller, thereby preventing the roller from derailing and improving the safety of use.

[0009] As a further solution of the utility model, the bottoms of the fixed guide rail and the limiting guide rail are fixedly connected with decorative panels.

[0010] As a further solution of the utility model, a plurality of fixing holes are opened on the top of the fixed guide rail, and expansion bolts for installing the fixed guide rail are arranged in the fixing holes.

[0011] As a further solution of the utility model, a plurality of avoidance grooves for avoiding the expansion bolts are arranged on one side of the limit plate.

[0012] As a further solution of the present invention, a glass door body is installed in the door frame.

[0013] In the present application, during installation, the fixed guide rail is first installed on the top of the door opening. During installation, it is installed and fixed by expansion bolts. After the fixing is completed, the fixing frame and the roller are assembled on the door frame on the ground, and then the door frame is erected. After the roller contacts the inner wall of the top of the fixed guide rail, the door frame is pushed toward the inner wall of the fixed guide rail, and then the door frame is released, so that the roller falls into the fixed guide rail. The installation is simpler and faster, and then the roller on the door frame is positioned. During positioning, the limiting guide rail is installed on one side of the fixed guide rail, and then the fixing bolt is passed through the first perforation and the second perforation and then threadedly connected with the internal threaded sleeve, thereby completing the fixation of the limiting guide rail. The limiting plate on one side of the limiting guide rail is located above the roller, thereby limiting the roller to prevent the roller from derailing and improving the safety of use.

[0014] The embodiments of the present invention have the following beneficial effects:

[0015] In the utility model, by using the fixed guide rail and the limit guide rail in coordination, when installing the door frame, the fixed guide rail can be installed first, thereby facilitating the guide rail on the door frame to enter the fixed guide rail, making the installation simpler and faster, and improving the installation efficiency;

[0016] In the utility model, by installing the limit plate in the limit guide rail, after the limit guide rail is installed, the limit plate can be used to limit the roller, thereby preventing the roller from derailing, thereby improving the safety of use;

[0017] In the utility model, through the coordinated use of the fixed guide rail and the limiting guide rail, when installing the door frame, the fixed guide rail can be installed first, thereby facilitating the guide rail on the door frame to enter the fixed guide rail, making the installation simpler and faster, and improving the installation efficiency. At the same time, the limiting plate can be used to limit the roller, thereby preventing the roller from derailing, thereby improving the safety of use.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
