Description

Technical Field

[0001] This utility model relates to the field of hanging sliding door technology, specifically to the double-wheel self-parallel bouncing wheels under the hanging sliding door. Background Technology

[0002] A sliding door is a type of door that can slide left and right or up and down along a track parallel to the wall to achieve space division or the opening and closing of entrances and exits. It is mainly composed of the door body, track, pulleys, and door frame (some have this). The door body is the main part of the sliding door, and its materials are diverse, such as wood, glass, aluminum alloy, and PVC. The shape and size can be customized according to the requirements of the actual installation site. Generally, there are single-leaf, double-leaf, or multi-leaf combinations.

[0003] Existing sliding doors typically have a floor track, which makes adjusting the door panel's flatness convenient, but floor tracks can be inconvenient for household cleaning. To address this, we have proposed a new type of sliding door with double-wheel self-parallel spring-loaded rollers for use on floor-track sliding doors, especially for extremely narrow profiles. The new product features a slider to adjust the door's balance, and its trackless design makes daily cleaning much easier. Utility Model Content

[0004] The purpose of this utility model is to provide a double-wheel self-parallel spring-loaded roller under the sliding door to solve the problem mentioned in the background art that existing linkage sliding doors are generally designed with a floor track. Although the flatness of the door leaf is convenient to adjust, it is inconvenient for cleaning at home. Therefore, we propose a double-wheel self-parallel spring-loaded roller under the sliding door for use on sliding linkage doors with floor tracks, especially for extremely narrow profiles. The new product is designed with a slider, which can mainly adjust the balance of the door and window. The trackless design makes daily cleaning more convenient. To achieve the above objectives, this utility model provides the following technical solution: a double-wheel self-parallel bouncing wheel for a sliding door, comprising a housing, the interior of which is designed with a sliding cavity; a tail plug is movably connected to one side of the interior of the housing; an inner shell is fixedly connected to one side of the tail plug; a brush is fixedly connected to the interior of the inner shell; a wheel is movably connected to the interior of the inner shell; a slider is movably connected to one side of the inner shell; the other side of the slider is provided with the same brush, inner shell, and wheel; a pull head is fixedly connected to the other side of the interior of the housing; a screw is movably connected to one side of the pull head; a connecting spring is movably connected to the side surface of the screw; by adjusting the screw to pull the pull head, the inner shell moves up and down within the sliding grooves of the slider, pull head, and tail plug, allowing the floor wheel to freely adjust the height of the door leaf. When the floor wheels glide on the ground, they may collide with debris that could be present. Therefore, a floor brush is designed to protect the wheels and make them glide more smoothly, especially when used on extremely narrow profiles. The new product is also designed with a slider to adjust the balance of doors and windows. The trackless design makes daily cleaning convenient.

[0005] Further preferably, the bottom of the outer casing has an installation groove, and two connecting grooves are respectively opened on both sides of the outer casing. Connecting screws are movably connected to both sides of the tail plug. The connecting screws are located inside the connecting grooves. Sliding grooves are respectively opened on both sides of the outer casing, which can effectively reduce the noise generated by the sliding door during opening and closing. Its design and materials can usually make the fit between the roller and the track tighter and smoother, reduce jamming and friction, make the opening and closing of the sliding door easier and smoother, improve the convenience of use, have good load-bearing capacity and structural stability, and can better withstand the weight of the door and the external impact in daily use.

[0006] More preferably, the two grooves are symmetrically distributed on both sides of the outer casing, and mounting screws are movably connected to both sides of the slider. The two mounting screws are movably connected inside the grooves, and a rotating shaft is movably connected inside the wheel.

[0007] More preferably, two sliding grooves are respectively provided on both sides of the outer casing, and the two sliding grooves are symmetrically distributed on both sides of the outer casing. Fixing screws are movably connected to both sides of the pull head.

[0008] More preferably, the fixing screws are movably connected inside the sliding groove, and a threaded groove is provided on one side of the outer casing.

[0009] More preferably, the screw is located inside the threaded groove, a base is fixedly connected to the bottom of the housing, a limit plate is movably connected to the side surface of the screw, and a fixing block is movably connected to the side surface of the screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In this invention, a connecting spring runs through the inner side of the adjusting screw. By pressing the connecting spring with the adjusting screw, a certain force is generated between the pull head and the inner shell, making the wheel slide more easily and smoothly on the ground, improving the convenience of use, and unaffected by load. This device is used for the spring-loaded wheel of a sliding door, installed below the sliding door and in contact with the ground. Its function is to prevent the door from swinging and to make the door slide more smoothly. The connecting spring presses the pull head to generate a certain force, and the elasticity of the connecting spring makes the wheel automatically contact the ground.

[0012] In this invention, by adjusting the screw to pull the pull head, the inner shell moves up and down within the grooves of the slider, pull head, and tail plug, allowing the floor wheel to freely adjust the height of the door leaf. Since debris may collide with the floor wheel when it slides on the ground, a floor brush is designed to protect it and ensure smoother wheel movement, especially useful on extremely narrow profiles. The new product also features a slider to adjust the balance of the door and window, and a trackless design for convenient daily cleaning.

[0013] This invention effectively reduces the noise generated during the opening and closing of sliding doors. Its design and materials typically allow for a tighter and smoother fit between the rollers and the track, reducing jamming and friction, making the opening and closing of sliding doors easier and smoother, improving ease of use, and possessing good load-bearing capacity and structural stability, enabling it to better withstand the weight of the door and external impacts during daily use.

[0023] The usage and advantages of this utility model: The double-wheeled self-parallel bouncing wheel under the sliding door operates as follows:

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, by adjusting the screw 7 to pull the pull head 6, the inner shell 4 moves up and down within the slide groove 203 of the slider 9, the pull head 6, and the tail plug 2, allowing the floor wheel to freely adjust the height of the door leaf. When the wheel 5 slides on the ground, it is easy for debris on the ground to collide with the floor wheel. Therefore, a brush 3 is designed. The brush 3 mainly protects the wheel 5 to make the sliding smoother, especially when used on extremely narrow profiles. The new product is designed with a slider 9, which can mainly adjust the balance of the door and window. The trackless design makes daily cleaning convenient and can effectively reduce the noise generated by the sliding door during opening and closing.

It has good load-bearing capacity and structural stability, and can better withstand the weight of the door and the impact of external forces during daily use. A connecting spring 12 runs through the inside of the adjusting screw 7. By adjusting the screw 7 and compressing the connecting spring 12, a certain force is generated between the pull head 6 and the inner shell 4, making the wheel 5 slide more easily and smoothly on the ground, improving ease of use and unaffected by load. This device is used for the spring-loaded wheel of the sliding door. It is installed below the sliding door and in contact with the ground. Its function is to prevent the door from swinging and to make the door slide more smoothly. The connecting spring 12 compresses the pull head 6 to form a certain force. Through the elasticity of the connecting spring 12, the wheel 5 automatically contacts the ground.
