Abstract
Description
Technical Field
[0001] This utility model relates to the field of sliding door technology, specifically to a sliding door lower track cover plate. Background Technology
[0002] Sliding doors typically have an upper track and a lower track, with the door sliding between them. Because the lower track is installed on the ground, debris and other contaminants can easily get into it, affecting its operation. Additionally, the inner track of the lower track has a height difference from the ground, making it easy for pedestrians to trip, especially those wearing high heels or other pointed shoes, which could get stuck, thus compromising pedestrian safety. Utility Model Content
[0003] The purpose of this utility model is to provide a sliding door lower track cover plate to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding door lower rail cover plate, installed on the side of the sliding door lower rail track, including a motor, a slide table, a connecting table, a universal joint, a base, and a cover plate. The slide table is driven by the motor to reciprocate along the lower rail. The connecting table is disposed on the slide table. The universal joint connects the connecting table and the base. The base has rotating shafts on both sides. The base is connected to the lower rail through the rotating shafts. The cover plate is disposed on the base.
[0005] Preferably, the cover plate includes a first cover plate, a second cover plate, and a third cover plate, wherein the first cover plate, the second cover plate, and the third cover plate are arranged along the track length direction of the lower slide rail.
[0006] Preferably, the bottom end face of the cover plate is provided with a sealing strip.
[0007] Preferably, the base includes a first seat and a second seat, and a cover plate mounting seat is provided between the first seat and the second seat, and the cover plate is mounted on the cover plate mounting seat.
[0008] Preferably, the bottom end of the first base is provided with a rocker arm, which is connected to a universal joint.
[0009] Preferably, a limiting block is provided on the side of the rocker arm away from the universal joint.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a structure including a motor, a slide, a connecting platform, a universal joint, a base, and a cover plate, this utility model brings about many beneficial effects:
[0011] Preventing debris from entering: The cover plate can cover the inner track of the sliding door when it is opened, effectively preventing debris and other foreign objects from entering the sliding track and avoiding them from affecting the normal operation of the sliding track, thus ensuring smooth opening and closing of the sliding door. For example, for a sliding door with three inner tracks, the first, second, and third cover plates can cover the three inner tracks respectively, specifically preventing debris from entering each track.
[0012] Improving pedestrian safety: The inner track of the sliding door has a height difference from the ground, but the cover plate makes it almost flush with the ground. This means that pedestrians do not need to deliberately avoid the sliding track when entering or exiting the sliding door, reducing the risk of tripping, and especially preventing shoes with sharp soles such as high heels from getting stuck, thus ensuring pedestrian safety.
[0013] Enhanced sealing: The bottom surface of the cover plate is equipped with a sealing strip. When the sliding door is open and the cover plate is upright on one side of the door, the sealing strip can form a seal between the sliding door and the cover plate, which helps to prevent dust and other substances from entering the room and improve the cleanliness of the environment.
[0014] Flexible and adaptable structure: The number of cover plates can be flexibly set according to the width of the lower slide rail and the number of inner tracks, which can adapt to different specifications of lower slide rails; at the same time, the cover plate mounting base is detachably connected to the first and second base bodies, which facilitates the installation, replacement and maintenance of the cover plates.
[0015] Stable and reliable operation: The cover plate is raised and lowered by a motor-driven slide table in conjunction with a connecting table, universal joint, rocker arm, and other structures, ensuring stable operation. Furthermore, the rocker arm is equipped with a limit block to restrict its swing range, guaranteeing the accuracy and reliability of the cover plate's movement, and thus ensuring the stable operation of the entire device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 This utility model provides a technical solution: a sliding door lower rail cover plate, installed on the side of the sliding door lower rail track, including a motor 1, a slide table 2, a connecting platform 3, a universal joint 4, a base 5 and a cover plate 6. The slide table 2 is driven by the motor 1 to reciprocate along the lower rail. The connecting platform 3 is disposed on the slide table 2. The universal joint 4 is connected between the connecting platform 3 and the base 5. The base 5 has rotating shafts 7 on both sides. The base 5 is connected to the lower rail through the rotating shafts 7. The cover plate 6 is disposed on the base 5.
[0020] In an embodiment of this utility model, for example, a sliding rail with three inner tracks, the cover plate 6 includes a first cover plate 61, a second cover plate 62, and a third cover plate 63, which are arranged along the length of the sliding rail. The first cover plate 61, the second cover plate 62, and the third cover plate 63 can cover the three inner tracks respectively, preventing debris from entering the tracks and affecting the opening and closing of the sliding door. Furthermore, after covering the inner tracks, the first cover plate 61, the second cover plate 62, and the third cover plate 63 form an almost flush plane with the ground, so that pedestrians do not need to deliberately avoid the sliding rail when entering and exiting the sliding door, and also preventing accidents caused by the drop in the inner tracks of the sliding rail. The number of cover plates 6 can be flexibly set according to the width of the sliding rail and the number of inner tracks within the sliding rail.
[0021] In an embodiment of this utility model, a sealing strip is provided on the bottom end face of the cover plate 6. When the sliding door is open, the cover plate 6 stands upright on one side of the door, and due to the action of the sealing strip, a sealed state is formed between the sliding door and the cover plate 6.
[0022] In an embodiment of this utility model, the base 5 includes a first base 51 and a second base 52, with a cover plate mounting seat 53 provided between the first base 51 and the second base 52, and the cover plate 6 mounted on the cover plate mounting seat 53. The cover plate mounting seat 53 is detachably connected to the first base 51 and the second base 52.
[0023] In an embodiment of this utility model, the bottom end of the first base 51 is provided with a rocker arm 54, which is connected to the universal joint 4.
[0024] In an embodiment of this utility model, a limiting block 55 is provided on the side of the rocker arm 54 away from the universal joint.
[0025] In an embodiment of this utility model, when the sliding door is opened, the motor 1 drives the slide 2 to slide, the connecting platform 3 moves, and the universal joint 4 drives the rocker arm to swing, rotating the base and causing the cover plate 6 to descend along the lower rail with the base as the fulcrum until it completely covers the lower rail. Conversely, when the sliding door is closed, the motor 1 drives the slide 2 in the opposite direction, causing the cover plate 6 to stand upright.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
