Description

Technical Field

[0001] This invention relates to the field of sliding door technology, and more particularly to a two-track sliding door. Background Technology

[0002] Sliding doors are a common type of door in homes, referring to doors that can be pushed and pulled. Rollers are the most important hardware component of sliding doors, and there are three main types of rollers on the market: plastic, metal, and fiberglass. Metal rollers are strong, but they can easily generate noise when in contact with the track. Carbon fiber fiberglass rollers contain roller bearings, ensuring smooth sliding and are wear-resistant and durable. Based on the materials used in their construction, sliding doors can be categorized as metal sliding doors, glass sliding doors, color steel sliding doors, aluminum alloy doors, and solid wood sliding doors, among others. They offer advantages such as separating space, providing appropriate sound insulation, blocking views, enhancing privacy, increasing spatial flexibility, creating open spaces, and offering rich visual effects. In terms of materials, they can be made of wood, metal, organic materials, and inorganic materials (such as glass). Applications include wardrobes, bookcases, wall cabinets, and doors for bedrooms, living rooms, and showrooms. In these applications, sliding doors have become increasingly diverse and versatile. Besides the most common partition doors, sliding doors are widely used in bookcases, wardrobes, living rooms, showrooms, and sliding entrance doors. Nowadays, people generally choose titanium-magnesium-aluminum alloy sliding doors because they are low-carbon and environmentally friendly, moderately priced, and highly decorative, making them suitable for installation in damp environments such as bathrooms and kitchens. They are sturdy, come in a variety of colors and patterns, and have a wide selection of glass types, while being more economical than other types of sliding doors. They are the first choice for ordinary families.

[0003] A two-track sliding door is a sliding door with two tracks, in which the two door panels move on the two tracks respectively.

[0004] During use, sliding doors accumulate a lot of dust and impurities in the tracks, affecting the smoothness of the sliding doors. The track grooves are also narrow, making it difficult to clean with a broom or vacuum cleaner. Summary of the Invention

[0005] This invention discloses a two-track sliding door, which aims to solve the technical problem in the prior art that it is difficult to clean dust and impurities in the track groove of sliding doors.

[0006] This invention proposes a dual-track sliding door, comprising two door bodies, each with a functional slot, and a cleaning component housed within each functional slot. The cleaning component includes a side-mounted drive seat and a side-mounted retaining seat, both movably connected to the door bodies. Each side-mounted drive seat and retaining seat has a circular hole, with a movably connected a traction shaft inside the hole on the side-mounted drive seat and a movably connected retaining shaft inside the hole on the side-mounted retaining seat. Both the traction shaft and retaining shaft have short shafts movably connected inside them, with a geared disc fixedly connected to the other end of each short shaft. A common chain connects the two geared discs, and a brush belt is fixedly connected to the outside of the chain, with soft brushes attached to the outside of the brush belt.

[0007] Equipped with a cleaning component, the sliding door tracks are brushed and dusted inside, removing dust and impurities that adhere to the tracks and moving them to one end for easy centralized cleaning. Simultaneously, the sliding door can be moved during the brushing process, allowing for cleaning of different sections of the tracks and improving cleaning effectiveness. The wheel, actuating shaft, and retaining shaft can slide together, facilitating the complete storage of the cleaning component within the functional slot and preventing interference with daily use of the sliding door.

[0008] In a preferred embodiment, the side-mounted drive seat has a circular slot, and a drive shaft is movably connected inside the circular slot. The drive shaft is located above the traction shaft. A hexagonal insertion hole is provided on the side of the drive shaft away from the side-mounted drive seat. Both the drive shaft and the traction shaft are fixedly connected to a wheel, and a belt is provided between the two wheel. An internal bracket is fixedly connected to the upper side of both the side-mounted drive seat and the side-mounted retaining seat. The internal bracket has a circular insertion hole. The door body has four locking holes, which are symmetrically distributed in pairs. Adjusting rods are provided on the outer sides of both the side-mounted drive seat and the side-mounted retaining seat. One end of each adjusting rod passes through a locking hole and the circular insertion hole of the internal bracket and is movably connected to the inner wall of the door body.

[0009] The side-mounted drive seat and side-mounted retainer are conveniently placed and stored by the addition of an adjustment rod, built-in bracket, and locking holes.

[0010] In a preferred embodiment, the door body is provided with a side attachment groove, which is located on one side of the side attachment drive seat, and a dust removal component is provided inside the side attachment groove. The dust removal component includes a dust removal plate and multiple dust scrapers. The dust removal plate and the multiple dust scrapers are fixedly connected, and the dust removal plate is movably connected to the side attachment groove. Two cylindrical holes are provided inside the side attachment groove, and sliding rods are fixedly connected to the inner walls of the cylindrical holes. Two circular holes are provided on the side of the dust removal plate near the side attachment groove. The two sliding rods are movably connected to the inner walls of the two circular holes of the dust removal plate, respectively. Retracting springs are movably connected to the outside of the two sliding rods. The two ends of the retracting springs are fixedly connected to the inner wall of the side attachment groove and the outer wall of the dust removal plate, respectively. An installation groove is provided on the side of the dust removal plate away from the side attachment groove. A circular hole is provided in the installation groove, and a positioning plate is movably connected inside the circular hole. A positioning groove is provided on one side of the side attachment groove, and the positioning plate is located inside the positioning groove.

[0011] By incorporating a dust removal component, the dust scraper on the dust removal plate contacts the rotating soft brush, scraping off the dust and impurities adhering to the soft brush. This prevents the soft brush from being hindered by excessive dust and impurities, thus further improving the cleaning effect of the soft brush. The elasticity of the storage spring facilitates the removal and storage of the dust removal plate.

[0012] In a preferred embodiment, the exterior of the door is provided with an adapter seat, which is snapped into the door. A motor is fixedly connected to the adapter seat, and the output end of the motor is connected to a reduction gearbox via a coupling. The reduction gearbox is provided with a rotating shaft, and the top of the rotating shaft is provided with a hexagonal insert, which is movably connected to the hexagonal insertion hole of the drive shaft. A sealing plate is provided on the exterior of the functional slot, and the sealing plate is fixedly connected to the door. Tempered glass is provided on the door. Track grooves are provided on the upper and lower sides of both doors, and the outer sides of both doors are provided with the same door frame. Two tracks are provided on the inner walls of the upper and lower sides of the door frame, and the two doors are movably connected to the two tracks respectively.

[0013] In a preferred embodiment, the door frame is provided with two loading and unloading components, which are staggered. Each loading and unloading component includes a loading and unloading groove and a sealing plate. The loading and unloading groove is located on the door frame and has multiple equidistant recesses. Each recess has a top block inside, and a return spring is fixedly connected between the top block and the bottom inner wall of the recess. The sealing plate has multiple equidistant protrusions on its lower side, which are movably connected to the recesses. The sealing plate has two symmetrical screw holes, and screws are provided between the sealing plate and the door frame.

[0014] By incorporating a loading and unloading assembly, dust and impurities can be removed from the opening in the loading and unloading groove after the sealing plate is removed. This facilitates the removal of dust and impurities from the track groove, preventing situations where the sliding door track groove is too deep and internal dust and impurities cannot be completely removed.

[0015] As can be seen from the above, the double-track sliding door provided by the present invention has a matching self-cleaning tool, that is, the cleaning component is used to brush and dust the inside of the sliding door track, and the dust and impurities adhering to the track are brushed off and moved to one end for convenient centralized treatment. At the same time, the sliding door can be moved during the brushing process to perform cleaning operations on different positions of the sliding door track, thereby improving the cleaning effect of the sliding door track.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] The present invention discloses a dual-track sliding door, which is mainly used in scenarios where dust and impurities are difficult to clean from the sliding door track groove.

[0027] Reference Figure 1-4 A double-track sliding door includes two door bodies 1, each with a functional slot 2. Each functional slot 2 contains a cleaning component 3. The cleaning component 3 includes a side-mounted drive seat 301 and a side-mounted retaining seat 302, both slidably connected to the door bodies 1. Both the side-mounted drive seat 301 and the side-mounted retaining seat 302 have circular holes, and the circular holes in the side-mounted drive seat 301 are rotated by bearings. A traction shaft 305 is connected to a retaining shaft 306, which is rotatably connected to the round hole on the side retaining seat 302 via a bearing. Both the traction shaft 305 and the retaining shaft 306 are slidably connected to a short shaft. The other end of each short shaft is connected to a gear disc 304 via bolts. The same chain 303 is provided between the two gear discs 304. A brush belt 307 is connected to the outside of the chain 303 via bolts, and a soft brush 308 is provided on the outside of the brush belt 307.

[0028] Specifically, when cleaning the sliding door track, the functional slot 2 is opened, and the brush belt 307 is pulled out so that the short shafts on the two toothed discs 304 slide out from the driving shaft 305 and the fixing shaft 306 respectively. The chain 303, together with the brush belt 307, extends out from the functional slot 2. Then, the side drive seat 301 and the side fixing seat 302 are adjusted to move them down, and the soft brush 308 outside the brush belt 307 contacts the sliding door track. After the cleaning component 3 is removed, a driving force is applied to the toothed disc 304 to make it rotate, which drives the chain 303 to rotate. The brush belt 307 rotates, and the soft brush 308 brushes the inside of the track. During the brushing process, the door body 1 is moved slowly to achieve cleaning of different positions of the track. The dust and impurities after brushing are concentrated on one side of the track for further processing.

[0029] In specific application scenarios, the cleaning component 3 is suitable for cleaning and dust removal inside the sliding door track. That is, the cleaning component 3 is used to brush and dust the inside of the sliding door track, removing dust and impurities adhering to the track and moving them to one end for easy centralized treatment. At the same time, the sliding door can be moved during the brushing process to perform cleaning operations on different positions of the sliding door track, improving the cleaning effect of the sliding door track. The wheel 5 can slide between the driving shaft 305 and the fixing shaft 306, making it easy for the cleaning component 3 to be stored in the functional slot 2, avoiding affecting the daily use of the sliding door.

[0030] Reference Figure 1 , Figure 3 and Figure 4 A circular slot is provided on the side drive seat 301. The drive shaft 4 is rotatably connected to the inside of the circular slot via a bearing. The drive shaft 4 is located above the traction shaft 305. A hexagonal insertion hole is provided on the side of the drive shaft 4 away from the side drive seat 301. Both the drive shaft 4 and the traction shaft 305 are bolted to the outside of a wheel 5. A belt 6 is provided between the two wheel 5. The upper sides of the side drive seat 301 and the side fixed seat 302 are bolted to an internal bracket 7. The internal bracket 7 is provided with a circular insertion hole. The door body 1 has four locking holes 8, which are symmetrically distributed in pairs. Adjusting rods 9 are provided on the outer sides of the side drive seat 301 and the side fixed seat 302. One end of each of the two adjusting rods 9 passes through a locking hole 8 and the circular insertion hole of the internal bracket 7 and is inserted into the inner wall of the door body 1.

[0031] Specifically, the driving process of the gear 304 is as follows: the drive shaft 4 is driven by the drive motor to rotate, and the wheel 5 on the drive shaft 4 is driven by the belt 6 to rotate the wheel 5 on the shaft 305, so that the wheel 5 meshes with the chain 303 to make it rotate; the process of adjusting the side drive seat 301 and the side retaining seat 302 is as follows: pull out the adjusting rod 9 to remove the limit on the built-in card holder 7 on the side drive seat 301 and the side retaining seat 302, pull down the side drive seat 301 and the side retaining seat 302 to make the brush belt 307 move down as a whole, and then insert the adjusting rod 9 to limit the built-in card holder 7; the adjusting rod 9, the built-in card holder 7 and the carding hole 8 are used to facilitate the placement and storage of the side drive seat 301 and the side retaining seat 302.

[0032] Reference Figure 4 and Figure 5 The door body 1 has a side attachment groove 10, which is located on one side of the side attachment drive seat 301. A dust removal assembly 11 is installed inside the side attachment groove 10. The dust removal assembly 11 includes a dust removal plate 1101 and multiple dust scrapers 1102. The dust removal plate 1101 and the multiple dust scrapers 1102 are all connected by bolts. The dust removal plate 1101 is slidably connected to the side attachment groove 10. Two cylindrical holes are opened inside the side attachment groove 10. Slide rods 1103 are bolted to the inner walls of each cylindrical hole. Two circular holes are opened on the side of the dust removal plate 1101 near the side attachment groove 10. Each slide rod 1103 is slidably connected to the inner wall of the two circular holes of the dust removal plate 1101. Each slide rod 1103 is fitted with a storage spring 1104. The two ends of the storage spring 1104 are respectively connected to the inner wall of the side groove 10 and the outer wall of the dust removal plate 1101 by bolts. The dust removal plate 1101 has an installation groove on the side away from the side groove 10. The installation groove has a circular hole. The inside of the circular hole is rotatably connected to the positioning plate 1105 through a bearing. The side groove 10 has a positioning groove 1106 on one side. The positioning plate 1105 is located inside the positioning groove 1106.

[0033] Specifically, before the cleaning component 3 is put into operation, the locking plate 1105 is rotated to make it rotate out of the locking slot 1106. Under the elastic force of the storage spring 1104, the dust removal plate 1101 is moved out of the side slot 10. During the use of the cleaning component 3, when the soft brush 308 rotates, it will come into contact with the dust scraper 1102 on the dust removal plate 1101. The dust scraper 1102 scrapes off the dust and impurities adhering to the soft brush 308 to prevent them from adhering to the soft brush 308 and affecting the brushing effect of the soft brush 308.

[0034] In specific application scenarios, the dust removal component 11 is suitable for cleaning the soft brush 308 during the use of the cleaning component 3. That is, the dust scraper 1102 on the dust removal plate 1101 contacts the rotating soft brush 308 to scrape off the dust and impurities adhering to the soft brush 308, so as to avoid the soft brush 308 being affected by a lot of dust and impurities, thereby further improving the cleaning effect of the soft brush 308. The elasticity of the storage spring 1104 makes it easy to take out and store the dust removal plate 1101.

[0035] Reference Figure 2 and Figure 6 The door body 1 is provided with an adapter card seat 12 on its outside. The adapter card seat 12 is snapped into the door body 1. The adapter card seat 12 is connected to the motor 13 by bolts. The output end of the motor 13 is connected to the reduction box 14 by a coupling. The reduction box 14 is provided with a rotating shaft 15. The top of the rotating shaft 15 is provided with a hexagonal plug. The hexagonal plug is inserted into the hexagonal socket of the drive shaft rod 4.

[0036] Specifically, after the cleaning component 3 and the dust removal component 11 are taken out, the adapter card holder 12 is snapped into the frame of the door body 1 for fixation. The hexagonal pin at the top of the rotating shaft 15 is inserted into the hexagonal socket of the shaft rod. Then, the motor 13 is started to drive the rotating shaft 15 to rotate, and the rotating shaft 15 drives the drive shaft rod 4 to rotate.

[0037] Reference Figure 1 and Figure 7 The external side of the functional slot 2 is provided with a sealing plate 16, which is connected to the door body 1 by bolts, and the door body 1 is provided with tempered glass 17; the upper and lower sides of the two door bodies 1 are provided with track grooves, and the outer side of the two door bodies 1 is provided with the same door frame 18. The upper and lower inner walls of the door frame 18 are provided with two tracks, and the two door bodies 1 are slidably connected to the two tracks respectively.

[0038] Reference Figure 7 and Figure 8 Two loading and unloading components 19 are provided on the door frame 18, and the two loading and unloading components 19 are staggered. The loading and unloading components 19 include loading and unloading grooves 1901 and sealing plates 1902. The loading and unloading grooves 1901 are located on the door frame 18. Multiple equidistant recesses 1904 are provided on the loading and unloading grooves 1901. Each recess 1904 is provided with a top block 1905. A return spring 1906 is bolted between the top block 1905 and the bottom inner wall of the recess 1904. Multiple equidistant protrusions 1903 are provided on the lower side of the sealing plate 1902. The multiple protrusions 1903 are inserted into the multiple recesses 1904. Two symmetrical screw holes are provided on the sealing plate 1902. Screws 1907 are provided between the sealing plate 1902 and the door frame 18.

[0039] Specifically, before or after cleaning the sliding door track, remove screw 1907 and take out the sealing plate 1902 to facilitate the cleaning of dust and impurities accumulated inside the track.

[0040] In specific application scenarios, the loading and unloading assembly 19 is suitable for the processing stage after dust and impurities in the sliding door track are brushed off. That is, by using the loading and unloading assembly 19, dust and impurities can be processed from the gap in the loading and unloading groove 1901 after the sealing plate 1902 is removed, so as to remove the dust and impurities in the track groove and avoid the situation that the sliding door track groove is too deep and the internal dust and impurities cannot be completely removed.

[0041] It should be noted that the loading and unloading assembly 19 facilitates the installation and removal of the sliding door. The sealing plate 1902 is removed to install and remove the sliding door at the loading and unloading slot 1901, reducing the difficulty of installing the sliding door.

[0042] Working principle: During use, clean the sliding door track, open the function slot 2, pull out the brush belt 307 so that the short shafts on the two toothed discs 304 slide out from the driving shaft 305 and the fixing shaft 306 respectively. The chain 303, along with the brush belt 307, extends out from the function slot 2. Pull out the adjusting rod 9 to remove the limit on the built-in bracket 7 on the side drive seat 301 and the side fixing seat 302. Pull down the side drive seat 301 and the side fixing seat 302 so that the brush belt 307 moves down as a whole. Then insert the adjusting rod 9 to limit the built-in bracket 7. The soft brush 308 outside the brush belt 307 contacts the sliding door track. At the same time, rotate the locking plate 1105 to make it rotate out from the locking slot 1106. Under the elastic force of spring 1104, dust removal plate 1101 is moved out of side slot 10. Then, adapter card 12 is snapped into the frame of door body 1 for fixation. The hexagonal pin at the top of the rotating shaft 15 is inserted into the hexagonal hole of the shaft rod. The motor 13 is started to drive the rotating shaft 15 to rotate. The rotating shaft 15 drives the drive shaft rod 4 to rotate. The wheel 5 on the drive shaft rod 4 is driven by the belt 6 to drive the wheel 5 on the shaft rod 305 to rotate. Thus, the wheel 5 meshes with the chain 303 to make it rotate. The brush belt 307 rotates and the soft brush 308 brushes the inside of the track. During the brushing process, the door body 1 is moved slowly to achieve cleaning of different positions of the track. The dust and impurities after brushing are concentrated on one side of the track for further processing.

[0043] During the use of the cleaning component 3, when the soft brush 308 rotates, it will come into contact with the dust scraper 1102 on the dust removal plate 1101. The dust scraper 1102 scrapes off the dust and impurities adhering to the soft brush 308 to prevent them from adhering to the soft brush 308 and affecting the brushing effect of the soft brush 308.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
