Description

Technical Field

[0001] This utility model relates to the field of folding doors, specifically to a limiting mechanism for folding doors. Background Technology

[0002] A folding door is a type of door that can be flexibly folded. It mainly consists of a door frame, door panels, transmission components, swivel arm components, transmission rods, and directional devices. Multiple door panels connected by hinges open in a folding manner, offering many unique features and advantages.

[0003] The limiting mechanism of a folding door is a crucial component that ensures the door stops accurately at a predetermined position during opening and closing. The limiting mechanism physically or mechanically restricts the range of motion of the folding door, preventing over-opening or over-closing, thus protecting the door and its related components from damage and ensuring the door's safety and stability. However, existing folding doors can only be fixed when fully open or closed, and cannot be stopped at other angles. Users cannot customize the stopping position according to their habits and needs, reducing user comfort and experience. Utility Model Content

[0004] To address the technical problem that existing folding doors can only be fixed when fully open and closed, and cannot be stopped at other angles, thus reducing user comfort and experience by preventing users from setting the stopping position of the folding door according to their usage habits and needs, this utility model provides a limiting mechanism for folding doors.

[0005] The technical solution adopted by this utility model is as follows: it includes two sets of slide rails, which are arranged vertically. A connecting column is fixedly installed between the two sets of slide rails. Each slide rail has a slide groove, and several sets of slide seats are slidably connected in each slide groove. A door leaf is rotatably installed between the two sets of vertically opposite slide seats. Adjacent door leaves are rotatably connected by hinges. Each set of vertically opposite slide seats has a through groove, and two sets of limiting blocks are slidably installed in the through groove. A locking head is fixedly installed on one side of each of the two sets of limiting blocks. Several sets of locking slots are opened on both sides of the slide groove. The locking slots are adapted to the locking heads. A toothed plate is fixedly installed at one end of each limiting block. A gear is meshed on one side of the toothed plate, and the gear is rotatably installed in the through groove.

[0006] Furthermore, a sliding column is fixedly installed between two sets of upper and lower opposing sliding blocks. The sliding column is rotatably connected to one set of the door panels. A handle is provided on the outside of the sliding column. A rotating shaft is fixedly installed at one end of the handle. The rotating shaft is rotatably connected to the sliding column. A first bevel gear is fixedly connected to one end of the rotating shaft. Second bevel gears mesh on both sides of the first bevel gear. A rotating rod is fixedly installed on the end face of the second bevel gear. One end of the rotating rod is fixedly connected to the gear.

[0007] By adopting the above technical solution, the throttle can drive the gear to rotate.

[0008] Furthermore, the slide block is provided with a guide groove, and a guide block is slidably installed in the guide groove. The guide block is fixedly connected to the bottom of the limiting block.

[0009] By adopting the above technical solution, the stability of the limit block during movement is improved.

[0010] Furthermore, a connecting shaft is rotatably installed between the slide and the door leaf. Both the slide and the door leaf are provided with round head grooves, and anti-detachment heads are rotatably installed in the round head grooves. The anti-detachment heads are fixedly connected to both ends of the connecting shaft.

[0011] By adopting the above technical solutions, the stability of the door leaf after installation can be improved.

[0012] Furthermore, a storage groove is provided on one side of the connecting column, and a positioning groove is provided in the storage groove. A buffer plate is provided on one side of the sliding column, and the buffer plate is adapted to the positioning groove.

[0013] By adopting the above technical solutions, the noise generated when the door is fully closed can be reduced.

[0014] Furthermore, a telescopic damping rod is fixedly installed on one side of the sliding column, one end of the telescopic damping rod is fixedly connected to the rotating shaft, and a spring is fixedly installed between the buffer plate and the sliding column, with the spring sleeved on the outside of the telescopic damping rod.

[0015] By adopting the above technical solution, the vibration generated when the door is fully closed can be reduced.

[0016] The beneficial effects of this utility model are: by using a throttle handle in conjunction with a rotating shaft, a first bevel gear, a second bevel gear, and a rotating rod, the gear is driven to rotate. The gear, in conjunction with a toothed plate, drives two sets of limiting blocks in the slide to move relative to each other. The limiting blocks, in conjunction with a locking head and a locking groove, can limit the slide that slides in the groove, thereby fixing the door leaf at a suitable angle. This allows the door leaf to be positioned according to the user's habits and needs, improving the flexibility and comfort of the folding door used by the user.

[0017] By creating a storage slot on one side of the connecting column, the sliding column is hidden within the connecting column when the door is fully closed, improving the overall aesthetics of the folding door. The sliding column, together with the telescopic damping rod, spring, and buffer plate, can reduce the vibration and impact on the door when it is closed, thus protecting the door and improving the stability and safety of the folding door.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0028] To address the problems existing in the background art, this application proposes the following technical solution: It includes two sets of slide rails 1, arranged vertically, with a connecting column 2 fixedly installed between the two sets of slide rails 1. Each slide rail 1 has a slide groove 3, and several sets of slide blocks 4 are slidably connected in each slide groove 3. Door leaves 5 are rotatably installed between the two sets of vertically opposite slide blocks 4, and adjacent door leaves 5 are rotatably connected by hinges 6. Each set of vertically opposite slide blocks 4 has a through groove 8, and two sets of limiting blocks 9 are slidably installed in the through groove 8. A locking head 10 is fixedly installed on one side of each of the two sets of limiting blocks 9. Several sets of locking slots 11 are opened on both sides of the slide groove 3, and the locking slots 11 are adapted to the locking heads 10. A toothed plate 13 is fixedly installed at one end of the limiting block 9, and a gear 12 meshes with one side of the toothed plate 13. The gear 12 is rotatably installed in the through groove 8.

[0029] Several sets of door panels 5 are movably installed between two sets of slide rails 1. One end of the door panel 5 is rotatably installed on one side of the connecting column 2. Pulling the other end of the door panel 5 causes the adjacent door panels 5 to move, opening or closing the folding door. After the door panel 5 is moved to a suitable angle and position, the gear 12 pushes the two sets of toothed plates 13 to move away from each other. The toothed plates 13 drive the limit block 9 and the locking head 10 to move. The locking head 10 is inserted into the corresponding slot 11. The locking head 10, together with the slot 11, restricts the movement of the limit block 9. The limit block 9, together with the through groove 8, restricts the movement of the slide block 4, thereby fixing the door panel 5 on the slide rail 1, keeping the door panel 5 at its own angle, and keeping it in the position that the user is accustomed to and needs, improving the user's comfort and experience.

[0030] To further explain, a sliding column 7 is fixedly installed between two sets of upper and lower opposing sliding blocks 4. The sliding column 7 is rotatably connected to a set of door leaves 5. A handle 15 is provided on the outside of the sliding column 7. A rotating shaft 16 is fixedly installed at one end of the handle 15. The rotating shaft 16 is rotatably connected to the sliding column 7. A first bevel gear 17 is fixedly connected to one end of the rotating shaft 16. A second bevel gear 18 is meshed on both sides of the first bevel gear 17. A rotating rod 14 is fixedly installed on the end face of the second bevel gear 18. One end of the rotating rod 14 is fixedly connected to the gear 12.

[0031] After the door leaf 5 is positioned correctly, the user manually turns the handle 15. The handle 15 drives the shaft 16 and the first bevel gear 17 to rotate. The first bevel gear 17 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the gear 12 to rotate through the rotating rod 14. The gear 12 pushes the locking head 10 into the slot 11, thus limiting the door leaf 5 and positioning it correctly on the slide rail 1. When it is necessary to adjust the angle of the door leaf 5, the handle 15 is reversed to remove the locking head 10 from the slot 11, releasing the limitation on the door leaf 5. The door leaf 5 can then move freely to adjust its position, improving the ease of use of the limiting mechanism.

[0032] Furthermore, the slide block 4 has a guide groove 19, and a guide block 20 is slidably installed in the guide groove 19. The guide block 20 is fixedly connected to the bottom of the limit block 9.

[0033] The guide block 20, together with the guide groove 19, guides and limits the movement of the limit block 9, preventing the limit block 9 from deviating during movement, improving the smoothness and stability of the limit mechanism during use, and enhancing the user experience.

[0034] Furthermore, a connecting shaft 21 is rotatably installed between the slide 4 and the door leaf 5. Both the slide 4 and the door leaf 5 are provided with round head grooves 22. Anti-detachment heads 23 are rotatably installed in the round head grooves 22 and are fixedly connected to both ends of the connecting shaft 21.

[0035] The sliding block 4 and the door leaf 5 are rotatably connected by the connecting shaft 21. The anti-detachment head 23, together with the round head groove 22, plays a limiting role in the connecting shaft 21, preventing the sliding block 4 and the door leaf 5 from separating, improving the stability of the door leaf 5 after installation, and thus improving the safety of the folding door during use.

[0036] Furthermore, a storage groove 24 is provided on one side of the connecting column 2, and a positioning groove 28 is provided in the storage groove 24. A buffer plate 26 is provided on one side of the sliding column 7, and the buffer plate 26 is adapted to the positioning groove 28.

[0037] When the door leaf 5 is fully closed, the sliding column 7 moves into the storage groove 24 for concealment, improving the overall aesthetics of the folding door. At the same time, the buffer plate 26 contacts the positioning groove 28 to buffer the impact force when the sliding column 7 collides with the connecting column 2, thus protecting the door leaf 5 and improving the practicality of the folding door.

[0038] Furthermore, a telescopic damping rod 25 is fixedly installed on one side of the sliding column 7. One end of the telescopic damping rod 25 is fixedly connected to the rotating shaft 16. A spring 27 is fixedly installed between the buffer plate 26 and the sliding column 7. The spring 27 is sleeved on the outside of the telescopic damping rod 25.

[0039] When the door leaf 5 is fully closed, the positioning groove 28 contacts and presses against the buffer plate 26, causing the buffer plate 26 to move towards the slide column 7. The buffer plate 26 compresses and deforms the spring 27. The spring 27 absorbs and disperses the impact force when the buffer plate 26 collides with the positioning groove 28 through elastic deformation. The telescopic damping rod 25 prevents the spring 27 from rebounding and consumes the energy previously stored in the spring 27. By working with the spring 27, the telescopic damping rod 25 reduces the vibration and impact on the slide column 7, improves the stability and safety of the door leaf 5 when closed, and reduces the noise when closing the door leaf 5.

[0040] For specific operation, please refer to the following instructions: Push and pull the sliding column 7 to move it between the two sets of slide rails 1. The sliding column 7 drives several sets of door panels 5 to move, opening or closing them. After the door panel 5 is stopped in a suitable position on the slide rail 1 according to the user's usage habits, turn the handle 15 by hand. The handle 15 drives the rotating shaft 16 and the first bevel gear 17 to rotate. The first bevel gear 17 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the gear 12 to rotate through the rotating rod 14. The gear 12 drives the two sets of toothed plates 13 to move away from each other. The toothed plates 13 drive the limiting block 9 to move, so that the locking head 10 is inserted into the slot 11, completing the limiting of the sliding block 4 and fixing the door panel 5 on the slide rail 1. When it is necessary to adjust the position of the door panel 5, reverse the handle 15 to remove the locking head 10 from the slot 11. The door panel 5 can then move freely to adjust its position on the slide rail 1.
