Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, specifically a retractable and foldable customized sliding door. Background Technology

[0002] Sliding doors are a common type of door in homes, referring to doors that can be pushed and pulled. With the development of technology and the diversification of decoration methods, sliding doors have evolved from traditional panel surfaces to glass, fabric, rattan, and aluminum alloy profiles. From sliding doors and folding doors to partition doors, the functions and scope of use of sliding doors are constantly expanding.

[0003] For example, the national authorized patent announcement number CN217481092U discloses an aluminum alloy folding sliding door, including a hanging rail. Several hanging clamps are slidably connected to the lower side of the hanging rail, and pins are fixedly connected to the lower side of the hanging clamps. The pins are rotatably embedded in the upper middle part of different connecting plates. Side plates are fixed to both ends of the connecting plates with screws, and cylinders are fixedly connected to the outer side of the side plates. This utility model provides an aluminum alloy folding sliding door. As the hanging clamps move along the hanging rail, the folding units can be pulled and moved, so that the angle of adjacent folding units can gradually change, allowing the sliding door to be folded or unfolded. In the unfolded state, multiple folding units are flush with each other, providing a large protective area. In the folded state, multiple folding units are parallel and close together, greatly saving storage space. It is especially suitable for use in wide door openings. Moreover, the hanging rail is a custom track, which can meet the needs of corner installation. The hanging rail design eliminates the need to install tracks on the ground, making it easy to clean and aesthetically pleasing and practical.

[0004] However, the aforementioned aluminum alloy folding sliding doors rely more on the straight sliding of the hanging clamps along the hanging rail, and achieve overall opening and closing by changing the angle of adjacent folding units. However, their extension range is completely limited by the length of the hanging rail and the number of folding units. When the width of the doorway needs to be adjusted temporarily, such as when moving extra-wide items, the door panel length cannot be further extended or retracted, resulting in low adaptability. Utility Model Content

[0005] The purpose of this utility model is to provide a retractable and foldable custom sliding door to solve the problem mentioned in the background art that aluminum alloy folding sliding doors are limited by the length of the hanging rail and the number of folding units, and cannot flexibly extend or retract the door panel length when the door opening width needs to be adjusted temporarily, thus resulting in low adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A retractable and foldable custom sliding door includes: a door frame, one end of which extends to form a frame opening, and two ends of which are rotatably mounted with first door panels. Two sets of first door panels are rotatably mounted with second door panels at their inner ends, so that the first and second door panels can be mutually shielded by their rotatable connection to open the frame opening. Both the first and second door panels are rotatably mounted with telescopic mechanisms.

[0008] Preferably, guide wheels are rotatably mounted on both the upper and lower surfaces of the second door panel, and the guide wheels roll in guide grooves, which are embedded in the upper and lower surfaces of the frame opening.

[0009] Preferably, the first door panel and the second door panel are fixedly connected together by four telescopic rods, and one end of the second door panel has an embedded groove.

[0010] Preferably, the telescopic mechanism includes two sets of first connecting arms and two sets of second connecting arms; the two sets of first connecting arms and the two sets of second connecting arms are arranged vertically opposite each other and are rotatably mounted on the inner ends of the first door panel and the second door panel respectively; a U-shaped frame is rotatably connected between the ends of the two sets of first connecting arms away from the first door panel and the ends of the two sets of second connecting arms away from the first door panel and the second door panel; the telescopic and extension movements of the first door panel and the second door panel are realized through the coordinated action of the four telescopic rods and the hinged first and second connecting arms.

[0011] Preferably, a self-locking electric push rod is fixedly connected between each pair of vertically opposite U-shaped frames, so that the self-locking electric push rod can push the first connecting arm and the second connecting arm by pushing and pulling the piston rod.

[0012] Preferably, both the first and second door panels have PVC flexible boards fixedly connected in a zigzag shape. The PVC flexible boards are also fitted onto the outer surface of the two sets of four-section telescopic rods in each set of door panels, which can be supported to maintain a vertical shape and prevent them from collapsing inward when folded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the cooperation of the door frame, frame opening, guide rail groove, and guide rail wheels, it achieves smooth sliding and precise guidance of the door panel, ensuring a smooth opening and closing process. Furthermore, through the hinged structure of the first and second door panels and the four-section telescopic rod, combined with the linkage of the connecting arm, self-locking electric push rod, and U-shaped frame in the telescopic mechanism, it can flexibly realize the folding and storage of the door panel and the extension and contraction of its width. This not only greatly reduces the space occupied when folding, but also allows for adjustment of the passage size according to passage needs, adapting to diverse scenarios. At the same time, the PVC soft board effectively prevents the door panel from collapsing, ensuring structural stability. Overall, it improves the ease of operation, space utilization, and safety of use, combining practicality and flexibility. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] like Figures 1-2As shown, a retractable and foldable custom sliding door includes: a door frame 1, with a frame opening 101 extending from one end of the door frame 1. First door panels 103 are rotatably mounted at both ends of the frame opening 101. Second door panels 104 are rotatably mounted at one end of the inner side of each of the two sets of first door panels 103, allowing the first door panels 103 and second door panels 104 to mutually cover each other through their rotatable connection points, thus enabling the frame opening 101 to be unfolded. Telescopic mechanisms 2 are rotatably mounted on both the first door panels 103 and second door panels 104. Guide wheels 105 are rotatably mounted on the upper and lower surfaces of the second door panel 104, rolling within guide grooves 102, which are embedded in the upper and lower surfaces of the frame opening 101. The first door panels 103 and second door panels 104 are fixedly connected together by four telescopic rods 107, and a pull groove 106 is embedded in one end of the second door panel 104.

[0022] Through the design of the door frame 1, frame opening 101, guide rail groove 102, first door panel 103, second door panel 104, guide rail wheel 105, four-section telescopic rod 107, and telescopic mechanism 2, when the frame opening 101 needs to be closed, the two sets of first door panels 103 rotate inward from their initial rotation positions at both ends of the frame opening 101, simultaneously driving the second door panel 104, which is hinged to them, to move synchronously. At this time, the guide rail wheels 105 on the upper and lower surfaces of the second door panel 104 roll along the guide rail groove 102 on the upper and lower surfaces of the frame opening 101 towards the center of the frame opening 101. The first door panel 103 and the second door panel 104 rotate, allowing them to gradually approach each other through the rotating connection and form a barrier. The four-section telescopic rod 107 remains extended during the rotation of the door panel, ensuring the connection stability between the first door panel 103 and the second door panel 104. When the free ends of the two sets of second door panels 104 are connected, the first door panel 103 and the second door panel 104 can form a complete plane together, completely covering the frame opening 101 and realizing the sealing function.

[0023] If it is necessary to open the frame opening 101 and fold the door panel, a pulling force can be applied through the pull groove 106 at one end of the second door panel 104. At this time, under the action of the pulling force, the second door panel 104 drives the guide wheel 105 to slide along the guide groove 102 towards both ends of the frame opening 101. At the same time, the rotation connection between the first door panel 103 and the second door panel 104 begins to rotate in the opposite direction. As the sliding and rotation continue, the two sets of first door panels 103 can rotate and retract towards the inner side of both ends of the frame opening 101, and the second door panel 104 moves closer to the first door panel 103 and finally fits together, so that the entire door panel is folded and stored on both sides of the frame opening 101, greatly reducing the space occupied.

[0024] When it is necessary to reduce the width of the first door panel 103 and the second door panel 104, the telescopic mechanism 2 can be activated to pull the four telescopic rods 107 together to gradually retract, thereby shortening the width of the first door panel 103 and the second door panel 104. This increases the passage width of the frame opening 101, allowing for different passage requirements, such as when moving wider items without fully opening the frame opening 101, or when temporarily widening the activity area in a narrow space. By reducing the door panel width, a more suitable passage size can be obtained, avoiding space waste or passage obstruction caused by a fixed door panel width, and making the use of the door more in line with the dynamic changes of the actual scene.

[0025] like Figures 3-4 As shown, the telescopic mechanism 2 includes two sets of first connecting arms 201 and two sets of second connecting arms 202. The two sets of first connecting arms 201 and two sets of second connecting arms 202 are arranged vertically opposite each other and are rotatably mounted on the inner ends of the first door panel 103 and the second door panel 104, respectively. A U-shaped frame 204 is rotatably connected between the ends of the two sets of first connecting arms 201 away from the first door panel 103 and the second door panel 104 and the ends of the two sets of second connecting arms 202 away from the first door panel 103 and the second door panel 104. Through the coordinated action of the four telescopic rods 107 and the hinged first connecting arms 201 and the second connecting arms 202, the telescopic and extension actions of the first door panel 103 and the second door panel 104 are realized. A self-locking electric push rod 203 is fixedly connected between each pair of vertically opposite U-shaped frames 204, so that the self-locking electric push rod 203 can push the first connecting arms 201 and the second connecting arms 202 through the pushing and pulling of the piston rod. The first door panel 103 and the second door panel 104 are both fixedly connected to PVC soft boards 205 in a curved shape. The PVC soft boards 205 are also fitted onto the outer surface of the two sets of four-section telescopic rods 107 in each door panel, which can be supported to maintain a vertical shape and prevent them from collapsing inward when folded.

[0026] Through the design of the first connecting arm 201, the second connecting arm 202, the self-locking electric push rod 203, the U-shaped frame 204 and the PVC soft board 205, when the width of the first door panel 103 or the second door panel 104 is extended, the self-locking electric push rod 203 can be activated to push the piston rod outward, pushing the U-shaped frame 204 fixedly connected to it to move vertically outward. The U-shaped frame 204 can then drive the first connecting arm 201 and the second connecting arm 202 rotatably connected to it to rotate. Since the two sets of first connecting arms 201 and second connecting arms 202 are rotatably installed on both sides of the first door panel 103 and the second door panel 104 respectively in a vertically opposite position, their rotation will push the first door panel 103 or the second door panel 104 to be pushed open. During the opening process, they will also extend together through the internal four-section telescopic rod 107 to realize the extension of the door panel.

[0027] When it is necessary to reduce the width of the first door panel 103 or the second door panel 104, the piston rod of the self-locking electric push rod 203 retracts, causing it to pull the U-shaped frame 204 to move vertically inward. This, in turn, causes the first connecting arm 201 and the second connecting arm 202 to rotate in opposite directions, causing the first door panel 103 or the second door panel 104 to reduce the width of the door panel through the retraction of the four-section telescopic rod 107. During this process, the PVC soft board 205, which is fixedly connected in a zigzag shape inside the first door panel 103 and the second door panel 104, is fitted on the outer surface of the four-section telescopic rod 107 and is kept vertical by the movement of the telescopic rod and the connecting arm. This effectively prevents the door panel from collapsing inward when folding or extending, ensuring the stability of the door panel shape and making the entire extension and retraction process smooth and reliable.

[0028] Based on the above technical solution, the working steps of this solution are summarized as follows: When the frame opening 101 needs to be closed, the two sets of first door panels 103 rotate inward from their initial rotation positions at both ends of the frame opening 101, simultaneously driving the second door panel 104 hinged to them to move synchronously. At this time, the guide wheels 105 on the upper and lower surfaces of the second door panel 104 roll along the guide grooves 102 on the upper and lower surfaces of the frame opening 101 toward the center of the frame opening 101, providing guidance for the movement of the door panel. As the first door panel 103 and the second door panel 104 rotate, they gradually approach each other through the rotation connection and form a barrier. The four-section telescopic rod 107 remains extended during the rotation of the door panel, ensuring the connection stability between the first door panel 103 and the second door panel 104. When the free ends of the second door panel 104 are aligned, the first door panel 103 and the second door panel 104 together form a complete plane, completely covering the frame opening 101 to achieve a sealing function. If it is necessary to open the frame opening 101 and fold the door panel, a pulling force can be applied through the pull groove 106 at one end of the second door panel 104. At this time, under the action of the pulling force, the second door panel 104 drives the guide wheel 105 to slide along the guide groove 102 towards both ends of the frame opening 101. At the same time, the rotational connection between the first door panel 103 and the second door panel 104 begins to rotate in the opposite direction. As the sliding and rotation continue, the two sets of first door panels 103 can rotate and retract towards the inner side of both ends of the frame opening 101, and the second door panel 104 moves closer to the first door panel 103 and finally fits together, thereby making the entire frame opening 101 close together. The main door panel is folded and stored on both sides of the frame opening 101. When it is necessary to extend the width of the first door panel 103 or the second door panel 104, the self-locking electric push rod 203 can be activated to push the piston rod outward, pushing the U-shaped frame 204 fixedly connected to it to move vertically outward. The U-shaped frame 204 can then drive the first connecting arm 201 and the second connecting arm 202 rotatably connected to it to rotate. Since the two sets of first connecting arms 201 and second connecting arms 202 are rotatably installed on both sides of the first door panel 103 and the second door panel 104 respectively in a vertically opposite position, their rotation will push the first door panel 103 or the second door panel 104 to unfold. During the unfolding process, they will also extend together through the internal four-section telescopic rod 107 to realize the door panel... The extension of the door panel 103 and the second door panel 104 is such that when the width of the first door panel 103 or the second door panel 104 needs to be reduced, the piston rod of the self-locking electric push rod 203 retracts, causing the U-shaped frame 204 to move vertically inward. This, in turn, causes the first connecting arm 201 and the second connecting arm 202 to rotate in opposite directions, causing the first door panel 103 or the second door panel 104 to reduce the width of the door panel through the retraction of the four-section telescopic rod 107. During this process, the PVC soft board 205, which is fixedly connected in a zigzag shape inside the first door panel 103 and the second door panel 104, is kept vertical by the movement of the telescopic rod and the connecting arm because it is fitted on the outer surface of the four-section telescopic rod 107. This effectively prevents the door panel from collapsing inward when folding or extending, ensuring the stability of the door panel shape.

[0029] In summary, by utilizing the telescopic function of the door panel, it can meet different passage requirements, such as when moving wider items without fully opening the frame 101, or when temporarily widening the activity area in a narrow space. By reducing the width of the door panel, a more suitable passage size can be obtained, avoiding space waste or passage obstruction caused by a fixed door panel width, and making the use of the door more in line with the dynamic changes of the actual scene.
