Description

Technical Field

[0001] This utility model relates to the field of folding door technology, specifically a heat-insulated folding door. Background Technology

[0002] Folding doors are a common type of door. They utilize hinges or connecting devices to allow the door panels to fold and unfold along a specific track. When the door is open, the door panels fold up one by one and are stored to one or both sides along the track, taking up less space. When closed, the door panels unfold one by one, returning to the normal door state and achieving space partitioning.

[0003] There are many types of folding doors. Besides the simple folding function, heat insulation is gradually becoming an important reference indicator for users when choosing a folding door. Chinese Patent Publication No. CN 216617298 U discloses a heat-insulated folding door that prevents hand pinching. It includes a door frame, a groove in the folding door body, a shrink block slidably connected within the groove, a cavity in the shrink block, a guide rod slidably connected within the cavity, a spring mounted on the surface of the guide rod, and one end of the guide rod fixedly connected to the inner wall of the groove. In this utility model, when the folding door body is opened by the door handle, two sets of sponge pads are provided on the sides of the folding door body with grooves, and sliders are slidably connected inside the grooves.

[0004] In the aforementioned insulated folding door, adjacent door panels are connected by hinges, with the two middle door panels separated from each other. Pushing the middle two door panels allows multiple door panels to fold. However, only the two outermost door panels are connected to the door frame. When the door panels are pushed, the remaining door panels, lacking restraint, experience significant displacement under the pushing force. This prevents adjacent door panels from folding quickly, requiring manual restraint and increasing the difficulty of folding. Utility Model Content

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.

[0032] Please see Figure 1-8 In this embodiment of the utility model, a heat-insulating folding door includes multiple door panels 1, and the multiple door panels 1 are all located between two side door frames 2. The tops of the two side door frames 2 are respectively fixedly connected to the bottom ends of the upper door frame 5, and the bottoms of the two side door frames 2 are respectively fixedly connected to the top ends of the limiting profile plate 8.

[0033] Both sides of the multiple door panels 1 are fixedly connected with side profile plates 10, wherein the side profile plates 10 on one side of the two door panels 1 located on the side are rotatably connected to the inner side of the two side door frames 2 by hinges 9, and the side profile plates 10 on the other side are rotatably connected to the two supporting profile plates 11 by hinges 9.

[0034] Among the multiple door panels 1, the side profile plates 10 of the two middle door panels 1 located away from each other are rotatably connected to the two supporting profile plates 11 by hinges 9, and the side profile plates 10 of the two close to each other are rotatably connected to the two sliding profile plates 12 by hinges 9. The upper ends of the two sliding profile plates 12 are fixedly connected to roller assembly 4, and the bottoms are fixedly connected to the lower door frame 7. The bottom of the lower door frame 7 is fixedly connected to multiple roller assembly 6.

[0035] The upper ends of the multiple roller assemblies 4 are slidably connected to the upper door frame 5, and the lower ends of the multiple roller assemblies 6 are slidably connected to the limiting profile plate 8.

[0037] By adopting the above technical solution, multiple side door frames 2, upper door frame 5 and limiting profile plate 8 form a rectangular frame, which supports multiple door panels 1 and limits the movement distance and range of multiple door panels 1, ensuring that multiple door panels 1 can be easily folded and unfolded; the side profile plate 10 fixedly connected to both sides of multiple door panels 1 can increase the stability of door panels 1, and also increase the sturdiness of door panels 1.

[0038] In this embodiment, a connector 44 is fixedly connected to the top of the lead screw 42. Rollers 43 are rotatably connected to both sides of the connector 44. Both rollers 43 are located inside the upper door frame 5 and are slidably connected to the upper door frame 5.

[0039] The bottom of the lead screw 42 is coaxially fixedly connected to a connecting shaft 45, which is located below the connecting plate 41, and a spring 46 is sleeved on the outside of the connecting shaft 45; one end of the spring 46 is in contact with the connecting plate 41, and the other end is in contact with the cap at the bottom of the connecting shaft 45.

[0040] The roller assembly 2 6 includes a connecting plate 2 61, which is fixedly connected to the lower door frame 7; a connecting member 2 63 is fixedly connected to the bottom middle of the connecting plate 2 61, and rollers 2 62 are rotatably connected to both sides of the connecting member 2 63.

[0041] By adopting the above technical solution, when the door panel 1 is pushed, multiple rollers 43 move along the trajectory of the upper door frame 5, and multiple rollers 62 move along the trajectory of the profile plate body 81. While not affecting the normal movement of the door panel 1, the movement range of the door panel 1 can also be limited, allowing multiple door panels 1 to be quickly folded and unfolded, reducing the difficulty of using folding doors.

[0042] In this embodiment, the limiting profile plate 8 includes a profile plate body 81. Two guide protrusions 83 are symmetrically embedded on the top of the profile plate body 81. The two guide protrusions 83 correspond to the positions of the two rollers 62 respectively, and the arc-shaped protrusions on the top of the two guide protrusions 83 are respectively located in the groove between the two rollers 62.

[0044] By adopting the above technical solution, multiple sealing strips 82 in multiple side door frames 2, upper door frame 5, limiting profile plate 8, side profile plate 10, supporting profile plate 11 and sliding profile plate 12 play a sealing role, blocking the air flow on both sides of the door panel 1, thereby achieving the purpose of heat insulation.

[0045] The working principle of this utility model is as follows: multiple side door frames 2, upper door frame 5 and limiting profile plate 8 form a rectangular frame, which supports multiple door panels 1 and limits the movement distance and range of multiple door panels 1, ensuring that multiple door panels 1 can be easily folded and unfolded; the side profile plate 10 fixedly connected to both sides of multiple door panels 1 can increase the stability of door panels 1 and also increase the sturdiness of door panels 1.

[0046] When the door panel 1 is pushed, multiple rollers 43 move along the trajectory of the upper door frame 5, and multiple rollers 62 move along the trajectory of the profile plate body 81. While not affecting the normal movement of the door panel 1, the movement range of the door panel 1 can be limited, allowing multiple door panels 1 to be quickly folded and unfolded, reducing the difficulty of using the folding door.

[0047] Multiple sealing strips 82 in the multiple side door frames 2, upper door frame 5, limiting profile plate 8, side profile plate 10, supporting profile plate 11 and sliding profile plate 12 play a sealing role, blocking the air flow on both sides of the door panel 1, thereby achieving the purpose of heat insulation.
