DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] The present invention is described in detail with reference to the accompanying drawings.

[0024] like Figure 1-2 As shown, the present invention provides an overlapping telescopic door in a specific implementation, including a door panel outer frame 1 and a plurality of overlapping door panels 2, a door panel retracting device is arranged on the door panel outer frame 1, and the door panel retracting device includes a driving mechanism 3, a rotating roller 4 and a lifting belt 5, the driving mechanism 3 is used to be connected to the end of the rotating roller 4 to drive the rotating roller 4 to rotate, the top end of the lifting belt 5 is wound and fixed on the rotating roller 4, and the bottom end thereof is used to be connected to the bottom of the door panel 2 at the bottom;

[0025] like Figure 6 , Figure 8 As shown, an anti-separation component 7 is provided between two adjacent door panels 2 and the two adjacent door panels 2 can be engaged with each other to limit the position of the door panels 2 during their descent.

[0026] Embodiment 1:

[0027] like Fig. 9 As shown, when the rolling door needs to be rolled up, the driving mechanism 3, that is, the driving motor, is started. The driving motor drives the rotating roller 4 to rotate clockwise. The rotating roller 4 rotates clockwise to roll up the lifting belt 5, and the lifting belt 5 drives the bottom door panel to be lifted. When the bottom door panel is lifted to the level of the second to last door panel, the second to last door panel starts to be lifted, and so on, multiple door panels are lifted upward, and the door panels are pulled up to realize the rolling process.

[0028] like Figure 1 As shown, when the rolling door needs to be lowered, the driving mechanism, that is, the driving motor, is started. The driving motor drives the rotating roller 4 to rotate counterclockwise. The rotating roller 4 rotates counterclockwise to lower the lifting belt 5. The lifting belt 5 drives the door panel to move downward, thereby realizing the unfolding of the door panel.

[0029] Since an anti-separation component 7 is provided between two adjacent door panels 2, and the anti-separation component is a steel wire rope for connecting two adjacent door panels, the normal operation of the door panels in the retracted or unfolded state is ensured, and separation of multiple door panels during use is avoided.

[0030] Embodiment 2:

[0031] like Figure 3-5As shown, a first limiting snap-fitting component 8 is provided at the top end of the door panel 2, and a second limiting snap-fitting component 9 is provided at the bottom end thereof, a first limiting snap-fitting groove 10 inclined downward is provided on the inner side of the first limiting snap-fitting component 8, and its outer side extends outward to form a fixing plate 11, and a second limiting snap-fitting groove 12 inclined upward is provided on the outer side of the second limiting snap-fitting component 9, and two adjacent door panels 2 are mutually engaged through the first limiting snap-fitting groove 10 and the second limiting snap-fitting groove 12 to achieve limitation during the descent process.

[0032] During the use of the retractable door of the present invention, since the inner side of the first limiting engaging component 8 is provided with a first limiting engaging groove 10 inclined downward, and the outer side of the second limiting engaging component 9 is provided with a second limiting engaging groove 12 inclined upward, the two adjacent door panels 2 are engaged with each other through the first limiting engaging groove 10 and the second limiting engaging groove 12 to achieve limitation during the descent process.

[0033] When the rolling door is rolled up and folded, the door panel moves upward, and the second limit engaging groove 12 on the lower door panel moves upward, and in the process of upward movement, it is freed from the restraint of the first limit engaging groove 10 at the bottom end of the upper door panel, thereby realizing the folding of the door panel.

[0034] When the retractable door is unfolded, the door panel moves downward. When two adjacent door panels are unfolded to the maximum distance, the first limit engaging groove 10 on the upper door panel engages with the second limit engaging groove 12 on the lower door panel to limit the position. At this time, the door panel no longer moves.

[0035] like Figure 8 As shown, in order to facilitate the snap-fitting and fixing of the first limit snap-fitting groove 10 and the second limit snap-fitting groove 12, a first circular snap-fitting protrusion 16 is provided at the lower portion of the top end of the first snap-fitting groove 10, and a second circular snap-fitting protrusion 6 is provided at the upper portion of the bottom end of the second limit snap-fitting groove 12. The first circular snap-fitting protrusion 16 and the second circular snap-fitting protrusion 6 are snap-fitted and fixed to increase the stability of the snap-fitting and fixing between the two adjacent groups of door panels.

[0036] As a further elaboration of the present invention, the anti-separation component 7 is a steel wire rope, the top end of which is fixedly connected to the fixed plate 11 of the upper door panel 2, and the bottom end of which is fixedly connected to the fixed plate 11 of the lower door panel 2 in an adjacent position, so as to prevent the door panels from separating during the retracting process.

[0037] In order to facilitate the connection between the door panel and the first position-limiting engaging component, a first fixing engaging groove 13 is provided on the first position-limiting engaging component 8 for fixing and engaging with the top end of the door panel 2 .

[0038] In order to facilitate the connection between the door panel and the second position-limiting engaging component, a second fixing engaging groove 14 is provided on the second position-limiting engaging component 9 for fixing and engaging with the bottom end of the door panel 12 .

[0039] In order to facilitate the installation of the door panel, door panel running tracks 15 are set on both sides of the door panel outer frame 1, the two ends of the door panel 2 are set in the door panel running tracks 15, and the bottom end of the lifting belt 5 passes through the door panel running track 15 and the bottom of the door panel 2 at the bottom.

[0040] In order to facilitate folding and rolling up of the door panels, the plurality of door panels 2 are staggered and arranged, and their side edges are arranged in an inclined straight line in the open state.

[0041] As a further explanation of the present invention, the driving mechanism 3 is a driving motor.

[0042] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
