The lightweight all-aluminum folding door can effectively save space through its unique folding design, meeting the requirements of modern architecture for the efficient utilization of space;
[0003] However, the existing folding doors lack firm fixation in different states of folding and unfolding, and it is difficult to have better stability while ensuring the original flexibility. For example, it is impossible to well hold the folded and opened folding door in a fixed state to avoid displacement to facilitate user access. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defect that the existing folding doors lack firm fixation in different states of folding and unfolding, and it is difficult to have better stability while ensuring the original flexibility. For example, it is impossible to well hold the folded and opened folding door in a fixed state to avoid displacement to facilitate user access, and a lightweight all-aluminum folding door is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A lightweight all-aluminum folding door, including a folding door, the folding door includes a door frame and a first door and a second door located inside the door frame. The first door and the second door are connected by hinges. The top inner wall and the bottom inner wall of the door frame are both fixedly provided with slide rails. The top and the bottom of the second door and on the side far from the first door are both fixedly provided with second shafts. The outer wall of the second shaft is rotatably sleeved with second blocks, and the two second blocks are respectively fixedly arranged at one ends of the two slide rails. The top and the bottom of the first door and on the side far from the second door are both fixedly provided with first shafts. The outer wall of the first shaft is rotatably sleeved with first blocks, and the two first blocks are respectively slidably arranged inside the two slide rails;
[0007] A fixing component for fixing the first door, the fixing component is arranged inside the first door. The fixing component includes a plug rod. A sliding cavity is opened inside the first door, and the plug rod is slidably arranged inside the sliding cavity. A clamping groove is opened on the top of the slide rail located below and on the side close to the first shaft. The bottom end of the plug rod slidably penetrates through the first shaft and extends into the clamping groove.
[0008] In a possible design, a through hole is provided on one side of the first door, and the through hole communicates with the top end of the sliding cavity. Pressing plates are slidably arranged at both ends of the inner wall of the through hole. The same V-shaped rod is fixedly arranged between the two pressing plates.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Example 1
[0028] Reference Figure 1 A lightweight, all-aluminum folding door, used in the door and window industry, comprises the following: The folding door section: The door frame 1 is made of lightweight, all-aluminum material, providing sufficient strength and light weight. Slide rails 4 are fixed to the top and bottom inner walls of the door frame 1 to guide the sliding and folding of the door.
[0029] Reference Figure 4 Door No. 1 2 and Door No. 2 3: Both are made of lightweight all-aluminum material and are connected by hinges, allowing them to be folded and unfolded. Door No. 1 2 has shaft No. 1 11 at the top and bottom, and these shafts have rotating outer walls with blocks No. 12, which slide inside the slide rail 4 to achieve the door's sliding function. Door No. 2 has shaft No. 2 9 at the top and bottom, and shaft No. 2 has block No. 10 rotating outer walls. Block No. 10 is fixed to one end of the slide rail 4, allowing door No. 2 to rotate around this point.
[0030] Example 2
[0031] refer to Figure 5 , improved on the basis of Example 1: fixed component part:
[0032] Insertion rod 21 and sliding cavity 27: The sliding cavity 27 is provided inside the first door 2, and the insertion rod 21 is slidably arranged therein. The bottom end of the insertion rod 21 passes through the first shaft 11 and extends into the slot 5 at the top of the lower slide rail 4 to fix the door.
[0033] V-shaped rod 14 and pressure plate 7: A through hole 13 is defined on the side of door 2, connecting to the top of the slide cavity 27. Two pressure plates 7 are positioned within through hole 13, connected by a V-shaped rod 14. The V-shaped rod 14 extends through an opening 20 in the insertion rod 21. A connecting shaft 15 is positioned within the inner wall of the opening 20, and a cylinder 19 is rotatably mounted on the outer wall of the connecting shaft 15. Cylinder 19 is positioned above the V-shaped rod 14. By pushing the pressure plate 7, cylinder 19 is pressed against the V-shaped rod 14, causing it to rise.
[0034] Specifically, when the folding door needs to be folded or unfolded, the pressure plate 7 is pressed, and the pressure plate 7 drives the V-shaped rod 14 to move. The V-shaped rod 14 pushes the upper cylinder 19 upward, and the cylinder 19 drives the insertion rod 21 upward, so that the bottom end of the insertion rod 21 is disengaged from the inside of the card slot 5 to release it. At this time, the folding door can be folded or unfolded, thereby preventing the door from being displaced during daily use and ensuring that the door can maintain its position in two different states in a stable manner.
[0035] Reference Figure 6 Semi-circular block 17 and rotating plate 16: Door No. 1 2 also has an inner cavity 23 located above through-hole 13. Semi-circular block 17 is placed within cavity 23 and connected to connecting rod 18 via rotating plate 16 in two side grooves 22, enabling up and down movement of semi-circular block 17. The top end of insertion rod 21 slides through cavity 23. When rotating plate 16 causes semi-circular block 17 to rotate downward, thereby contacting insertion rod 21, preventing it from moving upward.
[0036] Specifically, when the door is fixed, by rotating the rotating plate 16, the rotating plate 16 drives the connecting rod 18 to rotate, and the connecting rod 18 drives the semicircular block 17 to rotate downward. The semicircular block 17 will press against the top of the insertion rod 21 and cannot move upward, thereby achieving a self-locking effect to prevent children from opening the door by themselves, thereby increasing the safety of the folding door.
[0037] Reference Figure 7 , compression spring 26: A cavity 24 is opened on the inner wall of the sliding cavity 27, and the part of the insertion rod 21 located in the cavity 24 is sleeved with a ring 25 and a compression spring 26, and the two ends of the compression spring 26 are respectively fixed on the ring 25 and the inner wall of the top of the cavity 24 to provide a reset force for the insertion rod 21.
[0038] Reference Figure 2 The notch 6 on the side of the door frame 1 is used to expose the pressure plate 7 and the rotating plate 16 so that the same operation can be performed from the other side. A groove 8 is provided on the surface of the second door 3 to serve as a displacement space for the pressure plate 7 on the other side when the pressure plate 7 is pushed in the folded state.
[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
