This utility model, by setting up an assembly / disassembly mechanism and an adjustment mechanism, achieves convenient assembly / disassembly of the device and improves the stability of the device structure.

[0004] Although the above-mentioned device has improved the loading and unloading part, the frame still needs to be aligned before loading and unloading. However, the above-mentioned device and the above-mentioned device have not improved this part, which means that manual alignment is still required, and the alignment must be maintained before loading and unloading operations are carried out, which increases the difficulty of the device.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the problem of frame alignment, the basic concept of the technical solution adopted by this utility model is as follows: A door and window structure that is easy to assemble and disassemble includes a loading and unloading assembly. The loading and unloading assembly is used for self-aligning loading and unloading. The loading and unloading assembly includes a first frame, a calibration frame, a second frame, and calibration blocks. The calibration frames are symmetrically arranged in the first frame, and each calibration frame is fixedly connected to the corresponding first frame. Each calibration block is symmetrically arranged in the second frame, and each calibration block is fixedly connected to the corresponding second frame. The calibration frames and calibration blocks are interlocked and self-locking.

[0007] In a preferred embodiment of this utility model, each calibration frame has symmetrically provided movable spaces, and each movable space of the calibration frame is provided with an arc-shaped spring, and each arc-shaped spring is fixedly connected to the calibration frame.

[0008] In a preferred embodiment of this utility model, each calibration block has a snap-fit ​​space, and the snap-fit ​​space of the calibration block is in contact with the calibration frame and the arc-shaped spring.

[0009] In a preferred embodiment of the present invention, a limiting frame is symmetrically arranged inside the first frame, each limiting frame is slidably connected to the inner wall of the first frame, and a limiting block is symmetrically arranged on each limiting frame.

[0010] In a preferred embodiment of this utility model, each limiting block is fixedly connected to the limiting frame, the upper end of the limiting frame is snapped into the corresponding position of the calibration block, and the limiting block is spatially inserted into the corresponding arc-shaped spring and the calibration frame.

[0011] In a preferred embodiment of this utility model, each limiting frame is threaded with a lead screw, and a transmission rod is fixedly connected between the corresponding lead screws. A gear is fixedly connected to the middle of each transmission rod.

[0013] In a preferred embodiment of this utility model, the threaded rod is rotatably connected to the first frame, and each rack is slidably connected to the corresponding wall surface of the first frame.

[0014] Compared with the prior art, the present invention has the following advantages: 1. This easy-to-assemble and disassemble door and window structure uses the arc shape of the calibration block and calibration frame to guide the alignment of the first and second frames, as well as the space they occupy at the connection between the first and second frames. When the calibration block moves within the calibration frame, it compresses the arc-shaped spring to move inward. After the calibration block and the calibration frame wall are fully in contact, the arc-shaped spring deforms and resets, and then fits into the corresponding position within the calibration block. This achieves both self-guiding alignment and self-locking capability. In addition, the connection between the calibration frame and the calibration block also enhances the resistance to lateral forces at the connection between the first and second frames.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] Please see Figure 1-5 A door and window structure that is easy to assemble and disassemble includes a loading and unloading assembly. The loading and unloading assembly is used for self-aligning loading and unloading. The loading and unloading assembly includes a first frame 1, a calibration frame 11, a second frame 2, and a calibration block 21. The calibration frames 11 are symmetrically arranged in the first frame 1, and each calibration frame 11 is fixedly connected to the corresponding first frame 1. Each calibration block 21 is symmetrically arranged in the second frame 2, and each calibration block 21 is fixedly connected to the corresponding second frame 2. The calibration frames 11 and the calibration blocks 21 are inserted and self-locked. During the assembly and disassembly of the first frame 1 and the second frame 2, the first frame 1 and the second frame 2 can be slightly aligned and then directly inserted. The calibration block 21 and the calibration frame 11 guide the alignment between the first frame 1 and the second frame 2 through their own shapes, and the calibration block 21 and the calibration frame 11 can self-lock, realizing the self-alignment and self-locking between the first frame 1 and the second frame 2.

[0021] It is worth noting that the self-locking mechanism between calibration block 21 and calibration frame 11 serves a guiding function, which is more inclined towards self-alignment. This will not be elaborated upon here, but will be discussed in detail below.

[0022] Each calibration frame 11 has symmetrically provided movable spaces, and each calibration frame 11 has an arc-shaped spring 12 in its movable space. Each arc-shaped spring 12 is fixedly connected to the calibration frame 11. Each calibration block 21 has a snap-fit ​​space, and the snap-fit ​​space of the calibration block 21 fits against the calibration frame 11 and the arc-shaped spring 12. During the assembly and disassembly of the first frame 1 and the second frame 2, the first frame 1 and the second frame 2 can be slightly aligned and then directly inserted. The calibration block 21 and the calibration frame 11 are aligned by their own arc shape and the space occupied by the calibration frame 11 and the calibration block 21 at the connection part of the first frame 1 and the second frame 2. As the calibration block 21 moves within the calibration frame 11, it squeezes the arc-shaped spring 12 to move inward. After the calibration block 21 and the wall of the calibration frame 11 are completely attached, the arc-shaped spring 12 deforms and resets and attaches to the corresponding position within the calibration block 21, realizing the function of self-guided alignment and having the ability to lock. Furthermore, the connection between the calibration frame 11 and the calibration block 21 enhances the resistance to lateral forces at the connection position of the first frame 1 and the second frame 2.

[0023] The first frame 1 is symmetrically provided with limiting frames 3. Each limiting frame 3 is slidably connected to the inner wall of the first frame 1. Each limiting frame 3 is symmetrically provided with limiting blocks 32. Each limiting block 32 is fixedly connected to the limiting frame 3. The upper end of the limiting frame 3 is engaged with the corresponding position of the calibration block 21. The limiting block 32 is spatially inserted with the corresponding arc-shaped spring 12 and the calibration frame 11. Each limiting frame 3 is threadedly connected with a lead screw 31. A transmission rod 4 is fixedly connected between the corresponding lead screws 31. A gear 41 is fixedly connected to the middle of each transmission rod 4. Each gear 41 meshes with a rack 42. Each rack 42 is threadedly connected with a threaded rod 43. The threaded rod 43 is rotatably connected to the first frame 1. Each rack 42 is slidably connected to the corresponding wall surface of the first frame 1. When both ends of the first frame 1 are aligned with the second frame 2 and self-locked, the threaded rod 43 is manually rotated. The threaded rod 43 drives the rack 42 to rise and fall through the threaded transmission. The rack 42 meshes with the gear 41. The gear 41 drives the transmission rod 4 to rotate. The rotation of the transmission rod 4 drives the lead screw 31 at both ends to rotate. The lead screw 31 retracts the limiting frame 3 at both ends inward through the threaded transmission. The upper end of the limiting frame 3 engages with the calibration block 21. The limiting block 32 is inserted into the gap between the calibration frame 11 and the arc-shaped spring 12. Thus, the limiting frame 3 restricts the position of the calibration block 21 and the position of the arc-shaped spring 12, locking the connection between the calibration block 21 and the calibration frame 11. This ensures a stable connection between the first frame 1 and the second frame 2 without the need for excessive operation. When it is necessary to disassemble the first frame 1 and the second frame 2, rotate the threaded rod 43 in the opposite direction. Through the transmission of the screw 31, transmission rod 4, gear 41 and rack 42, the limiting frame 3 and limiting block 32 are moved away from the calibration frame 11 and calibration block 21, releasing the positional restriction between the calibration frame 11 and calibration block 21. Then, simply pull the first frame 1 and the second frame 2 together to complete the disassembly. The locking and unlocking between the first frame 1 and the second frame 2 can be completed by simply turning the threaded rod 43. The separation between the first frame 1 and the second frame 2 can also be completed by manually pulling.

[0024] Working principle: During the assembly and disassembly of the first frame 1 and the second frame 2, the first frame 1 and the second frame 2 can be slightly aligned and then directly inserted. The calibration block 21 and the calibration frame 11 guide the alignment of the first frame 1 and the second frame 2 through their own shape, and the calibration block 21 and the calibration frame 11 can self-lock, achieving self-alignment and self-locking between the first frame 1 and the second frame 2. During the assembly and disassembly of the first frame 1 and the second frame 2, the first frame 1 and the second frame 2 can be slightly aligned and then directly inserted. The calibration block 21 and the calibration frame 11 can self-lock, achieving self-alignment and self-locking between the first frame 1 and the second frame 2. By utilizing their own arc shape and the space occupied by the calibration frame 11 and calibration block 21 at the connection between the first frame 1 and the second frame 2, the alignment between the first frame 1 and the second frame 2 is guided. As the calibration block 21 moves within the calibration frame 11, it compresses the arc-shaped spring 12 inward. After the calibration block 21 is fully attached to the wall of the calibration frame 11, the arc-shaped spring 12 deforms and resets, attaching to the corresponding position within the calibration block 21. This achieves self-guided alignment while also possessing self-locking capability. Furthermore, the connection between the calibration frame 11 and the calibration block 21 enhances the resistance to lateral forces at the connection point between the first frame 1 and the second frame 2. When both ends of the first frame 1 are aligned with the second frame... After frame 2 is aligned and self-locked, the threaded rod 43 is manually rotated. The threaded rod 43 drives the rack 42 to rise and fall through the threaded transmission. The rack 42 meshes with the gear 41, which drives the transmission rod 4 to rotate. The rotation of the transmission rod 4 drives the lead screws 31 at both ends to rotate. The lead screws 31 retract the limiting frames 3 at both ends through the threaded transmission. The upper end of the limiting frame 3 engages with the calibration block 21. The limiting block 32 is inserted into the gap between the calibration frame 11 and the arc-shaped spring 12. Thus, the limiting frame 3 restricts the position of the calibration block 21, and the limiting block 32 restricts the position of the arc-shaped spring 12, locking the connection between the calibration block 21 and the calibration frame 11 to ensure the first The connection between frame 1 and second frame 2 is stable and requires no excessive operation. When it is necessary to disassemble the first frame 1 and the second frame 2, rotate the threaded rod 43 in the opposite direction. Through the transmission of the screw 31, transmission rod 4, gear 41 and rack 42, the limiting frame 3 and limiting block 32 are moved away from the calibration frame 11 and calibration block 21, releasing the positional restriction between the calibration frame 11 and calibration block 21. Then, simply pull the first frame 1 and the second frame 2 together to complete the disassembly. The locking and unlocking between the first frame 1 and the second frame 2 can be completed by simply turning the threaded rod 43. The separation between the first frame 1 and the second frame 2 can also be completed by manually pulling.
