Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to a door and window structure that is easy to assemble and disassemble. Background Technology
[0002] Doors and windows are classified as enclosure components or partition components according to their location, and have different design requirements. They have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements include energy conservation. In cold regions, heat loss through gaps in doors and windows accounts for about 25% of the total heating energy consumption. The airtightness of doors and windows is an important aspect of energy-saving design. Doors and windows are important components of the building envelope system. They are mainly composed of an outer frame and an inner frame. Usually, the inner frame is installed on the outer frame. When the window is damaged, only the inner frame needs to be disassembled and reassembled. However, since the installation of the inner frame usually uses multiple bolts, a large number of bolts are usually installed to ensure the stability of the inner frame installation. This results in a large workload and inconvenient disassembly and assembly. Therefore, we propose a door and window structure that is easy to disassemble and assemble. Utility Model Content

[0022] 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.
[0023] Please see Figures 1 to 7 A door and window structure that is easy to assemble and disassemble includes a fixed outer frame 1. An inner frame is installed on the inner side of the fixed outer frame 1. The inner frame is composed of vertical frames 2 and horizontal frames 3. The vertical frames 2 and horizontal frames 3 are spliced together to facilitate assembly and disassembly. The outer sides of the vertical frames 2 and horizontal frames 3 are in contact with the inner side of the fixed outer frame 1. Under the action of the fixed outer frame 1, the insertion relationship of the vertical frames 2 and horizontal frames 3 can be locked. The interior of the fixed outer frame 1 and the vertical frames 2 are both circularly movably fitted with rotatable locking pins 4. The rotatable locking pins 4 can rotate in a fixed position and extend into the fixed outer frame 1 or the vertical frame 2 to lock the connection between them. The locking mechanism is achieved by rotating the inner sides of the locking pins 4 to contact each other and form a circle. The center of this circle is located on the contact surface between the fixed outer frame 1 and the vertical frame 2. The fixed outer frame 1 and the vertical frame 2 are connected by a threaded bolt 5. With the connection of the bolt 5, the fixed outer frame 1 and the vertical frame 2 can be locked together, making the locking more stable. The bolt 5 passes through the middle of the circle between the rotating locking pins 4, and a plug-in linkage plate 10 is movably connected to the bolt 5 to engage with the inner side of the rotating locking pin 4. The plug-in linkage plate 10 can be plugged into the rotating locking pin 4, thereby driving the rotating locking pin 4 to rotate and engage.
[0024] Please see Figures 1 to 8 The vertical frame 2 is fixedly connected to the middle of both ends with a first pin 12, and the vertical frame 2 is provided with a first slot 11 at both ends. The horizontal frame 3 is provided with a second slot 14 at the middle of both ends, and the horizontal frame 3 is fixedly connected to the middle of both ends with a second pin 13. The first pin 12 is inserted into the second slot 14, and the first slot 11 is inserted into the second pin 13. Through the insertion of the first pin 12 and the second slot 14 into the first slot 11 and the second pin 13, the vertical frame 2 and the horizontal frame 3 can be stably connected.
[0025] Please see Figures 1 to 7 A connecting ring plate 9 is fixedly connected to the top of the plug-in linkage plate 10. Under the drive of the connecting ring plate 9, the plug-in linkage plate 10 can move smoothly relative to each other. Multiple connecting posts 7 are fixedly connected to one side of the connecting ring plate 9. Under the drive of the connecting posts 7, the connecting ring plate 9 can move smoothly relative to each other. The connecting posts 7 are all movably connected to the bolts 5. The connecting posts 7 can move on the bolts 5 along a fixed trajectory and can rotate under the drive of the bolts 5.
[0026] Please see Figures 1 to 7 One end of the connecting column 7 passes through the bolt 5 and is fixedly connected to the pull ring 6. By pulling the pull ring 6, the connecting column 7 can move. The pull ring 6 contacts the bolt 5, and the connecting ring plate 9 contacts the rotating locking pin 4.
[0027] Please see Figures 1 to 7 A limiting spring 8 is sleeved on the connecting column 7. One end of the limiting spring 8 is fixed to the connecting ring plate 9, and the other end of the limiting spring 8 is fixed to the bolt 5. Under the action of the limiting spring 8, the plug-in linkage plate 10 can automatically rotate and plug in the locking pin 4. Under the action of the limiting spring 8, the friction of rotating the locking pin 4 and the friction between the threads of the bolt 5 can be increased, thus making the locking more secure.
[0028] Please see Figures 1 to 7 The double arc structure of the rotating locking pin 4 is concentric, and one end of the double arc structure is connected. The angle of the outer arc structure of the rotating locking pin 4 is less than 180 degrees, which allows the rotating locking pin 4 to rotate and engage smoothly.
[0029] In summary, this easy-to-assemble and disassemble door and window structure, when in use, involves inserting the first slot 11 into the second pin 13 and the first pin 12 into the second slot 14, thereby enabling the installation of the vertical frame 2 and the horizontal frame 3. Afterwards, it is installed inside the fixed outer frame 1. First, pull out the pulling ring 6, which allows the connecting plate 10 to be pulled outwards. Then, tighten the bolt 5, allowing it to be tightened and installed into the fixed outer frame 1 and the vertical frame 2. Afterwards, release the pulling ring 6 and continue tightening the bolt. 5. Driven by bolt 5, the connecting column 7 can drive the plug-in linkage plate 10 to rotate. Under the action of the limiting spring 8, the plug-in linkage plate 10 can be plugged into the rotating locking pin 4 when it rotates to the corresponding position. Then, driven by the rotation of bolt 5, the plug-in linkage plate 10 can drive the rotating locking pin 4 to rotate, so that the rotating locking pin 4 can lock the fixed outer frame 1 and the vertical frame 2, thereby locking them together.
