Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window subframe technology, specifically to an insulated door and window with an easily removable subframe. Background Technology
[0002] A subframe, also known as a secondary frame, is an additional frame installed outside the main window frame. It enhances the window's sealing, waterproofing, and decorative effect. Subframes can be made of materials such as steel, aluminum, or wood; the specific choice depends on the project's needs and budget.
[0003] Currently, most door and window subframes on the market are fixedly installed on the wall. When the building is demolished, the subframes are often damaged. In some temporary buildings for short-term use, the use of fixed, non-reusable, and inconveniently disassembled door and window subframes undoubtedly increases the cost of the building. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides an insulated door and window with an easily detachable subframe, thereby solving the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an insulated door and window with an easy-to-disassemble subframe, wherein an installation block is fixedly installed on the rear side of the window frame, a fixing block is provided on the outer side of the installation block, an upper fixing frame is provided on the top surface of the fixing block, a side fixing frame is provided on the side of the fixing block, an installation frame is movably installed on the bottom side of the upper fixing frame, a hinge is fixedly installed on the inner side of the installation frame, a glass window is fixedly installed on the inner side of the installation frame via the hinge, and a handle is fixedly installed on the front side of the glass window.
[0008] Preferably, the top and bottom sides of the mounting frame are provided with adjustment port one and adjustment port two, and the bottom surfaces of adjustment port one and adjustment port two are provided with adjustment hole one and adjustment hole two, and the adjustment port one and adjustment port two communicate with the interior of adjustment hole one and adjustment hole two.
[0009] Preferably, a base plate is fixedly installed on the bottom surface of the upper fixed frame.
[0010] Preferably, a base plate two is fixedly installed on the side of the side fixing frame.
[0011] Preferably, the fixing block has a locking hole on its front side.
[0012] Preferably, the number of fixing blocks corresponds to the number of mounting blocks.
[0013] Compared with the prior art, this utility model provides an insulated door and window with an easy-to-disassemble subframe, which has the following advantages:
[0014] 1. This insulated door and window with easy-to-disassemble subframes requires, firstly, pre-reserving the installation groove for the subframe on the wall where the subframe needs to be installed, placing the installation frame in the installation groove, and then adjusting the positions of the upper and lower fixed frames and the side fixed frames at the left and right ends according to the size of the pre-reserved installation groove. The top surfaces of the base plate one and the floor two are provided with rubber layers. When the top surfaces of the base plate one and the base plate two are in contact with the bottom surfaces of the adjustment holes one and the adjustment holes two, gaps can be reduced to prevent heat loss.
[0015] 2. This insulated door and window with easy-to-disassemble subframe can be adjusted to the desired position and then placed with fixing blocks at the four corners. After the four corners are supported by the fixing blocks, the mounting frame can be clamped into the reserved mounting groove. At this time, the glass window can be installed and fixed. After the glass window is installed, align the mounting blocks on the window frame with the locking holes and fasten them. After pressing the mounting blocks on the window frame with the locking holes, the installation structure of the window frame can be covered to prevent dust from falling in, and the appearance can be more concise.

[0024] 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.
[0025] like Figure 1-7 As shown, this utility model provides a technical solution: an insulated door and window with an easy-to-disassemble subframe. An installation block 101 is fixedly installed on the rear side of the window frame 1. A fixing block 5 is provided on the outer side of the installation block 101. An upper fixing frame 3 is provided on the top surface of the fixing block 5. A side fixing frame 4 is provided on the side of the fixing block 5. An installation frame 2 is movably installed on the bottom side of the upper fixing frame 3. A hinge 6 is fixedly installed on the inner side of the installation frame 2. A glass window 7 is fixedly installed on the inner side of the installation frame 2 through the hinge 6. A handle 8 is fixedly installed on the front side of the glass window 7.
[0026] Furthermore, the top and bottom sides of the mounting frame 2 are provided with adjustment port 1 202 and adjustment port 204, and the bottom surfaces of adjustment port 1 202 and adjustment port 204 are provided with adjustment hole 1 201 and adjustment hole 203, and adjustment port 1 202 and adjustment port 204 are connected to the interior of adjustment hole 1 201 and adjustment hole 203.
[0027] Through the above technical solution, the upper fixed frame 3 and the side fixed frame 4, which are movably installed in the mounting frame 2, can be adjusted to meet the size requirements of windows of different specifications.
[0028] Furthermore, a base plate 301 is fixedly installed on the bottom surface of the upper fixed frame 3.
[0029] With the above technical solution, when the fixing block 5 is placed on the lower side of the upper fixing frame 3 and the side of the side fixing frame 4, the bottom plate 301 will contact the inner side of the mounting frame 2, so that the size of the subframe can be adjusted.
[0030] Furthermore, a base plate 401 is fixedly installed on the side of the side fixing frame 4.
[0031] Through the above technical solution, the base plate 2 401 allows the side fixing frame 4 to be adjusted to the expected size when the fixing block 5 is placed on the side of the side fixing frame 4.
[0032] Furthermore, a locking hole 501 is provided on the front side of the fixing block 5.
[0033] By using the above technical solution, after aligning the mounting block 101 on the window frame 1 with the locking hole 501 and pressing it tightly, the mounting structure of the window frame 1 can be covered to prevent dust from falling in, and the appearance can be more concise.
[0034] Furthermore, the number of fixing blocks 5 corresponds to the number of mounting blocks 101.
[0035] Through the above technical solution, the corresponding number of mounting blocks 101 and fixing blocks 5 can ensure that the window frame 1 can be installed stably to avoid falling and causing damage.
[0036] Working principle: First, reserve the installation groove for the subframe on the wall where it needs to be installed. Place the installation frame 2 in the installation groove. Then, according to the size of the reserved installation groove, adjust the position of the upper fixing frame 3 and the side fixing frame 4 at the top and bottom and left and right ends. After adjusting to the expected position, place the fixing blocks 5 at the four corners. After the fixing blocks 5 support the four corners, the installation frame 2 can be locked in the reserved installation groove. At this time, install and fix the glass window 7. After the glass window 7 is installed, align the installation block 101 on the window frame 1 with the locking hole 501 and fasten it.
