Technical Field

[0001] This utility model relates to the field of window frame technology, and in particular to a detachable prefabricated window frame. Background Technology

[0002] Precast window frames are window frame products that are prefabricated in a factory. They are usually produced using specific materials and processes and then transported to the construction site for installation.

[0003] In existing technologies, such as the Chinese patent CN211598236U entitled "A Prefabricated Window Frame for Easy Disassembly," a window frame body is included, set within a pre-reserved opening in a wall panel. Fixing studs are provided on both side walls of the window frame body. One end of each stud is movably connected to the inner side walls of the window frame body, and the other end is provided with an anti-pressure plate, which is tightly connected to the wall panel. A locking nut is also provided on the fixing stud. This invention has a simple structure and is easy to install; disassembly and assembly can be achieved simply by rotating the locking nut. Additionally, the use of gaskets at various external connections effectively prevents mechanical damage and maintains the aesthetic appearance of the window frame body. However, disassembly of this window frame requires the use of tools to tighten multiple locking nuts, which is relatively cumbersome and time-consuming. Especially in scenarios requiring rapid window frame replacement or maintenance, frequent tool operation of multiple nuts reduces work efficiency. Therefore, an improvement is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that multiple locking nuts still need to be tightened with tools when disassembling window frames, and to propose a detachable prefabricated window frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable prefabricated window frame, comprising a wall and a window frame body, wherein glass is fixedly installed inside the window frame body, and limit holes are symmetrically opened on both sides of the interior of the wall, and slots are opened inside the top and bottom of the window frame body, a guide rod is fixedly installed inside the slot, a bidirectional screw is rotatably connected to the inside of the slot, a sliding plate is symmetrically threaded to the outer wall of the bidirectional screw, a limit pin is symmetrically fixedly installed on one side of the sliding plate, a worm gear is fixedly installed to the outer wall of the bidirectional screw, a worm is rotatably connected to the inside of the slot, and a knob is fixedly installed at one end of the worm.

[0006] Preferably, the outer wall of the knob is provided with anti-slip grooves evenly distributed.

[0007] Preferably, the limiting post and the limiting hole are slidably connected, and the window frame body and the limiting post are slidably connected.

[0008] Preferably, the sliding plate is slidably connected to the guide rod, and the window frame body is slidably connected to the wall.

[0009] Preferably, the worm gear and the worm are meshed with each other.

[0010] Preferably, reinforcing rods are symmetrically fixedly installed on the inner side of the window frame body, and the reinforcing rods are fixedly connected to the glass.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model, by incorporating a knob, worm gear, worm wheel, two-way lead screw, sliding plate, limiting post, and guide rod, enables quick installation and disassembly of the window frame body without the need for tools. During installation, simply rotating the knob allows the limiting post to be inserted into the limiting hole in the wall, firmly fixing the window frame body to the wall. During disassembly, rotating the knob in the opposite direction allows the limiting post to exit the limiting hole, easily separating the window frame body from the wall. This design greatly improves the efficiency of window frame body installation and disassembly, and has significant advantages, especially in scenarios requiring rapid replacement of the window frame body or maintenance work.

[0013] 2. In this utility model, the reinforcing rod can prevent the glass from cracking or loosening due to external forces, and at the same time help to improve the overall rigidity of the window frame body, so that it can better withstand various external forces. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a detachable prefabricated window frame, including a wall 1 and a window frame body 2. Glass 3 is fixedly installed inside the window frame body 2. Limiting holes 4 are symmetrically opened on both sides of the inside of the wall 1. A groove 5 is opened inside the top and bottom of the window frame body 2. A guide rod 6 is fixedly installed inside the groove 5. A bidirectional screw 7 is rotatably connected to the inside of the groove 5. A sliding plate 8 is symmetrically threaded to the outer wall of the bidirectional screw 7. A limiting post 9 is symmetrically fixedly installed on one side of the sliding plate 8. A worm gear 10 is fixedly installed on the outer wall of the bidirectional screw 7. A worm 11 is rotatably connected to the inside of the groove 5. A knob 12 is fixedly installed at one end of the worm 11. Anti-slip grooves 13 are evenly opened on the outer wall of the knob 12. The limiting post 9 is slidably connected to the limiting hole 4. The window frame body 2 is slidably connected to the limiting post 9. The sliding plate 8 is slidably connected to the guide rod 6. The window frame body 2 is slidably connected to the wall 1. The worm gear 10 and the worm 11 are meshed with each other.

[0023] In this embodiment, by setting up structures such as knob 12, worm gear 11, worm wheel 10, two-way lead screw 7, sliding plate 8, limiting post 9, and guide rod 6, the function of quickly installing and disassembling the window frame body 2 without the use of tools is realized. During installation, simply turn knob 12 to insert the limiting post 9 into the limiting hole 4 of the wall 1, and firmly fix the window frame body 2 to the wall 1. During disassembly, turn knob 12 in the opposite direction to make the limiting post 9 exit the limiting hole 4, and easily separate the window frame body 2 from the wall 1. This design greatly improves the efficiency of installing and disassembling the window frame body 2, and has significant advantages, especially in scenarios where it is necessary to quickly replace the window frame body 2 or perform maintenance work.

[0024] Example 2: As Figure 1 and Figure 3 As shown, reinforcing rods 14 are symmetrically fixedly installed on the inner side of the window frame body 2, and the reinforcing rods 14 are fixedly connected to the glass 3.

[0025] In this embodiment, the reinforcing rod 14 can prevent the glass 3 from cracking or loosening due to external forces, and at the same time help to improve the overall rigidity of the window frame body 2, so that it can better withstand various external forces.

[0026] The working principle of this embodiment is as follows: During installation, first align the window frame body 2 with the installation position on the wall 1. After alignment, rotate the knob 12. The knob 12 drives the worm gear 11 to rotate. Since the worm gear 11 and the worm wheel 10 are meshed with each other, the rotation of the worm gear 11 will drive the worm wheel 10 to rotate. During the rotation of the worm wheel 10, it will drive the double-acting screw 7 to rotate inside the slot 5. When the double-acting screw 7 rotates, the sliding plate 8, which is symmetrically threaded on its outer wall, will slide along the guide rod 6 in the slot 5. As the sliding plate 8 moves, the limiting pins 9, which are symmetrically fixed on one side of the sliding plate 8, will gradually... The window frame body 2 is moved towards the limiting hole 4 inside the wall 1. When the limiting pin 9 is fully inserted into the limiting hole 4, the window frame body 2 is firmly fixed to the wall 1. When it is necessary to disassemble the window frame body 2, the knob 12 is rotated in the opposite direction. The knob 12 drives the worm gear 11 to rotate in the opposite direction. The worm gear 11 then drives the worm wheel 10 and the double-acting screw 7 to rotate in the opposite direction. At this time, the sliding plate 8 will drive the limiting pin 9 to exit from the limiting hole 4 inside the wall 1. When the limiting pin 9 is completely out of the limiting hole 4, the connection between the window frame body 2 and the wall 1 is released, and the window frame body 2 can be easily removed from the wall 1. During use, the reinforcing rod 14 can prevent the glass 3 from breaking or loosening due to external forces, and also helps to improve the overall rigidity of the window frame body 2, so that it can better withstand various external forces.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
