Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 , Figure 2 , Figure 4 , a retractable metal door and window frame convenient for maintenance, including a frame 1. Two symmetrically distributed threaded holes 2 are opened inside the frame 1. A connecting frame 3 is in contact with the top of the frame 1. Two symmetrically distributed connecting rods 6 are fixedly connected to the bottom of the connecting frame 3. The connecting rods 6 are slidably connected to the frame 1. A connecting strip 4 is slidably sleeved inside the front end of the frame 1. An adjusting mechanism 7 is arranged on the connecting rod 6, and a connecting mechanism 8 is arranged on the connecting strip 4.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3, the adjusting mechanism 7 includes a communication port 71. A plurality of communication ports 71 are evenly distributed inside the connecting rod 6. One of the communication ports 71 is communicated with the threaded hole 2. An inclined groove 72 is formed inside the frame 1. An inclined block 73 is slidably sleeved inside the inclined groove 72. The number of the inclined grooves 72 is multiple, and the multiple inclined grooves 72 are evenly distributed inside the frame 1. By designing a plurality of inclined grooves 72, the inclined block 73 can slide into the inclined grooves 72 at different positions. The inclined block 73 is slidably connected with the connecting rod 6. A guide rod 74 is slidably sleeved inside the inclined block 73. The guide rod 74 is fixedly connected with the connecting rod 6. A first spring 75 is arranged on the outer side of the guide rod 74. One end of the first spring 75 is fixedly connected with the inclined block 73, and the other end of the first spring 75 is fixedly connected with the connecting rod 6. By designing the first spring 75, the acting force of the first spring 75 can act on the inclined block 73. By designing the adjusting mechanism 7, it is convenient to adjust the position of the connecting frame 3.

[0023] Please refer to Figure 1 , Figure 4 , Figure 5 , the connecting mechanism 8 includes a plug rod 81. The plug rod 81 is slidably sleeved inside the frame 1. A push rod 82 is fixedly connected to the outer side of the plug rod 81. The push rod 82 is slidably connected with the connecting strip 4. A sliding rod 83 is fixedly connected to the end of the push rod 82 away from the plug rod 81. The sliding rod 83 is slidably connected with the connecting strip 4. A second spring 84 is arranged on the outer side of the sliding rod 83. One end of the second spring 84 is fixedly connected with the connecting strip 4, and the other end of the second spring 84 is fixedly connected with the slider 85. By designing the second spring 84, the acting force of the second spring 84 can act on the slider 85. The slider 85 is fixedly sleeved on the outer side of the sliding rod 83. The slider 85 is slidably connected with the connecting strip 4. By designing the connecting mechanism 8, it is convenient to disassemble the connecting strip 4.

[0024] The specific implementation process of the present utility model is as follows: When in use, when it is necessary to adjust the position of the connecting frame 3, directly pull up the connecting frame 3. The connecting frame 3 drives the connecting rod 6 to move. The connecting rod 6 drives the inclined block 73 to move. The inclined block 73 will slide along the inclined surface of the inclined groove 72. The inclined block 73 will be extruded to move horizontally. The inclined block 73 will slide along the guide rod 74. The inclined block 73 will squeeze the first spring 75, which can separate the inclined block 73 from the inclined groove 72. As the connecting rod 6 moves, under the elastic action of the first spring 75, the inclined block 73 will reset and insert into the inclined groove 72 at another position, so that the relative position between the connecting rod 6 and the frame 1 can be adjusted and fixed. After the adjustment is completed, the threaded hole 2 and the communication port 71 are connected by bolts to firmly fix the relative position between the frame 1 and the connecting frame 3. Through the design of the telescopic door and window frame, it is convenient to flexibly adjust the size of the door and window frame and facilitate adapting to the installation requirements of different sizes.

[0025] When it is necessary to disassemble the connecting bar 4, push the push rod 82 horizontally. The push rod 82 drives the sliding rod 83 and the slider 85 to move horizontally. The slider 85 will squeeze the second spring 84, and then the push rod 82 will drive the insertion rod 81 to move horizontally, so that the insertion rod 81 is separated from the frame 1. Subsequently, the connecting bar 4 can be removed from the inside of the frame 1, so that the frame 1 can be opened, and the opening size of the frame 1 can be increased. Furthermore, after the window screen and the like are installed, it is convenient to disassemble and maintain them.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
