Description

Technical Field

[0001] This utility model relates to the field of door frame assembly technology, and in particular to a male-female connecting rod for assembling door frames. Background Technology

[0002] Door frame is an architectural and interior design term referring to the two door frames, one inside and one outside. Its main functions are to secure the door leaf, protect the corners of walls, and provide decoration.

[0003] Current door frames are constructed by connecting horizontal and vertical frames sequentially. The horizontal and vertical frames are fastened together by connectors. However, the connection between the horizontal and vertical frames is achieved by drilling multiple threaded holes on their side walls and then fixing them with multiple screws. This process is cumbersome and makes it difficult to disassemble and repair the door frame. Furthermore, the screw connection puts pressure on the inside of the door frame, which can easily cause cracks to appear inside the door frame. This can lead to instability in the door frame after long-term use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a male-female connecting rod for assembling door frames.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A connecting rod for assembling a door frame includes a horizontal frame, a vertical frame, and a connecting rod. The horizontal and vertical frames are joined at right angles. The side wall of the horizontal frame has a threaded groove, and the end of the threaded groove near the vertical frame extends through the side wall of the vertical frame. A female connecting rod is fixedly connected to the inner wall of the threaded groove. One end of the connecting rod has a slot that mates with the female connecting rod. The connecting rod is located within the threaded groove. A circular plate is threadedly connected to the inner wall of the threaded groove away from the female connecting rod. The side wall of the circular plate has an internal hexagonal groove. The lower end of the horizontal frame is fixedly connected to the side wall of the connecting rod by multiple bolts. The horizontal and vertical frames are provided with fixing mechanisms for fixing them.

[0007] Preferably, the fixing mechanism includes multiple sliding grooves formed on the upper surface of the horizontal frame near the vertical frame, and multiple sliding rods corresponding to the multiple sliding grooves are fixedly connected to the lower surface of the vertical frame.

[0008] Preferably, two first limiting plates are fixedly connected to the inner wall of the slide groove, and two second limiting plates are fixedly connected to the side wall of the slide rod.

[0009] Preferably, the sidewalls of the first limiting plate and the second limiting plate that are close to each other are inclined.

[0010] Preferably, both the first limiting plate and the second limiting plate are made of plastic material.

[0011] Preferably, the lower end of the cross frame is provided with multiple circular grooves, and the lower ends of the multiple bolts are respectively located in the multiple circular grooves.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting threaded grooves, sub-connecting rods, female connecting rods, circular plates, and bolts, the sub-connecting rods are connected to the female connecting rods through slots, and then connected to the sub-connecting rods with bolts. Subsequently, the circular plate is threaded to the inner wall of the threaded groove, thereby completely fixing the sub-connecting rods. This fixes the connection between the horizontal and vertical frames in the vertical direction without the need for multiple screws, making the operation simple and preventing cracks inside the horizontal and vertical frames, thus ensuring its quality of use.

[0014] 2. By setting a fixing mechanism, when the horizontal and vertical frames are spliced ​​at right angles, the sliding rod is inserted into the corresponding sliding groove. At this time, the second limiting plate will press against the first limiting plate. When the lower end of the sliding rod contacts the bottom of the sliding groove, the second limiting plate moves to the lower end of the first limiting plate, thereby fixing the position of the sliding rod and fixing the connection between the horizontal and vertical frames in the horizontal direction, thus increasing its installation firmness.

[0021] Reference Figure 1-3 A connecting rod for assembling a door frame includes a horizontal frame 1, a vertical frame 2, and a connecting rod 4. The horizontal frame 1 and the vertical frame 2 are joined at right angles. The side wall of the horizontal frame 1 has a threaded groove 3. The end of the threaded groove 3 near the vertical frame 2 passes through the side wall of the vertical frame 2. A female connecting rod 5 is fixedly connected to the inner wall of the threaded groove 3. One end of the connecting rod 4 has a slot 6 that mates with the female connecting rod 5. The connecting rod 4 is located inside the threaded groove 3. A circular plate 7 is threadedly connected to the inner wall of the threaded groove 3 away from the female connecting rod 5. The side wall of the circular plate 7 has an internal hexagonal groove 8. The lower end of the horizontal frame 1 is fixedly connected to the side wall of the connecting rod 4 by multiple bolts 9. The horizontal frame 1 and the vertical frame 2 are provided with fixing mechanisms for fixing them.

[0022] Furthermore, an external hex wrench is placed in the internal hexagonal groove 8, which allows the circular plate 7 to be rotated so that it is threadedly connected to the inner wall of the threaded groove 3.

[0023] The fixing mechanism includes multiple sliding grooves 11 formed on the upper surface of the horizontal frame 1 near the vertical frame 2, and multiple sliding rods 12 corresponding to the multiple sliding grooves 11 are fixedly connected to the lower surface of the vertical frame 2.

[0024] Two first limiting plates 13 are fixedly connected to the inner wall of the slide 11, and two second limiting plates 14 are fixedly connected to the side wall of the slide rod 12.

[0025] The sidewalls of the first limiting plate 13 and the second limiting plate 14 that are close to each other are inclined, so that the second limiting plate 14 can press the first limiting plate 13.

[0026] Both the first limiting plate 13 and the second limiting plate 14 are made of plastic material, which allows the first limiting plate 13 and the second limiting plate 14 to have a certain degree of flexibility. When the second limiting plate 14 presses against the first limiting plate 13, the first limiting plate 13 can bend to allow the second limiting plate 14 to move downward. When the second limiting plate 14 moves downward and separates from the first limiting plate 13, the first limiting plate 13 immediately returns to its initial state.

[0027] The lower end of the horizontal frame 1 has multiple circular grooves 10, and the lower ends of multiple bolts 9 are respectively located in the multiple circular grooves 10.

[0028] In this utility model, when the horizontal frame 1 and the vertical frame 2 are installed, multiple sliding rods 12 located at the lower end of the vertical frame 2 are inserted into multiple corresponding sliding grooves 11. Then, the second limiting plate 14 presses against the first limiting plate 13, so that the first limiting plate 13 can bend and the second limiting plate 14 moves down. When the lower end of the sliding rod 12 contacts the bottom of the sliding groove 11, the second limiting plate 14 moves to the lower end of the first limiting plate 13. Then, the first limiting plate 13 immediately returns to its initial state, thereby fixing the position of the sliding rod 12, and thus fixing the connection between the horizontal frame 1 and the vertical frame 2 in the horizontal direction.

[0029] Then, insert the sub-connecting rod 4 into the threaded groove 3, and make the inner wall of the slot 6 fit with the side wall of the female connecting rod 5. Then, place the external hexagonal wrench in the internal hexagonal groove 8, and then rotate the round plate 7 to make it threadedly connected with the inner wall of the threaded groove 3, thereby fixing the sub-connecting rod 4 in the threaded groove 3. Then, rotate multiple bolts 9 to fix the sub-connecting rod 4 again, thereby fixing the connection between the horizontal frame 1 and the vertical frame 2 in the vertical direction and increasing its installation firmness.
