Description

Technical Field

[0001] This utility model relates to the field of installation and fixing technology of wooden doors in building decoration and renovation, and specifically to a wooden door frame installation and connection structure. Background Technology

[0002] With the development of the decoration industry, pre-installed wooden doors have become widely used. Due to their ease of installation and diverse styles, they are increasingly popular. Traditionally, when installing pre-installed wooden doors, the door frame is first leveled and straightened using wooden wedges, then temporarily secured on both sides with wooden blocks and self-tapping screws. Finally, expanding foam is used to fill the gap between the wall and the door frame. After the foam hardens, the temporary fixing blocks are removed before proceeding with other installation work. This method is inefficient for leveling and straightening the door frame. The use of wooden blocks and self-tapping screws for temporary fixation and subsequent removal wastes installation time and is inefficient. Furthermore, relying solely on expanding foam to fix the door frame may cause it to loosen and fall off after prolonged use or frequent opening, posing a safety hazard and potentially causing door leaf deformation and difficulty in opening.

[0003] To address the above issues, there is an urgent need for a new door frame installation and connection structure. This structure should replace the traditional method of using wooden blocks and self-tapping screws for temporary fixing by installing connectors. This would improve installation efficiency and connection strength, and solve problems such as door frames loosening and falling off after prolonged use or frequent opening of wooden doors, which could pose safety hazards, or cause door leaf deformation and inflexible opening. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, a new door frame installation and connection structure is provided. This structure features a rational design, replacing the traditional method of using wooden blocks and self-tapping screws for temporary fixing with connectors. The installation process is simple, improving installation efficiency and connection strength. It solves the problems of door frames loosening and falling off after prolonged use or frequent opening of wooden doors, which could pose safety hazards and cause door leaf deformation and inflexible opening. Furthermore, it allows for factory customization, improving overall installation efficiency and quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wooden door frame installation and connection structure includes a wall, a door frame, a connector, and self-tapping screws. The connector is generally L-shaped. A fixing port A is provided at halfway along the long side of the connector. The self-tapping screw passes through fixing port A and is fixedly connected to the door frame. A fixing port B and a hinge shaft adapted to fixing port B are provided at halfway along the short side of the connector. The hinge shaft passes through fixing port B and is hinged to a first fixing plate and a second fixing plate. The first fixing plate has a fixing port C, and the second fixing plate has a fixing port D. The first and second fixing plates are symmetrically arranged along the short side of the connector. A groove adapted to the short side of the connector is opened on the wall. The self-tapping screw passes through fixing port C and fixing port D respectively and is fixedly connected to the groove.

[0007] Furthermore, two sets of connectors are symmetrically arranged along the center line of the wall. The fixing point corresponding to the fixing port A is 300mm-500mm vertically from the bottom of the door frame, 300mm-500mm vertically from the top of the door frame, and 66mm-85mm horizontally from the edge of the door frame upright on the same side. The connector is made of galvanized material, with a length of 120mm-150mm in the long side direction, a length of 30mm-40mm in the short side direction, a thickness of 1mm, and a width of 15mm.

[0008] Furthermore, the first fixing piece has a length of 50mm-60mm, a thickness of 1mm, and a width of 15mm; the second fixing piece has a length of 50mm-60mm, a thickness of 1mm, and a width of 15mm.

[0009] Furthermore, the fixing port C and fixing port D are located at 1 / 2 of the first fixing piece and the second fixing piece, respectively.

[0010] Furthermore, the groove is provided with a plastic expansion bolt adapted to the self-tapping screw. The groove is 5mm-10mm deep, 60mm wide in the horizontal direction and 60mm long in the vertical direction along the wall.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, by setting up connectors, the traditional method of temporary fixing with wooden blocks and self-tapping screws is replaced, eliminating multiple steps such as temporary fixing, waiting for foam to solidify, and removing temporary fixing components, simplifying the installation process and significantly improving installation efficiency and connection strength.

[0013] 2. In this utility model, the door frame is fixed by two methods: fixing with connectors and solidifying with expanding foam. This fundamentally solves the problem of easy loosening of the door frame when fixed with expanding foam alone, ensuring the long-term stability of the door frame and effectively preventing the door leaf from shifting, deforming, and becoming inflexible when opening.

[0014] 3. In this utility model, the first and second fixing plates on the short side of the connector are connected by a hinge shaft, which gives it a certain degree of angular adaptability. During installation, after the connector is fixed on the door frame, the leveling and straightening process of the door frame can be more convenient and stable by adjusting the position of the fixing plates in the groove and by using the fine adjustment capability of the hinge shaft. This method is more efficient than the traditional method that relies on wooden wedges.

[0015] 4. In this utility model, the connectors can be prefabricated in the factory, which improves the overall installation quality and efficiency. Attached Figure Description

[0026] like Figure 1-4 As shown, a wooden door frame installation and connection structure includes a wall 1, a door frame 2, a connector 3, and self-tapping screws 4. The connector 3 is generally L-shaped. A fixing port A31 is provided at 1 / 2 of the long side of the connector 3. The self-tapping screws 4 pass through the fixing port A31 and are fixedly connected to the door frame 2. A fixing port B32 and a hinge shaft 33 adapted to the fixing port B32 are provided at 1 / 2 of the short side of the connector 3. The hinge shaft 33 passes through the fixing port B32 and is hinged to a first fixing plate 34 and a second fixing plate 35. The first fixing plate 34 has a fixing port C341, and the second fixing plate 35 has a fixing port D351. The first fixing plate 34 and the second fixing plate 35 are symmetrically arranged along the short side of the connector 3. A groove 11 adapted to the short side of the connector 3 is opened on the wall 1. The self-tapping screws 4 pass through the fixing port C341 and the fixing port D351 respectively and are fixedly connected to the groove 11.

[0027] Furthermore, two sets of connectors 3 are symmetrically arranged along the center line of the wall. The fixing point corresponding to the fixing port A31 is 300mm vertically from the bottom of the door frame, 300mm vertically from the top of the door frame, and 70mm horizontally from the edge of the door frame upright on the same side. The connector 3 is made of galvanized material, with a length of 120mm in the long side direction, a length of 30mm in the short side direction, a thickness of 1mm, and a width of 15mm.

After finally adjusting the horizontal and vertical alignment, fix the other fixing piece on each connector to the wall groove using plastic expansion bolts and self-tapping screws. Fifth, fill the gap between the door frame and the wall opening with expanding foam. Afterward, you can proceed with the subsequent work without waiting for the expanding foam to completely harden.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] In this utility model, by setting up connectors, the traditional method of temporary fixing with wooden blocks and self-tapping screws is replaced, eliminating multiple steps such as temporary fixing, waiting for the foam to solidify, and removing the temporary fixing components. This simplifies the installation process and significantly improves installation efficiency and connection strength.

[0034] In this utility model, the door frame is fixed by two methods: fixing with connectors and solidifying with expanding foam. This fundamentally solves the problem of the door frame being easy to loosen when fixed with expanding foam alone, ensuring the long-term stability of the door frame and effectively preventing the door leaf from shifting, deforming, and becoming inflexible when opening.

[0035] In this invention, the first and second fixing plates on the short side of the connector are connected by a hinge shaft, giving it a certain degree of angular adaptability. During installation, after the connector is fixed on the door frame, the leveling and straightening process of the door frame can be more convenient and stable by adjusting the position of the fixing plates in the groove and utilizing the fine-tuning capability of the hinge shaft. This method is more efficient than the traditional method that relies on wooden wedges.

[0036] In this invention, the connectors can be prefabricated in the factory, improving the overall installation quality and efficiency.
