Description

Combined door frame

technical field

The present invention relates to a door frame, more specifically, to a combined door frame. the

Background technique

The door frame is a frame set on the inner edge of the door hole reserved on the wall for installing and supporting the door. Due to objective reasons such as temperature, the thickness of the walls of buildings in the north and south is different, and the thickness of the walls in the north is generally thicker than that in the south. Therefore, the manufacture of the door frame can only be manufactured in a custom-made manner, which cannot realize industrialized production in large quantities. Thereby a combined door frame has appeared. When the existing combined door frame composed of inner and outer frames is installed, because it is composed of two frames, when installing, the inner and outer frames need to be fixed, and the inner and outer frames need to be fixed. To cover the gap, the existing method is to fix the inner and outer frames by the connectors installed on the back, and cover the two inner sides of the door frame by adding decorative panels. The above-mentioned combined door frame has the following disadvantages: (1) the door frame is inserted into the door frame of the wall, and the distance between the inner and outer frames cannot be adjusted. The inner frame or outer frame is not level with the wall, causing the side of the door to be higher than the wall or lower than the wall, which affects the overall appearance; (2) The connection between the decorative block and the door frame is complicated and needs to be passed through Screws or other components are connected, because they are on the surface, a decorative block must be installed outside the screw or component to ensure the overall decorative effect, making the processing and installation process complicated, and the decorative block is fixedly connected with the inner and outer frames , once the missing frame is found to be misaligned with the wall after installation, the decorative block and connector need to be removed, repositioned and then installed separately, which is very troublesome and inconvenient for subsequent maintenance and operation; (3) Since the decorative board needs to be connected with the inner and outer frames, and due to restrictions such as positioning holes, it cannot be cut according to the actual installation situation. To sum up, the existing combined door frames can't actually achieve the effect of combined door frames, and can't realize industrialized mass production and standardized production. the

In the aforementioned combined door frame, the adjusting screw is composed of a nut, a washer and a screw integrally formed sequentially, the cross section of the nut is polygonal, and a positioning groove is provided on the top surface of the nut. the

In the above combined door frame, the shape of the cross-section of the nut is a regular hexagon. the

In the above combined door frame, extensions are provided on both sides of the left connecting piece along the axial direction, and the left positioning hole is arranged on the extensions. the

In the above combined door frame, a sealing groove is provided on the surface of the frame body in contact with the door, and a sealing rubber strip is provided in the sealing groove, and the sealing rubber strips are respectively arranged on three sides of the door frame. the

After the present invention adopts the above-mentioned structure, by adding a connection plate between the inner and outer frames, the inner and outer frames and the connection plate jointly form a three-dimensional surface on the inside of the door frame, and according to the actual needs of installation, the inner and outer frames The position can be adjusted by adjusting the telescopic connector, so that the door frame can be installed on walls of various thicknesses; the inner and outer frames, connectors and panels in the present invention can realize standardized production and processing, and the connecting board can also be made into a standard wide board. In actual use, it is cut according to the distance between the inner and outer frames, so that the production of the door frame can realize large-scale industrial standardized production, which greatly reduces the production cost and use cost of the door frame; A set of adjustment holes can easily adjust the distance between the inner and outer frames, and because the connecting plate is inserted between the inner and outer frames, it can ensure that the inner and outer frames will not shift when moving, making the adjustment very convenient. It is convenient and quick, and does not require too many other operations. Furthermore, a sealing rubber strip is provided on the contact surface between the frame body and the door, so that the cooperation between the door and the door frame has the effect of sealing and sound insulation. The invention has the advantages of simple installation, easy adjustment and sealing and sound insulation. the
