[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The embodiment of the present application solves the technical problem that a pure wooden door frame is prone to moisture absorption and deformation by providing a door frame.
[0024] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:
[0025] The door frame provided by the embodiment of the utility model is applied to the door frame, including a wooden inner core and a wood-plastic outer shell; one end of the wood-plastic outer shell completely wraps the wooden inner core, and the other end is respectively provided with a short leg and a long leg; the short leg is used to abut against the surface of the wall, and the long leg is used to insert into the corresponding slot on the door frame. On the one hand, with the help of the excellent physical properties of wood-plastic, moisture absorption and deformation are avoided; on the other hand, by using the short leg and the long leg together, the door frame is fastened to the wall.
[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] Example:
[0028] The embodiment of the utility model provides a door frame, which is applied to a door frame and comprises a wooden inner core 1 and a wood-plastic outer shell 2.
[0029] like Figure 1 As shown, one end of the wood-plastic shell 2 completely wraps the wooden inner core 1, and the other end is provided with a short leg 21 and a long leg 22;
[0030] like Figure 2 As shown, the short leg 21 is used to abut against the surface of the wall, and the long leg 22 (i.e. the plug) is used to be inserted into the corresponding slot on the door frame.
[0031] It is not difficult to understand that the use of wooden core 1 can retain the advantages of traditional pure wooden door frame such as high hardness, stability and low cost; while the use of wood-plastic outer shell 2 can completely eliminate the defects such as moisture absorption and deformation by taking advantage of the excellent physical properties of wood-plastic materials such as environmental protection, waterproof, mildew-proof, post-processing and B1 flame retardant.
[0032] At the same time, the embodiment of the utility model uses a short leg 21 and a long leg 22 that can be set in parallel, wherein the short leg 21 can determine the specific shape according to the surface flatness of the wall, and the long leg 22 can determine the specific shape according to the corresponding slot on the door frame, which together play the role of fastening the door frame to the wall.
[0033] In particular, although the conventional co-extrusion process can achieve the complete wrapping of the wood-plastic shell 2 with the wooden inner core 1, it is considered that the contact parts of the two different materials may be separated during the subsequent use. In order to avoid or suppress the occurrence of this phenomenon, in an optional embodiment, at least one surface of the wooden inner core 1 can be set as an irregular plane to increase the contact area between the two different materials, thereby increasing the adhesion of the contact parts.
[0034] like Figures 1-2 As shown, all surfaces of the wooden core 1 in the extension direction of the door frame can be set to be serrated.
[0035] It should be noted that the wooden core 1 shown in the figure is approximately rectangular in cross section and the surface is arranged in a regular serrated shape, which is only an example. In fact, the embodiment of the utility model does not require that the wooden core 1 must be limited to this unique shape, and it should be understood that as long as the basic requirements of this application are met, those skilled in the art can design it according to their own needs.
[0036] In addition, considering that the door frame is a building profile that cooperates with the slot on the door frame to fix the door frame. In order to further improve the fastening of the door frame to the wall, in an optional embodiment, at least one surface of the long leg portion 22 can be set as an irregular plane to improve the gluing strength between the long leg portion 22 and the corresponding slot on the door frame (when in use, glue is usually poured into the slot to improve stability).
[0037] like Figures 1-2 As shown, the surface of the long leg portion 22 facing the wall can be set to be sawtooth-shaped.
[0038] It should also be noted that the long leg 22 shown in the figure is approximately rectangular in cross section to match the corresponding slot, and the surface facing the wall is set to a regular serrated shape, which is only an example. In fact, the embodiment of the utility model does not require that the long leg 22 must be limited to this unique shape, and it should be understood that as long as the basic requirements of this application are met, those skilled in the art can design it according to their own needs.
[0039] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0040] 1. The door frame provided by the embodiment of the utility model is applied to the door frame, including a wooden inner core and a wood-plastic outer shell; one end of the wood-plastic outer shell completely wraps the wooden inner core, and the other end is respectively provided with a short leg and a long leg; the short leg is used to abut against the surface of the wall, and the long leg is used to insert into the corresponding slot on the door frame. On the one hand, with the help of the excellent physical properties of wood-plastic, moisture absorption and deformation are avoided; on the other hand, by using the short leg and the long leg together, the door frame is fastened to the wall.
[0041] 2. In the embodiment of the utility model, at least one surface of the wooden inner core can be set as an irregular plane to increase the contact area between the two different materials, thereby increasing the adhesion of the contact part.
[0042] 3. In the embodiment of the utility model, at least one surface of the long leg portion can be set as an irregular plane to improve the bonding strength between the long leg portion and the corresponding slot on the door frame.
[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
