Description

Technical Field

[0001] The utility model relates to the technical field of profiles, in particular to a hidden hinged profile component and a building using the component. Background Art

[0002] The door and window sashes and door and window frames used in buildings or vehicles are mostly made of profiles. The door and window sashes and door and window frames are mostly connected by hinges. During installation, it is necessary to drill holes on the two profiles at the connection between the door and window sashes and the door and window frames, and then use screws to fix the two components of the hinge to the door and window sashes and the door and window frames respectively. Finally, the hinge components on the door and window sashes are assembled to the hinge components on the door and window frames to complete the installation of the doors and windows.

[0003] This door and window installation method requires steps such as drilling holes, installing hinge components on the door and window sashes and door and window frames respectively, and assembling the hinge components on the door and window sashes to the door and window frames. Disassembly and assembly are relatively troublesome and work efficiency is low.

[0004] Based on the above problems, we have developed a hidden hinged profile assembly. The two profiles that constitute the profile assembly can achieve a detachable rotation connection, which can replace the traditional hinge connection. There is no need to punch holes during installation, which improves the efficiency of disassembly and assembly. Summary of the Invention

[0005] The purpose of the present invention is to provide a hidden hinged profile assembly to solve the above problems, so as to realize a detachable rotation connection between two profiles and replace the traditional hinge connection method.

[0006] To achieve the above-mentioned objectives, the present utility model discloses a hidden hinged profile assembly, which includes a first profile and a second profile, and is characterized in that the first profile is provided with a transition cavity extending along its length, and the second profile is provided with a transition portion extending along its length, and the transition portion on the second profile can be inserted into the transition cavity on the first profile, thereby enabling the second profile and the first profile to rotate relative to each other. After adopting the above-mentioned structure, after the transition portion on the second profile is inserted into the transition cavity on the first profile, the first profile and the second profile are hinged in a hidden manner, and the first profile and the second profile can rotate relative to each other, thereby replacing traditional hinges, and no drilling is required for installation, thereby improving disassembly and assembly efficiency.

[0007] Furthermore, the first profile comprises a first profile body, which is provided with an arcuate trough. A transfer shaft is provided on the side opposite the inner concave surface of the arcuate trough. The transfer shaft is connected to the first profile body via a connecting portion. The arcuate trough, connecting portion, and transfer shaft together form the transfer cavity. The second profile comprises a second profile body, and the transfer portion is a curved plate connected to the second profile body. With this structure, the transfer cavity is formed by integrating the arcuate trough, connecting portion, and transfer shaft, while the transfer portion is simplified to a curved plate structure directly attached to the second profile body. This improvement greatly simplifies the overall design complexity of the profile.

[0008] Furthermore, the arc-shaped trough body has a first limiting surface at one side away from the connecting part, the connecting part has a second limiting surface on the side outside the transfer cavity, and the transfer shaft has a partially defective avoidance surface on the side outside the transfer cavity; the transfer part can be inserted into the transfer cavity to enable the second profile to rotate relative to the first profile within the range of a first angle α and a second angle β, and the first angle α is smaller than the second angle β; when the second profile rotates to the second angle β relative to the first profile, the first limiting surface abuts against the back side of the second profile body; when the second profile rotates to the first angle α relative to the first profile, the second limiting surface abuts against the front side of the second profile body; when the second profile rotates to the third angle γ relative to the first profile, the free end of the transfer part can escape from the transfer cavity from the opening between the avoidance surface and the inner concave surface of the arc-shaped trough body, and the third angle γ is greater than the first angle α and smaller than the second angle β. After adopting the above structure, the first profile and the second profile can move within the range of the first angle α to the second angle β; when the relative angle between the first profile and the second profile is less than the third angle γ, the first profile and the second profile can be directly matched and separated; the first profile and the second profile can rotate freely between the third angle γ and the second angle β without falling off, and are limited when turning to the second angle β.

[0009] Furthermore, the first angle α is 60 degrees, the second angle β is 180 degrees, and the third angle γ is 90 degrees. With the above structure, the first profile and the second profile can rotate freely between 90 and 180 degrees without falling off. When the utility model is used to manufacture doors and windows, the doors and windows can have a 90-degree opening range. When the relative angle between the first profile and the second profile is less than 90 degrees, the doors and windows can be easily disassembled or assembled, providing great convenience for users.

[0010] Furthermore, the first profile body has a first cavity extending along its length. With the above structure, the first cavity is beneficial to reducing the weight of the profile and saving materials.

[0011] Furthermore, the first profile body includes an upper plate and a lower plate, which respectively form the upper and lower walls of the first cavity. The arcuate trough is an arc-shaped structure with an inner concave surface facing upward. The left side of the arcuate trough forms a portion of the right wall of the first cavity. The upper side edge of the left side of the arcuate trough is connected to the right side edge of the upper plate and is connected to the connecting portion at this point. With this structure, the left side of the arcuate trough forms a portion of the right wall of the first cavity, achieving dual functions, saving materials and simplifying the design.

[0012] Furthermore, a first mounting groove, facing downward and with an inward-retracting opening, is provided on the left side of the first cavity of the first profile body. With this structure, the first mounting groove can be used to install connectors or other materials. The middle portion of the arcuate groove is connected to the right side of the lower plate, where it is connected to a side strip extending downward. With this structure, the side strip can be used to position connecting components.

[0013] Furthermore, the second profile body has a second cavity extending along its length. With the above structure, the second cavity is beneficial to reducing the weight of the profile and saving materials.

[0014] Furthermore, the lower wall of the second cavity is a flat plate, and the left and right sides of the plate extend beyond the left and right side walls of the second cavity, respectively. When the front of the second profile body faces upward, the left side of the lower wall of the second cavity is connected to the right side of the adapter portion. The adapter portion is an arc-shaped structure with its inner concave surface facing upward. The portion of the second profile body located above the second cavity is provided with a second mounting groove facing upward and with an inward-concave opening. With this structure, the second mounting groove can be used to install connectors or embed other materials.

[0015] The utility model also discloses a building comprising the aforementioned concealed hinged profile assembly, which forms a connecting portion of a door or window of the building. With the use of the concealed hinged profile assembly, the building's doors and windows no longer require hinges or drilling for installation, resulting in more efficient assembly and disassembly. The absence of visible hinges also enhances the appearance of the building.

[0016] To sum up, the beneficial effects of the present invention are that the hidden hinged profile assembly in the present invention can be used to make doors and windows, or used as building components, vehicle components and industrial profiles. After the first profile and the second profile are combined, the first profile and the second profile are hinged in a hidden manner. The first profile and the second profile can rotate relative to each other to replace traditional hinges, and no drilling is required for installation, thereby improving the efficiency of disassembly and assembly.
