Description

Technical Field

[0001] This utility model belongs to the field of door frame technology, specifically relating to a door frame and its gate that can be installed quickly. Background Technology

[0002] The main gate is mainly composed of a door frame and door leaves. The door leaves are the main components of the gate, serving to isolate space and prevent theft. The door frame is a component fixed to the wall and used to connect the door leaves and the wall. The door frame mainly includes a side frame and a cross frame, with the two ends of the cross frame connected to the side frame.

[0003] In existing technologies, the connection between the horizontal frame and the side frame is mostly integrated, with the joint featuring an angled corner structure to facilitate the connection. The connection primarily employs full welding to secure the horizontal and side frames together. However, this integrated door frame is bulky, cannot be disassembled after welding, and is inconvenient for transportation, especially for large-scale shipments. Furthermore, the full welding of the horizontal and side frames involves a large amount of welding work and requires highly skilled operators, which is detrimental to the mass production of door frames.

[0004] Therefore, it is necessary to design a door frame and its gate that can be installed quickly, so as to facilitate the transportation and installation of the door frame and gate. Utility Model Content

[0005] This utility model provides a quick-installation door frame and its gate to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A quick-installation door frame includes: a horizontal frame and a side frame; both ends of the horizontal frame are connected to one end of the side frame; the length direction of the horizontal frame is perpendicular to the length direction of the side frame; the connection between the horizontal frame and the side frame is an inclined corner structure; it also includes: a connecting structure, including connecting plates, bolts, and nuts; the connecting plates are respectively disposed at the connection between the horizontal frame and the side frame; the surface of the connecting plates is perpendicular to the surface of the horizontal frame and the side frame; the length direction of the connecting plates is consistent with the length direction of the inclined side of the inclined corner of the horizontal frame; a through hole is formed on the connecting plate; the bolt passes through the two connecting plates and is threadedly connected to the nut.

[0007] As a further improvement to the technical solution, the horizontal frame and the side frame are fixedly connected by spot welding.

[0008] As a further improvement to the technical solution, the connection structure also includes support plates; the support plates are respectively disposed on the horizontal frame and the side frame; the support plates are distributed in parallel at intervals along the length direction of the horizontal frame and the side frame.

[0009] As a further improvement to the technical solution, the support plate has an L-shaped structure.

[0010] As a further improvement to the technical solution, the length of the connecting plate is less than the length of the inclined side of the inclined corner of the horizontal frame.

[0011] As a further improvement to the technical solution, the connection structure also includes a connecting piece; the connecting piece is located at the connection between the horizontal frame and the side frame; one end of the connecting piece is fixedly connected to the horizontal frame, and the other end is fixedly connected to the side frame.

[0012] As a further improvement to the technical solution, the surface of the connecting piece is parallel to the frame surfaces of the horizontal frame and the side frame.

[0013] As a further improvement to the technical solution, the connecting pieces are spot-welded for fixed connection.

[0014] This application also discloses a conveniently installed gate, including the aforementioned conveniently installed gate and door leaf; the door leaf is disposed on the door frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This application simplifies the connection between the horizontal frame and the side frame, making their installation quick and enabling modular assembly of the door frame. Only the structural modules, such as the horizontal frame, side frame, and connecting structure, need to be mass-produced and transported. Installation is then carried out by personnel working together in a coordinated manner. During installation, the inclined corners of the horizontal frame and side frame are joined together, and the connecting plates are simultaneously joined. Bolts pass through the two connecting plates and are then connected with nuts. The bolts and nuts secure the connecting plates, thus connecting the horizontal frame and the side frame. Finally, spot welding is used to connect the areas of the horizontal frame and side frame not covered by the connecting plates. This combination of connecting plates and spot welding enhances the connection stability of the horizontal frame and side frame. Spot welding has a small welding area, is simple to operate, and requires less work, effectively reducing the workload of connecting the horizontal frame and side frame. Attached Figure Description

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1: like Figures 1 to 5 As shown, a quick-installation door frame includes: a horizontal frame 1, a side frame 2, and a connecting mechanism 3; both ends of the horizontal frame 1 are connected to one end of the side frame 2; the length direction of the horizontal frame 1 is perpendicular to the length direction of the side frame 2, and the horizontal frame 1 and the side frame 2 are on the same plane; the connection between the horizontal frame 1 and the side frame 2 is an inclined corner structure that can be mated together; the connecting structure 3 includes a connecting plate 31, a bolt 32, and a nut 33; the connecting plate 31 is respectively disposed at the connection between the horizontal frame 1 and the side frame 2, and the connecting plate 31 is located on the horizontal frame 1 and the side frame 2, with the plate surface of the connecting plate 31 perpendicular to the frame surface of the horizontal frame 1 and the side frame 2; the length direction of the connecting plate 31 is consistent with the inclined direction of the inclined corner of the horizontal frame 1; the connecting plate 31 has through holes, and bolts pass through two adjacent connecting plates 31 and are connected to the nuts 33 to connect the connection between the horizontal frame 1 and the side frame 2.

[0022] Preferably, the horizontal frame 1 and the side frame 2 are fixedly connected by spot welding. Spot welding is used to weld the parts of the horizontal frame 1 and the side frame 2 that are not connected by the connecting plate 31, bolt 32 and nut 33. That is, by combining the connecting plate 31 and spot welding, the connection stability of the horizontal frame 1 and the side frame 2 is enhanced. Spot welding has a small welding area, is simple to operate, and requires less work, which can effectively reduce the amount of work required to connect the horizontal frame 1 and the side frame 2.

[0023] Work style: During installation, the inclined corners of the horizontal frame 1 and the side frame 2 are aligned, and the connecting plate 31 is aligned simultaneously. Bolts 32 pass through the two connecting plates 31 and are then connected with nuts 33. The bolts 32 and nuts secure the connecting plate 31, thereby connecting the horizontal frame 1 and the side frame 2. Finally, spot welding is used to connect the parts of the horizontal frame 1 and the side frame 2 that are not covered by the connecting plate 31. The combination of connecting plate 31 and spot welding enhances the connection stability of the horizontal frame 1 and the side frame 2. Spot welding has a small welding area, is simple to operate, and requires less work, which can effectively reduce the workload of connecting the horizontal frame 1 and the side frame 2 and simplify the connection between the horizontal frame 1 and the side frame 2. This makes the installation of the horizontal frame 1 and the side frame 2 quick, thereby realizing the modular combination of the door frame. Only the structural modules such as the horizontal frame 1, the side frame 2, and the connecting structure 3 need to be mass-produced and transported. During installation, personnel can operate and cooperate in a division of labor.

[0024] like Figures 2 to 4 As shown, preferably, the connecting structure 3 further includes a support plate 34; the support plate 34 is respectively disposed on the horizontal frame 1 and the side frame 2; the support plate 34 is distributed in parallel at intervals along the length direction of the horizontal frame 1 and the side frame 2, and the support plate 34 enhances the structural stability of the horizontal frame 1 and the side frame 2; preferably, the support plate 34 is an L-shaped structure to prevent the horizontal frame 1 and the side frame 2 from deforming.

[0025] like Figure 5 As shown, preferably, the length of the connecting plate 31 is less than the length of the inclined side of the inclined corner of the horizontal frame 1, so as to leave space; the connecting structure 3 also includes a connecting piece 35; the connecting piece 35 is located at the connection between the horizontal frame 1 and the side frame 2, that is, the connecting piece 35 is located in the space left by the connecting plate 31; one end of the connecting piece 35 is fixedly connected to the horizontal frame 1, and the other end is fixedly connected to the side frame 2. Preferably, the connecting piece 35 is fixedly connected to the horizontal frame 1 and the side frame 2 by spot welding, and the two ends of the connecting piece 35 are respectively connected to the horizontal frame 1 and the side frame 2, thereby strengthening the connection between the horizontal frame 1 and the side frame 2.

[0026] Example 2: A quick-installation gate includes a quick-installation door frame and a door leaf 4 as described in Embodiment 1. The door leaf 4 is mounted on the door frame to form the gate. During transportation, the door leaf 4 is separated from the door frame. During installation, the door leaf 4 is then installed onto the door frame, facilitating the large-scale transportation of the door frame and door leaf 4. It should be noted that the connection method between the door leaf and the door frame is a conventional connection, which remains unchanged in this application. The structure of the door frame does not affect the connection with the door leaf. In reality, door frames and door leaves are also transported separately, and during installation, the door frame is typically installed first, followed by the door leaf; therefore, further details will not be elaborated upon here.

[0027] In addition, it should be emphasized that this application mainly targets the rapid installation of door frames and doors. After the door frames are pre-produced and transported, they are then installed by operators in a suitable installation environment. The installation method is simple, and those skilled in the art can fine-tune the installation operation according to the actual situation. As for other unforeseen or unexpected extreme situations, they are not the technical problems to be solved by this application, nor are they the scenarios used in this application.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
