Description

A catchy and positionable joint door frame structure

Technical field:

The utility model belongs to the field of steel door frames, in particular to a spliced door frame structure with catchable openings that can be positioned.

Background technique:

In the current construction market, steel doors are more widely used in industrial, civil and other fields due to their good firmness and durability. Now the utilization rate of steel doors exceeds 80%. With the continuous improvement of processing methods, the appearance of steel doors has made great progress, especially in the door frame structure.

Existing steel door frame structures are roughly divided into two categories, one is a welded one-piece structure, and the other is an on-site splicing structure. When splicing the door frame on site, the installer needs to manually check the inner size of the door frame. If the installer makes a mistake in checking the size, there will be a size deviation, which will cause scratches on the door panel and large door gaps, which will seriously affect the quality of the door frame.

Utility model content:

The utility model overcomes the deficiencies in the prior art, solves the problems that the on-site splicing structure is prone to dimensional deviation, resulting in scratches on the door panels and large gaps in the door, and aims to provide a splicing door frame structure that can be positioned at the top. The splicing door frame The structural design is novel, and the manufacture is simple and convenient. The tenon joint and tenon joint groove are used to realize the self-positioning of the connection between the horizontal frame and the mullion.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a spliced door frame structure with a catchable opening, including a horizontal frame and two mullions connected with the horizontal frame, the cross-sectional structure of the horizontal frame and the vertical frame Similarly, a socket is provided on the side where the vertical frame is connected to the horizontal frame, and the shape of the socket is adapted to the cross-sectional shape of the horizontal frame. The socket is preset with a plurality of tenon joints, and the horizontal frame connected to the socket is preset with a tenon. The mortise and tenon joints are compatible with the joints, and the mortise joints and the tenon joints are inserted into each other to position and fix the horizontal frame and the vertical frame.

Further, fasteners are installed on the bottom surface of the socket, and the bottom surface of the horizontal frame is fixedly connected with the fasteners to connect the horizontal frame to the vertical frame.

Further, the material of the horizontal frame and the vertical frame is steel.

Compared with the prior art, the utility model has the following beneficial effects: the utility model presets the tenon joint and the tenon joint groove on the vertical frame and the horizontal frame respectively, and when installed, the tenon joint of the vertical frame is inserted into the tenon joint of the horizontal frame In the groove, the self-positioning of the mullion and the horizontal frame is completed, and there is no need to check the joint size. The installation size is accurate, and there will be no problems of door scraping and large door gaps. In addition, the plug-in positioning structure of the utility model simplifies the on-site The installation process saves on-site installation time and improves installation efficiency.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is described in further detail;

Fig. 1 is a schematic diagram of the insertion process of the horizontal frame and the vertical frame 2;

Fig. 2 is a schematic diagram of the structure after the door frame is connected.

In the figure: 1 is a horizontal frame, 2 is a vertical frame, 3 is a socket, 4 is a tenon joint, 5 is a tenon joint groove, 6 is a fastener, and 7 is a self-tapping screw.

Detailed ways:

As shown in Fig. 1-Fig. 2, a spliced door frame structure with an upper opening that can be positioned includes a horizontal frame 1 and two mullions 2 connected to the horizontal frame 1, and the cross-sectional structure of the horizontal frame 1 and the mullion 2 is the same The side where the mullion 2 is connected to the horizontal frame 1 is provided with a socket 3, the shape of the socket 3 is adapted to the cross-sectional shape of the horizontal frame 1, and a plurality of tenon joints 4 are preset at the socket 3, and the socket 3 connected The tenon joint groove 5 compatible with the tenon joint 4 is preset at the horizontal frame 1, and the tenon joint 4 and the tenon joint groove 5 are inserted into each other to position and fix the horizontal frame 1 and the vertical frame 2.

When the utility model is installed on site, the tenon joint groove 5 of the horizontal frame 1 is inserted into the tenon joint 4 of the vertical frame 2, and the tenon joint groove 5 and the tenon joint 4 realize the self-positioning of the horizontal frame 1 and the vertical frame 2, so There is no need to check the installation size, the perfect connection between the horizontal frame 1 and the vertical frame 2, the appearance is beautiful and the size is accurate. In addition, the horizontal frame 1 and the vertical frame 2 adopt the above-mentioned plug-in positioning structure, which simplifies the installation process, saves installation time, and reduces installation costs.

In order to further enhance the connection strength between the horizontal frame 1 and the vertical frame 2, the bottom surface of the socket 3 is equipped with a fastener 6, and the bottom surface of the horizontal frame 1 and the fastener 6 are fixedly connected by automatic screws to connect the horizontal frame 1 and the vertical frame. 2 connections.

In addition, the horizontal frame 1 and the vertical frame 2 constituting the door frame are made of steel. Generally, the metal door frame is made of steel, and of course the above door frame structure can also be applied to other metal and wooden door frames.

The above embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned embodiments. Make various changes below.
