On the first hand, the door frame collision angle structure and the door frame of the utility model comprise a top frame and two side frames, wherein the top frame and the side frames are both in groove-shaped structures;

a right-angle connecting block and a leveling angle block are arranged at the collision angle of the top frame and the side frame;

the leveling angle block is bonded on an inner side wall of the meeting angle of the top frame and the side frame;

the right angle connecting block is located the meeting angle department of top frame and side frame, and a right angle limit of this right angle connecting block passes through first screw and top frame fixed connection, and another right angle limit of right angle connecting block passes through second screw and side frame fixed connection.

Furthermore, a second screw is screwed at the right angle of the right-angle connecting block, a concave part is arranged at the position of the leveling corner block corresponding to the second screw, and the second screw is tightly abutted to the concave part of the leveling corner block.

Furthermore, the collision angle of top frame and side frame still is provided with three hornblocks, three hornblocks weld on another inside wall of the collision angle department of top frame and side frame.

Further, the triangular blocks are right-angle triangular blocks.

In a second aspect, a door frame, adopt like the utility model door frame corner structure.

The utility model has the advantages of it is following:

(1) the right-angle connecting block, the top frame and the side frame are connected together by four screws, so that the installation is convenient, and the collision angle of the door frame can be well folded;

(2) leveling corner blocks are arranged at the collision corners of the door frame, and the height difference at the collision corners of the door frame can be avoided through the leveling corner blocks;

(3) the triangular plate is welded at the collision corner of the door frame, and the triangular plate can play a role in reinforcing while ensuring attractiveness.

Detailed Description

As shown in fig. 1 to 6, the door frame corner collision structure comprises a top frame 1 and two side frames 6, wherein the top frame 1 and the side frames 6 are both of a groove-shaped structure. The collision angle between the top frame 1 and the side frame 6 is provided with a right angle connecting block 2 and a leveling angle block 5. The leveling corner block 5 is bonded on an inner side wall at the collision corner of the top frame 1 and the side frame 6. The right angle connecting block 2 is located in the collision angle positions of the top frame 1 and the side frame 6, a right angle edge of the right angle connecting block 2 is fixedly connected with the top frame 1 through two first screws 7, and the other right angle edge of the right angle connecting block 2 is fixedly connected with the side frame 6 through two first screws 7. In the present embodiment, the number of the first screws 7 may be increased or decreased as appropriate according to the actual situation.

As shown in fig. 1, 2 and 5, in the present embodiment, a second screw 4 is screwed to the right angle of the right angle connection block 2, a concave portion 5a is provided at a position of the leveling angle block 5 corresponding to the second screw 4, and an end of the second screw 4 abuts against the concave portion 5a of the leveling angle block 5.

As shown in fig. 1 and 2, in this embodiment, a triangular block 3 is further disposed at a meeting angle between the top frame 1 and the side frame 6, and the triangular block 3 is welded on the other inner side wall at the meeting angle between the top frame 1 and the side frame 6.

As shown in fig. 1, in the present embodiment, the triangular block 3 is a right-angle triangular block.

In this embodiment, the assembly process of the door frame corner structure is as follows:

step 1, applying black glue on a leveling corner block 5, and then placing the leveling corner block on an inner side wall at a corner collision position of a top frame 1 and a side frame 6;

step 2, screwing a second screw 4 (such as an M5X 25 hexagon socket head cap screw) into a right angle of the right angle connecting block 2 (at the moment, only screwing a part of the right angle connecting block 2), and then preliminarily connecting the right angle connecting block 2, the top frame 1 and the side frame 6 together by four first screws 7 (such as M6X 16 hexagon socket head cap screws);

step 3, turning over the door frame, screwing the first screw 7, leveling the collision angle by using a wood hammer, screwing the second screw 4 until the end part of the second screw 4 abuts against the concave part 5a of the leveling angle block 5, and screwing;

and 4, turning over the door frame again, putting the triangular block 3, welding the triangular block 3 on the other inner side wall at the collision angle between the top frame 1 and the side frame 6 (the inner side wall is opposite to the inner side wall in the step 1), and polishing the craters.

In this embodiment, a door frame adopts the door frame corner structure described in this embodiment.
