[0024] As a technical optimization solution of the utility model, by setting a clamping mechanism 9, the first frame 1 and the second frame 4 can be connected, avoiding the use of bolts to connect the door frame, resulting in slow installation speed and low efficiency, and improving the use efficiency of the connection structure.

[0025] refer to Figure 3 A first weight-reducing groove 10 is opened on the left side of the first clamping block 3 , and the first weight-reducing groove 10 is located inside the first frame body 1 .

[0026] As a technical optimization solution of the utility model, by providing the first weight-reducing groove 10 , the weight of the first clamping block 3 can be reduced, avoiding the large amount of processing materials for the first clamping block 3 , which leads to increased costs, and reducing the production cost of the first clamping block 3 .

[0027] refer to Figure 4 The inner side of the top of the block 95 is designed with a rounded corner 11, and the rounded corner 11 is located at the bottom of the fixing column 91.

[0028] As a technical optimization solution of the present invention, by setting the rounded corners 11, it is possible to facilitate the movement of the card block 95, avoid the card block 95 from getting stuck during movement, resulting in the card block 95 being unable to be clamped normally, and improve the use stability of the card block 95.

[0034] As a technical optimization solution of the utility model, by setting the second weight-reducing groove 14, the weight of the second clamping block 6 can be reduced, avoiding excessive material consumption during processing, which leads to high processing cost of the second clamping block 6, and reducing the processing cost of the second clamping block 6.

[0035] The working principle and use process of the utility model are as follows: when in use, when the door frame needs to be assembled, first move the second frame body 4, the second positioning plate 5 and the second clamping block 6 to the left, insert the plug-in plate 8 into the interior of the mounting plate 7, and when the plug-in plate 8 is inserted into the mounting plate 7, move the second frame body 4, the second positioning plate 5 and the second clamping block 6 downward, insert the fixing column 91 into the clamping groove 96, and the clamping groove 96 squeezes the clamping block 95 to shrink inward, and the clamping block 95 compresses the spring 94. When the clamping groove 96 releases the limit on the clamping block 95, the elastic force of the spring 94 pushes the clamping block 95 to expand outward, and the clamping block 95 is clamped in the interior of the clamping groove 96, and the first frame body 1 and the second frame body 4 can be connected, thereby having the advantage of efficient connection.

[0036] To sum up: the plastic door frame connection structure, through the coordinated use of the first frame 1, the first positioning plate 2, the first clamping block 3, the second frame 4, the second positioning plate 5, the second clamping block 6, the mounting plate 7, the plug-in plate 8 and the clamping mechanism 9, solves the problem that the door frame needs to use the connection structure to connect the frame during installation. The frame is generally disassembled and repacked during transportation, so that it occupies less space and is convenient for transportation. The frame is only connected when the door frame needs to be installed. The existing door frame frame is generally connected using bolts, and professional tools are required for installation. The installation time is long, which reduces the connection efficiency of the door frame.
