[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Referring to Figure 1 And Figure 2 The corner code connection structure for the door frame includes a plurality of door frames 1 and a plurality of right angle codes 2, and a plurality of limiting slots 3 are formed in the side walls on both sides of the right angle code 2.

[0022] Further, the material of the door frame 1 and the right angle code 2 is high-strength alloy material, which ensures the support strength of the assembled door frame.

[0023] As Figure 2As shown, the inner side wall of the door frame 1 is provided with a limiting mechanism; the limiting mechanism comprises a mounting sleeve 4 fixedly sleeved on the inner side wall of the door frame 1, the outer side wall of the right-angle code 2 and the inner side wall of the mounting sleeve 4 are slidably connected, a plurality of mounting grooves 5 are formed in the inner side wall of the mounting sleeve 4, a limiting box 6 is slidably connected to the inner side wall of the mounting groove 5, and the limiting box 6 and the inner side wall of the mounting groove 5 are connected by a plurality of springs 7, and the outer side wall of the limiting box 6 and the inner side wall of the limiting groove 3 are slidably connected.

[0024] Further explanation, in the limiting mechanism, the mounting sleeve 4 is slidably connected with the right-angle code 2, and the limiting box 6 is slidably connected with the limiting groove 3 under the action of the spring 7, so that the door frame 1 and the right-angle code 2 can be stably connected, when the door frame 1 is stressed, the limiting box 6 can be limited in the limiting groove 3, preventing the relative displacement of the door frame 1 and the right-angle code 2, ensuring the stability of the overall structure of the door frame, and this connection mode is also convenient for installation and disassembly, improving the construction efficiency.

[0025] As shown in Figure 2 , the door frame 1 and the mounting sleeve 4 are detachably connected by a plurality of fixing bolts 8.

[0026] Further explanation, this design is convenient for replacing or repairing the mounting sleeve 4, when the mounting sleeve 4 is damaged or needs to be adjusted, the entire door frame 1 does not need to be replaced, reducing the maintenance cost, and also facilitating the modification and upgrading of the door frame.

[0027] As shown in Figure 2 , a plurality of reinforcing bolts 9 are fixedly installed on the inner side wall of the mounting groove 5, and the spring 7 is slidably sleeved on the outer side wall of the reinforcing bolt 9.

[0028] Further explanation, the reinforcing bolt 9 can provide a guiding effect for the spring 7, so that the spring 7 remains stable during extension and contraction, avoiding the twisting or deviation of the spring 7, thereby ensuring the smooth sliding of the limiting box 6 in the mounting groove 5 and enhancing the reliability of the limiting mechanism.

[0029] As shown in Figure 2 , the two ends of the spring 7 are fixedly connected with the inner side wall of the limiting box 6 and the inner side wall of the mounting groove 5, respectively.

[0030] Further explanation, this design ensures the stable transmission of the spring force of the spring 7 to the limiting box 6, when the right-angle code 2 is inserted into the mounting sleeve 4, the spring 7 can accurately push the limiting box 6 to be clamped into the limiting groove 3; when disassembled or subjected to external force, the spring 7 can also normally play a buffering and resetting role, prolonging the service life of the spring 7 and the entire limiting mechanism.

[0031] As shown in Figure 2 and Figure 3 , a plurality of anti-skid grooves 10 are formed in the outer side wall of the limiting box 6.

[0032] Further illustrate, the anti-skid groove 10 on the outer side wall of the limiting box 6 increases the friction between the limiting box 6 and the limiting groove 3, and after the limiting box 6 is clamped into the limiting groove 3, the anti-skid groove 10 can effectively prevent the limiting box 6 from sliding in the limiting groove 3, further improving the stability of the connection between the door frame 1 and the right-angle code 2, and ensuring that the door frame structure is more firm.

[0033] As shown in Figure 1 , the number of the mounting grooves 5 is the same as that of the limiting grooves 3.

[0034] Further illustrate, the design ensures that each limiting box 6 in each mounting groove 5 can accurately correspond to one limiting groove 3, so that the limiting effect of the limiting mechanism is more comprehensive and balanced.

[0035] As shown in Figure 2 , the material of the limiting box 6 is aluminum alloy.

[0036] Further illustrate, the design makes the limiting box 6 maintain performance in different environments, prolong service life and reduce maintenance cost.

[0037] The utility model can be described by the following operation mode to explain its function principle:

[0038] Preliminary assembly: align one side of the right-angle code 2 with the opening of the mounting sleeve 4 on the door frame 1, and slowly slide the outer side wall of the right-angle code 2 along the inner side wall of the mounting sleeve 4, and pay attention to ensure that the right-angle code 2 is aligned with the mounting sleeve 4 during the process to avoid jamming or skewing.

[0039] Fix the right-angle code 2: as the right-angle code 2 goes deeper, the limiting box 6 in the mounting groove 5 in the mounting sleeve 4 gradually slides into the limiting groove 3 on the side wall of the right-angle code 2 under the elastic force of the spring 7. At this time, the anti-skid groove 10 on the outer side wall of the limiting box 6 is in close contact with the limiting groove 3, providing additional friction to enhance the stability of the connection.

[0040] Continue to push the right-angle code 2 until it is completely embedded in the mounting sleeve 4, and the multiple limiting boxes 6 are accurately matched with the corresponding limiting grooves 3 to complete the connection on one side. In the same way, connect the other door frame 1 with the other side of the right-angle code 2 to complete the preliminary construction of the door frame corner.

[0041] Mounting sleeve 4 fixation: if it is necessary to further fix the mounting sleeve 4 and the door frame 1, use the matching fixing bolt 8 to align the screw holes reserved on the door frame 1 and the mounting sleeve 4, and tighten the bolt with a tool to make them a stable whole.

[0042] Check and fine-tune: after the connection is completed, check whether the connection part of the door frame is firm and whether there is any sign of looseness between the right-angle code 2 and the door frame 1. If it is found that the connection is not tight enough, the right-angle code 2 or the matching condition of the limiting box 6 and the limiting groove 3 can be adjusted appropriately to ensure that the door frame structure is stable and reliable.

[0043] The above merely describes a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent substitutions or changes within the technical range disclosed by the present application, which should be covered within the scope of protection of the present application.
