[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a steel door adjustable hinge lining, including a lining body 1, a door leaf 2, a hinge hole 3, a fixing pin 4, a bending end 401, a limiting end 402, a spring sheet 5, a groove 6, a latch 7, a fixing block 8, a stopper 9 and a fixing hole 10;

[0021] The new hinge adjustable technology is divided into two parts: the hinge lining plate body 1 and the steel door leaf 2. The lining plate body 1 is cut and punched with a 3mm steel plate on a punch press, and then the hinge installation hole is tapped to make the fixing hole 10 on the lining plate body 1 and the hinge hole 3 on the side of the door leaf 2 have the same diameter. The lining plate body 1 is aligned with the side of the door leaf 2. According to the height of the door leaf 2 and the door frame, the fixing hole 10 on the lining plate body 1 is aligned with the hinge hole 3 on the side of the door leaf 2 at the required height, and then the fixing pin 4 is passed through the alignment. The hinge hole 3 and the fixing hole 10 are aligned, and then the fixing needle 4 includes a bent end 401 and a limiting end 402. The limiting end 402 enters the door leaf 2. Since the upper and lower side walls in the fixing hole 10 are fixedly installed with spring sheets 5, the limiting end 402 contacts the spring sheet 5 to generate friction, so that the limiting end 402 is limited. Then, the bent end 401 is bent to fit the lining plate body 1 by hand or with a simple tool, so that the fixing needle 4 can more firmly limit the lining plate body 1 and the door leaf 2.

[0022] Since a groove 6 is provided in the middle of the left side of the front end of the lining plate body 1, a latch 7 is fixedly connected to the upper wall of the groove 6, and a fixing block 8 is rotatably connected to the outer end of the latch 7, and a blocking rod 9 is fixedly connected to the lower end of the fixing block 8. Therefore, after the door leaf 2 is opened, the blocking rod 9 is rotated and lifted to block the side of the door leaf 2. When the wind blows, the blocking rod 9 resists the door leaf, so that the door leaf 2 is not easily blown by the wind. When the fixing block 8 rotates, the friction force generated with the latch 7 is large, making the blocking rod 9 difficult to rotate. When the lining plate body 1 is disassembled, the fixing pin 4 is straightened, and then the bent end 401 is pulled outward. Since the spring sheet 5 and the moving limiting end 402 generate friction, the limiting end 402 is pulled out.

[0023] The above is to complete a series of operations of the adjustable hinge lining of the steel door. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
