[0021] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0022] Embodiment 1:

[0023] like Figure 1-4 As shown, the utility model is a steel door equipped with a novel locking structure, including a steel door body 5, a door lock body 2 is fixedly installed inside the steel door body 5, the door lock body 2 includes a lock button 9 arranged on one side, a fixing seat 7 is fixedly installed on one side of the door lock body 2, a movable groove 13 is provided on the upper surface of the fixing seat 7, a limiting column 10 is inserted inside the movable groove 13, two positioning holes 11 are provided on the front surface of the limiting column 10, a cavity body 16 is inlaid on the rear surface of the fixing seat 7, a second spring 18 is fixedly installed on the inner side of the cavity body 16, one end of the second spring 18 is fixedly connected to a fixing ring 19, a positioning column 20 inserted into the positioning hole 11 is fixedly installed on the inner side of the fixing ring 19, and one end of the positioning column 20 passes through the cavity body 16 and is fixedly connected to an operating block 17.

[0024] like Figure 2As shown, the lock button 9 is located inside the positioning hole 11, and the cross section of the limiting column 10 is a rectangular structure.

[0025] like Figure 4 As shown, the operation block 17 and the positioning column 20 are connected to form a T-shaped structure, and the positioning column 20 is located inside the second spring 18 .

[0026] During implementation, a limiting column 10 is provided, and its upper end is inserted and fixed on the outer side of the lock button 9. At the same time, the elastic force of the second spring 18 is used to realize that one end of the positioning column 20 connected to it through the fixing ring 19 is inserted and fixed inside the bottom positioning hole 11, thereby ensuring the fixing ability of the lock button 9 and preventing outsiders from operating the lock button 9 from outside the door. This solves the technical problem that when the door lock mechanism used for steel doors is actually used, outsiders can easily use special tools from outside the door to operate the door lock handle through the installation hole of the cat's eye door mirror 3, and then open the door, making it difficult to ensure the protection ability for indoor personnel and having poor safety.

[0027] Embodiment 2:

[0028] like Figure 1-4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: a mounting through hole 4 is opened on one side of the steel door body 5, a cat's eye door mirror 3 is arranged inside the mounting through hole 4, the outer side of the steel door body 5 is rotatably connected with the door frame 1, the inner side of the door frame 1 is fixedly installed with a limit frame 6, the limit frame 6 is a U-shaped structure, a slide groove 14 is opened on the inner side of the movable groove 13, a slider 15 slidably connected to the slide groove 14 is fixedly installed on one side of the limit column 10, a first spring 12 is fixedly installed on the lower surface of the slider 15, and the lower end of the first spring 12 is fixedly connected to the fixed seat 7.

[0029] During implementation, the limit column 10 and the fixed seat 7 are movably connected by a slider 15 and a slide groove 14. The elastic force of the first spring 12 is used to control the limit column 10 connected by the slider 15 to be inserted and fixed on the outer side of the lock button 9, thereby improving the convenience of fixing the lock button 9 and enhancing practicality.

[0030] The original position of the upper end of the limiting column 10 in the present technical solution is a state away from the lock button 9. When in use, in order to improve the safety of the door lock body 2 after closing, the lock button 9 is first rotated to a vertical state so that the handle on the door lock body 2 is locked, and then the operating block 17 is pulled to drive the fixing ring 19 connected to it through the positioning column 20 to compress the second spring 18, and at the same time, one end of the positioning column 20 is separated from the interior of the upper positioning hole 11. At this time, under the elastic force of the first spring 12, the limiting column 10 connected through the slider 15 is pushed upward, so that the lock button 9 is located in the card slot 8 opened by the limiting column 10. Finally, the operating block 17 is released, and at the same time, the elastic force of the second spring 18 is used to make one end of the positioning column 20 connected to it through the fixing ring 19 inserted and fixed in the interior of the bottom positioning hole 11, so that the limiting column 10 is fixed, thereby ensuring the ability to fix the lock button 9.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
