[0025] The following will be combined with the drawings in the specification 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 of 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.

[0026] Reference Figure 1 , Figure 2 and Figure 4 , the utility model provides an embodiment: a safety lock for processing steel structure of white body, including a first installation box 1, the inner outer wall of the first installation box 1 is fixedly connected to four support columns 3, one end surface of the support column 3 is fixedly connected to the fixing plate 6, a section of the inner outer wall of the first installation box 1 is fixedly connected to the motor 4, the output end of the motor 4 is fixedly connected to the rotating shaft 5, one end surface of the rotating shaft 5 is fixedly connected to the gear 7, one side of the gear 7 is meshed and connected to the rack 10, one end surface of the rack 10 is fixedly connected to the second connecting rod 13, one end surface of the second connecting rod 13 is fixedly connected to the second fixed column 14, one end surface of the second fixed column 14 is fixedly connected to the third connecting rod 16, one end surface of the third connecting rod 16 is fixedly connected to the third fixed column 17, a first slide plate 15 is arranged on one side of the third fixed column 17, the first slide plate 15 is slidably connected to the third connecting rod 16, a second installation box 2 is arranged on one side of the first installation box 1, and a self-locking component is arranged inside the second installation box 2. The motor 4 is a motor that can be remotely controlled and monitored. The motor 4 rotates to drive the rotating shaft 5 to rotate, and the gear 7 rotates accordingly, and the rack 10 matching the gear 7 can move, so the second connecting rod 13 and the third fixed column 17 move toward the second installation box 2. This setting can be controlled by the motor 4 to complete the unlocking and locking, and is not easy to be opened by outsiders.

[0027] Reference Figure 1 , Figure 3 and Figure 5The self-locking component includes a slide rod 22, a spring 21 and a second slide plate 20. The outer wall of one end of the inner part of the second installation box 2 is fixedly connected to the connecting tube 18. Two limit covers 19 are arranged on the outer wall of one end of the connecting tube 18. One end surface of the limit cover 19 is fixedly connected to the slide rod 22. One end surface of the slide rod 22 is fixedly connected to the second slide plate 20. One end surface of the second slide plate 20 is fixedly connected to the spring 21. The second slide plate 20 is slidably connected to the connecting tube 18, and the slide rod 22 is slidably connected to the connecting tube 18. The first slide plate 15 and the third fixing column 17 are both cone-shaped, which can be conveniently connected to the second slide plate 20. When the second fixing column 14 enters the second installation box 2 and the connecting tube 18, the second slide plate 20 is squeezed by the third fixing column 17 and can enter the middle of the third fixing column 17 and the first slide plate 15. Since the second slide plate 20 is a trapezoid, when the motor 4 stops, the second slide plate 20 cannot be pulled out by external force. When unlocking is required, the motor 4 rotates forward first, and the third fixing column 17 can be brought to the bottom of the first slide plate 15. Then the motor 4 reverses, which can drive the first slide plate 15 to slide up. The top area of ​​the first slide plate 15 is slightly smaller than the bottom area of ​​the third fixing column 17. Therefore, the second slide plate 20 no longer restricts the third fixing column 17, and the unlocking can be completed. This setting can make the second connecting rod 13 and the second installation box 2 more tightly connected, reducing the wear of the second connecting rod 13 on the second installation box 2 caused by the shaking of the second connecting rod 13 in the second installation box 2.

[0028] Reference Figure 2 One end surface of the fixing plate 6 is fixedly connected to two first fixing blocks 9, one end surface of the rack 10 is fixedly connected to two first connecting rods 11, and the rack 10 is slidably connected to the first fixing blocks 9. This arrangement can limit the moving distance of the rack 10.

[0029] Reference Figure 2 , one end surface of the fixing plate 6 is fixedly connected to the second fixing block 12, and the second fixing block 12 is slidably connected to the second connecting rod 13. This arrangement can make the second connecting rod 13 move more smoothly.

[0030] Reference Figure 3 and Figure 5 A hollow groove 23 is formed on the outer wall of one end of the connecting tube 18 , and one end surface of the spring 21 is fixedly connected to the outer wall of one end of the connecting tube 18 near the hollow groove 23 .

[0031] Reference Figure 4 , the first slide plate 15 is smaller than the third fixing column 17, and the bottom area of ​​the first slide plate 15 is smaller than the top area of ​​the second fixing column 14. This arrangement can ensure that the second slide plate 20 can slide in and out.

[0032] Reference Figure 2 , one end surface of the gear 7 is fixedly connected to the first fixed column 8, the gear 7 is rotatably connected to the fixed plate 6, and the rack 10 is slidably connected to the fixed plate 6. This arrangement ensures that the gear 7 runs stably.

[0033] Reference Figure 2 , the rotating shaft 5 passes through the fixed plate 6 and is connected with the gear 7.

[0034] Working principle: the motor 4 can indirectly drive the rotation of the gear 7, thereby prompting the movement of the rack 10, and the second connecting rod 13 and the third fixed column 17 can extend into the connecting tube 18, the second slide plate 20 is squeezed and retracted, the spring 21 rebounds, and the second slide plate 20 can clamp the third fixed column 17 to complete the locking. When unlocking, the forward rotation of the motor 4 can make the first slide plate 15 move the second slide plate 20 to its bottom, and then the motor 4 reverses, and the first slide plate 15 can retract the second slide plate 20, so that the third fixed column 17 withdraws, and the unlocking can be completed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
