Description

Technical Field

[0001] This utility model relates to the field of equipment maintenance safety protection, specifically to a multi-person maintenance locking device. Background Technology

[0002] During equipment maintenance, to prevent accidental equipment startup from injuring maintenance personnel, the standard procedure is to de-energize and lock the power supply box. However, there is a significant deficiency: most power supply boxes only have one access keyhole, allowing only one access lock to be installed. When multiple maintenance tasks are required, if one maintenance worker removes the lock and restores power after completing their work, the equipment may start, potentially causing mechanical injury to another worker still performing maintenance. This situation seriously threatens the lives of maintenance personnel and poses a significant challenge to the safety and orderliness of maintenance work. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a multi-person maintenance lock, which aims to solve the problem of safety hazards caused by the single lock hole of the power box in the prior art when multiple people are performing maintenance.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows: A multi-person maintenance lock includes a lock body, which is S-shaped and includes a first section and a second section that are continuously transitioned by an arc. Two lock bodies are provided, and each lock body has a through hole perpendicularly opened at the transition point between its first and second sections. The two lock bodies are rotatably connected at the through holes by a pin. When the two lock bodies are closed, they form an 8-shaped closed loop structure. Multiple lock holes are provided at intervals on the free ends of the second sections of the two lock bodies, and the lock holes on the two lock bodies are positioned correspondingly.

[0005] As a further improvement of this utility model, the free ends of the first sections of the two lock bodies are fixed with lock tongues, and when the two lock bodies are closed, the two lock tongues overlap vertically.

[0006] As a further improvement of this utility model, the number of lock holes is 2-6.

[0007] As a further improvement of this utility model, the radius of the arc of the first section is smaller than the radius of the arc of the second section.

[0008] As a further improvement of this utility model, the surface of the S-shaped lock body is provided with an anti-rust coating.

[0009] The beneficial effects of this utility model are as follows: When multiple maintenance operations are carried out simultaneously on the equipment, this utility model can hang multiple maintenance locks. Only after all maintenance operations are completed and all maintenance personnel have removed all the hanging maintenance locks can the power box be opened for power supply. This fundamentally eliminates the situation where some personnel remove the locks and supply power in advance, ensuring the safety and orderliness of the maintenance process. It effectively prevents serious safety accidents caused by one maintenance personnel removing the locks and supplying power after completing their own maintenance, resulting in mechanical injuries to other maintenance personnel due to equipment startup. This provides a solid guarantee for the life safety of maintenance personnel and greatly improves the safety of equipment maintenance operations. Attached Figure Description

[0012] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0014] like Figure 1-2 As shown, a multi-person maintenance lock includes a lock body 1, which is S-shaped and includes a first section 2 and a second section 3 that are continuously transitioned by an arc. There are two lock bodies 1, and each lock body 1 has a through hole vertically opened at the transition point of its first section 2 and second section 3. The two lock bodies 1 are rotatably connected at the through hole by a pin 4. When the two lock bodies 1 are closed, they form a figure-eight closed loop structure. Multiple lock holes 5 are provided at intervals on the free ends of the second section 3 of the two lock bodies 1, and the lock holes 5 on the two lock bodies 1 are corresponding to each other.

[0015] Both lock bodies 1 have a bolt 6 fixed to the free end of the first section 2. When the two lock bodies 1 are closed, the two bolts 6 overlap vertically.

[0016] The number of keyholes 5 is 2-6.

[0017] The radius of the arc in the first section 2 is smaller than the radius of the arc in the second section 3.

[0018] The surface of the S-type lock body 1 is provided with an anti-rust coating.

[0019] The operating steps for using this utility model are as follows: 1. Pass the first section 2 of the lock body 1 through the lock hole 5 of the power supply box to fix the lock body 1 to the power supply box.

[0020] 2. When multiple people are performing maintenance, each worker will pass their maintenance lock through the corresponding keyhole 5 of the two lock bodies 1 and lock it. At this time, the lock body 1 is in a closed state and the power box cannot be opened.

[0021] 3. After all maintenance work is completed, all personnel remove their respective maintenance locks. Both lock bodies 1 can be opened by rotating pin 4 to allow power to be supplied to the power box.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, component disassembly or combination, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
