[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the embodiments, by Figures 1-4 Provided is a safety warning device for electrical equipment. This utility model includes an L-shaped connecting piece 1, a spring 2 fixedly installed on one side of the L-shaped connecting piece 1, a sliding ring 3 fixedly connected to the other end of the spring 2 and slidably connected to the side wall of the L-shaped connecting piece 1, a pressure sensor 4 fixedly connected to the other end of the sliding ring 3, a sliding sleeve 5 fixedly installed on the outer side of the L-shaped connecting piece 1, an L-shaped tightening piece 6 slidably connected to the inner side of the sliding sleeve 5, a locking pin 7 fixedly installed on the outer side of the sliding sleeve 5 extending to its inner side and contacting the L-shaped tightening piece 6, a connecting tube 8 fixedly connected to the inner side of the sliding ring 3 extending to the outer side of the L-shaped connecting piece 1, and an alarm device 9 linked to the pressure sensor 4 connected to the other end of the connecting tube 8.

[0027] Furthermore, the outer side of the L-shaped tightening piece 6 is coated with a safety warning label, which is positioned towards the bending point.

[0028] Furthermore, a sliding groove is provided on the inner side of the L-shaped connecting piece 1, and a limiting block extending into the sliding groove is fixedly installed on the outside of the sliding ring 3.

[0029] Furthermore, the alarm device 9 includes an alarm sleeve 91 connected to the connecting pipe 8. A buzzer 92 extending into the bottom of the alarm sleeve 91 is fixedly installed. A resilient contact 93 is fixedly installed at one end of the buzzer 92 inside the alarm sleeve 91. A power supply controller 94 is fixedly installed inside the alarm sleeve 91. An insulating plug-in piece 95 extending between the power supply controller 94 and the resilient contact 93 is inserted into the outside of the alarm sleeve 91.

[0030] The power supply controller 94 consists of a controller and a battery. The controller is connected to the battery and the pressure sensor 4. When the pressure of the pressure sensor 4 changes, the controller controls the battery to supply power. The battery is designed to be replaceable.

[0031] Furthermore, the power supply controller 94 is connected to the pressure sensor 4, and the power supply controller 94 is externally provided with power supply contacts whose positions correspond to the positions of the elastic contacts 93.

[0032] Furthermore, when the pressure of pressure sensor 4 changes, it triggers the power supply controller 94 to operate.

[0033] Under normal conditions, the alarm device 9 is isolated from the elastic contact 93 and the power supply contact by the insulating plug 95. At this time, the two are disconnected and power supply cannot be formed, so the buzzer 92 cannot work. When the insulating plug 95 is removed, the elastic contact 93 and the power supply contact are connected, and the pressure sensor 4 can determine whether to work.

[0034] When the pressure at pressure sensor 4 is constant, power controller 94 remains in a non-powered state and the buzzer does not work.

[0035] When the pressure at pressure sensor 4 changes, the power supply controller 94 switches to power supply mode, and the buzzer starts working.

[0036] Working principle:

[0037] When a warning device is required for the power supply part, the locking pin 7 can be loosened and the distance between the L-shaped connecting piece 1 and the longitudinal section of the L-shaped tightening piece 6 can be adjusted according to the width of the power supply equipment. When the width of the power supply equipment is greater than the distance between the longitudinal section of the L-shaped tightening piece 6 and the pressure sensor 4, the locking pin 7 can be locked. At this time, pressing the pressure sensor will allow the power supply equipment to be clamped by the device.

[0038] After clamping, the pressure at pressure sensor 4 becomes stable. At this point, the insulating connector 95 can be pulled out, so that the pressure at pressure sensor 4 is the initial pressure. At the same time, the pressure is constant. When the pressure changes, i.e. when someone is about to remove the device, the pressure changes, thereby controlling the buzzer 92 to start sounding an alarm to remind maintenance personnel.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
