[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] like Figure 1 As shown, a mechanical and electrical equipment protection device includes a first fence 1 and a second fence 2. The first fence 1 and the second fence 2 are arranged correspondingly, and the first fence 1 is hinged with a first protective door 11 and a second protective door 12 at both ends, and a magnetic locking structure 4 for magnetically locking the second protective door 12 is arranged in the middle of one end of the second fence 2, and a pressing control structure 3 for controlling the power on and off of the magnetic locking structure 4 is arranged in the middle of the other end of the second fence 2, and an extended fence 5 is arranged on one side of the first fence 1 and one side of the second fence 2.

[0022] According to the above structure, during use, when the electromechanical equipment needs to be inspected and repaired, the lock on the pressing control structure 3 is first opened. At this time, the pressing control structure 3 pops open, and the magnetic locking structure 4 is powered on to attract the second protective door 12. At this time, the second protective door 12 cannot be opened. After the safety lock is hung at one end of the pressing control structure 3, the pressing control structure 3 is pressed, the magnetic locking structure 4 is powered off, and the second protective door 12 can be opened, thereby preventing maintenance personnel from entering the electromechanical equipment area without hanging the safety lock, thereby improving the safety of maintenance personnel.

[0023] like Figure 3 As shown, the pressing control structure 3 includes a shell 31 embedded in the middle of one end of the second fence 2, an extrusion block 34 is arranged inside the shell 31, a through hole 35 is arranged on one side of the extrusion block 34, convex plates 36 are fixedly connected to both sides of the inner wall of the shell 31, and the two convex plates 36 are rotatably connected to the two ends of the through hole 35 respectively, a torsion spring 39 is arranged inside the through hole 35, one end of the torsion spring 39 is fixedly connected to one end of one of the convex plates 36, and the other end of the torsion spring 39 is fixedly connected to the side wall of the through hole 35, and a first protective door 11 is arranged on one side of the groove A groove, one end of the groove is provided with a through groove, one end of the extrusion block 34 is fixedly connected with a hanging plate 37, the hanging plate 37 passes through the through groove, and a waist-shaped groove 38 is provided on the surface of the hanging plate 37. One end of the shell 31 is fixedly connected with an end plate 32, and a strip groove 33 is provided in the middle of the end plate 32. The hanging plate 37 passes through the strip groove 33. The top of the extrusion block 34 is fixedly connected with a top block 310, and the top of the inner wall of the shell 31 is fixedly connected with a mounting block 311, and the bottom end of the mounting block 311 is fixedly connected with a light-touch normally closed switch 312 corresponding to the top block 310.

[0024] According to the above structure, after the safety lock is hung on the waist-shaped groove 38, one end of the hanging plate 37 groove rotates downward under the influence of the gravity of the safety lock, thereby driving one end of the extrusion block 34 to tilt up. At this time, the torsion spring 39 is twisted to store force. After one end of the extrusion block 34 tilts up, the top block 310 contacts the light-touch normally closed switch 312, thereby disconnecting the light-touch normally closed switch 312. When the safety lock is not on, the torsion spring 39 returns to its original state, driving the extrusion block 34 to rotate, and one end of the extrusion block 34 descends. At this time, the top block 310 separates from the light-touch normally closed switch 312, and the light-touch normally closed switch 312 is closed.

[0025] like Figure 2-4 As shown, the magnetic locking structure 4 includes a stainless steel plate 41 embedded in the middle of one end of the second fence 2 and a permanent magnet plate 43 embedded in the middle of one side of the second protective door 12. An electromagnet 42 is arranged in the middle of the stainless steel plate 41. The magnetism of the electromagnet 42 and the permanent magnet plate 43 on the side close to each other is opposite. The electromagnet 42 is electrically connected to the external power supply by lightly touching the normally closed switch 312.

[0026] According to the above structure, when the normally closed switch 312 is closed by light touch, the electromagnet 42 is energized, and the permanent magnet plate 43 is tightly attracted to one end of the permanent magnet plate 43. At this time, the second protective door 12 cannot be opened. When the normally closed switch 312 is opened by light touch, the permanent magnet plate 43 is relatively loosely adsorbed on one side of the stainless steel plate 41 by its own magnetic force. At this time, the second protective door 12 can be opened by pushing it hard.

[0027] The working principle of the utility model is as follows: during use, when it is necessary to inspect and repair the electromechanical equipment, first open the lock on the pressing control structure 3, at this time the pressing control structure 3 pops open, the magnetic locking structure 4 is powered on to attract the second protective door 12, at this time the second protective door 12 cannot be opened, after the safety lock is hung at one end of the pressing control structure 3, the pressing control structure 3 is pressed, the magnetic locking structure 4 is powered off, and the second protective door 12 can be opened, thereby preventing maintenance personnel from entering the electromechanical equipment area without hanging the safety lock, thereby improving the safety of maintenance personnel, after the safety lock is hung on the waist-shaped groove 38, under the influence of the gravity of the safety lock, one end of the hanging plate 37 groove rotates downward, thereby driving one end of the extrusion block 34 to tilt up, and at this time the torsion spring 39 is twisted Dynamically store force, after one end of the extrusion block 34 is tilted up, the top block 310 contacts the light-touch normally closed switch 312, thereby disconnecting the light-touch normally closed switch 312. When the light-touch normally closed switch 312 is disconnected, the permanent magnet plate 43 is relatively loosely adsorbed on one side of the stainless steel plate 41 by its own magnetic force. At this time, the second protective door 12 can be opened by pushing the second protective door 12 hard. When the safety lock is not on, the torsion spring 39 returns to its original state, driving the extrusion block 34 to rotate, and one end of the extrusion block 34 drops. At this time, the top block 310 is separated from the light-touch normally closed switch 312, and the light-touch normally closed switch 312 is closed. When the light-touch normally closed switch 312 is closed, the electromagnet 42 is energized to tightly attract the permanent magnet plate 43 to one end of the permanent magnet plate 43. At this time, the second protective door 12 cannot be opened.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
