Description

Technical Field

[0001] The utility model relates to the technical field of safety locking devices, in particular to a safety locking device for electrical automation equipment. Background Art

[0002] The safety locking device of electrical automation equipment is also called an emergency stop device or a safety switch. Its main function is to ensure the personal safety of employees when operating or maintaining equipment. The general design principle of the device is that if an emergency occurs, the power source can be quickly cut off to prevent the operation of the equipment from causing personal injury or damage to the equipment. Patent No.: CN220434503U discloses a safety locking device for electrical automation equipment, including a door panel, and a turntable is provided on both sides of the door panel. In response to the above patent, the turntable is set at the front and rear ends of the door panel. Although locking is achieved, it also causes the door panel to be too wide. In actual use, if the door frame is wide, the door panel will not open and close normally, and thus cannot be used. Therefore, we have launched a safety locking device for electrical automation equipment. Utility Model Content

[0003] The main purpose of the utility model is to provide a safety locking device for electrical automation equipment, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A safety locking device for electric automation equipment comprises a door panel and a locking mechanism, wherein the locking mechanism is arranged in the door panel, a door frame is arranged at the front end of the door panel, and the locking mechanism is located between the door panel and the door frame.

[0006] Preferably, the locking mechanism includes a limit piece, the limit piece is a structure that is wide at the front and narrow at the back, the front end and the rear end of the limit piece are both arc-surface structures, a plurality of anti-collision strips are fixedly connected to the front end of the limit piece, a counterweight block is fixedly connected inside the limit piece, the counterweight block is located at the front position inside the limit piece, a connecting shaft is inserted and fixedly connected to the middle of the right end of the limit piece, a main handle is fixedly connected to the rear of the right end of the limit piece, an anti-collision gasket is fixedly connected to the left part of the outer surface of the main handle, a No. 2 anti-slip cover is fixedly connected to the right part of the outer surface of the main handle, an extension handle is fixedly connected to the middle of the outer surface of the main handle, the extension handle passes through the No. 2 anti-slip cover, and the outer surface of the extension handle is fixedly connected to the No. 1 anti-slip cover.

[0007] Preferably, a groove is formed at the rear end of the door frame.

[0008] Preferably, a cavity is opened in the door panel, a slide groove is opened at the front end of the door panel, and circular grooves are opened on the front inner wall and the rear inner wall of the cavity, and the positions of the two circular grooves correspond to each other.

[0009] Preferably, the slide groove is communicated with the cavity.

[0010] Preferably, the connecting shaft is movably connected to the two circular grooves through insertion, the main handle is slidably connected to the sliding groove, and the limiting member extends out of the cavity.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting the locking mechanism in the door panel, the main handle is pressed down to slide in the slide groove, so that the main handle drives the limiter to adjust the angle. At this time, the limiter is retracted into the door panel, the lock of the door panel is released, and the door panel can be opened and closed, thereby avoiding the device causing the door panel to widen and make it impossible to open and close normally;

[0013] 2. By setting a counterweight block on the locking mechanism, when the person does not operate the main handle, the limit piece adjusts its angle automatically due to the gravity of the counterweight block. Since the main handle slides in the slide groove, it is limited by the slide groove. At this time, the limit piece is in a horizontal state and enters the groove, thereby completing the locking. By setting an anti-collision gasket, the limit piece can be prevented from directly contacting and colliding with the door frame. By setting an extended handle and a main handle, it can be easier for people to operate. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A safety locking device for electric automation equipment comprises a door panel 1 and a locking mechanism 2. The locking mechanism 2 is arranged in the door panel 1. A door frame 3 is arranged at the front end of the door panel 1. The locking mechanism 2 is located between the door panel 1 and the door frame 3.

[0024] In this embodiment, the locking mechanism 2 includes a limit member 21, which is a structure that is wide at the front and narrow at the rear. The front and rear ends of the limit member 21 are both cambered structures. A plurality of anti-collision strips 29 are fixedly connected to the front end of the limit member 21, a counterweight block 28 is fixedly connected inside the limit member 21, and the counterweight block 28 is located at the front position inside the limit member 21. A connecting shaft 27 is inserted and fixedly connected to the middle of the right end of the limit member 21, and a main handle 26 is fixedly connected to the rear of the right end of the limit member 21. An anti-collision gasket 22 is fixedly connected to the left portion of the outer surface of the main handle 26, a No. 2 anti-slip sleeve 25 is fixedly connected to the right portion of the outer surface of the main handle 26, and an extension is fixedly connected to the middle of the outer surface of the main handle 26. The handle 24, the extended handle 24 passes through the No. 2 anti-slip sleeve 25, and the outer surface of the extended handle 24 is fixedly connected to the No. 1 anti-slip sleeve 23; a groove 31 is provided at the rear end of the door frame 3; a cavity 11 is provided in the door panel 1, and a slide groove 13 is provided at the front end of the door panel 1, and circular grooves 12 are provided on the front inner wall and the rear inner wall of the cavity 11, and the positions of the two circular grooves 12 correspond to each other; the slide groove 13 is communicated with the cavity 11; the connecting shaft 27 is movably connected with the two circular grooves 12, the main handle 26 is slidably connected with the slide groove 13, and the limit member 21 extends out of the cavity 11, and the extended handle 24 and the main handle 26 enable personnel to operate the limit member 21 from different directions, thereby improving convenience.

[0025] It should be noted that the utility model is a safety locking device for electrical automation equipment. During use, when the lock needs to be released, the main handle 26 is pressed down to slide in the slide groove 13, so that the main handle 26 drives the angle adjustment of the limit member 21. At this time, the limit member 21 is retracted into the door panel 1, and the lock on the door panel 1 is released, so that it can be opened and closed. When the person does not operate the main handle 26, the limit member 21 adjusts its angle by itself due to the influence of the gravity of the counterweight block 28. Since the main handle 26 slides in the slide groove 13 and is limited by the slide groove 13, the limit member 21 is in a horizontal state at this time, and the limit member 21 enters the groove 31, thereby completing the locking. By providing the anti-collision gasket 22, the limit member 21 can be prevented from directly contacting and colliding with the door frame 3. By providing the extension handle 24 and the main handle 26, it can be more convenient for people to operate.
