Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switchgear, in particular to a low-voltage switchgear with anti-misoperation locking performance. Background Technique

[0002] In order to achieve the rapid assembly of low-voltage switches, existing manufacturers usually adopt a modular structure in the structural design. By selecting standard components and standard assemblies, a compact, diverse and flexible assembled cabinet-type low-voltage switch is finally obtained.

[0003] Although the above-mentioned assembled switch can be freely assembled to meet the multi-functional requirements, there are many switches on the surface of this cabinet-type assembled low-voltage switch. During the operation process, the user needs to open and close different switches. However, due to the large number of switches, in order to prevent the user from accidentally touching the switch and causing damage to the switch, the user needs to install some locking parts on the cabinet surface that can prevent the switch from rotating. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a low-voltage switchgear with anti-misoperation locking performance, which solves the problem that a large number of switches on the cabinet surface are likely to cause the user to accidentally touch the switch.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A low-voltage switchgear with anti-misoperation locking performance includes a group cabinet internally fixedly connected with multiple groups of low-voltage switch devices. A switch is rotatably connected to the surface of the group cabinet. An installation plate is fixedly connected to the surface of the group cabinet on one side of the switch. A plug cylinder that restricts the rotation of the switch is slidably connected to the installation plate. A first spring is arranged between the plug cylinder and the installation plate. A positioning cylinder that restricts the sliding of the plug cylinder is fixedly connected to the side wall of the installation plate.

[0006] Preferably, a plurality of sliding holes are formed on the surface of the installation plate. The installation plate is slidably connected to the plug cylinder through the sliding holes. A plurality of slots are formed on the side wall of the plug cylinder. The plug cylinder can be clamped to the switch through the slots. A jack is formed on the side wall of the plug cylinder.

[0007] Preferably, both ends of the first spring are respectively abutted against the installation plate and the inner wall of the plug cylinder.

[0008] Preferably, the positioning cylinder includes an outer cylinder fixedly installed on the side wall of the installation plate. A plug rod is slidably connected inside the outer cylinder. A second spring sleeved on the plug rod is arranged inside the outer cylinder. The end of the plug rod can be inserted into the jack.

[0009] Preferably, both ends of the second spring are respectively abutted against the inner wall of the outer cylinder and the side wall of the plug rod.

[0010] Preferably, a receiving groove is formed on the plug rod, and a rotating rod is rotatably connected to the inner wall of the receiving groove.

[0011] Beneficial effects

[0012] The utility model provides a low-voltage switchgear with anti-misoperation interlocking performance. Compared with the prior art, it has the following beneficial effects:

[0013] (1) For the low-voltage switchgear with anti-misoperation interlocking performance, by setting an insertion cylinder, a spring and a positioning cylinder, after the user rotates the switch to a proper position, the user can press the insertion cylinder downward, and the insertion cylinder will be inserted into the switch. At this time, the insertion cylinder will restrict the rotation of the switch, and at the same time, the positioning cylinder will restrict the displacement of the insertion cylinder, so that the insertion cylinder is stably inserted around the switch, thereby effectively preventing the user from accidentally touching the switch and causing the switch to displace.

[0014] (2) For the low-voltage switchgear with anti-misoperation interlocking performance, by setting the positioning cylinder, the second spring can provide a thrust for the insertion rod, so that the end of the insertion rod is stably inserted into the insertion hole. At this time, the insertion rod will restrict the insertion cylinder from sliding again, effectively ensuring that the insertion cylinder is inserted into the switch to restrict the rotation of the switch.

[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0022] Please refer toFigures 1-5 , the present utility model provides a technical solution: a low-voltage switchgear with anti-misoperation interlocking performance, including a group cabinet 1 internally fixedly connected with multiple groups of low-voltage switches. A switch 2 is rotatably connected to the surface of the group cabinet 1. A mounting plate 3 is fixedly connected to the surface of the group cabinet 1 on one side of the switch 2. A socket cylinder 4 that restricts the rotation of the switch 2 is slidably connected to the mounting plate 3. A first spring 5 is arranged between the socket cylinder 4 and the mounting plate 3. Both ends of the first spring 5 are in contact with the inner wall of the mounting plate 3 and the socket cylinder 4 respectively. The first spring 5 enables the socket cylinder 4 to be pushed outwards, effectively preventing the socket cylinder 4 from contacting the switch 2 without external force and avoiding the socket cylinder 4 from affecting the user's rotation of the switch 2. A positioning cylinder 6 that restricts the sliding of the socket cylinder 4 is fixedly connected to the side wall of the mounting plate 3. After the socket cylinder 4 moves downwards and is inserted into the switch 2, the positioning cylinder 6 can be inserted into the socket cylinder 4 to restrict the displacement of the socket cylinder 4, so that the socket cylinder 4 is stably inserted into the switch 2.

[0023] A plurality of sliding holes are formed on the surface of the mounting plate 3. The mounting plate 3 is slidably connected to the socket cylinder 4 through the sliding holes. A plurality of slots 41 are formed on the side wall of the socket cylinder 4. The socket cylinder 4 can be clamped to the switch 2 through the slots 41. A jack 42 is formed on the side wall of the socket cylinder 4.

[0024] After the user presses down the socket cylinder 4 and compresses the first spring 5, the slot 41 of the socket cylinder 4 will be clamped to the switch 2, and then the end of the positioning cylinder 6 will be inserted into the jack 42 to restrict the socket cylinder 4 from sliding again, facilitating the socket cylinder 4 to restrict the rotation of the switch 2.

[0025] The positioning cylinder 6 includes an outer cylinder 61 fixedly installed on the side wall of the mounting plate 3. A plug rod 62 is slidably connected inside the outer cylinder 61. A second spring 63 sleeved on the plug rod 62 is arranged inside the outer cylinder 61. Both ends of the second spring 63 are in contact with the inner wall of the outer cylinder 61 and the side wall of the plug rod 62 respectively. The second spring 63 can provide a thrust for the plug rod 62. After the plug rod 62 receives the thrust, the end of the plug rod 62 will be inserted into the jack 42.

[0026] When the user pulls out the plug rod 62 outwards so that the plug rod 62 disengages from the jack 42, the plug rod 62 will compress the second spring 63. To prevent the second spring 63 from providing a thrust for the plug rod 62 and causing the plug rod 62 to return to the inside of the outer cylinder 61 again, a receiving groove is formed on the plug rod 62, and a rotating rod 64 is rotatably connected to the inner wall of the receiving groove. The user can rotate the rotating rod 64. After the rotating rod 64 is perpendicular to the outer cylinder 61, it will be clamped to the end of the outer cylinder 61, thereby restricting the plug rod 62 from being inserted back into the outer cylinder 61, effectively preventing the plug rod 62 from being inserted into the jack 42. At this time, the reset of the first spring 5 will drive the socket cylinder 4 to disengage from the switch 2, facilitating the user to rotate the switch 2.

[0027] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0028] When the user needs to restrict the rotation of the switch 2, the user can pull out the insertion rod 62 outward and compress the second spring 63, then press the insertion cylinder 4 inward so that the slot 41 is clamped on the switch 2, and then release the insertion rod 62. The insertion rod 62 is inserted into the insertion hole 42 under the action of the second spring 63. At this time, the insertion rod 62 can restrict the displacement of the insertion cylinder 4, facilitating the stable clamping of the insertion cylinder 4 on the switch 2, thereby effectively preventing the user from accidentally touching and rotating the switch 2. The above is the working principle of a low-voltage switch device with anti-misoperation and anti-locking performance.
