Description

Technical Field

[0001] This utility model relates to the field of electrical grounding switch technology, and in particular to an electrical grounding switch locking device. Background Technology

[0002] Electrical grounding switches are crucial safety devices in power systems, used to reliably ground electrical equipment during maintenance or repair to ensure operator safety. To prevent misoperation and ensure system safety, grounding switches are typically equipped with interlocking devices. These interlocking devices achieve their interlocking function through mechanical or electrical means, ensuring that the grounding switch can only be operated under specific conditions.

[0003] However, in the existing technology, most electrical grounding switch locking devices are linked to the electrical cabinet door. When the door is opened, the locking device is activated. When the door is subjected to external force, the locking device is easily reset, which poses a certain safety hazard and may cause injury to the staff. The linkage between the locking device and the cabinet door has poor stability and the connection mechanism is relatively complicated, making maintenance time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where most electrical grounding switch locking devices are linked to electrical cabinet doors. When the door is opened, the locking device is activated. When the door is subjected to external force, the locking device is easily reset, which poses certain safety hazards and may cause injury to workers. Furthermore, the linkage between the locking device and the cabinet door has poor stability and the connection mechanism is cumbersome, making maintenance time-consuming and labor-intensive.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an electrical grounding switch locking device, comprising: a cabinet and a cabinet door, the cabinet and the cabinet door being rotatably connected, a sliding groove being provided at the center of the bottom end of the cabinet, a threaded rod being movably embedded inside the sliding groove, one end of the threaded rod passing through the sliding groove, and further comprising:

[0006] A connecting plate is movably sleeved on the top of the threaded rod, and a rectangular plate is fixedly installed on the top of the connecting plate;

[0007] Two guide plates are fixedly installed on both sides of the top of the rectangular plate, and an L-shaped clamping plate is fixedly installed on one side of the top of each of the two guide plates;

[0008] Both grounding wires are fixedly connected to the outer surface of the conductor plate;

[0009] A limiting hole is provided on the lower side of the cabinet.

[0010] Preferably, a fixing plate is fixedly installed at the bottom of the cabinet body, and a switch body is fixedly installed at the top of the fixing plate.

[0011] The technical effect of adopting the above-mentioned further solution is that the fixing plate facilitates the installation of the switch body and improves the stability of the switch body.

[0012] Preferably, a long strip plate is fixedly installed on the top of the switch body, and two U-shaped contact plates are fixedly installed on the bottom of the long strip plate.

[0013] The technical advantage of adopting the above-mentioned further solution is that the U-shaped contact plate facilitates the embedding of the guide plate inside, so that the switch body can be connected to the locking device.

[0014] Preferably, a mounting plate is fixedly installed at one end of the threaded rod, and a handle is fixedly installed at the upper end of the mounting plate.

[0015] The technical effect of adopting the above-mentioned further solution is that the handle can drive the mounting plate to rotate, thereby driving the threaded rod to rotate.

[0016] Preferably, an insulating sleeve is fixedly installed on the outer surface of the handle.

[0017] The technical effect of adopting the above-mentioned further solution is that the insulating sleeve provides insulation and improves safety when rotating the mounting plate.

[0018] Preferably, a limiting pin is movably embedded at the lower end of the mounting plate, a spring is fixedly connected to the outer surface of the limiting pin, and the other end of the spring is fixedly connected to the outer surface of the mounting plate.

[0019] The technical effect of adopting the above-mentioned further solution is that the spring can drive the limiting pin to embed into the limiting hole, thereby limiting the mounting plate and improving its stability.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the threaded rod is rotated by the mounting plate, and the threaded rod moves through the rectangular plate of the connecting plate. Guide plates are fixedly installed on both sides of the top of the rectangular plate, and an L-shaped clamping plate is fixedly installed on the top of the guide plates. The rectangular plate drives the guide plates to move, so that they are embedded in the interior of the U-shaped contact plate to ground the switch body. The L-shaped clamping plate is fitted on the long strip plate, which can improve the connection between the guide plates and the switch body.

[0022] 2. In this utility model, the limiting pin is embedded in the limiting hole under the elastic force of the spring, which can limit the mounting plate. After the mounting plate is fixed, the threaded rod will not rotate, improving the stability of the connecting plate. This makes it less likely for the grounding locking device to loosen when the inside of the cabinet is inspected, thus improving safety. An insulating sleeve is fixedly installed on the outer surface of the handle, which provides insulation and further improves safety when the mounting plate is rotated. Attached Figure Description

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figure 1-4As shown, this utility model provides an electrical grounding switch locking device, including: a cabinet 1 and a cabinet door 101, which are rotatably connected. A sliding groove 107 is provided at the center of the bottom of the cabinet 1. A threaded rod 108 is movably embedded in the sliding groove 107, and one end of the threaded rod 108 passes through the sliding groove 107. The device also includes: a connecting plate 109, which is movably sleeved on the top of the threaded rod 108. A rectangular plate 118 is fixedly installed on the top of the connecting plate 109; two guide plates 112, which are fixedly installed on both sides of the top of the rectangular plate 118. An L-shaped clamping plate 115 is fixedly installed on one side of the top of each of the two guide plates 112; two grounding wires 114, which are fixedly connected to the outer surface of the guide plates 112; a limiting hole 113, which is opened at the lower end of one side of the cabinet 1; and a fixing plate 110 is fixedly installed at the bottom of the cabinet 1. A switch body 111 is fixedly installed on the top of the fixing plate 110.

[0032] In this embodiment, the threaded rod 108 is rotated by the mounting plate 102, and the threaded rod 108 moves through the rectangular plate 118 of the connecting plate 109. Guide plates 112 are fixedly installed on both sides of the top of the rectangular plate 118, and an L-shaped clamping plate 115 is fixedly installed on the top of the guide plate 112. The rectangular plate 118 drives the guide plate 112 to move, so that it is embedded in the interior of the U-shaped contact plate 117 to ground the switch body 111. The L-shaped clamping plate 115 is fitted on the long strip plate 116, which can improve the connection between the guide plate 112 and the switch body 111.

[0033] Example 2, as Figure 1-4 As shown, a long strip plate 116 is fixedly installed on the top of the switch body 111, and two U-shaped contact plates 117 are fixedly installed on the bottom of the long strip plate 116; a mounting plate 102 is fixedly installed on one end of the threaded rod 108, and a handle 105 is fixedly installed on the upper end of the mounting plate 102; an insulating sleeve 106 is fixedly installed on the outer surface of the handle 105; a limiting pin 103 is movably embedded in the lower end of the mounting plate 102, and a spring 104 is fixedly connected to the outer surface of the limiting pin 103, and the other end of the spring 104 is fixedly connected to the outer surface of the mounting plate 102.

[0034] In this embodiment, the limiting pin 103 is embedded in the limiting hole 113 under the elastic force of the spring 104, which can limit the mounting plate 102. After the mounting plate 102 is fixed, the threaded rod 108 will not rotate, which improves the stability of the connecting plate 109. This makes it less likely for the grounding locking device to loosen when the inside of the cabinet 1 is inspected, thus improving safety. An insulating sleeve 106 is fixedly installed on the outer surface of the handle 105, which has an insulating effect and further improves safety when the mounting plate 102 is rotated.

[0035] Working principle: In use, the mounting plate 102 drives the threaded rod 108 to rotate. The threaded rod 108 moves through the rectangular plate 118 of the connecting plate 109. Guide plates 112 are fixedly installed on both sides of the top of the rectangular plate 118. An L-shaped clamping plate 115 is fixedly installed on the top of the guide plates 112. The rectangular plate 118 drives the guide plates 112 to move, so that they are embedded inside the U-shaped contact plate 117 to ground the switch body 111. The L-shaped clamping plate 115 is fitted onto the long strip plate 116, which can improve the connection between the guide plates 112 and the switch body 111. The connection of the main body 111 is ensured by the limiting pin 103 being embedded in the limiting hole 113 under the elastic force of the spring 104, which can limit the mounting plate 102. After the mounting plate 102 is fixed, the threaded rod 108 will not rotate, thus improving the stability of the connecting plate 109. This makes it less likely for the grounding locking device to loosen when the inside of the cabinet 1 is inspected, improving safety. An insulating sleeve 106 is fixedly installed on the outer surface of the handle 105, which provides insulation and further improves safety when the mounting plate 102 is rotated.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
