Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-5 As shown, a disconnecting switch with a protective cover includes a disconnecting switch body 1. A protective auxiliary mechanism 5 is provided on the outside of the disconnecting switch body 1. The protective auxiliary mechanism 5 includes a protective cover body 51 that is sleeved on the outside of the disconnecting switch body 1. A guide frame 52 is fixedly connected to one end of the protective cover body 51. A support seat 53 is movably connected to the inside of the guide frame 52. A rotating shaft 54 ​​is fixedly connected inside the support seat 53. A guide groove 55 is opened at the front end of the protective cover body 51. A threaded rod 56 is slidably connected to the inside of the guide groove 55. A limit ring 57 is fixedly connected to the outside of the threaded rod 56 near the guide groove 55. A contact pad 58 is slidably connected to the outside of the threaded rod 56 near the guide groove 55. A fastening nut 59 is threadedly connected to the outside of the threaded rod 56 near the contact pad 58.

[0022] In this embodiment, a transparent plate 510 is embedded inside the protective cover body 51, and a contact sleeve 511 is fixedly connected to the inner wall of the protective cover body 51. The guide frame 52 is L-shaped, the lower end of the support base 53 is fixedly connected to the upper end of the disconnect switch body 1, the rotating shaft 54 ​​extends into the interior of the guide frame 52, and the rotating shaft 54 ​​is movably connected to the guide frame 52. The guide groove 55 is arc-shaped, and the axis of the guide groove 55 and the rotating shaft 54 ​​are on the same straight line. One end of the threaded rod 56 is fixedly connected to one end of the disconnect switch body 1. The limiting ring 57 is in contact with the protective cover body 51, and the contact pad 58 is in contact with the protective cover body 51. The main material of the contact pad 58 is rubber, and one end of the contact pad 58 is in contact with one end of the fastening nut 59. The main material of the transparent plate 510 is acrylic plate, and the rear end of the contact sleeve 511 is in contact with the front end of the disconnect switch body 1. The main material of the contact sleeve 511 is rubber.

[0023] Specifically, pushing the protective cover body 51 causes the controller 2 to rotate around the support base 53 via the rotating shaft 54. This causes the rotating shaft 54 ​​to slide along the guide groove 55, covering the protective cover body 51 on the outside of the disconnector switch body 1. Then, tightening the fastening nut 59 causes it to press against the contact pad 58, deforming the contact pad 58. This allows the fastening nut 59 to restrict the movement of the protective cover body 51 via the contact pad 58, thus confining the protective cover body 51 to the outside of the disconnector switch body 1. This ensures that the protective cover body 51 is positioned relative to the disconnector switch body 1. To provide protection, pressing the protective cover body 51 causes the guide frame 52 to rotate around the support base 53 with the rotation axis 54 as the axis. This allows the protective cover body 51 to rotate along the threaded rod 56 through the guide groove 55, so that the protective cover body 51 can be smoothly rotated to the outside of the disconnect switch body 1. Tightening the fastening nut 59 then limits the position of the protective cover body 51, making it easy to secure the protective cover body 51 to the outside of the disconnect switch body 1. This allows the protective cover body 51 to protect the disconnect switch body 1 and prevent accidental contact with the disconnect switch body 1.

[0024] In this embodiment, a controller 2 is installed on the upper side of the front end of the disconnect switch body 1 near the contact sleeve 511, a connection hole 3 is opened at the lower end of the disconnect switch body 1, and a threaded head 4 is installed inside the disconnect switch body 1. There are multiple sets of both the connection hole 3 and the threaded head 4.

[0025] Specifically, first, the disconnect switch body 1 is installed in the distribution box, and the external cable is installed in the disconnect switch body 1. Then, the cable is inserted into the connection hole 3 and installed in the connection hole 3. Then, the controller 2 is pushed so that the disconnect switch body 1 connects the external cable to the cable.

[0026] Working principle:

[0027] In use, first install the disconnect switch body 1 inside the distribution box, and then install the external cable inside the disconnect switch body 1. Next, insert the cable into the connection hole 3 and install the cable inside the connection hole 3. Then push the controller 2 to connect the disconnect switch body 1 to the external cable. Then push the protective cover body 51 to make the protective cover body 51 drive the controller 2 to rotate around the support base 53 on the rotating shaft 54. The rotating shaft 54 ​​slides along the guide groove 55 and covers the outside of the disconnect switch body 1. Then tighten the fastening nut 59 to compress the contact pad 58, causing the contact pad 58 to deform. This allows the fastening nut 59 to limit the protective cover body 58 through the contact pad 58. The movement of 1 can confine the protective cover body 51 to the outside of the disconnect switch body 1, thereby enabling the protective cover body 51 to protect the disconnect switch body 1. By pressing the protective cover body 51, the guide frame 52 rotates around the support base 53 with the rotating shaft 54 ​​as the axis, and then the protective cover body 51 rotates along the threaded rod 56 through the guide groove 55, so that the protective cover body 51 is smoothly rotated to the outside of the disconnect switch body 1. Then, tightening the fastening nut 59 will limit the position of the protective cover body 51, so as to make it easy to smoothly lock the protective cover body 51 to the outside of the disconnect switch body 1, thereby enabling the protective cover body 51 to protect the disconnect switch body 1 and prevent accidental contact with the disconnect switch body 1.
