[0002] A disconnector is a non-arc-extinguishing switching device mainly used for isolating power supplies, switching operations, and connecting and disconnecting small current circuits. AC high-voltage disconnectors are mainly used in AC high-voltage electrical operations.

[0003] The AC high-voltage disconnect switches with connecting frames currently available on the market have the following problems in actual use:

[0004] 1. In practical use, traditional AC high-voltage disconnect switches with connecting frames have a fixed and short mounting frame. When the switch is installed, the contact area between the switch and the mounting position is small, and there are few mounting points. As a result, the stability of the device is poor after installation.

[0005] 2. Most AC high-voltage disconnect switches with connecting frames have many protruding points and thin parts. When carrying the switch, they may be bumped, which may damage or even deform the parts. Therefore, they are not very protective during use. Utility Model Content

[0006] The purpose of this utility model is to provide an AC high-voltage disconnect switch with a connecting frame to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: An AC high-voltage disconnect switch with a connecting frame includes a mounting frame, a switch body mounted on the top of the mounting frame, a first sliding groove on the side of the mounting frame, a second sliding groove on the other side of the mounting frame, an extension frame sleeved inside the mounting frame, a first external threaded rod welded to the side of the extension frame, the first external threaded rod being located inside the first sliding groove, a nut sleeved on the surface of the first external threaded rod, a limiting rod welded to the other side of the extension frame, the limiting rods being symmetrically distributed, a side plate welded to the other end of the limiting rod, and the surface of the side plate being attached to the surface of the mounting frame.

[0008] Preferably, the mounting bracket has a mounting assembly on its side, the mounting assembly including an internal threaded seat, a second external threaded rod and a retaining ring. The internal threaded seat is welded to the side of the mounting bracket, the second external threaded rod is sleeved inside the internal threaded seat, the retaining ring is welded to the surface of the second external threaded rod, the second external threaded rod passes through the first protective frame, the side of the retaining ring is attached to the side of the first protective frame, the mounting bracket is connected to the second protective frame through the mounting assembly, the first protective frame and the second protective frame are attached to each other, and the switch body is located inside the first protective frame and the second protective frame.

[0009] Preferably, a retaining plate is welded to the side of the first protective frame, and a fixing strip is welded to the side of the second protective frame. The fixing strip is embedded inside the retaining plate, and the retaining plate is connected to the fixing strip by bolts.

[0010] Preferably, a fixing seat is fixedly connected to the top of both the first and second protective frames, and a handle is fixedly connected to the other end of the fixing seat.

[0011] Preferably, a baffle is welded to the other end of the first external threaded rod, and the nut is located between the baffle and the mounting bracket.

[0012] Preferably, a rotating plate is welded to one end of the second external threaded rod, and the second external threaded rod is symmetrically distributed.

[0013] The AC high-voltage disconnect switch with a connecting frame of this utility model has the following advantages:

[0014] 1. An AC high-voltage disconnect switch with a connecting frame is provided by opening a first sliding groove on one side of the mounting frame and a second sliding groove on the other side of the mounting frame. An extension frame is fitted inside the mounting frame, and a first external threaded rod is welded to the side of the extension frame. The first external threaded rod is located inside the first sliding groove, and a nut is fitted onto the surface of the first external threaded rod. A limiting rod is welded to the other side of the extension frame, with the limiting rods symmetrically distributed. A side plate is welded to the other end of the limiting rod, and the surface of the side plate is in contact with the surface of the mounting frame. When installing the switch, the extension frame can be moved through the first and second sliding grooves. The limiting rod provides a limiting effect, preventing the extension frame from rotating. Once the extension frame is moved to the appropriate position, the nut can be rotated to increase the friction between the extension frame and the mounting frame, thus providing a fixing effect. After installation, the extension frame increases the contact area between the switch and the installation position, and the mounting holes on the extension frame increase the number of installation points, further improving the stability of the switch after installation.

[0015] 2. This AC high-voltage disconnect switch with a connecting frame features a mounting assembly on the side of the mounting frame. This mounting assembly includes an internal threaded seat, a second external threaded rod, and a retaining ring. The internal threaded seat is welded to the side of the mounting frame, and the second external threaded rod is fitted inside the internal threaded seat. A retaining ring is welded to the surface of the second external threaded rod, which penetrates through a first protective frame. The retaining ring is flush against the side of the first protective frame. The mounting frame is connected to a second protective frame via the mounting assembly. The first and second protective frames are in close contact, and the switch body is located inside both frames. When carrying the switch, the second external threaded rod can be used to rotate the first and second protective frames, allowing them to conceal the switch body. This provides strong protection during use, as the first and second protective frames protect the switch body from impacts. Attached Figure Description

[0029] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an AC high-voltage disconnecting switch with a connecting frame.

[0030] like Figure 1-6 As shown, this utility model discloses an AC high-voltage disconnecting switch with a connecting frame, including a mounting frame 1. A switch body 2 is mounted on the top of the mounting frame 1. A first sliding groove 4 is formed on one side of the mounting frame 1, and a second sliding groove 8 is formed on the other side. An extension frame 3 is sleeved inside the mounting frame 1. A first external threaded rod 5 is welded to the side of the extension frame 3. By installing the extension frame 3, the contact area between the switch and the mounting position can be increased during installation. Furthermore, the mounting holes on the extension frame 3 can increase the number of mounting points, thereby further improving the safety of the switch. For post-installation stability, the first external threaded rod 5 is located inside the first slide groove 4, and a nut 6 is sleeved on the surface of the first external threaded rod 5. A limiting rod 10 is welded to the other side of the extension frame 3. The limiting rods 10 are symmetrically distributed, and a side plate 9 is welded to the other end of the limiting rod 10. The surface of the side plate 9 is attached to the surface of the mounting frame 1. By installing the limiting rod 10, when the extension frame 3 moves through the first slide groove 4 and the second slide groove 8, the limiting rod 10 can provide a limiting effect for the extension frame 3, so that the extension frame 3 will not rotate, ensuring the stability of the extension frame 3 when it moves during use.

[0031] The mounting bracket 1 has a mounting assembly on its side, which includes an internal thread seat 13, a second external thread rod 14, and a retaining ring 15. The internal thread seat 13 is welded to the side of the mounting bracket 1, and the second external thread rod 14 is sleeved inside the internal thread seat 13. The retaining ring 15 is welded to the surface of the second external thread rod 14, and the second external thread rod 14 passes through the first protective frame 11. The side of the retaining ring 15 is attached to the side of the first protective frame 11. The mounting bracket 1 is connected to the second protective frame 12 through the mounting assembly. The first protective frame 11 and the second protective frame 12 are attached to each other. The switch body 2 is located inside the first protective frame 11 and the second protective frame 12. By installing the first protective frame 11 and the second protective frame 12, the switch body 2 can be protected by the first protective frame 11 and the second protective frame 12 when carrying the switch, so that the switch body 2 will not be hit, and the protection is strong when in use.

[0032] The first protective frame 11 has a plate 20 welded to its side, and the second protective frame 12 has a fixing strip 19 welded to its side. The fixing strip 19 is embedded inside the plate 20, and the plate 20 is connected to the fixing strip 19 by bolts. By connecting the fixing strip 19 and the plate 20 by the mounting bolts, a fixing effect can be provided between the first protective frame 11 and the second protective frame 12, so that the first protective frame 11 and the second protective frame 12 will not easily expose the switch body 2, and the fixing effect between the first protective frame 11 and the second protective frame 12 can be guaranteed during use.

[0033] The top of the first protective frame 11 and the second protective frame 12 are both fixedly connected to the fixing base 17, and the other end of the fixing base 17 is fixedly connected to the handle 18. By installing the handle 18, when carrying the switch, the handle 18 can be used as the force point, and the switch can be carried directly through the handle 18, which is very convenient when using it.

[0034] A baffle 7 is welded to the other end of the first external thread rod 5. The nut 6 is located between the baffle 7 and the mounting bracket 1. By installing the baffle 7, the nut 6 can be limited so that it will not come off the first external thread rod 5, which is very convenient to use.

[0035] The second external threaded rod 14 has a rotating plate 16 welded to one end. The second external threaded rod 14 is symmetrically distributed. The distribution of the second external threaded rod 14 can further improve the stability of the first protective frame 11 and the second protective frame 12 after installation, resulting in strong stability during use.

[0036] The working principle of this AC high-voltage disconnect switch with a connecting frame is as follows: When using this switch, it should first be carried to the installation position. At this point, a mounting assembly is provided on the side of the mounting frame 1. This mounting assembly includes an internal threaded seat 13, a second external threaded rod 14, and a retaining ring 15. The internal threaded seat 13 is welded to the side of the mounting frame 1, and the second external threaded rod 14 is sleeved inside the internal threaded seat 13. The retaining ring 15 is welded to the surface of the second external threaded rod 14. The second external threaded rod 14 passes through the first protective frame 11, and the side of the retaining ring 15 fits against the side of the first protective frame 11. The mounting frame 1 is connected to the second protective frame 12 through the mounting assembly. At this point, the first protective frame 11 and the second protective frame 12 are fitted together, and the switch body 2 is located inside the first protective frame 11 and the second protective frame 12. When carrying the switch, the first protective frame 11 and the second protective frame 12 can be rotated using the second external threaded rod 14, thereby allowing the first protective frame 11 and the second protective frame 12 to conceal the switch body 2. When carrying the switch, the first protective frame 11 and the second protective frame 12 can protect the switch body 2 from impacts, providing strong protection during use. Once the switch is in a suitable position, the second external threaded rod 14 can be removed. Afterwards, the first protective frame 11 and the second protective frame 12 are removed, and then the switch is installed. During installation, a first groove 4 is opened on one side of the mounting bracket 1, and a second groove 8 is opened on the other side. Simultaneously, an extension bracket 3 is fitted inside the mounting bracket 1, and a first external threaded rod 5 is welded to the side of the extension bracket 3. At this time, the first external threaded rod 5 is located inside the first groove 4. A nut 6 is fitted onto the surface of the first external threaded rod 5. A limiting rod 10 is welded to the other side of the extension bracket 3. The limiting rods 10 are symmetrically distributed, and a side plate 9 is welded to the other end of the limiting rod 10. The surface of the side plate 9 is then attached to the surface of the mounting bracket 1. During switch installation, the extension bracket 3 can be moved via the first slide rail 4 and the second slide rail 8. At this time, the limiting rod 10 can provide a limiting effect for the extension bracket 3, preventing it from rotating. After the extension bracket 3 is moved to the appropriate position, the nut 6 can be rotated to increase the friction between the extension bracket 3 and the mounting bracket 1, thereby providing a fixing effect for the extension bracket 3. When installing the switch, the contact area between the switch and the installation position can be increased by using the extension bracket 3, and the mounting holes on the extension bracket 3 can increase the number of installation points, thereby further improving the stability of the switch after installation. After that, it can be directly installed and used.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
