[0001] This utility model relates to the field of switch handle technology, and in particular to a power distribution switch handle that is easy to operate. Background Technology

[0002] The switch handle is an indispensable and important component of the power distribution system, undertaking multiple functions such as controlling the switch, controlling the power supply, and protecting the equipment. By operating the handle, the circuit can be connected, disconnected, and switched. Currently, when replacing the switch handle, disassembly is cumbersome and installation is inconvenient, which is not conducive to improving the maintenance efficiency of the staff.

[0003] To address the aforementioned problems, this utility model document proposes an easy-to-operate power distribution switch handle. Utility Model Content

[0004] This utility model provides an easy-to-operate power distribution switch handle, which solves the shortcomings of the prior art where the power distribution switch handle is cumbersome to disassemble and inconvenient to install when replacing, which is not conducive to improving the maintenance efficiency of the staff.

[0005] This utility model provides the following technical solution:

[0006] Easy-to-operate power distribution switch handles, including:

[0007] A U-shaped fixing frame is provided with a matching docking shaft rotatably mounted on the U-shaped fixing frame. A rectangular connecting rod is engaged in a first groove on one side of the docking shaft. A screwing block is provided at the other end of the rectangular connecting rod. A second groove for engaging the other end of the rectangular connecting rod is provided in the center of one side of the screwing block. An anti-slip handle is fixedly mounted on the other side of the screwing block.

[0008] The first limiting structure is located on the mating shaft and the rectangular connecting rod to facilitate the fixing and disassembly of both.

[0009] The second limiting structure is located on the screw block and the rectangular connecting rod to facilitate the fixing and disassembly of both.

[0010] In one possible design, the first limiting structure includes a first bolt disposed on a mating shaft, the mating shaft having a threaded hole for threaded connection of the first bolt, and the rectangular connecting rod having a first through hole for mating the end of the first bolt.

[0011] In one possible design, the second limiting structure includes a round-headed abutment that is slidably installed in the cavity of a rectangular connecting rod. The cavity of the rectangular connecting rod is connected to the side wall of the first through hole. The other end of the cavity of the rectangular connecting rod is connected to an installation groove. Two second through holes are symmetrically arranged on the inner wall of the installation groove. A corresponding round-headed locking block is slidably installed in the second through hole. A locking groove for locking the protruding end of the corresponding round-headed locking block is provided on the inner wall of the second groove.

[0012] In one possible design, a mounting plate is fixedly provided at the round end of the round head block, and a first tension spring for resetting the round head block is fixedly provided between the inner side of the mounting plate and the inner wall of the mounting groove.

[0013] In one possible design, both of the round-headed blocks are perpendicular to each other with the round-headed abutment.

[0014] In one possible design, each of the four corners of the U-shaped fixing bracket is provided with a strip-shaped hole, and a corresponding second bolt is provided in the strip-shaped hole. The ends of the first bolt and the second bolt are both provided with internal hexagonal grooves.

[0015] In one possible design, a dustproof sheet is slidably disposed within the internal hexagonal recess to prevent dust accumulation on the inner wall, and a second tension spring for resetting the dustproof sheet is fixedly disposed between the bottom of the dustproof sheet and the bottom of the inner wall of the internal hexagonal recess.

[0016] In one possible design, two limiting plates are symmetrically arranged on the dustproof sheet, and the inner wall of the hexagonal groove is provided with a limiting groove that slides to connect the corresponding limiting plates.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0018] The working principle and usage process of this technical solution are as follows:

[0019] During installation, use the strip hole and the second bolt to fix the U-shaped bracket to the appropriate position of the power distribution switch. When no tools are used, the dustproof plate inside the bolt will automatically reset under the action of the second tension spring, covering the opening of the hexagonal groove. Insert the first end of the rectangular connecting rod into the first groove of the mating shaft, and insert the other end of the rectangular connecting rod into the second groove of the screwing block.

[0020] Then, the first bolt is screwed into the threaded hole, and its end passes through the first through hole, thus forming a firm connection. As the first bolt is screwed into the first through hole, the bottom end of the first bolt pushes the round head abutment rod to move, thereby causing the round head locking block to be pushed into the second through hole, so that its protruding end is locked into the slot, thus forming a firm connection. When disassembling and separating the rectangular connecting rod from the mating shaft, after the first bolt is screwed out of the first through hole, the compressed first tension spring resets and drives the corresponding round head locking block to retract into the second through hole, so that the round head locking block is disengaged from the slot, thus simultaneously realizing the separation of the rectangular connecting rod and the screwing block.

[0021] This utility model has the following beneficial effects:

[0022] This utility model uses a combination of a first limiting structure and a second limiting structure to achieve the synchronous separation and installation of the rectangular connecting rod and the docking shaft, as well as the rectangular connecting rod and the tightening block, by simply tightening a single first bolt. It is convenient to use and helps improve the maintenance efficiency of workers.

[0023] The dustproof plate in this invention effectively prevents dust from accumulating on the inner wall of the hexagonal groove, extends the service life of the bolt, and ensures the smooth installation and disassembly of the tool. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] Example 1

[0034] Please refer to Figure 1-5 The handle includes:

[0035] A U-shaped fixing bracket 1 is designed in shape and size to be securely installed in the appropriate position of the power distribution switch. A docking shaft 2 is rotatably mounted on the U-shaped fixing bracket 1. The docking shaft 2 is designed to rotate relative to the U-shaped fixing bracket 1. A first groove 3 is formed on one side of the docking shaft 2. The shape and size of the groove are designed to engage a rectangular connecting rod 4. The rectangular connecting rod 4 is designed to be securely inserted and fixed in the first groove 3, thereby forming a stable connection. At the other end of the rectangular connecting rod 4, a screw block 5 is provided. A second groove 6 is formed in the center of one side of the screw block 5. The shape and size of the groove match the other end of the rectangular connecting rod 4, so that the rectangular connecting rod 4 can be securely engaged in the second groove 6.

[0036] On the other side of the screw block 5, a non-slip handle 7 is fixedly installed. The design of the non-slip handle 7 takes into account ergonomics and anti-slip performance, so that the operator can feel comfortable and not easily slip when operating the handle.

[0037] To enable the fixing and disassembly of the docking shaft 2 and the rectangular connecting rod 4, a first limiting structure is provided. Specifically, a first bolt 9 is provided on the docking shaft 2, and a threaded hole 8 for threaded connection of the first bolt 9 is opened on the docking shaft 2. At the same time, a first through hole 10 for docking the end of the first bolt 9 is opened on the rectangular connecting rod 4. When it is necessary to fix the docking shaft 2 and the rectangular connecting rod 4, simply screw the first bolt 9 into the threaded hole 8 and let its end pass through the first through hole 10, thereby forming a firm connection.

[0038] To achieve the fixing and disassembly of the screwing block 5 and the rectangular connecting rod 4, a second limiting structure is provided. Specifically, a round-headed abutment 11 is slidably installed inside the cavity of the rectangular connecting rod 4. The design of this abutment allows it to slide freely within the cavity. Simultaneously, a mounting groove 12 is opened at the other end of the cavity of the rectangular connecting rod 4, and two second through holes 14 are symmetrically arranged on the inner wall of the mounting groove 12. A corresponding round-headed locking block 13 is slidably installed in each second through hole 14. On the inner wall of the second groove 6, a slot 15 is provided for engaging the protruding end of the corresponding round head block 13. When the first bolt 9 is screwed into the first through hole 10, the bottom end of the first bolt 9 pushes the round head abutment 11 to move, thereby causing the round head block 13 to be pushed into the second through hole 14, so that its protruding end is engaged in the slot 15, thus forming a firm connection. In addition, both round head blocks 13 are perpendicular to the round head abutment 11 to ensure that the round head blocks 13 can be stably engaged in the slot 15 and are not easy to fall off.

[0039] To facilitate the reset of the round-headed locking block 13, a mounting plate 16 is fixedly provided at the round end of each round-headed locking block 13, and a first tension spring 17 for resetting the round-headed locking block 13 is fixedly provided between the inner side of the mounting plate 16 and the inner wall of the mounting groove 12. In this way, when the first bolt 9 is unscrewed out of the first through hole 10, the compressed first tension spring 17 resets and drives the corresponding round-headed locking block 13 to retract into the second through hole 14, so that the round-headed locking block 13 is disengaged from the locking groove 15, thereby realizing the separation of the two.

[0040] At the four corners of the U-shaped fixing bracket 1, there are strip holes 18, and corresponding second bolts 19 are installed in the strip holes 18. The design of these second bolts 19 allows the U-shaped fixing bracket 1 to be firmly installed in the appropriate position of the power distribution switch. At the same time, the ends of the first bolt 9 and the second bolt 19 are provided with internal hexagonal grooves 21 to facilitate tightening and disassembly using tools such as internal hexagonal wrenches.

[0041] Example 2

[0042] An improvement based on Embodiment 1: an easy-to-operate power distribution switch handle, which is used in the field of switch handles.

[0043] Please refer to Figure 5 To prevent dust from accumulating on the inner wall of the hexagonal recess 21, a dustproof sheet 20 is slidably installed in each hexagonal recess 21. A second tension spring 22 for resetting the dustproof sheet 20 is fixed between the bottom of the dustproof sheet 20 and the bottom of the inner wall of the hexagonal recess 21. In this way, when tools such as hexagonal wrenches are not used, the dustproof sheet 20 can automatically cover the opening of the hexagonal recess 21 to prevent dust from entering.

[0044] To facilitate the sliding and resetting of the dustproof sheet 20, two limiting pieces 23 are symmetrically arranged on the dustproof sheet 20, and a limiting groove 24 corresponding to the limiting piece 23 is provided on the inner wall of the internal hexagonal groove 21. In this way, the dustproof sheet 20 can remain stable when sliding and is not easy to fall off.

[0045] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.
