Description

Technical Field

[0001] This utility model relates to the field of rotary switch technology, specifically to a side-operated structure for an isolating switch. Background Technology

[0002] In low-voltage power distribution systems, disconnecting switches are commonly used to connect and disconnect circuits. The operating mechanism is an important component of the disconnecting switch. The operator drives the operating mechanism manually or electrically to move the moving contact mechanism of the contact system to connect or disconnect the circuit.

[0003] Traditional disconnect switches typically use gears to achieve their function. Due to the multi-stage meshing of gears, there is sliding friction and rolling friction, which reduces energy transfer efficiency and causes significant energy loss during energy storage. At the same time, the transmission system composed of multiple components such as gears, shafts, and bearings has a complex structure and requires high installation precision. Improper assembly can easily lead to vibration or noise. Utility Model Content

[0004] The purpose of this invention is to provide a side-operated structure for a disconnecting switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a side-operated structure for a disconnecting switch, comprising a face cover, a top cover, and a bottom box with mutually mating assembly structures. An operating mechanism is provided inside the bottom box, comprising an operating shaft, a cam, a connecting shaft, a pull plate, an energy storage spring, and a vertical plate. The vertical plate is fixed to the bottom box, and an energy storage spring is provided on the outside of the pull plate, with one end of the pull plate fixed to the vertical plate. The cams are symmetrically arranged, and a connecting shaft is inserted between them. The other end of the pull plate is sleeved on the connecting shaft. An operating shaft is provided at the upper end of the cam, and the operating shaft rotates coaxially with the cam to drive the energy storage spring to store or release energy.

[0006] Furthermore, the bottom box is divided into multiple chambers, one of which has an integrally formed mounting column with a groove for inserting a mounting plate to form a snap-fit ​​fixation.

[0007] Furthermore, the face cover is fixed to the upper cover by bolts, wherein the face cover has a cavity formed on the side facing the upper cover, the cavity covers the outside of the operating shaft, and the inner wall of the cavity is symmetrically provided with limiting parts.

[0008] Furthermore, a protruding abutment bar is provided on the operating shaft. The abutment bar is movably disposed between symmetrical limiting parts, and when it abuts against different limiting parts, it corresponds to the energy storage or energy release state respectively.

[0009] Furthermore, a groove is formed in the middle of the upright plate, and a pin is provided in the groove and passes through the pull plate. The pin is fixed to the mounting column through the upright plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by adopting a direct linkage structure of cam, pull plate and energy storage spring, multi-stage gear meshing is eliminated, sliding friction and rolling friction are reduced, energy transfer efficiency is improved, and mechanical losses in the energy storage process are significantly reduced.

[0011] The energy storage spring achieves linear compression through the coaxial linkage between the pull plate and the cam, avoiding energy dispersion in gear transmission and ensuring a fast and precise energy storage and release process. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5A side-operated structure for a disconnector switch includes a face cover 40, an upper cover 10, and a base box 20 with interlocking assembly structures. An operating mechanism 30 is disposed within the base box 20. The operating mechanism 30 includes an operating shaft 301, a cam 302, a connecting shaft 303, a pull plate 304, an energy storage spring 305, and a vertical plate 306. The vertical plate 306 is fixed to the base box 20. An energy storage spring 305 is disposed on the outer side of the pull plate 304, and one end of the pull plate 304 is fixed to the vertical plate 306. The cams 302 are symmetrically arranged, with the connecting shaft 303 inserted between them. The other end of the pull plate 304 is sleeved on the connecting shaft 303. An operating shaft 301 is disposed on the upper end of the cam 302. The coaxial rotation of the cam 302 drives the energy storage spring 305 to store or release energy. The core of the drive consists of the coaxially nested operating shaft 301 and the double cam 302. The cam 302 achieves synchronous deflection, and the profile of the cam 302 ensures the non-linear characteristics of the torque output. The double-end preloaded energy storage spring 305 is adopted, and a guide plate 304 is set on its outer side. The front end of the guide plate 304 forms a rigid constraint with the vertical plate 306 through the positioning pin 307, forming an efficient energy storage-release conversion mechanism. The direct linkage structure of the cam 302, the guide plate 304, and the energy storage spring 305 is adopted, eliminating multi-stage gear meshing, reducing sliding friction and rolling friction, improving energy transfer efficiency, and significantly reducing mechanical losses in the energy storage process.

[0024] In this embodiment, the base box 20 is divided into multiple chambers, one of which has an integrally formed mounting column 201. The mounting column 201 has a groove for inserting a vertical plate 306 to form a snap-fit ​​fixation. The base box 20 is thus divided into multiple independent chambers. This division helps improve the utilization rate of the internal space of the base box 20, making the overall structure of the device more compact and rational. Specifically, the mounting column 201 in the middle chamber of the base box 20 is manufactured using an integral molding process. This integral molding process ensures extremely high connection strength and stability between the mounting column 201 and the chamber of the base box 20, avoiding loosening or displacement problems that may occur during later assembly, thereby greatly improving the structural reliability and service life of the entire device. The mounting column 201 has a specially designed groove for inserting the vertical plate 306 to form a snap-fit ​​fixation. When the upright plate 306 is accurately inserted into the groove, the tight fit between the groove and the upright plate 306 generates sufficient friction and mechanical interlocking force, which firmly fixes the upright plate 306 to the mounting column 201, ensuring the stability and reliability of the upright plate 306 during the operation of the device and providing a solid guarantee for the normal operation of the entire device.

[0025] In this embodiment, the face cover 40 is fixed to the upper cover 10 by bolts. A cavity 401 is formed on the side of the face cover 40 facing the upper cover 10. The cavity 401 covers the outside of the operating shaft 301. Limiting parts 4011 are symmetrically provided on the inner wall of the cavity 401. The face cover 40 is fixed to the upper cover 10 by bolts. The bolt connection can provide sufficient strength and stability to ensure that the face cover 40 and the upper cover 10 maintain a relatively fixed position during equipment operation. The cavity 401 formed on the side of the face cover 40 facing the upper cover 10 covers the outside of the operating shaft 301, providing a relatively independent space for the operating shaft 301. This can protect the operating shaft 301 from interference from the external environment, and also play a certain role in restricting and guiding the movement of the operating shaft 301.

[0026] In this embodiment, a protruding abutment strip 3011 is provided on the operating shaft 301. This abutment strip 3011 is movably disposed between symmetrical limiting portions 4011, and its contact with different limiting portions 4011 corresponds to energy storage or energy release states, respectively. The protruding abutment strip 3011 is movable and can move between the symmetrically distributed limiting portions 4011. When the abutment strip 3011 contacts a specific position within the limiting portions 4011, it corresponds to a specific state—energy storage; and when the abutment strip 3011 moves to and contacts another limiting portion 4011, it switches to another state—energy release. This design not only achieves stable switching of the operating shaft 301 between different states but also ensures the reliability and accuracy of the entire mechanical system. By adjusting the position of the abutment strip 3011 between the limiting portions 4011, the energy storage and release of the mechanical system can be easily controlled.

[0027] In this embodiment, a groove 3061 is formed in the middle of the upright plate 306. A pin 307 is disposed in the groove 3061 and passes through the pull plate 304. The pin 307 is fixed to the mounting column 201 via the upright plate 306. The groove 3061 in the middle of the upright plate 306 facilitates the installation and fixation of subsequent components. The pin 307 is securely placed in the groove 3061, ensuring its positional accuracy and enhancing the stability of the entire structure. One end of the pin 307 passes through the pull plate 304. Simultaneously, the pin 307 is connected to the mounting column 201 via the upright plate 306, forming a firm fixation and ensuring the reliability and safety of the entire device during long-term use.
