[0001] The utility model belongs to a switch operating mechanism of a flameproof control cabinet, in particular to a switch operating mechanism of a flameproof control cabinet. Background Art

[0002] An explosion-proof control cabinet is an electrical control device used in hazardous environments. It is mainly used in places where flammable and explosive gases, dust, etc. may cause explosions, such as petrochemical, underground coal mines, natural gas extraction and other industrial environments. Structurally, the shell of the explosion-proof control cabinet has a special explosion-proof design that can withstand the pressure generated by internal explosions without damage, and can prevent the explosion flame and high-temperature gas from spreading to the external environment, thereby avoiding causing explosions in the surrounding environment. Various electrical control components such as circuit breakers, contactors, and relays are installed inside to control the operation of equipment such as motors, lamps, and sensors. Through reasonable wiring and connection, precise control and protection of equipment in industrial processes can be achieved. In terms of function, it can not only ensure the safe and stable operation of equipment in hazardous environments, but also provide multiple protection functions such as overload, short circuit, and leakage, effectively preventing explosion accidents caused by electrical faults. It is one of the key equipment to ensure safe production in hazardous areas.

[0003] The flameproof control cabinet switch is a key component of the flameproof control cabinet. It is installed in the flameproof control cabinet and is mainly used to control the on and off of the circuit. This switch has flameproof performance, and its shell can effectively prevent the electric sparks and arcs generated inside from being released into the surrounding flammable and explosive environment. In terms of design, it adopts a special sealing structure and high-strength shell material to withstand the impact pressure of explosion. It can accurately open or close electrical equipment, such as motors and lighting systems, to ensure the safe and stable operation of equipment in areas with explosion hazards, such as petrochemicals, coal mines, etc., and is an important guarantee for the realization of safe control circuits.

[0004] The Chinese patent with the announcement number "CN215644161U" discloses a flameproof control cabinet switch operating mechanism, which includes a rotary handle, a rotary switch shaft arranged laterally arranged internally on the right side of the rotary handle, a fixed bracket connected to the right side of the fixed bracket, a sealing strip connected to the right side of the sealing strip, a connecting bracket connected to the right side of the fixed bracket, a connecting bolt arranged laterally arranged at the connection between the fixed bracket and the connecting bracket, the connecting bolt connects the fixed bracket, the sealing strip and the connecting bracket, the right side of the connecting bracket is connected to the control cabinet door, a rotary switch shaft sleeve is provided on the right side of the control cabinet door, a fastening kit is provided on the inner side of the rotary switch shaft sleeve, the rotary switch shaft laterally passes through the fixed bracket, the connecting bracket and the control cabinet door, a second retaining spring is provided at the relative position on the left side of the rotary switch shaft end, and the second retaining spring is placed in the relative position inside the connecting bracket. The beneficial effects of the utility model are: it can be flexibly rotated, the assembly accuracy and assembly efficiency are improved, and it is easy to maintain;

[0005] In the actual use of the above-mentioned operating mechanism, although it has the characteristic of flexible rotation, which significantly improves the assembly accuracy and assembly efficiency and also brings convenience to subsequent maintenance work, the operating mechanism mainly relies on screws or other threaded connections to achieve fixed installation with the cabinet door. During the specific disassembly and assembly process, some obvious problems are exposed. First, it is necessary to use special tools such as screwdrivers to remove the bolts before the operating mechanism can be removed from the cabinet door. This method is often cumbersome and consumes a lot of time and energy. Second, during the multiple disassembly and assembly process, it is inevitable that the screws will cause a certain degree of damage, such as wear of the screw threads. Moreover, in a long-term use environment, the screws are easily affected by external factors such as rust and dust. When the screws are rusted or covered with a large amount of dust, they are very likely to slip when the disassembly operation is carried out again, which further increases the difficulty of disassembly and may even make it impossible to disassemble smoothly, seriously affecting the convenience of use and maintenance efficiency of the operating mechanism. It can be seen that the operating mechanism has certain defects in the current application process and urgently needs to be improved and optimized accordingly to enhance its overall performance and practicality.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A switch operating mechanism for an explosion-proof control cabinet comprises a cabinet door, a mounting groove being formed on one side of the cabinet door, a limiting mechanism being fixedly connected in a ring-shaped manner along the edge of the mounting groove at equal intervals on the side of the cabinet door close to the mounting groove, the limiting mechanisms being provided in three groups, the three limiting mechanisms being arranged in an isosceles triangle and arranged on the outside of the mounting groove, a switch sleeve being inserted into the inside of the mounting groove through the limiting mechanism, a connecting rod being installed on the rear side of the switch sleeve, an isolating switch being installed on the rear side of the connecting rod, a front end of the switch sleeve passing through the mounting groove and being rotatably connected to a rotating handle, a linkage mechanism being movably installed on the side of the cabinet door close to the mounting groove, the linkage mechanism and the three limiting mechanisms being linked to each other;

[0009] The limiting mechanism includes a limiting groove and a guide rail. The limiting groove is opened at the top, bottom and one side of the switch sleeve. The guide rail is fixedly installed in the middle of one side of the cabinet door close to the installation groove. The guide rails are provided in three and are arranged in a ring shape on the outside of the installation groove. The interior of the guide rail is fixedly connected to the limiting component, and the end of the limiting component passes through the guide rail and is inserted into the interior of the limiting groove.

[0010] As an optimal technical solution, the limit assembly includes a telescopic spring, which is fixedly installed inside the guide rail. The end of the telescopic spring is fixedly connected to a sliding rod, which is slidably connected to the inside of the guide rail. The end of the sliding rod passes through the guide rail and is fixedly installed with a limit block. The end of the limit block is inserted into the inner side of the limit groove.

[0011] As an optimal technical solution, the linkage mechanism includes a mounting part and a first articulated wheel. The mounting parts are arranged in a ring shape at equal intervals and fixedly installed on the side of the cabinet door close to the mounting groove. The cabinet door is installed with a slip ring through the mounting part. The slip ring is arranged in a ring shape on the side close to the cabinet door and is rotatably connected to the second articulated wheel. The second articulated wheel and the guide rail are arranged correspondingly. The first articulated wheel is rotatably connected to the outer side of the sliding rod close to one end of the mounting groove. A push rod is fixedly connected between the first articulated wheel and the second articulated wheel.

[0012] As an optimal technical solution, the mounting part includes a mounting plate, which is arranged in a ring shape with equal intervals and is arranged on the side of the cabinet door close to the mounting groove. The mounting plate is arranged on the outside of the mounting groove on the cabinet door. A support rod is fixedly installed on the side of the mounting plate away from the cabinet door, and an arc-shaped sliding frame is fixedly installed on the end of the support rod. The slip ring is slidably connected to the inner side of the arc-shaped sliding frame.

[0013] As a preferred technical solution, a handle is rotatably connected to the middle of one side of the sliding ring away from the cabinet door, and an anti-slip armrest cover is fixedly connected to the outer surface of the handle.

[0014] As an optimal technical solution, the mounting plate is provided with mounting holes at equal intervals on a side away from the cabinet door.

[0016] In summary, the present invention has the following beneficial effects:

[0017] First, the limit mechanism brings great convenience to the installation and disassembly of the device. During installation, adjust the slide bar to slide toward the inside of the guide rail, the slide bar squeezes the telescopic spring to shrink it, and the limit block is then retracted into the inside of the guide rail. Then, fill the switch sleeve into the installation slot, and the telescopic spring resets to drive the slide bar to move outward, so that the limit block is inserted into the limit slot, completing the stable installation of the switch sleeve in the installation slot. During disassembly, adjust the slide bar to squeeze the spring again to disengage the limit block from the limit slot, and then the switch sleeve can be easily removed from the installation slot. In terms of disassembly, assembly and maintenance of the switch sleeve and disconnector, this limit mechanism shows superb convenience, which significantly improves the efficiency of maintenance work.

[0018] Second, when the switch sleeve in the installation groove needs to be disassembled, the operator holds the handle and pushes the slip ring to rotate in the arc-shaped slide frame, which in turn drives the second articulated wheel, the push rod, and the first articulated wheel to rotate, so that the slide rod slides toward the inside of the guide rail. The sliding of the slide rod not only squeezes the telescopic spring to contract, but also allows the limit block to be withdrawn from the limit groove, so that the switch sleeve can be smoothly removed or installed. Only pulling the handle can link the three limit mechanisms, which not only quickly disassembles and maintains, but also avoids the disadvantages of dust clogging, rust and thread slippage in the threaded connection, thereby improving the convenience, practicality and reliability of the device and giving users a better experience.

[0024] Example

[0025] refer to Figures 1 to 4, a flameproof control cabinet switch operating mechanism of this embodiment includes a cabinet door 1, a mounting groove 2 is opened on one side of the cabinet door 1, and a limiting mechanism 3 is fixedly connected in a ring shape along the edge of the mounting groove 2 at equal intervals on one side of the cabinet door 1 close to the mounting groove 2. The limiting mechanism 3 is provided in three groups, and the three limiting mechanisms 3 are arranged in an isosceles triangle on the outside of the mounting groove 2. A switch sleeve 4 is inserted into the inner side of the mounting groove 2, and the switch sleeve 4 is installed in the inside of the mounting groove 2 through the limiting mechanism 3. A connecting rod 5 is installed on the rear side of the switch sleeve 4, and an isolating switch 6 is installed on the rear side of the connecting rod 5. The front end of the switch sleeve 4 passes through the mounting groove 2 and is rotatably connected to a rotating handle 7. A linkage mechanism 8 is also movably installed on the side of the cabinet door 1 close to the mounting groove 2, and the linkage mechanism 8 and the three limiting mechanisms 3 are linked to each other;

[0026] The limiting mechanism 3 includes a limiting groove 31 and a guide rail 32. The limiting groove 31 is opened at the top, bottom and one side of the switch shaft sleeve 4. The guide rail 32 is fixedly installed in the middle of one side of the cabinet door 1 near the mounting groove 2. The guide rail 32 is provided with three and is arranged in a ring shape on the outside of the mounting groove 2. The inside of the guide rail 32 is fixedly connected to the limiting component 33. The end of the limiting component 33 passes through the guide rail 32 and is inserted into the inside of the limiting groove 31. The three groups of limiting mechanisms 3 arranged in a ring around the mounting groove 2 and arranged in an isosceles triangle provide a stable and balanced limiting installation for the switch shaft sleeve 4, ensuring that the position of the switch shaft sleeve 4 in the mounting groove 2 is accurate and firm. The limiting mechanism 3 cooperates with the limiting groove 31 on the switch shaft sleeve 4, and precise insertion is achieved through the limiting component 33 in the guide rail 32. The limit is set so that the installation and disassembly of the switch sleeve 4 have clear positioning and reliable fixing mode, which is convenient for operation and can effectively prevent the switch sleeve 4 from being displaced or loosened during use. The linkage mechanism 8 and the three limit mechanisms 3 are linked to each other, so that during operation, the three limit mechanisms 3 can be synchronized by operating the linkage mechanism 8 only, thereby improving the efficiency and convenience of disassembly and assembly of the switch sleeve 4. The rotating handle 7 facilitates the operation and control of the isolating switch 6, and the connecting rod 5 ensures the effective connection and transmission between the switch sleeve 4 and the isolating switch 6. The overall structural design is reasonable and the functions are complete, which not only ensures the stability and safety of the switch operation of the explosion-proof control cabinet, but also improves its convenience and efficiency during installation, disassembly and use.

[0027] refer to Figure 3-Figure 4When the cam 332 is in the unlock state, the cam 333 is locked and the locking cam 332 is locked, so the cam 333 is locked. The operation is more precise and reliable. The limit block 333 is connected to the telescopic spring 331 through the slide rod 332. When the switch sleeve 4 is inserted into the installation groove 2, the telescopic spring 331 resets and drives the slide rod 332 to move outward, so that the limit block 333 is inserted into the inner side of the limit groove 31, thereby achieving effective limit fixation of the switch sleeve 4. This design is not only simple and convenient to operate, but also can provide a reliable fixing effect, preventing the switch sleeve 4 from loosening or displacement during use, thereby ensuring the normal operation and safety of the switch operating mechanism of the explosion-proof control cabinet. At the same time, when disassembly is required, it is only necessary to slide the slide rod 332 again to drive the limit block 333 out of the limit groove 31, which facilitates the maintenance and inspection of the equipment.

[0028] refer to Figure 1 、 Figure 3 and Figure 4The linkage mechanism 8 includes a mounting member 81 and a first articulated wheel 82. The mounting members 81 are arranged in a ring at equal intervals and are fixedly installed on one side of the cabinet door 1 near the mounting groove 2. The cabinet door 1 is installed with a slip ring 83 through the mounting member 81. The slip ring 83 is arranged in a ring on the side near the cabinet door 1 and is rotatably connected to the second articulated wheel 84. The second articulated wheel 84 is arranged corresponding to the guide rail 32. The first articulated wheel 82 is rotatably connected to the outer side of the slide rod 332 near one end of the mounting groove 2. A push rod 85 is fixedly connected between the first articulated wheel 82 and the second articulated wheel 84. The middle part of the side of the slip ring 83 away from the cabinet door 1 is rotatably connected to a handle 86. The outer surface of the handle 86 is fixedly connected to an anti-slip handrail cover. The mounting members 81 are arranged in a ring and fixed on one side of the cabinet door 1, providing a stable installation foundation for the slip ring 83, ensuring the firmness and position accuracy of the installation of the slip ring 83. The second articulated wheel 84 arranged and rotatably connected is set corresponding to the guide rail 32, and cooperates with the first articulated wheel 82 and the push rod 85 to form an effective linkage transmission system. When operation is required, by turning the handle 86, the slip ring 83 is driven to rotate, and then the second articulated wheel 84 pushes the push rod 85, driving the first articulated wheel 82 to rotate, thereby realizing the sliding action of the slide rod 332 in the guide rail 32. This design makes it possible to synchronously control the three limit mechanisms 3 only by operating the handle 86, greatly improving the convenience and efficiency of operation. The anti-slip handrail cover on the outer surface of the handle 86 increases friction, which is convenient for the operator to hold and operate, prevents hand slippage, and improves the safety and stability of operation. The overall linkage mechanism 8 is cleverly designed, making the disassembly and assembly of the switch sleeve 4 simpler and faster, and also improves the practicality and reliability of the switch operating mechanism of the entire explosion-proof control cabinet.

[0029] refer to Figure 1 and Figure 3The mounting member 81 includes a mounting plate 811, which is arranged in a ring shape with equal intervals and is arranged on the side of the cabinet door 1 close to the mounting groove 2. The mounting plate 811 is arranged on the outside of the mounting groove 2 on the cabinet door 1. A support rod 813 is fixedly installed on the side of the mounting plate 811 away from the cabinet door 1. An arc-shaped sliding frame 814 is fixedly installed on the end of the support rod 813. The slip ring 83 is slidably connected to the inner side of the arc-shaped sliding frame 814. Mounting holes 812 are opened at equal intervals on the side of the mounting plate 811 away from the cabinet door 1. The mounting holes 812 pass through the mounting plate 811. Countersunk hexagonal bolts 815 are provided inside the mounting holes 812. The mounting plate 811 is installed on the cabinet door 1 through the countersunk hexagonal bolts 815. The mounting plates 811 are arranged in a ring shape with equal intervals and are arranged on the side of the cabinet door 1 close to the mounting groove 2 and on its outside, providing a reasonable layout space and stable installation for the entire linkage mechanism 8. The positioning basis, the support rod 813 connects the mounting plate 811 and the arc-shaped sliding frame 814. The arc-shaped sliding frame 814 provides a precise sliding track for the slip ring 83, so that the slip ring 83 can slide stably on its inner side, ensuring the smoothness and accuracy of the operation of the linkage mechanism 8. The mounting hole 812 and the countersunk hexagonal bolt 815 design on the mounting plate 811 not only facilitate the fixed installation of the mounting plate 811 on the cabinet door 1, but also the use of the countersunk hexagonal bolt 815 makes the mounting surface smoother and more beautiful, while also reducing the interference of the bolt head on the movement of other components. This structural design not only ensures the firm connection between the linkage mechanism 8 and the cabinet door 1, but also provides reliable support and guidance for the movement of the slip ring 83, thereby improving the performance and reliability of the switch operating mechanism of the entire explosion-proof control cabinet, and making the disassembly and assembly operation of the switch sleeve 4 smoother and more efficient.

[0030] refer to Figure 2 The overall side shape of the rotating handle 7 is set in an L shape, and the outer edges and corners of the rotating handle 7 and the cabinet door 1 are set to be arc-shaped. The L-shaped side of the rotating handle 7 has good ergonomic design advantages. This shape is convenient for the operator to hold and apply force naturally and comfortably with his hands during use, making the operation of the disconnector 6 more convenient and labor-saving. The rotating handle 7 and the outer edges and corners of the cabinet door 1 are set to be arc-shaped. On the one hand, it can effectively avoid injuries to personnel due to accidental collisions with sharp edges during operation, thereby improving safety during use; on the other hand, the arc-shaped design is visually more beautiful and soft, and is coordinated with the design style of the overall equipment. At the same time, it also reduces the risk of damage due to stress concentration at the edges and corners, extends the service life of the equipment, and improves the comprehensive performance and user experience of the entire explosion-proof control cabinet switch operating mechanism.

[0031] When the locking cam 333 is in the unlocked position, the locking cam 333 is in the unlocked position, and the locking cam 333 is locked, so that the locking cam 333 is locked. The inner portion of the limit block 333 and the limit groove 31 are inserted into each other to limit the position of the switch sleeve 4 and to achieve a stable installation. Similarly, when disassembly is required, it is only necessary to adjust the slide bar 332 again to squeeze the telescopic spring 331 so that it contracts into the guide rail 32, causing the limit block 333 to disengage from the limit groove 31. At this time, the switch sleeve 4 can be easily removed from the inner portion of the installation groove 2. It can be seen that the present device is extremely convenient in the disassembly, assembly and maintenance of the switch sleeve 4 and the entire disconnector 6, which greatly improves the efficiency of maintenance work.

[0032] By setting the linkage mechanism 8, when the switch sleeve 4 in the installation groove 2 needs to be disassembled and assembled during use of the device, the operator can push the slip ring 83 to rotate inside the arc-shaped sliding frame 814 by holding the handle 86. At this time, as the slip ring 83 rotates, the second articulated wheel 84 will be driven to rotate along with the slip ring 83. During the rotation of the second articulated wheel 84, the push rod 85 will be adaptively pushed, thereby driving the first articulated wheel 82 to rotate. When the push rod 85 pushes the first articulated wheel 82, it can drive the sliding rod 332 to slide toward the inner side of the guide rail 32. Through the sliding of the sliding rod 332, on the one hand, the telescopic spring 331 will be squeezed to contract, and on the other hand, the movement of the sliding rod 332 can limit the The block 333 is pulled out from the limit groove 31. In this case, the switch sleeve 4 can be smoothly removed from the installation groove 2 or installed inside the installation groove 2. It can be seen that when the device needs to be disassembled and repaired, it is only necessary to pull the handle 86 to synchronously adjust the three limit mechanisms 3 to work in conjunction. As a whole, it can not only realize the function of rapid disassembly and maintenance, but also, during use, since the use of a threaded connection is avoided, it can effectively avoid the thread being clogged by dust or the phenomenon of thread slippage due to rust. This design greatly improves the convenience of using the device, brings a better experience to users in actual operation and maintenance, and further improves the practicality and reliability of the device.
