Description

Technical Field

[0001] This utility model relates to an easy-to-install integrated primary and secondary circuit breaker, belonging to the field of power equipment technology. Background Technology

[0002] Traditional circuit breakers are mainly used in industrial production to protect circuit connections and automatically disconnect lines when loads or short circuits occur. Their main functions are to cut off and connect load circuits and disconnect faulty circuits to prevent accidents from escalating and ensure safe operation. With the development of modern technology, electrical circuits have become more complex, so the functions of circuit breakers used in them have also been improved to better meet the needs of modern production.

[0003] Chinese Patent Publication No. (CN 216980431 U) discloses a primary and secondary integrated circuit breaker, including a circuit breaker base. Three support springs are equidistantly fixed to one side of the inner wall of the circuit breaker base. A metal contact base is fixed to the top of each of the three support springs. Each of the four corners of the top of the three metal contact bases has a locking hole. A first connecting shaft is fixed to the middle position of one side of each of the three metal contact bases. This utility model discloses a primary and secondary integrated circuit breaker. After the connecting support is installed, the second connecting shaft at its upper end will press against the metal contact base inside the circuit breaker base. This causes the first connecting shaft to be compressed under the deformation of the support springs. Simultaneously, the compression compresses the metal connector at the bottom of the circuit breaker base, connecting the circuit. Furthermore, the metal connector, under the action of the torsion spring and the support frame, has a compressive force against the first connecting shaft, ensuring full contact and reducing the risk of detachment during long-term use, thereby improving the practicality of the device.

[0004] In the above-mentioned device, the circuit breaker and the circuit breaker base are installed relatively fixedly. When the circuit breaker needs to be disassembled for maintenance or repair after long-term use, the disassembly and assembly of the circuit breaker is relatively difficult and often requires a lot of time and effort, making the disassembly and installation cost of the circuit breaker relatively high. Therefore, it is not convenient for operators to perform convenient maintenance.

[0005] Therefore, a primary and secondary integrated circuit breaker that is easy to install is proposed. Utility Model Content

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides a primary and secondary integrated circuit breaker that is easy to install, including a circuit breaker base 1, a mounting plate 3 on the top of the circuit breaker base 1, a circuit breaker body 4 fixedly mounted on the top of the mounting plate 3, a mounting bracket 5 fixedly mounted on the front side of the circuit breaker base 1, and insertion holes 7 on both the left and right sides of the mounting plate 3. A mounting mechanism 2 is provided on the surface of the circuit breaker base 1, the mounting mechanism 2 including a motor 201 and connecting rods 204. Two connecting rods 204 are movably connected to the left and right sides of the inner cavity of the circuit breaker base 1, and mounting blocks 205 are fixedly mounted on the surfaces of both connecting rods 204. Six mounting blocks 205 are also fixedly mounted. The other end of each of the six connecting rods 206 is movably connected to a connecting rod 206. The outer side of each of the six connecting rods 206 is movably connected to a movable plate 207. The outer side of each of the two movable plates 207 is fixedly installed with a plug rod 208. The motor 201 is fixedly installed on the front side of the mounting bracket 5. The output end of the motor 201 is fixedly connected to a drive gear 202. The front side of the circuit breaker base 1 is movably connected to a driven gear 203. The front sides of the two connecting rods 204 are fixedly installed on the rear side of the drive gear 202 and the driven gear 203. The dimensions of the drive gear 202 and the driven gear 203 are matched, and the surface of the drive gear 202 meshes with the surface of the driven gear 203.

[0030] By setting up the installation mechanism 2, the output of the motor 201 causes the connecting rod 204 to drive the connecting rod 206 to swing. At this time, the moving plate 207 pushes the plug rod 208 to move, so that the plug rod 208 fixes the mounting plate 3 and the circuit breaker body 4. This installation method can quickly disassemble and assemble the mounting plate 3 and the circuit breaker body 4, reducing the time and cost of disassembling and assembling the mounting plate 3 and the circuit breaker body 4, and making it convenient for operators to perform maintenance work on the circuit breaker body 4.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, guide rods 209 are fixedly installed on both the left and right sides of the bottom of the inner cavity of the circuit breaker base 1. The four guide rods 209 are slidably connected to the inner surfaces of the two movable plates 207. Slots 210 are provided on both the left and right sides of the circuit breaker base 1. Six insert rods 208 pass through the six slots 210 and the inner cavities of the six mounting brackets 5 and extend to the outer side of the mounting plate 3. The inner cavities of the six insert rods 208 and the inner cavities of the six mounting brackets 5 are in the same horizontal direction, and the inner cavities of the insert rods 208 and the inner cavities of the mounting brackets 5 are interconnected. Slots 211 are provided on both the left and right sides of the surface of the circuit breaker base 1. The inner side of the mounting plate 3 is slidably connected to the inner cavities of the two slots 211. A base plate 6 is fixedly installed at the bottom of the circuit breaker base 1. Mounting bolts 8 are threadedly connected to both the left and right sides of the surface of the base plate 6.

[0033] By setting the guide rod 209, the movement direction of the moving plate 207 can be limited to prevent the moving plate 207 from deviating during movement, thus affecting the disassembly and assembly of the circuit breaker body 4. By setting the slot 210, the movement of the insertion rod 208 can be limited to prevent the insertion rod 208 from changing direction during movement, thus affecting the disassembly and assembly of the circuit breaker body 4. By setting the slot 211, the mounting plate 3 and the circuit breaker body 4 can be snapped onto the outside of the circuit breaker base 1, thereby facilitating the fixing of the mounting plate 3 and the circuit breaker body 4 by the insertion rod 208. By setting the mounting bolt 8, the entire equipment can be installed, making it easy to install the entire equipment to the required position according to the usage requirements.

[0034] When this utility model is in operation: when it is necessary to disassemble the circuit breaker body 4, the output of the motor 201 causes the driving gear 202 and the driven gear 203 to cooperate, driving the connecting rod 204 to rotate. At this time, the mounting block 205 rotates in the circumferential direction, causing the connecting rod 206 to swing, causing the moving plate 207 to move the insertion rod 208 inward, and then pulling the mounting plate 3 forward, so that the inner side of the mounting plate 3 moves out of the inner cavity of the slot 211, completing the disassembly of the mounting plate 3 and the circuit breaker body 4. After the circuit breaker body 4 is disassembled and maintained, the mounting plate 3 is snapped onto the outside of the circuit breaker base 1. Then, through the reverse output of the motor 201, the driven gear 203 and the driving gear 202 drive the connecting rod 204 to rotate in the opposite direction. At this time, the mounting block 205 rotates in the opposite direction synchronously. With the cooperation of the connecting rod 206, the moving plate 207 pushes the insertion rod 208 to move outward, so that the insertion rod 208 passes through the inner cavity of the mounting frame 5, completing the installation of the mounting plate 3 and the circuit breaker body 4.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
