[0002] A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions and can close, carry, and break the current under abnormal circuit conditions within a specified time. According to its installation method, it is usually divided into plug-in, fixed, and drawer-type circuit breakers.

[0003] When disassembling and maintaining the circuit breaker, since a large amount of heat is generated during the operation of the circuit breaker, the external plastic shell is prone to heat accumulation, causing burns to maintenance personnel. Moreover, the internal blocking chip is also a high-heat component, and the integrity of the structure of the blocking chip must be ensured, which causes great inconvenience to the disassembly and installation of maintenance personnel. Therefore, it is necessary to design a relatively safe and flexible disassembly device to meet the requirements of safe disassembly. Summary of the Utility Model

Specific embodiments

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0026] Embodiment 1

[0027] Referring to Figure 1-2 , for the first embodiment of the present utility model, this embodiment provides a plug-in circuit breaker, including,

[0028] Frame mechanism 100, the frame mechanism 100 includes an outer shell 101, a bracket 106 is fixedly connected to the bottom of the outer shell 101, and a first alignment groove 104 is opened in the outer shell 101;

[0029] The first alignment groove 104 is provided with a disassembly and assembly mechanism 200 in a matching manner. The disassembly and assembly mechanism 200 includes a shaft rod 201. The side surface of the shaft rod 201 is rotatably connected to the top of the bracket 106. A roller 211 is fixedly sleeved on the outer surface of the shaft rod 201. And a first rocker arm 202 is rotatably connected to the end surface of the shaft rod 201. The first rocker arm 202 is hinged to a transmission rod 204 through a plug shaft. A vertical spring 205 is fixedly connected to the side surface of the transmission rod 204. A side rod 206 is fixedly connected to the end surface of the vertical spring 205. The outer side surface of the side rod 206 is slidably connected to a limit frame 207.

[0030] Specifically, the fixed connection between the housing 101 and the bracket 106 makes the bracket 106 have a better stabilizing effect on the disassembly and assembly mechanism 200. The opening of the first alignment groove 104 allows the storage element 102 to be flexibly installed, meeting the storage requirements for the on-off data of the circuit breaker. The fixed sleeving of the shaft rod 201 and the roller 211 can help the storage element 102 adjust the angle and be stably stored in the inner cavity of the housing 101, avoiding the jitter, scratching, and bumping of the storage element 102 during installation. The transmission cooperation among the shaft rod 201, the first rocker arm 202, and the transmission rod 204 can transmit the torque to the vertical spring 205, and then convert the rotational motion into the stretching of the vertical spring 205. At the same time, it can also help the side rod 206 reciprocate in the inner cavity of the limit frame 207, enabling the first rocker arm 202 and the second rocker arm 209 to rotate continuously. Finally, the storage element 102 and the heat dissipation bottom plate 103 can be accurately installed into the housing 101 according to the angle. The installation and disassembly functions of this device are efficient and accurate, and at the same time, it meets the assembly requirements of the circuit breaker.

[0031] Furthermore, a pin shaft 208 is fixedly connected to the surface of the limit frame 207. The lower surface of the pin shaft 208 is rotatably connected to a second rocker arm 209. The inner side surface of the second rocker arm 209 is rotatably connected to a secondary straight rod 210. A transmission wheel 212 is fixedly sleeved on the outer surface of the secondary straight rod 210.

[0032] Preferably, the rotational connection between the pin shaft 208 and the second rocker arm 209 enables the vertical spring 205 to transmit the stretching energy again. Then, the synchronous rotation of the second rocker arm 209 and the first rocker arm 202 will drive the vertical spring 205 to stretch. Since the vertical spring 205 is an energy storage part, the energy stored during stretching can be released into the torque required for rotation, and the first rocker arm 202 and the second rocker arm 209 can continue to rotate. This combined structure can meet the installation requirements of precision devices such as the storage element 102. The fixed sleeving of the secondary straight rod 210 and the transmission wheel 212 enables the secondary straight rod 210 to rotate independently.

[0033] In use, first fixedly connect the bracket 106 to the bottom of the housing 101. Then, open the first alignment groove 104 in the housing 101. Next, rotatably connect the shaft rod 201 to the top of the bracket 106. Assemble the first rocker arm 202 and the transmission rod 204 with the shaft rod 201 in the order of rotational transmission. Then, fixedly install the upright spring 205 on the side of the transmission rod 204. Fix the side rod 206 to the end face of the upright spring 205 and slidably sleeve it on the limit block 207. After that, assemble the pin shaft 208, the second rocker arm 209, and the secondary straight rod 210 in sequence according to the transmission order of "shaft - arm - rod". Finally, fixedly sleeve the transmission wheel 212 on the outside of the secondary straight rod 210.

[0034] In summary, the fixed sleeving of the shaft rod 201 and the roller 211 can help the storage element 102 adjust the angle and be stably stored in the inner cavity of the housing 101, avoiding jitter, scratching, and bumping during the installation of the storage element 102. The transmission cooperation of the shaft rod 201, the first rocker arm 202, and the transmission rod 204 can transmit the torque to the upright spring 205, and then convert the rotational motion into the stretching of the upright spring 205. At the same time, it can also help the side rod 206 reciprocate in the inner cavity of the limit frame 207, enabling the first rocker arm 202 and the second rocker arm 209 to rotate continuously. Finally, the storage element 102 and the heat dissipation bottom plate 103 can be accurately installed into the housing 101 according to the angle. The installation and disassembly functions of this device are efficient and accurate.

[0035] Embodiment 2

[0036] Refer to Figure 2-3 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides related parts for realizing the self - rotation effect of the roller 211.

[0037] Specifically, a connecting rod kit 213 is fixedly connected to the outer surface of the transmission wheel 212. A support rod 214 is rotatably connected to the end face of the connecting rod kit 213. The side of the support rod 214 is fixedly connected to the roller 211.

[0038] Furthermore, the rotational cooperation of the connecting rod kit 213 with the transmission wheel 212 and the support rod 214 enables the three to form a stable lever member, which can allow the storage element 102 to flexibly adjust the angle and facilitate plug - in assembly.

[0039] Preferably, the storage element 102 is inserted into the top of the connecting rod kit 213, and the side of the storage element 102 is inserted into the first alignment groove 104.

[0040] Among them, the plug - in connection between the storage element 102 and the first alignment groove 104 makes the position of the storage element 102 more accurate during assembly and improves the installation efficiency of the device.

[0041] Afterwards, a second alignment groove 105 is formed on the side surface of the outer shell 101. A heat dissipation bottom plate 103 is inserted into the inner cavity of the second alignment groove 105. The heat dissipation bottom plate 103 is fixedly connected to the side surfaces of the roller 211 and the transmission wheel 212 through a top plate.

[0042] In the above, due to the stretching action of the upright spring 205, the moving directions of the roller 211 and the transmission wheel 212 are opposite to each other. As a result, when the heat dissipation bottom plate 103 is docked, the side surface is clamped and connected under the extrusion force. This method of docking using the extrusion force improves the problem of easy detachment during parallel docking.

[0043] During use, first, the heat dissipation bottom plate 103 is fixedly connected to the side surfaces of the roller 211 and the transmission wheel 212 through a top plate. Then, the heat dissipation bottom plate 103 is clamped with the second alignment groove 105 formed on the outer shell 101 to complete the flexible installation of the circuit breaker component. After that, the storage component 102 is inserted into the top of the link kit 213 and is inserted and installed with the first alignment groove 104.

[0044] In summary, through the rotational cooperation of the link kit 213 with the transmission wheel 212 and the support rod 214, the three form a stable lever component, which can flexibly adjust the angle of the storage component 102 and facilitate insertion and assembly. Through the insertion connection between the storage component 102 and the first alignment groove 104, the position of the storage component 102 is more accurate during assembly, improving the installation efficiency of the device.

[0045] Embodiment 3

[0046] Referring to Figure 2-4 , this is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving the stable transmission effect of the transmission rod 204.

[0047] Specifically, a stabilizing block 203 is fixedly connected to the outer surface of the shaft rod 201. The stabilizing block 203 is an integrally formed iron block, and the center of the stabilizing block 203 coincides with the center of the shaft rod 201.

[0048] Furthermore, since the stabilizing block 203 coincides with the center of the shaft rod 201, the shaft rod 201 rotates more stably, significantly improving the problem of rotational jitter. At the same time, the rotational amplitudes of the first swing arm 202 and the second swing arm 209 can be kept consistent, and the docking and installation of the storage component 102 are more stable.

[0049] Preferably, there are two sets of the transmission rod 204, the upright spring 205, the side rod 206, and the limiting frame 207. The two sets of the transmission rod 204, the upright spring 205, the side rod 206, and the limiting frame 207 are symmetrically arranged on the upper surface of the bracket 106.

[0050] Among them, the symmetrical arrangement of the two groups of transmission rods 204, upright springs 205, and side rods 206 enables the storage element 102 and the heat dissipation bottom plate 103 to maintain a stable and steady side during assembly, facilitating installation and disassembly and achieving the effect of "dual-purpose integration" of the device.

[0051] During use, first fixedly sleeve the stabilizing block 203 on the surface of the shaft rod 202, and then symmetrically arrange the two groups of transmission rods 204, upright springs 205, and side rods 206 and the limiting frame 207 on the upper surface of the bracket 106 for the stable installation of the storage element 102 and the heat dissipation bottom plate 103.

[0052] In summary, by keeping the stabilizing block 203 in line with the center of the shaft rod 201, the shaft rod 201 rotates more stably, significantly improving the problem of rotational jitter. At the same time, the rotation amplitudes of the first swing arm 202 and the second swing arm 209 can also be kept consistent, making the docking installation of the storage element 102 more stable.
