The inner wall of the movable cavity has protrusions that are evenly distributed. The bottom of each docking block is fixedly connected with a connecting pin that matches the slot and the movable cavity. Both sides of the connecting pin are fixedly connected with locking blocks that match the limiting grooves and the movable cavity. The outer side of each locking block is embedded with a spring piece that matches the protrusion.
[0006] The present invention, as described above, is used for a modular direct-acting circuit breaker.

[0012] In summary, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model adopts a modular circuit breaker structure design. The circuit breakers designed in this scheme can be assembled and combined to form new models of circuit breakers, or they can be used independently. This allows the circuit breakers to be applied in different working scenarios, meet various working needs, provide users with more and more flexible choices, and provide convenience for users' work.
[0014] 2. This utility model, through the setting of groove, protrusion three, and rotating disk, and the rotating disk is also provided with protrusion two adapted to protrusion three, so that when the rotating disk rotates, protrusion three will create a certain resistance to the rotating disk, requiring the user to apply a certain force to rotate the rotating disk. In this way, the rotation of the rotating disk can be limited, so that the rotating disk will not move arbitrarily when not being operated, thereby ensuring that the connecting pin will not move arbitrarily, improving the stability of the two circuit breakers after assembly, and providing convenience for the user's work and use.
[0015] 3. With the setting of the adapter block and the adapter groove, the connecting pin will be locked onto the adapter block after being inserted into the groove, and the adapter block will also be inserted into the adapter groove. In this way, the connecting pin can drive the rotating disk to rotate under the action of the adapter block, so that the rotating disk limits the rotation of the connecting pin, providing convenience for the user's work.
[0016] 4. This utility model, through the setting of the circuit breaker body and the slot, the slot is opened on the circuit breaker body and is used to install the docking block. In this way, after the docking block is assembled onto the circuit breaker body, the circuit breaker body can achieve modular combination through the docking block and all the structures on the docking block, so that it can be assembled into various different models to meet actual use needs and provide convenience for users' work and use.
[0017] 5. This utility model features a positioning groove and a positioning block. The positioning groove is located on the mating block, and the positioning block is fixed to the circuit breaker body. Therefore, when the mating block and the circuit breaker body are assembled, the positioning block will be inserted into the positioning groove to achieve positioning of the mating block, which provides convenience for users in subsequent assembly work and for users in their work and use.
[0018] 6. This utility model, through the setting of a socket, a sliding groove, and a sliding block, uses the sliding block to connect and fix the docking block and the circuit breaker body together. After the docking block is snapped onto the circuit breaker body, under the action of the spring, the sliding block will move out of the sliding groove and snap into the socket on the circuit breaker body, thereby fixing the docking block and the circuit breaker body and improving the firmness and tightness of the connection between the docking block and the circuit breaker body. Specifically, when snapping the docking block, the inner wall of the circuit breaker body will first squeeze the sliding block into the sliding groove and compress the spring at the same time. After the docking block is adjusted into place, the sliding block will pop out of the sliding groove and snap into the socket for fixation, providing convenience for users' work and use.
[0019] 7. This utility model incorporates a spring to keep the sliding block stationary within the socket. After the connecting block is attached to the circuit breaker body, the spring's push ensures the sliding block remains locked within the socket, thus guaranteeing the tightness and stability of the connection between the connecting block and the circuit breaker body, providing convenience for users.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0028] A modular direct-acting circuit breaker includes multiple docking blocks 1. The top of each docking block 1 has a slot 2. The bottom of the inner cavity of the slot 2 has a movable cavity 3. Both sides of the inner cavity of the slot 2 have limiting grooves 4 that communicate with the movable cavity 3. The inner wall of the movable cavity 3 has protrusions 5 that are evenly distributed. The bottom of each docking block 1 is fixedly connected with a connecting pin 6 that is adapted to the slot 2 and the movable cavity 3. Both sides of the connecting pin 6 are fixedly connected with locking blocks 7 that are adapted to the limiting grooves 4 and the movable cavity 3. The outer side of the locking block 7 is embedded with a spring piece 8 that is adapted to the protrusion 5.
[0029] The specific usage process is as follows: First, attach the docking block 1 to the corresponding circuit breaker body 21. During installation, insert the docking block 1 vertically. During this process, the positioning block 10 will engage with the corresponding positioning groove 9 to position the docking block 1. Then, one side of the docking block 1 will be inserted into the slot 11. Continue pushing the docking block 1 in until the sliding block 14 is engaged and fixed in the socket 12. The sliding block 14 is used to connect and fix the docking block 1 and the circuit breaker body 21 together. After the docking block 1 is attached to the circuit breaker body 21, under the action of the spring 15, the sliding block 14 will move out of the sliding groove 13 and engage with the socket 12 on the circuit breaker body 21, thereby fixing the docking block 1 and the circuit breaker body 21 and raising the docking block 1. The connection between the connecting block 1 and the circuit breaker body 21 ensures a secure and tight fit. When the connecting block 1 is engaged, the inner wall of the circuit breaker body 21 first presses the sliding block 14 into the sliding groove 13, simultaneously compressing the spring 15. After the connecting block 1 is in place, the sliding block 14 pops out of the sliding groove 13 and engages with the socket 12 for fixation, providing convenience for the user. The spring 15 is used to hold the sliding block 14 in place within the socket 12. After the connecting block 1 is engaged with the circuit breaker body 21, the sliding block 14 remains engaged within the socket 12 under the push of the spring 15. This ensures a secure and tight connection between the connecting block 1 and the circuit breaker body 21, providing convenience for the user. It should be noted that the circuit breaker body 21 also... The circuit breaker can be used as a standalone circuit breaker without the installation of the connecting block 1. In this case, the circuit breaker bodies 21 can be combined for use. For example, if a longer circuit breaker is needed, the user can first position the circuit breaker body 21 with the connecting block 1 installed vertically, and then control the connecting pin 6 on the connecting block 1 to insert into the slot 2 on another connecting block 1 until the end of the connecting pin 6 is inserted into the movable cavity 3. Simultaneously, the locking block 7 on the connecting pin 6 slides down into the movable cavity 3 within the corresponding limiting groove 4. At the same time, the adapter block 20 will also engage with the adapter groove 18. After the connecting pin 6 is inserted into the groove 16, it will engage with the adapter block 20, and the adapter block 20 will also be inserted into the adapter groove 18. Thus, the connecting pin 6 can engage with the adapter block 20. Under the action of the rotating disk 19, the rotating disk 19 limits the rotation of the connecting pin 6, providing convenience for the user's work. Then, rotating the connecting pin 6 drives the locking block 7 to move within the movable cavity 3. During this process, the protrusion 5 and the spring piece 8 will match and create resistance to the movement of the locking block 7. At this time, the user needs to rotate the connecting pin 6 forcefully until the two circuit breaker bodies 21 are aligned in the same direction to complete the installation. Under the pressure of the protrusion 5, the spring piece 8 will first be compressed into the locking block 7, and then pop out after moving to the gap between the two protrusions 5, and then be compressed into the locking block 7 again. This process is repeated until the two circuit breaker bodies 21 are installed in place, so that the circuit breaker can form multiple combined use modes while ensuring the basic function of the circuit breaker.This design provides users with more flexible options and convenience. The rotating disk 19 is also equipped with a protrusion 1 that matches the protrusion 3 17. When the rotating disk 19 rotates, the protrusion 3 17 will obstruct its rotation, requiring the user to apply a certain amount of force to rotate it. This limits the rotation of the rotating disk 19, preventing it from moving freely when not in use. This also ensures that the connecting pin 6 does not move freely, improving the stability of the assembled two circuit breakers and providing convenience for users. It should be noted that during design and production, the position of the locking block 7 should be parallel to the circuit breaker body 21 so that the two circuit breaker bodies 21 can be matched together after the mating block 1 rotates at a certain angle.
[0030] Therefore, by adopting a modular circuit breaker structure design, the circuit breakers designed in this scheme can be assembled and combined to form new models of circuit breakers, or they can be used independently. This allows the circuit breakers to be applied in different working scenarios, meet various working needs, provide users with more and more flexible choices, and provide convenience for users' work.
[0031] The bottom of the inner cavity of the active cavity 3 is provided with a groove 16, and a rotating disk 19 is rotatably installed at the bottom of the inner cavity of the groove 16. The surface of the rotating disk 19 is fixedly connected with uniformly distributed protrusions 2, and the inner wall of the groove 16 is fixedly connected with uniformly distributed protrusions 3 17 that are adapted to the protrusions 2.
[0032] Specifically, the groove 16, the protrusion 17, and the rotating disk 19 are designed such that the rotating disk 19 also has a protrusion 2 that matches the protrusion 17. When the rotating disk 19 rotates, the protrusion 17 will obstruct the rotating disk 19 to a certain extent, requiring the user to apply a certain force to rotate the rotating disk 19. This limits the rotation of the rotating disk 19, preventing it from moving arbitrarily when not in use. This also ensures that the connecting pin 6 will not move arbitrarily, improving the stability of the two circuit breakers after assembly and providing convenience for the user's work.
[0033] The top of the rotating disk 19 is fixedly connected to an adapter block 20, and the bottom of the connecting pin 6 is provided with an adapter groove 18 that matches the adapter block 20.
[0034] Specifically, the adapter block 20 and adapter slot 18 are configured such that after the connecting pin 6 is inserted into the groove 16, it will engage with the adapter block 20, and the adapter block 20 will also be inserted into the adapter slot 18. In this way, the connecting pin 6 can drive the rotating disk 19 to rotate under the action of the adapter block 20, so that the rotating disk 19 limits the rotation of the connecting pin 6, providing convenience for the user's work.
[0035] One side of the docking block 1 is engaged with the circuit breaker body 21, and the side of the circuit breaker body 21 facing the docking block 1 has a slot 11 that is adapted to the docking block 1.
[0036] Specifically, the circuit breaker body 21 and the slot 11 are designed so that the slot 11 is formed on the circuit breaker body 21 and is used to install the docking block 1. After the docking block 1 is assembled onto the circuit breaker body 21, the circuit breaker body 21 can be modularly combined through the docking block 1 and all the structures on the docking block 1, so that it can be assembled into various different models to meet actual use needs and provide convenience for users' work.
[0037] The docking block 1 has positioning grooves 9 on both sides, and the slot 11 has positioning blocks 10 that are adapted to the positioning grooves 9 fixedly connected to both sides of the inner cavity.
[0038] Specifically, the positioning slot 9 and the positioning block 10 are designed such that the positioning slot 9 is opened on the docking block 1, and the positioning block 10 is fixed on the circuit breaker body 21. Therefore, when the docking block 1 and the circuit breaker body 21 are assembled, the positioning block 10 will be inserted into the positioning slot 9 to achieve the positioning of the docking block 1, which provides convenience for the user's subsequent assembly work and for the user's work and use.
[0039] The card slot 11 has insertion holes 12 on both sides of its inner cavity, and the docking block 1 has sliding grooves 13 on both sides. The sliding groove 13 has a sliding block 14 that is adapted to the insertion hole 12.
[0040] Specifically, the socket 12, sliding groove 13, and sliding block 14 are designed to connect and fix the docking block 1 and the circuit breaker body 21 together. After the docking block 1 is engaged with the circuit breaker body 21, the sliding block 14 will move out of the sliding groove 13 and engage with the socket 12 on the circuit breaker body 21 under the action of the spring 15, thereby fixing the docking block 1 and the circuit breaker body 21 and improving the firmness and tightness of the connection between the docking block 1 and the circuit breaker body 21. When engaging the docking block 1, the inner wall of the circuit breaker body 21 will first squeeze the sliding block 14 into the sliding groove 13 and compress the spring 15. After the docking block 1 is adjusted into place, the sliding block 14 will pop out from the sliding groove 13 and engage with the socket 12 for fixation, providing convenience for users.
[0041] A spring 15 is fixedly connected to one side of the sliding block 14, and the end of the spring 15 away from the sliding block 14 is fixedly connected to the inner wall of the sliding groove 13.
[0042] Specifically, the spring 15 is designed to keep the sliding block 14 locked in the socket 12. After the connecting block 1 is locked onto the circuit breaker body 21, the sliding block 14 will always be locked in the socket 12 under the push of the spring 15. This ensures the tightness and firmness of the connection and assembly between the connecting block 1 and the circuit breaker body 21, providing convenience for users.
[0043] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
