Description

Technical Field

[0001] This application relates to the field of electrical switch technology, specifically to a trip lock and circuit breaker. Background Technology

[0002] As a locking device, the core function of the trip lock is to physically lock electrical equipment in the tripped state to prevent accidental activation during maintenance or debugging and ensure operational safety.

[0003] In the prior art, the locking mechanism of a circuit breaker lock typically includes a lock cylinder and a transmission structure. The transmission structure keeps the electrical equipment open by means of blocking or other methods, while the rotation of the lock cylinder can drive the transmission structure to switch between locked and unlocked states.

[0004] In practical applications, circuit breaker locks typically have different functional requirements depending on the specific application scenario. For example, in some scenarios, the lock cylinder can be turned directly to unlock the circuit breaker. However, in other scenarios, to further enhance security and prevent accidental activation, the operating requirements stipulate that the unlocking process of the circuit breaker lock requires at least two steps. For instance, the circuit breaker button must be pressed first, and then the lock cylinder must be turned with the key to complete the unlocking. These settings are designed to prevent accidental operation.

[0005] However, different circuit breaker structures are usually required for the two different needs mentioned above, which not only reduces the versatility of the circuit breaker, but also increases the design and production costs.

[0006] Therefore, there is an urgent need to provide a gate opening lock structure that can improve the versatility of gate opening locks, enabling them to achieve different functional requirements through more minute adjustments, thereby reducing production and processing costs. Summary of the Invention

[0007] The purpose of this application is to provide a circuit breaker and a trip lock that can improve the versatility of the trip lock, enabling the trip lock to achieve different functional requirements through more minor adjustments, thereby reducing production and processing costs.

[0008] To achieve the above objectives, in a first aspect, this application provides a trip lock for locking a contact module in a tripped state. The trip lock includes a linkage module, a trip button, a lock cylinder, and a locking element. The linkage module is connected to the contact module and can lock or unlock the contact module in the tripped state. When the trip button is pressed, it can drive the contact module to switch between tripped and closed states. The lock cylinder includes a core and a lock plate. The core can drive the lock plate to move along a first direction to push the linkage module to switch between unlocked and locked states. The locking element is disposed in the movement direction of the lock plate and can abut against the lock plate and prevent the lock plate from moving along the first direction. When the trip button is pressed, it can push the locking element to move along a second direction to disengage from the lock plate. The second direction is angled to the first direction.

[0009] Based on the embodiments described above, when the contact module is in operation, without a trip lock, pressing the trip button can activate the contact module to open or close the circuit. With a trip lock in place, a key can be used to turn the lock cylinder, thereby switching between unlocked and locked states via the linkage module.

[0010] Building upon this, this application includes a separate locking element that abuts against the lock plate to prevent the lock plate from moving in the first direction, thereby preventing the lock plate from switching between unlocked and locked states. When opening the lock, the opening button is pressed first. The opening button pushes the locking element to move in the second direction and disengage from the lock plate. At this point, the locking element no longer obstructs the lock plate, and the lock cylinder can be turned with the key to open the lock. This design ensures that the opening button must be pressed before turning the lock cylinder, thus preventing accidental operation and improving security. Furthermore, since the locking effect on the lock plate is achieved separately through the locking element, in actual use, the installation of the locking element can be selected based on different usage requirements, thereby improving versatility and reducing production costs.

[0011] In summary, this application incorporates a locking mechanism, allowing users to choose whether or not to install it. Before installation, the lock cylinder can be opened directly by turning the key; after installation, the opening button must be pressed before turning the key to open the lock. Therefore, the locking mechanism enables the circuit breaker lock to meet diverse usage requirements, improving its versatility and allowing for more precise adjustments to achieve different functionalities, thus reducing production costs.

[0012] In some embodiments, the locking plate has a slot at the end opposite to the trip button along the second direction, with the slot opening facing the side opposite to the trip button. The locking member has a locking block at its end facing the second direction, which can engage in the slot to restrict movement of the locking plate along the first direction.

[0013] Based on the above embodiments of this application, by setting a slot and a block, the cooperation between the blocks achieves the blocking and restriction of the locking element on the locking plate. Simultaneously, the slot opening direction is opposite to the trip button along the second direction, so the block also engages with the slot from this direction. When the locking element needs to disengage from the locking plate, it is only necessary to make the two move relative to each other along the second direction to disengage the slot and the block. The overall structure is simple and the cooperation is stable and reliable.

[0014] In some embodiments, the end of the locking plate away from the trip button along the second direction is further provided with a guide surface, which is inclined and adjacent to the slot.

[0015] Based on the embodiments described above, by providing an inclined guide surface, the locking block can be better guided to slide out of the slot when the locking member disengages from the locking plate. Similarly, when the locking member and the support plate abut again, the locking block can be better guided to engage in the slot. This makes the fit between the locking member and the locking plate more stable and reliable.

[0016] In some embodiments, the lock cylinder includes a housing with a receiving cavity formed inside the housing, the core being disposed within the receiving cavity, and a lock plate being slidably disposed on the side of the housing. A limiting groove is provided on the bottom surface of the receiving cavity, a locking member is disposed within the limiting groove, and the locking member is slidable within the limiting groove in a second direction.

[0017] Based on the embodiments described above, a housing is provided to form a receiving cavity, which is used to install, accommodate, and protect the core and other structures, and also provides a mounting base for the sliding installation of the lock plate. The setting of the limiting groove facilitates the installation of the locking component and also limits the movement trajectory of the locking component, restricting the movement trajectory of the locking component to a second direction, making the contact and disengagement process between the locking component and the lock plate more stable and reliable.

[0018] In some embodiments, an elastic element is provided in the limiting groove, and the elastic element can be compressed when the trip button pushes the locking element to move in the second direction.

[0019] Based on the embodiments described above, when the trip button pushes the locking member to move, it compresses the elastic member. Subsequently, when the trip button is released, the elastic member releases and pushes the locking member to reset, ensuring that the locking member can stably maintain its blocking and limiting position on the locking plate during subsequent use. Simultaneously, when the trip button is not pressed, the elastic member can cooperate with the limiting groove to limit the locking member, preventing wobbling that could affect the engagement.

[0020] In some embodiments, a first push block is provided on the side of the trip button facing the locking member, and a second push block is provided on the end of the locking member near the trip button. When the trip button is pressed, the first push block can abut against the second push block and push the locking member to move in the second direction.

[0021] Based on the embodiments described above, when the trip button is pressed, the locking member is moved by the direct contact between the first push block and the second push block, thereby disengaging the locking member from the locking plate. The above-described structure is simple and the pushing process is stable and reliable.

[0022] In some embodiments, a first reset module is connected to the trip button, which is used to push the trip button to reset after the trip button is pressed.

[0023] Based on the above embodiments of this application, by setting a first reset module, the circuit breaker button can be pushed to reset after it is pressed. After the circuit breaker button is reset, the locking member will also be reset under the push of the elastic member. Therefore, in order to allow the locking member to disengage from the lock plate when the circuit breaker is opened, the circuit breaker button needs to be pressed continuously while the key is turned to rotate the lock cylinder, thereby further reducing the risk of accidental activation.

[0024] In some embodiments, the linkage module includes a first push rod, which can be pushed along a second direction when the trip button is pressed, and can directly or indirectly push the moving contact to move when the first push rod moves along the second direction.

[0025] Based on the above embodiments of this application, by setting a first push rod for linkage between the trip button and the contact module, when the trip button is pressed, the first push rod pushes the moving contact to move, thereby realizing the tripping and closing drive.

[0026] In some embodiments, the linkage module includes a first linkage rod, which is rotatably disposed on the side of the lock plate. When the lock plate moves in a first direction, it can push the first linkage rod to move. When the first linkage rod moves, it can directly or indirectly push the moving contact to move.

[0027] Based on the above embodiments of this application, by setting a first linkage rod for linkage between the lock cylinder and the contact module, when the key is pressed to turn the lock cylinder, the lock plate is driven to move in the first direction. When the lock plate moves, the moving contact is pushed to move through the first linkage rod to realize the opening and closing drive.

[0028] According to a second aspect of this application, a circuit breaker is provided, comprising a contact module and the aforementioned trip lock. The contact module includes a moving contact and a stationary contact, and the trip lock is used to lock the contact module in the open state.

[0029] Based on the above embodiments of this application, the circuit breaker provided by this application includes the aforementioned tripping lock. By setting a locking element, the user can choose whether to install the locking element as needed. Before the locking element is installed, the circuit breaker can be tripped directly by turning the lock cylinder with a key. After the locking element is installed, the tripping button must be pressed first, and then the lock cylinder must be turned with a key to trip the circuit breaker. Therefore, the setting of the locking element enables the tripping lock to meet different usage requirements, improves the versatility of the tripping lock, and allows different functional requirements to be achieved through more minor adjustments, thereby reducing production and processing costs.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this application, it should be noted that, unless otherwise stated, the terms "inner," "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In the prior art, the locking mechanism of a circuit breaker lock typically includes a lock cylinder and a transmission structure. The transmission structure keeps the electrical equipment open by means of blocking or other methods, while the rotation of the lock cylinder can drive the transmission structure to switch between locked and unlocked states.

[0045] In practical applications, circuit breaker locks typically have different functional requirements depending on the specific application scenario. For example, in some scenarios, the lock cylinder can be turned directly to unlock the circuit breaker. However, in other scenarios, to further enhance security and prevent accidental activation, the operating requirements stipulate that the unlocking process of the circuit breaker lock requires at least two steps. For instance, the circuit breaker button must be pressed first, and then the lock cylinder must be turned with the key to complete the unlocking. These settings are designed to prevent accidental operation.

[0046] However, different circuit breaker structures are usually required for the two different needs mentioned above, which not only reduces the versatility of the circuit breaker, but also increases the design and production costs.

[0047] Therefore, there is an urgent need to provide a gate opening lock structure that can improve the versatility of gate opening locks, enabling them to achieve different functional requirements through more minute adjustments, thereby reducing production and processing costs.

[0048] To address the aforementioned problems in the prior art, this application provides a trip lock for locking the contact module 1 in the tripped state. (Reference) Figures 1 to 5 As shown, the trip lock includes a linkage module 2, a trip button 3, a lock cylinder 4, and a locking member 5. The linkage module 2 is connected to the contact module 1 and can lock or unlock the contact module 1 in the tripped state. When the trip button 3 is pressed, it can drive the contact module 1 to switch between the tripped and closed states. The lock cylinder 4 includes a core 41 and a locking plate 42. The core 41 can drive the locking plate 42 to move along a first direction to push the linkage module 2 to switch between the unlocked and locked states. The locking member 5 is partially disposed in the movement direction of the locking plate 42 and can abut against the locking plate 42 and prevent the locking plate 42 from moving along the first direction. When the trip button 3 is pressed, it can push the locking member 5 to move along a second direction to disengage from the locking plate 42. The second direction is set at an angle to the first direction.

[0049] Based on the above embodiments of this application, when the contact module 1 is in operation, without the trip lock set, the trip button 3 can be pressed to drive the contact module 1 to open or close the circuit. When the trip lock is set, the key can be used to turn the lock cylinder 4, thereby switching between unlocked and locked states via the linkage module.

[0050] Based on this, a separate locking element 5 is provided in this application. The locking element 5 can abut against the lock plate 42 to prevent the lock plate 42 from moving in the first direction, thereby preventing the lock plate 42 from switching between the unlocked and locked states. When it is necessary to open the circuit breaker, first press the opening button 3. The opening button 3 pushes the locking element 5 to move in the second direction and disengage from the lock plate 42. At this time, the locking element 5 no longer blocks the lock plate 42, and the circuit breaker can be opened by turning the lock cylinder 4 with the key. Through the above settings, the circuit breaker must be opened by pressing the opening button 3 first and then turning the lock cylinder 4, thereby avoiding accidental operation and improving security. At the same time, since the locking effect of the lock plate 42 in this application is achieved by the locking element 5 alone, in actual use, the locking element 5 can be selected for installation according to different usage requirements, thereby improving versatility and reducing production and processing costs.

[0051] In summary, by incorporating locking element 5, users can choose whether or not to install it as needed. Before installation, the lock cylinder 4 can be opened directly by turning the key. After installation, the opening button 3 must be pressed before turning the key to open the lock cylinder 4. Therefore, the locking element 5 allows the lock to meet different usage requirements, improving its versatility and enabling different functional requirements to be achieved through minor adjustments, thereby reducing production costs.

[0052] Specifically, this application uses a separately provided locking element 5 to achieve the linkage between the trip button 3 and the lock cylinder 4, thereby achieving the technical effect that the lock cylinder 4 cannot be rotated to trip the circuit breaker when the trip button 3 is not pressed. In actual use, the specific structure of the contact module 1 can be set according to the actual situation and with reference to the existing technology; this application does not impose specific limitations on it.

[0053] Furthermore, in this application, the core 41 and the locking plate 42 can also be configured with any suitable linkage method. (Reference) Figure 1 and Figure 2 As shown in the exemplary embodiment of this application, a push rod is provided on the core 41, and a push groove is provided on the lock plate 42, with the push rod inserted into the push groove. When the key drives the core 41 to rotate, the lock plate 42 moves in the first direction through the cooperation of the push rod and the push groove.

[0054] In this application, the locking plate 42 and the locking member 5 can be configured with any suitable structure, and the mating structure between them can also be configured with any suitable structure according to the mating requirements. (See reference) Figures 2 to 4As shown, in an exemplary embodiment of this application, the end of the locking plate 42 facing away from the trip button 3 in the second direction may be provided with a slot 421, the opening of the slot 421 facing the side facing away from the trip button 3. The end of the locking member 5 facing the second direction may be provided with a locking block 51, which can be engaged in the slot 421 to restrict the movement of the locking plate 42 in the first direction.

[0055] Based on the above embodiments of this application, by setting a slot 421 and a block 51, the cooperation of the blocks 51 and the locking member 5 achieves the blocking and restriction of the locking plate 42 by the locking member 5. At the same time, the opening direction of the slot 421 is opposite to the trip button 3 along the second direction, so the block 51 is also engaged in the slot 421 from this direction. When the locking member 5 needs to disengage from the locking plate 42, it is only necessary to make the two move relative to each other along the second direction to disengage the slot 421 and the block 51. The overall structure is simple and the cooperation is stable and reliable.

[0056] Specifically, further reference Figure 2 As shown, to avoid the locking plate 42 from engaging with the locking member 5, and also to facilitate the locking plate 42 in pushing the linkage module 2, in some embodiments of this application, the end of the locking plate 42 along the second direction may be provided with a protruding pushing member, and a slot 421 is formed on the pushing member, and the slot 421 is provided along a third direction, which is perpendicular to the first direction and the second direction respectively. At this time, the locking block 51 provided at the end of the locking member 5 is also correspondingly provided along the third direction, so that the slot 421 and the locking block 51 can better engage.

[0057] Meanwhile, in order to ensure the strength of the pusher, in some embodiments of this application, the connection position between the pusher and the locking plate 42 may also be provided with a reinforcing rib or other structure. The specific configuration can be made according to the actual situation, and this application does not impose any specific restrictions on it.

[0058] Further, refer to Figure 2 As shown in some embodiments of this application, the end of the locking plate 42 away from the trip button 3 along the second direction may also be provided with a guide surface 422, which is inclined to the slot 421.

[0059] Based on the embodiments described above, by providing an inclined guide surface 422, the locking block 51 can be better guided to slide out of the slot 421 when the locking member 5 disengages from the locking plate 42. Similarly, when the locking member 5 abuts against the support plate again, the locking block 51 can be better guided to engage in the slot 421. This makes the fit between the locking member 5 and the locking plate 42 more stable and reliable.

[0060] Specifically, when the trip button 3 pushes the locking member 5, the locking member 5 moves in the second direction away from the locking member 5. At this time, when the key turns the core 41, it pushes the locking plate 42 to move in the first direction, that is, the locking plate 42 moves downward relative to the locking member 5. At this time, the setting of the guide surface 422 enables the locking member 5 to better guide the relative movement trajectory between the locking member 5 and the locking plate 42.

[0061] When the locking plate 42 needs to be reset again, the locking plate 42 locking block 51 abuts against the guide surface 422 and slides relative to it, so that the locking block 51 slides back into the locking groove 421, realizing the locking member 5 and the locking plate 42 contacting and limiting again.

[0062] The specific mating structure between the locking component 5 and the locking plate 42 has been disclosed above. Furthermore, to ensure a stable mating between the locking component 5 and the locking plate 42, their positions also need to be defined. (Reference) Figure 3 As shown in some embodiments of this application, the lock cylinder 4 includes a cover 43, with a receiving cavity 431 formed inside the cover 43. The core 41 is disposed within the receiving cavity 431, and the lock plate 42 is slidably disposed on the side of the cover 43. A limiting groove 432 is provided on the bottom surface of the receiving cavity 431, and a locking member 5 is disposed within the limiting groove 432, and the locking member 5 is slidable within the limiting groove 432 in a second direction.

[0063] Based on the above embodiments of this application, a housing 43 is provided to form a receiving cavity 431, which is used to install, accommodate, and protect the core 41 and other structures, and also provides an installation basis for the sliding installation of the locking plate 42. The setting of the limiting groove 432 not only facilitates the installation of the locking member 5, but also limits the movement trajectory of the locking member 5, restricting the movement trajectory of the locking member 5 to the second direction, making the contact and disengagement process between the locking member 5 and the locking plate 42 more stable and reliable.

[0064] Specifically, further reference Figure 3 As shown, the locking member 5 can be configured as a T-shaped structure, and the limiting groove 432 is correspondingly configured as a T-shaped structure. At the same time, a limiting shaft (not shown) can be inserted into the locking member 5 along a third direction, and a corresponding sliding groove is provided on the cover 43. The two ends of the limiting shaft are respectively inserted into the sliding groove and slidably connected to the cover 43, thereby realizing the limiting of the locking member 5.

[0065] Furthermore, in some embodiments of this application, an elastic element (not shown) may be provided in the limiting groove 432, which can compress the elastic element when the trip button 3 pushes the locking member 5 to move in the second direction.

[0066] Based on the above embodiments of this application, when the trip button 3 pushes the locking member 5 to move, it compresses the elastic member. Subsequently, when the trip button 3 is released, the elastic member releases and pushes the locking member 5 to reset, so that the locking member 5 can stably maintain its blocking and limiting effect on the locking plate 42 during subsequent use. At the same time, when the trip button 3 is not pressed, the elastic member can cooperate with the limiting groove 432 to limit the locking member 5, preventing shaking that may affect the cooperation.

[0067] In specific assembly, the elastic element can be set as an elastic structure such as a spring. When the elastic element is specifically set as a compression spring, the axial direction of the compression spring is set along the second direction. When the locking element 5 moves along the second direction under the push of the trip button 3, the compression spring is compressed. After the trip button 3 is released, the compression spring is released and pushes the locking element 5 to reset.

[0068] In this application, the trip button 3 can actuate the locking element 5 in any suitable manner. (See reference) Figure 4 As shown in an exemplary embodiment of this application, the opening button 3 is provided with a first push block 31 on the side facing the locking member 5, and the locking member 5 is provided with a second push block 52 at the end near the opening button 3. When the opening button 3 is pressed, the first push block 31 can abut against the second push block 52 and push the locking member 5 to move in the second direction.

[0069] Based on the above embodiments of this application, when the trip button 3 is pressed, the locking member 5 is pushed to move by the direct contact between the first push block 31 and the second push block 52, thereby disengaging the locking member 5 from the locking plate 42. The above configuration is simple in structure and the pushing process is stable and reliable.

[0070] In some embodiments of this application, a first reset module 6 is connected to the trip button 3. The first reset module 6 is used to push the trip button 3 to reset after the trip button 3 is pressed.

[0071] Based on the above embodiments of this application, by setting the first reset module 6, the circuit breaker button 3 can be pushed to reset after it is pressed. After the circuit breaker button 3 is reset, the locking member 5 will also be reset under the push of the elastic member. Therefore, in order to allow the locking member 5 to disengage from the lock plate 42 when the circuit breaker is opened, the circuit breaker button 3 needs to be pressed continuously while the key is turned on the lock cylinder 4, thereby further reducing the risk of accidental activation.

[0072] Furthermore, it should be noted that this application uses a locking element 5 to achieve the linkage between the trip button 3 and the lock cylinder 4, thereby achieving the technical effect that the lock cylinder 4 cannot be rotated to trip the circuit breaker if the trip button 3 is not pressed. As for the linkage module, any suitable setting can be selected with reference to existing technologies; this application does not impose specific limitations on it.

[0073] refer to Figure 5As shown in some embodiments of this application, the linkage module 2 may include a first push rod 21. When the trip button 3 is pressed, it can push the first push rod 21 in a second direction. When the first push rod 21 moves in the second direction, it can directly or indirectly push the moving contact to move.

[0074] Based on the above embodiments of this application, by setting a first push rod 21 for linkage between the trip button 3 and the contact module 1, when the trip button 3 is pressed, the first push rod 21 pushes the moving contact to move, thereby realizing the tripping and closing drive.

[0075] Meanwhile, in some embodiments of this application, the linkage module 2 includes a first linkage rod 22, which is rotatably disposed on the side of the locking plate 42. When the locking plate 42 moves in the first direction, it can push the first linkage rod 22 to move. When the first linkage rod 22 moves, it can directly or indirectly push the moving contact to move.

[0076] Based on the above embodiments of this application, by setting a first linkage rod 22 for linkage between the lock cylinder 4 and the contact module 1, when the key is pressed to turn the lock cylinder 4, the lock plate 42 is driven to move along the first direction. When the lock plate 42 moves, it pushes the moving contact to move through the first linkage rod 22, thereby realizing the opening and closing drive.

[0077] Based on the above technical solution, and according to the second aspect of this application, a circuit breaker is provided, with reference to... Figure 6 As shown, the circuit breaker includes contact module 1 and the aforementioned trip lock. Contact module 1 includes moving contacts and stationary contacts, and the trip lock is used to lock contact module 1 in the open state.

[0078] Based on the above embodiments of this application, the circuit breaker provided by this application includes the aforementioned tripping lock. By setting the locking element 5, the user can choose whether to install the locking element 5 as needed. Before the locking element 5 is installed, the circuit breaker can be tripped directly by turning the lock cylinder 4 with the key. After the locking element 5 is installed, the tripping button 3 needs to be pressed first, and then the lock cylinder 4 needs to be turned with the key to trip the circuit breaker. Therefore, the setting of the locking element 5 enables the tripping lock to meet different usage requirements, improves the versatility of the tripping lock, and allows different functional requirements to be achieved through more minor adjustments, thereby reducing production and processing costs.

[0079] Furthermore, it should be noted that the circuit breaker in this application is not limited to the components mentioned above. In actual use, other components, such as arc-extinguishing chambers, can be installed according to the usage requirements. The specific installation can be made according to the actual usage requirements, and this application does not impose any specific restrictions on this.
