DETAILED DESCRIPTION

[0021] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0022] Example

[0023] like Figure 1-Figure 4 As shown: 10KV switch cabinet five-protection locking mechanism, including: switch cabinet 1 is an indispensable part of the power system. The main function of the switch cabinet 1 is to provide a closed environment to protect the internal electrical components from the external environment, while preventing personnel from directly contacting high-voltage components, thereby ensuring the safe operation of the power system.

[0024] Inside the switch cabinet 1, we see an important component - the circuit breaker body 2. The circuit breaker body 2 is fixed inside the switch cabinet 1. Its main function is to automatically cut off the circuit when the current exceeds a certain limit, thereby preventing circuit overload and possible fire. This automatic cut-off function makes the circuit breaker body 2 play a key protective role in the power system.

[0025] A connecting door 3 is provided in the middle of the switch cabinet 1. The design of this door allows the staff to easily access the internal circuit breaker body 2 for necessary inspection and maintenance. A hinge 4 is installed on one side of the connecting door 3, so that the door can be opened and closed flexibly. At the same time, a rotary button 5 is provided on the other side of the connecting door 3. This button is used to control the opening and closing of the door, providing additional safety and convenience.

[0026] An emergency button assembly 6 is also provided in the middle of the connecting door 3. The emergency button assembly 6 can be activated in an emergency to quickly cut off the current of the circuit breaker body 2, thereby preventing possible electrical accidents. This design enhances the reaction speed of the device in dealing with emergencies and further improves the safety of the power system.

[0027] It can be understood that: a handle 7 is provided on one side of the connecting door 3. The handle 7 is an important element on the connecting door 3, which not only provides a convenient door opening and closing operation, but also is the installation basis of other key components.

[0028] A connection slot 301 is provided on one side of the handle 7. The main purpose of the connection slot 301 is to install the emergency button assembly 6. The emergency button assembly 6 can be quickly activated in an emergency to cut off the current or initiate other emergency measures. By installing it in the connection slot 301 on the handle 7, it can be ensured that in an emergency, the operator can quickly and conveniently find and press the emergency button, thereby minimizing potential dangers.

[0029] A second connection slot 302 is provided on the other side of the handle 7. The main function of the second connection slot 302 is to install the rotary button 5. The rotary button 5 is usually used to control the opening and closing of the connection door 3. By installing it in the second connection slot 302, it can be ensured that the rotary button 5 does not affect the normal use of the handle 7, providing a convenient operation experience.

[0030] The operation of the connecting door 3 is more convenient and user-friendly, and also ensures a quick response in an emergency. The handle 7, as an integrated part of the connecting door 3, organically combines the emergency button assembly 6 and the rotary button 5 through reasonable layout and design, forming a complete and efficient operation interface.

[0031] It is understandable that the emergency button assembly 6 is mainly composed of a rectangular base 601, which is the support base of the entire assembly. The rectangular base 601 is stable and strong, and can ensure the stability and reliability of the assembly in various environments.

[0032] A connection cover 602 is provided on one side of the rectangular base 601. The function of the connection cover 602 is to protect the internal mechanical components from the influence of the external environment and provide a necessary operation interface. Through the connection cover 602, the operator can easily press the emergency button to trigger the corresponding safety measures.

[0033] A connecting shaft 603 is provided inside the rectangular base 601. The connecting shaft 603 is a key component in the emergency button assembly 6, and it plays a role in connecting and transmitting power. When the operator presses the emergency button, the connecting shaft 603 will rotate accordingly, thereby triggering subsequent mechanical actions.

[0034] A ball rod 604 is provided inside the connecting shaft 603. A spring 605 is provided at one end of the ball rod 604, and the other end is connected to the connecting shaft 603. Under normal circumstances, the spring 605 applies a certain pressure to the ball rod 604 to keep it in a stable position. When the emergency button is pressed, the rotation of the connecting shaft 603 drives the ball rod 604 to move, thereby compressing the spring 605.

[0035] During the movement of the ball head rod 604, it will contact the first gear 606. The first gear 606 meshes with a set of second gears 607 to form a gear transmission system. When the ball head rod 604 moves, it will push the first gear 606 to rotate, and then drive the second gear 607 to rotate together. The function of this gear transmission system is to convert the operator's action of pressing the emergency button into mechanical power to drive subsequent safety measures.

[0036] It is understandable that the fixed connection between the second gear 607 and the concave connecting plate 608 ensures the stability and synchronization between the two, so that when the second gear 607 rotates, the concave connecting plate 608 can move accordingly.

[0037] A sliding block 609 is provided inside the concave connecting plate 608. The sliding block 609 can slide inside the concave connecting plate 608, and this design enables it to move freely within a certain range while maintaining close contact with the concave connecting plate 608.

[0038] A second ball head rod 610 is provided inside the sliding block 609. The second ball head rod 610 is connected to the sliding block 609 and can move inside the sliding block 609. This design enables the second ball head rod 610 to perform corresponding actions as the sliding block 609 moves when the emergency button is pressed.

[0039] A second spring 611 is provided on one side of the second ball head rod 610. One end of the second spring 611 is connected to the second ball head rod 610, and the other end is tightly pressed on the concave connecting plate 608. This pressing method enables the second spring 611 to apply a certain pressure to the second ball head rod 610, thereby maintaining its stability in a normal state.

[0040] The rotation of the connecting shaft 603 drives the first gear 606 and the second gear 607 to rotate. As the second gear 607 rotates, the concave connecting plate 608 also moves accordingly. In this process, the sliding block 609 slides inside the concave connecting plate 608 and drives the second ball head rod 610 to move. This movement process compresses the second spring 611, causing it to deform.

[0041] It can be understood that the second ball head rod 610 is a key component, which includes a rotating ball head 612, a left connecting rod 613 and a right connecting rod 614. These three parts together constitute the second ball head rod 610 and realize connection and interaction with other components.

[0042] The rotating ball head 612 is designed to rotate inside the sliding block 609. This design allows the second ball head rod 610 to move flexibly in different directions to accommodate various actions when the emergency button is pressed. The rotating connection of the rotating ball head 612 ensures smooth interaction between it and the sliding block 609, reducing friction and resistance, thereby improving the response speed and efficiency of the system.

[0043] One end of the left connecting rod 613 is fixedly connected to one side of the rotating ball head 612. The other end of the left connecting rod 613 is plugged into one end of the ball head rod 604. This connection method ensures the stability and synchronization between the left connecting rod 613 and the ball head rod 604. When the emergency button is pressed, the movement of the ball head rod 604 will drive the left connecting rod 613 to perform corresponding actions, thereby triggering subsequent safety measures.

[0044] Corresponding to the left connecting rod 613, the other end of the rotating ball head 612 is fixedly connected to one end of the right connecting rod 614. The right connecting rod 614 is longer than the left connecting rod 613. This design difference enables the right connecting rod 614 to be moved and adjusted in a wider range. This flexibility enables the second ball head rod 610 to adapt to the operation requirements in different situations, thereby improving the adaptability and reliability of the entire system.

[0045] The working process of the utility model is as follows: when emergency processing is required, the ball head rod is first rotated to drive the first gear to rotate, and the rotation of the first gear drives the second gear to rotate, and at the same time the concave connecting plate rotates, and then the second ball head rod is plugged in through the ball head rod, and at the same time the second ball head rod can rotate, and the second spring limits the sliding block to maintain stable operation.

[0046] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
