Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet and its operating lever structure. Background Technology

[0002] Currently, the molded case circuit breakers in low-voltage distribution cabinets are installed on the cabinet frame or in the drawer functional unit. The circuit breaker is opened and closed by an operating mechanism installed on the circuit breaker. The operation of the operating mechanism needs to be achieved by extending the operating rod to the cabinet door panel and rotating the handle mounted on the door panel. Rotating the opening and closing handle realizes the opening and closing of the circuit breaker.

[0003] However, currently, the rotation center of the control handle and the rotation center of the circuit breaker operating mechanism are often not on the same line during manufacturing and assembly, which makes it difficult to open and close the circuit. In many cases, the circuit is closed by forcing the malfunction to close, which greatly damages the performance and lifespan of the product. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a power distribution cabinet and its operating lever structure that have good practicality and extended service life.

[0005] The technical solution adopted in this utility model is: an operating lever structure for a power distribution cabinet, comprising:

[0006] The connecting plate has movable connecting brackets on both sides;

[0007] Several linkage rods are respectively arranged on both sides of the connecting plate and respectively fixedly connected to the connecting frame;

[0008] The connecting plate has several limiting members on both sides that restrict the connecting frame from moving in one direction, and the displacement trajectories of the connecting frames on both sides are perpendicular to each other.

[0009] The linkage rod adopts a square shaft.

[0010] The connecting frame has a mounting hole at its center for inserting the end of the linkage rod.

[0011] The connecting frame is provided with mounting ears on its side, and fasteners are provided between the linkage rod and the mounting ears to connect the two.

[0012] A gasket is also provided between the linkage rod and the mounting ear.

[0013] The limiting members on each side of the connecting plate are located on both sides of the linkage rod. The connecting frame has a strip groove on both sides of the linkage rod. The limiting member has a cylindrical part that matches the size of the strip groove and a boss part with an outer diameter larger than the strip groove.

[0014] The limiting component is made of rivets.

[0015] A power distribution cabinet includes a cabinet body, a circuit breaker, an operating mechanism, and a handle, and also includes an operating lever structure as described above, wherein the operating lever structure is linked to the handle and the operating mechanism.

[0016] The beneficial effects of this utility model are: the operating lever structure in this technical solution can automatically compensate for the misalignment of the coupling amount, so that even if the center of the handle and the center of the operating mechanism are not concentric, it can still be operated flexibly, which has the advantages of good practicality and extended service life.

[0019] Figure 3 This is a breakdown diagram of the control lever structure. Detailed Implementation

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0021] As shown in the figure, an operating lever structure for a power distribution cabinet includes:

[0022] Connecting plate 1, with movable connecting brackets 2 on both sides;

[0023] Several linkage rods 3 are respectively arranged on both sides of the connecting plate 1 and respectively fixedly connected to the connecting frame 2;

[0024] The connecting plate 1 has several limiting members 4 on both sides that restrict the connecting frame 2 to move in one direction. The displacement trajectories of the connecting frames 2 on both sides are perpendicular to each other. The operating lever structure in this technical solution can automatically compensate for the misalignment of the coupling amount, so that the center of the handle and the center of the operating mechanism can still be operated flexibly even if they are not aligned. It has the advantages of good practicality and extended service life.

[0025] If the handle center and the operating mechanism are not concentric during assembly, the two linkage shafts are connected to the handle center and the operating mechanism respectively. The two linkage shafts will automatically adjust to make them concentric as well. In this way, when the handle drives the operating mechanism through the operating lever structure, it will not get stuck or blocked, which can greatly extend the service life and improve the smoothness of operation.

[0026] The linkage axis can be adjusted in both the X and Y axes, accommodating any situation where the handle center and the operating mechanism are not concentric.

[0027] The linkage rod 3 adopts a square shaft, and the center of the connecting frame 2 is provided with a mounting hole 5 for inserting the end of the linkage rod 3. The mounting hole is a square hole, and the cooperation between the square shaft and the square hole can realize the linkage action between various parts.

[0028] The connecting frame 2 has a mounting ear 6 on its side, and a fastener 7 is provided between the linkage rod 3 and the mounting ear 6 to connect the two. The fastener uses bolts to firmly connect the linkage rod and the connecting frame together.

[0029] A gasket 8 is also provided between the linkage rod 3 and the mounting ear 6, which uses elastic deformation to offset the decrease in preload caused by vibration or thermal expansion and contraction, and prevents the bolt from loosening.

[0030] The limiting member 4 on each side of the connecting plate 1 is provided on both sides of the linkage rod 3. The connecting frame 2 is provided with a strip groove 9 on both sides of the linkage rod 3. The limiting member 4 is provided with a cylindrical part 41 that matches the size of the strip groove 9 and a boss part 42 with an outer diameter larger than the strip groove 9. The cylindrical part and the strip groove can slide together. The boss part can prevent the connecting frame from detaching from the connecting plate, ensuring that the connecting frame will only slide along a straight line.

[0031] The limiting component 4 is made of rivets, which are installed on the connecting plate by riveting to ensure the working stability of the connecting frame.

[0032] A power distribution cabinet includes a cabinet body 10, a circuit breaker 11, an operating mechanism 12, and a handle 13. It also includes an operating lever structure as described above, wherein the operating lever structure is linked to the handle 13 and the operating mechanism 12, and has all the beneficial effects of the above-described operating lever structure.
