Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0024] Embodiment

[0025] Combined with Figures 1 to 4 , this embodiment provides a door closing interlocking mechanism, including an interlocking base frame 1, a limit plate 2, and a driving plate 3. The driving plate 3 is rotatably hinged and arranged on the interlocking base frame 1, and is provided with a pressing part 4 and a transmission part 5. The limit plate 2 is arranged on the interlocking base frame 1 through an elastic part 6, and is provided with a lock tongue part 7. After being pressed, the pressing part 4 correspondingly drives the transmission part 5 to move, so as to trigger the limit plate 2 to press the elastic part 6 to move, so that its lock tongue part 7 switches from the initial position to the avoidance position. The interlocking base frame 1, the limit plate 2, and the driving plate 3 are all configured as sheet metal parts.

[0026] In the above interlocking mechanism, by directly arranging the pressing part 4 and the transmission part 5 on the driving plate 3 of the same structure, the unlocking operation can be completed only through a simple pressing action (after closing the cabinet door). The operation process is simple and fast. In the initial state, the lock tongue part 7 of the limit plate 2 automatically stays in the locked position to prevent the chassis truck from moving, providing additional safety protection. The unlocking can only be triggered after the pressing part 4 is pressed, so the locking can be released only after the cabinet door is closed, further improving the safety of the switch cabinet.

[0027] In particular, the interlocking base frame 1, the limit plate 2, and the driving plate 3 are all configured as sheet metal parts, ensuring that the whole structure is firm and durable, capable of withstanding high-frequency operations and external force impacts. The limit plate 2 is connected to the interlocking base frame 1 through the elastic part 6, providing a stable locking and unlocking mechanism. Through simple operation, high safety, strong reliability, low maintenance cost and wide application range, it ensures convenient use in various usage scenarios.

[0028] Such as Figure 2As shown, in this embodiment, a hinge seat 8 extends upward and bends in the middle of the interlock base frame 1. The drive plate 3 is strip-shaped, and its end is connected to the hinge seat 8 through a hinge shaft. On the one hand, the strip-shaped design provides sufficient lever force, enabling the pressing action to be accurately transmitted to the transmission part 5, thereby achieving accurate switching and unlocking operations. On the other hand, the connection between the hinge seat 8 and the hinge shaft ensures the stable rotation of the drive plate 3, avoiding inaccurate operations caused by structural looseness.

[0029] Among them, the pressing part 4 is correspondingly formed at the front end of the drive plate 3, and the pressing part 4 is configured as a flexible roller structure. Thus, the flexible roller structure reduces the friction during operation, makes the pressing action smoother, and improves the convenience and comfort of operation.

[0030] Among them, the transmission part 5 is integrally formed below the drive plate 3 and is adjacent to the end. The limiting plate 2 is correspondingly provided with a clamping groove 10 that abuts against the transmission part 5. The clamping groove 10 on the limiting plate 2 precisely abuts against the transmission part 5, enabling the transmission part 5 to effectively drive the limiting plate 2 to move, realizing the switching of the locking tongue part 7, and ensuring the high efficiency and reliability of the transmission process.

[0031] In this embodiment, when the locking tongue part 7 of the limiting plate 2 is in the initial position, the drive plate 3 is obliquely arranged on the interlock base frame 1. After an external force is pressed on the pressing part 4, the drive plate 3 rotates to be horizontal with the interlock base frame 1, correspondingly triggering the transmission part 5 to act on the clamping groove to drive the locking tongue part 7 of the limiting plate 2 to switch to the avoidance position. By pressing the pressing part 4 with an external force (i.e., closing the cabinet door), the rotation of the drive plate 3 and the movement of the limiting plate 2 can be realized, and the operation is simple and intuitive.

[0032] It should be understood that when the locking tongue part 7 is in the initial position, the external screw is correspondingly locked to prevent its rotation from driving the chassis truck to move, ensuring the stability of the electrical appliances in the switch cabinet. When the locking tongue part 7 switches to the avoidance position, the corresponding unlocking enables the screw to drive the chassis after rotating externally.

[0033] As Figure 2 and Figure 3 shown, in this embodiment, the limiting plate 2 is horizontally arranged on the interlock base frame 1, and the locking tongue part 7 is arranged in front of the interlock base frame 1, and the elastic member 6 is arranged behind the interlock base frame 1. The elastic member 6 is arranged at the back, and it can quickly return to its original position after the pressing is released, realizing the automatic reset function, and improving the convenience and safety of the device.

[0034] Further, the elastic member 6 is sleeved on the rear section of the limiting plate 2 and abuts against the rear side wall of the interlocking base frame 1. An opening for accommodating the reciprocating movement of the locking tongue portion 7 is correspondingly formed on the front side wall of the interlocking base frame 1. Among them, the elastic member 6 provides effective support and elasticity between the limiting plate 2 and the rear side wall of the interlocking base frame 1, reducing the sway of the limiting plate 2 and improving the stability of the device. In addition, the opening design enables the locking tongue portion 7 to reciprocate smoothly within the interlocking base frame 1, reducing the risk of friction and jamming, and improving the fluency and reliability of the operation.

[0035] In this embodiment, a guiding groove 9 for guiding the transmission portion 5 to move along a preset path is provided at the bottom of the interlocking base frame 1. Obviously, the guiding groove 9 provides a clear movement path, ensuring that the transmission portion 5 moves along a predetermined route during operation, reducing errors and deviations.

[0036] In addition, this embodiment further provides a chassis truck, which includes a vehicle body (not shown in the figure) and a plurality of the above-mentioned door closing interlocking mechanisms configured on the vehicle body. Obviously, the interlocking base frame 1 is installed and configured at a position corresponding to the cabinet door of the vehicle body, and correspondingly presses its driving plate 3 after the cabinet door is closed to trigger the switching movement of the limiting plate 2.

[0037] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention.
