In the present invention, the power distribution cabinet 10 further includes a cabinet door control mechanism 400 (as shown in fig. 1 and fig. 2), and the cabinet door 200 is disposed on the cabinet body 100 through the cabinet door control mechanism 400 (as shown in fig. 8).
Next, a specific structure of the cabinet door control mechanism 400 is explained:
as shown in fig. 9, the cabinet door control mechanism 400 includes: a housing 410, a first component 420, and a second component 430. A partition plate 411 is disposed inside the housing 410, and the first component 420 and the second component 430 are respectively disposed at two sides of the partition plate 411.
As shown in fig. 10, 11 and 12, the first component 420 includes: a cabinet door rotating shaft 421, a bouncing rotating shaft 422, a first gear 423 and a first spring 424.
The cabinet door rotating shaft 421 rotates on the housing 410, the cabinet door rotating shaft 421 has a cabinet door connecting end 421a located outside the housing 410 and a movable connecting end 421b located inside the housing 410, the cabinet door connecting end 421a is fixedly connected with the cabinet door 200, the movable connecting end 421b is connected with a bouncing rotating shaft 422 key inside the housing 410, the first gear 423 rotates to be sleeved on the cabinet door rotating shaft 421, the first spring 424 is used for providing elastic force pressing the bouncing rotating shaft 422 on the first gear 423, and the bouncing rotating shaft 422 is connected with the first gear 423 through a one-way ratchet 425.
As shown in fig. 10, 11 and 12, the second assembly 430 includes: a pressing knob 431, a second gear 432, and a second spring 433.
The pressing knob 431 is rotatably arranged on the shell 410, the pressing knob 431 is provided with a pressing end 431a positioned outside the shell 410 and a rotating end 431b positioned in the shell 410, the rotating end 431b is in key connection with a second gear 432 in the shell 410, a limiting lug 431c is arranged on the pressing knob 431, a limiting groove 412 matched with the limiting lug 431c is formed in the inner side wall of the shell 410, a second spring 433 is used for providing elastic force for the pressing knob 431 so that the limiting lug 431c is pressed on the inner side wall of the shell 410, and the second spring 433 is also used for providing elastic force for the second gear 432 to be pressed on the separation blocking piece 411.
The cabinet door control mechanism 400 further includes an intermediate gear 440 rotatably disposed in the housing 410, and the first gear 423 and the second gear 432 are respectively engaged with the intermediate gear 440.
Here, it is to be noted that the movable connection end 421b is keyed with the bouncing rotation shaft 422 in the housing 410, and the "keyed connection" is intended to illustrate: on one hand, the movable connection end 421b and the bouncing rotation shaft 422 can be driven by the connection mode to rotate, and on the other hand, the movable connection end 421b and the bouncing rotation shaft 422 can also realize the mutual displacement motion in the axis direction by the connection mode. Similarly, the rotating end 431b is keyed to the second gear 432 in the housing 410, and this "keying" is the same way and is active.
The operation principle of the cabinet door control mechanism 400 with the above structure is explained as follows:
the process of opening the cabinet door 200 is,
the cabinet door 200 rotates around the cabinet body 100 under the action of external force (as shown in fig. 2, the rotating shaft of the cabinet door 200 is parallel to the horizontal plane), the cabinet door 200 further drives the cabinet door rotating shaft 421 connected with the cabinet door rotating shaft to rotate, the cabinet door rotating shaft 421 drives the whole bouncing rotating shaft 422 to smoothly rotate forward in a key connection mode with the bouncing rotating shaft 422 through the movable connecting end 421b, when the cabinet door 200 rotates to a certain angle, the external force action is cancelled, due to the limiting action of the one-way ratchet 425, the bouncing rotating shaft 422 cannot rotate reversely, the bouncing rotating shaft 422 further limits the reverse rotation of the cabinet door rotating shaft 421 in the key connection mode, therefore, the cabinet door 200 cannot rotate reversely and is closed again under the action of gravity, and the cabinet door 200 stays at the current position;
the points are explained here:
one point is as follows: because the bouncing rotating shaft 422 is connected with the first gear 423 through the one-way ratchet 425, the bouncing rotating shaft 422 can only rotate in one direction (for example, clockwise), the rotation in the opposite direction (for example, counterclockwise) is limited by the one-way ratchet 425, and the direction in which the bouncing rotating shaft 422 can rotate is just met in the process of opening the cabinet door 200;
secondly, the method comprises the following steps: the bouncing spindle 422 reciprocates (similar to bouncing) along the axial direction thereof in cooperation with the first spring 424 to achieve rotation in one direction (e.g., clockwise) to escape the one-way ratchet 425;
three points are as follows: although the first gear 423 is rotatably sleeved on the cabinet door rotating shaft 421, the first gear 423 cannot freely rotate due to the action of other components; as will be analyzed, the first gear 423 is meshed with the intermediate gear 440, the intermediate gear 440 is meshed with the second gear 432, the second gear 432 is connected by a key and is subjected to resistance of the rotating end 431b of the pressing knob 431, the pressing knob 431 is subjected to the elastic force of the second spring 433, so that the limiting projection 431c is clamped in the limiting groove 412, and the pressing knob 431 needs to be unlocked to rotate freely, and it is known whether the first gear 423 can rotate freely or not, and whether the limiting projection 431c on the pressing knob 431 is separated from the limiting groove 412 or not is required to be determined;
the process of closing the cabinet door 200 is,
firstly, one hand of an operator applies an axial force to the pressing end 431a of the pressing knob 431, so that the limiting lug 431c on the pressing knob 431 is separated from the limiting groove 412, and at the moment, the pressing knob 431, the second gear 432, the intermediate gear 440, the first gear 423, the bouncing rotating shaft 422 and the cabinet door rotating shaft 421 are in a rotatable free state;
next, the other hand of the operator applies an opposite direction acting force to the cabinet door 200, the cabinet door 200 directly drives the cabinet door rotating shaft 421 to rotate, the cabinet door rotating shaft 421 drives the bouncing rotating shaft 422 to rotate through a key connection, the bouncing rotating shaft 422 drives the first gear 423 to rotate through the one-way ratchet 425, the first gear 423 drives the intermediate gear 440 to rotate through a meshing manner, the intermediate gear 440 drives the second gear 432 to rotate through a meshing manner, and the second gear 432 drives the pressing knob 431 to rotate through a key connection, so that the cabinet door 200 can rotate in the opposite direction to be closed;
after the cabinet door 200 is closed, the operator cancels the axial force applied to the pressing knob 431, and the limiting protrusion 431c is clamped in the limiting groove 412 again under the elastic force of the second spring 433; even if the limiting protrusion 431c is not completely clamped in the limiting groove 412, the limiting protrusion 431c is finally completely clamped in the limiting groove 412 under the transmission fit of a series of connecting components as long as a rotating force is applied to the cabinet door 200 to slightly rotate the cabinet door 200 by a small angle;
here, the points to be specifically explained are: when one hand of an operator applies axial force to the pressing end 431a of the pressing knob 431, the limiting bump 431c on the pressing knob 431 can be separated from the limiting groove 412, the pressing knob 431 moving axially can also apply axial force to the second gear 432 through the second spring 433, so that the second gear 432 and the separation blocking piece 411 generate a larger friction force, the second gear 432 is not easy to rotate and is influenced by the friction force, and all the mutually connected components are not easy to rotate, so that even if the other hand of the operator does not touch the cabinet door 200, the cabinet door 200 is not easy to rotate under the action of gravity, the cabinet door 200 is prevented from being smashed down heavily under the action of gravity, and the operation safety can be effectively ensured.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
