As shown in fig. 1 and fig. 2, a combined low-voltage draw-out type switch cabinet, a plurality of superposed placing plates 2 for placing electric appliances are arranged in a cabinet body 1, four lifting columns 311 are arranged at four corners in the cabinet body 1, a vertical rack 4 and a vertical fixing column 5 are arranged in the cabinet body 1,
the lower end surfaces of the plurality of placing plates 2 are respectively provided with a lifting device 3 for placing plates, the lifting device 3 for placing plates comprises a lifting limiting device 31 and a transmission device 32, the lifting limiting devices 31 are positioned at the left end part and the right end part of the placing plates 2 and are matched with the lifting columns 311 to prevent the placing plates 2 from descending due to gravity;
As shown in fig. 3, the lifting column 311 is provided with a pawl 3111,
the lifting limiting device 31 comprises a limiting device 312 positioned in a limiting device placing shell 316, a horizontal moving rack 313 fixedly connected with the limiting device 312 through a compression spring 6, wherein the horizontal moving rack 313 is connected with the limiting device placing shell 316 in a sliding way and can move left and right in the limiting device placing shell 316;
the gear teeth on the horizontal moving rack 313 are meshed with the transmission gear 314, the transmission gear 314 is fixedly sleeved on the transmission rod 315, and the transmission rod 315 fixedly penetrates through the limiting device placing shell 316 through a bearing, so that the transmission rod 315 can drive the transmission gear 314 to rotate relative to the limiting device placing shell 316, namely, the left and right movement of the horizontal moving rack 313 is realized;
and the limiting device 312 comprises a limiting plate 3121 and a limiting pawl 3122, the limiting pawl 3122 is hinged to the limiting device placing housing 316 through a pin, the limiting plate 3121 is located at the left side of the limiting pawl 3122, the right rotation angle of the limiting pawl 3122 is limited, the left end portion of the limiting pawl 3122 is engaged with the pawl 3111, and the right end surface is fixedly connected with the compression spring 6.
As shown in fig. 4 and 5, the pulley 323 is rotatably fixed to a left end portion of the transmission housing 322 by a wheel shaft, and the gear 321 is rotatably fixed to a right end portion of the transmission housing 322 by a wheel shaft, that is, the wheel shaft of the gear 321 is fixed to pass through the transmission housing 322 by a bearing, and the wheel shaft of the gear 321 is fixedly connected to a motor shaft of the rotating motor.
Because there are two lifting columns 311 located at the left end of the cabinet 1, which are located at the front end and the rear end of the cabinet 1, respectively, the number of the lifting limiting devices 31 at the left end of the placing plate 2 is two, but the two lifting limiting devices 31 are fixedly connected through one transmission rod 315, so that the rotation of one transmission rod 315 can simultaneously limit the interiors of the two lifting limiting devices 31 connected with the two lifting columns 311; similarly, two elevation restricting devices 31 are provided at the right end portion of the placing plate 2.
And the wheel axle lever on the transmission device 32 located at the middle part of the placing plate 2 passes through the transmission device placing shell 322 through the bearing and then extends to the front end part of the cabinet body 1 and is fixedly connected with the motor shaft of the rotating motor fixed on the front end surface of the placing plate 2, so that the rotating motor drives the wheel axle lever to rotate, and then the rotation of the gear 321 is realized.
When the device is used, the rotating motor fixedly connected with the gear 321 and positioned on the front end face of the placing plate 2 is started firstly, so that the gear 321 rotates clockwise, the gear 321 is meshed with the vertical rack 4, and the left end part of the transmission device 32 is in sliding connection with the vertical fixed column 5 through the pulley 323, so that the transmission device 32 can drive the placing plate 2 to move upwards;
since the pawl 3111 on the lifting column 311 is engaged with the limit pawl 3122 on the lifting limiting device 31, according to the ratchet engagement principle, after the placing plate 2 moves up, the placing plate 2 can easily move up continuously because the engagement of the pawl can only move towards one direction; in summary, when different placing plates 2 need to move up to different positions, different lifting displacements can be realized by starting the rotating motors on the different placing plates 2.
When the placing plate 2 is required to move downwards, the ratchet wheel can only move towards one direction due to the meshing principle of the ratchet wheel, and the downwards movement can be realized only by breaking the meshing.
Because the left end of the limit pawl 3122 on the lifting limiting device 31 limits the rotation angle of the limit pawl 3122 through the limit plate 3121, the right end surface controls the position of the limit pawl 3122 through the movable horizontal moving rack 313; therefore, when the engagement is released, the transmission rod 315 is directly and manually rotated, so that the transmission gear 321 is rotated clockwise, the horizontal moving rack 313 is moved rightward, and then the limit pawl 3122 (the limit pawl 3122 is hinged to the limiting device placing case 316 through the pin shaft) is pulled by the compression spring 6 to be rotated rightward, so that the engagement is released, and the placing plate 2 can be moved downward.
Therefore, before the placing plate 2 is moved downwards, the transmission rod 315 needs to be rotated clockwise, after the engagement between the pawl 3111 and the limiting pawl 3122 is broken, the rotating motor is started, so that the gear 321 rotates anticlockwise, the placing plate 2 is moved downwards under the action of the transmission device 32, after the placing plate 2 is moved downwards to a certain position, the transmission rod 315 needs to be rotated anticlockwise, so that the limiting pawl 3122 and the pawl 3111 are engaged again, the downward movement of the placing plate 2 is prevented, and the placing plate 2 is placed at a specific position.
In summary, the lifting of the placing board 2 is transmitted by the transmission device 32, and the position is fixed by the lifting limiting device 31.
After the displacement movement of the placing plate 2 is completed, the drawer unit is placed on the placing plate 2 through the slide rail.
Ratchet, defined as a gear with a rigid toothed or friction surface on its outer or inner edge, is an important component that constitutes a ratchet mechanism. The ratchet is driven by a pawl to move in steps, and the meshing motion is characterized in that the ratchet can only rotate in one direction and cannot rotate reversely.
The rack is a special gear with teeth distributed on the strip-shaped body. The rack is also divided into a straight rack and a helical rack which are respectively matched with a straight cylindrical gear and a helical cylindrical gear; the tooth profile of the rack is a straight line rather than an involute (plane for the tooth surface), which corresponds to a cylindrical gear with a reference circle radius of infinity.
The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above technical features are combined in particular, and also covers other technical solutions in which the above technical features or their equivalent features are combined arbitrarily without departing from the inventive concept. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
