Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some components of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product.
Referring to fig. 1 to 3, the drawout complete set of switch cabinet and the method for taking out the unit drawers thereof include a cabinet body 1, the cabinet body 1 is provided with a plurality of drawable unit drawers 1a, and on the basis of the above prior art, the present embodiment further includes a cabinet body 1 lifting mechanism 2, a longitudinal moving mechanism 3, a transverse pulling mechanism 4, a rotary unscrewing mechanism 5, a supporting mechanism 6, a positioning driving mechanism 7 and an extension frame 8.
As shown by arrows in fig. 1, 3, and 6, the horizontal direction and the vertical direction in the present embodiment respectively indicate the X, Y direction, and the lifting direction indicates the Z direction.
The lifting mechanism 2 is fixedly arranged on the cabinet body 1 and is used for driving the extension frame 8 fixedly arranged on the lifting seat of the lifting mechanism 2 to move. The longitudinal moving mechanism 3 is fixedly arranged on the extension frame 8 and is used for longitudinally moving the transverse pulling mechanism 4; a transverse pulling mechanism 4 fixedly mounted on the slide of the longitudinal moving mechanism 3 for transversely pulling out the unit drawer 1a which has been opened; the rotary unscrewing mechanism 5 is fixedly installed on the pushing seat of the transverse pulling mechanism 4, and is used for rotating the knob 1a1 of the unit drawer 1a, so that the unit drawer 1a is separated from the cabinet 1 in a clamping manner, and the knob 1a1 is clamped by the rotary interference force of the working end of the rotary unscrewing mechanism 5. The outside of unit drawer 1a has a cover panel, and the area of the cover panel is larger than the section of unit drawer 1a, so the bottom of the cover panel extends out of the bottom of unit drawer 1a to form a limit step 1a 2.
The supporting mechanism 6 is inserted into the bottom of the unit drawer 1a to support the unit drawer 1a, and the positioning driving mechanism 7 is used for converting the horizontal pushing force of the unit drawer 1a into the horizontal pushing force of the supporting mechanism 6.
In the present invention, as shown in fig. 4, the rotary unscrewing mechanism 5 includes a rotary motor 5a, a rotary seat 5b and a chuck 5c, the rotary motor 5a is fixedly installed on the pushing seat of the lateral pulling mechanism 4, the rotary seat 5b is fixedly installed on the output end of the rotary motor 5a, the chuck 5c is fixedly installed on the rotary seat 5b, a gap for inserting the knob 1a1 is left between the chucks 5c, and an anti-slip pad is disposed inside the chuck 5 c. After horizontal pulling mechanism 4 promoted chuck 5c card outside at knob 1a1, the controller will control rotating electrical machines 5a to work for rotating electrical machines 5a drives roating seat 5b and rotates, makes roating seat 5b drive chuck 5c and rotates, and then opens knob 1a1, opens the back, because the conflict frictional force between slipmat and knob 1a1, when horizontal pulling mechanism 4 withdraws, chuck 5c can pull unit drawer 1a and take out from the cabinet body 1. Wherein, the rotation of the knob 1a1 realizes the opening and locking structure of the unit drawer 1a and the cabinet 1, which belongs to the prior art. Furthermore, since the knob 1a1 usually has a resilient detent to lock it in either the open or closed position, the knob 1a1 has some damping during the initial phase of operation of the knob 1a1 and is usually restrained from further rotation by a limit when the knob 1a1 is rotated to the open position. Therefore, when the knob 1a1 is rotated to an open or closed state by the clip 5c, under the action of the elastic positioning device or the limit, a certain elastic torque is provided between the knob 1a1 and the clip 5c, and the elastic torque enables a certain pulling driving force to be provided between the anti-slip pad inside the knob 1a1 and the knob 1a1, thereby ensuring that the unit drawer 1a can be pulled out from the cabinet 1. The unit drawer 1a is connected to the cabinet 1 through a sliding rail, so that the driving force required for pulling out the unit drawer 1 is not large, and the unit drawer 1a can be pulled out through friction force in this embodiment, and therefore other forms of hanging modes are not described in this embodiment again. In addition, the chuck 5c and the knob 1a1 can be designed to be a matched and specially-structured form-locking connection, so that the chuck 5c can be hooked on the knob 1a1 after rotating for a certain angle, but the design is preferably designed to realize the hooking or the disengagement through the relative rotation between the chuck 5c and the knob 1a 1. Of course, the chuck 5c may be a clamping cylinder.
In the above process, the knob 1a1 is turned by turning the unscrewing mechanism 5, and the first effect is that the knob 1a1 can be turned, so that the unit drawer 1a is separated from the cabinet 1, and the circuit between the unit drawer 1a and the cabinet 1 is broken (also belonging to the prior art). Secondly, friction force exists between the rotary unscrewing mechanism 5 and the unit drawer 1a, so that the unit drawer 1a is abutted and clamped, and preparation is made for subsequent pulling out.
