Detailed Description

As shown in fig. 1, the electric cabinet closed drawer operating device comprises a control device 1, a transmission device 2 and a working device 3, wherein the control device 1 controls the movement of the transmission device 2, and the transmission device 2 drives the working device 3, so that different working modes of the working device 3 are realized.

As shown in fig. 2, the control device 1 includes a rotating assembly 11 and a control member 12. As shown in fig. 3, the rotating assembly 11 can move the control rack 14 of the transmission device 2, thereby driving the transmission device 2 to work. The control member 12 controls the rotation of the rotating assembly 11. Specifically, as shown in fig. 2 and 7, the control member 12 includes an insert having a unique contour, and the rotating assembly 11 is provided with a through hole matching with the contour of the insert, so that the control member 12 can be inserted into the rotating assembly 11, and the rotating assembly 11 is driven by the control member 12 to move through matching of the contours of the two. The insert may be a cylinder, the cylinder being a cylinder, a square cylinder or other cylinder, the maximum radial dimension of the cylinder being not greater than the minimum radial dimension of the through hole so that the cylinder may be inserted into the through hole. The column is provided with a protrusion, so that the control member 12 drives the rotating assembly 11 to rotate by using the protrusion. The protrusion can be arranged on the side surface of the column body and also can be arranged on the end surface of the column body. Preferably, as shown in fig. 4, which is a cross-sectional view of the insert, the insert is a cylinder, and the cylindrical surface of the insert is bounded by the protrusion a, and the protrusion B and the protrusion C are arranged at intervals of 90 degrees and 180 degrees, respectively. The rotating assembly 11 is a bevel gear, a through hole is formed in the rotating assembly 11, a protruding groove capable of containing the control piece 12 is formed in the through hole, and the control piece 12 can be inserted into the rotating assembly 11 only when the control piece 12 adjusts the direction of the control piece to be matched with the through hole of the rotating assembly 11. As shown in fig. 2, the control device 1 may further include an air switch assembly 13, and after the control member 12 is inserted into the rotating assembly 11, it may pass through the rotating assembly 11 and further be inserted into the air switch assembly 13. The air switch assembly 13 is provided with a recess matching the male profile of the insert, which coincides with the shape of the through hole when the rotating assembly 11 is in the end position of rotation. Wherein the recess of the air switch assembly 13 is preferably different from the through hole of the rotating assembly 11 at the initial position of rotation. The arrangement is such that when the control member 12 is in the initial state of the rotating assembly 11, the control member 12 can only drive the rotating assembly 11 to work and cannot be further inserted into the air switch assembly 13; when the control member 12 cannot further rotate the rotating assembly 11, the control member 12 can be passed out of the rotating assembly 11 and further inserted into the air switch assembly 13. When the control member 12 passes through the rotating assembly 11, the protrusion a, the protrusion B, and the protrusion C are also disengaged from the through hole of the rotating assembly 11 and enter the groove of the air switch assembly 13, so that the control member 12 drives the air switch assembly 13 without driving the rotating assembly 11. After the control member 12 drives the air switch assembly 13, because the shape of the bulge on the control member 12 is not matched with the shape of the through hole of the rotating assembly 11, the control member 12 cannot be pulled out of the control device 1 after the air switch assembly 13 works, the integrity of the function and the structure is ensured, and the operation safety is improved. Only when the control member 12 drives the air switch assembly 13 back to the initial position can the control member 12 be withdrawn from the air switch assembly 13 and back into the rotating assembly 11. It is thus ensured that the air switch assembly 13 can be actuated further only after the control member 12 has fully rotated the rotary assembly 11 into position, and conversely that the control member 12 can actuate the rotary assembly 11 again only if the air switch assembly 13 is switched off.

As shown in fig. 1, the transmission devices 2 are symmetrically arranged in the left-right direction and have the same function, and therefore, one side of the transmission devices is taken for description. As shown in fig. 5, the transmission 2 includes a control rack 14, a transmission rack 22, and a transmission gear 21. The control rack 14 and the transmission rack 22 are both meshed with the transmission gear 21, and the control rack 14 and the transmission rack 22 are not in the same plane. The transmission gear 21 is uniformly provided with teeth, so that the control rack 14 and the transmission rack 22 can be guaranteed to move along with the movement of the transmission gear 21 all the time, compared with the prior art, the gear structure is simplified, the situation that the transmission gear is provided with multiple layers of notched teeth due to the fact that racks on different layers are driven in a time-sharing mode in the prior art is avoided, and the stability of the transmission structure is improved.

And the primary plug-in rack rail 7 and the secondary plug-in rack rail 8 are respectively provided with a clamping groove. Preferably, the clamping grooves on the primary card rack rail 7 and the clamping grooves on the secondary card rack rail 8 are respectively located at two ends of the clamping channel. In order to make the sliding block 6 more easily pushed out of the clamping groove, the clamping groove can be further provided with a transition section so that the sliding block 6 can slide out of the clamping groove. The transition section of the clamping groove is arranged on one side of the clamping groove far away from the end part of the plug-in rack rail. In order to cooperate with the transition section of the locking groove, the slide 6 can be provided with a corresponding transition surface. The transition may be a ramp. The sliding block 6 is driven by a transmission rack 22, and the transmission racks 22 on the left side and the right side synchronously push the sliding block 6 to move between the primary card rack rail 7 and the secondary card rack rail 8.
