A three-position positioning interlocking mechanism traction locking plate anti-misoperation force-increasing mechanism assembly comprises the three-position positioning interlocking mechanism traction locking plate anti-misoperation force-increasing mechanism, a position positioning piece 14 and a groove-shaped positioning piece 16, wherein the position positioning piece 14 and the groove-shaped positioning piece 16 are installed on a unit chamber layer plate, and when the three-position positioning interlocking mechanism traction locking plate anti-misoperation force-increasing mechanism moves from a separation position to a test position along with a drawer 22 and is positioned, a spiral force-increasing propelling mechanism starts to enter a matching state with the groove-shaped positioning piece 16.
The three-position positioning interlocking mechanism pulls the locking plate to prevent misoperation of the boosting mechanism and the assembly thereof, and automatically positions the drawer 22 and the locking spiral boosting mechanism when the assembly is in a locking state. The drawer 22 can only be moved into position by the unlocking position positioning interlocking mechanism, and after the drawer is moved into position, the position positioning interlocking mechanism is automatically positioned, and the spiral boosting mechanism is automatically locked. If the switch is switched on, the switching-on interlocking connecting rod enters the switching-on interlocking hole 1-1, the position positioning interlocking mechanism cannot be unlocked when the position positioning interlocking mechanism is locked, the drawer 22 cannot move, and the spiral boosting propulsion mechanism is completely locked by the traction locking plate 12 and cannot be operated by hand. The structural strength of the spiral reinforcement propelling mechanism locked by the traction locking plate 12 exceeds the strength of a hand tool, so that the hand tool is operated by dead force even if the hand tool is manually operated by mistake, the hand tool is broken, and the interlocking propelling mechanism and the assembly thereof cannot be damaged.
A drawer unit comprises a unit chamber, a drawer 22 in the unit chamber and the three-position positioning interlocking mechanism traction locking plate anti-misoperation force-increasing mechanism assembly, wherein the three-position positioning interlocking mechanism traction locking plate anti-misoperation force-increasing mechanism assembly is arranged in the drawer 22, and a position positioning piece 14 and a groove-shaped positioning piece 16 are arranged on a unit chamber layer plate. When the drawer 22 is moved from the disengaged position to the testing position and is positioned in the testing position by the position-setting interlock, the screw drive mechanism is brought into engagement with the slot-shaped positioning element 16.
The drawer panel 31 is provided with an unlocking button 20, the unlocking button 20 applies unlocking operation force to the position positioning interlocking mechanism, the position positioning piece 14 is provided with a positioning notch matched with the position positioning mechanism to position the drawer 22, the groove-shaped positioning piece 16 is provided with at least two front and back arranged inclined grooves matched with the spiral boosting mechanism, and the unlocking button 20 is provided with a padlock hole 20-1.
Between the disconnected position and the testing position, the drawer 22 is moved in a hand-pull or hand-push operation, while between the testing position and the connecting position, the drawer 22 is moved in a hand-push operation because: the screw-boost propulsion mechanism is the most efficient propulsion means by having only a slight resistance to the auxiliary plug to move the drawer 22 between the disengaged position to the testing position, and by having a resistance to the spring pressure of the main circuit plug to move the drawer 22 between the testing position to the engaged position, particularly at current levels of 630A, 800A.
The three-position positioning interlocking mechanism pulls the locking plate to prevent misoperation and force increasing mechanism is unlocked by the unlocking button 20 to remove the position positioning of the drawer 22, in the moving process of the drawer 22, the position positioning sliding shaft 5 moves out of the positioning notch of the position positioning piece 14 and moves along the outer side of the position positioning piece 14, as long as the drawer 22 enters a set position, under the pressure action of the position locking plate reset spring 4, the position positioning sliding shaft 5 automatically enters the positioning notch of the position positioning piece 14 to position the position of the drawer 22, and the position indication sliding shaft 8 synchronously moves in the position indication positioning piece 15 to accurately indicate the position.
The closing interlocking stop opening 2-3 is specifically positioned at the plate end of the position locking plate 2, and a closing interlocking guide hole 17-1 is formed in the interlocking mechanism cover plate 17. When the switch is switched on, the switching-on interlocking rod 21 penetrates through the switching-on interlocking guide hole 17-1, the switching-on interlocking stop opening 2-3 is inserted into the switching-on interlocking hole 1-1, the position locking plate 2 is locked at the same time, and the position positioning interlocking mechanism and the spiral boosting propulsion mechanism cannot be operated any more.
When the unlocking button 20 is pressed, the traction lock plate 12 acts to unlock the screw boosting mechanism, and the drawer 22 is moved between the separated position and the test position by hand pulling or pushing, because the screw boosting mechanism does not yet start to enter the matching state with the groove-shaped positioning piece 16 between the separated position and the test position, even if the unlocking screw boosting mechanism is unlocked, the screw boosting mechanism only idles when a hand tool is inserted. Only in the test position, the screw boosting propulsion mechanism starts to be matched with the groove-shaped positioning piece 16, and the drawer 22 can be manually operated to move only by inserting a hand tool.
The unlocking button 20 is locked through the padlock hole 20-1, and when maintenance is guaranteed, three positions can be used for locking.
The working principle of the drawer unit of the present embodiment is as follows:
when drawer 22 is in the disengaged position, the position indicating mechanism indicates "disengaged" via the position indicator, and drawer 22 is pushed from the disengaged position to the testing position.
When the hand-pushed drawer 22 reaches the test position, the position fixing slide shaft 5 automatically enters the test position fixing notch of the position fixing member 14 under the pressure of the position locking plate return spring 4 to fix the position of the drawer 22. Simultaneously, the position indicating slide shaft 8 is urged by the position positioning member 14 against the spring pressure of the position indicating return spring 9 to bring the "test" indicator of the position indicator 11 into a corresponding position in the position indicating window 23 of the drawer panel 31. Meanwhile, the traction locking plate 12 is reset and translated to lock the spiral boosting propulsion mechanism, so that the spiral boosting propulsion mechanism is in a non-shakable state.
the unlocking button 20 is pressed to unlock the drawer 22 and the spiral boosting mechanism, a hand tool is inserted into the spiral boosting mechanism, the hand-operated drawer 22 moves to the connecting position, the unlocking button 20 is released after the hand-operated drawer 22 passes through the test position, and the unlocking button 20 resets under the action of a spring of the unlocking button 20. The process of pressing the unlock button 20 to unlock the drawer 22 and the screw boosting propulsion mechanism is: the unlocking button 20 is extruded with the head end of the operating arm 2-1 in the process of pushing into the drawer 22, the unlocking operating force of the unlocking button 20 is transmitted to the position locking plate through the operating arm, the position locking plate 2 swings, the position positioning sliding shaft 5 on the position locking plate is separated from the test position positioning notch of the position positioning piece, and the drawer 22 is unlocked; meanwhile, the locking plate traction head 2-2 inserted into the driving notch drives the traction locking plate 12 to translate, and the traction locking plate is separated from the position locking hole in the side face of the operating shaft sleeve 13-2, so that the spiral boosting propulsion mechanism is unlocked and is in a shakable state.
When the drawer 22 is manually operated by hand to enter the connection position, the position-fixing slide shaft 5 automatically enters the connection position-fixing notch of the position fixing member 14 under the pressure of the position-locking plate return spring 4, and the "trial" indication symbol of the position indication plate 11 enters the corresponding position of the position indication window 23 of the drawer panel 31. Meanwhile, the traction locking plate 12 is reset and translated to lock the spiral boosting propulsion mechanism.
When the drawer 22 is at the connection position, the main switch can be switched on, the switching-on lock rod is directly inserted to the lower part of the unit chamber layer plate and is extruded with the switching-on interlocking blocking opening 2-3, and the position locking plate 2 is in a complete locking state and cannot be unlocked. The spiral boosting propulsion mechanism is in a complete locking state, the unit door cannot be opened, and the operation of the drawer can be recovered only by the opening main switch.
Example 2: on the basis of the embodiment 1, the traction locking plate 12 and the spiral boosting mechanism are cancelled, and the interlocking mechanism of the embodiment 2 can meet the technical requirements of the application function standard of the drawer 22 in three positions of hand pulling propulsion and hand pulling extraction. But only applied to the drawers 22 with current levels of 125A, 250A and 63A, and in the current level drawers 22, the plug pressure of the main and auxiliary circuit plugs is not more than 900N, which relatively meets the requirement of manual operation.
However, the drawer unit structure and the current class specification have various types, only the manual pulling and pushing and manual pulling operation mode of the embodiment 2 cannot meet the pushing operation of the large-current class drawer 22, the spiral boosting mechanism and the three-position positioning interlocking mechanism of the embodiment 1 of the traction locking plate need to be added to prevent the misoperation of the boosting mechanism of the traction locking plate, the position is clear, and the requirements of labor saving, rapidness, stability, reliable operation and convenient operation can be met.
