Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in FIG. 1 to 3: the drawer position device of described low-tension switch cabinet comprises support 1, slide block 2, display pole 3, pin plate 4, back-moving spring 5, propelling spring 6, hold-down screw 7, packing ring 8, ball 9, hold-down nut 10, drawer locating piece 11, isolation sensor 12, test sensor 13, working sensor 14, dust panel 15, sensor bezel 16, drawer 17, locking position button 18, position display window 19, mounting panel 20, alignment pin 21, chute 31, location hole 32, location groove 33, location notch 34, skewed slot 35, jump-ring slot 36, hook hole 37, hook axle 38, oblique sliding surface 39, pin plate jack 40, guide rail 41, pin plate location notch 42, skewback 43 etc.
As shown in Figure 1, the present invention includes and be arranged on low tension switch dust panel 15 cashier's office in a shop, at the bottom mounting guide rail 41 of dust panel 15, guide rail 41 is installed drawer 17, drawer 17 can insert along guide rail 41 or extract out, in the inner side of drawer 17, propulsive mechanism is installed, at arranged outside locking position button 18 and the position display window 19 of drawer 17;
As shown in Figure 2 and Figure 3, described propulsive mechanism comprises support 1 and slide block 2, mounting plate 20 on support 1, at the sidepiece setting position groove 33 of mounting panel 20, in slide block 2 insertion position groove 33, one end of slide block 2 contacts with locking position button 18, and the sidepiece of slide block 2 arranges skewed slot 35; Described mounting panel 20 is provided with vertical chute 31, pin plate jack 40 is set on the top of mounting panel 20, in pin plate jack 40, insert pin plate 4; In the skewed slot 35 of described slide block 2 and the chute 31 of mounting panel 20, arrange hold-down screw 7, hold-down screw 7 penetrates in packing ring 8 and ball 9, and is connected with pin plate 4, fastening by hold-down nut 10; Thus when slide block 2 carries out movable, drive ball 9 to move along the chute 31 of support 1, thus pin plate 4 is driven to move up and down; As shown in Figure 1, in the bottom of described dust panel 15, drawer locating piece 11 is set, drawer locating piece 11 is provided with three pin plate location notchs 42, three pin plate location notchs 42 are respectively the location hole that drawer 17 is in isolation, test, work three positions, and pin plate 4 inserts in pin plate location notch 42 positioning action played drawer 17; When pin plate 4 is moved up by ball 9 drive, by when shifting out in pin plate location notch 42, drawer 17 is free to insert or extract out;
As shown in Figure 1 and Figure 2, arrange jump-ring slot 36 at the sidepiece of described slide block 2, in jump-ring slot 36, install propelling spring 6, the two ends of propelling spring 6 withstand slide block 2 and mounting panel 20 respectively; Slide block 2 can rebound by propelling spring 6, and now, ball 9 is along chute 31 slide downward, and drive pin plate 4 to move down, then pin plate 4 falls into pin plate location notch 42;
As shown in FIG. 1 to 3, be provided with location notch 34 in the end of described support 1, display pole 3 is set in location notch 34; One end of described display pole 3 is position display region, and this position display region is positioned at the rear of the position display window 19 of drawer 17, can observe the position shown by display pole 3 by position display window 19; The other end of described display pole 3 is provided with alignment pin 21, and alignment pin 21 is arranged in the location hole 32 on mounting panel 20; Connect back-moving spring 5 between described display pole 3 and support 1, one end of back-moving spring 5 hangs in the hook hole 37 on display pole 3, and the other end of back-moving spring 5 hangs on the hook axle 38 of support 1; Be provided with oblique sliding surface 39 in the bottom of described display pole 3, this oblique sliding surface 39 contacts with the skewback 43 being arranged on drawer locating piece 11 side, and tiltedly sliding surface 39 matches with the inclined-plane of skewback 43, realizes rising or the decline of display pole 3; When drawer 17 is positioned at different positions, the oblique sliding surface 39 of display pole 3 contacts with the diverse location of skewback 43, and display pole 3 is in different positions, can observe the position that now drawer 17 is in from position display window 19;
As shown in Figure 1, the dust panel 15 of described drawer locating piece 11 side installs isolation sensor 12, test sensor 13 and working sensor 14, and isolation sensor 12, test sensor 13 and working sensor 14 are corresponding with the position of the isolation of drawer locating piece 11, test, work respectively; At the sidepiece sensor installation baffle plate 16 of described drawer 17, when drawer 17 lays respectively at isolation, test, service position, sensor bezel 16 shelters from isolation sensor 12, test sensor 13, working sensor 14 respectively, thus sends the position of drawer to remote terminal.
The course of work of the present invention: first arrive isolated location when drawer 17 enters, now, the sensor bezel 16 of drawer 17 sidepiece covers isolation sensor 12, thus the relevant position of display drawer 17;
Press locking position button 18, contacted with slide block 2 by locking position button 18, and promote slide block 2 and push ahead, drive ball 9 to move up along chute 31, and drive pin plate 4 to move up, thus pin plate 4 leaves pin plate location notch 42, drawer 17 realizes moving forward, and arrives test position; Disengaged position locking press button 18, slide block 2 moves backward under the effect of propelling spring 6 bounce, drives ball 9 to move down along chute 31, and drives pin plate 4 to move down to be inserted in pin plate location notch 42, to fix the position of drawer 17; Now, the sensor bezel 16 of drawer 17 sidepiece blocks test sensor 13, thus display drawer 17 is positioned at experimental site;
When drawer 17 needs to push ahead, press locking position button 18 again, promote slide block 2 by locking position button 18 and move, drive ball 9 to move up along chute 31, and drive pin plate 4 to move up, pin plate 4 leaves pin plate location notch 42, drawer 17 realizes moving forward, and arrives service position; Disengaged position locking press button 18, slide block 2 moves backward under the effect of propelling spring 6 bounce, drives ball 9 to move down along chute 31, and drives pin plate 4 to move down to be inserted in pin plate location notch 42; Now, the sensor bezel 16 of drawer 17 sidepiece blocks working sensor 14, thus display drawer 17 is positioned at service position;
When drawer 17 shifts out, as long as pin locking position button 18, promote slide block 2 by locking position button 18 to move, ball 9 is driven to move up along chute 31, and driving pin plate 4 to move up, pin plate 4 leaves pin plate location notch 42, and drawer 17 moves backward, successively through test position, isolated location, until drawer 17 is extracted out outside low voltage switchgear.
In the process that drawer 17 inserts or extracts out, oblique sliding surface bottom display pole 3 and the contact of incline plane of skewback 43, and according to the diverse location of drawer 17, display pole 3 is in the differing heights rising and decline, the diverse location that display pole 3 shows can be observed, i.e. the diverse location that is in of drawer 17 from position display window 19.
