Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings:
as shown in the figure, the tripping, resetting and pushing interlocking mechanism of the draw-out switch cabinet comprises a mounting bracket 1, a pushing mechanism 2 and an operating mechanism, wherein the operating mechanism comprises a swing arm 3, a locking plate 4 and a resetting elastic piece.
The mounting bracket 1 is formed by fastening and connecting a plurality of brackets such as a front bracket, a middle bracket, a rear bracket and a side bracket together through bolts, and is convenient for product assembly.
The pushing mechanism 2 is installed on the installation support 1, and generally comprises a transmission screw rod installed on the rear side of the installation support 1 and a positioning piece installed on the cabinet body and adapted to the transmission screw rod to push the drawer to move back and forth, and the drawer is moved in the cabinet body by driving the transmission screw rod to rotate and matching with the positioning piece, so that the action is stable and reliable.
Swing arm 3 includes connecting axle 33 of pivot 31, linking arm 32 one end, be equipped with the mounting hole 11 with 31 adaptations of pivot on the installing support 1, pivot 31 passes and installs on installing support 1 through the snap ring behind the mounting hole 11 to can follow 11 spin motions of mounting hole, pivot 31 center is equipped with square hole 34, can be connected with the operating handle on the drawer through square hole 34, thereby it is rotatory to drive swing arm 3 through operating handle.
The locking plate 4 is wholly "L" type structure including horizontal section and vertical section, just locking plate 4 slides along the horizontal direction and sets up on installing support 1, the upper end of the vertical section of locking plate 4 is equipped with the U type groove 41 that corresponds the adaptation with connecting axle 33, the horizontal section of locking plate 4 is established in advancing mechanism 2 top, and its tip can constitute the linkage with the interior mechanism of operating of pull-out cubical switchboard and be connected. The internal operation mechanism (not shown in the figure) is the prior art, and the locking plate 4 can drive the switch-on and switch-off of the circuit breaker in the switch cabinet through the internal operation mechanism.
The elastic component that resets is torsional spring 5, 31 lateral walls of pivot are equipped with draw-in groove 35, 5 covers of torsional spring are established outside pivot 31, and its one end inserts draw-in groove 35 and is connected with pivot 31, and the other end is buckled and is the annular, fixes on installing support 1 through the screw.
During closing, the operating handle is rotated, the operating handle overcomes the elastic force of the torsion spring 5 to drive the swing arm 3 to rotate, the swing arm 3 rotates to stir the locking plate 4 to transversely slide, and the locking plate 4 drives the circuit breaker to realize closing through the internal operating mechanism and is kept at the closing position.
When faults such as short circuit, overload, electric leakage and the like occur, the circuit breaker in the switch cabinet automatically trips and is opened, the opening action of the circuit breaker drives the locking plate 4 to transversely slide and reset through the internal operating mechanism, meanwhile, due to the fact that the closing locking of the circuit breaker is lost, the torsion spring 5 can also rapidly reset and drive the swing arm 3 to rotate and reset, the reset rotation of the swing arm 3 can drive the locking plate 4 to transversely slide and reset, and the reset rotation of the operating handle is realized.
Set up the elastic component that resets on swing arm 3, when the tripping operation of circuit breaker dropout in the pull-out type cubical switchboard, the swing arm can reset rapidly under the effect of elastic component that resets, with circuit breaker cooperation drive in the mechanism of operating, operating device, operating handle realizes resetting, not only can further improve the dropout effect, and can drive operating handle resets, can obviously see out switch tripping operation back operating handle position change directly perceivedly, play the indicative function, played better effect to the power consumption safety.
Wherein, the elastic component that resets is not restricted to the torsional spring, but when adopting the torsional spring, can also set up a plurality of location regulation holes 12 of arranging along 11 center circumference of mounting hole on the installing support 1, torsional spring 5 is through being connected with different location regulation holes 12, can realize the regulation of elasticity that resets, can adjust the elastic force that resets according to actual requirement, and the practicality is better, and application range is wider.
In addition, operating device still includes interlocking lever 6, interlocking lever 6 slides along vertical direction and sets up on installing support 1, and its lower extreme and advancing mechanism 2 are corresponding, interlocking lever 6 is connected with the linkage of locking plate 4, interlocking lever 6 has the first position of closing a floodgate with advancing mechanism 2 locking to and the second position of separating the unblock with advancing mechanism 2 during the separating brake, the locking function when guaranteeing to close a floodgate, avoids advancing mechanism 2's maloperation, further plays the safety action.
Wherein, be formed with guide way 42 on the horizontal segment of locking plate 4, the metallic channel 42 misplaces and is in the not horizontal segment of co-altitude around including two, and two horizontal segments pass through the slope section and link up from beginning to end, be equipped with location slide bar 61 on the interlocking bar 6, location slide bar 51 inserts the guide way, and when closing a floodgate, locking plate 4 lateral shifting, location slide bar 51 relative locking plate 4 move along guide way 42, thereby interlocking bar 6 slides down under the direction of guide way 42 and locks with advancing mechanism 2, and when separating brake, locking plate 4 resets, thereby interlocking bar 6 can upwards slide under the direction of guide way 42 again and separate the unblock with advancing mechanism 2.
Of course, the interlocking lever 6 can also be moved up and down in other ways, for example, the bottom edge of the transverse section of the locking plate is set to be a guide structure, the interlocking lever is provided with a spring for driving the interlocking lever to move upwards, the spring drives the interlocking lever to be attached to the bottom edge of the locking plate, so that the interlocking lever slides along the bottom edge of the locking plate, and the vertical sliding is realized under the combined action of the spring and the locking plate, but the form causes the interlocking lever and the locking plate to have large friction force and to be easily blocked.
In addition, the side of going up of the horizontal section of locking plate 4 is equipped with concave surface 43, the top that corresponds the horizontal section of locking plate 4 on installing support 1 is equipped with the location elastic component, the third position that falls into concave surface 43 when location elastic component has the combined floodgate to and break away from concave surface 43 and compress tightly the fourth position of the side on the locking plate 4 during the separating brake. Wherein, the positioning elastic piece can adopt a pressure spring.
That is to say, when closing a floodgate, the pressure spring falls into in the concave surface 43, it can not produce the resistance effect to locking plate 4, it is steady reliable to move when guaranteeing the dropout, reduce the card and hinder the problem, when reacing the separating brake position, concave surface 43 passes through the pressure spring completely, make the pressure spring just in time with the side contact of going up of the 4 horizontal sections of locking plate, thereby can provide certain resistance, ensure under the separating brake state, locking plate 4 keeps fixed, can not receive circuit breaker or other vibrating influence and the possibility of controlling about appearing, avoid appearing the swing arm after reseing, its connecting axle is deviate from behind the U type groove because of the locking bar removes the problem that can't normally playback, further ensure its stable in structure reliable.
