Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
Structure of the present invention as shown in Figures 1 to 5, be a kind of switchgear drawer fall-proofing device, described switchgear drawer comprises drawer side 8, and the top of described switchgear drawer is upper strata drawer tray 12.The present invention is applicable to the occasion that drawer in low-voltage switch cabinet of drawer needs to take to prevent from falling measure.
In order to solve prior art Problems existing and overcome its defect, realize making that the fall prevention structure of drawer is safer, the goal of the invention of more convenient operation, the technical scheme that the present invention takes is:
As shown in Figure 1 to Figure 3, switchgear drawer fall-proofing device of the present invention, the side of described drawer side 8 arranges vertical anti-drop rod 1, and described fall-proofing device 13 arranges the driving mechanism driving anti-drop rod 1 to move up and down.
In FIG, drawer status is that drawer advances initial condition, and modified node method is made up of upper strata drawer tray 12, carry hand bit manipulation fall-proofing device 13, drawer side 8.
In figs. 2 and 3, this carry hand bit manipulation fall-proofing device is made up of anti-drop rod 1, anti-drop rod guide finger 2, driving lever rotating shaft 3, driving lever 4, torsion spring 5, packing ring 6, carry hand passing hole 7, drawer side 8.
Specific as follows:
Described drawer side 8 be fixedly installed two anti-drop rod guide fingers 2 and arrange up and down, described anti-drop rod 1 is slidably matched by the anti-drop rod gathering sill of two on it 9 and these two anti-drop rod guide fingers 2.
Anti-drop rod guide finger 2 adopts the mode of riveted joint to be arranged on drawer side 8, and its end is provided with the structure preventing anti-drop rod 1 from deviating from from its axle.
Described fall-proofing device is provided with driving lever 4; The middle part of described driving lever 4 is arranged on described drawer side 8 by driving lever rotating shaft 3; Described anti-drop rod 1 is arranged the driving lever groove sliding pin 14 be fixedly connected with it, described driving lever groove sliding pin 14 is slidably matched with the driving lever gathering sill 15 on described driving lever 4 one end.
Driving lever rotating shaft 3 is fixedly connected on drawer side 8, and its end is provided with the structure preventing driving lever 4 from deviating from from its axle.
Driving lever 4 is provided with driving lever gathering sill 15, driving lever rotating shaft 3 rotation hole, torsion spring fixing hole, driving lever 4 rotates when manual operation, drive driving lever gathering sill 15, by driving lever groove sliding pin 14 and anti-drop rod 1 routing motion, realize controlling anti-drop rod 1 and to move up and down and spacing.
Described drawer side 8 arranges carry hand handle hole 7, and the other end of described driving lever 4 is in carry hand handle hole 7 position.When manual operation is tall and erect, holds carry hand handle hole 7 from top, meanwhile, this one end of driving lever 4 is moved upward, overcomes the torsion of torsion spring 5, realize anti-drop rod 1 and move downward, can drawer be extracted out.
Described anti-drop rod 1 end upwards, towards in cabinet for guiding hypotenuse 10, towards outside cabinet while be vertical position-limited edge 11.
In figs. 2 and 3, anti-drop rod 1 is provided with anti-drop rod gathering sill 9, guiding hypotenuse 10, position-limited edge 11, anti-drop rod gathering sill 9 coordinates with anti-drop rod guide finger 2, realizes anti-drop rod 1 vertical up-or-down movement and spacing.
Described driving lever rotating shaft 5 is set with torsion spring 5, between described torsion spring 5 and drawer side 8, is provided with packing ring 6; The torsion direction of described torsion spring 5 is that anti-drop rod 1 is moved upward.
One end gib head of torsion spring 5, blocks driving lever 4; One end gib head of torsion spring 5, is fixed on drawer side 8.
Torsion spring 5 is fixed by torsion spring fixing hole on packing ring 7, driving lever rotating shaft 3, driving lever 4 and drawer side 8, provides spring force to driving lever 4, pushes up anti-drop rod 1 to extreme higher position all the time, the service position that namely drawer is dropproof.
The present invention falls for preventing drawer in low-voltage switch cabinet of drawer, designs above-described drawer carry hand bit manipulation fall-proofing device.In drawer assembling process, the riveted joint of this device is assembled in drawer left side plate on carry hand through hole 7 position.Utilize the anti-drop rod 1 on fall-proofing device to coordinate with the structural flange of upper strata drawer tray 12, prevent from falling when drawer is outwards extracted out in low-voltage switch cabinet of drawer.When drawer is extracted out, need to catch carry hand through hole with hand is firm, provide a kind of handling safety reliable, anti-misoperation, structure is simple, drawer fall-proofing device reasonable in design.
As shown in Figure 4: after adopting above-mentioned structure, when drawer advances, the guiding hypotenuse 10 in anti-drop rod 1 contacts with the structural flange of upper tray, presses anti-drop rod 1 and drives driving lever 4, and compressing torsion spring 5, drawer enters smoothly.After drawer enters, torsion spring 5 discharges elastic force, drives driving lever 4, anti-drop rod 1 is promoted to initial position and service position.As without manual operation, drawer can not be deviate from.
As shown in Figure 5: when drawer is extracted out, the position-limited edge 11 in anti-drop rod 1 contacts with the structural flange of upper tray, prevents drawer from extracting out, plays dropproof effect.Now only need operating personnel with the hands to catch left side plate carry hand through hole 7, stir both sides driving lever 4 with finger, drive anti-drop rod 1 to fall, now operating personnel's both hands are firm catches left side plate carry hand 7, drawer can be extracted out safely.The problem fallen can not be produced.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
