Abstract
A suspension device capable of preventing a low-voltage cabinet drawer from falling off comprises a hand-operated push rod, a hook, a hook groove and a drawer guide rail. The hand-operated push rod is connected to a drawer side plate, the hook groove is connected to the drawer guide rail, the hook being close to the left end of the hand-operated push rod is connected to the drawer side plate through a rotating shaft, the horizontal position of a hooked part of the hook is lower than the section of the left end of the hook groove, the hand-operated push rod is of a long-strip-shaped structure, and the two ends of the hand-operated push rod are bent by 90 degrees in the direction departing from the drawer side plate; the hand-operated push rod is a spacing structure of screws which slide along the horizontal direction; the hook groove is formed by bending a cold rolled steel plate 2.5/Q235, the bottom of the hook groove is fixed on the guide rail through a screw or welding, the upper portion of the hook groove is a 30-degree inclined plane, and the section of the right end is higher than that of the left end; and the hooked part of the hook points to the hand-operated push rod. A draw-out type low-voltage switchgear cabinet designed by the utility model is compact in structure, power distribution loops are arranged economically, the drawer unit is flexibly combined, the suspension device capable of preventing the low-voltage cabinet drawer from falling off is strong in interchangeability and maintainability, and the structure of the suspension device is general applied to power generation and power distribution fields.
Description
Technical field
The utility model relates to the suspension arrangement that a kind of anti-low voltage cabinet drawer falls.
Background technology
When low voltage cabinet drawer is outwards extracted out, need both hands to catch panel handle, drag backward, when drawer will depart from cabinet, should remove in time drawer bottom centre position, drawer is taken out of in cabinet.Sometimes both hands are not held drawer middle part timely, and while causing drawer to be extracted out, front portion surprisingly sinks and causes drawer tumble injury and personal injury.Existing drawer fall-proofing device, all the object based on prompting designs.When drawer is soon extracted out completely, drawer can be blocked by the spacing preiection on guide rail, and prompting drawer is about to extract out completely, now gently lifts drawer handle, just can continue to extract out drawer.More than design can only be played certain suggesting effect, and do not force not change hand into and remove drawer bottom centre position, in continuing outside extraction, the possibility of old tumble injury drawer still.Overcome the problems referred to above, just must design complicated drawer hitch, this will certainly increase the cost of maintenance.
Summary of the invention
The suspension arrangement that the purpose of this utility model has been to provide a kind of anti-low voltage cabinet drawer to fall, it has advantages of compact conformation, interchangeability is strong and easy to maintenance.
The utility model is achieved like this, it comprises hand push rod, hook, hook groove and drawer guideway, it is characterized in that, the hand push rod hand push rod that is connected to drawer side is connected on drawer side, hook groove is connected on drawer guideway, hook near hand push rod left end is connected on drawer side by rotating shaft, and the crotch horizontal level of hook is lower than the left end cross section of hook groove; Described hand push rod is strip structure, and two ends deviate from drawer side bending 90 degree; Described hand push rod is the screw position limiting structure sliding along horizontal direction; Described hook groove is formed by cold bundle steel plate 2.5/Q235 bending, and bottom is by screw or be weldingly fixed on guide rail, and top is the inclined-plane of 30 degree, and right-hand member cross section is higher than left end cross section; The crotch direction of described hook is pointed to hand push rod.
Technique effect of the present utility model is: the draw-out type low voltage switch cabinet compact conformation of the utility model design, and distribution loop is arranged economical, flexibly, interchangeability is strong in drawer unit combination, maintainable strong, is a kind of version that generating, distribution generally adopt.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Hand push rod 2, hook 3, drawer side 4, hook groove 5, drawer guideway in the drawings, 1.
Embodiment
As shown in Figure 1, the hitch that anti-low voltage cabinet drawer falls by being suspended on hook 2 on drawer side 3, be fixed on the hand push rod 1 on drawer side 3 and the hook groove 4 that is fixed on drawer guideway 5 forms.Hook 2 is stamped to form by cold bundle steel plate 2.5/Q235.Upper end is suspended on drawer side 3 by rotating shaft, can freely rotate around the shaft.When freedom is sagging, the clasp joint face of lower end is lower than the left part of hook groove 4.1 of hand push rod is stamped to form by cold bundle steel plate 2.0/Q235, outside bending 90 degree in two ends.By two screws, limit on drawer side 3, under external force, can move left and right, during without external force, hand push rod institute 1 is subject to frictional force can stop hook 2 to rotate.Its range being moved to the left, for making hook a little more than hook groove 4 left parts, is service position; The stroke moving right makes to link up with 2 higher than hook groove right part, is clear position.Inclined-plane hook groove 4 is formed by cold bundle steel plate 2.5/Q235 bending.Bottom is by screw or be weldingly fixed on guide rail 5, and top is the inclined-plane of 30 degree, and right part is higher than left part.
When drawer injects, hook 2 with drawer to left movement.When hook 2 touches hook groove 4, hook 2 injects and is rotated counterclockwise with drawer, crosses hook groove 4, and drives hand push rod 1 to slide on drawer side 3 to the right.When hook 2, cross after hook groove 4, hook 2 is under Gravitative Loads, and automatically sagging, it is relative with drawer side 3 static that hand push rod 1 keeps under frictional force effect, remains in clear position.After this, drawer can continue to inject.When drawer is extracted out, hook 2 moves right with drawer.When hook 2 touches hook groove 4, hook 2 is extracted out under motion effect at drawer, hooks hook groove 4, places restrictions on drawer and further extracts out.Continue to extract out drawer, only need promote hand push rod 1 left, make to link up with 2 and depart from hook groove 4.Under frictional force effect, hand push rod 1 keeps relative with drawer side 3 static, remains in service position, makes to link up with 2 and keeps disengaged position with hook groove 4, and drawer can freely be extracted out.When again inserting drawer, because hook groove 4 rear ends are higher than hook groove 4 front ends, hook 2 injects and is rotated counterclockwise with drawer under the 4 rear end effects of hook groove, drives hand push rod 1 to slide on drawer side 3 to the right.When hook 2, cross after hook groove 4, hook 2 is under Gravitative Loads, automatically sagging.Under frictional force effect, hand push rod 1 keeps relative with drawer side 3 static, remains in clear position.
