in the attached drawing, 1 is a drawer side plate, 2 is a drawer upper partition plate, 3 is a falling-proof connecting rod, 4 is a shaft sleeve, 5 is a roller, 6 is a transverse push rod, 7 is a limiting guide hole, 8 is a push rod shaft sleeve, 9 is a drawer door plate, 10 is a button, 11 is a triangular bulge, and 12 is a hook.
Detailed Description
Referring to fig. 1, the multi-link press type low-voltage power distribution cabinet drawer anti-falling device comprises an anti-falling assembly arranged on a drawer side plate 1 and a button assembly arranged on a drawer door plate 9; the anti-falling assembly comprises an anti-falling connecting rod 3 hinged to a drawer side plate, one end of the anti-falling connecting rod is provided with a hook 12 matched with a hook groove at the front end of the drawer upper partition plate 2, and the other end of the anti-falling connecting rod is matched with the button assembly. The anti-falling connecting rod is hinged with the drawer side plate and is matched with the hook groove through the hook, so that the rear end of the upper partition plate of the drawer can be effectively locked to prevent the drawer from being pulled out too much and falling when in use; the button assembly is arranged, so that a user can select whether the anti-falling assembly is required to be used or not.
The button assembly comprises a transverse push rod 6 capable of moving back and forth, one end of the transverse push rod abuts against the other end of the anti-falling connecting rod, and the other end of the transverse push rod extends out of the drawer door plate and is connected with a button 10. The transverse push rod moves back and forth by the pushing of the outer side button, and one end of the transverse push rod is contacted with the other end of the anti-falling connecting rod, so that the transverse push rod moves to drive the connecting rod to rotate, and the hook of the connecting rod is clamped into the hook groove.
One end of the transverse push rod is provided with a triangular protrusion 11, and the other end of the anti-falling connecting rod is provided with a roller 5 matched with the triangular protrusion for use. Because one end of the transverse push rod is matched with the anti-falling connecting rod through the triangular protrusion, the rotating angle of the anti-falling connecting rod is increased in the propelling process of the transverse push rod, and the hook is clamped into the hook groove more easily.
The transverse part of the transverse push rod is provided with at least two limiting guide holes 7, and the drawer side plate is provided with at least one push rod shaft sleeve 8; the push rod shaft sleeves correspond to the limiting guide holes one by one. Play the effect to the direction of horizontal push rod on the one hand through setting up spacing guide hole and push rod shaft sleeve, on the other hand still plays spacing effect around playing.
The limiting guide hole is a long round hole. The long round hole is adopted for guiding and limiting, and the effect is good.
And a shaft sleeve 4 is arranged at the hinged part in the center of the anti-falling connecting rod. The rotation is more convenient by arranging the shaft sleeve.
The transverse push rod and the button are integrally formed. The transverse push rod and the button are designed into a whole, the button is pressed to push the transverse push rod, so that the anti-falling connecting rod rotates anticlockwise, the hook at the top of the anti-falling connecting rod is separated from the partition plate at the upper part of the drawer, and the unlocking effect is achieved.
The following working principle is described:
the drawer side plate 1 is fixed by a bolt after the shaft sleeve 4 penetrates into the anti-falling connecting rod 3, and the roller 5 and the anti-falling connecting rod 3 are fixed by bolts. The transverse push rod 6 is inserted into the drawer door plate 9 and then fixed on the drawer door plate 9, and a spring is arranged in the drawer door plate 9. And the transverse push rod 6 is also connected with the limiting guide hole on the side plate of the cabinet body through a bolt, and the transverse push rod 6 is provided with a long round hole which is limited and guided through a push rod shaft sleeve.
When the drawer is drawn out to the position shown in figure 1, the hook at the top end of the anti-falling connecting rod 3 hooks the folded edge of the partition board 2 at the upper part of the drawer, so that the anti-falling effect is achieved. When the drawer needs to be drawn out, the button 10 is pressed in the direction A, at the moment, the hook at the top end of the anti-falling connecting rod 3 slides to the lower part of the partition board 2 at the upper part of the drawer, and at the moment, the drawer can be drawn out and then lifted down to the compartment.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
