Description

Technical Field

[0001] The invention relates to an anti-dumping device, in particular to an anti-dumping device and a drawer cabinet using the anti-dumping device. Background Art

[0002] In order to load more items, most cabinets are equipped with multiple drawers. However, during use, the center of gravity of the cabinet often shifts due to the drawers being pulled out, which puts the cabinet at risk of tipping over. Therefore, most cabinets often have a fixing device added to the back of the cabinet during use, such as fixing the back of the cabinet to the wall with a drawstring.

[0003] The above fixing method is suitable for fixing the cabinet in a fixed position for a long time.

[0004] In actual use, for example, a medical cart cabinet needs to move with the position of the patient. As the number of drawers pulled out of the medical cart increases, the center of gravity of the entire vehicle body moves outward. When the center of gravity moves out of the area connecting the bottom wheels, the vehicle body is prone to tipping over under the action of a small external force.

[0005] Therefore, it is necessary to provide an anti-tipping device and an anti-tipping drawer cabinet. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, an object of the present invention is to provide an anti-dumping device and an anti-dumping drawer cabinet.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] An anti-dumping device comprises a connecting rod, a sliding block and a sliding rod;

[0009] The connecting rod is arranged longitudinally, and a plurality of sliders are fixedly arranged on the connecting rod at intervals; the slider is provided with a plurality of slideways inclined in the transverse direction; the number of sliders is greater than the number of slideways provided on a single slider;

[0010] The slide rod is matched with the slider, the end of the slide rod is placed in the slideway, the end tail is used to fix the movable part, and the movable part is linked to push the slider along the slideway to move the linkage connecting rod up and down;

[0011] The height difference between the two ends of the slideway is equal to the distance between the slideways of adjacent layers;

[0012] The bottom side of the connecting rod is provided with a tooth pattern for tooth engagement with a damping gear, and the damping gear is used for limiting the connecting rod.

[0013] The slideway is Z-shaped.

[0014] The slide bar is L-shaped.

[0015] The two ends of the slideway are open in a trumpet shape.

[0016] An anti-dumping drawer cabinet comprises a cabinet body provided with an anti-dumping device;

[0017] The connecting rod is longitudinally arranged in the cabinet through the slide rail, and the bottom of the connecting rod is gear-engaged with the damping gear fixed inside the cabinet;

[0018] The ends of the plurality of slide bars are respectively fixedly connected to the inner side surfaces of the plurality of layers of drawers.

[0019] The bottom of the cabinet is provided with rollers.

[0020] The present invention is beneficial in that:

[0021] The present invention provides an anti-tipping device and an anti-tipping drawer cabinet. The anti-tipping device uses a plurality of sliders connected in series on a connecting rod. The corresponding sliders push the connecting rod and other sliders up or down one position under the linkage of the drawers. A fixed number of slideways are arranged on the sliders to control the number of drawers that can be opened. The sliders block the slides of the other drawers, so that the drawers cannot be opened. The number of opened drawers can be used to avoid excessive displacement of the center of gravity of the cabinet, thereby preventing the cabinet from tipping over. The device has a simple structure, is practical and convenient, and has strong practicality and wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] An anti-dumping drawer cabinet is composed of a cabinet body 1 and an anti-dumping device.

[0034] Rollers are provided at the bottom of the cabinet to facilitate the movement of the cabinet to any position.

[0035] The cabinet is provided with several layers of drawers 2, such as Figure 1 As shown, this embodiment takes 6 layers of drawers as an example.

[0036] The anti-dumping device is composed of a connecting rod 3, a sliding block 5 and a sliding rod 6.

[0037] The connecting rod is arranged in the cabinet body longitudinally through the slide rail 4 (or guide seat), and the bottom side of the connecting rod is provided with teeth, which are engaged with the damping gear 7 fixed to the inner wall of the cabinet body; the damping resistance of the damping gear enables the connecting rod to stay at any height.

[0038] A plurality of slide blocks are fixedly arranged on the connecting rod, and each slide block is equipped with a slide rod. The tail end of the slide rod is fixedly connected to the inner side surface of the drawer. That is, when the drawer is pulled out, the slide rod can be pulled out.

[0039] Along the drawer pulling direction, that is, on the slider, there are several layers of slideways inclined in the transverse direction. Preferably, the slideway is Z-shaped, with trumpet-shaped openings at both ends. Preferably, the slideway is arranged on the side of the slider. Preferably, the slide bar is L-shaped, and the end is placed in the slideway. When the slide bar is moved in the transverse direction by the drawer linkage, the end of the slide bar slides in the slideway, pushing the slider up or down, and then the linkage connecting rod and other sliders thereon rise or fall.

[0040] The height difference between the two ends of the slideway is equal to the distance between the slideways of the adjacent layers. That is, when the slide bar slides from one end of the slideway to the other end, the height of the slider rising or falling is the distance between the slideways of the adjacent layers, so as to ensure that the slideway of the slider on the connecting rod is still matched with its slide bar and can slide.

[0041] The port of the trumpet-shaped slideway allows the redundant height generated after the connecting rod rises or falls to be accommodated, so as to avoid the generation of height difference, thereby preventing the end of the slide rod from entering the slideway of the corresponding slider.

[0042] The number of sliders is greater than the number of slideways provided on a single slider. Figure 2As shown, the number of sliders is 6 and the number of slideways is 3.

[0043] like Figure 7 As shown, when one of the drawers is pulled out, the connecting rod and the slider move downward together by a distance of one slide track, and at this time, the slide rods on the remaining drawers that have not been pulled out correspond to the second slide track of the slider.

[0044] like Figure 8 As shown, when a drawer is pulled out again, the connecting rod and the slider move downward together by the distance of one slide track again. At this time, a total of 2 slide track distances are moved, and the slide rods on the remaining drawers that have not been pulled out correspond to the third slide track of the slider.

[0045] like Fig. 9 As shown in the figure, when the third drawer is pulled out, the connecting rod and the slider move downwards again together by the distance of one slideway, and at this time, a total of three slideway distances are moved. The sliders on the remaining drawers that have not been pulled out correspond to the sliders, and there are no matching slideways. That is, at this time, the sliders behind the drawers that have not been pulled out are blocked by the sliders, and the drawers behind cannot be pulled out.

[0046] By limiting the number of drawers to be pulled out, the center of gravity of the entire cabinet is avoided from shifting, thereby preventing the cabinet from tipping over.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
