Abstract

The utility model discloses an automatic support server tray. The utility model is provided with a tray body (1) which is provided with at least one bracket, one end of the bracket is hinged with the tray body (1), and the other end of the bracket is provided with a roller. The tray is provided with the foldable bracket, when the tray carries a server and is extracted from the inside of a cabinet by a definite distance, the bracket can fall automatically and keep the center of gravity of the cabinet stable; the situation that the cabinet falls because the center of gravity of the cabinet is deflected when the tray which carries the server which is too heavy is extracted can not occur, and the situation that the tray is pressed and damaged by the heavy server because the tray is extracted by a too long distance. Besides, when the tray is retracted to the cabinet, the tray can be automatically folded; the utility model has the advantages of simple structure and easy use.

Description

Automatic supporting device pallet

Technical field:

The utility model relates to a kind of annex of rack, is a kind of automatic supporting device pallet.

Background technology:

At present, people are convenient for the maintenance service device, often server is placed in can be as drawer relative rack slide on the pallet of extracting out.And the pallet weight capacity of existing rack is relatively poor, and when the heavier server of pallet carrying was extracted rack out, easy serviced device compression failure also easily made rack lose center of gravity and topples over.People extract rack cabinet on opportunity out and strike the beam in order to prevent server, be everlasting rack bottom be provided with anchor bolt with rack with ground is fixed or the stabilizing member increase cabinet base area that lands is installed in the rack bottom, but, be equipped with in the machine room of antistatic floor and can't use anchor bolt to fix, exist and take the machine space and influence the interior defective attractive in appearance of machine room and install stabilizing member additional.And above-mentioned two kinds of methods still can't solve the heavier server of pallet carrying when extracting rack out, easily by the problem of compression failure.

Summary of the invention:

The purpose of this utility model is, a kind of automatic supporting device pallet is provided, it need not to establish anchor bolt or install stabilizing member additional in the rack bottom, can solve when heavier server is extracted out by pallet, rack easily strike the beam or pallet by the compression failure problem, can increase the weight capacity of pallet effectively, the service of guaranteeing 150 kilograms of pallet carryings when extracting 100 centimetres out in the rack, do not take place that rack strikes the beam or pallet by the accident of compression failure.

The purpose of this utility model is achieved through the following technical solutions: automatic supporting device pallet, and it has tray body, and a support is installed on the tray body at least, and an end of support and tray body are hinged, and the other end is installed roller.

For further realizing the purpose of this utility model, can also adopt following two kinds of technical schemes to realize: first support is installed on the tray body, first roller is installed on first support, one end of first support and first pull bar is hinged, one end of the other end of first pull bar and first rocking arm is hinged, and first rocking arm and tray body are hinged.First rocking arm is provided with first projection, and the angle of the axis of the axis of first projection and first rocking arm is less than 180 degree.First runner is installed on first projection.The axle that first support and first pull bar are hinged is gone up first spring is installed, and an end of first spring is connected with first pull bar, and the other end of first spring is connected with first support.Second support is installed on the tray body, second roller is installed on second support, an end of second support and second pull bar is hinged, and the other end of second pull bar and second rocking arm, one end are hinged, and an other end of second rocking arm and tray body are hinged.Second rocking arm is provided with second projection, and the angle between the axis of second projection and second rocking arm is less than 180 degree.First runner is installed on first projection, second runner is installed on second projection.The axle that first support and first pull bar are hinged is gone up first spring is installed, and an end of first spring is connected with first pull bar, and the other end of first spring is connected with first support; The axle that second support and second pull bar are hinged is gone up second spring is installed, and an end of second spring is connected with second pull bar, and the other end of second spring is connected with second support.Installing connecting rods between second support and second support.

The good effect of generation of the present utility model is: on its pallet bracket with foldable is housed, when pallet carries server when extracting certain distance out in by rack, support can fall automatically, and remain the rack steadily of centre of gravity, neither can occur because pallet carries heavier server when extracting rack out, the situation that pallet is extracted the heavier server compression failure of the long quilt of rack distance out can not appear in the situation that makes rack centre-of gravity shift cause rack to topple over yet.And when pallet was regained rack, pallet can be packed up automatically, has advantage simple in structure, easy to use.
