Description
Technical field
The invention belongs to technical field of electronic products, and in particular to a kind of labour-saving movable type server.
Background technique
With the development of information technology, kownledge economy is in explosive growth, is operation and the needs for storing data, all kinds of numbers
It also emerges one after another according to the server of storage and operation.
Server is to make it for combining installation panel, plug-in unit, subrack, electronic component, device and machine components and component
Constitute the installs case of an entirety.Server cabinet is made of frame and cover board, is generally had the shape of a rectangular parallelepiped, and landing is put
It sets.It provides adaptable environment and security protection for electronic equipment normal work.This is to be only second to system-level level-one assembling.
The cabinet of server has good technical performance.The structure of cabinet should have good stiffness and strength and good electromagnetism
The performances such as isolation, ground connection, noise isolation, ventilation and heat.In addition, server cabinet should have anti-vibration, shock resistance, it is corrosion-resistant,
The performances such as dust-proof, waterproof, radiation protection, to guarantee that equipment reliablely and stablely works.
Since the general sufficiently bulky and weight of server is very big, rolled for easy to carry would generally be installed in server bottom
Wheel, only needs Level Promoting that can move, however, there is also need to consolidate idler wheel after reaching predetermined position using idler wheel
Fixed problem, idler wheel fixing means in the prior art are usually that idler wheel is carried out clamping, limit the trend of its rolling movement, but
Idler wheel is under the driving of certain force or horizontal sliding may occur, and for being connected with various power supply lines and data line
For server, occurs to shake and not allow situations such as mobile.
The patent of patent No. CN 206923172U discloses a kind of big data server, has used rotatable support rod,
The entire cabinet of server, which is propped up, keeps idler wheel hanging, to prevent idler wheel mobile, realizes and fixes, but there is following for this server
Some problems: 1. bear the weight of entire server with support rod, are easy that support rod is made to wreck, rupture, and server
It is suspended in top, easily generation safety accident, causes equipment badly damaged and casualties, there are severe compromises；2. using
Inconvenience, this structure need two personnel to operate together, first lift server side install support rod after, then lift another
Side installation, and the turn of the screw is needed in fixed support rod, it is not only time-consuming and laborious also to take manually, make to be screwed also to again
Trouble is brought when mobile.
Summary of the invention
It is an object of the invention to:
It is not fixed firmly to solve the idler wheel of mobile server in the prior art and leans on, fixed device is inconvenient to use asks
Topic, and a kind of labour-saving movable type server is provided.
The technical solution adopted by the invention is as follows:
A kind of labour-saving movable type server, including cabinet body, the cabinet body lower section are connected with universal wheel, which is characterized in that
The intracorporal bottom center of cabinet is equipped with nut, and the bottom of cabinet body offers corresponding with nut inner diameter size same position
