The present invention relates to a positioning device used on a rack, and more particularly, to a positioning device for more securely position equipment unit on the rack.
BACKGROUND OF THE INVENTIONGenerally, there are multiple equipment units such as servos, cased computers and electronic appliances connected to a rack so as to save space. In order to allow each of the equipment units to be pulled from the rack for convenience of maintenance, each equipment unit is cooperated with two slide assemblies or support frames on two sides thereof so that the equipment units can be retracted in the rack and positioned by the slide assemblies or support frames.
The conventional way for positioning the equipment units is to use lugs on the front board and the lugs have holes or bolts to connect the rack to prevent the equipment units from dropping out from the rack.
However, some of the equipment units are heavy so that when they are transported, the lugs on the front board connected between the rack and the front end of the servo is not strong and secure. Similarly, the racks cannot bear vibration when in use.
SUMMARY OF THE INVENTIONThe present invention intends to provide a positioning device used on a rack which securely connects the equipment unit to the rack in a frequent vibration environment.
The present invention relates to a positioning device which comprises a first board having a first positioning portion extending therefrom and a first hole is defined through the first positioning portion. A second board is located corresponding to the first board and has a second positioning portion which is located corresponding to the first positioning portion. The second positioning portion is bent from the second board and has a second hole. A connection portion is connected to the first and second boards. A hook extends from one of the first board, the second board and the connection portion.
Preferably, the first positioning portion is substantially perpendicular to the first board and the second positioning portion is substantially perpendicular to the second board.
Preferably, the first board has an extension portion extending from a top thereof.
Preferably, the extension portion is substantially perpendicular to the first board.
Preferably, the hook is a U-shaped hook.
Preferably, the hook extends from a conjunction of the first board, the second board and the connection portion.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The second positioning portion 24 is connected to the threaded hole 42 of the support frame 32 by a second bolt 50 inserting through the second hole 26 of the second positioning portion 24. By the engagement of the hook 18 of the positioning device 10 and the side wall 44 of the equipment unit 28, the equipment unit 28 is prevented from shaking.
The equipment unit 28 is securely connected to the rack by the positioning device 10 and ensured to be firmly secured in the rack during a frequent vibration environment.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
