Abstract
The utility model provides an open device for cover of electronic equipment case. A lock pole is setted in the cover and connected with an end of a spring, the other end of which is fixed on the case. The device is characterized in that: a rack is setted on the lock pole, a gear handle is setted on the rack above, some tooth meshed with the rack are setted on the gear handle which is connected with the cover by a shaft, moreover, a handle mounted on the outer of the cover is setted on the gear handle either. The gear handle overcomes the bounce of the spring to lock or open the cover by using gear-driven lever principle, and opens the heavier cover of case door without very large force, thus, the convenience in the operating progress is improved.
Description
Technical field
The utility model relates to a kind of cabinet of electronic equipment, particularly relates to a kind of switching device of electronic equipment machine cover plate.
Background technology
The cabinet of at present common electronic equipment typically uses on the framework that screw directly is connected cabinet as the cabinet cover plate of computer, but very inconvenience of dismounting.In the nearest emerging electronic equipment chassis, cover plate one end is connected on the cabinet framework by rotating shaft, and the other end uses switching devices such as handle, latch that the cabinet cover plate is fixed on the chassis frame, this switching device mainly has handle and the inboard latch that is arranged on the cabinet cover plate outside, and latch is provided with back-moving spring.Latch is inserted at ordinary times in the snap close of chassis frame and makes cover plate be fixed on the chassis frame, when needs are opened the cabinet cover plate, by pulling the handle on the cabinet cover plate, the elastic force that overcomes back-moving spring makes latch spin off from snap close, thereby opens the cabinet cover plate.
Though but the switching device of above-mentioned this cabinet cover plate is relatively simple for structure, but for heavier cover plate or machine box door body, owing to need pulling handle directly to overcome the elastic force of spring, and this elastic force is bigger, therefore it is also bigger to need to exert oneself, and causes inconvenience in use.Because be that latch is inserted in the snap close only, fixed structure is too simple, the stationarity of cabinet cover plate is relatively poor, and the casing higher for fastening precision prescribed then is difficult to reach requirement.Simultaneously because handle is positioned at the cover plate outside and needs directly it to be applied power, so also need occupy certain space in the cover plate outside.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of switching device of electronic equipment machine cover plate, and it is in use easy and simple to handle and can improve the tightness of cabinet cover plate, saves the space that handle occupies simultaneously.
For addressing the above problem, the switching device of electronic equipment machine cover plate of the present utility model, be provided with locking bar in the cover plate inboard, this locking bar links to each other with an end of spring, and the other end of spring is fixed on the cabinet casing, it is characterized in that also being provided with on the locking bar tooth bar, above tooth bar, be provided with the gear handle, the gear handle is provided with tooth and is meshed with the tooth of tooth bar, and described gear handle links to each other with described cover plate by a rotating shaft, also is provided with the handle that is positioned at the described cover plate outside on the described gear handle.
Switching device by electronic equipment machine cover plate of the present utility model, utilize gear-driven lever principle, the elastic force that overcomes spring is with cover plate locking or unlatching, for heavier cover plate or machine box door body, do not need to get final product switch with very big power, and can guarantee the tightness when it is closed, improve the convenience in the use.
As a kind of improvement of the present utility model, described locking bar is provided with one or more latches, is provided with the snap close of equal number simultaneously on cabinet with respect to the position of latch, and described latch is inserted in the snap close under the active force of described spring.The casing higher for fastening precision prescribed then can guarantee its assembly and use requirements.
As another improvement of the present utility model, described handle is made as laminar, simultaneously the end of handle is the clasp shape.Change the rotating manner of gear into owing to the rectilinear motion mode that original hand is dialled, adopt such technical scheme the handle that occupied certain space originally also can be able to be saved, place laminar handle and only take little space, the end is the then operation of more convenient finger of clasp shape.

Embodiment
Below, in conjunction with the accompanying drawings execution mode of the present utility model is elaborated.
Schematic diagram of the present utility model as shown in Figure 1, locking bar 1 is arranged on the inboard of cabinet cover plate, and it links to each other with an end of spring 2, and the other end of spring 2 is fixed on the cabinet casing.Also be provided with tooth bar 3 on the locking bar 1, be provided with gear handle 4 above tooth bar 3, gear handle 4 is provided with tooth 5 and is meshed with the tooth 6 of tooth bar 3, also is provided with handle 7 and rotating shaft 8 simultaneously on gear handle 4.Make gear handle 4 around the shaft 8 when rotating by pulling handle 7, then tooth 5 can and tooth 6 engagements, and then drive the elastic force that locking bar 1 overcomes spring 2 and move.
An embodiment of the present utility model as shown in Figure 2, shown in it is the mainframe box 9 of a computer, the bonnet 10 of this mainframe box is provided with switching device, thereby can make bonnet 10 relative mainframe boxes 9 do the switch motion.One end of bonnet 10 is connected on the mainframe box 9 by rotating shaft, and the other end is connected on the mainframe box by switching device.This switching device as mentioned above, locking bar 1 is arranged on the inboard of bonnet 10, it links to each other with an end of spring 2, and the other end of spring 2 is fixed on the cabinet casing.Also be provided with tooth bar 3 on the locking bar 1, be provided with gear handle 4 above tooth bar 3, the tooth 5 that gear handle 4 is provided with is meshed with the tooth 6 of tooth bar 3, also is provided with handle 7 and rotating shaft 8 simultaneously on gear handle 4.Make gear handle 4 around the shaft 8 when rotating by pulling handle 7, then tooth 5 can and tooth 6 engagements, thereby the elastic force that makes locking bar 1 overcome spring 2 moves.As shown in Figure 3 and Figure 4, one or more latches 11 are set on locking bar 1, be provided with simultaneously the snap close of equal number on the cabinet casing with respect to the position of latch, latch is inserted in and makes bonnet 10 be fixed on the mainframe box 9 in the snap close at ordinary times under the active force of spring 2.
When needs are opened cabinet bonnet 10, make gear handle 4 around the shaft 8 when rotating by pulling handle 7, then tooth 5 can mesh with tooth 6, thereby the elastic force that makes locking bar 1 overcome spring 2 moves, simultaneously make that also latch spins off from snap close, further thereby pulling handle 7 makes bonnet 10 carry out pivoted with respect to cabinet casing 9, thereby can use less power bonnet 10 can be opened.
In the present embodiment, locking bar 1, spring 2 are arranged on the inboard of bonnet 10, and the gear parts in the gear handle 4 is arranged on the inboard of bonnet 10, and handle 7 is located at the outside of bonnet 10.And handle 7 is made laminar to save the space, the clasp shape is arranged in the end of handle 7 simultaneously, only need so in use to stretch into clasp with a finger, drive handle 7, gear handle 4 and locking bar 1, utilize gear-driven lever principle, the elastic force that overcomes spring 2 is extracted latch out from snap close.Certainly handle 7 also can be other known shapes, as simple sheet, shaft-like etc.
For above-described execution mode; it only is to be used to explain the utility model; to the utility model is illustrative; rather than it is restrictive; in spiritual scope of the present utility model, can also carry out multiple variation, produce numerous embodiments; for example cabinet also can be other electronic equipments such as DVD player etc., all should fall into the protection range of the utility model requirement.
