Although above-mentioned locker can realize fixing the reliable of cabinet, there is the problem of function singleness in it.Due to the equipment compartment often limited space of aircraft; being on the increase in addition along with the equipment of record; the space that can be used for carrying out cabinet plug operation is more and more less; but above-mentioned locker but cannot realize pulling out helping of cabinet; for the cabinet equipment that contact engaging and separating force is larger; usually also need to arrange corresponding extracting apparatus specially, this is obviously extremely inconvenient, uses the cabinet bracket system of above-mentioned locker and rack certainly also to there is same inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of avionics electronics equipment cabinets, to solve existing avionics electronics equipment cabinets in the awkward problem of little space situations.
In order to solve the problem, avionics electronics equipment cabinets of the present invention is by the following technical solutions: avionics electronics equipment cabinets, comprise cabinet and be located at the cabinet bracket system in cabinet, cabinet bracket system comprises bracket and locker, locker comprises connecting rod, length adjustment mechanism and the locking gear be located between length adjustment mechanism and connecting rod, front end and the bracket of connecting rod are hinged, length adjustment mechanism comprises knob shell and latch closure, knob shell by Screw assembly on connecting rod, latch closure to be enclosed within connecting rod and can on connecting rod fore-aft travel, before and after knob shell and latch closure, anticreep is assembled together, described latch closure is fixedly connected with extending sleeve, the front portion of extending sleeve is provided with the hooking structure for coordinating with corresponding cabinet hook, on extending sleeve, being equipped with of anticreep can the lock nut of fore-aft travel forward, the front end of lock nut is provided with the opening for suppressing the locking bail on corresponding cabinet, biasing springs is top-loaded with between latch closure and lock nut, biasing springs urged forward lock nut.
Described biasing springs is ripple spring.
The anterior outside wall surface of described extending sleeve is provided with draw-in groove, and described hooking structure is made up of the front side cell wall of draw-in groove.
The rear side cell wall of described draw-in groove forms the boosting structure that can promote the reach of corresponding cabinet.
Assemble porose back-up ring in described lock nut, the outside wall surface of extending sleeve is provided with the cannelure corresponding with described hole back-up ring, and lock nut passing hole back-up ring was assemblied on extending sleeve with coordinating of described cannelure.
In the process using rack of the present invention, when cabinet extracted by needs, corresponding cabinet is hooked by the hooking structure on extending sleeve, by lock nut, the position that cabinet coordinates with extending sleeve is locked between the hooking structure of extending sleeve and lock nut, now namely extending sleeve is driven to move backward together by latch closure by rotating knob shell, and then extract cabinet backward by extending sleeve, in the process of extracting, even if pull out force is larger, under the effect of lock nut, hooking structure also can not produce the phenomenon generation skidded and then order about cabinet and upwarp, do not need the extracting apparatus preparing other in addition, thus solve existing avionics electronics equipment cabinets in the awkward problem of little space situations.
Accompanying drawing explanation
Fig. 1 is the structural representation (removing cabinet) of the embodiment of avionics electronics equipment cabinets;
Fig. 2 is the structural representation of locker;
Fig. 3 is that locker is helping the schematic diagram under the state of pulling out.
Embodiment
The embodiment of avionics electronics equipment cabinets, as shown in Figure 1-2, this avionics electronics equipment cabinets comprises cabinet (not shown) and bracket system, and bracket system is fixedly assemblied in cabinet.
Comprise bracket 13 and locker 101, connecting rod 11, length adjustment mechanism and the locking gear be located between length adjustment mechanism and connecting rod.
Connecting rod 11 is screw rod, and its front end is provided with hinge hole 12, and by hinge hole 12 hinge mounted on bracket 13.The structure of connecting rod 11 is prior art, and it will not go into details herein.
