Description
Technical field
The present invention relates to pin joint latch hook quick-release component, it is mainly used in the locking of airborne cabinet.
Background technology
Current airborne locking device uses A type locking apparatus more, as shown in Figure 1.A types locking apparatus by preceding tightening component and
Tightening component forms afterwards, and rear tightening component realizes with the guide on the taper pin and cabinet on mounting bracket, preceding tightening component by
The parts such as the latch hook on hinge, pin, preceding latch assembly and cabinet on mounting bracket form.
It is rigidly connected due to being used between hinge and mounting bracket, and the application of a surface passed through between preceding locking and latch hook is realized
Coordinate, and preceding locking at present is typically designed as rotating up 20 °, therefore, latch hook and two curved surfaces are only being designed and processed
In the case of completely without mistake, application of a surface could be realized.
But during processing and use, deviation and abrasion will necessarily be produced, thus design angle it is difficult to ensure that, cause to connect
Contact portion divides surface stress excessive, even results in cabinet and mounting bracket Joint failure.
The content of the invention
In order to solve problem present in background technology, the present invention provides a kind of pin joint latch hook quick-release component.The pin joint is locked
Hook quick-release modular construction is simple, effectively eliminates the fit clearance between latch hook and preceding latch assembly, avoids latch hook and preceding locking group
Amplification between part, improve the reliability that structure interconnects between cabinet and mounting bracket.
The particular technique solution of the present invention is as follows：
The pin joint latch hook quick-release component is locked before including hinge, pin joint latch hook and pin joint, the pin joint latch hook fixed setting
Lock on case front panel, before pin joint and be hinged by pin and hinge, lock before pin joint and be adapted with pin joint latch hook, before pin joint
Pin joint latch hook is locked towards cabinet installation direction after locking tightening.
The pin joint latch hook includes latch hook and fixture, and fixture is used to latch hook being fixedly connected with case front panel, locked
Hook is integrated part and angle be present with fixture, is mutually fitted with the angle between fixture when tightening is locked before angle angle and pin joint
Match somebody with somebody.
Locking includes screw rod before the pin joint, and locking shell and movement parts is provided with screw rod, lock shell and screw rod it
Between using threaded connection, movement parts are socketed on screw rod, promote movement parts to be moved on screw rod during locking shell movement, motion
Pin is provided with part, pin central axis is adapted in screw stem, pin with latch hook, and pin should block when locking completely
Enter in latch hook.
Advantages of the present invention is as follows：
The pin joint latch hook quick-release component can effectively eliminate the fit clearance between existing latch hook and preceding locking, be A types rigidity
The upgrading products of hinge, wide adaptability, the connection reliability of A type Quick-disassembling devices can be effectively improved.
The pin joint latch hook quick-release component deft design, small volume is in light weight, and cost is low, and compatibility is good, can be in airborne production
Promoted the use of in product.
Brief description of the drawings
Fig. 1 is existing A types locking apparatus structural representation；
Fig. 2 is schematic structural view of the invention.
1- pin joint latch hooks, 2- guides, base before 3-, 4- hinges, 5- pins, lock before 6- pin joints.
Embodiment
Solve accompanying drawing below to be described in detail the present invention, as shown in Figure 2：
Cabinet is attached by guide and connector, and cabinet is placed on guide after the completion of connection, in order to avoid because
Vibration causes cabinet to be skidded off from guide or being connected loosening with rear side connector causes reliability to reduce, the bottom on the outside of guide
Portion is provided with preceding base, and sets hinge on preceding base, and for installation locking device, locking device is used for through case front panel
Cabinet and connector and guide are held out against, therefore, locking device needs to cabinet while applied towards connector and guide
Power.
The pin joint latch hook quick-release component is mainly made up of the parts such as locking before hinge, pin, pin joint latch hook, pin joint.Pin
Connect latch hook to be fixedly installed on case front panel, lock before pin joint and be hinged by pin and hinge.
Wherein pin joint latch hook includes latch hook and fixture, and fixture is used to latch hook being fixedly connected with case front panel, locked
Hook is integrated part and angle be present with fixture, and the angle is mainly used in being applied with when locking locks cabinet completely before pin joint
The power of both direction is stated, is adapted when therefore, before angle angle and pin joint locking tightening with the angle between fixture.
Locking includes screw rod before pin joint, and locking shell and movement parts are provided with screw rod, and screw rod is cut with scissors by pin and hinge
Connecing, lock using be threadedly coupled between shell and screw rod, movement parts are socketed on screw rod, during rotational lock shell, locking shell
Promote movement parts to be moved on screw rod, be provided with pin in movement parts, pin central axis in screw stem, pin with
Latch hook is adapted, and pin should be caught in latch hook when locking completely.
The pin joint latch hook quick-release component is essentially identical with conventional standard A type locking device application method, first puts cabinet
Enter mounting bracket, lock and lift before, unscrew and it is connected with the latch hook of cabinet, according to given screw-down torque, twist clockwise
The shell of latch assembly before tight, until tightening, at this moment pin joint latch hook and preceding locking realizes that structure interconnects by the pin of both sides.
Unloading process is opposite.
The pin joint latch hook quick-release component meets outfield three-level maintenance system, and LRU scenes quick-replaceable can be achieved.The present apparatus is set
Timing has taken into full account that the vibration environment of computer uses needs.After cabinet and preceding latch assembly are installed in place, according to cabinet
With the respective error of mounting bracket, by latch assembly before pin joint latch hook and pin joint, adaptive cooperation is realized, automatic capturing, is coordinated
Angle can each part error adjust automatically, cooperation stress surface be two appropriate semi-circular cylindricals according to cabinet and mounting bracket
Face, the preceding locking after improvement remain in that auto-lock function, avoid releasing.After latch hook improves, front and back up and down can be not only realized
To cooperation, and in left and right directions, reduce fit clearance, realize the fastening of cabinet left and right directions.
In long-term use, when forward and backward locking apparatus wears, gap can be realized by latch assembly before tightening
Eliminate, avoid the further amplification of vibration stress.The pretightning force that latch assembly is kept before pin joint can resist vibratory impulse, disappear
Except stress raisers, it is ensured that the reliable interconnection of cabinet and mounting bracket.
The pin joint latch hook quick-release component includes two pin joint structures, first be hinge and preceding latch assembly screw rod it
Between, second is latch structure itself the not axial rotary freedom of banking pin nail, therefore can be very square between preceding locking and latch hook
Just the safety interconnection realized fastening of the screw rod under different angle, realize between cabinet and mounting bracket.
