The invention belongs to electronic equipment machinery technical field of structures, it is related to that the front locking device of torque operation can be determined.The present invention realizes that torque wrench can quantitatively tighten the function of operation by being changed to outer six sides, plum blossom shape, and increase the clip of adaptation for the structure of the circular strip annular knurl of existing preceding locking shape.It is locked at before plum blossom outside newly-increased torque spanner operating function, is also compatible for past manually tightening function.The method structure is simple, convenient and efficient, solve before existing A type locking can only hand operation, the technical problem of no legal torque installation, the connection reliability between LRU and mounting rack improved.
Description
Technical field
The invention belongs to electronic equipment machinery technical field of structures, it is related to that the front locking device of torque operation can be determined.
Background technique
The A type locking apparatus that Field Replaceable Unit as defined in GJB441 standard (referred to as: LRU) uses at present, usually will
The leading portion of preceding tight device is designed as annular knurl state, with manually tightening.This mode of operation has the following problems:
A. it manually tightens, the hand strength of people is limited, it is difficult to ensure that front locking device has been tightened in place.
B. locking before hand is twisted, screw-down torque size can not quantify, in order to guarantee enough screw-down torques, frequently with pliers
It is tightened after clamping, not only be easy to cause scuffing, and still remained locking apparatus and twist that not tight or screw-down torque is excessive causes LRU
The possibility of Joint failure.
Summary of the invention
The purpose of the present invention: it is tightened to solve the problems, such as before A type that torque determine in locking, proposes that one kind can determine torque operation
Front locking device.
Technical solution of the present invention: can determine the front locking device of torque operation, be cooperated using rectangle pawl, by increasing bullet
Property retaining mechanism, realize lockwheel unscrew function；The elastic locking mechanism includes pin, screw rod, lock, swivel nut, lockwheel, gear
Circle, spring；It can slide, but not can be rotated axially along a screw between lock and screw rod；On circumference between lock and lockwheel, design
There is the back-off of final peak sawtooth shape retaining, between swivel nut and lockwheel, designing has spring, and in normal use, which provides elastic force, will
Lockwheel is pressed in the back-off of lock, and the back-off of final peak sawtooth shape retaining can prevent the unintended of retaining mechanism from loosening；Lockwheel and
It can radial small range sliding between swivel nut；When dismantling front locking device, lockwheel can be pulled outward, so that the back-off of zigzag retaining is de-
From the rotation of another mistake hour hands can unclamp preceding retaining mechanism.
The lockwheel can be set to hexagon or quincunx.
The front locking device for determining torque operation further includes clip corresponding with lockwheel shape, and clip front end is provided with
Groove corresponding with lockwheel shape, the tail end of clip are provided with countersunk head；Make in order to which the front locking device of torque operation can be determined
With.
The present invention has the advantage that effect: present invention employs two kinds of novel contour structures, by will it is existing before locking it is outer
The structure of the circular strip annular knurl of shape is changed to outer six sides, plum blossom shape, and increases the clip of adaptation, realizes that torque wrench can be determined
Amount tightens the function of operation.It is locked at before plum blossom outside newly-increased torque spanner operating function, is also compatible for past manually tightening function
Energy.The method structure is simple, convenient and efficient, solve before existing A type locking can only hand operation, the skill of no legal torque installation
Art problem, the connection reliability between LRU and mounting rack improved work well by product actual verification.

Specific embodiment
The following further describes the present invention with reference to the drawings:
As shown in Fig. 2, retaining mechanism before six sides, on the basis of locking before previous A type, six side's shapes of Curve guide impeller
Lockwheel can cooperate with six side's clips, be designed as six square boss on the right side of six side's clips, can be with the standard cartridges of torque spanner
Cooperation by setting the moment values of torque spanner, and operates locking mechanism before six sides, and preceding retaining mechanism is determined in realization
Torque tightens function.
As shown in Fig. 3, retaining mechanism before plum blossom, on the basis of locking before the previous A type, Curve guide impeller plum blossom shape
Lockwheel can be cooperated with plum blossom clip, be designed as six square boss on the right side of six side's clips, can be with the standard cartridges of torque spanner
Cooperation by setting the moment values of torque spanner, and operates locking mechanism before six sides, and preceding retaining mechanism is determined in realization
Torque tightens function.In addition, be locked at before plum blossom outside newly-increased torque spanner operating function, also it is compatible for past manually tightening function
Energy.
As shown in Fig. 4, two kinds of locking devices and corresponding clip have made exemplar, and have carried out verification experimental verification, are setting
It under the conditions of determining torque, may be implemented to determine torque to tighten operation, solve previous hand operation or pliers clamp operation bring is owed
Torque crosses the technical problems such as torque, scuffing, can effectively improve the reliability of LRU product structure installation and interconnection.
When it is implemented, lockwheel uses two kinds of contour structures, by by the circular strip annular knurl of existing preceding locking shape
Structure is changed to outer six sides, plum blossom shape, and increases the clip of adaptation, i.e. locking includes six side's lockwheels before six sides, corresponding packet
Include six side's clips.Locking includes a plum blossom lockwheel before plum blossom, and corresponding includes a plum blossom clip.Realize torque wrench
The function of operation can quantitatively be tightened.It is locked at before plum blossom outside newly-increased torque spanner operating function, is also compatible for past unarmed twist
Tight function.The method structure is simple, convenient and efficient, solve before existing A type locking can only hand operation, no legal torque installation
Technical problem, the connection reliability between LRU and mounting rack improved.
The six side's lockwheels for including are locked before six sides, maximum shape is hexagon shape, the hexagon shape and six
Six square groove of left end of square clip cooperates, and fit clearance control is designed as six squares on the right side of 0.2 millimeter, six side's clips, can be with power
The standard cartridges compounding practice of square spanner.
The plum blossom lockwheel for including is locked before the plum blossom, maximum shape is six valve plum blossom shapes, the plum blossom shape
Cooperate with the left end plum blossom trough of plum blossom clip, it is heavy that fit clearance control is designed as six squares on the right side of 0.2 millimeter, plum blossom clip
Head, can be with the standard cartridges compounding practice of torque spanner.Having 6 diameters in the lockwheel edge designs of above two form is 2.5
Small blind hole, be used for loss of weight.
