Fill in hole, driver blade 15 is enclosed on swivel nut 12 at the front side of retaining wall 131 and by the gear on swivel nut 12 along 121 blocks, thereafter
Side is provided with ball groove 151 corresponding with transmission steel ball 14, and in the present embodiment, ball groove 151 is driven steel ball 14 positioned at corresponding
Both sides at cell wall relative to the angle of bottom land be different, specifically, it is in swivel nut 12 relative to the precession of locking bar 11
Gradient on direction positioned at the cell wall of front side is more than the gradient of the cell wall of opposite side, so that transmission steel ball 14 is in swivel nut
12 relative to 11 precession of locking bar when be more prone to produce skidding.Tabletting 16, limiter spring 17 and spring supporting cover 18 from forward direction
It is assemblied in successively on swivel nut 12 afterwards, wherein tabletting 16 is to be interposed between limiter spring 17 and transmission steel ball 14 and be pressed in transmission steel ball 14
On, specifically using dished spring assembly, dished spring assembly specifically includes one group of disc spring and is interposed between adjacent disc spring limiter spring 17
Stabilization, spring supporting set 18 by Screw assembly swivel nut 12 rear end, spinning in place after, it is by by rear end
Set tail tooth 181, which closes up, to plough under into the stern notch of swivel nut 12 and realizes locking with swivel nut 12, and limiter spring 17 is in compressing shape
State, it has been mounted in so that limiter spring 17 actually pushes up between swivel nut 12 and tabletting 16, during turncap 13 is rotated, if
The resistance that swivel nut 12 runs into is less than setting value, then can be formed from turncap 13 successively to transmission steel ball 14, driver blade 15 and swivel nut 12
Drive path, by rotating turncap 13 swivel nut 12 can be driven to be rotated relative to locking bar 11, the resistance foot run into when swivel nut 12
When enough big, then it is driven steel ball 14 and is skidded relative to driver blade 15, so as to cut off the transmission of fortune work(.By described above, rotation
Cap 13 together form the biography of limiter square with transmission steel ball 14, driver blade 15, tabletting 16, limiter spring 17 and spring supporting set 18
Motivation structure, the size of institute's limiter square can be adjusted by the decrement and pressure that design limiter spring 17.
The front portions that output set 19 is assemblied in swivel nut 12, it is particularly located at the gear of swivel nut 12 along front, when swivel nut 12 is to reach
When dynamic, then output set 19 travels forward together in the presence of swivel nut 12, in the present embodiment, gear edge and the rear end of output set 19
Between be provided with rotating actuator, rotating actuator is made up of above-mentioned retainer 20 and ball 21, wherein retainer
The side of 20 close ball 21 is provided with ball grooves 201 corresponding with ball 21, after the completion of to be assembled, retainer 20, ball 21
With gear along in substance form structure similar to thrust bearing, thus can avoid output set 19 rotated together with swivel nut 12 and only
Travelled forward with swivel nut 12, wherein ball 21 and retainer 20 are to be fixed on by jump ring 27 on swivel nut 12.In addition, output set 19
On be additionally provided with for on corresponding cabinet locking bail coordinate with promote the locking bail of cabinet push structure, in the present embodiment,
The pushing structure is specifically to be made up of a step surface, and the step surface is then by setting ring in the outside wall surface of output set
Groove, it is made up of the trailing flank of annular groove, when use, can be coordinated by pushing structure with the locking bail on corresponding cabinet and real
Boosting when now being assembled to cabinet.Than the above described structure, it is additionally provided with annular at the rear side of above-mentioned annular groove on output set 19
Stopper slot.
Drive sleeve 23 is securely fitted in the rear end of output set 19 by circlip 28, and its rear end is provided with turn edge, should
Turn edge is located at the rear of ball and anticreep coordinates forward with swivel nut 12, while anticreep is matched somebody with somebody forward with swivel nut 12 so that output covers 19
Close.
Lock nut 24 is assemblied on output set 19, is equipped with hole back-up ring 29 thereon and is covered by hole back-up ring 29 and output
Stopper slot on 19 coordinates and anticreep is assemblied on output set 19, the top of biasing springs 22 be mounted between drive sleeve and lock nut and forward
Lock nut 24 is pushed, in the present embodiment, biasing springs 22 are specifically using ripple spring.

In example, upper fulcrum portion 2510 that lockhole 251 divides to set one on the other, lower fulcrum part 2511 and it is connected in, fulcrum portion
Between transition portion, wherein upper fulcrum portion is located at the front of lower fulcrum part, locking bar 11 passes through bearing pin 31 and lock 25
Lockhole coordinate and hinge mounted on lock 25.
Shown in Figure 10-12 is the use state figure for the cabinet bracket system of rack.Lock 25 is securely fitted in
On bracket 30, cabinet 32 is provided with locking bail 33, when needing to insert cabinet 32 into rack, makes between locking bar 11 and lock 25
Bearing pin 31 is located at the lower fulcrum part of lockhole, precession turncap clockwise, then turncap passes sequentially through steel ball, driver blade, swivel nut, rolling
Pearl, retainer driving output set to coordinate with locking bail carries out boosting to cabinet, so as to complete the push-in to cabinet, when cabinet pushes away
After the completion of entering, then output set suffered resistance moment becomes big, so that steel ball starts to skid relative to driver blade, Jin Erfang
Only cabinet is damaged, and plays a part of protecting cabinet, it should be pointed out that during cabinet is promoted, lock nut is pressed in all the time
On locking bail, so as to prevent that cabinet from being levered up.When needing unloading cabinet, the bearing pin between locking bar and lock is moved to lockhole
Upper fulcrum office, locking bail is hooked by the front side wall of the annular groove on output shaft, then turn turncap backward counterclockwise, then
Turncap pass sequentially through steel ball, driver blade, retainer, Ball Transmission set, jump ring and pull back output set, finally realize to cabinet
Helping for unloading is pulled out, and the first limitation point 101, locking bar and lock are formed during helping and pulling out, at the cooperation position of lock nut and locking bail
The second limitation point 102 is formed at the cooperation position of the rearward end of seat, so as to prevent cabinet from being prized upwards during movement
Rise and damage the electric connector at its rear portion.
In the other embodiments for the cabinet bracket system of rack, dished spring assembly can also not have stabilization, in addition
Dished spring assembly can also be replaced using other types of spring；Described ball and retainer can also directly pass through thrust
Bearing is substituted or omitted.
