Illustrate, in embodiments of the invention other, case lid 200 and cabinet 300 may be set to be the form on inclined-plane, same
It is able to achieve the effect of above-mentioned abutting.
Please continue to refer to Fig. 7, guide sleeve 120 is provided in the axial direction with through-hole 127, the lower part 126 of the second end close to second
One end of fixed ring 140 offers the receiving hole 1261 being connected to through-hole 127, and the number of receiving hole 1261 is 3,3 receivings
Hole 1261 is uniformly distributed centered on the axis of through-hole 127.
It is provided with the matched bead 1262 of size in each receiving hole 1261, is provided with and each receiving hole in through-hole 127
The actuator 1291 that bead 1262 cooperates in 1261, the actuator 1291 are set to separate second fixed ring 140 of bead 1262
Side.Referring to Fig. 4, actuator 1291 drives when moving when 1291 stress of actuator to the direction close to the second fixed ring 140
It moves each bead 1262 to move to the direction far from through-hole 127 and partially stretch out accommodating chamber, since the first elastic component 134 is to guide sleeve
120 generate the power for making it away from the second locking device, to make the portion extrusion taper hole 141 of the stretching receiving hole 1261 of bead 1262
Inner wall prevent guide sleeve 120 be detached from the second fixed ring 140 with realize locking.Referring to Fig. 5, when actuator 1291 is not to bead
1262 when being squeezed, and the part that bead 1262 stretches out receiving hole 1261 can move under the extruding of the inner wall of taper hole 141 and can hold
Receive hole 1261, the second end 124 can pass freely through taper hole 141 and be detached from the second fixed ring 140 to realize unlock.
In the present embodiment, the bead 1262 and actuator 1291 are the generally equal steel ball of size, extrusion stability
Property it is high, wearability is good.141 sidewall extrusion of extruding driving and taper hole of 3 beads 1262 being uniformly distributed convenient for actuator 1291
Return motion.It should be noted that the number of receiving hole 1261 and bead 1262 is distinguished in other embodiments of the invention
For at least one, such as can be 1,2,3,4 or other, such as when the number of receiving hole 1261 be 1 when, bead 1262
Number similarly can be 3, also cannot be one, as long as being able to achieve the part of at least one bead 1262 with actuator
1291 squeeze stretching receiving hole 1261 and can reply receiving hole 1261 under 141 sidewall extrusion of taper hole.
In the present embodiment, the outer wall of the lower part 126 of the second end is also provided with annular groove 1263, and annular groove 1263 is arranged
In the close first end 121 of receiving hole 1261 side and with one end of the close first end 121 of each receiving hole 1261 connect
It is logical, washer 1264 is detachably provided in annular groove 1263.The setting of washer 1264 can prevent bead 1262 in actuator
Receiving hole 1261 is completely disengaged under 1291 driving effect;While washer 1264 and the dismountable connection type of annular groove 1263 are just
Bead 1262 is placed in receiving hole 1261 when installation.It should be noted that in other embodiments of the invention, it can also
Annular groove 1263 to be set to the side close to the second fixed ring 140 of receiving hole 1261, or the two of receiving hole 1261
Side is respectively provided with annular groove 1263 and washer 1264.
Please continue to refer to Fig. 5 and Fig. 6, guide sleeve 120 is sheathed on outside guide post 110, which is used for against actuator 1291
Separate bead 1262 side and be slidably matched with through-hole 127.
Through-hole 127 includes first through hole 128 and the second through-hole 129, and first through hole 128 is opened in first end 121, and second
Through-hole 129 is opened in the second end 124.First through hole 128 is connected to the second through-hole 129, and the internal diameter of first through hole 128 is greater than the
The internal diameter of two through-holes 129.
First end 121 offers the sliding slot 123 being connected to first through hole 128, and sliding slot 123 has opposite starting point 1231
With stop 1232, the distance of starting point 1231 to the second end 124 is greater than the distance that stop 1232 arrives the second end 124.
Referring to Fig. 10, guide post 110 includes the upper guide post 111 cooperated with first through hole 128 and cooperates with the second through-hole 129
Lower guide post 113.Upper guide post 111 is provided with the lock pin 112 cooperated with sliding slot 123.
When rotary guide 110 makes lock pin 112 slide into stop 1232 from starting point 1231, lower guide post 113 is towards close to second
The direction of fixed ring 140 moves and the actuator 1291 is driven to carry out squeezing realization locking to bead 1262;When rotary guide 110
When lock pin 112 being made to slide into starting point 1231 from stop 1232, lower guide post 113 moves just towards the direction far from the second fixed ring 140
It is resetted in bead 1262 and realizes unlock.In the present embodiment, one end far from lower guide post 113 of upper guide post 111 is provided with handle
114, convenient for carrying out rotation process to guide post 110.
In the present embodiment, sliding slot 123 includes 1233 He of first end face being connected between stop 1232 and starting point 1231
Second end face 1234, first end face 1233 are set to the side of the close first end 121 of second end face 1234.Second end face
One end of 1234 close stop 1232 is equipped with the locating part 1235 protruded towards second end face 1234, for hindering rotation to end
The lock pin 112 of point 1232 is moved towards the direction close to starting point 1231.Second end face 1234 offers and 1235 position pair of locating part
The groove 1236 answered reduces first end face 1233 to the distance of second end face 1234, sliding slot 123 convenient for passing through for lock pin 112
It is higher with the fitness of lock pin 112.
Further, be provided in first through hole 128 for drive lock pin 112 far from first end 121 second elasticity
Part 1281, the second elastic component 1281 is spring in the present embodiment.Second elastic component 1281, which is sheathed on lower guide post 113, makes guide post 110
With the trend moved to the direction far from the second end 124, when lock pin 112 is located at stop 1232, lock pin 112 is in the second bullet
Property part 1281 under the action of squeeze first end face 1233, the position-limiting action of locating part 1235 improves;When lock pin 112 passes through locating part
When first starting point 1231 moves after 1235, the second elastic component 1281 can speed up the sliding of lock pin 112.
The setting of above-mentioned locating part 1235 and the second elastic component 1281 can effectively avoid the lock pin 112 under locking state
Rebound, while allowing the tilt angle for increasing sliding slot 123 to reduce the rotation angle of locking operation.In the present embodiment, it rises
Point 1231 to the corresponding rotation angle of stop 1232 be generally 30 °, i.e. bus where starting point 1231 and stop 1232 place
Substantially 30 ° of the corresponding central angle of the corresponding arc surface of bus, which keeps locking operation simpler.
In conclusion fixing piece 100 provided by the invention, is arranged limit in one end of the close stop 1232 of sliding slot 123
Part 1235 increases the resistance that lock pin 112 slides into starting point 1231 from stop 1232, and lock pin 112 can be effectively prevent to reply easily
The loosening of locking state is caused to starting point 1231, while being conducive to reduce the corresponding rotation angle of sliding slot 123.Family provided by the invention
With proof cabinet 10, using above-mentioned fixing piece 100, locking operation rotation angle is small, locking state is stable, good clamping effect.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
