Specific embodiment
Fig. 1 shows that a cabinet (chassis) 20 for the embodiment of the present invention is installed by a pair of of sliding rail assembly 22 to a rack
(rack) 24, and the opening travel length of the sliding rail assembly 22 is fully to be unfolded, and keeps the cabinet 20 total by a pair of sliding rail
It can be fully moved to outside the rack 24 at 22.
Fig. 2 shows that the embodiment of the present invention is adjusted shortening through the length of 22 opening travel of sliding rail assembly, makes the cabinet 20
The a part that can only be moved to outside the rack 24, the operation mode relative to Fig. 1 only occupy lesser unlatching space.
Fig. 3 shows that the sliding rail assembly 22 of the embodiment of the present invention includes one first rail 26, one second rail 28 and a third rail 30.
Wherein, which there is wall 32a on one first, one first lower wall 32b and one first side wall 34 to be connected to the wall on first
Between 32a and the first lower wall 32b.In addition, first rail 26 has a stopper 36, the of first rail 26 is e.g. set
One side wall 34.Second rail 28 is movably connected with first rail 26, which has on one second under wall 38a, one second
Wall 38b and one second side wall 40 are connected to this on second between wall 38a and the second lower wall 38b.The third rail 30 actively connects
Connect second rail 28.
Fig. 4 further displays a clamping piece 46 and connects first rail 26.In addition, first rail 26 has a fisrt feature 48
With a second feature 50, and the clamping piece 46 be linearly connected to first rail 26 fisrt feature 48 and second feature 50 it
Between.Wherein, which there is one first barricade 52 and one second barricade 54 to be located at first rail 26 respectively with a distance
The two sides of fisrt feature 48.
Fig. 5 further displays a block piece 56 and connects second rail 28, and specifically, the block piece 56 is living by a connection piece 58
The second rail 28 is connected dynamicly and an elastic component 60 generates an elastic force to the block piece 56, and the block piece 56 is made to respond the elastic component 60
Elastic force and opposite second rail 28 is located at a predetermined position.Wherein, which has a hole 42, be e.g. located at this
A part of second side wall 40 of two rails 28, the block piece 56 can be across the hole 42 of second rail 28 towards first rail 26.
Fig. 6 further displays the third rail 30 with an abutment feature 44.
Fig. 7 further displays the clamping piece 46 with an elongated hole 62, passes through the elongated hole 62 by a connection piece 64
A part connects first rail 26, keeps the clamping piece 46 operable in a limited space intrinsic displacement with respect to first rail 26.
Fig. 8 shows that opposite first rail 26 of the second rail 28 of the sliding rail assembly 22 of the embodiment of the present invention is in a stowed position
K.On the other hand, which responds the elastic force of the elastic component 60 and opposite second rail 28 is located at one first predetermined position P1,
Under the first predetermined position P1 state, the abutment feature 44 of the third rail 30 is towards the block piece 56.Therefore, when the third rail
When 30 opposite second rails 28 pull out displacement toward an opening direction D from stowed position K, by the abutment feature of the third rail 30
44 are butted on the block piece 56, and second rail 28 is enable to be displaced by 30 synchronous drive of third rail.
Fig. 9 and Figure 10 show that the clamping piece 46 of the embodiment of the present invention is operably connected the block piece 56, makes 56 phase of block piece
From first predetermined position P1 one second predetermined position P2 is moved to second rail 28 and towards the stopper of first rail 26 36.
Wherein, one of the clamping piece 46 and the block piece 56 have an inclined guidance part 66, and the present embodiment is that have with the clamping piece 46
For the guidance part 66, the block piece 56 is made to be readily susceptible to be moved to from first predetermined position P1 by the guiding of the guidance part 66
Second predetermined position P2.Under the second predetermined position P2 state, which is directed towards the stopper 36 of first rail 26.
On the other hand, under the second predetermined position P2 state, the abutment feature 44 of the third rail 30 is not re-directed towards the block piece 56.
Figure 11 is further illustrated under the second predetermined position P2 state, when second rail 28 is with respect to 26 court of the first rail
When opening direction D is displaced, it is butted on the stopper 36 of first rail 26 by the block piece 56, makes second rail 28 with respect to first rail
26 cannot be displaced along opening direction D.Also that is, through this operation mode, the opening travel that can adjust shortening sliding rail assembly is long
Degree, to meet different environment use demands, such as when that need to operate in confined space, such operation mode can meet and make
Use demand.
Figure 12 is further illustrated under the second predetermined position P2 state, because the abutment feature 44 of the third rail 30 is not
It is re-directed towards the block piece 56.So only the third rail 30 can be displaced with respect to second rail 28 toward opening direction D, and this second
Rail 28 cannot be displaced with respect to first rail 26 along opening direction D.
Certainly, as shown in figure 8, the clamping piece 46 is also operable to no longer guide the block piece 56 displacement, borrow the block piece 56
It helps the elastic force of the elastic component 60 and is moved to first predetermined position P1 from second predetermined position P2 with respect to second rail 28, this
When, which is not re-directed towards the stopper 36 of first rail 26, and reverts to the abutment feature 44 of the third rail 30 towards the gear
Part 56.Therefore, when the third rail 30, which is pulled out with respect to second rail 28 from stowed position K toward opening direction D, to be displaced, by
The abutment feature 44 of the third rail 30 is butted on the block piece 56, and second rail 28 is enable to be displaced by 30 synchronous drive of third rail.Thoroughly
This operation mode is crossed, can adjust the original opening travel length for restoring sliding rail assembly, to meet different environment use demands.
According to above explanation, it is known that enhancement effect of the invention is with advantage: can adjust the unlatching of sliding rail assembly
Stroke length, and can be in response to the demand of different use environments.
Although the present invention is described with reference to current specific embodiment, those of ordinary skill in the art
It should be appreciated that above embodiment is intended merely to illustrate the present invention, can also make in the case where no disengaging spirit of that invention
Various equivalent change and modification out, therefore, as long as to the variation of above-described embodiment, change in spirit of the invention
Type will all be fallen in the range of the claim of this application book.
