Specific embodiment
As shown in Figure 1, the sliding rail assembly of one embodiment of the invention includes one first rail 20, one second rail 22 and a ball
Retainer (ball retainer) 24 is mounted between first rail 20 and second rail 22.Preferably, also including a third rail
26 are movably connected with for first rail 20, to extend the opening travel of the sliding rail assembly.Wherein, which includes one
Upper wall 28a, once wall 28b and a longitudinal wall 30 are connected on this between wall 28a and the lower wall 28b.Wall 28a, the lower wall on this
28b and the longitudinal direction wall 30 define a channel 32, for second rail 22 installation.Adjacent to one gear of front end setting of first rail 20
Seat 34, as shown in Fig. 2, the two sides of the block seat 34 are respectively provided with a butting section 35 and an elastic force foot 36.Second rail 22 can be at this
The channel 32 of first rail 20 is with respect to 20 activity of the first rail.
As shown in Figure 3 and Figure 4, which includes wall 38a on one, once the longitudinal wall 40 of wall 38b and one is connected to this
Between upper wall 38a and the lower wall 38b.Longitudinal wall 40 of second rail 22, such as the block piece 42 are also mounted on comprising a block piece 42
It is located between the stopper 44 and the release portion 46 comprising a stopper 44, a release portion 46 and an articulated section 48.Wherein, by one
Articulated part 50 passes through the articulated section 48 of the block piece 42 so that the block piece 42 to be articulated in longitudinal wall 40 of second rail 22.Preferably,
The sliding rail assembly also includes one first elastic component 52 and an operating parts 54.Specifically, first elastic component 52 be arranged in this
Longitudinal wall 40 of two rails 22, to provide an elastic force to the block piece 42, which responds the elastic force of first elastic component 52 and energy
Enough opposite second rails 22 are maintained at a first state S1.The operating parts 54 is movably coupled to second rail 22, and the behaviour
Workpiece 54 includes an operation portion 56 and an abutting part 58, and the abutting part 58 is towards the release portion 46 of the block piece 42, it is preferable that this is supported
One of socket part 58 and the release portion 46 have a guiding face 57, such as the abutting part 58 has a cambered surface, to be easy to drive example
Release portion 46 as pushed against the block piece 42.According to this configuration, which can be to operate the block piece 42 from the first state
S1 is moved to one second state S2, as shown in Figure 5.Preferably, the sliding rail assembly also includes that one second elastic component 60 provides a bullet
Power is to the operating parts 54.In this, which can be mounted on longitudinal wall 40 of second rail 22 by a mounting base 62,
And second elastic component 60 provides an elastic force to the default forced section 64 of operating parts 54, makes the operation portion of the operating parts 54
After 56 are displaced by an external force by operation, when decontroling the external force, which can be responded produced by second elastic component 60
Elastic force, and return back to its initial position.
As shown in fig. 6, the ball distance ring 24 includes wall 66a on one, once wall 66b, a longitudinal wall 68 are connected on this
Between wall 66a and the lower wall 66b and a plurality of rolling members 70 are mounted on the upper wall 66a and lower wall 66b of the ball distance ring 24,
A plurality of rolling members 70 can be ball or idler wheel contact between first rail 20 and second rail 22, to help this second
Smooth degree when rail 22 is with respect to 20 activity of the first rail.In this, the front end of the ball distance ring 24 has a contact portion 72 and one
Clip feature 74.
Fig. 7 to Fig. 9 shows first rail 20 and second rail 22 with respect to the third rail 26 from a collapse state toward a direction D
When (such as extending direction) is drawn out, the present embodiment is to configure the block piece 42 (namely not yet to grasp under first state S1
The state of work, as shown in Figure 4), the position of the stopper 44 of the block piece 42 is the corresponding contact portion 72 towards the ball distance ring 24
And the butting section 35 of the block seat 34, wherein between the contact portion 72 of the ball distance ring 24 and the butting section 35 of the block seat 34
It is the position that is staggered each other.Therefore, when second rail 22 is drawn out with respect to first rail 20 is moved to a predetermined position, the rolling
The contact portion 72 of pearl retainer 24 can be pushed against first by the stopper 44 of the block piece 42, be displaced the ball distance ring 24, the block piece 42
Stopper 44 can further be butted on first rail 20 block seat 34 butting section 35.
Figure 10 shows the rolling when ball distance ring 24 is driven and is moved to close to the front position of first rail 20
The clip feature 74 of pearl retainer 24 can be such that the ball keeps with the mutual clip of elastic force foot 36 on the block seat 34 of first rail 20
Device 24 can temporarily keep and stop a position herein.On the other hand, as shown in figure 11, the stopper 44 of the block piece 42 can be supported further
In the butting section 35 of the block seat 34 of first rail 20, prevent second rail 22 with respect to the first rail 20 from pulling out displacement again.
Figure 12 and Figure 13 shows when the operating parts 54 is operated, the block piece 42 respond the operating parts 54 by operation beat
Displacement, makes the block piece 42 no longer be butted on the butting section 35 of the block seat 34 and can be detached from from the butting section of the block seat 34 35, enable this
Two rails 22 can be unloaded from first rail 20.
According to above explanation, it is known that enhancement effect of the invention is with advantage: being applied to a dismountable sliding rail
Under assembly, through above-mentioned configuration, it can be ensured that the ball distance ring 24 can be driven to the front position of first rail, make this
Displacement between opposite first rail 20 of second rail 22 is more smooth and has good support effect.
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.
