The specific embodiment
Shown as shown in Figure 1, Figure 2, the slide rail assembly of first embodiment of the invention comprises one first rail 10; One second rail 12 is slidably connected to this first rail 10; One slip pearl groove 14 is installed between this first rail 10 and this second rail 12, to assist the slip of these the second rail 12 relative these the first rails 10; And one supporting seat 16 be installed on the front end of this first rail 10, to support this second rail 12 in this end place, and there is a block effect when this second rail 12 is pulled out, and this second rail 12 is defined as a longitudinal L along the glide direction of the length of this first rail 10.Wherein:
And read Fig. 3, this first rail 10 comprises one first wall 18, relative this first wall 18 of one second wall 20 and a side wall 22 and connects this first wall 18 and this second wall 20, wherein, this side wall 22 and this first wall 18, the second wall 20 common definition one passages 24, and this first rail 10 has an open end 26 and is positioned at this passage 24 fronts, this open end 26 comprises a stop section 28 and is positioned on this side wall 22, and an installing hole 30.This installing hole 30 can be paired or single, and it is paired in legend, disclosing.
This second rail 12 is connected in the passage 24 of this first rail 10 actively, and it comprises wall 32 on, once wall 36 connects wall 32 and this lower wall 34 on this in relative this lower wall 32 and one of wall 34; Separately, also comprise a limited part 38 and be arranged on the middle wall 36 of this second rail 12.Wherein, this limited part 38 comprises a lock section 40, an elastic force pin 42 and is butted on the lower wall 34 of this second rail 12 and an action bars 44 between this lock section 40 and this elastic force pin 42, mat is pulled this action bars 44, can make these lock section 40 displacements and relatively these supporting seat 16 solutions pull, this second rail 12 can be dismantled from this first rail 10.
And read Fig. 3, and this slip pearl groove 14 is to be arranged on actively this first rail 10, it comprises a travelling carriage 46 and a plurality of ball 48 is arranged on this travelling carriage 46.
And read Fig. 4, this supporting seat 16 is to be arranged on actively the passage 24 of this first rail 10 and corresponding to this open end 26, it comprises one first support portion 50, relative this first support portion 50, one second support portion 52, sidepiece 54 connections this first support portion 50 and this second support portion 52, and a block 56 is connected in this sidepiece 54.Wherein, this first support portion 50 and the second support portion 52 are clasped by the first wall 18 of this first rail 10 and the second wall 20, and between this sidepiece 54 and the stop section 28 of this first rail 10, comprise a buffer body 58, and at least one installation portion 60 is installed to installing hole 30 that should the first rail 10.Preferably, the longitudinal length of this installing hole 30 is greater than the longitudinal length of this installation portion 60.Preferably, this buffer body 58 is to be connected in this sidepiece 54, and for having the strip of at least one bending segment, and the stop section 28 of this first rail 10 is connected to form an accommodation hole 62, is placed in this accommodation hole 62 and is butted on mutually this stop section 28 for this bending segment.
Fig. 5 shows the state that relative this first rail 10 of this second rail 12 fully pulls out, wherein, this limited part 38 can move with this second rail 12, in the time that this limited part 38 arrives this supporting seat 16, lock section 40 with this limited part 38 only offsets corresponding to the block 56 of this supporting seat 16, can make the pull-out of this second rail 12 there is a block effect, and unlikely disengaging.
Again, as shown in Figure 5, when the block 56 of this supporting seat 16 is collided with a larger power by the lock section 40 of this limited part 38, further consult Fig. 6 and Fig. 7, because the installation portion 60 of this supporting seat 16 is movably in the installing hole 30 of this first rail 10, but not fix, therefore in the moment of collision, this installation portion 60 can be interior limited mobile at this installing hole 30, and this sidepiece 54 is that the stop section 28 of this first rail 10 relatively shifts near, by this, utilize this buffer body 58 to be butted on the stop section 28 of the first rail 10, and this buffer body 58 can be extruded and strain, can reduce its collision power and the sound producing.
Fig. 8 shows the configuration kenel of the present invention's the second preferred embodiment, this supporting seat 200 comprises an elongated slot 202, this first rail 204 comprises a fixing hole 206, and comprise a steady pin 208 through this elongated slot 202 and be fixed in this fixing hole 206, and the longitudinal length of this elongated slot 202 is greater than the diameter of this steady pin 208 through the shank 210 of this elongated slot 202.By this, this supporting seat 200 can utilize its elongated slot 202 to do limited movement relative to this first rail 204.
Fig. 9 and Figure 10 show the configuration kenel of the present invention's the 3rd preferred embodiment, the buffer body 302 of this supporting seat 300 is for bulk and have a protruding grain 304, and the stop section 308 of this first rail 306 is set as the hole embedding for this protruding grain 304, to should hole and to be provided with a groove 310 accommodating for these buffer bodies 302, and these buffer body 302 parts be stretched into the installing hole 312 of this first rail 306 and are butted on the installation portion 314 of this supporting seat 300.By this, utilize this buffer body 302, still can produce and be extruded and the buffering effect of strain.
Figure 11 shows the configuration kenel of the present invention's the 4th preferred embodiment, the buffer body 402 of this supporting seat 400 is for adopting spring assembly, and the stop section 406 of this first rail 404 is connected to form an accommodation hole 408, is placed in this accommodation hole 408 and is butted on mutually this stop section 406 for this spring assembly.By this, utilize the buffer body 402 of this form of springs still can produce the buffering effect of elastic compression.
According to above explanation, known enhancement effect of the present invention and advantage are:
Utilization can be mobile by a small margin supporting seat and coordinate this buffer body, it can be in the time that slide rail fully pulls out, and effectively reduces its collision power and sound, and supporting seat is original is used for the function that block slide rail can not depart from and also can possesses.
Although the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, in the situation that not departing from spirit of the present invention, also can make variation and the modification of various equivalences, therefore, as long as the variation to above-described embodiment, modification all will drop in the scope of the application's claims within the scope of connotation of the present invention.
