The specific embodiment
As shown in Figure 1 to Figure 3, device of the present invention, for comprising slide block 1, slide 2 and collude part 3, and collocation outer rail 4 and in rail 5 and implementing, and middle rail 5 is worn cunning in outer rail 4, wherein slide block 1 comprises side lug 11, clip lug 12, draw-in groove 13, block 14, and with 15 connections of first elastic parts, slide 2 comprises fixture " present embodiment is a protuberance 21; lug 24 and gim peg 25 ", chute 22, polarizing slot 23, and outer rail 4 also correspondence is provided with fixture " present embodiment is a locating slot 41; caulking groove 42; margining tablet 43 and fixing hole 44 ", and then make slide 2 be fixedly arranged on outer rail 4 ends " present embodiment is that protuberance 21 embeds locating slots 41; 24 of lugs embed caulking groove 42; and lug 24 limits are stuck in margining tablet 43 times; and be locked in fixing hole 44 with gim peg 25 company's of wearing slides 2 ", 1 of slide block with side lug 11 embedding cunnings in the chute 22 of slide 2, first elastic parts 15 is located in the chute 22 of slide 2 to make slide block 1 be pulled in the position of correspondence in outer rail 4 ends, slide 2 is located for the clip lug 12 corresponding cards temporarily of slide block 1 with polarizing slot 23, colluding 3 of parts is located on the middle rail 5, and corresponding to slide block 1, collude part 3 and include first hook 31, second hook 32, the articulated section 33 and second elastic parts 34, rail 5 and its secondary rail were 51 during articulated section 33 was articulated in, second elastic parts 34 makes first hook 31 and second hook 32 corresponding supporting in the draw-in groove 13 and the block 14 of slide block 1 under normality, and the adjacent part 3 that colludes is provided with a lug 52 " present embodiment is for going out this lug 52 with secondary rail 51 bending formings " in middle rail 5.
The normal use when operating, extremely shown in Figure 7 as Fig. 4, wherein:
Fig. 4 is that slide rail is under the collapse state, this slide block 1 is positioned at slide 2 rear ends by 15 pullings of first elastic parts, and collude first hook 31 of part 3 and the draw-in groove 13 that second hook 32 is stuck in slide block 1, and be limited to block 14 inboards and " be butted on block 14 mutually " with second hook 32, that is utilize this slide block 1 with collude part 3 mutually embedding support, and rail 5 is located after closing at outer rail 4 in making;
Fig. 5 stretches middle rail 5 relative outer rails 4, before then this colludes part 3 and drives slide blocks 1 and slide onto location that clip lug 12 is positioned at slide 2 cut 23 in slide 2;
Fig. 6 is middle rail 5 relative outer rails 4 small distances that stretch again, and its clip lug 12 promptly slips into cuts 23 and the location in the location of slide 2, collude part 3 then continuation be drawn out with middle rail 5;
Fig. 7 is the operation signal of rail 5 in ought folding once again, after middle rail 5 incomes, first hook 31 and second hook 32 that collude part 3 can be inserted in the draw-in groove 13 of slide block 1 once again, and lug 52 pushing and pressing slide blocks 1 with middle rail 5, make clip lug 12 can break away from the polarizing slot 23 of slide 2, and block 14 offsets and colludes part 3, reaches middle rail 5 and automatic homing and retract slide block 1 by first elastic parts 15.
Again, when operation has abnormal case to take place, promptly, when the clip lug 12 of slide block 1 is positioned at the operation failure of polarizing slot 23 of slide 2, for example external force vibrations make slide block 1 slide 2 rear ends of rebounding accidentally behind drawing process or location, as shown in Figs. 8 to 11, wherein Fig. 8 is the schematic diagram of location failure, slide block 1 with collude that part 3 separates and slide block 1 rebounds stowed position, for getting rid of this situation, as shown in Figure 9, can middle rail 5 be pushed back " also can after this pulls out use, push back again certainly/so this pushes back operation does not no doubt have the automatic homing start; just recover tool automatic homing function but pull out again next time ", collude part 3 deflectable functions by this, the block 14 that its first hook 31 arrives to slide block 1 is automatic deflection, again as shown in figure 10, first hook 31 that colludes part 3 can collude in the draw-in groove 13, then as shown in figure 11, pull out middle rail 5 and collude part 3, then first hook 31 catches on block 14, and then take slide block 1 again out of, can make the clip lug 12 of slide block 1 slip into again and finish the location, thereby remove the abnormal case of location failure in the polarizing slot 23 of slide 2.
As Figure 12 and shown in Figure 13, it is another embodiment of the present invention, and see also Fig. 1, it comprises slide block 1, slide 2, colludes part 3 and interior rail fixture 7, and collocation outer rail 4 " see Fig. 1, construct identical, so do not give unnecessary details " reach middle rail 5A and interior rail 6A and implement, because it is different that slide block 1, slide 2, structure and the enforcement aspect and the previous embodiment of colluding part 3 there is no, so do not give unnecessary details.Wherein, interior rail fixture 7 is articulated on the middle rail 5A, and interior rail fixture 7 can pass its secondary rail 51A swing, rail fixture 7 comprises at least more than one protruding the 71, the 3rd elastic parts 72 and the trunnion 73 of colluding in being somebody's turn to do, and interior rail fixture 7 is articulated in middle rail 5A with trunnion 73, interior rail 6A then correspondence is provided with fixed part 61A, and by the effect of the 3rd elastic parts 72, makes the protruding 71 fixed part 61A that can support inside rail 6A that collude.
And the operational scenario of rail fixture 5A mutually, as Figure 14 and shown in Figure 15, when folding, as shown in figure 14, do not fold fully as yet at interior rail 6A, the protruding fixed part 61A place of colluding rail 6A in 71 no shows still of interior rail fixture 7, when fixture 7 is displaced to fixed part 61A, as shown in figure 15, fixed part 61A interior the protruding of rail fixture 7 of jack-up automatically colludes 71, immediately, as shown in figure 16, interior rail fixture 7 is subjected to the effect of the 3rd elastic parts 72, it is protruding collude 71 reactivations block in the fixed part 61A of rail 6A, and in making rail 6A relatively in rail 5A be fixed in collapse state; Again, as shown in figure 17, the 3rd elastic parts 72A that interior rail fixture 7A is cooperated must be a kind of torque spring.
In addition, as shown in figure 18, the fixture of slide 2A one of can also the corresponding outer rail 4A of hook pin 26A fixture colludes groove 45A and affixed.
And, as Figure 19, Figure 20 and shown in Figure 21, be respectively other aspect implemented of colluding part 3A, 3B, 3C, wherein, as shown in figure 19, the second elastic parts 35A is a kind of elastic strip body; As shown in figure 20, the second elastic parts 35B is a kind of extension spring; As shown in figure 21, the second elastic parts 35C is a kind of torque spring.
Though 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 used for illustrating the present invention, under the situation that does not break away from spirit of the present invention, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of claims of the present invention in connotation scope of the present invention.
