The specific embodiment

Further illustrate the utility model below in conjunction with drawings and Examples.

The utlity model has two kinds of structures of mirror image symmetry each other, they are separately fixed at drawer left front bottom end and the right-hand front bottom end of drawer and respectively near the movable rail front end of left and right two nest of drawers guide rails; The present embodiment is only described the right side structure.

Fig. 1 and Fig. 2 are structures of existing guide rail product, and it comprises fixed track 6, mid-rail 7 and movable rail 5.For coordinating of the present utility model installing and using, add a plastic tooth row 51 at the front end of movable rail 5, there are a plurality of vertical teeth tooth row 51 sides; The front end of movable rail 5 also installs a plastic glue 52 additional, and a slope 53 is arranged above a glue 52.

Referring to Fig. 3 and Fig. 4, the drawer positions adjusting device of the present embodiment comprises handle base 1, control fork 2, regulating wheel 3 and slide block 4, and handle base 1, control fork 2, regulating wheel 3 and slide block 4 are all made of plastic.

Referring to Fig. 5 and Fig. 6, handle base roughly is box-shaped, has front facade 11, rear facade 12 and neutral surface 13, and neutral surface 13 is divided into control fork storehouse 14 and slide block storehouse 15 with handle base; Axis hole 140 is arranged at 14 bottoms, control fork storehouse, and control fork storehouse 14 rear walls have square hole 141; There are 151, two slideways 151 of slideway of two band tooth bars 150 parallel to each other on the 15 both sides bulkheads of slide block storehouse; One has flexible pawl arm 16 and is connected to adjustment seat 1 rear wall end, and pawl arm 16 has handle 161 to be used for handling pawl arm;

There is one perpendicular to the first installing hole 130 of bottom surface on neutral surface 13, has two perpendicular to the second installing hole 110 of front facade 11 on front facade 11.

Referring to Figure 10 and Figure 11, control fork has the sliding part 21 that is ┗ ┙ tee section, and the interior exterior feature in the control fork storehouse of sliding part 21 and handle base is adaptive, on the rear wall 25 of sliding part 21, prong 22 is arranged, and the prong of prong 22 is wide adaptive with the thickness movable rail upstanding edge; Sliding part 21 bottoms have along prong 22 the widths long guide hole 23 that extends and the projection 24 that is positioned at long guide hole 23 tops.

Referring to Fig. 7 to Fig. 9, the involute guide groove 32 that there is central shaft 31 the regulating wheel bottom surface and launches around central shaft 31; The diameter of central shaft 31 is adaptive with the shaft hole diameter on handle base, and the width of involute guide groove 32 is adaptive with the diameter of the projection on control fork.There is tooth 33 to be convenient to stir with hand on the regulating wheel circumference.

Referring to Figure 12 and Figure 13, slide block has latch bolt 41, positioning tooth 42 and push pedal 43, and there are two sliding shoulders 44 at latch bolt 41 rear portions, and positioning tooth 42 is connected to latch bolt 41 front ends by elastic bridge 45; Two sliding shoulders 44 can be respectively with handle base on both sides, slide block storehouse bulkhead on two slideways contact, positioning tooth 42 can be simultaneously with both sides, slide block storehouse bulkhead on two tooth bars mesh; Elastic bridge 45 both sides are shaped with two buckles 46 and are used for slide block is arranged in the slide block storehouse.

During assembling, the square hole 141 of the prong 22 of control fork 2 from handle base 1 outwards passed, the control fork storehouse 14 that control fork 2 is placed into handle base 1 makes its sliding part 21 contact with 14 bottoms, control fork storehouse and two side, this moment control fork 2 long guide hole 23 namely with axis hole 140 perforations of handle base 1.The long guide hole 23 that the central shaft 31 of regulating wheel 3 is passed control fork 2 penetrates the axis hole 140 of handle base 1 again, and makes the projection 24 of control fork 2 insert involute guide groove 32.Slide block 4 is pressed into slide block storehouse 15, make two behinds that buckle 46 blocks two slideways 151 of slide block, at this moment two sliding shoulders 44 that are positioned at latch bolt 41 rear portions contact with two slideways 151 in slide block storehouse 15, and positioning tooth 42 and two tooth bars 150 mesh under the elastic force effect of elastic bridge 43.

Utilize the first installing hole 130 and the second installing hole 110 handle base 1 to be fixed on the bottom of the right-hand front end of drawer, the control fork storehouse 14 of handle base 1 and slide block storehouse 15 are all covered by drawer-bottom board, thereby control fork 2, regulating wheel 3 and slide block 4 all are limited in space in two storehouses.

In the time of above drawer is placed to movable rail, the rear end of drawer is welded in the buckle 54(of movable rail 5 afterbodys referring to Fig. 3) fasten, thus the ratchet 160 on pawl arm 16 fastens the drawer front end with tooth row 51 engagements that are arranged on movable rail 5 front ends under the elastic force effect; At this moment, the prong 22 that outwards passes from the square hole 141 of handle base 1 clamps the upstanding edge of movable rail 5, the latch bolt 41 of 15 slide blocks 4 that stretch out backward contacts with the slope 53 that is arranged on a glue 52 of movable rail 5 front ends from the slide block storehouse.

The utility model can carry out the adjustment of two frees degree:

1. when rotating regulating wheel 3, the projection 24 on the common guide adjustment fork 2 of involute guide groove 32 and long guide hole 23 moves left and right control fork 2; Because prong 22 forks of control fork 2 have been lived the upstanding edge of movable rail 5, so at this moment the drawer front end is done the left and right skew with respect to movable rail 5.

2. when pressing push pedal 45 from bottom to top, on positioning tooth 42 and handle base, 1 tooth bar 150 separates, thereby at this moment again before and after push-and-pull push pedal 45 can change latch bolt 41 and stretch out the length in slide block storehouse and change inclined-plane 47 length overlapping with the slope 53 on a glue 52 of latch bolt 41, and then the drawer front end is made the adjustment of rising height.

Only need apply pressure to the handle 161 of pawl arm 16 in the time of will separating drawer from drawer guideway, just can haul out drawer after ratchet 160 on pawl arm 16 is separated with the tooth row 51 of movable rail 5 front ends.
