Abstract
The utility model relates to the technical field of rolling, sliding and supporting of tracks, in particular to a drawer opening-and-closing device. The drawer opening-and-closing device comprises a drawer, idler wheels and the tracks. The drawer opening-and-closing device is characterized in that each track is provided with a linear segment and a big cross section segment, fixed idler wheels are arranged at big cross section ends of the tracks, racks and sliding channels are arranged in the tracks, and the drawer is provided with lower sliding channels. Gears and the idler wheels are fixedly connected and respectively connected with the racks and the sliding channels in a rolling mode, and the gears and the idler wheels are connected with a speed reduction transmission device through transmission shafts. The speed reduction transmission device is fixedly connected with the drawer, the sliding channels of the drawer are in sliding connection with the fixed idler wheels of the tracks, and the rear end of the drawer conducts similar linear motion along the tracks. The big cross sections of the tracks enable the drawer to be in a downwards-inclined motion trajectory in the slipping-off process, and the speed reduction transmission device enables the drawer to conduct self locking in the motion process. When a self-locking type downwards-turning drawer is folded, the drawer is fixed at the high position, when the drawer is unfolded, the drawer is kept at the low position, and a user can conveniently conduct storing-and-taking operation on appliances in the drawer.
Description
Technical field
The utility model relates to track sliding support technical field, a kind of drawer closing device specifically, drawer was fixed on the higher position when this drawer closing device was packed up, and remained on lower position and self-locking during expansion, conveniently object in the drawer was carried out accessing operation.
Background technology
At present, existing special purpose vehicle all is provided with the equipment case of storing utensil, and the equipment case is divided into opening door, drawer type etc., and the characteristics of opening door equipment case are that the space is big in the case, and accommodation tool is many, and its deficiency is the utensil access inconvenience of the inside, the not convenient usefulness of depth space; The characteristics of drawer type equipment case are that the utensil access is convenient, and depth space is beneficial to use, and its deficiency is: one, upper strata drawer equipment case position is higher, and the utensil access is effort; Two, manually pull folding position is wayward.
Owing to have above-mentioned deficiency on the existing weaponry and equipment box technology, use inconvenience.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, when being provided, a kind of packing up be fixed on the higher position, remain on lower position during expansion, skid off and present downward-sloping movement locus in the process, speed reduction gearing can make drawer self-locking in motion process, the convenient self-locking drawer closing device that utensil in the drawer is carried out access.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of drawer closing device, comprise drawer, roller and track, be characterised in that track is provided with straightway and heavy in section section, track heavy in section end is provided with fixed idler whell, is provided with tooth bar and slideway in the track, and drawer is provided with glide path, gear is fixedly connected with roller and rolling is connected with slideway with tooth bar respectively, gear is connected with speed reduction gearing through power transmission shaft with roller, and speed reduction gearing is fixedlyed connected with drawer, and drawer runner and track fixed idler whell are slidingly connected.
Track and fixed idler whell symmetry, fixedly install.Tooth bar and slideway are oppositely arranged.Gear diameter is less than roller diameter.Speed reduction gearing is reducer of turbodrill, is located at the drawer bottom.Gear and roller are symmetrically set in about drawer.The speed reduction gearing input is connected with handwheel or motor.
The beneficial effects of the utility model are that when the drawer closing device was packed up, drawer was fixed on the higher position, remain on lower position during expansion, skid off and present downward-sloping movement locus in the process, convenient utensil in the drawer is carried out access, speed reduction gearing can make drawer self-locking in motion process.
Description of drawings

Fig. 2 is the utility model transmission device schematic diagram.
Fig. 3, Fig. 4 are the utility model partial schematic diagrams.
Reference numeral: 1, handwheel; 2, track; 3, drawer; 4, track; 5, worm reducer; 6, roller; 7, gear; 8, tooth bar; 9, fixed idler whell; 10, universal joint; 11, power transmission shaft; 12, universal joint; 13, power transmission shaft; 14, power transmission shaft; 15, tooth bar; 16, gear; 17, roller; 18, fixed idler whell.
The specific embodiment:
The present invention is further described below in conjunction with accompanying drawing:
As accompanying drawing 1, accompanying drawing 2, Fig. 3, shown in Figure 4, a kind of drawer closing device, comprise drawer 3, roller 6, roller 9, roller 17, roller 18, also comprise track 2, track 4, track 2,4 are provided with straightway and heavy in section section, track heavy in section end is provided with, be provided with tooth bar 8 in the track, tooth bar 15 and slideway, drawer 3 is provided with glide path, gear 7, gear 16 and roller 6, roller 17 fixedly connected and respectively with tooth bar 8, tooth bar 15 rolls with slideway and is connected, gear and roller are through power transmission shaft 13,14 are connected with worm reducer 5, and worm reducer 5 is fixedlyed connected with drawer 3, the glide path of drawer 3 and track fixed idler whell 9, fixed idler whell 18 is slidingly connected.
The kind of drive of drive unit is: handwheel 1 rotates, drive power transmission shaft 11 by universal joint 10, power transmission shaft 11 drives worm reducer 5 by universal joint 12, worm reducer 5 drives the gear 7,16 of drawer both sides by left and right sides power transmission shaft 13,14 usefulness keys, the tooth bar 8,15 of gear 7,16 in left and right sides track 4,2 rotates, and rectilinear motion is done along track in the rear end that drives drawer 3.And the groove of drawer 3 left and right sides slides at the roller 9 of left and right sides track 4,2 front ends, 18, makes drawer present downward-sloping movement locus in the process of skidding off. Roller 6,17 freely rotates on power transmission shaft 13,14, and its effect is that the lower surface in track 4,2 inboards rolls, and Support Gear does not break away from tooth bar.Because transmission device is to be undertaken by worm decelerating machine, can be self-locking in the optional position in motion process.
The beneficial effects of the utility model are that when the drawer closing device was packed up, drawer was fixed on the higher position, remain on lower position during expansion, skid off and present downward-sloping movement locus in the process, convenient utensil in the drawer is carried out access, speed reduction gearing can make drawer self-locking in motion process.
