Description

Door cabinet push-and-pull rail device

The utility model is about a kind of cabinet push-and-pull rail device.

See also shown in Fig. 9 A-B, the aluminium door body of commonly using 40 respectively is provided with a pulley 50 in its two in doorframe 41 lower edge faces, so that user's sliding opens and closes aluminium door body 40, and this pulley 50 is to be cross-placed on the fin 60 on ground.Yet, commonly use the installing configuration mode like this of structure, easily make the different users produce in various degree puzzlement.Wherein, higher as if user's height, the custom of opening the door that it is common is directly to carry out sliding to open aluminium door body 40 in handle 42 tops, thus, just makes this aluminium door body 40 promote to break away to take turns 50 perks and be difficult to and promotes (please cooperate and consult shown in Fig. 9 A); And if user's height is shorter, its custom of opening the door is directly carried out sliding mostly and is opened aluminium door body 40 in handle 42 belows, and makes a sideslip wheel 50 perks of this aluminium door body 40 be difficult to promote to open.Above-mentioned two kinds unlatching door body mode all has common shortcoming, very easily because of user's excessive sliding, causes this body that the danger of derailing is arranged, and is positioned on this fin 60 very inconvenience in the use and be difficult to install again.Therefore, produce the shortcoming of wheel body perk when commonly using the structure sliding, another structure is as shown in figure 10 just arranged, it is directly upper and lower two apical margins, 71 contacts of track 70 to be contacted with on the pulley 80, and can be just like commonly using the crooked situation of opening or derailing of being difficult to of door body as the former when making user's sliding.Yet, because of this pulley 80 is that contact is contacted with on upper and lower two apical margins 71 of track 70, and because of the active force of open and close door body on pulley 80, generation makes the user need expend strength and just is able to sliding frictional force, and because of long-time hair, foreign material or dust accretions on track 70, more make frictional resistance improve greatly, and make Men Tigeng be difficult to promote.Therefore, because above-mentioned various shortcoming has the necessity that is further improved really.

Thus, the purpose of this utility model is to provide a kind of cabinet push-and-pull rail device, and its constituent components is simple, the integral construction assembly is simple and easy, and when the open and close door body, frictional resistance is less, and sliding easily, and can avoid the crooked situation of opening or derailing of being difficult to of generator gate body.

The technical solution of the utility model is to provide a kind of cabinet push-and-pull rail device, includes track, and this rail top face is provided with a profile groove, and the inner upper and lower side of track is convexly equipped with out the contact edge in addition, and the door body of most the pulleys that are pivoted is installed on the track; It is characterized in that: the axis of the arbitrary limit of this body pulley is located on the differing heights, wherein has at least a pulley to be positioned contact edge on the track, and has at least another pulley to be positioned the following contact edge of track.

Described door cabinet push-and-pull rail device, it is characterized in that: this track is to be the aluminium extruded type framework.

Described door cabinet push-and-pull rail device, it is characterized in that: this track is a single track.

Described door cabinet push-and-pull rail device, it is characterized in that: this track is a double track.

Described door cabinet push-and-pull rail device is characterized in that: this track be provided with for a holder plug the location holddown groove.

The utlity model has following advantage:

1, the splendid labor-saving effect of tool: because each pulley on the Extendible flake of door body is located on the differing heights, make a pulley wherein can be positioned the last contact edge of track, another pulley can be positioned the following contact edge of track, and can make this pulley can be effectively with sliding the time the frictional force differentiation or subdue, and have splendid labor-saving effect when making sliding door body.

2, integral body can reach the result of use of smooth and easy sliding: held respectively by pulley on the upper and lower contact edge that is contacted with track, can avoid height and position difference because of user's sliding open and close door body, askew being difficult to of generator gate body opens or the derailing situation, and integral body can reach the smooth and easy sliding use effect of taking.

In sum, door cabinet push-and-pull rail device of the present utility model, its whole element constitutes simple, the construction assembly is simple and easy, and can push open easily or the door close body, the frictional force during effectively with sliding is broken up or is subdued, and has splendid labor-saving effect, do not have the crooked situation that is difficult to open or derails of a body and take place, have practicality.

For the utility model there being further understanding, below cooperate preferred embodiment and accompanying drawing, the effect that the utility model is reached describes in detail as the back:
