Description
Technical field
The utility model relates to a kind of drawer guideway, is specifically related to a kind of improved drawer guideway.
Background technology
Guide rail in the drawer is generally two joint or three joints, and wherein, two joint guide rails comprise retaining rail and movable rail, and retaining rail is fixed on the sidewall of drawout cubicle, and movable rail is fixed on the drawer, and movable rail can slide in retaining rail, realizes the extraction of drawer and pushes back; Three joint guide rails then also are provided with middle rail between retaining rail and movable rail, wherein movable rail can slide at middle rail, and middle rail can slide in retaining rail.Referring to Fig. 1, a kind of two joint drawer guideways of the prior art have been shown among the figure, the cross section of retaining rail 1 is roughly L-shaped, and wherein vertical portion 11 is fixedly connected on the drawout cubicle, is extended with for the sliding part 13 that movable rail 2 is installed in a side direction relative with vertical portion 11 on the horizontal part 12; Described movable rail 2 is downward opening U-shaped and is placed on the sliding part 13 of retaining rail 1, wherein, between the end face of the inner top surface of movable rail 2 and sliding part 13 and between the side of the medial surface of movable rail 2 and sliding part 13 rolling element is set all, and, unsettled between the horizontal part 12 of the lower end of the two sides of movable rail 2 and retaining rail 1, therefore movable rail 2 and on the gravity of drawer mainly born by the rolling element between the end face of the inner top surface of movable rail 2 and sliding part 13, can there be so following two problems: 1, under the normality, if drawer and in-built object thereof are heavier, rolling element can deform because continue to bear larger gravity, and then the rolling characteristics of impact, increase resistance; Special in rolling element made of plastic, this situation of easier appearance; 2, drawer supports because the bottom of the two sides of movable rail 2 lacks extracting out or pushing back in the process, therefore can rock to both sides, causes movable rail to slide and has some setbacks.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiency that prior art exists, provide a kind of drawer is had preferably support, gravity that rolling element bears is little and drawer at the improved drawer guideway of extracting or push back motion steady and smooth in the process out.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of improved drawer guideway comprises that cross section is that L shaped retaining rail and cross section is the movable rail of U-shaped, and wherein, the horizontal part of retaining rail is extended with for the sliding part that movable rail is installed in a side direction relative with the vertical portion; Described movable rail is placed on the sliding part of retaining rail, is provided with rolling element between movable rail and the sliding part; It is characterized in that the side at the horizontal part that is positioned at retaining rail on the described movable rail is provided with the support wheel of normality lower support on this horizontal part.
A preferred version of the present utility model, wherein, described support wheel is arranged at the end of the outer end of movable rail; That is be positioned at towards an end of extracting or push back the operator of drawer out.Under the normality, this end is positioned on the horizontal part of retaining rail, and described support wheel has supporting role to movable rail.
A more preferred scheme of above-mentioned preferred version, the horizontal part of described retaining rail are provided with the skewed slot for the guide support wheel in the end with the support wheel corresponding end.The purpose that this skewed slot is set is: drawer is in the process that pushes back, and support wheel has a process of climbing up gradually when rolling on the horizontal part of retaining rail, prevent the impact of moment.
One of above-mentioned preferred version scheme more specifically, described support wheel is arranged on the bottom of a bracing frame, the top of this bracing frame is fixedly connected with movable rail, this syndeton is: described movable rail is respectively equipped with two side locating slots and an end face locating slot at side and the end face of a side of the horizontal part that is positioned at retaining rail, correspondingly be respectively equipped with two side locating pieces and an end face locating piece on the side of described bracing frame and the end face, described side locating piece and end face locating piece are embedded in respectively in corresponding the side locating slot and end face locating slot.
A scheme more specifically of the present utility model wherein, is provided with middle rail between described retaining rail and the movable rail; That is this drawer guideway is three joint rails.
The utility model compared with prior art has following technique effect:
Because the movable rail of drawer guideway of the present utility model is provided with the support wheel of normality lower support on this horizontal part in a side of the horizontal part that is positioned at retaining rail, therefore, under the normality, described support wheel provides a strong point, can bear the part gravity of drawer and in-built object thereof, thereby reduced the pressure to rolling element, rolling element can not deformed, kept its good rolling characteristics; Drawer is being extracted out or is being pushed back in the process, and described support wheel rolls and provides support at the horizontal part of movable rail, therefore greatly reduces the amplitude that movable rail rocks, so that the motion steady and smooth of movable rail.
