The specific embodiment
The structural representation that the utility model guide rail and roller cooperated when Fig. 2 closed fully for drawer, as shown in the figure, guide rail 9 is fixed on the inboard of refrigerator body 1, not end at guide rail 9 also is fixed with roller 8, fixing the dowel 3 that has positive stop 6 on the drawer 2, roller 8 contacts with the lower surface of dowel 3. and the front end of drawer is fixed with roller 7, roller 7 is embedded in the direction recess 10 of guide rail 9, on direction recess 10, following spigot surface cooperates, roller 7 up and down displacement in direction recess 10 is good to be no more than 2.5mm, the wherein said spigot surface 4 of going up is not held high inclined plane for front end is low, one section of following spigot surface front end does not hold one section to be gradient ramp section 5.1 for straightway 5.2, tangent position C between straightway 5.2 and the gradient ramp section 5.1 is when drawer 2 centers of gravity just in time drop on the roller 8, is fixed on the position at roller 7 and place, following spigot surface point of contact on the drawer 2.When drawer was closed fully, roller 7 only was contacted with strong point A1 with following spigot surface straightway 5.2.The structural representation that the utility model guide rail and roller cooperated when Fig. 3 was pulled to outermost end for drawer, as shown in Figure 3, when drawer is opened fully, positive stop 6 on the dowel 3 is stuck on the roller 8, prevent to cause the drawer landing because of overexerting, this moment, roller 7 only was contacted with strong point A2 with last spigot surface 4.
In the process of switch drawer, as shown in Figure 4 and Figure 5, when the center of gravity G of drawer was positioned at the left side of guide rail upper roller 6 strong points, roller 7 only was contacted with strong point B1 with last spigot surface 4; When the center of gravity G of drawer was positioned at the right side of guide rail upper roller 6 strong points, roller 7 only was contacted with strong point B2 with following spigot surface straightway 5.2.Because the last spigot surface 4 of guide rail 9 is not held high inclined plane for front end is low, following spigot surface 5.1 and 5.2 is a composite surface, when closing drawer, roller 7 spigot surface on the edge can not produce certain inertia by holding in the forward end sliding process, can well help drawer to automatically reset.When being pulled outwardly drawer, in case roller 7 arrives C point left side, any contact will can not take place with following spigot surface in roller 7 again, in the whole process, because the gap between spigot surface is comparatively loose, roller only contacts with one-sided spigot surface, can effectively slow down the wearing and tearing of roller.
Drawer is fully analyzed and studied to the utility model in the push-and-pull process, the motion track of its center of gravity, spigot surface up and down at guide rail is provided with curved surface, mix rational roller position again, because last spigot surface is the inclined-plane, drawer is in the process that pushes inward, giving certain power drawer will automatically reset, following spigot surface is provided with a gradient ramp, gap between the guide rail spigot surface is looser, in the process that drawer is extracted out, when the center of gravity of drawer has been crossed guide rail upper roller strong point position, the drawer upper roller just supports on the spigot surface, and when center of gravity had been crossed guide rail upper roller strong point position, following spigot surface just played a supportive role in the process that pushes inward, roller is in the push-and-pull process of drawer like this, both played basic support slip effect, also avoided simultaneously and spigot surface between unnecessary contact, effectively reduced the wearing and tearing of roller and guide rail.This combining form, because rolling wheel wear is light and avoided between the conventional guide rails spigot surface gap little, roller easily comes in contact and collides with non-support guide face in sliding process, so the slip ability is strong in the push-and-pull process, noise is little.
