[detailed description of the invention]
For making object of the present invention, scheme and beneficial effect clearly understand, below in conjunction with accompanying drawing 1-5 and preferred embodiment, the invention will be further described.
To be described in detail exemplary embodiments of the present invention now, its example is shown in the drawings, and Reference numeral identical in all accompanying drawings represents identical original paper.Below embodiment will be described so that the present invention to be described by referring to accompanying drawing.
The present embodiment is for the refrigerator of two in refrigerating appliance, comprise superposed refrigerating chamber and the refrigerating chamber being positioned at bottom, drawer is provided with in refrigerating chamber, drawer level can pass in and out refrigerating chamber under the effect of guide assembly, guide assembly comprises the fixed guide being fixed on refrigerating chamber inner bag for a pair and the rail plate laying respectively at drawer both sides for a pair, and rail plate slides along fixed guide.Fig. 1 is the structural representation of guide assembly of the present invention, and Fig. 2 is the enlarged drawing of local P in Fig. 1.
The guide assembly shown in Fig. 1 is when drawer is drawn out refrigerating chamber to greatest extent, rail plate 10 and fixed guide 20 position each other.Fixed guide 20 having multiple first connecting portions 29 for being connected with refrigerating chamber inner bag, through the hole of the first connecting portion 29, fixed guide 20 being fixedly attached to the inner bag of refrigerating chamber by screw or buckle; Rail plate 10 is also provided with multiple second connecting portions 19 for being connected with drawer, second connecting portion 19 fixes with rail plate 10, drawer respectively, with make drawer stable be fixed on rail plate 10, for the ease of installation and removal, the second connecting portion 19 is all be connected with rail plate 10, drawer by the form of clamping.
Fixed guide 20 comprises fixed guide main body and the first roller 28, when drawer is drawn out refrigerating chamber to greatest extent, as shown in Figure 2, first roller 28 is fixed on the one end near refrigerating chamber opening in fixed guide main body, the cross section of fixed guide main body is roughly C shape, comprises the first slide plate 21, second slide plate 22 and the first linkage section 23 between the first slide plate 21 and the second slide plate 22; Rail plate 10 comprises rail plate main body and the second roller 18, when drawer is drawn out refrigerating chamber to greatest extent, second roller 18 is fixed on the one end near refrigerating chamber opening in rail plate main body, similar with fixed guide main body, the cross section of rail plate main body is also roughly C shape, comprises the 3rd slide plate 11, the 4th slide plate 12 and the second linkage section 13 between the 3rd slide plate 11 and the 4th slide plate 12.
First roller 28 is arranged between the 3rd slide plate 11 and the 4th slide plate 12, second roller 18 is arranged between the first slide plate 21 and the second slide plate 22, for the ease of the slip of the first roller 28 and the second roller 18, between the first roller 28 and the 3rd slide plate 11, the 4th slide plate 12 and between the second roller 18 and the first slide plate 21, second slide plate 22, and non-fully laminating, but there is certain gap.If there is error in manufacturing process, then likely this gap is amplified.
As shown in Figure 4 and Figure 5, Fig. 4 is the structural representation of the fixed guide local in Fig. 2, and Fig. 5 is the upward view of Fig. 4.One wear-resisting working of plastics 25 is set in one end of fixed guide 20, the structure of working of plastics 25 as shown in Figure 6, this working of plastics 25 is roughly similar to a clip, be coated and fixed the end of the second slide plate 22 of guide rail 20, insert the hole 24 of the second slide plate 22 additionally by the pawl 251,152 on clip and realize the fixing of working of plastics 25, working of plastics 25 is provided with two downward pawls 251 and a pawl 252 upwards.In the non-loaded situation of rail plate 10, have gap between the 4th slide plate 12 of rail plate 10 and working of plastics 25, rail plate 10 contacts working of plastics 25 hardly in the process of sliding, and does not have frictional force each other; When drawer is connected to rail plate 10, and in drawer during carrying weight, rail plate 10 can move down in vertical direction position, and the 4th slide plate 12 of rail plate 10 can be supported on working of plastics 25, and namely the sinking of limit slippage guide rail 10 at vertical direction is understood in the existence of working of plastics 25.Due to rail plate 10 sink time, first roller 28 and the pressure increase between the 3rd slide plate 11, second roller 18 and the first slide plate 21, the increase of frictional force during slip between directly causing, the loss of the first roller 28 and the second roller 18 is increased, reduce the life-span, therefore, working of plastics 25 supports the loss that rail plate 10 can reduce the first roller 28 and the second roller 18, increases the life-span of the first roller 28 and the second roller 18.In order to increase the wearability of working of plastics 25, the good material of anti-wear performance can be used to make, such as POM.
Although working of plastics 25 limits the sinking of rail plate 10, but between working of plastics 25 and rail plate 10, also adds additional frictional force, in order to reduce the friction between the 4th slide plate 12 of rail plate 10 and working of plastics 25, in another embodiment, can replace working of plastics 25 with trundle, the diameter of trundle is arranged to be substantially equal to the height towards first roller 28 of working of plastics 25 on the 4th slide plate 12.Replace sliding friction with rolling friction, when the pressure of contact surface is certain, frictional force can be reduced greatly.
Fig. 3 is the sectional view along Aa dotted line in Fig. 2, when drawer is drawn out refrigerating chamber to greatest extent, the second slide plate 22 being positioned at the rail plate 10 immediately below the second roller 18 on rail plate 10 also has the projection 27 towards the second roller 18 formed by groove 26, the groove 26 that this projection 27 is formed by the outside at the second slide plate 22 and producing, the height of protruding 27 is advisable with 50% to 90% of the gap between the second roller 18 and the first slide plate 21, second slide plate 22.Same projection 27 also can be arranged on the first slide plate 21 directly over the second roller 18, its object is all the moveable spaces in order to limit the vertical direction of the second roller 18 between the first slide plate 21, second slide plate 22, thus reduce the relative motion at vertical direction of rail plate 10 and fixed guide 20, and then reduce the sinking of rail plate 10.Second slide plate 22 holds the hole 31 of the pawl 251,252 of working of plastics 25 and visible Fig. 5 of relative position of groove 26.
When drawer is drawn out refrigerating chamber to greatest extent, 4th slide plate 12 of the fixed guide 20 immediately below the first roller 28 has towards the projection of the first roller 28, the groove that this projection is formed by the outside at the 4th slide plate 12 and producing, when drawer is drawn out refrigerating chamber to greatest extent, due to the existence of projection, decrease the first roller 28 moveable space of vertical direction between the 3rd slide plate 11, the 4th slide plate 12, therefore, the object that limit slippage guide rail 10 sinks can be played.In addition, also can be positioned at convex to form in position directly over the first roller 28 at the 4th slide plate 12, generation type and the 3rd slide plate 11 similar.
