Embodiment 1
As shown in Figure 1-3, the present embodiment provides a kind of drawer backing guide rail structure, including upper conducting bar 1, lower conducting bar 2 and set
The slide assemblies 3 between upper conducting bar 1 and lower conducting bar 2 are set, upper conducting bar 1 can descend conducting bar 2 along its length by slide assemblies 3 relatively
Direction (i.e. front-rear direction) sliding.Above-mentioned slide assemblies 3 include retainer 30, ball 31 and roller 32, the two of retainer 30
Side wall offers multiple ball resettlement grooves 301, and the ball resettlement groove 301 of the every one side wall of retainer 30 is along the length of lower conducting bar 2
Degree direction is arranged, and the quantity of ball 31 is corresponding with the quantity of ball resettlement groove 301, and ball 31 is respectively placed in ball resettlement groove
In 301；The roof of retainer 30 offers multiple roller resettlement grooves 302, length of all roller resettlement grooves 302 along lower conducting bar 2
Degree direction is arranged, and the quantity of roller 32 is corresponding with the quantity of roller resettlement groove 302, and roller 32 is respectively placed in roller resettlement groove
In 302 and 32 both ends of roller are connect with 302 left and right sidewall shaft of roller resettlement groove, and roller 32 is in roller resettlement groove 302 around rolling
32 axis rotation of column guarantees the mounting stability of roller 32.By the way that ball resettlement groove 301 and roller placement is arranged in retainer 30
Slot 302 will not generate interference so that ball 31, roller 32 roll in respective resettlement groove between each other, guarantee ball
31, the smoothness that roller 32 rolls, avoids the occurrence of stuck.And retainer 30 is buckled in the lateral wall of lower conducting bar 2, upper conducting bar 1 is placed on
Lower 2 outside of conducting bar, retainer 30 are sandwiched between conducting bar 1 and lower conducting bar 2, and roller 32 is located at the top of upper conducting bar 1 and lower conducting bar 2
Contacted between wall and respectively with the roof of upper conducting bar 1 and lower conducting bar 2, ball 31 be located at upper conducting bar 1 and lower conducting bar 2 side wall it
Between and contacted respectively with the side wall of upper conducting bar 1 and lower conducting bar 2 so that upper conducting bar 1 is with the roof of lower conducting bar 2 and two sidewalls
Rolling friction, frictional force is small, slides smooth.
As a preferred solution, the ball resettlement groove 301 of above-mentioned 30 two sidewalls of retainer is symmetrical, so that
The ball 31 that must be placed in 30 two sidewalls ball resettlement groove 301 of retainer is also arranged symmetrically, and upper conducting bar 1 and lower conducting bar 2
Two sidewalls shape be also be symmetrical structure.The corresponding face contacted with ball 31 of the side wall of upper conducting bar 1 and lower conducting bar 2 is and ball
The globoidal structure of 31 cooperations, and the distance between two symmetrical balls 31 are less than the width of lower 2 roof of conducting bar, avoid ball
31 deviate from between upper conducting bar 1 and lower conducting bar 2, and but also the freedom degree of upper conducting bar 1 and about 2 lower conducting bar and left and right directions is complete
It is limited entirely, but is not influenced the freedom degree that conducting bar 1 and lower conducting bar 2 slide back and forth, effectively reduce pendulum of the conducting bar in sliding
Momentum improves the structural stability of guide rail.
In the present embodiment, the slide assemblies 3 between upper conducting bar 1 and lower conducting bar 2 are two, and double slide assemblies 3 are along lower conducting bar 2
Length direction arranged, double slide assemblies 3 are not connected to and separated by a distance each other, so that before upper conducting bar 1 and lower conducting bar 2
Back segment supports dynamic balance, and double slide assemblies 3 of the separate type are applicable in the guide rail of larger sliding distance.
Roller 32 is arranged by the roof in retainer 30 in the guide rail structure of the present embodiment, and ball is respectively set in two sidewalls
31, roof roller 32, two sidewalls ball 31, which are equivalent to, constitutes positive triangle mechanism, so that upper conducting bar 1 and about 2 lower conducting bar and left and right
The freedom degree in direction is limited completely, so that upper conducting bar 1 and lower conducting bar 2 opposite can only slide back and forth, therefore is reduced conducting bar and is existed
Oscillating quantity in sliding, improves the structural stability of guide rail, and the roller 32 of the roof of retainer 30, almost bears and acts on
All vertical forces on upper conducting bar 1 reduce influence of the vertical force to ball 31, therefore improve the stress intensity of conducting bar 1,
To improve the bearing of guide rail, and it is entirely separation between upper conducting bar 1 and lower conducting bar 2, is only produced with ball 31, roller 32
Raw rolling friction, frictional force is small, and upper conducting bar 1 and the opposite sliding of lower conducting bar 2 are more smooth.
Embodiment 2
The present embodiment and the drawer backing guide rail structure of embodiment 1 be it is similar, difference be adjacent slide assemblies 3 by
Separate type becomes Contiuum type, and as shown in Figs. 4-6, the slide assemblies 3 of the present embodiment are similarly two, but two slide assemblies 3
Retainer 30 linked into an integrated entity by connecting rod 4, double slide assemblies 3 of this integral structure, suitable for compact guide rail, conducting bar
Opposite sliding distance it is relatively small, but the guide rail of double slide assemblies 3 using the integral structure, structural stability is opposite to divide
From will get well.
Above-described the embodiments of the present invention does not constitute the restriction to scope of protection of the utility model.Appoint
It is practical new to should be included in this for modifications, equivalent substitutions and improvements etc. made by where within the spiritual principles of the utility model
Within the claims of type.
