Between the upper rail and the retaining rail, and it is located at the rear end of the middle rail；The counter weight construction is also articulated with and the fixation
Rail upper surface rolls the roller bearing of cooperation.
Further, the first roll wheel assembly is movably set between the upper rail and the middle rail；First roller group
Part includes the first turning rolls and the first idler wheel for being articulated on first turning rolls；First idler wheel respectively with the upper rail
Cooperation is rolled with the middle rail.
Further, the middle rail be formed with split with first turning rolls rear and front end, and be respectively used to it is described
First turning rolls offsets the first position limiting structure touched；The upper rail is formed with positioned at first turning rolls front end, and for
First turning rolls offsets the second position limiting structure touched；The counter weight construction is also used to offset with the rear end of the middle rail and touch.
Further, the second roll wheel assembly is movably set between the middle rail and the retaining rail；Second idler wheel
Component includes the second turning rolls and the second idler wheel for being articulated on second turning rolls；Second idler wheel respectively with it is described in
Rail and the retaining rail roll cooperation.
Further, the middle rail is formed with two third position limiting structures of second turning rolls rear and front end that is placed in,
The third position limiting structure is touched for offseting with second turning rolls；The retaining rail is formed with positioned at second turning rolls
The 4th preceding position limiting structure, the 4th position limiting structure are touched for offseting with second turning rolls.
Compared with prior art, the utility model has the beneficial effects that:
The utility model is prevented when upper rail stretches out excessive, the rear end of upper rail is upward by the way that counter weight construction is arranged in upper rail
Inclination, and cooperate roller bearing and retaining rail upper surface to roll and cooperate, at this point, retaining rail supports counter weight construction, and after avoiding upper rail
End tilts down, so that the relatively middle rail of upper rail keeps stablizing, reduces inclined amplitude, and ensure the three section guide rails of this Anti-inclining
Using smoothness, prolong the service life.

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
A kind of three section guide rails of Anti-inclining as shown in Figs 1-4, including upper rail 10, middle rail 20 and retaining rail 30；Middle rail 20
Rolling is mounted on retaining rail 30；The rolling of upper rail 10 is mounted on middle rail 20；The rear end of upper rail 10 is equipped with counter weight construction 40；Counterweight
Structure 40 is located at the rear end of middle rail 20 between upper rail 10 and retaining rail 30；Counter weight construction 40 is also articulated with and retaining rail
30 upper surfaces roll the roller bearing 50 of cooperation；In use, upper rail 10 moves forward, and when apart from more, counter weight construction 40 is acted on
In the rear end of upper rail 10, and roller bearing 50 and 30 upper surface of retaining rail roll and cooperate, and retaining rail 30 supports counter weight construction 40, and then keeps away
Exempt from the inclination of upper rail 10, it is ensured that the use smoothness of the three section guide rails of this Anti-inclining prolongs the service life.
Preferably, the first roll wheel assembly 60 is movably set between upper rail 10 and middle rail 20；First roll wheel assembly 60 includes
First turning rolls 61 and the first idler wheel 62 for being articulated on the first turning rolls 61；First idler wheel 62 respectively with upper rail 10 and middle rail 20
Cooperation is rolled, smooth degree is further increased.
Rail 20 in being detached from order to avoid 10 moving distance of upper rail is excessive is split and the it is highly preferred that middle rail 20 is formed with
One turning rolls, 61 rear and front end, and it is respectively used to the first position limiting structure 21 touched that offsets with the first turning rolls 61；The formation of upper rail 10
Have and be located at 61 front end of the first turning rolls, and for the second position limiting structure 11 touched that offsets with the first turning rolls 61；Pass through two first
Position limiting structure 21 avoids rail 20 in the disengaging of the first roll wheel assembly 60；Counter weight construction 40 and the cooperation of the second position limiting structure 11 avoid first
Roll wheel assembly 60 is detached from upper rail 10, that is, avoids rail 20 in the disengaging of upper rail 10.
Further, the second roll wheel assembly 70 is movably set between middle rail 20 and retaining rail 30；Second roll wheel assembly 70
The second idler wheel 72 turning rolls 71 and be articulated on the second turning rolls 71 including second；Second idler wheel 72 respectively with middle rail 20 and solid
Orbit determination 30 rolls cooperation, improves smooth degree.
In order to avoid middle rail 20 is moved through more and is detached from retaining rail 30, further, middle rail 20, which is formed with, is placed in the
Two third position limiting structures 22 of 71 rear and front end of second wheel frame, third position limiting structure 22 are touched for offseting with the second turning rolls 71；
Retaining rail 30 is formed with the 4th position limiting structure 31 before the second turning rolls 71, and the 4th position limiting structure 31 is used for and the second idler wheel
Frame 71, which offsets, to be touched；It avoids the second roll wheel assembly 70 from being detached from by two third position limiting structures 22, is being located at 71 rear end of the second turning rolls
Third position limiting structure 22 be butted on the second turning rolls 71, and when the second turning rolls 71 is butted on four position limiting structures 31, middle rail 20 is not
It can continue to move along, and then middle rail 20 is avoided to be detached from retaining rail 30；Furthermore two third position limiting structures 22 can avoid the second rolling
Wheel carrier 71 is detached from.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to
In the utility model range claimed.
