Abstract
The utility model discloses an expansion three-section guide rail, comprising a first return board part, a second return board part and a middle return board part; wherein the first return board part and the second return board part are slideable connected with the middle return board part through a plurality of upper ball bearings and lower ball bearings; the middle return board part comprises an upper return board part and a lower return board part with outside side way which are fixedly connected with each other via a support tube; the first return board part and the second return board part are separately provided with a inner slide way; the upper ball bearings and the lower ball bearings are respectively embedded between the inner slide way of the first and the second return board parts and the outside slide way of the upper and lower return board parts. The utility model has the advantages that: the support tube can increase the thickness of the entire guide rail and correspondingly increase the rigidity of the guide rail, even when stretched completely the guide rail also can withstand the heavier load, the manufacture craft is simple, the upper return board and the lower return board of the middle return board part are gained through the manufacture craft of the common two-section guide way, and then are fixedly connected through the support tube.
Description
Technical field
The utility model relates to a kind of guide rail.Especially a kind of guide rail that is used on drawer, the cabinet.
Background technology
Guide rail is commonly used to drawer, tray and rack mount type equipment telescopically are connected on the structures such as cabinet, frame.At present, this guide rail mainly adopts the more of two-part, can adopt the guide rail of syllogic certainly under the situation of the sliding distance of needs.China Patent No. is the slim drawer sliding rail of the three-member type of CN02803304.3, a kind of guide rail of syllogic is disclosed, this guide rail comprises outer skateboard part, middle skateboard part and inner slider parts, outer skateboard part is provided with inboard slideway, middle skateboard part is provided with inboard and outside slideway, and the inner slider parts only are provided with outside slideway, middle skateboard part by placing outer skateboard part inboard slideway and the ball bearing between the outside slideway of middle skateboard part slidably be embedded in the outer skateboard part, the same inner slider parts also ball bearing between the outside slideway of the inboard slideway by skateboard part in the middle of placing and inner slider parts slidably are embedded in the outer skateboard part, this structure is the thickness of whole guide rail of attenuate effectively, but also bring certain problem, rigidity as guide rail is less, especially after three sections skateboard parts stretch fully, whole guide rail becomes very soft, is easy to generate distortion.Because middle skateboard part will link to each other with two groups of ball bearings respectively, be provided with inboard and outside slideway in addition, therefore need form comparatively complicated section configuration, processing technology complexity the bending distortion that middle skateboard part carries out repeatedly.
Summary of the invention
The purpose of this utility model is to provide a kind of telescopic three joint guide rails, has increased the rigidity of guide rail, can bear heavier load, and manufacturing process is simple simultaneously.
The utility model is to realize above-mentioned purpose like this:
Telescopic three joint guide rails, comprise first skateboard part, second skateboard part and middle skateboard part, first skateboard part and second skateboard part slidably are connected with middle skateboard part by upper and lower ball bearing respectively, it is characterized in that described middle skateboard part comprises the upper and lower skateboard part that has outside slideway, upper and lower skateboard part is fixedly connected by stay pipe; First skateboard part and second skateboard part are respectively equipped with inboard slideway, and upper and lower ball bearing is embedded in respectively between the outside slideway of the inboard slideway of first skateboard part and second skateboard part and upper and lower skateboard part.
The beneficial effects of the utility model are: be provided with stay pipe between the upper and lower skateboard part of middle skateboard part, can increase the thickness of whole guide rail, also increased the rigidity of guide rail accordingly, even guide rail still can bear heavier load after the expansion that stretches fully, also very simple on manufacturing process, the upper and lower slide plate of skateboard part gets final product upper and lower slide plate then in the middle of can obtaining according to the manufacturing process of common two-part guide rail by stay pipe is fixedly connected.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a broken away view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, telescopic three joint guide rails comprise first skateboard part 1, second skateboard part 3 and middle skateboard part 2.Skateboard part 2 comprises the upper and lower slide plate 21,22 that has outside slideway 23,24 in the middle of described, and upper and lower slide plate 21,22 is fixedly connected by stay pipe 6; First skateboard part 1 and second skateboard part 3 are respectively equipped with inboard slideway 11,31, and upper and lower ball bearing 4,5 is embedded in respectively between the outside slideway 23,24 of the inboard slideway 11,31 of first skateboard part 1 and second skateboard part 3 and upper and lower skateboard part 21,22.Because stay pipe 6 can increase the thickness of whole guide rail, also increased the rigidity of guide rail accordingly, even guide rail still can bear heavier load after the expansion that stretches fully, also be that branch is simple on manufacturing process, the upper and lower slide plate 21,22 of skateboard part passes through stay pipe 6 fixedly connected getting final product with upper and lower slide plate 21,22 then between can obtaining according to the manufacturing process of common two-part guide rail.
In order to limit the sliding stroke that each skateboard part stretches, the web 25 of described upper and lower slide plate 21,22 is provided with clamp 26, and the end at first skateboard part 1 and second skateboard part 3 is fixed with locating part 27 accordingly.Collide when clamp 26 and locating part 27 and to make that skateboard part can not continue to stretch.The front and back position of setting clamp 26 as required just can limit the length that guide rail stretches fully and launches.
The upper and lower slide plate 21,22 of first skateboard part 1, second skateboard part 3, middle skateboard part 2, the other end of each parts also is provided with the baffle plate vertical with the web of corresponding component 7, when guide rail shrank, each skateboard part was collided with corresponding baffle plate 7 and can be stopped to slide.
In addition, first skateboard part 1 and/or second skateboard part, 3 bottoms are fixed with connecting plate 8, are convenient to guide rail and fixedly connected with drawer, cabinet etc.
Claims (4)
1. telescopic three joint guide rails, comprise first skateboard part, second skateboard part and middle skateboard part, first skateboard part and second skateboard part slidably are connected with middle skateboard part by upper and lower ball bearing respectively, it is characterized in that described middle skateboard part comprises the upper and lower slide plate that has outside slideway, upper and lower slide plate is fixedly connected by stay pipe; First skateboard part and second skateboard part are respectively equipped with inboard slideway, and upper and lower ball bearing is embedded in respectively between the outside slideway of the inboard slideway of first skateboard part and second skateboard part and upper and lower skateboard part.
