CN2546589Y - Single-row roller guide rail for self-balancing keeper - Google Patents

Abstract

The utility model belongs to the architectural material field, relating to a single-row ball bearing guide rail provided with self-balancing maintainers. The utility model comprises a fixed rail, a movable rail, ball bearings and maintainers; wherein the ball bearings are symmetrically arranged with a certain distance between every two among the self-balancing maintainers. Because the plurality of ball bearings are stressed simultaneously, the load is separately beared by the plurality of points, the ball bearings are ensured not to incline clockwise or counterclockwise and are avoided to rub with the upper and the lower guide rails, and the stabilization of the maintainer in self balancing for level state, thereby the guide rail is ensured to be stressed evenly. The utility model which has simple structure, large carrying capacity, good balancing and flexible operation is applicable for use as the commercial gate, the council chamber door, the dining room door, the hospital operating room door, the care unit door and the house living room door.

Description

The single-row spherical guide of self-balancing type retainer

Technical field

The utility model belongs to building material field, relates to a kind of single-row spherical guide that is provided with the self-balancing type retainer.

Background technology

Its operating principle of existing spherical guide is the pure rolling that goes up lower guideway and ball as shown in Figure 1, does not have the frictional dissipation of common bearing, so move brisk.General spherical guide is a double column structure, constitute by fixed track 1, movable rail 2, ball 3, retainer 4 etc., as arrange about among Fig. 2 or Fig. 3 in be arranged above and below, exist complex structure, bear pressure little wait not enough.Spherical guide among Fig. 4 has only two big balls 3, does not have retainer, adopts block 5, though structure is simple, has 2 deficiencies, one is that two balls all are rolled into on one side, another side does not have ball bearing, and balance is bad, so the drawback that lower guideway blocks can occur.The 2nd, can not all pure rolling in total travel, ball is gone to two ends and can only be slided in the original place.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and stressed even, balance is good, the single-row spherical guide of the self-balancing type retainer of flexible operation.

The technical solution adopted in the utility model: a kind of single-row spherical guide of self-balancing type retainer, comprise fixed track, movable rail, ball, retainer, it is characterized in that each ball by the certain distance symmetric arrays between the self-balancing type retainer.The self-balancing type retainer comprises slice, time sheet, and sheet is riveted together under retainer last slice and the retainer.Movable rail connects firmly below by bolt, boatswain chair and door leaf.

The utility model utilizes each ball when rolling, form center of rotation with horizontal direction, form different speed at the circular arc each point, a plurality of balls are arranged between the retainer by the certain distance bilateral symmetry,, make the each point load sharing because a plurality of balls bear pressure simultaneously, can be to tilting clockwise or counterclockwise, avoid and rail friction up and down, play the stabilization of retainer self-balancing maintenance level, make guide rail stressed evenly.The utility model is simple in structure, and supporting capacity is big, and balance is good, and flexible operation is suitable for commercial gate, conference room door, dining room door, hospital operating room door, ICU door, dwelling house parlor door etc. and is extensive use of.

The specific embodiment

Consult Fig. 5, shown in Figure 6, the single-row spherical guide of self-balancing type retainer mainly is made of sheet 402, rivet 9 etc. under fixed track 1, movable rail 2, ball 3, retainer 4, block 5, door leaf 6, bolt 7, boatswain chair 8, retainer last slice 401, the retainer, its fixed track 1 is fixed with building, be provided with ball 3 between fixed track 1 and the movable rail 2, a plurality of balls 3 are arranged between the self-balancing type retainer 4 by the certain distance bilateral symmetry, retainer 4 comprises slice, time sheet, and sheet 402 is riveted together by rivet 9 under retainer last slice 401 and the retainer; Movable rail 2 connects firmly with door leaf 6 below by bolt 7, boatswain chair 8.

Claims (3)

1. the single-row spherical guide of a self-balancing type retainer comprises fixed track, movable rail, ball, retainer, it is characterized in that each ball (3) presses the certain distance symmetric arrays between self-balancing type retainer (4).

2. the single-row spherical guide of self-balancing type retainer according to claim 1 is characterized in that self-balancing type retainer (4) comprises slice, time sheet, and sheet (402) is riveted together under retainer last slice (401) and the retainer.

3. the single-row spherical guide of self-balancing type retainer according to claim 1 is characterized in that movable rail (2) connects firmly with door leaf (6) below by bolt (7), boatswain chair (8).
