Description

Heavy hidden rail with synchronization function

Technical Field

The utility model relates to a hide the technical field of rail, a heavy rail of hiding with synchronizing function specifically says so.

Background

The slide rail includes upper rail, well rail, lower rail, sliding connection has ball or roller between well rail and upper rail, the lower rail respectively. When the drawer moves, rolling friction exists between the sliding rails, and the drawer is simple in structure and labor-saving. However, when the slide rail with a large load is used, the precision and the assembly means of the upper rail, the middle rail and the lower rail are different, so that the rolling friction force between the rails is not uniform, the opening and closing sequence between the slide rails is uncertain, the pulling resistance on the left side and the right side of the drawer is influenced, and the using effect of the drawer is reduced.

Therefore, in the existing slide rail, a gear is installed on a middle rail, racks are respectively arranged on an upper rail and a lower rail, and when the slide rail is opened and closed, the gear can be meshed on the racks, so that the slide rail moves synchronously. However, the meshing clearance between the gear and the rack can generate vibration during operation, the service life is long, and the gear and the rack can be separated or even locked, so that the use of the drawer is also influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a heavy hidden rail with synchronizing function, its structure is firm, realizes synchronous motion between rail and the rail, and increases frictional force, avoids preventing that the gyro wheel from skidding, promotes the operating stability, and the quality of use of product is guaranteed in the production of noise reduction again.

The invention aims to realize the following steps: the utility model provides a heavy hidden rail with synchronizing function, includes sliding connection's last rail, well rail, lower rail in proper order, the ball nest subassembly is equipped with in the difference cunning between being connected of well rail and last rail, lower rail, wherein, synchronous gyro wheel is installed to well rail, last rail and lower rail are equipped with the annular knurl of being connected with synchronous gyro wheel dynamic friction respectively, and the annular knurl distributes respectively on the outer terminal surface of last rail, lower rail.

Optimizing according to the aforesaid, the middle part of well rail is equipped with the groove position, the location axle is installed to the groove position, and synchronous gyro wheel is installed on the location axle.

Optimizing according to the above, the middle part of the middle rail is provided with a convex reinforcing position protruding outwards.

According to the optimization, the knurls are respectively arranged at the outer corner positions on the left and right sides of the opening end of the upper rail and the outer corner positions on the left and right sides of the opening end of the lower rail.

According to the optimization, the knurls are designed into straight-line knurls.

Or the knurls are twill.

Or the knurls are designed into reticulate patterns.

The utility model has the advantages that: through the structure cooperation of synchronous gyro wheel and annular knurl, make rail, well rail, lower rail synchronous motion during opening and shutting, and increase frictional force avoids preventing that the gyro wheel from skidding, promotes the operating stability, and the quality of use of product is guaranteed in the production of noise reduction again.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

According to fig. 1 to 2 show, the utility model discloses a heavy hidden rail with synchronizing function, it includes sliding connection's upper rail 1, well rail 2, lower rail 3 in proper order, it has pearl nest subassembly 4 to slide respectively between being connected of well rail 2 and upper rail 1, lower rail 3, wherein, well rail 2 installs synchronous roller 5, upper rail 1 is equipped with the annular knurl 6 of being connected with synchronous roller 5 dynamic friction respectively with lower rail 3, and annular knurl 6 distributes respectively on the outer terminal surface of upper rail 1, lower rail 3.

Because the knurls 6 of the upper rail 1 and the knurls 6 of the lower rail 3 are arranged in parallel and are in surface contact with the synchronous rollers 5, when the sliding rail is opened and closed, the upper rail 1 and the lower rail 3 move at the same speed in the opposite direction relative to the middle rail 2 under the action of the common friction motion of the two knurls 6 and the synchronous rollers 5, so that the upper rail 1, the middle rail 2 and the lower rail 3 can move synchronously. Replace gear and rack structure effectively, reduce vibrations, the noise reduction, and increase frictional force avoids preventing synchronous gyro wheel 5 and skids, promotes the operating stability, and the production of noise reduction again adapts to the use of heavy drawer.

Referring to fig. 1 to 2, a groove position 7 is arranged in the middle of the middle rail 2, a positioning shaft 8 is installed at the groove position 7, and the synchronous roller 5 is installed on the positioning shaft 8. Strengthen 5 mounting structure stability of synchronous gyro wheel, ensure the synchronous operation of slide rail.

And, the middle part of well rail 2 is equipped with outside protruding enhancement position 9. Under the effect of protruding reinforcing position 9, promote the compressive strength of well rail 2, reduce the deformation, adapt to the hidden rail use of high load.

In addition, the knurls 6 are respectively arranged at the outer corner positions at the left and right sides of the opening end of the upper rail 1 and the outer corner positions at the left and right sides of the opening end of the lower rail 3.

Wherein, the knurls 6 are provided with straight-line knurls; or the knurls 6 are twill; alternatively, the knurls 6 are provided as cross-hatching.

The knurling 6 of adopting this structure, pleasing to the eye, and enlarge the area with 5 contact of synchronizing wheel, increase frictional force avoids preventing 5 skids of synchronizing wheel, promotes operating stability, guarantees the service quality of product.

Above-mentioned embodiment only does the utility model discloses the better embodiment of effect, all with the utility model discloses a heavy hidden rail that has synchronizing function is the same or equivalent structure, all is the utility model discloses a within range.
