The utility model relates to a hanging-hole type sliding rail, which at least includes a first rail and a second rail. The first rail is crossly connected to the second rail, rolling balls are distributed between the first rail and the second rail as moving medium and the first rail and the second rail can slide and expand, wherein the first rail is equipped with a hanging hole, the hanging hole is provided with an opening, the opening is equipped with conjoint bridged segments, and a curved surface is arranged on the bridged segments, thereby the rolling balls can roll along the bridged segments and go through the opening of the hanging hole when the first rail expands.

Description

Hanging hole formula slide rail

Technical field

The utility model relates to a kind of flexible slide rail, relates to the flexible slide rail of a kind of hanging hole formula specifically.

Background technology

In the field of general computer system device, how rack-mount server can be installed on the both sides of server drain pan in conjunction with slide rail, and be erected on the pillar of rack by slide rail and carriage, server is convenient directly to pull out the rack outside to make, and is beneficial to and inspects maintenance.

The early stage employed slide rail of this class rack-mount server does not have ball mostly as the slip medium, and comparatively require great effort during pull, but it is for making the server Fast Installation on slide rail in addition, also have the design of hanging hole on the slide rail, and the early stage technology of this class is in patent documentation, United States Patent (USP) bulletin case the 6th, 209,979 B1 numbers and the 6th, 601,933B1 number i.e. exposure to some extent.

And see the disclosed early stage slide rail of above-mentioned patent documentation, it is to be used for the roller type sliding part.Its designed hanging hole upper end is for having a linkage section, and makes the rail body intensity at hanging hole place be unlikely to significantly to reduce.But such structure can only be implemented on this kind and not have a slide rail of ball, and reason is the linkage section section of this hanging hole upper end, and the supporting surface that can't provide ball one to roll.

The utility model content

The purpose of this utility model is to provide a kind of hanging hole formula slide rail, can't provide the ball problem that rolling is supported with the hanging hole structure that solves existing slide rail.

The utility model is by realizing that the utility model purpose is adopted technical scheme as follows:

A kind of hanging hole formula slide rail, include first rail, second rail and ball, wherein, first rail comprises first main body of central authorities and first groove of both sides, first groove of both sides is corresponding dorsad and outwardly, and first main body is provided with hanging hole, and hanging hole has an opening and extends to first groove, and corresponding on first groove of opening part and have a continuous bridge joint sections, this bridge joint sections has a curved surface for the ball contact; Second rail comprises second main body of central authorities and second groove of both sides, and second groove of both sides is corresponding in opposite directions and inwardly; Ball then is arranged between second groove of first groove of first rail and second rail, and when first rail is flexible, and ball can roll along the curved surface of bridge joint sections and can be by the opening of hanging hole.

Wherein, hanging hole has vertical channel and the level trough that is connected, and the upper end and the opening of this vertical channel join.

Wherein, hanging hole is a skewed slot, and the upper end and the opening of skewed slot join.

Wherein, the curved surface of bridge joint sections is an arcwall face.

Wherein, the angle face of the curved surface of bridge joint sections for joining and form by two planes.

The utility model has the following advantages compared to prior art: slide rail makes things convenient for except that possessing hanging hole the extraction-type object Fast Installation combination of server and so on, it can also be implemented on and use the flexible slide rail of ball as the slip medium, makes slide rail have the convenience in the use and the sliding compliance of pull concurrently.

The specific embodiment

Shown in the exploded view of Fig. 1 and shown in the constitutional diagram of Fig. 2, the utility model specific embodiment includes first rail 1, second rail 2 and ball 3, wherein:

First rail 1, comprise first main body 11 of central authorities and first groove 12 of both sides, first groove 12 of both sides is corresponding dorsad and outwardly, and first main body 11 is provided with hanging hole 13, hanging hole 13 has the vertical channel 131 and level trough 132 that is connected, the upper end of vertical channel 131 also is provided with an opening 133 and extends to first groove 12, and corresponding on first groove 12 at opening 133 places and have a continuous bridge joint sections 14, bridge joint sections 14 is for having a curved surface 141 for ball 3 touch scrollings, and ginseng as shown in Figure 3, and this curved surface 141 is an arcwall face;

Second rail 2 comprises second main body 21 of central authorities and second groove 22 of both sides, and second groove 22 of both sides is corresponding in opposite directions and inwardly;

Ball 3 is joined shown in Figure 3ly, is arranged between second groove 22 of first groove 12 of first rail 1 and second rail 2, and when making relative second rail 2 of first rail 1 flexible, ball 3 is promptly in

first groove

12 and 22 rollings of second groove; For another shown in Figure 1, ball 3 can be kept the spacing of its distribution by pearl nest bar 31, but the kenel of this pearl nest bar 31 is not limited to disclose among the figure, and also non-patent characteristic of the present utility model is so will not give unnecessary details again.

In addition, as shown in Figure 4, the bridge joint sections 14A that the first rail 1A establishes in hanging hole 13A place, the angle face of its curved surface 141A for joining and form by two planes, when the relative second rail 2A of the first rail 1A was flexible, ball 3A can be contacted with this angle face and roll, to pass through hanging hole 13A.

And for example shown in Figure 5, the hanging hole 13B on the first rail 1B can be the skewed slot kenel that a upper end has opening 133B.

In addition, as shown in Figure 6, for the three-sectional sliding-rail that further comprises one the 3rd rail 4C is implemented kenel, it removes and be provided with ball 3C between the first rail 1C and the second rail 2C, outside flexible, the second rail 2C also is extended with outer channel 23C by the second groove 22C reflexed, and is provided with other ball 5C between the outer channel 23C of and the second rail 2C inner in the 3rd rail 4C.

According to above explanation, enhancement effect of the present utility model as can be known and advantage promptly are:

Slide rail makes things convenient for server and so on except that possessing hanging hole extraction-type object Fast Installation in conjunction with, it more can be implemented on and use the flexible slide rail of ball as the slip medium, makes slide rail have the convenience in the use and the sliding compliance of pull concurrently.

Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, under the situation that does not break away from the utility model spirit, also can make the variation and the modification of various equivalences, therefore, as long as variation, the modification to the foregoing description all will drop in the scope of the utility model claims in connotation scope of the present utility model.
