Description

Hanging hole type slide rail

technical field

The utility model relates to a telescopic slide rail, in particular to a hanging hole type telescopic slide rail.

Background technique

In the field of general computer system equipment, rack-mounted servers are usually installed on both sides of the server bottom shell combined with slide rails, and are erected on the pillars of the cabinet with the help of slide rails and brackets, so that the server can be easily pulled out of the cabinet directly. Outside, it is convenient for inspection and maintenance.

Most of the slide rails used in this type of rack-mounted servers in the early days did not have balls as the sliding medium, and it was more laborious to pull them out. In addition, in order to allow the server to be quickly installed on the slide rails, there were also hanging holes on the slide rails. Designs, and such early technologies are disclosed in the patent literature, US Patent Publication No. 6,209,979 B1 and No. 6,601,933 B1.

And look at the early slide rails disclosed in the above-mentioned patent documents, which are used for roller-type sliders. The upper end of the hanging hole is designed to have a connecting section, so that the strength of the rail body at the hanging hole will not be greatly reduced. But such a structure can only be implemented in this kind of slide rail without balls, because the cross-section of the connecting section at the upper end of the hanging hole cannot provide a supporting surface for balls to roll.

Utility model content

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

A hanging hole type slide rail, including a first rail, a second rail and balls, wherein, the first rail includes a first main body in the center and first grooves on both sides, and the first grooves on both sides are opposite to each other And facing outward, and the first body is provided with a hanging hole, the hanging hole has an opening extending to the first groove, and corresponds to the first groove at the opening and has a connected bridging section, the bridging section has a supply The curved surface that the balls contact; the second rail includes the second main body in the center and the second grooves on both sides, and the second grooves on both sides are opposite to each other and face inward; the balls are arranged on the first groove and the second groove of the first rail Between the second grooves of the two rails, when the first rail stretches, the balls can roll along the curved surface of the bridge section and pass through the opening of the hanging hole.

Wherein, the hanging hole has a connected vertical groove and a horizontal groove, and the upper end of the vertical groove is connected with the opening.

Wherein, the hanging hole is a chute, and the upper end of the chute is connected with the opening.

Wherein, the curved surface of the bridging section is an arc surface.

Wherein, the curved surface of the bridging section is an angled surface formed by connecting two planes.

Compared with the prior art, the utility model has the following advantages: in addition to the slide rail having hanging holes to facilitate the quick installation and combination of extractable objects such as servers, it can also be implemented in telescopic slide rails using balls as sliding media, so that The slide rail has both the convenience of use and the smoothness of pulling.

Detailed ways

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

The first rail 1 includes a first main body 11 in the center and first grooves 12 on both sides. The first grooves 12 on both sides are opposite to each other and face outwards, and the first main body 11 is provided with a hanging hole 13 for hanging The hole 13 has a connected vertical groove 131 and a horizontal groove 132. The upper end of the vertical groove 131 is provided with an opening 133 extending to the first groove 12, and corresponding to the first groove 12 at the opening 133 and has a connected bridge. Section 14, the bridging section 14 has a curved surface 141 for the ball 3 to contact and roll, and as shown in Figure 3, the curved surface 141 is an arc surface;

The second rail 2 includes a central second main body 21 and second grooves 22 on both sides, and the second grooves 22 on both sides correspond to each other and face inward;

The ball 3, as shown in Figure 3, is arranged between the first groove 12 of the first rail 1 and the second groove 22 of the second rail 2, so that when the first rail 1 expands and contracts relative to the second rail 2, the ball 3 That is, it rolls between the first groove 12 and the second groove 22; as shown in Figure 1, the balls 3 can maintain their distributed spacing by means of the ball nest bar 31, but the pattern of the ball nest bar 31 is not limited to that shown in the figure. Disclosed in, also not the patent feature of the present utility model, so give no more details.

In addition, as shown in FIG. 4 , the bridge section 14A provided on the hanging hole 13A of the first rail 1A has a curved surface 141A that is an angled surface formed by connecting two planes, and is stretchable on the first rail 1A relative to the second rail 2A. At this time, the ball 3A can roll in contact with the angled surface to pass through the hanging hole 13A.

Also as shown in FIG. 5 , the hanging hole 13B on the first rail 1B can be in the form of a chute with an opening 133B at the upper end.

In addition, as shown in FIG. 6 , it is a three-section slide rail implementation that further includes a third rail 4C, except that a ball 3C is provided between the first rail 1C and the second rail 2C to facilitate expansion and contraction. , the second rail 2C has an outer groove 23C extended from the second groove 22C, and another ball 5C is provided between the third rail 4C and the outer groove 23C of the second rail 2C.

According to the above description, it can be seen that the enhanced effect and advantages of the present utility model are:

In addition to having hanging holes to facilitate the quick installation and combination of removable objects such as servers, the slide rail can also be implemented in telescopic slide rails that use balls as the sliding medium, making the slide rail both convenient in use and easy to pull. smoothness.

Although the utility model has been described with reference to the current specific embodiments, those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the utility model, without departing from the spirit of the utility model Various equivalent changes and modifications can also be made.
