Description

Extraction track device for computer equipment

technical field

The utility model relates to an extracting track device for computer equipment, in particular to an inner and outer sliding track, which can be quickly and conveniently fixed on frame elements of different specifications.

Background technique

A typical example of a traditional extraction track device for computer equipment, as shown in Figure 8, is formed by sliding an outer track body A to an inner track B, and the inner track B is screwed to a fixing member C; as shown in Figure 9, A frame group D, measure the size in advance between the front and rear longitudinal frames E ₁ and E ₂ , and then pre-assemble the three combined lengths of the outer rail body A, the inner rail B and the fixing part C according to the measured correct size , so that the combined length of the outer rail body A, the inner rail B and the fixing piece C is the same as the length between the front and rear longitudinal frames E ₁ and E ₂ . Fix the fixed end _A1 of the assembled outer rail body A on the front longitudinal frame _E1 , and fix the fixing part C on the rear longitudinal frame _E2 . This traditional technology has the following disadvantages during construction:

(1) The dimensional distance between the front and rear longitudinal frames E ₁ and E ₂ must be measured, and the outer rail body A, inner rail B and fixing piece C must be assembled outside the frame body group D in advance, and then assembled on The front and rear longitudinal frames are mounted on E ₁ and E ₂ , so it is a waste of construction time and inconvenience in construction.

(2) Since the extraction track device is composed of three parts such as the outer rail body A, the inner track B and the fixing C, there are many other parts in the combination, and the stress strength is relatively poor.

(3) Only one convex column F is used as support between the outer rail body A and the inner rail B. Therefore, when the inner track B and the outer track body A slide relative to each other, the stability, mobility and strength of the horizontal displacement are poor.

The outer rail body 10 is provided with a front fixing part 12 at the outer end, and a main chute 14 is formed inside. The center of the groove bottom of the main chute 14 is provided with a central recess 16, and the central recess 16 is protrudingly provided with a fixed post 161, along which The side of the central recess 16 is provided with a side slide groove 17 (17);

The inner track 20 is a long strip body, the rear end has a rear fixing part 24, and a main chute 25 is formed inside, and a strip perforation 22 is provided on the bottom surface of the main chute 25, and the strip perforation 22 has a back stop part 222, at least one post 26 (26) is fixed on the back plate, and the post 26 (26) slides into the side slide groove 17 (17) of the outer rail body 10, on the outer rail body 10 The fixed boss 161 slides into the strip perforation 22;

The inner track 20 can slide and shift in the main chute 14, and the strip perforation 22 uses the fixed boss 161 as a guide rod to slide and shift, and the back stop 222 can push (stop) on the fixed boss 161, The boss 26 (26) on the inner rail 20 can slide and displace in the sliding groove 17 (17).

As shown in Figure 1, the outer rail body 10 is riveted and fixed as a whole by the outer shell 101 and the inner shell 102, and the chute 17, the front fixing part 12 and the central recess 16 are arranged on the inner shell 102, wherein the chute 17 One end of (17) is provided with a blocking portion 171 , and the fixing post 161 is fixedly connected to the central concave portion 16 .

As shown in Figure 5, the front fixing parts 12 of the two outer rail bodies 10 are respectively fixed on the two rear beams 52 (52) of the frame group 50; the rear fixing parts 24 of the inner rail 20 are respectively fixed on the frame group 50 On the two front beam frames 54 (54).

As shown in Figure 5 , on the main chute 25 of the inner track 20, an inner slide plate 32 is slidingly connected. Sliding displacement on the chute 25.

As shown in FIG. 6 and FIG. 7 , the bosses 26 fixed on the inner track 20 and the bosses 161 of the outer rail body 10 are provided with annular tops 261 and 162 with larger outer diameters above them.

The utility model is described in detail below.

As shown in Figure 1, the outer rail body 10 is riveted and fixed by the outer casing 101 and the inner casing 102, so the overall stress strength of the outer rail body 10 can be improved, and two protrusions 26 (26) shuttle on both sides In the chute 17 (17), as shown in Figure 7, the annular top 261 is positioned on the groove wall surface of the chute 17 (17), so when the inner track 20 slides and shifts in the main chute 14, the two bosses 26 (26) slide along the two parallel slide grooves 17 (17); as shown in Figure 6, another fixed boss 161 and the strip perforation 22, etc., can slide relatively, so the inner track 20 is outside When sliding on the rail body 10, it is supported by three bosses 161, 26 (26) (as shown in FIG. 4 ), so that the sliding action is stable, the flexibility of sliding is improved, and the strength of force is further enhanced.

As shown in FIG. 6 , the fixing boss 161 has an annular top 162 with a large outer diameter, and the top 162 is located on the edge of the elongated hole 22 to limit the movement between the inner rail 20 and the outer rail body 10 from left to right. Misalignment, that is, when the control inner rail 20 slides and displaces in the main chute 14, a large gap is not expected to be generated.

As shown in Figure 7, there are annular tops 261 (261) with larger outer diameters on the two bosses 26 (26), and the two tops 261 (261) are positioned on the groove wall surfaces of the two side chute 17 (17), further Then control the sliding gap between the inner rail 20 and the outer rail body 10 to be small, that is, when the inner rail 20 slides and shifts in the main chute 14, a larger gap will not be generated to improve the inner rail 20 and the outer rail body 10. The tightness of sliding joints with each other.

As shown in Figure 5, during construction, as long as the inner rail 20 and the outer rail body 10 that have been assembled by sliding are adjusted together, the distance between the front beam frame 54 and the rear beam frame 52 is stretched and adjusted, so that the front fixed part 12 can be easily adjusted. Corresponding to contact with the rear beam frame 52, the rear fixing part 24 is easily correspondingly contacted with the front beam frame 54, and then locked by the bolt 55 (as shown in Figure 3), the combination of the outer rail body 10 and the inner rail 20 is Fast fixed on the frame group 50; the computer equipment 30 can be a computer mainframe or a server, and the inner sliding plate 32 fixed on its two sides can slide into the main chute 25 of the inner track 20, for the computer equipment 30 and If it is pulled or pushed in, the two slide plates 32 can slide in the main chute 25, and the computer equipment 30 can be pulled or pushed in in the frame group 50. At this time, the three bosses 161, 26, (26) respectively It is supported and positioned in the two chute 17 and the strip perforation 22, so that the combination of the inner rail 20 and the outer rail body 10 is stable and can carry a larger moment.

Thereby, the present invention can quickly lock and position the inner rail 20 and the outer rail body 10 without measuring the distance between the front beam frame 54 and the rear beam frame 52 in advance.
