Description

Rail device

The utility model relates to a slide rail device, in particular to a slide rail device without screws.

In modern life, the personal computer has gradually become a necessary information processing device in the family. Due to the aesthetic and quality requirements of modern life, in addition to the improvement of computing speed and memory capacity of the personal computer, the improvement of the assembly design of the casing of the personal computer is also an important consideration for improving the quality of the personal computer. One of the key points of the assembly design of the computer case is to simplify the assembly and disassembly procedures between the various parts of the module components and the case. This will not only save the product assembly time spent by the computer manufacturer, but also further satisfy many users who assemble by themselves. computer needs.

For data access devices (eg, floppy drives, optical drives), traditionally, screws are used to lock them on the combination shelf used to fix the data access devices in the casing. In general, each data access device needs to be fixed with four screws. Take the situation that a computer is equipped with a floppy drive and an optical drive as an example, that is, eight screws need to be locked to complete the fixing action. Because screw locking is a very time-consuming work, it makes the traditional fixing method seem time-consuming and troublesome. In addition, in order to fix the data access device on the combination rack, the computer casing must be disassembled before fixing it with screws, which also causes troubles that the user is not easy to disassemble and assemble.

In order to overcome the problem that the entire computer case must be disassembled in order to assemble the data access device, another traditional approach is to design slide rails on both sides of the data access device, and design corresponding slide slots inside the combination rack. Through the cooperation of the slide rail and the chute, the data access device can be directly inserted into the opening on the front of the casing without disassembling the computer host to fix it on the combination rack. Although this technology solves the shortcoming that the computer casing must be disassembled simultaneously when assembling the data access device, it cannot overcome the regret that screws must be used. Since the slide rail is not integrally formed with the housing of the data access device, it still needs to be fixed on both sides of the data access device by screws. Therefore, the conventional slide rail design still has the disadvantage of consuming man-hours. In addition, the slide rail is usually a strip-shaped plastic component, which is difficult to control the frictional force in the process of mating with the slide groove due to its non-deformable characteristics. When the friction force is too large, the user will spend a lot of effort to complete the assembly process. If the friction force is too small, the data access device will easily shake.

To sum up, it is necessary to propose a new design that can fix the data access device on the combination frame in the computer case in a labor-saving and stable manner without screws.

The purpose of this utility model is to provide a slide rail device, which works in conjunction with the combination frame on the computer case, so that data access devices (such as floppy drives, hard drives, and optical drives, etc.) can be fixed to the combination frame without screws superior.

In order to achieve the above purpose, the utility model provides a slide rail device without screws, which is used in conjunction with data access devices such as floppy drives or optical drives, so as to fix the data access device on the personal computer casing. The slide rail device is mainly composed of Composed of reeds and sliders. The reed is a metal sheet, one side of which is bent to form a raised elastic area, and the other side is bent to form a raised fixed foot. Because the fixed foot matches the aperture of the fixed hole on the side of the floppy drive or the optical drive, the reed can be fixed on the floppy drive or the optical drive without screws by matching the fixed foot with the fixed hole. The slide bar is made of elastic material and includes components such as a first guide hole and a positioning tenon. The first guide hole is located on the surface of the slide bar, and is used for accommodating the fixed feet, and the reed is combined with the slide bar by passing the fixed feet through the first guide hole. At the same time, the fixing feet protrude from one side of the slide bar and further cooperate with the fixing holes, so that the reed and the slide bar are fixed on the floppy drive or the optical drive. The positioning tenon is located on the surface of the slide bar, and the positioning tenon can be combined with the tenon and groove on the computer case, so that the relative position between the slide bar and the computer case can be established. It is fixed on the computer case without screws.

The utility model relates to a slide rail device which can be used in conjunction with data access devices (such as floppy drives, hard drives, optical drives, etc.). When using, you only need to fix the slide rail device on both sides of the data access device in a combination without screws, and then push the data access device together with the slide rail device into the opening from the front of the personal computer case and fix it Just put it on the combination rack. Because the slide rail device has a reed design that can provide elastic force, the user can securely fix the data access device on the combination rack with a small amount of effort. The following will illustrate the spirit of the utility model with a preferred embodiment proposed according to the utility model.

Referring first to FIG. 1 , it shows a three-dimensional schematic diagram of fixing the data access devices 14 and 16 on the assembly frame 12 of the computer case 10 through the slide rail device 18 of the present invention. The computer casing 10 is a design well known in the industry, and it is not necessary to make any design changes to match the present invention. It includes an assembly shelf 12 for fixing data access devices 14 , 16 . There are multiple sets of sliding slots 11 on the assembly frame 12 for matching with the sliding rail device 18 . When desiring to assemble the data access devices 14, 16 on the combination frame 12, at first the slide rail device 18 can be fixed on both sides of the data access devices 14, 16 without using screws (described later in detail), Then insert the data access devices 14 , 16 together with the slide rail device 18 from the opening on the front side of the computer case 10 in the direction of the slide groove 11 . Through the cooperation of the slide rail device 18 and the slide groove 11 , the data access devices 14 , 16 can be stably fixed on the combination rack 12 . In addition, the sliding rail device 18 also includes a mechanism design (not shown in the figure) for positioning and tenon, so that the positions of the data access devices 14 and 16 relative to the assembly rack 12 can be established. When wanting to take out the data access device 14,16, only need to press the release button 20, and the tenon mechanism is interlocked with it and loosened, thereby taking out the data storage device 14,16. Incidentally, the data access devices 14, 16 can be floppy drives and optical drives, but devices such as hard drives can also be used in conjunction with the slide rail device 18 of the present invention according to the needs of practical applications.

FIG. 2 illustrates the components of the slide rail device 18 by taking the three views of the data access device 14 as an example. As shown in FIG. 2C , the side of the data access device 14 has a plurality of fixing holes 22 a , 22 b for connecting the slide rail device 18 . The front side of the slide rail arrangement 18 has one or more elastic regions 26 . In this preferred embodiment, the elastic region 26 is a bent metal sheet. Through the structural elasticity produced after the metal sheet is bent, when the data access device 14 is inserted, a force is generated relative to the chute 11 (see Figure 1) of the assembly frame 12, so that the data access device 14 can be stably fixed in it. In addition, because the slide rail device 18 does not rub against the slide groove 11 with the entire front, the power required to insert the data access device 14 in the present utility model will be smaller than the traditional slide rail.

In addition, the top surface and the bottom surface of the slide rail device 18 respectively have webs 24 that expand and bend slightly outward. Since the slide rail assembly 18 itself is made of elastic plastic material, the web 24 is shaped to provide elastic deformation along the top and bottom surfaces. When the data access device 14 is inserted into the chute 11 (see FIG. 1 ), most of the frictional force on the top and bottom surfaces of the slide rail device 18 will be borne by the web 24 instead of being borne by the entire top and bottom surfaces. Due to the reduction of the frictional surface, the force required to insert the data access device 14 can be greatly reduced, and at the same time, because the web 24 has an elastically deformable profile, the data access device 14 will be in the direction of the top surface-bottom surface Also keeps it stable without wobbling.

A positioning tenon 30 is also designed on the slide rail device 18 . The positioning tenon 30 is a wedge-shaped object with a one-way slope, so it can allow the data access device 14 to be inserted into the sliding slot 11 (see FIG. 1 ). However, after the data access device 14 is positioned, the positioning tenon 30 will be combined with the mortise (not shown) on the assembly frame 12 (see Figure 1), and prevent the data access device 14 from inserting along the opposite direction. Orientation slide out. At the same time, the flange 28 on the slide rail device 18 limits the maximum depth that can move into the slide groove 11 . Therefore, by positioning the tenon 30 and the flange 28, the data access device 14 can be positioned at a desired specific position. When wanting to take out the data access device 14, only need to press the release button 20, and the positioning tenon 30 will break away from the tenon groove, and it can be taken out.

Please refer to FIG. 3 , which shows an exploded perspective view of the components inside the slide rail device 18 combined with the data access device 14 . As shown in the figure, the slide rail device 18 can be mainly divided into a slide bar 19 made of plastic material and a reed 25 used in combination therewith. In this preferred embodiment, the reed 25 is an integrally formed metal sheet, and has outwardly bent elastic regions 26a, 26b on its front side, while its other side has downwardly bent into about ninety degrees. The fixing feet 38 and the clips 40 folded toward each other. The sliding bar 19 has a first guide hole 32 and a second guide hole 34 . The reed 18 is combined with the slide bar 19 into the slide rail device 18 of the present invention by inserting the fixing pin 38 and the clip 40 into the first guide hole 32 and the second guide hole 34 respectively, and then the fixing pin 38 is inserted into any The slide rail device 18 can be fixed on the side of the data access device 14 in the pair of fixing holes 22a, 22b, 22c, 22d.

Since the width of the fixing foot 38 is almost equal to the diameter length of the fixing hole 22, it can be inserted therein with a moderate tolerance. When the slide rail device 18 is inserted into the combination rack 12 (see FIG. 1 ) along with the data access device 14 , a slight deformation will occur due to the positive compression of the elastic regions 26a, 26b. As a result of the inward deformation of the elastic regions 26a, 26b, the fixing feet 38 are pushed sideways, causing the fixing feet 38 to move away from the diameter of the fixing hole 22 to create a tight fit with the shorter length of the string. Therefore, the slide rail device 18 of the present invention can be tightly fixed on both sides of the data access device 14 .

In this preferred embodiment, the position of the reed 25 is designed according to the size specification of the optical drive, and if it is to be applied to a floppy drive, it only needs to be adjusted slightly. In addition, the number of elastic regions 26 is not limited to two, and can be increased or decreased as required. The main function of the clip 40 is to clamp the second guide hole 34 so that the reed 25 and the slide bar 19 can be combined more tightly. However, other designs capable of combining the reed 25 with the sliding bar 19 should also be considered as equivalent replacements.

Finally, please refer to FIG. 4 , which shows a three-dimensional schematic view of the front and back of the slide rail device 18 of the present invention. The positioning tenon 30 and the flange 28 can be positioned along the horizontal direction, and the web 24 can be positioned along the direction of the top surface-bottom surface, while the elastic regions 36a, 36b can provide the required binding force of the data access device, so that the user can The user can insert the data access device into the computer case without spending a lot of effort, and it can be stably fixed on the combination rack. In addition, through the cooperation of the fixing feet 38 and the fixing holes, the slide rail device 18 can be fixed on the data access device without screws. In this way, through the slide rail device 18 of the present utility model, the assembly between the data access device and the computer casing can be completed without using screws at all, which shortens the working time and facilitates the computer and data access. Assembly and maintenance of devices.

The utility model has been described above with a preferred embodiment, and it should be understood that this is only used to help understand the implementation of the utility model, rather than limiting the spirit of the utility model. After comprehending the spirit of the utility model, those skilled in the art can make various modifications and equivalent replacements without departing from the scope of the spirit of the utility model.
