Description

Computer case

The invention relates to a computer case which can be easily assembled and disassembled.

One side of the computer case is usually provided with an opening. When assembling a component such as a motherboard or a hard disk, the computer manufacturer can first pass each component through the opening and fix it in the computer case, and then fix one side plate to the opening. This achieves the closure of the computer case.

Usually, the way to fix the side panel of the computer is to directly lock the side panel of the computer to the computer base with screws. However, this method requires a screw driver or the like to fix the screw to fix the left and right side panels to the computer base. The assembly process is rather cumbersome and time consuming, and wastes manpower and man-hours.

In view of this, it is necessary to provide a computer case that can be easily assembled and disassembled.

A computer case including a case and a side panel. The casing is a frame structure and has an opening on one side to mount the side plate. The computer case also includes a locking lever and an operating member. The inner side of the side plate is provided with a limiting portion, and the locking rod passes through the limiting portion and can move toward the inner side of the limiting portion. A corresponding hook is arranged on each side of the casing corresponding to the two ends of the locking rod. The operating member is disposed outside the side panel and connected to the locking rod. The operating member is toggled so that both ends of the locking rod simultaneously enter or disengage the two hooks to fix the side panel to the casing or to remove the side panel from the casing.

By simply pushing the operating member and driving the two ends of the locking rod into or out of the two hooks, the side panels can be assembled and disassembled, and the whole process is convenient and quick.

The computer case of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 and FIG. 2 together, the computer case 100 of the embodiment of the present invention includes a casing 10 and a side plate 20. The casing 10 has a frame structure and forms an accommodation space. The casing 10 has an opening 11. The side plate 20 is mounted on the casing 10 and fixed thereto to close the opening 11.

Referring to FIG. 3 together, the computer case 100 further includes a locking bar 30. A limiting portion 21 is provided on a side of the side plate 20 facing the casing 10. A first through hole 211 extending in the Z-axis direction is formed in the limiting portion 21 . The locking rod 30 is an elongated rod that passes through the first through hole 211 and is movable back and forth in the Y-axis direction in the first through hole 211. The width of the first through hole 211 along the X axis is greater than the thickness of the locking rod 30 along the X axis, so the locking rod 30 can also move back and forth along the X axis direction. The limiting portion 21 further defines a first elastic member 23 in the first through hole 211. The first elastic member 23 has one end fixed to the inner side of the first through hole 211 and the other end abutting the middle of the locking rod 30. In the initial state, the locking bar 30 is located at one end of the first through hole 211 by being resisted by the first elastic member 23. In this embodiment, the first elastic member 23 is a compressible elastic piece.

A second through hole 213 communicating with the first through hole 211 is defined in a position of the side plate 20 away from the one side of the casing 10 and opposite to the limiting portion 21 . The computer case 100 also includes an operating member 40. The operating member 40 includes an operating lever 41 and an operating portion 43 connected to the operating lever 41. After the operating rod 41 passes through the second through hole 213, it is fixedly connected to the middle of the locking rod 30. The length of the operating lever 41 is larger than the width of the second through hole 213 along the X-axis, so that the pressing operation portion 43 can push the operating lever 41 and the locking lever 30 connected thereto back and forth in the X-axis direction. The operation portion 43 is located on the outer side of the side plate 20. The width of the operating portion 43 is greater than the width of the second through hole 213. The operation portion 43 is also provided with an inclined surface 431 which is easy to handle by hand. The bottom end of the second through hole 213 is provided with a narrow width stop portion 2131. A spring 25 is also disposed on the side panel 20. The spring 25 is sleeved on the operating lever 41, and one end thereof abuts against the stopper portion 2131, and the other end abuts against one side of the operation portion 43. The spring 25 is used to provide a restoring force for the operating rod 41 to move back and forth in the second through hole 213.

Referring to FIG. 2 and FIG. 4 together, the casing 10 includes an upper plate 15 and a plate 17 opposite thereto. A portion of the lower plate 17 near the edge is provided with a rib 171 which can abut against the side plate 20. The rib 171 is provided with a first opening 1711 and a second opening 1713. The first opening 1711 is the same width as the second opening 1713 and can allow the locking rod 30 to pass therethrough. The lower plate 17 is also provided with a hook 173 and a guiding block 175 inside the rib 171. The hook 173 extends inwardly from the rib 171 between the first opening 1711 and the second opening 1713 and is bent away from the first opening 1711. The outer side of the bent portion of the hook 173 is a circular arc-shaped guide surface 1731 (see Fig. 5). The guide block 175 is adjacent to the hook 173 and is located on the side of the second opening 1713. A gap 177 is formed between the guide block 175 and the end of the hook 173 to allow the locking rod 30 to pass therethrough. A portion of the guiding block 175 corresponding to the second opening 1713 is provided with an inclined surface 1751 for guiding the locking rod 30 into the second opening 1713 (to facilitate viewing of the inclined surface 1751, the upper right corner of the protruding strip 171 is partially cut).

Similar to the lower plate 17, the upper plate 15 is also provided with a ridge, a hook and a guide block (both not shown).

5 to 8 are schematic views showing the assembly and disassembly process of the chassis 100 of the present invention.

Referring to FIG. 5, when assembling the chassis 100, the side plates 20 are first placed in the openings of the casing 10 such that the edges of the side plates 20 are in contact with the ribs 171. In the initial state, the locking bar 30 at one end of the first through hole 211 passes through the first opening 1731 and is located on one side of the hook 173.

Referring to FIG. 6, when the pushing operation member 40 is moved laterally along the second through hole 213, the locking rod 30 will also move in the negative direction of the Y-axis, and at this time, the first elastic member 23 is in a gradually compressed state. When the locking rod 30 contacts the guiding surface 1731 of the hook 173, the locking rod 30 is slightly moved in the positive direction of the X-axis due to the slanting thrust from the guiding surface 1735, and finally passes over the guiding surface 1731 and is located in the hook Above the 173. At this time, the operating member 40 will also move slightly in the positive direction of the X-axis to compress the spring 25.

Referring to FIG. 7, when the pushing operation member 40 is further moved laterally along the second through hole 213, the locking lever 30 will also continue to move in the negative direction of the Y-axis. When the lock lever 30 is moved to the gap 177 between the guide block 175 and the hook 173, the application of the lateral thrust to the operating member 40 is stopped. At this time, under the elastic restoring force of the spring 25, the locking rod 30 will move through the gap 177 in the negative direction of the X-axis. When the locking rod 30 is moved to the right side of the hook 173, under the elastic restoring force of the first elastic member 23, the locking rod 30 will move in the positive direction of the Y-axis and bypass the end of the hook 173 to enter. Inside the hook 173. After entering the hook 173, the locking rod 30 cannot move along the X-axis or the Y-axis, so the side panel 20 is relatively firmly locked to the casing 10.

There are two ways to remove the side panel 20. Referring to FIG. 8, in the first method, the operating member 40 can be pushed to move in the negative direction of the Y-axis. When the locking rod 30 moves in the negative direction of the Y-axis to contact with the inclined surface 1751 of the guiding block 175, the locking is performed. The rod 30 is slightly moved in the negative direction of the X-axis due to the slanting thrust from the inclined surface 1751, and finally passes over the inclined surface 1751 and is located directly above the second opening 1713. Since the locking bar 30 can pass through the second opening 1713, the side plate 20 can be removed from the casing 10 more easily at this time. After the side plate 20 is removed, the locking lever 30 automatically returns to the initial position of the leftmost end of the first through hole 211 under the elastic restoring force of the first elastic member 23.

In the second method, the locking rod 30 can be moved in the negative direction of the Y-axis directly below the gap 177, and then the operating portion 43 of the operating member 40 is pressed to cause the locking rod 30 to pass through the gap 177 and be located in the hook 173 obliquely above. After the urging force is applied, under the elastic restoring force of the first elastic member 23 and the spring 25, the locking rod 30 will first move in the negative direction of the X-axis and directly above the first opening 1711 in the positive direction of the Y-axis. Since the locking bar 30 can pass through the first opening 1711, the side plate 20 can be removed from the casing 10 more easily at this time.

It can be understood that when the side plate 20 is installed, the operating member 40 can also be pushed forward in the negative direction of the Y-axis, so that the locking rod 30 is located at the rightmost end of the first through hole 211. At this time, the side panel 20 is placed in the opening of the casing 10, and the locking bar 30 will just pass through the second opening 1713 to the right of the hook 173. After the application of the force is stopped, the locking rod 30 will automatically enter the hook 173 to complete the locking under the elastic restoring force of the first elastic member 23.

It can be understood that the first elastic member 23 and the spring 25 can be omitted. If the second disassembly method is adopted, the guiding block 175 and the second opening 1713 may also be omitted. If the second mounting method is adopted, the first opening 1711 can also be omitted.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
