[0025] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a computer case housing that is easy to maintain, including: a case unit 100 and a power supply quick positioning unit 200.

[0026] The chassis unit 100 includes a chassis shell 101 and a chassis side plate 102 matched with the chassis shell 101. A heat dissipation port is provided on one side of the chassis shell 101. A dustproof net 105 is magnetically attracted in the heat dissipation port. The dustproof net 105 can ensure that the heat accumulated in the chassis shell 101 is normally diffused outward, and can prevent large particles of impurities in dust from entering the chassis shell 101. A power supply mounting frame 103 is fixedly installed at one end of the chassis shell 101. A computer power supply 104 is arranged on the power supply mounting frame 103. The computer power supply 104, the power supply mounting frame 103 and the chassis shell 101 are all inherent components of the computer. The specific working principles and structures of the three are not described in detail here. The power supply mounting frame 103 is provided with multiple groups of evenly distributed through-holes, and the multiple groups of through-holes are all arranged in strips. Through the arrangement of the through-holes, the defect that the heat generated by the long-term operation of the computer power supply 104 is easily accumulated at the connection between the computer power supply 104 and the power supply mounting frame 103 and is difficult to diffuse is effectively solved;

[0027] Furthermore, the power supply quick positioning unit 200 includes two supporting ears 201 fixedly installed on the end of the power supply mounting frame 103 away from the chassis shell 101, each supporting ear 201 is rotatably connected to the inner wall of the chassis shell 101 through a corresponding semi-threaded rod 202, each semi-threaded rod 202 is threadedly connected to a threaded sleeve 203 at one end away from the chassis shell 101, and the two threaded sleeves 203 are commonly fixedly connected to a clamping plate 204, the clamping plate 204 is abutted against the side of the computer power supply 104 away from the chassis shell 101, a positioning ear 205 is fixedly installed on one side of the computer power supply 104, a positioning hole is opened on the positioning ear 205, and a positioning column 206 matching the positioning hole is fixedly installed on the inner wall of the chassis shell 101, through the coordinated use of the positioning ear 205 and the positioning column 206, the coordination stability between the computer power supply 104 and the power supply mounting frame 103 is further improved, and the power supply quick positioning unit 200 also includes a synchronous drive component 207 for synchronously driving the two semi-threaded rods 202.

[0028] Furthermore, the synchronous drive assembly 207 includes a protective box 207a fixedly mounted on the outside of the chassis shell 101, and one end of each semi-threaded rod 202 away from the supporting ear 201 is inserted into the protective box 207a and fixedly connected to a worm gear 207c. The inner walls on both sides of the protective box 207a are connected to a worm 207b that is meshed with the worm gear 207c and rotates together, and one end of the worm 207b passes through the protective box 207a outward and is fixedly connected to a knob.

[0029] A blocking cover 207d is provided at one end of the protection box 207a away from the chassis shell 101, and the blocking cover 207d is fastened to the protection box 207a by multiple groups of evenly distributed fastening screws 207e; by using the blocking cover 207d and the fastening screws 207e in combination, the meshing position of the worm 207b and the worm wheel 207c inside can be wrapped and protected to ensure the meshing stability of the worm 207b and the worm wheel 207c.

[0030] During use, when the computer power supply 104 needs to be inspected and maintained and the computer power supply 104 needs to be disassembled, the worm 207b is rotated in the forward direction, and the worm wheel 207c meshing with it rotates accordingly, the semi-threaded rod 202 rotates, and the threaded sleeve 203 threadedly connected with it can be quickly separated from the computer power supply 104 through the clamping plate 204, so that the staff can more conveniently remove the computer power supply 104 from the power supply mounting frame 103. Conversely, the worm 207b is reversed to reposition the computer power supply 104. The computer power supply 104 can be disassembled and installed by controlling the worm 207b, without the need to use special tools to loosen or tighten multiple sets of fastening screws in sequence, which greatly shortens the maintenance and inspection time of the computer power supply 104.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
