Description

Technical Field

[0001] The invention relates to the field of computer heat dissipation, and in particular to a computer heat dissipation fan which is easy to install. Background Art

[0002] Integrated circuits are widely used in computer components. As we all know, high temperature is the enemy of integrated circuits. High temperature will not only cause unstable system operation and shorten service life, but may even burn some components. The heat that causes high temperature does not come from outside the computer, but from inside the computer, or inside the integrated circuit. The function of the radiator is to absorb this heat and then dissipate it into or outside the chassis to ensure the normal temperature of computer components. Most radiators absorb heat by contacting the surface of the heat-generating components, and then transfer the heat to a distant place through various methods, such as the air in the chassis, and then the chassis transfers the hot air to the outside of the chassis to complete the heat dissipation of the computer. There are many types of radiators, including CPU, graphics card, motherboard chipset, hard disk, chassis, power supply, and even optical drive and memory. These different radiators cannot be mixed, and the most commonly used one is the CPU radiator.

[0003] In order to ensure the normal operation of the CPU inside the computer host, a cooling fan is generally installed inside the computer host when in use. When installing the existing cooling fan, four connecting ears are generally set on its circumferential side wall, and then the connecting ears are fixed to the host shell plate by screws. This installation method is more troublesome and time-consuming. Therefore, in order to solve such problems, we propose a computer cooling fan that is easy to install. Summary of the invention

[0004] The invention provides a computer cooling fan that is easy to install, which solves the problem that the existing cooling fans are inconvenient to install, which results in inconvenience in repairing and consuming a lot of time after a failure occurs.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A computer cooling fan that is easy to install comprises a mainframe casing plate, an adjusting toothed ring, a fixing plate, a holding spring, a mounting sleeve and a cooling fan, wherein an adjusting toothed ring is rotatably mounted on the inner side of the mainframe casing plate, and a fixing plate is fixedly connected to the inner side of the mainframe casing plate, the fixing plate is located inside the adjusting toothed ring, a holding spring is fixedly connected to an inner wall of one side of the fixing plate, and a movable ring is fixedly connected to the end of the holding spring, a cooling fan is installed inside the mounting sleeve, and the mounting sleeve is located between the fixing plates, a circumferential outer wall of the mounting sleeve is fixedly connected to connecting ears distributed in a ring array, a gear plate is rotatably mounted on a side of the fixing plate away from the mainframe casing plate, and the gear plate meshes with a tooth block on the inner wall of the adjusting toothed ring, and a threaded rod is threadedly provided on the gear plate.

[0007] Preferably, the fixing plates are arranged in a ring array, and the fixing plates are matched with the connecting ears.

[0008] Preferably, the cross-section of the fixing plate is arranged in a U-shaped structure.

[0009] Preferably, the end of the connecting ear is arranged in a semicircular structure.

[0010] Preferably, positioning holes are provided on the connecting ear and the fixing plate, and the threaded rod matches the positioning holes.

[0011] Preferably, heat dissipation holes with the same structure are evenly arranged on the main housing plate.

[0012] The beneficial effects of the present invention are:

[0013] 1. By placing the connecting ear and the fixing plate in a staggered manner and pushing the installation sleeve so that it drives the connecting ear to squeeze the movable ring, and then rotating the installation sleeve so that the connecting ear is inserted into the fixing plate, the cooling fan can be installed more easily and quickly.

[0014] 2. By rotating the adjusting gear ring, the gear plate is driven to rotate, so that the threaded rod can be inserted into the positioning hole, thereby effectively fixing the installed cooling fan, eliminating the traditional steps of installing screws one by one, and improving the stability of the cooling fan installation.

[0015] In summary, the device changes the traditional operation steps of installing screws one by one, can quickly and stably install the computer cooling fan, and can effectively fix it, which is suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6 A computer cooling fan that is easy to install includes a mainframe casing plate 1, an adjusting gear ring 3, a fixing plate 5, a holding spring 11, a mounting sleeve 8 and a cooling fan 2. The adjusting gear ring 3 is rotatably mounted on the inner side of the mainframe casing plate 1, and the fixing plate 5 is fixedly connected to the inner side of the mainframe casing plate 1. The fixing plate 5 is located inside the adjusting gear ring 3. A holding spring 11 is fixedly connected to an inner wall of one side of the fixing plate 5, and a movable ring 4 is fixedly connected to the end of the holding spring 11. The cooling fan 2 is installed inside the mounting sleeve 8, and the mounting sleeve 8 is located between the fixing plates 5. The circumferential outer wall of the mounting sleeve 8 is fixedly connected to the inner wall of the fixing plate 5. It is connected with connecting ears 9 distributed in a circular array, and a gear plate 6 is rotatably installed on the side of the fixing plate 5 away from the main casing plate 1, and the gear plate 6 is meshed with the tooth block on the inner wall of the adjusting gear ring 3, and a threaded rod 7 is threaded through the gear plate 6. The fixing plates 5 are arranged in a circular array, and the fixing plates 5 are matched with the connecting ears 9. The cross-section of the fixing plates 5 is arranged in a U-shaped structure, and the end of the connecting ear 9 is arranged in a semicircular structure. Positioning holes 10 are provided on the connecting ears 9 and the fixing plates 5, and the threaded rod 7 matches the positioning hole 10, and the main casing plate 1 is evenly provided with heat dissipation holes with the same structure.

[0025] Working principle: When the device needs to install the cooling fan 2, first, the connecting ear 9 on the circumferential side wall of the installation sleeve 8 is placed in an offset manner with the fixed plate 5, and then the installation sleeve 8 is pushed, so that the connecting ear 9 on the installation sleeve 8 pushes the movable ring 4, and the movable ring 4 squeezes and presses the spring 11, and then the installation sleeve 8 is rotated to drive the connecting ear 9 to rotate until the positioning hole 10 on the connecting ear 9 is aligned with the positioning hole 10 on the fixed plate 5, and then the adjusting toothed ring 3 is rotated to make the adjusting toothed ring 3 drive the gear plate 6 to rotate. Since the threaded rod 7 threads through the gear plate 6, the threaded rod 7 will be inserted into the positioning hole 10 when the gear plate 6 rotates, thereby completing the installation operation of the cooling fan 2.
