Description

Technical Field

[0001] This utility model relates to the field of cooling fans, specifically a computer cooling fan. Background Technology

[0002] Computer cooling fans are key devices for cooling computers and their cases. Their core function is to help electronic components maintain a suitable operating temperature and ensure stable computer operation. These fans are mainly divided into case cooling fans and CPU cooling fans. When purchasing case cooling fans, it is necessary to match the size of the case to ensure stable cooling performance.

[0003] However, in existing technologies, some computer case cooling fans are fixedly installed to the case via a frame, and the frame size is mostly a fixed design. This limitation means that a specific type of case can only be matched with a cooling fan of the corresponding size. As a result, when users replace the case later, they must consider whether the size of the cooling fan is compatible. If the size does not match, the fan must be replaced as well, which not only increases the user's replacement cost but also reduces the practicality of the equipment. Therefore, a computer cooling fan is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a computer cooling fan.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a computer cooling fan includes a rectangular shell, an L-shaped sliding plate slidably connected to the inner wall of the rectangular shell, multiple sets of rectangular shells and L-shaped sliding plates are provided, and multiple sets of rectangular shells and L-shaped sliding plates are combined to form a frame, a sliding plate is fixedly connected to the side wall of the rectangular shell, a motor protective shell is provided on the inner side of the multiple sets of rectangular shells and L-shaped sliding plates, a drive shaft is rotatably connected to the inner wall of the motor protective shell, a cylindrical shell is sleeved on the outer wall of the drive shaft, heat dissipation blades are fixedly connected to the outer wall of the cylindrical shell, a fixed shell is fixedly connected to the outer wall of the motor protective shell, the outer wall of the sliding plate is slidably connected to the inner wall of the fixed shell, a circular plate is rotatably connected to the end side of the motor protective shell, a connecting plate is rotatably connected to the end side of the circular plate, a circular rod is fixedly connected to the side wall of the end of the sliding plate, and the other end of the connecting plate is rotatably connected to the outer wall of the circular rod.

[0006] Preferably, the inner wall of the motor protective housing is provided with a toothed groove, a pull rod is slidably connected to the inner wall of the circular plate, a gear is fixedly connected to the end of the pull rod, the gear is inserted into the inner wall of the toothed groove, a spring is sleeved on the outer wall of the pull rod, one end of the spring is fixedly connected to the inner wall of the circular plate, and the other end of the spring is fixedly connected to the end of the gear.

[0007] Preferably, the inner wall of the cylindrical shell is threaded with a bolt, the outer wall of the drive shaft is provided with a threaded hole, and the outer wall of the bolt end is threaded to the inner wall of the threaded hole.

[0008] Preferably, the L-shaped slide plate has a through hole on its side wall, and a damping pad is fixedly connected to the side wall of the L-shaped slide plate. The inner wall of the through hole is connected to the inner wall of the damping pad.

[0009] Preferably, the fixed shell, connecting plate, and sliding plate are provided in four sets, and the four sets of fixed shell, connecting plate, and sliding plate are arranged in a circular array with the center of the motor protective shell as the origin.

[0010] Preferably, the side wall of the fixed shell is provided with a through groove, and the outer wall of the round rod is specifically slidably connected to the inner wall of the through groove.

[0011] Preferably, the inner wall of the circular plate is provided with a toothed groove, and the outer wall of the gear is slidably connected to the inner wall of the toothed groove.

[0012] The advantages of this utility model are: by splicing multiple sets of rectangular shells and L-shaped sliding plates to form a frame, and through the cooperation between the fixed shell, round plate, pull rod, connecting plate and sliding plate, the size of the frame can be adjusted to ensure that the cooling fan can adapt to different models of chassis, thus improving practicality.

[0013] This invention uses a rotating circular plate to drive a connecting plate, which in turn drives a sliding plate to slide along the inner wall of a fixed shell via a circular rod. The rectangular shell also moves accordingly, thus changing the connection distance between the L-shaped sliding plate and the rectangular shell. This also changes the size of the frame formed by multiple rectangular shells and L-shaped sliding plates, achieving the effect of adjusting the size of the cooling fan frame. This solves the problem that when users replace their computer cases later, they must consider whether the cooling fan size is compatible—if the size does not match, the fan must be replaced as well, which not only increases the user's later replacement cost but also reduces the applicability of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail. This application discloses a computer cooling fan. (Refer to...) Figure 1 - Figure 4A computer cooling fan includes a rectangular shell 1. An L-shaped sliding plate 2 is slidably connected to the inner wall of the rectangular shell 1. Multiple sets of rectangular shells 1 and L-shaped sliding plates 2 are provided, and these sets combine to form a frame. A sliding plate 12 is fixed to the side wall of the rectangular shell 1. A motor protective shell 4 is provided inside the multiple sets of rectangular shells 1 and L-shaped sliding plates 2. A drive shaft 13 is rotatably connected to the inner wall of the motor protective shell 4. A cylindrical shell 5 is sleeved on the outer wall of the drive shaft 13. Cooling blades 6 are fixed to the outer wall of the cylindrical shell 5. A fixed shell 3 is fixed to the outer wall of the motor protective shell 4. The outer wall of the sliding plate 12 is slidably connected to the inner wall of the fixed shell 3. A circular plate 9 is rotatably connected to the end of the motor protective shell 4. A connecting plate 11 is rotatably connected to the end of the circular plate 9. A circular rod 16 is fixed to the side wall of the end of the sliding plate 12. The other end of the connecting plate 11 is rotatably connected to the outer wall of the circular rod 16. During operation, the frame of the cooling fan, formed by the combination of multiple sets of rectangular shells 1 and L-shaped sliding plates 2, ensures that the size of the frame can be adjusted. The adjustable design allows the cooling fan to be installed in different computer cases, improving practicality. When the frame size needs to be adjusted, the circular plate 9 can be rotated. The circular plate 9 will rotate with the connecting plate 11, changing the angle of the connecting plate 11. The other end of the connecting plate 11 will rotate with the circular rod 16, which in turn moves the sliding plate 12. The sliding plate 12 will move the rectangular shell 1. When the rectangular shell 1 moves, the connection distance between it and the L-shaped sliding plate 2 will change, and the size of the frame formed by multiple sets of rectangular shells 1 and L-shaped sliding plates 2 will also change accordingly. This allows the cooling fan to be installed inside different computer cases, solving the problem that users must consider the compatibility of the cooling fan size when changing cases later. If the size does not match, the fan must be replaced as well, which not only increases the user's later replacement cost but also reduces the applicability of the equipment.

[0019] Reference Figure 4 and Figure 6The inner wall of the motor protective housing 4 has a toothed groove 14. A pull rod 10 is slidably connected to the inner wall of the circular plate 9. A gear 19 is fixed to one end of the pull rod 10 and inserted into the inner wall of the toothed groove 14. A spring 20 is sleeved on the outer wall of the pull rod 10. One end of the spring 20 is fixed to the inner wall of the circular plate 9, and the other end is fixed to the end of the gear 19. During operation, by inserting the gear 19 into the inner wall of the toothed groove 14, the circular plate 9 can be limited at multiple angles. This ensures that the rectangular housing 1 and the L-shaped sliding plate are in contact. The two-piece frame allows for different sizes of efficiency, improving versatility. When the circular plate 9 needs to be rotated, the lever 10 can be pulled to move the gear 19. The gear 19 will compress the spring 20 and disengage from the inner wall of the toothed groove 14. At this time, the circular plate 9 can be pushed to rotate. After adjustment, simply release the lever 10. The spring 20 will push the gear 19 back to its original position through its elasticity, so that it inserts into the inner wall of the toothed groove 14 to limit the circular plate 9. This is quick, convenient, and improves practicality.

[0020] Reference Figure 3 and Figure 5 The inner wall of the cylindrical shell 5 is threaded with bolts 18, and the outer wall of the drive shaft 13 has a threaded hole 17. The outer wall of the end of the bolt 18 is threaded to the inner wall of the threaded hole 17. During operation, the cylindrical shell 5 is driven to rotate by the drive shaft 13. The rotating cylindrical shell 5 will drive the heat dissipation blades 6 to move and accelerate the airflow, thus achieving heat dissipation. The cylindrical shell 5 is installed on the outer wall of the drive shaft 13 by bolts 18. After the size of the cooling fan frame is adjusted, it can be disassembled and replaced to fit the size of the frame. When disassembling, simply use a tool to insert into the inner wall of the end of the bolt 18 to disengage it from the inner wall of the threaded hole 17, and then pull the cylindrical shell 5 to disengage it from the drive shaft 13. When installing, put the cylindrical shell 5 on the outer wall of the drive shaft 13 and then fix it with bolts 18.

[0021] Reference Figure 1 - Figure 3 The L-shaped slide plate 2 has a through hole 7 on its side wall, and a damping pad 8 is fixed to the side wall of the L-shaped slide plate 2. The inner wall of the through hole 7 is connected to the inner wall of the damping pad 8. During operation, the cooling fan can be fixed to the inner wall of the computer case through the through hole 7 to ensure its stability. The through hole 7 is in direct contact with the case, which can buffer the vibration generated by the cooling fan during use, thus improving its practicality.

[0022] Reference Figure 2 and Figure 4There are four sets of fixed shells 3, connecting plates 11, and sliding plates 12. The four sets of fixed shells 3, connecting plates 11, and sliding plates 12 are arranged in a circular array with the center of the motor protective shell 4 as the origin. During operation, the cooperation of the four sets of fixed shells 3, connecting plates 11, and sliding plates 12 can ensure that the size of the frame composed of multiple sets of rectangular shells 1 and L-shaped sliding plates 2 can be adjusted smoothly, thus improving practicality.

[0023] Reference Figure 4 The side wall of the fixed shell 3 is provided with a through groove 15. The outer wall of the round rod 16 is specifically slidably connected to the inner wall of the through groove 15. During operation, the through groove 15 ensures that the round rod 16 can move smoothly and stably in a straight line, thus improving its practicality.

[0024] Reference Figure 6 The inner wall of the circular plate 9 is provided with a toothed groove 21. The outer wall of the gear 19 is slidably connected to the inner wall of the toothed groove 21. During operation, the toothed groove 21 ensures that there is no relative rotation between the gear 19 and the circular plate 9, thus ensuring the stability of the gear 19 in limiting the circular plate 9.

[0025] Working principle: When the frame size needs to be adjusted, the lever 10 can be pulled to move the gear 19. The gear 19 will squeeze the spring 20 and disengage from the inner wall of the toothed groove 14. At this time, the circular plate 9 can be pushed to rotate. The circular plate 9 will rotate with the connecting plate 11, and the angle of the connecting plate 11 will change. The other end of the connecting plate 11 will rotate with the circular rod 16, and the circular rod 16 will drive the sliding plate 12 to move. The sliding plate 12 will drive the rectangular shell 1 to move. When the rectangular shell 1 moves, the connection distance between it and the L-shaped sliding plate 2 will change. After the frame size composed of multiple sets of rectangular shells 1 and L-shaped sliding plates 2 is adjusted, the lever 10 can be released directly. The spring 20 will push the gear 19 to reset through its own elasticity, so that it inserts into the inner wall of the toothed groove 14 to limit the circular plate 9.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
