Description

Technical Field

[0001] This utility model relates to the field of fixing buckle technology, specifically to a fixing buckle for a cooling fan base. Background Technology

[0002] During the operation of electronic devices, heat dissipation is a key factor in ensuring their stability and extending their service life. Cooling fans, as common heat dissipation devices, are widely used in various electronic devices, such as computer hosts, servers, and industrial control equipment. The cooling fan base fixing clip is an important component that ensures that the cooling fan can be firmly installed inside the equipment to achieve efficient heat dissipation.

[0003] In the field of electronic device heat dissipation, negative pressure cooling fans are widely used due to their high-efficiency heat dissipation performance. However, during the installation of cooling fans, it is difficult to quickly and accurately place the fan in the appropriate position. Installers often need to spend a lot of time making repeated adjustments to ensure that the fan is installed in place. This not only reduces installation efficiency but also increases the difficulty and error rate of installation. On the other hand, during equipment operation, due to factors such as vibration, the fan is prone to loosening or displacement, resulting in a decrease in heat dissipation effect and even potentially causing equipment failure, affecting the normal operation and service life of the equipment. Therefore, those skilled in the art provide a cooling fan base fixing clip to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing clip for a cooling fan base, thereby solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a cooling fan base fixing buckle, including a base body and two sets of negative pressure cooling fans. The upper top of the base body has two mounting positions, and the two negative pressure cooling fans are respectively located in the two mounting positions. The upper top of the base body is provided with two first filter plates above the negative pressure cooling fans. Each first filter plate has a side plate fixedly connected to the center of both sides of its outer wall. The upper top of each side plate is threaded with a limit pin, and the end of the limit pin is threaded to the base body. Two sets of buckle mechanisms for limiting the negative pressure cooling fans are symmetrically arranged on both sides of the outer wall of the base body.

[0006] Preferably, the negative pressure cooling fan has symmetrically provided limit slots on both sides of its outer wall, and a second filter plate is fixedly connected to the lower top of the negative pressure cooling fan. The lower top of the negative pressure cooling fan is parallel to the lower bottom of the base body.

[0007] Preferably, the base body has two guide frames symmetrically fixedly connected on both sides of each mounting position, and each negative pressure cooling fan is slidably sleeved on the outer wall of each guide frame.

[0008] Preferably, each set of the buckling mechanism includes symmetrically opened inner grooves inside the base body, and a fixing rod is slidably connected inside each inner groove. The ends of the two fixing rods are jointly fixedly connected to a connecting plate. The connecting plate is located in the installation position, and a limiting rack that engages with the limiting groove is symmetrically fixedly connected to the side of the connecting plate away from the fixing rod.

[0009] Preferably, the ends of the two fixing rods away from the connecting plate are fixedly connected to a pull plate, and a fixing plate is fixedly connected to the outer wall of each fixing rod. The fixing plate is slidably sleeved inside the inner groove. A limit spring is fixedly connected to the side of the fixing rod away from the connecting plate, and the limit spring is fixedly connected to the inner side wall of the inner groove.

[0010] Preferably, each of the pull plates is symmetrically and fixedly connected to a fixed bracket on one side of the base body that is close to each other, and a connecting frame is rotatably sleeved inside each fixed bracket. Two connecting frames are rotatably sleeved at one end that is close to each other, and a bidirectional bracket is fixedly connected to the lower top of each fixed bracket to prevent the connecting frame from rotating excessively.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model features four sets of latching mechanisms, with each pair of sets limiting the positions of a single negative pressure cooling fan on both sides. During installation, simply pull the pull plate to move the connecting plate backward, allowing the connecting plate and limiting rack to fully enter the base body without obstructing the installation of the negative pressure cooling fan. During this process, the angle between the fixed bracket and the connecting bracket gradually changes from an inclined state to a parallel state. Since the bottom plate of the fixed bracket is sealed, the connecting bracket will not rotate further, with a limited rotation angle. The pull plate remains stationary due to the contact between the connecting bracket and the bidirectional bracket against the outer wall of the base body. Even without applying any pulling force, the pull plate will not move, allowing the negative pressure cooling fan to be easily placed in the installation position. Then, applying an upward pushing force to the bidirectional bracket causes it to reset under the action of the limiting spring, completing the installation of the negative pressure cooling fan.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figures 1-4 As shown, this utility model provides a technical solution: a cooling fan base fixing buckle, including a base body 1 and two sets of negative pressure cooling fans 5. The upper top of the base body 1 has two mounting positions, and the two negative pressure cooling fans 5 are respectively located in the two mounting positions. The upper top of the base body 1 is provided with two first filter plates 2 above the negative pressure cooling fans 5. Each first filter plate 2 has a side plate 21 fixedly connected to the center of both sides of its outer wall. The upper top of each side plate 21 is threaded with a limit pin 4, and the end of the limit pin 4 is threaded to the base body 1. Two sets of buckle mechanisms 3 for limiting the negative pressure cooling fans 5 are symmetrically arranged on both sides of the outer wall of the base body 1.

[0016] It should be noted that the base body 1 has two mounting positions, which can securely install two sets of negative pressure cooling fans 5 to enhance heat dissipation capacity and meet the high heat dissipation requirements of the equipment. A first filter plate 2 is set above the negative pressure cooling fan 5, which can effectively block dust and other impurities from entering the fan, reduce dust wear on the fan, extend the fan's service life, and ensure stable heat dissipation. The side plates 21 on both sides of the first filter plate 2 cooperate with the limiting pins 4, and the limiting pins 4 are threadedly connected to the base body 1, which can easily and quickly install and remove the first filter plate 2, facilitate regular cleaning of dust on the filter plate, and maintain good filtration performance. Two sets of buckle mechanisms 3 are symmetrically set on both sides of the outer wall of the base body 1 to limit the negative pressure cooling fan 5, which can ensure that the fan remains stable during operation and will not shift or loosen due to vibration, avoid noise caused by fan instability, and at the same time ensure the reliability of the connection between the fan and the base body 1, improving the stability and reliability of the entire heat dissipation system.

[0017] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, the negative pressure cooling fan 5 has symmetrically opened limit slots 51 on both sides of its outer wall. The lower top of the negative pressure cooling fan 5 is fixedly connected to a second filter plate 6. The lower top of the negative pressure cooling fan 5 is parallel to the lower bottom of the base body 1. The interior of the base body 1 has two guide frames 7 symmetrically fixedly connected on both sides of each installation position. Each negative pressure cooling fan 5 is slidably sleeved on the outer wall of each guide frame 7.

[0018] It should be noted that the symmetrically designed limiting slots 51 on both sides of the outer wall can cooperate with the corresponding structure on the base to play a precise positioning role during installation, allowing the negative pressure cooling fan 5 to be placed quickly and accurately in the installation position. At the same time, it enhances the stability of the fan after installation, prevents it from swaying left and right, and ensures smooth operation. The second filter plate 6 fixed at the bottom top can further intercept dust and other impurities, forming a double protection with the first filter plate, which greatly improves the dustproof effect, effectively prevents dust from entering the fan and damaging the motor and other components, and extends the service life of the fan. The two guide frames 7 symmetrically fixed on both sides of the installation position inside the base body 1 have the negative pressure cooling fan 5 slidingly fitted on its outer wall. When installing and removing the fan, the guide frames 7 can play a guiding role, making the operation smoother and more convenient.

[0019] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, each set of buckling mechanisms 3 includes an inner groove 31 symmetrically opened inside the base body 1. A fixing rod 32 is slidably connected inside each inner groove 31. The ends of the two fixing rods 32 are fixedly connected to a connecting plate 34. The connecting plate 34 is located in the installation position. A limiting rack 35 that engages with the limiting groove 51 is symmetrically fixedly connected to the side of the connecting plate 34 away from the fixing rod 32.

[0020] It should be noted that the inner groove 31 is symmetrically opened inside the base body 1, providing a stable sliding space for the fixing rod 32, making the movement of the fixing rod 32 more precise and smooth, without any deviation or jamming. The fixing rod 32 can slide flexibly in the inner groove 31, and its position can be adjusted according to actual needs, thereby driving the connecting plate 34 to move, realizing flexible limiting operation of the negative pressure cooling fan 5. The ends of the two fixing rods 32 are jointly fixed to the connecting plate 34, which enhances the stability of the structure, so that the connecting plate 34 can remain stable under force and is not easily deformed. The connecting plate 34 is located in the installation position and can directly act on the negative pressure cooling fan 5, ensuring the effective performance of the limiting function. The limiting rack 35 symmetrically fixed on the side of the connecting plate 34 away from the fixing rod 32 can engage with the limiting slots 51 on both sides of the outer wall of the negative pressure cooling fan 5. This tight engagement method can firmly fix the negative pressure cooling fan 5 in the installation position, effectively preventing the fan from loosening or falling off due to vibration during operation.

[0021] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, the ends of the two fixed rods 32 away from the connecting plate 34 are fixedly connected to a pull plate 33. The outer wall of each fixed rod 32 is fixedly connected to a fixed plate 36, and the fixed plate 36 is slidably sleeved inside the inner groove 31. The side of the fixed rod 32 away from the connecting plate 34 is fixedly connected to a limit spring 37, and the limit spring 37 is fixedly connected to the inner side wall of the inner groove 31. Each pull plate 33 is symmetrically fixedly connected to a fixed bracket 38 on the side close to the base body 1. Each fixed bracket 38 is rotatably sleeved with a connecting frame 382. The ends of the two connecting frames 382 that are close to each other are rotatably sleeved with a bidirectional bracket 39. The bottom top of each fixed bracket 38 is fixedly connected to a base plate 381 to prevent the connecting frame 382 from rotating excessively.

[0022] It should be noted that the pull plate 33 connects two fixed rods 32, allowing the operator to pull both fixed rods 32 simultaneously, saving time and effort, and enabling quick unlocking of the negative pressure cooling fan 5. The fixed plate 36 slides within the inner groove 31, preventing the fixed rods 32 from shifting during sliding, ensuring their linear movement and improving the stability of the latching mechanism 3. The limiting spring 37 connects the fixed rods 32 to the inner wall of the inner groove 31. When the pull plate 33 is pulled, the limiting spring 37 is stretched and automatically rebounds after being released, causing the connecting plate 34 and the limiting rack 35 to quickly reset, achieving automatic locking of the negative pressure cooling fan 5. The operation is convenient and efficient. The fixed bracket 38, connecting bracket 382, ​​and bidirectional bracket 39 work together to further enhance the connection stability between the pull plate 33 and the base body 1, making the pulling action smoother. The base plate 381 prevents the connecting bracket 382 from rotating excessively, avoiding structural damage and extending the service life of the latching mechanism 3.

[0023] Working principle: By setting four sets of buckling mechanisms 3, each pair of sets limits the two sides of a single negative pressure cooling fan 5. During installation, pulling the pull plate 33 causes the fixing rod 32 to slide in the inner groove 31, causing the connecting plate 34 to move backward. The limiting rack 35 then enters the base body 1, without obstructing the installation of the negative pressure cooling fan 5. During this process, the angle between the fixing bracket 38 and the connecting bracket 382 changes from tilted to nearly parallel. Because the bottom plate 381 at the bottom of the fixing bracket 38 is sealed, the rotation angle of the connecting bracket 382 is limited. Then, the connecting bracket 382 and the bidirectional bracket 39 abut against the outer wall of the base body 1. Even without applying a pulling force, the pull plate 33 can remain stationary. At this point, the negative pressure cooling fan 5 is placed into the installation position along the guide frame 7. The second filter plate 6 at its lower top can assist in dust prevention, and the lower top is parallel to the lower bottom of the base body 1, which is conducive to layout. Then, an upward push is applied to the bidirectional bracket 39. Under the action of the limiting spring 37, the fixing rod 32 drives the connecting plate 34 to reset. The limiting rack 35 engages with the limiting slot 51 to complete the installation. At the same time, the first filter plate 2 is fixed above the negative pressure cooling fan 5 via the side plate 21 and the limiting pin 4 to further prevent dust and ensure the stable operation of the cooling fan.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
