Description

Technical Field

[0001] This utility model relates to the technical field of single-chip microcontroller fixing mechanisms, and in particular to a single-chip microcontroller fixing mechanism for a big data storage terminal. Background Technology

[0002] Big data storage terminals refer to hardware devices used for storing, managing, and processing massive amounts of data. With the rapid development of information technology, the amount of data is growing explosively. Traditional storage methods can no longer meet the needs of the big data era. Therefore, special storage devices are needed to assist in data management and storage. A single-chip microcontroller is a controller that integrates a microprocessor core, memory, input / output interfaces, and other peripheral devices on a single circuit board to control other devices or systems.

[0003] There are many ways to install existing single-chip microcontrollers, including screw fixing or countersunk studs, which install the controller inside the storage terminal chassis. After the controller is modified, it is connected to other devices through wires or other connectors via the interface pre-installed on the controller.

[0004] Existing single-chip microcontrollers are mainly installed using screws or other press-fit studs. However, after long-term use, single-chip microcontrollers need to be disassembled and repaired due to dust accumulation or internal circuit failure. The existing installation method can easily damage the circuit board and the inner wall of the chassis during disassembly and assembly, making it difficult to install securely later and causing inconvenience in use.

[0017] (III) Beneficial Effects

[0018] This utility model provides a fixing mechanism for a single-chip microcontroller in a big data storage terminal. It has the following beneficial effects:

[0019] 1. By squeezing the two insert plates, the insert plates are retracted into the fixed horizontal plate, thereby unlocking the rotating frames on both sides and the snap-fit ​​plate, and the limit rod is rotated open. After the controller is installed between the two insert plates, the rotating frames on both sides are rotated back to reset, causing the snap-fit ​​plate to snap and fix the controller at the four corners. The compression spring drives the insert plates and extension snap-fit ​​blocks to snap and lock the rotating frames, thus locking the rotating frames and finally installing the controller. This replaces the traditional pre-reserved riveting method for fixing, which is convenient for disassembly and disassembly will not damage the circuit board and the inner wall of the chassis.

[0020] 2.

Detailed Implementation

[0027] 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.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a fixing mechanism for a single-chip microcontroller 4 of a big data storage terminal, including a chassis 1, a fixing cover 2 fixedly installed on one side of the chassis 1, a heat sink 3 disposed between the chassis 1 and the fixing cover 2, a controller 4 disposed inside the chassis 1, and an installation component 5 disposed between the chassis 1 and the controller 4.

[0030] The mounting component 5 includes two fixed horizontal plates 501 fixedly installed inside the chassis 1. Several compression springs 503 are fixedly connected inside the fixed horizontal plates 501. An insert plate 502 is fixedly connected to one end of the compression spring 503 away from the fixed horizontal plates 501. Extension blocks 506 are fixedly connected to both ends of the insert plate 502. Two rotating frames 504 are hinged inside the chassis 1. Two snap-fit ​​plates 505 are provided inside the rotating frames 504.

[0031] Specifically, both ends of the fixed horizontal plate 501 are provided with rectangular openings that cooperate with the extension block 506. Through the cooperation of the rectangular openings and the extension block 506, the end of the snap-fit ​​plate 505 near the insert plate 502 is provided with a slot that cooperates with the insert plate 502. Both ends of the rotating frame 504 are provided with slots that cooperate with the extension block 506, thereby limiting the vertical movement of the insert plate 502 and keeping the insert plate 502 stable. In addition, the extension block 506 can protrude from the rectangular opening to facilitate snapping into the slot at one end of the rotating frame 504, thereby locking the rotating frame 504.

[0032] Specifically, a rectangular slot is provided on the side of the snap-fit ​​plate 505 away from the heat sink 3. The four corners of the controller 4 are snapped together through the rectangular slots on the outer surface of the four snap-fit ​​plates 505. After installation, the four corners of the controller 4 are respectively embedded in the corresponding rectangular slots of the controller 4, thereby realizing the installation.

[0033] Furthermore, by squeezing the two insert plates 502, the insert plates 502 are driven to retract into the fixed horizontal plate 501, thereby enabling the rotating frames 504 on both sides and the snap-fit ​​plate 505 to unlock and the limit rod to rotate open. After the controller 4 is installed between the two insert plates 502, the rotating frames 504 on both sides are rotated back to reset, causing the snap-fit ​​plate 505 to snap and fix the four corners of the controller 4. Then the insert plates 502 are unlocked, and the extension snap-fit ​​block 506 is driven by the insert plates 502 to snap and fix the rotating frame 504, thereby locking the rotating frame 504 and finally realizing the installation of the controller 4.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the rotating frame 504 is provided with an adjustment component 6 inside.

[0036] Adjustment component 6 includes a bidirectional threaded rod 602 movably installed inside the rotating frame 504. A threaded sleeve 606 is engaged with the outer surface of the bidirectional threaded rod 602. The outer surface of the threaded sleeve 606 is fixedly connected to the inside of the snap-fit ​​plate 505. A tension spring 605 is fixedly connected to the end of the threaded sleeve 606 away from the fixed cross plate 501.

[0037] Specifically, an arc-shaped guard plate 601 is fixedly connected inside the rotating frame 504. The arc-shaped guard plate 601 is installed on the side of the bidirectional threaded rod 602 away from the rotating frame 504. The inside of the snap-fit ​​plate 505 is provided with an arc-shaped through groove that cooperates with the arc-shaped guard plate 601. The outer surface of the snap-fit ​​plate 505 is provided with a limiting protrusion. The inside of the rotating frame 504 is provided with a limiting slide groove that cooperates with the limiting protrusion. The arc-shaped guard plate 601 provides protection and prevents the extension and contraction of the tension spring 605 from affecting the operation of the controller 4. Furthermore, the cooperation of the arc-shaped guard plate 601 and the limiting protrusion and limiting slide groove enables the movement of the limiting snap-fit ​​plate 505, preventing the snap-fit ​​plate 505 from rotating or misaligning.

[0038] Specifically, two fixing blocks 603 are fixedly connected in the middle of the rotating frame 504. The bidirectional threaded rod 602 passes through the interior of the two fixing blocks 603 in sequence. The end of the tension spring 605 away from the threaded sleeve 606 is fixedly connected to the outer surface of the fixing block 603. A nut 604 is fixedly connected between the two fixing blocks 603 on the outer surface of the bidirectional threaded rod 602. The fixing blocks 603 provide support for the bidirectional threaded rod 602, ensuring its stability. The tension spring 605 always maintains tension on the threaded sleeve 606, so that even if the bidirectional threaded rod 602 is slightly rotated due to vibration or other external forces, the tension spring 605 ensures that the threaded sleeve 606 can drive the snap-fit ​​plate 505 to maintain the clamping and fixing of the controller 4.

[0039] Furthermore, by turning the nut 604 with a wrench or other tools, the bidirectional threaded rod 602 is rotated, which in turn moves the threaded sleeve 606, causing the snap-fit ​​plate 505 to move. This allows for adjustment of the distance between the upper snap-fit ​​plate 505 and the lower snap-fit ​​plate 505, ensuring proper clamping and fixing of the circuit board, and finally completing the installation of the controller 4.

[0040] Working principle: When installing the controller 4 of the big data storage terminal, the insert plate 502 is pushed, causing it to retract into the fixed horizontal plate 501. By squeezing the two insert plates 502, the insert plates 502 are retracted into the fixed horizontal plate 501, thereby unlocking the rotating frames 504 on both sides and the snap-fit ​​plate 505, and the limit rod rotates open. After the controller 4 is installed between the two insert plates 502, the rotating frames 504 on both sides are rotated back to their original positions, causing the snap-fit ​​plate 505 to snap and fix the four corners of the controller 4. Then, the insert plates 502 are unlocked, and the extension snap-fit ​​block 506 is driven by the insert plates 502 to lock the rotating frame 504. The locking mechanism 504 is then connected, thereby enabling the installation of the controller 4. This replaces the traditional pre-riveting method for fixing, facilitating disassembly without damaging the circuit board or the inner wall of the chassis 1. Depending on the width of the circuit board, the nut 604 can be turned with a wrench or other tools, which will rotate the bidirectional threaded rod 602. This, in turn, will move the threaded sleeve 606, causing the snap-fit ​​plate 505 to move. This allows for adjustment of the distance between the upper and lower snap-fit ​​plates 505, ensuring proper clamping and fixing of the circuit board, and ultimately completing the installation of the controller 4.
