Description

Technical Field

[0001] This utility model relates to the technical field of memory card insertion and removal mechanisms, and in particular to a high-speed memory card insertion and removal mechanism with anti-card removal self-locking mechanism. Background Technology

[0002] With the rapid development of embedded devices, industrial control, automotive electronics, aerial photography and outdoor imaging equipment, high-speed memory cards are needed for installation, fixing, insertion and removal, and data reading and writing.

[0003] In practical use, high-speed memory cards with similar structures still have many defects, such as: traditional high-speed memory card insertion and removal mechanisms are prone to loosening and falling off under vibration and shaking, resulting in poor contact, read and write interruption, or even data loss. At the same time, traditional high-speed memory cards lack protection against accidental touch, and the memory card is prone to automatically ejecting due to accidental pressing. In addition, the insertion and removal operation is not convenient and requires auxiliary tools. Therefore, it is necessary to design a self-locking high-speed memory card insertion and removal mechanism that prevents card detachment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a self-locking high-speed memory card insertion and removal mechanism to prevent card detachment.

[0005] This utility model is achieved by the following technical solution: a self-locking high-speed memory card insertion and removal mechanism for preventing card detachment, including a positioning component, the positioning component including a device body, a high-speed memory card being inserted into the inside of the device body, a positioning plate being provided on the outer surface of the high-speed memory card by a positioning frame, and further including;

[0006] A limiting assembly, the limiting assembly including a locking seat that is slidably mounted inside the device body via a first spring damper, and a protrusion is fixedly connected to one side of the locking seat;

[0007] A buffer assembly includes a buffer plate that is slidably mounted inside the device body via a second spring damper. A high-speed memory card is inserted into the outer surface of the buffer plate via a limiting seat. A fixing seat matching a locking seat is provided on the side of the outer surface of the buffer plate away from the limiting seat.

[0008] As a further improvement to the above solution, a mounting rod is fixedly connected to the outer surface of the device body, a positioning frame is fixedly connected to the outer surface of the mounting rod, and a threaded sleeve is fixedly connected to the inside of the positioning frame.

[0009] The above technical solution, through the structural arrangement of mounting rod, positioning frame and threaded sleeve, provides a stable installation foundation for the external limiting mechanism, so that the positioning component can be reliably fixed on the outside of the equipment body, which facilitates the subsequent limiting protection of the memory card and improves the assembly stability and positioning reliability of the overall structure.

[0010] As a further improvement to the above solution, a positioning plate is rotatably connected inside the positioning frame, and a positioning bolt is threaded inside the positioning plate. The bottom thread of the positioning bolt is threaded into the inside of the threaded sleeve, and the positioning plate and the positioning frame are fixedly connected by the positioning bolt.

[0011] The above technical solution, through the cooperation of positioning plate, positioning bolt and threaded sleeve, can realize external clamping and positioning of memory card, effectively prevent memory card from being accidentally pressed and mis-locked, further enhance the anti-disengagement effect, and the disassembly and assembly method is simple, which makes it easy to quickly realize the limit and release the limit.

[0012] As a further improvement to the above solution, the device body has an internal movable groove, a first limiting groove is provided at the center of the movable groove, an embedded seat is fixedly connected to the inner wall of the movable groove on one side of the first limiting groove, and second limiting grooves are provided on both sides of the movable groove.

[0013] By using the above technical solution, by opening a movable groove, a first limiting groove, a second limiting groove and setting an embedded seat in the device body, a standardized running track is provided for the internal sliding parts, so that the movement trajectory of each part is precise and controllable, avoiding deviation and jamming, and ensuring that the self-locking and unlocking actions are completed smoothly.

[0014] As a further improvement to the above solution, a first spring damper is fixedly connected to the inner wall of the movable groove. The first spring damper is slidably installed inside the first limiting groove. A locking seat is fixedly connected to the top of the first spring damper. A locking groove is provided between the locking seat and the protrusion.

[0015] Through the above technical solution, the automatic elastic self-locking of the memory card after insertion is achieved by the cooperation of the first spring damper, locking seat, locking groove and protrusion. The card can be locked and fixed without additional operation, ensuring that the memory card is firmly connected and not easily loosened in the vibrating environment, thus improving the stability of use.

[0016] As a further improvement to the above solution, a second spring damper is fixedly connected to the inner wall of the movable groove on one side of the embedded seat, and a buffer plate is fixedly connected to the front end of the second spring damper. The buffer plate is slidably installed inside the second limiting groove.

[0017] The above technical solution provides elastic buffering and reset thrust for the memory card by sliding the second spring damper and the buffer plate in the second limiting groove, making the insertion and removal action smoother. At the same time, the memory card can be automatically pushed outward when unlocking, improving the convenience of insertion and removal operations.

[0018] As a further improvement to the above solution, a fixing seat is fixedly connected to the side of the outer surface of the buffer plate away from the limiting seat. The fixing seat matches the locking groove. An embedding block is fixedly connected to the outer surface of the buffer plate on one side of the fixing seat. The embedding block is inserted into the interior of the embedding seat.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes the combined operation of a buffer plate, a limiting seat, a locking seat, a spring damper, a protruding block, and a fixed seat to achieve an automatic locking effect after the memory card is inserted. This ensures a secure connection between the memory card and the device, preventing it from loosening or falling off. The embedding block and the embedding seat work together to provide auxiliary limiting, further enhancing structural stability and preventing poor contact of the memory card. This provides a reliable guarantee for high-speed reading and writing, allowing the memory card to work stably in vibration environments and effectively improving the reliability and safety of the storage device.

[0021] This utility model utilizes the coordinated operation of a positioning frame, positioning plate, positioning bolt, and threaded sleeve to achieve an external limiting and anti-accidental unlocking effect for the memory card. This ensures that the memory card will not be accidentally released due to external force after being locked. At the same time, it adopts a press-to-lock and press-again-release unlocking method, making disassembly and assembly simple and quick without the need for additional tools. This not only improves the convenience of inserting and removing the memory card but also further strengthens the anti-dislodgement protection, making the overall use more efficient and safer.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a self-locking high-speed memory card insertion and removal mechanism for preventing card detachment includes a positioning component 1. The positioning component 1 includes a device body 101. A high-speed memory card 102 is inserted into the device body 101. A positioning plate 106 is provided on the outer surface of the high-speed memory card 102 through a positioning frame 104. The mechanism also includes:

[0032] Limiting component 2 includes a locking seat 205 that is slidably installed inside the device body 101 via a first spring damper 204, and a protrusion 207 is fixedly connected to one side of the locking seat 205.

[0033] The buffer assembly 3 includes a buffer plate 302 that is slidably installed inside the device body 101 via a second spring damper 301. A high-speed memory card 102 is inserted into the outer surface of the buffer plate 302 via a limiting seat 303. A fixing seat 304 that matches the locking seat 205 is provided on the side of the outer surface of the buffer plate 302 away from the limiting seat 303.

[0034] An installation rod 103 is fixedly connected to the outer surface of the equipment body 101, a positioning frame 104 is fixedly connected to the outer surface of the installation rod 103, and a threaded sleeve 105 is fixedly connected to the inside of the positioning frame 104.

[0035] The positioning frame 104 is rotatably connected to a positioning plate 106, and the positioning plate 106 is threadedly connected to a positioning bolt 107. The bottom of the positioning bolt 107 is threadedly connected to the inside of the threaded sleeve 105. The positioning plate 106 and the positioning frame 104 are fixedly connected by the positioning bolt 107.

[0036] The device body 101 has an internal movable groove 201. A first limiting groove 202 is provided at the center of the movable groove 201. An embedded seat 208 is fixedly connected to the inner wall of the movable groove 201 on one side of the first limiting groove 202. Second limiting grooves 203 are provided on both sides of the movable groove 201.

[0037] A first spring damper 204 is fixedly connected to the inner wall of the movable groove 201. The first spring damper 204 is slidably installed inside the first limiting groove 202. A locking seat 205 is fixedly connected to the top of the first spring damper 204. A locking groove 206 is provided between the locking seat 205 and the protrusion 207.

[0038] A second spring damper 301 is fixedly connected to the inner wall of the movable groove 201 on one side of the embedded seat 208. A buffer plate 302 is fixedly connected to the front end of the second spring damper 301. The buffer plate 302 is slidably installed inside the second limiting groove 203.

[0039] A fixing seat 304 is fixedly connected to the side of the outer surface of the buffer plate 302 away from the limiting seat 303. The fixing seat 304 matches the locking groove 206. An embedding block 305 is fixedly connected to the outer surface of the buffer plate 302 on one side of the fixing seat 304. The embedding block 305 is inserted into the interior of the embedding seat 208.

[0040] When the high-speed memory card 102 needs to be removed, first unscrew the positioning bolt 107 from the inside of the threaded sleeve 105 and the positioning plate 106 to release the constraint of the positioning plate 106 on the high-speed memory card 102. Then press the high-speed memory card 102 inward. The high-speed memory card 102 drives the buffer plate 302 to continue to retract through the limit seat 303. The fixed seat 304 squeezes the protrusion 207 and pushes the locking seat 205 to compress the first spring damper 204, so that the fixed seat 304 is released from the constraint of the locking groove 206. At this time, under the rebound action of the second spring damper 301, the buffer plate 302 drives the high-speed memory card 102 to pop outward.

[0041] The implementation principle of the anti-dislodgement self-locking high-speed memory card insertion and removal mechanism in this embodiment is as follows: By inserting the high-speed memory card 102 into the device body 101, the high-speed memory card 102 directly inserts into the limiting seat 303 on the surface of the buffer plate 302. As the high-speed memory card 102 continues to push inward, it causes the buffer plate 302 to slide and retract along the second limiting groove 203 within the movable groove 201 inside the device body 101. Simultaneously, the movement of the buffer plate 302 causes the fixed seat 304 on its surface to move synchronously. The fixed seat 304 first contacts and presses against the locking seat 205, causing the locking seat 205 to slide within the first limiting groove 202 and compress the first spring damper 204. Once the high-speed memory card 102 is fully inserted... The first spring damper 204 pushes the locking seat 205 to reset by its own elasticity, so that the fixed seat 304 is inserted into the locking groove 206 between the locking seat 205 and the protrusion 207, forming a mutual locking. At the same time, the embedded block 305 on the surface of the buffer plate 302 is inserted into the embedded seat 208 for auxiliary limiting. The second spring damper 301 continuously applies an outward pushing force to the buffer plate 302, so that the fixed seat 304 and the locking groove 206 are kept in close contact. This operation mode can automatically achieve self-locking after the high-speed memory card 102 is inserted, avoiding loosening, falling off or poor contact during use, ensuring a stable connection between the high-speed memory card 102 and the device body 101, and providing a reliable structural foundation for high-speed reading and writing.

[0042] By rotating the positioning plate 106 inside the positioning bracket 104, it is made to adhere to the surface of the high-speed memory card 102. Then, the positioning bolt 107 is threaded into the positioning plate 106 and the threaded sleeve 105, fixing the positioning plate 106 and the positioning bracket 104 as one unit. This externally limits the high-speed memory card 102, preventing accidental unlocking caused by external force. When it is necessary to remove the high-speed memory card 102, first unscrew the positioning bolt 107 from the threaded sleeve 105 and the positioning plate 106 to release the constraint of the positioning plate 106 on the high-speed memory card 102, and then press the high-speed memory card 102 inward. Card 102 continues to retract via limit seat 303, causing buffer plate 302 to retract. Fixed seat 304 squeezes protrusion 207 and pushes locking seat 205 to compress first spring damper 204, causing fixed seat 304 to disengage from locking groove 206. At this time, under the rebound action of second spring damper 301, buffer plate 302 drives high-speed memory card 102 to pop out, so that high-speed memory card 102 can be easily removed from inside device body 101. This operation mode realizes the convenient operation of pressing to lock and pressing again to unlock. At the same time, the external positioning structure further improves the anti-dislodgement effect, ensuring safety in use and making the disassembly and assembly process more efficient and convenient.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
