Description

Technical Field

[0001] This utility model relates to the field of flash drive technology, and in particular to a retractable flash drive. Background Technology

[0002] A flash drive is a miniature, high-capacity portable storage device that uses a USB interface and requires no physical drive. It connects to a computer via USB, enabling plug-and-play functionality. The main components of a flash drive include the casing, internal mechanism, controller chip, and flash memory chip. The flash drive operates based on flash memory technology, with its core being the EEPROM storage unit. After the flash drive connects to a computer via USB, the computer writes data to the flash memory chip for storage. The flash memory chip contains floating-gate transistors, which store data by controlling the gate voltage; the data is not lost when power is off.

[0003] An existing type of retractable flash drive is inconvenient for operators to control the connector on the flash drive for actual connection and fixation according to the actual usage of the flash drive. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a retractable flash drive.

[0005] This utility model is achieved by the following technical solution: a retractable flash drive, including a flash drive shell, a fixing ring fixedly connected to the rear end of the flash drive shell, and a connector fixedly connected to the front end of the flash drive shell;

[0006] The upper and lower ends of the flash drive casing are fixedly connected to mounting slide rails. A sliding support plate is slidably connected inside the mounting slide rails. A sliding outer shell is fixedly connected to the surface of the sliding support plate. A toggle plate is fixedly connected to the upper and lower ends of the sliding outer shell. A sealing plug is inserted into the front of the toggle plate. A handle is fixedly connected to the front of the sealing plug. A fixing sleeve is fixedly connected to the front of the mounting slide rail. A damping support is slidably connected inside the fixing sleeve.

[0007] With the above technical solution, two mounting rails are symmetrically distributed vertically. The surface of the sliding support plate contacts the flash drive shell. The dual rails guide the linear movement of the sliding shell, providing strong anti-tilt capability. The contact surface between the support plate and the shell is made of a low-friction coefficient material, reducing wear. The fixed hanging ring is fixed to the rear end of the flash drive shell. Combined with the compact size after retraction, it supports mounting or portable storage, avoiding the problem of traditional USB flash drives being easily lost. It is suitable for outdoor or mobile scenarios. The overall structure is compact, the telescopic mechanism is concealed, and the appearance is simple and beautiful.

[0008] As a further improvement to the above solution, the damping strut is fixedly connected to the rear end of the sliding housing, the sealing plug is located on the front of the connector, and the connector is located inside the sliding housing.

[0009] As a further improvement to the above solution, the number of mounting slide rails is set to two, and the two mounting slide rails are symmetrically distributed vertically around the flash drive casing, with the surface of the sliding support plate in contact with the surface of the flash drive casing.

[0010] Through the above technical solution, the sliding support plate slides along the mounting rail, driving the sliding housing to move back and forth, realizing the extension and retraction of the connector. In the retracted state, the connector is completely housed inside the sliding housing and sealed by the sealing plug, preventing dust and dirt. When extended, the connector is exposed for easy use, improving portability.

[0011] As a further improvement to the above solution, the inner surface of the sliding outer shell is slidably connected to the surface of the flash drive outer shell, and the number of the toggle plates is set to two, with the two toggle plates symmetrically distributed vertically around the sliding outer shell.

[0012] With the above technical solution, the toggle plate is fixed at both ends of the sliding housing. The user drives the toggle plate by pulling the handle, which moves the sliding housing along the slide rail. The handle provides a fulcrum for force application and is ergonomic. The extension and retraction operation can be completed with one hand. The toggle plate cooperates with the guide rail of the slide rail, ensuring smooth guidance and avoiding jamming.

[0013] As a further improvement to the above solution, the number of the fixed sleeve and damping support is set to two, and the two fixed sleeves and damping supports are symmetrically distributed vertically around the flash drive shell.

[0014] As a further improvement to the above solution, the fixed sleeve and damping support are located at the upper and lower ends of the flash drive casing, and the sliding casing is located on the front of the mounting rail.

[0015] As a further improvement to the above solution, the number of sliding support plates is set to two, and the two sliding support plates are symmetrically distributed on the left and right sides with the sliding shell as the center.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model features two symmetrically distributed mounting rails. The surface of the sliding support plate contacts the flash drive casing, and the dual rails ensure linear movement of the sliding casing, providing strong resistance to tilting. The contact surface between the support plate and the casing is made of a low-friction coefficient material to reduce wear. The fixed lifting ring is attached to the rear end of the flash drive casing, and its compact size after retraction allows for mounting or portable storage. The telescopic structure saves space and protects the interface, while the damping system enhances impact resistance. The sealed design is suitable for dusty and humid environments.

[0018] This invention features a sealing plug inserted into a toggle plate. As the sliding shell moves, the plug covers or exposes the connector. In the retracted state, the sealing plug tightly adheres to the connector surface, preventing dust and liquid splashes. The material is elastic rubber or silicone, which is wear-resistant and provides a reliable seal. The sliding shell offers double-layer protection. The inner part of the sliding shell is slidably connected to the surface of the flash drive shell, forming a double-nested structure. The outer layer protects against physical impacts, while the inner sealing plug protects the interface. The gap design between the sliding shell and the flash drive shell prevents foreign objects from being trapped. Attached Figure Description
