Detailed Implementation
[0033] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0034] Please see Figures 1-8 This utility model provides a split USB flash drive, including a USB flash drive body 100 and a protective cover 200, and a connecting strap 10 connects the USB flash drive body 100 and the protective cover 200, so that when the USB flash drive body 100 is used, the protective cover 200 is not easy to fall off when it is pulled out from the top of the USB flash drive body 100.
[0035] The upper end of the USB flash drive body 100 is equipped with a locking element 300 for locking the protective cover 200, so that when the protective cover 200 is installed on the upper end of the USB flash drive body 100, the protective cover 200 is not easy to detach from the USB flash drive body 100.
[0036] The USB flash drive body 100 includes a housing 110 and two limiting boxes 120. The two limiting boxes 120 are respectively installed at the front and rear ends of the top of the housing 110. A cavity a is provided at the upper end of the housing 110 to house the limiting boxes 120, ensuring that the top surface of the limiting boxes 120 is level with the top surface of the stepped groove 111. Connecting blocks 121 are fixedly installed on the left and right sides of the limiting boxes 120. An internal hexagonal bolt 122 is installed in the middle of the connecting block 121, and the hexagonal bolt 122 is screwed into the helical groove in the cavity a, thereby fixing the limiting boxes 120 to the top of the housing 110. A magnetic block 123 is installed inside the limiting box 120.
[0037] The protective cover 200 includes a limiting plate 230 for limiting the protective cover 200 in conjunction with the limiting box 120. A plurality of L-shaped inserts 231 for limiting the protective cover 200 in conjunction with the locking member 300 are fixedly installed on one side of the limiting plate 230.
[0038] The locking member 300 includes a locking rod 310 for limiting the L-shaped insert 231, and a moving component 320 for controlling the left and right movement of the locking rod 310 is installed at one end of the locking rod 310.
[0039] The upper end of the housing 110 is provided with a stepped groove 111, the upper left side of the housing 110 is fixedly installed with a first limiting ring 112, the upper end of the housing 110 is provided with a plurality of positioning holes 113 for inserting L-shaped plug rods 231, and the upper right side of the housing 110 is provided with a limiting groove 114 for moving component 320 to move up and down.
[0040] The protective cover 200 includes a cover body 210. A second limiting ring 211 is fixedly installed on the lower left outer wall of the cover body 210, and one end of the connecting strap 10 is sleeved on the second limiting ring 211, while the other end of the connecting strap 10 is sleeved on the first limiting ring 112. A protruding ring 212 for engaging with the stepped groove 111 is fixedly installed at the bottom of the cover body 210. When the cover body 210 is installed on the housing 110, the protective cover 200 can be positioned by the protruding ring 212 engaging with the stepped groove 111, so that the L-shaped insert 231 and the positioning hole 113 can be aligned. Limiting blocks 220 for limiting the second limiting disc 230 are fixedly installed at both ends of the inner cavity of the cover body 210.
[0041] The limiting block 220 has a limiting cavity 221 inside for the limiting disc 230 to move up and down. The limiting cavity 221 has a sliding groove 222 on the left and right sides. A limiting rod 223 is installed in the middle of the groove 222. The lower end of the limiting rod 223 is fitted with a spring 224 for controlling the upward movement of the limiting disc 230. When the limiting disc 230 is pushed by the spring 224, the limiting disc 230 drives the L-shaped insert 231 to move towards the upper end of the limiting cavity 221 when the cover 210 moves away from the shell 110. This causes the L-shaped insert 231 to move into the inner cavity of the cover 210. When the protective cover 200 falls, the L-shaped insert 231 is not easily damaged by the impact.
[0042] A slot 232 is provided on one side of the L-shaped insert rod 231. Connecting blocks 233 that slide within the sliding groove 222 are fixedly installed on the left and right sides of the limiting plate 230. A cavity for the limiting rod 223 to slide is provided in the middle of the connecting blocks 233. A spring 224 is located at the lower end of the connecting blocks 233 so that the spring 224 can push the connecting blocks 233 upward, causing the connecting blocks 233 to drive the limiting plate 230 to move upward synchronously. The second limiting disk 230 is equipped with a second magnetic block 234 for magnetic attraction with the first magnetic block 123. When the cover 210 is installed on the upper end of the housing 110 and the protruding ring 212 is inserted into the stepped groove 111, the second magnetic block 234 and the first magnetic block 123 are magnetically attracted, which drives the second limiting disk 230 to move downward, so that the bottom of the second limiting disk 230 and the top of the first limiting box 120 are in contact, so that the protective cover 200 is at the upper end of the USB flash drive body 100.
[0043] The locking component 300 includes a locking rod 310 for limiting the L-shaped insert 231. The locking rod 310 has multiple slots 311 in its middle for the L-shaped insert 231 to be inserted. The L-shaped insert 231 moves towards the locking rod 310 through the positioning hole 113, and finally inserts into the cavity of the slot 311. A slanted groove 316 is machined on one side of the cavity of the slot 311. When the L-shaped insert 231 moves towards the locking rod 310... The bottom of the L-shaped insert 231 abuts against the inclined groove 316. As the L-shaped insert 231 continues to move downward, guided by the inclined groove 316, the L-shaped insert 231 is inserted into the cavity of the second slot 311. On the side of the second slot 311 where the inclined groove 316 is machined, a protrusion 317 that engages with the first slot 232 is installed. When the L-shaped insert 231 is inserted into the second slot 311, the protrusion 317 is inserted into the cavity of the first slot 232, thus locking the L-shaped insert 231.
[0044] A connecting rod 312 is fixedly installed on the right side of the locking rod 310. A second spring 315 for pushing the locking rod 310 to the left is sleeved on the left side of the connecting rod 312. A groove for limiting the second spring 315 is opened at the upper end of the housing 110, so that the second spring 315 always pushes the locking rod 310 to the left. With the setting of the second spring 315, when the L-shaped insert 231 is inserted into the groove of the second slot 311, the protrusion 317 is inserted into the first slot 232. A connecting plate 313 is fixedly installed on the right side of the connecting rod 312, and locking rods 310 are installed at both the front and rear ends of the connecting plate 313. A guide groove 314 is opened in the middle of the connecting plate 313.
[0045] The movable component 320 includes a pressing plate 321. Multiple anti-slip protrusions 322 are fixedly installed on the right side of the pressing plate 321 to increase friction when the pressing plate 321 is pushed downwards. A connecting block 323 is fixedly installed on the left side of the pressing plate 321. Connecting plates 324 are fixedly installed at both the upper and lower ends of the left side of the connecting block 323. A guide rod 325 is fixedly installed on the left side of the connecting plate 324 and is installed within a guide groove 314. A triangular block 326 is fixedly installed at the upper end of the guide rod 325 to cooperate with the guide groove 314 in controlling the locking lever 310 to move to the right. Because the spring 315 pushes the locking lever 310 to the left, the connecting plate 313 moves synchronously to the left, so that the connecting plate 313 is at the lower end of the guide rod 325, and the triangular block 326 is at the upper end of the guide groove 314.
[0046] When the USB flash drive body 100 is needed, first unlock the protective cover 200. Press and hold the press plate 321 and push it down. The press plate 321, together with the connecting block 323, drives the connecting plate 2 324 to move down, so that the guide rod 325 drives the triangular block 326 to move down. The triangular block 326 is gradually inserted into the guide groove 314. The hypotenuse of the triangular block 326 and the right wall of the guide groove 314 abut against each other, so that the connecting plate 1 313 moves to the right. Under the action of the connecting rod 312, the locking rod 310 moves to the right at the same time. At this time, the protrusion 317 moves away from the groove of the slot 1 232, and the lock on the L-shaped insert 231 can be released, so that the cover 210 can be removed from the upper end of the housing 110.
[0047] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
