The unlocking plate 330 and the hinge plate 326 are respectively located at the front and rear opposite ends of the elastic locking plate 322. The unlocking plate 330 is formed with a locking slot 332. The locking plate 331 extends vertically downward from one side of the horizontal plate 327 and is between the hinge plate 326 and the unlocking plate 330, and is used to be locked in the corresponding locking slot 212 of the housing 2 (as shown in FIG. 3). The locking plate 331 has a rear inclined surface 333 facing backward. The rear bevel 333 is used for the front edge 211 of the housing 2 to contact and push, so that the buckle sheet 331 can pass over the front edge 211 and then buckle in the corresponding slot 212.

Referring to FIG8 and FIG9 , the elastic locking piece 322 can rotate between a locking position (as shown in FIG8 ) and an unlocking position (as shown in FIG9 ) relative to the back piece 323 of the fixing piece 321 through the hinge piece 326. In the locking position, the locking piece 331 is locked in the corresponding slot 212 of the housing 2. In the unlocking position, the locking piece 331 is separated from the corresponding slot 212 of the housing 2. The unlocking plate 330 is configured to be operated by being pulled so that the elastic locking plate 322 rotates relative to the fixing plate 321 through the hinge plate 326 to drive the locking plate 331 to disengage from the corresponding slot 212 of the housing 2, thereby releasing the locking state of the locking plate 331.

Referring to FIG. 5 , FIG. 6 and FIG. 7 , the operation cover 4 is made of plastic material and has a color different from that of the housing 31 of the housing 3 . The operation cover 4 is used to be sleeved on the unlocking piece 330 of the elastic locking piece 322 and includes a front end face 41 , a rear end face 42 , a bottom face 43 , an indication mark 44 , an inverted hook 45 , and a lower convex strip 46 . The rear end face 42 is opposite to the front end face 41 and is recessed forward to form a slot 47 for inserting the unlocking piece 330 . The indication mark 44 is formed on the front end face 41 to indicate the operation direction of the operation cover 4 and for the user to see.

The lower ridge 46 is protruding from the bottom surface 43 and adjacent to the front surface 41 for the user's finger to lift or pull.

Referring to Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the light guide 5 is made of a light-guiding material and includes two light guide rods 51, a front stop block 52, and a rear stop block 53. The light guide rods 51 are arranged at intervals along the second direction D2. Each of the light guide rods 51 is in a long column shape and its length extends along the first direction D1. The front and rear ends of each of the light guide rods 51 are respectively used to penetrate and engage with the corresponding front clamping hole 317 of the housing 31 and the corresponding rear clamping hole 325 of the fastener 32. The rear end of each of the light guide rods 51 is aligned with the corresponding light-emitting diode 12 to guide the light generated by the corresponding light-emitting diode 12 when it is in operation to the front panel 311. Thus, the user can clearly identify the working status of the corresponding storage device 1 by observing the luminous state of the light guide columns 51. The front stopper 52 is connected between the light guide columns 51 and is spaced from the front end of the light guide columns 51, and is used to stop at the back of the front panel 311 to limit the depth of the corresponding light guide column 51 penetrating the corresponding front clamping hole 317. The rear stopper 53 is connected between the light guide columns 51 and is spaced from the rear end of the light guide columns 51, and is used to stop at the front of the back sheet 323 to limit the depth of the corresponding light guide column 51 penetrating the corresponding rear clamping hole 325.

Referring to Figures 4, 5 and 6, the fasteners 6 are used to fixedly connect the side panels 313 of the housing 31 and the side sheet bodies 324 of the fastener 32. In this embodiment, each of the fasteners 6 is a riveted bolt, which is used to rivet the corresponding side panel 313 and the corresponding side sheet body 324 together.

Referring to Figures 2, 5, 6 and 7, the metal grounding springs 7 are respectively arranged on the top plate 312 and the side plates 313 of the housing 31. The corresponding metal grounding springs 7 arranged on the top plate 312 are used to abut against the top plate 22 of the housing 2. The corresponding metal grounding springs 7 arranged on the corresponding side plates 313 are used to abut against the corresponding side plates 23 of the housing 2, or the corresponding metal grounding springs 7 of the adjacent buckle device 300. In this way, the buckle device 300 can generate a good electromagnetic interference (EMI) shielding effect through the metal grounding springs 7.

Referring to FIGS. 4, 5, 6 and 7, when assembling the buckle device 300, the rear ends of the light guide columns 51 of the light guide member 5 are respectively passed through and engaged with the rear locking holes 325 of the locking member 32. Then, the assembled light guide member 5 and the locking member 32 are moved from the back to the front into the accommodating space 314 of the housing 31, so that the front ends of the light guide columns 51 of the light guide member 5 are respectively passed through and engaged with the front locking holes 317 of the housing 31, and the unlocking plate 330 of the locking member 32 is passed through the front opening 316 and protrudes from the front opening 316 for a distance. At this time, the light guide 5 is clamped by the housing 31 and the fastener 32, and the side pieces 324 are respectively located on the inner side of the side panels 313. Then, each of the fasteners 6 is riveted to the corresponding side panels 313 and the corresponding side pieces 324. After that, the metal grounding springs 7 are respectively assembled to the top panel 312 and the side panels 313 of the housing 31, and the assembly of the fastener device 300 is completed. After the fastener device 300 is assembled, it can be locked together with the housing 11 of the corresponding storage device 1 through the screws 10.

The following is a detailed description of the operation of the lock device 300 driving the corresponding storage device 1 to be withdrawn from the housing 2 and inserted into the housing 2: Referring to Figures 1, 7 and 8, when the lock device 300 and the corresponding storage device 1 are inserted into the accommodating space 24 of the housing 2, the storage device 1 is plugged into a circuit board (not shown) and electrically connected to the circuit board. The bottom end of the unlocking plate body 330 of the elastic lock plate 322 abuts against the lower stop surface 318 of the front panel 311 and is stopped by the lower stop surface 318, so that the elastic lock plate 322 is limited in the lock position. At this time, the locking plate 331 is locked in the corresponding slot 212, and the hinge plate 326 is in an undeformed state.

By designing the vents 315 of the front panel 311, the accommodating space 314 can exchange heat with the external environment of the buckle device 300 through the vents 315. Therefore, the heat energy generated by the storage device 1 during operation is discharged to the external environment through the vents 315 to achieve a good heat dissipation effect.

3 and 9 , when the user wants to remove the storage device 1 from the housing 2 through the buckle device 300 , the user first lifts the lower ridge 46 of the operating cover 4 upward along a lifting direction U by applying force with fingers. The operating cover 4 transmits the lifting force to the hinge plate 326 through the unlocking plate 330, the folded plate 329, the vertical plate 328 and the horizontal plate 327 of the elastic locking plate 322 to cause the hinge plate 326 to bend and deform under the force and accumulate the restoring elastic force, so that the operating cover 4 and the elastic locking plate 322 can rotate along a first rotation direction R1 relative to the back plate 323 of the fixing plate 321 through the hinge plate 326. During the rotation of the elastic locking plate 32, the locking plate 331 gradually moves away from the corresponding slot 212. When the unlocking plate 330 contacts the upper stop surface 319 of the front panel 311 and is stopped by the upper stop surface 319, the elastic locking plate 32 cannot continue to rotate and is limited to the unlocking position where the locking plate 331 is completely separated from the corresponding slot 212.

Next, the lower ridge 46 is pulled forward along a withdrawal direction M1 by fingers, and the locking device 300 can drive the storage device 1 to separate from the circuit board first and then be pulled out of the housing 2. Afterwards, the lower ridge 46 is released, and the elastic locking piece 322 is reset by the reset elastic force accumulated by the hinged piece 326, so that the elastic locking piece 322 can rotate along a second rotation direction R2 (as shown in FIG. 8) opposite to the first rotation direction R1 and automatically rebound to the locking position.

3 and 10 , when the user wants to insert the corresponding storage device 1 into the accommodating space 24 of the housing 2 through the buckle device 300, the front end surface 41 of the operating cover 4 is pushed backward along an insertion direction M2 opposite to the withdrawal direction M1, so that the buckle device 300 drives the corresponding storage device 1 to be inserted into the corresponding accommodating space 24 first. When the buckle device 300 moves to the point where the rear bevel 333 of the buckle sheet 331 of the elastic buckle sheet 322 contacts the front edge 211 of the bottom plate 21, the force exerted by the front edge 211 on the rear bevel 333 will push the buckle sheet 331 upward, and the force will be transmitted to the hinge sheet 326 through the buckle sheet 331 and the cross sheet 327 to cause the hinge sheet 326 to bend and deform under the force and accumulate restoring elastic force, thereby causing the elastic buckle sheet 322 to rotate relative to the back sheet 323 of the fixing sheet 321 along the first rotation direction R1 through the hinge sheet 326. Thereby, the buckle plate 331 can pass over the front edge 211 and move backward along the top surface of the bottom plate 21.

Referring to FIG. 8 , when the locking plate 331 of the elastic locking plate 322 moves to a position aligned with the corresponding slot 212, the elastic locking plate 322 is reset by the elastic restoring force accumulated by the hinge plate 326, so that the elastic locking plate 322 can rotate along the second rotation direction R2 and automatically rebound to the locking position where the locking plate 331 is locked in the corresponding slot 212. At this time, the storage device 1 is plugged back into the circuit board and electrically connected to the circuit board.

3, 8, 9 and 10, by designing the elastic locking piece 32 and the operating cover 4, the user only needs to lift the operating cover 4 along the lifting direction U to release the locking state of the elastic locking piece 32. Then, the user only needs to pull the operating cover 4 along the withdrawal direction M1 to withdraw the storage device 1 from the housing 2. By designing the rear bevel 333 of the locking plate 331, the user only needs to push the operating cover 4 backward along the insertion direction M2 to insert the storage device 1 into the housing 2 and make the locking device 300 automatically lock to the housing 2. In this way, the convenience and speed of the extraction and insertion operations can be improved.

Referring to Fig. 5, Fig. 6 and Fig. 7, the fastener 32 is an integrated single component and has the fastener sheet 331 and the unlocking sheet 330 at the same time, so that the fastener 32 has the function of fastening to the housing 2 and unlocking the housing 2 at the same time. In this way, the fastener device 300 does not need to cooperate with multiple components to achieve the above-mentioned functions, thereby reducing the number of components of the fastener device 300. Since the number of components of the fastener device 300 of this embodiment is small, it is convenient and easy to assemble. The assembled fastener device 300 has a simple structure, a small volume, and can reduce the space occupied, and can reduce the overall manufacturing cost of the fastener device 300.

By dividing the outer shell 3 into the shell cover 31 and the fastener 32, the shell cover 31 and the fastener 32 can respectively meet the requirements of having a strong structural strength and being flexible. In addition, the light guide 5 can be clamped and fixed by the shell cover 31 and the fastener 32, thereby simplifying the structural design of fixing the light guide 5. The lower stop surface 318 and the upper stop surface 319 of the shell cover 31 can not only limit the elastic fastener sheet 32 to the locking position and the unlocking position respectively, but also prevent the unlocking sheet body 330 from turning excessively.

The operation cover 4 provides the user with finger operation, which can protect the user's fingers and prevent them from being cut by the unlocking sheet 330 made of metal. The lower ridge 46 of the operation cover 4 facilitates the user's finger force operation, which can improve the convenience of operation. In addition, the operation cover 4 can display the operable part of the buckle device 300 through the color of the shell 31 different from the outer shell 3, so that the user can clearly identify it. Furthermore, through the indicator 44, the user can clearly and unambiguously know the operation method of the operation cover 4.

It should be noted that this embodiment can also have the following implementation forms according to needs: One of the implementation forms: the buckle device 300 omits the operation cover 4, so that the user can directly lift, pull or push the unlocking sheet 330.

Another embodiment: the housing 3 is an integrated single component and is made of a metal material with elasticity, wherein the back sheet 323 of the fastener 32 is integrally connected to the rear end of the top plate 312 or the rear end of the corresponding side plate 313.

In summary, the buckle device 300 of this embodiment has a small number of components, so it is convenient and easy to assemble. The assembled buckle device 300 has a simple structure, a small volume, and can reduce the space occupied, and can reduce the overall manufacturing cost of the buckle device 300. In addition, the buckle device 300 has fewer operating steps to drive the storage device 1 to be pulled out of the housing 2 and inserted into the housing 2, which can improve the convenience and speed of the pulling and inserting operations, so the purpose of the present invention can be achieved.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the patent of the present invention.
