[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0036] The present utility model embodiment provides a hard disk bracket 10, such as Figures 1 to 5 As shown, the hard disk bracket 10 includes a bracket body 1, a push-unlocking member 2, a rotation unlocking member 3, an unlocking driving member 4 and a locking tongue 5. The bracket body 1 includes a front shell 11 arranged at the front end of the bracket body 1, and the push-unlocking member 2 and the unlocking driving member 4 are installed side by side in the front shell 11.

[0037] One end of the push-unlocking member 2 close to the unlocking driving member 4 is rotatably connected to the front shell 11 and is engaged with the unlocking driving member 4. One end of the unlocking driving member 4 away from the push-unlocking member 2 is rotatably connected to the front shell 11. The lock tongue 5 can be telescopically mounted on the end of the front shell 11 away from the push-unlocking member 2 and is transmission-connected to the unlocking driving member 4. The rotating unlocking member 3 can be rotatably mounted on the push-unlocking member 2, and the rotating unlocking member 3 has an unlocking state and a locking state that can be switched to each other.

[0038] When the rotating unlocking member 3 is in the locked state, the pressing unlocking member 2 is away from the unlocking driving member 4 and cannot be pressed into the front shell 11 to release the clamping connection with the unlocking driving member 4. The unlocking driving member 4 is limited in the front shell 11, and the lock tongue 5 is in the extended locked state. When the rotating unlocking member 3 is rotated to the unlocking state, the end of the pressing unlocking member 2 away from the unlocking driving member 4 can be pressed into the front shell 11 to release the clamping connection with the unlocking driving member 4, and the unlocking driving member 4 pops out from the front shell 11 and drives the lock tongue 5 to retract and unlock.

[0039] The hard disk tray 10 of the utility model is provided with a push-unlocking member 2, a rotating unlocking member 3, an unlocking driving member 4, etc. in the front shell 11, wherein the rotating unlocking member 3 realizes unlocking of the push-unlocking member 2 by rotating, which is the initial unlocking of the hard disk tray 10, and the push-unlocking member 2 can be pressed after being unlocked. The end of the push-unlocking member 2 away from the unlocking driving member 4 is pressed to release the clamping connection with the unlocking driving member 4, and the unlocking driving member 4 pops out from the front shell 11 and drives the lock tongue 5 to retract and unlock, which is the secondary unlocking of the hard disk tray 10. By rotating the rotating unlocking member 3 to unlock and pressing the push-unlocking member 2 to unlock, the hard disk tray 10 is unlocked through two unlocking operations, which avoids the data security and equipment security problems caused by children or other operators easily unlocking the hard disk tray 10 and accidentally removing the hard disk, thereby improving the security of data or equipment.

[0040] Specifically, the bracket body 1 also includes a bracket 12 connected to the front shell 11, and the bracket 12 is used to install a hard disk. The hard disk can be, for example, a mechanical hard disk. A hard disk insertion space 100 is provided on the network attached storage device, and a lock slot corresponding to the lock tongue 5 is provided in the hard disk insertion space 100. The hard disk bracket 10 is inserted into the insertion space, and the lock tongue 5 is engaged with the lock slot to achieve the locking of the hard disk bracket 10. When unlocking, the hard disk bracket 10 is unlocked after the lock tongue 5 shrinks, and the hard disk can be taken out of the hard disk insertion space 100 at this time. After the unlocking drive 4 pops out from the front shell 11, it can also be used as a handle for the operator to pull the hard disk bracket 10 out of the hard disk insertion space 100.

[0041] Specifically, Figure 3 and Figure 5As shown, in the front shell 11, the end of the push-unlocking member 2 away from the unlocking drive member 4 is connected to a first elastic member 6 for driving the push-unlocking member 2 to reset. The first elastic member 6 provides the push-unlocking member 2 with a reset force after being pressed. The first elastic member 6 can be a spring. The end of the unlocking drive member 4 away from the push-unlocking member 2 is connected to a second elastic member 7 for driving the unlocking drive member 4 to pop out of the front shell 11. The second elastic member 7 provides the unlocking drive member 4 with a force to pop out of the front shell 11. The second elastic member 7 can be a spring or a torsion spring. When re-locking, the operator can press the popped-out unlocking drive member 4 back into the front shell 11. The push-unlocking member 2 and the unlocking drive member 4 can be rotatably installed in the front shell 11 via a rotating shaft 9. When the second elastic member 7 is a torsion spring, the torsion spring can be installed on the rotating shaft 9 on which the lock drive member is installed.

[0042] like Figures 2 to 5 As shown, a baffle 111 is provided in the front shell 11 corresponding to the rotation unlocking member 3, and an abutment portion 321 is provided on the rotation unlocking member 3. When the rotation unlocking member 3 is in the locked state, the abutment portion 321 is opposite to the baffle 111 to block the abutment portion 321 when the push unlocking member 2 is pressed. Figure 5 In the state shown), the abutment portion 321 is staggered with the baffle 111. In this solution, the locking and unlocking of the push unlocking member 2 by the rotation unlocking member 3 is realized by the cooperation between the baffle 111 and the abutment portion 321. Specifically, when the abutment portion 321 and the baffle 111 are in a relative state, when the rotation unlocking member 3 is pressed, the abutment portion 321 will abut on the baffle 111, and the rotation unlocking member 3 is in a locked state that cannot be pressed. The rotation unlocking member 3 is rotated so that the abutment portion 321 is staggered with the baffle 111. At this time, the baffle 111 can no longer block the abutment portion 321. When the rotation unlocking member 3 is pressed, it can rotate toward the inside of the front shell 11, thereby releasing the engagement with the unlocking drive member 4. The unlocking drive member 4 pops out under the elastic force of the second elastic member 7, and at the same time drives the lock tongue 5 to shrink and unlock.

[0043] Specifically, a clamping groove 22 is provided at one end of the push-unlocking member 2 close to the unlocking driving member 4, and a clamping protrusion 41 for clamping in the clamping groove 22 is provided at one end of the unlocking driving member 4 close to the push-unlocking member 2. When the push-unlocking member 2 is pressed into the interior of the front shell 11, the clamping groove 22 is rotated away from the clamping protrusion 41 due to the rotation of the end where the clamping groove 22 is located, thereby releasing the position limit of the clamping groove 22 on the clamping protrusion 41. After the position limit is released, under the elastic force of the second elastic member 7, the unlocking driving member 4 pops out from the front shell 11, and at the same time drives the lock tongue 5 to retract and unlock. A first inclined surface 411 can be provided on the side of the clamping protrusion 41 to facilitate the clamping protrusion 41 to be clamped into the clamping groove 22. In order to facilitate the engagement protrusion 41 to be engaged with the engagement slot 22, the unlocking member 2 can be pressed first to rotate the end where the engagement slot 22 is located to increase the activity space of the unlocking protrusion 41. After the unlocking driving member 4 is pressed back into the front shell 11, the unlocking member 2 can be released to reset the unlocking member 2. The engagement slot 22 presses the engagement protrusion 41 to lock the unlocking driving member 4. Of course, the engagement protrusion 41 can also be directly pressed into the engagement slot 22 when the width of the engagement protrusion 41 is set to a smaller width but sufficient to be stably engaged with the engagement slot 22.

[0044] Furthermore, inside the front shell 11, the lock tongue 5 is connected to a third elastic member 8 for driving the lock tongue 5 to extend and lock. Fig.10 As shown, a transmission insertion cavity 51 is provided on the lock tongue 5, and a transmission insertion portion 42 is provided at one end of the unlocking driving member 4 away from the pressing unlocking member 2, and the transmission insertion portion 42 is inserted into the transmission insertion cavity 51. When the unlocking driving member 4 pops out from the front shell 11, due to the rotation of the end where the transmission insertion portion 42 is located, the transmission insertion portion 42 will push the lock tongue 5 in the direction of the third elastic member 8, thereby realizing the contraction and unlocking of the lock tongue 5, and at this time, the third elastic member 8 is compressed and stored. After the unlocking driving member 4 is pressed back into the front shell 11, the clamping protrusion 41 is re-inserted into the clamping groove 22 to achieve position limiting. After the transmission insertion portion 42 releases the push on the lock tongue 5, the lock tongue 5 is re-extended under the elastic force of the third elastic member 8 to achieve locking. The lock tongue 5 can be provided with a locking portion 52 extending from the opening 112 on the front shell 11, and a second inclined surface 521 can be provided at the bottom of the locking portion 52 to facilitate the locking portion 52 to enter and exit the lock groove in the hard disk insertion space 100.

[0045] Specifically, Figures 6 to 9As shown, the push unlocking member 2 is provided with a first through hole 21, and the rotation unlocking member 3 can be rotatably installed in the first through hole 21. The rotation unlocking member 3 includes a rotating sub-member 31, and the peripheral surface of the rotating sub-member 31 is provided with a supporting convex edge 311; the inner wall of the first through hole 21 is provided with a resisting convex edge 211, and the supporting convex edge 311 is supported on the resisting convex edge 211. The resisting convex edge 211 cooperates with the supporting convex edge 311 to facilitate the installation of the rotating sub-member 31. A rotating groove 313 can be provided on the top of the rotating sub-member 31, and the operator can rotate the rotating sub-member 31 through the rotating groove 313 to achieve locking and unlocking of the rotation unlocking member 3.

[0046] Furthermore, a resisting protrusion 312 is provided on the circumferential surface of the rotating sub-component 31, and a notch area 212 is formed between the two ends of the resisting protrusion 211, and the resisting protrusion 312 is located in the notch area 212. When the rotating unlocking member 3 is rotated to the locked state, the resisting protrusion 312 resists one end of the resisting protrusion 211. When the rotating unlocking member 3 is rotated to the unlocked state, the resisting protrusion 312 resists the other end of the resisting protrusion 211. By resisting the resisting protrusion 312 and the two ends of the resisting protrusion 211, the rotation of the rotating unlocking member 3 can be limited within the rotation range of locking and unlocking, avoiding excessive rotation when locking or unlocking, and facilitating locking and unlocking.

[0047] Furthermore, the rotation unlocking member 3 further includes a mounting sub-member 32, and the abutting portion 321 is arranged at the bottom of the mounting sub-member 32; the mounting sub-member 32 is provided with a mounting insertion cavity 322, and one end of the rotating sub-member 31 away from the abutting convex edge 211 is inserted into the mounting insertion cavity 322. The mounting insertion cavity 322 can facilitate the assembly of the mounting sub-member 32 and the rotating sub-member 31, and can also improve the connection stability after the two are assembled. The mounting sub-member 32 and the rotating sub-member 31 can be connected by screws.

[0048] Two arc-shaped protrusions 323 are arranged opposite to each other on the peripheral wall of the mounting sub-component 32, and four arc-shaped grooves 213 with uniform intervals are arranged on the inner wall of the first through hole 21, and the central angle of the notch area 212 is 90°. When the rotary unlocking member 3 is rotated to the locked state, the two arc-shaped protrusions 323 are screwed into two of the opposite arc-shaped grooves 213; when the rotary unlocking member 3 is rotated to the unlocked state, the two arc-shaped protrusions 323 are screwed into the other two opposite arc-shaped grooves 213. The cooperation between the two arc-shaped protrusions 323 and the four evenly spaced arc-shaped grooves 213 can ensure that the rotary unlocking member 3 rotates stably, and the operator is prompted that the rotary unlocking member 3 has been locked or unlocked in place through the hand feeling when the arc-shaped protrusions 323 are embedded in the arc-shaped grooves 213. At the same time, the cooperation between the arc-shaped protrusions 323 and the arc-shaped grooves 213 can also position the rotary unlocking member 3.

[0049] Specifically, the arc groove 213 extends to the inner edge of the first through hole 21 . When the mounting component 32 is assembled into the first through hole 21 , the arc groove 213 extending to the inner edge of the first through hole 21 can guide the arc protrusion 323 .

[0050] like Fig.11 As shown, the utility model also discloses a network attached storage device, including the hard disk bracket 10 as described above. Since the network attached storage device includes the hard disk bracket 10 as described above, it also has the structure and technical effects of the hard disk bracket 10 as described above, which will not be described in detail here.

[0051] Specifically, the network attached storage device is provided with a hard disk insertion space 100, a lock slot corresponding to the lock tongue 5 is provided in the hard disk insertion space 100, and the hard disk bracket 10 is inserted in the insertion space, and the lock tongue 5 is engaged with the lock slot to realize the locking of the hard disk bracket 10. When unlocking, the lock tongue 5 shrinks, the hard disk bracket 10 is unlocked, and the hard disk can be taken out from the hard disk insertion space 100.

[0052] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it.
