In this way, the external air is only drawn into the network attached storage from the air inlet, and the fan 7 mainly blows air to the main air duct 80 and the main control circuit board 82 air duct, and finally, the air can be blown out from the gaps around the network attached storage to achieve heat dissipation. Such a heat dissipation mode, the external air is only drawn into the network attached storage from the air inlet, the entering dust is less, and since the fan 7 is always blowing air outward for heat dissipation, the internal dust is also easy to be blown to the outside, and the dust is not easy to accumulate around the network attached storage or inside.

[0104] It is also important that the fan 7 in the present application directly interfaces with the main air duct 80 formed by the hard disk insertion space 517, and simultaneously communicates with the air duct of the main control circuit board 82, so that the first hard disk 53 and the main control circuit board 82, which are the components that generate the most heat in the network attached storage, can be directly and effectively cooled, and the cooling effect is better. The main control circuit board 82, as the main control board of the network attached storage, is installed below the mounting frame 51, fully utilizing the bottom space of the network attached storage, and improving the space utilization.

[0105] Specifically, a dust screen is installed on the outer side of the air inlet.

[0114] The hard disk holder 52 of the present application is provided with the pressing unlocking member 522, the rotating unlocking member 523, the unlocking driving member 524, etc. in the front shell 5211. The rotating unlocking member 523 realizes the unlocking of the pressing unlocking member 522 by rotation, and the pressing unlocking member 522 can be pressed after being unlocked for the first time. The end of the pressing unlocking member 522 away from the unlocking driving member 524 is pressed to release the clamping with the unlocking driving member 524, and the unlocking driving member 524 is ejected from the front shell 5211 and drives the lock tongue 525 to retract and unlock for the second time. The locking of the hard disk holder 52 is unlocked by two unlocking operations through the rotation of the rotating unlocking member 523 and the pressing of the pressing unlocking member 522, which avoids the easy unlocking of the hard disk holder 52 by children or other operators, and the data security and equipment safety problems caused by the accidental disassembly of the hard disk, and improves the security of data or equipment.

[0115] Specifically, the holder body 521 further includes a support 5212 connected with the front shell 5211, and the support 5212 is used for mounting a hard disk. The hard disk can be a mechanical hard disk, for example. The network attached storage is provided with a hard disk insertion space 517, and the hard disk insertion space 517 is provided with a lock slot corresponding to the lock tongue 525. The hard disk holder 52 is inserted into the insertion space, and the lock tongue 525 is clamped with the lock slot to realize the locking of the hard disk holder 52. When unlocked, the lock tongue 525 is retracted, and the hard disk holder 52 is unlocked, and the hard disk can be taken out of the hard disk insertion space 517. After the unlocking driving member 524 is ejected from the front shell 5211, it can also be used as a handle for the operator to pull out the hard disk holder 52 from the hard disk insertion space 517.

[0116] Specifically, inside the front shell 5211, the pressing unlocking piece 522 is connected with a first elastic piece 526 for driving the pressing unlocking piece 522 to reset at one end away from the unlocking driving piece 524. The first elastic piece 526 provides the pressing unlocking piece 522 with reset power after being pressed. The first elastic piece 526 can be a spring. The unlocking driving piece 524 is connected with a second elastic piece 527 for driving the unlocking driving piece 524 to pop out of the front shell 5211 at one end away from the pressing unlocking piece 522. The second elastic piece 527 provides the unlocking driving piece 524 with power to pop out of the front shell 5211. The second elastic piece 527 can be a spring or a torsion spring. When relocking, the operator can press the popped-out unlocking driving piece 524 back into the front shell 5211. The pressing unlocking piece 522 and the unlocking driving piece 524 can be rotatably installed in the front shell 5211 through the rotating shaft 529. When the second elastic piece 527 is a torsion spring, the torsion spring can be installed on the rotating shaft 529 for installing the locking driving piece.

[0117] The front shell 5211 is provided with a baffle 52111 corresponding to the rotating unlocking piece 523, and the rotating unlocking piece 523 is provided with an abutting portion 52321. When the rotating unlocking piece 523 is in the locking state, the abutting portion 52321 is opposite to the baffle 52111 to block the abutting portion 52321 when the pressing unlocking piece 522 is pressed. When the rotating unlocking piece 523 is rotated to the unlocking state (i.e., the state shown in FIG. 38), the abutting portion 52321 is misaligned with the baffle 52111. In this scheme, the baffle 52111 and the abutting portion 52321 cooperate to realize the locking and unlocking of the pressing unlocking piece 522 by the rotating unlocking piece 523. Specifically, when the abutting portion 52321 is opposite to the baffle 52111, the rotating unlocking piece 523 is pressed, the abutting portion 52321 will abut on the baffle 52111, and the rotating unlocking piece 523 is in the locked state and cannot be pressed. Rotate the rotating unlocking piece 523 so that the abutting portion 52321 is misaligned with the baffle 52111. At this time, the baffle 52111 cannot block the abutting portion 52321 again, and the rotating unlocking piece 523 can rotate inwardly when pressed, thereby disengaging the locking tongue 525 from the unlocking driving piece 524, and the unlocking driving piece 524 is popped out under the elastic force of the second elastic piece 527, and the locking tongue 525 is retracted and unlocked.

[0118] Specifically, the pressing unlocking piece 522 is provided with a clamping groove 5222 at one end close to the unlocking driving piece 524, and the unlocking driving piece 524 is provided with a clamping protrusion 5241 for clamping in the clamping groove 5222 at one end close to the pressing unlocking piece 522. When the pressing unlocking piece 522 is pressed into the inside of the front shell 5211, the clamping groove 5222 is turned away from the clamping protrusion 5241 at one end, so that the clamping groove 5222 is released from the limiting of the clamping protrusion 5241. After the limiting is released, the unlocking driving piece 524 is popped out of the front shell 5211 under the elastic force of the second elastic piece 527, and at the same time drives the lock tongue 525 to retract and unlock. The side surface of the clamping protrusion 5241 can be provided with a first inclined surface 52411, so as to facilitate the clamping of the clamping protrusion 5241 into the clamping groove 5222. In order to facilitate the clamping of the clamping protrusion 5241 into the clamping groove 5222, the pressing unlocking piece 522 can be pressed first, so that the clamping groove 5222 at one end is turned to increase the activity space of the clamping protrusion 5241. After the unlocking driving piece 524 is pressed back into the front shell 5211, the pressing unlocking piece 522 is released, the clamping groove 5222 presses the clamping protrusion 5241 to realize the locking of the unlocking driving piece 524. Of course, the width of the clamping protrusion 5241 is set to be small enough to be stably clamped in the clamping groove 5222, and the clamping protrusion 5241 can also be directly pressed into the clamping groove 5222.

[0119] Further, in the front shell 5211, the lock tongue 525 is connected with a third elastic piece 528 for driving the lock tongue 525 to extend and lock. Further in combination with the drawings, the lock tongue 525 is provided with a transmission insertion cavity 5251, and the unlocking driving piece 524 is provided with a transmission insertion part 5242 at one end away from the pressing unlocking piece 522, which is inserted into the transmission insertion cavity 5251. When the unlocking driving piece 524 is popped out of the front shell 5211, the transmission insertion part 5242 at one end will push the lock tongue 525 towards the third elastic piece 528 due to the turning, so as to realize the retraction and unlocking of the lock tongue 525, and at the same time the third elastic piece 528 is compressed and stored. After the unlocking driving piece 524 is pressed back into the front shell 5211, the clamping protrusion 5241 is clamped into the clamping groove 5222 to realize the limiting, and after the transmission insertion part 5242 releases the pushing of the lock tongue 525, the lock tongue 525 extends again under the elastic force of the third elastic piece 528 to realize the locking. The lock tongue 525 can be provided with a locking part 5252 extending from the opening 52112 of the front shell 5211, and the bottom of the locking part 5252 can be provided with a second inclined surface 52521, so as to facilitate the locking part 5252 to enter and exit the locking slot in the hard disk insertion space 517.

[0120] Specifically, as shown in FIGS. 1-3, the pressing unlocking piece 522 is provided with a first through hole 5221, and the rotating unlocking piece 523 is rotatably installed in the first through hole 5221. The rotating unlocking piece 523 includes a rotating sub-piece 5231, and the peripheral surface of the rotating sub-piece 5231 is provided with a bearing protrusion 52311; the inner wall of the first through hole 5221 is provided with a resisting protrusion 52211, and the bearing protrusion 52311 bears on the resisting protrusion 52211. The resisting protrusion 52211 cooperates with the bearing protrusion 52311 to facilitate the installation of the rotating sub-piece 5231. The top of the rotating sub-piece 5231 can be provided with a rotating groove 52313, and an operator can rotate the rotating sub-piece 5231 through the rotating groove 52313 to realize the locking and unlocking of the rotating unlocking piece 523.

[0121] Further, the peripheral surface of the rotating sub-piece 5231 is provided with a resisting protrusion 52312, and a gap region 52212 is formed between the two ends of the resisting protrusion 52211, and the resisting protrusion 52312 is located in the gap region 52212. When the rotating unlocking piece 523 is rotated to the locking state, the resisting protrusion 52312 resists one end of the resisting protrusion 52211. When the rotating unlocking piece 523 is rotated to the unlocking state, the resisting protrusion 52312 resists the other end of the resisting protrusion 52211. By resisting the two ends of the resisting protrusion 52211 through the resisting protrusion 52312, the rotation of the rotating unlocking piece 523 can be limited within the rotation range of the locking and unlocking, so as to avoid excessive rotation during locking or unlocking, and facilitate the locking and unlocking.

[0122] Further, the rotating unlocking piece 523 further includes a mounting sub-piece 5232, and an abutting portion 52321 is arranged at the bottom of the mounting sub-piece 5232; the mounting sub-piece 5232 is provided with a mounting insertion cavity 52322, and the end of the rotating sub-piece 5231 away from the resisting protrusion 52211 is inserted and mounted in the mounting insertion cavity 52322. The mounting insertion cavity 52322 can facilitate the assembly of the mounting sub-piece 5232 and the rotating sub-piece 5231, and can improve the connection stability after the assembly. The mounting sub-piece 5232 and the rotating sub-piece 5231 can be connected through screws.

[0123] The circumferential wall of the mounting sub-piece 5232 is provided with two oppositely arranged arc-shaped protrusions 52323, and the inner wall of the first through hole 5221 is provided with four evenly spaced arc-shaped grooves 52213. The central angle of the gap area 52212 is °. When the rotation unlocking piece 523 is rotated to the locking state, the two arc-shaped protrusions 52323 are rotated into two opposite arc-shaped grooves 52213; when the rotation unlocking piece 523 is rotated to the unlocking state, the two arc-shaped protrusions 52323 are rotated into the other two opposite arc-shaped grooves 52213. The cooperation between the two arc-shaped protrusions 52323 and the four evenly spaced arc-shaped grooves 52213 can ensure that the rotation unlocking piece 523 is stably rotated, and the feel when the arc-shaped protrusion 52323 is embedded into the arc-shaped groove 52213 can prompt the operator that the locking or unlocking of the rotation unlocking piece 523 has reached the position. At the same time, the cooperation between the arc-shaped protrusion 52323 and the arc-shaped groove 52213 can also position the rotation unlocking piece 523.

[0124] Specifically, the arc-shaped groove 52213 extends to the inner side edge of the first through hole 5221, and when the mounting sub-piece 5232 is assembled into the first through hole 5221, the arc-shaped groove 52213 extending to the inner side edge of the first through hole 5221 can guide the arc-shaped protrusion 52323.
