The unlocking button 4 is also arranged on the bracket front panel 1 and can be pressed, in the pressing stroke, the tail end of the unlocking button 4 can form point-to-surface butt joint with the surface of the locking piece 3, so that a rotating moment is formed on the locking piece 3, the locking piece 3 is driven to rotate by a preset angle, and when the locking piece 3 rotates to the position, the locking piece 3 is separated from the bracket handle 2 in a clamping state; at this time, the bracket handle 2 is unlocked and can be smoothly unfolded out of the bracket front panel 1, and a worker can conveniently grip and apply force to the bracket front panel.

So, the hard disk support module lock solid release mechanism that this embodiment provided makes formation rotatory unblock between fastener 3 and support handle 2 through the point and the face contact between with fastener 3 in the stroke of pushing down of unlock button 4, compare in prior art, reduced the area of contact between unlock button 4 and the fastener 3, and the rotatory stroke of rotatory unblock mode is shorter, unlock button 4 is also shorter with the contact time of fastener 3, under long-term the use, be difficult for producing between the two to be stained with and glue, therefore structural reliability and life are higher.

As shown in fig. 2, fig. 2 is a specific structural diagram of the bracket handle 2 in an unlocked and unfolded state.

In a preferred embodiment with respect to the stand handle 2, the stand handle 2 can be stowed and deployed by a rotational movement. Specifically, the head end of the bracket handle 2 can be connected with the bracket front panel 1 through the pivot 5, so that the bracket handle 2 and the bracket front panel 1 can be rotatably connected, and the bracket handle 2 can be ensured to perform overturning motion on the bracket front panel 1. Of course, the turning motion of the support handle 2 is toward the opening of the hard disk support, and when the support handle 2 is not turned, the whole support handle 2 can be accommodated in the opening of the hard disk support, and the tail end of the support handle is clamped and fixed with the locking piece 3. When the bracket handle 2 is turned outwards for a certain angle, the bracket handle 2 is unfolded to the outside of the opening of the hard disk bracket, and a worker can conveniently grasp the bracket.

Further, in the present embodiment, a torsion spring is sleeved on the periphery of the pivot 5, specifically, the torsion spring has an elastic force along the circumferential direction, and when the support handle 2 is turned over to the outside of the opening of the hard disk support, the torsion spring is in a natural state, i.e., is not compressed. And when the support handle 2 was accomodate in the opening of hard disk support, the torsional spring was in and is compressed state, accumulated and had certain elastic potential energy, nevertheless because locking part 3 was to the terminal joint of support handle 2, the unable release energy of torsional spring keeps compressed state, only when locking part 3 was to support handle 2 unblock, the torsional spring just can begin to reset to pop out support handle 2 outside the hard disk support opening through elastic force rapidly.

In another preferred embodiment with respect to the stand handle 2, the stand handle 2 may be stowed and deployed by a linear motion. Specifically, the holder handle 2 may have a rectangular shape, and may be installed in an opening of the hard disk holder while being capable of reciprocating back and forth in the opening. At this time, the locking member 3 is engaged with the sidewall of the holder handle 2 to lock the holder handle 2 in the opening. After the locking piece 3 unlocks the bracket handle 2, the bracket handle 2 can be drawn out from the opening to the outside.

For the convenience of discussion, the following description of the present embodiment will be made based on a structure in which the rack handle 2 is folded and unfolded by a turning motion.

As shown in fig. 3, 4 and 5, fig. 3 is a partial structural view of the rack handle 2 in a locked and stored state, fig. 4 is a partial structural view of the rack handle 2 being unlocked, and fig. 5 is another view of fig. 4.

The front end of hard disk support not only is provided with support front panel 1, and for conveniently accomodating support handle 2, roof 6 before the support has been set up at support front panel 1's top to this embodiment, has set up support front bottom plate 7 in support front panel 1's bottom simultaneously to, roof 6 and support front bottom plate 7 all extend to the place ahead (towards the opening outside) before the support, form the slot-shaped structure jointly with support front panel 1. To ensure that the frame handle 2 can perform the tilting motion smoothly, in the embodiment, the pivot 5 of the frame handle 2 can be vertically connected between the frame front top plate 6 and the frame front bottom plate 7, and is generally connected at the side positions of the frame front top plate 6 and the frame front bottom plate 7. With the arrangement, the bracket handle 2 can perform overturning opening and closing movement on the bracket front panel 1 through the rotation of the pivot 5.

The position department of the end (pivot 5 is installed to the head end) that lies in support handle 2 has seted up mounting groove 8 on support front panel 1, and unlock button 4 sets up promptly in this mounting groove 8 simultaneously to can reciprocate to slide in mounting groove 8, in order to make things convenient for the staff to press. Because the unlocking button 4 needs to form a point-surface abutting driving effect with the locking piece 3 in the pressing sliding stroke of the unlocking button 4, for this reason, in this embodiment, the locking piece 3 may be specifically disposed between the bracket front top plate 6 and the bracket front bottom plate 7, and at the same time, is located on the bracket front panel 1 at a position corresponding to the mounting groove 8, so as to facilitate the abutting of the tail end of the unlocking button 4. In particular, the locking member 3 is a rotating member as well as the pivot 5, so that the locking member 3 can also be vertically connected between the front top bracket plate 6 and the front bottom bracket plate 7.

In a preferred embodiment of the unlock button 4, the main body of the unlock button 4 is installed in the installation groove 8, and a plurality of support legs 401 are connected to the bottom of the unlock button 4, and correspondingly, a plurality of through holes are opened on the groove bottom plate of the installation groove 8, and the support legs 401 are respectively inserted into the through holes and can slide therein. Thus, when the worker presses the unlocking button 4 in the mounting groove 8, the main body of the unlocking button 4 slides in the mounting groove 8, and the respective support legs 401 slide in cooperation with the respective through holes and are gradually pressed down to extend toward the surface of the bracket front panel 1. The length of the end of each leg 401 is determined according to the maximum sliding stroke of the unlocking button 4 and the distance from the surface of the locking member 3, so that when the unlocking button 4 is pressed to the maximum sliding stroke, the end of each leg 401 can stably form point-surface abutment with the surface of the fastening member, and the fastening member can be driven to rotate to be separated from the clamping of the end of the bracket handle 2.

Further, rotating and loosening the back at the staff when unblock button 4 drive fastener, the fastener will be automatic re-setting under elastomeric element's effect, and the fastener will drive unblock button 4 reverse slip at reverse rotation's in-process this moment, for preventing that unblock button 4 directly deviates from in mounting groove 8, back-off 402 has been add to this embodiment on the end of each stabilizer blade 401. Specifically, this back-off 402 can set up on the outer fringe of stabilizer blade 401 end along the hoop, and its external diameter is greater than the through-hole diameter of seting up on the groove bottom plate of mounting groove 8, and like this, when release button 4 reverse slip, back-off 402 can the overhead kick on the pore wall bottom surface of through-hole, prevents release button 4 to continue to slide, prevents that release button 4 from deviating from in mounting groove 8.

In a preferred embodiment of the locking member 3, the locking member 3 mainly includes a rotation shaft 301, an abutting plate 302 and a clamping plate 303. Wherein, the two ends of the rotating shaft 301 can be vertically connected to the bracket front top plate 6 and the bracket front bottom plate 7 respectively and keep rotating connection. The abutting plate 302 is fixedly connected to a side surface of the rotating shaft 301 and can rotate synchronously with the rotation of the rotating shaft 301. The clamping plate 303 is also fixedly connected to a side surface of the rotating shaft 301, and can also rotate synchronously with the rotation of the rotating shaft 301, but the arrangement directions of the clamping plate 303 and the abutting plate 302 on the rotating shaft 301 are different, and a certain included angle is formed between the clamping plate 303 and the abutting plate 302. Here, the clamping plate 303 and the abutting plate 302 may be perpendicular to each other. Of course, the included angle between the circle centers of the clamping plate 303 and the abutting plate 302 can be generally any angle between 60 degrees and 120 degrees.

As described above, the specific position of the rotation shaft 301 may be near the mounting groove 8, and in a natural state (an unstressed rotated state), the surface of the abutting plate 302 may be directly opposite to the bottom surface of the mounting groove 8 and may be closely attached to the bottom surface of the mounting groove 8, so that the end of the leg 401 of the unlocking button 4 can smoothly form a point-surface abutment with the surface of the abutting plate 302 during the pressing stroke. Meanwhile, the surface of the clamping plate 303 can be directly opposite to the end face of the tail end of the bracket handle 2 in a natural state, so that clamping is conveniently formed between the clamping plate and the bracket handle 2.

Further, to ensure that the abutting plate 302 can form a point-surface abutment with each leg 401 at the same time, the present embodiment extends a plurality of protruding plates 304 on the end of the abutting plate 302. Specifically, each protruding plate 304 may be connected to the end surface of the abutting plate 302 in a branched manner, and the distribution position of each protruding plate 304 on the abutting plate 302 is the same as the distribution position of each supporting leg 401 on the unlocking button 4, so as to set the end of each supporting leg 401 to correspond to each protruding plate 304, so as to abut against the surface of the abutting plate 302 at the same time, and apply a rotation moment to the rotating shaft 301 at the same time.

As shown in fig. 6, fig. 6 is a partial sectional view of the mounting groove 8 and the locking member 3 shown in fig. 1.

Furthermore, in order to ensure that the locking member 3 can smoothly rotate in the reverse direction and reset after the pressed rotation is finished, the present embodiment has a barrel-shaped groove 305 on the back surface of each protruding plate 304, and meanwhile, the spring 9 is installed in each barrel-shaped groove 305. One end of the spring 9 may be connected to the bottom of the cylindrical groove 305, and the other end of the spring 9 is connected to the surface of the bracket front panel 1. So configured, when the abutting plate 302 in the locking member 3 is pressed by the unlocking button 4, the rotating shaft 301 is forced to rotate, and simultaneously the abutting plate 302 compresses each spring 9, so that each spring 9 accumulates certain elastic potential energy. When the worker loosens his hands, the pressure of the unlocking button 4 is released, each spring 9 starts to release elastic potential energy, the rotating shaft 301 is driven to rotate reversely until the unlocking button is reset, and meanwhile, the abutting plate 302 synchronously rotates reversely to drive the unlocking button 4 to slide reversely in the mounting groove 8 until the unlocking button is reset. Of course, during the extension and retraction of the spring 9, the abutting plate 302 rotates, so that not only the axial pressure is generated on the spring 9, but also the spring 9 is twisted and deformed to some extent.

In a preferred embodiment of the clamping structure formed between the locking member 3 and the holder handle 2, the wedge-shaped groove 201 is formed on the end surface of the holder handle 2, and the wedge-shaped block 306 is disposed on the end surface of the clamping plate 303, and the wedge-shaped block 306 can cooperate with the wedge-shaped groove 201 to form a clamping connection. In a natural state, the surface of the clamping plate 303 faces the end face of the bracket handle 2, and the wedge block 306 is buckled in the wedge groove 201, so that the wedge block and the wedge groove are interlocked. When the unlocking button 4 is pressed, the locking member 3 is pressed to rotate (anticlockwise rotation as shown in the figure), so that the wedge block 306 is driven to synchronously rotate, the wedge block 306 is separated from the wedge groove 201, a space is avoided for the overturning motion of the bracket handle 2, and the motion interference caused by the outward overturning and unfolding of the bracket handle 2 is avoided.

Generally, the locking member 3 can be rotated by 15-25 ° under pressure to ensure that the wedge block 306 is completely released from the wedge groove 201. Of course, the specific rotation angle of the locking member 3 is determined by the depth of the wedge block 306 and the wedge groove 201, and the size of the structure. Meanwhile, the specific structural design of this embodiment will leave a certain margin for the rotational movement of the locking member 3, that is, after the unlocking button 4 is pressed to the maximum stroke, the rotational angle of the locking member 3 already exceeds the rotational angle required for releasing the clamping. In addition, in this embodiment, a wall surface of the mounting groove 8 facing the clamping plate 303 is used as a limiting surface 801 for limiting the rotation of the clamping plate 303, that is, when the clamping plate 303 rotates to abut against the wall surface of the mounting groove 8, the clamping plate 303 cannot rotate continuously, and the locking member 3 reaches the maximum rotation angle. Generally, the maximum rotation angle of the locking member 3 can be controlled to about 30 ° by the abutting limit action of the limit surface 801 on the mounting groove 8. Obviously, the larger the groove width of the mounting groove 8 is, the smaller the distance between the limiting surface 801 and the clamping plate 303 is, the smaller the maximum rotation angle that can be limited is, and vice versa.

In addition, considering that after the fastener unlocks the bracket handle 2, in the process of turning back and accommodating the bracket handle 2 again, the end face of the tail end of the bracket handle 2 abuts against the surface of the wedge block 306 on the fastener, the fastener is forced to rotate under the action of the unlocking button 4 by means of abutting pressure, the bracket handle 2 is avoided, and after the bracket handle 2 is completely accommodated in the bracket handle, the fastener rotates and resets under the action of the elastic force of the spring 9 and forms clamping locking with the bracket handle 2 again. In order to reduce the abrasion and friction of the bracket handle 2 on the surface of the wedge block 306 during the storage process, in the embodiment, the end surface of the end of the bracket handle 2 may be specifically a slope, and the slope angle of the slope may be equivalent to the slope angle of the wedge block 306.
