Description

Technical Field

[0001] The utility model relates to the technical field of computer storage, in particular to a hard disk box and a chassis. Background Art

[0002] With the rapid development of networks and multimedia, hard disks, as large-capacity storage devices, are widely used. Ordinary hard disks are generally installed in a chassis through a hard disk box. For a hard disk box, how to optimize the disassembly and assembly convenience has become a technical problem to be solved urgently. The prior art provides a quick-release hard disk box, which includes a hard disk tray bottom shell, a handle and an elastic buckle arranged outside the hard disk tray bottom shell. The elastic buckle is inclined outwards under the action of a buckle spring plate in a natural state. When installed in the chassis, under the downward sliding pressure, the elastic buckle is close to the hard disk tray bottom shell. After the hard disk tray bottom shell is in place, a positioning boss on the hard disk tray bottom shell cooperates with a positioning boss hole on the chassis under the action of the buckle spring plate, and then the hard disk tray bottom shell can be clamped on the chassis. The elastic buckle can be unlocked by operating the handle, and further operating the handle can realize the plugging and unplugging of the hard disk module in the chassis.

[0003] However, the premise of unlocking the elastic buckle by operating the handle is that the positioning boss needs to keep a certain distance from the hard disk tray bottom shell in a natural state. To ensure the distance between the positioning boss and the hard disk tray bottom shell, generally, the distance between the riveting hole position and the positioning boss is lengthened, which will lead to an over-large volume of the elastic buckle, reduce the space utilization rate of the quick-release hard disk box, and increase the manufacturing cost of the quick-release hard disk box. Summary of the Utility Model

[0004] The first aspect of the utility model provides a hard disk box to solve the defect that the volume of the elastic buckle in the prior art is over-large. Since the distance between the first clamping member and the tray main body is determined by the second elastic member, there is no need to lengthen the third elastic member or change the connection position between the second elastic member and the third elastic member to ensure the distance between the first clamping portion and the tray main body, which can effectively reduce the overall volume of the elastic component, improve the space utilization rate of the hard disk box, and reduce the manufacturing cost of the hard disk box.

[0005] The second aspect of the utility model provides a chassis.

[0006] The hard disk box provided by the utility model includes:

[0007] A tray main body;

[0008] An elastic member is provided at at least one end of the bracket main body. The elastic member includes a first elastic member, a second elastic member, and a third elastic member. The first elastic member and the third elastic member are oppositely arranged. One end of the second elastic member is connected to the first elastic member, and the other end is connected to the third elastic member. The first elastic member is connected to the bracket main body. A first clamping portion is provided on a surface of the third elastic member away from the first elastic member. The first clamping portion is used to cooperate with a second clamping portion of the chassis main body;

[0009] A lifting member is connected to the third elastic member. The lifting member is adapted to drive the third elastic member to swing towards the first elastic member, so that the first clamping portion is separated from the second clamping portion.

[0010] According to the hard disk box provided by the present invention, the elastic member further includes a fourth elastic member. The fourth elastic member is provided at an end of the third elastic member away from the second elastic member. The fourth elastic member is provided with a connecting groove, and the connecting groove is used for flexible connection with the lifting member.

[0011] According to the hard disk box provided by the present invention, the fourth elastic member and the third elastic member are arranged at an angle, and the opening of the angle faces the second elastic member.

[0012] According to the hard disk box provided by the present invention, at least one end of the lifting member is provided with a protrusion, and the protrusion is adapted to abut against the fourth elastic member after passing through the connecting groove.

[0013] According to the hard disk box provided by the present invention, the lifting member further includes a through groove. The through groove is provided on a side of the protrusion away from the fourth elastic member, and the through groove is used to assist the protrusion to pass through the connecting groove.

[0014] According to the hard disk box provided by the present invention, the elastic member further includes a fifth elastic member. The fifth elastic member is provided at an end of the first elastic member away from the second elastic member and is perpendicular to the first elastic member. The first elastic member is adapted to be fixedly connected to the bracket main body through the fifth elastic member.

[0015] According to the hard disk box provided by the present invention, in the case where the elastic member is only provided at one end of the bracket main body, the hard disk box further includes a fixing member. The fixing member and the elastic member are oppositely arranged at both ends of the bracket main body. One end of the lifting member is connected to the elastic member, and the other end is connected to the fixing member.

[0016] According to the hard disk box provided by the present invention, one end of the lifting member is flexibly connected to the elastic member, and the other end is flexibly connected to the fixing member.

[0017] According to the hard disk box provided by the present utility model, the bracket body is provided with an installation groove and a limiting member. The limiting member is located above the installation groove. The elastic member is arranged in the installation groove. The limiting member is used to limit the displacement of the fourth elastic member in the vertical direction.

[0018] The chassis provided by the present utility model includes the hard disk box described in any one of the preceding claims.

[0019] For the hard disk box provided by the present utility model, after installing the hard disk into the hard disk box, the hard disk box with the hard disk can be transferred above the assembly groove of the chassis main body through the lifting member. Due to the self-weight of the hard disk box and the hard disk, the third elastic member will be in a state close to the first elastic member at this time, and the first clamping portion can be understood to be in a contracted state. When the hard disk box falls to a suitable position in the chassis assembly groove, the user releases the lifting member, and the third elastic member will return to its original initial state. During this process, the third elastic member will move in a direction away from the first elastic member, and the first clamping portion can be understood to be in an extended state, and then cooperate with the second clamping portion in the assembly groove to realize the clamping cooperation between the hard disk box and the chassis main body.

[0020] When it is necessary to take out the hard disk box, the user pulls the lifting member. The lifting member drives the third elastic member to swing towards the first elastic member. The first clamping portion retracts and separates from the second clamping portion, so that the clamping between the first clamping portion and the second clamping portion fails. Continuing to pull the pulling member can directly lift the hard disk box out of the chassis main body. In this way, the quick insertion and extraction of the hard disk box can be realized, the disassembly and assembly convenience of the hard disk box can be improved, and this structure is convenient to operate and can improve the production operation efficiency.

[0021] Compared with the prior art, for the hard disk box provided by the embodiment of the present utility model, by arranging the second elastic member between the first elastic member and the third elastic member, in this way, the third elastic member and the first elastic member can be naturally separated by the second elastic member. The third elastic member is not directly connected to the bracket body and can maintain a distance from the bracket body in the natural state. This distance can be used as the swinging space of the third elastic member. In this way, it is not necessary to bend the third elastic member away from the bracket body to ensure the distance between the first clamping portion and the bracket body, and there is no problem of the bending angle.

[0022] In addition, the distance between the first clamping portion and the bracket body is determined by the second elastic member, and is not affected by the connection between the third elastic member and the second elastic member, that is, not affected by the length of the third elastic member, and there is no influence of the deflection angle. In this way, it is not necessary to lengthen the third elastic member or change the connection position between the second elastic member and the third elastic member to ensure the distance between the first clamping portion and the bracket body. In this way, the overall volume of the elastic component can be effectively reduced, the space utilization rate of the hard disk box can be improved, and the manufacturing cost of the hard disk box can be reduced. In addition, since the third elastic member maintains a distance from the bracket body due to the second elastic member in the natural state, when the hard disk box is installed in the chassis, only the clamping stress transfer between the first clamping portion and the second clamping portion will occur, and the chassis will not compress the third elastic member to move towards the first elastic member, that is, the third elastic member will not be squeezed by the chassis, and naturally there will be no problem of plastic deformation leading to structural failure. Based on this, the service life of the elastic component can be greatly extended. Description of the Drawings

[0042] With the rapid development of the network and multimedia, people increasingly often encounter large-capacity data exchanges measured in GB. Facing such large chunks of data, hard disks are undoubtedly the best carriers. However, ordinary hard disks are installed in the chassis and have an operating system installed, so they are not easy to move. The role of a hard disk enclosure is to physically protect a hard disk and, at the same time, use a connection method that is convenient for movement to achieve the function of a portable hard disk. For a hard disk enclosure, how to optimize the disassembly and assembly convenience has become a technical problem to be solved urgently.

[0043] Figure 1 is a schematic structural diagram of a quick-disassembly hard disk enclosure in the prior art; Figure 2 is Figure 1 an enlarged schematic diagram of the local structure at in.

[0044] Refer to Figure 1 and Figure 2, the prior art provides a quick-release hard disk enclosure. This quick-release hard disk enclosure includes a hard disk carrier bottom case 1, a handle 4, elastic buckles 5, and bottom case sliders 6 arranged around the hard disk carrier bottom case 1. The hard disk 3 is arranged inside the hard disk carrier bottom case 1. The hard disk carrier bottom case 1 is composed of a first side, a second side, a third side, and a bottom surface. The two elastic buckles 5 are respectively arranged on the edges formed by the third side and the first side and the second side. The elastic buckle 5 includes a buckle spring plate 54. The elastic buckle 5 inclines upward and outward at the buckle spring plate 54. The handle 4 crosses the third side to connect the two elastic buckles 5. A positioning boss 53 is arranged outside the elastic buckle 5, and the positioning boss 53 cooperates with the positioning boss hole on the chassis. The elastic buckle 5 inclines outward under the action of the buckle spring plate 54 in the natural state. When it is installed in the chassis, under the downward sliding pressure, the elastic buckle 5 is close to the hard disk carrier bottom case 1. After the hard disk carrier bottom case 1 is in place, the positioning boss 53 cooperates with the positioning boss hole under the action of the buckle spring plate 54, and the hard disk carrier bottom case 1 can be clamped on the chassis, and then the hard disk 3 can be firmly fixed on the chassis. By operating the handle 4 to unlock the elastic buckle 5, further operating the handle 4 can realize the plugging and unplugging of the hard disk module from the chassis.

[0045] However, the premise for the handle 4 to operate and unlock the elastic buckle 5 is to ensure that the buckle spring plate 54 has a suitable deformation space, that is, the positioning boss 53 needs to maintain a certain distance from the hard disk carrier bottom case 1 in the natural state. In other words, the distance that the buckle spring plate 54 inclines outward needs to be large enough so as to ensure that when the handle 4 pulls the positioning boss 53 to retract, it can completely leave the positioning boss hole. There are two factors that can affect the distance between the positioning boss 53 and the hard disk carrier bottom case 1. One is the deflection angle of the buckle spring plate 54. The larger the deflection angle, the larger the distance between the positioning boss 53 and the hard disk carrier bottom case 1. The other is the distance between the riveting hole position 56 and the positioning boss 53. The larger the distance at this place, the larger the distance between the positioning boss 53 and the hard disk carrier bottom case 1.

[0046] However, the larger the deflection angle, when the handle 4 unlocks the elastic buckle 5, it will cause the deformation amplitude of the buckle spring plate 54 to be too large, which will cause the buckle spring plate 54 to be easily broken or the structure to fail. Therefore, to ensure the distance between the positioning boss 53 and the hard disk carrier bottom case 1, generally, the distance between the riveting hole position 56 and the positioning boss 53 is lengthened, that is, the buckle spring plate 54 is lengthened. However, this will cause the overall volume of the elastic buckle 5 to be too large, reducing the space utilization rate of the quick-release hard disk enclosure and at the same time increasing the manufacturing cost of the quick-release hard disk enclosure. In addition, after the buckle spring plate 54 is installed, it will be squeezed by the chassis for a long time, that is, the positioning boss 53 will be stressed for a long time. As the use time increases, the original deflection angle of the buckle spring plate 54 will produce plastic deformation, and then the structure will fail, affecting the use of the elastic buckle 5.

[0047] In addition, the handle 4 and the elastic buckle 5 are connected by a rotating shaft. The conversion efficiency of the rotating shaft for the pulling force is relatively low, resulting in a relatively small horizontal force on the elastic buckle 5, which affects the displacement change of the buckle spring plate 54 during operation. In other words, in the case of the same displacement change, more pulling force needs to be provided by the handle 4.

[0048] Figure 3 is a schematic diagram of the overall structure of the hard disk box provided by an embodiment of the present invention; Figure 4 is a schematic diagram of the structure of the elastic member provided by an embodiment of the present invention; Figure 5 is a schematic diagram of the structure of the bracket main body provided by an embodiment of the present invention.

[0049] Refer to Figure 3 With reference to FIGS. 4, in a first aspect of the embodiments of the present invention, a hard disk box 100 is provided, aiming to solve at least one of the above-mentioned technical problems in the prior art. The hard disk box 100 provided by the embodiments of the present invention includes a bracket main body 400, an elastic member 500, and a lifting member 600.

[0050] Refer to Figure 5 , the bracket main body 400 is approximately a rectangular outer shell. The bracket main body 400 specifically includes a first side plate 430, a second side plate 440, and a third side plate 450. The first side plate 430 and the third side plate 450 are oppositely arranged at both ends of the second side plate 440 and are respectively perpendicular to the second side plate 440 at the same time, so as to be adapted to the cuboid structure of the hard disk 800. Installation holes, limiting grooves, etc. for fixing the hard disk 800 are respectively formed on the first side plate 430, the second side plate 440, and the third side plate 450. Specifically, the first side plate 430, the second side plate 440, and the third side plate 450 can be designed adaptively with reference to the prior art, which will not be elaborated herein.

[0051] The elastic member 500 is provided at at least one end of the second side plate 440, that is, at at least one end of the bracket main body 400. In other words, the elastic member 500 can be provided only at one end of the second side plate 440, or elastic members 500 can be respectively provided at both ends of the second side plate 440. For the convenience of description, in this article, an example in which the elastic member 500 is provided only at one end of the second side plate 440 is taken. For example, the elastic member 500 is provided at the end of the second side plate 440 close to the first side plate 430 for illustration.

[0052] The elastic component 500 includes a first elastic member 510, a second elastic member 520, and a third elastic member 530. The first elastic member 510 and the third elastic member 530 are oppositely arranged at both ends of the second elastic member 520 and are respectively perpendicular to the second elastic member 520. The first elastic member 510 is connected to the bracket main body 400. In an alternative embodiment of the present utility model, the first elastic member 510 can be fixedly connected to the second side plate 440 or the first side plate 430, and can be adaptively selected according to the actual situation.

[0053] The planes where the first elastic member 510 and the third elastic member 530 are located are both parallel to the plane where the first side plate 430 is located, and the plane where the second elastic member 520 is located is parallel to the plane where the second side plate 440 is located. Among them, the first elastic member 510, the second elastic member 520, and the third elastic member 530 can all be made of plates, which have low processing difficulty and are easy to shape. Of course, in an alternative embodiment of the present utility model, the first elastic member 510, the second elastic member 520, and the third elastic member 530 can also be made of rods or pipe fittings, etc. Specifically, it can be adaptively selected according to the actual situation.

[0054] A first clamping portion 540 is provided on the side of the third elastic member 530 away from the first elastic member 510. The first clamping portion 540 is used to cooperate with the second clamping portion 300 on the chassis main body 200. The first clamping portion 540 can be either a buckle or a clamping groove, and the second clamping portion 300 can be the other one of the buckle or the clamping groove. Specifically, it can be adaptively selected according to the actual situation.

[0055] The lifting component 600 is connected to the third elastic member 530. During use, the user can drive the third elastic member 530 to swing towards the first elastic member 510 by pulling the lifting component 600, and the swing axis is the connection part of the third elastic member 530 and the second elastic member 520. In this way, the first clamping portion 540 can be separated from the second clamping portion 300, making the clamping cooperation between the two ineffective.

[0056] Refer to Figure 3 and Figure 4It can be understood that for the hard disk case 100 provided by the embodiment of the present utility model, after the hard disk 800 is installed in the hard disk case 100, the hard disk case 100 with the hard disk 800 can be transferred above the assembly slot of the chassis main body 200 through the lifting member 600. Due to the self-weight of the hard disk case 100 and the hard disk 800, the third elastic member 530 will be in a state close to the first elastic member 510 at this time, and the first engaging portion 540 can be understood to be in a contracted state. When the hard disk case 100 falls to a suitable position in the chassis assembly slot, the user releases the lifting member 600, and the third elastic member 530 will return to its original initial state. During this process, the third elastic member 530 will move in a direction away from the first elastic member 510, and the first engaging portion 540 can be understood to be in an extended state, and then cooperate with the second engaging portion 300 in the assembly slot to achieve the snap-fit between the hard disk case 100 and the chassis main body 200.

[0057] When the hard disk case 100 needs to be taken out, the user pulls the lifting member 600, and the lifting member 600 drives the third elastic member 530 to swing towards the first elastic member 510. The first engaging portion 540 retracts and separates from the second engaging portion 300, so that the snap-fit between the first engaging portion 540 and the second engaging portion 300 fails. By continuing to pull the pulling member, the hard disk case 100 can be directly lifted out of the chassis main body 200. In this way, the quick plugging and unplugging of the hard disk case 100 can be realized, the disassembly and assembly convenience of the hard disk case 100 can be improved, and this structure is convenient to operate and can improve the production operation efficiency.

[0058] Compared with the prior art, for the hard disk case 100 provided by the embodiment of the present utility model, by arranging the second elastic member 520 between the first elastic member 510 and the third elastic member 530, in this way, the third elastic member 530 and the first elastic member 510 can be naturally separated by the second elastic member 520, and the third elastic member 530 is not directly connected to the bracket main body 400, and can maintain a distance from the bracket main body 400 in the natural state. This distance can be used as the swinging space of the third elastic member 530. In this way, it is not necessary to bend the third elastic member 530 away from the bracket main body 400 to ensure the distance between the first engaging portion 540 and the bracket main body 400, and there is no problem of bending angle.

[0059] In addition, the distance between the first clamping portion 540 and the bracket main body 400 is determined by the second elastic member 520, and is not affected by the connection portion of the third elastic member 530 and the second elastic member 520, that is, not affected by the length of the third elastic member 530, and there is no influence of the deflection angle at the same time. In this way, it is not necessary to lengthen the third elastic member 530 or change the connection position of the second elastic member 520 and the third elastic member 530 to ensure the distance between the first clamping portion 540 and the bracket main body 400. In this way, the overall volume of the elastic component 500 can be effectively reduced, the space utilization rate of the hard disk box 100 can be improved, and the manufacturing cost of the hard disk box 100 can be reduced; in addition, in the natural state, the third elastic member 530 maintains a distance from the bracket main body 400 because of the second elastic member 520. Therefore, after the hard disk box 100 is installed in the chassis, only the clamping stress transmission between the first clamping portion 540 and the second clamping portion 300 will exist, and the chassis will not compress the third elastic member 530 to move towards the first elastic member 510, that is, the third elastic member 530 will not be squeezed by the chassis, and naturally there will be no problem of plastic deformation leading to structural failure. Based on this, the service life of the elastic component 500 can be greatly extended.

[0060] Continue to refer to Figure 4 , in an alternative embodiment of the present invention, the elastic component 500 further includes a fourth elastic member 550. The fourth elastic member 550 is disposed at the end of the third elastic member 530 away from the second elastic member 520. A connection groove 560 is provided on the fourth elastic member 550. The connection groove 560 is used for flexible connection with the lifting component 600. In use, the lifting component 600 is adapted to pass through the connection groove 560 and abut against the fourth elastic member 550, thereby realizing the transmission of stress. It can be understood that, compared with the rigid connection in the prior art, the flexible connection itself has a certain movement space. On the one hand, it can facilitate the assembly between the second elastic member 520 and the lifting component 600. On the other hand, the lifting component 600 generates an obliquely upward pulling force on the fourth elastic member 550, and the flexible connection can better convert the pulling force into the horizontal force required for the fourth elastic member 550 and the third elastic member 530 to move towards the first elastic member 510. In this way, it is beneficial to reduce the pulling force required to lift the hard disk box 100, and can play a role in facilitating operation.

[0061] Continue to refer to Figure 4 , in an alternative embodiment of the present invention, the fourth elastic member 550 and the third elastic member 530 are arranged at an angle, and the opening of the angle faces the second elastic member 520. It should be noted that in this case, the height of the third elastic member 530 needs to exceed the first elastic member 510 to avoid position interference between the fourth elastic member 550 and the first elastic member 510; the angle can be adaptively set according to the actual situation as long as it conforms to the actual mechanical principle.

[0062] It can be understood that when the lifting member 600 generates an obliquely upward pulling force on the fourth elastic member, this pulling force will be decomposed into a force in the horizontal direction and a force in the vertical direction. The force in the horizontal direction will be used to drive the fourth elastic member 550 and the third elastic member 530 to move towards the first elastic member 510. The force in the vertical direction has no effect on the lateral movement of the fourth elastic member 550 and the third elastic member 530. As the fourth elastic member 550 and the third elastic member 530 continuously move towards the first elastic member 510, the angle between the obliquely upward pulling force generated by the lifting member 600 on the fourth elastic member and the horizontal plane will become larger and larger. In this way, the effect of converting the pulling force into a horizontal force will become worse and worse (the horizontal force is equal to the pulling force multiplied by the cosine value of the included angle). However, by arranging the fourth elastic member 550 and the third elastic member 530 at an included angle, due to the inclined surface setting of the fourth elastic member 550, in this way, the effect of converting the pulling force into a horizontal force can be improved. This part of the effect can be obtained through actual experiments and force analysis.

[0063] Figure 6 It is a schematic structural diagram of the lifting member provided by the embodiment of the present invention.

[0064] Refer to Figure 3 and Figure 6 In an alternative embodiment of the present invention, the end of the lifting member 600 adjacent to the fourth elastic member 550 can be provided as a plate-like member, or the lifting member 600 can be directly provided as a plate-like member. A protrusion 610 can be provided at the end of the lifting member 600. The protrusion 610 is adapted to pass through the connecting groove 560 and then abut against the fourth elastic member 550. It can be understood that the protrusion 610 can act as a hook, so as to abut against the lower bottom surface of the side wall of the connecting groove 560, and further realize the pulling of the fourth elastic member 550. For the lifting member 600, the setting of the protrusion 610 is simple and convenient, easy to process, and can be integrally formed with the lifting member 600 or obtained by secondary processing. In addition, since the protrusion 610 is not fixedly connected to the bottom wall of the connecting groove 560, there is a certain amount of movement space after the lifting member 600 passes through the connecting groove 560, that is, the aforementioned flexible connection. The effect of the flexible connection can refer to the foregoing, and will not be elaborated herein.

[0065] In an alternative embodiment of the present invention, the connection between the lifting member 600 and the fourth elastic member 550 can also be through fastening or a rotating shaft, specifically, it can be adaptively set according to the actual situation.

[0066] Continue to refer to Figure 6, in an alternative embodiment of the present utility model, the lifting member 600 further includes a through groove 620, and the through groove 620 is provided on the side of the protrusion 610 away from the fourth elastic member 550. It can be understood that the provision of the through groove 620 here can make the lifting member 600 easy to bend. In this way, when installing the lifting member 600, the end with the protrusion 610 can be easily passed through the connecting groove 560 to achieve flexible connection.

[0067] Continue to refer to Figure 3 and Figure 4 , in an alternative embodiment of the present utility model, the self-locking member further includes a fifth elastic member 570. The fifth elastic member 570 is provided at the end of the first elastic member 510 away from the second elastic member 520. The fifth elastic member 570 is perpendicular to the first elastic member 510, and the first elastic member 510 is adapted to be fixedly connected to the bracket main body 400 through the fifth elastic member 570.

[0068] It can be understood that if the first elastic member 510 is fixed to the first side plate 430, in order to avoid the inconvenience of installing fasteners, generally the first elastic member 510 needs to be extended along the width direction of the first side plate 430, which will cause an increase in the thickness of the bracket main body 400. For the fifth elastic member 570 provided in this embodiment, since the fifth elastic member 570 is perpendicular to the first elastic member 510, the corner formed between the two can just fit with the connection part of the first side plate 430 and the second side plate 440 on the bracket main body 400. After installation, the fifth elastic member 570 is fixedly attached to the second side plate 440, and the first elastic member 510 is attached to the first side plate 430. In this way, compared with directly fixing the first elastic member 510 to the first side plate 430, it is convenient for the fasteners to pass through and will not affect the volume of the bracket main body 400.

[0069] Figure 7 is a schematic structural diagram of the fixing member provided by the embodiment of the present utility model.

[0070] Refer to Figure 3 and Figure 7, in an alternative embodiment of the present utility model, when the elastic member 500 is only provided at one end of the bracket body 400, the hard disk case 100 further includes a fixing member 700. The fixing member 700 and the elastic member 500 are oppositely arranged at both ends of the second side plate 440. One end of the lifting member 600 is connected to the elastic member 500, and the other end is connected to the fixing member 700. It can be understood that by providing the fixing member 700, it is convenient for the lifting member 600 to apply force, which is convenient for the user's operation. In addition, compared with directly fixing the end of the lifting member 600 far from the elastic member 500 on the bracket body 400, by providing the fixing member 700, it is convenient for the design and manufacture of the bracket body 400, reduces the production difficulty, and the detachable fixing member 700 is easy to replace, which is convenient for later maintenance and inspection.

[0071] Continue to refer to Figure 3 , in an alternative embodiment of the present utility model, one end of the lifting member 600 is flexibly connected to the elastic member 500, and the other end is flexibly connected to the fixing member 700. For the flexible connection between the lifting member 600 and the elastic member 500, please refer to the foregoing description. Similarly, a connection groove is also provided on the fixing member 700. In this case, protrusions 610 and through grooves 620 are respectively provided at both ends of the lifting member 600. It can be understood that by defining that the lifting member 600 is also flexibly connected to the fixing member 700, the conversion of the horizontal force can be further improved, which is convenient for the user to insert and remove the hard disk case 100 in a time-saving and labor-saving manner.

[0072] Refer to Figure 3 and Figure 5 , in an alternative embodiment of the present utility model, mounting grooves 410 and limiting members 420 are provided on the second side plate 440. Mounting grooves 410 are respectively provided at both ends of the second side plate 440. The mounting grooves 410 can be used to mount the elastic member 500 or the fixing member 700. The limiting member 420 is provided at the end for mounting the elastic member 500 and is located above the mounting groove 410 at this end. At least one limiting member 420 is provided. In the figure, the case of providing two limiting members 420 is shown. The two limiting members 420 are relatively spaced apart above the mounting groove 410. The interval between them allows the lifting member 600 to pass through, but can limit the movement of the fourth elastic member 550. It can be understood that by setting it like this, when the pulling force is too large and the fourth elastic member 550 is turned up relative to the bracket body 400, the limiting member 420 can limit the fourth elastic member 550 from continuing to turn up, and the excessive pulling force will be transferred from the fourth elastic member 550 to the limiting member 420. In this way, it can be avoided that the fourth elastic member 550 is excessively pulled and undergoes plastic deformation, and the problem of structural failure of the fourth elastic member 550 caused by plastic deformation can be avoided, and the service life and safety of the fourth elastic member 550 can be improved.
