The telescopic mechanism 20 comprises a bolt 21 and a lock catch 22, the bolt 21 and the lock catch 22 are both located in the accommodating space 11, the lock catch 22 is connected with the tray body 10, and the bolt 21 is movable relative to the tray body 10, because the lock catch 22 can be matched with the second end of the bolt 21 and lock the second end of the bolt 21, the bolt 21 can be moved, so that the second end of the bolt 21 moves towards the direction close to the lock catch 22, the bolt 21 can be locked by the lock catch 22, and the first end of the bolt 21 retracts into the through hole; or the locking tongue 21 may be moved so that the second end of the locking tongue 21 moves away from the locking tongue 21, and the first end of the locking tongue 21 extends out of the through hole. Fixed knot constructs 30 and includes shell fragment 31 and trip 32, and the first end at shell fragment 31 is connected to trip 32, and the second end of shell fragment 31 and the interior wall connection of accommodation space 11 are provided with opening 12 on the tray body 10, and under the circumstances that spring bolt 21 removed, spring bolt 21 can extrude shell fragment 31 for the deformation takes place for shell fragment 31. The elastic sheet 31 deforms, and the latch at the first end of the elastic sheet 31 moves along with the elastic sheet, so that at least a part of the hook 32 extends out of the opening 12, or the part of the hook 32 extending out of the opening 12 retracts.

As shown in fig. 4 and 6, under the condition that the lock tongue 21 moves to the first position, the lock tongue 21 extrudes the elastic sheet 31, at this time, the elastic sheet 31 is in a deformation state, the elastic sheet 31 can drive the hook 32 to move, so that at least part of the hook 32 extends out of the opening 12, the part of the hook 32 extending out of the opening 12 can be clamped with the fixing part 201, so that the tray body 10 is fixed relative to the server case 200, thereby avoiding the situation that the tray body 10 is inside the server case, the server case 200 shakes under the action of external force, and the phenomenon that the tray body 10 breaks away from the server case 200 occurs.

As shown in fig. 2, when the latch bolt 21 moves to the second position, the latch bolt 21 is separated from the elastic sheet 31, at this time, the elastic sheet 31 returns to the original state, and the elastic sheet 31 drives the portion of the hook 32 extending out of the opening 12 to retract, so that the hook 32 is separated from the fixing portion 201, and thus the fixing of the tray body 10 can be cancelled, and the tray body 10 can move relative to the server chassis 200, i.e., the tray body 10 can be pulled out from the server chassis 200.

It should be noted that, under the condition that the telescoping mechanism 20 includes the lock tongue 21 and the lock catch 22, and the number of the telescoping mechanisms 20 is 2, the fixing structures 30 may be disposed at 2 telescoping mechanisms 20, and each lock tongue 21 moves to press 1 elastic sheet 31, so that 1 elastic sheet 31 deforms.

In addition, in some embodiments, as shown in fig. 5, the inner wall of the accommodating space 11 may have a mounting surface 101, the elastic sheet 31 is connected to the mounting surface 101, and a preset included angle is formed between a plane where the elastic sheet 31 is located and the mounting surface 101, and when the latch 21 moves relative to the tray body 10, the size of the preset included angle changes; under the condition that the lock tongue 21 moves to the first position, the numerical value of the preset included angle is a first numerical value; under the condition that the lock tongue 21 moves to the second position, the numerical value of the preset included angle is a second numerical value; wherein the first value is less than the second value.

The inner wall of accommodation space 11 has installation face 101, and shell fragment 31 can connect on installation face 101 to make and have the contained angle of predetermineeing between the plane at shell fragment 31 place and the installation face 101, when the relative tray body 10 of spring bolt 21 removed, spring bolt 21 removed along installation face 101, can produce the extrusion to spring bolt 21, make the size change of the contained angle of predetermineeing between the plane at shell fragment 31 place and the installation face 101.

Under the circumstances that spring bolt 21 removed to the first direction, spring bolt 21 extrudees shell fragment 31, shell fragment 31 removes to the direction that is close to installation face 101 under the effect of spring bolt 21, under the circumstances that spring bolt 21 removed to the first position, the angle of predetermineeing the contained angle is first numerical value, shell fragment 31 is located the position that is close to installation face 101 this moment, and connect the trip 32 at the first end of shell fragment 31 and have at least part to stretch out in opening 12, thereby tray body 10 can be connected with fixed part 201 through trip 32, the realization is fixed to tray body 10, in order to avoid tray body 10 under the condition that is in server box inside, server machine case 200 produces under the exogenic action and rocks, make the phenomenon that tray body 10 breaks away from in server machine case 200 take place.

Under the condition that the bolt 21 moves towards the second direction, the bolt 21 reduces the extrusion on the elastic sheet 31, and the elastic sheet 31 moves towards the direction far away from the installation surface 101 under the action of the bolt 21, so that the buckle is driven to move towards the direction far away from the installation surface 101. Under the condition that the bolt 21 moves to the second position, the angle of the preset included angle is a second numerical value, at the moment, the elastic sheet 31 is located at a position far away from the installation surface 101, the part extending out of the opening 12 can be withdrawn from the opening 12, so that the hook 32 is retracted into the tray body 10, the hook 32 is separated from the fixing part 201, the tray body 10 can move relative to the server case 200, the telescopic mechanism 20 can drive the tray body 10 to move, and the tray body 10 can be pulled out from the server case 200.

The first direction is a direction from the lock tongue 21 to the lock catch 22, the second direction is opposite to the first direction, and the second direction is a direction from the lock catch 22 to the lock tongue 21. When the locking bolt 21 moves in the first direction, the locking bolt 21 moves close to the lock catch 22, that is, the locking bolt 21 moves in a direction of retracting inwards the through hole; when the latch bolt 21 moves in the second direction, the latch bolt 21 moves away from the lock catch 22, i.e. the latch bolt 21 moves in a direction extending outward from the through hole.

It should be noted that a preset included angle is formed between the plane where the elastic piece 31 is located and the mounting surface 101, and the size of the preset included angle changes when the lock tongue 21 presses the elastic piece 31 to deform the elastic piece 31, for example, the larger the size of the preset included angle is, the larger the deformation amount generated by the elastic piece 31 when the lock tongue 21 presses the elastic piece 31 is. The preset included angle may be set according to a use requirement, such as a movable distance of the lock tongue 21, a size of the elastic sheet 31 in the preset direction, and the like, for example, the size of the preset included angle may be 3 °, 5 °, 7 °, 10 °, and the like, and the embodiment of the present invention is not particularly limited to the size of the preset included angle. The first value is an included angle between a plane where the elastic sheet 31 is located and the mounting surface 101 when the lock tongue 21 presses the elastic sheet 31, the size of the first value can determine how much the hook 32 extends out of the opening 12, the first value can be 0, 1 degree, 2 degrees and the like, and for the size of the first value, the embodiment of the invention is not particularly limited as long as the hook 32 can extend out of the buckle and be clamped in the fixing part 201; the second value may determine the amount of the portion of the hook 32 retracted from the outside of the tray 100, and the second value may be the same as the value of the preset included angle, that is, the clip is completely retracted from the opening 12, and the elastic sheet 31 is restored to be deformed in the original state, or the second value may be slightly smaller than the value of the preset included angle, and the embodiment of the present invention is not particularly limited as long as the hook 32 can be retracted from the opening 12 and separated from the fixing portion 201.

It should be further noted that, as shown in fig. 5, the elastic sheet 31 may be "U" shaped, that is, the elastic sheet 31 has two support rods extending in a preset direction, and the lock tongue 21 abuts against the two support rods of the "U" shaped elastic sheet 31 in the moving process, so that the elastic sheet 31 is deformed by applying force to the two support rods, and compared with the rectangular elastic sheet 31, the elastic sheet 31 can be deformed by a smaller force, which is convenient for operation. In addition, the width of the position of the locking tongue 21 close to the second end may be smaller than the distance between the two support rods, the distance between the two support rods is the distance between one of the support rods and the other support rod, the width of the locking tongue 21 is the size of the locking tongue 21 in the distance direction of the two support rods, so that the locking tongue 21 is unlocked by the lock catch 22, and under the condition that the locking tongue 21 moves in the second direction, the position of the locking tongue 21 close to the second end is prevented from pressing the elastic sheet 31, so that the elastic sheet 31 can recover the deformation. That is, after the position where the width of the lock tongue 21 is greater than or equal to the distance between the two support rods leaves the two support rods, the lock tongue 21 can cancel the extrusion of the two support rods, and the lock tongue 21 is in a state of extruding the elastic sheet 31 all the time after the lock catch 22 releases the lock on the lock tongue 21, so that the problem that the elastic sheet 31 cannot recover to deform to release the lock on the tray body 10 occurs, or the problem that the lock tongue 21 cancels the extrusion of the elastic sheet 31 when the lock tongue 21 needs to be moved to be completely separated from the elastic sheet 31 after the lock catch 22 releases the lock on the lock tongue 21 can be prevented.

Or, the elastic sheet 31 may also be "L" shaped or "I" shaped, that is, the elastic sheet 31 has a supporting rod extending in a preset direction, and the bolt 21 abuts against one supporting rod of the elastic sheet 31 in the moving process, so as to apply force to the one supporting rod to deform the elastic sheet 31, thereby further reducing the force required to deform the elastic sheet 31. Correspondingly, the position of the locking tongue 21 close to the second end can be dislocated with the supporting rod, so that when the locking tongue 21 moves towards the second direction, the position of the locking tongue 21 close to the second end can cancel the extrusion on the elastic sheet 31. Of course, the elastic sheet 31 may also have other shapes, and the embodiment of the present invention is not limited in detail herein.

In addition, in some embodiments, as shown in fig. 5, the second end of the elastic sheet 31 may be provided with a connecting piece 33, the connecting piece 33 is connected with the inner wall of the accommodating space 11, and the connecting piece 33 is located between the locking tongue 21 and the inner wall of the accommodating space 11.

Because the second end of the elastic sheet 31 is provided with the connecting piece 33, the elastic sheet 31 can be connected through the connecting piece 33, so that the connection between the elastic sheet 31 and the inner wall of the accommodating space 11 is stable. The connecting piece 33 is located between the lock tongue 21 and the inner wall of the accommodating space 11, so that when the lock tongue 21 moves relative to the tray body 10, the lock tongue 21 can move towards the surface of the lock tongue 21 against the connecting piece 33, and the lock tongue 21 can press the elastic sheet 31 in the moving process, so that the elastic sheet 31 can move along the hook 32.

It should be noted that, in order to facilitate the connection between the elastic sheet 31 and the connecting member 33, and the connecting member 33 is used to connect the elastic sheet 31 and the inner wall of the accommodating space 11, the elastic sheet 31 and the connecting member 33 may be manufactured in an integrated manner, that is, the elastic sheet 31 and the connecting member 33 are integrated, and both the elastic sheet 31 and the connecting member 33 have elasticity. Of course, the elastic sheet 31 and the connecting member 33 may also be made in other manners, for example, the elastic sheet 31 and the connecting member 33 are two parts, and then the connecting member 33 is connected to the second end of the elastic sheet 31 by welding, adhering, and the like, which is not limited in the embodiment of the present invention.

The second method comprises the following steps: the fixing structure 30 may include an elastic protrusion, the elastic protrusion is disposed on a surface of the tray body 10 away from the accommodating space 11, and when the telescopic structure is in a contracted state, the elastic protrusion is clamped with the fixing portion 201, and the tray body 10 is fixed relative to the server chassis 200; in the case where the telescopic structure is in the extended state, the elastic protrusions are separated from the fixing portions 201, and the tray body 10 is movable with respect to the server chassis 200.
