Description

Technical Field

[0001] The utility model relates to the technical field of hard disk placement drawers, in particular to a hard disk drawer locking structure. Background Art

[0002] After the server cabinet is assembled, a variety of electronic devices need to be placed in the inner cavity of the cabinet, among which hard disks are relatively more core devices. In the existing technology, when placing the hard disk, the hard disk is placed in a drawer structure, and then the drawer structure and the cabinet are plugged and connected, and then the drawer and the cabinet are locked. In the existing technology, the drawers are locked by directly tightening long-head bolts in the threaded holes on the side of the cabinet. In actual use, the tightening force after the locking is completed is huge, which leads to the need for great effort to complete the subsequent disassembly. In addition, after the existing locking structure is locked by bolts, the bolts will loosen after the cabinet has been in operation for a long time, and the drawer will vibrate, resulting in abnormal noise. For this reason, it is urgent to develop a locking structure that is easy to disassemble and ensure that no abnormal noise will be generated even if the subsequent bolts vibrate. Summary of the Invention

[0003] In view of the above problems, the present invention provides a hard disk drawer locking structure, which is easy to assemble and disassemble and ensures that no abnormal noise will occur even if subsequent bolts vibrate.

DETAILED DESCRIPTION

[0021] A hard disk drawer locking structure, see Figure 1-Figure 3 : It includes a box body 10 and at least four sets of locking components 20; in a specific implementation, the box body 10 includes a drawer body 30 and a front end cover 11, and the front end of the drawer body 30 is open and covered with the front end cover 11;

[0022] Each locking assembly 20 includes a locking bolt 40 and a linear spring 50;

[0023] The two sides of the drawer body 30 corresponding to the front cover 11 are respectively convex to form a left front locking stop 31 and a right front locking stop 32. The left front locking stop 31 is sequentially provided with four groups of locking positioning holes 33 from top to bottom, and the right front locking stop 32 is sequentially provided with three groups of locking positioning holes 33 from top to bottom. Each group of locking positioning holes 33 corresponds to a group of locking components 20.

[0024] The threaded end 41 of the locking bolt 40 passes through the linear spring 50, and the front end of the linear spring 50 is arranged in close contact with the rear surface of the bolt head 42 of the locking bolt 40. The threaded end 41 of the locking bolt 40 passes through the locking positioning hole 33 and is threadedly connected to the corresponding threaded hole on the cabinet. The equivalent outer diameter of the linear spring 50 is larger than the locking positioning hole 33, and the rear end of the linear spring 50 is arranged in close contact with the front facade of the left front end locking stop 31 and the right front end locking stop 32.

[0025] In a specific implementation, a locking hole 34 is provided below the locking positioning holes 33 of the left front end locking stop 31 corresponding to the first height position and the third height position. The locking hole 34 is directly fastened to the cabinet through a locking bolt, which ensures stable and reliable locking.

[0026] A locking hole 34 is provided below the locking positioning holes 33 of the right front end locking stop 32 corresponding to the first height position and the second height position. The locking hole 34 is directly fastened to the cabinet via a locking bolt, which ensures stable and reliable locking.

[0027] In a specific implementation, the outer periphery of the bolt head 42 of the locking bolt 40 is provided with anti-slip grooves 43 , and the end surface of the threaded head 42 of the locking bolt 40 is provided with a cross groove 44 .

[0028] Its working principle is as follows: after the drawer body is positioned into the cabinet through rail insertion, the front end stop positioning is formed by the front end locking stops on both sides. After that, the front end stop positioning on both sides is completed and locked to the cabinet through locking bolts and linear springs respectively. The linear spring presses the front end stop positioning on the corresponding front facade of the cabinet, and the locking bolt does not need to contact the facade with the facade of the front end stop positioning, which makes locking time-saving and labor-saving, and subsequent disassembly and assembly is time-saving and labor-saving. In addition, after the cabinet has been in operation for a long time, the bolts will become loose. Under the gap compensation of the linear spring, the front end locking stop is close to the corresponding front facade of the cabinet, and no vibration gap will occur. It is easy to disassemble and assemble, and ensures that no abnormal noise will occur even if the subsequent bolts vibrate.
