Description

Technical Field

[0001] The present invention relates to the technical field of servers, and particularly relates to a drawer-type server safety lock system. Background Art

[0002] With the continuous development of big data technology and cloud computing technology, high-performance storage and servers are widely demanded. The drawer-type server is a typical structure of high-end storage servers. As Figure 1 shown, multiple 2-nodes are arranged in layers. When needed, they can be pulled out like a drawer and separated from the chassis 1. Due to high functional requirements and large weight of each 2-node, there are safety hazards during the operation and maintenance of the drawer-type server.

[0003] Safety hazard 1: When the server chassis is touched by the staff, some of the partially pulled-out nodes may slide out of the 1 server chassis by themselves and fall to the ground. Safety hazard 2: Due to the large weight of the 2-node, when the staff suddenly pulls out the 2-node, if they react in time or cannot support it, the distal end of the 2-node is likely to fall to the ground or injure the staff.

[0004] The technical solutions adopted in the current market are to set reminder signs on the surface of the 2-node to remind the staff, but the actual effect is not ideal. Therefore, it is imperative to design a reliable safety lock system to eliminate the safety hazards of the drawer-type server. Summary of the Invention

[0005] In view of the problems such as safety hazards existing when the 2-node of the current drawer-type server is pulled out, the present invention proposes a drawer-type server safety lock system.

[0006] The present invention proposes a drawer-type server safety lock system, including a chassis and a node slidably disposed in the chassis. A safety lock assembly is provided on the inner wall of the chassis, and an unlocking assembly is provided on the base of the node. The safety lock assembly includes a first fixing member, a locking hook and a first torsion spring. One side of the first fixing member is fixed to the inner wall of the chassis, and the other side of the first fixing member is rotatably provided with the locking hook. The locking hook is provided with the first torsion spring. The chassis is provided with a first slot. Under the action of the torsion of the first torsion spring, the end of the locking hook extends out of the first slot. The unlocking assembly includes a second fixing member, a strip-shaped unlocking key and a second torsion spring. One side of the second fixing member is fixed to the base of the node. The middle part of the strip-shaped unlocking key is rotatably provided on the other side of the second fixing member. One end of the strip-shaped unlocking key is a button end, and the other end is a follower end. The outer wall of the node is provided with a second slot and a third slot.

The middle part of the strip-shaped unlocking key is provided with the second torsion spring, and the second torsion spring can give the strip-shaped unlocking key a torsion force to rotate towards the outside of the third slot.

[0007] Preferably, the node includes an inserted state and a withdrawn state. When the node is in the inserted state, under the action of the outer wall of the node, the end of the locking hook is pushed into the inner wall of the chassis through the first slot hole, and the node is freely inserted into the chassis; when the node is in the withdrawn state, the end of the locking hook first slides over the outer wall of the node and is snapped into the second slot hole under the action of the first torsion spring.

[0008] Preferably, in the state where the end of the locking hook is snapped into the second slot hole, when the button end is pressed, the strip-shaped unlocking key rotates around the second fixing member, the button end moves into the third slot hole, the follower end moves out of the second slot hole and pushes the end of the locking hook away from the second slot hole. In the state where the end of the locking hook leaves the second slot hole, the node can be withdrawn from the chassis.

[0009] Preferably, a first rotating shaft is fixed on one side of the first fixing member, and the locking hook is rotatably arranged on the first rotating shaft; a second rotating shaft is fixed on one side of the second fixing member, and the middle part of the strip-shaped unlocking key is rotatably arranged on the second rotating shaft.

[0010] Preferably, the button end is provided with a limiting step, and the limiting step can limit the movement of the button end out of the first groove.

[0011] Preferably, a first groove is provided at a position on the outer wall of the node opposite to the button end, and the third slot hole is arranged at the bottom of the first groove. Under the action of the torsion of the second torsion spring, the limiting step abuts against the third slot hole and the button end is located in the first groove.

[0012] Preferably, a sliding inclined surface is provided on the side of the end of the locking hook away from the first fixing member. When the node is in the inserted state, the outer wall of the node is in sliding contact with the sliding inclined surface to push the end of the locking hook into the inner wall of the chassis through the first slot hole.

Detailed implementation manner

[0026] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0027] As Figures 1 to 4 shown, in this embodiment, the present invention provides a drawer-type server security lock system, including a chassis 1 and a node 2 slidably disposed in the chassis 1. A security lock assembly is provided on the inner wall of the chassis 1, and an unlocking assembly is provided on the base of the node 2. Among them, the security lock assembly includes a first fixing member 3, a locking hook 4, and a first torsion spring 5. One side of the first fixing member 3 is fixed to the inner wall of the chassis 1, and the other side of the first fixing member 3 rotatably disposes the locking hook 4. The locking hook 4 is provided with a first torsion spring 5. The chassis 1 is provided with a first slot hole 6. Under the action of the torsion of the first torsion spring 5, the end of the locking hook 4 extends out of the first slot hole 56. The unlocking assembly includes a second fixing member 7, a strip-shaped unlocking key 8, and a second torsion spring 9. One side of the second fixing member 7 is fixed to the base of the node 2. The middle of the strip-shaped unlocking key 8 is rotatably disposed on the other side of the second fixing member 7. One end of the strip-shaped unlocking key 8 is a button end 10, and the other end is a follower end 11. The outer wall of the node 2 is provided with a second slot hole 12 and a third slot hole 13. The follower end 11 is disposed at the second slot hole 12, and the button end 10 is disposed at the third slot hole 13. The middle of the strip-shaped unlocking key 8 is provided with a second torsion spring 129, and the second torsion spring 129 can give the strip-shaped unlocking key 8 a torsion force to rotate towards the outside of the third slot hole 13.

[0028] During normal use, the server usually includes two different states, namely the inserted state and the extracted state of Node 2. When Node 2 is in the inserted state - that is, during the process when the operator grabs Node 2 by hand and inserts it into the chassis 1, under the action of the outer wall of Node 2, the end of the locking hook 4 is pushed into the inner wall of the chassis 1 through the first slot 6, and Node 2 is freely inserted into the chassis 1; when Node 2 is in the extracted state - that is, during the process when the operator grabs Node 2 by hand and extracts it, the end of the locking hook 4 first slides over the outer wall of Node 2 and is snapped into the second slot 12 under the action of the first torsion spring 5. When the end of the locking hook 4 is snapped into the second slot 12, there will be a stutter in sound and movement, reminding the operator that Node 2 is about to be completely extracted from the chassis 1. Under this reminder, the operator will grasp Node 2 with both hands; in the state where the end of the locking hook 4 is snapped into the second slot 12, Node 2 cannot be extracted from the chassis 1. At this time, the operator presses the button end 10, and the strip-shaped unlocking key 8 rotates around the second fixing member 7. The button end 10 moves into the third slot 13, and the follower end 11 moves out of the second slot 12 and pushes the end of the locking hook 4 out of the second slot 12. In the state where the end of the locking hook 4 leaves the second slot 12, Node 2 can be extracted from the chassis 1. To prevent the follower end 11 from moving outward and entering the first slot 6 and getting stuck with the chassis 1 again, the maximum dimension of the follower end 11 is greater than the maximum dimension of the first slot 6.

[0029] Specifically, as Figures 2 to 4 shown, a first rotating shaft 14 is fixed on one side of the first fixing member 3, and the locking hook 4 is rotatably arranged on the first rotating shaft 14; a second rotating shaft 15 is fixed on one side of the second fixing member 7, and the middle part of the strip-shaped unlocking key 8 is rotatably arranged on the second rotating shaft 15.

[0030] To more smoothly and labor-savingly push Node 2 into the chassis 1, a sliding inclined surface 16 is arranged on the side of the end of the locking hook 4 away from the first fixing member 3. When Node 2 is in the inserted state, the outer wall of Node 2 is in sliding contact with the sliding inclined surface 16 to push the end of the locking hook 4 into the inner wall of the chassis 1 through the first slot 6. The existence of the sliding inclined surface 16 can save the force used by the operator to push Node 2 into the chassis 1.

[0031] As Figures 3 to 4 shown, the button end 10 is provided with a limiting step 17. A first groove 18 is arranged at the position on the outer wall of Node 2 opposite to the button end 10. The third slot 13 is arranged at the bottom of the first groove 18. The limiting step 17 can limit the movement of the button end 10 out of the first groove 18. Under the torque of the second torsion spring 9, the limiting step 17 is closely attached to the third slot 13 and the button end 10 is located in the first groove 18.

[0032] A second groove 19 is provided at a position on the outer wall of the node 2 facing the second fixing member 7, and a rotating hole 20 is opened at the bottom of the second groove 19; the strip-shaped unlocking key 8 is provided with a rotating shaft fixing ring 21, the second rotating shaft 15 is rotatably arranged in the rotating shaft fixing ring 21, and the rotating shaft fixing ring 21 extends out through the rotating hole 20 and is located in the second groove 19.

[0033] To enable the node 2 to be inserted more smoothly without getting stuck during the insertion process, the second groove 19 can be set to have a rounded corner, and the outer side surface of the rotating shaft fixing ring 21 is also set to be a curved surface. When the node 2 is in the pulled-out state, the end of the locking hook 4 can smoothly slide over the second groove 19 and the rotating shaft fixing ring 21 and be caught in the second slot 12.

[0034] As Figures 2 to 4 shown, the working principle of this drawer-type server security lock system is as follows:

[0035] First, when the chassis 1 is separated from the node 2, in the security lock assembly: due to the torsion force of the first torsion spring 5, the locking hook 4 is pressed against the first slot 6 and the end of the locking hook 4 extends out of the first slot 6; in the unlocking assembly: due to the torsion force of the second torsion spring 9, the button end 10 of the strip-shaped unlocking key 8 is pressed against the third slot 13, and at the same time, the follower end 11 is located in the second slot 12, and due to the limiting effect of the limiting step 17, the follower end 11 cannot be pressed into the second slot 12.

[0036] When the node 2 is inserted into the chassis 1: the node 2 is pushed against the sliding inclined surface 16 of the locking hook 4, and the locking hook 4 retracts into the inner wall of the chassis 1 under pressure, and the node 2 is smoothly inserted into the chassis 1.

[0037] When the node 2 is pulled out of the chassis 1: due to the torsion force of the second torsion spring 9, the locking hook 4 cannot push open the button end 10 of the strip-shaped unlocking key 8, and the node 2 can slide through smoothly. Due to the rounding effect of the first groove 18 and the second groove 19 and the guiding effect of the curved surface of the outer side surface of the rotating shaft fixing ring 21, the locking hook 4 smoothly slides over the surface, and the node 2 is smoothly pulled out of the chassis 1.

[0038] When the security lock takes effect when the node 2 is about to be completely pulled out: when the end of the locking hook 4 slides to the second slot 12, due to the torsion force of the first torsion spring 5, the end of the locking hook 4 is caught in the second slot 12, and there is a sound and a movement jam here, reminding the operator that the node 2 is about to be completely pulled out of the chassis 1.

[0039] Unlocking operation when the node 2 is pulled out: Hold the end position of the node 2 with your hand, and at the same time press the button end 10 with your finger. The follower end 11 of the strip-shaped unlocking key 8 pushes the end of the locking hook 4 out of the second slot 12. At this time, the unlocking operation is completed, and the node 2 can be completely pulled out of the chassis 1.

[0040] It can be seen from the above embodiments that the beneficial effects of the present invention are:

[0041] 1. The present invention solves the security hazards of drawer-type servers in operation and maintenance services through a safety lock system, improving the personal safety of equipment and operators.

[0042] 2. The present invention combines the hand-grip node 2 and the unlocking action into one through an unlocking component, simplifies the operation action, facilitates quick unlocking, forcibly corrects the position of the hand-grip node 2 into the correct posture with one in front and one behind, and prevents the node from falling.

[0043] 3. The present invention forms a safety lock through a torsion spring and a buckle structure, which can not only ensure smooth insertion of the node but also prevent the node from being accidentally completely pulled out; the spatial displacement and direction conversion of the strip-shaped unlocking key 8 are realized through a seesaw structure, and the unlocking operation is convenient and fast; an unlocking device is formed by a second torsion spring 9 and the strip-shaped unlocking key 8, which can not only ensure smooth insertion of the node 2 but also reserve enough space for the safety lock to take effect when the node 2 is pulled out.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
