Abstract

The present invention provides a server system and a limiting mechanism used thereby. Through mutual cooperation between the limiting mechanism which sets on a server rack and sliding grooves and limiting holes which are formed in outer side walls of a server case, when internal components of the server case are drawn out, a rear end of the server case can be effectively prevented from turning up or falling down, the problem of case fixation when the server rack uses a tray type sliding rail is solved, the structure is simple and reliable and the practicability is very high.

Claims

1. A limiting mechanism, applied to a server system, the server system having a server rack and a server case, the server rack comprising sliding rails, the sliding rails being oppositely arranged on two sides of the server rack, and the server case being slidably arranged on the sliding rails, and wherein the mechanism comprises:

limiting piece, slidably sitting on the sliding rails, equipped with a convex part on a side surface of the limiting piece towards the server case, equipped with a first barrier portion on a side of the limiting piece towards a rear end of the sliding rail to limit the limiting piece sliding out of the sliding rail;

sliding groove, formed in outer side wall of the server case and located at rear end of the outer side wall of the server case, one end of the sliding groove connecting to the rear end surfaces of the outer side wall of the server case for sliding the convex part into the sliding groove; and

limiting hole, formed in the outer side walls of the server case and located at another end of the sliding grooves, the shape of the limiting holes matching with the shape of the convex part, the convex part to be buckled the limiting holes;

wherein when the server case is mounted on the server rack along the sliding rails, the limiting pieces are driven to relatively slide on the sliding rails, and the convex part slides along the sliding grooves and is buckled in the limiting holes to limit the vertical movement of the server case.

2. The limiting mechanism according to claim 1, wherein the limiting piece further comprises a limiting part and two elastic clamping hooks fixed on the limiting part, and the two elastic clamping hooks are arranged on upper and lower sides of the limiting part, the limiting piece is slidably set on the sliding rail through the two elastic clamping hooks.

3. The limiting mechanism according to claim 2, wherein upper and lower sides of the limiting piece are equipped with two supporting portions respectively corresponding to the two elastic clamping hooks, the two supporting portions are integrally connected with the limiting part, and when the limiting piece slidably sets on the sliding rail, the two supporting portions are clamped on the sliding rail to limit the vertical movement of the limiting part.

4. The limiting mechanism according to claim 3, wherein the two supporting portions are respectively located on inner sides of the two elastic clamping hooks, and when the limiting piece slidably sets on the sliding rail, the elastic clamping hooks are in buckling connection with the sliding rail.

5. The limiting mechanism according to claim 2, wherein the two elastic clamping hooks are connected with the limiting part through a connecting portion.

6. The limiting mechanism according to claim 5, wherein the connecting portion and the limiting part are respectively equipped with fixing holes to connect each other through rivets.

7. The limiting mechanism according to claim 1, wherein the convex part is a rivet part riveted to the limiting piece, the rivet part comprises a rivet cap and a rivet head, the rivet cap penetrates through the limiting part to connect the limiting part, and the rivet head is exposed out of one side of the limiting piece towards the server case.

8. The limiting mechanism according to claim 7, wherein the diameter of the rivet head is smaller than the width of the sliding groove and is not greater than the diameter of the limiting hole, such that when the convex part slides from the notch of one end of the sliding groove to the other end of the sliding groove, the convex part is buckled in the limiting hole through the rivet head.

9. A server system, wherein the server system comprises a server, a server rack equipped with sliding rails and a limiting device, the server is mounted on the server rack through the sliding rails, and the server comprises:

a server case;

a first hard disk component, slidably connected with an inner wall of the server case through a first sliding rail component;

a second hard disk component, slidably connected with the first hard disk component through a second sliding component, the second hard disk component and the first hard disk component being located in parallel in the server case, and the second hard disk component being located at an outlet of the server case; and

the limiting device comprises;

limiting piece, slidably setting on the sliding rails, equipped with a convex part on the side surface of the limiting piece towards the server case, and equipped with a first barrier portion on the side of the limiting piece towards a rear end portion of the sliding rail to limit the limiting piece from sliding out of the sliding rail;

sliding grooves, formed in outer side walls of the server case and located at rear ends of the outer side walls of the server case, one end of the sliding groove connecting to the rear end surfaces of the outer side wall of the server case for sliding the convex part into the sliding groove; and

limiting holes, formed in the outer side walls of the server case and located at another end of the sliding grooves, the shape of the limiting holes matching with the shape of the convex parts to allow the convex parts to be clamped in the limiting holes.

10. The server system according to claim 9, wherein each limiting piece further comprises a limiting part and two elastic clamping hooks fixed on the limiting part, the two elastic clamping hooks are arranged on upper and lower sides of the limiting part, and the limiting piece is slidably set the sliding rail through the two elastic clamping hooks.
