Description

Fixing device arranged on upper cover of case and server

Technical Field

The invention relates to the field of servers, in particular to a fixing device arranged on an upper cover of a case and a server.

Background

In the prior art, two modes are adopted for fixing the upper cover of the server in the server and server products. One is to directly lock the upper cover and the chassis together by screws for products which do not need to be maintained by opening the upper cover, and although the design has high reliability, the mode that dozens of screws are required to be removed by tools for opening the chassis is more acceptable for customers. With the increasing importance of fast operation and maintenance and better operation friendliness of market customers, another way of fixing the upper cover through a tool-free upper cover locking device is increasingly used in server products. The upper cover locking device utilizes the reaction force between the upper cover locking device and the fixing pin at the corresponding position of the chassis to enable the upper cover to move forwards to the designated position. And the two sides of the case are matched by adopting a matching structure of a positioning pin and a gourd hole. Specifically, the positioning pins are additionally arranged on the upper cover, semicircular gourd holes are formed in the two sides of the case, and the positioning pins are hung in the gourd holes to lock the upper cover.

Because one side of the gourd hole is open, when one side of the case is lifted, the case is deformed greatly, and particularly when one corner is lifted, the hidden trouble that the upper cover of the case is automatically bounced open is caused. When the case warp greatly, lead to atress such as integrated circuit board unusual easily, functional hidden danger appears.

According to an aspect of the present invention, an embodiment of the present invention provides a fixing device disposed on an upper cover of a chassis, as shown in fig. 1, including an upper cover lock 1, a base 2, a first slider 3, and a guide bar 4.

In some embodiments, as shown in fig. 2 and 3, when the cover lock 1 is not closed, the tail end link 12 does not protrude, and when the cover lock 1 is closed, the tail end link 12 protrudes to a portion, and the protruding portion pushes the first slider 3. In the embodiment of the present invention, the cover lock 1 may be a tool-free cover lock device commonly used in the prior art, and the specific structure thereof will not be described in detail herein.

In some embodiments, as shown in fig. 4 and 5, the base 2 may include an upper base 21 and a lower base 22 with a gap between the upper base 21 and the lower base 22.

The two sides of the upper base 21 are provided with first inclined surfaces 211, an included angle between the first inclined surfaces 211 and the top surface of the upper base 21 is an acute angle, and the lower base 22 is provided with a groove 221;

in some embodiments, as shown in fig. 4 and 5, the first slider 3 may be disposed in the groove 221.

Wherein, the first sliding block 3 has a second inclined surface 31, and an included angle between the second inclined surface 31 and the top surface of the lower base 21 is an obtuse angle

In some embodiments, as shown in fig. 4 and 5, one end of the guide rod 4 is disposed in the gap, the one end of the guide rod has a first sliding surface 41 slidably engaged with the first inclined surface and a second sliding surface 42 slidably engaged with the second inclined surface, and the other end of the guide rod 4 is provided with a pin 43.

Wherein, at the closed in-process of upper cover lock 1, connecting rod 12 of upper cover lock tail end can slowly stretch out along with handle 11 rotation closure, and the first slider 3 of connecting rod 12 promotion backward stretching out moves backward, and first slider 3 then removes and predetermines after the distance, can laminate with second glide plane 42, then extrudees the one end of guide arm 4 through second inclined plane 31 to make 4 lateral motion of guide arm, thereby make the pin 43 of the other end of guide arm 4 hang into round hole 61. That is, the connecting rod 12 pushes the first slider 3 to slide along the first direction to drive the guide rod to slide along the second direction, so that the movement of the upper cover 5 along the length direction of the chassis is transferred to the guide rod through the first slider, the upper cover 5 can relatively slide between the upper cover 5 and the box 6 under the action of the upper cover lock 1, and the movement of the upper cover 5 along the width direction of the chassis is transferred to the movement of the guide rod 4 along the width direction of the chassis, by using the triangle principle, the very small movement stroke of the tool-free upper cover lock is enlarged, so that the pin 43 connected with the guide rod 4 is matched with the round hole 61 on the inner side wall of the box 6, and a backward-preventing constraint is added to the open other side of the original gourd-shaped hole 62 (L-shaped groove), thereby solving the problem that the upper cover lock fails due to large distortion and deformation when the server is moved, the upper cover and the chassis are locked, the structure is stable, and deformation is not easy to cause deformation, and the board card inside the chassis can be effectively protected, and the functional hidden danger due to stress abnormality caused by the deformation of the chassis can be avoided.

The scheme provided by the invention can effectively fix the upper cover and the case completely through the traditional pressing and unlocking mode of the upper cover lock, and ensures a very good operation friendliness and an efficient operation and maintenance mode on the premise of realizing the structural function.

In some embodiments, the fixing means comprise two guide rods 4, said two guide rods 4 being located on either side of the base 2. Like this, through setting up two guide arms 4 to realize that the central axis symmetry sets up, avoid the upper cover to take place and offset about or from beginning to end.

In some embodiments, further comprising:

and one end of the return spring 7 is connected with one end of the guide rod 4, and the other end of the return spring is fixed in the gap or is connected with one end of the other guide rod 4.

In some embodiments, the return spring 7 is in tension.

Specifically, as shown in fig. 5, the left and right guide rods can be reset by two springs or one spring, and since the reset spring is in a stretching state, when the upper cover lock is opened, the guide rod 4 is pulled towards the middle under the action of the spring, so that the pin 43 at the other end of the guide rod 4, which is matched with the box body, is pulled out of the round hole 61.

In some embodiments, further comprising:

and a stop device 8 arranged in the gap to limit the position of the guide rod 4 in the gap.

Based on the same inventive concept, the embodiment of the present invention further provides a server, which includes a box body 6 and an upper cover 5, wherein the upper cover 5 includes:

an upper cover lock 1;

a base 2 including an upper base 21 and a lower base 22, a gap being provided between the upper base 21 and the lower base 22; the two sides of the upper base 21 are provided with first inclined surfaces 211, an included angle between the first inclined surfaces 211 and the top surface of the upper base 21 is an acute angle, and the lower base 22 is provided with a groove 221;
