Description

Technical Field

[0001] The utility model belongs to the technical field of server accessories, in particular to a screw-free quick-locking structure of a riser bracket in a server. Background Art

[0002] A server is a type of computer that runs faster, has a higher load, and is more expensive than an ordinary computer. A server provides computing or application services to other clients (such as PCs, smartphones, ATMs, and even large devices such as train systems) in the network. A server has high-speed CPU computing power, long-term reliable operation, powerful I / O external data throughput, and better scalability.

[0003] At present, in general servers, the rear end of the riser bracket is usually inserted into the guide slot of the die-cast rear window at the rear of the chassis, and the middle part of the bracket is fixed by inserting the gold finger of the riser card locked on it into the motherboard slot. In order to prevent the riser bracket from shaking or tilting during transportation or when it is impacted, a quarter-turn quick-lock screw is fixed on the inner side of the front end of the riser bracket. The lock head of the quick-lock screw can be rotated and locked into the upper limit structure fixed in the corresponding position of the motherboard tray, so as to achieve the fixation of the riser bracket in the general server chassis. However, the current quarter-turn quick-lock screw is relatively expensive on the one hand, and occupies a large space on the other hand, so that the third slot of the riser card can only be inserted with some half-length boards. If a 3 / 4-length card is inserted, it will cause the board to interfere with the quick-lock screw structure. Some raid cards with outlets at the rear can only be inserted when it is evaluated that there is no interference with the quick-lock screw structure. This makes the third slot of the riser have a large restriction on the adaptation of the board. Therefore, the locking structure has the problems of high application cost and restriction on board selection, and the front end fixing method of the riser card bracket needs to be improved and optimized.

The clamping post a and the clamping post b cooperate with each other to clamp and limit the position stop protrusion.

[0013] A further improvement of the present utility model is that a rotating shaft a is provided on the upper part of the caliper body a, and the clamping post a is sleeved and rotatably arranged on the rotating shaft a; a rotating shaft b is provided on the upper part of the caliper body b, and the clamping post b is sleeved and rotatably arranged on the rotating shaft b.

[0031] As attached Figure 6-8 As shown, the riser bracket 30 is provided with a horizontally arranged support plate 31, and two bracket salad holes 311 are provided on the support plate 31; the top surface of the stop spring piece 32 is provided with a spring piece bud 322 that matches the bracket salad hole 311, and the spring piece bud 322 is installed on the support plate 31 through a fastener.

The stop spring piece 32 is an inverted "+"-shaped structure as a whole, and stop protrusions 321 are provided on both sides of the stop spring piece 32. The "+"-shaped structure increases the structural strength of the stop spring piece 32, and the stop protrusions 321 on both sides help prevent it from easily slipping off in the caliper mechanism 40.
