Description

Geometry reinforcement structure of slide rail

This creation belongs to the field of slide rail structure, especially about a geometric reinforcement structure of a slide rail. By setting a plurality of reinforcement blocks showing geometric shapes at intervals on the middle rail, an interference is formed between two adjacent reinforcement blocks. part, in order to increase the load strength of the outward pull without increasing the cost of materials.

Press, the usual slide rail structure is installed between a cabinet or server bracket and a drawer (or server), used to drive the drawer (or server) to slide linearly relative to the cabinet or server bracket, The slide rail structure is composed of an inner rail, a middle rail, an outer rail and a plurality of sliding elements. The inner rail is locked on the outer surface of the drawer (or server), and the outer rail Lock it on the cabinet or the server bracket. When in use, the drawer (or servo) can be pulled out together with the inner rail, and pulled out together with the middle rail until it is fully expanded, during which, since the middle rail carries the drawer (or servo) ) will be deformed due to the load, so when not in use, the drawer (or the server) must be pushed inward together with the inner rail and the middle rail to fit in the outer rail to avoid subsequent occurrences due to the middle rail Plastic deformation affects the performance and life of the slide rail.

Taking the slide rail dedicated to the server as an example, referring to the testing standard of UL in the United States, it is assumed that the weight of the server case to be loaded is X kg. When testing, the weight of the server case is multiplied by 1.5 times and the total weight of 33 kg is added. The weight (that is, 1.5X+33) is used as the detection standard of its load. Therefore, after the detection standard is established according to the load weight of different server chassis, the detection standard will be increased or decreased. Under this detection standard, After the server chassis drives the slide rails to fully expand outwards, In this case, it must be able to support for more than 1 minute, so that the server chassis will not fall, and the slide rail must also be able to be closed smoothly, so as to meet the safety specifications of the testing standards. Because, when carrying out this test item, the slide rail must be fully extended outwards, and its inner rail is fixed on the outside of the server chassis, and is located in front of the server bracket. At this time, the middle rail is relatively located at the front for fixing the outer rail. The outside of the bracket is the area that is not covered by the front bracket or the outer rail at all. Therefore, the middle rail is easily distorted and deformed by the load in this area, resulting in damage. Therefore, some manufacturers will use additional slide rails The height of the structure is used to increase the tolerance of the vertical force to increase the stability of the structure, but such a reinforcement method will not only increase the manufacturing cost, but also increase the volume and weight relatively, and it will also relatively make the server bracket installable. The reduction in the number of servers will increase the cost of the user and cause inconvenience in use; therefore, how to increase the structural strength of the server slide rails after deployment without changing the height of the server slide rails is an object of the present invention. The problem to be solved. Furthermore, because the installation space of the corresponding server is limited, in fact, this way of increasing the strength will reduce its installation space, resulting in increased difficulty in installation, or the need to adjust the size of the server casing to increase additional production costs. .

For example, the three patent cases of invention patent No. I448262, I578886 and I610639 of the Republic of China all use a reinforcing piece to reinforce the bracket of the slide rail or the slide rail itself to increase the load strength of the slide rail. For example: the I448262 case uses a reinforcing passage between the rail and the extension bracket, and a reinforcing member is inserted in the reinforcing passage to achieve the purpose of improving the structural strength of the rail. Reinforcing effect in space. The I578886 case is a three-section slide rail, a first auxiliary support is provided in a gap formed by the first rail and the second rail, and a second auxiliary support is provided between the second rail and the third rail. A supporting piece and a reinforcing piece, and the purpose of improving the structural strength is achieved by using the first auxiliary supporting piece, the second auxiliary supporting piece and the reinforcing piece. Finally, the I610639 case discloses that a reinforcement gasket is provided on the outside of the first rail, a reinforcing member is provided between the first rail and the second rail, and a support member is provided on the inner surface of the second rail, for The purpose of strengthening the structural strength of the rail is to increase the supporting capacity of the load. After actual testing, the supporting effect obtained by the above method of increasing the structural strength is quite limited, especially for the server chassis above 3U, due to the substantial increase in weight , It usually exceeds the load capacity of the slide rails, especially when it is pulled out of the rack, it is really difficult to effectively support it only by the middle rail, so it is necessary to improve it.

One purpose of this creation is to provide a geometric reinforcement structure of the slide rail, so that the rest of the middle rail overlaps with the inner rail and the outer rail, and a plurality of geometric reinforcements are formed by stamping Blocks, the height of these reinforcing blocks protruding from the surface is between 0.8~1.2mm, so that the reinforcing blocks are arranged at equal intervals along the extension direction of the middle rail to greatly increase the load when pulled out for use The effect of strength.

In order to achieve the above purpose, the geometric figure reinforcement structure of the slide rail in this creation, wherein, the slide rail includes an inner rail, a middle rail, an outer rail and a plurality of sliding elements, and the sliding elements are respectively movable Between the inner rail and the middle rail, and between the middle rail and the outer rail, the inner rail and the middle rail are sequentially pulled out and extended relative to the outer rail, characterized in that: the surface of the middle rail A plurality of reinforcing blocks showing the same geometric shape are formed by stamping, and the reinforcing blocks are arranged at equal intervals along the extending direction of the middle rail, and the gap between the two adjacent reinforcing blocks is made through a configuration means.

In another embodiment, there is a set distance between the two adjacent reinforcing blocks of the invention, and the set distance is between 1.52mm and 2.76mm.
