Referring to fig. 1, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention.

In one embodiment of the present invention, the adjustable dimension support frame mainly comprises a mounting rail 2, a telescopic pressing plate 3 and an elastic member 4.

Wherein, installation guide rail 2 sets up the both sides lateral wall position at the cabinet body 1 simultaneously, and each installation guide rail 2 all links to each other with the stand that the cabinet body 1 was reserved to realize the stable connection of installation guide rail 2 in the cabinet body 1. The mounting rails 2 are mainly used to support both sides of the bottom surface of the server a, to support the server a on both sides, and to allow the server a to slide on the surface of the mounting rails 2 in the longitudinal direction (mounting direction) to adjust the mounting depth position in the cabinet 1.

As shown in fig. 2 and 3, fig. 2 is a schematic structural diagram of the telescopic press plate 3 pressing the side wall of the server a, and fig. 3 is a schematic diagram of a change of the telescopic state of the telescopic press plate 3.

The extendable platen 3 is provided on each of the mounting rails 2, has a long-strip shape, extends in the longitudinal direction of the mounting rail 2, and is slidable in the width direction (lateral direction) of the mounting rail 2 on the surface of the mounting rail 2, and is configured to be held from both sides in the width direction of the server a by abutting the inner side surface thereof against the side walls on both sides of the server a supported by the mounting rail 2.

The elastic pieces 4 are connected between the installation guide rail 2 and the telescopic pressing plate 3, a plurality of elastic pieces are generally arranged between the installation guide rail 2 and the telescopic pressing plate 3 at the same time, and the elastic deformation direction (namely the telescopic direction) of each elastic piece 4 is the width direction of the installation guide rail 2, and the elastic pieces are mainly used for pressing the telescopic pressing plate 3 on the side wall of the server a through the elastic pre-tightening force formed by the elastic pieces on the telescopic pressing plate 3 along the transverse direction.

Compared with the prior art, the support frame of different specifications need not to be torn open again to this embodiment, can realize the commonality to the server a of different width dimension, guarantees the stable installation of the server a of different width dimensions in the rack.

As shown in fig. 4, fig. 4 is a schematic view of the installation structure of the elastic member 4 between the installation rail 2 and the telescopic pressing plate 3.

In order to facilitate the connection of the elastic member 4 between the mounting rail 2 and the telescopic pressing plate 3, a vertical plate 21 is added in the present embodiment. Specifically, the vertical plate 21 is disposed outside the mounting rail 2 and extends along the length direction of the mounting rail 2, and the length thereof may be equivalent to the length of the mounting rail 2. So set up, the overall structure of installation guide 2 and riser 21 forms "L" type, and flexible clamp plate 3 sets up on installation guide 2's surface promptly, and simultaneously, the medial surface at riser 21 and the lateral surface of flexible clamp plate 3 are connected respectively at the both ends of each elastic component 4, keeps the elastic direction to be the width direction of installation guide 2. Furthermore, the elastic elements 4 are generally distributed along the length direction of the mounting rail 2, so that an elastic pre-tension is formed on the telescopic pressing plate 3 over the entire length thereof.

Each elastic member 4 is generally a spring, but an elastic column, an elastic sheet, or the like may be used.

Furthermore, in order to facilitate the connection and positioning of each elastic element 4 between the vertical plate 21 and the telescopic pressing plate 3, a guide post 5 is additionally arranged in the embodiment. Specifically, this guide post 5 sets up corresponding position department on the medial surface of riser 21 and the lateral surface of flexible clamp plate 3, and simultaneously, guide post 5 extends, protruding along the width direction of installation guide rail 2, is generally provided with a plurality ofly simultaneously, and each guide post 5 respectively along riser 21 and the length direction evenly distributed of flexible clamp plate 3.

As shown in fig. 5 and 6, fig. 5 is an exploded view of the telescopic pressing plate 3 and the mounting rail 2, and fig. 6 is a view illustrating a matching structure of the positioning post 22 and the long sliding hole 32.

In order to facilitate the transverse (width direction) sliding of the telescopic pressing plate 3 on the mounting rail 2, a sliding connection plate 31, a long sliding hole 32 and a positioning column 22 are additionally arranged in the embodiment. The sliding connection plate 31 is disposed at the bottom of the telescopic pressing plate 3, extends along the length direction of the telescopic pressing plate 3, and is mainly used for being tightly attached to the surface of the installation guide rail 2. The long slide holes 32 are provided in the slide connection plate 31, and are generally provided in plural numbers, and each long slide hole 32 is distributed along the longitudinal direction of the slide connection plate 31, and each long slide hole 32 extends along the width direction of the mounting rail 2. Correspondingly, the positioning columns 22 are vertically arranged on the surface of the mounting rail 2, and are generally arranged in a plurality of numbers, and the number of the positioning columns is equivalent to that of the long sliding holes 32, and each positioning column 22 is respectively used for matching with the corresponding long sliding hole 32, so that the positioning columns 22 relatively slide in the long sliding holes 32 along the extending direction thereof. With this arrangement, the sliding connection plate 31 and the telescopic pressing plate 3 can slide in the width direction and adjust the position on the surface of the mounting rail 2 by the relative sliding in the transverse direction between each long sliding hole 32 and the positioning column 22. Meanwhile, the positioning column 22 abuts against the hole wall of the long slide hole 32, so that the transverse sliding stroke of the sliding connection plate 31 and the telescopic pressing plate 3 on the installation guide rail 2 can be limited.

In addition, considering that not only the width dimension of a part of the servers a is different from the standard dimension, but also the height dimension of the part of the servers a is different from the standard dimension, for example, when the height dimension of the servers a is large, the telescopic pressing plate 3 may be difficult to press the side wall of the servers a completely, resulting in insufficient clamping stability of the servers a, for which, the extension substrate 6 and the extension pressing plate 7 are added in the present embodiment.

As shown in fig. 7 and 8, fig. 7 is a schematic view of an installation structure of the extension substrate 6 and the extension pressing plate 7, and fig. 8 is a schematic view of a structure in which the extension pressing plate 7 presses the side wall of the server a.

The extension base plate 6 is vertically connected to the top of the installation rail 2, extends along the length direction of the installation rail 2, and has a length equal to the length of the installation rail 2 and a certain height, such as the height equal to the height of the vertical plate 21 of the installation rail 2, and is mainly used for being connected with the extension base plate 6 as a whole so as to increase the height of the extension base plate 6.

Similarly, extend clamp plate 7 along the top of vertical connection at flexible clamp plate 3 to extend along the length direction of flexible clamp plate 3, its length can be equivalent with the length of flexible clamp plate 3, and self has a take the altitude, for example can be equivalent with the height of flexible clamp plate 3, mainly used is connected as an organic wholely with flexible clamp plate 3, so that increase the height of flexible clamp plate 3, and then increase the cover of flexible clamp plate 3 to server a lateral wall and compress tightly the area, thereby be adapted to highly great server a more.

In addition, although the elastic deformation of the elastic members 4 can normally drive the telescopic pressing plate 3 and the extension pressing plate 7 to simultaneously and synchronously move in the transverse direction, the auxiliary elastic members 8 are additionally arranged in the embodiment in consideration of the fact that the elastic members 4 are not directly connected with the extension pressing plate 7. Specifically, each supplementary elastic component 8 all is connected between extension base plate 6 and extension clamp plate 7, and its structure is similar with each elastic component 4 with the distribution situation to elastic deformation direction also is the width direction of installation guide rail 2, so sets up, and when installing different width dimension's server a, each elastic component 4 can carry out synchronous elastic deformation with each supplementary elastic component 8, and drive respectively flexible clamp plate 3 and extend clamp plate 7 and carry out synchronous lateral sliding.

As shown in fig. 9, fig. 9 is a schematic view of a connection structure of the extension substrate 6 and the mounting rail 2.

In order to facilitate the connection between the extension base plate 6 and the upright plate 21 of the mounting rail 2, an outer connecting plate 23 is added in this embodiment. Specifically, the external connection plate 23 is disposed at the top of the vertical plate 21, and is generally in a bent plate shape, and the bottom of the extension base plate 6 is also in a bent plate shape, and the external connection plate and the extension base plate are tightly attached to each other and detachably connected by fasteners such as bolts, screws, rivets, and the like, so as to be detached and installed according to the actual size of the server a.

As shown in fig. 10, fig. 10 is a schematic view of a connection structure of the extension pressing plate 7 and the extension pressing plate 3.

Similarly, in order to facilitate the connection between the extension pressing plate 7 and the extension pressing plate 3, an inner connection plate 33 is added in the present embodiment. The inner connection plate 33 is disposed at the top of the retractable platen 3, and is generally in a bent plate shape, and the bottom of the extendable platen 7 is also in a bent plate shape, and the inner connection plate and the extendable platen are tightly attached to each other and detachably connected by fasteners such as bolts, screws, rivets, and the like, so as to be disassembled and assembled according to the actual size of the server a.

In addition, considering that only the inner side area of the mounting rail 2 is used for supporting the bottom of the server a because part of the area of the mounting rail 2 is occupied by the telescopic pressing plate 3 and the extension pressing plate 7, the outer side area of the mounting rail 2 is empty and generally in a hollow state, so that when the fan operates to dissipate heat, part of the heat dissipation airflow will flow from the outer side area of the mounting rail 2 and not pass through the server a, which results in the reduction of the heat dissipation performance of the server a. For this, the flow guide mechanism 9 is added in this embodiment.

The flow guide mechanism 9 is mainly used for guiding the intake air flow which gushes from the air inlet so as to guide the heat dissipation air flow which blows to the outer side area of the installation guide rail 2 to the inner side area of the installation guide rail, and therefore the heat dissipation performance of the server a is improved.

As shown in fig. 13, fig. 13 is a schematic structural diagram of the diversion base 91.

Specifically, the air guide mechanism 9 is a split structure, and mainly includes an air guide base 91 and an air guide cover 92. Wherein, water conservancy diversion base 91 mainly is the rectangular frame structure, specifically sets up the front end position of the medial surface of riser 21 of installation guide rail 2, and the joint is realized through the cooperation between the protruding positioning groove on the locating protrusion of setting on the water conservancy diversion base 91 outside and the medial surface of riser 21 to the accessible simultaneously, still can strengthen connection stability through the joint cooperation that sets up between the trip of water conservancy diversion base 91 bottom surface and the draw-in hole on installation guide rail 2 surface.

As shown in fig. 14, fig. 14 is a detailed structural diagram of the air guide sleeve 92.

The rear end face of the air guide sleeve 92 is tightly attached to and abutted against the front end face of the air guide base 91, meanwhile, the clamping hook arranged on the rear end face of the air guide sleeve 92 and the clamping groove at the front end of the telescopic pressing plate 3 form clamping fit, and the connection stability can be enhanced through the clamping fit of the positioning protrusion arranged on the rear end face of the air guide sleeve 92 and the positioning groove on the inner side face of the front end of the telescopic pressing plate 3.

Similarly, the air guide sleeve 92 is also arranged at the front end of the extension pressing plate 7, and the specific connection relationship of the air guide sleeve 92 and the extension pressing plate 3 is the same as that of the air guide sleeve 92.

As shown in fig. 15, fig. 15 is a schematic flow direction diagram of the intake airflow at the diversion mechanism 9.

In a preferred embodiment with respect to the air guide sleeve 92, the front end surface of the air guide sleeve 92 is embodied as a bevel or wedge surface facing the inner side surface area of the mounting rail 2 or the mounting area of the server a in order to facilitate the air guide effect. Generally, the inclined angle of the inclined surface or the wedge-shaped surface can be 30-45 °.
