Embodiment
In order to make the object, technical solutions and advantages of the present invention clearer, the present invention is made below in conjunction with attached drawing into
One step it is described in detail, it is clear that the described embodiment only a part of embodiment of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
All other embodiment, belongs to the scope of protection of the invention.
Fig. 1 a illustrate a kind of structure diagram front view of cabinet provided in an embodiment of the present invention, Fig. 1 b examples
Property shows a kind of structure diagram stereogram of cabinet provided in an embodiment of the present invention, as illustrated in figs. 1A and ib, including cabinet
Body 101, the stent 102 being arranged inside the cabinet, multiple location structures 103, the server being arranged on the stent
104.Wherein, each location structure is obliquely installed on stent, and server is positioned on location structure in an inclined manner, server
Can be along axis L into and out cabinet.
In the present invention, by setting stent and location structure inside cabinet body so that server being capable of slant setting
In on location structure, so as to mitigate the lifting force for taking out server, the efficiency of server maintenance is effectively improved, simplifies service
The operating procedure that device is safeguarded, realizes the purpose that server can be relatively easily taken out not by auxiliary lifting equipment.
In the embodiment of the present invention, the connection mode of location structure and stent has a variety of, the first connection mode is positioning knot
Structure can be directly welded on stent；Second of connection mode is that location structure can also be fixedly connected by bolt with stent,
The present invention is not specifically limited.Using second of connection mode, easy to the dismounting of location structure, facilitate subsequent maintenance, replace.Class
As, the connection mode of stent and cabinet can be welding, or be bolted, the present invention is not specifically limited.
Based on above-mentioned cabinet, in the embodiment of the present invention, stent can be the structure that plate connects into, or beam connection
Structure.The present invention provides a kind of structure of beam connection, and Fig. 2 illustrates a kind of knot of stent provided in an embodiment of the present invention
Structure schematic diagram, as shown in Fig. 2, the stent includes upper beam 201, bottom end rail 202, pillar 203., can using this structure
Raw material is saved, it is cost-effective.
In the present invention, it is positioned over for the ease of stent inside cabinet, the length of stent needs the length less than cabinet.
Further, in order to facilitate the placement of server, the quantity of upper beam is two；But the present invention is to the number of bottom end rail
Amount and the quantity of column are not specifically limited, and one kind is possible to be achieved in that, the quantity of bottom end rail is two, the quantity of column
For four, in this way, material can be farthest saved on the premise of stable structure, reduce cost.
In the embodiment of the present invention, cabinet can also include the multiple metallic channels being arranged on the side plate of cabinet, the conducting wire
Groove is used to distinguish the cables of multiple servers, so that the cable of each server is from metallic channel corresponding with each server
In be pierced by.Specifically, metallic channel can be arranged on the side plate of cabinet side；Alternatively, metallic channel can be arranged on cabinet both sides
Side plate on, do not limit specifically.
In the embodiment of the present invention, the placement for location structure, multiple location structures could be provided as different inclinations angle
Degree, as long as ensureing that server can be with slant setting on location structure.Optionally, in the embodiment of the present invention, each location structure
It is arranged at identical angle of inclination on stent, can so reduces the influence when pulling server between detent mechanism,
Be conducive to the unified production installation of detent mechanism.
The present invention is not specifically limited the size at the angle of inclination of location structure, and one kind is possible to be achieved in that, institute
Angle of inclination is stated in the range of 30 ° to 45 °, reduces the pulling force for pulling out and being needed during server as far as possible.
Further, in the present invention, location structure is uniformly distributed in inside cabinet, and, between any two location structure
Distance can be slightly larger than the thickness of server, so can more placement server as far as possible.
In the embodiment of the present invention, in the case where cabinet receives external force effect so as to produce vibrations, easily so that being placed on
Server on location structure also shakes, so that the problem of causing server to damage.For this problem, there are a variety of solutions
Mode, a kind of possible implementation are to set buffer structure in the positioning plate both sides of location structure, so as to mitigate cabinet vibrations
Influence to server.In the embodiment of the present invention, buffer structure can be made of materials such as sponge, foam, inflatable cushions, specifically not
Limit.
Alternatively possible implementation is to set buckle structure on the positioning plate of location structure, when server is placed
When on location structure, buckle structure pins server so that server is fixed on location structure；When need remove server
When, buckle structure no longer pins server so that server can be removed.In this way, outer masterpiece is received in cabinet
In the case of so as to produce vibrations, server is fixed on location structure by buckle structure, can effectively avoid server
Produce the problem of vibrations cause to be damaged.
In the embodiment of the present invention, for the ease of the placement of server, cabinet further includes the stop part for being arranged at bottom of cabinet bulk,
Stop part is more than the thickness of server with location structure distance in the horizontal direction.Optionally, each location structure corresponds to one
Stop part, has so further ensured server tilted-putted mode on location structure.The specific implementation of stop part
Can be various, such as a protruding block or a raised item or a groove.In practical operation, it can be placed according to server
Stressing conditions on detent mechanism determine the need for setting stop part.
In the embodiment of the present invention, location structure can be guide rail structure, or caterpillar belt structure, can also be hardened
Structure, the present invention are not specifically limited.Different structures will be hereafter specifically described.
Structure one：Guide rail structure
