The utility model is characterized in that the cross section of the upright post is a polygon with an opening; the ratio of the longitudinal and transverse edges of the polygon is larger than two; connecting supporting rods which are in embedded match with openings of the upright post respectively vertically extend from four corners of the top and the bottom frames; horizontal reinforced edges are formed on the front and the back edges of the top and the bottom frames; both ends of the horizontal reinforced edges are connected with corresponding connecting supporting rods. The polygon of the cross section of the hollow upright post is an oblong with an opening or a polygon with multiple bend. The utility model has the advantages of easy manufacture, convenient assembly, high precision, and large strength intensity and rigidity of the rack frame.

Description

The cabinet framework that is used for telecommunications

The utility model relates to the rack that is used for telecommunications, relates to the cabinet framework that telecommunications is used specifically.

Disclose a kind of frame-type frame in patent documentation DE 3344598, this frame-type frame is used widely at present in the world.Its structure as shown in Figure 5, the cross section of forming the pillar of framework is square or the less polygon of length limit ratio, trident angle connector is that die casting forms.Assembling such frame needs Special Equipment, and the assembly precision requirement is high, so production cost is higher, need reach production in enormous quantities, could obtain certain economic benefits.In addition, in actual use, make the rigidity of pillar less, when framework will produce bigger distortion when short transverse is stressed, thereby influence the integral rigidity of framework owing to the pillar sectional area is less; Like this, the requirement of strength of diagonal angle connector is very high, has improved difficulty of processing and production cost equally.

In view of the above problems, the purpose of this utility model provides that a kind of its member manufacturing is simple, bulk strength and rigidity are big and assemble the cabinet framework that easy telecommunications is used.

For achieving the above object, the cabinet framework that is used for telecommunications of the present utility model is made up of column, top frame and underframe, is characterized in: the cross section of described column for the ratio on limit in length and breadth greater than 2 polygon with opening emptying aperture; Described top frame and underframe four jiaos respectively vertically extending the pole that is connected with the emptying aperture scarf of described column is arranged; The front and rear side of described top frame and underframe is formed be connected the horizontal stiffened edge that pole be connected corresponding with each.

The cross section polygon of described hollow column is to have the rectangle of opening or have the repeatedly polygon of bending.

The advantage of technique scheme of the present utility model is as described below:

Because the bending strength of the horizontal direction of framework relies on the stiffened edge of top frame and underframe and is connected pole and rectangle that column is formed guarantees, its longitudinal direction bending strength relies on the rectangle assurance of vertical limit of column and top, underframe composition; And the bigger big bending resistance that aspect ratio had of column can provide framework stronger anti-twisting property, and therefore, cabinet framework of the present utility model has higher bulk strength and rigidity; Member top frame, underframe and the column of framework can be made by simple panel beating bending technology, handling ease, thereby production cost is low; Owing to column in length and breadth the ratio on limit increased greatly cross section, the bonding strength and the precision that connect pole and the scarf of column obtain raising; Owing to connect pole is integrally formed on top, underframe, and the angle precision of framework can guarantee by top, underframe, and therefore the calibration of angle precision when having avoided assembling is assembled easy and guaranteed precision.

Further specifically describe preferred embodiment of the present utility model below with reference to accompanying drawings, so that clearlyer understand the purpose of this utility model, characteristics and advantage.

Fig. 2 A and Fig. 2 B are the cross sectional representation of column of the present utility model;

Fig. 3 is the exploded perspective view of Fig. 1 preferred embodiment;

Fig. 4 is the assembling schematic perspective view of Fig. 1 embodiment;

Fig. 5 is the schematic perspective view of at present general cabinet framework.

As shown in figs. 1 and 3, the cabinet framework that is used for telecommunications of the present utility model is made up of column 31,32,33,34 and top frame 1 and underframe 2, the cross section of column 31 to 34 for the ratio on limit in length and breadth greater than 2 polygon with opening emptying aperture, for example Fig. 2 a and 2b are depicted as the rectangle with opening or have repeatedly the polygon of bending, and its limit that vertically promptly illustrates the Y direction is laterally promptly to illustrate more than the twice on limit of directions X; Four jiaos of described top frame 1 and underframe 2 are extended with respectively and are connected pole 41,42,43 and 44, and each connects pole has and the rectangle or the polygonal shape of cross section of bending repeatedly, they respectively with the emptying aperture scarf of described column 31 to 34; The front and rear side of top frame 1 and underframe 2 has the horizontal stiffened edge 51,52 of horizontal expansion.The two ends of stiffened edge 51 respectively be connected pole 41,43 connection, and the two ends of stiffened edge 52 respectively with is connected pole 42,44 connections.

Fig. 4 illustrates the assembling process of cabinet framework of the present utility model, shown in arrow among the figure, with top frame 1 and underframe 2 be connected pole 41,42,43,44 respectively scarf advance in the emptying aperture of corresponding hollow column 31,32,33,34, can form cabinet framework, assemble very easy reliably.
