a right-angled triangular connecting piece is fixedly connected to the front part and the rear part of the joint of the upright column and the left side frame and the right side frame respectively, a straight vertical bending piece is arranged on each of two right-angled sides of the right-angled triangular connecting piece, and the two bending pieces are connected with the upright column and the side frame respectively;
the surface of the right-angled triangular connecting piece is provided with a connecting hole for connecting a side door;
a plurality of assembling holes for fixing the device mounting plate are formed in the upright post;
the front and rear portions of the left and right frames are symmetrically provided with L-shaped connecting pieces used for installing side doors, and connecting holes used for fixing the side doors are formed in the L-shaped connecting pieces.
In the cabinet frame, the left frame and the right frame can be groove-shaped structures, and the notches of the left frame and the right frame face the inner side; and notches for the upright posts to be inserted are formed in the inner sides of the connecting positions of the left and right frames and the upright posts, and the upper end and the lower end of each upright post are respectively inserted into the corresponding notches.
In the cabinet frame, a reinforcing plate which enables the notches to form a closed insertion opening can be arranged on the inner side of each notch. At this time, a reinforcing plate connecting hole for connecting with a column may be provided on the reinforcing plate, and column connecting holes corresponding to the reinforcing plate connecting hole may be provided at upper and lower ends of the column, respectively; and then, the reinforcing plate and the upright post are fixedly connected through screws inserted into the reinforcing plate connecting holes and the upright post connecting holes.
In the rack provided by the invention, only two upright columns form the rack, so that the types of materials and the number of parts for manufacturing the rack can be reduced, the dead weight of the rack can be reduced, the manufacturing cost and the production management cost of products can be reduced, and the upright columns are arranged between the left frame and the right frame, so that the operation space of the cabinet is increased, and the components arranged in the cabinet are convenient to install and maintain.

Detailed Description
Referring to fig. 3, 4 and 5, it can be seen that the frame is provided with only two vertical posts 2 connected to the left and right frames of the upper and lower frames 1 and 3, the left and right frames are in a groove shape, the upper and lower ends of the vertical posts 2 are inserted into the notches and then fixedly connected by welding.
For the frame intensity when only adopting two stand 2 structures, the corner rigid coupling that constitutes has right triangle-shaped connecting piece 5 on stand 2 and left and right frame, and two right-angle sides of this right triangle-shaped connecting piece respectively are equipped with the perpendicular piece of buckling all the time, and these two pieces of buckling are connected with stand and frame respectively, make the connection of stand 2 and frame more firm. The right-angled triangle connecting piece 5 is provided with a connecting hole for connecting a side door.
As shown in fig. 4, L-shaped connecting pieces 6 which are in L-shaped structures and are convenient for connecting and fixing the side doors are symmetrically arranged on the left and right frames; as shown in fig. 5, a connection hole for connecting to the side door is provided in the L-shaped link 6.
When assembling the cabinet by using the rack, each side door in the cabinet can be connected into a whole by the upper and lower enclosing frames, the upright posts, the L-shaped connecting pieces and the right-angled triangular connecting pieces, so that the overall structural strength of the cabinet is enhanced. In the left and right direction, the back door can be fixed on two side doors, so that the side doors and the back door are connected into a whole. As can be seen from fig. 3 and 4, a plurality of mounting holes are further formed in the two columns 2, and the mounting holes can be used for fixing the device mounting plate arranged in the cabinet, and the mounting plate and the rear door can also enhance the strength of the whole cabinet in the left-right direction.
A second preferred embodiment of the present invention is shown in fig. 6 and 7, in which the upright 2 and the frame in the first embodiment are connected by welding, and the present invention further provides a frame connected by splicing, on the basis of the welded frame, a reinforcing plate 7 forming a closed insertion opening with the notch is fixedly connected to the inner sides of the left and right frames, a reinforcing plate connecting hole is formed in the reinforcing plate 7, and an upright connecting hole corresponding to the reinforcing plate connecting hole is formed in the end portion of the upright 2.
