Description

A kind of fabricated cabinet frame structure

Technical field:

The present invention relates to a kind of frame structure of rack, particularly relate to a kind of frame structure of fabricated rack.

Background technique:

The rectangular cabinet of using Electric Appliance Cabinet, switch cubicle, packing cabinet or the like in the industrial and agricultural production process is very general, its structure generally all adopts welding, clinching method, once moulding, permanent fixation, this traditional rack can have enough intensity, time-consuming the taking a lot of work but processing is got up, for overcome weldering, a distortion difficult problem of bringing is processed in riveting, will heat-treating of having overcomes internal stress, with the installation of smooth, the attractive in appearance and plug connector elements that guarantees rack.Because of bin is an integrity, in case rack is impaired, what that was I guess very little a bit damages, and also wants integral body to scrap, and causes no small waste.It also is very important defective that integrally-built rack makes the transportation of sky cabinet cause the transport power waste.In recent years, people are doing many effort and trial aspect the rack processing, many corrective measures are proposed, to overcome the defective of tratitional technology, be called " metal framework structure that improved type angle fastening piece is housed that aims at the electrical equipment cabinet design " U. S. Patent [patent No.: us6299268B1] as the name that October 9 calendar year 2001, approval was authorized, the crossbeam and the interlock between the column of assembling type framework are wherein finished by custom-designed angle connector, this angle connector is that a shape is comparatively complicated, processing technology is complicated, comprise 20 ° to 40 ° the acute angle scope before close the metal ceramic of trapezoidal sectional shape after opening, for whole employing sheet metal gold copper-base alloys, simple in structure, installation and processing is convenient, and sufficient intensity is arranged again, the assembling type rack of rigidity does not see that as yet report is arranged.

Summary of the invention:

Common rack all is made up of frame structure and panel, to increase the rigidity and the intensity of rack, technological scheme of the present invention is such: a kind of fabricated cabinet framework is by up and down two bases 4 and four corner posts 1, is formed by connecting by tight piece 3 in eight groups of angle contiguous blocks 2 and the angle.Wherein: (1) corner post 1 adopts the punching press of metal cold-reduced sheet, the bending of 1-2.5 millimeter to form, its sectional shape is the hexagon rhombus (as Fig. 2) of the symmetry of openings at one side, angle is respectively 90 °, 135 °, 135 °, 90 ° in each limit, turn up in the both sides of opening, become 90 ° of angles respectively with adjacent side, the length of this corner post 1 is changeable, with bin, rack actual height and scale; (2) angle contiguous block 2 adopts the metal cold-reduced sheet of 2-4.5 millimeters thick to form rectangular shaped through punching press, bending.Sheet metal member (as Fig. 2), the vertical surface of the sheet metal member that this is rectangular-shaped is divided into left vertical surface 24, middle vertical surface 25, right vertical surface 26, all vertical bottom face 27, left side vertical surface 24 and right vertical surface 26 disconnect with bottom surface 27 and respectively with 135 ° of angles of middle vertical surface 25 invaginations, make left vertical surface 24 and right vertical surface 26 constitute disjoint 90 ° of positions, middle vertical surface 25 and the vertical bending of bottom surface 27 one, left side vertical surface 24 intersects vertically with the base and the bottom surface 27 of right vertical surface 26, spot welding is fixed, bottom surface 27 afterbodys away from vertical surface also have upwards, outwards bending twice (as Fig. 8), to match with base 4 shapes, respectively there is one through hole 22 is installed on the top of left vertical surface 24 and right vertical surface 25, be used for and base 4 fixing using, on the both sides that through hole 22 is installed, two protruding wedges 21 are respectively arranged, the location is used when being used for base 4 installations, the centre of vertical surface 25 has and clamps in through hole 23 and the angle tightly that piece 3 cooperates fixed angles column 1 usefulness, two mounting holes 22 on the bottom surface 27 are used for and base 4 fixing using, and four microscler protruding wedges are arranged under the base, two right angles of bottom surface 27, the location is used when being used for base 4 installations; (3) tight piece 3 is watt shape sheet metal members (as Fig. 7) that become three of two foldings by the cold rolled metal plate of 2-4.5 millimeters thick through punching press, Bending Processing in the angle, the left and right two folding faces 31 of its symmetry and 34 and the angle of midplane 32 be 135 °, the central authorities of midplane 32 have a clamping through hole 33 to cooperate with angle contiguous block 2 with fixed angles column 1 usefulness, and the size of tight piece 3 is just in time to insert the rhombus inner chamber of corner post 1 in the angle; (4) base 4 by the cold rolled metal plate of 1-2.5 millimeters thick through punching press, Bending Processing forms the rectangle frame integral body of sufficient intensity, the cross section of this rectangle frame is as the rectangular tube (as Fig. 2) of an opening, three interior angles in the pipe in four interior angles are 90 ° of right angles, on one jiao of opening, two flange 44 and 48 all turn up and 47 one-tenth 90 ° of right angles of adjacent upper overturning adjacent side 45 and following flange adjacent side down, each three circular hole arranged side by side (as Fig. 4) of the two ends of upper overturning 44, be respectively positioning hole 41 and mounting hole 42, bottom surface 46 corner locations of base 4 respectively have two mounting holes 42 and four location elongated slots 43.

Implement when of the present invention as long as above-mentioned member is assembled as follows connection:

(1) base 4 is aimed at positioning hole 41 with four angle contiguous blocks 2 by protruding wedge 21; Four microscler protruding wedges are aimed at corresponding location elongated slot 43 on the base of angle contiguous block 2, and every frame corners is location, totally eight places, and in mounting hole 42 and 22 place's bolton.

(2) with the vertical corner location that inserts base 4 of four corner posts 1, again will be at the angle of watt shape in watt shape of tight piece 3 insert the inner chamber of corner post 1 dorsad behind the center of base 4, connect by bolt and clamp through hole 23 and clamping through hole 33, corner post 1 is fixedly clamped.

Repeat above-mentioned installation steps upper base 4 is installed, promptly successfully form a fabricated cabinet framework.

Tight piece 3 and base 4 adopt the cold rolled metal plate to make in corner post 1 of the present invention, angle contiguous block 2, the angle, also can partly or entirely make with engineering plastics, nylon, casting alloy.

Good effect of the present invention is the cabinet framework that all adopts metal sheet metal member to be assembled into, draw materials easily, processing, interchangeability easy for installation, component is good, if any damaged condition, as long as the removable parts component do not influence the use of whole framework, the invention of assembling type cabinet framework makes the rack processing and transports the simplification that all becomes, can save production site and empty cabinet freight greatly, can zero member transportation in bulk, assembled in situ is used.
