Embodiment 1

[0018] See Figure 1 to Figure 8 , this embodiment includes two planar frames 10 connected by two type I rods E and two type II rods F through first screws 4, and four uprights 20 are connected between the two planar frames 10 through second screws 5 connection, column 20 adopts type I rod E.

[0019] The first surface E-1 of the Type I rod is provided with a straight groove L-1 through both ends, and the surface away from the straight groove L-1 and perpendicular to the first surface E-1 of the Type I rod is the second surface E of the Type I rod -2. A flange K is provided at the junction of the first surface E-1 of the type I rod and the second surface E-2 of the type I rod.

[0020] The end face F-3 of the type II rod is provided with an arc groove L-2, and the two perpendicular surfaces opposite to the arc groove L-2 are the first face F-1 of the type II rod and the second face of the type II rod. Two faces F-2, the junction of the first face F-1 of type II rod and the s...

Abstract

The invention discloses a positive-pressure explosion-proof box three-dimensional frame. The three-dimensional frame comprises two plane frames and four stand columns, and each plane frame is formed by connecting two I-shaped rods and two II-shaped rods; straight grooves are formed in the first faces of the I-shaped rods, and arc grooves are formed in the end faces of the II-shaped rods; the second faces of the two I-shaped rods of each plane frame and the second faces of the two II-shaped rods of each plane frame are spliced to form an annular top face or an annular bottom face; the first faces of two II-shaped rods, on the same sides, of the two plane frames are spliced with the second faces of two I-shaped rods serving as the stand columns to form an annular front face or an annular rear face; the first face of one I-shaped rod, on the same sides, of the two plane frames are spliced with the first faces of two I-shaped rods serving as the stand columns and the end faces of each twoII-shaped rods on the two plane frames to form annular side faces; the straight grooves in the I-shaped rods and the arc grooves in the end faces of the II-shaped rods define sealing grooves; and a plurality of magnetic block holes are formed in one annular side face. According to the three-dimensional frame, by adopting a structure that the two shapes of rods are spliced and connected through screws, the bearing capacity is high, the sealing effect is good, and machining and mounting are easy.

Description

technical field [0001] The invention relates to a three-dimensional frame of an explosion-proof box. Background technique [0002] In hazardous places containing explosive gases, vapor mixtures or combustible dust, it is necessary to record some key data on the site in paper form through a printer, and at the same time, print the content of data and instructions transmitted on site through remote communication. Since the print head of the printer will generate instantaneous high temperature and high energy, the exposed printer may ignite flammable gas and dust when working in a hazardous location. Conventional explosion-proof equipment must be placed in an explosion-proof box to isolate it from external hazardous places, so consider placing the printer in an explosion-proof box. The utility model of Chinese patent application No. 201220337153.1 introduces a box body of a motorcycle packing box, which is composed of an upper frame, a lower frame and several upright columns a...
