Grid disc supporting assembly and environmental test box

Abstract

The invention belongs to the technical field of environmental tests, and discloses a grid disc supporting assembly and an environmental test box, the grid disc supporting assembly comprises two groups of supports and a slide rail, and the two groups of supports are respectively arranged on two opposite inner walls of the environmental test box; a plurality of variable-diameter mounting holes are formed in the support in the vertical direction, and the variable-diameter mounting holes comprise first holes and second holes which communicate with each other; the at least two sliding rails are connected to the two sets of supports respectively, variable-diameter installation heads are arranged on the sliding rails, each variable-diameter installation head comprises an installation cap and an installation neck, the variable-diameter installation heads and the variable-diameter installation holes are selectively installed in a matched mode so that the installation heights of the sliding rails can be adjusted, disassembly and assembly are convenient and fast, and the two ends of the grid disc are supported on the top end faces of the two sliding rails. According to the invention, the grid disc is in surface contact support with the slide rail, so that the support stability of the grid disc is improved; clamping grooves or clamping protrusions do not need to be machined on the grid disc, the strength of the grid disc is ensured, and deformation is avoided; and the height position of the grid disc is realized through switching of the slide rails on the bracket, so that the test safety and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of environmental testing, in particular to a grid disc support assembly and an environmental testing chamber. Background technique [0002] The environmental test box is a box used for environmental simulation testing of electronic, mechanical and other components or finished products. The grid plate is used as a load-bearing mechanism for placing test samples. It is placed on the grid plate bracket in the box, and the grid plate bracket is fixed on On the side of the inner wall of the test chamber, multiple slots are set on the grid plate bracket along the height direction. When testing samples of different heights, the grid plate can be taken and placed in the slots of different heights on the grid plate bracket to adapt to samples of different heights. test. [0003] When the weight of the test sample is heavy, the connection method of the card slot is easy to deform and loose due to the point support st...
