Problems solved by technology

[0002] Most of the existing service robots or logistics robots use rotating shafts or ordinary hinges for the upper rotating mechanism of the movable maintenance door. Due to manufacturing and assembly errors, the gaps between the matching parts of the plastic movable parts are large, and there are obvious steps on the outer surfaces of different parts. Therefore, The appearance of the two matching parts is not detailed enough

Abstract

The invention discloses a limiting device for a plastic housing, and belongs to the field of housing assembly. The limiting device comprises a movable door housing, wherein one end of the movable doorhousing is provided with a plurality of first installation grooves and a plurality of bosses; a movable door top frame, one end of which is provided with a plurality of second installation grooves and a plurality of grooves, wherein the grooves are matched with the bosses, and the movable door top frame can be rotatingly arranged at the upper end of the movable door housing around the length direction of the second installation grooves; and a plurality of link hinges, each of which comprises a first rotating installation block, a second rotating installation block, and a rotating part, wherein two ends of each rotating part are respectively provided with a first installation block and a second installation block, each first installation block is installed in one first installation groove,and each second installation block is installed in one second installation groove. The limiting device is simple and reliable, is low in manufacturing cost, and can guarantee that the external surfaces of two housings are located on the same vertical plane.

Description

technical field [0001] The invention relates to the technical field of shell assembly, in particular to a limiting device for a plastic shell. Background technique [0002] Most of the existing service robots or logistics robots use rotating shafts or ordinary hinges for the upper rotating mechanism of the movable maintenance door. Due to manufacturing and assembly errors, the gaps between the matching parts of the plastic movable parts are large, and there are obvious steps on the outer surfaces of different parts. Therefore, The appearance of the two matching parts is not detailed enough. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the aim is to provide a limiting device for the plastic shell, which realizes automatic alignment during the process of closing the dodge door through the linkage hinge and the structure of the boss groove on the plastic part, and keeps The outer sides of the housings are aligned to av...
