the second hinge columns 92.2 of the two limiting frames 90 are respectively contacted with the side wall of the upper box body 2 and the side wall of the lower box body 1.
The working principle of the technical scheme is as follows: this detection device is when using, because the detection device that sets up on last box inner wall is too much and lead to the weight between box, the lower box unbalanced, its one side with lower box articulated when last box is opened can the perk inevitable, just as figure 12 can have certain contained angle with the horizontal plane, in case the perk angle is too big can lead to box, two base angles that lower box is adjacent extrude each other and make the two easy damaged, and the perk angle still can lead to the unable normal use of detection device moreover. Adopt common articulated shaft to articulate upper box body, lower box body together obviously not applicable, the emergence of above phenomenon can't be avoided, consequently adopt the semi-limited hinge assembly that this embodiment provided to realize the articulated of upper box body, lower box body. The concrete structure is as follows: the connecting webs 60 shown in fig. 11 are arranged on the sides of the upper box body and the lower box body which need to be hinged, namely a first connecting web 61 and a second connecting web 62, the two webs are hinged through a rotating dry shaft 70, and a first fixed fulcrum 81 and a second fixed fulcrum 82 are arranged on the two sides of the rotating dry shaft 70. A plurality of semi-constrained hinge assemblies are provided between the rotary stem 70, the first fixed fulcrum 81 and the second fixed fulcrum 82. The semi-limited hinge assembly comprises two symmetrically arranged limiting frames 90, namely a first limiting frame 90.1 and a second limiting frame 90.2, wherein the two limiting frames 90 are respectively hinged on a first fixed fulcrum 81 and a second fixed fulcrum 82, and the rotating dry shaft 70 is clamped between the two limiting frames by a U-shaped clamp beam 100 and a load bearing flexible belt 110.
When the lower box body 1 and the upper box body 2 are in an open state, on one hand, the bearing flexible belt 110 limits the rotation angle of the lower box body 1 and the upper box body 2 under the limiting action of the rotation dry shaft 70 to avoid overlarge tilting angle of the lower box body 1 and the upper box body 2, namely, when the lower box body 1 and the upper box body 2 are in an open state, the first limiting frame 90.1 tends to rotate anticlockwise, the second limiting frame 90.2 tends to rotate clockwise, and the bearing flexible belt 110 limits the rotation tendency of the lower box body 1 and the upper box body 2, so that the bottom angles of the lower box body 1 and the upper box body 2 are prevented from being extruded. On the other hand, the second hinge columns 92.2 of the two limiting frames 90 respectively contact with the side walls of the upper box body 2 and the lower box body 1 to limit the rotation tendency of the upper box body and the lower box body, and under the limitation of double limitation, the lower box body 1 and the upper box body 2 can be prevented from being damaged due to unbalanced gravity distribution.
The beneficial effects of the above technical scheme are that: the semi-limited hinge assembly formed by the double limiting frames is adopted to replace a common hinge structure to hinge the upper box body and the lower box body into a whole in a semi-limited mode, and under the fixed angle arrangement limiting action of the two limiting frames, the upper box body and the lower box body can only be hinged and rotated within a preset rotating range, so that the upper box body and the lower box body are semi-limited under the hinge structure.
