Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In the present disclosure, unless otherwise specified, the terms of orientation such as "upper" and "lower" are generally defined based on the orientation or positional relationship shown in the drawings, and specifically refer to the direction of the drawing shown in fig. 1 in combination with the positional relationship of the corresponding parts in other drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.
As shown in fig. 1 and 2, the utility model relates to an opening and closing mechanism for lamp installation, lamps and lanterns include lamp stand 5 and face lid 3, lamp stand 5 installs in the wall crown, bulb 4 is installed in the suspension below lamp stand 5, face lid 3 installs in the suspension below bulb 4 through opening and closing mechanism, opening and closing mechanism includes suspension arm 2 and sleeve 1, lamp stand 5 forms into the cylinder structure, sleeve 1 is located on lamp stand 5, the suspension arm 2 upper end that can rotate along lamp stand 5 is articulated with lamp stand 5 bottom surface, the suspension arm 2 upper segment is along the vertical setting of lamp stand 5 outer wall extending direction, the suspension arm 2 middle section leans out and sets up, the suspension arm 2 lower segment is inwards horizontally set up, the length of sleeve 1 is greater than the length of suspension arm 2 upper segment and is less than the length of lamp stand 5;
three suspension arm 2 are installed to 5 below of lamp stand, and face lid 3 is located the inboard of three suspension arm 2, and face lid 3 arranges the upside of suspension arm 2 hypomere in, and when sleeve 1 moved down to suspension arm 2 upper segment, sleeve 1 overlaps in suspension arm 2 and lamp stand 5 simultaneously, and three 2 hypomere of suspension arm are closed a concerted effort and are held face lid 3, and when sleeve 1 moved up to lamp stand 5, sleeve 1 only overlaps in lamp stand 5, and suspension arm 2 overturns around lamp stand 5 to the outside, and face lid 3 can be taken.
