Be respectively equipped with upper and lower two bearings in the inner side of every sheet flanged plate, bearing is arranged in the vallecular cavity of grooved guide rail, and the inner ring of bearing and flanged plate utilize rivet to be connected as a single entity, and rolls with grooved guide rail and coordinate in the outer ring of bearing;
Erection support is respectively equipped with in the front of every root vertical guide, each erection support is rotatably mounted with the first drive link, the second drive link, the inner side of the first drive link is provided with the first collision block, and the inner side of the second drive link is provided with the second collision block, and the first collision block is positioned at below the second collision block; The end of every root first drive link is hinged with first connecting rod, and the end of every root first connecting rod is hinged with the flanged plate of valve page respective side above; The end of every root second drive link is hinged with second connecting rod, and the end of every root second connecting rod is hinged with the flanged plate of valve page respective side below; Be provided with torsion spring between erection support and the second drive link of respective side, the force direction of torsion spring to the second drive link makes it upwards rotate.
In the utility model, so-called " notch toward the outer side ", for the vertical guide being positioned at the left side, refers to that notch is towards left side, for being positioned at the vertical guide on the right, refers to that notch is towards right side.So-called " inner side of flanged plate ", for the flanged plate being positioned at the left side, refers to the right side of flanged plate, for being positioned at the flanged plate on the right, refers to the left side of flanged plate.So-called " inner side of drive link ", for the drive link being positioned at the left side, refers to the right side of drive link, for being positioned at the drive link on the right, refers to the left side of drive link.
The utility model has the following advantages and effect:
1, the utility model can with circuit breaker chassis with the use of: under normal conditions, upper valve page is in the lower end of its vertical sliding stroke due to self gravitation effect, lower valve page is in the upper end of its vertical sliding stroke due to the effect of torsion spring elastic force, and upper valve page and lower valve page are in closure state.When pulling circuit breaker chassis to enter service position, trigger the first collision block, the second collision block moves, and then the first drive link is upwards rotated, second drive link rotates simultaneously, first drive link drives upper valve page to move upward by first connecting rod, second drive link drives lower valve page to move downward by second connecting rod, thus upper valve page and lower valve page is opened.
2, the utility model structure is laborsaving, and running resistance is low, and running member stress is little, and the application of grooved guide rail and bearing makes valve page lighter.Mounting structure is ingenious in addition, is convenient to make and install, and the compacting of valve page and grooved guide rail is convenient.
