The specific embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 1～shown in Figure 7,1-side plate, 2-mount pad, 3-switch contact, 4-cam, 5-switch shrapnel, 6-horizontal rotating shaft, 7-drift angle, 8-hypotenuse, 9-sense switch, 10-snap ring, 11-back-moving spring, 12-locking bar, 13-sprocket wheel, 14-rocking handle, 15-locating slot.
A kind of mechanical column lock protective device of intelligent mobile rack comprises being weldingly fixed on intensive the mount pad 2 on the side plate 1, this mount pad be by two be "
" type and "] " sheet material of type fastens mutually and integrally welded, is provided with horizontal rotating shaft 6 in the mount pad, attaching nut's (not shown) behind the connecting hole of mount pad 2 is passed in this horizontal rotating shaft the inner, can prevent that by this nut horizontal rotating shaft 6 breaks away from connecting hole; The horizontal rotating shaft exposed junction is fixed with and can drives the rocking handle 14 that horizontal rotating shaft rotates.Welding stationary cam 4 on the horizontal rotating shaft in the mount pad, this cam such as Fig. 6, shown in Figure 7 have drift angle 7 and hypotenuse 8 structures on its outer round surface.
Described cam 4 belows are provided with vertically arranged locking bar 12, and this locking bar top is provided with the locating slot 15 that can be embedded cam 4, and this locating slot can be used to guarantee the contact position of cam and locking bar, prevent cam 4 double swerve and breaking away from locking bar 12 in rotation process; The locking bar bottom is passed mount pad 2 and is installed in intensive the sprocket wheel 13 on the side plate 1 and engages or break away from, lock or unlocking action to finish, on locking bar 12, also be fixed with simultaneously snap ring 10, locking bar is arranged with the two ends back-moving spring 11 of pushing tow on snap ring and mount pad 2 respectively outward, can drive the locking bar rising through this back-moving spring resets, perhaps also can be provided with jack on locking bar, back-moving spring 11 tops directly link in this jack, reach pushing tow locking bar purpose equally.Moving downward of locking bar 12 is to drive cam 4 rotations by shaking rocking handle 14, makes cam drift angle 7 contact locking bars 12 tops, and the elastic force that this hour locking lever overcomes back-moving spring 11 is fastened on downwards on sprocket wheel 13 gears, to reach the purpose of locking; Moving upward of locking bar 12 is to drive cam 4 rotations by shaking rocking handle 14, makes cam hypotenuse 8 contact locking bar tops, and this hour locking lever breaks away from sprocket wheel 13 under the elastic force effect of back-moving spring 11, to reach the purpose of unblanking.
