In above-mentioned accompanying drawing, Reference numeral corresponding component title is as follows:
1-mounting plate, the long free-sliding spline axle of 201-, the left locating piece of 202-, 203-support rail, the right locating piece of 204-, 301-strut bar, the short free-sliding spline axle of 302-, 303-back-up block, 401-drawer sliding plate, 402-block, 403-bottom plate.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to figure 1, mounting plate 1, shape is tabular, long 298mm, wide 250mm, thick 5mm, and wherein one section has chimb as shown in the figure.
With reference to figure 2, cross bar assembly, comprises long slippage castellated shaft 201, left locating piece 202, support rail 203, right locating piece 204.Left locating piece 202, right locating piece 204 upper end are connected in the mode be threaded with mounting plate 1 respectively, and the end face distance of its left locating piece 202 and the right locating piece 204 vertically chimb of axis and mounting plate 1 is 90mm, is convenient to fold.Long free-sliding spline axle 201 is connected with support rail 203 through strut bar 301, left locating piece 202, and support rail 203 is connected with right locating piece 204.
With reference to figure 2, cross bar assembly, it act as: the adjustment of mounting plate 1 angle is with fixing, when from left, long slippage spline 201 being pulled out support rail 203, when long free-sliding spline axle 201 two place's male spliness respectively with the female splines of strut bar 301 and left locating piece 202 without when engaging, the angle of adjustable mounting plate 1.When reaching the best use angle of user, then be pressed in left locating piece 202 by long free-sliding spline axle 201, the male splines of this duration free-sliding spline axle 201 engages completely respectively at the female splines of strut bar 301 and left locating piece 202, realizes the fixing of mounting plate 1 angle.Cross bar assembly can realize mounting plate 1 adjusting angle within the scope of 315 °.
With reference to figure 2, strut bar assembly, comprises strut bar 301, short free-sliding spline axle 302, back-up block 303, and its effect is mainly: regulate, the angle of fixed pedestal bar 301 with bear moment of flexure.Back-up block 303 is connected threadably with bottom plate 403, and short free-sliding spline axle 302 is connected with back-up block 303 through strut bar 301.During use, short free-sliding spline axle 302 is pressed into from left to right, when short free-sliding spline axle 302 male splines respectively with the female splines of strut bar 301 and back-up block 303 without when engaging, the angle of adjustable support bar 301.When angular adjustment use angle best to user, short free-sliding spline axle 302 is pressed into back-up block 303 from right to left, now the male splines of short free-sliding spline axle 302 engages completely with the female splines of strut bar 301 and back-up block 303 respectively, realizes strut bar 301 angle and fixes.The maximum angle that strut bar assembly can regulate is 180 °.
With reference to figure 2, bottom plate assembly, comprises block 402, drawer sliding plate 401, bottom plate 403.The long 308mm of drawer sliding plate 401, wide 225mm, thick 9mm.The long 351mm of bottom plate 403, wide 230mm, thick 14mm, and in bottom plate 403 hollow to hold drawer sliding plate 401.Bottom plate assembly act as: the different demands of user to bottom plate length regulating the length of bottom plate assembly to adapt to different building shape increase bottom plate usable area simultaneously, and maximum extending length is 210mm, and now lower plate overall length is 565mm.This assembly is provided with 2 blocks 402, is placed in drawer sliding plate 401 the right and left respectively and apart from drawer mouth 13mm place, at loading drawer sliding plate 401, then 2 blocks 402 is loaded the two ends, left and right of bottom plate 403.
With reference to figure 3, when user finish using need folding time, only need that female splines in adjusting support frame assembly has the long slippage castellated shaft 201 of meshing relation, portable supporting plate can fold complete by short free-sliding spline axle 302.Long slippage castellated shaft 201, short free-sliding spline axle 302 and the number of teeth of female splines matched with it are all 24 teeth.
