Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Figure 1-5, the utility model discloses a kind of blackboard assembly, comprises blackboard 1, framework 2, telescopic component 3 and hairbrush 4.
Described blackboard 1 is embedded in described framework 2; The bottom of the top edge of described framework 2 and the top of lower limb respectively symmetry offer slide rail, glidepath, and the inner side of the left hand edge of described framework 2 and the inner side of right hand edge respectively symmetry offer left slide rail, right slide rail; Be provided with top shoe 5 in described upper slide rail, in described glidepath, be provided with sliding block 6, in described left slide rail, be provided with left slider (not shown in FIG.), in described right slide rail, be provided with right slide block (not shown in FIG.).When described telescopic component 3 length direction two ends respectively by top shoe 5 and glide fast 6 be slidably arranged in described upper slide rail and described glidepath time, the length direction that described telescopic component 3 can be parallel to described blackboard 1 moves left and right.Those skilled in the art are easy to expect the two ends of described telescopic component 3 length direction to be arranged in described left slide rail and described right slide rail respectively by left slider and right skid.
When the shiny surface of described hairbrush 4 is fixed on described telescopic component 3, the bristle face of described hairbrush 4 abuts on described blackboard 1.
The two ends of telescopic component 3 length direction are respectively arranged with projection, the bottom of top shoe 5 and the top of sliding block 6 are provided with the groove fastened with described projection, make the two ends of telescopic component 3 length direction to adopt buckle to be connected with described top shoe 6 and described sliding block 6 respectively.Also at the two ends of telescopic component 3 length direction, external screw thread can be set respectively, and to arrange with described external screw thread to the internal thread of adaptation at the top of the bottom of top shoe 5 and sliding block 6, the two ends of telescopic component 3 length direction can be adopted with described top shoe 6 and described sliding block 6 respectively and be threaded.
The back side of described telescopic component 3 and the shiny surface of hairbrush 4 are provided with adhesive linkage 8; The shiny surface of described hairbrush 4 and the back side of described telescopic component 3 are bonded by respective adhesive linkage 8; The front of described telescopic component 3 is provided with handle 10.
Described handle 10 is provided with spiral helicine concave convex texture.
Be fixed with dust catcher 9 in the internal cavities of described telescopic component 3, the back side of described telescopic component 3 and the shiny surface of described hairbrush 4 all offer through hole 7.
Described telescopic component 3 comprises the first hollow sheeting 31 and the second hollow sheeting 32, described first hollow sheeting 31 is set in described second hollow sheeting 32 slidably and can does stretching motion along the length direction of described second hollow sheeting 32, and described first hollow sheeting 31 interlinks with described second hollow sheeting 32.Each hollow sheeting forms by back side arcuate plate 33 and the engaging of front arcuate plate 34.Wherein, described back side arcuate plate 33 is provided with described through hole 7 and described adhesive linkage 8, described front arcuate plate 34 is provided with described handle 10.
