Abstract
The invention discloses a double-side rotating blackboard which has a great function in teaching and researching. The double-side rotating blackboard comprises a blackboard body, a middle shaft, two bearings, an external blackboard frame, a fixing shaft and universal wheels, wherein the middle shaft horizontally passes through the middle part of the blackboard body; the bearings are respectively mounted at the two ends of the middle shaft; the two sides of the external blackboard frame are of vertical pipe shape; a frame rod is horizontally connected with the tops of the external frames on the two sides; lower parts of the external frames on the two sides are vertically connected with a universal wheel bracket; universal wheels are respectively mounted at the two ends of the universal wheel bracket; the bearings at the two ends of the middle shaft are embedded in the middle upper frame bodies of the external frames on the two sides; external rings of the bearings are fixed; the middle shaft and the internal rings of the bearings are in interference fit with each other, so that the 360-degree rotation of the blackboard is realized; the fixing shaft horizontally passes through a middle lower part of the external frame on the right side; a groove is formed in a position, in contact with the side face of the blackboard, of the fixing shaft; the fixing shaft passes through the external frame on the right side and the groove of the blackboard, and then the blackboard is fixed. The double-side rotating blackboard has the advantages of double-side writing of the blackboard, 360-degree rotation of blackboard surfaces and convenience in moving.
Description
Technical field
The present invention relates to a kind of blackboard, particularly relate to a kind of Double-face rotating blackboard.
Background technology
At present, education has become one of topic that the head of a family is concerned about the most, and the head of a family, teacher, student pay much attention to study education.As the saying goes that education is strong, country is strong; Wherein educational facilities receives much concern, and one, a portion platform educational facilities level constantly gushes, and absorbs knowledge fast and efficiently play very large effect for us.Due to Current Domestic, scholar is numerous, and good education equipment can't be popularized comprehensively; Blackboard routine the most common in educational facilities is all be fixed on the wall in classroom, too inflexible, heavy, is unfavorable for that classroom learning activity is used.
Summary of the invention
In order to overcome above-mentioned technical problem, the present invention proposes a kind of Double-face rotating blackboard.
The present invention realizes like this, a kind of Double-face rotating blackboard comprises: universal wheel, outrigger, blackboard body, as further improvement project: described Double-face rotating blackboard also comprises: axis, two bearings, fixed axis, described axis runs through the middle part of described blackboard body, a described bearing is respectively installed at described axis two ends, described axis two ends are embedded in outrigger described in both sides, described fixed axis laterally runs through outrigger described in side, groove is offered in the blackboard body side that described fixed axis is corresponding, and described fixed axis runs through side outrigger and extends in described groove.Described axis and described bearing inner ring interference fit; Described outrigger comprises left and right sides hack lever, upper hack lever, universal wheel connection bracket; Described groove is circular; Described fixed axis diameter is less than described circular groove diameter.
Advantage of the present invention is: structure is simple, simple to operate; 360 ° of rotations of blackboard surface are achieved, two-sided use by axis band dynamic bearing; Blackboard Integral movable is made by universal wheel.
Accompanying drawing explanation
The structural representation of a kind of Double-face rotating blackboard that Fig. 1 provides for better embodiment of the present invention.
The blackboard structure schematic diagram of a kind of Double-face rotating blackboard that Fig. 2 provides for better embodiment of the present invention.
Main Reference illustrates: blackboard body 1, two bearings 2, universal wheel connection bracket 3, axis 4, groove 5, fixed axis 6, universal wheel 7, left side hack lever 8, right side hack lever 9, upper hack levers 10.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to shown in Fig. 1,2.
A kind of Double-face rotating blackboard comprises: blackboard body, two bearings, universal wheel connection bracket, axis, groove, fixed axis, universal wheel, left side hack lever, right side hack lever, upper hack levers.Axis 4 laterally runs through in the middle part of blackboard body 1, and two ends are respectively provided with bearing 2; Left side hack lever 8 is connected universal wheel connection bracket 3 with right side hack lever 9 bottom vertical, and a universal wheel 7 is respectively installed at universal wheel connection bracket 3 two ends, and left side hack lever 8 and right side hack lever 9 top are connected to form the blackboard outrigger of gate by hack lever 10; Axis 4 two ends band bearing 2 is embedded in the hack lever in left side hack lever 8 and right side hack lever 9, and bearing 2 outer shroud is fixed; Fixed axis 6 runs through side hack lever, and the corresponding fixed bar place of blackboard body offers groove 5, and fixed axis 6 extends to groove 5 with this fixed black plate body 1.
In sum, a kind of Double-face rotating blackboard of the present invention and other blackboard are distinguished and are: Double-face rotating blackboard two sides all can be write, and blackboard surface can 360 ° of rotations, two-sidedly in the middle of Double-face rotating blackboard removable placement classroom when classroom learning is movable all can watch.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
