Description
Technical field
The utility model relates to a kind of didactic works frame, belongs to realia technical field of structures.
Background technology
Teacher is when giving lessons writing on the blackboard, and normally hold books writing on the blackboard on the other hand on the other hand, the time one is long, and arm can be made to produce sour swollen sense, accumulate over a long period and can form the diseases such as arthritis, at present, occurred several writing on the blackboard bookshelf on the market, but complex structural designs, and take blackboard space, use trouble.
Summary of the invention
The purpose of this utility model is the weak point solving prior art existence, and provide one can use as book bracket when teacher's writing on the blackboard, easy to use and flexible, does not take the didactic works frame in blackboard space.
The utility model is achieved through the following technical solutions:
A kind of didactic works frame, its special character is to comprise the rotating shaft 1 being installed on blackboard slot 3 one end, the outer cover of rotating shaft 1 is provided with the blowout patche 2 that can rotate along rotating shaft 1, the outer wall of blowout patche 2 is provided with the horizontal arm 4 paralleled with blackboard slot 3, horizontal arm 4 is cylindrical, the outer cover of horizontal arm 4 is provided with the lasso 5 that can horizontally slip along the length direction of horizontal arm 4, first upright arm 6 perpendicular with horizontal arm 4 is installed directly over lasso 5, the top of the first upright arm 6 is socketed with perpendicular with it and telescopic telescopic arm 7, the end of telescopic arm 7 is socketed with second upright arm 8 perpendicular with it, the top of the second upright arm 8 is provided with the clamping device for clamping books, clamping device comprises the top being sheathed on the second upright arm 8 and the sleeve 11 that can rotate around it, sleeve 11 is provided with the rack 9 that cross section is L-type, the L-type vertical plane both sides of rack 9 are provided with the jig arm 10 for clamping books,
One end of described horizontal arm 4 is provided with hook 12;
Between described first upright arm 6 and telescopic arm 7 and the hollow bushing 13 being all L-type by cross section between telescopic arm 7 and the second upright arm 8 be rotationally connected.
A kind of didactic works frame of the present utility model, reasonable in design, when not using, can be rotated around the axis horizontal arm, horizontal arm is made to be positioned at the outside of blackboard, do not take blackboard space, when needs use as bookshelf, only horizontal arm need be rotated, horizontal arm is made to be positioned at directly over blackboard slot, then the first upright arm is dragged, first upright arm is moved along horizontal arm length direction, to be adjusted to after suitable location with the first upright arm as fulcrum telescopic arm, then regulate the length of telescopic arm to suitable location, then books are positioned on clamping device, rack can be rotated, be adjusted to proper angle, in sum, the utility model reasonable in design, flexible and convenient to use, liberation teacher takes scribe's arm, and do not take blackboard space, there is good application prospect.
