Abstract
The utility model discloses a movable teaching whiteboard. The movable teaching whiteboard comprises supports (1) and a board body (2). The supports and the board body are fixedly connected together. Movable wheels of the supports (1) are installed at the bottom ends of the supports (1). The movable teaching whiteboard is characterized in that magnet fixing mechanisms are arranged on the upper edge of the board body (2), the magnet fixing mechanisms are composed of magnets (3), winding ropes (4), winding shafts (5), left supporting seats (6), right supporting seats (7) and fixing bolts (8). The left supporting seats (6) and the right supporting seats (7) are fixed on the upper edge of the board body (2), the winding shafts (5) are movably arranged between the left supporting seats (6) and the right supporting seats (7), the winding ropes (4) are wound on the winding shafts (5), the winding ropes (4) are connected with the magnets (3), the fixing bolts (8) are arranged on the supporting seats through holes, and the fixing bolts (8) correspond to the winding shafts (5) in position. The movable teaching whiteboard is simple in structure, the auxiliary parts like the magnets are not prone to being lost, and convenience is brought to a user.
Description
Technical field:
The utility model relates to the educational aid technical field, is a kind of Mobile Teaching blank specifically.
Background technology:
Because whiteboard structure is simple, easy to use, cost is low, is used widely in fields such as participatory teaching, discussion; Used blank generally is comprised of support and plate body two parts, fixedly the planar materials such as teaching notes or displaying works bothers, large material generally adopts two ends to clamp with clip, little material generally adopts magnetite to hold, this mode will be equipped with a plurality of auxiliaries, auxiliary rapid wear and easily losing brings pretty troublesome to the user.
The utility model content:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of Mobile Teaching blank is provided, and mainly solves existing blank and need be equipped with the problem that auxiliary uses trouble.
The technical solution of the utility model is: a kind of Mobile Teaching blank, it comprises support and plate body, the two is fixed together, movable pulley is installed in the bottom of support, its special character is to establish the magnetite fixed mechanism in the upper edge of plate body, the magnetite fixed mechanism is by magnetite, winding rope, twine axle, left support abutment, right support abutment and set bolt form, left support abutment, right support abutment is fixed on the upper edge of plate body, at left support abutment, the winding axle is established in activity between right support abutment, twine on the axle and curl wiring, winding rope connects magnetite, by the hole set bolt is installed on bearing, and set bolt is corresponding with the winding shaft position.
Further, described magnetite fixed mechanism is N, and N is more than or equal to 1.
Compared with the prior art a kind of Mobile Teaching blank described in the utility model has following good effect, and simple in structure, the auxiliaries such as magnetite are difficult for losing, and bring convenience to the user.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the utility model in detail.
Embodiment 1, referring to Fig. 1, be processed into support 1 and plate body 2, movable pulley is installed in the bottom of support 1, at the upper edge of plate body 2 fixed installation left support abutment 6 and right support abutment 7, offer symmetrically lateral aperture on left support abutment 6 and the right support abutment 7, at left support abutment 6, the movable installation twined axle 5 in the lateral aperture of right support abutment 7, left support abutment 6, distance between the right support abutment 7 is less than twining axle 5, twining axle 5 can rotate in the lateral aperture of left support abutment 6 and right support abutment 7, curl wiring 4 at winding axle 5, winding rope 4 connects magnetite 3, is offering upright opening above the left support abutment 6 or offer upright opening above right support abutment 7, by upright opening set bolt 8 is installed, set bolt 8 is corresponding with winding axle 5 positions, is used for the fixing axle 5 that twines; By magnetite 3, winding rope 4, twine axle 5, left support abutment 6, right support abutment 7, set bolt 8 and form the magnetite fixed mechanism, the quantity of magnetite fixed mechanism can be set as required, general 2-3 is individual for well; The plate body 2 that will install at last the magnetite fixed mechanism is installed on the support 1 by prior art, forms a kind of Mobile Teaching blank of the present utility model.
A kind of Mobile Teaching blank described in the utility model during use, unclamps set bolt, pull with hand magnetite, twine the axle rotation winding rope is unclamped, need the position when magnetite arrives, tighten set bolt, twine axle and stop the rotation, this moment is with magnetite fixedly teaching notes or showing material; Take off material after being finished, unclamp set bolt, rotate the winding axle by hand, under the drive of winding rope magnetite is drawn high, magnetite arrives the top, tightens set bolt.
Claims (2)
1. Mobile Teaching blank, it comprises support (1) and plate body (2), the two is fixed together, movable pulley is installed in the bottom of support (1), it is characterized in that establishing the magnetite fixed mechanism in the upper edge of plate body (2), the magnetite fixed mechanism is by magnetite (3), winding rope (4), twine axle (5), left support abutment (6), right support abutment (7) and set bolt (8) form, left support abutment (6), right support abutment (7) is fixed on the upper edge of plate body (2), in left support abutment (6), activity is established and is twined axle (5) between right support abutment (7), twine on the axle (5) and curl wiring (4), winding rope (4) connects magnetite (3), by the hole set bolt (8) is installed on bearing, set bolt (8) is corresponding with winding axle (5) position.
