Abstract
The utility model relates to the supporting device of a movable blackboard that can be connected to the wall. The device comprises a supporting seat connected to the wall, and a vertical lead rail and a transverse lead rail are arranged in front of the supporting seat. The blackboard is installed on the transverse lead rail. A heavy object that can move in the inner cavity of the wall balances the blackboard. The blackboard can move vertically or horizontally when vertical or horizontal external force is applied on the blackboard. The device makes the blackboard surface of the blackboard fully utilized, and is favorable for teachers to choose the best writing position. The utility model has the advantages of high speed, simple device and convenient installation, and is suitable for blackboards made of wood, metal plates, etc.
Description
The utility model relates to a kind of supporting arrangement that is connected to the Reelable blackboard on the wall.
The blackboard that use present most places to operate schools is fixing can not to be moved on the plane on the wall, and therefore, teacher's writing on the blackboard inconvenience can not make full use of the space of a whole page of blackboard, and the time that erases the board in the classroom is many, influences the quality and the speed of writing on the blackboard.
The purpose of this utility model provides a kind of simple in structure, makes and installs to be relatively easy to device that blackboard is moved near wall plane, thereby make the teacher can be in best writing on the blackboard position, makes full use of the space of a whole page of blackboard.
The device that the utility model proposes is achieved in that this device has a supporting base that is welded into by angle steel, the front of supporting base is symmetrically installed with two pairs of vertical guide sheaves, along what the vertically-guided crop rotation moved both vertically two vertical guide rails are arranged, the upper and lower side of two vertical guide rails respectively welds a baffle plate, the stroke of restriction vertical guide rail, laterally be welded with two cross-arms at the positive middle part of two vertical guide rails, horizontal guide sheave is equipped with at the two ends of cross-arm.The middle part of supporting base is welded with pulley and props up part, prop up at pulley pulley is housed on the part, steel wire rope one end on pulley ties up on the lower baffle plate of vertical guide rail, the other end is a weight, the quality of this weight can be adjusted, and the supporting base of this device is fixed in the wall that satisfies suitable thickness and height with concrete.The supporting base of device is positive concordant with metope, and weight can move up and down in the wall inner chamber.Cross slide way inserts horizontal guide sheave from an end of cross-arm, sideboard is loaded onto at the cross slide way two ends, blackboard just is installed on the band steel at cross slide way middle part, blackboard is applied the external force of a vertical direction, blackboard can move in the vertical direction, and blackboard is applied a side direction external force, and blackboard can move by along continuous straight runs, make blackboard be in only position, make things convenient for teacher's writing on the blackboard.
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is the side partial sectional view that the utility model is connected to wall.
Below in conjunction with accompanying drawing the utility model is described in detail:
The device that the utility model proposed (Fig. 1) props up part (12), steel wire rope (14), weight (15) by supporting base (9), vertical guide sheave (10), vertical guide rail (2), overhead gage (1), lower baffle plate (13), cross-arm (3), horizontal guide sheave (4), cross slide way (5), band steel (6), end plate (7), sideboard (8), pulley (11), pulley and forms.Supporting base (9) is six frameworks that are welded into by angle steel, and its middle part is welded with pulley and props up part (12), is used for installing pulley (11), in the front of supporting base (9) two pairs of vertical guide sheaves (10) is installed.Two vertical guide rails (2) are stuck in the middle of two pairs of vertical guide sheaves (10), vertical guide rail (2) adopts angle steel to make, the two ends lower baffle plate (1) of burn-oning, (13), the middle part is weldering two cross-arms (3) laterally, horizontal guide sheave (4) is equipped with at the two ends of cross-arm (3) respectively, cross slide way (5) is made by two angle steel, be stuck in the middle of two pairs of horizontal guide sheaves (4), the centre is welded with two band steels (6), two ends are welded with end plate (7), the two ends end plate (7) of cross slide way (5) is gone up sideboard (8) is installed, and blackboard (19) (Fig. 2) just is installed on the middle band steel (6) of cross slide way (5).Steel wire rope (14) is on pulley (11), one end be the lower baffle plate (13) of vertical guide rail (2), the other end be weight (15), the quality of weight (15) can be adjusted, and vertical guide sheave (10), horizontal guide sheave (4), pulley (11), sideboard (8) adopt the standard fasteners assembling.The supporting base of this device (9) embeds in the wall (16) (Fig. 2), the front of supporting base (9) is concordant with the metope of wall (16), cast concrete (17) between supporting base (9) and the wall (16), leave in the bottom of supporting base (9) chamber (18) within the walls, weight (15) can move up and down in chamber (18) within the walls.Blackboard (19) vertical direction is applied external force, at this moment destroyed by weight (15), vertical guide rail (2), cross slide way (5), the balance that blackboard (19) forms, the displacement that blackboard (19) promptly produces vertical direction, blackboard (19) is applied the side force of suitable size, the displacement that blackboard (19) promptly produces horizontal direction, firmly appropriate, blackboard (19) can produce the displacement of vertical direction and horizontal direction simultaneously, in case external force disappears, blackboard (19) promptly stops motion, reach new position, blackboard (19) vertically, the extreme displacement of horizontal direction is respectively by overhead gage (1), lower baffle plate (13), sideboard (8) is realized.
The device that the utility model proposed can make blackboard move, thereby make the teacher can be in best writing on the blackboard position along vertical, horizontal direction, more fixed blackboard comes, can improve the quality and the speed of writing on the blackboard, make full use of the space of a whole page of blackboard, reduce on the classroom erasing the board the time.Device is carried out in advance, as long as supporting base is fixed within the walls, blackboard is installed on the band steel at cross slide way middle part during use, thereby it is easy for installation, with pulling, carry, push away the position that can change blackboard, simple to operate, be applicable to the blackboard made from materials such as timber, iron plates.
The device that the utility model proposed, its supporting base (9) should be welded into No. 4 or 5 bugle steel, 250 millimeters to 500 millimeters of positive face width and Gao Ge, dark 150 millimeters to 300 millimeters, vertical guide rail (2) should be used 4 bugle steel, long 800 millimeters/to 1500 millimeters, cross-arm (3) should be used 4 bugle steel, and long 500 millimeters to 1000 millimeters, cross slide way (5) should be used 3 bugle steel, its length dimension is decided according to blackboard (19), just is in dead ahead of the present utility model during teacher's writing on the blackboard and takes back or take over the position.
