Description
The utility model relates to a kind of blackboard wiping utensil, and especially the remote control automatic blackboard eraser is wiped away deduster, can with the supporting use of various writing blackboards.
Existing blackboard is still by manually using wiping board wiping, dust from flying, misfortune and teachers and students' health.The design of several blackboard wiping machines of Tui Chuing in recent years, respectively because of adopting 220 volts of non-safe voltages or adopting many magnetic valves and electromagnet, cause that functional reliability is poor, noise is big, heavy or can not be on the orientation in length and breadth of blackboard selectable deficiency such as wiping regional area, and the application that do not put it over.
The purpose of this utility model provide a kind of adopt safe voltage be power, selectively the remote control blackboard wiping any regional area on the orientation or the disposable complete fast remote control automatic blackboard eraser of wiping are wiped away deduster in length and breadth.
The technical solution of the utility model is: the remote control automatic blackboard eraser is wiped away deduster and is made up of remote control, walking dolly and upper and lower guide rail, and the dolly casing relies on one, and initiatively rubber tire, three driven rubber tires and a horizontal rubber tire operate in bolting on the guide rail of blackboard upper and lower.Main motor is paid with worm and wormwheel, gear mesh and initiatively rubber tire connect successively and link and all be installed on the top spacer of little box body.Main motor also is connected with long wiping roller and square shaft by belt and links.Length wiping roller, square shaft and central authorities have interior square hole to be enclosed within on the square shaft and the weak point that can slide up and down wipes roller and lifting motor, worm gear reducer, adjustable pulley are installed on the swing span, and swing span is installed in the middle part of little box body and can swings around the vertical shaft of oneself.Be installed in swing motor on the little box body and worm and wormwheel and pay and be connected to each other, the latter is connected with swing span by connecting rod again and links, and remote control swing motor, can make and longly wipe roller or the short roller of wiping is close to blackboard respectively or is separated with blackboard simultaneously.Pull rope tightly is enclosed within on the single sheave and adjustable pulley of worm gear reducer, indicator lamp is housed and is sleeved on the side that the lasso of lacking on the vertical shaft of wiping roller bottom and swing span is fixed in pull rope, the remote control lift motor can be regulated short vertical height and position of wiping roller, so that the regional area on the selectable blackboard wiping.Main motor, lifting motor and swing motor all are to be the DC micromotor of power with the safe voltage.Be inlaid with two insulation separately, single-side exposed transmission of electricity copper bar in the bottom surface of upper rail, be installed in the upper outside of little box body with the electrical contact that is subjected to of its Elastic Contact.Dust gathering arrester, dust catcher and elastic packing plate are installed in the bottom of little box body.On little box body, sealing case lid from transparent windows a to side that can open and inlay is housed.
Owing to adopt technique scheme, the utlity model has simple in structure, safe and reliable, in light weight, noise is little, convenient and swift, eliminate dust, the good environment of creating classroom instruction, remote-controlled selection Automatic erasing blackboard advantage such as any regional area on the orientation or disposable fast full wiping to the left or to the right in length and breadth.When time spent not long period, little box body can be lifted slightly, can from upper and lower guide rail, take out, preserve in the packing box of packing into.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structure principle chart of the present utility model (shedding case lid).
Fig. 2 is the left view (case lid is opened 90 degree) of Fig. 1.
As depicted in figs. 1 and 2, the remote control automatic blackboard eraser is wiped away deduster and is made up of remote control, walking dolly and upper and lower guide rail, and little box body (24) relies on one, and initiatively rubber tire (12), three driven rubber tires (2) and a horizontal rubber tire (25) operate in bolt (32) and be fixed on the upper rail (31) and lower guideway (1) of blackboard upper and lower.Main motor (21) transmission worm and wormwheel is paid (10) and gear mesh (11) and driving active rubber tire (12) and is moved to the left or to the right along upper rail (31) and lower guideway (1), and they all are installed on the upper spacer of little box body (24).Main motor (21) also has square hole to be enclosed within square shaft (22) the short synchronous forward and reverse rotation of roller (18) of wiping of going up and can slide up and down by long roller (9), square shaft (22) and the central authorities of wiping of belt (23) transmission.Length is wiped roller (9), square shaft (22), short wiping roller (18) and lifting motor (6), worm gear reducer (5), adjustable pulley (15) and is installed on the swing span (4), and swing span (4) is installed in the middle part of little box body (24) and can swings around the vertical shaft of oneself.Be installed in swing motor (8) on the little box body (24) and worm and wormwheel and pay (7) and be connected to each other, the latter is connected with swing span (4) by connecting rod (20) again and links.Remote control swing motor (8), transmission worm and wormwheel are paid (7) and connecting rod (20), can be driven swing span (4), make longly to wipe roller (9) or shortly wipe that roller (18) is close to blackboard respectively or the while separates with blackboard.Pull rope (19) tightly is enclosed within on the single sheave and adjustable pulley (15) of worm gear reducer (5).Indicator lamp (16) is housed and is sleeved on the side that the lasso (17) of lacking on the vertical shaft of wiping roller (18) bottom and swing span (4) is fixed in pull rope.Remote control lift motor (6), driving worm gear reducer (5) and pull rope (19) can be regulated short vertical height and position of wiping roller (18).When starting lifting motor (6), exclusive circuit can start swing motor (8) automatically, the short roller (18) of wiping is separated automatically, to guarantee its unresisted lifting with blackboard (3).See through the transparent windows (28) be embedded on the case lid (27), can see short that indicator lamp (16) shows clearly and wipe the residing vertical and horizontal of roller (18) position, so that wiping selected regional area on blackboard exactly.Main motor (21), lifting motor (6) and swing motor (8) all select for use voltage less than 25 volts DC micromotor.Be inlaid with two insulation separately, single-side exposed transmission of electricity copper bar (30) in the bottom surface of upper rail (31), be installed in the upper outside of little box body (24) with the electrical contact (29) that is subjected to of its Elastic Contact.In the distribution box that hangs on one jiao in classroom, 220/25 volt transformer is housed, carries the electric current of 25 volt-amperes of full voltages by insulated conductor to transmission of electricity copper bar (30).At the electric elements box that is positioned at dolly casing (24) top rectifier, remote-receiver and surface-mounted integrated circuit are housed.Dust gathering arrester (14), dust catcher (13) and elastic packing plate (26) are installed in the bottom of little box body (24).Being equipped with on little box body (24) can be to the sealing case lid (27) of side unlatching.The terminal travel switch all is equipped with at the two ends that are positioned at blackboard (3) and swing span (4), when little box body (24) or the short roller (18) of wiping when moving to terminal, all automatic reverse is moved.The lecturer hands small and exquisite remote controller, can be in distance blackboard (3) the place ahead 50 meters optional position, blackboard wiping (3) any regional area or disposable complete fast to the left or to the right wiping the on the orientation in length and breadth.When time spent not long period, little box body can be lifted slightly, can from upper and lower guide rail, take out, preserve in the packing box of packing into.
