Abstract
The utility model discloses a single board lifting blackboard, which solves problems of big occupation of wall surfaces of the existing lifting blackboard, etc. The utility model is characterized in that a lifting mechanism which is composed of a roller slide chute, a roller, a fixed pulley, steel wire ropes, a balancing bar, a top wheel, etc. is arranged on the single board lifting blackboard which is composed of a blackboard and a blackboard seat. The single board lifting blackboard with the advantages of simple structure, small occupation of the wall surface, reliable performance and convenient use is suitable for primary and secondary schools and teaching of enterprises.
Description
The utility model relates to a kind of school supply and stationery, particularly relates to a kind of monolithic lift blackboard.
In teaching; usually can use blackboard writes; and traditional fixed monolithic blackboard in use; can not " vary with each individual ", carry out up-down adjustment, so make the writer feel inconvenience deeply; and; the write area of blackboard is used fully, in addition, beholder's visual range is subjected to certain restriction.
Though, already this fixed monolithic blackboard has been done some improvement, design lifting up and down pair of piece blackboard,, many local because of being subjected to environmental limit, still have to abandon using this blackboard, and use traditional fixed monolithic blackboard.
The purpose of this utility model is that a kind of improved monolithic lift blackboard will be provided, and it has not only been realized and can carry out up-down adjustment according to Writer's requirement, and scope of application broadness simultaneously, can also be showed visual range effectively.
Solution of the present utility model to achieve the above object is: monolithic lift blackboard of the present utility model is formed by blackboard and blackboard seat.Two side ends of described blackboard back device respectively have a gyro wheeling concrete chuting, the left side of described blackboard back and the bottom of right-hand part respectively are mounted with a pair of steel wire cable holder, described blackboard seat is made up of steelframe, be separately installed with roller on the channel-section steel frame of its two side, be shaped on groove on the described roller, the left and right sides wall of groove on the described roller and described gyro wheeling concrete chuting is worked in coordination, be respectively equipped with a steel wire cable fixed wheel on the channel-section steel frame of described blackboard seat two sides in addition, all dispose a steel wire cable fixed wheel on the two shaped steel framves at described blackboard seat middle part, the inboard top and the bottom of two shaped steel framves at described blackboard seat middle part all also are equipped with support and rotate the top wheel that connects, the steel wire cable holder of described blackboard back left side and the right-hand part steel wire cable that has been fixedly connected respectively, the other end of described steel wire cable respectively two ends by described steel wire cable fixed wheel and haltere form and are connected and fixed.
Because the utility model improved existing monolithic lift blackboard, between the back of described blackboard and described blackboard seat, set up the elevating mechanism of controlling by haltere, it is simple in structure, easy to use, and it is little to occupy metope, simultaneously, and can arbitrarily lifting in certain scope.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of monolithic lift blackboard of the present utility model.
Fig. 2 is the schematic top plan view of monolithic lift blackboard of the present utility model.
Fig. 3 is the schematic diagram of the blackboard seat of monolithic lift blackboard of the present utility model.
Embodiment to monolithic lift blackboard of the present utility model describes in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, this monolithic lift blackboard is made of blackboard (1) and blackboard seat (2).
Two side ends of described blackboard (1) back are fixed with a gyro wheeling concrete chuting (3), (4) respectively, and the left side of blackboard (1) back and the bottom of right-hand part are equiped with a pair of steel wire cable holder (5), (6) and (5 '), (6 ') respectively.
With reference to Fig. 2, Fig. 3, described blackboard seat (2) is a steel frame, be respectively fitted with a roller (7) on the channel-section steel frame of described blackboard seat (2) two sides, (8), (9), (7 '), (8 '), (9 '), roller (7) on the channel-section steel frame of described blackboard seat (2) two sides, (8), (9), (7 '), (8 '), (9 ') is provided with a groove, described blackboard seat (2) two side channel steelframe upper rollers (7), (8), (9), (7 '), (8 '), the groove of (9 ') respectively with described blackboard (1) back on gyro wheeling concrete chuting (3), (4) left and right sides wall cooperatively interacts, also be respectively fitted with a steel wire cable fixed wheel (10) on the channel-section steel frame of described blackboard seat (2) two sides, (10 '), be installed on a steel wire cable fixed wheel (11) respectively on the two shaped steel framves at described blackboard seat (2) middle part, (11 '), the inboard top and the bottom of the two shaped steel framves at described blackboard seat (2) middle part also are installed on the top wheel (12) that is assemblied on the support respectively, (13), (12 '), (13 '), the steel wire cable holder (5) of the back left side of described blackboard (1) and back right-hand part, (6), (5 '), (6 ') respectively with steel wire cable (14), (15), (14 '), one end of (15 ') forms and is connected and fixed, described steel wire cable (14), (15) the other end is respectively by described steel wire cable fixed wheel (10), (11) the two ends formation with haltere (16) is fixedly connected described steel wire cable (14 '), the other end of (15 ') is also respectively by described steel wire cable fixed wheel (10 '), (11 ') two ends formation with haltere (16 ') is connected and fixed.
Referring to Fig. 1, Fig. 2, Fig. 3, in teaching, use monolithic lift blackboard (1) when writing, can move up and down as required.After hand promotes described blackboard (1) up or down, the gyro wheeling concrete chuting (3) of described blackboard (1) back two side ends, (4) by the roller (7) on described blackboard seat (2) the two side channel steelframes, (8), (9), (7 '), (8 '), the rotation of (9 ') and moving up or down, simultaneously, described haltere (16), (16 ') is by steel wire cable (14), (15), (14 '), the draw of (15 ') descends downwards slowly or upwards rises, at this moment, the top wheel (12) of the inboard top and the bottom of two shaped steel framves, described blackboard seat (2) middle part, (13), (12 '), (13 ') is the back that nestles up described blackboard (1), to stablize described blackboard (1), make it when moving up and down (or writing), does not rock front and back.
