Abstract
The utility model discloses a front-to-back transposition lifting blackboard relating to a blackboard. The front-to-back transposition lifting blackboard solves the defects that a front blackboard covers the content written on a back blackboard because a rearward-facing blackboard of the traditional lifting blackboard can not move to the front side and is mainly used for matching the teaching work of teachers. The front-to-back transposition lifting blackboard is characterized by comprising blackboard bodies, a frame, connectors, rotators, rotary tables, chains and inclined blanks. The top end of the frame is provided with the rotators, the inclined blanks are fixed on an upper seat, the left side and the right side of the frame are respectively provided with a guide rail, two corners of the upper part of each blackboard body are respectively provided with the connector, and the chains across gears are connected with the connectors and the rotators. According to the front-to-back transposition lifting blackboard disclosed by the utility model, in despite of pulling or pushing the blackboard, one blackboard body can move upwards, that is one blackboard body moves inwards to exchange the position with the other blackboard body, so as to ensure that the current writing blackboard body is always arranged in the front and is not covered by the other blackboard body.
Description
Affiliated technical field
The utility model relates to a kind of teaching aid, particularly can be with the two all prefixion front and back transposition of blackboard blackboard movable up and down.
Background technology
Existing blackboard movable up and down has automatic lifting, automatic blackboard cleaning, reduces functions such as vibration, word is write on earlier on the blackboard, write this piece blackboard shifted onto after full above, below another piece blackboard just moves to naturally, again word is write on this piece blackboard, but it is lower to be positioned at following blackboard, classmates are not easy to see the content of being write below the blackboard, at this moment just blackboard up must be pushed away, make it reach certain height, will cover the content on the blackboard of back after pushing to or covered by the blackboard of front.As: the patent No. is 99246836.1 blackboard movable up and down, at least one pair of plate body that is connected by the part of walking around one group of change gear in it comprises framework and is installed in framework, the axle of each corresponding with a pair of plate body at least change gear is rigidly connected.By above narration as can be seen, the technical solution of the utility model is that the axle with change gear is rigidly connected, thereby makes change gear run-in synchronism, and like this, the various piece of plate body just can move up and down synchronously along its guiding mechanism, thus stuck situation easily when having avoided using.In addition, noise problem big, that rock easily when using when solving the plate body motion can cooperate by concaveconvex structure longitudinally between plate body side and the framework.The patent No. is two frame blooking-hanging type blackboard movable up and down of 200720304873.7, it mainly is by two frameworks, fixed frame and blackboard movable frame, utilize nine word button tracks and nine word button chutes, two frameworks are interlocked to be buckled together, utilize automatic roller bearing lock, hang over mutually together with the buckle teeth bar buckle teeth on the blackboard movable frame, utilize again and be provided with the two symmetrical groups lift clutch in the gap between two frames.Lift clutch is made up of the vapour spring and motion bar, the connecting rod that limit vapour pressure, is connected on fixed frame and the blackboard movable frame, forms complete lifting rectangle blackboard movable up and down flexibly.Make it be fixed on the wall or lifting flexibly on other framework, the blackboard on the wall is lived by dead change, the time spent need not lock.
Summary of the invention
The purpose of this utility model:
Be to solve existing blackboard movable up and down and a blackboard of back can not be put into the front, cause the blackboard of front to give the defective that covers in, and a kind of front and back transposition blackboard movable up and down is provided the content of writing on the blackboard of back.
Technical solutions of the utility model are:
Transposition blackboard movable up and down in front and back mainly is made up of blackboard plate body, framework, connector, rot, rotating disk, chain, oblique base, and wherein: the framework top is equipped with rot, and the installation site is mutually neat with the blackboard edge, and every suit (two) blackboard is joined two rots; The seat of honour and following are arranged in the framework, be fixed with oblique base on the seat of honour, tiltedly the base position is outer, make the blackboard after rising contact with oblique base inclined-plane, one guide rail is arranged respectively about framework, and the width of the guide rail thickness more overlapping than two blackboards is big slightly, is fixed with on the guide rail and leads boots, chain is moved up and down on fixing route, thereby allow stable the sliding up and down of blackboard.Tiltedly base is by cuboid it simultaneously to be whittled into cambered surface to form, and tiltedly on the seat of honour, tiltedly the base end face contacts with the seat of honour base with the nail nail, and tiltedly the base inclined-plane inwardly.Relative motion can take place in rotating disk central authorities and edge.Connector is to be made of connecting rod and rotating disk, and connecting rod one end is fixed on rotating disk central authorities, and disk edge is fixed on the blackboard plate body, and two angles of blackboard plate body top respectively are fixed with a connector.Rot is made up of connecting rod, rotating disk, gear-bearing, fixed bar; Connecting rod one end is fixed on the seat of honour, and the other end is fixed on rotating disk central authorities; Fixed bar is " U " type, and opening portion is fixed on disk edge; Gear-bearing passes fixed bar, is fixed on the central authorities of " U " type.Chain passes " U " type fixed bar, and central authorities are buckled on the tooth of gear-bearing, and two ends are connected in a cover blackboard respectively with on the connecting rod on one side.Chain length is higher two times long slightly than blackboard, makes that two blackboards are not overlapping.
Beneficial effect:
The utility model can allow two blackboards front and back replace, and promptly every blackboard can both can not block the study that influences classmates because of blackboard in front mutually.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
(each the identical point mark among each figure of the design is consistent)
Fig. 1 is an overall structure schematic diagram of the present utility model
Fig. 2 is a rot structural representation of the present utility model
Fig. 3 is a connector construction schematic diagram of the present utility model
Fig. 4 is an oblique blank structure schematic diagram of the present utility model
Among the figure: 1, rot 2, the seat of honour 3, guide rail 4, connector 5, following 6, blackboard plate body 7, framework 8, shell 9, lead boots 10, rotating disk 11, gear-bearing 12, connecting rod 13, fixed bar 14, tiltedly base 15, tiltedly base end face 16, tiltedly base inclined-plane 17, chain
The specific embodiment
The utility model, after teacher has write a blackboard, in the time of will on another piece blackboard, writing, only need blackboard is up pushed away (drawing), after the blackboard that rises touches oblique base, because blackboard still will move upward, but tiltedly the base inclined-plane has propped up blackboard, the distance of adding guide rail is bigger slightly than the thickness of two blackboards, thus blackboard in continuing uphill process, blackboard can move up to highest point along oblique base inclined-plane.In this process, blackboard will inwardly move under the compressing on oblique base inclined-plane, another piece blackboard is located in the outside naturally, because connector and rot all are rotary, so can not cause blackboard to replace because of the rigidity of chain in the process of this transposition.Regardless of drawing or pushing away blackboard, all can there be a blackboard to move upward, promptly all can there be a blackboard inwardly to move, another piece blackboard that swaps out is to guarantee that always the current blackboard of writing can not covered by another piece blackboard in front.
