Background technology
The teaching sold in existing market is all one piece erasable with white plate, and write area is little, takes up an area relatively large again, although what can meet less occasion writes needs, but in most of the cases, it is little that it writes scope, need repeatedly erasable writing process, bring much inconvenience to use.
On the basis retaining original whiteboard structure and volume, how to expand write area, it is to increase space utilising efficiency, better meet the use needs of numerous clients, just become the problem that the utility model is wanted to solve.
Summary of the invention
In view of the deficiency that said structure exists, the utility model aim to provide a kind of write area big, use and flexibly, do not need repeatedly erasable double-deck mobile white plate, to meet the service requirements of user, it is to increase the space utilising efficiency of white plate, reduce erasable number of times.
The utility model is achieved through the following technical solutions:
A kind of double-deck mobile white plate, comprises fixing white plate, is positioned at fixing white plate front end and corresponding with fixing white plate, the highly identical white plate of movement, and the transmission rig being connected between fixing white plate and mobile white plate; Transmission rig comprises roller, guide rail, hanger and position-limit mechanism; Guide rail is fixed on the top of fixing white plate; Roller is positioned at above guide rail, and roller matches with guide rail; Hanger one end is fixed on mobile white plate, and the other end is connected with roller; Position-limit mechanism is connected on fixing white plate and mobile white plate.
The length of described fixing white plate is at least the twice of mobile white plate length.
Interconnective roller and hanger are more than two, and interconnective roller more than two and hanger are evenly distributed on guide rail.
Described position-limit mechanism comprises two back up pads, two clamps and two elastic spacing blocks, and two back up pads are connected to the left and right two ends of side after mobile white plate, and two back up pads keep levels; Two clamps are separately fixed in two back up pads, and the fixing white plate corresponding with clamp is provided with the groove of horizontal direction, and clamp front end is given prominence in back up pad front end and is arranged in groove, and before outstanding clamp, end face is provided with card groove;Two elastic spacing blocks are embedded in groove and are separately fixed at the left and right two ends of groove.
Also comprising two plastic bearings in described position-limit mechanism, horizontal support is in the back up pad at left and right two ends respectively for two plastic bearings, and the circumference face of plastic bearing contacts with the surface of fixing white plate.
The useful effect of the mobile white plate of bilayer described in the utility model comprises:
1, the combination of roller and hanger is utilized, mobile white plate is formed hanging, make the most even by power, reasonable of mobile white plate, simultaneously, by plastic bearing, the mobile lower end of white plate is supported, ensure that mobile white plate is in vertical state all the time, the phenomenon such as can not produce lower end deflection, rock, ensure that the smoothness of mobile white plate moving process and handiness.
2, by cooperatively interacting between groove two ends elastic spacing block and mobile clamp, mobile white plate can effectively be held when moving to outermost end, ensure that and the security that mobile white plate uses avoid the generation of the accidents such as mobile white plate slippage.
3, the double-deck mobile white plate that front and back superposition is placed, under the prerequisite not increasing floor space, effectively improves write area, reduces the frequency of wiping, for big area writing on the blackboard provides conveniently.
4, remain handiness and accessibility that the white plate of original movement uses, enriched ways of writing, various place can be adapted at and write use.
Accompanying drawing explanation

Fig. 2 is right side of the present utility model part sectioned view;
Fig. 3 is the B place partial enlargement schematic diagram of Fig. 2;
Fig. 4 is that the A of Fig. 2 is to partial enlargement sectional view.
Embodiment
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, the utility model is further described:
The mobile white plate of bilayer described in the utility model, comprises fixing white plate 2, is positioned at fixing white plate 2 front end and corresponding with fixing white plate 2, the highly identical white plate 1 of movement, and the transmission rig being connected between fixing white plate 2 and mobile white plate 1. Wherein, the length of fixing white plate 2 is the twice of mobile white plate 1 length, mobile white plate 1 is by transmission rig in the fixing left and right movement in white plate 2 front, and that just can dodge open fixing white plate 2 writes scope, ensure that the gamut of fixing white plate 2 and mobile white plate 1, normally uses.
Transmission rig comprises two groups of interconnective rollers 4 and hanger 3, and a guide rail 5 and a position-limit mechanism. Guide rail 5 is fixed on the top of fixing white plate 2, and roller 4 matches to merge with guide rail 5 and is positioned at above guide rail 5. Two groups of interconnective rollers 4 and hanger 3 lay respectively at the two ends, top of mobile white plate 1, and hanger 3 one end is fixed on mobile white plate 1, and the other end is connected with roller 4.
Position-limit mechanism is between mobile white plate 1 and fixing white plate 2, and position-limit mechanism is connected on fixing white plate 2 and mobile white plate 1. In this example, position-limit mechanism comprises two back up pads, 6, two clamps, 8, two elastic spacing blocks 9 and two plastic bearings 7. The shape of back up pad 6 is ' L ' shape, two ' L ' shape back up pads 6 are separately fixed at the left and right two ends of the rear side of mobile white plate 1 by short limit plane, the long limit plane of two back up pads 6 keeps level and mutually on same horizontal plane, gap is left with fixing white plate 2 surface in the outer face of long limit plane. Clamp 8 is dull and stereotyped shape, two clamps 8 are separately fixed on the bottom surface of long limit plane of two back up pads 6, the fixing white plate 2 corresponding with clamp 8 is provided with the groove 11 of horizontal direction, clamp 8 front end is given prominence in the front end of back up pad long limit plane and is arranged in groove 11, and before outstanding clamp 8, end face is provided with card groove.Two elastic spacing blocks 9 are embedded in groove 11 and are separately fixed at the left and right two ends of groove 11, and elastic spacing block 9 is the block that a front end is provided with elasticity sheet, rear end is a supporter, and in groove 11, the elasticity sheet of two elastic spacing blocks 9 is put relatively. For preventing mobile white plate 1 time end to tilted or rock, two back up pads 6 long limit plane top also respectively horizontal support have a plastic bearing 7, the circumference face of plastic bearing 7 contacts with the surface fixing white plate 2.
During use, mobile white plate 1 is by the support of hanger 3 and roller 4, upper left at guide rail 5, move right, simultaneously, plastic bearing 7 in back up pad 6 is supported on fixing white plate 2 surface all the time, and roll back and forth along with the movement of mobile white plate 1, mobile white plate 1 is subject to the anchorage force in two directions all the time, avoids mobile white plate 1 time end and rocks or the phenomenon such as crooked. when mobile white plate 1 moves to one of them end face of fixing white plate 2, clamp 8 front end being arranged in groove 11 contacts with the elastic spacing block 9 on groove 11 end face, elasticity sheet on elastic spacing block 9 is held in the card groove of end face before clamp 8, mobile white plate 1 cannot continue to move forward, mobile white plate 1 position is defined, equally, when mobile white plate 1 moves to the end face of the other one end of fixing white plate 2, also can be stopped by the elastic spacing block 9 of other one end, thus prevent mobile white plate 1 on a left side, move right the phenomenon from slippage guide rail 5 that may occur in process, ensure that the security of mobile white plate 1 moving process.
