Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b):

as shown in figures 1 to 7: a combined blackboard for English teaching comprises a chute 5, a pull rod 6, a slide block 7, a first blackboard eraser 10, a second blackboard eraser 11, a display area 15, a writing area 16 and a brush 18, wherein the left end of the right blackboard 1 is fixedly connected with a left blackboard 2, a blackboard eraser main body 3 is slidably connected between the right blackboard 1 and the left blackboard 2, the first blackboard eraser 10 uniformly penetrates through the blackboard eraser main body 3, the right end of the first blackboard eraser 10 is fixedly connected with a first push rod 12, the lower end of the first blackboard eraser 10 at the bottom is hinged with a bottom cover 14, the blackboard eraser main body 3 between the first blackboard eraser 10 is respectively penetrated with the second blackboard eraser 11, the left end of the second blackboard 11 is fixedly connected with a second push rod 13, the chute 5 is embedded into two ends of the right blackboard 1, a partition plate 8 is uniformly and fixedly connected inside the chute 5, the front surface of the right blackboard 1 is uniformly and fixedly connected with the display area 15, the right blackboard 1 at the lower, writing regional 16's dead ahead sliding connection has baffle 4, and the equal fixedly connected with slider 7 in one side that the spout 5 is close to at baffle 4 both ends, the equal fixedly connected with brush 18 of the last lower extreme of slider 7, the equal fixedly connected with lug 17 of the right-hand member of baffle 4, equal fixedly connected with pull rod 6 between the lug 17, the right blackboard 1 bottom that corresponds pull rod 6 lower extreme rotates and is connected with loading board 9.

The upper end and the lower end of the blackboard eraser main body 3 facing one side of the left blackboard and the lower end of the right blackboard are respectively provided with a sliding area, and the upper end and the lower end of the left blackboard and the lower end of the right blackboard are respectively provided with a sliding groove corresponding to the sliding areas, so that the blackboard eraser main body 3 can uniformly move in the sliding grooves without any obstruction when moving towards any end to erase, and the blackboard can be erased cleanly, conveniently and quickly.

The length and height of the baffle 4 are consistent with those of the display area 15 and the writing area 16, and the length and the height are consistent, so that English in the display area 15 can be blocked by the baffle 4 in the dictation process, and the dictation efficiency is higher.

Wherein, the length and the width of the first blackboard eraser 10 and the second blackboard eraser 11 are all consistent with the length and the width of the baffle 4, the display area 15 and the writing area 16, so that the baffle 4 can be just penetrated through for all-around wiping when the blackboard erasers are used for wiping, and the display area 15 and the writing area 16 can be wiped correspondingly and completely simultaneously, so that the wiping is convenient, fast and efficient.

The sliding blocks 7 at the two ends of the baffle 4 correspond to the sliding grooves 5 at the two ends of the right blackboard, so that the sliding blocks 7 at the two ends of the baffle 4 are driven to move up and down in the sliding grooves 5 when the pull rod 6 is pulled, and the blackboard is fast and convenient.

Wherein, the rear end of blackboard eraser 10 and No. two blackboard erasers 11 all sets up to hollow, set up to hollow dust that makes it drop when wiping can enter into inside and accomodate, make its dust can not fly upward at will, all the bottom of blackboard eraser 10 and No. two blackboard erasers 11 all is provided with bottom 14 simultaneously, be convenient for open it when setting up bottom 14 and take out the clearance to inside dust, and bottom 14 articulates and opens, the grafting is closed, it is all comparatively convenient to make it open and close.

Wherein, the length between the baffle 8 is unanimous with the width of display area 15, writing region 16 and baffle 4, just bears the weight of when making its baffle 4 move down and corresponds the placing on baffle 8, reaches the firm effect of baffle 4, and the quantity of baffle 8 all corresponds with the quantity of baffle 4, makes its mutual correspondence.

The working principle is as follows: firstly, the pull rod 6 can be pulled downwards when the teaching is needed, so that all the baffles 4 are driven to move downwards to cover the writing area 16, meanwhile, the display areas 15 are aligned, the slide blocks 7 at two ends slide downwards in the slide grooves 5 in the downward moving process of the baffles 4, the slide grooves are cleaned by brushes when the slides, and finally, the baffles are placed on the partition plates 8 to be stable, so that teachers can better perform the teaching corresponding to English in the teaching process, the teaching efficiency is improved conveniently, then, when the dictation or the dictation is needed, the pull rod 6 can be pushed upwards to drive all the baffles 4 to move upwards to cover the display areas 15, the slide blocks 7 at two ends of the baffles 4 move upwards in the slide grooves 5 in the upward pushing process, then, the bearing plate 9 is lifted to carry out the bearing of the pull rod 6, the stability of the baffles 4 is achieved, and the dictation and the baffles 4 can be performed, after dictation is finished, the pull rod 6 is pulled down to cover the writing area 16 to perform English comparison teaching of the baffle 4 and the display area 15, then the pull rod 6 is pushed upwards again, a teacher can write in the writing area 16 to perform writing teaching again, so that the blackboard eraser is convenient and effective, secondly, when the baffle 4 and the display area 15 are to be wiped, the second push rod 13 can be pulled to enable all second blackboards 11 to be protruded outwards, the whole blackboard eraser main body 3 can be moved towards the right end to achieve omnibearing wiping of the baffle 4 and the display area 15, when the writing area 16 and the baffle 4 are required to be wiped, the first push rod 12 can be pulled to drive all first blackboard erasers 10 to be protruded outwards, the whole blackboard eraser main body 3 can be moved towards the right end to achieve omnibearing wiping of the writing area 16 and the baffle 4, all dust can enter a hollow part at the rear end corresponding to the lower end in the wiping process, finally, the bottom cover 14 is opened to clean dust, and when the left blackboard needs to be wiped, the blackboard eraser main body 3 can be directly moved to the left without pulling any push rod.
