Abstract
The utility model discloses a novel multifunctional mathematical teaching blackboard which comprises a blackboard body. The upper end of the blackboard body is provided with a rail, one end of the rail is provided with a hydraulic cylinder, a sliding block is embedded in the rail, a piston rod of the hydraulic cylinder is connected with the sliding block, and the sliding block can slide along the rail under the action of the hydraulic cylinder; the sliding block is further hinged to a telescopic rod, the lower end of the telescopic rod is hinged to a supporting frame, the upper end of the supporting frame is provided with a book clamp, and the lower end of the supporting frame is provided with a supporting plate. The novel multifunctional mathematical teaching blackboard is simple in structure and convenient to use, a book can be placed on the supporting frame, and a teacher can draw while looking at the book, so that labor is saved and teaching efficiency is improved. Besides, by means of arrangement of the hydraulic cylinder and a wireless remote controller, the position of the supporting frame is automatically adjusted to be suitable for all positions of the blackboard, and a blackboard eraser is ingeniously combined with the supporting frame. Moreover, a spring is combined with a screw, so that the blackboard can be truly cleaned when the blackboard eraser is used.
Description
Technical field
The utility model relates to a kind of teaching equipment, specifically a kind of Multifunction mathematical education blackboard.
Background technology
In explanation during mathematical material, often having a large amount of mathematical formulaes, exercise question, legend need to write or draw on blackboard.At present, teacher is that another personal letter of hand-held book is write, and when running into need to draw time, also needs hand-held drawing instrument, therefore, to teaching, brings very big inconvenience.When erasing the board in teaching process in addition, be all manually to erase the board conventionally, very inconvenient, although also there is the instrument erasing the board of a lot of automations, conventionally all wipe unclean blackboard; And night in the class, light-illuminating is on blackboard, the student of some angles may can't see the content on blackboard.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and a kind of Multifunction mathematical education blackboard is provided.
The purpose of this utility model is the deficiency existing for prior art, a kind of Multifunction mathematical education blackboard is provided, comprise blackboard body, the upper end of described blackboard body is provided with track, one end of this track is provided with hydraulic cylinder, and track is embedded with slide block, the piston rod of described hydraulic cylinder is connected with slide block, and slide block can slide along track under the effect of hydraulic cylinder; On described slide block, be also hinged with an expansion link, the lower end of this expansion link is hinged with a bracket, and the upper end of described bracket is provided with book clamp, and lower end is provided with supporting plate; Described bracket is also connected with a blackboard eraser by three equally distributed springs, is also provided with screw on described bracket, be inserted with screw rod, and the head of this screw rod withstands on blackboard eraser in screw.
This practical utility model is in teaching process, books can be placed on bracket, while drawing, read a book, save muscle power, improve efficiency of teaching, and the utility model arranges hydraulic cylinder and Digiplex is realized automatically working, and cleverly blackboard eraser is attached on bracket, also can be used for erasing the board, very convenient.
As preferably, also comprise Digiplex, a side of described blackboard body is also provided with the control panel of hydraulic cylinder, is also provided with the wireless receiver being used in conjunction with Digiplex in this control panel.The utility model arranges Digiplex, can send a signal to the movement that wireless receiver is controlled hydraulic cylinder, thus position that can movable support bracket, thus make teacher writing while copying writing on the blackboard, very convenient.
As preferably, the below of described blackboard eraser is also provided with interchangeable disposable plastic bag.Polybag can connect the chalk bits that lower blackboard eraser stays, and can replace.
As preferably, three sides of described blackboard body are also provided with illuminating lamp and power supply.Illuminating lamp can be gone up at night and make the student of all angles can clearly see blackboard class hour.
As preferably, described screw rod is provided with two altogether.Two screw rods are set and more can guarantee stability.
As preferably, the top of described track is also provided with the rectangle accommodation box of bracket.When bracket is obsolete, can bracket be put in rectangle accommodation box by rotation, save trouble very much.
Beneficial effect: of the present utility model simple in structure, easy to use, books can be placed on bracket, while draw, read a book, save muscle power, improve efficiency of teaching, and the position that hydraulic cylinder and Digiplex are realized automation bracket is set, can adapts to each position of blackboard, and cleverly blackboard eraser is attached on bracket, and be provided with the combination of spring and screw rod, what make that blackboard eraser can be real in work is clean by blackboard eraser.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of bracket in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented take technical solutions of the utility model under prerequisite, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
As depicted in figs. 1 and 2, a kind of Multifunction mathematical education blackboard, comprise blackboard body 1, the upper end of described blackboard body 1 is provided with track 2, one end of this track 2 is provided with hydraulic cylinder 3, and track 2 is embedded with slide block 4, the piston rod of described hydraulic cylinder 3 is connected with slide block 4, and slide block 4 can slide along track 2 under the effect of hydraulic cylinder 3; On described slide block 4, be also hinged with an expansion link 5, the lower end of this expansion link 5 is hinged with a bracket 6, and the upper end of described bracket 6 is provided with book clamp 7, and lower end is provided with supporting plate 8; Described bracket 6 is also connected with a blackboard eraser 10 by three equally distributed springs 9, on described bracket 6, is also provided with screw, be inserted with screw rod 11, and the head of this screw rod 11 withstands on blackboard eraser 10 in screw.
Wherein, also comprise Digiplex, a side of described blackboard body 1 is also provided with the control panel 31 of hydraulic cylinder 3, in this control panel 31, is also provided with the wireless receiver being used in conjunction with Digiplex.
Wherein, the below of described blackboard eraser 10 is also provided with interchangeable disposable plastic bag 12.
Wherein, three of described blackboard body 1 sides are also provided with illuminating lamp 13 and power supply 14.
Wherein, described screw rod 11 is provided with two altogether.
Wherein, the top of described track 2 is also provided with the rectangle accommodation box 15 of bracket 6.
The utility model in use, can first books to be copied and drawing content be clipped on bracket with book clamp, expansion link can bracket height, because bracket and expansion link are hinged, bracket can rotate, and teacher can hold Digiplex by a hand, a hand is at the book of folding arms, and control hydraulic cylinder by Digiplex, thus control the position of bracket, very convenient.When needs are used blackboard eraser, the position of first adjusting screw(rod), blackboard eraser can be tightly attached on blackboard, then the position of controlling the piston rod of hydraulic cylinder both can erase the board, again because expansion link and slide block are hinged, blackboard eraser also can move in a circle around slide block, has improved the speed erasing the board.After finishing using, only need the position of adjusting screw(rod), spring retracts blackboard eraser.
