Abstract
The utility model discloses an electric remote control blackboard eraser which comprises a moving frame, an installation frame, a front wheel, a rear wheel, a driving mechanism, a remote control device and a blackboard eraser body. The moving frame slides along the edge of a blackboard, the installation frame is fixedly arranged on the moving frame, the front wheel is arranged at the front end of the installation frame in a rotation mode, the rear wheel is arranged at the rear end of the installation frame in a rotation mode, the driving mechanism drives the front wheel or the rear wheel to rotate, the remote control device is electrically connected with the driving mechanism, and the blackboard eraser body is detachably connected with the moving frame. The front wheel, the rear wheel and the surface of the blackboard are tightly attached mutually. An eraser is installed on the moving frame, the driving mechanism is driven by the remote control device, and the driving mechanism drives the front wheel or rear wheel to rotate and then the moving frame slides along the length direction of the blackboard. The blackboard is cleaned by the eraser, and after clearing, the eraser is stopped by the remote control device. Operation is convenient and the structure is simple.
Description
Technical field
The utility model relates to a kind of electric remote control blackboard eraser.
Background technology
In school, teacher every day on class all will be on blackboard the writing on the blackboard content, write not and will wipe with blackboard eraser, all be by manually operating at present, in blackboard eraser nuzzled up journey, the chalk foam flew upward, harm teacher's health.And taken the time of giving a lesson, show according to the relevant report statistics data of country: the annual about 200g/ people of chalk dust because sucking on class of the teachers and students of China, about 20%/year of trouble respiratory tract, PUD D, cancer.This shows that chalk dust is very large to teachers and students' health hazard.The chalk dust that flies upward simultaneously pollutes very large to teachers and students' personal hygiene, as the chalk dust that flies upward makes teachers and students' collar, cuff, hair, that annoying shade that all be unable to do without it with it.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of electric remote control blackboard eraser is provided, and is simple in structure, can the far distance controlled automatic blackboard cleaning, and easy to operate, reduce chalk dust to the injury of human body.
For achieving the above object, the technical solution of the utility model has provided a kind of electric remote control blackboard eraser, comprise the movable stand that slides along the blackboard edge, be fixedly installed on the installing rack on the described movable stand, rotation is arranged at the front-wheel of described installing rack leading section, rotation is arranged at the trailing wheel of described installing rack rearward end, drive the driving mechanism that described front-wheel or described trailing wheel rotate, the remote control equipment that is electrically connected mutually with described driving mechanism, dismantle mutually the blackboard eraser body that is connected, described front-wheel with described movable stand, described trailing wheel is close to mutually with described blackboard surface.
As preferably, described remote control equipment is infrared remote control equipment.
As preferably, the front side of described movable stand is fixedly installed the magnet that is useful on the adsorbing blackboard eraser body.
As preferably, the both sides of described movable stand are fixedly connected with side plate, rotate on the described side plate and are provided with roller, and described roller rolls along described blackboard both sides of the edge.
As preferably, the both sides of described blackboard offer guide-track groove, and described roller rolls and is arranged in the described guide-track groove.
As preferably, be provided with sponge between described movable stand and the described blackboard.
As preferably, the size of described front-wheel is less than the size of described trailing wheel.
Advantage of the present utility model and beneficial effect are: blackboard eraser is installed on the movable stand, start driving mechanism by remote control equipment, driving mechanism drives front-wheel or trailing wheel rotates, then movable stand slides along the length direction of blackboard, blackboard eraser is cleared up blackboard, after cleaning out, stops by remote control equipment, easy to operate, simple in structure.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Among the figure: 1, movable stand; 2, installing rack; 3, front-wheel; 4, trailing wheel; 5, driving mechanism; 6, remote control equipment; 7, blackboard eraser body; 8, magnet; 9, side plate; 10, roller.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of electric remote control blackboard eraser, the remote control equipment 6 that comprises the movable stand 1 that slides along the blackboard edge, is fixedly installed on installing rack 2 on the described movable stand 1, rotates the front-wheel 3 that is arranged at described installing rack 2 leading sections, rotates the trailing wheel 4 that is arranged at described installing rack 2 rearward end, drives driving mechanism 5 that described front-wheel 3 rotates, is electrically connected mutually with described driving mechanism 5, dismantle mutually the blackboard eraser body 7 that is connected with described movable stand 1, described front-wheel 3, described trailing wheel 4 are close to mutually with described blackboard surface.
As shown in Figure 1, described remote control equipment 6 is infrared remote control equipment 6.
As shown in Figure 1, the front side of described movable stand 1 is fixedly installed the magnet 8 that is useful on adsorbing blackboard eraser body 7.Can regulate at any time according to required cleaning place the position of blackboard eraser.
As shown in Figure 1, the both sides of described movable stand 1 are fixedly connected with side plate 9, rotate on the described side plate 9 and are provided with roller 10, and described roller 10 rolls along described blackboard both sides of the edge.The power of reducing friction.
Without diagram, the both sides of described blackboard offer guide-track groove, and described roller 10 rolls and is arranged in the described guide-track groove.
Without diagram, be provided with sponge between described movable stand 1 and the described blackboard.Avoid movable stand 1 to damage blackboard.
As shown in Figure 1, the size of described front-wheel 3 is less than the size of described trailing wheel 4.
Operation principle: blackboard eraser is adsorbed on the magnet 8 of movable stand 1, start driving mechanism 5 by remote control equipment 6, driving mechanism 5 drives front-wheel 3 and rotates, then movable stand 1 slides along the length direction of blackboard, blackboard eraser is cleared up blackboard, after cleaning out, stops by remote control equipment 6, easy to operate, simple in structure.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
