Problems solved by technology

The current blackboard eraser and the blackboard are two separate parts. After the blackboard eraser is used, the blackboard will be placed on other carriers. Because most of the places where the blackboard eraser is used are schools, students are likely to lose the blackboard eraser when they are playing. , leading to the time-consuming and laborious search for the next time you use the blackboard eraser
[0003] At the same time, when the current blackboard eraser erases chalk writing, a large amount of dust will splash out, causing dust to adhere to the body of the wiper and the nearby air. A large number of dust particles, excessive dust adsorption in the body will cause great harm, so the current blackboard eraser has many disadvantages when it is used

Embodiment 1

[0044] see Figure 1-Figure 5 As shown, the purpose of this embodiment is to provide an adsorption type dust suppression type blackboard eraser, comprising a blackboard body 100, and the blackboard body 100 at least includes:

[0045] Fixed plate 1001, fixed plate 1001 is installed on the end of blackboard body 100, and the surface of fixed plate 1001 is provided with chute 10012, and the inside of chute 10012 is provided with several groups of positioning springs 10013, and one end of locating spring 10013 is installed with fixed block 10014 , the fixed block 10014 is fixedly connected with the chute 10012, the other end of the positioning spring 10013 is provided with a stopper 10015, and the stopper 10015 is slidably connected with the chute 10012, and the surface close to the chute 10012 is provided with a slide cavity 10011, and the slide cavity 10011 A slide plate 111 is slidingly connected inside, and a shaft is provided on one side of the bottom of the slide plate 111,...

Embodiment 2

[0051] In order to facilitate personnel to move the position of the blackboard eraser body 112, the difference between this embodiment and Embodiment 1 is that please refer to Figure 6 and Figure 7 Shown:

[0052] The surface of the fixed plate 1001 is provided with a mounting block 116, the surface of the mounting block 116 is equipped with a connecting spring 1161, and one end of the connecting spring 1161 is fixedly installed on the surface of the slide plate 111, the side of the slide plate 111 is connected with a rope body 1162, and the side of the blackboard body 100 A mounting frame 1164 is provided, and a shaft ring 1165 is installed on the surface of the mounting frame 1164. The shaft ring 1165 is fixedly connected with the rope body 1162. The other end of the shaft ring 1165 is equipped with a shaft disc 1166. When the shaft disc 1166 rotates, the shaft ring 1165 Rotate, the shaft ring 1165 rotates and wraps around the rope body 1162, and the rope body 1162 is pul...

Embodiment 3

[0056] In order to make the blackboard eraser body 112 further assist the teaching, the difference between this embodiment and Embodiment 1 is that please refer to Figure 8-Figure 10 Shown:

[0057] The side of blackboard eraser body 112 is provided with slide rail 1122, and the inside of slide rail 1122 is slidingly connected with slide block 117, and the surface of slide block 117 is provided with fixed cavity 1171, and fixed spring 1172 is installed in the inside of fixed cavity 1171, and the fixed cavity 1171 There is a chalk body 1173 plugged inside, which cannot satisfy the use of teaching tools for schools in poor mountainous areas. When teaching drawing on the surface of the blackboard body 100, for example: when drawing a circle or arc, the teacher cannot Accurately draw a circle, the chalk can be inserted into the fixed cavity 1171, the blackboard eraser body 112 rotates, that is, the blackboard eraser body 112 drives the slider 117 to rotate in an arc, the chalk bo...

Abstract

The invention relates to the technical field of blackboard erasers, in particular to an adsorption type raise dust suppression blackboard eraser. The adsorption type raise dust suppression blackboard eraser comprises a blackboard body and a water storage tank, the blackboard body at least comprises a fixing plate, a sliding groove is formed in the surface of the fixing plate, a plurality of sets of positioning springs are arranged in the sliding groove, a fixing block is installed at one end of each positioning spring and fixedly connected with the sliding groove, and a blocking piece is arranged at the other end of each positioning spring and slidably connected with the sliding groove; a sliding cavity is formed in the surface close to the sliding groove, a sliding plate is slidably connected into the sliding cavity, a shaft rod is arranged on one side of the bottom of the sliding plate, and a blackboard eraser body is connected to the surface of the shaft rod; and the bottom of the water storage tank is connected with a drainage pipe, the surface of the sliding groove is provided with a connecting opening, and the drainage pipe is fixedly connected with the connecting opening. When the blackboard eraser body rotates to a certain degree, the blocking piece can be pushed away, water flows downwards, dust generated in the wiping process is humidified to form particles, and splashing is prevented.

Description

technical field [0001] The invention relates to the technical field of blackboard erasers, in particular to an adsorption-type dust-suppressing blackboard eraser. Background technique [0002] A blackboard eraser is a device used to erase chalk writing on a blackboard. The current blackboard eraser and the blackboard are two separate parts. After the blackboard eraser is used, the blackboard will be placed on other carriers. Because most of the places where the blackboard eraser is used are schools, students are likely to lose the blackboard eraser when they are playing. , leading to time-consuming and laborious searching when using the blackboard eraser next time. [0003] At the same time, when the current blackboard eraser erases chalk writing, a large amount of dust will splash out, causing dust to adhere to the body of the wiper and the nearby air. A large amount of dust particles, excessive dust absorption in the body will cause great harm, so the current blackboard ...
