Description
Technical field
The utility model belongs to blackboard cleaning device field, and particularly one singly draws blackboard remaining trace scavenge unit.
Background technology
Blackboard is nowadays widely used, and its shape access node structure also becomes diversity more, but in working and learning, using maximum is then the mutual slip of two pieces of blackboards, it can be upper and lower relative sliding, also can be the relative sliding of left and right, but due to the volume of blackboard and quantity become more greatly, more more and more, the worried thing of people is also become gradually for the clean of blackboard.
Although people carried out two-way cleaning to also once attempting to the blackboard of two pieces of relative slidings, the installation for blackboard brush was but the bottleneck of this design, namely utilized the relative sliding of blackboard self to realize cleaning two pieces of blackboards simultaneously.
Utility model content
The purpose of this utility model is to provide one and singly draws blackboard remaining trace scavenge unit, this device can utilize the blackboard of relative sliding to realize the effect of singly drawing and once can clean two pieces of blackboards, in working and learning, greatly save the time erased the board, improve the efficiency of working and learning.
In order to reach above object, the technical solution adopted in the utility model is: one singly draws blackboard remaining trace scavenge unit, it is characterized in that, this device comprises left blackboard brush (1), right blackboard brush (3), upper rail (5), lower guideway (6), fixed connecting rod (8); Described upper rail (5) and lower guideway (6) are symmetrically arranged with right blackboard guide rail (12), have for the through hole (10) of fixed connecting rod (8) with right blackboard (4) movement in the middle of right blackboard guide rail (12); Described left blackboard brush (1) is arranged on the front panel of right blackboard (4) left end by fixed connecting rod (8), the distance between left blackboard brush (1) with right blackboard (4) is identical with the width h of left blackboard (2) with right blackboard brush (3); Described right blackboard brush (3) is arranged on the rear board of left blackboard (2) right-hand member, and the width d of the distance between left blackboard (2) with right blackboard (4) and right blackboard brush (3) is identical.
Described left blackboard brush (1) up and down two ends is provided with the detachable fixed lobe (9) for being installed on fixed connecting rod (8).
Described right blackboard brush (3) upper and lower end is symmetrically arranged with the detachable clip (7) for fixing left blackboard (2).
The beneficial effects of the utility model are: (1) the utility model structure is simple, designs ingenious, the blackboard that singly draws once can be used to move, realize the effect that two pieces of blackboards clean simultaneously, not only reduce the time erased the board, also improve the efficiency of working and learning.
(2) blackboard brush of the present utility model is provided with fixed lobe and clip, the connection of they and blackboard is detachable, and convenient to disassembly, and fully takes into account the diversity of use, can selective clean left and right blackboard.
