Abstract
The invention relates to water scrubbing devices for a washing type strip-shaped blackboard. The water scrubbing devices are arranged at two sides of a blackboard frame and are used for cleaning the strip-shaped blackboard on the blackboard frame; each water scrubbing device comprises a water storage cavity close to the strip-shaped blackboard; a water outlet hole and scrubbing cloth are arranged at one side, close to the strip-shaped blackboard, on each water storage cavity; a supporting rod is hinged to the upper and lower ends of one side of each water storage cavity and is fixedly connected with the blackboard frame through fixing rods; a push rod is arranged on each supporting rod by means of a shaft sleeve in a front-back sliding manner; a cantilever bar is fixedly arranged at one side, away from the blackboard frame, on each supporting rod; a swing rod is hinged to the end part of each cantilever bar; the end part of each swing rod is adjacent to the side face of each water storage cavity; a sliding chute is formed in the other end of each swing rod; the inner end of each push rod is arranged in the corresponding sliding chute in a sliding manner; a spring seat is fixedly arranged on each push rod; a guiding L-shaped frame of the push rod is arranged on the blackboard frame; and a compression spring sleeves the push rod between each spring seat and the corresponding L-shaped frame.
Description
Technical field
The present invention relates to teaching aid, particularly to the cleaning device of blackboard.
Background technology
Existing blackboard is generally fixed on wall or the plate utilizing fixed support to prop up.Due to the limited width in classroom, limit
Having made the width of blackboard, when writing full picture and text, needed erasing above, the position that leaves some space could continue to write.During erasing
There is the phenomenon that dust flies upward, and waste certain instructional blocks of time.Existing blackboard, when needs water rinses, Zhi Nengyong
Clean after rag immersion, there is certain inconvenience.
Summary of the invention
In consideration of it, existing blackboard is studied and is designed by applicant, it is provided that one can extend use width, take up room little,
Save the scrub water device of the rinsing type banding blackboard of erasing time, raising teaching efficiency.
In order to solve the problems referred to above, the present invention uses following scheme:
The scrub water device of a kind of rinsing type banding blackboard, this scrub water device is installed on the both sides of easel, is used for cleaning blackboard
Banding blackboard on frame, including the water storage cavity near described banding blackboard, on water storage cavity, the side near banding blackboard is provided with water outlet
Hole is also installed on scrubbing cloth, and the upper and lower two ends, side of water storage cavity are hinged with support bar, and described support bar is by fixing bar and easel
Fixing connection, support bar is provided with push rod by axle sleeve slide anteroposterior, away from the fixing peace in side of described easel on support bar
Equipped with cantilever lever, the end of described cantilever lever is hinged with swing arm, the side of the end of described swing arm and described water storage cavity against,
The other end of swing arm has chute, and the inner of described push rod is slidably mounted in described chute；Described push rod is installed with bullet
Spring abutment, easel is provided with the guiding L-type frame of push rod, the push rod between described spring base and L-type frame is equipped with stage clip.
The method have technical effect that:
The scrub water device that the present invention uses, when blackboard cleans, only need to start water pump, to utilize push rod that water storage cavity is pushed down banding black
Plate, simple to operate, easy to clean, during cleaning, water will not splash, it is ensured that clean and tidy environment during cleaning.

Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As shown in Figure 1 and Figure 2, the scrub water device of the rinsing type banding blackboard of the present embodiment, this scrub water device is installed on black
The both sides of grillage 1, for cleaning the banding blackboard 2 on easel 1, including the water storage cavity 8 near banding blackboard 2, water storage cavity
On 8, the side near banding blackboard 2 is provided with apopore 81 and is installed on scrubbing cloth 9, and the upper and lower two ends, side of water storage cavity 8 are hinged
Having support bar 10, support bar 10 is connected by fixing bar 11 and easel 1 is fixing, on support bar 10 by axle sleeve 12 before and after
Being slidably fitted with push rod 13, on support bar 10, the side away from easel 1 is installed with cantilever lever 14, the end of cantilever lever 14
Portion is hinged with swing arm 15, the side of the end of swing arm 15 and water storage cavity 8 against, the other end of swing arm 15 has chute
16, the inner of push rod 13 is slidably mounted in chute 16；Push rod 13 is installed with spring base 17, and easel 1 is installed
There is the guiding L-type frame 19 of push rod 13, the push rod 13 between spring base 17 and L-type frame 19 is equipped with stage clip 18.
When needs carry out water cleaning to banding blackboard 2, start water pump and be passed through clear water in water storage cavity 8, start banding black simultaneously
The driving motor 6 of plate 2, banding blackboard 2 slides on easel 1, by inwardly promoting push rod 13, the inner extruding of push rod 13
Swing arm 15, swing arm 15 extrudes water storage cavity 8, and the scrubbing cloth 9 of water storage cavity 8 side contacts with banding blackboard 2, thus to band
Shape blackboard 2 surface clean, the water after cleaning flows in the wastewater disposal basin (being not drawn in figure) below easel 1.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not appoints the present invention
What pro forma restriction, has usually intellectual, if without departing from the carried technical characteristic of the present invention in any art
In the range of, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from this
Bright technical characteristic content, all still falls within the range of the technology of the present invention feature.
