Description
Technical field
The utility model relates to educational aid technical fields, especially belong to a kind of suitable for sundries cleaning auxiliary blackboard
Slot.
Background technique
A large amount of dust is had at present in education of middle and primary schools still based on black board teaching, therefore after chalk-writing to fall.In order to
Convenient for the cleaning of dust, the blackboard slot of a spill is usually set in the lower end of blackboard, so that dust collection to blackboard slot be united
One cleaning, but since blackboard slot is " Kan " shape, so many dust are caught in dead angle, not easy cleaning.And present blackboard uses more
Push-and-pull blackboard with inserted multimedia whiteboards and chalkboards convolution, push-and-pull when in order to use for outside blackboard, both sides are black
The blackboard groove width one wide one in board bottom portion is narrow, in this way, tending to accumulate chalk dust in the blackboard slot of its bottom, if using water
When clearing up blackboard, the dirty water under clearing up also is difficult to pour out, and sometimes, the chalk end that falls, chalk section can also leave because erasing the board
Its bull pine is caused to waste by water.
Simultaneously as these dust accumulations easily cause dust pollution when blowing in blackboard slot, and it is widely present
Halfway phenomenon is cleared up, thus, the dust collection and cleaning plant of a kind of blackboard slot how are designed, is anticipated with important research
Justice.
Summary of the invention
The purpose of this utility model is to provide a kind of sundries cleaning auxiliary blackboard slot, to reach practical, cleaning
The good purpose of effect.
Sundries cleaning auxiliary blackboard slot provided by the utility model, which is characterized in that including being mounted on push-and-pull blackboard bottom
The blackboard slot in portion, blackboard slot include left groove and right groove, and left groove is coupled by shaft with right groove and is fixed to push-and-pull
On blackboard boundary frame area, the left groove, right groove outer end be respectively equipped with firm banking, have connection logical on firm banking
Hole pushes and pulls on the frame at left and right sides of blackboard, is respectively equipped with the fixation nose of concave structure corresponding with connection through-hole, left recessed
Slot, right groove are latched by L-type respectively, are connected and fixed with push-and-pull blackboard left and right side frame, wherein black with pushing and pulling for push-and-pull blackboard
The recess width of the blackboard slot of plate cooperation, less than the recess width of the blackboard slot of the fixation blackboard cooperation with push-and-pull blackboard, and it is left
The opposite front end of groove, right groove, respectively with the groove segment of a hollow out；The middle position of blackboard trench bottom is equipped with and connects box, connects
For box centered on shaft, the width for connecing box is corresponding with the bottom of groove segment of hollow out in left groove, right groove, connects the left and right of box
Both ends are connected and fixed with left groove, right groove respectively.
Further, the bottom of the opposite one end of above-mentioned left groove, right groove, is respectively equipped with sliding slot, connects box and passes through sliding slot,
It is connected and fixed with left groove, right groove.
Further, the end of longitudinal drooping section of above-mentioned L-type lock is arc.
Sundries cleaning auxiliary blackboard slot provided by the utility model, it is reasonable in design, it is practical, change tradition
The drawback that blackboard slot structure is single, cleaning is inconvenient, the utility model can be as needed, after blackboard slot to be lifted to certain height
Algebraic difference between adjacent gradients are formed, cooperates the use of cleaning device, using gravity, makes the dirty water cleared up, the chalk end of collection, chalk
Section etc., slides into connecing in box for blackboard trench bottom；The setting of blackboard trench bottom connect box and blackboard slot is connected and fixed by sliding slot, it is convenient
Dismounting, to make the more convenient to use, functional stronger of the utility model.In conclusion the utility model, which has, improves people
The good effect of propertyization design and protection environment.
Detailed description of the invention
Attached drawing part discloses the utility model specific embodiment, wherein
Fig. 1 is the front view of the utility model；
Fig. 2 is partial enlargement diagram at the utility model A；
Fig. 3 is the top view of the utility model.
Specific embodiment
As shown in Figure 1-3, sundries cleaning auxiliary blackboard slot provided by the utility model, including it is mounted on push-and-pull blackboard 1
Blackboard slot on boundary frame area.In the present embodiment, push-and-pull 1 left side of blackboard is fixed blackboard 11, and the right is pushing away of pushing and pulling to the left
Blackboard 12 is drawn, the inside that can push and pull blackboard is equipped with multimedia blank.Blackboard slot includes left groove 3 and right groove 4, left groove with
Right groove is coupled by shaft 5 and is fixed on push-and-pull blackboard boundary frame area.The outer end of the left groove, right groove is set respectively
There is a firm banking 6, there is connection through-hole 2 on firm banking, push and pull on the frame at left and right sides of blackboard, is respectively equipped with and leads to connecting
The fixation nose 7 of the corresponding concave structure in hole, left groove, right groove are respectively by L-type lock 8, with push-and-pull blackboard left and right side frame
It is connected and fixed, wherein the recess width with the blackboard slot for pushing and pulling blackboard cooperation of push-and-pull blackboard is consolidated less than with push-and-pull blackboard
The recess width of the blackboard slot of blackboard cooperation, and the front end that left groove, right groove are opposite are determined, respectively with the groove of a hollow out
Section, the i.e. left hollow out section 31, the right hollow out section 41 of the front end of right groove of the front end of left groove, the interposition of blackboard trench bottom
