Description
Technical field
Teaching equipment field is the utility model is related to, especially a kind of enclosed type blackboard eraser.
Background technology
During teachers, the letter written with chalk to write on the blackboard can be wiped using blackboard eraser mostly, but use blackboard eraser
Wiping chalk word can kick up substantial amounts of chalk dust, this phenomenon, can seriously damage the health of teacher in the past for a long time.It is and existing
Dust suppression type chalkboard eraser is required for transforming chalkboard eraser in itself greatly, and this cost for allowing for manufacturing chalkboard eraser increased.
Utility model content
In order to overcome the shortcomings of that existing blackboard eraser easily kicks up dust, the utility model provides a kind of enclosed type blackboard
Wipe.
Technical scheme is used by the utility model solves its technical problem：A kind of enclosed type blackboard eraser, including wiping board,
Arc cover body, closed-loop, thread barrel and outlet, the inwall intennediate bond of arc cover body are connected with thread barrel, opened on thread barrel
Mouth end is connected with the upper open end of arc cover body, and the lower end of thread barrel is provided with outlet, and the aperture of outlet is less than the straight of thread barrel
Footpath, wiping board are placed in and are fixedly connected in thread barrel, and closed-loop is fixedly connected on the under shed edge of arc cover body, arc-shaped cover
Body is transparent material.
According to another embodiment of the present utility model, further comprise that screw rod is threadedly coupled with thread barrel, wiping board is placed in
Between screw rod and outlet, the felt body portion of wiping board passes through outlet.
According to another embodiment of the present utility model, further comprise that screw rod upper end bonding connection has handle.
According to another embodiment of the present utility model, further comprise that the under shed edge of arc cover body is provided with card
Groove, neck have been embedded in closed-loop, in closed-loop adhesion have brush body.
According to another embodiment of the present utility model, further comprise the transparent acrylic material of arc-shaped cover position.
The beneficial effects of the utility model are that the utility model can be carried out at dust suppression using existing ordinary blackboard eraser
Reason, without additionally transforming blackboard eraser body, avoided former old blackboard eraser from leaving unused, time saving and energy saving, saved
Cost, and have good anti-dust effect.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is front view of the present utility model；
Fig. 2 is upward view of the present utility model；；
Fig. 3 is state diagram when the utility model does not install wiping board；
Fig. 4 is the structural representation of screw rod；
1. wiping board in figure, 2. arc cover bodies, 3. closed-loops, 4. thread barrels, 5. outlets, 6. screw rods, 7. handles,
8. neck, 9. brush bodies.
Embodiment
If Fig. 1 is front view of the present utility model, Fig. 2 is upward view of the present utility model, and Fig. 3 is that the utility model is not pacified
Fill wiping board when state diagram, Fig. 4 is the structural representation of screw rod, a kind of enclosed type blackboard eraser, including wiping board 1, arc cover body 2,
Closed-loop 3, thread barrel 4 and outlet 5, the inwall intennediate bond of arc cover body 2 is connected with thread barrel 4, the upper open end of thread barrel 4
It is connected with the upper open end of arc cover body 2, the lower end of thread barrel 4 is provided with outlet 5, and the aperture for exporting 5 is less than the straight of thread barrel 4
Footpath, wiping board 1 are placed in and are fixedly connected in thread barrel 4, and closed-loop 3 is fixedly connected on the under shed edge of arc cover body 2, arc
Shape cover body 2 is transparent material, and screw rod 6 is threadedly coupled with thread barrel 4, and wiping board 1 is placed between screw rod 6 and outlet 5, the hair of wiping board 1
Felt body portion is through exporting 5, and the upper end bonding connection of screw rod 6 has handle 7, and the under shed edge of arc cover body 2 is provided with neck 8,
Neck 8 has been embedded in closed-loop 3, in closed-loop 3 adhesion have brush body 9,2 transparent acrylic materials of arc cover body.
When to be installed and used, screw rod 6 is first turned on so that the opening that arc cover body 2 connects with thread barrel 4 is exposed
（As shown in Figure 3）, then wiping board 1 is put at the openend of arc cover body 2, such wiping board 1 will fall to thread barrel 4
Cylinder bottom.And due to thread barrel 4 diameter be more than wiping board 1 length, export 5 diameter be less than wiping board 1 length, so wiping board
1 is able to be retained in without going out to drop out from outlet 5 in thread barrel 4, but the felt body portion of this thing wiping board 1 is to expose outlet 5
's.Screw rod 6 is to cooperate with thread barrel 4, finally holds the handle 7 of screw rod 6, screw rod 6 is screwed into thread barrel 4
It is interior, until the back of wiping board 1 is withstood on the top of screw rod 6（As shown in Figure 1）, it is achieved thereby that wiping board 1 and arc cover body 2 are consolidated
Fixed connection.
In use, hold handle 7, drive the wiping board 1 of its bottom toward smearing on blackboard, can with erasing chalk word, due to
When wiping board 1 smears blackboard, the brush body 9 in its closed-loop 3 is also fitted with blackboard, and one can be so formed among movement
The space of closing so that dust can not wave.And brush body 9 can not only suppress the excessive of dust, big portion can also be adsorbed
The dust divided.It is in order to which user can be allowed to be observed through arc cover body 2 using transparent acrylic material as arc cover body 2
Wiping board 1 position internal to it, sight obstruction when avoiding carrying out selective erase, and acrylic material structural strength
Height, it is in light weight, it is user-friendly without causing hand tired too early.
The utility model can carry out dust suppression processing using existing ordinary blackboard eraser, without additionally to blackboard eraser
Body is transformed, and avoids former old blackboard eraser from leaving unused, time saving and energy saving, has saved cost, and has good dust suppression to imitate
Fruit.
