Description
Technical field
The utility model relates to a kind of Multifunctional blackboard groove, belongs to realia technical field of structures.
Background technology
Blackboard is one of requisite educational aid of teachers ' teaching, after teacher uses chalk to carry out writing on the blackboard on blackboard, a large amount of chalk powder can be gathered in blackboard slot, owing to being placed with chalk in blackboard slot, therefore during clean blackboard slot, need first the chalk in blackboard slot to be picked, and then blackboard slot is cleaned, very inconvenient, moreover, existing blackboard slot structural design is single, only has the effect of splendid attire chalk and access chalk powder, then without other effect.
Summary of the invention
The purpose of this utility model is the weak point solving prior art existence, provides a kind of reasonable in design, can clean the chalk powder in ledge for chalk on blackboard quickly and easily, and can be used as the Multifunctional blackboard groove of showing that hanger uses.
The utility model is achieved through the following technical solutions:
A kind of Multifunctional blackboard groove, its special character is to comprise blackboard slot body 1, the upper surface of blackboard slot body 1 is provided with rectangular block 2, bearing 3 is provided with in block 2, bearing 3 comprises two upright arms 5 separately, between two upright arms 5, rotating shaft 4 is installed, rotating shaft 4 is provided with can around the shaft 4 rotate hollow pipes 6, the section of hollow pipe 6 is rectangular, the upper surface length direction of hollow pipe 6 is provided with strip opening, strip opening part is provided with can the door body 7 of switch, multiple baffle plate 13 is separately provided with in hollow pipe 6, the outer cover of hollow pipe 6 is provided with the collar 14 that can rotate along its outer wall, the collar 14 is provided with cylindricality coil 8, the inside of cylindricality coil 8 is provided with internal thread, a wherein sidewall of hollow pipe 6 is also provided with two snap rings 9 separately, column 10 is plugged with in snap ring 9, column 10 is provided with multiple clip 15 separately, one end of column 10 be provided with coil 8 with the use of column-shaped projection 11, the outer surface of column-shaped projection 11 is provided with external screw thread,
Described block 2 comprises a vertical elevation 12 and two sidewalls 16 be connected with vertical elevation 12, and the height of vertical elevation 12 is higher than upright arm 5;
A kind of Multifunctional blackboard groove of the present utility model, structural design is very ingenious, the scattered chalk being placed in blackboard slot at ordinary times can be positioned in hollow pipe, when the clean blackboard slot of needs, only need close a body, on lift hollow pipe, then burnisher is used to clean blackboard slot, eliminate and pick up this step of chalk from blackboard slot, and hollow pipe can protect chalk, and can prevent because the loss caused arbitrarily put by chalk, in addition, the utility model can also use as hanger, hollow pipe is lifted on only needing, then column is rotatably connected on coil, a support can be formed, then will the wall chart shown be needed to be clamped by clip, very easy to use.In sum, the utility model reasonable in design, easy to use, there is good application prospect.
Accompanying drawing explanation
Fig. 1: the structural representation of a kind of Multifunctional blackboard groove of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
A kind of Multifunctional blackboard groove of the present embodiment, comprise blackboard slot body 1, the upper surface of blackboard slot body 1 is provided with rectangular block 2, bearing 3 is provided with in block 2, bearing 3 comprises two upright arms 5 separately, between two upright arms 5, rotating shaft 4 is installed, rotating shaft 4 is provided with can around the shaft 4 rotate hollow pipes 6, the section of hollow pipe 6 is rectangular, the upper surface length direction of hollow pipe 6 is provided with strip opening, strip opening part is provided with can the door body 7 of switch, multiple baffle plate 13 is separately provided with in hollow pipe 6, the outer cover of hollow pipe 6 is provided with the collar 14 that can rotate along its outer wall, the collar 14 is provided with cylindricality coil 8, the inside of cylindricality coil 8 is provided with internal thread, a wherein sidewall of hollow pipe 6 is also provided with two snap rings 9 separately, column 10 is plugged with in snap ring 9, column 10 is provided with multiple clip 15 separately, one end of column 10 be provided with coil 8 with the use of column-shaped projection 11, the outer surface of column-shaped projection 11 is provided with external screw thread, block 2 comprises a vertical elevation 12 and two sidewalls 16 be connected with vertical elevation 12, and the height of vertical elevation 12 is higher than upright arm 5.
Using method: hollow pipe 6 is for the chalk of splendid attire every day use, namely the chalk of every day use is not directly be positioned in blackboard slot after using, but be positioned in hollow pipe 6, when the clean blackboard slot of needs, only need close a body 7, on lift hollow pipe 6, then burnisher is used to clean blackboard slot, eliminate and pick up this step of chalk from blackboard slot, and hollow pipe 6 can protect chalk, and can prevent because the loss caused arbitrarily put by chalk, in addition, the utility model can also use as hanger, hollow pipe 6 is lifted on only needing, then column 10 is rotatably connected on coil 8, a support can be formed, then will the wall chart shown be needed to be clamped by clip 15.
