Description

A kind of English-teaching aid

Technical field

The utility model belongs to teaching equipment field, and in particular to a kind of English-teaching aid.

Background technology

In English teaching, blackboard writing on the blackboard is be unable to do without, during writing on the blackboard, for the writing of specification English alphabet, often Need to draw the equidistant straight line in four roads with ruler on blackboard, and the time of classroom instruction is limited, it is necessary to when spending many Between, meanwhile, also often there is the problem of line distance is not waited, cause writing lack of standardization.

Utility model content

The purpose of this utility model is to provide a kind of English-teaching aid, with asking for solving to propose in above-mentioned background technology Topic.

To achieve the above object, the utility model provides following technical scheme：A kind of English-teaching aid, including framework, The framework lower end is fixedly connected with sucker, and the framework upper end is connected with bracket slide, and the support is fixed with scriber to be connected Connect, the framework both sides are provided with fixing hole, the frame left is fixedly connected with left handrail, the frame right is consolidated with right handrail Fixed connection.

It is preferred that, the support includes main body, and the main body two ends are fixedly connected with longitudinal sliding block, on the longitudinal sliding block Provided with spring, the spring upper end is fixedly connected with fixed column, and the body interior is provided with horizontal concrete chute.

It is preferred that, the scriber includes line block, and the line block upper end is fixedly connected with push rod, the line block two End is fixedly connected with transverse slider, and the line block lower end is provided with chalk hole, and the chalk hole is provided with chalk.

It is preferred that, the fixing hole is set to 6.

It is preferred that, the chalk hole is set to 4.

Technique effect of the present utility model and advantage：The English-teaching aid, can once property draws four on blackboard The lattice of line three, improve setting-out speed, and alleviate the work of teacher, and the device firmly can be fixed on blackboard by sucker, The stability of device is improved, by the cooperation of fixing hole and fixed column, a position is secured the stand to, prevents in setting-out Journey medium-height trestle shifts, it is ensured that setting-out quality, left handrail and right handrail provide fulcrum firmly to user, by device Be moved to the position of needs, by the cooperation of spring and fixed column, fixed column can be ensconced when bracket slide it is following, Encountering fixing hole can eject again.

In figure：1 framework, 2 suckers, 3 supports, 301 main bodys, 302 longitudinal sliding blocks, 303 springs, 304 fixed columns, 305 are laterally Chute, 4 fixing holes, 5 scribers, 501 line blocks, 502 push rods, 503 transverse sliders, 504 chalk holes, 505 chalks, 6 left handrails, 7 right handrails.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

The utility model is provided under a kind of English-teaching aid as Figure 1-Figure 4, including framework 1, the framework 1 End is fixedly connected with sucker 2, and the upper end of framework 1 is slidably connected with support 3, and the support 3 is fixedly connected with scriber 5, institute The both sides of framework 1 are stated provided with fixing hole 4, the left side of framework 1 is fixedly connected with left handrail 6, the right side of framework 1 and right handrail 7 It is fixedly connected.

Further, the support 3 includes main body 301, and the two ends of main body 301 are fixedly connected with longitudinal sliding block 302, institute Longitudinal sliding block 302 is stated provided with spring 303, the upper end of spring 303 is fixedly connected with fixed column 304, inside the main body 301 Provided with horizontal concrete chute 305.

Further, the scriber 5 includes line block 501, and the line upper end of block 501 is fixedly connected with push rod 502, The line two ends of block 501 are fixedly connected with transverse slider 503, and line block 501 lower end is provided with chalk hole 504, the powder Hole 504 is provided with chalk 505.

Further, the fixing hole 4 is set to 6.

Further, the chalk hole 504 is set to 4.

Operation principle：During work, user, which catches left handrail 6 and right handrail 7 that device is moved on blackboard, needs setting-out Position, device is then fixed on by required position by sucker 2, then catch push rod 502 by scriber 5 shift onto right side, draw Line device 5 is moved by transverse slider 503 in horizontal line chute 305, and setting-out is carried out on blackboard by chalk 505, treats this line After the lattice of four line three are painted, the fixed column 304 on both sides is pinned, fixed column 301 is following by being hidden in for spring 303, at this moment can To move down support 3, just eject and when fixed column 301 encounters fixing hole 4, again fix support 3, at this moment just can be again Secondary setting-out.
