Abstract
A blackboard used for teaching comprises a rectangular board and borders, wherein the borders include two long borders and two short borders, long clamping grooves used for clamping the rectangular board are formed in the two long borders respectively, the two long borders are fixed on a wall, the length of each long border is equal to the length of each long side of the rectangular board, the two long sides of the rectangular board are clamped in the long clamping grooves in the two long borders, the rectangular board is installed between the two long borders, short clamping grooves are formed in the two short borders respectively, the two ends of each long border and the two short sides of the rectangular board are all clamped in the short clamping grooves in the two short borders, corresponding positioning threaded holes are formed in the short borders, in the two ends of each short border and in the four corners of the rectangular board, and the short borders, the rectangular board and the long borders are fixedly connected through four positioning bolts located on the four corners. According to the blackboard, the wall can not be damaged during rectangular board replacement, both the long borders and the short borders can be repeatedly used, and cost is saved.
Description
Technical field
The utility model relates to teaching facilities technical field, is specifically related to a kind of blackboard for teaching.
Background technology
In language teaching process, instructors often need to be on blackboard the various poem well-known phrase of writing on the blackboard and text main points and so on.
Traditional blackboard is to be all directly fixed on metope.In order to prevent becoming flexible, existing blackboard is all build-in or adopts other modes to be fastened on metope.Once damaging appears in blackboard, affects writing on the blackboard effect, need to change monoblock blackboard and blackboard frame structure around, even in pulling down blackboard, also can cause damage to metope.Such blackboard can not be convenient for changing, and also can cause very large loss even if change, and needs a lot of costs, causes waste.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of easy accessibility, is beneficial to the blackboard for teaching of replacing.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of blackboard for teaching, comprise rectangle plate body, it is characterized in that, also comprise frame, described frame comprises two long margin frames and two short frames, article two, on long margin frame, be equipped with the long draw-in groove that clamps rectangle plate body, article two, long margin frame is fixed on metope, the length of long margin frame is consistent with the length on the long limit of rectangle plate body, two long checkposts of rectangle plate body are contained in the long draw-in groove on two long margin frames, rectangle plate body is arranged between two long margin frames, article two, on short frame, be equipped with stub groove, two minor faces of the two ends of long margin frame and rectangle plate body are all installed in the stub groove on two short frames, the corner location of the two ends of described short frame and short frame and rectangle plate body offers corresponding positioning screw hole, described short frame, between rectangle plate body and long margin frame, be fixedly connected with by four bolts that are positioned at four jiaos.
As optimal technical scheme of the present utility model, described rectangle plate body is assembled by two above point plate body amalgamations.
As optimal technical scheme of the present utility model, between described point of plate body, assemble by the tongue and groove amalgamation cooperatively interacting.
As optimal technical scheme of the present utility model, described two long margin frames are fixedly mounted on metope by the mode of riveting, being spirally connected or welding.
The beneficial effects of the utility model:
The utility model, in installing, is first fixedly mounted on two long margin frames on metope by the mode of riveting, being spirally connected or welding.Then rectangle plate body is installed between two long margin frames, finally two short frames is arranged on to both sides, and four bolts are fastened on to the position of positioning screw hole, so just blackboard has been arranged on metope.When breakage appears in blackboard, when needing to change, four bolts that come loose, take off two short frames, rectangle plate body can be changed.When the utility model is changed rectangle plate body, can not cause damage to metope, and long margin frame and short frame all can reuse, save cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is decomposition chart of the present utility model.
Fig. 3 is the structural representation of the utility model one rectangle plate body.
In figure: 1, rectangle plate body; 11, divide plate body; 2, long margin frame; 21, long draw-in groove; 3, short frame; 31, stub groove; 4, positioning screw hole; 5, bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to attached Fig. 1 and 2, a kind of blackboard for teaching of the present utility model is proposed, comprise rectangle plate body 1, the utility model also comprises frame, described frame comprises two long margin frames 2 and two short frames 3, article two, on long margin frame 2, be equipped with the long draw-in groove 21 that clamps rectangle plate body 1, article two, long margin frame 2 is fixed on metope, the length of long margin frame 2 is consistent with the length on the long limit of rectangle plate body 1, two long checkposts of rectangle plate body 1 are contained in the long draw-in groove 21 on two long margin frames 2, rectangle plate body 1 is arranged between two long margin frames 2, article two, on short frame 3, be equipped with stub groove 31, two minor faces of the two ends of long margin frame 2 and rectangle plate body 1 are all installed in the stub groove 31 on two short frames 3, the two ends of described long margin frame 2 and short frame 3 and the corner location of rectangle plate body 1 offer corresponding positioning screw hole 4, described short frame 3, between rectangle plate body 1 and long margin frame 2, be fixedly connected with by four bolts 5 that are positioned at four jiaos.In Fig. 1 and Fig. 2, rectangle plate body 1 is an integrated complete plate body structure.The utility model, in installing, is first fixedly mounted on two long margin frames 2 on metope by the mode of riveting, being spirally connected or welding.Then rectangle plate body 1 is installed between two long margin frames, finally two short frames 3 is arranged on to both sides, and four bolts are fastened on to the position of positioning screw hole, so just blackboard has been arranged on metope.When breakage appears in blackboard, when needing to change, four bolts that come loose, take off two short frames, rectangle plate body can be changed.When the utility model is changed rectangle plate body, can not cause damage to metope, and long margin frame and short frame all can reuse, save cost.
With reference to Fig. 3, provide the version of the another kind of rectangle plate body of the utility model.Rectangle plate body 1 is assembled by two above point plate body 11 amalgamations.Between described point of plate body 11, assemble by the tongue and groove amalgamation cooperatively interacting.The benefit of design, is to utilize to greatest extent a point plate body like this.When damaged time, can directly change it and breaking down to obtain one appears in a point of plate body in rectangle plate body, without changing monoblock plate body, improve its utilization rate.Simultaneously such structure, is also conducive to produce, transports and storage, cost-saving.
