Problems solved by technology

[0003] However, conventional molds often use wooden, clay or plastic models of different colors to mark the distribution of strata and contour lines. The molds made in this way can only show the distribution of multi-layer rock strata. However, in the teaching process, It is difficult to show the changes of the rock formations in the process of forming rifts and cliffs, and it will also make it impossible for the trainees to observe the changes of the rock formations intuitively during the learning process, which cannot achieve the purpose of teaching

Embodiment 1

[0033] Embodiment 1 is basically as attached figure 1 And attached figure 2 Shown: a teaching drill device, including a "U"-shaped installation shell 10, a sealed shell 30 with a "U"-shaped longitudinal section, a contour unit, four elastic bags 20, and several support units. Both the shell 10 and the sealing shell 30 are transparent, and four elastic bags 20 are stacked and installed in the installation shell 10 sequentially from top to bottom, and two adjacent elastic bags 20 are integrally formed, and the left end of the elastic bag 20 is connected to the installation shell The left inner wall of 10 is glued, and the right end of the elastic bag 20 is glued to the right inner wall of the installation shell 10, and the elastic bag 20 is made of silica gel.

[0034] Such as figure 1 As shown, the upper end of the sealing case 30 faces down and is opposite to the bottom surface of the installation case 10, and the sealing case 30 is buckled with the installation case 10 to ...

Embodiment 2

[0042] The difference between embodiment 2 and embodiment 1 is that embodiment 2 is basically as attached image 3 And attached Figure 4 As shown, there are no communication holes 102 and blocking blocks 103 on the left and right sides of the installation shell 10, and several jacks 105 are set on the left and right sides of the installation shell 10, and a single elastic bag 20 communicates with the four jacks 105 respectively. , and the jacks 105 are located at four right angles of a single elastic bag 20; meanwhile, several inserts 106 are included, different inserts 106 are filled with different types of rock powder, and the inserts 106 are made of silica gel and have elasticity.

[0043] In addition, each elastic bag 20 is equipped with a sponge.

[0044] A kind of teaching exercise device in the present embodiment has the following difference compared with embodiment 1 when in use, during demonstration, the insert 106 that different kinds of rock powders are housed is ...

Abstract

The invention relates to the field of teaching appliances and particularly discloses a teaching exercise device. The device comprises a mounting shell with a U-shaped longitudinal section, a pluralityof elastic bags filled with marking materials and a plurality of supporting units, wherein the elastic bags are sequentially installed in the mounting shell in an overlapped mode from top to bottom,every two adjacent elastic bags are fixedly connected, and the two ends of each elastic bag are fixedly connected with the two opposite side walls of the mounting shell respectively; the supporting unit comprises a connecting rope and a supporting rod capable of vertically moving, and the upper end of the supporting rod penetrates through the bottom surface of the mounting shell and is fixedly connected with the bottom surface of the lowermost elastic bag; the connecting rope sequentially penetrates through the several elastic bags and is fixedly connected with the upper end of the supportingrod; and the connecting rope is fixedly connected with the several elastic bags. According to the scheme, the supporting unit can push and press the multiple elastic bags, the change conditions of multiple rock stratums under lower side pressure are simulated, the change conditions of the rock stratums can be observed more clearly, and teaching is facilitated.

Description

technical field [0001] The invention belongs to the field of teaching appliances, and in particular relates to a teaching drill device. Background technique [0002] Changes in rock formations and rock masses are compulsory courses in the study of geography. This course involves popular science education in primary and secondary schools and higher education in geology. Changes in rock formations in the earth's crust are not easy to directly observe from nature. The corresponding changes in rock formations can be obtained from text It is also difficult to understand directly in the description, so corresponding display molds are generally made to show the layers of rock formations. [0003] However, conventional molds often use wooden, clay or plastic models of different colors to mark the distribution of strata and contour lines. The molds made in this way can only show the distribution of multi-layer rock strata. However, in the teaching process, It is difficult to show th...
