[0021] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0022] Please refer to the attached Figure 1-5, combined with a specific embodiment, it is explained as follows: the innovative teaching sandbox described in the utility model includes a plurality of geographical sandboxes 1 and a storage box 2 for geography teaching, the geographical sandbox 1 simulates the gradual changes in geography, the plurality of geographical sandboxes 1 are arranged inside the storage box 2, and the side of each geographical sandbox 1 close to the inner wall of the storage box 2 is in contact with the inner wall; the opening length of the storage box 2 is greater than the overall length of the two geographical sandboxes 1, and an adjustment mechanism 3 for adjusting the position of the geographical sandbox 1 is arranged between the inner wall of the storage box 2 and the geographical sandbox 1, and a positioning mechanism 4 for limiting the geographical sandbox 1 is arranged inside the box wall of the storage box 2.
[0023] Since the opening length of the storage box 2 is greater than the overall length of the two geographic sand tables 1, two geographic sand tables 1 can be placed inside the opening at the same time to coordinate the movement of the geographic sand tables 1 inside the storage box 2, so that students can compare the two geographic sand tables 1 in turn through their eyes, so that students can intuitively observe the geographical changes, and ultimately make it easier for students to understand what the teacher is explaining.
[0024] Specifically, the adjustment mechanism 3 includes two adjustment grooves 31, and the two adjustment grooves 31 are arranged opposite to each other on the inner wall of the storage box 2; the adjustment groove 31 includes a limit groove 311 and four guide grooves 312, the limit groove 311 is horizontally arranged, and the four guide grooves 312 are vertically arranged on the bottom side of the corresponding limit groove 311, and each guide groove 312 is connected to the limit groove 311.
[0025] The adjustment groove 31 composed of the limit groove 311 and the four guide grooves 312 can constrain the moving trajectory of the geographic sand table 1 inside the storage box 2, that is, to make the geographic sand table 1 move along the trajectory of the adjustment mechanism 3 inside the storage box 2.
[0026] Specifically, a plurality of rollers 32 are rotatably provided on the outer side of the geographic sand table 1 through bearings, and one end of the roller 32 away from the corresponding geographic sand table 1 is inserted into the corresponding adjustment groove 31, and the outer peripheral wall of the roller 32 contacts the inner wall of the corresponding adjustment groove 31.
[0027] The above-mentioned adjustment groove 31 constrains the trajectory of the geographic sand table 1, which can be achieved by the roller 32 rolling inside the adjustment groove 31, and the rotation of the roller 32 inside the adjustment groove 31 can greatly reduce the resistance encountered by the geographic sand table 1 when moving.
[0028] Specifically, the positioning mechanism 4 includes a positioning rod 41, which is fixed on the inner bottom wall of the limiting groove 311, and a ball 42 is embedded in the end of the positioning rod 41 away from the inner bottom wall of the corresponding limiting groove 311; the outer peripheral wall of the roller 32 away from the end of the corresponding geographic sand table 1 is an arc structure, and a hemispherical groove 43 is opened at the center position of the side of the roller 32 away from the corresponding geographic sand table 1, and the end of the ball 42 away from the positioning rod 41 is inserted into the corresponding hemispherical groove 43.
[0029] When the outer arc surface of the roller 32 and the outer arc surface of the ball 42 collide with each other with great force, the ball 42 can be squeezed out of the limiting groove 311 along the outer arc surface of the roller 32, so that the roller 32 can roll into the limiting groove 311 from the guide groove 312 or continue to roll along the limiting groove 311; when the outer arc surface of the roller 32 and the inner arc surface of the hemispherical groove 43 collide with each other with great force, the ball 42 can be squeezed out of the hemispherical groove 43 along the outer arc surface of the ball 42, so that the restrained limiting state of the roller 32 is automatically released, and the operator does not need to perform other operations. It is convenient to adjust the position of the geographic sand table 1.
[0030] Specifically, an air storage groove 44 for installing the positioning rod 41 is opened on the inner bottom wall of the limit groove 311, the air storage groove 44 is located above the corresponding guide groove 312, and the interior of the air storage groove 44 is filled with air; the positioning rod 41 is arranged inside the corresponding air storage groove 44, and the outer peripheral side of the positioning rod 41 is sleeved with a sealing ring for sealing the gap between the positioning rod 41 and the inner wall of the corresponding air storage groove 44, and the outer peripheral wall of the positioning rod 41 is in contact with the inner wall of the corresponding air storage groove 44; it should be noted that the air filled in the air storage groove 44 is high-pressure air of appropriate size.
[0031] The high-pressure air inside the air storage tank 44 can continuously apply a thrust to the positioning rod 41 in the direction of the limit groove 311. During the movement of the above-mentioned roller 32 inside the limit groove 311, when the ball 42 is aligned with the hemispherical groove 43, the air inside the air storage tank 44 automatically pushes the ball 42 into the hemispherical groove 43 through the positioning rod 41, and through the mutual interference between the outer arc surface of the ball 42 and the inner wall of the hemispherical groove 43, a restraining force is applied to the roller 32 to cooperate with the mutual interference between the outer peripheral wall of the roller 32 and the inner wall of the limit groove 311, so that the geographical sand table 1 can be placed more stably in the opening of the storage box 2.
[0032] In one embodiment, a support rod 5 is fixed at the center of the top side of the geographic sand table 1, and the top side of the support rod 5 is higher than the top side of the corresponding geographic sand table 1. When the geographic sand tables 1 are stacked at the bottom of the storage box 2, since the bottom side of the upper geographic sand table 1 and the support rod 5 on the lower geographic sand table 1 conflict with each other, there is enough space between the bottom side of the upper geographic sand table 1 and the top side of the lower geographic sand table 1, so that the stacking of the geographic sand tables 1 will not cause damage to the sand tables.
[0033] The use principle of the utility model is as follows: when the teacher uses the sand table for auxiliary teaching, the operator holds the support rod 5 to pull the geographical sand table 1 upward, and as the roller 32 rotates inside the guide groove 312, the geographical sand table 1 moves vertically upward. When the roller 32 contacts the ball 42, due to the mutual interference between the arc surface of the roller 32 and the outer arc surface of the ball 42, the ball 42 can be squeezed into the air storage groove 44 along the outer arc surface of the ball 42, so that the ball 42 will not affect the insertion of the roller 32 into the limit groove 311. ; It should be noted that in the process of the roller 32 squeezing the ball 42 into the air storage tank 44, due to the mutual interference between the ball 42 and the positioning rod 41, the positioning rod 41 can move toward the bottom side of the air storage tank 44, compressing the air in the air storage tank 44; after the ball 42 moves into the limit groove 311, the operator holds the support rod 5 and pushes the support rod 5 laterally, so that the geographic sand table 1 moves laterally along the limit groove 311, and the geographic sand table 1 can be moved to the other side of the opening of the storage box 2.
[0034] During the process of the above-mentioned geographic sand table 1 moving along the linear trajectory of the limit groove 311, if the hemispherical groove 43 and the ball 42 are re-balanced, the internal gas of the air storage groove 44 pushes the positioning rod 41, so that the ball 42 can extend out of the air storage groove 44 and insert into the hemispherical groove 43 again, and due to the mutual interference between the ball 42 and the inner wall of the hemispherical groove 43, a restraining force can be applied to the roller 32, so that when the roller 32 is in the limit groove 311, the position will not move without external force. With the mutual interference between the roller 32 and the inner wall of the limit groove 311, the geographic sand table 1 is placed more stably in the opening of the storage box 2.
[0035] It should be noted that after the above-mentioned ball 42 is reinserted into the hemispherical groove 43, the operator continues to push the geographic sand table 1. Due to the mutual interference between the outer arc wall of the ball 42 and the inner arc wall of the hemispherical groove 43, the ball 42 can be squeezed out of the hemispherical groove 43, and the ball 42 can be squeezed back into the air storage tank 44 through the mutual interference between the ball 42 and the roller 32, so that the geographic sand table 1 can be moved again.
[0036] When the rollers 32 on both sides of the geographic sand table 1 are all moved to the top of the guide groove 312, the operator holds the support rod 5 and pushes the geographic sand table 1 downward, and the ball 42 is squeezed back into the air storage tank 44, so that the roller 32 can roll into the guide groove 312, and because the outer wall of the roller 32 and the inner wall of the guide groove 312 are mutually conflicting, the geographic sand table 1 moves vertically downward and is stored in the storage tank. Finally, the teacher adjusts the position of the geographic sand table 1 according to the above, selects the required geographic sand table 1 and places it in the opening of the storage box 2 for demonstration and teaching.
