Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 6 The present invention provides a visual teaching demonstration device with an operable transmission device, comprising: a teaching demonstration device body 1, a workbench 4 mounted on the upper surface of the teaching demonstration device body 1, a transmission device body 5 mounted on the side of the workbench 4 away from the teaching demonstration device body 1, an adjustment device 2 provided on the side of the workbench 4 close to the transmission device body 5, and an auxiliary device 3 provided on the side of the teaching demonstration device body 1 close to the workbench 4.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting device 2 includes a fixed plate 201, which is fixedly connected to the worktable 4. Two support rods 202 are fixedly connected to the side of the fixed plate 201 away from the worktable 4. The arc surfaces of the two support rods 202 that are close to each other are rotatably connected to the same connecting plate 203. A protective cover 213 is fixedly connected to one side of the connecting plate 203. A connecting gear 204 is fixedly connected to one end of the connecting plate 203. The teeth of the connecting gear 204 mesh with an adjusting gear 205. A support plate 207 is fixedly connected to the side of the fixed plate 201 near the support rods 202. A motor 206 is fixedly connected to one side of the support plate 207. The output end of the motor 206 is fixedly connected to one side of the adjusting gear 205. The side of the support plate 207 near the motor 206 is fixedly connected to the motor 206. A cylinder 208 is fixedly connected, and an adjusting plate 209 is fixedly connected to the output end of the cylinder 208. Two limit blocks 210, which are rubber blocks, are fixedly connected to the side of the adjusting plate 209 near the adjusting gear 205. The theoretical teaching of the transmission device body 5 is a key and difficult point in the chassis theory teaching of armored vehicle driving majors. The current auxiliary teaching method is to simplify and reduce the size of the transmission device body 5, and then use 3D printing to make it. The material is POM plastic gear material. The transmission device body 5 is placed on the teaching demonstration equipment body 1 for teaching tasks. The operation of each component of the transmission device body 5 can be seen directly. Power can be cut off by operating the main clutch handle, and gear shifting can be achieved through the shifting mechanism. Finally, the speed sensor can detect the speed. The LCD screen displays the output speed, but when not in use for teaching, the entire transmission device body 5 is exposed to the outside. The entire transmission device body 5 is composed of several gears and operating mechanisms, allowing trainees to perform manual operation during training. However, when not in use, foreign objects can enter the entire transmission device body 5, affecting its subsequent operation and thus its lifespan. In this case, the adjustment device 2 can be used to protect the surface of the transmission device body 5 when it is not in use, preventing foreign objects from entering and extending its lifespan. Both sides of the limiting block 210 are fixed. A fixed connection has several protrusions 211, which are evenly distributed on the limiting block 210. When the limiting block 210 limits the rotation of the connecting gear 204 and the adjusting gear 205, the protrusions 211 on the limiting block 210 can increase the friction on the surface of the limiting block 210. Thus, the protrusions 211 can improve the stability of the limiting block 210 in limiting the rotation of the connecting gear 204 and the adjusting gear 205. A guide rod 212 is fixedly connected to the side of the cylinder 208 near the adjusting plate 209. The arc surface of the guide rod 212 slides through the inner wall of the adjusting plate 209. When the cylinder 208 drives the adjusting plate 209 to move, the guide rod 212 on the cylinder 208 can improve the stability of the adjusting plate 209 during movement.Thus, the guide rod 212 improves the movement effect of the adjusting plate 209. The support plate 207 is made of titanium alloy. The surface of the titanium alloy support plate 207 is relatively hard, and it is less prone to deformation even after long-term use, resulting in a longer service life.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The auxiliary device 3 includes a rotating column 31. One end of the arc surface of the rotating column 31 is fixedly connected to the main body 1 of the teaching demonstration equipment. An adjusting block 32 is fixedly connected to the arc surface of the rotating column 31. A rod 33 slides through the inner wall of the adjusting block 32. A spring 34 is sleeved on the arc surface of the rod 33. The two ends of the spring 34 are fixedly connected to the rod 33 and the adjusting block 32, respectively. A turntable 35 is fixedly connected to the side of the worktable 4 near the rotating column 31. One side of the turntable 35 is rotatably connected to the rotating column 31. Several limiting holes 36 are opened on the side of the turntable 35. The limiting holes 36 are evenly distributed on the turntable 35. The rod 33 slides through the inner wall of one of the limiting holes 36. When it is necessary to adjust the angle of the worktable 4, the angle of the worktable 4 can be adjusted by the auxiliary device 3. The adjustment effect allows the auxiliary device 3 to increase the speed of adjusting the angle of the workbench 4. The workbench 4 is used to rotate the display angle of the transmission device body 5, thereby improving the teaching quality. An auxiliary block 38 is fixedly connected to one end of the arc surface of the insertion rod 33. The auxiliary block 38 is funnel-shaped. When the insertion rod 33 is connected to the limiting hole 36, the auxiliary block 38 installed on the insertion rod 33 can increase the speed of the connection between the insertion rod 33 and the inner wall of the limiting hole 36. Thus, the auxiliary block 38 can improve the efficiency of the connection between the insertion rod 33 and the inner wall of the limiting hole 36. A pull ring 37 is rotatably connected to the inner wall of the insertion rod 33. When it is necessary to pull the insertion rod 33, the pull ring 37 installed on the insertion rod 33 can be used to pull the insertion rod 33. The pull ring 37 can improve the speed and efficiency of pulling the insertion rod 33.

[0036] The working principle of the visual teaching demonstration device with operable transmission device provided by this utility model is as follows: A support plate 207 is installed on the main body 1 of the teaching demonstration device. When the motor 206 installed on the support plate 207 is started, the motor 206 drives the adjusting gear 205 to rotate through the output end. The rotation of the adjusting gear 205 drives the connecting gear 204 to move, thereby driving the connecting plate 203 to move through the connecting gear 204. The movement of the connecting plate 203 drives the protective cover 213 to move, thus moving the protective cover 213 closer to the transmission device body 5. The protective cover 213 protects the surface of the transmission device body 5. When the cylinder 208 is started, the movement of the cylinder 208 drives the adjusting plate 209 to move. The movement of the adjusting plate 209 drives the limiting block 210 to connect with the meshing point of the adjusting gear 205 and the connecting gear 204. The limiting block 210 meshes the connection point of the two, thereby improving the stability of the connecting gear 204 and the adjusting gear 205 when they are not rotating.

[0037] Pulling the insertion rod 33 causes the spring 34 to deform, allowing the insertion rod 33 to be pulled out of the limiting hole 36, thus releasing the fixing effect on the turntable 35. The angle of the worktable 4 can then be adjusted by rotating the turntable 35 on the teaching demonstration equipment body 1, thereby adjusting the angle of the transmission device body 5 via the worktable 4. After adjusting the worktable 4 to the appropriate position, the insertion rod 33 can be released, and the spring 34 will reset, causing the insertion rod 33 to connect with the inner wall of the limiting hole 36, thus fixing the worktable 4 again.

[0038] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
