Specific embodiments

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to the attached Figure 1 - attached Figure 10 , an art work design teaching display device provided by an embodiment of the present invention includes a mounting post 1. A reset mechanism 2 is arranged inside the mounting post 1. An anti-sliding mechanism 3 is arranged in the middle of the mounting post 1. After an art work is placed on the top of the reset mechanism 2, the anti-sliding mechanism 3 is used to prevent the art work from slipping. A fitting mechanism 4 is arranged on the top of the anti-sliding mechanism 3. The fitting mechanism 4 can be attached to the outside of the art work. The bottom of the mounting post 1 is rotatably connected to a base 6. The base 6 is used for the rotation of the mounting post 1. An anti-rotation mechanism 5 is arranged outside the base 6. The anti-rotation mechanism 5 is used to prevent the mounting post 1 from rotating without external force.

[0031] The reset mechanism 2 includes a plurality of mounting grooves 201 which provide mounting positions. The plurality of mounting grooves 201 are all opened inside the mounting post 1. A first spring 202 is arranged inside the mounting groove 201. A limiting block 203 is slidably connected inside the mounting groove 201. The limiting block 203 has a limiting function. A connecting post 204 is fixedly connected to the top of the limiting block 203. A placing plate 205 is fixedly connected between the tops of the plurality of connecting posts 204. The connecting post 204 can be connected to the placing plate 205. The first spring 202 can use its own elastic force to push the limiting block 203, the connecting post 204 and the placing plate 205 to move upward for reset. One end of the first spring 202 is fixedly connected inside the mounting groove 201, and the other end of the first spring 202 is fixedly connected to the bottom of the limiting block 203. When a ceramic art craft is placed on the placing plate 205, it can press the placing plate 205 downward under the action of gravity, and then can drive the connecting post 204 to move downward, and then can drive the limiting block 203 to move downward, so as to compress the first spring 202. When the ceramic art craft is taken away from the placing plate 205, under the action of the reaction force of the first spring 202, the limiting block 203 is pushed to move upward, and then can drive the connecting post 204 to move upward, and then can drive the placing plate 205 to move upward. At this time, the placing plate 205 is reset.

[0032] The anti-slip mechanism 3 includes a limit post 301. The bottom of the limit post 301 is fixedly connected to the middle of the mounting post 1. A sliding ring 302 is slidably connected to the outside of the limit post 301. The limit post 301 can limit the movement track of the sliding ring 302. A plurality of connecting rods 303 are rotatably connected to the outside of the sliding ring 302. The middle part of the bottom end of the placing plate 205 is fixedly connected with a sleeve 304. When the sleeve 304 moves downward following the placing plate 205, it can push the sliding ring 302 downward. The inside of the sleeve 304 is slidably connected to the outside of the limit post 301. The top of the connecting rod 303 is rotatably connected with a limit slider 307. The top of the limit slider 307 is fixedly connected with a telescopic rod 308. The telescopic rod 308 has the function of self-expansion and contraction, so that there will be no movement interference when the placing plate 205 moves downward. The top of the telescopic rod 308 is fixedly connected with a sliding block 305. The top of the mounting post 1 is fixedly connected with a fixed limit plate 309. The fixed limit plate 309 has a limiting function. When the bottom of the connecting rod 303 moves downward under the limitation of the fixed limit plate 309, the movement track of the limit slider 307 can be limited by the fixed limit plate 309, so that the top of the connecting rod 303 moves towards the middle. A plurality of limit sliders 307 are all slidably connected to the inside of the fixed limit plate 309. A plurality of limit grooves 306 are formed in the inside of the placing plate 205. The sliding block 305 is slidably connected to the inside of the limit groove 306. When the placing plate 205 moves downward, it can drive the sleeve 304 to move downward, thereby pushing the sliding ring 302 downward. When the sliding ring 302 moves downward, it can drive the bottom of the connecting rod 303 to move downward. Since the top of the connecting rod 303 is limited by the limit slider 307 and the fixed limit plate 309, the limit slider 307 will move towards the middle of the fixed limit plate 309, and then can drive the telescopic rod 308 to move towards the middle. The telescopic rod 308 drives the sliding block 305 to move towards the middle of the placing plate 205, and then can drive the fitting mechanism 4 to move towards the middle and fit on the outside of the art and craft work, thereby preventing the art and craft work from slipping out of the top of the placing plate 205.

[0033] The fitting mechanism 4 includes a plurality of mounting seats 401 which provide mounting positions. The bottoms of the plurality of mounting seats 401 are respectively fixedly connected to the tops of a plurality of sliding blocks 305. A rotating pin 402 is rotatably connected inside the mounting seat 401, and the rotating pin 402 can play a mounting role. A first torsion spring 403 is arranged inside both ends of the mounting seat 401. The middle part of the rotating pin 402 is fixedly connected to a housing 404 which provides a mounting position. When there is no external force acting on the housing 404, the rotating pin 402 will be reset under the reaction force of the first torsion spring 403, and then the housing 404 can be reset. A second spring 405 is arranged inside the housing 404. A limiting plate 406 is slidably connected inside the housing 404, and the limiting plate 406 has a limiting function. The top of the limiting plate 406 is fixedly connected to a movable column 407 which can retract into the housing 404. When the movable column 407 moves towards the inside of the housing 404, the elasticity of the second spring 405 can be utilized so that when the art craft work contacts the flexible fitting piece 411, it is not a rigid contact but a flexible contact. One end of the movable column 407 away from the limiting plate 406 is fixedly connected to a fixing pin 408. The fixing pin 408 is rotatably connected to the outside of a fixing block 409. A second torsion spring 410 is arranged inside the fixing block 409. One end of the fixing block 409 away from the movable column 407 is fixedly connected to a flexible fitting piece 411. When there is no external force acting on the flexible fitting piece 411, the second torsion spring 410 can utilize its own elastic force to reset the fixing pin 408, and then the fixing block 409 and the flexible fitting piece 411 can be reset. One end of the second torsion spring 410 is fixedly connected to the outside of the fixing pin 408, and the other end of the second torsion spring 410 is fixedly connected to the inside of the fixing block 409. The second torsion spring 410 is sleeved on the outside of the fixing pin 408. The fixing block 409 is arranged inside one end of the movable column 407 away from the limiting plate 406. The movable column 407 penetrates through the top of the housing 404. An anti-slip pad is arranged on the side of the flexible fitting piece 411 away from the movable column 407. After the flexible fitting piece 411 is attached to the outside of the art craft work, the flexible fitting piece 411 rotates under the thrust of the sliding block 305, and then can be attached to the outside of the art craft work. At the same time, after the flexible fitting piece 411 clamps the art craft work, the housing 404 will continue to move towards the direction of the flexible fitting piece 411, and the limiting plate 406 is used to compress the second spring 405. The elastic force of the second spring 405 is utilized to make the flexible fitting piece 411 and the art craft work in a flexible contact, avoiding direct rigid contact from damaging the outside of the art craft work. At the same time, the direction of the force after the flexible fitting piece 411 contacts the art craft work is adjusted by the rotation of the housing 404, and then the flexible fitting piece 411 can be more closely attached to the outside of the art craft work.

[0034] The anti-rotation mechanism 5 includes a rotating rod 501. The bottom of the rotating rod 501 is rotatably connected to the outside of the base 6. On one side of the top of the rotating rod 501 close to the mounting post 1, a friction block 502 is fixedly connected. The friction block 502 can increase the friction force. On the side of the bottom of the rotating rod 501 away from the mounting post 1, a pedal 503 is fixedly connected. Stepping on the pedal 503 can drive the rotating rod 501 to rotate, and then can drive the friction block 502 away from the outside of the mounting post 1. A rotating cylinder 504 is rotatably connected to the outside of the base 6. The rotating cylinder 504 can provide an installation position. A pushing spring 505 is arranged inside the rotating cylinder 504. A limiting circular block 506 is slidably connected inside the rotating cylinder 504. On the top of the limiting circular block 506, a movable rod 507 is fixedly connected. The pushing spring 505 can use its own elastic force to push the limiting circular block 506 and the movable rod 507 to extend towards the mounting post 1, and can drive the rotating rod 501 to rotate towards the mounting post 1, and by means of the elastic force of the pushing spring 505, the friction block 502 can be tightly attached to the outside of the mounting post 1, and then the rotation of the mounting post 1 can be prevented in case of accidental collision. The top of the movable rod 507 is rotatably connected to one side of the top of the rotating rod 501. The outside of the movable rod 507 penetrates through the top of the rotating cylinder 504. One end of the pushing spring 505 is fixedly connected to the inside of the rotating cylinder 504, and the other end of the pushing spring 505 is fixedly connected to the bottom of the limiting circular block 506. When it is necessary to observe the art work comprehensively, in order to allow the personnel to be learned not to move, at this time, it is necessary to rotate the mounting post 1, thereby driving the art work to rotate. When rotating the mounting post 1, first step on the pedal 503 downward, and then the bottom of the rotating rod 501 can be driven to rotate, so that the rotating rod 501 can be driven to rotate and tilt, and then the friction block 502 can be driven away from the outside of the mounting post 1. At the same time, when the rotating rod 501 rotates, it can push the movable rod 507 to move towards the inside of the rotating cylinder 504, and then drive the limiting circular block 506 to move towards the side away from the movable rod 507. At this time, the pushing spring 505 can be compressed by the limiting circular block 506. When the rotation of the mounting post 1 is not required, release the pedal 503. Under the action of the pushing spring 505, the limiting circular block 506 and the movable rod 507 are pushed upward, and then the rotating rod 501 can be driven to rotate towards the mounting post 1, and the friction block 502 is tightly attached to the outside of the mounting post 1, and then the friction force of the friction block 502 can be used to prevent the mounting post 1 from rotating after accidental collision with the mounting post 1.

[0035] Working principle: When the ceramic arts and crafts works are placed on the placing plate 205, under the action of gravity, the placing plate 205 can be pressed downward, and then the connecting column 204 can be driven to move downward, and then the limiting block 203 can be driven to move downward, so as to compress the first spring 202. When the ceramic arts and crafts works are removed from the placing plate 205, under the action of the reaction force of the first spring 202, the limiting block 203 is pushed to move upward, and then the connecting column 204 can be driven to move upward, and then the placing plate 205 can be driven to move upward. At this time, the placing plate 205 is reset;

[0036] When the placing plate 205 moves downward, it can drive the sleeve 304 to move downward, so as to push the sliding ring 302 downward. When the sliding ring 302 moves downward, it can drive the bottom of the connecting rod 303 to move downward. Since the top of the connecting rod 303 is limited by the limiting slider 307 and the fixed limiting plate 309, the limiting slider 307 will move toward the middle of the fixed limiting plate 309, and then the telescopic rod 308 can be driven to move toward the middle. The telescopic rod 308 drives the sliding block 305 to move toward the middle of the placing plate 205, and then the fitting mechanism 4 can be driven to move toward the middle and fit on the outside of the arts and crafts works, so as to prevent the arts and crafts works from slipping out of the top of the placing plate 205;

[0037] After the flexible fitting piece 411 fits on the outside of the arts and crafts works, the flexible fitting piece 411 rotates under the thrust of the sliding block 305, and then can be attached to the outside of the arts and crafts works. At the same time, after the flexible fitting piece 411 clamps the arts and crafts works, the outer shell 404 will continue to move toward the flexible fitting piece 411, and the limiting plate 406 is used to squeeze the second spring 405. The elastic force of the second spring 405 makes the flexible contact between the flexible fitting piece 411 and the arts and crafts works, avoiding direct rigid contact from damaging the outside of the arts and crafts works. At the same time, the direction of the force after the flexible fitting piece 411 contacts the arts and crafts works is adjusted by the rotation of the outer shell 404, so that the flexible fitting piece 411 can fit more closely to the outside of the arts and crafts works;

[0038] When a comprehensive observation of the arts and crafts work is required, in order to enable the personnel to be trained not to move, the mounting column 1 needs to be rotated at this time, so as to drive the arts and crafts work to rotate. When rotating the mounting column 1, first step on the pedal 503 downward, and then the bottom of the rotating rod 501 can be driven to rotate, so that the rotating rod 501 can be driven to rotate and tilt, and then the friction block 502 can be driven to leave the outside of the mounting column 1. At the same time, when the rotating rod 501 rotates, it can push the movable rod 507 to move into the rotating cylinder 504, and then drive the limiting round block 506 to move away from one side of the movable rod 507. At this time, the limiting round block 506 can be used to compress and push the spring 505. When the mounting column 1 does not need to rotate, release the pedal 503. Under the action of the pushing spring 505, the limiting round block 506 and the movable rod 507 are pushed upward, and then the rotating rod 501 can be driven to rotate in the direction of the mounting column 1, and the friction block 502 can be made to closely adhere to the outside of the mounting column 1, and then the friction force of the friction block 502 can be used to prevent the mounting column 1 from rotating by mistake after being accidentally touched.
