Description

Technical Field

[0001] The invention belongs to the technical field of campus e-commerce teaching, and in particular relates to a campus e-commerce teaching platform and equipment. Background Art

[0002] The campus e-commerce teaching platform is a platform designed specifically for teaching purposes. It mainly helps students understand and practice the mutual knowledge and skills of e-commerce by simulating a real e-commerce environment. The functions of the campus e-commerce teaching platform usually include product management, transaction management, marketing activities and other aspects, which are used to simulate various scenarios in the real business environment and help students gain practical operation experience in the learning process.

[0003] The campus e-commerce teaching platform is mainly composed of business teaching software, teaching displays, servers, audio and video equipment and other ancillary devices. In the actual application process, the teaching content is displayed in real time through the teaching display. Students can watch and operate the teaching content through the teaching display and control devices such as mouse and keyboard, so as to gain practical operation experience in the learning process.

[0004] Most of the teaching displays of campus e-commerce teaching platforms in the prior art are mostly fixed in place. In actual application, the teaching displays are not adjusted at multiple angles according to actual needs, which makes the viewing and learning effect of the campus e-commerce teaching platform poor. At the same time, since the teaching displays are exposed to the air, the teaching displays are easily affected by static electricity and environmental factors, resulting in dust adhesion, which affects the actual viewing effect of the teaching displays.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0050] like Figures 2 to 5 As shown, an elevation adjustment assembly is installed between the assembly frame 204 and the fixed inner platform 202. The elevation adjustment assembly includes a driving base 211, which is hingedly installed below the assembly frame 204 and slidably installed in the fixed inner platform 202. The driving base 211 supports and limits the assembly frame 204. At the same time, the teaching display 203 can be folded, stored, and the angle can be adjusted by moving and controlling the driving base 211.

[0051] like Figures 2 to 5 As shown, a pair of movable lead screws 212 are threadedly connected to the bottom of the driving base 211, and both ends of the pair of movable lead screws 212 are rotatably connected to the fixed inner platform 202. The movable lead screws 212 play the role of thread limit and movement control for the driving base 211.

[0052] like Figures 4 to 6 As shown, one end of a pair of movable lead screws 212 located outside the fixed inner platform 202 is fixedly connected to a synchronous gear 213. The movable lead screws 212 are rotationally driven by the synchronous gear 213.

[0053] like Figures 4 to 6 As shown, a synchronous belt 214 is meshed with the outer side of the synchronous gear 213. The synchronous belt 214 plays a role of synchronously driving the pair of synchronous gears 213.

[0060] like Figures 8 to 10 As shown, a partition 302 is fixedly installed in the dust filter cartridge 301, and the partition 302 divides the dust filter cartridge 301 into a dust filter chamber and a flow guide chamber. The partition 302 is used to separate the dust filter cartridge 301 into a space, and at the same time, the partition 302 is used to assemble and fix multiple groups of dust filter bags 305.

[0061] like Figures 8 to 10 As shown, multiple groups of evenly distributed dust filter bags 305 are inserted into the partition 302, and the openings of the multiple groups of dust filter bags 305 are connected to the guide cavity. The multiple groups of dust filter bags 305 filter dust from the air guided by the negative pressure guide pipe 303.

[0062] like Figures 8 to 10 As shown, a negative pressure guide pipe 303 is inserted into the dust filter cartridge 301, and the negative pressure guide pipe 303 is in communication with the dust filter chamber. The negative pressure guide pipe 303 guides and transports the air collected by the negative pressure air collecting pipe 304.

[0063] like Figures 4 to 8 As shown, one end of the negative pressure guide tube 303 outside the dust filter cartridge 301 is fixedly connected to a negative pressure air collecting tube 304, and the side of the negative pressure guide tube 304 away from the negative pressure guide tube 303 is in the same horizontal plane as the inner wall of the fixed inner platform 202. The negative pressure air collecting tube 304 collects and guides the air in the storage tank under negative pressure.

[0064] like Figures 8 to 10 As shown, a positive pressure dust cleaning assembly is installed above the dust filter cartridge 301. The positive pressure dust cleaning assembly includes a pair of exhaust fans 306, which are fixedly installed above the dust filter cartridge 301 and are connected to the guide cavity. The air in the guide cavity is guided out by controlling the operation of the pair of exhaust fans 306, so that the dust filter cartridge 301 is in a negative pressure state, which provides a basis for subsequent air extraction.

[0065] like Figures 8 to 10As shown, one end of the exhaust fan 306 outside the flow guiding cavity is connected to a flow guiding cover 307. The flow guiding cover 307 plays a role of gas flow guiding and limiting for the exhaust fan 306.

[0066] like Figures 8 to 10 As shown, the air delivery pipe 308 is connected to the top of the air guide cover 307, and a guide groove is provided on the top of the box seat 1, and the air delivery pipe 308 is connected to the guide groove. The air delivery pipe 308 serves to connect the guide groove with the air guide cover 307, so that the air in the air guide cover 307 can be guided and discharged through the air delivery pipe 308.

[0067] like Figures 8 to 10 As shown, an exhaust pipe 309 is fixedly mounted in the rotating gear ring 205, and the exhaust pipe 309 is arranged in cooperation with the guide groove. The exhaust pipe 309 guides the gas transported in the guide groove.

[0068] like Figures 8 to 10 As shown, one end of the exhaust pipe 309 located in the fixed inner platform 202 is connected to the conducting air pipe 310. The dust cleaning air nozzle 311 serves to connect the exhaust pipe 309 with the plurality of dust cleaning air nozzles 311.

[0069] like Figures 8 to 10 As shown, multiple groups of dust-cleaning air nozzles 311 are fixedly connected to the inner wall of the fixed inner platform 202, and the multiple groups of dust-cleaning air nozzles 311 are all connected to the conductive air pipe 310, and the gas outlets of the multiple groups of dust-cleaning air nozzles 311 face the surface of the teaching display 203. It is convenient to blow and clean the teaching display 203 by spraying gas through the multiple groups of dust-cleaning air nozzles 311.

[0070] like Figures 8 to 11 As shown, the supporting sealing mechanism 4 is fixedly assembled above the fixed inner platform 202 , and the supporting sealing mechanism 4 is used for providing shock-absorbing support and sealing and dust-clearing limit to the teaching display 203 .

[0071] like Figures 8 to 11 As shown, the supporting sealing mechanism 4 includes a sealing airbag cushion 401, which is fixedly assembled above the fixed inner platform 202. The sealing airbag cushion 401 plays a role of buffering, limiting and sealing protection in the folding and storage process of the teaching display 203. The risk of the teaching display 203 being damaged by collision during the folding and storage process is avoided. At the same time, the dust and humid air in the environment are prevented from being filled on the outside of the teaching display 203 due to loose sealing.

[0072] like Figures 8 to 11 As shown, a guide air pipe 402 is connected below the sealed airbag cushion 401. The guide air pipe 402 connects the sealed airbag cushion 401 and the piston cylinder 403.

[0073] like Figures 8 to 11As shown, one end of the air guide tube 402 away from the sealing airbag cushion 401 is connected to a piston cylinder 403. The piston cylinder 403 receives and controls the movement of the piston block 404.

[0074] like Figures 8 to 11 As shown, a piston block 404 is slidingly and sealingly assembled in the piston cylinder 403. The outer side of the assembly frame 204 is sealed and limited by the ejection of the piston block 404.

[0075] like Figures 8 to 11 As shown, the end of the piston cylinder 403 away from the piston block 404 is connected to the air supply pipe 405. The air supply pipe 405 connects and conducts the piston cylinder 403 and the one-way conducting valve body 406.

[0076] like Figures 8 to 11 As shown, one end of the air supply pipe 405 away from the piston cylinder 403 is connected to a one-way valve body 406. The one-way valve body 406 controls the one-way communication between the air supply pipe 405 and the return air pipe 409.

[0077] Specifically, a conical flow guide hole is provided in the one-way guide valve body 406, and a valve ball 407 is provided inside the conical flow guide hole. The one-way guide valve body 406 is blocked in one direction by the mutual cooperation between the valve ball 407 and the conical flow guide hole.

[0078] like Figures 8 to 11 As shown, a limit spring 408 is arranged on one side of the valve ball 407 close to the one-way valve body 406. The valve ball 407 is supported and limited by the contraction and reset of the limit spring 408.

[0079] like Figures 8 to 11 As shown, a return air pipe 409 is connected between the one-way guide valve body 406 and the guide air pipe 310, and the diameter of one end of the conical guide hole close to the return air pipe 409 is smaller than the diameter of the other end. The return air pipe 409 serves to connect the guide air pipe 310 and the one-way guide valve body 406, so that the gas in the guide air pipe 310 is transported to the one-way guide valve body 406 along the return air pipe 409.

[0080] A campus e-commerce teaching device comprises a campus e-commerce teaching platform.

[0081] When used specifically, the folding motor 220 can be controlled to drive the driving pulley 219 to rotate, so that the assembly shaft 216 rotates synchronously with the rotation of the output shaft of the folding motor 220 under the cooperation of the synchronous belt 218 and the driving pulley 217, and the synchronous toothed belt 214 is driven to move by the assembly shaft 216 driving the transmission gear 215 to rotate, and a pair of moving screws 212 rotate synchronously under the meshing action of the synchronous gear 213 and the synchronous toothed belt 214, and the driving base 211 can drive the assembly frame 204 to move under the action of the internal and external threads. The assembly frame 204 is pulled and raised by the movement of the driving base 211 and the telescopic connecting rod 210. At the same time, the elevation angle of the assembly frame 204 can be controlled by the driving base 211 moving along the moving screw 212, so that the teaching display 203 can be adaptively adjusted according to requirements.

[0082] At the same time, the adjusting gear 206 can be driven to rotate by controlling the operation of the rotating adjusting motor 207, and the fixed inner platform 202 rotates under the meshing action of the rotating gear ring 205 and the adjusting gear 206, so as to adjust the horizontal angle of the teaching display 203. By adjusting the teaching display 203 at multiple angles, the viewing and learning effect of the teaching display 203 is greatly improved.

[0083] When the teaching display 203 needs to be folded and stored, the driving base 211 can be moved and controlled by controlling the folding motor 220 to rotate in the opposite direction, so that the assembly frame 204 can be stored between the rotating assembly table 201 and the fixed inner platform 202. During the storage process of the teaching display 203, the teaching display 203 can be buffered and limited by the cooperation between the sealing airbag cushion 401 and the piston block 404.

[0084] When the teaching display 203 is folded and stored, the air in the dust filter cylinder 301 can be extracted by controlling the operation of a pair of exhaust fans 306. The gas generated during the operation of the exhaust fan 306 can be transported to the guide air pipe 310 along the guide cover 307, the conveying air pipe 308, and the exhaust pipe 309, and blown to the teaching display 203 by multiple sets of dust-cleaning air nozzles 311, so as to blow and clean the teaching display 203. In addition, the teaching display 203 can be assisted in cooling down by blowing air. At the same time, the dust filter cylinder 301 is in a negative pressure state under the action of the pair of exhaust fans 306, and the dust-containing gas blown off the teaching display 203 is extracted through the negative pressure guide pipe 303 and the negative pressure gas collecting pipe 304, and the gas can be filtered through multiple sets of dust filter bags 305.

[0085] In addition, the gas in the ventilation pipe 310 can be transported to the one-way guide valve body 406 along the return air pipe 409, and the valve ball 407 compresses the limit spring 408 under the action of gas pressure. The gas in the ventilation pipe 310 is transported to the piston cylinder 403 and the sealed airbag cushion 401 along the return air pipe 409, the one-way guide valve body 406, and the air supply pipe 405. The piston block 404 and the sealed airbag cushion 401 expand or move under the action of gas, so that the sealed airbag cushion 401 and the piston block 404 can assist in sealing the assembly frame 204, which not only ensures the storage stability of the assembly frame 204, but also improves the effect of blowing air to clean dust on the teaching display 203.
