Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a vocabulary contrast explanation device for college English teaching comprises a rack 1, a support rod 2, a clamping rod 3, a fixing hole 4, a fixed gear 5, a support column 6, a connecting column 7, a connecting frame 8, a fixing rod 9, a spring 10, a vocabulary card 11, a baffle 12, a magnetic block 13, a sucker 14, a fixing block 15 and a screw 16, wherein the right side of the rack 1 is provided with the fixing hole 4, the right side of the rack 1 is internally connected with the support rod 2, the inside of the support rod 2 is provided with the clamping rod 3, the outer side of the support rod 2 is connected with the fixed gear 5, the fixed gear 5 is positioned inside the rack 1, the left end of the fixed gear 5 is fixed with the support column 6, the inside of the support column 6 is provided with the connecting column 7, the side of the connecting column 7 is fixed with the connecting frame 8, the inside of the side of the connecting frame 8 is respectively, the inside of link 8 is provided with vocabulary card 11, and the length of vocabulary card 11 is greater than the length of link 8 to the two constitutes dismantlement mounting structure, and the left side internal connection of frame 1 has baffle 12, and the lower extreme of baffle 12 and the inside of frame 1 are provided with magnetic path 13, and the rear side of frame 1 is fixed with sucking disc 14, and the internal connection of sucking disc 14 has fixed block 15, and the lower extreme of fixed block 15 is provided with screw rod 16.

Frame 1 and bracing piece 2 constitute revolution mechanic, and bracing piece 2 is provided with 2 about the line of demarcation symmetry of 1 the central axis of frame, and 2 bracing pieces 2 are connected for the meshing through fixed gear 5, bracing piece 2 and kelly 3 are sliding connection, and kelly 3 and fixed orifices 4 are connected for the block, and the angle setting such as fixed orifices 4 is in the side of frame 1, when using the device, drive fixed gear 5 through rotating bracing piece 2 and rotate, thereby make the vocabulary card 11 of upper and lower both sides rotate, the vocabulary on the vocabulary card 11 of both sides contrasts the explanation, after vocabulary card 11 rotates and finishes, move kelly 3 left, make its embedded inside of installing at fixed orifices 4, thereby fix bracing piece 2 and vocabulary card 11.

Support column 6 and spliced pole 7 are sliding connection, and angles such as spliced pole 7's side are provided with link 8, and link 8 and dead lever 9 constitute extending structure, the inside of link 8 is provided with vocabulary card 11, when the pivoted support pole 2, link 8 rotates thereupon, thereby reach the purpose of switching the vocabulary, and when learning finishes the back and need change vocabulary card 11, with dead lever 9 rebound, make dead lever 9 no longer to vocabulary card 11 suppression, because the length of vocabulary card 11 is greater than the length of link 8, so be convenient for take out vocabulary card 11 from the inside of device, later put into the inside of device with new vocabulary card 11, spring 10 promotes dead lever 9 and moves down this moment, thereby fix vocabulary card 11.

Baffle 12 is "L" shape, and baffle 12 and frame 1 constitute dismantlement mounting structure, when the device is in normal use, baffle 12 can carry on spacingly to spliced pole 7, prevent that it from removing left, and the inside magnetic path 13 of spliced pole 7 and the inside magnetic path 13 of frame 1 attract each other, thereby prevent that the phenomenon that drops from appearing in baffle 12, and when needs are changed vocabulary card 11, use external force to upwards remove baffle 12 and accomplish the dismantlement to baffle 12, then remove spliced pole 7 left, take it out from the inside of support column 6, thereby change vocabulary card 11.

Fixed block 15 and screw rod 16 constitute revolution mechanic, and fixed block 15 and sucking disc 14 constitute the sliding friction structure, when fixing the device, hug closely the wall with sucking disc 14, then rotate screw rod 16 and make fixed block 15 reduce downwards to make the atmospheric pressure in the sucking disc 14 reduce, ambient pressure can suppress the device this moment, thereby make device and wall closely laminate.

The working principle is as follows: when the vocabulary contrast explanation device for college English teaching is used, firstly, the suction cup 14 is tightly attached to a wall, then the screw 16 is rotated to move downwards, and at the moment, the fixed block 15 moves downwards along with the screw, so that the air pressure in the suction cup 14 is reduced, and the outside air generates pressure on the rack 1, so that the device is tightly attached to the wall;

subsequently, the supporting rod 2 is rotated, when the supporting rod 2 rotates, the fixed gear 5 can be driven to rotate, the fixed gear 5 at the upper end can be driven to rotate, so that the 2 supporting columns 6 and the connecting column 7 rotate simultaneously, when the connecting column 7 rotates, the positions of the connecting frame 8 and the vocabulary cards 11 inside the connecting frame are changed accordingly, so that the vocabulary cards 11 are learned, after the vocabulary cards 11 are adjusted, the clamping rod 3 is moved leftwards, so that the clamping rod is installed in the fixed hole 4 in an embedded mode, and the supporting rod 2 is prevented from rotating by the fixing device;

when the needs are changed vocabulary card 11 in the device, with baffle 12 rebound, external effort is greater than the appeal between the magnetic path 13 this moment, thereby take out baffle 12, remove spliced pole 7 left again, upwards remove dead lever 9, make it no longer suppress vocabulary card 11, take out vocabulary card 11, put into the inside of link 8 with new vocabulary card 11 again, after putting into and finishing, spring 10 promotes dead lever 9 rebound, thereby fix vocabulary card 11, later with the device recovery normal position, holistic practicality has been increased.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
