Referring to fig. 1-4, a storage device for english teaching aids, comprising a storage box body 1, walking wheels 2 fixedly connected to four corners of the bottom of the storage box body 1, fixed blocks 3 extending from front to back and fixedly connected to the left and right sides of the storage box body 1, a stabilizing plate 4 disposed below the fixed blocks 3, a groove 5 disposed in the center of the bottom of the fixed blocks 3, lifting assemblies 6 disposed in the grooves 5, the bottoms of the lifting assemblies 6 respectively connected to the stabilizing plate 4, a plug-in cylinder 7 fixedly connected to the left side of the storage box body 1, a plug-in rod 8 disposed in the plug-in cylinder 7, slots 9 disposed on the right side of the plug-in rod 8 and equidistantly arranged from top to bottom, a movable slot 10 communicated with the plug-in cylinder 7 disposed above the left side of the storage box body 1, and a position-limiting assembly 11 disposed in the movable slot 10, the limiting component 11 is inserted into one of the slots 9, and the top end of the insertion rod 8 is fixedly connected with a push rod 12 above the insertion cylinder 7.

This scheme is when needs carry containing box body 1, through fixed block 3, mutually supporting of recess 5 and lifting unit 6 can rise and separate with stable board 4 with ground, again according to user's high demand with inserted bar 8 and push rod 12 highly rise to suitable position, and mutually support through spacing subassembly 11 and slot 9 carries on spacingly to inserted bar 8, drive walking wheel 2 through the power of exerting the promotion to push rod 12 at last and move, thereby realize portable's advantage.

Specifically, the lifting assembly 6 comprises a supporting rod 61, the top end of the supporting rod 61 is located inside the groove 5, the bottom end of the supporting rod 61 is fixedly connected with the top of the stabilizing plate 4, a thread groove 62 is formed in the top end of the supporting rod 61, a threaded rod 63 is connected in the thread groove 62 in a threaded manner, the top end of the threaded rod 63 penetrates through the groove 5 and extends to the upper side of the stabilizing plate 4, a knob is fixedly connected to the top end of the threaded rod 63, guide blocks 64 are fixedly connected to the upper sides of the left side and the right side of the supporting rod 61, guide grooves 65 are formed in the left side and the right side of the inner wall of the groove 5;

the design of this structure, it rotates to drive threaded rod 63 through applying the pivoted power to the knob, and through guide block 64 and guide way 65 restriction, make and threaded rod 63 go up and down in recess 5 through threaded groove 62 threaded connection's bracing piece 61, and drive stable board 4 and go up and down, stable board 4 can descend and support when not needing to remove containing box body 1, thereby guarantee containing box body 1's stability, as long as with stable board 4 rise can when needs remove containing box body 1, and is easy to operate.

Specifically, the top of stable board 4 just is located the equal fixedly connected with gag lever post 13 around bracing piece 61, spacing hole 14 has been seted up to two gag lever posts 13 of the bottom correspondence of two fixed blocks 3, the top of two gag lever posts 13 extends to respectively in two spacing holes 14 with the interior roof contact in spacing hole 14, two gag lever posts 13 highly all are higher than bracing piece 61, the design of this structure can be in the in-process that stable board 4 goes up and down through gag lever post 13 and spacing hole 14 set up the stability that increases stable board 4, the situation that gag lever post 13 takes place and spacing hole 14 separation can be avoided in the design of gag lever post 13 high bracing piece 61 simultaneously.

Specifically, the limiting component 11 includes a limiting block 111 horizontally disposed in the movable slot 10, the left end of the limiting block 111 is inserted into one of the slots 9, the top of the right side of the limiting block 111 is fixedly connected with a pull rod 112, the top of the storage box body 1 is provided with a horizontally disposed movable port 113, the movable port 113 is adapted to the pull rod 112, the top end of the pull rod 112 extends to the upper side of the storage box body 1 through the movable port 113, the right side of the limiting block 111 is fixedly connected with a return spring 114, the right end of the return spring 114 is fixedly connected with the inner wall of the right side of the movable slot 10, when the height of the insertion rod 8 needs to be adjusted, the return spring 114 is pulled rightward to compress and deform the return spring 114, the limiting block 111 moves leftward and is separated from the slot 9, after the position of the insertion rod 8 is determined, the force applied to the pull rod 112 is cancelled, the return spring 114 resets and drives the limiting block 111 to reset, thereby realizing the limit of the inserted link 8.

Specifically, equal fixedly connected with locating lever 15 around the diapire of push rod 12 and being located inserted bar 8 all alternates on two locating levers 15 and is provided with rather than sliding connection's locating piece 16, two locating pieces 16's right side all with containing box body 1's left side fixed connection, two locating lever 15's the equal fixedly connected with dog in bottom, can play spacing and guide effect to push rod 12 through locating lever 15, locating piece 16 and the mutually supporting of dog.

Specifically, the cover is equipped with two antiskid cover on the push rod 12, through the comfort level between the multiplicable user hand of antiskid cover and the push rod 12, the top fixedly connected with slipmat 17 of stabilizing plate 4, through the frictional force between slipmat 17 multiplicable stabilizing plate 4 and the ground for the effect of placing of stabilizing plate 4 is better.

The working principle is as follows: when the containing box body 1 needs to be carried, firstly, the knob is rotated instantaneously to enable the threaded rod 63 to rotate, and the supporting rod 61 in threaded connection with the threaded rod 63 through the threaded groove 62 is limited by the guide block 64 and the guide groove 65, the supporting rod 61 is enabled to ascend in the groove 5 and drive the stabilizing plate 4 to ascend and be separated from the ground, then the heights of the inserting rod 8 and the push rod 12 are ascended to proper positions according to the height requirements of users, and then the limiting block 111 in the limiting component 11 is inserted into the other inserting groove 9, so that the limiting of the inserting rod 8 is realized, and finally, the walking wheel 2 is driven to move by applying pushing force to the push rod 12, so that the advantage of convenience in carrying is realized;

when not needing to carry the transportation, through accomodating inserted bar 8 in section of thick bamboo 7 for push rod 12 resets, and anticlockwise rotation threaded rod 63 again makes bracing piece 61 descend, and drive steady board 4 and slipmat 17 with the ground contact can, thereby guarantee containing box body 1's stability.

The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
