In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-6, the present invention provides a technical solution:

a student schoolbag reflecting light at night comprises a backpack body 1, universal wheels are movably connected to the bottom of the backpack body 1, plastic boxes 3 are fixedly connected to two sides of the backpack body 1, telescopic shoulder straps 2 are connected to the backpack body 1, a light reflecting device 6 is arranged on one side of the backpack body 1, and a lifting device 5 is arranged on a contraction device 4; the lifting device 5 comprises a pull rod 51, two movable rods 53 are fixedly connected to the pull rod 51, a user can directly upwards pull the pull rod 51, the whole schoolbag is practical in a lifting mode, the bottom of the backpack body 1 is provided with universal wheels, the user can directly place the schoolbag on a plane at the moment, the whole schoolbag is pulled in a universal wheel rolling mode, the problem that the schoolbag is too heavy due to the fact that the schoolbag is converted into a lifting mode in a strap type is solved, and the condition that shoulders of a student are damaged due to long-time back holding of the shoulders is solved. A fixed block 52 is slidably connected to the surface of the movable rod 53, and the fixed block 52 is fixedly disposed on the first sliding plate 402. Two illuminating lamps 10 are movably connected to the pull rod 51. The arranged illuminating lamp 10 can provide the illuminating effect for students at night without street lamps, and the students can walk at night conveniently. And the user can use the schoolbag in a mode of directly carrying the schoolbag or pulling the schoolbag without holding the schoolbag by the hand of the user.

In this embodiment, the reflector 6 includes the reflector 61 and the reflector 63, and the reflector 61 and the reflector 63 are both connected to the backpack body 1, and the reflector 63 is located above the reflector 61, and the reflector 63 is connected with the brace 62, and the reflector 63 is fixedly mounted with a magic tape. Meanwhile, when the schoolbag is used under the condition of road at night, the light reflecting sheet 61 at the back of the schoolbag reflects light after being irradiated by light, and at the moment, the warning is given to warn passers in front of passers.

Further, be connected with folding rain hat 7 on pull rod 51, and folding rain hat 7 is the cloth material of adoption to roll up when establishing on pull rod 51, in rainwater weather, the user is when the braces schoolbag, the student opens folding rain hat 7 this moment, and is whole to wear rain hat at user's head, alright in order to realize rainproof effect, unusual convenient, be provided with folding groove 8 and the groove 9 of stepping down on knapsack body 1, and folding groove 8 is located folding rain hat 7 and pull rod 51's below respectively with the groove 9 of stepping down.

Furthermore, the contracting device 4 comprises a first sliding plate 402, the first sliding plate 402 is in meshing transmission with a second sliding plate 407 through an intermediate gear 401, and the first sliding plate 402 and the second sliding plate 407 can be relatively driven to move relatively through the rotation of the intermediate gear 401, one is to increase the pulling length of the pull rod 51 to facilitate the use, and the second sliding plate 407 moves downwards to drive two moving wheels 409 to extend to contact with the ground, so that the ground of the schoolbag can form a certain height, and the contact of dust and rainwater can be avoided. Intermediate gear 401 rotates to be connected in plastic box 3, and equal sliding connection has T shaped plate 403 to control first slide 402 and second slide 407's moving direction through the T shaped plate 403 that sets up on first slide 402 and the second slide 407 for two slides can only slide from top to bottom, and the pivoted condition can not appear, guarantees the stability of removing. T shaped plate 403 fixed connection is in the inside of plastics case 3, the bottom fixedly connected with contact plate 404 of T shaped plate 403, the contact plate 404 that sets up is just for when two remove wheels 409 shrink and reset, merge, reduce the space that two remove the wheel 409 and occupy, the bottom fixedly connected with connecting plate 406 of second slide 407, connecting plate 406 is located between two contact plates 404, it is connected with two rotating turret 405 to rotate on the connecting plate 406, and two rotating turret 405 pass through connecting spring 408 fixed connection, will provide the buffering that removes in removing the wheel 409 use through the connecting spring 408 that sets up, it has removal wheel 409 to rotate on rotating turret 405.

In addition, a bolt 411 is slidably connected to the plastic box 3, a plurality of bolt holes 410 are formed in the first sliding plate 402, and the surface of the bolt 411 is clamped in the bolt holes 410. After the first sliding plate 402 is pulled to a certain length, the bolt 411 is inserted into the bolt hole 410 at the position to fix the moving position, and at this time, the user pulls the whole schoolbag, because the length of the moving wheel 409 is long enough to keep the schoolbag at a certain height with the ground, the situation that the schoolbag holds the bottom cannot occur.

The utility model discloses a student is with schoolbag of reflection of light night when using, when the inside overweight of whole schoolbag, the user can directly upwards stimulate pull rod 51, it is practical to adopt the mode of carrying and drawing whole schoolbag, and knapsack body 1's bottom is provided with the universal wheel, the user can directly place the schoolbag at the plane this moment, adopt the rolling mode of universal wheel to stimulate whole schoolbag, the schoolbag overweight is solved to the schoolbag mode of turning into the lift-draw formula with the braces formula, the impaired condition of shoulder that the long-time back of the shoulder of student caused, use convenience of customers comes with this. Simultaneously probably forget the condition of taking the umbrella at rainwater weather student, at folding rain hat 7 on pulling pull rod 51 surface this moment, the user alright in order to unpack it apart, because rainwater weather, the schoolbag just can not adopt the mode of lift-draw formula to use, but adopts the braces formula to use, and the student will fold rain hat 7 and open this moment, wears the rain hat at user's head, alright in order to realize rain-proof effect, unusual convenient. Meanwhile, when the schoolbag is used under the condition of road at night, the light reflecting sheet 61 at the back of the schoolbag reflects light after being irradiated by light, and at the moment, the warning is given to warn passers in front of passers. In the lifting process, the situation of uneven road conditions may occur, at this time, the bottom supporting situation of the bottom of the schoolbag can be caused in the pulling process of the bottom universal wheel of the backpack body 1, at this time, the pull rod 51 can be continuously pulled, the pull rod 51 can drive the movable rod 53 and the first sliding plate 402 to move upwards while being elongated, in the moving process of the first sliding plate 402, the second sliding plate 407 can be driven to move downwards through the meshing action of the intermediate gear 401, the connecting plate 406 is fixed on the second sliding plate 407, the connecting plate 406 can be driven to move downwards at this time, the two movable wheels 409 connected to the connecting plate 406 extend out, after the backpack body is pulled to a certain length, the bolt 411 is inserted into the bolt hole 410 at the position to fix the moving position, at this time, the user can pull the whole schoolbag again, because the length of the movable wheels 409 is long enough, the situation of supporting the bottom of the schoolbag cannot occur, and the damage of the schoolbag is avoided.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
