AI Technical Summary
During outdoor study activities, students find it difficult to effectively shade the sun in strong sunlight. Existing parasols or hats will affect the operation of their hands or heads, and the shade area may be small or cause the head to be stuffy.
A study and activity backpack with its own sunshade structure is designed. The backpack is equipped with a telescopic groove and a sunshade mechanism. The sunshade mechanism consists of a first lifting rod, an angle rod, a second lifting rod and a sunshade cloth. Through the cooperation of these components, the sunshade cloth can be quickly expanded and the sunshade angle can be adjusted through the adjustment of the angle rod.
It provides effective sunshade effect without affecting students' hand operation, while ensuring the breathability of students' heads, avoiding the stuffy problem caused by insufficient sunshade.

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-Figure 4 As shown, the utility model provides a study and activity backpack with a built-in sunshade structure, including a back body 1, side bags 2 are fixedly installed on both sides of the back body 1, two shoulder straps 3 are fixedly installed on the rear end of the back body 1, shoulder straps 3 are also fixedly installed on both sides of the back body 1, a telescopic groove 5 is opened in the fixed seat 4, a sunshade mechanism 6 is provided between the two fixed seats 4, the sunshade mechanism 6 includes two first lifting rods 7, angle rods 8 are movably installed on the upper ends of the two first lifting rods 7, second lifting rods 9 are movably installed in the two angle rods 8, and a sunshade cloth 10 is fixedly connected between the two second lifting rods 9 and the two angle rods 8.
[0022] The first lifting rod 7 is inserted and installed in the telescopic slot 5, and the outer side of the first lifting rod 7 and the inner side of the telescopic slot 5 are provided with damping. The first lifting rod 7 is inserted and installed in the telescopic slot 5 of the fixing seat 4, and the entire sunshade mechanism 6 can be stored to the upper end position of the back body 1. A storage slot 11 is provided at the upper end of the first lifting rod 7, and an insertion through slot 12 is provided on one side of the storage slot 11. A slot 18 is provided at the bottom of the storage slot 11. Rotation slots 13 are provided at the upper positions on both sides of the storage slot 11. Rubber blocks are fixedly installed on both sides of the rotation slot 13, and an extrusion channel is formed between the two rubber blocks. A plurality of limiting slots 14 are also provided on the inner side of the rotation slot 13. The storage slot 11 provided in the first lifting rod 7 can provide installation and telescopic conditions for the angle rod 8, and the inner side of the storage slot 11 located at the bottom of the limiting slot 14 has a channel, which is conducive to the angle rod 8 being stored in the storage slot 11, and the rotating block 15 passes through the rubber blocks on both sides of the limiting slot 14 to the lower position of the inner side of the storage slot 11;
[0023] A rotating block 15 is fixedly installed at the lower position on both sides of the angle rod 8, and a plurality of limiting teeth 16 are fixedly installed on one side of the rotating block 15. The rotating block 15 is rotatably installed in the corresponding rotating groove 13, and the limiting teeth 16 are clamped in the corresponding limiting groove 14. The angle rod 8 rotates in the storage groove 11 with the two rotating blocks 15 as the axis, and the angle between the second lifting rod 9 and the sunshade cloth 10 can be adjusted.
