The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Shown in Fig. 1 to Fig. 4 B, the utility model has disclosed a kind of top structure of tent frame, and it comprises a pin joint seat 1, and at least three tent poles 2 are that example describes to sentence four tent poles 2; Corresponding each tent pole 2 is formed with pivot connected slot 11 on this pin joint seat 1; Each tent pole 2 is to utilize the end of tent pole 2 to be articulated in the pivot connected slot 11 of above-mentioned pin joint seat 1 after being nested with a spring 3 respectively and being placed through a sleeve 4.

The bottom of 11 liang of auricles 12 of described pin joint seat 1 each pivot connected slot is to form arcwall face, and on two auricles 12 pivoted hole 121 apart from the distance of auricle 12 outer ends less than the distance of pivoted hole 121 apart from auricle 12 lower ends.

The external diameter of described sleeve 4 is the width greater than above-mentioned pivot connected slot 11, and its front end forms necking down 41 and lean for an end of spring 3, and the internal diameter of necking down 41 is the external diameters greater than tent pole 2.
