Detailed Description

The invention is further explained in detail and given in the following description and the attached drawings.

As shown in fig. 1 to 7, the top brace contraction structure of a double-layer top tent of the present invention is mainly used for contracting and expanding a small top of the double-layer top tent, and the structure specifically includes a tent brace 1, a brace mounting seat 2, a tent brace 3, a brace mounting seat 4, a brace 5 and a brace 6, wherein the top end of the brace 6 is fixedly disposed on the top brace mounting seat 4, one end of the tent brace 3 is hinged to the brace mounting seat 4, the brace mounting seat 2 is sleeved on the brace 6, one end of the tent brace 1 is hinged to the brace mounting seat 2, and two ends of the brace 5 are respectively hinged to the tent brace 1 and the tent brace 3, so as to facilitate the product to be folded and unfolded, and in order to change the defect that the small top structure of the existing traditional double-layer top tent is fixed and cannot be independently contracted, the brace 6 and the brace mounting seat 2 are provided with contraction structures for contracting the top.

The contraction structure specifically includes reset spring 7, go up lock seat 8, lock seat 9 down, play beans 10, reset spring 7 cup joints and sets up on the pull rod 6 between top vaulting pole mount pad 4 and vaulting pole mount pad 2, plays beans 10 and passes through connecting piece 11 setting on pull rod 6, locks seat 8 and vaulting pole mount pad 2 fixed connection, lock seat 9 down with lock seat 8 and peg graft the setting, go up lock seat 8 and be provided with the play beans slide mechanism that supplies to play beans 10 and reciprocate in the lock seat 9 down. This play beans slide mechanism stretches out piece 13 including setting up in the inside first piece 12 and the second that stretches out of lock seat 9 inside under of last lock seat 8, and the first lower extreme that stretches out piece 12 extends to lock seat 9 inside down, and the second stretches out the upper end of piece 13 and extends to lock seat 8 inside, and first piece 12 and the second of stretching out stretches out piece 13 cross arrangement, and first piece 12 and the second of stretching out stretches out the gap formation between the piece 13 and plays beans slide 14.

Wherein, first piece 12 of stretching out is provided with two, and the symmetry sets up in the inside of last lock seat 8, and the lower extreme of first piece 12 of stretching out is provided with the arc structure 15 of indent, and the second stretches out being provided with two of piece 13, and the symmetry sets up in the inside of lock seat 9 down, and the lower extreme both sides that the second stretches out piece 13 are provided with arc wall 16 along the inner wall of lock seat 9 down, and first piece 12 of stretching out forms W type bullet beans slide with the second stretches out piece 13 after alternately setting up. In order to connect the components such as the hand ring or the lifting rope, a pull rod seat 17 is arranged at the lower end of the pull rod 6, so that the pull rod 6 can be pulled conveniently.

In the retracting process, firstly, the pull rod seat 17 is pulled to be pulled downwards, the pull rod 6 moves downwards under the action of the pull rod, the elastic beans 10 move downwards in the elastic bean slide way 14 along with the pull rod 6 and move to the arc-shaped grooves 16 extending from the two ends of the second extending block 13 at the lowest end of the elastic bean slide way 14, at the moment, the pull rod seat 17 is loosened, the elastic beans 10 rise for a short distance along the short edges of the arc-shaped grooves 16 in the elastic bean slide way 14 and are blocked by the short edges of the arc-shaped grooves 16, so that the small top is in a retracting state under the action of the pull rod 6, at the moment, the return spring 7 is in a compression state, when the small top needs to be opened again, the pull rod seat 17 is pulled downwards, the elastic beans 10 are loosened after being separated from the inclined short edges of the arc-shaped grooves 16, the elastic beans are in contact with the force exerted on the return spring 7, and the elastic beans 10 rise to the end of the elastic bean slide way 14 under the action of the return spring force of the return spring 7, so that the pull rod 6 is driven to rise, and the small top of the small top is unfolded.
