Detailed Description

As shown in fig. 1-3, the present embodiment includes a cap 1, two support rods 2, two connecting rods 3, two fixing rods 4, and two hoops 5. The hoop 5 is semicircular, the two hoops 5 clamp the port of the chimney 6, the two ends of the hoop 5 are provided with connecting parts, the bolt penetrates through the connecting parts of the two hoops 5 to fix the hoop 5 on the chimney 6, and the hoops 5 of one type can clamp the chimneys 6 with different calibers in a certain range. In this embodiment, a long sliding table 51 is disposed in the middle of the anchor ear 5 along the outward protruding direction, the length direction of the sliding table 51 is perpendicular to the arc surface of the anchor ear 5, a slotted hole 52 is disposed on the sliding table 51, and the length direction of the slotted hole 52 is the same as the length direction of the sliding table 51.

The cap body 1 is in a conical surface shape, two short upright posts 11 are symmetrically arranged on the inner concave surface of the cap body 1, and one ends of the two support rods 2 are respectively and rotatably connected with the two upright posts 11. In the embodiment, the rotatable connection is that one end of the support rod 2 is set to be in a step shape, the end of the upright post 11 is set to be in a step shape corresponding to the step shape, the two step-shaped ends are buckled with each other, the outer convex end face of the step-shaped end of the support rod 2 is set to be in an arc shape, the outer convex end face of the step-shaped end of the upright post 11 is also set to be in an arc shape, and then bolts penetrate through the outer convex part of the step-shaped end of the support rod 2 and the outer convex part of the step-shaped end of the upright post 11 to fix the support rod 2 and the upright post 11. When needing to adjust, only need unscrew the bolt can rotate the angle of stand 11 and bracing piece 2, when not needing to adjust, screw up the bolt can, realized the rotatable coupling of the two.

One end of each of the two connecting rods 3 is hinged with the other end of each of the two supporting rods 2, and the other end of each of the two connecting rods 3 is hinged with one end of each of the two fixing rods 4. The fixing rod 4 in this embodiment is Y-shaped, and the other end of the connecting rod 3 is inserted into the middle of the upper end fork of the fixing rod 4 and hinged to the fixing rod 4. The other end of the fixed rod 4 is provided with a thread, the other end of the fixed rod 4 penetrates through a slotted hole 52 on the sliding table 51, and then the fixed rod is screwed up by a nut 8 to realize the connection with the hoop 5. When the nut 8 is loosened, the fixing rod 4 can slide back and forth in the elongated slot 52. The structure has the adjusting function when being adapted to chimneys with different calibers and when the state of the cap body 1 is adjusted to be upright or fallen down is changed.

It should be noted that the axis of the fixing rod 4 hinged to the connecting rod 3 in this embodiment is perpendicular to the axis of the chimney 6, and this structural limitation is to ensure that the cap body 1 can avoid the opening of the chimney 6 when falling down, and can completely block the opening of the chimney 6 when standing up. The hinge axes at the two ends of the connecting rod 3 in the embodiment are perpendicular to each other, and the structural limitation is to play a role in adjusting when being matched with the hoop 5 to be suitable for chimneys with different calibers.
