Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1-5, the embodiment of the present invention: a kind of rolling door machine guide chain seat, including a convex seat 1, the inboard side of the convex seat 1 is a cambered surface 2, the cambered surface 2 can be laminated with the arcuate shell wall of the rolling door machine rear body and fixed, there are fixed ears 3 on the both sides of cambered surface 2 separately, the fixed ear 3 has fixed holes 4 separately; the outer side of the convex seat 1 is a plane 5, the left side and the right side of the surface of the plane 5 are respectively provided with a cross boss 6, the bosses 6 are respectively provided with a cross slot hole 7, the cross slot hole 7 is communicated with the inner side cambered surface 2 of the convex seat 1, and the inside of a slot 8 in the four directions of the cross slot hole 7 is respectively provided with a roller 9.
When the guide chain seat is used, the cambered surface 2 of the guide chain seat 1 is attached to the shell wall of the rear shell of the door rolling machine, and the fixing lugs 3 on the two sides of the guide chain seat 1 are locked and fixed through screws. During assembly, one end of the hand-pulling chain extends into the shell from one of the cross-shaped slotted holes 7 in the chain guide seat 1 and surrounds the chain groove of the hand-pulling ratchet wheel, and the hand-pulling chain surrounds the hand-pulling ratchet wheel and then extends out from the other cross-shaped slotted hole 7 of the chain guide seat 1 again. After the guide chain seat 1 is used for a period of time and the guide chain seat 1 arranged on the shell is worn, the guide chain seat 1 can be replaced after the screw is loosened. The utility model discloses convenient to use, cost of maintenance is lower, sets up gyro wheel 9 in cross slotted hole 7 moreover, and the pulling chain is more smooth and easy, increases life, reduces the potential safety hazard of rolling door machine.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
