At present, all mechanical disc brake mechanisms must have two clamps to clamp the brake discs synchronously to achieve the brakes. However, all designs must be assembled by The two clamps are locked to lock a clamp to the brake body. However, because the clamp is symmetric and adjacent, when one clamp is locked to the brake body, the other clamp has only a very small lock. The solid space causes inconvenience in assembly; and because the design of the small space fixture is too complicated, the thickness design of the turntable and the tilting member is limited, and the durability of the structure is not good.

The creator has the fixture structure of the conventional mechanical disc brake, and when one of the clamps is locked to the brake body, the other clamp has only a very small locking space, which is inconvenient to assemble; The idea, after many discussions and trial sample tests, and many revisions and improvements, 遂 launched this creation.

The present invention provides a clamp structure for a mechanical disc brake, wherein a clamp comprises: a turntable having a shaft portion at the outer center, and a receiving hole in the outer side of the shaft portion, the outer side of the receiving hole being provided on the outer side a retaining edge, the inner end of the shaft portion is provided with a joint portion, the joint portion is interlocked with the control rod, and the outer side of the turntable has a pushing surface; a rocking member is disposed on the pushing surface of the turntable, and the tilting member corresponds to The pushing surface is provided with a top abutting surface, a locking hole is arranged in the center, and a positioning portion for restricting rotation is arranged outside the rocking member; a coupling member is provided with a thread on one end and a restriction portion on the other end; a spring The coupling member is disposed at the one end of the spring, and the coupling member passes through the receiving hole of the rotating plate, and the screw is locked to the locking hole of the rotating member, so that the other end of the spring is topped. The interlocking structure is disposed between the pushing surface and the top abutting surface to control displacement of the turntable; and an external locking member is locked to the turntable.

The main purpose of the fixture structure of the mechanical disc brake is that the two clamps are arranged in the body group, the process is convenient, simple and fast, and the productivity can be greatly increased. The turntable and the swinging member are disposed in the set of holes. The spring is further disposed with the coupling member, and the set of holes is locked to the swinging member by the other side, that is, the assembly of the clamp is completed, and the assembly of the two clamps is independent and does not interfere with each other.

The secondary purpose of the fixture structure of the mechanical disc brake is that the design of the swaying member is a simple planar shape, and the shell-like design is eliminated, so that the structural strength is better.
