Problems solved by technology

[0002] At present, in the civil air defense door locking device, the transmission rod is relied on for power transmission, and the transmission rod is connected with other parts by the connecting rod head. Usually, one end of the connecting rod head is cylindrical with internal thread, and the other end is a pin hole or The single plate or double plate of the bolt hole is assembled with the transmission rod and becomes one. The transmission rod will rotate to a certain extent during the long-distance transmission process, which will drive the connecting rod head to rotate together, causing wear and tear on the connecting rod head and the other end of the connecting piece. Affects the flexibility of the drive

Embodiment Construction

[0009] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0010] A fixed-rotation connecting rod head for civil air defense doors, including a piece connecting part 1 and a rod connecting part 2. The piece connecting part 1 is a long board with a through hole, and the rod connecting part 2 is an inner part connected with a transmission rod. Threaded hollow cylinder structure, one side of the cylinder structure has a plane 3, and a cylindrical rod body 4 is arranged on the plane 3, the connecting rod head connects the transmission rod and parts to realize power transmission, the plane of the rod connecting part 2 3. In contact with the door panel of the civil air defense door, the cylindrical rod body 4 extends into a specific groove on the door panel surface. The cylindrical rod body 4 is restricted...

Abstract

The invention relates to a constant-rotating connection rod head of a civil air defense door. The constant-rotating connection rod head of the civil air defense door comprises a rod connecting portion and a part connecting portion, so that a rod body and a part are connected, and power driving is achieved. The constant-rotating connection rod head of the civil air defense door is characterized in that the side, making contact with a door panel, of the rod connecting portion is provided with a plane where the cylindrical rod body is arranged, the cylindrical rod body is located in a specific track slot in the door panel, and the connection rod head is limited from rotating in the axial direction of the rod body. Thus, abrasion between the part connecting portion and the part is reduced, and driving resistance is reduced.

Description

technical field [0001] The invention belongs to the field of civil air defense doors, in particular to a fixed-rotation connecting rod head for civil air defense doors. Background technique [0002] At present, in the civil air defense door locking device, the transmission rod is relied on for power transmission, and the transmission rod is connected with other parts by the connecting rod head. Usually, one end of the connecting rod head is cylindrical with internal thread, and the other end is a pin hole or The single plate or double plate of the bolt hole is assembled with the transmission rod and becomes one. The transmission rod will rotate to a certain extent during the long-distance transmission process, which will drive the connecting rod head to rotate together, causing wear and tear on the connecting rod head and the other end of the connecting piece. Affect the flexibility of the transmission. Contents of the invention [0003] The purpose of the present inventi...
