This utility model discloses a fastener for fixing automotive wiring harnesses, including a base plate. A cover plate is rotatably connected to one side of the top of the base plate. The base plate and the cover plate are connected by a quick-release fastener. The top of the base plate has several equally spaced lower slots. The base plate is a hollow structure. An installation port is formed on each lower slot. A pressing component is installed within the installation port. The pressing component includes an elliptical pressing block located within the installation port. An insertion hole is formed at an eccentric position on the elliptical pressing block, and an adjusting rod is provided within the insertion hole. An installation hole is formed on the outer wall of the installation port, and a first threaded sleeve is fixed within the installation hole. This utility model enables the arrangement of wires and allows for independent pressing and fixing of each wire. The longer elliptical pressing block provides a larger pressing area, avoiding excessive pressing force that could damage the wiring harness due to localized small-area pressing, thus achieving stability and preventing pulling.

The utility model relates to the technical field of pipe fitting sealing connection, and discloses a sealed and fixed threaded type clamp flange structure which is used for sealing and connecting pipelines and comprises a clamp pipeline assembly, a threaded type clamp fixing ring and a sealing backing ring. The clamp pipeline assembly is provided with an inner taper annular face, the threaded clamp fixing ring is provided with a V-shaped taper annular face and a thread, and the end of the clamp pipeline assembly is provided with a thread matched with the thread. The sealing backing ring is provided with a taper annular face matched with the inner taper annular face. And the hoop pipeline assembly is in threaded connection with the threaded type hoop fixing ring through threads. According to the sealed and fixed threaded type clamp flange structure, the inner face and the outer face of the flange connector are designed to be the taper annular faces, the extrusion area of the clamp assembly and the flange connector is increased, stress concentration is reduced, and it can be guaranteed that the flange connector and the sealing ring are effectively meshed together; the sealing performance of the pipeline is ensured.

This invention belongs to the field of cigarette manufacturing technology and discloses a sealing forming device and cigarette production equipment. The sealing forming device includes a mounting frame, a first pushing mechanism, a smoke exhaust frame, and a pressurizing mechanism. The smoke exhaust frame is mounted on the mounting frame and forms a smoke exhaust channel extending along a first direction within the smoke exhaust frame. The smoke exhaust channel has a smoke inlet on one side in a second direction. The first pushing mechanism is used to push the cigarette pack located at the feeding position of the cigarette pack along the second direction. The pressurizing mechanism includes a rotary drive, a connecting arm, and a pressing arm. The rotary drive is connected to the lower side of the mounting frame. The pressurizing arm is connected to the connecting arm at an angle and passes through the smoke exhaust channel. The rotary drive can drive the connecting arm to rotate about the first direction as an axis. At least a portion of the end of the pressurizing arm is correspondingly positioned with the feeding position of the cigarette pack in the second direction and can abut against the top of the seal. The sealing forming device and cigarette production equipment produce cigarette packs with a high seal qualification rate, improving the appearance consistency of the products.
