The utility model discloses a connecting structure and lighting equipment, and belongs to the technical field of lamps, the cross section of a first mounting hole in a first mounting part is polygonal, a self-tapping screw can be tapped into the first mounting hole, and the projection of a thread top of the self-tapping screw on the cross section of the first mounting hole intersects at least three edges of the polygon. The degree of freedom of the self-tapping screw in the first mounting hole is limited, so that the self-tapping screw is stably connected with the first mounting part; the vertex of the polygon is located outside the projection of the crest of the self-tapping screw on the cross section of the first mounting hole, chippings, cut off when the self-tapping screw is tapped into the first mounting hole, of the hole wall of the first mounting hole can be stored in the corners of the polygon, tapping of the self-tapping screw is smoother, the chippings stored in the corners of the polygon can further reinforce the first mounting hole, and the service life of the first mounting hole is prolonged. The connection stability is improved.

The utility model discloses a support frame for a transfer pipette, which comprises a support frame component main body, a support plate is arranged on the side surface of the support frame component main body, a threaded rod is inserted into the inner ring surface of the support plate in a limiting manner, and a nut is sleeved on the outer ring surface of the threaded rod in a limiting manner. A fixing block is fixedly connected to the surface of the side edge of the nut. According to the device, when a user needs to use and store a transfer pipette, the user enables a mounting plate to be close to a wall where the transfer pipette needs to be mounted, then the user needs to insert a self-tapping screw into a mounting opening, then the user needs to shift a limiting plate, and then the user can open a protective door along a hinge through an arranged grip; therefore, a user can pull the storage shell, and then the user can insert the arranged pipette main body into the storage opening formed in the storage plate, so that the user can use and store the pipette.

This invention discloses a method for implementing a wideband, high-gain, dynamically tuned antenna using a reusable PCB mounting screw, comprising a screw and a PCB. The screw is a self-tapping or non-self-tapping screw made of conductive material. The PCB has screw holes, the walls of which are metallized by electroplating to form a metallization layer. A microstrip feed line is provided on the PCB, extending to the vicinity of the screw holes. Several dielectric filling slots are circumferentially arranged on the metallization layer along the hole walls. The dielectric filling slots extend axially along the screw holes and form discontinuous metallization sections on the hole wall surface. Each dielectric filling slot is filled with a dielectric material with an adjustable dielectric constant. The microstrip feed line includes a main feed line segment and an auxiliary feed line segment. The end of the main feed line segment is connected to the metallization layer of the screw holes through direct contact or electromagnetic coupling. The auxiliary feed line segment is arranged around the screw holes and forms a preset phase difference with the main feed line segment.

The utility model relates to building decoration technical field discloses a kind of skeleton line modeling's fabricated background wall, including plate body, the inside of plate body is equipped with multiple evenly distributed aluminium profile, the inside thread connection of one side of aluminium profile has fixed screw, the outer wall sliding connection of fixed screw has clamp, the outer wall sliding connection of clamp has keel, the inside sliding connection of keel has self-tapping screw, the inside upper and lower sides of clamp are evenly provided with fixed component, and the fixed component includes two moving plate. Through the cooperation of leveling structure and standardized clamp and keel slot being set on keel, installer can quickly fix keel on wall surface, and accurately adjust keel position through leveling structure, ensure installation accuracy. Clamp can make single board module quickly, accurately installed on keel, without complex on-site measurement and repeated adjustment, greatly improve installation efficiency.

This invention discloses a multi-unit automatic self-tapping screw fastening production line, comprising a frame, a circulating conveying system, a feeding unit, a CCD vision positioning unit, and at least one fastening unit. The fastening unit includes a fastening drive mechanism and a fastening execution mechanism. The fastening execution mechanism includes a guide preload mechanism, an axial floating mechanism, and a bit assembly. The guide preload mechanism is used for screw centering and workpiece preload. The axial floating mechanism employs a nonlinear variable stiffness elastomer to dynamically adjust the axial feed force. The control system controls the motion path based on CCD vision positioning, synchronously collects torque and displacement data, constructs the fastening quality characteristic parameter K = dT / dS, and determines the fastening state in real time through a torque-displacement weighted fusion index Q, achieving stripped threads and floating lock identification. The production line also includes multi-unit dynamic task scheduling, bit wear detection and life prediction, adaptive parameter adjustment, and a remote monitoring and traceability platform. This invention improves fastening quality and production efficiency.
