This utility model discloses a tightening mechanism for a boom drilling and installation robot, relating to the field of boom installation technology. It includes a limiting sleeve for boom assembly, with one end face recessed axially to a certain depth to form a limiting groove for accommodating a nut. The shape of the limiting groove matches the shape of the nut to prevent rotation and limit its movement. When the limiting sleeve is driven to rotate around its axial direction, the limiting groove restricts the nut's rotation. The limiting groove on the limiting sleeve precisely matches the nut's shape, applying radial limiting force through geometric constraints to ensure the nut remains synchronized with the limiting sleeve during rotation. Compared to the shortcomings of existing technologies where manual tightening with a wrench requires a large operating space and insufficient tightening force, this tightening structure uses a coaxial drive of the limiting sleeve, which does not occupy a large horizontal operating space and is suitable for areas with dense pipelines.

This utility model discloses a quantitative winding device for producing polymer plastic film, relating to the field of plastic film winding technology. It includes a base winding structure, a positioning structure, and a quantitative winding structure. The base is L-shaped. The winding structure includes a bearing fixedly installed on the inner wall of a through hole on the left side of the base, a rotating roller rotatably mounted on the right side of the base via the bearing, a hollow winding roller sleeved on the surface of the rotating roller, and a power component located on the left side of the base to drive the rotating roller to rotate. A cylinder combined with a conical block and a second compression spring linkage mechanism enables rapid locking and releasing of the winding roller, eliminating the need for manual tools, shortening assembly and disassembly time, and significantly improving production efficiency. Furthermore, three sets of symmetrically distributed positioning pins work in conjunction with the first compression spring to ensure a rigid connection between the hollow winding roller and the rotating roller, improving equipment operational stability.

The utility model discloses a bottle embryo injection mold with quick cooling channel relates to bottle embryo injection mold technical field, including first injection frame, second injection frame, third injection frame, fourth injection frame and positioning groove, first injection frame side sets up and draws mechanism, and the draw mechanism includes third injection frame, fifth injection frame, guide frame, guide groove and guide bolt, the guide frame fixed connection is in first injection frame side, and first injection frame side vertical fixed two L shape guide frame that is skew symmetry distribution, and the guide frame side sets up Z shape guide groove, and this structure passes through the bidirectional support of L shape guide frame and skew symmetry layout balanced draw mechanism stress, avoids the inclination jam when sliding, and the broken line track of Z shape guide groove restricts guide bolt transverse displacement, and then enhances the stability of drawing process, ensures the die opening and closing precision.
