4results about How to "Guaranteed rotational flexibility" patented technology

The invention discloses a connector embedded type ocean pipe, belongs to the technical field of ocean pipelines, and is used for being sequentially connected and vertically extending to the deep position of the seabed. The pipeline comprises a pipeline body, joint embedded sections are arranged at the upper end and the lower end of the pipeline body, a plurality of embedded grooves spaced in the circumferential direction are formed in the outer end faces of the joint embedded sections, and internal thread sleeve pieces are arranged in the embedded grooves; the end face of the embedded section of the connector is further provided with a plurality of mounting hole sites located between the adjacent embedded grooves, and external thread screws are rotationally connected into the mounting hole sites and extend out of the end face of the pipeline body. And when adjacent pipeline main bodies are connected, the external thread screw of any pipeline main body is in threaded connection with the internal thread sleeve of the other pipeline main body, so that the end surfaces of the embedded sections of the two joints are hermetically attached. According to the scheme, through the embedded threaded connection structure, no flange needs to be exposed, the connection sealing performance and the corrosion resistance are improved, the submarine complex service environment is adapted, and the pipeline connection reliability and the structural stability are guaranteed.

The utility model belongs to civil construction equipment technical field especially relates to a civil construction support device, including base, the base is located in the side of wall, the other side of base is equipped with hinged member through welding, the hinged member is swingingly connected through connecting rod, the other side of hinged member swingingly installs support rod, the bottom of support rod swingingly installs on support base, the bottom fixed mounting of support base has rubber damping pad. This civil construction support device, hinged mechanism is combined with lock nut, spring pre -tensioning half -spherical pre -tightening spare through stud, realizes hinged ball ± 15 DEG rotation and mechanical self -locking, and the tensile force is more than 200kN, improves installation efficiency, and the support mechanism is with the structure of sleeve, realizes the regulation of ± 1mm accuracy with hydraulic cylinder and laser range finder, the bottom is designed to adapt to the inclined ground, hot-dip galvanizing and fluorocarbon coating prolong the life, solve the many problems of traditional device.

The utility model discloses a kind of component feeders of SMT chip mounter, including support, transverse moving mechanism, slide, reel and vertical plate, taper jack is opened in slide, taper jack is coaxially arranged with the hole on reel, and the same plug-in sleeve is inserted, one end of plug-in sleeve is open, the other end is closed, the one end of closed state is slidably connected with cylinder, the utility model in the quick locking mechanism of plug-in sleeve, ball and tapered column composition is used, when installing reel, only need to insert plug-in sleeve into reel center hole and the taper jack of slide, under the action of first spring, tapered column will ball eject, clamping in taper jack, while ring is pressed reel, complete fixed, when disassembling, only need to press finger pressure block, make tapered column back off by overcoming the elasticity of first spring, ball can retract, to easily pull out plug-in sleeve and reel, this process does not need any tool, can be completed in several seconds, greatly improve the efficiency of replacement.

The utility model belongs to the technical field of locking devices, and particularly relates to a rotating shaft locking device which comprises a rotating shaft, a self-locking disc is rotationally installed on the rotating shaft, an annular groove is formed in one side of the self-locking disc, and a first pressing disc is installed in the annular groove. A first pressing disc groove is formed in the side, provided with the annular groove, of the first pressing disc, a second pressing disc is installed in the first pressing disc groove, a special-shaped disc is further arranged in the annular groove of the self-locking disc and rotationally connected with the rotating shaft, a compression spring is arranged on the special-shaped disc, and the compression spring is connected with the self-locking disc. Stand columns are mounted at two ends of the compression spring. The self-locking disc and the special-shaped disc can be locked at fixed positions and unlocked, so that the position of the medical manipulator part connected to the self-locking disc and the special-shaped disc is effectively locked, position deviation of the medical manipulator part caused by external interference is avoided, the operation precision of the medical manipulator is effectively guaranteed, and the operation accident rate is reduced.
