The invention relates to a shuttle for a mining trolley and belongs to the mining field. The shuttle comprises a main body, wherein the main body comprises a touch plate and a bottom plate; the touch plate is perpendicularly fixed on the bottom plate to enable the main body to be T-shaped; a transparent rope penetrating groove is formed in the middle of the main body and takes a wedge-shape structure with the opening gradually reduced from the bottom plate to the touch plate; a groove is formed in the groove side on one side of the rope penetrating groove; the end, close to the bottom plate, of the groove is an opening end, and the other end of the groove is a blind end; a wedge block capable of sliding in the rope penetrating groove is mounted in the groove; and a plurality of fixing holes are formed in the bottom plate on two sides of the touch plate. A self-locking function is added for the shuttle, so that on one hand, the shuttle can share part of tensile force of a steel wire rope, and on the other hand, the steel wire rope does not slide in the shuttle due to the self-locking function even if a rope fastening device has an accident or is damaged, as a result, a shuttle car does not slide to realize a protection function.

The invention relates to a spherical universal joint for an external bone fixator and a regulating type bionic external bone fixator. The spherical universal joint for the external bone fixator comprises a spherical head, a sleeve, a sleeve cover, a ball slot, a ball bowl, a locking shaft and a locking slide block, wherein the spherical head comprises a joint ball and a threaded type spherical universal joint connector A arranged on the joint ball, the joint ball is arranged on the inner side of the sleeve, the side of the joint ball close to the threaded type spherical universal joint connector A is contacted with the arc-shaped surface of the sleeve, the threaded type spherical universal joint connector A extends out of one end of the sleeve, the sleeve cover is fixedly connected with the other end of the sleeve, the outer side face of the sleeve cover is provided with a threaded type spherical universal joint connector B, and the inner side face of the sleeve cover is provided with a groove for arrangement of the locking slide block. The regulating type bionic external bone fixator with the spherical universal joint has the advantages of simple structure, light weight, low cost, regulating capability and flexible operation, and targeted and personalized combination and regulation can be realized.

The invention relates to an axial buckling and pressing connector. The axial buckling and pressing connector comprises an intra-pipe glue layer, a framework layer and an extra-pipe glue layer which are all of cylindrical structures and are sequentially connected in a sleeved manner from inside to outside to form a pipe body; the intra-pipe glue layer and the framework layer extend out of the pipe body from the same end, and the framework layer is made of flexible materials; the buckling and pressing connector further comprises an outer pressing ring and an inner pressing ring, the front end of the extending-out end of the intra-pipe glue layer is sleeved with the outer pressing ring, and the back section of the framework layer is sleeved with the inner pressing ring; and the outer pressing ring, the front section of the framework layer, the inner pressing ring and a piston flange are sequentially pressed in a butting manner from the extending-out end to the other end in the axial direction of the pipe body and are integrally molded through vulcanization. Compared with a flexible connecting pipe with the same length, a connecting structure adopting the connector and the pipe body is characterized in that the connector size is small, the flexibility section of the pipe body is long, the structure is simple, installation is flexible, and the connector and the pipe body are more firmly combined through vulcanization integrated molding. The technical problems that a traditional axial buckling and pressing connector is low in connecting strength, poor in pulling and dropping resistance and free of the self-locking function are solved.
