A portable rebound (or deflecting) sports training device having at least a first rebound panel or surface adapted to rebound a ball away from the device, and a support structure adapted to hold the panel in a first, operational condition in which the panel is held generally upright; the panel and the support structure having a second, transport or storage, configuration relative to each other such that the panel and support structure lie flatter (or generally flat) relative to each other in the direction transverse to the rebound panel such that the device occupies less space.

The invention relates to a construction waste steel bar reprocessing device. The construction waste steel bar reprocessing device effectively solves the problems related to steel bar daubing cement, rust removal and the like; the technical proposal is to include a shell, wherein the left side of the shell is provided with a steel bar propelling device and a guide cylinder, a sleeve which is coaxial with the guide cylinder and can rotate is arranged inside the shell, a planetary gear set is arranged at the left end of the sleeve in a sleeved mode, the outer gear ring of the planetary gear set is fixedly connected with the shell, and a sun gear of the planetary gear set is arranged on the sleeve in a sleeved mode; the sleeve can drive the sun wheel to rotate, a plurality of sector-shaped rust removal brushes are uniformly distributed on the circumference of each planetary gear of the planetary gear set, a water storage tank which is positioned on the right side of the planetary gear setis fixedly arranged inside the shell, the right end of the sleeve is not in contact with and is arranged inside the water storage tank, the plurality of radial connecting rods are uniformly distributed on the circumference of the right end of the sleeve, and the other end of the connecting rods are connected with a scraper. The construction waste steel bar reprocessing device is not only convenient for rust removal but also conducive to coating cement.

The invention relates to the technical field of pipe processing equipment and discloses anticorrosive paint spraying and grinding equipment for production and processing of a buried pipe. The anticorrosive paint spraying and grinding equipment comprises a machine table; supporting legs are fixedly installed at the bottom end of the machine table; fixing rods are fixedly installed at the top end ofthe machine table; the top ends of the fixing rods are fixedly connected with a horizontal plate; a transmission machine is placed on the horizontal plate; the middle part of the transmission machineis fixedly provided with a fixed point grinder in a sleeving manner; a component positioned at the side surface of the fixed point grinder is fixedly installed inside the transmission machine; movingwheels are arranged at the bottom end of the transmission machine; and the moving wheels are matched with fixing grooves which are formed in the top of the horizontal plate. According to the anticorrosive paint spraying and grinding equipment for production and processing of the buried pipe, a transmission driven plate is moved toward a direction corresponding to a screw handle by twisting the screw handle so that two externally connected rods are used for driving two contact plates to expand; by regulating the radian of the two contact plates, material pipes which are different in diameter can be conveniently supported and positioned; and a bearing frame device is used for auxiliary support for the position, thereby effectively guaranteeing processing of the material pipes which are different in length.
