The invention discloses a soil loosening device with a water sprinkling function for a garden nursery, and relates to the technical field of garden nurseries. The soil loosening device comprises a U-shaped plate; the upper surface of the U-shaped plate is fixedly connected with a fixing frame; a driving motor is fixedly installed inside the fixing frame; and an output shaft of the driving motor issleeved with a large gear. According to the soil loosening device with the water sprinkling function for the garden nursery, a screw rod I and a screw rod II are driven to rotate by positively rotating a rotating rod, and the screw rod I and the screw rod II are matched with each other through a sliding rod and a sliding sleeve in the rotating process, so that two T-shaped rods are far away fromeach other along with the movement of two nuts, and then conical columns move into cylinders and extrude arc-shaped plates, a plurality of connecting plates are driven to get away from one another, and tooth rakes are driven to move outwards, so that the length of the tooth rake is adjusted, a user can adjust the lengths of the tooth rakes according to the soil loosening device, and the device hasuniversal applicability so as to meet the use requirements of the user.

The invention belongs to the field of non-motor vehicle fittings, relates to a non-motor vehicle inner tire, and in particular relates to a non-pneumatic inner tire which particularly comprises an inner tire, wherein one side far away from the tire rim of the inner tire is arranged as a support part; the support part of a radial cross section of the inner tire is a major arc; two sides of the major arc extend inwards along a tangential direction and are integrally formed as fixed parts; the support part of the inner tire is internally hollowed; air channels are formed in the extension direction of the inner tire; a plurality of reinforcing ribs are manufactured between inner walls of the fixed parts of the inner tire at uniform internals; and a heat exchange hole is formed between every two adjacent reinforcing ribs.

The invention relates to the field of automobile safety, and discloses an automobile energy absorption device. The energy absorption device comprises a first fixed plate, a second fixed plate and an energy absorption component; the energy absorption component is a three-dimensional spiral wire-shaped plastic material; the first fixed plate is arranged at one end of the plastic material, and the second fixed plate is arranged at the other end of the plastic material; the automobile energy absorption device is arranged between a vertical beam of an automobile and a protection lever, the first fixed plate is connected to the vertical beam, and the second fixed plate is connected to the protection lever. According to the technical scheme, the three-dimensional spiral wire-shaped plastic material is adopted in the energy absorption component, and the fixed plates are arranged at the two ends of the energy absorption component. The lateral shock resistance capability of the energy absorption component is improved, the lateral crumple is not likely to occur, each area of the energy absorption component in the axial direction has the same conquassation limit, so that when the energy absorption component is under shock, uniform and regular crumple can be achieved, and the energy absorption effect of the energy absorption component is sharply improved.

The invention discloses a winch, a motor, a transmission shaft, a drum and a gear box. The drum includes: a pipe part and a connecting part; the winch also includes: a first inner bearing and a second inner bearing, and the first inner bearing and the second inner bearing The inner bearings are respectively arranged to extrude the bearing inner holes connected to the transmission shaft; the winch also includes: a first outer bearing and a second outer bearing, wherein: the inner side of the first outer bearing is extruded on the outer wall of the pipe, and the gear The fitting end of the box is pressed against the outside of the first outer bearing, the inner side of the second outer bearing is squeezed on the outer wall of the pipe part and the end edge of the opening end of the pipe part, and the fitting end of the motor is pressed against and connected to the second outer bearing. outside. The winch implementing the present invention can enhance the waterproof sealing of the motor and the gearbox, improve the performance of the equipment; enhance the connectivity of the motor, the drum and the gearbox, reduce the pressure on the motor and the gearbox, and improve efficiency.
