The invention discloses a soft bouncing robot and its method for quick release and recovery of energy. A main body is arranged in the housing, and an energy storage part is arranged at one end of the main body. The energy storage part is used to convert the input mechanical energy into elastic energy for storage to realize For the jumping of the bouncing robot, the other end of the energy storage part is provided with a foot, and the other end of the main body is provided with a control center of gravity part. Tilting in a fixed direction produces a fixed take-off angle; the energy storage part is equipped with an energy collection part and an energy release part. The energy collection part is used to control the relative movement between the main body and the foot; release the elastic energy stored in the energy storage part. The invention has the advantages of compact structure, simple control, stability and reliability.

The invention discloses a mechanical adaptive shock absorber. The mechanical adaptive shock absorber comprises a screw, wherein a screw body of the screw is in sleeve joint with a spring washer, the screw body of the sleeve is in sleeve joint with a spring, the screw body of the sleeve is in sleeve joint with an acceleration induction balancing weight, the screw body of the sleeve is in sleeve joint with a compression valve plate, the screw body of the sleeve is in sleeve joint with a compression throttling valve plate and the screw body of the sleeve is in sleeve joint with a compensation valve plate. According to the mechanical adaptive shock absorber, when a vehicle is turning, the vertical motion speed of wheels is lower, the motion speed of the shock absorber is low, the vertical acceleration is lower, the spring cannot be compressed by the acceleration induction balancing weight under inertia, at the moment, the compression throttling valve plate and the compensation valve platereceive pre-tightening force from the spring and are not easily opened, so that compression damping is kept, and controllability is improved. The mechanical adaptive shock absorber is applicable to anautomobile.

The invention relates to the technical field of spraying devices, and discloses automatic spraying equipment for demoulding oil in a PC component production line, including a spray box, a panel arranged on the upper surface of the spray box, and an external connecting pipe arranged on the upper surface of the panel, and the spray box There is a placement mechanism and a braking mechanism inside, and a spray mechanism is set at the lower end of the panel. The spray mechanism is set inside the spray box through the panel, and the release oil is filled in the storage box, and the release oil will flow along the electric push rod. A enters the nozzle, and the mold release oil is sprayed by the nozzle. During the spraying process, the storage box will be connected to the panel through the threaded bolt, so that the leverage point of the nozzle is the whole spray box, which improves The stability of the nozzle during the working process prevents the nozzle from shaking during the working process, resulting in uneven spraying, and improves the spraying quality.

The invention provides a spatial rope net based on a constant force tearing belt. According to the spatial rope net, partial rope segments, such as rope segments close to the middle of an edge threadrope, of the edge thread rope of the rope net are oppositely folded and overlapped and tied by the constant force tearing belt with the specific strength, that is to say, a fine thread with the certain breaking strength is used for sewing the oppositely-folded rope, and the number of sewing stitches and the density of the stitches are determined by the tearing force strength set by a task. After the rope net is spread to a certain area, the distance between every two adjacent rope nodes tied with the constant force tearing belt is larger than a preset value, the sewing stitches of the constantforce tearing belt start to break at this moment, and further relative separation motion of the rope nodes at the two sides is blocked. After the combined effect of multiple constant force tearing belts, a net opening of the rope net is reduced, the whole rebound speed of a net body can be lowered, the longitudinal motion change of the rope net is small, the valid working time of the rope net iseffectively prolonged, and the valid working distance of the rope net is effectively lengthened.

The invention relates to the field of shoes, in particular to a shoe. The technical problem to be solved by the present invention is to provide a kind of shoes. A shoe, comprising a shoe body, a control switch, a charging port, a power supply control module and an air cushion type splash-proof mechanism; a control switch is arranged in the middle of the top of the shoe body; A power supply control module is arranged on the side. This device protects the water droplets when stepping on and lifting the feet; protects the joint between the sole and the upper from being covered by small water droplets bouncing on the surface, and soaking the joint for a long time will cause the sole and the upper to be glued The problem.

The invention provides an air cylinder, a pump body assembly and a compressor; the air cylinder comprises a cylinder body (1), a sliding piece (2) and a sliding groove (3) are arranged on the cylinderbody (1), the sliding piece (2) is arranged in the sliding groove (3) in a sliding manner, a locking part is further arranged on the cylinder body (1), when the pressure of outer gas of the air cylinder reaches the preset pressure, the locking part locks the sliding piece (2), and when the pressure of the outer portion of the air cylinder is smaller than the preset pressure, the locking of the sliding piece (2) is relieved. According to the air cylinder, the phenomenon that when the interior pressure of the compressor is too high, the compressor continuously carries out compression is avoided, and the safety protection performance of the compressor is improved.
