Sliding open grooves are formed in the periphery of the manipulator mounting plate, and the connecting pipes are located in the sliding open grooves. The micro air pump main body can slide, so that the micro air pump main body drives the positions of the connecting pipe and the adsorption disc to be adjusted, then a workpiece is extruded by the adsorption disc, the workpiece can be adsorbed by the adsorption disc through the micro air pump main body, and grabbing of the workpiece is completed; and different workpieces can be adsorbed by adjusting the position of the adsorption disc, so that the adsorption effect is better.

This utility model relates to an anti-loosening expansion bolt for asphalt pavement, comprising a threaded section, a raised section, a barb assembly, and a nut. During the actual installation of asphalt pavement guardrails, holes can be drilled in the asphalt pavement. The barb is then rotated and retracted into a receiving groove. The threaded section and raised section are then placed into the drilled hole. The nut is then rotated using a tool, causing it to engage with the ground and slowly pull the threaded section and raised section upwards. Simultaneously, the barb slowly pierces into the surrounding soil as it rises. Once the barb is fully extended, the resistance to nut rotation increases, stopping the rotation of the nut. The guardrail is then installed on top of the threaded section, thus achieving better fixation to the asphalt pavement and maintaining good grip even during hot weather, preventing the installation equipment from falling off.

The utility model relates to a thin-wall pipe fitting grabbing manipulator which comprises a supporting arm, and a connecting base is installed at the top of the supporting arm. The supporting arm comprises a top plate located at the top and two vertical plates extending downwards from the top plate, and a middle area is formed between the two vertical plates. A pair of cylinders of which the bottoms are hinged is mounted in the middle area; the middles of the pair of clamping arms are rotationally connected to the supporting ends on the two sides of the lower portion of the vertical plate correspondingly. Push rods of the pair of air cylinders are correspondingly connected to the top ends of the clamping arms respectively. Rubber chucks are respectively mounted at the lower ends of the clamping arms; the auxiliary supporting plates are connected to the outer vertical face, away from the center, of the vertical plate through connecting screws; the vertical plate is provided with a first avoiding area; according to the scheme, positioning and clamping of the thin-wall part can be achieved without too large clamping force, and the grabbing effect is greatly improved; and the device has the advantages of simplicity in manufacturing, convenience in use, no scratch on part surfaces, large adaptive pipe fitting diameter range and the like.

The utility model provides an air resistance type upper limb push-pull trainer, which belongs to the technical field of exercise rehabilitation equipment and comprises an air resistance box body and an equipment base below the air resistance box body, the air resistance box body is obliquely arranged, a support plate is arranged in the middle of the air resistance box body, a standard cylinder is arranged on the upper surface of the support plate, and a cylinder piston rod is arranged at the upper end of the standard cylinder. A connecting rod is arranged above a piston rod of the air cylinder, a push-pull handle is arranged above the connecting rod, a bearing connector is arranged behind the push-pull handle, a fan-shaped limiting stopper is arranged on one side of the bearing connector, an angle encoder is arranged on the other side of the bearing connector, a backrest is arranged in front of the air resistance box body, a cushion is arranged below the backrest, and a displayer is arranged on one side of the front end of the equipment base. A user can sit on the cushion to control the height of the seat through the air pressure rod and the adjusting handle, the push rod grip is held by hands, the connecting plate connected with the push rod grip and the connecting rod move, and the resistance needed by the user is controlled by matching the standard air cylinder with the air cylinder piston rod in a push-pull mode and the fan-shaped limiting stopper.

The application discloses a tendon-driven flexible gripper based on Miura plate folding design, which comprises a driving input module, a fixed bearing platform, a sliding platform and a Miura plate base. The driving input module is composed of a rotating disc and a transmission rope system. The rotating disc is used to drive the transmission rope system to move, and the transmission rope system is designed in a closed path. The clockwise and counterclockwise rotation of the rotating disc will respectively cause the transmission rope system to retreat and advance. The transmission rope system is connected with the sliding platform, and the two ends of the Miura plate base are respectively connected with the fixed bearing platform and the sliding platform. When the rotating disc rotates, the Miura plate base is folded or unfolded along the preset crease line, so that the state of the Miura plate base changes between clamping and flat unfolding. The soft gripper of the application is driven and controlled by a single steering engine to realize the opening and closing movement of the gripper, and the equipment quality and the driving control complexity are significantly reduced.

The utility model relates to the technical field of manipulators, and discloses a multi-specification goods and materials grabbing manipulator which comprises a frame body, a manipulator body and a manipulator body. The at least two top suction modules are installed on the frame body and arranged in the first direction, and each top suction module comprises a top suction module body and a plurality of first suction cups arranged on the bottom side of the top suction module body; the position of the at least one top suction module is adjustable in the first direction; the side suction module is installed on the frame body and located on the side, parallel to the first direction, of the peripheral side of the top suction module, and the side suction module comprises a side suction module body and at least two second suction cups arranged on the side, facing the top suction module, of the side suction module; the position of the side suction module is adjustable in the second direction and the position of the side suction module is adjustable in the third direction, the second direction is perpendicular to the first direction, and the third direction is perpendicular to the first direction and the second direction.
