4results about How to "Sufficient gripping force" patented technology

The application discloses a portable adjustable pipe supporting and carrying trolley, and belongs to the technical field of carrying trolleys. The trolley comprises a trolley frame, two running wheels and a gripping handle. The two running wheels are respectively arranged on the two sides of the trolley frame. The gripping handle is arranged on the middle part of the trolley frame. An extension part is fixedly arranged on the top of the trolley frame. A center rod is fixedly arranged on the top of the extension part. Pipe tongs are rotatably connected to the two ends of the center rod. A working cavity is arranged between the center rod and the extension part. A rotating handle is movably arranged on the side wall of the extension part. A placing groove is arranged on the side wall of the extension part. A rotating mechanism for driving the two pipe tongs is arranged in the working cavity. The pipe tongs clamping and the trolley carrying are combined, portable clamping and carrying of pipes with different diameters are realized, the labor intensity is effectively reduced, and the pipe carrying efficiency and safety are improved.

The application provides a feeding structure and a spring machine, and belongs to the technical field of spring production. The feeding structure comprises a feeding assembly and a straightening assembly. The feeding assembly comprises a fixed plate, a connecting plate, a bidirectional screw rod, a moving block, a conveying wheel, a rotating shaft, a motor, a first bevel gear and a second bevel gear. The connecting plate is arranged at the bottom of the fixed plate. The straightening assembly comprises a supporting plate and a straightening wheel. The supporting plate is fixedly connected to the fixed plate. By arranging the fixed plate, the connecting plate, the bidirectional screw rod, the moving block, the conveying wheel, the rotating shaft, the motor, the first bevel gear and the second bevel gear, the interval of the two conveying wheels can be synchronously adjusted, the two conveying wheels can have sufficient clamping force on the wire, and the two conveying wheels can synchronously rotate to feed the wire, so that the feeding is not slippery, the center position of the feeding is unchanged, and the wire can be straightened through the arrangement of the supporting plate and the straightening wheel.

The application discloses an ambient backlight, which comprises a clamping assembly and a backlight unit. The clamping assembly comprises a vertically movable lifting part and two clamping parts. The lifting part is connected with the two clamping parts perpendicularly through a transmission part. When the clamping assembly is hung on a display support arm and moves under the action of gravity, the lifting part is pushed upward by the support arm, and the lifting part drives the two clamping parts to move close to each other in the transverse direction through the transmission part, so that the clamping assembly is fixed on the support arm of the display. When the clamping assembly is separated from the support arm, the lifting part is reset to move downward, and the lifting part drives the two clamping parts to move away from each other in the transverse direction through the transmission part, so that the clamping of the display support arm is released. The backlight unit is arranged at the back of the display, and the backlight unit is connected with the clamping assembly in the transverse direction through a preset lamp group connecting piece, so that the backlight unit makes a fixed-axis up-down flipping motion relative to the clamping assembly.
