The utility model relates to a tire production equipment field, concretely relates to a sine wave type nylon fiber cord pendulum machine head, including main body frame, press roll frame, upper press roll, lower press roll and pendulum module. The press roll frame is connected with the main body frame, and the upper and lower press rolls are parallel and set up in the press roll frame in the upper and lower correspondence, the pendulum module is established on the main body frame, can be close or far from the press roll frame, and it contains bottom plate, wire arranging module, motor fixing frame, motor, concave-convex wheel and drive rod. When the motor drives the concave-convex wheel to rotate, the sliding unit slides along the oval sliding groove, drives the wire arranging module to reciprocate along the parallel direction with the upper press roll axis. The structure is matched by the above, overcomes the nylon line physical characteristic limit, accurately arranges the sine wave type, compared with the traditional straight line type structure, can more effectively disperse the stress, significantly improves the anti-puncture performance of the anti-puncture layer rubber sheet, and enhances the aviation tire safety protection ability.

The utility model discloses a kind of arrangement and positioning tool for hydraulic control hose of blowout preventer set, including bottom plate and movable cover plate, bottom plate and movable cover plate one end are hinged, bottom plate and movable cover plate other end detachably connect, bottom plate is equipped with multiple pipe placing groove for placing hydraulic control hose of blowout preventer set.The utility model is simple structure, easy to operate, can effectively fix and classify arrangement to multiple hydraulic control hoses, can improve installation and maintenance efficiency, and can guarantee the security, stability and aesthetic property of hose in running process.

The utility model relates to ginger planting technical field especially is a kind of ginger planting soil loosening device, including support, located the both sides of the support are provided with vice frame, and its bottom are all fixedly connected with several soil loosening parts, and the support with the vice frame between still be connected through folding mechanism;Wherein, located the both sides of the support and the tail end of the vice frame are all provided with flat part through adjusting assembly, the adjusting assembly is used to adjust the compacting degree between the flat part and soil surface, the flat part is used to level the soil surface after loosening, through the mode of rotating threaded sleeve and tightening two sides first screw rod, folding two sides vice frame is on one hand convenient to store vice frame and avoid occupying too large parking space, on the other hand, through unfolding use, it can speed up soil loosening efficiency, through the drive of adjusting assembly, the compacting degree of soil loosening part and soil surface after loosening can be adjusted, so that flat part better flattens on soft or hard soil.

The utility model belongs to the technical field of inspection equipment, and particularly relates to a self-rescuer air tightness inspection tester which comprises a barrel, a gland is arranged on the barrel and can be pressed by a pressing beam, one end of the pressing beam is hinged with the barrel, the other end of the pressing beam is provided with channel iron, a screw rod is arranged on the side wall of the barrel and corresponds to the channel iron, one end of the screw rod is hinged with the barrel, and the other end of the screw rod is provided with a nut. The screw rod can be clamped into the channel iron, the other end of the screw rod is provided with a hand wheel, the hand wheel is in threaded connection with the screw rod, and the hand wheel can be screwed deeply along the screw rod so as to press the channel iron; a vertical guide rod is arranged in the center of the top face of the gland, a sleeve is arranged in the middle of the pressing beam, the guide rod penetrates through the sleeve, a pressure protection spring wound on the guide rod is arranged between the sleeve and the gland, and scales are arranged on the guide rod. And through the design of the screw rod and the hand wheel, the pressing force of the pressing beam on the gland can be conveniently adjusted, so that the sealing performance between the gland and the barrel body is ensured.
