The utility model discloses an anti-rotation petroleum valve, which belongs to the technical field of valves, and has the technical key points that the anti-rotation petroleum valve comprises a valve body, the valve body comprises a valve body, a valve cover, a valve seat, a valve plate and a valve rod, the top of the valve body is fixedly connected with a shell, the valve rod penetrates through the shell, the top of the shell is provided with a groove, and the valve cover is arranged in the groove. According to the valve, due to the fact that the inserting groove and the inserting block are arranged, the problem of valve autorotation caused by valve design or external factors is effectively solved, the stability of valve operation is remarkably improved, and the valve is convenient to use. And the telescopic rod and the limiting block are arranged, the amplification effect of the lever principle is utilized, large enough force is easily transmitted, the valve can be successfully started, and therefore the physical strength of workers is greatly saved.

The utility model discloses a sliding type rain-proof shed for hanging basket construction. The sliding type rain-proof shed comprises a supporting system, a shielding ceiling and an automatic control sliding system. The supporting system is composed of two sets of supporting frameworks arranged in parallel, and each set of supporting frameworks is composed of a structural frame composed of two right triangles. The two right triangles have a common right-angle side which is vertically arranged; a right triangle structure frame is arranged on a hanging basket construction poured beam section, the right-angle side is transversely arranged on the poured beam section, and an automatic control sliding system is arranged at the bottom of the right triangle structure frame. The other right triangle structure frame is arranged above the outer hanging basket of the poured beam section in a suspended mode, and the right-angle side is transversely arranged above the hanging basket and covers and shields the ceiling. And the self-control sliding system is composed of at least two groups of driving rollers at the bottom of each group of supporting frameworks. The rain-proof shed adopts a combined triangular structure frame, is stable and reliable in structure, is arranged on a poured beam section in hanging basket construction, and can automatically move integrally along with a hanging basket through a self-control pulley system, so that the construction is more convenient and safer.

The utility model discloses a low bath ratio high temperature high pressure dyeing machine relates to dyeing machine technical field, the utility model discloses a dyeing cylinder body and set up at the bottom end of dyeing cylinder body's chassis and set up between the both sides of dyeing cylinder body top cloth guide pipe still include: heat shield, set up at the outside of dyeing cylinder body, the utility model discloses through heat shield blocks the heat and spreads outward through cylinder body outer wall, avoids a large amount of heat energy waste, and still can avoid workshop temperature rise, guarantees the work efficiency and safety of staff, and in through heat exchange coil absorbs the heat that cylinder spreads outward and is blocked by heat shield, through heat conduction filler can ensure that heat shield and dyeing cylinder body between heat distribution is even, avoids the position temperature difference of being close to and being far from heat exchange coil too big influence structural strength to further safe and effective utilization dyeing machine work when the heat that cylinder loses, improves energy utilization, makes equipment run more environmental protection.

The utility model relates to the field of living beef cattle egg collection, and discloses a living cattle egg collection fixing frame which comprises a top frame and a bottom frame which are arranged in parallel, the top frame and the bottom frame are both of a hollow structure, a plurality of side pipes are fixedly connected to the two sides of the bottom end of the top frame and the two sides of the top end of the bottom frame respectively, and rotating rods are rotationally installed on the front sides of the top frame and the bottom frame respectively. The top ends and the bottom ends of the sides, close to each other, of the two rotating rods are fixedly connected with transverse rods correspondingly, a plurality of vertical pipes are arranged between the two transverse rods arranged in parallel in the vertical direction in parallel, a plurality of mounting bases are fixedly connected to the top end of one side of the top frame, and one side of each mounting base is rotationally connected with a connecting bent arm through a rotating shaft. Inclined plug pins distributed in the vertical direction are fixedly installed at the positions, close to the centers of the two rotating rods, of the connecting bent arms, plug bushes matched with the inclined plug pins in an inserted mode are fixedly installed on the outer side and the inner side of the top frame correspondingly, and adjusting assemblies are movably installed on the inner sides of the ends, close to each other, of the top frame and the bottom frame. By means of the structure, the cattle can be conveniently fixed in the process of collecting the eggs of the living cattle.

The utility model relates to the technical field of textile processing, and provides a bundling tool which comprises a clamping assembly, and the clamping assembly is provided with a clamping gap used for clamping a plurality of tows. The two ends of the clamping assembly are respectively an open end for each tow to enter the clamping gap and a closed end for preventing the tows in the clamping gap from being separated from the clamping assembly. The bundling device has the beneficial effect of reducing the bundling time.

The utility model discloses a marine enhanced grinding wheel with a built-in anti-explosion fiber mesh, which relates to the field of grinding wheel devices and comprises a grinding wheel body, a grinding surface is arranged on the outer surface of the grinding wheel body, mounting blocks are mounted at the centers of the front surface and the rear surface of the grinding wheel body, mounting holes are formed in the centers of the mounting blocks, and the mounting holes are communicated with the grinding wheel body. And a repairing liquid groove is formed in the mounting block, a second wedge-shaped block is mounted on one side of the interior of the repairing liquid groove, a first wedge-shaped block is mounted on the other side of the interior of the repairing liquid groove, and holes are formed in the first wedge-shaped block and the second wedge-shaped block. By means of the repair liquid groove and the heat dissipation groove, efficient heat dissipation is achieved, meanwhile, the grinding wheel can be self-repaired, repair liquid can be recycled after the grinding wheel is used, the use cost is saved, and the safety of the grinding wheel in the use process is improved through the double anti-explosion design.
