The spraying thickness is not uniform, and the dismounting cannot be carried out.

This utility model relates to the field of water conservancy engineering technology and discloses a water conservancy engineering pipeline support, including a first mounting frame and a second mounting frame. The first mounting frame is located in front of the second mounting frame. A fixed shaft is fixedly installed at the top of the first mounting frame, and a rotating frame is rotatably connected to the middle of the fixed shaft. A support shaft is fixedly installed at the left end of the inner cavity of the rotating frame, and a round pipe is fixedly installed at the right end of the inner cavity of the rotating frame. The support shaft is slidably connected inside the round pipe. This utility model achieves the ability to rotate the rotating frame by rotatably connecting the top of the first mounting frame to the fixed shaft. After the pipeline is installed, the rotating frame can be rotated to above the second mounting frame, thereby protecting both the first and second mounting frames. The support shaft and the round pipe are used for weighing, directly distributing the pressure load between the first and second mounting frames, avoiding direct pressure damage to the pipeline.

The utility model relates to the field of EPE pearl wool, in particular to an EPE pearl wool packaging structure. Comprising a box body, a box cover abuts against the upper surface of the box body, adjusting structures are arranged on the two sides of the box cover, each adjusting structure comprises a mounting groove, the mounting grooves are formed in the box cover, butt joint grooves are formed in the two sides of the box body, and a first mounting plate and a second mounting plate are slidably connected to the inner walls of the mounting grooves and located on the two sides of the box cover correspondingly; a first butt-joint plate and a second butt-joint plate abut against the positions, corresponding to the butt-joint grooves, of the two sides of the box body, and the first butt-joint plate and the second butt-joint plate are located on the two sides of the box body respectively. The EPE pearl wool packaging structure has the advantages that the supporting frame, the supporting plate and other parts are conveniently arranged in the box body and the box cover, the supporting frame and the supporting plate are used for supporting the box body and the box cover, the EPE pearl wool packaging structure can bear larger external force, articles placed in the box are prevented from being pressed and damaged, and the EPE pearl wool packaging structure is easy to disassemble and assemble and high in practicability.

The invention relates to the technical field of steel structures, in particular to an assembly type steel structure beam-column joint adopting a friction type high-strength steel joint, which comprises a steel column, and a connecting plate is arranged on the side surface of the steel column; threaded holes are symmetrically pre-formed in the upper side and the lower side of the end part of the steel beam; the friction type high-strength steel connector comprises an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are both vertically and fixedly connected to the side face of the connecting plate, and the end of the upper clamping plate and the end of the lower clamping plate are each provided with a straight notch corresponding to a threaded hole in the end of the steel beam. According to the assembly type steel structure beam-column joint adopting the friction type high-strength steel joint, a large amount of energy can be dissipated through friction slippage of a bolt connection interface under the action of an earthquake or a reciprocating load through the friction layer on the connection interface of the upper clamping plate and the lower clamping plate, so that pressure bearing damage of a bolt hole wall or shear brittle failure of a bolt is avoided; and the ductility and the energy dissipation capacity of the joint are remarkably improved, so that the anti-seismic safety of the whole structure is enhanced.

The utility model relates to the technical field of printing machines, and discloses a water-based ink temperature control device of a printing machine, which comprises an ink box, an ink groove and a printing plate roller, the input end of an ink pump is connected with the inside of the ink box, the output end of the ink pump is provided with an input pipe, and the outer surface of the input pipe is provided with two groups of static mixers; one end of the input pipe extends into the ink fountain, a connecting pipe is installed on the lower surface of the ink fountain and connected with the ink box, and a cleaning mechanism is installed on one side of the ink fountain. Due to the arrangement of the cleaning mechanism, the situation that in the prior art, the cleaning mechanism abuts against the printing plate roller all the time, abrasion is large, and damage is prone to occurring is avoided.

The utility model discloses a kind of watch small-sized parts compression fixer, including the locating adjusting assembly being installed in compression ware body interior, the detachable assembly is threadedly installed in the top of compression ware body, the locating adjusting assembly includes adjusting groove, directional rod is fixed in the adjusting groove, support column is slidably connected on the directional rod, screw rod is rotatably connected on the side surface of support column, adjusting knob is fixed in the other end of screw rod, by setting locating adjusting assembly, the position situation of the part that can be compressed according to actual needs is carried out, the axial center of corresponding clamping seat is adjusted, so that the axial center of the part to be compressed is coaxial with the axial center of compression rod, so that the axial center of the part to be compressed can be avoided in compression process with the axial center of compression rod not in coaxial, so that the compression of part is more accurate, and it can also prevent the compression damage to other parts.
