A round steel pipe truss structure assembly type connecting joint is characterized in that: web members and chord members are connected through hoops, the hoops are respectively provided with clamping grooves with the same diameter as the chord members and the web members, the circumferences of the clamping grooves are respectively smaller than the circumferences of the corresponding chord members and web members, and the connection of the hoops with the chord members and the web members is respectively realized through tightening of high-strength bolts. The round steel pipe truss structure can be a planar truss structure or a space truss structure, the chord members are round steel pipes, the web members are round steels or round steel pipes, the chord members are linear or curved according to the shape of the truss, the web members are bent to realize direction change and keep continuous at the joint, and the continuousness of the web members at the joint is one of the characteristics of the structure.

The utility model discloses a novel simple and easy research and study loom, including weaving shaft, heald frame, reed, cloth roller and fixed pin shaft, weaving shaft is located weaving loom's last side, and is provided with roller shaft above, heald frame sets up weaving shaft's front side, reed sets up heald frame's front side, cloth roller sets up reed's front side, and one end of cloth roller is below the fixed block that is provided with, and the shaft hole that is opened in the one end surface of cloth roller is also set up on the fixed block, and the shaft hole is also set up on the fixed block, and the fixed pin shaft embedded in the shaft hole through setting, makes the fixed effect of cloth roller formation above the fixed block. The simple and easy research and study loom can effectively prevent the rotation of the cloth roller through the fixed pin shaft, avoid the problem of secondary winding, the transition and guiding function is formed through the setting roller shaft, reduces the failure rate of heald frame, improves its weaving efficiency, reduces the overall volume, is used for research and study only, is easy to understand and learn.

This invention provides a frame-type subframe structure. It features left front and left center body mounting points on the left longitudinal beam, and right front and right center body mounting points on the right longitudinal beam. A reinforcing plate is positioned between the two lower plates. Left and right rear body mounting points are symmetrically positioned on the two lower plates. The subframe is connected to the vehicle body at six points, connecting the body and suspension, and improving body rigidity. The front subframe also supports the engine, air conditioning compressor, and transmission. The full-frame subframe absorbs some of the impact force during a frontal collision, effectively solving the subframe-body connection problem. Over long-term use, it prevents tearing due to stress concentration and repeated fatigue.
