The utility model relates to mechanical processing auxiliary equipment field especially, and is split type bearing shell drilling positioning frock, including split type bearing shell drilling positioning frock, including base, clamping component, and clamping mechanism includes T type clamp plate, and T type clamp plate includes connecting plate and clamp plate, and the clamp plate is located split type bearing shell mounting hole, and the bottom fixed position column of connecting plate tail end, and the base is fixed with hollow tube, and the inner chamber diameter of hollow tube is greater than the outer diameter of position column, and the hollow tube position column rotation connects, and the vertical installation adjusting screw rod on base, and the central hole is set up in connecting plate, and adjusting screw rod passes through the hole and penetrates T type clamp plate, and the adjusting screw rod is screwed adjusting nut, and adjusting nut is located T type clamp plate top. Through the matching of arc locating groove and split type bearing shell connecting lug outer arc surface, avoid the vibration when punching and cause bearing shell to shake, improve drilling processing accuracy. Compression spring can play the role of saving strength when replacing bearing shell, and the labor intensity of operating personnel is reduced.

This utility model relates to the field of transfer box technology and discloses a hollow board turnover box, comprising: a box body, which is composed of multiple hollow boards spliced ​​together, and the hollow boards have honeycomb-shaped hollow cavities inside; reinforcing columns are provided at the four corners of the box body, and the reinforcing columns are fixedly connected to the hollow boards, and the reinforcing columns also have hollow cavities inside; a groove is formed on the top of the box body; a protrusion is installed on the bottom of the box body, and the shape of the groove matches the shape of the protrusion; multiple ventilation holes are evenly formed on the side walls of the box body; and a moisture-proof net is installed in the ventilation holes. In this utility model, by setting the box body, groove, and protrusion, the honeycomb-shaped hollow cavities inside the box body ensure lightweight and high-strength support, while the embedded structure of the protrusion and groove and the design of the rubber anti-slip pad prevent lateral sliding or tipping during stacking, thereby improving the utilization rate of storage space and ensuring the stability of logistics transportation.

This application discloses a tray assembly and a child seat. The tray assembly, used in the child seat, includes a base, a tray, and an anti-slip mat. The tray is detachably connected to the base. The tray has a first wall and a second wall arranged opposite to each other. The second wall has a connecting structure, which includes a fixing post and a fixing ring. The fixing post, the fixing ring, and the second wall together define an annular space open at one end. The anti-slip mat includes a connecting part and an anti-slip part connected to each other. The connecting part is located within the annular space and has a connecting hole. The connecting hole is interference-fitted with the fixing post so that the anti-slip mat is connected to the tray. The anti-slip part is located outside the annular space and contacts the base. This design prevents the components connecting the tray and the base from detaching from the tray during the user's handling of the tray.
