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.

The utility model relates to the technical field of goods shelf price strips, in particular to a goods shelf price strip stable in installation, which comprises a clamping seat, the clamping seat comprises a vertical plate, an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are arranged at the upper end and the lower end of the vertical plate respectively and are elastic, and the length of the lower clamping plate is larger than that of the upper clamping plate. The upper clamping plate is obliquely arranged from top to bottom, the lower clamping plate is obliquely arranged from bottom to top, first fixing teeth are arranged on the inner side of the upper clamping plate, at least two second fixing teeth are arranged on the inner side of the lower clamping plate, the first fixing teeth and the second fixing teeth are bent towards the vertical plate, and an oblique panel connected with the vertical plate is arranged on one side of the vertical plate. A label storage space is formed between the inclined panel and the vertical plate, the inclined panel is obliquely arranged outwards from bottom to top, third fixing teeth are arranged on the inner side of the inclined panel, and the third fixing teeth are arranged in the direction of the vertical plate. The goods shelf is simple in structure, stable in installation, high in universality and capable of being matched with goods shelves of various specifications, and meanwhile the price labels are convenient to replace.

This utility model relates to the field of steel structure technology, specifically to a welding steel structure clamp, comprising a base, with clamps on both sides of the upper middle portion of the base, each clamp including a base plate, with a fixed clamping plate fixedly installed on one side of the upper part of each base plate, and a sliding groove formed in the middle of the upper part of each base plate, the sliding clamping plate being slidably engaged in the middle of the sliding groove, a hollow groove formed in the middle of one end of the base, a semi-circular worm gear fixedly installed on one side of the middle of the hollow groove, a semi-circular sliding groove formed in one side of the middle of one end of the base, a semi-circular sliding plate being slidably engaged in the middle of the semi-circular sliding groove, a fixed plate fixedly installed at the lower end of the semi-circular sliding plate, and a worm gear rotatably installed in the middle of one end of the fixed plate. This utility model solves the problem that traditional clamps are mostly fixed angles, such as right angles, and can only meet the needs of straight line or simple angle welding, such as flat welding and fillet welding, which have many shortcomings in practical use.
