The utility model belongs to the technical field of storage boxes, and particularly relates to a foldable storage box which comprises a main body unit, a top plate is detachably arranged on the main body unit, the main body unit comprises a bottom plate, side plates are arranged on the two sides of the bottom plate, and the bottom plate comprises a first base plate and a second base plate. The first base plate and the second base plate are oppositely folded so that the two side plates on the two sides of the bottom plate can be close to each other, the side plates are detachably connected with the top plate, and the two side plates are oppositely fixed. A supporting groove is formed in the upper portion of the side, close to the second base plate, of the first base plate, the upper side of the second base plate extends towards the first base plate to form a supporting protruding edge, the supporting protruding edge abuts against the interior of the supporting groove so that the first base plate and the second base plate can be stably unfolded, the first base plate is rotationally connected with the second base plate through a hinge rod, and the hinge rod is arranged on the lower side of the supporting groove. The supporting protruding edge can turn over towards the upper portion of the supporting groove and enables the first base plate and the second base plate to be folded oppositely. The foldable storage box is stable in structure and long in service life.

The utility model provides a steel transportation protection device, which belongs to the technical field of transportation equipment and comprises a transportation protection front plate, a transportation protection frame and a bottom frame fixed on a transportation vehicle, the transportation protection front plate is fixed at the front end of the bottom frame, the transportation protection frame is rotatably connected to the rear end of the bottom frame, and the transportation protection frame comprises a transportation protection rear plate, a stabilizing rod and a shaft sleeve. The transportation protection rear plate and the stabilizing rods are fixedly connected with the shaft sleeves respectively, the shaft sleeves are rotationally connected with the bottom frame, guide plates are inserted into the transportation protection front plate and the transportation protection rear plate respectively, and the bottom frame is inserted into the side edge of the transportation vehicle through the multiple protection rods. Through the cooperation of the bottom frame, the transportation protection frame and the plurality of protection rods, steel products are protected from the front, the back, the left and the right of the transportation vehicle, and the steel products are effectively prevented from protruding forwards and backwards or inclining laterally; and the protection effect of the transportation protection rear plate of the transportation protection frame and the multiple protection rods inserted into the bottom frame on the steel is enhanced.

The invention relates to the technical field of flooring, and discloses a groove-type rubber flooring, comprising a flooring body, wherein an outer wall surface of the flooring body is provided with a groove, two rows of grooves are provided inside the flooring body and an inner sleeve is fixedly connected in the groove, front and rear inner walls of the inner sleeve are both fixedly connected with a fixed cylinder, movable grooves are provided at positions corresponding to the fixed cylinder on the front and rear sides of the flooring body, a pressure pad is fixedly connected to the outer wall surface of the movable groove, the thickness of the pressure pad is adapted to the groove depth of the movable groove, and a plurality of boosting pads are fixedly connected to the inner wall surface of the groove. Through the arrangement of the pressure pads, during the installation of the flooring, the pressure pads at the position in contact with the ground are compressed by force to cause the boosting pads to expand, and after the boosting pads are inflated and expanded, they fill in the gap between the buckle and the groove and apply pressure to the buckle, thereby greatly increasing the friction between the buckle and the groove, and increasing the stability of the connection between the buckle and the flooring.

The utility model relates to a bra structure with traceless cups, which is characterized in that the bra structure comprises two traceless cups and two first side wings, each traceless cup comprises light cloth, shaping gauze and lining which are sequentially stacked together from inside to outside, and the two traceless cups are arranged side by side left and right; the two first side wings are respectively connected with the outer side edges of the two traceless cups, and the upper ends of the first side wings extend upwards and are bent towards the middle parts of the traceless cups to form first beltloops. Compared with the prior art, the bra cups have extremely high stability, can not deform after being used for a long time, and are very attractive and comfortable after being worn for a long time, so that the service life of the bra can be prolonged, the replacement frequency of the bra can be reduced, and the use cost of a user can be further reduced; and the bra structure can also play a very good role in covering and limiting the auxiliary breasts, so that the bra is very attractive and comfortable to wear.

The utility model belongs to the technical field of storage boxes, and particularly relates to a storage box which comprises a main body unit, a top plate is detachably arranged on the main body unit, the main body unit comprises a bottom plate and side plates arranged on the two sides of the bottom plate, the side plates and the bottom plate can be folded and drawn close to each other, and the bottom plate and the side plates are provided with connecting protrusions and connecting grooves respectively. The connecting protrusions and the connecting grooves are matched to enable the bottom plate and the side plates to be movably connected and prevent the bottom plate from being separated from the side plates, first inserting parts are arranged on the two sides of the bottom plate respectively, first inserting holes matched with the first inserting parts are formed in the side faces of the side plates, and the first inserting parts and the first inserting holes are matched to limit relative folding of the side plates and the bottom plate. The side plates can move towards the two sides of the bottom plate and enable the first inserting parts to be separated from the first inserting holes; the side plates are detachably connected with the top plate respectively, the side plates are limited to move towards the two sides of the bottom plate, and therefore the first inserting parts are kept connected with the first inserting holes, and the storage box is stable in structure and long in service life.

This invention discloses a footrest mechanism and a sofa: It includes a footrest support frame connected to a leg support frame via a multi-link mechanism. The leg support frame has a folded position and an extended position, while the footrest support frame has a folded position close to the leg support frame and a supporting position away from the leg support frame. When the leg support frame is in the folded position, the footrest support frame can rotate 85-95 degrees from the folded position to the first supporting position; when the leg support frame is in the extended position, the footrest support frame can rotate 170-185 degrees from the folded position to the second supporting position. Because the sofa uses the aforementioned footrest support frame, when the leg support frame is rotated upwards to a reclining position, the footrest can further adjust according to the user's leg posture, thereby providing better support for the user's feet.
