The invention provides a folding frame, a displayer, a keyboard and an electric appliance. The folding frame comprises hinges and limiting structures. The hinges are connected through rotary connecting structures, and can be unfolded or folded. Each hinge of the folding frame comprises a front side face and a rear side face. The limiting structures guarantee that the front side faces of the hingesare located on the same plane when the folding frame is in an unfolded state. The rotary connecting structures comprise first rotary connecting structures and / or second rotary connecting structures.One connected hinge rotates to the front side face close to one side, and another connected hinge rotates to the rear side face close to one side. In a folded state, a circle with the minimum bendingradius of a flexible membrane can be contained between the side face of one connected hinge and the rotating axis, the side face of another connected hinge adapts to the flexible membrane, or a gap isformed between the side face of the one connected hinge and the flexible membrane. The displayer comprises the folding frame and a flexible displayer attached to the folding frame. The electric appliance comprises a circuit module, a power module and the displayer. The power module is electrically connected with the circuit module and the displayer, and the displayer is electrically connected with the circuit module. The displayer and the electric appliance can be folded and are convenient to store and carry.

A case sealing device is disclosed. The case sealing device conveys a cardboard box and simultaneously closes a flap group provided on edges of opening of the cardboard box. The case sealing device includes a folding member, a drive unit, and a control unit. The folding member contacts a flap of the flap group that extends along a conveyance direction of the cardboard box and folds the flap. The drive unit moves the folding member. The control unit controls the drive unit. In operation of folding the flap, a longitudinal direction of the folding member is inclined with respect to the conveyance direction such that the folding member contacts a front edge of the flap in the conveyance direction before other portions of the flap.

The invention relates to a ship engine material frame. The four corners of a bottom support are provided with corner columns, and movable columns are rotationally connected to the upper ends of the corner columns through connection mechanisms; a transverse beam is arranged between every two adjacent movable columns, and a slide rod is arranged between the other two movable columns opposite to the transverse beam; a first folding frame capable of being folded is arranged on the bottom support, and a second folding frame is arranged opposite to the first folding frame; the first folding frame comprises installing faces, supporting columns and a first loop bar; the installation faces are composed of two parallel first beams, one ends of the installing faces are hinged to the supporting columns through pin shafts, the other ends of the installing faces are fixed to the first loop bar, the supporting columns are installed on the bottom support through pin shafts, and the first loop bar buckles the transverse beam and is locked through positioning pins; and the second folding frame comprises a second installing face, the second installing face is a panel of which the middle is provided with a hole, the four corners of the panel are provided with supporting rods, the bottoms of the supporting rods are provided with a framework, and the supporting rods are movably connected to the bottom support through the framework. The ship engine material frame can be quickly positioned after hoisting and loading, the accuracy is good, and the truck loading efficiency is improved; in addition, the folding frames can be folded for storage, the folding process is easy and fast to operate and can be completed through one person, and the space for the return stroke is saved; and return stroke piling is reliable, and the running safety is improved.

A liquid container is provided, which comprises a container body provided as an elongated flexible bag having a closed end face at an end thereof, a pouring outlet formed at the closed end face of the container body, and a support means for preventing deformation of a side face of the container body in its front portion adjacent to the closed end face, whereby a rear portion of the container body which is not reinforced by the support means is housed into the front portion as the contained liquid is discharged, in which the liquid container further comprises a stopper which is disposed on the side face of the rear portion of the container body for engaging with the front portion of the container body, whereby after the stopper has been engaged with the front portion, portion of the rear portion in front of the stopper is prevented from being further housed into the front portion. The liquid container allows the length of the container after use to be reduced to less than one half the length before use, and furthermore even in the case where the length of the container body is long, allows the rear portion to be well housed in the front portion, for stably allowing the contained liquid to be taken out.

The invention provides a triangular cable pole hinge type foldable truss which comprises a guide rod, a folding cable, a tension cable, a plurality of truss units and a plurality of hinge rods. The truss units are triangular rigid frames. All the triangular rigid frames are sequentially connected with the guide rod from top to bottom. The triangular rigid frame at the bottommost portion is fixedly connected with the guide rod. The other triangular rigid frames arranged upwards along the guide rod are movably connected with the guide rod. The triangular rigid frames are connected through hinge rods. The folding cable sequentially penetrates through the two ends of all the triangular rigid frames from top to bottom and is fixedly connected with the triangular rigid frames at the top and at the bottom. The tension cable is sequentially penetrates through the two ends of the triangular rigid frames from top to bottom in a zigzag shape and is fixedly connected with the triangular rigid frames at the top and at the bottom. The triangular cable pole hinge type foldable truss is simple in system configuration, high in shrinking percentage and capable of stretching out and drawing out repeatedly, spacecraft space maneuvering or ontrack maintenance is facilitated, the ontrack folding requirement of a future large-scale soft solar cell array and the like can be met, and the application prospects are wide.

The invention discloses an LED lamp bracket convenient to store. The LED lamp bracket convenient to store comprises a foundation support, a lamp plate, a sliding block, connecting rods, a worm, and aworm wheel used for balance weight of the lamp bracket. A mounting cavity is formed in the foundation support. The worm is rotatably connected with the foundation support, and is close to the right end of the foundation support. The worm wheel is rotatably connected into the mounting cavity, and is engaged with the worm. A first sliding rod and a second sliding rod are respectively arranged at twoends of the worm. A rotating shaft is rotatably connected between the first sliding rod and the second sliding rod. The lamp plate is fixedly mounted at the rotating shaft. Two ends of the sliding block are respectively slidably connected with the first sliding rod and the second sliding rod. One ends of the connecting rods are hinged to the foundation support. The other ends of the connecting rods are hinged to the sliding block. A rack is arranged on the left side of the sliding block in the sliding direction of the sliding block. A gear is fixedly mounted at the rotating shaft. A locking mechanism is arranged at the sliding block. The lamp bracket is simple in structure, and is convenient to fold and store.
