The combined spliced bag is simple in structure, and the use space can be combined at will to meet various travel demands of people.

The invention provides an electric oven. The electric oven comprises a shell component, a supporting surface for placing food as well as a heating element, wherein, the shell component is equipped with a door component which can be opened and closed from the front and / or rear side; the door component, the supporting surface and the shell component jointly form an arc heating chamber; the arc heating chamber comprises a cylinder, a circular truncated cone, a spherical table, an arc surface or any combination thereof; the supporting surface is arranged at the middle or bottom part of the arc heating chamber and is a plane; and the door component comprises a front door body and a rear door body. The electric oven has the beneficial effects that the door component which can be opened and closed from the front and / or rear side is added to the shell component so that the structure of the oven is changed from the traditional square shape into a circular arc shape so as to obtain unique and novel appearance; meanwhile the practical use volume is increased, and the roasting situation of the food in the heating chamber can be clearly observed; and a heat-collecting cover can uniformly reflect radiant heat from an upper heating body and a lower heating body to various parts of the heating chamber so as to ensure even heat in the heating chamber and improve the barbecuing efficiency and quality of the food.

The invention provides a refrigerator waterway system and a refrigerator provided with the waterway system. The refrigerator waterway system comprises a filter arranged at the upstream of the waterway system, a water storage kettle which is connected with the filter and is arranged at the downstream of the filter, and a water valve which is connected with the water storage kettle and is arranged at the downstream of the water storage kettle, wherein the filter, the water storage kettle and the water valve are fixedly arranged on a door body of the refrigerator. According to the refrigerator waterway system, all major structures are arranged in the door body of the refrigerator, and all key parts of the refrigerator waterway system including the water valve, the water filter, the water storage kettle and the like are arranged on the door body of the refrigerator, so that the structure of the waterway system is simplified, the connection length between a waterway and a water pipe is shortened, and the occupation for the internal structural space of a refrigerator body is reduced while the functions of the refrigerator waterway are realized; and therefore, the use volume of the refrigerator can be increased.

The invention discloses a material spray pipe moving device used for spraying the surface of a glass fiber reinforced plastic mold, which comprises a circular tubular material pipe and an angle adjustment assembly and a height adjustment assembly sheathed on its outside, the angle adjustment assembly includes an upper plate, a top Ring, gear cylinder, standpipe, rod seat, worm, lower plate, transmission column and angle motor, the height adjustment assembly includes a triangular screw, a height motor and a limit cylinder, and an upper middle hole is opened in the middle of the upper plate, The upper plate is provided with four upper holes distributed in a rectangular array, the side wall of the upper plate is provided with upper wall holes, the lower plate is located directly below the upper plate, and the middle part of the lower plate is provided with a lower middle hole. There are three lower edge holes arranged in an annular array on the outer side of the lower middle hole, and two pairs of seat threaded holes are arranged on the upper surface of the lower plate. The spray pipe moving device used for spraying the surface of the glass fiber reinforced plastic mold can replace the Z-axis and the main shaft rotating assembly of the existing automatic spraying machine, and is suitable for popularization and use.

A bouncing mechanism of a car trunk comprises arch hinges, installation base boards and torsion rod springs. The left side and the right side inside the car trunk are respectively provided with one arch hinge, one installation base board and one torsion rod spring, and the two arc hinges, the two installation base boards and the two torsion rod springs are respectively arranged symmetrically and are identical in structure. One end of an arch arm of each arch hinge is hinged to the corresponding installation base board, each installation base board is installed on a lateral rail assembly, and the other end of each installation base board is hinged to a trunk cover. The inner end of each torsion rod spring is fixed to the corresponding installation base board and the outer end of each torsion rod spring is fixed to a clamping groove of a lateral rail inner board at the same side. Each arch arm is further hinged to a torsion spring connecting rod, the middle of each torsion rod spring is clamped with the corresponding torsion spring connecting rod, a fixing installation point at each inner end, a fixing point at the corresponding outer end and a clamping point of the middle of the corresponding torsion rod spring are not on the same line, and therefore it is guaranteed that a four-bar linkage mechanism is formed. According to the bouncing mechanism, the structure and the installation position of each torsion rod spring are changed and the torsion rod springs are arranged at the left side and the right side of the trunk instead of transversely penetrating through the trunk and then being fixed. The bouncing mechanism has the advantages of being simple and practical in structure, stable and reliable in performance, low in cost and weight and capable of being widely applied to a car trunk system with an arch hinge torsion rod spring mechanism.

The invention relates to a slide rail component and a refrigerator object holding box component and a refrigerator having the slide rail component. In particular, the invention provides the slide rail component for a refrigerator object holding box. The slide rail component comprises only one roller way extending in the longitudinal direction and defined by a first ball groove and a second ball groove oppositely formed in a first vertical side surface and a second vertical side surface, and multiple balls arranged in the roller way at intervals in a rolling manner. In addition, the invention further provides the refrigerator object holding box component and the refrigerator having the slide rail component. As the slide rail component only has one roller way, the component number of the slide rail component is largely decreased, and the volume of the slide rail component is prominently reduced.
