The invention discloses a refrigerator shelf component comprising a base, a moving shelf and a lifting mechanism. The moving shelf is disposed on the base in a vertically liftable manner. The lifting mechanism comprises two pairs of first rail slides and two pairs of gear rods. The two pairs of first rail slides are disposed on two sides of the base in the first direction respectively and extend in a second direction perpendicular to the first direction. The two pairs of gear rods are disposed on two sides of the moving shelf in the same direction, and a first sliding part is disposed at the lower end of each pair of gear rods. The first sliding part for each pair of gear rods locates in the corresponding pair of first rail slides. The upper ends of each pair of gear rods are provided with mutually meshing teeth, and the upper ends of each pair of gear rods area rotatably connected with the moving shelf. The refrigerator shelf component has the advantages that the height can be effectively adjusted conveniently; the gear pair is efficient in self-locking, and shedding can be prevented. In addition, the invention discloses a refrigerator comprising the refrigerator moving shelf.

To provide a floating connector wherein strengths against pull-out forces in the height direction are high and both housings are resistant to separation, the slide housing slides in any direction perpendicular to the height direction to reliably absorb the deviation in the position of the floating connector in relation to that of the counterpart connector without resulting in any defective contact with the counterpart contacts nor buckling of the contacts, the floating connector can be produced easily, and the floating connector has a high self-supportability through setting an appropriate rigidity of the contacts. It is a floating connector wherein the connecting parts of the contacts are pressed into the base housing, the contacting parts of the contacts are pressed into the slide housing, and both housings are so related to each other by means of protruding parts protruding in the width direction and grooves into which the protruding parts are inserted that both housings can slide in any directions perpendicular to the height direction.

The invention discloses full-automatic mylar adhering equipment. The full-automatic mylar adhering equipment is characterized in that a tray, a first guide wheel, a second guide wheel, a conveying plate, a first fixing frame, a first gripping device, a second gripping device and an accommodating plate are positioned on a framework, the second fixing frame is positioned on the first fixing frame, the first fixing frame and the second fixing frame can respectively linearly reciprocate along a moving direction of a belt, the first gripping device capable of longitudinally reciprocating is provided with a first sucker and pulling ejector pins, the first sucker is positioned at the fronts of the pulling ejector pins, the first sucker and the pulling ejector pins are positioned right above the front end of the conveying plate, a first fixed clamp and a second fixed clamp which are capable of clamping the belt alternately are respectively fixed onto the first fixing frame and the second fixing frame, a product positioning device is arranged on the accommodating plate, a second sucker is arranged on the second gripping device capable of linearly reciprocating in both the longitudinal direction and the horizontal direction, and a controller can control the first fixing frame, the second fixing frame, the first fixed clamp, the second fixed clamp, the first gripping device and the second gripping device to act. The full-automatic mylar adhering equipment has the advantages that the full-automatic mylar adhering equipment is accurate in mylar adhesion position, firm in adhesion and high in work efficiency, the labor cost is saved, and the quality of products is guaranteed.

The invention discloses an earphone sleeve and an earphone component. The earphone sleeve comprises a connection part and a positioning part, wherein the connection part is used for being detachably connected with an earphone, the positioning part is arranged on the connection part in a protruded manner, and the positioning part is used for being inserted into anthelix and / or antitragus of an ear,so that the earphone sleeve and the ear are positioned and matched with each other. According to the earphone sleeve provided by the invention, the structure of the earphone sleeve is improved, so that the matching of the earphone component and the ear is more stable.

The invention discloses an electric connector component. The electric connector component comprises an electric connector and a protection sleeve sleeved on the electric connector, wherein the electric connector is provided with an insulation main body and a plurality of conductive terminals arranged on the insulation main body; a groove is formed on the insulation main body; a stopping part is arranged on the insulation main body; and the stopping part is clamped and contained in the groove so that the electric connector and the protection sleeve are fixedly connected with each other. In the electric connector component, the stopping part is arranged on the inner surface of the protection sleeve, and the groove corresponding to the stopping part is formed on the electric connector; and the stopping part is contained in the groove and can only move in the groove. Compared with the matching between the conventional electric connector and the protection sleeve, the matching between the electric connector and the protection sleeve in the invention is more stable, and the protection sleeve is hard to fall off.

The invention refers to a kind of pressure makeup cotton and a manufacturing method. The character of the product structure lies in: it is made up of ultrathin surface and elastic middle layer. The surface is tiny, soft, flexible, which is pressed with special process. the middle layer has elastane, forms the elastic cotton core layer; the ultrathin surface is covered on the surface of the middle layer. The makeup cotton with soft, elastic surface can be produced through high temperature process and pressing process. The character of the process is that there adds a special dual-axle double-way pressing process.
