6 results about "Volume body" patented technology

An air extraction device and a nasal aspirator. The air extraction device includes a cylinder body and a variable-volume body. The cylinder body defines a cavity and a first air hole, and the first air hole is in communication with the cavity. The variable-volume body is arranged within the cavity. The variable-volume body is configured such that, through a change in a volume of the variable-volume body within the cavity from large to small, an air pressure within the cavity is reduced, for providing a suction force externally through the first air hole.

The present invention provides a roll that can effectively mitigate the step difference caused by the starting end of the winding of a sheet and can suppress contamination. According to one aspect of the invention, a roll (10) is provided, which includes a core (11) and an elongated sheet (12) wound around the outer peripheral surface (11A) of the core (11), wherein the roll includes: a first gap (13) located between the core (11) and the first circumference of the sheet (12) and in contact with the end face (12A) of the starting end (12A) of the first circumference of the sheet (12) in the length direction (DR2); a first filling portion (14) filling the first gap (13) and extending along the width direction (DR1) of the core (11); and a first exposure suppression member (18) suppressing the exposure of the end (14A) of the first filling portion (14) in the width direction (DR1) on the outside of the sheet (12).

The utility model discloses a mooring rope packaging machine, which relates to the technical field of mooring rope packaging equipment and comprises a workbench, and a plurality of groups of sliding chutes are arranged on the upper surface of the workbench around a circle at equal angles. Bundling cable reel bodies with different diameters are placed on the upper surface of the roller, then the rotating handle is rotated by hand to drive the worm to rotate through the rotating rod, then the worm is meshed with the worm gear to rotate, the worm gear drives the first gear to rotate, and the first gear is meshed with and drives each group of second gears and third gears to rotate at the same time. A third gear rotates to be meshed with a rack so as to drive a sliding base, a connecting block and a bundling device to synchronously move, self-adaptive distance adjustment is conducted according to bundling cable coil bodies with different diameters, practicability is improved, operation is convenient and fast, and after debugging is completed, the device is convenient to operate. And then the control panel is used for simultaneously starting each group of binding devices to bind and package the binding cable coils with different diameters, so that the packaging stability of the binding cable coil body is guaranteed.

The invention relates to a roll and a roll manufacturing method. A roll (1) is provided with: a winding core (2); a long first film (10) wound around the winding core (2); and a joining member (3) that joins one end of the first film (10) in the longitudinal direction to the winding core (2). The joining member (3) is disposed between the winding core (2) and one end of the first film (10) in the longitudinal direction in the thickness direction of the first film (10). Furthermore, in the radial direction of the winding body (1), the distance from the outer peripheral surface of the winding core (2) to the radial inner side surface of one end of the first film (10) in the longitudinal direction is the shortest in at least one end in the width direction with respect to the distance in the entire region in the width direction.

A prechamber element for an igniting device has a main body and a prechamber cover. The main body and the prechamber cover form a prechamber. The main body has an opening for receiving a spark plug and has a fastening portion for arrangement in an assembly channel of a cylinder head or a cylinder head sleeve. At least one overflow passage is formed on the main body and / or on the prechamber cover. At least one outlet opening of the at least one overflow passage lies at least partially outside a volume body that is described by a geometric extrusion of a smallest cross section of the assembly channel along a longitudinal axis of the assembly channel. An igniting device has a prechamber element and a cylinder head sleeve and / or a cylinder head.
