Embodiment Construction

[0110] In the different figures, parts that are identical or correspond to one another are always provided with the same reference symbols and are therefore generally only described once below.

[0111] figure 1 A first embodiment of a helical part 1 according to the invention is shown. Such a screw part has a base body 2 on which a thread 3 is provided. Said base body 2 has the configuration of a hollow cylinder with a longitudinal axis identified with the reference X-X. figure 1The shown screw part 1 is in particular a nut, that is to say a component with a rotationally symmetrical cross section, in particular with a circular or at least partially circular cross section. The base body 2 of the screw part 1 is in particular a molded part which can be produced in an injection molding process, according to the invention, after the injection molding of the base body 2 is completed, at least one second part is subsequently injected. The matrix 2 of the molded part can be produ...

Abstract

The invention relates to a screw component (1) such as screw, bolt, bushing, pipe plug, and pipe connector. The said screw component has screw (3) on the basal body (2) and circumferential seals (10, 11, 100, 200 and 300) such as O-ring and / or screw safety device (6, 10, 11, 16, 60 and 300). When the said screw safety device (6, 10, 11, 16, 60 and 300) provides screwed connection between screw component (1) and another component (8), unscrew torque (ML) of screw component (1) is improved. In order to create such a screw component (1) that can guarantee long-time high reliable screw connection with another component (8) with low process costs, the said basal body (2) and the said circumferential seals (10, 11, 100, 200 and 300) are connected to each other by means of injection moulding a multiple of parts made of different polymers.

Description

technical field [0001] The invention relates to a threaded part, such as a screw, nut, sleeve, pipe plug, pipe connector, etc., having a thread on a base body and at least one circumferential seal (e.g. an O-ring) and / or at least A thread lock that increases the unscrewing torque of the screw part when there is a screw connection between the screw part and another component. Background technique [0002] Such thread safety devices for screws or screw parts are known. For example, in a known safety device of the aforementioned type marketed under the product name Klemm-tight (registered trademark), a recess is milled into the thread of the screw base, and an energy-capable locking device is pressed into the recess. Elastically deformed thread. In particular, wires consisting of a carbon fiber core with a plastic sheath are used here. Such a thread increases the unscrewing torque of the helical part when the helical part forms a screw connection with another component. Cir...
