Elastic collision type sealed electric plug

The invention discloses an elastic collision type sealed electric plug, and aims to solve the problem that the existing air plug is powered on by means of pin connection, a female head is contacted with a male head by a tubular piece which is separated into two valves, thus the elasticity is relatively week, when the plug is plugged for many times, poor contact is caused, and the poor contact is random. The invention designs a novel elastic collision type sealed electric plug which is supported by a spring and the end face is contacted and conducted (especially a round end face is contacted and conducted). The electric plug is composed of a fixed plug and a movable plug; and contact devices of the fixed plug and the movable plug carry out reliable surface contact under the counterforce of a compression spring to complete a conductive function. In the elastic collision type sealed electric plug provided by the invention, the movable plug adopts the compression spring to support a touch head; when the fixed plug and the movable plug are connected and tightened, a part of the touch head beyond the contact end face of a moveable guide sleeve is inserted to a round hole of a fixed plug pin, and a cylindrical end face of the touch head is contacted with the bottom surface of the round hole of the fixed plug pin.

Weaving method of high-temperature-resistant composite material container pre-woven body

ActiveCN113481654AUniform weaving densityImprove mechanical propertiesKnittingYarnEngineering
The invention discloses a weaving method of a high-temperature-resistant composite material container pre-woven body. The weaving method comprises the following steps of weaving by using a knitting and three-dimensional weaving mode, adding an independent yarn while performing radial and circumferential four-step three-dimensional weaving, and knitting the yarn for a circle in the circumferential direction by using a knitting mode, so that three-dimensional weaving and knitting are carried out alternately. After a certain length is woven, the arrangement position of a yarn carrier is expanded outwards according to a certain rule, three-dimensional weaving and knitting are carried out after expansion, finally, the diameter of the woven fabric is gradually expanded to form a container, and knitting yarn is used for edge sealing. The method ensures that the whole container pre-woven body does not have any defects of faults, different gap sizes and the like, the circumferential knitting yarns ensure that the container pre-woven body can bear relatively large internal pressure, and the structural stability is ensured; and the integrally woven and formed container is uniform in weaving density, free of defects such as faults and good in mechanical property, and the weaving method is suitable for weaving any conical or cylindrical containers and has relatively high universality.
