The invention discloses an electrical conduction structure and an on-machine measuring device including it, which belongs to the technical field of mechanical processing. Through the corresponding setting of the first body and the second body, the corresponding setting of slots and spring grooves on the two bodies is used. , combined with the combination of two electrical conduction components, spring sheets, guide grooves and other structures, it can effectively realize the closeness and corresponding matching of the two bodies and the reliable packaging of the electrical conduction components on the first body when the electrical conduction structure is not working . The electrical conduction structure of the present invention has a simple structure and is easy to set up, and can effectively realize the electrical conduction between related components, ensure the quality and reliability of the electrical conduction, and effectively ensure the effective operation of the electrical conduction components when they are not working. Protection, improve the service life of the electrical conduction structure, reduce the use cost of related components, and have good application prospects and promotion value.

The invention discloses a slide embedded kitchen ventilator which comprises a kitchen ventilator. The slide embedded kitchen ventilator is characterized in that the kitchen ventilator is embedded in an accommodating cavity, guide grooves are formed in the kitchen ventilator, guide blocks are arranged on a vertical wall, an inlet end is arranged at the end, which is close to users, of each guide groove, an outlet end is arranged at the end, which is far away from the users, of each guide groove, the inlet ends of the guide grooves are lower than the outlet ends of the guide grooves, a compression spring is arranged between the accommodating cavity and the back surface of the kitchen ventilator, a limiting check block is arranged on the accommodating cavity, the lower edge of the kitchen ventilator can be hooked by the limiting check block when the kitchen ventilator is in a working state, a return spring is arranged between the accommodating cavity and the limiting check block, and the extension direction of the return spring is consistent with the movement direction of the limiting check block. The slide embedded kitchen ventilator has the advantages that the limiting check block capable of moving back and forth relative to the accommodating cavity is arranged on a side of the accommodating cavity, is close to the users and is positioned below the kitchen ventilator in order to limit the kitchen ventilator, the return spring is arranged between the accommodating cavity and the limiting check block, and certain inward pull-back acting force can be provided by the aid of the return spring.

The invention relates to a rail wheel (1) having a wheel hub (3) that revolves on a fixed shaft (4), and an intermediate element (7) detachably connected to the wheel hub for rotation therewith, wherein a hollow shaft (12) is pressed onto the intermediate element for rotation therewith, and wherein the hollow shaft pressed onto the intermediate element forms an oil press fit with the intermediate element, wherein the hollow shaft is connected to a transmission element (13) for rotation therewith in order to transmit a torque to the wheel hub, and the hollow shaft is at least indirectly connected to at least one further component (17) for rotation therewith in order to transmit a torque to the wheel hub.
