The utility model discloses a kind of carbon fiber tow wire guiding device, the utility model includes fixed frame, the fixed frame both ends are provided with guide roller, the guide roller of fixed frame same end is vertically parallel arrangement, the lateral wall of fixed frame both ends is vertically slidably connected with moving block, fixed frame lateral wall is provided with guide rod, guide rod outer wall is equipped with spring one located above moving block, fixed frame lateral wall is rotatably connected with threaded rod, threaded rod outer wall is threadedly cooperated with moving plate, moving plate one end and guide rod outer wall sliding fit, spring one both ends are connected with moving plate and moving block respectively;The utility model can change the extrusion force of spring one to moving block by adjusting the extrusion degree of moving plate to spring one by being provided with threaded rod, moving plate and guide rod, and further adjust the extrusion force of guide roller to tow, can make spring one compression after the extrusion force of guide roller to tow is reduced due to fatigue elastic force of spring one, ensure that the extrusion force of guide roller to tow is consistent.

The utility model discloses a kind of self-adapting elastic waist support mechanism and seat, including pedestal and waist support, elastic member is equipped between pedestal and waist support, elastic member can force waist support always have forward trend;Self-adapting guide structure is equipped between pedestal and waist support, self-adapting guide structure includes the sleeve portion set on one of pedestal and waist support, the sliding fit portion set on the other of pedestal and waist support, the inner hole of sleeve portion is the guide hole extending front and back;Sliding fit portion is inserted in guide hole and forms front and back sliding connection with sleeve portion;By leaving gap between sliding fit portion and sleeve portion, provide certain self-adapting adjustment space for sliding fit portion in guide hole, so that waist support can be deflected after being stressed, and smoothly slide back after deflection, avoid sliding fit portion to form larger extrusion force to guide hole inner wall, reduce the risk of jam when waist support slides, improve the use experience of seat.

This invention provides a joint module, a robotic arm, and a robot. In the joint module, an output shaft is rotatably disposed within a housing; a transmission shaft is rotatably disposed within the housing; a torque sensor is connected to both the output shaft and the transmission shaft, and is used to measure the output torque of the joint module; a flexible coupling is disposed between the torque sensor and the transmission shaft, connecting them and allowing for displacement between the torque sensor and the transmission shaft along the axial direction of the transmission shaft. Since the transmission shaft and the torque sensor do not contact each other, this avoids the pressure exerted by the transmission shaft on the torque sensor in the axial direction, further improving the accuracy of the torque sensor in measuring the actual output torque of the joint module.

This invention relates to the field of domain controllers, specifically to an airtightness detection device for a domain controller. The device includes a domain controller housing, with a first end cap and a second end cap respectively installed at both ends of the housing. A base plate is installed at the bottom of the housing. Two fixing holes are provided on each side of the housing along its width. A slide is provided on the underside of the base plate, and a base slidably connected to the slide is provided on the underside of the slide. Four positioning rods are evenly installed on the upper surface of the slide. A limiting ring is provided below the fixing holes. A driving component for moving the domain controller housing is installed on one edge of the upper surface of the base. A detection component for detecting the seal between the domain controller housing and the first and second end caps is installed on the side of the upper surface of the base away from the driving component. This invention has the following advantages: it avoids the second end cap being fully subjected to the extrusion force generated by the second cylinder, preventing the second end cap from being deformed and damaged by extrusion.
