The utility model discloses a one-barrel half multi-pipe composite chimney, which belongs to the technical field of industrial chimneys, and comprises a lower outer barrel, a plurality of lower inner barrels are fixedly connected in the lower outer barrel through a support, a hole sealing platform is fixedly mounted at the top of the lower outer barrel, an upper single barrel is mounted at the top of the hole sealing platform, and a plurality of lower inner barrels are fixedly mounted at the bottom of the upper single barrel. A smoke exhaust hole is formed in the position, corresponding to the lower inner cylinder, of the hole sealing platform, the lower opening position of the smoke exhaust hole is flexibly connected with the top end of the lower inner cylinder through an expansion joint, an inner cylinder pulley is installed on the periphery of the lower inner cylinder, and the periphery of the inner cylinder pulley is movably connected with the inner side wall of the lower outer cylinder. A plurality of inner cylinders can be arranged in the lower outer cylinder and matched with the upper single cylinder to guarantee the smoke exhaust height, so that the anti-corrosion area is reduced, the structure of the upper single cylinder is reduced, the overall structure consumption and the manufacturing cost are greatly reduced, and resources and the investment cost of a user are saved.

The utility model discloses a rotary foot massage device and an automobile seat with the same, which comprises a base, massage parts are rotatably mounted on the upper sides of the left end and the right end of the base, massage bumps are arranged at the top ends of the massage parts, and the massage bumps are arranged to deviate towards one side relative to the rotating center line of the massage parts; a driving mechanism is arranged on the base and used for driving the massage component to rotate in the horizontal plane where the foot bottom is located. The foot massager has the advantages that the massage component is rotatably mounted on the base, the massage component can horizontally rotate in the horizontal plane where the foot sole is located, the massage bumps on the massage component can comprehensively stimulate acupuncture points of the foot sole in a targeted mode, the massage effect is improved, and meanwhile the massage effect is improved. In addition, the massage device is light and thin in overall structure and does not occupy extra space in the automobile.

The vehicle-mounted foot bottom massager comprises a foot supporting base body, the foot supporting base body is provided with a left foot sole supporting area and a right foot sole supporting area which are distributed left and right, and massage assemblies are rotationally installed in the left foot sole supporting area and the right foot sole supporting area respectively; the massage assembly comprises a rotating shaft, a support extending outwards in the radial direction of the rotating shaft and a roller rotationally installed at the far end of the support, and massage protrusions are distributed on the surface of the roller. A driving mechanism used for driving the rotating shaft to rotate is arranged in the foot supporting base body, and the driving mechanism drives the rotating shaft to rotate and can drive the rollers to intermittently move upwards in a protruding mode in the corresponding sole supporting areas in a rotating mode. The massage roller has the advantages that when the driving mechanism drives the rotating shaft to rotate, the roller can protrude upwards intermittently in a rotating mode, the massage protrusions on the surface of the roller can effectively stimulate acupuncture points on the foot bottom, the tension feeling of foot muscles is relieved, and the massage roller has the advantage of being good in massage effect.

This utility model provides a zero-point exchange device for a four-axis machine tool, including a four-axis machine tool and a loading machine. The four-axis machine tool and the loading machine are signal-connected. The loading machine is horizontally positioned and fixed to the front of the four-axis machine tool. The loading machine has a frame that can be fixed to the ground. Two horizontally sliding moving components are mounted on the frame. Each moving component has a tray that can slide back and forth. A rotatable zero-point exchange platform is mounted on the tray. The four-axis machine tool has a processing table that can dock with the tray. The processing table has a rotating mechanism that docks with and drives the zero-point exchange platform. The loading machine is designed with two moving components, each equipped with a tray and a zero-point exchange platform. By alternating the use of the two trays, a mode of simultaneous processing and loading can be achieved, significantly reducing machine tool downtime, improving production efficiency, and reducing the labor intensity of operators.
