The utility model discloses a sample plate piece cart, which relates to the technical field of carts, and comprises a frame, a support assembly and a roller assembly, the support assembly comprises a plurality of first support rods, a plurality of second support rods and two adjusting rods arranged on the frame at intervals along the length direction of the frame, the number of the first support rods is more than one, and the number of the second support rods is more than one. The number of the first supporting rods is equal to that of the second supporting rods, the first supporting rods are arranged on one adjusting rod at intervals in the height direction of the frame, and the second supporting rods are arranged on the other adjusting rod at intervals in the height direction of the frame. The first supporting rod and the second supporting rod located at the same height are used for supporting the two ends of the sample plate piece correspondingly. The roller assembly is arranged at the bottom of the frame. By arranging the first supporting rods and the second supporting rods which are arranged in the vertical direction, the sample plate pieces can be stacked in a layered mode, contact between the sample plate pieces is eliminated, and therefore the situation that the sample plate pieces deform due to gravity extrusion is eliminated.

The utility model provides a kind of drainage device of pool body, including pool body, the basin of being set on the pool body, the water outlet of being opened on the basin, further include the drainage connector for being used to supply the water in basin to discharge outward, which is set on the lower end of the basin, the drainage hose for guiding when drainage connector drains, which is set on the lower end of the drainage connector, the control member for being used to rise or drop on pool body when being driven by external force, which is liftable and set on the pool body at the side of basin, the connecting wear ring for being used to supply drainage hose to pass through, which is set on the control member, the inverted U-shaped part of drainage hose, which passes through connecting wear ring, is formed for storing water in basin when being higher than liquid level in basin, and after being lower than liquid level in basin, make water in basin discharge outward.

This utility model relates to a forming machine for producing woks. It features a main frame with a mold rotatably connected to its center. A swing frame is rotatably connected to the main frame, and a cylinder is mounted on the top of the swing frame. The piston rod of the cylinder is connected to a connector, and a spinning roller is rotatably connected to the connector. A mounting frame is connected to the front of the connector, and a liquid storage box is connected to the front of the mounting frame. A removable cover is provided on the top of the liquid storage box, and an oil supply pipe is connected to the bottom of the liquid storage box. One end of the oil supply pipe is connected to a nozzle, and the other end of the oil supply pipe passes through the liquid storage box and is equipped with an oil pump. A collection component for collecting liquid is provided in the center of the main frame. The advantage is that when the spinning roller and the rotating steel plate are pressed together, the oil pump synchronously drives the nozzle to spray atomized lubricating liquid onto the interface between the spinning roller and the steel plate, forming a continuous oil film between the friction pairs. This achieves liquid isolation at the friction interface, thereby completely eliminating direct metal-to-metal contact between the roller and the steel plate, achieving bidirectional protection.

The utility model discloses an automatic mechanical transmission and a vehicle. A bearing seat is arranged in a clutch shell; a shaft penetrates through the clutch shell and the bearing seat; the bearing is assembled on a shaft in an interference manner; a bearing cover is arranged above the bearing, a through hole is formed in the bearing cover, and a shaft penetrates through the through hole of the bearing cover; the bearing cover is arranged below the bearing seat; the first shaft is sleeved with a sealing ring, and the sealing ring is assembled on the bearing cover in an interference mode. A tachometer wheel is arranged on the bearing seat and connected to a shaft in a rolling mode. The rotating speed sensor can be prevented from adsorbing scrap iron in oil, and therefore the problem that the rotating speed sensor fails due to the scrap iron is solved. The sealing ring can prevent oil from entering the clutch shell. And the tachometer wheel is fixed at one end of a shaft in the clutch shell, so that the tachometer wheel is prevented from being in contact with oil. The rotating speed sensor is not in direct contact with the oil liquid, so that the influence of scrap iron in the oil liquid on signals is eliminated.

A swash plate compressor has a boss (178, 179) on an inner face (175, 176) of a bridge (174) of its piston (170) that contacts only an outer face (163, 164) of a swash plate (160) between edges (166, 167) to eliminate wear at the edges and thereby increase the life of the compressor.
