And the gasket is arranged in the compression ring, and the closure plate is matched with the gasket, so that the sealing performance of the valve body is more reliable.

The utility model relates to the technical field of mechanical equipment, in particular to a plane boosting force hinge. The plane boosting force hinge comprises a plane outer hinge and a plane inner hinge; pin holes are formed in one end of the out-of-plane hinge and one end of the in-plane hinge, and hinge installation is achieved at the position where the pin holes are formed in one end of the out-of-plane hinge and the position where the pin holes are formed in one end of the in-plane hinge through the matching effect of pins and the boosting force bearing assembly. According to the plane boosting force hinge, a boosting force bearing assembly structure is additionally arranged on the basis of an original hinge structure, and an arranged boosting force bearing assembly comprises a bearing seat, a ball and a bearing cover; after the whole plane boosting force hinge is additionally provided with the totally-closed thrust bearing, the plane boosting force hinge is smoothly opened and closed in a high-bearing state, and the force is small; meanwhile, abrasion and friction sound do not occur after multiple heavy load tests, and the locking phenomenon does not occur after regular refueling.

The utility model discloses a steel structure civil air defense door which comprises a round door frame and a round door cover, a frame edge is arranged at the end, facing the round door cover, of the round door frame, an annular groove is formed in the inner side of the frame edge, a multi-leaf cam is rotationally connected to the end, facing the round door frame, of the round door cover, and locking assemblies are distributed on the periphery of the multi-leaf cam. The locking assembly comprises a guide sleeve extending in the radial direction of the round door cover, a guide column is slidably connected into the guide sleeve, one end of the guide column can be inserted into the annular groove, the other end of the guide column is rotationally connected with a guide wheel with the wheel face tightly attached to the multi-blade cam, and a limiting hole extending in the length direction of the guide sleeve is formed in the guide sleeve. A movable spring pin arranged on the guide column is connected into the limiting hole in a sliding mode, a fixed spring pin arranged on the guide sleeve is arranged at the end, facing the multi-blade cam, of the movable spring pin, and an extension spring is connected between the fixed spring pin and the movable spring pin. A driving assembly is further included. The civil air defense door has the advantages of being labor-saving in opening and closing and convenient to lock, and is complete in overall function and high in practicability.

The utility model is applicable to the technical field of feed processing, and provides an anti-blocking blanking device for processing and producing animal feed additives, which comprises a bottom plate, a box body is installed at the upper end of the bottom plate, and a discharging notch is formed in the position, corresponding to the surface of the bottom plate, of the lower portion of the box body. According to the anti-blocking discharging device for processing and producing the animal feed additive, the rotating shaft is arranged to be matched with the partition plate, so that materials can be pushed to be discharged, blockage caused by material accumulation is avoided, meanwhile, the discharging speed of the materials can be controlled, the subsequent processing effect of feed is improved, and the production efficiency is improved. The connecting shaft and the rotating shaft are in sliding insertion connection, the connecting mode is simple and convenient, overall disassembly and assembly of the rotating shaft and the partition plate are facilitated, the sliding plate and the connecting frame are arranged, the connecting frame can be pulled outwards to enable the sliding plate to slide out of a sliding groove in the top of the box body, and the sliding plate and the connecting frame are matched to achieve opening and closing of a box door on the right side of the box body. And the opening and the closing are quicker and more labor-saving.
