This utility model relates to the technical field of biscuit processing equipment, specifically a hard-limit positioning pin mechanism. It includes a frame, a drive shaft located at the center of the top surface of the frame, a turntable mounted on the top of the drive shaft, and positioning components mounted on the outer circumference of the drive shaft. Multiple positioning seats are mounted on the top surface of the frame, circumferentially along the drive shaft. Rotation of the drive shaft causes the positioning components to engage with positioning seats at different positions. In this hard-limit positioning pin mechanism, the engagement of the positioning components and positioning seats forms a hard-limit structure. The arc-shaped design of the positioning head and positioning groove, combined with the preload of a spring, allows for precise engagement when the drive shaft drives the turntable to a preset position. This mechanism directly constrains the positional deviation of the turntable through mechanical hard limiting, effectively solving the problem of cumulative errors caused by speed fluctuations and component wear. It avoids misalignment between the forming cavity and the processing components, fundamentally eliminating uneven distribution of compressed biscuit raw materials and deformation of the shape.

This utility model discloses a finned structure for a marine heat exchanger, relating to the field of heat exchanger fin technology. It includes a heat exchanger body with finned bodies fixedly connected to its outer side. A protective plate is snapped onto one side of the heat exchanger body, and a first slot is formed on one side of the protective plate, extending into the interior of the heat exchanger body. Using this structure, the presence of the first locking block allows a second locking block to be inserted into a circular slot. By adjusting the second locking block to a non-corresponding angle with the second slot, the second locking block can be effectively engaged, preventing displacement of the protective plate and thus fixing its position. When the heat exchanger body needs to be disassembled later, the second locking block is first adjusted to a corresponding angle with the second slot, and then the first locking block can be directly pulled out, allowing the protective plate structure to be disassembled for convenient disassembly and assembly of the heat exchanger body.

This utility model belongs to the field of switch technology and discloses a dual-power transfer switch, including a housing, a micro switch, and a sliding cover. The housing has a handle operation hole, a sliding groove, and a first opening. The sliding groove has a first locking slot and a second locking slot at both ends. The micro switch is disposed inside the housing and opposite the first opening. The sliding cover is slidably mounted on the housing and has a first locking protrusion and a trigger portion passing through the first opening. The first locking protrusion is slidably connected to the sliding groove and can be locked into either the first or second locking slot. When the first locking protrusion is locked into the first locking slot, the sliding cover covers the handle operation hole, and the trigger portion triggers or moves away from the micro switch. When the first locking protrusion is locked into the second locking slot, the handle operation hole is exposed, and the trigger portion moves away from or triggers the micro switch. This dual-power transfer switch allows for switching between automatic and manual operation via the sliding cover, providing convenient operation. Furthermore, during automatic operation, the sliding cover can cover the handle operation hole.

The utility model relates to the technical field of roll core carriers, in particular to a roll core-shaped carrier based on roll cutting packaging, which comprises a tube body and a soft body layer, the tube body is a hollow round hard tube; a plurality of circles of soft body layers are arranged, and the soft body layers are wound on the outer surface of the pipe body; the pipe body is provided with a first notch; the soft body layer is provided with a second notch; the first notch and the second notch are both used for clamping the edge of the surface material so that the surface can be flush in the rolling, cutting and packaging process, and the rolling core indentation of the surface material can be improved. The utility model aims to provide the roll-core-shaped carrier based on roll-cut packaging by combining rigid support and flexible buffer, and the head end of the surface material is spliced with the gap of the roll-core-shaped carrier, so that the indentation is effectively improved.

The utility model discloses a reflection cover structure in the reflection cover field, which comprises a cover plate and a nixie tube, the side surface of the cover plate is provided with two fixing grooves, the two fixing grooves extend along the height direction of the cover plate, the two fixing grooves are symmetrically arranged, the bottom of the cover plate is provided with a support frame, the support frame is provided with a plurality of support plates, and the support plates are connected with the nixie tube.
