The utility model discloses a kind of carbon fiber badminton racket production line opening die unit and final assembly equipment, opening die unit includes rack, fixed assembly and clamping assembly, the fixed assembly is connected with the rack, when the conveying unit of production line drives mold movement to opening die station, the fixed assembly is fixed to lower mold, the clamping assembly clamps upper mold and drives upper mold to move away from lower mold, the fixed assembly includes oppositely arranged top module, and the first electric cylinder of driving the top module, under the driving of the first electric cylinder, the top module abuts the slot between upper mold and lower mold, to fix lower mold. Through the synergistic mechanism of "lower mold structure limiting+upper mold vertical lifting", not only solve the lower mold without fixing, the mold misplacement problem caused by upper mold rotating opening, first fixed lower mold then separate upper mold Step operation, effectively avoid the risk of carbon fiber layer tearing caused by mold misplacement in traditional synchronous opening mold.

This utility model discloses an inspection fixture for identifying the position and orientation of mounting feet on a battery pack casing, comprising a main base plate and four bottom positioning components. The four bottom positioning components are located at the four corners of the upper surface of the main base plate, each including two first positioning plates, one second positioning plate, and one positioning latching block. The two first positioning plates are spaced parallel to each other along the length of the main base plate, and the second positioning plate is perpendicularly positioned inside the first positioning plate near the edge of the main base plate. The positioning latching block is installed in different positions within the bottom positioning components along different length directions. During inspection, the battery pack casing is placed flat on the main base plate, the second positioning plate latches onto the casing, and the first positioning plates and positioning latching blocks latch onto the mounting feet, enabling inspection of the X, Y, and Z axis directions and positions of the mounting feet. This utility model can replace manual measurement, simplify operation, improve inspection efficiency, avoid visual misjudgment, and thus prevent batches of defective products from flowing into the next process.

The utility model relates to a microalgae culture device for ecological restoration, which comprises a culture tank, an annular first cover plate mounted at the top of the culture tank through a flange, an annular second cover plate detachably mounted on the inner wall of the first cover plate, a third cover plate detachably mounted on the inner wall of the second cover plate, and a liquid distribution plate inserted into the upper part of the inner wall of the culture tank, a liquid inlet in the liquid distribution plate penetrates out of the side wall of the culture tank, a microalgae inlet located below the liquid distribution plate is formed in the side wall of the culture tank, a temperature equalizing cover is arranged on the inner wall of one side of the culture tank, a heating resistance wire is arranged in the temperature equalizing cover, air inlet pipes are arranged on the two sides of the top of the second cover plate in an up-down sealing and sliding mode, and the bottoms of the air inlet pipes are connected with aeration coil pipes; a lifting mechanism for driving the air inlet pipe to lift is arranged on the outer side of the culture tank, and illuminating lamps are vertically and hermetically arranged on two sides of the top of the third cover plate in a sliding manner. The illumination lamp and the aeration coil pipe are convenient to disassemble, assemble and clean, the height of the aeration pipe is adjustable, and the microalgae culture effect is good.

This utility model discloses a main support arm for a rotating rocking chair, including a base with a central column on the base and a drive mechanism for driving the central column to rotate on the base. The utility model provides a rubber limiting component on the inner wall of the upper end of the support cylinder. A mounting plate at the lower end of the central column is inserted into its mounting groove and fixed to the support plate. The drive mechanism is also fixed to the mounting plate. This ensures that the drive mechanism moves synchronously when the central column shakes, avoiding relative displacement and additional torsional and shear forces, effectively protecting the drive mechanism. Simultaneously, a detachable fixing ring assembly is provided at the upper end of the support cylinder to fix the rubber limiting component, and a lifting mechanism is provided at the lower end for easy replacement of the rubber limiting component.
