The invention discloses a modularized detection and control meter comprehensive practical training device. The device comprises a practical training operating platform and connecting wires, and is characterized by also comprising more than one practical training unit, wherein every practical training unit comprises a plurality of practical training elements; the practical training elements are arranged in iron boxes of a standard size so as to form independent modules; and the modules are arranged in corresponding installation frames on the panel of the practical training operating platform and are connected with one another by plugging wires and terminal strip wires. The modularized detection and control meter comprehensive practical training device can be freely combined, and can comprehensively and systematically perform the experiments of detection and control meters, the practical training and the skill training on students. By using the flexible combination and the variety of practical training contents, the creative thinking of the students is cultivated, conditions are created for strengthening the practical ability of the students, and the modularized detection and control meter comprehensive practical training device has high innovativeness and is used for novel automatic meter and control systems.

The invention discloses a jacquard shed fast adjustment device of a loaded griffe mechanism. The device includes: inner and outer griffe mechanisms symmetrically arranged near the inner and outer sides of a left and a right wallboard, alternate shed adjusting mechanisms, shed adjusting mechanisms, as well as large and small shed output shafts. The inner and outer griffe mechanisms respectively have paired griffe frame plates, hanger rod groups and griffe groups. Each end face and each end of the large and small shed output shafts are both equipped with radial strip teeth and positioning slots. The shed adjusting mechanisms and the alternate shed adjusting mechanisms both include positioning wedge blocks, shed adjusting tooth blocks, pin shafts and upper seats. The positioning slots are respectively provided with wedged positioning wedge blocks. The radial strip teeth are respectively engaged with the shed adjusting tooth blocks. Connecting rods are respectively hinged to the vicinity of each end of the paired griffe frame plates. The upper ends of the connecting rods are all fixed with the upper seats. The upper seats, the shed adjusting tooth blocks and the positioning wedge blocks are positioned through the pin shafts and are fixed. With no need for unloading, the device disclosed in the invention can realize fast shed adjustment, and has the advantages of high adjustment precision as well as large scope.
