Meanwhile, the phenomenon that signals are weak when small food passes through the detector is avoided.

This application discloses a cable laying assembly that enables lifting and lowering control of the roller mechanism, thereby allowing for unilateral lifting and lowering operations and rotational support on one side of the cable reel. Furthermore, by employing four cable laying assemblies, the entire cable reel can be lifted, lowered, and rotated simultaneously. Moreover, because this embodiment utilizes a component-based collaborative working logic, a single integrated cable reel laying device is no longer required, greatly facilitating transportation. Additionally, by lifting the cable reel from the ground, reliance on cranes is eliminated, making it better suited for laying cables in complex terrain and space-constrained areas.

The utility model belongs to foot switch technical field especially is a kind of lifting drive device of foot switch, including bottom plate, the cavity groove of bottom plate is equipped with foot control module, foot control module includes the limiting frame of embedding in cavity groove, the telescopic plate of adaptation on limiting frame. The utility model is installed foot control module, lifting drive module on bottom plate, two slidable round poles are provided on lifting drive module, travel sensor is installed between the mounting plate of wedge block one side and vertical board, when footboard drives telescopic plate to move down, the roller of its one side can be contacted with corresponding wedge block respectively, drive corresponding round pole to retract, then trigger corresponding travel sensor, control lifting device to lift, reach the purpose of controlling lifting device lifting by one footboard, solve the device of present stage and need two footboard control device to lift, then make the problem of cumbersome operation, error-prone.

The application has the advantages of simple structure, improved walking stability and reduced maintenance cost in the later period. The application has the advantages of simple structure, easy operation and reduced maintenance cost in the later period.

The hidden fan lamp comprises a circular-truncated-cone-shaped fan base, a fan motor and fan blades are fixed to the top face of the circular-truncated-cone-shaped fan base, and a center light source plate and a circular lampshade are fixed to the bottom face of the circular-truncated-cone-shaped fan base. An annular lifting air guide table, a mounting seat, a control motor, a transmission screw rod and a sliding block body are further arranged; a horn-shaped protruding cylinder is integrally formed on the inner wall of the annular lifting air guide table, and a lifting receding groove hole is formed in the side wall of the horn-shaped protruding cylinder. An annular air outlet is formed between the edge of the circular-truncated-cone-shaped fan base and the inner wall of the horn-shaped protruding cylinder. The mounting seat is fixed on the annular lifting air guide table, and the sliding block body is fixed on the circular-truncated-cone-shaped fan seat and is in threaded connection with the transmission lead screw. The fan is reasonable in structural arrangement, the motor, the transmission lead screw and the sliding block body are controlled to be matched, the circular-truncated-cone-shaped fan base ascends and descends in the horn-shaped protruding cylinder, the size of an air outlet is adjusted, the overall appearance attractiveness can be improved, and the air blowing requirements of different air volumes are met.

The utility model provides a telescopic moving structure for a goods shelf, and relates to the technical field of goods shelves. The telescopic moving structure for the goods shelf is installed on a goods shelf bottom support in pairs and comprises a connecting rod, a plurality of driving assemblies and a plurality of moving assemblies. The moving assembly is installed on the connecting rod, and the driving assembly is hinged between the connecting rod and a bottom support of the goods shelf and used for driving the connecting rod and the moving assembly to ascend and descend so that the goods shelf can move rapidly. The telescopic moving structure for the goods shelf is simple in structure and convenient to operate, lifting control of the trundles is achieved through linkage matching of the telescopic assemblies, the connecting rods and the moving assemblies, the goods shelf can be stably supported in use, and the trundles can be rapidly dropped to move and flexibly switched between the positioning state and the moving state when the goods shelf needs to move.
