This utility model relates to the field of production line material stacking technology and discloses a production line material stacking positioning card. The upper end of the base is fixedly installed with a surrounding plate. The two sides of the surrounding plate are symmetrically provided with storage slots. The bottom of the two storage slots is fixedly installed with two connecting seats. The upper end of the two connecting seats is provided with a groove. By setting a lifting mechanism composed of a bidirectional adjusting screw, a movable block and a diamond-shaped folding plate, when the handle is turned to drive the bidirectional adjusting screw to rotate, the reverse threads at both ends drive the movable block to move towards or away from each other, causing the folding plate to rotate around the shaft as the fulcrum. The horizontal displacement of the movable block is efficiently converted into the vertical lifting of the connecting seat, realizing precise adjustment of the lower pressure plate height. Because of the action inside the storage slot, the folding plate can be completely stored in the storage slot when folding, greatly reducing the axial space occupation in the non-working state and solving the installation and operation limitations in a space-constrained environment.

The utility model relates to a gravity blanket which comprises a blanket body, the blanket body is formed by weaving thick threads, the thick threads comprise a flexible net-shaped body, the flexible net-shaped body extends in the axial direction of the thick threads, and ventilation net holes are formed in the flexible net-shaped body. Due to the fact that the thick lines are heavy, additional weighting materials do not need to be adopted, the problem of uneven pressure is avoided, the outer surfaces of the thick lines are the flexible net-shaped bodies, the gravity blanket has the advantage of being soft and good in air permeability, and the problems that an existing gravity blanket is poor in air permeability, uneven in pressure and difficult to bend are solved.

The utility model relates to the field of coffee beverage making appliances, and discloses a coffee powder pressing device with a balancing constant force structure, which comprises a main body, a first knob is fixedly connected to the top end of the main body, the first knob is connected with a moving plate through an extrusion assembly, and a rotating plate is fixedly connected to the bottom end of the moving plate. An inner gear ring is fixedly connected to the inner wall of the main body, a first gear is connected to the inner side of the inner gear ring in a meshed mode, the outer wall of the first gear is rotationally connected to the inner wall of the main body, and the first gear is connected with a rotating plate through a transmission assembly. According to the coffee machine, coffee powder in the powder bowl is compacted by pressing the moving plate and the rotating plate downwards, compared with manual powder pressing, the mode can avoid uneven pressure caused by human factors, it is guaranteed that the powder pressing force is the same every time, the consistency and stability of coffee extraction can be improved, the device further has the powder distribution function, and therefore the coffee machine is convenient to use. And additional powder distribution tools are reduced, and the application range of the device is widened.

The utility model discloses a rewinding machine relates to the field of steel wire net processing, include: raw material frame and rewinding frame, the raw material frame top swing is provided with raw material roll, the raw material roll is used for winding the uncompacted steel wire net, the rewinding frame top swing is installed with rewinding roll, the rewinding roll is used for winding steel wire net, the rewinding roll one side is provided with the recess, the recess is used for fixing steel wire net, this kind of rewinding machine, through setting up bilateral symmetry's auxiliary shaft compaction mechanism, realized the dynamic pressurization of steel wire roll layer by layer, the inside symmetrical arrangement of movable frame no.

The invention discloses a cable connector and a wiring method, and the cable connector comprises a main body housing which is provided with a main wire hole and a plurality of secondary wire holes surrounding the main wire hole, and a communication cavity is formed in the main body housing; the conduction sheet is fixed on the bottom wall of the cavity; the pressing ring is arranged in the cavity and is connected with the linkage part extending to the outside; the locking screw sleeve is rotatably arranged at one end of the main body shell in a sleeving manner and is provided with a thread part, a connecting part connected with the linkage part and an extending hole; and the locking sleeve is arranged in the locking screw sleeve, and the outer wall of the locking sleeve and the inner wall of the extending hole are provided with inclined plane structures which are matched with each other. When the locking screw sleeve is rotated, the linkage part drives the pressing ring to move downwards to press the secondary cable core, and the inclined surface structure enables the locking sleeve to radially contract to tightly hold the main cable, so that mechanical locking of the main cable and electrical connection of a plurality of secondary cables are synchronously completed through single operation, the wiring efficiency is improved, and the connection consistency is ensured.
