Meanwhile, since the power supply 1 is mounted on the upper cover 101 or the base 102 instead of the circuit board 103, the volume of the circuit board 103 is reduced, and the cost is further reduced; in addition, since the power fixing assembly 2 is located between the circuit board 103 and the upper cover 101 or the base 102, the length of the wire 11 between the power source 1 and the circuit board 103 can be properly shortened, and further the problem that the wire 11 is easy to jam the counting gear due to the siltation of the wire 11 is properly improved.

It should be noted that, the base 102 of the controller 100 is mounted on the base table of the metering device, the upper end 1021 is represented as one end of the controller 100 near the opening position of the air inlet and the air outlet of the base table, the lower end 1022 is represented as one end of the controller 100 near the mounting position of the metering module of the base table, and the upper end 1021 and the lower end 1022 are opposite ends on the controller 100; the upper end 1021 of the upper cover 101 and the upper end 1021 of the base 102 are both referred to as the same end of the controller 100, and the lower end 1022 of the upper cover 101 and the lower end 1022 of the base 102 are both referred to as the same end of the controller 100, and as shown in fig. 1, 2 and 3, the upper end 1021 is located above the lower end 1022 in the vertical direction.

Therefore, when the power supply 1 is installed in the power supply fixing assembly 2 and supplies power to the circuit board 103, the redundant wires 11 between the power supply 1 and the circuit board 103 can be wound up and then stored in the wire storage space 3, so that the situation that the wires 11 are blocked by the counter gear due to the fact that the lengths of the wires 11 are too long and are accumulated in the controller shell is further avoided.

In some embodiments of the present utility model, the first annular structure is a first closed annular structure, in other words, the adjacent collecting plates 22 are all connected, and the first closed annular structure and the bottom plate 21 form the wire receiving space 3, and since the first annular structure has no gap in the circumferential direction, the wire receiving space 3 has a better wire receiving effect.

Referring to fig. 4 and 6, in some embodiments of the present utility model, the first annular structure is a first open annular structure, in other words, the adjacent beam-receiving plates 22 are not all connected, and the first annular structure has a gap in its circumferential direction, compared with the first annular structure having no gap in its circumferential direction, in this embodiment, the cost of production can be reduced, but the receiving effect of the wire 11 is relatively reduced.

Obviously, in the present embodiment, since the wire pressing plate 23 is disposed on the beam-converging plate 22, the wire pressing plate 23 can limit the wires 11 located in the wire accommodating space 3, so that the wires 11 cannot escape from the wire accommodating space 3 and enter the controller 100, thereby avoiding interference to the rotation of the counting gear, and further solving the problem of preventing the counting gear from being easily blocked; meanwhile, due to the existence of the line pressing plate 23 and the limit effect on the wires 11, the height of the beam-converging plate 22 can be properly reduced, which is beneficial to reducing the production cost, and meanwhile, due to the reduction of the height of the beam-converging plate 22, the space occupied by the wire accommodating space 3 in the controller 100 is also reduced, so that the occupation of the power supply structure 10 in the internal space of the controller 100 is reduced, the production cost is further reduced, and the popularization and the economy of products are improved.

Further, the wire pressing plate 23 and the beam-receiving plate 22 can be welded, clamped or hinged, so long as the connection stability between the wire pressing plate 23 and the beam-receiving plate 22 is ensured, preferably, the wire pressing plate 23 and the beam-receiving plate 22 are hinged, the wire pressing plate 23 can also rotate along the hinged position, when a wire or a power supply needs to be replaced, as shown in fig. 4, the wire pressing plate 23 only needs to rotate upwards along the hinged position, so that the wire or the power supply can be detached, and the operation is convenient and labor-saving; and when the wire 11 needs to be limited through the wire pressing plate 23, as shown in fig. 4, only the wire pressing plate 23 is required to be rotated downwards along the hinge position until the wire pressing plate 23 moves to the limiting position, the limitation of the wire 11 can be realized, the wire 11 cannot escape from the wire accommodating space 3 and enter the controller 100, further, the interference to the rotation of the counting gear is avoided, and the problem of preventing the counting gear from being blocked easily is further solved.

Of course, when the wire pressing plate 23 moves to the limiting position, the wire pressing plate 23 is limited, so as to ensure the limiting effect of the wire pressing plate 23 on the wire 11, in other words, the position of the wire pressing plate 23 remains unchanged, in order to achieve the purpose of being limited when the wire pressing plate 23 moves to the limiting position, the wire pressing plate 23 can be fixedly connected with the bottom plate 21, the wire pressing plate 23 and the bottom plate 21 can be connected in a clamping or magnetic manner, and the like, so long as the connection stability of the wire pressing plate 23 and the bottom plate 21 is ensured, and the method is not limited herein.

Preferably, when designing the first buckle 5, the radius R 'of the arc-shaped surface 51 of the first buckle 5 is determined to be R' = (1.04-1.1) R according to the radius R of the power supply 1, so as to more conveniently clamp the power supply 1 into the power supply accommodating space 4; meanwhile, the magnitude of the fastening amount should be adjusted by combining the actual assembly condition and the assembly tightness, the larger the fastening amount is, the simpler the assembly is, but the assembly tightness is worse, the smaller the fastening amount is, the more complex the assembly is, but the assembly tightness is better, and it should be noted that, referring to fig. 5, the fastening amount is the distance between the nearest end of the first fastener 5 or the second fastener 6 near the power source 1 and the limiting plate 24 located at the same side.
