In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 to 6, the electric field structure 100 of the present invention includes a plurality of first electrode plates 1 arranged at intervals, a connecting screw rod 2 for connecting the first electrode plates 1, a plurality of second electrode plates 3 arranged alternately with the first electrode plates 1, spacers 4 arranged at two sides of the second electrode plates 3 for fixing the second electrode plates 3, and fixing structures 5 arranged at two ends of the connecting screw rod 2.

The second electrode plate 3 is provided with a through hole 31 for the connection screw rod 2 to pass through.
The first electrode plate 1 is provided with a through hole 11 for the connecting screw rod 2 to pass through. The size of the through hole 31 is larger than that of the through hole 11, and the through hole 31 coincides with the axis of the through hole 11. The first electrode plate 1 is provided with at least two first protrusions 12 and at least one second protrusion 13 which protrude outwards along the axial direction of the connecting screw rod 2.
The through hole 11 includes a main hole 111, and a relief portion 112 extending outward from an edge of the main hole 111.
The connecting screw rod 2 comprises a rod-shaped main body part 21, at least one group of clamping components 22 arranged on the main body part 21 and used for clamping the first electrode plate 1, and screws 23 arranged at two ends of the main body part 21 and used for fixing the main body part 21.
The body portion 21 is circular in cross section. The main body 21 is hollow, and has internal threads at both ends thereof for fixing to the screws 23.
The retaining assembly 22 includes at least three sets of fixing members 221 extending axially along the body portion 21.
The fixing member 221 includes a first fixing member 222 and a second fixing member 223 which are arranged at intervals, the first fixing member 222 and the second fixing member 223 are arranged at intervals, and the first electrode plate 1 is clamped between the first fixing member 222 and the second fixing member 223. The thickness of the first electrode plate 1 is equal to the distance between the first fixing member 222 and the second fixing member 223, so that the first electrode plate 1 is just clamped between the first fixing member 222 and the second fixing member 223, and the axial shake is reduced.
The distance between any two adjacent sets of fixing pieces 221 is equal to ensure that the first electrode plates 1 are arranged at equal intervals.
The connecting screw rod 2 has a first state in which the retaining assembly 22 is accommodated in the positioning portion 112, and a second state in which the first electrode plate 1 is retained in the first fixing member 222 and the second fixing member 223 after rotating relative to the first state. When the connecting screw rod 2 is in the second state, the fixing part 221 defines the position of the first electrode plate 1, and prevents the first electrode plate 1 from moving relative to the connecting screw rod 2 along the axial direction of the connecting screw rod 2.

When the connecting screw rod 2 is installed, the fixing member 221 passes through the yielding portion 112 and then rotates, when passing through the first protrusion 12, the connecting screw rod 2 displaces a certain distance in the extending direction of the first protrusion 12 to yield, when passing through the second protrusion 13, the connecting screw rod 2 displaces a certain distance in the extending direction of the second protrusion 13 to retain the first fixing member 222 between the two first protrusions 12, and at this time, the connecting screw rod 2 cannot easily rotate in the forward direction and the reverse direction to be in a retaining shape.
The fixing structure 5 is provided with a limiting part clamped with the connecting screw rod, and the limiting part is clamped with the connecting screw rod 2 after the connecting screw rod rotates in place, so that the connecting screw rod 2 can be prevented from reversely rotating. The screw 23 passes through the fastening structure 5 to fasten the connecting screw 2 to the fastening structure 5.
The number of the fixing members 221 is at least two, and at least two fixing members 221 are arranged in a circumferential array with the axis of the main body 21 as an axis.
The first fixing member 222 and the second fixing member 223 protrude radially outward from ends facing away from each other toward ends adjacent to each other. In this embodiment, the first fixing member 222 and the second fixing member 223 are formed by punching from the main body 21. The production method of the connecting screw rod 2 comprises the following steps: the first fixing member 222 and the second fixing member 223 are punched on a steel plate, and then the steel plate is rolled into a tube shape.
The electric field structure 100 and the connecting screw rod 2 of the invention can fix a plurality of first electrode plates 1 by arranging the clamping component 22, and the equidistant installation can be realized more easily; the internal threads are arranged at the two ends of the main body part 21, so that the connecting screw rod 2 is convenient to fixedly install. The electric field structure 100 and the connecting screw rod 2 are simple in structure, convenient to install and low in cost.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
