[0021] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, an assembly structure of an industrial control membrane material includes a rubber frame 1, in which a receiving groove 11 is provided; a diaphragm 2 is provided in the receiving groove, and a positioning structure is provided on at least one contact surface between the rubber frame and the diaphragm, including a dovetail groove 31 provided on the circumferential inner wall of the rubber frame, and a clamping head 32 provided on the circumferential outer wall of the diaphragm, with at least two clamping blocks 321, and the two clamping blocks are clamped and matched with the inner wall of the dovetail groove. The diaphragm is provided in the rubber frame and fixed by the positioning structure. It should be noted that the positioning structure can be provided on both sides or only once. The positioning structure includes a clamping head and a dovetail groove. The clamping head is inserted into the hand to achieve positioning and clamping with the inner wall of the dovetail groove through the two clamping blocks, which reduces the occurrence of abnormalities, is more efficient, and improves the quality of the product.

[0022] In this embodiment, as shown in the figure, a deformation groove 322 is also included, and the deformation groove is arranged between the two blocks. When the block is inserted, the outer wall will be stressed, and the deformation groove provides space for the block to deform inwards, which is convenient for loading. After loading, the block will return to its initial state due to its own deformation and match the inner wall of the dovetail groove.

[0023] In this embodiment, as shown in the figure, the deformation groove is arranged between the two clamping blocks, which is more conducive to the deformation of the two clamping blocks.

[0024] In this embodiment, as shown in the figure, at least two positioning structures are provided between the right inner wall of the plastic frame and the right outer wall of the diaphragm. The two positioning structures are arranged opposite to each other up and down.

[0025] In this embodiment, as shown in the figure, the cross section of the deformation groove is rectangular.

[0026] In this embodiment, as shown in the figure, the left inner wall of the rubber frame is provided with a rectangular cross-section positioning groove 12, and the left outer wall of the membrane is provided with an insert 22 adapted to the positioning groove. The other side is a positioning groove and insert structure, which is more compact.
