As shown in Figure 1, a kind of diaphragm, including supporting element 2 and rubber bound edge 1, the supporting element 2 are nylon supporting element,
Rubber bound edge 1 forms dismountable clamping structure, is plugged with copper insert inside supporting element 2 in being wrapped in 2 top of supporting element.
Supporting element 2 as shown in Figure 3, the supporting element 2 include integrally formed spherical clamping portion and guide post 23, the card
Socket part includes the first clamping portion 22 and the second clamping portion 21 set gradually from top to bottom, and first clamping portion 22 is disk
Shape, top surface are integrally arched upward upwards, form arch portion, i.e. 22 top surface of the first clamping portion is spherical surface, and second clamping portion 21 is
Disc, and the diameter of the first clamping portion 22 is less than the diameter of the second clamping portion 21, the first clamping portion 22 and the second clamping portion 21
Between formed annular groove 24, pass through the structure and rubber bound edge 1 of the first clamping portion 22, the second clamping portion 21 and annular groove 24
Realize clamping.In addition, it is broken in order to prevent, edge between guide post 23 and the second clamping portion 21 since the length of guide post 23 is longer
Circumferentially it is evenly arranged with several reinforcing ribs 27.
The shaft core position of the guide post 23 of the supporting element 2 offers cylindrical cavity, and guide post, top are run through in cylindrical cavity bottom end
It extends at annular groove 24.The cylindrical cavity includes the installation cavity 26 being connected and deformable cavity 25, the diameter of installation cavity 26
Greater than the diameter of deformable cavity 25, i.e., ring-shaped platform is formed between installation cavity 26 and deformable cavity 25, copper insert grafting enters the installation
In chamber 26, top leans with ring-shaped platform, and bottom end and the bottom surface of installation cavity 26 are flush, so that copper insert be made to cannot be introduced into
In deformable cavity 25.
Rubber bound edge 1 as shown in Figure 4, including integrally formed ring edge 11, arch upward portion 12 and annular bound edge portion 13,
The first type chamber 14 identical with the first clamping portion 22,21 shape of the second clamping portion, second type chamber 15 are formed in rubber bound edge 1, the
It is connected between one type chamber 14, second type chamber 15 by adapter cavity 16, the diameter of adapter cavity 16 is less than the first type chamber 14, second type chamber
15 diameter, 22 grafting of the first clamping portion enter in second type chamber 15, and 22 grafting of the second clamping portion enters in the first type chamber 15, to make
Supporting element 2 is not easy to deviate from out of rubber bound edge.
