Sealing below with reference to Fig. 1 and Fig. 2 descriptions according to the ultrasonic inspection wheel 100 of the utility model first aspect embodiment
Component.
As shown in figure 1, according to the seal assembly of the ultrasonic inspection wheel 100 of the utility model first aspect embodiment, including
First seal assembly, the first seal assembly include the first fixing axle 11, the first axle seat apparatus 13 and the first mechanical press device 15.
Wherein, the first fixing axle 11 is the wheel shaft of ultrasonic inspection wheel 100.
Specifically, the first axle seat apparatus 13 is set in the first fixing axle 11, and the first axle seat apparatus 13 is relative to
One fixing axle 11 is rotatable, for example, the first axle seat apparatus 13 can rotate around the central axis of the first fixing axle 11.
First mechanical press device 15 is mechanical structure, and the first mechanical press device 15 is located at the first fixing axle 11 and first
Between axle seat apparatus 13, and the first mechanical press device 15 is configured to seal between the first axle seat apparatus 13 and the first fixing axle 11
Gap.Thus, when the wheel film 3 of ultrasonic inspection wheel 100 is arranged on the side of neighbouring first connecting seat 12 of the first fixing axle 11
When, specifically, 3 unilateral perforate of film is taken turns, the edge in the hole is tightly connected with the first axle seat apparatus 13, takes turns the sealing group of film 3 and first
Topping up chamber 31 is limited between part, because the gap between the first axle seat apparatus 13 and the first fixing axle 11 is sealed, so as to
The liquid being filled in topping up chamber 31 will not leak.
Thereby it is ensured that the sealing effectiveness of topping up chamber 31, and compared with traditional magnetic seal component, cost is low, releases
International limitation technically.
According to the seal assembly of ultrasonic inspection wheel 100 of the present utility model, by setting the first mechanical press device 15, when
When seal assembly is used cooperatively with wheel film 3, good sealing effect, and reduce the cost of seal assembly.
According to some embodiments of the utility model, the first connecting seat 12 is fixed with the first fixing axle 11 (for example, as schemed
Shown in 1, the first connecting seat 12 is fixed on the end of the first fixing axle 11, but not limited to this), now the first connecting seat 12 relative to
First fixing axle 11 is fixed.Formed with the first mounting groove in first axle seat apparatus 13, the first connecting seat 12 is adjacent to the
One mounting groove is set.Wherein, the first mounting groove can be by a side surface of neighbouring first connecting seat 12 of the first axle seat apparatus 13
Inwardly concave to be formed, i.e. the side of the first connecting seat of direction 12 of the first mounting groove is opened wide, to simplify the first axle seat apparatus 13
Processing technology, reduce processing cost.
First mechanical press device 15 is only against between the inwall of the first mounting groove and the first connecting seat 12.As shown in figure 1,
" inwall of the first mounting groove " can be the inner surface relative with the first connecting seat 12 of the first mounting groove (for example, such as institute in Fig. 1
The left surface shown).It is connected thus, it is possible to which the internal face of the first mechanical press device 15 and the first mounting groove and first is effectively ensured
The corresponding surface of seat 12 is close and fully contacts, so as to which the liquid in topping up chamber 31 will not be fixed by the first mounting groove and first
Gap outflow between axle 21.Preferably, the bottom wall and side wall of the first mechanical press device 15 and the first mounting groove only support, with
It is further ensured that sealing effectiveness.
According to some specific embodiments of the present utility model, as shown in figure 1, the first mechanical press device 15 is included along first
The first revolving part 151 and the first fixation pressure part 152 that the axial direction of fixing axle is set gradually, the first revolving part 151 are fixed on
In one mounting groove, now the first revolving part 151 is fixed, i.e. the first revolving part 151 relative to the first axle seat apparatus 13
Can be with the synchronous rotary of the first axle seat apparatus 13.For example, the first revolving part 151 can be interference fitted in the first mounting groove, the
One revolving part 151 preferably contacts with the inwall and side wall of the first mounting groove, to be further ensured that sealing effectiveness.
