Embodiment
The medical brake system high-air-tightness Pneumatic actuator of holding one's breath shown in Fig. 1～3 includes base 1, and its unusual part is: be distributed with gas delivery passage 2 in the base 1 that the present invention adopted.Specifically, an end of this gas delivery passage 2 is provided with Anchor plate kit 3.For the ease of the gas conducting, on Anchor plate kit 3, be provided with vent 4 with gas delivery passage 2 conductings.Consider that the existence owing to tolerance in assembly process of each parts may influence whole tightness; Especially can influence the conducting place tightness of vent and gas delivery passage, the present invention is furnished with black box in the conducting punishment of vent and gas delivery passage.And, influencing the assembling effect in order when assembling, to prevent moving about of black box, base is provided with receiving groove, and the black box of order embeds in the receiving groove.For the ease of assembling, black box is a seal ring 7, and is promptly as shown in Figure 2.
Simultaneously, consider the installing and locating of Anchor plate kit 3, Anchor plate kit 3 belows link to each other with base 1 through fastener assembly.And, in order to play the better controlling effect, air film assembly 5 is installed on the Anchor plate kit 3, form gas receiving cavity 6 between the inwall of said air film assembly 5 and the Anchor plate kit 3.Moreover, in order to be connected, be provided with the linking assembly at the other end of gas delivery passage 2 with follow-up gas supply assembly.
With regard to the present invention's one preferred implementation; For air film assembly 5 is effectively located; And satisfy the tightness needs of gas receiving cavity 6, Anchor plate kit 3 peripheries that the present invention adopted are distributed with extension edge, and this extension edge contacts with air film assembly 5; Make extension edge be fastened on the outer edge of air film assembly 5, promptly as shown in Figure 2.
Further, in order to promote the firm degree and the movement travel of air film assembly 5, be distributed with fold breeze way 8 in the periphery of air film assembly 5.Thus, can help the free shrink and the expansion of gas receiving cavity 6.
Simultaneously, the linking assembly that the present invention adopts is a quick inserting joint 9, in quick inserting joint 9, is provided with gas channel.Like this, can cooperate existing breather line effectively to assemble.Moreover, consider integrally-built stability, fastener assembly is a tensioned screw 10.The outer edge of air film assembly 5 is fixed between Anchor plate kit 3 and the base 1, and Anchor plate kit 3 uses tensioned screw 10 tensions, and guarantees that tensioned screw 10 can not pass Anchor plate kit 3.Like this, when tensioned screw 10 locking, air film assembly 5 and seal ring 7 be by simultaneously compacted, promptly like Fig. 2, shown in 3.
In conjunction with actual use condition of the present invention, follow classical law, power=pressure * lifting surface area.Specifically, under the situation that air pressure limits,, increase active force through increasing active area.When quick inserting joint 9 was led to the gas of certain air pressure, gas arrived gas receiving cavity 6, and the intermediate portion of air film assembly 5 begins pressurized and rises.Afterwards, fold breeze way 8 prevents to occur in the intermediate portion uphill process of air film assembly 5 stretching.If after air film assembly 5 was stopped, the intermediate portion of air film assembly 5 just produced enough big power (power=pressure X lifting surface area), because this kind mechanism lifting surface area is bigger, the power of generation is also bigger.Afterwards, air film assembly 5 is given this propagation of pressure on the relevant brake assemblies that is attached thereto, the brake running of being correlated with.
Can find out through above-mentioned character express, behind employing the present invention, through the existence of gas receiving cavity, can adopt less gas to inject, can produce the needed power of brake running, satisfied brake is Safety performance timely and effectively.Simultaneously, simple structure of the present invention, cost of production is little, can apply on the corresponding with it medical braking device of holding one's breath.
