Abstract

The invention discloses an orifice sealing device, comprising a rubber part and a presser bar mechanism, wherein, the rubber part is a hollow rubber plug, the presser bar mechanism is composed of a screw stem and a pinch roller provided with a handle, one end of the screw stem penetrates through the inner hole of the rubber plug and then is connected with a nut, and the other end of the screw rod is rotationally connected with the pinch roller through a cylindrical pin. The pinch roller is a cam or a disc. The orifice sealing device is used for plugging a joint orifice when the tightness of the inner chamber of a member is tested in internal-combustion engine industry, has the advantages of simple, fast and laboring saving assembly and disassembly and good use effect, thereby deserving promotion and application.

Description

technical field [0001] The invention relates to a nozzle sealing device for checking the tightness of the internal cavity of a component. Background technique [0002] In the internal combustion engine industry, it is often necessary to check the tightness of the inner cavity of the component. During the inspection, the joint nozzle with a certain pressure must be sealed. Usually, the sealing structure of the clamp and the rubber part is adopted. The fastening time of this structure is long, the dismounting is cumbersome, and the use effect is not good. Contents of the invention [0003] The object of the present invention is to provide a nozzle sealing device which is easy to assemble and disassemble, saves time and has good use effect. [0004] The technical solution of the present invention is: the nozzle sealing device includes a rubber part and a pressing mechanism, the improvement is that the rubber part is a hollow rubber plug, and the pressing mechanism is compose...
