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
The present invention relates to a kind of orifice sealing device that is used for the member inner chamber is carried out leak check.
Background technique
In the internal-combustion engine industry, usually to carry out leak check, will the joint mouth of pipe that certain pressure is arranged be sealed during inspection, adopt clip to add the sealing configuration of rubber parts usually the member inner chamber.It is long that this structure tightens up the time, and dismounting is trouble, and using effect is bad.
Summary of the invention
The object of the present invention is to provide a kind of loading and unloading easy, save time the orifice sealing device that using effect is good.
Technological scheme of the present invention is: orifice sealing device comprises rubber parts and hold-down mechanism, its improvements are that described rubber parts is the hollow rubber plug, described hold-down mechanism is made of screw rod and the pinch roller that has handle, one end of screw rod passes the rubber stopper endoporus and links to each other with nut, and the screw rod the other end becomes to be rotationally connected by straight pin with pinch roller.
Further scheme is: the two ends of described rubber stopper are provided with pad; Described pinch roller is a cam, and cam contacts with pad; Perhaps pinch roller is a disk, and the center and the disc centre of the straight pin of connecting screw rod and disk have eccentric distance e; Described disk has two, lays respectively at the screw rod both sides, is symmetrical arranged.
When the present invention uses, rubber stopper is in the raw put into the joint mouth of pipe, a hand is pinned rubber stopper another hand and is pulled handle, make pinch roller extruding pad, the rubber stopper axial shrinkage, radial dilatation, thereby with ferrule, unclamp hand and just can guarantee sealing state, only need oppositely pull handle during dismounting.It is easy, quick, laborsaving that the present invention loads and unloads, as long as select the rubber material of good springiness for use, and the size design of rubber stopper and pinch roller reasonable (knowledge is not difficult to accomplish routinely), just can guarantee sealing effect.Adopt above-mentioned further scheme, this device using effect is further improved.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1.
Embodiment
As figure, the endoporus that the threaded end of screw rod 2 passes rubber stopper 6 links to each other with lower levelling plate 7, nut 8, the screw rod the other end is rotationally connected for 3 one-tenth by straight pin 1 and disk, straight pin center and disc centre have throw of eccentric, handle 4 is arranged on the disk, Upper gasket 5 is arranged between disk and the rubber stopper, disk 3 has two, lay respectively at the both sides of screw rod 2, be symmetrical arranged.
