Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings and embodiments:

[0019] Such as figure 1 , figure 2 As shown, the present invention is composed of a cam handle 1, a cylindrical pin 2, a split pin 3, an upper washer 4, a tie rod 5, a rubber sleeve 6, a lower washer 7, a first nut 8, a cam 9 and a second nut 10, wherein the tie rod 5 It is a linear round rod structure, and threads are machined on the circumferential surface of the lower end of the tie rod 5. The threaded section at the lower end of the tie rod 5 is fitted with a first nut 8 and a second nut 10 through threaded fit, and the first nut 8 is located at the second Above the nut 10, the two are close together. An upper gasket 4, a rubber sleeve 6 and a lower gasket 7 are also sleeved on the pull rod 5. The upper gasket 4 is located above the rubber sleeve 6, and the bottom surface of the upper gasket 4 is in contact with the top surface of the rubber sleeve 6. The rubbe...

Abstract

The invention discloses an engine airtight detection rapid plugging head, comprising a cam handle, a cam, a pull rod, an upper gasket, a rubber sleeve, a lower gasket and a nut; wherein the pull rod is sheathed with the upper gasket and the rubber sleeve, the upper gasket is arranged above the rubber sleeve, the bottom of the rubber sleeve is adhered with the lower gasket, the lower gasket is limited by the nut sheathed on the pull rod; the cam is arranged above the upper gasket, the cam is arranged at the bottom of the cam handle, and the cam is hinged with the upper end of the pull rod. The invention can effectively reduce mounting time of plugging head, plugging efficiency is improved, the semidiameter of the cam handle rotating downward is small, the plugging head can be used in narrow space, and the plugging head has the characteristics of simple structure, easy and rapid operation and wide application range.

Description

Technical field [0001] The invention belongs to the technical field of engine air tightness detection, and specifically relates to a quick plugging head for engine air tightness detection. Background technique [0002] When the engine is being tested for airtightness, the round hole on the engine needs to be blocked with a plugging head. At present, the commonly used engine air-tight detection plugging heads such as image 3 As shown, it consists of a rotating handle 11, a pull rod 5, an upper washer 4 and a rubber sleeve 6. The rubber sleeve 6, an upper washer 4 and a rotating handle 11 are sequentially sleeved on the pull rod 5 from bottom to top. The rubber sleeve 6 has a certain taper. The outer circle of the lower end of the rubber sleeve 6 is smaller than the outer circle of the upper end. The bottom end of the rubber sleeve 6 is limited by a step at the bottom of the pull rod 5, and the rotating handle 11 is threadedly engaged with the pull rod 5. The above structure uses ...
