Description

The airtight detection quick blocking of engine head
Technical field
The invention belongs to the airtight detection technique of engine field, specifically, the particularly quick blocking head of the airtight detection of engine.
Background technology
Engine need block the circular hole on the engine with block head when carrying out airtight detection.At present, the airtight detection block head of engine commonly used as shown in Figure 3, constitute by rotary handle 11, pull bar 5, upper gasket 4 and rubber sleeve 6, suit rubber sleeve 6, upper gasket 4 and rotary handle 11 successively from the bottom up on pull bar 5, wherein rubber sleeve 6 has certain tapering, the cylindrical of these rubber sleeve 6 lower ends is less than the cylindrical of upper end, and the bottom of rubber sleeve 6 is spacing by the step of pull bar 5 bottoms, described rotary handle 11 and pull bar 5 threaded engagement.Above structure is utilized spiral principle, and when the shutoff before carrying out the airtight detection of engine was worked, the rubber sleeve with block head partly stretched in the circular hole that needs shutoff earlier, rotate rotary handle again, exert pressure to the rubber sleeve that stretches in the circular hole, make rubber be subjected to compression swelling, to reach the shutoff purpose.Because the rotation time of rotary handle compressing rubber cover is longer, can increase the set-up time of block head, thereby influence the efficient of shutoff; Simultaneously, the radius of gyration of rotary handle is bigger, is not suitable for the local use of space-constrained.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of airtight detection block head of engine that can effectively improve shutoff efficient.
Technical scheme of the present invention is as follows: the airtight detection quick blocking of a kind of engine head, comprise cam handle, cam, pull bar, upper gasket, rubber sleeve, lower gasket and nut, on pull bar, be set with upper gasket and rubber sleeve, wherein upper gasket is positioned at the top of rubber sleeve, its key is: the bottom surface of described rubber sleeve and lower gasket are fitted, and this lower gasket is spacing by the nut of suit on the pull bar; Be provided with cam above described upper gasket, this cam is arranged at the bottom of cam handle, and the upper end of cam and pull bar is hinged.
The present invention utilizes the principle of cam mechanism, when the shutoff before carrying out the airtight detection of engine is worked, rubber sleeve with block head partly stretches in the circular hole that needs shutoff earlier, the upper end that grasps cam handle then is toward pressing down, cam handle is rotated relative to pull bar together with cam, cam is when rotating, flange compressing upper gasket on the cam, upper gasket is applied downward pressure, upper gasket is moved downward, because lower gasket is motionless, upper gasket compressing rubber cover like this, make rubber sleeve be subjected to compression swelling, thereby reach the purpose of shutoff.
The present invention rotates the expansion that less angle just can realize rubber sleeve by cam handle, has effectively shortened the set-up time of whole block head, has improved the efficient of shutoff, and has operated very simple and convenient; Simultaneously, the radius of gyration of cam handle is less, can use in narrow and small place in the space.During the circular hole of the different sizes of shutoff, only need pull down nut if desired, the rubber sleeve of changing corresponding size gets final product, and the scope of application is very extensive.
Be arranged side by side two cams in the bottom of described cam handle, this two cams separation is in both sides of pull bar upper end, is connected by straight pin between two cams and the pull bar, and this straight pin is spacing by split pin.Above structure is installed easily on the one hand, and cam handle and cam rotate flexibly relative to pull bar; On the other hand, exert pressure simultaneously, can guarantee the upper gasket stress equalization to upper gasket by two cams side by side, like this rubber sleeve to around expand even, shutoff respond well.
For convenience of processing and fabricating, and help guaranteeing structural strength, described cam and cam handle are structure as a whole.
In order to strengthen reliability to the lower gasket location, below described lower gasket, be provided with first, second two nuts from top to bottom successively, this first, second nut all cooperates with pull rod screw, and described lower gasket is spacing by first nut, and first nut is by second nut lock.
The invention has the beneficial effects as follows:
1, can effectively reduce the set-up time of block head, improve shutoff efficient;
2, the radius that rotates of cam handle is little, can use in that space-constrained is local;
3, the scope of application is wider, changes the hole that rubber sleeve just can be applicable to different sizes;
4, easy to operate, quick, by adjusting the decrement that the position of nut on pull bar can the regulated at will rubber sleeve, to satisfy different shutoff requirements.

Fig. 2 is the structural representation of the right apparent direction of Fig. 1.
Fig. 3 is the structural representation of background technology.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the present invention is made of cam handle 1, straight pin 2, split pin 3, upper gasket 4, pull bar 5, rubber sleeve 6, lower gasket 7, first nut 8, cam 9 and second nut 10, wherein pull bar 5 is a linear pattern pole structure, on the periphery of pull bar 5 lower ends, be processed with screw thread, be set with first nut 8 and second nut 10 by threaded engagement on the thread segment of pull bar 5 lower ends, described first nut 8 is positioned at the top of second nut 10, and both abut against together.Also be set with upper gasket 4, rubber sleeve 6 and lower gasket 7 on described pull bar 5, upper gasket 4 is positioned at the top of rubber sleeve 6, and the end face of the bottom surface of upper gasket 4 and rubber sleeve 6 fits.Described rubber sleeve 6 has certain tapering, the cylindrical of these rubber sleeve 6 lower ends is less than the cylindrical of upper end, and the end face of the bottom surface of rubber sleeve 6 and lower gasket 7 is fitted, and the bottom surface of lower gasket 7 is pressed on first nut 8, spacing by first nut 8, first nut 8 is locked on the pull bar 5 by second nut 10.
As can be known, be provided with two cams 9 above upper gasket 4 from Fig. 1, Fig. 2, these two cams 9 are arranged side by side on sustained height, and two cams 9 are into a single integrated structure with the boss of cam handle 1 bottom.9 separations of described two cams are in the both sides of pull bar 5 upper ends, are connected by the straight pin 2 that laterally wears between two cams 9 and the pull bar 5, and this straight pin 2 is spacing by split pin 3.
Principle of work of the present invention is as follows:
When carrying out shutoff work, rubber sleeve 6 parts with block head stretch in the circular hole that needs shutoff on the engine earlier, the upper end that grasps cam handle 1 then is toward pressing down, cam handle 1 is rotated relative to pull bar 5 around straight pin 2 together with two cams 9, cam 9 is when rotating, flange compressing upper gasket 4 on the cam 9, upper gasket 4 is applied downward pressure, upper gasket 4 is moved downward, because lower gasket 7 is motionless, upper gasket 4 compressing rubbers cover 6 like this, make rubber sleeve 6 be subjected to compression swelling, thereby reach the purpose of shutoff.
