Description
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 is as shown in Figure 3, is made up of suit rubber sleeve 6, upper gasket 4 and rotary handle 11 successively from the bottom up on pull bar 5 rotary handle 11, pull bar 5, upper gasket 4 and rubber sleeve 6; 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, said 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; Rubber sleeve to stretching in the circular hole is exerted pressure, and makes rubber receive 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 following: 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, and its key is: the bottom surface of said rubber sleeve and lower gasket are fitted, and this lower gasket is spacing by the nut of suit on the pull bar; Above said upper gasket, be provided with cam, 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, 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; Grasp the upper end pressed downward of cam handle then, cam handle is rotated together with the relative pull bar of cam, cam is when rotating; Flange compressing upper gasket on the cam applies downward pressure to upper gasket, and upper gasket is moved downward; Because lower gasket is motionless; Upper gasket compressing rubber cover makes rubber sleeve receive compression swelling like this, thereby reaches the purpose of shutoff.
The present invention rotates the expansion that less angle just can realize rubber sleeve through 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 said cam handle, this two cams separation is in both sides of pull bar upper end, is connected through 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 the relative pull bar of cam handle and cam rotates flexibly; On the other hand, exert pressure to upper gasket simultaneously, can guarantee the upper gasket stress equalization through two cams side by side, like this rubber sleeve to around expand evenly shutoff respond well.
Processing and fabricating for ease, and help guaranteeing structural strength, said cam and cam handle are structure as a whole.
In order to strengthen reliability to the lower gasket location; Below said 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 said lower gasket is spacing by first nut, and first nut is through 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, through the adjustment position of nut on pull bar can the regulated at will rubber sleeve decrement, to satisfy different shutoff requirements.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Like Fig. 1, shown in Figure 2; The present invention is made up 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, is processed with screw thread, is set with first nut 8 and second nut 10 through threaded engagement on the thread segment of pull bar 5 lower ends; Said first nut 8 is positioned at the top of second nut 10, and both abut against together.On said pull bar 5, also be set with upper gasket 4, rubber sleeve 6 and lower gasket 7, 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.Said 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 through second nut 10.
From Fig. 1, Fig. 2, can know, above upper gasket 4, be provided with two cams 9, 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 said two cams are in the both sides of pull bar 5 upper ends, are connected through 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 following:
When carrying out shutoff work, rubber sleeve 6 parts with block head stretch in the circular hole that needs shutoff on the engine earlier, grasp the upper end pressed downward of cam handle 1 then; Cam handle 1 is rotated around straight pin 2 relative pull bars 5 together with two cams 9, and cam 9 is when rotating, and the flange on the cam 9 is oppressed upper gasket 4; 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 receive compression swelling, thereby reach the purpose of shutoff.
