Description
Technical field
The utility model relates to a kind of unthreaded hole fast plugging device, can be applicable to the aspects such as Engine Block Test.
Background technique
At Engine Block Test and in producing, need to carry out leak test to water channel, oil channel hole etc.During artificial leak test, generally use rubber or polyurethane sheet to be placed on the face of water channel, oil channel hole, then fix by steel plate and screw, thereby realize sealing.Due to use face sealing, all have strict demand to compressing the shapes of steel plate, to prevent other positions interference of itself and motor.Said method needs a large amount of time, and labor intensity is large, has a strong impact on manufacturing efficiency.
Summary of the invention
The purpose of this utility model is to propose a kind of fast plugging device simple in structure, easy to use.
Fast plugging device of the present utility model comprises eccentric mass, setting sleeve, sealing rubber ring and pull bar, and described setting sleeve consists of the boss of body and body upper end, and described boss diameter is greater than the diameter of setting sleeve body; Described setting sleeve is provided with through hole; Described pull bar is through through hole, the top of pull bar is connected with eccentric mass by bearing pin, the bottom of pull bar is provided with horizontal block, and described sealing rubber ring is placed on the setting sleeve body between boss and horizontal block, and the bottom of sealing rubber ring protrudes from setting sleeve body downwards.
In use, sealing rubber ring and pull bar are partly stretched in the unthreaded hole for the treatment of shutoff, and the bottom surface of boss and the end face of unthreaded hole are offseted, then rotate eccentric mass, because making the distance of bearing pin and setting sleeve end face, eccentric mass increases, therefore can under the drive of eccentric mass, move upward by pull bar, now the horizontal block of pull bar bottom will drive sealing rubber ring synchronously to move up, but sealing rubber ring can be subject to stopping of boss bottom surface, sealing rubber ring along continuous straight runs under the compression of horizontal block and boss is expanded, thereby the hole wall close contact with unthreaded hole, realize the shutoff of unthreaded hole.Rotate backward eccentric mass, can make horizontal block move down, reduce the compressive force of the suffered Vertical direction of sealing rubber ring, sealing rubber ring is restored to the original state, the shutoff of contact unthreaded hole.
Further, described setting sleeve body is the inverted round table structure of chap gradually from the bottom to top, like this when horizontal block drives sealing rubber ring to move up, sealing rubber ring not only can be subject to the compressive force at the two ends up and down that horizontal block and boss apply, also can be subject to the thrust laterally that setting sleeve body applies, the amplitude that sealing rubber ring is outwards expanded is larger, and sealing effect is better.
Further, described through hole is provided with convex step in setting sleeve body bottom, in described through hole, is provided with spring, and the bottom surface of the top of described spring and convex step offsets, and the bottom of spring and the end face of described horizontal block offset.When rotating backward eccentric mass, spring can utilize the horizontal block of the pushed down of self like this, makes better sealing rubber ring restore to the original state.
Further, for convenience of operation, the end of described eccentric mass is provided with handle, and handle plays the effect of lever, can make operator utilize very little strength to rotate eccentric mass, realizes shutoff.
Fast plugging device of the present utility model is simple in structure, cost is low, easy to operate, be very suitable for the temporary plugging in unthreaded hole and other holes.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and working principle etc.
Embodiment 1:
As shown in Figure 1, 2, 3, the fast plugging device of the present embodiment comprises eccentric mass 1, setting sleeve 2, sealing rubber ring 3 and pull bar 4, and the end of eccentric mass 1 is provided with handle 5; Described setting sleeve consists of the boss 22 of body 21 and body 21 upper ends, and described boss 22 diameters are greater than the diameter of setting sleeve body 21; Described setting sleeve 2 is provided with vertical through hole 23; Described pull bar 4 is through through hole 23, the top of pull bar 4 is connected with eccentric mass 1 by bearing pin 6, the bottom of pull bar 4 is provided with horizontal block 7, described sealing rubber ring 3 is placed on the setting sleeve body 21 between boss 22 and horizontal block 7, and the bottom of sealing rubber ring 3 protrudes from setting sleeve body 21 downwards.
Described through hole 23 is provided with convex step 24 in setting sleeve body 21 bottoms, in described through hole 23, is provided with spring 8, and the bottom surface of the top of described spring 8 and convex step 24 offsets, and the end face of the bottom of spring 8 and described horizontal block 7 offsets.
In use, sealing rubber ring 3 and pull bar 4 parts are stretched in the unthreaded hole 9 for the treatment of shutoff, and the bottom surface of boss 22 and the end face of unthreaded hole 9 are offseted, then handle with sleeve 5, thereby drive eccentric mass 1 to rotate, because making bearing pin 6 and the distance of setting sleeve end face, eccentric mass 1 increases, therefore can under the drive of eccentric mass 1, move upward by pull bar 4, now the horizontal block 7 of pull bar 4 bottoms will drive sealing rubber ring 3 synchronously to move up, but sealing rubber ring 3 can be subject to stopping of boss 22 bottom surfaces, sealing rubber ring 3 along continuous straight runs under the compression of horizontal block 7 and boss 22 is expanded, thereby the hole wall close contact with unthreaded hole 9, realize the shutoff of unthreaded hole 9.Rotate backward handle 5, can make horizontal block 7 move down, reduce the compressive force of the suffered Vertical direction of sealing rubber ring 3, sealing rubber ring 3 is restored to the original state, the shutoff of contact unthreaded hole 9.
Embodiment 2:
As shown in Figure 4,5, 6, as different from Example 1, in the present embodiment, setting sleeve body 21 is the inverted round table structure of chap gradually from the bottom to top, like this when horizontal block 7 drives sealing rubber rings 3 to move up, sealing rubber ring 3 not only can be subject to the compressive force at the two ends up and down that horizontal block 7 and boss 22 apply, and also can be subject to the thrust laterally that setting sleeve body 21 applies, the amplitude that sealing rubber ring 3 is outwards expanded is larger, and sealing effect is better.
