Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 4, the present embodiment provides an intercooler air-tightness test tool for sealing an air pipe a, the intercooler air-tightness test tool includes: the sealing cover comprises a sealing cover 1, a screw rod 2, a sliding block 3 and a locking block 4.

One end surface of the sealing cover 1 is provided with a first elastic rubber layer, and the first elastic rubber layer in this embodiment may be an elastic rubber gasket, and the elastic rubber gasket may be fixedly bonded to the sealing cover 1.

The one end of screw rod 2 with the perpendicular fixed connection in middle part that sealed lid 1 has an terminal surface on first elastic rubber layer, be provided with the screw hole that runs through its both sides terminal surface on the slider 3, the screw hole with 2 threaded connection of screw rod, latch segment 4 with slider 3 is articulated, works as latch segment 4 is relative when slider 3 rotates, the longest limit or the shortest limit of latch segment 4 can with the axis of screw rod 2 is parallel, the length of the longest limit of latch segment 4 is greater than trachea a's internal diameter, the length of the shortest limit of latch segment 4 is less than trachea a's internal diameter.

This intercooler air-tightness test frock when using, can with latch segment 4 passes through trachea a inserts intercooler b's inner chamber, and then toward back the pull screw rod 2 makes latch segment 4 supports tightly under the effect of tension intercooler b's inner wall avoids latch segment 4 reaches slider 3 is relative trachea a rotates, rotates simultaneously sealed lid 1 makes sealed lid 1 is to being close to slider 3's direction slides, and makes sealed lid 1 the latch segment 4 presss from both sides and locates trachea a's both ends, it is right that sealed lid 1 has the one end on first rubber layer trachea a seals, and the operation process is convenient, need not to install locking mechanism in advance.

The embodiment provides a specific implementation manner, one end of the screw rod 2, which is far away from the sealing cover 1, is provided with a limiting hole 2a, a limiting pin (not shown in the figure) is inserted into the limiting hole 2a, and the sliding block 3 slides between the sealing cover 1 and the limiting pin, so that the sliding block 3 is prevented from slipping from the screw rod 2, and the sliding block 3 is prevented from falling into an inner cavity of the intercooler b.

The surface of the locking block 4 is provided with a second elastic rubber layer, specifically, the second elastic rubber layer is elastic rubber sprayed on the surface of the locking block 4, and the second elastic rubber layer can prevent the locking block 4 from scratching the inner cavity of the intercooler b.

In this embodiment, intercooler air-tightness test frock still include handle 5, handle 5 is fixed in sealed lid 1 deviates from a terminal surface of slider 3, handle 5 can make things convenient for the workman to rotate sealed lid 1.

Locking block 4 includes joint board 41 and spacing axle 42, joint board 41 is two, two joint board 41 is obtuse triangle, and two joint board 41's shape and size are all the same, two joint board 41's obtuse angle end all with slider 3 is articulated, and two joint board 41 mutual disposition in slider 3's both sides, and joint board 41's articulated shaft with the axis of screw rod 2 is perpendicular, when joint board 41 rotates, two minor faces of joint board 41 can butt in intercooler b's inner wall, thereby has restricted joint board 41 roll-off trachea a, in this embodiment, every joint board 41's three closed angle all falls into the fillet to avoid the closed angle fish tail intercooler b.

The number of the limiting shafts 42 is two, one of the two ends of the limiting shaft 42 is connected to two of a group of adjacent acute angle ends of the clamping plate 41, the other of the two ends of the limiting shaft 42 is connected to two of another group of adjacent acute angle ends of the clamping plate 41, and the two limiting shafts 42 can limit the maximum angle of the clamping plate 41 swinging towards two sides.

The present embodiment further provides a preferable embodiment, the snap plate 41 is a non-isosceles obtuse triangle, that is, the gravity on both sides of the hinge shaft of the snap plate 41 is unbalanced, and the snap plate 41 is easily deflected under its own gravity, so as to facilitate taking out the locking block 4 from the inner cavity of the intercooler b.

The working principle is as follows: this intercooler air-tightness test frock when using, can with latch segment 4 passes through trachea a inserts intercooler b's inner chamber, and then toward back the pull screw rod 2 makes latch segment 4 supports tightly under the effect of tension intercooler b's inner wall avoids latch segment 4 reaches slider 3 is relative trachea a rotates, rotates simultaneously sealed lid 1 makes sealed lid 1 is to being close to slider 3's direction slides, and makes sealed lid 1 the latch segment 4 presss from both sides and locates trachea a's both ends, it is right that sealed lid 1 has the one end on first rubber layer trachea a seals, and the operation process is convenient, need not to install locking mechanism in advance.
