Description

Tightness detection tool

Technical Field

The utility model belongs to the technical field of car warm braw system, in particular to leakproofness detects frock.

Background

The tightness detection is one of the very important links in the production and the manufacture of the automobile warm air system, and is directly related to whether the water inlet pipe and the water outlet pipe are leaked or not. In the warm air production process, the interval of some business turn over water pipes is less, and the leakproofness testing mode commonly used is, seals through single seal structure, changes the interval of business turn over water pipe like this easily, changes business turn over water pipe's trend.

SUMMERY OF THE UTILITY MODEL

To the technical problem who exists among the prior art, the utility model provides a leakproofness detects frock can prevent into outlet pipe trend and warp.

In order to solve the technical problem, the utility model discloses a technical scheme is:

the utility model provides a leakproofness detects frock, includes cylinder, ventilation piece, connecting plate and seal assembly, the telescopic link of cylinder is connected with the piece of ventilating, the both ends of ventilation piece are equipped with the air vent respectively, the both ends of connecting plate are equipped with the through-hole that communicates with the air vent respectively, two seal assembly connects respectively in the through-hole department of connecting plate.

Preferably, the sealing assembly comprises a sealing plug, a first gasket, a second gasket and a bolt, the bolt sequentially penetrates through the first gasket, the sealing plug and the second gasket and is connected to the connecting plate, and air holes communicated with the through holes are formed in the second gasket and the sealing plug so as to allow air to expand the sealing plug.

Preferably, the sealing plug is made of rubber.

Preferably, the cylinder body of the cylinder is connected to the bottom plate, and the telescopic rod of the cylinder is connected with the ventilation block through a screw.

Compared with the prior art, the utility model discloses the beneficial effect who has is: the utility model discloses a two seal assembly are connected to a cylinder and are sealed to inlet tube and outlet pipe, can not change the interval of inlet tube and outlet pipe, save time, laborsaving, have improved operating personnel's work efficiency, have reduced workman's working strength.

Detailed Description

So that those skilled in the art can better understand the technical solution of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the embodiment of the utility model discloses a leakproofness detects frock, including cylinder 1, ventilation piece 2, connecting plate 3 and seal assembly, cylinder 1's telescopic link is connected with ventilation piece 2, and ventilation piece 2's both ends are equipped with air vent 21 respectively, and connecting plate 3's both ends are equipped with the through-hole that communicates with air vent 21 respectively, and two seal assembly connect respectively in connecting plate 3's through-hole department to let in gas and make seal assembly inflation, can seal inlet tube 11 and outlet pipe 12.

In this embodiment, sealing assembly includes sealing plug 4, first gasket 5, second gasket 6 and bolt 7, and bolt 7 passes first gasket 5, sealing plug 4 and second gasket 6 in proper order and is connected on connecting plate 3, is equipped with the gas pocket with the through-hole intercommunication in second gasket 6 and the sealing plug 4 to let in gas expansion sealing plug 4. The sealing plug 4 is made of rubber.

In this embodiment, the cylinder body of the cylinder 1 is connected to the bottom plate 8 through the mounting plate 9, and the telescopic rod of the cylinder 1 is connected to the ventilation block 2 through the screw 10.

The utility model provides a working process of leakproofness detection frock is, and bottom plate 8 has installed and has put at the workstation, and seal assembly inserts the one end of inlet tube and the one end of outlet pipe respectively, then opens cylinder 1, and cylinder 1's telescopic link pulling seal assembly makes the sealing plug swell and seals inlet tube 11 and outlet pipe 12, then lets in gas from air vent 21 again, detects the pressure value through the gas detection appearance and sees the gas leakage volume.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
