Technical Field
The utility model belongs to the technical field of the automobile inspection work piece and specifically relates to an internal expanding device that leaks hunting.
Background
After the existing automobile engine is manufactured, a leakage detection process is needed, so that when the engine is subjected to leakage detection, a throttle valve of the engine needs to be sealed. When present automobile engine leaks hunting, adopt the sealing that rises outward, directly plug into the throttle valve, seal, this kind of sealed mode for can produce the interference with it when the throttle valve need be opened, but the throttle valve inner arm is comparatively smooth, and the sealed easy pop-up that rises outward, and is not durable.
Therefore, improvements to the prior art are yet to be made.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an internal expanding device that leaks hunting aims at solving current external expanding type when sealing engine valve, and the external expanding is sealed pops out easily, not enough durable technical problem.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the inner expansion leak detection device comprises an inner expansion end cover covered on an engine throttle valve, a leather cup seal and a toggle switch, wherein the leather cup seal is fixedly installed in the inner expansion end cover, the toggle switch is communicated with the leather cup seal through a pipeline, and the toggle switch controls the on-off of gas to control the inner expansion and contraction of the leather cup seal.
The internal expansion leakage detection device is characterized in that the toggle switch is provided with a 90-degree air pipe joint.
The inner expansion leakage detection device is characterized in that the leather cup is fixed in the inner expansion end cover through a screw in a sealing mode.
The internal expansion leakage detection device is characterized in that the screw is a countersunk head inner hexagonal screw.
The internal expansion leak detection device is characterized in that a connecting through hole for connecting a leak detector is formed in the internal expansion end cover.
The inner expansion leakage detection device is characterized in that a boss used for increasing friction force is arranged at the end part of the outer circumference of the throttle valve.
Has the advantages that: the utility model fixes the leather cup in the inner expansion end cover in a sealing way, and then is communicated with the toggle switch through the pipeline, so that after the inner expansion end cover is covered on the throttle valve, the toggle switch opens the pipeline to be communicated with the leather cup in a sealing way, and gas enters the leather cup to be sealed to realize inner expansion, thereby realizing the sealing with the throttle valve; the inner expansion sealing mode utilizes the boss at the end part of the throttle valve to increase the friction force, does not have the phenomenon of popping out when in use, has good sealing performance, can not interfere with the throttle valve when in need of opening, and is durable.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples.
As shown in fig. 1-2, the utility model discloses an internal expanding leak hunting device, it includes buckle closure at the internal expanding end cover 1, the sealed 2 and the toggle switch 3 of leather cup of engine air throttle 4, the sealed 2 fixed mounting of leather cup is in internal expanding end cover 1, and toggle switch 3 passes through the pipeline and seals 2 intercommunications with the leather cup, by toggle switch 3 control gas break-make, realizes controlling the internal expanding and the shrink of sealed 2 of leather cup.
After the structure of the oil-gas separator is adopted, the utility model discloses a set the internal expanding end cover with the internal expanding device, so with the internal expanding end cover buckle closure behind the throttle valve of engine in the time of leaking hunting, toggle switch control gas and install the sealed intercommunication of leather cup in the internal expanding end cover for the leather cup is sealed to be realized the internal expanding, it is sealed with the butt joint department of internal expanding end cover with the throttle valve, this kind of sealed mode can not have pop-out phenomenon, and sealing performance is good, also can not interfere with it when the throttle valve need be opened, and it is sealed more durable than the external expanding formula.
In the internal expansion leakage detection device, the toggle switch 3 is provided with a 90-degree air pipe joint 5, so that the toggle switch 3 can be communicated with an external air supply device through the air pipe joint 5; preferably, the toggle switch 3 is fixed on the inner expansion end cover through a switch bracket 6.
The internal expansion leakage detection device is characterized in that the leather cup seal 2 is fixed in the internal expansion end cover 1 through a screw 7, so that the leather cup seal can be stably fixed with the internal expansion end cover and has the anti-pop-up performance.
The internal expansion leakage detection device is characterized in that the screw 7 is a countersunk hexagon socket head cap screw.
The inner expansion leakage detection device is characterized in that a connecting through hole 10 for connecting a leakage detector is formed in the upper surface of the inner expansion end cover 1; the through hole 10 can be connected with a leakage detector to realize the air tightness detection of the engine.
In the internal expansion leakage detection device, the boss 40 for increasing friction force is arranged at the end part of the outer circumference of the throttle valve 4, so that the friction force of the internal expansion end cover can be increased by the contact of the boss 40 and the leather cup seal 2, the anti-pop-up effect is achieved, and the sealing performance is enhanced.
The utility model fixes the leather cup in the inner expansion end cover in a sealing way, and then is communicated with the toggle switch through the pipeline, so that after the inner expansion end cover is covered on the throttle valve, the toggle switch opens the pipeline to be communicated with the leather cup in a sealing way, and gas enters the leather cup to be sealed to realize inner expansion, thereby realizing the sealing with the throttle valve; the inner expansion sealing mode utilizes the boss at the end part of the throttle valve to increase the friction force, does not have the phenomenon of popping out when in use, has good sealing performance, can not interfere with the throttle valve when in need of opening, and is durable.
