Detailed description of the invention
Understandable for enabling the above-mentioned purpose of invention, feature and advantage to become apparent from, below the specific embodiment of the present invention is described in detail。
Elaborate a lot of detail in the following description so that fully understanding the present invention, but the present invention can also adopt other to be different from alternate manner described here to be implemented, those skilled in the art can do similar popularization when without prejudice to intension of the present invention, and therefore the present invention is not by the restriction of following public specific embodiment。
As depicted in figs. 1 and 2, the invention provides a kind of oil level gauge of engine hole sealing device, comprising:
Pull bar 1, has sealed end 11 and link 12, is provided with air-filled pore 13 in described pull bar 1, and the surface configuration of described pull bar 1 has the connecting hole 14 communicated with described air-filled pore 13；
Sleeve 2, is set in the outside of described pull bar 1, and is slidably matched with described pull bar 1, and described sealed end 11 and described link 12 are respectively positioned on outside described sleeve 2；
Gas-tpe fitting 3, is connected with described sleeve 2, and the endoporus 31 of described gas-tpe fitting 3 is connected with described connecting hole 14, and above-mentioned being connected can be realized by welding or threaded mode；
Sealing shroud 4, is set in outside described sealed end 11, and the end face of described sealing shroud 4 and described sleeve 2 offset, and it will be apparent to those skilled in the art that sealing shroud 4 is made up of elastomeric material such as rubber etc., and it can deform under pressurized；
Handle 5, has cam part 51, and described cam part 51 is rotationally connected with described link 12。
During use, first sealed end 11 and sealing shroud 4 are inserted in oil rule hole, the end face of sleeve 2 and oil rule hole offset, rotary handle 5 makes pull bar be directed away from the direction motion in oil rule hole relative to sleeve 2 again, now sealing shroud 4 is deformed thus being blocked in oil rule hole, then pass through gas-tpe fitting 3 to connect source of the gas and inflate in engine oil channel, carry out engine oil channel air tightness test after having inflated, tested rear rotary handle 5 and made sealing shroud 4 resile to extract sealed end 11 and sealing shroud 4 smoothly in oil rule hole。
The sealed end 11 of the pull bar 1 of oil level gauge of engine hole provided by the invention sealing device is arranged with sealing shroud 4, first sealed end 11 and sealing shroud 4 are inserted in oil rule hole during use, the end face of sleeve 2 and oil rule hole offset, rotary handle 5 makes pull bar 1 be directed away from the direction motion in oil rule hole relative to sleeve 2 again, now sealing shroud 4 is deformed, thus being blocked in oil rule hole, reaching the purpose in canned motor oil rule hole。
In order to prevent the process middle sleeve 2 of oil level gauge of engine hole sealing device Reusability from wearing and tearing, the oil level gauge of engine hole sealing device of the present invention may also include pad 6, the end face of the contiguous described handle 5 of described sleeve 2 is provided with groove 21, described pad 6 is arranged in described groove 21, and described pad 6 and described cam part 51 offset, so, cam part 51 directly contacts with pad 6, can change easily after pad 6 abrasion。
Preferably, described pad 6 is plastic material, to provide certain elastic force。
In order to the rotation making handle 5 is more flexible, described cam part 51 is rotationally connected by bearing pin 7 and described link 12, and described bearing pin 7 is positioned in described cam part 51 by a split pin 8。
In order to be connected on sleeve 2 by gas-tpe fitting 3 more easily, described gas-tpe fitting 3 is threadeded with described sleeve 2。
In order to ensure the air-tightness of oil level gauge of engine hole sealing device self, described sleeve 2 and the inwall of described pull bar 1 socket are additionally provided with sealing ring 9。
Further, described sealing ring 9 includes two, and is arranged on the both sides of described sleeve 2 and described gas-tpe fitting 3 connecting portion。
For more convenient sealing shroud 4 stress and deformation, described sealed end 11 being provided with hoop projection 111, one end of described sealing shroud 4 and described hoop projection 111 offset, and the other end of described sealing shroud 4 and described sleeve 2 offset。
Although the present invention is described in conjunction with above example, but the present invention is not limited to above-described embodiment, and it being only limited by the restriction of claims, it easily can be modified and change by those of ordinary skill in the art, but and without departing from the essential idea of the present invention and scope。
