Description
Technical field
Air-leakage test technical field is the utility model is related to, more particularly to a kind of 90 degree of buttock line camera air-leakage tests
Device.
Background technology
With the fast development of automobile industry, car rule level camera is using more and more extensive, and camera species is also increasingly
It is more.The difference of vehicle and the difference of appellative function cause camera installation site also different, buttock line and camera body Cheng Zhi
The traditional camera of line 180 degree can not fully meet the demand of people, and buttock line and camera body are into 90 degree of shapes at present
Camera is frequently used.Because car rule level camera is typically mounted on body exterior, the air-tightness of its own is particularly important,
If according to traditional 180 degree camera air-tightness device mentality of designing make 90 degree cameras test device for air tightness, understand because
The particularity of 90 degree of camera buttock line structures causes the stability of test device for air tightness and sealing poor, is also easy to produce and surveys by mistake,
Have a strong impact on production line efficiency.
Utility model content
The utility model is in order to solve the above-mentioned technical problem, there is provided one kind is dedicated for 90 degree of buttock line camera air-tightness
The device of detection, avoid test device and leaked air in air-leakage test phenomenon, effectively increase its stability, reduce and miss
The probability of survey.
A kind of 90 degree of buttock line camera air-tightness detection devices, including upper module, lower module and fixture sealing ring；Upper module
The die cavity and the line outlet groove vertical with die cavity, die cavity and line outlet groove phase for accommodating 90 degree of buttock line cameras are formed after being closed with lower module
It is intercommunicated；Fixture sealing ring is placed in die cavity upper end porch, for sealing die cavity between upper module and lower module；Folder
Tool sealing ring carries out thickening processing in the relevant position contacted with camera buttock line, and the thickening of sealing ring, which is handled, causes module up and down
Amount of compression is added during pressing, further improves device sealing.
Further, fixture sealing ring is sealed against each other with die cavity upper end entrance shape and matched, and strengthens sealing effectiveness.
Further, the fixture sealing ring is elastomeric material, preferably silica gel material or quality of rubber materials, is easy to play more preferably
Sealing effectiveness.
Further, upper module is fixedly connected with lower module by fixture, fixes its relative position, is easy to application outer
Power.
Further, cavity bottom is provided with air admission hole, and the air admission hole is connected by pipeline with aerating device.
Further, aerating device is provided with pressure regulating valve, controls aerating device defeated to die cavity inside by pressure regulating valve
Supply gas the amount of body, realize that die cavity internal pressure is controllable.
Further, die cavity is communicated with differential pressure pickup, is easy to during air-leakage test real-time monitoring type intracavitary portion
The change of pressure.
The advantageous effects that the present invention is played are as follows：
Compared with prior art, a kind of 90 degree of buttock line camera air-tightness detection devices are effective disclosed in the utility model
The stability of testing engineering is improved, makes device that there is better seal effect, effectively avoids in detection process and leaks
Gas phenomenon, the probability surveyed by mistake, and 90 degree of buttock line cameras of the compatible more money different subjects of the air-tightness detection device are reduced, are fitted
It is wider with scope.
Brief description of the drawings
Fig. 1 is attachment structure schematic diagram of the present utility model.
Brief description of the drawings：1- upper modules, 2- lower modules, 3- die cavities, 4- fixture sealing rings.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention are more
Easily it is readily appreciated by one skilled in the art, so as to make apparent define to protection scope of the present invention.
Embodiment 1：
Present embodiments provide a kind of 90 degree of buttock line camera air-tightness detection devices, including upper module 1, lower module 2 and
Fixture sealing ring 4；Upper module 1 and lower module 2 form the die cavity 3 that accommodates 90 degree of buttock line cameras and vertical with die cavity 3 after closing
Line outlet groove, die cavity 3 is interconnected with line outlet groove, and die cavity 3 is also communicated with the pressure difference for monitoring the change of its internal pressure in real time
Sensor.Fixture sealing ring 4 is placed in the upper end porch of die cavity 3, fixture sealing ring 4 between upper module 1 and lower module 2
Seal against each other and match with the upper end entrance shape of die cavity 3, for sealing die cavity 3, ensure that the good air-tightness of detection means.Fixture
Sealing ring 4 carries out thickening processing in the relevant position contacted with camera buttock line, causes caused during module pressing up and down squeeze
Pressure amount increases, and further increases the sealing of device.In addition, the bottom of die cavity 3 is provided with air admission hole, air admission hole is by pipeline with filling
Device of air is connected, and pressure regulating valve is additionally provided with aerating device, by pressure regulating valve aerating device can be controlled defeated to the inside of die cavity 3
Supply gas the content of body, realize the controllable of the internal pressure of die cavity 3.
Embodiment 2：
The present embodiment and the difference of embodiment 1 are that above-mentioned fixture sealing ring 4 is prepared by elastomeric material, such as silica gel
