Description
Technical Field
[0001] The present invention relates to the technical field related to motor vehicle detection, and in particular to an exhaust gas collection device for motor vehicle detection. Background Art
[0002] The exhaust we are talking about now mostly refers to automobile exhaust, that is, the exhaust gas discharged from the exhaust pipe of the car. Automobile exhaust is another major factor in air pollution. Automobile exhaust contains carbon monoxide, nitrogen oxides and other solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body.
[0003] Exhaust gas emitted by motor vehicles or other equipment during their operation. In modern civilization, cars have become an indispensable means of transportation for mankind. However, with the rapid development of the automobile industry and the continuous increase in automobile production and ownership, cars have also brought about air pollution, namely automobile exhaust pollution.
[0004] The main purpose of collecting exhaust gas is to check whether the exhaust gas of automobiles meets the road standards. However, when motor vehicles are running normally, the exhaust gas collected will be mixed with air, which makes the test value inaccurate. However, there will be no rising problem when the car is idling. Summary of the invention
[0005] The purpose of the present invention is to provide an exhaust gas collection device for motor vehicle detection to solve the problems raised in the above background technology.

[0007] As a further solution of the present invention: a second connector is arranged in the side wall of the gas cylinder, and a first connecting hose is connected between the second connector and the first connector.
[0008] As a further solution of the present invention: a handle is fixedly connected to the top of the grip rod.
[0009] As a further solution of the present invention: one end of the grip rod close to the handle is fixedly connected to a collection bottle mounting port.
[0010] As a further solution of the present invention: a fourth connector is fixedly connected to the mounting port of the collection bottle, and a second connecting hose is connected between the fourth connector and the third connector.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention compresses and discharges the gas in the device through a compressible air bag, and then vacuum-sucks the exhaust gas generated by the car, thereby preventing the outer wall gas from mixing into the car exhaust gas.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.
[0019] In one embodiment of the present invention, see Figure 1 to Figure 5 , an exhaust gas collection device for motor vehicle detection, comprising a grip rod 1, a connecting pipe 3 is fixedly connected to the bottom of the grip rod 1, one end of the connecting pipe 3 is fixedly connected to a mounting seat 5, a mounting head 6 is internally threadedly connected to the mounting seat 5, a sealing plug 7 is fixedly connected to the mounting head 6, an air inlet 8 is arranged in the sealing plug 7, a first one-way valve 24 is arranged in the connecting pipe 3, a first connecting head 4 is fixedly connected to the other end of the connecting pipe 3, a fixed pipe 9 is fixedly connected to the grip rod 1, a sliding block 10 is slidably connected to the fixed pipe 9, a spring 11 is sleeved on the outer wall of the fixed pipe 9, a telescopic rod 12 is fixedly connected to the sliding block 10, an anti-skid plate 13 is rotatably connected to the bottom of the telescopic rod 12, a pedal 15 is rotatably connected to the anti-skid plate 13, and the anti-skid plate An air cylinder 14 is fixedly connected to the upper surface of the handle 13, an air bag 16 is installed between the air cylinder 14 and the pedal 15, a reed 17 connected between the pedal 15 and the anti-slip plate 13 is arranged in the air bag 16, a third connector 20 is arranged in the air cylinder 14, and a second one-way valve 25 is arranged in the third connector 20; a second connector 18 is arranged in the side wall of the air cylinder 14, a first connecting hose 19 is connected between the second connector 18 and the first connector 4, a handle 2 is fixedly connected to the top of the grip 1, an end of the grip 1 close to the handle 2 is fixedly connected to a collection bottle mounting port 21, a fourth connector 22 is fixedly connected to the collection bottle mounting port 21, and a second connecting hose 23 is connected between the fourth connector 22 and the third connector 20; When the present invention is in use, the staff can hold the grip rod 1 through the handle 2, so that the staff can operate the equipment. When in use, the staff first places the anti-skid plate 13 under the exhaust port of the car. At this time, the spring 11 pushes the sliding block 10 to the lowest point, that is, the relative distance between the anti-skid plate 13 and the sealing plug 7 is the largest. Then the staff can press the grip rod 1 according to the height difference between the exhaust port of the car and the ground, and the grip rod 1 drives the fixed tube 9 to press down. At this time, the anti-skid plate 13 contacts the ground, and then the telescopic rod 12 is limited. At this time, the sliding block 10 and the fixed tube 9 slide relative to each other, thereby compressing the spring 11 clamp. At this time, the grip rod 1 will drive the sealing plug 7 to descend synchronously, thereby adjusting the height of the sealing plug 7. At the same time, the angle of the grip rod 1 can be adjusted by the rotation connection between the telescopic rod 12 and the anti-skid plate 13. The grip rod 1 drives the sealing plug 7 to rotate relatively, so that the sealing plug 7 is inserted into the exhaust pipe of the car at different heights and angles. Then the staff can adjust the angle of the grip rod 1 by the rotation connection between the telescopic rod 12 and the anti-skid plate 13. The grip rod 1 drives the sealing plug 7 to rotate relatively, so that the sealing plug 7 is inserted into the exhaust pipe of the car at different heights and different angles. Before starting, the pedal 15 is stepped on, the pedal 15 rotates and presses down, and compresses the reed 17, and at the same time compresses the airbag 16. At this time, the first one-way valve 24 is closed, the second one-way valve 25 is opened, and the gas in the airbag 16 is discharged along the third connector 20. After that, when the car is started, the staff releases the pedal 15. At this time, the pedal 15 is reset under the push of the reed 17, and drives the airbag 16 to deploy. When the airbag 16 is deployed, the first one-way valve 24 is closed, the second one-way valve 25 is opened, and the exhaust gas in the exhaust pipe is discharged along the third connector 20. Driven by the air pressure difference, the exhaust gas enters the connecting pipe 3 through the air inlet 8 in the sealing plug 7, and then flows into the air cylinder 14 through the first connecting hose 19, so that the exhaust gas is temporarily stored in the airbag 16. When the car stops running, the staff installs the collection bottle on the collection bottle installation port 21 and steps on the pedal 15 again. The pedal 15 compresses the airbag 16 again. At this time, the first one-way valve 24 is closed, and the second one-way valve 25 is opened. The exhaust gas in the airbag 16 flows into the collection bottle along the second connecting hose 23, thereby completing the collection.
[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
