Detailed Description

The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 3.

In the first embodiment, the technical scheme for solving the problem is that the utility model can be placed at a proper position by contacting the bottom plate 1 with the ground when in use; the inlet end of the rubber heat-resistant pipe 6 is convenient to be sleeved with an exhaust pipe of a motor vehicle; the first spring one-way valve 14 is arranged to only allow gas to flow from the direction of the metal transverse pipe 4 to the vertical cylinder 2, but not allow the gas in the vertical cylinder 2 to flow into the metal transverse pipe 4; a second spring check valve 15 is provided to allow gas to flow only from the shaft 2 to the bag 3 and not to allow gas in the bag 3 to flow back to the standpipe. When collecting tail gas, earlier through height adjusting device adjusting slide 19, and then make rubber heat-resistant pipe 6 be in same height with the blast pipe of motor vehicle to rubber heat-resistant pipe 6 and blast pipe butt joint, and can guarantee that gas flow is unobstructed, ensure tail gas collection efficiency.

After the butt joint of the rubber heat-resistant pipe 6 and the exhaust pipe is completed, tail gas collection can be started, and the butt joint method specifically comprises the following steps: the motor vehicle is started to produce tail gas, and the driving motor 8 is started so as to drive the piston sheet 11 to perform vertical reciprocating movement along the vertical cylinder 2, and then the tail gas of the motor vehicle is rapidly guided into the collecting bag 3. The driving motor 8 on the vertical rod 7 can drive the rotating rod 23 to rotate through the output shaft 9, the rotating rod 23 rotates to drive the plug rod 12 to perform vertical reciprocating movement along the through hole on the vertical cylinder 2 through the cooperation of the inserting rod 10 and the driving ring 13, and then the piston sheet 11 fixedly connected with the plug rod 12 synchronously performs vertical reciprocating movement along the vertical cylinder 2. Since the first spring check valve 14 only allows gas to flow from the metal cross tube 4 to the vertical tube 2, and the second spring check valve 15 only allows gas to flow from the vertical tube 2 to the collecting bag 3, the vertical reciprocating movement of the fixed piston sheet 11 in cooperation with the first spring check valve 14 and the second spring check valve 15 intervenes in the gas flow direction; when the piston sheet 11 moves upwards, exhaust gas generated by the motor vehicle is rapidly pumped, so that the exhaust gas passes through the rubber heat-resistant pipe 6, the joint 5 and the metal transverse pipe 4 in sequence and is pumped into the vertical cylinder 2; when the piston plate 11 moves downwards, the exhaust gas pumped into the vertical pipe is rapidly pressed and guided into the collecting bag 3, and the exhaust gas collecting efficiency is greatly improved.

The height adjusting device can drive the screw 21 to drive the threaded sleeve 20 through the rotation of the rotating shaft 18, so that the sliding block 19 can move vertically along the sliding rod 16, and along with the vertical movement of the sliding block 19, the vertical cylinder 2, the metal transverse pipe 4, the joint 5 and the rubber heat-resistant pipe 6 can also move vertically synchronously, so that the rubber heat-resistant pipe 6 can be sleeved with an exhaust pipe of a motor vehicle.

In the second embodiment, on the basis of the first embodiment, when the height adjusting device is used, the rotating hand wheel 22 can be rotated to drive the rotating rod connected between the supporting block 17 and the bottom plate 1 to rotate, and when the rotating shaft 18 rotates clockwise, the screw 21 integrally arranged with the rotating shaft 18 drives the sliding block 19 to move upwards along the sliding rod 16 through the matching action of the screw 21 and the screw sleeve 20, so as to drive all parts on the left side of the sliding block 19 to integrally and synchronously move upwards; a corresponding counter-clockwise rotation of the spindle 18 will cause the slider 19, i.e. the parts on the left side of the slider 19, to move synchronously downwards. The vertical hole on the sliding block 19 facilitates the sliding block 19 and the sliding rod 16 to realize vertical sliding fit.
