To determine the emission standards and identify the harmful substances in the black smoke, it is generally collected for testing.
[0003] Currently, the exhaust gas of motor vehicles is centrally collected and then put into a detection device for detection. However, in this split-type collection and detection method, other gases are easily mixed into the motor vehicle exhaust gas, resulting in a reduction in detection accuracy and inconvenience in use. Or the collecting pipe is directly placed into the automobile exhaust pipe for collection. However, during the exhaust process, the strong exhaust gas will blow the collecting pipe away. Therefore, a motor vehicle black smoke detection device is needed to solve the above technical problems. Summary of the Utility Model

One side of the detection device body is provided with a connecting pipe. The end of the connecting pipe away from the detection device body is fixedly connected with a connecting head. The end of the connecting head is fixedly connected with an intake pipe. A tail pipe is arranged outside the intake pipe. A clamping mechanism is arranged on the side of the connecting pipe away from the detection device body.
[0006] The clamping mechanism includes a plurality of groups of hinged blocks circumferentially fixedly connected to the outside of the intake pipe.

One side of each slider away from the intake pipe is hinged to a hinged plate, and the other end of the hinged plate is hinged to the clamping plate. A straight rod is fixedly connected to one side of each slider away from the tail pipe, and the other ends of the straight rods are commonly fixedly connected to a circular ring.
[0007] Preferably, an auxiliary mechanism is provided on the side of the intake pipe away from the detection device body. The auxiliary mechanism includes a rotating ring rotatably connected to the side of the ring away from the intake pipe. A set of second chutes are circumferentially formed on the outer side of the connection head. Arc-shaped grooves are formed on one side of each of the second chutes.

[0012] Beneficial effects:
[0013] Compared with the prior art, the motor vehicle black smoke detection device has the following beneficial effects:
[0014] First, by pushing the ring towards the intake pipe side in the present utility model, the ring drives the straight rod to move, the slider drives the bottom end of the hinge plate to move towards the tail pipe side, the top end of the hinge plate moves upward, and the clamping plate is lifted.

[0021] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.
[0022] As Figures 1 to 4 shown, a motor vehicle black smoke detection device includes a detection equipment body 1, and a connecting pipe 2 is provided on one side of the detection equipment body 1. The connection between the detection equipment body 1 and the connecting pipe 2 is detachable, and the connecting pipe 2 is a telescopic pipe, which facilitates the disassembly and replacement of the connecting pipe 2, and the telescopic pipe can be adapted to different scenario requirements. One end of the connecting pipe 2 away from the detection equipment body 1 is fixedly connected with a connector 3, the end of the connector 3 is fixedly connected with an intake pipe 4, a tail pipe 5 is arranged outside the intake pipe 4, and a clamping mechanism 6 is arranged on one side of the connecting pipe 2 away from the detection equipment body 1;
[0023] The clamping mechanism 6 includes several groups of hinge blocks 60 circumferentially fixed on the outer side of the intake pipe 4. A clamping plate 61 is provided between each group of hinge blocks 60. Clamping blocks 62 are fixedly connected to one end of each clamping plate 61 close to the tail pipe 5. The clamping blocks 62 are all arc-shaped blocks, and a side friction pattern is provided on the side of each clamping block 62 close to the tail pipe 5. The arc-shaped clamping blocks 62 are more convenient for fitting with the tail pipe 5, and at the same time, the friction pattern is beneficial to improving the friction force. One side of each clamping plate 61 is fixedly connected with a first shaft rod 63, and the other end of the first shaft rod 63 is rotatably connected to the hinge block 60. The side of each clamping plate 61 far from the first shaft rod 63 is fixedly connected with a second shaft rod 64, and the other end of the second shaft rod 64 is rotatably connected to the hinge block 60. A torsion spring 65 is sleeved on the outer side of each second shaft rod 64, and both ends of the torsion spring 65 are fixedly connected to the second shaft rod 64 and the hinge block 60 respectively. A group of first chutes 66 are circumferentially provided on the outer side of the intake pipe 4, and sliders 67 are slidably connected in the first chutes 66. The first chutes 66 are T-shaped grooves, and the sliders 67 are T-shaped blocks. The design of the first chutes 66 and the sliders 67 plays a role in limiting the hinge plate 68. Hinge plates 68 are hinged to the sides of the sliders 67 far from the intake pipe 4, and the other ends of the hinge plates 68 are hinged to the clamping plates 61. Straight rods 69 are fixedly connected to the sides of the sliders 67 far from the tail pipe 5, and a circular ring 690 is fixedly connected to the other ends of the straight rods 69 together.
[0024] During operation, when the circular ring 690 is pushed towards the intake pipe 4, the circular ring 690 drives the straight rod 69 to move, the straight rod 69 drives the slider 67 to slide in the first chute 66, the slider 67 drives the bottom end of the hinge plate 68 to move towards the tail pipe 5, and the top end of the hinge plate 68 moves upward, jacking up the clamping plate 61. At this time, each clamping plate 61 is in an open state, and the torsion spring 65 is deformed under force. Then, the intake pipe 4 is inserted into the tail pipe 5, and the circular ring 690 is released. Under the action of the torsion spring 65, the clamping plate 61 rotates towards the side close to the tail pipe 5 until the clamping block 62 clamps the tail pipe 5. At this time, the intake pipe 4 can be stabilized. Furthermore, the device realizes the stability of the intake pipe 4 by putting the intake pipe 4 into the tail pipe 5 and using multiple clamping plates 61 to clamp the tail pipe 5, avoiding the phenomenon that the intake pipe 4 detaches from the tail pipe 5, and realizing the integration of gas collection and detection, avoiding the mixing of other gases in the tail gas, being beneficial to improving the detection accuracy, and being convenient for use.
[0025] On one side of the intake pipe 4 away from the detection device body 1, there is an auxiliary mechanism 7. The auxiliary mechanism 7 includes a rotating ring 71 rotatably connected to the side of the ring 690 away from the intake pipe 4. A group of second chutes 72 are circumferentially formed on the outer side of the connecting head 3. At one end of the second chutes 72 away from the tail pipe 5, buffer pads 8 are fixedly connected, and the buffer pads 8 are all in contact with the limiting rods 74. The design of the buffer pads 8 plays a buffering role. Arc-shaped grooves 73 are formed on one side of the second chutes 72. A group of limiting rods 74 are circumferentially fixedly connected to the inner side of the rotating ring 71, and the ends of the limiting rods 74 all extend into the second chutes 72.
[0026] During operation, before the intake pipe 4 is inserted into the tail pipe 5, press the ring 690 so that the plurality of clamping plates 61 are in an open state. While pressing the ring 690, the ring 690 drives the rotating ring 71 to move, and the rotating ring 71 drives the limiting rods 74 to slide in the second chutes 72. When the rotating ring 71 is rotated, the rotating ring 71 drives the limiting rods 74 to turn into the arc-shaped grooves 73. At this time, release the ring 690, and the plurality of clamping plates 61 can be stably kept in an open state. Then insert the intake pipe 4 into the tail pipe 5, and then rotate the rotating ring 71 in the reverse direction. The rotating ring 71 drives the limiting rods 74 to turn from the arc-shaped grooves 73 into the second chutes 72. Under the action of the torsion spring 65, the plurality of clamping plates 61 clamp the tail pipe 5. Therefore, this structure can be used more conveniently without always keeping the state of pressing the ring 690 during the process of inserting the intake pipe 4 into the tail pipe 5.
[0027] Working principle: During operation, the ring 690 is pushed towards the intake pipe 4. The ring 690 drives the straight rod 69 to move. The straight rod 69 drives the slider 67 to slide within the first chute 66. The slider 67 drives the bottom end of the hinge plate 68 to move towards the tail pipe 5 side, and the top end of the hinge plate 68 moves upward, lifting the clamping plate 61. At this time, each clamping plate 61 is in an open state, and the torsion spring 65 deforms under force. At the same time, the ring 690 drives the rotating ring 71 to move. The rotating ring 71 drives the limiting rod 74 to slide within the second chute 72. When the rotating ring 71 is rotated, the rotating ring 71 drives the limiting rod 74 to turn into the arc-shaped groove 73. At this time, when the ring 690 is released, multiple clamping plates 61 can be stably kept in an open state. Then, the intake pipe 4 is placed into the tail pipe 5, and then the rotating ring 71 is rotated in the reverse direction. The rotating ring 71 drives the limiting rod 74 to rotate from the arc-shaped groove 73 into the second chute 72. Under the action of the torsion spring 65, multiple clamping plates 61 clamp the tail pipe 5. Therefore, this structure can be more convenient to use during the process of placing the intake pipe 4 into the tail pipe 5 without constantly pressing the ring 690. Then, the intake pipe 4 is inserted into the tail pipe 5 and the ring 690 is released. Under the action of the torsion spring 65, the clamping plate 61 rotates towards the side close to the tail pipe 5 until the clamping block 62 clamps the tail pipe 5. At this time, the intake pipe 4 can be stabilized. Therefore, this device realizes the stability of the intake pipe 4 by placing the intake pipe 4 into the tail pipe 5 and using multiple clamping plates 61 to clamp the tail pipe 5, avoiding the phenomenon that the intake pipe 4 detaches from the tail pipe 5, and realizing the integration of gas collection and detection, preventing other gases from being mixed into the tail gas, which is beneficial to improving the detection accuracy and is convenient to use.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
