Embodiment 1

[0020] Such as figure 1 with figure 2 As shown, the blower support for automobile testing of the present invention includes a square base 6 on which two side frames 5 are installed. The side frames 5 are triangles enclosed by two side bars and the base 6 , The two side frames 5 are parallel to each other, grooves 4 are provided on the side bars, two arc-shaped plates 1 are installed between the side frames 5, and small rollers are connected at both ends of the arc-shaped plates 1 3. The small roller 3 is placed in the groove 4, a crescent socket 8 is provided on the base 6, and the bottoms of the two arc-shaped plates 1 are slidably arranged in the crescent socket 8 through the roller 10; The balance adjustment structure with the curved plate 1. The base 6 is formed by connecting strips of steel. The base 6 is used as the main body of the fan and has a strong load-bearing capacity. Two parallel side frames 5 are installed on the base 6 and the side frames 5 are composed of tw...

Embodiment 2

[0022] Such as figure 1 As shown, the blower bracket for automobile testing of the present invention, the balance adjustment structure includes a fixed cylinder 9 and a spring 12, the spring 12 is placed in the fixed cylinder 9 and the end of the spring 12 is connected with a slider 13, on the curved plate Two arc-shaped grooves 11 are opened at the bottom of 1, and the slider 13 is slidably arranged in the arc-shaped groove 11. When the fan starts, the sway of the fan body makes the arc-shaped plate 1 move in the crescent groove 8. The two ends of the arc-shaped plate 1 slide freely in the groove 4 under the action of the small rollers 3, and the slider 13 is horizontal. It remains stationary in the direction and is relatively displaced with the arc-shaped slot 11. The arc-shaped plate 1 presses down the slider 13, and the spring 12 is compressed while providing a force in the opposite direction for the slider 13 to maintain the arc-shaped plate. 1. Balance of forces during mo...

Embodiment 3

[0024] Such as figure 1 As shown, the blower bracket used for automobile testing of the present invention has a plurality of pulleys 7 installed on the bottom of the base 6. Furthermore, the bracket is welded with steel as a whole, and the installed pulley 7 not only facilitates the rapid movement of the bracket, but also makes it easier to change the travel route and direction of the fan, which can simulate a moving vehicle more flexibly and facilitate the test row. Wind performance.

[0025] Each side frame 5 is provided with a connecting rod 2, both ends of the connecting rod 2 are respectively connected to the ends of the two arc-shaped plates 1, and the sides of the connecting rod 2 are in contact with the groove wall of the groove 4. Furthermore, as a further improvement of the present invention, connecting rods 2 are installed on the two side frames 5, and one side of the connecting rod 2 is in contact with the groove wall of the groove 4 to limit the fan in the U-shaped c...

Abstract

The invention discloses an air blower support used for automobile testing. The air blower support comprises a square base and two balance adjusting structures, two side frames are mounted on the base and are parallel to each other, a groove is formed in each side strip, two arc-shaped plates are mounted between the side frames, small rollers are connected on the end portions of two ends of the arc-shaped plates, crescent grooves are formed in the base, the bottoms of the arc-shaped plates are slidably arranged in the crescent grooves through rollers, and the balance adjusting structures are arranged between the crescent grooves and the arc-shaped plates. The balance adjusting structures sequentially eliminate undesirable effect generated by vibration of the left end and the right end of an air blower, and sudden stress generated when the air blower is just started can be eliminated when the small rollers slide back and forth in the grooves, so that the arc-shaped plates and the air blower are enabled to maintain balance in the whole process from the time when the air blower starts to work to the time when the same stops working, and an air source capable of stably pushing on the ground is formed; the air blower is adjustable in power and changeable in air speed.

Description

Technical field [0001] The invention relates to an auxiliary tool, in particular to a blower bracket used for automobile testing. Background technique [0002] With the development of the automobile industry and the rapid increase in the number of automobiles, the pollutants emitted by automobiles are unanimously recognized as one of the major air pollution hazards in cities, and have become a serious social problem. Therefore, the detection and control of the concentration of automobile exhaust pollutants, It has become an important inspection item in automobile inspection. The pollutants of automobile exhaust are mainly carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), sulfides (mainly SO2), soot and other harmful substances. Under the same working conditions, gasoline engines emit more CO, HC and NOx emissions than diesel engines. Current emission regulations mainly restrict CO, HC and NOx emissions for gasoline engines. Diesel engines have much lighter air pol...
