[0027] The embodiment of the utility model provides a motor vehicle inspection equipment roller that is easy to adjust.

[0028] See also Figure 1 、 Figure 2 and Figure 3 , including a detection shell 1, the top surface of the detection shell 1 is fixedly connected with a protective plate 14, the protective plate 14 can block the gap inside the detection shell 1, to prevent the gap between the detection roller 4 and the detection shell 1 from being too large and affecting the entry of the motor vehicle, and at the same time, it can also prevent debris from falling into the gap and affecting the use of the detection roller 4.

[0029] See also Figure 3 The interior of the detection shell 1 is slidably connected to the lifting support seat 2, and both ends of the lifting support seat 2 are fixedly connected to the stabilizing column 10. A stabilizing groove 11 is opened inside the detection shell 1, and the stabilizing column 10 is adapted to the stabilizing groove 11. Through the setting of the stabilizing column 10 and the stabilizing groove 11, the sliding of the lifting support seat 2 can be limited, so that the lifting support seat 2 remains stable during the lifting process, preventing the lifting support seat 2 from tilting and affecting the normal detection operation of the detection roller 4.

[0030] See also Figure 1 and Figure 3 Two detection rollers 4 are rotatably installed inside the lifting support seat 2, and two servo motors 5 are fixedly installed inside the lifting support seat 2. The two detection rollers 4 are respectively fixedly connected to the output shafts of the two servo motors 5. The servo motors 5 are prior art and will not be described in detail in this application. When the servo motors 5 are started, they can drive the detection rollers 4 to rotate, thereby detecting the wheels of the motor vehicle. The outer surface of the detection roller 4, the detection shell 1 and the top surface of the protective plate 14 are all friction-treated, which can increase the friction between the motor vehicle and the detection equipment and prevent the motor vehicle from slipping during the detection process.

[0031] See also Figure 2 and Figure 3 The inner bottom wall of the detection shell 1 is fixedly connected with a fixing seat 6, which is slidably connected to the lifting support seat 2. The top surface of the fixing seat 6 is also friction-treated. When the motor vehicle wheel is detected between the two detection rollers 4, the fixing seat 6 provides a certain support for the wheel. When the lifting support seat 2 is raised and lowered inside the detection shell 1, the relative height of the detection roller 4 and the third roller 7 can be changed, so that the device can detect wheels with different diameters.

[0032] Please refer again Figure 1 and Figure 3A third roller 7 is provided above the fixed seat 6. Both ends of the third roller 7 are fixedly connected to an elastic rod 8. Each elastic rod 8 is fixedly connected to the fixed seat 6. The third roller 7 is used to control the slip rate of the vehicle during detection. The elastic rod 8 has a certain elasticity. When the motor vehicle is detected, the third roller 7 will be squeezed to cause the elastic rod 8 to bend to a certain extent. When the motor vehicle detection is completed, the elastic rod 8 will return to its original shape to facilitate the third roller 7 to perform another detection operation.

[0033] A data transmitter 9 is fixedly mounted on the outer surface of the lifting support seat 2. The third roller 7 and the data transmitter 9 are electrically connected via a data line. The third roller 7 and the data transmitter 9 are both prior art and will not be described in detail in this application. The third roller 7 can transmit a pressure signal to the PC via the data transmitter 9, which facilitates the computer to control the detection process. At the same time, it can also reduce the friction force on the detection wheel and protect the service life of the wheel.

[0034] The top surface of the detection shell 1 is fixedly connected to a protection box 12, and the interior of the detection shell 1 is fixedly connected to a connecting rod 13. The interior of the protection box 12 is installed with an engine tachometer and other components used for detection. The protection box 12 can protect the components inside it to prevent the motor vehicle from damaging the detection equipment during the detection process. The connecting rod 13 can improve the connection stability of the detection shell 1 and provide safety for the detection work of the equipment. The engine tachometer and other components used for detection are all existing technologies and will not be described in detail in this application.

[0035] See also Figure 2 、 Figure 3 and Figure 4 Two sets of adjustment mechanisms 3 for adjusting the height are provided inside the detection shell 1. The adjustment mechanism 3 includes a hollow groove 301 opened on the inner wall of the detection shell 1. The two sides of the hollow groove 301 have a certain curvature, which is adapted to the lifting arm of the lifting connecting seat 303, and can provide space and stable support for the lifting operation of the lifting arm 304.

[0036] A lift 302 is fixedly installed inside the empty slot 301, and a lift connecting seat 303 is fixedly connected to the outer surface of the lift 302. The lift 302 is a prior art and will not be described in detail in this application. The lift 302 has a very strong lifting force and can drive the lift connecting seat 303 to rise and fall inside the empty slot 301, thereby providing power for adjusting the height of the detection roller 4 of the equipment.

[0037] The outer surface of the lifting connecting seat 303 is fixedly connected to the lifting arm 304, and the two ends of the lifting arm 304 are fixedly connected to the connecting end 305. The connecting end 305 is fixedly connected to the lifting support seat 2. The lifting and lowering of the lifting connecting seat 303 can drive the lifting arm 304 to move up and down. When the lifting arm 304 is lifted and lowered, it can lift the lifting support seat 2 to slide up and down inside the detection shell 1, thereby making a small adjustment to the height of the detection roller 4 inside the lifting support seat 2, so that the device can be suitable for wheels of various diameters, thereby improving the applicability of the device.

[0038] See also Figure 4 The outer surface of the lifting arm 304 is fixedly connected with a cross slider 306, and the inner wall of the empty slot 301 is provided with a limiting slide groove 307. The cross slider 306 is slidably connected to the limiting slide groove 307. Through the setting of the cross slider 306 and the limiting slide groove 307, support and limitation can be provided for the lifting and lowering of the lifting arm 304, so that the lifting arm 304 remains stable when lifting the lifting support seat 2, avoiding the lifting arm 304 from sinking and affecting the stability of the equipment detection operation.

[0039] Working principle: When the staff wants to adjust the height of the detection roller 4, first start the lift 302 according to the actual wheel diameter of the vehicle being detected. The lift 302 starts to drive the lifting connecting seat 303 to rise and fall, and the lifting connecting seat 303 rises and falls to drive the lifting arm 304 to rise and fall. The lifting arm 304 rises and falls to drive the lifting support seat 2 to slide inside the detection shell 1, thereby changing the relative height of the detection roller 4 inside the lifting support seat 2, so that the detection roller 4 can be adjusted in height according to actual needs. Then drive the motor vehicle into the detection equipment, and then start the servo motor 5 to start detecting the motor vehicle, so that the device can adjust the height of the detection roller 4 according to different motor vehicles, thereby improving the detection accuracy of the detection equipment.
