The special support device for motor vehicle emission inspection equipment provided by the utility model drives the rotating shaft to rotate by rotating the adjusting disk, and the rotation of the rotating shaft drives the gear to rotate, thereby driving the inner lifting rod to adjust its height through the tooth grooves of the meshing gears, so that the mounting frame drives the inspection equipment to adjust to different height positions, so that personnel can adjust the inspection equipment according to their own heights when using the inspection equipment, thereby effectively improving the practicality of the support device. However, there are still defects that can be improved:

[0004] 1. The utility model has three wheels on the base. Although three wheels are provided on the base, no other fixing devices are provided on the wheels. At the same time, when the supporting device lifts the motor vehicle, the pressure generated by gravity is not completely vertical downward, which means that it is very likely that the entire device will slide when supporting the motor vehicle, bringing danger to people around.

[0005] 2. The utility model lifts the heat sink by meshing the gears and the tooth grooves on the lifting rod. As is known to all, the transmission between the gears and the tooth grooves is not self-locking, that is, after the heat sink is lifted, it is very easy to fall down due to the lack of self-locking and the utility model does not have an additional fixing device, causing the life safety of people around to be not guaranteed.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] The working principle of the utility model is as follows Figure 1-Figure 5 As shown, a supporting device for motor vehicle safety detection equipment includes a base plate 1. First, a supporting plate 11 is arranged in the middle part above the base plate 1. A plurality of anti-slip blocks 12 are fixedly connected to the supporting plate 11. The anti-slip blocks 12 are used for anti-slipping. The front and rear parts of both sides of the bottom end of the supporting plate 11 are fixedly connected with hydraulic telescopic cylinders 10. At the same time, the bottom end of the hydraulic telescopic cylinder 10 is fixedly connected to the base plate 1. Then, a lifting device 9 is arranged in the middle part of the top end of the base plate 1. In addition, a rotating seat 4 is fixedly connected to the front part of the top end of the base plate 1. A groove 5 is opened at the top end of the rotating seat 4. A trolley handle 6 is arranged in the groove 5. The trolley handle 6 can rotate around the rotating seat 4 at a certain angle. Then, a lifting device 9 is arranged at the top end of the base plate 1. It is hinged with a spring 7. It is worth noting that the spring 7 is located in front of the rotating seat 4, and the top of the spring 7 is hinged to the bottom of the cart handle 6. At the same time, a damper 8 is arranged inside the spring 7. The top and bottom ends of the damper 8 are respectively hinged to the cart handle 6 and the base plate 1. The solution formed so far is that the user can rotate the cart handle 6 to a suitable angle to pull the device. When the pulling stops, the spring 7 can restore the cart handle 6 to its original position. In addition, support columns 13 are fixedly connected to the front and rear parts of both sides of the bottom end of the base plate 1, and then wheels 2 are arranged at the front and rear parts of both sides below the support columns 13. Finally, the wheels 2 and the support columns 13 are connected to each other by a fixing device 3.

[0032] The above-mentioned structures together constitute the general appearance structure of a supporting device for motor vehicle safety detection equipment of the utility model.

[0033] In order to further explain the specific working principle of the support device of a motor vehicle safety detection equipment of the utility model, the lifting device 9 includes a motor 901 located in the middle of one side of the top of the base plate 1. First, threaded blocks 908 are fixedly connected to both sides of the bottom end of the support plate 11. At the same time, the bottom end of the threaded block 908 is threadedly connected to a screw rod 907. The bottom ends of the screw rods 907 on both sides are fixedly connected to worm gears 905. The bottom end of the worm gear 905 is fixedly connected to a rotating shaft 906. The bottom ends of the rotating shafts 906 on both sides are rotatably connected to the bottom. On the seat plate 1, at the same time, a worm 903 is meshed at the front end of the worm wheel 905. It is worth noting here that when the worm 903 rotates, the two worm wheels 905 meshed with the worm 903 will rotate at the same time, and then a baffle 904 is rotated and connected at one end of the worm 903, and at the same time, the bottom end of the baffle 904 is fixedly connected to the base plate 1, and in addition, the end of the worm 903 away from the baffle 904 is fixedly connected to the motor 901, and finally the motor 901 is fixedly connected to the top of the base plate 1 by providing a motor seat 902.

[0034] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the motor 901 rotates, it will first drive the worm 903 to start rotating, and then the rotation of the worm 903 will drive the two worm wheels 905 meshing with the worm 903 to start rotating. When the worm wheel 905 rotates, it will simultaneously drive the rotating shaft 906 fixedly connected to the bottom end of the worm wheel 905 to rotate on the base plate 1, and the screw rod 907 fixedly connected to the top end of the worm wheel 905 to rotate. Since the screw rods 907 on both sides are threadedly connected to the corresponding threaded blocks 908, and the top end of the threaded block 908 is fixedly connected to the support plate 11, when the screw rod 907 rotates, the corresponding threaded block 908 moves up and down in the vertical direction, thereby driving the support plate 11 to move up and down.

[0035] In order to further explain the specific working principle of the support device of a motor vehicle safety detection equipment of the utility model, the above-mentioned fixing device 3 includes a receiving seat 301 fixedly connected to the bottom end of the support column 13. First, the rear part of the bottom end of the receiving seat 301 is fixedly connected to the wheel frame 302, and the wheel frame 302 is used in conjunction with the wheel 2. Then, a positioning block 309 is arranged in front of the wheel 2. The positioning block 309 is used to fix the wheel 2 and prevent the wheel 2 from rotating. At the same time, it is worth noting that a plurality of friction blocks are arranged on the side of the positioning block 309 close to the wheel 2 to ensure that there is a large friction and resistance on the positioning block 309 so that the wheel 2 will not rotate. Then, a connecting plate 308 is fixedly connected to the front end of the positioning block 309. The top of the connecting plate 308 is fixedly connected to the sliding plate 307, the middle of the sliding plate 307 is inserted with a guide rod 304, the front end of the guide rod 304 is fixedly connected to the fixed plate 303, the top of the fixed plate 303 is fixedly connected to the bottom end of the receiving seat 301, and at the same time, a positioning plate 305 is fixedly connected to the rear end of the guide rod 304, the positioning plate 305 is used to prevent the sliding plate 307 from sliding out of the guide rod 304, the top of the positioning plate 305 is fixedly connected to the bottom end of the receiving seat 301, and finally a power part is arranged on the fixed plate 303, that is, a hydraulic telescopic cylinder 2 306 is fixedly connected to the middle of the rear end of the fixed plate 303, and the rear end of the hydraulic telescopic cylinder 2 306 is fixedly connected to the front end bottom of the sliding plate 307.

[0036] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when it is necessary to fix the wheel 2 to prevent it from rotating, first the working rod of the hydraulic telescopic cylinder 306 is extended to the rear end, pushing the sliding plate 307 to slide backward on the guide rod 304, and then the connecting plate 308 fixedly connected to the sliding plate 307 is displaced backward while the sliding plate 307 slides backward, and at the same time, it will also push the positioning block 309 to slide backward together. When the positioning block 309 is pushed to the appropriate position, the hydraulic telescopic cylinder 306 will stop running. Since the hydraulic telescopic cylinder 306 has a certain self-locking property, the positioning block 309 can be kept to continuously block the rotation of the wheel 2.

[0037] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.

[0038] In addition, the electrical components appearing in this article are all connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. At the same time, the hydraulic telescopic cylinder mentioned in this article is connected to the external oil circuit. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. In order to ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.
