[0002] Track width and wheelbase are both important parameters in car design. Track width refers to the distance between the center lines of two opposite wheels of a vehicle, usually the distance between the front or rear wheels. Wheelbase refers to the distance between the center lines of the front and rear wheels of a vehicle. To facilitate the adjustment of track width and wheelbase, a manual track width and wheelbase adjustment device is needed.

[0003] A search revealed Chinese Patent Publication No. CN205220853U, which discloses a radar four-wheel adjustment device, including a wheelbase adjustment device and a track width adjustment device, with the wheelbase adjustment device and track width adjustment device fixedly connected. By applying this four-wheel adjustment device to radar equipment, both the track width and wheelbase of the radar equipment can be adjusted, allowing it to travel radially and axially on reinforced concrete structures of any curvature, thus enhancing its practicality. However, in actual use, this device experiences significant wear on the cams during adjustment. Over long-term use, wear causes the cams to shrink, leading to insufficient contact, which may affect adjustment and reduce the device's lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a manual adjustment device for wheel track and wheelbase, which aims to improve the problem that wear of the cam affects the adjustment effect in the prior art.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a manual wheelbase and track adjustment device, including a mounting block 1, a top plate 3 fixedly connected to the top of the mounting block 1, a connecting block 4 provided on the rear side of the mounting block 1, a lifting plate 5 fixedly connected to the front side of the connecting block 4 through the mounting block 1, spring telescopic rods 6 fixedly connected to the bottom left and right sides of the top plate 3, the telescopic ends of the spring telescopic rods 6 fixedly connected to the lifting plate 5, fixing plates 7 provided on the front left and right sides of the connecting block 4, multiple threaded holes 8 are provided around the outer walls of the connecting block 4 and the fixing plates 7, screws 9 are provided inside the threaded holes 8, the fixing plates 7 are threadedly connected to the connecting block 4 by the screws 9, a connecting shaft 10 is slidably connected to the inner side of the mounting block 1, and a fixing mechanism 2 is provided on the outer side of the mounting block 1.

[0030] Specifically, through the fixed connection of connecting block 4 and lifting plate 5, the extension and retraction of spring telescopic rod 6 can move connecting block 4 up and down in mounting block 1. At the same time, the wheelbase can be adjusted by the forward and backward movement of connecting shaft 10 within mounting block 1. Screw 9 is used to fix fixing plate 7 and connect it to threaded holes 8 at different positions. By adjusting the position of fixing plate 7 and the wheel above it, the wheelbase can be changed, allowing the device to easily adjust the wheelbase and wheelbase, while reducing wear on the device. In addition, it also reduces the impact of wear on the adjustment effect.

[0031] Reference Figure 3 The fixing mechanism 2 includes a fixing block 201. The rear top of the mounting block 1 is fixedly connected to the fixing block 201 and rotatably connected to the rear side of the fixing block 201. The front side of the handle 205 passes through the fixing block 201 and is fixedly connected to a threaded rod 202. The outer side of the threaded rod 202 is threadedly connected to a push plate 204. The left and right sides of the rear top of the mounting block 1 are slidably connected to slot blocks 203. The push plate 204 is slidably connected to the slot blocks 203.

[0032] Specifically, by rotating the handle 205, the threaded rod 202 will rotate, thereby pushing the push plate 204 to move back and forth. The movement of the push plate 204 will cause the slot block 203, which is slidably connected to it, to move left and right along the top of the mounting block 1. This design allows us to adjust the position of the slot block 203 to facilitate the installation and disassembly of the device. When it is necessary to install or disassemble the device, the position of the slot block 203 can be adjusted by rotating the handle 205, thereby installing or removing the device. This design is simple and easy to use, and can effectively improve the efficiency of device installation and disassembly.

[0033] Reference Figure 1 and Figure 2 Multiple holes 11 are provided on the bottom left side of the mounting block 1, and a telescopic block 12 is fixedly connected to the left side of the connecting shaft 10; a flange 13 is fixedly connected to the front side of the outer wall of the connecting shaft 10; positioning blocks 15 are fixedly connected to both the left and right sides of the top plate 3, and a third positioning hole 16 is provided on the outer side of each of the two positioning blocks 15.

[0034] Specifically, by extending the telescopic block 12 out of the corresponding hole 11, the position of the connecting shaft 10 inside the mounting block 1 can be fixed. By pressing the telescopic block 12 into the hole 11, the position of the connecting shaft 10 can be moved and adjusted. The flange 13 can be used to fix the connecting shaft 10. By installing a threaded part in the third positioning hole 16 on the positioning block 15, the stability of the device during installation can be improved.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The front left and right sides of the mounting block 1 are provided with sliding grooves 14, and the two lifting plates 5 are slidably connected to the corresponding sliding grooves 14 respectively; the rear top of the mounting block 1 is fixedly connected with a sliding rod 17, and the left and right sides of the fixing plate 7 are slidably connected to the corresponding slot blocks 203 respectively; the front left and right sides of the connecting block 4 are provided with first positioning holes 18, and the front left and right sides of the outer wall of the mounting block 1 are provided with second positioning holes 19.

[0036] Specifically, the stability of the lifting plate 5 during movement can be improved by sliding along the slide bar 17, and the stability of the slot block 203 during movement can be improved by sliding along the slide bar 17. The first positioning hole 18 and the second positioning hole 19 can be fixed by the threaded parts, and the mounting block 1 and the connecting block 4 can be fixed together.

[0037] Working Principle: Before using the device, the mounting block 1 is fixedly connected to the lifting plate 5. The extension and retraction of the spring telescopic rod 6 drives the connecting block 4 to move up and down within the mounting block 1. Simultaneously, the connecting shaft 10 moves back and forth within the mounting block 1, allowing for wheelbase adjustment. By fixing the fixing plate 7 to the threaded holes 8 at different positions using screws 9, the position of the fixing plate 7 and the wheels on it can be adjusted, thus changing the wheelbase. This design facilitates the adjustment of wheelbase and track width, reduces wear on the device during adjustment, and minimizes the impact of wear on the adjustment effect, thereby improving the device's performance. The lifespan of the device is extended, and by turning the handle 205, the threaded rod 202 is driven to rotate, thereby causing the push plate 204 to move back and forth. The movement of the push plate 204 causes the slot block 203, which is slidably connected to it, to move left and right along the top of the mounting block 1. This design allows for adjustment of the position of the slot block 203, facilitating the installation and disassembly of the device. When it is necessary to install or disassemble the device, the position of the slot block 203 is adjusted by turning the handle 205, and the device is placed or removed. This design is simple and easy to use, and can effectively improve the efficiency of installing and disassembling the device, thereby improving the reliability of the device.
