Description

Technical Field

[0001] This utility model relates to the field of wheel adjustment, and more specifically, to an adjuster for adjusting wheel spacing. Background Technology

[0002] When installing and positioning the wheels, it is necessary to combine and install an adjusting device to indirectly combine the axle and the wheel, and fix it with bolts. It is a tool that increases the distance between the two wheel hubs.

[0003] The utility model patent with authorization announcement number CN 222277307 U relates to the field of transition disc technology and discloses an anti-loosening wheel adjuster transition disc, comprising: a fixed disc, a gasket embedded in the top of the fixed disc, a chuck assembled on the outside of the fixed disc, a limiting mechanism rotatably connected inside the fixed disc, the limiting mechanism including a rotating disc, a lever fixedly connected to the outside of the rotating disc, a crank arm connected to the inside of the rotating disc via a hinge, and a latch rotatably connected to the other end of the crank arm via a first pin arm, a second pin arm inserted into the top of the latch arm and fixedly connected to the fixed disc, and springs fixedly connected to both ends of the bottom of the latch arm. This anti-loosening wheel adjuster transition disc, through the added latch arm and chuck, automatically locks the position of the limiting mechanism when it is fixed, preventing the limiting mechanism from shaking back after fixing, thus avoiding failure of the fixed disc's fixation.

[0004] The above-disclosed structure uses a double-layer structure for transition connection, but it lacks a separate connecting cylinder to install the annular gasket. It is impossible to adjust the installation thickness after separate connection, which makes it inconvenient to adjust the wheel spacing, resulting in poor adaptability. Furthermore, it is impossible to add a fixing position after alignment installation, which needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an adjuster for adjusting wheel spacing. It connects an inner connecting cylinder to a first fixing plate, and installs a second fixing plate in conjunction with an outer connecting cylinder, thereby fitting and installing an annular washer. It can be assembled and positioned separately to adjust the installation thickness and change the spacing, making it highly adaptable. Furthermore, it uses a combination screw installed in the inner central cylinder to lock and fix it after alignment, ensuring safety and stability, facilitating adjustment and use, and making it highly adaptable.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An adjuster for adjusting wheel spacing includes a first fixing plate with a first fixing hole on its surface. An inner connecting cylinder is fixedly connected to one side surface of the first fixing plate. An annular washer is slidably sleeved on one end of the outer surface of the inner connecting cylinder. An outer connecting cylinder is slidably sleeved on the outer surface of the inner connecting cylinder. A second fixing plate is fixedly connected to one end of the outer connecting cylinder. The second fixing plate has a second fixing hole on its surface. A central cylinder is fixedly connected to the middle position inside the inner connecting cylinder. The central cylinder has a threaded hole inside. A countersunk hole is provided on one side of the second fixing plate. A through hole is provided inside the countersunk hole. A combination screw is rotatably installed inside the through hole. The combination screw is threaded into the threaded hole.

[0008] Furthermore, the outer connecting cylinder has a spline groove inside, which is fitted onto the surface of the inner connecting cylinder.

[0009] Furthermore, a spline head is fixedly connected to the outer surface of the inner connecting cylinder, and the spline head is inserted into the inside of the spline groove.

[0010] Furthermore, the spline head and spline groove are one-to-one and are combined and connected inside the outer connecting cylinder. The spline groove is set through the outer connecting cylinder, and the spline head is connected to the inner connecting cylinder. It can be plugged in and positioned, and the spacing can be adjusted axially while avoiding radial slippage. This facilitates combined adjustment and use, and is safe and stable.

[0011] Furthermore, the central cylinder is fixedly connected to the inner side of the first fixed plate and is located at the center of the inner connecting cylinder.

[0012] Furthermore, the first fixing plate and the second fixing plate have the same diameter and are located at the two ends of the inner connecting cylinder and the outer connecting cylinder, respectively.

[0013] Furthermore, the annular washers are stacked in layers and connected to the outside of the inner connecting cylinder. The outer connecting cylinder is pressed and connected to the surface of the annular washers. By combining the first fixing plate and the second fixing plate, and combining the stacked annular washers, the installation thickness can be adjusted and pressed and fixed, which is conducive to adjusting the distance on both sides and convenient for positioning and use.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution connects the internal connecting cylinder with the first fixing plate and installs the second fixing plate with the external connecting cylinder, thereby fitting and installing the annular washer. It can be assembled and positioned separately, thereby adjusting the installation thickness and changing the spacing. It has high adaptability. Furthermore, the internal central cylinder is used to install the combination screw, which can be locked and fixed after alignment, ensuring safety and stability. It is easy to adjust and use, and has high adaptability.

[0016] (2) A spline groove is set by an external connecting cylinder and a spline head is connected by an internal connecting cylinder. It can be plugged in for positioning and can slide to adjust the spacing axially. At the same time, it avoids slipping in the radial direction, which is conducive to combination adjustment and safe and stable.

[0017] (3) By combining the first fixing plate and the second fixing plate, and combining the stacked annular washers, the installation thickness can be adjusted to press and fix, which is conducive to adjusting the distance on both sides and convenient for positioning and use.
