[0038] Embodiments

[0039] With reference to Figures 1-5 An air suspension height calibration measuring instrument, comprising

[0040] A sliding base 1 is provided with four movable grooves 101 uniformly distributed on the circumference, and the bottom surface of each movable groove 101 is provided with a sliding groove 102;

[0041] A mounting plate 2 is arranged on one side of the sliding base 1 and coaxial with the sliding base 1;

[0042] A scale 3 is fixed at the bottom of the side surface of the mounting plate 2, and the zero scale is located at the center of the mounting plate 2;

[0043] A center cylinder 4 is arranged in the center of the sliding base 1, one end of which is fixedly connected with the mounting plate 2, and the other end is fixedly connected with a limiting block 41;

[0044] A spring 5 is sleeved on the center cylinder 4, one end of which supports the sliding base 1, and the other end supports the limiting block 41;

[0045] Four positioning sliding blocks 6 are arranged in the four movable grooves 101 in a central symmetry, the end of which extends out of the movable groove 101, and the inner side of the positioning sliding block 6 is fixedly connected with a sliding block 8 which is slidably arranged in the corresponding sliding groove 102;

[0046] Four connecting rods 7 correspond to the four positioning sliding blocks 6, one end of the connecting rod 7 is hingedly connected with the positioning sliding block 6, and the other end is hingedly connected with the mounting plate 2.

[0047] With reference to Figure 4When the measuring instrument is not in use, the spring 5 is in a compressed state, providing support for the limit block 41, thereby driving the central cylinder 4 to move to the right, so that the distance between the mounting plate 2 and the slide seat 1 is closer, and the mounting plate 2 supports the positioning slider 6 through the connecting rod 7. The connecting rod 7 tends to a vertical state, causing the positioning slider 6 to move outward, and the sliding block 8 extends from the sliding groove 102. Therefore, under the support of the spring 5, the four positioning sliders 6 are always in an open state.

[0048] Reference Figure 5 、 Figure 6 When the measuring instrument is in use, the mounting plate 2 is moved to the left, thereby driving the center cylinder 4 to move to the left, causing the spring 5 to be further compressed. After the mounting plate 2 moves to the left, the connecting rod 7 tends to be horizontal, causing the positioning slider 6 to move inward, and the sliding block 8 enters the sliding groove 102. At this time, the four positioning sliders 6 are in a retracted state. At this time, the ends of the four positioning sliders 6 can be inserted into the center hole of the wheel 100. After loosening the mounting plate 2, the center cylinder 4 is driven to move to the right under the elastic action of the spring 5, and the four positioning sliders 6 are restored to the open state and support the inner wall of the center hole of the wheel 100 to play a positioning function, thereby fixing the measuring instrument on the wheel 100. The measuring instrument is easy to fix and can be applied to the center holes of wheels of different sizes.

[0049] After the measuring instrument is fixed on the wheel, the distance between the wheel 100 and the vehicle body 200 can be measured by the scale 3. Since the four positioning sliders 6 are symmetrically arranged in the four movable grooves 101, the center of the four positioning sliders 6 is the center of the slide seat 1, and since the mounting plate 2 is coaxial with the slide seat 1, the zero scale of the scale 3 is located at the center of the mounting plate 2. Therefore, no matter whether the four positioning sliders 6 are opened or retracted, the zero scale line of the scale 3 is always at the center of the four positioning sliders 6. When the measuring instrument is fixed on the wheel through the four positioning sliders 6, the zero scale line of the scale 3 is located at the center of the wheel. In this way, when measuring the distance between the wheel 100 and the vehicle body 200, the accuracy of the measurement data can be guaranteed.

[0051] At least two guide columns 9 are provided in the mounting plate 2 and one end of the guide columns 9 is fixedly connected to the slide seat 1 ; the guide columns 9 guide the mounting plate 2 during its movement to ensure that the mounting plate 2 is coaxial with the slide seat 1 .

[0052] In a specific embodiment, the outer side surface of the positioning slider 6 is an arc structure, which can increase the supporting area between the positioning slider 6 and the inner wall of the wheel center hole, ensuring that the measuring instrument is fixed and stable.

[0053] In a specific embodiment, further comprising

[0054] The hinge block 10 is a cross-shaped structure fixed to the side of the mounting plate 2, and the four connecting rods 7 are hinged to the four ends of the hinge block 10 respectively; the mounting plate 2 is hinged to the connecting rod 7 through the hinge block 10, and the connecting rod 7 is easy to install and rotates smoothly.

[0055] In a specific embodiment, further comprising

[0056] The counterweight block 11 is fixed to the lower side of the mounting plate 2, and its center of gravity is on the same vertical line as the center of the mounting plate 2 and the scale 3; through the setting of the counterweight block 11, it is convenient to ensure the vertical state of the scale 3 when the measuring instrument is fixed to the wheel, thereby ensuring the accuracy of the measurement data.

[0057] In a specific embodiment, further comprising

[0058] The level is fixed on the scale 3; the level can display the vertical state of the scale 3 in real time. The scale 3 can be adjusted by the level to make the vertical state of the scale 3 more accurate, thereby further ensuring the accuracy of the measurement data.

[0059] In a specific embodiment, further comprising

[0060] The pressing plate 12 is detachably fixed to the side of the mounting plate 2 and is used to press and fix the scale 3, which facilitates the replacement of the scale 3. Specifically, both ends of the pressing plate 12 are connected to the mounting plate 2 by bolts.
