Description

Technical Field

[0001] The utility model relates to the technical field of tire size detection, in particular to a tire size detection device which is convenient for rotation adjustment. Background Art

[0002] As an important automobile component, tires need to be strictly inspected after production. The production quality of tires can be controlled through the test data to ensure that the tires that are finally shipped and used meet the usage standards. After the rubber tires are produced and processed, they need to be tested for size to ensure that the produced rubber tires meet the requirements.

[0003] The patent with publication number CN112254608B discloses a rubber tire size detection mechanism, including a detection component and a fixing component. A limiting groove is provided on the upper end of a support plate to cooperate with a support tube and a ball to set a chassis. The detector is suspended on the upper end of the chassis by using an installation vertical plate to cooperate with a horizontal tube and a moving rod. The connecting block is fixedly connected to the outer wall of the end of the moving rod. A threaded tube is provided through the inner wall of the connecting block. The threaded tube cooperates with a screw to movably connect the cross bar at the bottom of the connecting block. The outer walls on both sides of the cross bar are respectively movably sleeved with sleeves of arc blocks at the ends. The sleeves are movably connected to the outer walls on both sides of the threaded tube by using connecting clips to cooperate with connecting strips. The steering wheel at the top of the rotating screw controls its upward movement, reduces the distance between the cross bar and the threaded tube, and makes the sleeve slide on the outer wall of the cross bar to push the arc block to fit the inner wall of the tire. When the arc block is not in the center line position of the tire, the arc block pushes the tire and the chassis to move in the limiting groove, ensuring that the cross bar moves to the center line of the tire, providing accurate marking lines for the inner and outer diameter detection of the tire.

[0004] During use, the above-mentioned device for detecting tire size can synchronously measure the inner and outer diameters of the tire, but it requires repeated operations to twist the loosening bolts and the screw rods for many times, which is cumbersome and inconvenient to use. In addition, the detection of tire size generally also includes the detection of its thickness, but the above-mentioned structure lacks a corresponding structure. If the tire thickness is to be measured, a separate equipment structure is required for detection, which is inconvenient to use and relatively poor in practicality. Utility Model Content

In this example, the detection mechanism also includes a measuring rod 10, and the lower end of the measuring rod 10 passes through the slider 8 and the fixed plate 9, and a plurality of scale values ​​are arranged on one side of the measuring rod 10 and the side of the adjustment frame 5, and the scale values ​​arranged on the side of the adjustment frame 5 are symmetrical, and a fixed block 11 is symmetrically arranged on one side of the top of the fixed plate 9, and a torsion bar 12 is rotatably installed between the fixed blocks 11, and one end of the torsion bar 12 passes through the fixed block 11 and is connected to a torsion handle, and a gear 13 is sleeved on the outer wall of the torsion bar 12, and a rack 15 is meshed and connected to the lower part of the gear 13, and one end of the rack 15 is A plug post 16 is connected, and the plug post 16 is moved and inserted into a socket opened on one side of the measuring rod 10, and there are several sockets. A torsion spring 14 is symmetrically sleeved on the outside of the torsion bar 12, and the torsion spring 14 is located on both sides of the gear 13. The two ends of the torsion spring 14 are respectively fixedly connected to the torsion bar 12 and the fixed block 11. Through the detection mechanism, the two measuring rods 10 can be conveniently and synchronously adjusted to move synchronously to the relative inside or outside, so as to detect the inner diameter or outer diameter of the tire, and the thickness of the tire can also be detected. It is easy to use and more practical. In this example, the clamping assembly includes a telescopic rod 18, and the telescopic rod 18 is embedded and installed at the bottom of the base 1. The telescopic end of the telescopic rod 18 is movably connected to a plurality of connecting rods 19, and one end of the connecting rod 19 is movably connected to a clamping plate 20.

The device is convenient for synchronously adjusting the movement of the two measuring rods 10, thereby detecting the inner and outer diameters of the tire, and detecting the thickness of the tire while detecting the tire diameter, which is convenient to use and more practical.
