Detailed Description of the Preferred Embodiment

[0023] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. However, the embodiments of the present utility model are not limited thereto.

[0024] As Figure 1-Figure 4 shown, this embodiment provides a locking hole inspection tool, including a U-shaped plate 1. Positioning holes 2 are symmetrically opened at the upper and lower ends of the U-shaped plate 1. A bolt 3 is vertically slidably arranged inside the positioning hole 2 at the top end of the U-shaped plate 1. A limiting block 4 is fixed to the top end of the bolt 3. A return spring 5 is arranged between the bottom end of the limiting block 4 and the top of the U-shaped plate 1. The bolt 3 passes through the inside of the return spring 5. Limiting mechanisms 6 are arranged at the front and rear ends inside the U-shaped plate 1, and a depth adjusting mechanism 7 is arranged on the inner side of the U-shaped plate 1.

[0025] Overall working principle: The distance between the upper and lower ends inside the U-shaped plate 1 is greater than the depth of the locking hole. Before use, according to the wall thickness outside the locking hole, the depth adjusting mechanism 7 is adjusted to limit the distance inserted into the inside of the U-shaped plate 1 at the position of the locking hole. During use, hold the U-shaped plate 1 by hand and place it at the position of the locking hole on the steering knuckle. During the insertion process, the two limiting mechanisms 6 at the position of the locking hole are pushed outwards and positioned outside the locking hole. In addition, the insertion depth of the locking hole has been limited. Therefore, after the U-shaped plate 1 is inserted, the positioning holes 2 are located at the upper and lower ends of the locking hole. Then, press down the bolt 3 to pass it through the inside of the locking hole for inspection, and after the inspection, use the return spring 5 to reset the bolt 3, which is more convenient to use.

[0026] In this embodiment, buckling grooves 8 are vertically opened on the front and rear end faces of the U-shaped plate 1.

[0027] Local working principle: When holding the C-shaped plate 1 by hand, the fingers are buckled inside the buckle groove 8, making the handhold more stable.

[0028] In this embodiment, the limiting mechanism 6 includes a guide groove 9, a slider 10, a compression spring 11 and a roller 12. The guide grooves 9 are symmetrically formed at the inner top and inner bottom of the C-shaped plate 1, and the guide grooves 9 are respectively located on both sides of the positioning hole 2. Sliders 10 are slidably arranged at one ends of the guide grooves 9 close to the positioning hole 2. Compression springs 11 are installed between the sides of the sliders 10 away from the positioning hole 2 and the ends of the guide grooves 9. Rollers 12 are rotatably installed between the two groups of sliders 10 at the inner top and inner bottom of the C-shaped plate 1.

[0029] Local working principle: When inserting the C-shaped plate 1 into the position of the locking hole, the two rollers 12 are extruded outward at the locking hole, controlling the slider 10 to slide inside the guide groove 9. After the C-shaped plate 1 is inserted, the compression spring 11 extrudes the roller 12 to make it closely attached to the outside of the locking hole on the steering knuckle, positioning the position of the C-shaped plate 1.

[0030] In this embodiment, the roller 12 is cylindrical in shape, and a wear-resistant coating is applied to the outside of the roller 12.

[0031] Local working principle: During use, friction will occur between the steering knuckle and the roller 12. The use of the wear-resistant coating can reduce the wear of the roller 12.

[0032] In this embodiment, the depth adjustment mechanism 7 includes a sliding sleeve 13, a screw 14 and a stopper 15. The sliding sleeve 13 is horizontally slidably installed on the inner side of the C-shaped plate 1. A stopper 15 is fixed to one end of the sliding sleeve 13 inside the C-shaped plate 1. A screw 14 is rotatably installed on the side of the C-shaped plate 1, and the screw 14 is threadedly connected to the sliding sleeve 13.

[0033] Local working principle: Since the wall thickness of the locking hole is different, in order to ensure the alignment of the positioning hole 2 and the locking hole during insertion, the insertion depth of the locking hole into the C-shaped plate 1 is different. Therefore, before use, rotate the screw 14 to control the translation of the stopper 15 at the end of the sliding sleeve 13 to limit the insertion depth of the locking hole.

[0034] In this embodiment, a groove 16 is formed on the inner side of the C-shaped plate 1, and the stopper 15 is hidden inside the groove 16.

[0035] Local working principle: The use of the groove 16 can conveniently hide the stopper 15 in the initial state.

[0036] In this embodiment, the end of the screw 14 away from the sliding sleeve 13 is on the same vertical plane as the side of the C-shaped plate 1, and a linear groove 17 is formed at the end of the screw 14.

[0037] Partial working principle: When the control screw 14 rotates, a flat-blade screwdriver is inserted into the linear groove 17 for adjustment, which is easy to operate.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
