During use, the height of each support leg is adjusted individually, and a level is used to ensure the measurement reference plane is horizontal, guaranteeing measurement accuracy. However, when particles or dust adhere to the bottom of the support legs, the length measuring instrument needs to be flipped over to clean the bottom of the legs. Flipping the length measuring instrument increases the workload for operators. Therefore, this solution proposes a length measuring instrument for bearings to address the aforementioned problems.

[0024] 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.

[0025] This utility model provides, for example Figure 1-4 The length measuring instrument shown includes:

[0026] Length measuring instrument body 1;

[0027] Support pad 2, multiple support pads 2 are respectively set at the four corners of the bottom of the length measuring instrument body 1;

[0028] Fixing base 3, multiple fixing bases 3 are symmetrically fixedly connected to both sides of the length measuring instrument body 1;

[0029] The flip seat 4 is located on top of the support pad 2. An adjustment component 5 for adjusting the position of the support pad 2 is provided at the connection between the flip seat 4 and the support pad 2. A rotating component 6 for rotating the flip seat 4 is provided at the connection between the fixed seat 3 and the flip seat 4. A limiting component 7 for limiting the rotation of the rotating component 6 is provided on the top of the rotating component 6.

[0030] It should be noted that the working principle of the length measuring instrument body 1 is the same as that of the JD18 length measuring instrument; four support pads 2 are set, which are respectively set at the four corners of the bottom of the length measuring instrument body 1, and the length measuring instrument body 1 is supported by the support pads 2; when it is necessary to clean the bottom of the support pads 2, one of the support pads 2 is moved upward by adjusting component 5, then the support pad 2 is rotated by rotating component 6, and finally the bottom of the support pad 2 is cleaned by cleaning tool, so as to avoid the need to flip the entire length measuring instrument body 1 during cleaning.

[0031] Specifically, the adjustment component 5 includes an extension block 504 fixedly connected to the top of the support pad 2. The top of the extension block 504 is provided with a threaded groove 506. A threaded post 505 is threadedly connected inside the threaded groove 506. A cavity 401 is provided in the middle of the flip seat 4. The threaded post 505 is threadedly connected to the inner wall at the top of the cavity 401. A fixed bearing 502 is provided at the connection between the threaded post 505 and the flip seat 4. A torsion cap 501 is fixedly connected to the top of the threaded post 505. A limiting groove 402 is provided on the inner wall of one side of the cavity 401. A first limiting block 503 is fixedly connected to one side of the extension block 504. The first limiting block 503 is threadedly connected inside the limiting groove 402.

[0032] It should be noted that the fixed bearing 502 is an existing ball bearing. The fixed bearing 502 connects the threaded column 505 and the flip seat 4, thereby fixing the position of the threaded column 505 without affecting its rotation. The horizontal cross-section of the limiting groove 402 and the first limiting block 503 is set as an equilateral triangle. This design limits the movement direction of the first limiting block 503, and the first limiting block 503 limits the movement direction of the extension block 504. The threaded groove 506 is adapted to the threaded column 505, so that the threaded column 505 can be connected to the extension block 504 through the threaded groove 506. When the position of the support pad 2 needs to be moved, the twist cap 501 drives the threaded column 505 to rotate, and the rotating threaded column 505 drives the extension block 504, which is threaded to it but cannot rotate, to move, and the moving extension block 504 drives the support pad 2 to move.

[0033] Specifically, the rotating assembly 6 includes a positioning shaft 602 fixedly connected to one side of the fixed base 3, the positioning shaft 602 being inserted through and connected to one side of the flip base 4, and a blocking disk 601 fixedly connected to one end of the positioning shaft 602.

[0034] It should be noted that a hole adapted to the positioning shaft 602 is provided on one side of the flip base 4, and the hole is interconnected with the cavity 401, so that the positioning shaft 602 can be connected to the blocking plate 601 located inside the cavity 401 through the hole. The diameter of the blocking plate 601 is larger than the diameter of the hole, so that the flip base 4 cannot move away from the fixed base 3, and the flip base 4 rotates around the positioning shaft 602 as the center.

[0035] Specifically, the limiting component 7 includes a positioning groove 701 formed on one side of the blocking plate 601, a positioning block 702 is inserted inside the positioning groove 701, a sliding block 703 is fixedly connected to one side of the positioning block 702, a spring 705 is provided on the top of the sliding block 703, and a second limiting block 704 is fixedly connected to one side of the sliding block 703. The second limiting block 704 is inserted inside the limiting groove 402.

[0036] It should be noted that the limiting groove 402 is adapted to the second limiting block 704, and both have an isosceles trapezoidal cross-section. This design restricts the movement direction of the second limiting block 704 and the sliding block 703. The cross-section of the sliding block 703 is annular, allowing the threaded post 505 to pass through the sliding block 703. A spring 705 is provided on the top of the sliding block 703, which pushes the sliding block 703 toward one side of the extension block 504.

[0037] Furthermore, when it is necessary to restrict the rotation of the flip seat 4, the spring 705 drives the sliding block 703 and the positioning block 702 to move downwards, and the positioning block 702 is inserted into the positioning groove 701. The fixed-position blocking plate 601 restricts the rotation of the positioning block 702 and the sliding block 703, and the sliding block 703 restricts the position of the flip seat 4, so that the flip seat 4 cannot rotate. When it is necessary to rotate the flip seat 4, the threaded column 505 drives the extension block 504 to move upwards, and the extension block 504 drives the sliding block 703 to move upwards, so that the sliding block 703 drives the positioning block 702 to move out of the positioning groove 701, thereby removing the restriction on the flip seat 4, allowing the flip seat 4 to rotate.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
