Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1-5 As shown, this embodiment of a contact wire geometric parameter measuring instrument includes a measuring instrument body and a track ruler 1. The track ruler 1 is provided with a ruler body holder 3 and a locking mechanism 4. The locking mechanism 4 is located below the ruler body holder 3. The locking mechanism 4 includes a guide rod 41, a locking block 42, a traction mechanism 43, and a telescopic spring 44. The locking block 42 is slidably connected to the guide rod 41. The traction mechanism 43 is connected to the locking block 42. The telescopic spring 44 is sleeved on the outside of the guide rod 41. The ruler body holder 3 is fixedly connected to the track ruler 1. The ruler body holder 3 is provided with a first through hole. The measuring instrument body is provided with a main unit base 5. A locking hook 51 that cooperates with the locking block 42 is provided below the main unit base 5.

[0024] The working principle of this utility model is as follows: the traction mechanism 43 pulls the locking block 42 towards the telescopic spring 44, compressing the telescopic spring 44; the main unit base 5 of the measuring instrument is placed on the scale body bracket 3 of the track ruler 1, and the locking hook 51 below the main unit base 5 passes through the first through hole of the scale body bracket 3; the traction mechanism 43 is released, and under the action of the elastic force of the telescopic spring 44, the locking block 42 engages with the locking hook 51, thereby locking and fixing the measuring instrument main unit. This utility model achieves the fixing of the measuring instrument main unit through the cooperation of the locking block 42 of the locking mechanism 4 and the locking hook 51 of the main unit base 5. The locking method of this utility model helps to improve the stability of the connection between the measuring instrument main unit and the track ruler 1, ensuring the accuracy of the measurement results.

[0025] The end of the locking block 42 is a wedge structure, and the end of the locking hook 51 is a wedge structure, which are matched to facilitate the locking block 42 to be clamped into the locking hook 51, and improve the locking effect of the locking block 42 on the locking hook 51.

[0026] The end of the locking block 42 is provided with a limiting column 45, and the locking hook 51 is provided with a second through hole 52 matched with the limiting column 45, so that after the locking block 42 is clamped into the locking hook 51, the limiting column 45 is inserted into the second through hole 52, the separation of the main body of the measuring instrument and the ruler body clamping seat 3 caused by artificial hard pulling is prevented, and the stability and firmness of the locking mechanism 4 on the main machine base 5 and the main body of the measuring instrument are further improved.

[0027] The traction mechanism 43 is a steel wire rope or a traction rod, and the end of the traction mechanism 43 is provided with a locking handle 46, which facilitates the locking block 42 to move away from the first through hole, and facilitates the locking block 42 to move to the locking hook 51 under the elastic force of the telescopic spring 44.

[0028] The length of the first through hole is consistent with the length of the locking hook 51, after the locking hook 51 is inserted into the first through hole, the two ends of the locking hook 51 are in contact with the inner walls of the two ends of the first through hole, so that the movement of the locking hook 51 in the direction perpendicular to the length direction of the track ruler 1 is limited, and the fixing effect of the locking mechanism 4 on the main machine of the measuring instrument is improved.

[0029] The upper surface of the ruler body clamping seat 3 is provided with a first recess, the lower surface of the main machine base 5 is provided with a second recess, the first recess is matched with the second recess, the length direction of the first recess is perpendicular to the length direction of the second recess, which is beneficial to the precision of the cooperation between the first recess and the second recess, so as to ensure the accuracy of the measurement after the main machine of the measuring instrument and the track ruler 1 are fixed.

[0030] One end of the track ruler 1 is provided with a fixed end measuring seat 6 and a fixed end measuring head 7, and the other end is provided with a movable end measuring seat 8 and a movable end measuring head 9, the movable end measuring seat 8 is movably connected with the track ruler 1, which is convenient for measuring the track spacing, or for fixing the track ruler 1 above the track.

[0031] The track ruler 1 is provided with a track spacing adjusting handle 10, the movable end measuring seat and the track ruler 1 can be pulled to slide through the track spacing adjusting handle 10, and the movable end measuring head is tightly pressed against the inner side of the track under the action of the elastic mechanism in the movable end measuring seat.

[0032] It should be explained finally that the above embodiment is only used to illustrate the technical scheme of the utility model, and is not the limit of the protection scope of the utility model, although the utility model is explained in detail with reference to the preferred embodiment, the ordinary skilled in the art should understand that the technical scheme of the utility model can be modified or replaced equivalently, and does not deviate from the essence and scope of the technical scheme of the utility model.
