Detailed Implementation

[0025] like Figures 1 to 5 As shown, this utility model discloses a laser diameter measuring instrument, including a base 1, a laser emitting device 2, and a laser receiving device 3. Both the laser emitting device 2 and the laser receiving device 3 are mounted on the base 1. The base 1 is equipped with a guide assembly 4, which is positioned between the laser emitting device 2 and the laser receiving device 3. The guide assembly 4 includes a fixed frame 5, guide wheels 6, and pressure wheels 7. Guide wheels 6 and pressure wheels 7 are both mounted on the fixed frame 5 and rotatably connected to it. The guide wheels 6 and pressure wheels 7 are in contact with each other. This configuration allows for the fixing and tensioning of the cable to be measured, enabling continuous cable movement for measurement, improving measurement accuracy and effect, and facilitating continuous measurement. In use, the cable to be measured is sequentially passed through the guide assemblies 4 on both sides of the base 1, and the cable is positioned between the guide wheels 6 and pressure wheels and tensioned. Then, by pulling one side of the cable, continuous cable measurement is achieved.

[0026] In one implementation, the mounting bracket 5 includes a support rod 8 and a movable rod 9. A guide wheel 6 is mounted on the support rod 8, and a pressure wheel 7 is mounted on the movable rod 9. One end of the movable rod 9 is connected to one end of the support rod 8 via a hinge 10, and the other end of the movable rod 9 is detachably connected to the other end of the support rod 8. This configuration facilitates cable placement. When a cable needs to be placed between the pressure wheel 7 and the guide wheel 6, the movable rod 9 is rotated to separate the pressure wheel 7 from the guide wheel 6. Then, the cable is placed on the guide wheel 6, and the movable rod 9 is rotated to connect with the support rod 8. At this point, the cable is pressed firmly against the guide wheel 6 by the pressure wheel 7.

[0027] Specifically, the movable rod 9 is provided with an elastic locking block 11, and the support rod 8 is provided with a locking groove 12, with the elastic locking block 11 locking into the locking groove 12. Through the above arrangement, a detachable connection between the movable rod 9 and the support rod 8 can be achieved, which is convenient for disassembly and assembly and has a good connection effect, making it easy for the pressure roller 7 and the guide roller 6 to fix the cable.

[0028] In this embodiment, the guide wheel 6 is provided with a "V"-shaped fixing groove 13, and the pressure wheel 7 is provided with a "V"-shaped protrusion 14, which is disposed in the fixing groove 13. The "V"-shaped fixing groove 13 facilitates the placement of the cable in the middle of the guide wheel 6 for easy fixing, and also prevents the cable from easily detaching from the fixing groove 13 during movement, thus facilitating cable measurement. The "V"-shaped protrusion 14 fits snugly against the fixing groove 13, improving the cable's fixation effect within the fixing groove 13, preventing the cable from falling out of the fixing groove 13, and ensuring that the cable remains in the middle of the fixing groove 13 at all times.

[0029] As one implementation, the movable rod 9 is equipped with a rotating shaft 15, and the pressure roller 7 is equipped with a sleeve 16. The sleeve 16 is fitted onto the rotating shaft 15 and rotatably connected to the rotating shaft 15. Through the above arrangement, the rotation of the pressure roller 7 is realized, and the cooperation between the sleeve 16 and the rotating shaft 15 can also improve the rotation effect, allowing the pressure roller 7 to be made of flexible materials such as rubber without affecting the rotation.

[0030] Specifically, the movable rod 9 is equipped with a slider 17, which is slidably connected to the movable rod 9. A spring 18 is provided between the slider 17 and the movable rod 9, and the rotating shaft is located on the slider 17. With the above arrangement, the pressure roller 7 can always apply a certain force to the cable under the action of the spring 18, thereby improving the cable fixing effect and avoiding damage to the cable due to excessive pressure.

[0031] In this embodiment, the slider 17 is provided with a fixing hole 19, and the rotating shaft is disposed in the fixing hole 19. One end of the rotating shaft is provided with a fixing piece 20, and the other end of the rotating shaft is provided with a connecting piece 21. The connecting piece 21 is threadedly connected to the rotating shaft. With the above arrangement, the rotating shaft can be easily disassembled and assembled, and the pressure roller 7 can be easily disassembled, assembled, and replaced. The pressure roller 7 can be replaced after wear, and pressure rollers of different materials and shapes can be replaced according to different types of cables to ensure the cable fixing effect.

[0032] As one implementation method, the pressure roller 7 is made of a flexible material. This design improves the fit between the pressure roller 7 and the guide roller 6, enhancing cable fixation and preventing cable damage. Flexible materials include rubber, plastic, and expandable polystyrene board.

[0033] As one implementation method, the outer side of the pressure roller 7 is provided with several protruding ribs 22. This arrangement can increase the friction between the pressure roller 7 and the cable, effectively preventing slippage.

[0034] As one implementation, a pad 23 is provided at the top of the support rod 8. This arrangement improves the connection between the support rod 8 and the movable rod 9 bracket, preventing wobbling and thus enhancing the clamping effect of the pressure roller 7.

[0035] The base 1 of this invention is equipped with a guide assembly 4, which is located between the laser emitting device 2 and the laser receiving device 3. The guide assembly 4 includes a fixed frame 5, a guide wheel 6, and a pressure wheel 7. The guide wheel 6 and the pressure wheel 7 are both mounted on the fixed frame 5 and rotatably connected to it, with the guide wheel 6 and the pressure wheel 7 in close contact. Through the cooperation of the guide wheel 6 and the pressure wheel 7, this invention can fix and tension the cable to be measured, thereby allowing continuous cable movement for measurement, improving measurement accuracy and effect, and facilitating continuous measurement.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
