DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4, the utility model provides an adjustable profile measuring instrument, which includes a base 1, a lifting device 2, a transverse movement device 3, a mounting frame 4 and an optical measuring device main body 5. The lifting device 2 is fixedly installed at the rear side of the base 1. The transverse movement device 3 is arranged on the base 1. The mounting frame 4 is arranged above the base 1 through the lifting device 2. An installation groove 401 is formed inside the mounting frame 4. A convex block 501 is arranged on the surface of the optical measuring device main body 5 corresponding to the installation groove 401. The optical measuring device main body 5 is slidably arranged inside the mounting frame 4 through the convex block 501. An installation mechanism 6 is arranged on the mounting frame 4 to limit the optical measuring device main body 5. A moving block 701 is slidably connected to the threaded rod inside the transverse movement device 3 on the base 1. A placing device 7 is fixedly connected to the upper part of the moving block 701. A rotating mechanism 8 is arranged between the placing device 7 and the moving block 701 to rotate and adjust the placing device 7.

[0023] By operating the lifting device 2, it is convenient to adjust the height position of the optical measuring device main body 5, and then it is convenient to adjust the optical measurement according to the optical measuring object placed on the placing device 7. At the same time, by operating the transverse movement device 3, it is convenient to drive the moving block 701 to slide on the base 1 through the threaded rod. While the moving block 701 slides, the placing device 7 is driven to slide on the base 1, and then the optical measuring object moves, so as to facilitate the optical measurement work. The lifting device 2, the transverse movement device 3, the mounting frame 4, the optical measuring device main body 5 and the placing device 7 have been specifically disclosed in the patent with the patent publication number CN221198348U, and will not be elaborated here too much.

[0024] Furthermore, as shown in Figure 1 , Figure 2 and Figure 4 , it is specifically noted that the rotating mechanism 8 includes a connecting shaft 801. The connecting shaft 801 is fixedly connected to the bottom of the placing device 7. The bottom end of the connecting shaft 801 is rotatably installed with a bearing seat 802 and fixedly installed on the upper part of the moving block 701. A gear 803 is fixedly connected to the outside of the connecting shaft 801. A rack 804 is fixedly connected to the base 1 outside the gear 803. There are two racks 804, and the two racks 804 are symmetrically arranged about the center on the base 1, and the two racks 804 are arranged at intervals.

[0025] During use, when the gear 803 meshes with the rack 804 during the movement of the moving block 701, the gear 803 will be rotated to drive the connecting shaft 801 to rotate, and then the placing device 7 will be rotated, so that the optical measuring object will be rotated, and then it is convenient to perform a comprehensive optical measurement work through the optical measuring device main body 5. When running to the other rack 804, through the meshing of the rack 804 and the gear 803, the gear 803 will be driven to rotate in the reverse direction, and then the optical measuring object on the placing device 7 will be rotated in the reverse direction to return to the original position, so that the optical measuring device main body 5 can further perform optical measurement work on it, and then improve the accuracy of the optical measurement work.

[0026] According to the above working process, it can be known that: through the rotation mechanism 8 provided, in cooperation with the placement device 7 for placing the optical measurement object, when the optical measurement work is carried out on it by the optical measurement equipment main body 5, the automatic rotation work of the optical measurement object can be realized through the movement measurement work of the transverse movement device 3, thereby improving the comprehensiveness of the optical measurement process and improving the measurement efficiency.

[0027] Further, as shown in Figure 1 , Figure 2 and Figure 3 It is worth specifically explaining that the installation mechanism 6 includes a support plate 601. The support plate 601 is slidably arranged in the installation frame 4 in a matching manner and is arranged inside the installation frame 4. A positioning rod 602 is fixedly connected to the rear surface of the support plate 601. A matching positioning port 603 is provided on the rear side of the positioning rod 602 corresponding to the installation frame 4 and the lifting device 2. A first spring 604 is sleeved outside the positioning rod 602 on the rear side of the support plate 601, and the positioning rod 602 is slidably arranged in the positioning port 603.

[0028] Further, as shown in Figure 1 , Figure 2 and Figure 3 It is worth specifically explaining that the installation mechanism 6 further includes two installation ports 605. The two installation ports 605 are symmetrically arranged left and right on the installation frame 4 and are arranged in front of the convex block 501. A block 606 is penetrated and slidably arranged in the installation port 605. A sliding rod 607 is slidably arranged outside the block 606 on the installation frame 4. The sliding rod 607 is fixedly connected to the surface of the installation frame 4. A second spring 608 is sleeved outside the sliding rod 607 and is arranged on the outer side of the block 606. A pull block 609 is fixedly connected to the outer surface of the block 606. The block 606 penetrates through the installation port 605 to the inside of the installation frame 4 and is arranged in front of the convex block 501. There are two sliding rods 607 arranged on the block 606 and are arranged at intervals up and down. Both ends of the second spring 608 are connected to the block 606 and the sliding rod 607 respectively.

[0029] During use, by pulling the pull block 609, the block 606 slides on the sliding rod 607 to squeeze the second spring 608, so that the block 606 slides to release the limit on the front part of the optical measurement equipment main body 5. Furthermore, under the elastic force of the first spring 604, the support plate 601 ejects the optical measurement equipment main body 5, so as to facilitate taking out and disassembling the optical measurement equipment main body 5 from the inside of the installation frame 4, so as to facilitate maintenance and cleaning, and improve the practicability of the device.

[0030] This solution has the following working process: When this device is in use, the lifting device 2 operates to facilitate the adjustment of the height position of the optical measurement device main body 5, and thus facilitate the optical measurement according to the optical measurement object placed on the placement device 7. At the same time, the transverse movement device 3 operates to facilitate the sliding of the moving block 701 on the base 1 driven by the threaded rod. While the moving block 701 slides, it drives the placement device 7 to slide on the base 1, thereby moving the optical measurement object to facilitate the optical measurement work. At the same time, during the movement of the moving block 701, when the gear 803 meshes with the rack 804, the gear 803 will rotate to drive the connecting shaft 801 to rotate, and then the placement device 7 will rotate, so that the optical measurement object rotates, and thus facilitate the comprehensive optical measurement work through the optical measurement device main body 5. When it runs to the rack 804 on the other side, the rack 804 meshes with the gear 803, which will drive the gear 803 to rotate in the reverse direction, and then the optical measurement object on the placement device 7 will rotate in the reverse direction and return to its original position, so that the optical measurement device main body 5 can further perform optical measurement work on it, thereby improving the accuracy of the optical measurement work. And by pulling the pull block 609, the stop block 606 slides on the slide rod 607 to squeeze the second spring 608, so that the stop block 606 slides to release the front limit of the optical measurement device main body 5. Then, under the elastic force of the first spring 604, the support plate 601 pushes out the optical measurement device main body 5, so as to facilitate the removal and disassembly of the optical measurement device main body 5 from the inside of the installation frame 4, so as to facilitate maintenance and cleaning and improve the practicality of the device.

[0031] In summary: By setting the rotating mechanism 8 and cooperating with the placement of the optical measurement object by the placement device 7, when performing optical measurement work on it through the optical measurement device main body 5, the automatic rotation work of the optical measurement object can be realized through the movement measurement work of the transverse movement device 3, thereby improving the comprehensiveness of the optical measurement process and the measurement efficiency. Through the installation frame 4 cooperating with the convex block 501 provided on the optical measurement device main body 5, it is convenient to carry out stable installation work. At the same time, through the installation mechanism 6 provided on it, it is convenient to quickly and efficiently realize the disassembly and assembly process of the optical measurement device main body 5, and thus facilitate the maintenance and cleaning of the optical measurement device main body 5 to improve its accuracy in the measurement work.
