[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0028] Reference Figures 1-4, A diameter measuring device, comprising a measuring frame 1. The inner wall of the measuring frame 1 is provided with a chute 13 of a U-shaped structure. Inside the chute 13, there is a measuring wheel 4. At the center of the measuring wheel 4, a rotating shaft 10 is fixedly connected. Both ends of the rotating shaft 10 are fixedly connected with bearings 11. The measuring wheel 4 is slidably installed inside the chute 13 through the bearings 11. A scale 9 is provided on the outer circumference of the measuring wheel 4. At the bottom end of the measuring frame 1, there is a storage mechanism. On the outside of the measuring frame 1, there is a locking mechanism for facilitating the locking of the measuring wheel 4. At the bottom of the measuring frame 1, there is a stabilizing mechanism. The measuring wheel 4 is installed in the chute 13 through the bearings 11 and can freely slide along the chute 13. And a scale 9 is provided on the outer circumference of the measuring wheel 4 for recording the sliding distance. When in use, place the measuring frame 1 on the object to be measured, make the measuring wheel 4 closely adhere to the surface of the object, then slide the measuring wheel 4 to the other side of the object, and read the scale 9 on the measuring wheel 4 through the viewing window 2 to know the diameter of the object. And a handle 6 is also provided. The overall volume of the measuring frame 1 is small, and it is convenient to carry and use the measuring frame 1 through the handle 6. And the measuring frame 1 does not require an external power supply, can adapt to the measurement work in complex environments, and has simple operation and convenient use, with better practicability.

[0029] Refer to Figure 1 , The locking mechanism includes limiting grooves 3 opened on the measuring frame 1 and located on both sides of the chute 13. Inside the limiting grooves 3, there are abutting bolts 12. One end of the abutting bolts 12 abuts against the outside of the measuring wheel 4. By adding the abutting bolts 12 on the limiting grooves 3, the position of the measuring wheel 4 is used to prevent the measuring wheel 4 from moving when reading the scale 9, thereby improving the accuracy of the object diameter measurement.

[0030] Refer to Figure 2 , The storage mechanism includes a storage groove 5 opened at the bottom of the measuring frame 1. At one end inside the storage groove 5, a shaft body is rotatably connected. On the outside of the shaft body, a handle 6 is fixedly connected. Through the setting of the storage groove 5, when in use, the handle 6 can be unfolded for easy gripping, and when not in use, the handle 6 can be folded and retracted to reduce the occupied space and further improve the portability of the measuring frame 1.

[0031] Refer to Figure 1 , The stabilizing mechanism includes a magnetic sheet 8 embedded on one side of the handle 6. An iron sheet 7 cooperating with the magnetic sheet 8 is embedded on the inner wall of the storage groove 5. The iron sheet 7 is adsorbed to the magnetic sheet 8. Through the cooperation of the magnetic sheet 8 and the iron sheet 7, the handle 6 can be fixed in the storage groove 5 to avoid the phenomenon that the handle 6 pops out during the carrying process of the measuring frame 1 and reduce the impact on portability.

[0032] Refer to Figure 3 , A viewing window 2 for facilitating the reading of the scale 9 is fixedly installed on the outside of the measuring frame 1 and below the limiting groove 3. Through this viewing window 2, the scale 9 on the measuring wheel 4 can be read, which is convenient for reading and recording.

[0033] Reference Figure 3 The outer circumference of the measuring wheel 4 is provided with anti-skid patterns for increasing friction, so as to increase the friction between the measuring wheel 4 and the inner wall of the slide groove 13, so that the measuring wheel 4 is more stable during the movement.

[0034] Reference Figure 1 The measuring frame 1, the viewing window 2 and the limiting groove 3 are all U-shaped structures. The U-shaped structure is arranged to facilitate the measurement of objects with circular cross-sections such as steel bars and pipes.

[0035] Working principle: First, the measuring wheel 4 is installed in the slide groove 13 through the bearing 11, and can slide freely along the slide groove 13, and the outer circumference of the measuring wheel 4 is provided with a scale 9 for recording the sliding distance. When in use, the measuring frame 1 is placed on the object to be measured, so that the measuring wheel 4 is close to the surface of the object, and then the measuring wheel 4 is slid to the other side of the object, and the scale 9 on the measuring wheel 4 is read through the visual window 2 to know the diameter of the object. A handle 6 is also provided, and the overall volume of the measuring frame 1 is small. The handle 6 is convenient for carrying and using the measuring frame 1, and the measuring frame 1 does not need an external power supply, can adapt to the measurement work in a complex environment, and is simple to operate, convenient to use, and has good practicality;

[0036] By adding a resisting bolt 12 to the limit groove 3 to measure the position of the measuring wheel 4, the measuring wheel 4 is prevented from moving when reading the scale 9, thereby improving the accuracy of measuring the diameter of the object. By setting the storage groove 5, the handle 6 can be unfolded for easy holding when in use, and the handle 6 can be folded and stowed when not in use, thereby reducing the occupied space and further improving the portability of the measuring frame 1.
