[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a steel bar size detector, including a load-bearing frame 1, the bottom of the load-bearing frame 1 is slidably embedded with two L-shaped brackets 3, the bottoms of the two L-shaped brackets 3 are symmetrically rotatably connected with rotating shafts 31, the bottoms of multiple rotating shafts 31 are rotatably connected with first rollers 32, the tops of the two L-shaped brackets 3 are fixedly connected with mounting frames 4 near the middle, the right surface of one mounting frame 4 is installed with a laser scanner 41, and the left surface of the other mounting frame 4 is installed with a reflecting plate 42, a limiting groove 11 is provided on the top of the load-bearing frame 1, the right surface of the load-bearing frame 1 is fixedly connected with a motor 2, the output end of the motor 2 slides through the right surface of the load-bearing frame 1 and extends to the left surface, the output end of the motor 2 is fixedly connected with a bidirectional threaded screw 21, the bottom of the load-bearing frame 1 is fixedly connected with a U-shaped bracket 5, the inner surface wall of the U-shaped bracket 5 is rotatably connected with a second roller 51, the outer surface of the bidirectional threaded screw is threaded through the outer surfaces of the two L-shaped brackets, an encoder 52 is installed on the right surface of the U-shaped bracket 5, and the outer surfaces of the two mounting frames are slidably connected with the inner surface wall of the limiting groove.

[0023] The effect achieved by the entire embodiment 1 is that when measuring the diameter of the steel bar, the motor 2 is started. Under the action of the motor 2, the two L-shaped brackets 3 on the bidirectional threaded screw 21 will move toward the middle, so that the first roller 32 will also move toward the middle until the first roller 32 can clamp the steel bar to be measured. At this time, the laser scanner 41 is turned on. Under the action of the laser scanner 41 and the reflector 42, the distance between the two L-shaped brackets 3 can be effectively measured. In the final measurement, it is only necessary to subtract the size of the inherent bracket from the distance calculated by the laser scanner 41 to obtain the accurate size of the steel bar diameter. When measuring the length of the steel bar, the entire bearing frame 1 is moved, which will drive the second roller 51 on the U-shaped bracket 5 to move. Since the U-shaped bracket 5 is provided with an encoder 52 on its surface. As the second roller 51 rotates, the encoder 52 will also rotate synchronously. The sensor in the encoder 52 will detect the number of revolutions on the encoding disk. The sensor will convert the detected information into an electrical signal, which will be transmitted to a related control system or processor to achieve counting. Therefore, under the action of the encoder 52, the length of the steel bar to be measured can be obtained by rotating the second roller 51. This is simple to operate, saves time and effort, and effectively improves the accuracy and efficiency of measurement. The limit groove 11 serves to limit the two mounting brackets 4. The mounting bracket 4 is for facilitating the installation of the laser scanner 41 and the reflector 42, and the rotating shaft 31 is for facilitating the connection between the L-shaped bracket 3 and the first roller 32.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a mounting seat 6 is fixedly connected to the top of the carrier 1, a rotating seat 61 is rotatably connected between the inner surface walls of the mounting seat 6, a rotating sleeve 62 is fixedly connected to the outer surface of the rotating seat 61, and a telescopic pull rod 63 is fixedly connected between the inner surface walls of the rotating sleeve 62.

[0025] The effect achieved by the entire embodiment 2 is that when measuring a size that is too high or too long, the telescopic rod 63 can be adjusted to the front and rear angle by rotating the rotating seat 61 on the mounting seat 6. At this time, when back and forth measurement is required or measurement is required at a higher position, the steps of manual back and forth measurement are reduced. The time-saving and labor-saving rotating sleeve 62 is to improve the rotation flexibility between the telescopic rod 63 and the rotating seat 61.

[0026] Working principle: When measuring the diameter of the steel bar, start the motor 2. Under the action of the motor 2, the two L-shaped brackets 3 will move toward the middle, and the first roller 32 will also move toward the middle to clamp the steel bar to be measured. Turn on the laser scanner 41. Under the action of the laser scanner 41 and the reflector 42, the distance between the two L-shaped brackets 3 can be effectively measured. When measuring the length of the steel bar, move the entire carrier frame 1, which will drive the second roller 51 on the U-shaped bracket 5 to move. At this time, under the action of the encoder 52, the length of the steel bar to be measured can be obtained by rotating the second roller 51. This is simple to operate, saves time and effort, and effectively improves the measurement accuracy and efficiency. When measuring dimensions that are too high or too long, the telescopic pull rod 63 can be adjusted to the front and rear angles by rotating the rotating seat 61 on the mounting seat 6. At this time, when back and forth measurement is required or measurement is performed at a higher position, the steps of manual back and forth measurement are reduced, saving time and effort.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
