[0039] The following will mainly describe the specific structure of the handheld intelligent colorimeter.

[0040] Reference Figures 1 to 11 In an embodiment of the present invention, the handheld intelligent colorimeter includes an angle frame 2 and a colorimeter body 3, wherein the angle frame 2 includes:

[0041] A base 21, wherein the base 21 has a mounting position;

[0042] A sliding frame 22, the sliding frame 22 is located above the base 21, and the sliding frame 22 includes a connecting end and a movable end, the connecting end is rotatably connected to the mounting position on the base 21, so that the movable end is close to or away from the base 21;

[0043] A driving mechanism 23, wherein the driving mechanism 23 is fixedly mounted on the sliding frame 22;

[0044] The colorimeter body 3 is mounted on the sliding frame 22 and connected to the driving structure, so that the colorimeter body 3 can slide along the length direction of the sliding frame 22 under the drive of the driving structure.

[0045] Specifically, in this embodiment, the shape of the sliding frame 22 can be many, such as a cube, a cylinder, a cuboid, etc. In this embodiment, a cuboid is taken as an example. There are many options for the rotational connection between the sliding frame 22 and the base 21, such as the rotational connection between the two can be achieved by rotating the hinge.

[0046] When in use, the colorimeter body 3 is mounted on the sliding frame 22 and connected to the driving structure, and the connecting end of the sliding frame 22 is mounted on the mounting position of the base 21. The position of the movable end of the sliding frame 22 is adjusted by rotating according to the position of the measured object, that is, the angle formed by the sliding frame 22 and the base 21 can be adjusted so that the colorimeter body 3 mounted on the sliding frame 22 can determine the detection area according to the demand, and the driving mechanism 23 is turned on so that the driving structure drives the colorimeter body 3 to slide along the length direction of the sliding frame 22. The colorimeter body 3 measures the color of the measured object during the sliding process to obtain multiple measurement data. It can be understood that there is a certain distance between the colorimeter body 3 and the detected object, so that the colorimeter has a certain detection area, so that the colorimeter body 3 can detect the same position from different angles during the sliding process, and can also detect different positions of the object from the same angle. It is worth noting that the angle formed by the sliding frame 22 and the base 21 can also be adjusted so that the colorimeter body 3 mounted on the sliding frame 22 can measure the color of the measured object at different angles.

[0047] There are many ways to realize that the driving structure drives the colorimeter body 3 to slide along the length direction of the sliding frame 22, and an example is given below to illustrate.

[0048] The sliding frame 22 includes a sliding frame body 221, and a sliding groove is provided on the sliding frame body 221 along the length direction of the sliding frame 22; the driving mechanism 23 includes a stepping motor 231, an auxiliary transmission rod 232 and a transmission belt 233, the stepping motor 231 and the auxiliary transmission rod 232 are respectively located at two opposite ends of the sliding frame body 221, the transmission belt 233 connects the output shaft of the stepping motor 231 and the auxiliary transmission rod 232, and the transmission belt 233 is located below the sliding groove and arranged along the length direction of the sliding groove; a sliding block 313 is provided at the bottom of the colorimeter body 3, and the sliding block 313 is clamped in the sliding groove and connected to the transmission belt 233, so that the sliding block 313 slides along the length direction of the sliding groove 224 under the drive of the transmission belt 233. In this embodiment, there are many ways to connect the transmission belt 233 and the sliding block 313, such as connecting by screws, fixing the two by a cable tie, or connecting by buckle. When in use, the stepper motor 231 is turned on, and the transmission belt 233 is transmitted between the stepper motor 231 and the auxiliary transmission rod 232. During the transmission process, the transmission belt 233 drives the sliding block 313 of the colorimeter body 3 to slide along the length direction of the sliding groove, thereby making the colorimeter body 3 slide along the length direction of the sliding frame 22.

[0049] In this embodiment, the sliding frame 22 is rotatably connected to the base 21, and the colorimeter is installed on the sliding frame 22, so that people can change the position of the colorimeter body 3 by rotating the sliding frame 22, so that the colorimeter body 3 can measure the color of the object to be measured from multiple angles, and a driving structure is installed on the sliding frame 22, and the colorimeter body 3 is connected to the driving structure, so that the colorimeter body 3 can slide along the length direction of the sliding frame 22 under the drive of the driving structure, so that the colorimeter body 3 can continuously and quickly measure the color of the object from multiple angles, which is conducive to people to obtain representative color data through multiple color data, avoids the influence of different measurement angles on the measurement results, and improves the accuracy of the colorimeter measurement as a whole. In addition, during the sliding process, the colorimeter body 3 can also measure different positions of the object at the same angle. When measuring an object with a constantly changing color, different color data at different positions can be continuously and efficiently measured, so that people can analyze and process the color data conveniently, thereby improving the applicability of the colorimeter.

[0050] In this embodiment, the connecting end of the sliding frame 22 is connected to the end of the base 21, and the end of the base 21 is provided with an angle mark. The connecting end of the sliding frame 22 is provided with an angle pointer 225, one end of the angle pointer 225 is connected to the connecting end, and the other end extends to the angle mark, and swings on the angle mark as the sliding frame 22 rotates to indicate the size of the angle formed between the sliding frame 22 and the base 21. The provision of the angle mark and the angle pointer 225 facilitates the user to adjust and record the angle between the sliding frame 22 and the base 21.

[0051] In this embodiment, a telescopic rod 213 is also installed at one end of the base 21 away from the connecting end. One end of the telescopic rod 213 is rotatably connected to the base 21, and the other end extends to the movable end of the sliding frame 22 and abuts against the movable end to support the movable end. It is understandable that the length of the telescopic rod 213 and / or the position direction between the telescopic rod 213 and the base 21 can be adjusted according to demand, so that the telescopic rod 213 can support the movable end, thereby improving the stability between the sliding frame 22 and the base 21. Furthermore, the stability between the telescopic rods 213 can be improved by tightening the screws 214, and the stability between the sliding frame 22 and the base 21 can be further improved. In some embodiments, the length and angle of the telescopic rod 213 can be adjusted by remote control to replace the manual adjustment method to improve work efficiency.

[0052] In this embodiment, the sliding frame 22 further includes a mounting platform 222, and the mounting platform 222 is provided at one end of the sliding frame body 221. An electromagnetic wave rangefinder 223 is installed on the mounting platform 222. The electromagnetic wave rangefinder 223 is provided corresponding to the colorimeter body 3 and is used to measure the sliding distance of the colorimeter body 3 in the sliding groove. The electromagnetic wave rangefinder 223 can measure the sliding distance of the colorimeter body 3 in real time through the provision of the electromagnetic wave rangefinder 223, so as to facilitate the user to record. If necessary, the user can combine the sliding distance with the measured color data for color analysis.

[0053] In this embodiment, a straight baffle 226 is further provided at one end of the sliding frame body 221 away from the mounting platform 222. The straight baffle 226 is arranged opposite to the mounting platform 222 and is located at the end of the sliding track of the colorimeter body 3. A limit switch 227 is provided on the inner side of the straight baffle 226 facing the mounting platform 222. The limit switch 227 is electrically connected to the stepper motor 231. When the colorimeter body 3 touches the limit switch 227, the stepper motor 231 stops working, and the transmission belt 233 stops driving the colorimeter body 3 to slide, thereby preventing the colorimeter body 3 from falling off the sliding frame 22, thereby improving the safety of the colorimeter body 3.

[0054] In this embodiment, the colorimeter body 3 includes a colorimetric frame 31, a main recognition head 32 and a sub-recognition head 33. The bottom of the colorimetric frame 31 is connected to the driving structure. The main recognition head 32 is located in the middle of the test frame and communicates with the outside. The sub-recognition head 33 is installed on the top of the colorimetric frame 31 and is rotatably connected to the colorimetric frame 31. When in use, the user can use only the main recognition head 32 or use both the main recognition head 32 and the sub-recognition head 33 according to actual needs. The rotatable connection setting of the sub-recognition head 33 and the colorimetric frame 31 is conducive to the user to adjust the angle of the main recognition head when necessary to ensure that the main recognition head 32 and the sub-recognition head 33 perform color measurement on the same position of the measured object.

[0055] Furthermore, an illumination lamp 311 and an auxiliary color lamp 312 are also provided on the color measuring frame 31. Both the illumination lamp 311 and the auxiliary color lamp 312 are located below the main recognition head 32. There are at least two auxiliary color lamps 312, which are respectively located on both sides of the illumination lamp 311. The arrangement of the illumination lamp 311 is conducive to the main recognition head 32 and the auxiliary recognition head 33 to better measure the object to be measured in the case of poor light, and the auxiliary color lamp 312 can facilitate the user to perform detection in some special cases.

[0056] In this embodiment, the handheld intelligent colorimeter further includes a carrying case 1, which includes a case body 11 and a case cover 12. The case body 11 can be used to accommodate the angle bracket 2 and the colorimeter body 3. The case cover 12 is disposed on the upper portion of the case body 11 and is rotatably connected to the case body 11 to cover the case body 11. The outer side of the case body 11 is further provided with a handle 112, which is rotatably connected to the case body 11. The angle bracket 2 and the colorimeter body 3 are accommodated in the carrying case 1 for easy carrying.

[0057] In this embodiment, the bottom wall of the box 11 is provided with a slot 111 penetrating the box 11, the two ends of the base 21 are provided with supporting feet, and the middle part is provided with a supporting block 211, and the length of the supporting feet is greater than the length of the supporting block 211, so that when the supporting feet are clamped in the slot 111, the supporting block 211 abuts against the bottom of the box 11, and the supporting feet partially extend out of the box 11. Specifically, the supporting block 211 and the base 21 are integrally formed, which is conducive to the overall stability of the base 21, and the supporting feet of the base 21 extend out of the box 11 to avoid direct contact between the box 11 and the ground, reducing the wear of the box 11, and the setting of the supporting block 211 is conducive to ensuring the stability between the base 21 and the box 11.
