[0002] Image measuring instrument, also known as precision image surveying instrument, overcomes the shortcomings of traditional projectors and is a new type of high-precision, high-tech measuring instrument that integrates optical, mechanical, electrical and computer image technology. The optical microscope performs high-magnification optical magnification imaging on the object to be measured, and after the magnified object image is sent to the computer through the CCD camera system, it can efficiently detect the contour and surface shape, size, angle and position of various complex workpieces, especially the microscopic inspection and quality control of precision parts.

[0003] Image measuring instruments have relatively high requirements for the operating environment. The electronic instruments in the instrument (such as CCD cameras) need to prevent external dust from falling in. However, image measuring instruments are directly exposed to the outside world and do not have a good dust-proof structure, resulting in poor dust-proof effect. After long-term use, the instrument accuracy will be reduced or even damaged. Utility Model Content

[0026] A dust cover 2 is hingedly provided outside the measuring instrument body 11 to isolate dust, and the product is placed through the placement opening 5 when in use. At the same time, the dust removal structure 3 is provided to prevent dust from entering through the opened placement opening 5, thereby ensuring that the measuring instrument body 11 is protected from dust intrusion, which may affect the measurement accuracy or even be damaged.

[0027] In another embodiment, see Figures 1 to 3The dust removal structure 3 includes a suction fan 31, which is fixedly arranged on the top of the dust cover 2. An air inlet 12 is arranged on the outer top of the dust cover 2 corresponding to the suction fan 31. A dustproof mesh cover 32 is threadedly connected to the air inlet 12 for easy disassembly and cleaning in the later stage. An inverted U-shaped air guide plate 33 is arranged on the upper side of the measuring instrument body 11. The front and rear ends of the inverted U-shaped air guide plate 33 are fixed on the front and rear side walls inside the dust cover 2. The inverted U-shaped air guide plate 33 is arranged to prevent the wind sucked by the suction fan 31 from directly blowing on the measuring instrument body 11, and to prevent it from being contaminated by dust as much as possible. It cooperates with the placement port 5 to form air convection, thereby preventing dust from entering the dust cover 2 from the placement port. A lamp tube 7 is arranged in the inverted U-shaped air guide plate 33 corresponding to the measuring instrument body 11, so that the internal situation of the dust cover 2 can be better observed.
