[0002] Photoelectric measurement technology is an advanced technology that uses optical fiber communication and optoelectronic devices to measure and transmit various physical quantities under high potential. It has the advantages of high precision, non-destructive measurement, fast speed, remote measurement, digitization and intelligence. Photoelectric measurement systems are divided into active systems and passive systems. Active systems transmit information by directly modulating the light emitted by the light source, while passive systems transmit information by indirectly modulating optical signals. In the field of industrial automation, photoelectric measurement technology is widely used in position detection, material detection, color detection, etc., which greatly improves production efficiency and product quality. In addition, in the field of environmental monitoring, photoelectric measurement technology also plays an important role and can quickly and accurately detect pollutants in the environment.

[0003] Photoelectric testing has high accuracy and detection efficiency. Existing photoelectric testing devices are usually equipped with lenses on the outside. The lenses are very prone to wear and tear during use, and scratches will appear when they are hit, resulting in reduced detection efficiency, which is not conducive to user use.

[0004] Therefore, it is necessary to redesign the photoelectric testing device to effectively prevent the problem that the existing photoelectric testing device is usually equipped with a lens on the outside, which is very prone to wear during use and scratches due to collision, resulting in reduced detection efficiency and inconvenience for users.

[0012] Through the above technical solution, the setting of the protection mechanism and the limit mechanism makes it easy to protect the lens of the optoelectronic device, prevent the lens from being worn, and facilitate use by users.

[0013] Furthermore, the protective mechanism includes a through hole, which is opened on both sides of the inner wall of the elliptical ring, the top and bottom of the inner wall of the through hole are fixedly connected with a vertical rod, the surface of the vertical rod is movably connected with a sliding sleeve, and the inner side of the sliding sleeve is fixedly connected with a protective plate.

[0014] Through the above technical solution, the sliding sleeve drives the protective plate to slide on the surface of the vertical rod, thereby protecting the lens of the measuring instrument and facilitating use by the user.

[0019] Furthermore, the number of the sliding sleeves is four, and the sliding sleeves are used in conjunction with the vertical rods.

[0020] Through the above technical solution, the number of the sliding sleeves is set to four, which improves the sliding stability of the protective plate and is convenient for users to use.

[0021] Furthermore, the limiting mechanism includes a clamping block, which is fixedly connected to the bottom of the protective plate, and trapezoidal blocks are fixedly connected on both sides of the clamping block. A through opening is opened at the bottom of the front side of the elliptical ring, and spring plates are fixedly connected on both sides of the inner wall of the through opening, and a special-shaped block used in conjunction with the trapezoidal block is fixedly connected to the inner side of the spring plate.

[0022] Through the above technical solution, the special-shaped block clamps the trapezoidal block, thereby clamping the clamping block, and the spring piece is used to tighten and fix it.

[0023] Furthermore, the front side of the special-shaped block is movably connected to a clamping rod via an axle pin, the front side of the clamping rod is movably connected to a square rod via an axle pin, the front side of the square rod is fixedly connected to a button, the interior of the special-shaped block is slidably connected to a positioning rod, and the outer side of the positioning rod is fixedly connected to both sides of the inner wall of the opening.

[0024] Through the above technical solution, the special-shaped blocks can be moved along the two sides of the positioning rod box through the square rods and the tightening rods, and the trapezoidal blocks are no longer limited, which is convenient for users to operate.

[0025] The above solution of the utility model includes at least the following beneficial effects:

[0026] 1. The utility model uses a card block to push the protective plate, so that the protective plate moves toward the fixed part along the sliding sleeve and the vertical rod. When the protective plate contacts the inner side of the elliptical ring and the magnet on the top of the protective plate is attracted to the magnet on the top of the elliptical ring, the card block is stopped. At this time, the lens of the measuring instrument is protected. The above operation is reversed to facilitate the use of the measuring instrument, replacing the existing protection method, thereby achieving an efficient protection effect.

[0027] 2. The utility model moves the protective plate toward the bottom, driving the clamping block and the trapezoidal block to press against the special-shaped block, so that the movable block moves to both sides along the positioning rod and compresses the spring sheet at the same time. When the trapezoidal block enters the inner side of the special-shaped block, the spring sheet expands and resets, so that the special-shaped block clamps and fixes the trapezoidal block, thereby fixing the protective plate. If you want to open it, press the button and the square rod to make the square rod press against the clamping rod, so that the two sides of the special-shaped block move, take out the trapezoidal block, and open it.

When the protective plate 34 contacts the inner side of the elliptical ring 2 and the magnet 35 on the top of the protective plate 34 is attracted to the magnet 35 on the top of the elliptical ring 2, the pushing of the block 36 is stopped. At this time, the lens of the measuring instrument 1 is protected. The above operation is reversed to facilitate the use of the measuring instrument 1, replacing the existing protection method, thereby achieving an efficient protection effect.
