Description

Technical Field

[0001] The utility model belongs to the technical field of laser diameter meters, in particular to a lens protection device for a laser diameter meter. Background Art

[0002] A laser diameter gauge is an instrument that uses a laser to measure the diameter of a workpiece or material. It is suitable for measuring materials such as wires, cables, enameled wires, optical fibers, rubber, plastics, wires, bars, pipes, and rolled steel.

[0003] In actual operation, the existing laser diameter meter has a lens that is always exposed to the outside and is affected by dust in the production workshop. After a period of use, the lens can easily become dirty, causing the laser beam emitted by the laser diameter meter to attenuate or deviate, which in turn has a great impact on the accuracy of the distance measurement data.

[0004] In view of this, a laser diameter meter lens protection device is proposed. Utility Model Content

[0007] In a preferred embodiment, the air outlet is inclined toward the lens.

[0008] In a preferred embodiment, the blowing assembly includes a micro air pump and a gas flow channel, and the gas flow channel is arranged in the housing of the laser diameter meter and is connected to the blowing port and the air outlet end of the micro air pump.

[0012] In a preferred embodiment, a PCB mainboard is also accommodated inside the laser diameter meter.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the utility model, a reversible protective cover is designed in front of the laser diameter meter. When the protective cover is flipped to the upper horizontal position, dust can be blocked from the upper part. When the laser diameter meter is finished using, the protective cover is flipped down to fit the front end of the groove. At this time, the lens can be covered by the protective cover for protection, and the lens can be prevented from being damaged or covered with dust as much as possible, thereby ensuring the protective effect of the lens;

[0015] 2. In the utility model, when dust is stuck in front of the lens, the micro air pump is controlled to work, and the lens is cleaned by the gas blown out by the air pump, thereby ensuring the normal use of the laser diameter meter to improve the measurement accuracy.
