Description

Technical Field

[0001] The utility model relates to the technical field of infrared thermometers, and more specifically, to a handheld infrared thermometer. Background Art

[0002] Infrared temperature measurement technology plays an important role in product quality control and monitoring, online equipment fault diagnosis and safety protection, and energy conservation during the production process. In the past 20 years, non-contact infrared body thermometers have developed rapidly in technology, with continuous improvement in performance, enhancement of functions, increase in variety, and expansion of application scope.

[0003] At present, the existing handheld infrared thermometers are usually provided with a lens at the detection end, which protects the internal components and does not hinder the normal use of the infrared sensor. In addition, a protective cover is provided to protect the lens. However, similar to the above-mentioned handheld infrared thermometer, when the protective cover is closed, the dust on the surface of the lens cannot be cleaned. Therefore, before each use, the lens needs to be cleaned to prevent the dust from affecting the detection of the instrument, which is inconvenient. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a handheld infrared thermometer. The utility model has the advantages that the protective cover can protect the lens and clean the dust on the lens surface at the same time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a handheld infrared thermometer, comprising a thermometer body, a protective cover is provided at the detection end of the thermometer body, a connecting plate is fixedly connected to the bottom of the protective cover, a mounting plate is fixedly connected to the bottom of the detection end of the thermometer body, the connecting plate is rotatably connected to the mounting plate through an axle, the axle is arranged in a direction perpendicular to the protective cover, a snap mechanism is arranged between the top of the protective cover and the top of the detection end of the thermometer body, a placement groove is provided on the side of the protective cover close to the thermometer body, and a cleaning cloth is arranged in the placement groove.

[0006] In a preferred embodiment, the snap mechanism includes a fixed block fixedly connected to the top of the detection end of the thermometer body, the fixed block is provided with an arc-shaped slide groove at one end close to the protective cover, a limiting groove is provided at the top of the slide groove, the top of the protective cover is fixedly connected with a connecting block, the connecting block is provided with a movable groove at one end close to the fixed block, and a limiting block adapted to the limiting groove is slidably connected in the movable groove.

[0007] In a preferred embodiment, one side of the limit block is designed to be inclined.

[0008] In a preferred embodiment, a limiting spring is fixedly connected between the bottom of the limiting block and the movable groove.

[0009] In a preferred embodiment, a connection port is formed in one end of the movable groove away from the fixed block, a pull plate is slidably connected to the inner wall of the connection port, and the pull plate is fixedly connected to the limit block.

[0010] In a preferred embodiment, a plurality of mounting grooves are formed at the bottom of the placement groove, and the cleaning cloth is fixedly connected to a plurality of adsorption blocks that are inserted into the mounting grooves in a one-to-one correspondence.

[0011] In a preferred embodiment, an adsorption magnet is fixedly connected in the mounting groove, and the adsorption block is made of magnetic material.

[0012] The beneficial effects of the utility model are:

[0013] 1. When using the utility model, first open the buckle mechanism. Since the connecting plate and the mounting plate are rotatably connected, the protective cover can be rotated to the bottom of the lens. At this time, the instrument is used normally. When the protective cover is rotated, the cleaning cloth in the protective cover will rub against the lens, thereby cleaning the dust on the lens. The staff does not need to clean the lens again. The operation is simple and easy to use.

[0014] 2. In the utility model, when closing the protective cover, the protective cover can be rotated. When the connecting block is turned to correspond to the fixed block, the arc-shaped slide groove squeezes the inclined surface of the limit block to move the limit block downward. When the limit block corresponds to the limit groove, the limit spring pushes the limit block into the limit groove to limit the protective cover. When using the instrument, the pull plate can be pressed to drive the limit block downward through the pull plate, and the protective cover can be rotated again. The operation is simple and convenient for opening and closing the protective cover.

[0015] 3. In the utility model, when the cleaning cloth needs to be replaced and cleaned, the cleaning cloth can be pulled. During installation, the adsorption block is inserted into the installation slot, and the adsorption block made of magnetic material is adsorbed by the adsorption magnet to prevent the cleaning cloth from easily leaving the placement slot, thereby achieving the purpose of facilitating the replacement and cleaning of the cleaning cloth.
