Description

Technical Field

[0001] The utility model relates to the field of electric spark detection equipment, in particular to an electric spark detector with the function of preventing electric spark sputtering. Background Art

[0002] The spark detector, also known as the spark leak detector, is an instrument used to detect defects such as pinholes and sand holes in thicker non-conductive coatings on metal substrates. The instrument is simple to use, with one end grounded and the other end being a probe. The probes come in a variety of forms, including carbon brush type, circle spring type, and flat rubber type, etc., to adapt to different working environments and workpieces. The spark detector emits DC high voltage electricity through a high-voltage probe. When the probe passes over the defective coating surface, the instrument will automatically sound and light alarms. Used to measure anti-corrosion coatings of different thicknesses. Most spark detectors are also equipped with rechargeable batteries, which are convenient for use on construction sites and in workshops. When using a spark detector, the probe must not touch the human body to avoid personal injury.

[0003] When using a spark detector to detect sparks, the inspector holds a probe and extends the probe brush to the position to be inspected for detection. The existing probe brush is generally composed of multiple groups of metal wires. During detection, the metal wires are easily bent after contacting the detection position, resulting in the inspector needing to spend time straightening the metal wires when detecting the next position, which takes a long time. At the same time, sparks appearing at the detection position are also easily splashed onto the inspector, causing harm to the inspector. For this reason, we propose a spark detector with anti-spark splashing function. Utility Model Content

[0004] The main purpose of the utility model is to provide a spark detector with anti-spark sputtering function, which can effectively solve the problems in the background technology that the metal wire on the probe brush is easily bent during detection, which takes time to straighten the metal wire and the spark sputtering can easily injure the detection personnel.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A spark detector with spark sputtering protection includes an instrument main unit for detecting sparks and a transmission cable fixedly installed at the rear end of the instrument main unit for transmitting signals, the other end of the transmission cable is fixedly connected to a handheld part, the other end of the handheld part is fixedly connected to a probe body, a pressing mechanism is installed inside the handheld part, the pressing mechanism includes an adjusting slider and an extension plate, a pressing block for pressing trigger is slidably installed in the adjusting slider, and a probe brush body is fixedly connected to the front end of the probe body.

The front end of the extension disk is fixedly connected to four groups of evenly distributed push rods. The left and right sides of the outside of the adjusting slider are slidably connected to a group of symmetrically distributed pressing blocks. The adjusting slider slides in the inner cavity of the hand-held part, so that the four groups of push rods follow the sliding. The movement of the push rod causes the rubber tube installed at the front end of the push rod to slide in the circular slide groove, thereby wrapping the metal bristles.
