Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a handheld gas leak detector. Background Art

[0002] A gas leak detector is a device used to monitor whether there are harmful gases or combustible gases in the air. They are usually used in industrial sites, laboratories, storage facilities, mines and other environments, as well as some household environments, such as around kitchens and heating equipment. When the detector detects that the concentration of harmful gases or combustible gases exceeds the safe range, it will issue an alarm so that timely measures can be taken, such as ventilation or shutting down relevant equipment, to ensure the safety of personnel and property.

[0003] Although the current handheld gas leak detectors play an important role in detection, their detection range is limited. Since they cannot extend a long distance, in some cases, they cannot detect the position to be measured, which is a problem for some special occasions. In addition, the designs of some handheld gas leak detectors lack effective protection measures for the buttons. This means that if the buttons are accidentally touched and not noticed in time, it is possible to record incorrect data. Summary of the Utility Model

[0004] In order to solve the above various problems, the utility model proposes a handheld gas leak detector with a relatively long detection distance and protection against accidental touch of the buttons on the instrument.

[0005] In order to solve the above technical problems, the technical solution proposed by the utility model is: a handheld gas leak detector, comprising:

[0006] An upper housing, on the upper end of the front surface of which is provided a display screen, on the front surface of which is pasted an anti-collision sticker strip, and on the lower end of the front surface of which is provided a calibration area with a calibration button;

[0007] On the upper end of the rear surface of the lower housing is provided a pressing clip for fixation, on one side of the upper surface of the lower housing is connected with a telescopic rod, and the extending end of the telescopic rod is connected with a detection probe;

[0008] A calibration housing, on both sides of the calibration area are provided card slots, in which the calibration housing is snap-fitted, in the middle of the calibration housing is provided a circular blocking piece for blocking the calibration area, and on the calibration housing and on one side of the circular blocking piece is provided a rotating shaft.

[0009] Further, the anti-collision sticker strip is pasted on the four sides of the display screen.

[0010] Based on the above technical features, the display screen is sandwiched between the anti-collision sticker strips to prevent accidental dropping and damage to the display screen.

[0011] Further, a switch button is provided in front of the upper housing and below the display screen, and a charging port and a sound hole are provided below the upper housing.

[0012] Based on the above technical features, the present handheld gas leak detector is convenient to operate.

[0013] Further, a storage battery and a circuit board are provided inside the upper housing and the lower housing.

[0014] Further, a return spring is provided between the pressing clip and the lower housing, and the pressing clip is in close fit with the lower housing in the natural state.

[0015] Based on the above technical features, when it is necessary to hang the present design somewhere, it can be easily realized. Just press the pressing clip to open it and attach it to the desired fixing place.

[0016] Further, two arc-shaped grooves are oppositely arranged in the correction area, depression holes are provided on the arc-shaped grooves, and the correction button is arranged in the depression holes and protrudes out of the depression holes.

[0017] Based on the above technical features, the correction button is convenient to press. Even if the button cannot be seen, it can be felt along the arc-shaped groove, which is relatively simple and convenient.

[0018] The advantages of the present utility model compared with the prior art are as follows:

[0019] Far detection distance: The present handheld gas leak detector is equipped with a telescopic rod. When the position to be detected is far away, the user can extend the length of the detection probe by pulling out the telescopic rod, thereby increasing the detection distance. This makes it more convenient and effective to detect gas leaks in places that are difficult to approach.

[0020] Anti-misoperation of the buttons on the instrument: A correction shell is provided to block most of the buttons, and only the switch button is left outside to prevent incorrect detection data caused by accidentally touching the buttons. BRIEF DESCRIPTION OF THE DRAWINGS

The anti-collision sticker 5 is pasted on the four sides of the display screen 4. The display screen 4 is sandwiched between the anti-collision stickers 5 to prevent accidental dropping and damage to the display screen. A switch button 11 is provided on the front surface of the upper housing 1 and below the display screen 4, and a charging port and a sound hole are provided on the lower surface of the upper housing 1, making this handheld gas leakage detector easy to operate.

[0028] Combined with the attached Figure 2 , a fixing pressing clip 7 is provided at the upper end of the rear surface of the lower housing 2, a telescopic rod 8 is connected to one side of the upper surface of the lower housing 2, and a detection probe 9 is connected to the extending end of the telescopic rod 8. A storage battery and a circuit board are provided inside the upper housing 1 and the lower housing 2. A return spring is provided between the pressing clip 7 and the lower housing 2. The pressing clip 7 is in close fit with the lower housing 2 in the natural state, making it very easy to implement when this design needs to be hung somewhere. Just press the pressing clip 7 to make it open and attach it to the desired fixing place.

[0029] Combined with the attached Figure 4 , a calibration housing 3, card slots 10 are provided on both sides of the calibration area 6, the calibration housing 3 is snap-fitted in the card slots 10, a circular blocking piece for blocking the calibration area 6 is provided in the middle of the calibration housing 3, and a rotating shaft is provided on the calibration housing 3 and on one side of the circular blocking piece.
