Description

Technical Field

[0001] This utility model relates to the field of chemical testing equipment technology, and in particular to a portable gas chromatograph. Background Technology

[0002] With the continuous progress and development of society, gas chromatographs have been widely used in fire investigation, petroleum, chemical, biochemistry, medicine and health, food industry, environmental protection and other fields. A gas chromatograph uses an internal pump to draw sample gas from a heated tube into the injection port, where it is then carried by a carrier gas into the chromatographic column. The column, with its different retention properties for components in the mixture, separates the components, which are then sequentially introduced into the detector to obtain the detection signal for each component. This allows for quantitative and qualitative analysis of the mixture's components.

[0003] However, most existing portable gas chromatographs are integrated structures, which are large and heavy, and cannot be flexibly adjusted according to the actual situation on site. In addition, the battery usage scheme has defects. If the on-site test time is long, the battery will be depleted and the instrument needs to be stopped for charging and the measurement restarted. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] This invention provides a portable gas chromatograph, comprising a main unit, a power supply unit, and a gas source unit. The main unit can operate independently or in combination with at least one of the power supply unit and the gas source unit. It can be used in various ways depending on the field conditions, aiming for maximum weight reduction. When both power and gas sources are available at the field, only the main unit can be carried; when power is available, a combination of the main unit and the gas source unit can be carried; and when a gas source is available, a combination of the main unit and the power supply unit can be carried.

[0006] Furthermore, the main unit includes a main unit housing, with first fasteners on both sides and a first handle on the top.

[0007] Furthermore, the gas source unit includes a gas source housing, and both sides of the gas source housing are provided with a first buckle and a second fastening block, wherein the first buckle is used to detachably connect with the first fastening block.

[0008] Furthermore, the power supply unit includes a power supply housing, and both sides of the power supply housing are provided with second latches. The second latches are used for detachable connection with the first latch block or the second latch block. By connecting the latches and latch blocks to each other, the connection between the main unit, the power supply unit, and the air source unit is realized.

[0009] Furthermore, both the main unit housing and the air source housing are equipped with feet at the bottom.

[0010] Furthermore, both the air source housing and the power supply housing have positioning holes on their tops. The base feet can be placed inside these positioning holes for easy alignment of the main unit, power supply unit, and air source unit, enabling rapid assembly of the entire unit. Specifically, the base feet are aligned with and placed inside the positioning holes, and then secured with buckles and fasteners, allowing for rapid assembly of the entire unit, arbitrary splicing, and convenient operation.

[0011] Furthermore, the power supply unit also includes a battery, and the power supply housing has a placement space for the battery. The battery is placed in the placement space, and the battery has a lock hole and a second handle. By providing a second handle on the battery, the battery can be quickly pulled out of the power supply housing by pulling the second handle.

[0012] Furthermore, the opening of the placement space is equipped with a locking structure, which includes a lever, a spring, and a locking pin. The lever is fixed to the locking pin. In the unlocked state, the locking pin is configured to compress the spring in the direction of the lever's movement when the lever is turned. In the locked state, the locking pin is configured to insert into the lock hole. Specifically, turning the lever to both sides moves the locking pin out of the lock hole on the battery, allowing the battery to be removed by pulling it outwards; pushing the battery inwards allows it to be installed. This locking structure can automatically lock, enabling convenient and quick battery replacement.

[0013] Furthermore, the end of the locking pin is provided with a first inclined surface, and the lock hole is provided with a second inclined surface. The second inclined surface is configured such that when the battery is inserted, the second inclined surface pushes the locking pin, compressing the locking pin, and then when the locking pin is aligned with the lock hole, the locking pin springs back, thereby locking the battery.

[0014] Furthermore, the power supply box is equipped with a backup small battery to maintain power supply during battery replacement or battery swapping.

[0015] This utility model has the following beneficial effects:

[0016] (1) This utility model can be used in combination according to different on-site conditions. The main unit can be selected to work independently or the main unit can be combined with at least one of the power supply unit and the air supply unit to achieve the lightest possible weight reduction and reduce the size and weight of the instrument.

[0017] (2) The power supply box of this utility model is equipped with a backup small battery, which maintains power supply during battery replacement or battery swapping. The gas chromatograph does not need to be powered off and can work normally. Furthermore, multiple batteries can be used together to extend the instrument's operating time.

[0018] (3) This utility model achieves rapid assembly of the whole machine by aligning the bottom foot with the positioning hole and placing it in the positioning hole, and then fixing it with buckles and fasteners. It is also easy to operate. Attached Figure Description
