Description

Technical Field

[0001] This utility model relates to the technical field of oxygen content detection equipment, and in particular to a combined oxygen content detector. Background Technology

[0002] Oxygen detectors are commonly used to detect the oxygen content in enclosed spaces. Also known as oxygen detection alarms, they are portable personal gas detectors. Their sensors are electrochemical sensors that draw in outside air through an air pump to achieve detection. When the ambient concentration is too high, they trigger high-limit, low-limit, light, and vibration alarms to warn personnel to evacuate the danger zone as soon as possible.

[0003] Existing oxygen content detection devices are small and portable, but they are not easy to fix on the arm. During use, the detection device is easily dropped and broken due to carelessness, which will affect the accuracy of the detection and cause harm to personnel. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a combined oxygen content detector. By screwing a detachable extension hose onto the air inlet, it can extract gas from distant or enclosed spaces, increasing the application scenarios of the oxygen content detector. The detector body can also be detachably connected to a combined shoulder strap, which allows the detector to be held in hand or fixed to the arm for easy carrying. The back of the detector is also provided with a hanging groove, which, together with a wall-mounted bracket, allows the detector to be hung on the wall for detecting air quality in a fixed area. At the same time, the detector is also easy to pick up and read.

[0006] This utility model provides a combined oxygen content detector, including a detector body with grooves on both sides, a combined shoulder strap detachably connected between the two grooves, an air inlet located on the top of the detector body, and an extension hose screwed to the air inlet; the air inlet has threads on its outer side, and the extension hose has an adapter at its end, which is fitted onto and screwed to the air inlet; one side of the detector body has a fastening opening on the groove, and the other side of the detector body has a pull ring groove, in which a pull ring is rotatably connected; one side of the combined shoulder strap is fastened to the fastening opening, and the other side of the combined shoulder strap passes through the pull ring and is then fixed.

[0007] The grooves on both sides of the detector body provide space for the installation of the combination shoulder strap. After installation, the combination shoulder strap can fix the detector on the user's arm, making it convenient for the user to carry and freeing up their hands. The air pump port on the top works with the air pump inside the detector to draw in and detect the surrounding air. The extension hose, which is fitted onto and screwed to the air pump port, allows the detector to detect air in distant or enclosed spaces, increasing the detector's application scenarios. The combination shoulder strap and buckle are detachable, and the user can choose whether to install the combination shoulder strap according to actual needs. The pull ring is hidden in the pull ring groove and can be turned out from the groove to fix the combination shoulder strap when needed.

[0008] In some embodiments, the fastening opening includes an inner cavity, a top opening, and a side opening. The inner cavity is provided inside the fastening opening, and the top opening is formed at the top of the fastening opening, through which the inner cavity communicates with the outside. The side opening is formed on the side of the fastening opening, through which the inner cavity communicates with the outside. The inner cavity is used to accommodate the fastening block, the side opening is used to facilitate the insertion and release of the fastening block, and the top opening provides space for the movement of the shoulder strap, allowing it to turn freely.

[0009] In some embodiments, the side opening faces the front of the detector body. Since the detector is fixed to the arm, the display surface of the detector should face outwards; accordingly, the direction of the side opening is set to prevent the fastening block from falling off under force.

[0010] In some embodiments, a fastening block is provided on one side of the combined shoulder strap. The fastening block is made of elastic material and is inclined on both sides. The length of the bottom edge of the fastening block is adapted to the length of the top opening. The elastic fastening block can be inserted from the top opening or from the side opening.

[0011] In some embodiments, the end of the combined shoulder strap is provided with Velcro and fleece fabric, and the end of the combined shoulder strap passes through the pull loop and is bonded to the fleece fabric via the Velcro. The Velcro and fleece fabric at the end of the combined shoulder strap are used to fix the length of the shoulder strap and make the length of the shoulder strap adjustable.

[0012] In some embodiments, the back of the detector body has two recessed hanging slots. Limiting plates extend from both sides of the hanging slots towards the center, with a gap between the two limiting plates. The recessed hanging slots facilitate the insertion of hooks for wall mounting, thereby fixing the detector in place on the wall. The extended limiting plates act as a blocking element.

[0013] In some embodiments, the bottom of the suspension groove is inclined. The inclined bottom of the suspension groove serves as a guide, making it easier for the hook to be inserted and removed, enabling quick suspension and retrieval of the detector.

[0014] In some embodiments, a suspension bracket is further included, comprising two hooks and a support rod connected between the two hooks. An adhesive plate extends upward from one side of each hook, and an adhesive sheet is provided on the adhesive plate. The suspension groove is slidably connected to the hook. The suspension bracket is adhered to a wall or other flat surface by the adhesive sheet on its back side, and is used to detect air quality in a fixed area. The hooks serve to fix the detector, and the support bracket connects the two hooks, making them a single unit.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are:

[0016] This invention utilizes a detachable extension hose screwed onto the air pump inlet to extract gas from distant or enclosed spaces, expanding the application scenarios of the oxygen content detector. The detector also features a detachable shoulder strap, allowing it to be held in hand or fixed to the arm for easy portability. A hanging slot on the back of the detector, combined with a wall-mounted bracket, allows it to be hung on a wall for detecting air quality within a fixed area, while also facilitating easy access to readings.
