Description

Technical Field

[0001] This utility model relates to the field of gas detection device technology, and more specifically, to a portable gas detection device. Background Technology

[0002] A gas detector is an instrument used to detect the concentration of leaked gases. It mainly uses gas sensors to detect the types of gases present in the environment. Gas detectors include portable gas detectors and stationary gas detectors. Portable gas detectors are widely used in various places where mobile gas detection is required due to their small size and portability.

[0003] For example, patent CN213148854U discloses a portable gas detection device. A protective device can be used to seal the top of the first or second air inlet to prevent external dust and other foreign objects from clogging the air inlet when it is in standby mode, thus ensuring normal use later. However, in the application of existing gas detection devices, the protection measures for the display screen are relatively weak. Currently, only a simple film is used to protect the display screen, and there is a lack of a dedicated protective structure. In actual use scenarios, workers often need to carry the device to work, and the device is bound to fall during the process. At this time, the display screen is very easy to be damaged by impact due to the lack of effective cushioning protection, which will cause the detection data to be unable to be read normally and affect the work.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] like Figures 1-3 As shown, a portable gas detection device includes a gas monitor 1. A rotating shaft 6 is fixedly connected to the outer wall of the gas monitor 1. A torsion spring 22 is sleeved on the outer wall of the rotating shaft 6. A bearing 7 is fixedly connected to the outer wall of the rotating shaft 6. A turntable 8 is fixedly connected to the outer wall of the bearing 7. One end of the torsion spring 22 is fixedly connected to the gas monitor 1, and the other end is fixedly connected to the turntable 8. A protective cover 4 is fixedly connected to the outer wall of the turntable 8. The protective cover 4 is used to cover the display screen on the gas monitor 1. A positioning component is installed on the outer wall of the gas monitor 1, and a release component is installed on the top of the rotating shaft 6. The design of the torsion spring 22 allows the protective cover to automatically cover the display screen after the positioning is released.

[0023] like Figure 1 and Figure 2 As shown, a baffle 3 is fixedly connected to the outer wall of the gas monitor 1. The baffle 3 is used to block the protective cover 4 after it is released. The baffle 3 also blocks the protective cover when it is reset, limiting the maximum rotation angle of the protective cover.

[0024] like Figure 3As shown, the positioning assembly includes a guide block 14, with a guide groove 15 at its top. A locking post 18 is slidably connected to the inner wall of the guide groove 15, and the locking post 18 is slidably connected to the outer wall of the turntable 8. A sliding rod 16 is slidably connected to the inner wall of the guide block 14, with its end passing through and slidably connected to the guide block 14. A second return spring 17 is sleeved on the outer wall of the sliding rod 16, and an end block 20 is fixedly connected to the end of the sliding rod 16. The end of the sliding rod 16 is fixedly connected to the locking post 18. A slot 21 is formed on the outer wall of the turntable 8, and the locking post 18 engages with the slot 21. One end of the second return spring 17 is fixedly connected to the end block 20, and the other end of the second return spring 17 is fixedly connected to the guide block 14. The engagement of the locking post 18 with the slot 21 provides positioning for the protective cover 4. The engagement of the guide block 14 and the sliding rod 16 restricts the locking post 18 to slide only in a straight line, ensuring that the locking post 18 can be embedded in the slot 21 each time.

[0025] like Figure 4 As shown, the release assembly includes a pressure cap 9, a groove 10 at the bottom of the pressure cap 9, a first return spring 11 inside the groove 10, a movable hole 12 on the outer wall of the rotating shaft 6, a sliding plate 13 slidably connected inside the movable hole 12, the two ends of the sliding plate 13 being fixedly connected to the inner wall of the groove 10 respectively, one end of the first return spring 11 being fixedly connected to the pressure cap 9, and the other end of the first return spring 11 being fixedly connected to the rotating shaft 6.

[0026] The bottom of the pressure cap 9 has a conical structure, and the top of the retaining post 18 is fixedly connected to a semi-circular arc end 19. This design can reduce the friction between the pressure cap 9 and the retaining post 18. The top of the protective cover 4 protrudes upward to form a raised edge 5. A gas nozzle 2 is installed on the outer wall of the gas monitor 1.

[0027] When in use, the protruding edge 5 is moved to rotate the protective cover 4, which in turn rotates the turntable 8, causing the protective cover 4 to move away from the display screen of the gas monitor 1. When the turntable 8 rotates, when the slot 21 on its surface rotates to the position of the locking post 18, the locking post 18 is locked into the slot 21 under the elastic force of the second return spring 17, thus limiting and fixing the turntable 8.

[0028] Press down on the cap 9 to compress the first reset spring 11, and at the same time drive the slide plate 13 to slide along the inner wall of the movable hole 12. The cap 9 squeezes the arc end 19, causing the locking post 18 to move out of the slot 21. At this time, under the torsion of the torsion spring 22, the protective cover 4 moves in the opposite direction to block the display screen, and at the same time the blocking post 3 blocks the protective cover 4.

[0029] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
