Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring device technology, specifically a portable oxygen monitoring device for coal mine safety management. Background Technology
[0002] In the underground working environment of coal mines, oxygen concentration is a core indicator to ensure the safety of workers. Portable oxygen monitoring devices are essential safety equipment, and their portability directly affects work efficiency and safety. To meet basic carrying requirements, existing portable oxygen monitoring devices usually have a buckle structure on the device body so that workers can hang the device on their waist.
[0003] However, the working environment in coal mines is complex, and workers need to frequently move between tunnels and equipment. Relying solely on waist buckles for carrying devices has obvious limitations, offering only a single carrying function and failing to meet the carrying needs of different working scenarios. For example, when climbing equipment or bending over to work, the device suspended from the waist is prone to colliding or getting caught on surrounding objects. When workers need to temporarily move the device or use a handheld device for fixed-point testing, there is a lack of convenient hand-held structures. Therefore, it is necessary to design a portable oxygen monitoring device for coal mine safety management to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a portable oxygen monitoring device for coal mine safety management, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable oxygen monitoring device for coal mine safety management, including a monitor, a slider connected to the back of the monitor for limiting sliding, the slider being able to be locked in position by a first locking component, a pull ring being fixedly installed at one end of the slider, and a buckle being fixedly installed at the other end.
[0006] Preferably, two sets of slide blocks are symmetrically fixedly installed on the back of the monitor, and the two sets of slide blocks enclose each other to form a T-shaped slide for the slider to slide.
[0007] Preferably, the first locking component includes a retainer integrally formed on both sides of the slider. A first spring is fixedly installed in the inner cavity of the retainer. A retaining block is fixedly connected to the free end of the first spring. The retaining block can be adapted to be inserted into a corresponding first slot on the slider to achieve positioning and locking of the slider after sliding.
[0008] Preferably, a second locking component is provided at the end of the buckle away from the slider. The second locking component includes a limiting frame fixedly installed at that end of the buckle. The limiting frame can be adapted to be inserted into the second slot correspondingly opened on the back of the monitor. A second spring is sleeved on the outside of the rod of the limiting frame. The second spring is used to provide an elastic locking force after the limiting frame is inserted into the second slot.
[0009] Preferably, the upper front end of the monitor is integrated with an air intake module, and the lower front end of the monitor is integrated with a display module. Both the air intake module and the display module are electrically connected to the detection motherboard inside the monitor.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention enables quick switching between two carrying methods—buckle suspension and pull ring handle—through the sliding switch of a slider. It is suitable for various scenarios such as walking in underground coal mine roadways, climbing equipment, bending over to work, and fixed-point inspection. The T-shaped slide's limiting design, combined with the locking structure of the first locking component, ensures that there is no loosening or displacement after the slider is switched positions. Pressing the locking block unlocks the sliding mechanism, making the operation simple and meeting the needs of underground workers for quick operation. The pull ring and buckle are integrated into the same slider, eliminating the need for additional accessories. This maintains the device's portability while expanding its functionality, balancing work efficiency and safety.
[0011] The second locking component of this utility model works in conjunction with the first locking component to achieve dual fixation of the slider at two functional positions, solving the loosening problem that may occur with single locking. It is suitable for complex working environments with bumps and collisions underground. The secondary locking at the buckle position prevents the buckle from coming loose due to large movements of the operator when the device is suspended at the waist, preventing the device from falling, being damaged or lost. The dual locking at the pull ring position ensures that the slider will not slide when handheld for fixed-point testing, preventing the pull ring from accidentally retracting and affecting operation, while also preventing the device from slipping out of the hand.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example 1 Please refer to Figure 1-5 As shown, this utility model provides a portable oxygen monitoring device for coal mine safety management, including a monitor 11. A slider 12 is slidably connected to the back of the monitor 11. The slider 12 can be locked in position by a first locking component. A pull ring 13 is fixedly installed at one end of the slider 12, and a buckle 14 is fixedly installed at the other end. Two sets of slide seats 15 are symmetrically fixedly installed on the back of the monitor 11. The two sets of slide seats 15 enclose a T-shaped slide track 16 for the slider 12 to slide. The first locking component includes a card seat 17 integrally formed on both sides of the slider 12. A first spring 18 is fixedly installed in the inner cavity of the card seat 17. A card block 19 is fixedly connected to the free end of the first spring 18. The card block 19 can be inserted into the corresponding first card slot 21 on the slide seat 15 to achieve the positioning and locking of the slider 12 after sliding.
[0016] The back of the monitor 11 is surrounded by two sets of symmetrically fixed slide blocks 15 to form a T-shaped slide track 16, which provides a limiting sliding trajectory for the slider 12 to ensure that the slider 12 does not deviate or fall off during the sliding process. The two ends of the slider 12 are integrated with pull rings 13 and buckles 14 respectively. The operator can push the slider 12 to move along the T-shaped slide track 16 according to the usage scenario and switch the function. After the slider 12 moves to the target position, the first spring 18 in the two side brackets 17 releases elastic potential energy and pushes the block 19 to embed into the first slot 21 opened in the corresponding slide block 15 to complete the position locking of the slider 12 and ensure the structural stability during use.
[0017] The sliding switch of slider 12 enables quick switching between two carrying methods: suspension with buckle 14 and hand-carrying with pull ring 13. This adapts to various scenarios such as walking in underground coal mine roadways, climbing equipment, bending over, and fixed-point inspection. The limiting design of T-shaped slide 16, combined with the snap-fit structure of the first locking component, ensures that slider 12 does not loosen or shift after switching positions. Pressing the latch 19 unlocks the sliding mechanism. The operation is simple and meets the needs of underground workers for quick operation. Pull ring 13 and buckle 14 are integrated into the same slider 12, eliminating the need for additional accessories. This maintains the portability of the device while expanding its functionality, balancing work efficiency and safety.
[0018] Specifically, a second locking component is provided at the end of the buckle 14 away from the slider 12. The second locking component includes a limiting frame 22 fixedly installed at that end of the buckle 14. The limiting frame 22 can be adapted to be inserted into the second slot 23 correspondingly opened on the back of the monitor 11. A second spring 24 is sleeved on the outside of the rod of the limiting frame 22. The second spring 24 is used to provide an elastic locking force after the limiting frame 22 is inserted into the second slot 23.
[0019] When the slider 12 is pushed to put the buckle 14 in the suspension position, the limit frame 22 is inserted into one of the second slots 23. The second spring 24 is compressed and generates an elastic force, which tightly locks the limit frame 22 in the slot, thereby achieving secondary fixation of the buckle 14 and preventing the buckle 14 from loosening and falling off during the suspension process.
[0020] When the slider 12 is pushed to put the pull ring 13 in the hand-carrying position, the limit frame 22 is inserted into another set of second slots 23. The elastic locking force of the second spring 24, together with the locking block 19 of the first locking component and the locking of the first slot 21, forms a double lock on the slider 12 to prevent the slider 12 from accidentally sliding during hand-carrying operation.
[0021] The second locking component works in conjunction with the first locking component to achieve dual fixation of the slider 12 at two functional positions, solving the loosening problem that may occur with single locking, adapting to the complex working environment of bumps and collisions underground. The secondary locking at the buckle 14 position prevents the buckle 14 from coming loose due to large movements of the operator when the device is suspended at the waist, preventing the device from falling, being damaged or lost. The dual locking at the pull ring 13 position ensures that the slider 12 will not slide when handheld for fixed-point testing, preventing the pull ring 13 from accidentally retracting and affecting the operation, while also preventing the device from slipping out of the hand.
[0022] The monitor 11 has an air intake module 25 integrated on the upper front and a display module 26 integrated on the lower front. Both the air intake module 25 and the display module 26 are electrically connected to the detection motherboard inside the monitor 11.
[0023] During underground operations, outside air enters the monitor 11 through the air intake module 25. The mainboard collects and analyzes the oxygen concentration in the air sample and transmits the calculated oxygen concentration data to the display module 26, which displays the current ambient oxygen concentration value in real time for the operators to read intuitively.
[0024] The integrated layout of the air intake module 25 and the display module 26 realizes an integrated process of "sampling-analysis-display" of oxygen concentration, eliminating the need for additional external equipment, simplifying the detection operation steps, and adapting to the needs of rapid downhole detection. The detection and display functions are integrated with the device body, without occupying additional external space. Combined with the portable structure design of the slider 12, the portability of the device is further guaranteed, avoiding an increase in size due to functional expansion.
[0025] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
