[0029] Reference Figures 1 to 3 , the utility model embodiment is a gas detection dual-mode intercom explosion-proof handheld device, including a shell 1, the shell 1 includes a front cover 11 and a rear cover 12, the front cover 11 is fixedly connected to the rear cover 12, and the front cover 11 and the rear cover 12 jointly form a mounting cavity 13;

[0030] It also includes an adjustment component and a detection component, the detection component is fixedly connected to the housing 1, the detection component includes a probe 31 and a probe cover 32, the probe 31 is arranged in the probe cover 32, and the probe cover 32 is provided with a detection hole 321;

[0031] The adjustment assembly is arranged in the installation cavity 13, and the adjustment assembly includes an adjustment column 2 and a lifting member 5. The adjustment column 2 includes a first plane and a second plane with different heights, and the first plane and the second plane are connected by an arc surface. One end of the lifting member 5 is rollingly connected to the adjustment column 2, and the other end of the lifting member 5 is connected to a shielding cover 322.

[0032] The adjustment component also includes a pressing piece. When the pressing piece is not pressed, one end of the lifting piece 5 abuts against the first plane, so that the shielding cover 322 does not block the detection hole 321; when the pressing piece is pressed and one end of the lifting piece 5 abuts against the arc surface, the shielding cover 322 at least partially blocks the detection hole 321; when the pressing piece is pressed and one end of the lifting piece 5 abuts against the second plane, the shielding cover 322 completely blocks the detection hole 321.

[0033] Based on the above, the housing 1 includes a front cover 11 and a rear cover 12, which are fixedly connected to form a closed installation cavity 13. Such a setting effectively prevents external explosive gas from entering the interior of the device, thereby improving the explosion-proof performance and safety. It ensures that the internal components of the device are not damaged by external factors, maintains the structural stability and reliability of the device, effectively blocks the potential safety threats caused by external factors to the device in a potentially dangerous environment, and ensures that the device can complete its work tasks in a safe operating state.

[0034] The handheld device includes a detection component, which includes a probe 31 and a probe cover 32. The probe cover 32 is fixedly connected to the back cover 12. One end of the probe 31 is suspended in the probe cover 32, and the other end is connected to the shell 1. The probe cover 32 is cylindrical and has a detection hole 321 in its circumferential direction. The detection hole 321 and the probe 31 are at the same height. This design enables the detection component to detect gas samples more accurately and avoid detection errors caused by improper positioning of the probe 31.

[0035] The handheld device also includes an adjustment component and a clamping member, one end of the clamping member is connected to the adjustment column 2, and the other end extends to the outer wall of the shell 1 and is convexly arranged on the shell 1. The adjustment column 2 includes a first plane and a second plane, wherein the first plane and the second plane are connected by an arc surface. When the clamping member is released, the adjustment column 2 moves along the first direction. When one end of the lifting member 5 is located on the first plane, the shielding cover 322 abutting against the inner wall of the probe cover 32 has an upper side wall flush with the lower inner wall of the detection hole 321, that is, the detection hole 321 is completely connected to the external environment, and the handheld device performs gas detection; when the clamping member is pressed, the adjustment column 2 continues to move in the first direction, and when the lifting member 5 gradually moves to the second plane, the detection hole 321 is gradually blocked by the shielding cover 322, and the size of the detection hole 321 is gradually reduced. The handheld device adjusts the size of the detection hole 321 to continuously detect the gas; when the lifting member 5 is located on the second plane, the detection hole 321 is completely blocked by the shielding cover 322, and the handheld device completes the gas detection.

[0036] In summary, through the design of the adjustment column 2 and the clamping member, the adjustment assembly includes the adjustment column 2, the lifting member 5, the shielding cover 322 and the clamping member. Through the precise design and mutual cooperation of these components, the switch function of the detection hole 321 is realized. The adjustment column 2 has a first plane and a second plane of different heights, which are connected by an arc surface so that the lifting member 5 can be flexibly moved between different heights. The shielding cover 322 is arranged at the other end of the lifting member 5, and the position of the shielding cover 322 can be controlled according to the height change of the lifting member 5, thereby realizing the adjustment of the shielding degree of the detection hole 321. The pressing state of the clamping member allows the shielding cover 322 to be fixed in different positions, thereby adjusting the opening size of the detection hole 321. This design allows the handheld device to flexibly adjust the opening size of the detection hole 321 according to specific detection requirements and environmental conditions. When a larger gas flux or a faster detection response is required, the detection hole 321 can be fully opened; when the gas flux needs to be reduced or the detection accuracy needs to be improved, the detection hole 321 can be partially or completely closed to meet the actual application requirements in different scenarios; the user can conveniently control the opening and closing size of the detection hole 321, thereby flexibly adjusting the sensitivity of gas detection. During the adjustment process, the shielding cover 322 in the probe cover 32 will cover or expose the detection hole 321 as the lifting member 5 moves between the first plane and the second plane, thereby achieving precise adjustment of gas detection. When the detection hole 321 is completely covered by the shielding cover 322, external gas is effectively prevented from entering the interior of the device, reducing the risk of accidents in dangerous environments. This setting can ensure that the internal environment remains closed and stable when the handheld device performs gas detection. At the same time, the design of the clamping piece enables the user to quickly adjust the size of the detection hole 321. The opening and closing of the detection hole 321 can be completed by simply pressing or releasing the clamping piece, which improves the convenience and response speed of operation. It is suitable for a variety of industrial occasions, including oil and gas exploration, chemical plants, mining areas and other environments where explosive gases may exist.

[0037] The adjustment assembly further includes a slide table 21 , and the adjustment column 2 is provided with a slide rail, and the slide rail is slidably connected to the slide table 21 .

[0038] By connecting the slide 21 to the slide rail, the adjustment column 2 can move smoothly along the slide rail to ensure the stability of the adjustment process. The connection design between the slide 21 and the slide rail can enable the adjustment column 2 to achieve slight movement and adjustment during the adjustment process. This fine adjustment capability allows the user to more accurately control the size of the detection hole 321 to meet the needs of accurate monitoring of gas concentration.

[0039] The pressing member includes an elastic member 41 and a connecting member 42 . The connecting member 42 is provided in two groups. Both ends of the elastic member 41 are connected to the connecting member 42 respectively.

[0040] The connecting member 42 includes a first connecting column and a second connecting column. One end of the first connecting column is connected to the adjusting column 2, and the other end is connected to the elastic member 41. One end of the second connecting column is connected to the elastic member 41, and the other end is connected to a pressing member. The pressing member is protruding from the surface of the shell 1. When gas detection is not required, the pressing member is pressed tightly, and the surface of the pressing member is flush with the outer wall of the shell 1.

[0041] The lifting member 5 includes a roller 51 and a lifting portion 52, one end of the lifting portion 52 is connected to the roller 51, and the other end of the lifting portion 52 is connected to the shielding cover 322. When the roller 51 is located in the first plane, the detection hole 321 is connected to the outside world. When the roller 51 is located in the second plane, the shielding cover 322 blocks the detection hole 321.

[0042] Through the design of the roller 51 and the lifting part 52, the size of the detection hole 321 can be precisely adjusted. The roller 51 moves between the first plane and the second plane. Depending on its position, the detection hole 321 can be completely connected to the outside world or blocked, thereby achieving precise control of gas detection. When the roller 51 is located in the second plane, the shielding cover 322 blocks the detection hole 321, effectively preventing external gas from entering the interior of the device, thereby improving the protection and safety of the device. The movement of the shielding cover 322 and the change in the position of the roller 51 ensure the effective isolation of the gas sample.

[0043] The roller 51 continuously moves between the first plane and the second plane, so as to realize continuous monitoring and continuous response to the detection hole 321. This setting enables the device to continuously monitor and adjust the target gas, ensuring the continuity and accuracy of gas detection.

[0044] The probe cover 32 and the housing 1 together form a detection cavity. A sensor 8 is disposed in the detection cavity. The sensor 8 is connected to the probe 31 .

[0045] The probe 31 completes gas detection in the detection cavity and uses the detection cavity to isolate the sensor 8 from the external environment, thereby protecting the sensor 8 and improving the safety, accuracy and maintenance convenience of the explosion-proof handheld device.

[0046] The rear cover 12 is provided with a clamping member 6 .

[0047] The arrangement of the clamping member 6 can provide additional fixation and support on the rear cover 12, which helps to stabilize the position of the rear cover 12 on the housing 1. This design can increase the stability of the rear cover 12, prevent the rear cover 12 from loosening or falling off under interference or impact, improve the explosion-proof performance, stability and maintainability of the equipment, and protect the detection components.

[0048] The front cover 11 and the rear cover 12 are both made of explosion-proof lightweight metal.

[0049] The explosion-proof light metal material has good explosion-proof performance and can effectively reduce the risk of explosion or fire of the equipment in a dangerous environment. When facing a potential explosive gas or dust environment, the front cover 11 and the rear cover 12 made of explosion-proof metal can effectively protect the safety of the equipment and operators.

[0050] Lightweight metal materials are lighter than ordinary metal materials, which can reduce the overall weight of the equipment and improve the convenience of carrying and operation.
