[0002] In the industrial field, especially in high-risk scenarios such as oil refining, chemical processing, mining, and tunnel construction, intercom equipment is an essential tool for on-site communication; the role of intercom equipment is to enable workers to communicate in real time, coordinate operations, improve work efficiency, and respond quickly in emergency situations. However, in addition to the communication function, the above-mentioned high-risk scenarios also have safety hazards such as gas leakage. Therefore, workers often need to carry gas detection devices to regularly detect the content of harmful gases in high-risk scenarios.

[0003] For the above solution, the extra gas detection device will take up extra pocket space of the staff, and the portability is insufficient. At the same time, the gas detection device generally does not have explosion-proof performance. If electric sparks are generated inside the gas detection device, it is easy to ignite the flammable gas in the environment, which poses a safety hazard and has poor explosion-proof performance. It can be seen that the equipment commonly used in high-risk scenarios currently has technical problems such as insufficient portability and poor explosion-proof performance. Utility Model Content

[0033] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] like Figures 1 to 4 As shown, Figure 1 The overall structural diagram of the portable gas detection dual-mode intercom explosion-proof terminal provided by the embodiment of the utility model is as follows: Figure 2 A schematic diagram of the top view of the portable gas detection dual-mode intercom explosion-proof terminal provided in an embodiment of the utility model, Figure 3 for Figure 2 Schematic diagram of the cross-section structure along AA, Figure 4 A schematic diagram of the partial explosion structure of the portable gas detection dual-mode intercom explosion-proof terminal provided in an embodiment of the utility model.

[0037] The portable gas detection dual-mode intercom explosion-proof terminal provided in this embodiment is used in high-risk scenarios such as oil refining, chemical processing, mining, tunnel construction, etc., to provide communication functions and gas detection functions for workers to provide safety protection. At the same time, in this embodiment, the structure of the portable gas detection dual-mode intercom explosion-proof terminal is improved to effectively improve its portability and explosion-proofness.

[0038] like Figures 1 to 4 As shown, the portable gas detection dual-mode intercom explosion-proof terminal provided in this embodiment includes a detection terminal body 100, an intercom module 200 and a detection component 300; the detection terminal body 100 is configured with an inner cavity 101, and a detection hole 102 is opened on the cavity wall of the inner cavity 101; the intercom module 200 is installed on the detection terminal body 100, and the intercom module 200 refers to a structure that allows staff to conduct wireless conversations with other personnel. Its specific structure is well known in the art and will not be specifically expanded and introduced; the detection component 300 is penetrated by the detection hole 102, and is configured with a detection channel 301, and the detection component 300 is slidably connected with the detection hole 102 between the detection position and the sealing position. Among them, when the detection component 300 is located at the detection position, the entrance of the detection channel 301 is exposed to the detection terminal body 100, and when the detection component 300 is located at the sealing position, the entrance of the detection channel 301 is sealed by the hole wall of the detection hole 102.

[0039] Specifically, the portable gas detection dual-mode intercom explosion-proof terminal in this embodiment can realize the intercom function through the intercom module 200. At the same time, when it is necessary to detect the gas content in the environment, the detection component 300 is located at the detection position, so that the sensor (not shown) in the detection component 300 obtains the gas sample from the environment through the detection channel 301 and monitors it. It should be noted that after the detection is completed, the detection component 300 is returned to the sealing position, so that the entrance of the detection channel 301 is sealed by the hole wall of the detection hole 102. On the one hand, most of the detection component 300 is not exposed to the detection terminal body 100, making the structure more compact and highly portable. On the other hand, it can separate the detection component 300 from the environment in the non-detection state to prevent the sparks accidentally generated inside from invading the detection environment, thereby improving the explosion-proof performance. It can be seen that the portable gas detection dual-mode intercom explosion-proof terminal in this solution has the intercom function and the gas detection function, and has the advantages of high portability and high explosion-proof performance.

[0040] In addition, the antenna 800 is detachably mounted on the detection terminal body 100, so that the portable gas detection dual-mode intercom explosion-proof terminal can be placed in a more compact form (split type) in the pocket or storage space of the staff.

[0041] Furthermore, a detection button 400 is also movably connected to the detection terminal body 100, and a trigger component 500 and a reset component are arranged in the inner cavity 101; the input end of the trigger component 500 is connected to the detection button 400, and the output end of the trigger component 500 is connected to the detection component 300, and the trigger component 500 is used to push the detection component 300 to move to the detection position when pressed; the reset component is used to move the detection component 300 to the sealing position when it is not subjected to external force. It can be understood that when it is necessary to detect the gas content, the staff presses the detection button 400 to move the detection component 300 to the detection position; when the staff releases it, the reset component moves the detection component 300 to the sealing position, so that the detection component 300 can measure the gas content, which includes but is not limited to carbon monoxide, methane, etc., according to different working scenarios.

[0042] Furthermore, if Figure 3 and Figure 4 As shown, the trigger assembly 500 includes a first wedge block 510 connected to the detection button 400 and a second wedge block 520 connected to the detection assembly 300; the first wedge block 510 abuts against the second wedge block 520, and the abutting surfaces of the first wedge block 510 and the second wedge block 520 are inclined relative to the sliding direction of the detection assembly 300. Therefore, when the detection button 400 is pressed, the first wedge block 510 pushes the second wedge block 520, so that the second wedge block 520 drives the detection assembly 300 to move to the detection position.

[0043] Furthermore, the detection assembly 300 includes a detection fixed portion 310 installed in the inner cavity 101 and a detection movable portion 320 slidably connected to the detection fixed portion 310; the detection channel 301 is opened on the detection movable portion 320, and the detection movable portion 320 is configured with a detection position and a sealing position, and the detection movable portion 320 is fixedly connected to the second wedge block 520. Therefore, when the detection button 400 is pressed, the first wedge block 510 pushes the second wedge block 520, so that the second wedge block 520 drives the detection movable portion 320 to move to the detection position.

[0044] Furthermore, the detection fixed portion 310 is provided with a detection sealed cavity 311, in which a sensor (not shown) is arranged. The type of the sensor is not limited and is well known to those skilled in the art, so it will not be elaborated in detail. It can be changed according to the type of gas to be detected, and a sliding hole 312 is provided on the cavity wall of the detection sealed cavity 311; the detection movable portion 320 includes a first sliding tube 321 through which the sliding hole 312 is passed and a second sliding tube 322 through which the detection hole 102 is passed, and an air inlet hole 323 is provided on the tube wall of the second sliding tube 322, and the air inlet hole 323, the second sliding tube 322 and the first sliding tube 321 are connected in sequence to form a detection channel 301.

[0045] Furthermore, a detection trigger switch 700 is also installed in the detection sealed cavity 311, and the detection trigger switch 700 is used to start the sensor when it is pressed by the first sliding tube 321. It can be understood that when the detection movable part 320 is located at the detection position, the gas in the environment can enter the detection sealed cavity 311 through the detection channel 301, and the sensor and the corresponding circuit structure do not work at this time; when the detection movable part 320 is driven to the sealing position by the compression spring 600, the first sliding tube 321 will trigger the detection trigger switch 700 under the action of the compression spring 600, thereby starting the sensor to detect the gas in the detection sealed cavity 311. It can be understood that at this time, the environment and the detection sealed cavity 311 have been separated by the hole wall of the detection hole 102, which can prevent the sparks accidentally generated inside from invading the detection environment, further improving the explosion-proof performance.

[0046] On the basis of the above embodiment, a guiding inclined surface 331 is formed at one end of the second sliding tube 322 facing the detection fixing portion 310 , and a guiding groove 332 is formed at a position of the hole edge of the sliding hole 312 corresponding to the guiding inclined surface 331 .

[0047] On the basis of the above-mentioned embodiment, the reset assembly includes a compression spring 600 installed between the second wedge block 520 and the detection fixing portion 310 , and the compression spring 600 abuts against the second wedge block 520 and the detection fixing portion 310 , respectively.

[0048] In summary, the portable gas detection dual-mode intercom explosion-proof terminal in this embodiment has intercom function and gas detection function, and has the advantages of high portability and high explosion-proofness.

[0049] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
