[0029] On the one hand, the present invention achieves the purpose of adopting a non-cooled detector in the infrared imager, eliminating the cooling module of the cooled detector, greatly reducing the volume and weight of the infrared imager, and at the same time reducing the use cost. It solves the problems of large volume, heavy weight, and high price of the infrared imager for gas detection in the related art. And after adopting the non-cooled detector, there is no need to cool down during startup, making it more convenient to use.

[0030] On the other hand, in this embodiment, a handle 14 is provided on the housing 13 of the infrared imager, and the user can hold the handle 14 for use. And when the infrared imager is in a lower position, the touch control screen 15 that can be flipped open can provide a suitable viewing angle for the user. And since the handle 14 is a detachable structure, the weight of the imager is further reduced after removal. At the same time, for the convenience of use after removal, a wrist strap 16 is also provided on the side of the housing 13 in this embodiment. After configuring the wrist strap 16, it can prevent the user's fingers from always tightly holding the body of the imager, making it more labor-saving to use.

[0031] Further, a flash lamp 18, an indicating laser lamp 19 and a visible light camera 20 are also provided at the front end of the housing 13. The flash lamp 18, the indicating laser lamp 19 and the visible light camera 20 are all arranged on the side of the infrared lens 21. A flash lamp key, an indicating laser lamp key and a visible light switching key are also provided on the housing 13. The flash lamp key controls the flash lamp 18 through a control module, the indicating laser lamp key controls the indicating laser lamp 19 through a control module, and the visible light switching key controls the visible light camera 20 through a control module.

[0032] Specifically, in this embodiment, the flash lamp 18 can be used to supplement light for the visible light camera 20 to take pictures in low-light environments such as at night, and it is also convenient for human eyes to observe. The indicating laser lamp 19 can be used to mark the position of gas leakage when cooperating with the visible light camera 20 to take pictures. The visible light camera 20 can take pictures or record videos to record the information of gas leakage. In one implementation manner, the flash lamp 18, the indicating laser lamp 19 and the visible light camera 20 are arranged in sequence from top to bottom, with a compact space, small and convenient. In addition, in one implementation manner, the housing 13 includes a main housing and an armrest housing 17. Components such as a non-cooled detector are installed in the main housing, and the armrest housing 17 is fixed on the right side of the main housing for installing the flash lamp 18, the indicating laser lamp 19, the visible light camera 20, the flash lamp 18 key, the indicating laser lamp 19 key and the visible light switching key, etc., which is convenient for operation. The armrest housing 17 can be made of plastic material, and the surface is sprayed with rubber paint, with a soft texture and excellent hand feeling, avoiding the stiffness of metal materials.

[0033] As Figure 1 shown, it also includes a data storage module, an operation knob 24, a power switch, a buzzer 23 and a debugging interface module; The control module includes a main control module and a sub-control module that are electrically connected. The main control module is electrically connected to the photoelectric conversion module; The sub-control module is electrically connected to the visible light camera 20, the visible light switching key, the flash lamp 18, the flash lamp 18 key, the battery module 33, the power switch, the buzzer 23 and the debugging interface module; The main control module is electrically connected to the touch control screen 15, the data storage module and the operation knob 24.

[0034] Specifically, in this embodiment, the buzzer 23 and the power switch can be installed on the armrest housing 17.

The wrist strap 16 can also be set on the side of the armrest housing 17.

[0035] The operating knob 24 is arranged on the right side of the outer shell 13, specifically on the right side of the main shell. Some control operations can be performed through the operating knob 24. In one embodiment, rotating the operating knob 24 can adjust the options on the touch control screen 15, and pressing the operating knob 24 can select the options, which is more convenient for operators wearing gloves.

[0036] In addition, for further convenience of use, the adjustment interface module in the imager in this embodiment includes a Type-C debugging port 29 arranged on the rear side of the housing 13. In addition, the rear side of the housing 13 is also provided with an HDMI port 31, a TF card connector 32, and a battery charging port 30.

[0037] To facilitate adjusting the angle of the touch control screen 15, the first end of the touch control screen 15 is hinged to the housing 13 via a shaft in this embodiment. Specifically, the shaft can be a bidirectional shaft, so that the touch control screen 15 can also rotate in another direction after being rotated open relative to the housing 13, making the angle adjustment of the touch control screen 15 more flexible.

[0038] To facilitate locking the touch control screen 15, in this embodiment, a first snap-in portion 159 is provided at the second end of the touch control screen 15, and a second snap-in portion 28 corresponding to the first snap-in portion 159 is provided on the housing 13, and the first snap-in portion 159 is snap-connected with the second snap-in portion 28.

[0039] In one embodiment, the first snap-fit ​​portion 159 includes a ball plunger, a portion of which extends out of the second end of the touch control screen 15, and the second snap-fit ​​portion 28 includes a card plate fixed on the housing 13, and a card hole 280 is provided on the card plate to be snap-connected to the ball plunger.

[0040] When the touch control screen 15 rotates to fit the side of the housing 13, the ball plunger is inserted into the clamping hole 280 to fix the touch control screen 15. When it is necessary to open the touch control screen 15, the ball plunger can be pushed outward to disengage the clamping hole 280.

[0041] To protect the screen of the touch control screen 15, Figure 4 As shown, in this embodiment, a silicone pad 281 is provided on one side of the housing 13 and the touch control screen 15 . The silicone pad 281 is close to the second buckle portion 28 , and the touch control screen 15 can be rotated to fit with the silicone pad 281 .

[0042] The touch screen in the related art has the problems of being time-consuming and labor-intensive to assemble, difficult to disassemble, poor heat dissipation, and being easily deformed when pressed at a position far from the support point.

[0043] To solve this technical problem, Figure 15 As shown, the touch control screen 15 in this embodiment includes: Front shell 150; Screen frame glue 151, and the screen frame glue 151 is adhesively fixed to the back surface of the front shell 150; Screen assembly 152, and the edge of the screen assembly 152 is adhesively fixed to the back surface of the screen frame glue 151; Vapor chamber 153, and the vapor chamber 153 is attached to the back surface of the screen assembly 152; Pressing foam 154, and the pressing foam 154 is pressed and attached to the back surface of the vapor chamber 153, and heat conduction holes 1540 are provided on the pressing foam 154; Thermal pad 155, and the thermal pad 155 is disposed in the heat conduction holes 1540, and the thermal pad 155 is attached to the back surface of the vapor chamber 153; Bracket 156, and the bracket 156 is attached to the back surface of the pressing foam 154 and fixedly connected to the front shell 150, and the back surface of the thermal pad 155 is attached to the surface of the bracket 156; Rear shell 158, and the rear shell 158 is fixedly connected to the front shell 150.

[0044] In this embodiment, during assembly, first, the screen frame glue 151 is adhesively fixed to the back surface of the front shell 150. The screen frame glue 151 is of a frame structure and has a narrow width, and the screen frame glue 151 can be double-sided tape. Then, the vapor chamber 153 is fixed to the back surface of the screen assembly 152. The vapor chamber 153 can be fixed to the screen assembly 152 by adhesion, and then the front end of the screen assembly 152 is adhesively bonded to the back surface of the screen frame glue 151. In one embodiment of the vapor chamber 153, the vapor chamber 153 can be a graphite sheet. Next, the pressing foam 154 can be fixed to the front end of the bracket 156. The pressing foam 154 and the bracket 156 can be adhesively fixed. A thermal pad 155 is placed in the heat conduction holes 1540 of the pressing foam 154, and the thermal pad 155 can be adhesively fixed to the bracket 156. The thickness of the thermal pad 155 is close to the thickness of the pressing foam 154, so that the thermal pad 155 can be attached to the surface of the vapor chamber 153. Then, the bracket 156 is fixed to the front shell 150, and the two can be locked together by screws. Finally, the rear shell 158 is fixed to the front shell 150, and thus the assembly of the entire screen is completed.

[0045] On the one hand, in this embodiment, after the screen assembly 152 is bonded and fixed to the front shell 150 by the relatively narrow screen frame adhesive 151, it can not only play the role of fixing the screen assembly 152, but also play the role of waterproofing, dustproofing and anti-static. And when clicking on the screen, even if the screen is relatively thin and has low rigidity, the screen frame adhesive 151 can also pull the screen to prevent deformation and improve the feel when clicking. Moreover, since the screen frame adhesive 151 is used to bond and fix the screen assembly 152, during installation, only the screen frame adhesive 151 needs to be bonded to the front shell 150, and then the screen assembly 152 is bonded to the screen frame adhesive 151. The installation process is relatively simple and convenient. During disassembly, since the screen frame adhesive 151 is an independent component, the disassembly process is also relatively easy. On the other hand, after the pressing foam 154 is arranged on the back surface of the screen assembly 152, it can prevent deformation when pressing the screen, and can improve the pressing feel. At the same time, the pressing foam 154 can absorb part of the impact force when the screen assembly 152 is impacted, avoiding damage.

[0046] On yet another hand, after the heat spreader 153 is arranged on the back surface of the screen assembly 152, it can quickly and evenly disperse the heat generated by the screen assembly 152, and then transfer it to the bracket 156 through the thermal pad 155. The bracket 156 serves as both an installation support structure and a heat dissipation structure, improving the heat dissipation performance of the entire device.

[0047] On the basis of the above embodiment, the screen fixing structure in this embodiment further includes a screen adapter 157. The screen adapter 157 is fixedly arranged on the back surface of the bracket 156. A wire passing hole is arranged on the bracket 156. The control wire of the screen assembly 152 passes through the wire passing hole and is connected to the screen adapter 157. The screen adapter 157 is used for signal conversion and can be electrically connected to the control module.

[0048] During assembly, after the bracket 156 is fixedly connected to the front shell 150, the control wire of the screen assembly 152 is passed through the wire passing hole and extended to the back surface of the bracket 156, and then the screen adapter 157 is fixed to the back surface of the bracket 156. The control wire is connected to the screen adapter 157, and signal conversion is performed through the screen adapter 157. The screen adapter 157 and the bracket 156 can be fixedly connected by a plurality of screws.

[0049] In one implementation, an installation groove is arranged on the back surface of the front shell 150. The installation groove is arranged in a ring structure. The screen frame adhesive 151 is embedded in the installation groove, and a part of the screen frame adhesive 151 protrudes from the installation groove and is bonded to the screen assembly 152.

[0050] Specifically, in this embodiment, firstly, the installation groove can locate the position of the screen frame adhesive 151, facilitating the bonding and fixing of the screen frame adhesive 151 during the assembly process. Secondly, after a part of the screen frame adhesive 151 is accommodated by the installation groove, the gap between the front shell 150 and the screen assembly 152 caused by the thickness of the screen frame adhesive 151 is reduced, avoiding excessive gaps and improving the dust-proof ability and aesthetics.

[0051] Since the screen frame adhesive 151 will be deformed under pressure when the screen assembly 152 is bonded and fixed, in this embodiment, the width of the installation groove is greater than the width of the screen frame adhesive 151, thereby providing a certain deformation space for the screen frame adhesive 151.

[0052] Furthermore, the periphery of the heat-conducting pad 155 is closely attached to the periphery of the heat-conducting hole 1540, thus reasonably utilizing the space and enhancing the heat-conducting performance. To improve the heat dissipation effect, the bracket 156 is made of a metal material with good heat dissipation performance. Since the bracket 156 has a large area and is made of a metal material with good heat dissipation performance, it can greatly increase the heat dissipation performance of the entire module.

[0053] To further increase the connection stability and structural rigidity, in this embodiment, the rear shell 158 is snap-connected to the front shell 150. Fixed parts 1560 corresponding to the side walls of the front shell 150 are provided at the upper and lower ends of the bracket 156, and the side walls of the front shell 150, the fixed parts 1560, and the side walls of the rear shell 158 are locked by a plurality of fixing screws.

[0054] Specifically, in this embodiment, after the rear shell 158 is snap-connected to the front shell 150, it is convenient to position the connection between the rear shell 158 and the front shell 150 before locking with the fixing screws. The fixing screws can be connected to the peripheral side walls of the front shell 150 and the rear shell 158, as well as the upper and lower ends of the bracket 156. After the front shell 150, the bracket 156, and the rear shell 158 are locked together by the fixing screws, the rigidity of the bracket 156 is strengthened, and at the same time, the strength of the entire module is improved.

[0055] To facilitate the opening and closing of the battery compartment door 27, as Figures 6 to 14 shown, the battery compartment door 27 includes: A base 1, the base 1 is fixedly arranged at the rear side of the outer shell 13. An opening corresponding to the battery installation compartment is provided on the base 1, and a first clamping structure 100 is provided on the base 1; A compartment door 2, one side of the compartment door 2 is hinged to the base 1, so that the compartment door 2 can be opened and closed relative to the base 1; A first elastic member 7, the first elastic member 7 is arranged between the compartment door 2 and the base 1, and the first elastic member 7 is used to apply an outward rotational thrust to the compartment door 2; The second clamping structure 4 is provided on the door 2 of the compartment. The second clamping structure 4 includes a second elastic member 41 and a button buckle 40. The button buckle 40 is slidably provided on the door 2 of the compartment. The button buckle 40 corresponds to the first clamping structure 100 and can be clamped and matched therewith. The second elastic member 41 is connected to the first end of the button buckle 40 and is used to push the second end of the button buckle 40 to slide toward the first clamping structure 100.

[0056] In this embodiment, the base 1 can be a frame structure and is installed at the rear side of the housing 13 during use. The door 2 of the compartment is a structure installed on the base 1 and can be opened and closed, thereby opening and closing the interface of the electronic device. In this embodiment, the door 2 of the compartment is opened and closed in a rotating manner. Therefore, one side of the door 2 of the compartment is connected to the base 1 by a hinged manner. In this embodiment, the position of the hinge point is not limited and can be set on the upper side, left side, right side or lower side of the door 2 of the compartment and the base 1. The door 2 of the compartment and the base 1 can be hinged by a rotating shaft 5 or by a screw or pin structure. This embodiment does not limit it here.

[0057] To enable the door 2 of the compartment to automatically rotate outward when opened, a first elastic member 7 is provided between the door 2 of the compartment and the base 1 in this embodiment. The base 1 is used as the fixed end and the door 2 of the compartment is used as the movable end. The first elastic member 7 can apply a thrust force to the door 2 of the compartment to drive the door 2 of the compartment to rotate and open. When the door 2 of the compartment is closed, the first elastic member 7 can be compressed to obtain elastic potential energy. After the door 2 of the compartment and the base 1 are unlocked, the door 2 of the compartment can automatically rotate outward and open under the action of the first elastic member 7. In one embodiment of the first elastic member 7, the first elastic member 7 can be a spring 41, a torsion spring 70, a spring piece, etc. Since the movement of the door 2 of the compartment in this embodiment is a rotational movement, it is preferably a torsion spring 70.

[0058] To lock the door 2 of the compartment when it is closed, a first clamping structure 100 is provided on the base 1 in this embodiment, and a second clamping structure 4 corresponding to the first clamping structure 100 is provided on the door 2 of the compartment. The first clamping structure 100 and the second clamping structure 4 can be clamped and matched. In one embodiment, the second clamping structure 4 includes a second elastic member 41 and a button buckle 40. The button buckle 40 is slidably provided on the door 2 of the compartment. The sliding direction of the button buckle 40 is toward the first clamping structure 100 and away from the first clamping structure 100. The door 2 of the compartment is used as the fixed end and the button buckle 40 is used as the movable end. The second elastic member 41 can apply a thrust force to the button buckle to make it clamped and matched with the first clamping structure 100 to lock the door 2 of the compartment.

[0059] In an embodiment of the second elastic member 41, the second elastic member 41 may be a spring 410 or a spring piece. Since the movement of the button buckle 40 is a linear movement, the spring 410 is preferably used. When it is necessary to unlock the door 2, the button buckle 40 is pushed in a direction away from the first clamping structure 100 to disengage it from the first clamping structure 100. During this process, the button buckle 40 compresses the second elastic member 41. After the button buckle 40 is disengaged from the first clamping structure 100, the door 2 will automatically rotate outward and open under the action of the first elastic member 7. When closing the door 2 in a rotating manner, the button buckle 40 is subjected to a force and compresses the second elastic member 41. When the button buckle 40 is in a position directly corresponding to the first clamping structure 100, the button buckle 40 automatically snaps into the first clamping structure 100 under the elastic force of the second elastic member 41 to lock the door 2.

[0060] In this embodiment, the second clamping structure 4 may be arranged on the opposite side, the same side or the side of the hinge point of the door 2. In this embodiment, the specific position thereof is not limited herein and can be designed according to actual needs. In an embodiment, it is preferably arranged on the opposite side.

[0061] This embodiment achieves the purpose that when the door 2 needs to be closed, the door 2 can be pushed to rotate towards the base 1. When rotating to a position corresponding to the button buckle 40 and the first clamping structure 100, the button buckle 40 is clamped and cooperated with the first clamping structure 100 under the action of the second elastic member 41 to lock the door 2. When the door 2 needs to be opened, the button buckle 40 can be first operated to slide and disengage from the first clamping structure 100. At this time, the door 2 automatically rotates outward and opens under the action of the first elastic member 7, so as to realize the technical effect that the opening direction of the door 2 is not limited, and the opening and closing of the door 2 are more flexible and convenient, and further solves the problem that the opening and closing of the door 2 at the interface position of the electronic device in the related art are relatively inconvenient.

[0062] To realize the hinge connection between the door 2 and the base 1, in this embodiment, a first installation groove 101 is provided on the base 1, and a door support 11 is fixedly arranged in the first installation groove 101; An articulation part 200 is arranged on the door 2. The articulation part 200 is arranged in the door support 11, and the articulation part 200 is hinged to the door support 11 through a rotating shaft 5; The first elastic member 7 is arranged as a torsion spring 70 sleeved on the rotating shaft 5, and the two legs of the torsion spring 70 are respectively connected to the door support 11 and the door 2.

[0063] Specifically, in this embodiment, the first installation groove 101 can be arranged on the upper side of the base 1, and the door bracket 11 can be fixed in the first installation groove 101. Correspondingly, the hinge part 200 can be arranged on the upper side of the door 2. The hinge part 200 can be a structure protruding from the upper side of the door 2, and the hinge part 200 can be installed on the door bracket 11 and hinged to the door bracket 11 through the rotating shaft 5. To facilitate the automatic rotation and opening of the door 2, in this embodiment, the first elastic member 7 is a torsion spring 70 sleeved on the rotating shaft 5. After the two legs of the torsion spring 70 are respectively connected to the door bracket 11 and the door 2, the door 2 can compress the torsion spring 70 when it is closed, and the torsion spring 70 can drive the door 2 to open after being unlocked.

[0064] Since the hinge part 200 is a structure protruding from the door 2, for the convenience of installing the hinge part 200, in this embodiment, a second installation groove 110 is arranged on the door bracket 11, and the hinge part 200 is hinged in the second installation groove 110 through the rotating shaft 5. Specifically, in this embodiment, the rotating shaft 5 penetrates through the hinge part 200 transversely, and both ends of the rotating shaft 5 are connected to the side walls of the second installation groove 110.

[0065] To enable the door 2 to stop at a set position when it is opened, in this embodiment, a door 2 stop position is arranged on the second installation groove 110, and a limiting part 220 corresponding to the door 2 stop position is arranged on the hinge part 200. The maximum rotation angle of the door 2 is restricted by the limiting part 220 abutting against the door 2 stop position.

[0066] Specifically, in this embodiment, the door 2 stop position can be a convex block protruding from the second installation groove 110. The limiting part 220 can be a limiting groove opened at one end of the hinge part 200. The limiting groove corresponds to the convex block. During the process of the door 2 rotating and opening, the edge of the limiting groove gradually approaches the door 2 stop position. When the edge of the limiting groove abuts against the door 2 stop position, the rotation angle of the door 2 is restricted.

[0067] To facilitate the installation of the legs of the torsion spring 70, in this embodiment, a first leg groove 112 is arranged on the door bracket 11, and a second leg groove 210 is arranged on the door 2. The two legs of the torsion spring 70 are respectively clamped into the first leg groove 112 and the second leg groove 210.

[0068] In one implementation manner of the rotating shaft 5, the rotating shaft 5 can be set as a smooth shaft structure. When it is set as a smooth shaft, both ends of the rotating shaft 5 can be fixedly connected to the two side walls of the second installation groove 110 through adhesive or welded. In another implementation manner of the rotating shaft 5, the upper part of the rotating shaft 5 is set as a smooth shaft or a full thread, the end of the rotating shaft 5 can be set as a thread, and the end of the rotating shaft 5 can be threadedly connected to the side wall of the second installation groove 110.

[0069] In another embodiment of the rotating shaft 5, the rotating shaft 5 is provided as a long screw, the long screw is threadedly connected to the two side walls of the second mounting groove 110, and is hinged to the hinged portion 200. A capillary tube 6 is sleeved on the long screw, and a torsion spring 70 is sleeved on the capillary tube 6.

[0070] When the rotating shaft 5 is provided as a long screw, in order to prevent the torsion spring 70 sleeved on the rotating shaft 5 from jamming, an isolation sleeve is provided between the torsion spring 70 and the rotating shaft 5, and the isolation sleeve is a capillary tube 6 with a smooth surface. The capillary tube 6 is sleeved and fixed on the rotating shaft 5, and the torsion spring 70 is sleeved on the capillary tube 6. During assembly, the capillary tube 6 can be first passed through the middle of the torsion spring 70, and then the two are placed in the torsion spring 70 placement groove opened on the door 2. Furthermore, the door bracket 11 is placed on the door 2 at a position corresponding to the hinged portion 200, and the rotating shaft 5 is sequentially passed through one side of the door bracket 11, one side of the hinged portion 200, the capillary tube 6, the other side of the hinged portion 200 from one side, and finally threadedly connected to the other side of the door bracket 11.

[0071] In this embodiment, through the setting of the capillary tube 6, it is possible to reduce the jamming between the thread at the head of the rotating shaft 5 and the concave portion on the inner wall of the torsion spring 70 during assembly, making the assembly more convenient and fast. At the same time, during operation, it can ensure that the torsion spring 70 is not close to the rotating shaft 5, keep the torsion spring 70 in the correct position, and avoid the friction between the thread on the rotating shaft 5 and the side wall of the torsion spring 70, which can improve the service life of the torsion spring 70.

[0072] In one embodiment of the second clamping structure 4, the second clamping structure 4 further includes a button bracket 9, the button bracket 9 is fixedly arranged on the inner side of the door 2, a first sliding portion 90 is arranged on the button bracket 9, a second sliding portion 44 is arranged on the button buckle 40, and the first sliding portion 90 and the second sliding portion 44 are engaged and slidably connected; A sliding hole 3 is provided on the door 2, a pushing portion 42 is provided on the button buckle 40, the pushing portion 42 passes through the sliding hole 3 and extends to the outside of the door 2, and the pushing portion 42 is slidably connected to the sliding hole 3.

[0073] Specifically, in this embodiment, the button bracket 9 serves as the mounting structure of the button buckle 40, and the button bracket 9 can be arranged on the inner side of the door 2 and below the door 2. The button buckle 40 needs to slide linearly on the button bracket 9 during the clamping process, so the button bracket 9 needs to provide a reference and guidance for the sliding of the button buckle 40. In this embodiment, a first sliding portion 90 is arranged on the button bracket 9, a second sliding portion 44 is arranged on the button buckle 40, and the first sliding portion 90 and the second sliding portion 44 can be engaged and slidably connected to each other. In one embodiment, the first sliding portion 90 can be provided as a chute, and the second sliding portion 44 can be provided as a slider, and the slider is slidably connected in the chute. It can be understood that the first sliding portion 90 can also be provided as a slider, and correspondingly, the second sliding portion 44 can be provided as a chute, and this embodiment does not limit it here.

[0074] To facilitate the sliding of the button buckle 40 and its detachment from the first latching structure 100, in this embodiment, a pushing portion 42 is provided on the button buckle 40. The pushing portion 42 can be a protrusion formed on the front side of the button buckle 40. The pushing portion 42 can extend through the sliding hole 3 on the door 2, and the pushing portion 42 can be operated to push the button buckle 40 to slide.

[0075] The button bracket 9, as an independent component installed on the door 2, for ease of installation, can be fixedly connected to the door bracket 11 by screws. After being connected by screws, to avoid the exposure of the screws and improve the aesthetics while protecting the screws, in this embodiment, a shielding cover 12 is adhesively bonded to the back surface of the button bracket 9 by an adhesive 10.

[0076] Since the movement of the button buckle 40 is a linear slide, therefore, to facilitate the second elastic member 41 to push the button buckle 40 to move, the second elastic member 41 in this embodiment includes a spring 410. A third installation groove 91 is provided on the button bracket 9, and the spring 410 is disposed in the third installation groove 91. The spring 410 is connected to the first end of the button buckle 40.

[0077] In this embodiment, the upper end of the button buckle 40 can be partially disposed in the third installation groove 91. The upper end of the spring 410 abuts against the upper wall of the third installation groove 91, and the lower end of the spring 410 is connected to the upper end of the button buckle 40, which can be a sleeved connection relationship. When it is necessary to unlock the door 2, the pushing portion 42 can be manually operated to slide the button buckle 40 upward to disengage it from the first latching structure 100. During this process, the button buckle 40 compresses the spring 410.

[0078] Since the button buckle 40 and the first latching structure 100 are in a latching fit, in one embodiment, a slot 1000 is provided on the first latching structure 100, and a latching protrusion 43 is provided at one end of the button buckle 40 away from the second elastic member 41. The latching protrusion 43 is in a latching fit with the slot 1000.

[0079] To facilitate the closing of the door 2, as Figure 12 shown, in this embodiment, a first guiding inclined surface 430 is provided on the inner side of the latching protrusion 43, and a second guiding inclined surface 1001 that cooperates with the first guiding inclined surface 430 is provided on the outer side of the first latching structure 100. When closing the door 2, the door 2 can be pushed to rotate. When the door 2 rotates until the first guiding inclined surface 430 and the second guiding inclined surface 1001 come into contact, as the door 2 further rotates, under the action of the guiding inclined surface, the button buckle 40 will automatically slide upward. When the door 2 rotates until the latching protrusion 43 on the button buckle 40 directly corresponds to the slot 1000, the button buckle 40 slides outward under the action of the spring 410, so that the latching protrusion 43 snaps into the slot 1000, thereby realizing the locking of the door 2.

[0080] To improve the sealing performance of the storage door 2 after it is closed, as Figure 14 shown, the structure of the storage door 2 in this embodiment further includes a soft rubber strip 8, and the soft rubber strip 8 is fixedly arranged on the inner side of the storage door 2 and arranged around the edge of the storage door 2. When the storage door 2 is closed, there is a certain interference amount between the soft rubber strip 8 and the base 1, so that the soft rubber strip 8 is slightly compressed, playing a role in dust and water prevention.

[0081] As Figure 13 shown, in one embodiment, the outer side of the side wall of the storage door 2 is set as an inclined surface 200, so that the gap at the place where the appearance is separated from the base 1 can be made very small, such as 0.2 mm, improving the appearance level. At the same time, during the opening and closing process, the side wall of the storage door 2 is prevented from contacting and rubbing against the side wall of the base 1, generating noise and abnormal feel.

[0082] To facilitate the installation of the battery module 33, as Figures 16 to 18 shown, the battery module 33 in this embodiment includes: A module main body, the module main body includes a housing 334 and a battery cell assembly 336, and the battery cell assembly 336 is arranged in the housing 334; A sliding buckle 335, the sliding buckle 335 is arranged on the housing 334 of the battery module 33. The sliding buckle 335 includes an elastic part 3355, a sliding part 3350 and a clamping part 3351. The first end of the sliding part 3350 is connected to the elastic part 3355, and the second end of the sliding part 3350 is connected to the clamping part 3351. The clamping part 3351 can partially extend out of the housing 334 along the first direction under the action of the elastic part 3355, and the first direction is opposite to the installation and disassembly direction of the module main body; An installation groove that is engaged and matched with the clamping part 3351 is arranged on the inner wall of the battery installation bin.

[0083] In this embodiment, the sliding buckle 335 is arranged on the housing 334 of the battery module 33, so that there is no need to leave extra space on the outer shell 13 to install the buckle, effectively reducing the volume of the device and further improving its portability.

[0084] On this basis, in this embodiment, the elastic part 3355 of the sliding buckle 335 can make the clamping part 3351 partially extend out of the housing 334 in the first direction in the natural state. It should be noted that the first direction is different from the installation and disassembly direction of the module body. In one implementation, the first direction is perpendicular to the installation direction of the module body. When assembling the battery module 33, an external force is applied to the elastic part 3355 of the sliding buckle 335 to cause it to undergo compressive deformation in the first direction. At this time, the clamping part 3351 compresses the elastic part 3355 and slides in the first direction, causing the part that originally extended out of the housing 334 to retract into the housing 334, so that the entire battery module 33 can move relative to the body of the portable gas leak detection imager to achieve installation and disassembly. After the battery module 33 is sent into the instrument in the installation direction, when it reaches the preset installation position and the external force is cancelled, the elastic part 3355 resets, causing the clamping part 3351 to extend out of the housing 334 partially again in the first direction and engage with the portable gas leak detection imager, thus completing the assembly of the battery module 33.

[0085] When it is necessary to disassemble the battery module 33, an external force is also applied to the elastic part 3355 of the sliding buckle 335 to cause it to undergo compressive deformation in the first direction. The clamping part 3351 retracts into the housing 334 under the action of the elastic part 3355, releasing its engagement state with the portable gas leak detection imager. At this time, when the clamping part 3351 retracts into the housing 334, the entire battery module 33 can move relative to the body of the portable gas leak detection imager, so that the battery module 33 can be taken out smoothly.

[0086] Furthermore, a guiding inclined surface is provided on the clamping part 3351. Specifically, in this embodiment, the guiding inclined surface is provided on the inner side of the clamping part 3351. After the guiding inclined surface is provided, when the module body is pushed to the installation slot of the battery installation bin, as the module body is pushed in, the clamping part 3351 gradually approaches the opening end face of the installation slot. When the guiding inclined surface of the clamping part 3351 abuts against the opening end face of the installation slot, as the module body is further pushed in, the clamping part 3351 automatically slides inward under the action of the guiding inclined surface and compresses the elastic part 3355. When the module body is pushed to the set installation position, the clamping part 3351 corresponds to the clamping slot 1000 in the installation slot. At this time, the clamping part 3351 slides out under the action of the elastic part 3355 and snaps into the clamping slot 1000.

[0087] Since the movement of the clamping part 3351 is linear sliding, in order to facilitate the movement of the clamping part 3351, the elastic part 3355 in this embodiment is set as a spring 410.

[0088] Further, a shift block 331 is provided on the sliding portion 3350, a strip-shaped through hole 333 is provided on the upper edge of the housing 334, the length direction of the strip-shaped through hole 333 is parallel to the first direction, the end of the shift block 331 extends out of the housing 334 through the strip-shaped through hole 333, and the shift block 331 is slidably connected to the strip-shaped through hole 333; Specifically, in the present embodiment, the shift block 331 extends out of the shell 334 through the bar-shaped through hole 333, so that the user can conveniently operate it with hands or tools, thereby improving the convenience of use; the shift block 331 is slidably connected to the bar-shaped through hole 333, which can avoid lateral displacement of the shift block 331 during use, thereby improving the accuracy and stability of the operation; according to needs, the bar-shaped through hole 333 and the shift block 331 of different lengths can be designed to meet specific application requirements, providing greater design flexibility.

[0089] Furthermore, a first slide rail is disposed in the housing 334, and a first slide groove 3353 slidably connected to the first slide rail is disposed on the sliding portion 3350; Specifically, in this embodiment, the first slide rail is slidably connected to the first slide groove 3353, which can realize the flexible movement of the sliding buckle 335 inside the shell 334, so as to facilitate adjustment and adapt to different working conditions. At the same time, it can reduce friction, improve sliding smoothness, and extend service life; in addition, it can also enhance the stability of the structure, make the overall structure more compact, and save space.

[0090] Furthermore, it also includes a buckle pressure plate 337, which is arranged in the shell 334, and a second slide rail 33700 is arranged on the buckle pressure plate 337. The second slide rail 33700 and the first slide rail are respectively located on the upper and lower sides of the sliding part 3350, and the sliding part 3350 is provided with a second slide groove 3354 that is slidably connected to the second slide rail 33700.

[0091] Specifically, in this embodiment, the first slide rail and the second slide rail 33700 are respectively located on the upper and lower sides of the sliding part 3350, and can provide two-way support, so that the sliding part 3350 is more stable during movement. This dual support system effectively reduces the shaking and deviation of the sliding part 3350, and improves the accuracy of the overall operation; the cooperation between the first slide rail and the first slide groove 3353, and the second slide rail 33700 and the second slide groove 3354 can ensure that the sliding part 3350 remains uniform and stable during the entire sliding process, reduce friction and sticking, and thus improve the sliding performance.

[0092] Furthermore, the housing 334 includes an upper housing 330 and a lower housing 332 , the first slide rail is fixed to the lower housing 332 , and the upper housing 330 and the lower housing 332 are detachably fixedly connected and pressed onto the buckle pressing plate 337 .

[0093] Specifically, in this embodiment, the detachable design of the upper shell 330 and the lower shell 332 makes the assembly process of the battery module 33 simpler. The user can first install the slide rails and other internal components into the lower shell 332, and then cover and fix the upper shell 330 to complete the entire assembly. When the equipment needs maintenance or overhaul, the internal components can be easily accessed by removing the upper shell 330 without disassembling the entire equipment.

[0094] It should be noted that after the upper shell 330 and the lower shell 332 are fixedly assembled, the upper shell 330 can limit the buckle pressure plate 337 to provide additional structural stability and ensure the smooth movement of the sliding part 3350 on the slide rail.

[0095] Furthermore, the buckle pressure plate 337 includes a horizontal portion 3370 , a second slide rail 33700 is disposed on the bottom surface of the horizontal portion 3370 , and a pressure block is disposed in the upper shell 330 , and the pressure block is pressed on the buckle pressure plate 337 ; Furthermore, the buckle pressing plate 337 also includes a vertical portion 3372, the upper end of the vertical portion 3372 is fixedly connected to the horizontal portion 3370, the lower end of the vertical portion 3372 is provided with a first slot 33720, the first slide rail is provided with a second slot, and the vertical portion 3372 and the first slide rail are plugged and matched through the first slot 33720 and the second slot; Specifically, in this embodiment, the bottom surface of the horizontal part 3370 is provided with a second slide rail 33700, which can cooperate with the second slide groove 3354 of the sliding part 3350 to achieve smooth sliding. The design of the horizontal part 3370 helps to provide a stable support surface to ensure that the slide rail and the slide groove are accurately connected; the upper end of the vertical part 3372 is fixedly connected to the horizontal part 3370, and the lower end is provided with a first slot 33720. The vertical part 3372 provides vertical stability for the buckle pressure plate 337, so that it can maintain a fixed position in the device and will not change its position due to gravity or vibration. The pressing block is arranged in the upper shell 330, which can press the buckle pressure plate 337, ensuring that the position of the buckle pressure plate 337 is stable after the device is assembled, and avoiding the displacement of the buckle pressure plate 337 due to vibration or other external forces during use. The function of the pressing block is to fix the buckle pressure plate 337 in a preset position. This pressing design can effectively reduce the shaking of the component and improve the stability of the sliding part 3350.

[0096] Furthermore, the vertical portion 3372 is disposed in the middle of the horizontal portion 3370 , and two groups of sliding buckles 335 are disposed and are symmetrical about the vertical portion 3372 . The ends of the elastic portions 3355 of the two sliding buckles 335 away from the clamping portion 3351 both contact the vertical portion 3372 .

[0097] Specifically, in this embodiment, placing the vertical portion 3372 at the middle position of the horizontal portion 3370 is to optimize the symmetry and stability of the structure. Such a position arrangement can ensure uniform distribution of the force on the snap clamp plate 337, avoiding structural deformation or instability caused by overweight or unbalanced forces. The two sets of sliding snaps 335 are provided to offer a more stable fixing mechanism. Each set of sliding snaps 335 is respectively arranged on the left and right sides of the vertical portion 3372. This symmetrical design can provide balanced fixing force, making the whole structure more stable during use. The contact between the elastic portion 3355 and the vertical portion 3372 can provide additional fixing force. A limit groove matching the end face of the elastic portion 3355 can be formed at the position where the elastic portion 3355 contacts the vertical portion 3372.

[0098] Furthermore, the operation knob 24 includes an encoder switch and a knob, and the housing 13 is provided with a mounting hole. The encoder switch is fixedly arranged inside the housing 13 and electrically connected to the main control module. A part of the knob slides through the mounting hole and is fixedly connected to the encoder switch, and the other part of the knob is located outside the housing 13.

[0099] Furthermore, a quarter-inch fixing port 25 and a foot pad 26 are arranged at the lower end of the housing 13. Specifically, in this embodiment, by providing the quarter-inch fixing port 25, the infrared imager can be fixed on existing photographic equipment such as a tripod for fixed detection and video recording operations. The foot pad 26 is made of a soft rubber material such as silicone rubber, which can improve the hand feeling and reduce noise when the machine is placed on a hard surface.
