Description

Technical Field

[0001] This utility model belongs to the technical field of natural gas leak detectors, specifically relating to a portable foldable natural gas leak detector. Background Technology

[0002] Natural gas leak detectors (also known as portable gas leak detectors) are key equipment in the field of gas safety assurance. Through the deep integration of high-precision sensors and intelligent technology, they can achieve rapid and accurate detection of gas leaks and issue alarms immediately, providing strong technical support for preventing gas safety accidents. This device is equipped with advanced sensors such as infrared lasers, catalytic combustion sensors, or semiconductor sensors, boasting extremely high detection sensitivity. It can capture natural gas concentration changes as low as ppm (parts per million) or even ppb (parts per billion). By monitoring minute fluctuations in natural gas concentration in real time, it can accurately determine whether a leak has occurred—a performance far exceeding that of traditional detection equipment.

[0003] When using a natural gas leak detector, the inspector carries it to conduct inspections, that is, to detect whether there is a natural gas leak in different locations. However, most detectors on the market currently adopt a handheld design. Although this design is convenient for handheld operation, the presence of a handle undoubtedly increases the overall length of the device, making the overall size of the device larger, and thus reducing its portability to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a portable foldable natural gas leak detector, which aims to solve the problem that in the existing technology, when using natural gas leak detectors, the inspectors carry the detectors to inspect for leaks in different locations. However, most detectors on the market currently adopt a handheld design. Although this design is convenient for handheld operation, the presence of a handle undoubtedly increases the overall length of the device, making the overall size of the device larger, and thus reducing its portability to a certain extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable foldable natural gas leak detector, comprising an operation panel, a detection probe connected to the back end of the operation panel, a docking block connected to the front end of the operation panel, a handle rotatably connected inside the docking block, a circular block connected to the side wall of the docking block, a pull rod inserted inside the circular block, a spring sleeved on the surface of the pull rod, a limit block fixedly connected to the surface of the pull rod, a locking pin threaded through the side wall of the docking block away from the circular block, a first magnetic block connected to the bottom end of the handle, and a second magnetic block connected inside the recess at the bottom end of the operation panel.

[0006] As a preferred embodiment of this portable folding natural gas leak detector, the pull rod can be elastically telescopically connected to the circular block via a spring and a limiting block, and the pull rod passes through the docking block and is connected to the opening on the side wall of the handle.

[0007] As a preferred embodiment of this portable folding natural gas leak detector, the locking pin passes through the docking block and connects to the opening on the side wall of the handle.

[0008] As a preferred embodiment of this portable folding natural gas leak detector, the handle can be detachably and fixedly connected to the docking block via a pull rod, spring, limiting block, circular block and locking pin.

[0009] As a preferred embodiment of the portable folding natural gas leak detector of this utility model, the handle can be magnetically fixedly connected to the operation panel via a first magnetic block and a second magnetic block.

[0010] As a preferred embodiment of the portable foldable natural gas leak detector of this utility model, a rectangular block is connected to the side wall of the operation panel, a bidirectional threaded rod is assembled inside the rectangular block, two threaded sleeves are symmetrically threaded on the surface of the bidirectional threaded rod, and a clamping block is connected to the side wall of the threaded sleeve.

[0011] As a preferred embodiment of this portable foldable natural gas leak detector, the clamping block can form a threaded drive with a bidirectional threaded rod through a threaded sleeve, and the opening size of the threaded sleeve is adapted to the side wall of the rectangular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Through the coordinated action of the pull rod, spring, limit block, circular block, and locking pin, the grip can be easily released from its fixed position, allowing it to rotate smoothly along the mating block and fold into the recess at the bottom of the control panel. Subsequently, it is securely fixed by the magnetic attraction of the first and second magnetic blocks. This folding design effectively reduces the overall size of the device and significantly improves portability.

[0014] The connection between the bidirectional threaded rod, threaded sleeve, and clamping block can securely fix the probe's connecting wire in the recess of the clamping block, thereby effectively preventing damage or interference to the probe caused by the connecting wire swinging during transport, ensuring the safety and stability of the equipment.

[0021] 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.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a portable foldable natural gas leak detector, including an operation panel 1, a detection probe 3 connected to the back end of the operation panel 1, a docking block 4 connected to the front end of the operation panel 1, a handle 2 rotatably connected inside the docking block 4, a circular block 5 connected to the side wall of the docking block 4, a pull rod 6 inserted inside the circular block 5, a spring 7 sleeved on the surface of the pull rod 6, a limit block 8 fixedly connected to the surface of the pull rod 6, a locking pin 9 threaded through the side wall of the docking block 4 away from the circular block 5, a first magnetic block 10 connected to the bottom end of the handle 2, and a second magnetic block 11 connected inside the bottom recess of the operation panel 1.

[0023] In practical use, the natural gas leak detector consists of a control panel 1, a detection probe 3, a handle 2, and a docking block 4. Its model is JL269 Gas Leak Detector. During actual use, the operator holds the handle 2 to stabilize the device and then starts it via the control panel 1. After starting, the detection probe 3 is placed close to the natural gas pipeline to detect any leaks using its high-precision sensor. After inspecting one pipeline, the operator moves the detection probe 3 to other natural gas pipelines and repeats the above steps to achieve a comprehensive inspection of the natural gas pipeline system, ensuring timely detection and handling of potential leaks.

[0024] Preferably, the pull rod 6 can be elastically telescopically connected to the circular block 5 via the spring 7 and the limiting block 8. The pull rod 6 passes through the docking block 4 and connects to the opening on the side wall of the handle 2. The locking pin 9 passes through the docking block 4 and connects to the opening on the side wall of the handle 2. The handle 2 can be detachably and fixedly connected to the docking block 4 via the pull rod 6, the spring 7, the limiting block 8, the circular block 5, and the locking pin 9. The handle 2 can be magnetically fixedly connected to the operation panel 1 via the first magnetic block 10 and the second magnetic block 11.

[0025] In practical use, the handle 2 and the docking block 4 are connected by a rotating design. A locking pin 9 is threaded through the side wall of the docking block 4. The operator only needs to rotate the locking pin 9 to disengage it from the docking block 4, allowing it to move out of the opening in the side wall of the handle 2, thus releasing the handle 2 from its fixation. Furthermore, a circular block 5 is connected to the side wall of the docking block 4. When the pull rod 6 inside the circular block 5 is pulled, the pull rod 6 causes the limiting block 8 to compress the spring 7, causing the spring 7 to contract. The pull rod 6 then moves out of the opening in the side wall of the handle 2, thus releasing the connection between the pull rod 6 and the handle 2. By operating the pull rod 6 and the locking pin 9, the locking state of the handle 2 can be easily released. The handle 2 can then be rotated and stored in the recess at the bottom of the operating panel 1, where it is securely fixed by the magnetic attraction of the first magnetic block 10 and the second magnetic block 11. This folding design effectively reduces the overall size of the device and significantly improves portability.

[0026] If the handle 2 needs to be unscrewed from the recess at the bottom of the control panel 1 for use, the operator must first disconnect the locking pin 9 from the docking block 4, and then pull the lever 6 to move it. After the handle 2 rotates into the recess of the docking block 4, first release the lever 6. The lever 6 will return to its original position under the elastic force of the spring 7 and be inserted into the opening on the side wall of the handle 2. Then reconnect the locking pin 9 to the docking block 4 so that the locking pin 9 passes through the docking block 4 and is threaded into the opening on the side wall of the handle 2, thereby fixing the handle 2 and preventing the movement of the handle 2 from affecting the normal use of the equipment.

[0027] Preferably, a rectangular block 12 is connected to the side wall of the operation panel 1, and a bidirectional threaded rod 13 is assembled inside the rectangular block 12. Two threaded sleeves 14 are symmetrically threaded on the surface of the bidirectional threaded rod 13, and a clamping block 15 is connected to the side wall of the threaded sleeve 14. The clamping block 15 can form a threaded drive with the bidirectional threaded rod 13 through the threaded sleeves 14, and the opening size of the threaded sleeves 14 is adapted to the side wall of the rectangular block 12.

[0028] In practical use, the operator controls the bidirectional threaded rod 13 to rotate clockwise. At this time, the bidirectional threaded rod 13 will rotate stably within the rectangular block 12 along the inner ring of the bearing. As the bidirectional threaded rod 13 rotates, the two threaded sleeves 14 will gradually approach each other along their threaded paths. Because the external dimensions of the threaded sleeves 14 are adapted to the openings in the sidewalls of the rectangular block 12, this design effectively restricts the rotational freedom of the threaded sleeves 14, preventing them from rotating along with the bidirectional threaded rod 13.

[0029] As the threaded sleeve 14 moves, the clamping blocks 15 connected to it also begin to move closer together. The operator can place the connecting wire of the detection probe 3 into the arc-shaped opening of the clamping block 15. When the two clamping blocks 15 are tightly fitted together by the action of the threaded sleeve 14, the connecting wire of the detection probe 3 will be firmly fixed. This design effectively avoids damage or interference to the detection probe 3 that may be caused by the swinging of the connecting wire during transport, thereby ensuring the safety and stability of the equipment.

[0030] Working Principle: When using the natural gas leak detector to inspect and detect natural gas leaks, this device features a clever folding design to enhance portability. Specifically, a locking pin 9 is threaded through the side wall of the docking block 4. The operator simply rotates the locking pin 9 to disengage it from the docking block 4, allowing it to move out of the opening on the side wall of the handle 2, thus releasing the handle 2 from its fixation. Simultaneously, a circular block 5 is connected to the side wall of the docking block 4. Pulling the lever 6 inside the circular block 5 causes the lever 6 to drive the limiting block 8 to compress the spring 7, causing the spring 7 to contract. The lever 6 then moves out of the opening on the side wall of the handle 2, releasing the connection between the lever 6 and the handle 2. By operating the lever 6 and the locking pin 9, the locking state of the handle 2 can be easily released. The handle 2 can then be rotated and stored in the recess at the bottom of the operating panel 1, where it is securely fixed by the magnetic attraction of the first magnetic block 10 and the second magnetic block 11. This effectively reduces the overall size of the device and significantly improves portability.

[0031] Furthermore, to ensure the safety of the probe 3 connection cable during transport, the operator controls the bidirectional threaded rod 13 to rotate clockwise. At this time, the bidirectional threaded rod 13 will rotate stably within the rectangular block 12 along the inner ring of the bearing. As the bidirectional threaded rod 13 rotates, the two threaded sleeves 14 gradually approach each other along their threaded paths. With the movement of the threaded sleeves 14, the connected clamping blocks 15 also approach each other. The operator can place the probe 3 connection cable within the arc-shaped opening of the clamping block 15. When the two clamping blocks 15 are tightly fitted, the probe 3 connection cable is securely fixed, preventing damage or interference to the probe 3 due to cable swaying during transport, thus ensuring the safety and stability of the equipment.

[0032] After carrying the device to the natural gas testing area, the operator must first disconnect the locking pin 9 from the docking block 4. Then, pull the lever 6 to move it until the handle 2 rotates into the recess of the docking block 4. Release the lever 6, and it will return to its original position under the elastic force of the spring 7 and engage with the opening on the side wall of the handle 2. Then, reconnect the locking pin 9 to the docking block 4, allowing it to pass through the docking block 4 and be threaded into the opening on the side wall of the handle 2. This secures the handle 2 and prevents its movement from affecting the normal operation of the equipment. Next, the operator holds the handle 2 to stabilize the device and starts it via the control panel 1. After starting, place the detection probe 3 close to the natural gas pipeline and use its high-precision sensor to detect any natural gas leaks. After completing the inspection of one pipeline, the operator moves the detection probe 3 to other natural gas pipelines and repeats the above inspection steps to achieve a comprehensive inspection of the natural gas pipeline system, ensuring timely detection and handling of potential leak risks.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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.
