Description

Technical Field

[0002] Natural gas is an important fuel in modern society, with advantages such as ease of use and low pollution. However, if a gas leak occurs, it can cause serious accidents. Therefore, gas leak detection devices are needed to detect gas leaks so that leaks can be dealt with in a timely manner. At present, although existing gas leak detection devices are small and portable, the detection probe lacks an effective protective structure during transport. As a core component, the probe is exposed to the outside for a long time, which can easily cause damage to its internal precision structure due to collisions. This will affect the detection accuracy and sensitivity of the probe, and even shorten its lifespan.

[0003] As disclosed in the prior art, Chinese utility model publication CN218956006U discloses a gas leak detection device. This utility model includes a housing, a controller and a battery inside the housing, a touch screen on one side of the housing, a serpentine tube at one end of the housing, and a probe at the end of the serpentine tube away from the housing. In the above structure, since there is no related probe protection structure, the probe is exposed to the outside for a long time during actual use and is prone to collision with external objects, causing damage. That is, the problem of easily damaged detection probe mentioned above exists. Therefore, we need to propose a portable gas leak detection device. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A portable gas leak detection device includes: a detector body 1; a connecting pipe 2 installed on the top of the detector body 1; a detection probe 3 installed at one end of the connecting pipe 2; and a protective mechanism 4 for storing and protecting the detection probe 3, wherein the protective mechanism 4 is located on one side of the detector body 1.

[0025] The protective mechanism 4 can be used to store and protect the detection probe 3. When carrying or not in use, the protective mechanism 4 can store the probe to prevent damage to the internal structure caused by collision, ensure the stability of detection accuracy and sensitivity, and extend the service life of the detection probe 3.

[0026] Specifically, the protective mechanism 4 includes a protective base 41, a snap-fit ​​groove 42, two sets of protective covers 43, and two sets of arc-shaped grooves 44. The protective base 41 is fixedly installed on one side of the detector body 1, and the top of the protective base 41 is provided with a snap-fit ​​groove 42 for the detection probe 3 to be inserted. Both sets of protective covers 43 are located on the top of the protective base 41, and arc-shaped grooves 44 are provided on the opposite side of both sets of protective covers 43.

[0027] With the setting of protective base 41, snap-fit ​​groove 42, two sets of protective covers 43 and two sets of arc grooves 44, the protective base 41 and snap-fit ​​groove 42 provide a stable storage space for the detection probe 3, and the two sets of protective covers 43 and arc grooves 44 form a complete protective shell, ensuring all-round protection for the detection probe 3, thereby effectively preventing external collisions from damaging the detection probe 3.

[0028] The diameter of the detection probe 3 is larger than that of the connecting pipe 2, the inner wall of the snap-fit ​​groove 42 is adapted to the inner wall of the detection probe 3, and the interior of both sets of arc grooves 44 is adapted to the outer wall of the connecting pipe 2.

[0029] With the setting of the snap-fit ​​groove 42 and the arc groove 44, the inner wall of the snap-fit ​​groove 42 is adapted to the outer wall of the detection probe 3, which can ensure the stability of the detection probe 3 when it is inserted; the arc groove 44 is adapted to the outer wall of the connecting pipe 2, and when the two sets of protective covers 43 are closed, the two arc grooves 44 form a closed loop with a diameter smaller than the diameter of the detection probe 3, thereby playing a limiting protection role for the detection probe 3 and preventing it from accidentally slipping out.

[0030] Specifically, L-shaped connecting plates 5 are fixedly installed on one side of each of the two sets of protective covers 43, and sliders 6 are fixedly installed at the bottom of each of the two sets of L-shaped connecting plates 5. Support plates 7 are fixedly installed on both sides of the protective seat 41, and grooves 8 for sliders 6 to slide are opened on the top of each of the two sets of support plates 7.

[0031] With the L-shaped connecting plate 5, support plate 7, slider 6 and slide groove 8, the L-shaped connecting plate 5 facilitates the opening and closing of the protective cover 43. The slider 6 at the bottom of the L-shaped connecting plate 5 slides in the slide groove 8 on the support plate 7, allowing the two sets of protective covers 43 to move smoothly in opposite directions, thus achieving smooth sliding of the protective cover 43, making the opening and closing operation smoother and improving the ease of use.

[0032] In a further preferred embodiment, two limiting mechanisms 9 are also included to limit and fix the two sets of protective covers 43, and the limiting mechanisms 9 are disposed on one side of the support plate 7.

[0033] By setting the limiting mechanism 9, the limiting mechanism 9 can fix the protective cover 43 after it is closed, preventing the protective cover 43 from being opened accidentally, and ensuring that the protective mechanism 4 continues to protect the detection probe 3 during the carrying process.

[0034] Specifically, the limiting mechanism 9 includes a limiting pin 91, a limiting ring 92, a connecting rope 93, a limiting block 94, a through groove 95, and a limiting groove 96; the limiting pin 91 is fixedly installed on one side of the support plate 7, the limiting ring 92 is sleeved on the outside of the limiting pin 91, one end of the connecting rope 93 is set on the limiting ring 92, and the other end of the connecting rope 93 is set on the top of the limiting block 94; the inside of the protective cover 43 is provided with a through groove 95 for the limiting block 94 to pass through, and the top of the protective seat 41 is provided with a limiting groove 96 for the limiting block 94 to be inserted into.

[0035] By setting up the limiting pin 91, limiting ring 92, connecting rope 93, limiting block 94, through groove 95 and limiting groove 96, the limiting block 94 is inserted into the through groove 95 and limiting groove 96, thereby achieving the limiting and fixing of the protective cover 43 and preventing the protective cover 43 from opening accidentally. The cooperation of the connecting rope 93, limiting pin 91 and limiting ring 92 can prevent the limiting block 94 from being lost, thus enhancing the reliability of the protective mechanism 4.

[0036] The limiting block 94 has a triangular cross-section, and the outer wall of the limiting block 94 is adapted to the inner wall of the through groove 95 and the limiting groove 96.

[0037] With the setting of the limiting block 94, the cross section of the limiting block 94 is triangular and is adapted to the inner wall of the through groove 95 and the limiting groove 96. After insertion, it can form a tight limiting effect, prevent the protective cover 43 from loosening, and improve the fixing strength of the protective mechanism 4.

[0038] Specifically, magnetic strips 10 are provided on the opposite sides of the two sets of protective covers 43.

[0039] With the magnetic strips 10 in place, the magnetic strips 10 on the opposite sides of the two sets of protective covers 43 can attract each other when the protective covers 43 are closed, further enhancing the closing stability of the protective covers 43, ensuring the airtightness of the protective space, and reducing the influence of external factors on the detection probe 3.

[0040] Working principle: When using this utility model, firstly, align the detection probe 3 with the snap-fit ​​groove 42 on the top of the protective base 41. Since the inner wall of the snap-fit ​​groove 42 is compatible with the outer wall of the detection probe 3, the detection probe 3 can be stably inserted into the snap-fit ​​groove 42. Next, push the two sets of protective covers 43. The protective covers 43 slide along the sliding groove 8 on the top of the support plate 7 through the slider 6 at the bottom of the L-shaped connecting plate 5, so that the two sets of protective covers 43 move towards each other and cover the protective base 41. At this time, the arc groove 44 on the opposite side of the two sets of protective covers 43 will fit against the outer wall of the connecting pipe 2, which will limit the connection pipe 2.

[0041] When the protective cover 43 is closed, the magnetic strips 10 on the opposite side of the two sets of protective covers 43 will automatically attract each other, providing initial locking. Then, the limiting mechanism 9 limits and fixes the two sets of protective covers 43. The limiting block 94 is inserted into the through groove 95 inside the protective cover 43 and embedded in the limiting groove 96 at the top of the protective seat 41. Since the cross-section of the limiting block 94 is triangular and its outer wall is compatible with the inner wall of the through groove 95 and the limiting groove 96, the protective cover 43 can be limited and fixed after insertion, thus forming a complete protective space that can store and protect the detection probe 3, effectively preventing the detection probe 3 from being affected by external factors such as collisions.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
