[0046] The utility model has a simple structure, a scientific and reasonable design, and is easy to use. When the utility model is not in use, the whole is placed in a protective shell, which is small in size and reduces space occupation. A handle that is convenient for people to hold is provided on the protective shell, so that it is easy to carry. When the utility model is in use, the handle on the fixed seat is held, and the corresponding telescopic mechanism on the fixed seat is extended, and then the extended telescopic mechanism is inserted into the disaster site to use the liquid detection mechanism or the gas detection mechanism on the telescopic mechanism to perform liquid or gas detection, which is easy to use.

[0047] Example 2

[0048] like Figure 1-22As shown, the utility model provides a portable detection rod, including a protective shell 2, and a detection rod body 1 stored in the protective shell 2; the detection rod body 1 includes a fixed base 3, a handle 4 arranged at one end of the fixed base 3, two telescopic mechanisms arranged at the other end of the fixed base 3 and distributed parallel to each other, and a liquid detection mechanism arranged on one telescopic mechanism and a gas detection mechanism arranged on the other telescopic mechanism.

[0049] The telescopic mechanism includes a first telescopic rod 5 slidably arranged in the fixing seat 3, a second telescopic rod 6 slidably arranged in the first telescopic rod 5, and a third telescopic rod 7 slidably arranged in the second telescopic rod 6; the liquid detection mechanism and the gas detection mechanism are respectively arranged on the corresponding third telescopic rod 7.

[0050] In this embodiment 2, when in use, the detection rod body 1 is taken out from the protective shell 2, and the first telescopic rod 5, the second telescopic rod 6 and the third telescopic rod 7 are respectively extended to lengthen the overall length of the detection rod body 1, so as to facilitate the liquid detection mechanism or the gas detection mechanism on the third telescopic rod 7 to be inserted into the disaster site for detection. After use, the first telescopic rod 5, the second telescopic rod 6 and the third telescopic rod 7 are respectively shortened to shorten the overall length of the detection rod body 1, so as to facilitate the detection rod body 1 to be accommodated in the protective shell 2, reduce space occupation, and be convenient to carry.

[0051] Example 3

[0052] like Figure 1-22 As shown, the utility model provides a portable detection rod, including a protective shell 2, and a detection rod body 1 stored in the protective shell 2; the detection rod body 1 includes a fixed base 3, a handle 4 arranged at one end of the fixed base 3, two telescopic mechanisms arranged at the other end of the fixed base 3 and distributed parallel to each other, and a liquid detection mechanism arranged on one telescopic mechanism and a gas detection mechanism arranged on the other telescopic mechanism.

[0053] The telescopic mechanism includes a first telescopic rod 5 slidably arranged in the fixing seat 3, a second telescopic rod 6 slidably arranged in the first telescopic rod 5, and a third telescopic rod 7 slidably arranged in the second telescopic rod 6; the liquid detection mechanism and the gas detection mechanism are respectively arranged on the corresponding third telescopic rod 7.

[0054] The fixing seat 3 is provided with a first guide hole 13 and a first limit hole 14 which are interconnected. The first telescopic rod 5 is movably inserted into the first guide hole 13 and the first limit hole 14. A first limit block 15 which is adapted to the first limit hole 14 is provided on one end of the first telescopic rod 5 located in the first guide hole 13.

[0055] In the present embodiment 3, two opposite first accommodating cavities 37 are provided on the first limit block 15, a first yielding groove 38 connected to the first accommodating cavity 37 is provided on the first limit block 15, a first spring 39 is provided in the first accommodating cavity 37, one end of the first spring 39 is fixed to the inner wall of the first accommodating cavity 37, and the other end is connected to the first locking ball 40, and a first locking hole 41 adapted to the first locking ball 40 is provided on the inner wall of the first limit through hole 14.

[0056] When the first telescopic rod 5 is extended, the first telescopic rod 5 is slid in the direction away from the fixed seat 3, so that the first telescopic rod 5 is extended outward. During the sliding process of the first telescopic rod 5, the first limit block 15 thereon is driven to slide synchronously, and the first limit block 15 drives the first clamping ball 40 thereon to move synchronously. During the movement of the first clamping ball 40, the first clamping ball 40 is squeezed by the inner wall of the first guide hole 13 or the first limit through hole 14, and the squeezed first clamping ball 40 presses the first spring leaf 39. The first spring leaf 39 is elastically deformed by the force and drives the first clamping ball 40 to move in the direction close to the axis of the first telescopic rod 5, so that the first clamping ball 40 passes through the first stop hole 14. The positioning slot 38 is retracted into the first accommodating chamber 37, so that the first telescopic rod 5 can slide smoothly in the first guide hole 13 or the first limiting through hole 14. The first telescopic rod 5 continues to slide until the first clamping ball 40 thereon is opposite to the first locking hole 41, and the inner wall of the first limiting through hole 14 releases the squeezing of the first clamping ball 40. At the same time, the first clamping ball 40 releases the squeezing of the first spring 39. The first spring 39 restores its shape and drives the first clamping ball 40 to move synchronously during the process of restoring its shape. The first clamping ball 40 pops out from the first accommodating chamber 37 into the first locking hole 41. In this way, the first telescopic rod 5 is clamped on the fixing seat 3.

[0057] When the first telescopic rod 5 needs to be shortened, the first telescopic rod 5 is pushed forcefully toward the fixing seat 3, so that the first locking ball 40 is squeezed by the inner wall of the first limiting through hole 14 and retracted from the first locking hole 41 into the first accommodating cavity 37, and then the first telescopic rod 5 is continuously pushed to shorten the length of the first telescopic rod 5 until the first telescopic rod 5 cannot slide anymore.

[0061] The first telescopic rod 5 is provided with a second guide hole 16 and a second limit hole 17 which are interconnected. The second telescopic rod 6 is movably inserted into the second guide hole 16 and the second limit hole 17. A second limit block 18 which is adapted to the second limit hole 17 is provided on one end of the second telescopic rod 6 which extends into the second guide hole 16.

[0062] In this embodiment 4, two opposite second accommodating cavities 42 are provided on the second limit block 18, and a second yielding groove 43 connected to the second accommodating cavity 42 is provided on the second limit block 18. A second spring 44 is provided in the second accommodating cavity 42, and one end of the second spring 44 is fixed to the inner wall of the second accommodating cavity 42, and the other end is connected to the second locking ball 45, and a second locking hole 46 adapted to the second locking ball 45 is provided on the inner wall of the second limit through hole 17.

After the liquid or gas detection is completed by the liquid detection mechanism or the gas detection mechanism, the first telescopic rod 5, the second telescopic rod 6 and the third telescopic rod 7 are shortened respectively, so that the first telescopic rod 5 is retracted into the fixed seat 3, the second telescopic rod 6 is retracted into the first telescopic rod 5, and the third telescopic rod 7 is retracted into the second telescopic rod 6. After that, the hook 11 on the tension rope 10 is hooked on the corresponding hanging ring 9, and the first telescopic rod 5, the second telescopic rod 6 and the third telescopic rod 7 are fixed to the fixed seat 3 by the tension rope 10 to prevent the first telescopic rod 5, the second telescopic rod 6 and the third telescopic rod 7 from sliding when not in use.

[0075] Example 7
