[0026] The utility model will be further explained in detail in combination with the drawings and embodiments, obviously, the described embodiments are only a part of the utility model's embodiments, not all the embodiments. In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of the utility model protection.

[0027] Referring to Figure 1 .

[0028] The utility model discloses a kind of canned gas leakage detection devices, including shell 1, vertical slidingly arranged in shell 1 and support seat 2 and the elastic member 3 between shell 1 and support seat 2, the elastic member 3 is used to push support seat 2 to the top of shell 1 movement, make support seat 2 always keep suspended state;

[0029] The support seat 2 is used to support the tank, and the indicating component 21 is provided on the support seat 2, which extends from the top of the shell 1 downward to the side of the shell 1, and moves up and down relative to the shell 1 together with the support seat 2.

[0030] The shell 1 is provided with a mark corresponding to the position of the indicating component 21 on the outside, which is used to cooperate with the indicating component 21 to display the current position of the support seat 2 relative to the shell 1.

[0031] In a specific implementation, the tank of the carbon dioxide fire extinguisher is placed in the support seat 2, and under the action of gravity, the support seat 2 moves downward in the shell 1 against the elastic force of the elastic member 3, and stops moving after moving to a certain height. At this time, the gravity of the tank is balanced with the elastic force of the elastic member 3. When the tank leaks, the weight of the tank becomes lighter, and the elastic force of the elastic member 3 pushes the support seat 2 upward. Since the indicating component 21 moves upward together with the support seat 2, the presence or absence of leakage of the tank can be determined by observing the position of the corresponding mark of the indicating component 21.

[0032] Preferably, the elastic member 3 is a spring. The spring can have various specifications to match tanks of different weights.

[0033] In the utility model, the inspector only needs to observe the position of the indicating component 21 relative to the mark to determine whether the tank leaks or not, without the need for time-consuming and laborious weighing detection, which is efficient, fast and labor-saving.

[0034] In an embodiment, the mark is a warning color band 11 with color provided on the outside of the shell 1. The indicating component 21 moves up and down relative to the shell 1 together with the support seat 2, and the warning color band 11 is shielded and exposed.

[0035] When the weight of the can body is qualified, the indicating part 21 covers the warning color band 11; when the weight of the can body is unqualified, the indicating part 21 moves upward together with the supporting seat 2, and the warning color band 11 is exposed. In this way, the inspector only needs to observe whether the warning color band 11 is exposed or not, and can determine whether the can body is qualified or not, and can make the determination more simply and quickly.

[0036] Preferably, the color of the warning color band 11 is red and has a certain width.

[0037] In an embodiment, the warning color band 11 is arranged around the shell, and the indicating part 21 also extends downward from the top of the shell to the periphery of the shell. In this way, no matter from which direction the inspector looks, the inspector can see, and the inspection of the inspector is further facilitated.

[0038] In an embodiment, the external shape of the indicating part 21 matches the external contour of the shell, and when covering the warning color band 11, the warning color band 11 can be completely covered. In this way, the warning color band 11 can be avoided from being seen from the side due to the angle, and the mistake can be avoided.

[0039] In an embodiment, the mark further comprises a regular color band 12, which is arranged below the warning color band 11; when the weight of the can body is qualified, the indicating part 21 covers the warning color band 11 and exposes the regular color band 12. In a specific implementation, the arrangement of the regular color band 12 can transmit information to the inspector that the can body is qualified, and when the indicating part 21 covers the regular color band 12, the information that the device is malfunctioning or does not match the current can body can be transmitted to the inspector; at the same time, the color bands of different colors are also conducive to monitoring the leakage of the can body through visual detection in the later period.

[0040] Preferably, the color of the regular color band 12 is green and has a certain width.

[0041] In an embodiment, the top of the shell 1 has an outwardly extending extension 13, and the bottom of the indicating part 21 has an inwardly extending extension 211, which cooperates with the extension 13 to prevent the supporting seat 2 from moving upward and separating from the shell 1. In this way, due to the large elastic force of the spring, by arranging the extension 211 and the extension 13, when the can body is not placed on the supporting seat 2, the supporting seat 2 is prevented from separating from the shell 1, and the integrity of the device is ensured.

[0042] Preferably, the indicating part 21 has a certain elasticity, and by bending outwardly, the extension 211 can pass over the extension 13, and the supporting seat 2 can separate from the shell 1.

[0043] In an embodiment, the middle part of the supporting seat 2 is provided with a convex part 22 matched with the bottom of the corresponding tank body.

[0044] In a specific implementation, taking a carbon dioxide fire extinguisher as an example, the bottom of the carbon dioxide fire extinguisher tank body has an inner concave groove (many tank bodies for storing compressed gas have), and the convex part 22 can be matched with the groove at the bottom of the tank body, further limiting the tank body, and improving the stability of the tank body in the supporting seat 2.

[0045] It should be pointed out that the "tank body" in the present application is not limited to the carbon dioxide fire extinguisher tank body, but can also be other tank bodies storing gas.

[0046] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

[0047] It should be noted that if the utility model embodiments involve directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.
