[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0036] The gas quantitative filling device according to the embodiment of the utility model will be described below with reference to the accompanying drawings.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a gas quantitative filling device comprises: a stable lifting mechanism 1, a weight sensor 2 is arranged below the stable lifting mechanism 1, a first cylinder 3 is arranged on the side of the weight sensor 2, and the stable lifting mechanism 1, the weight sensor 2 and the first cylinder 3 are respectively arranged on a bracket 4;

[0038] The stable lifting mechanism 1 includes: two pipe hoops 11, each of the two pipe hoops 11 is respectively provided with a first mounting seat 12, a second mounting seat 13 is provided below the first mounting seat 12, the first mounting seat 12 and the second mounting seat 13 are connected to the second cylinder 15 through two connecting rods 14, a slider 16 is provided on the second mounting seat 13, the slider 16 is slidably set on a slide rail 17, the slide rail 17 is connected to the bracket 4, and the movable end of the first cylinder 3 is connected to the slider 16.

[0039] Specifically, in the initial state, when the device is not started, the first mounting seat 12 of the stable lifting mechanism 1 is located directly above the second mounting seat 13, forming an initial static position.

[0040] During the preparation stage, the relevant staff starts the second cylinder 15 to extend it. This action prompts the first mounting seat 12 to move downward along a circular path through the linkage action of the connecting rod 14, with the second mounting seat 13 as the fulcrum, until it is flush with the second mounting seat 13, thereby entering the loading preparation state of the gas cylinder 8.

[0041] During the loading process, the relevant staff places the air bottle 8 between the two pipe clamps 11 and fixes it, and starts the second cylinder 15 to shorten it, thereby the first mounting seat 12 drives the gas bottle 8 to move in the opposite direction, that is, upward, and finally lifts the gas bottle to the central position of the filling device, ready to receive gas filling.

[0042] Subsequently, the first cylinder 3 is started to perform a shortening operation, and the slider 16 is forced to move downward along the slide rail 17, driving the entire stable lifting mechanism 1 and the gas cylinder 8 to descend together.

[0043] When descending to a predetermined position, the bottom of the gas cylinder 8 contacts the weight sensor 2, ensuring that the weight sensor 2 accurately reads the weight of the gas cylinder.

[0044] Then, during the inflation process, the operator closely monitors the real-time weight of the gas cylinder displayed by the weight sensor 2, and when the weight reaches the preset target value, the inflation is stopped immediately to ensure the accuracy of the filling amount.

[0045] Finally, during the unloading process, after the device is filled, the second cylinder 15 is started again to extend, so that the first mounting seat 12 and the second mounting seat 13 are flush with each other again, and the relevant staff can remove the gas cylinder 8 from the pipe clamp 11.

[0046] According to the gas quantitative filling device of the embodiment of the utility model, on the one hand, it can ensure that the gas filling amount is accurately controllable, avoid overfilling or underfilling, and improve the filling accuracy; on the other hand, it can realize efficient loading and unloading of gas cylinders and improve work efficiency.

[0047] It should be noted that there are two stable lifting mechanisms 1, which are arranged one above the other. The slider 16 in the upper stable lifting mechanism 1 is connected to the slider 16 in the lower stable lifting mechanism 1 through the main beam 5. The movable end of the first cylinder 3 is connected to the slider 16 in the lower stable lifting mechanism 1.

[0048] It should be noted that a panel 6 is provided on the upper portion of the weight sensor 2 .

[0049] Specifically, the provided panel 6 can prevent the bottom of the gas cylinder 8 from scratching the weight sensor 2 .

[0050] It should be noted that both ends of the connecting rod 14 and both ends of the second cylinder 15 are provided with diamond-shaped bearing seats 7 .

[0051] It should be noted that the bracket 4 is also provided with a display, a controller and a voltage-stabilized power supply.

[0052] It should be noted that the two pipe clamps 11 in the stable lifting mechanism 1 are connected by butterfly bolts.

[0053] To sum up, according to the gas quantitative filling device of the embodiment of the utility model, on the one hand, it can ensure that the gas filling amount is accurately controllable, avoid overfilling or underfilling, and improve the filling accuracy; on the other hand, it can realize efficient loading and unloading of gas cylinders and improve work efficiency.

[0054] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
