[0027] The side clamping frame 45 includes a U-shaped frame 451 and a clamping wheel frame;

[0028] The middle of the sealing end of the U-shaped frame 451 is fixed to the middle of the stand 43, and a clamping wheel frame is installed at each end of the U-shaped frame 451, and the two clamping wheel frames are symmetrically arranged;

[0029] The clamping wheel frame includes an obtuse-angle V-frame 452, a clamping wheel 453 and a clamping cylinder 454. The middle part of the obtuse-angle V-frame 452 is hinged at the end of the U-shaped frame 451. One end of the obtuse-angle V-frame 452 is rotatably mounted with multiple clamping wheels 453. The axis of the clamping wheel 453 is vertically arranged. The other end of the obtuse-angle V-frame 452 is hinged to the end of the piston rod of the clamping cylinder 454. The cylinder body of the clamping cylinder 454 is hinged on the U-shaped frame 451. The piston rod of the clamping cylinder 454 extends and retracts to control the clamping wheel 453 to move closer to or away from the opening center of the U-shaped frame 451.

[0030] The inner side of the U-shaped frame 451 of the side clamping frame 45 is attached with a clamping arm rubber plate 48 to avoid damage to the outer wall of the liquefied gas cylinder during the clamping and fixing process.

[0031] like Figure 2-3 As shown, the magic wrench 46 includes a rotating member 461, a pressing cylinder 462, a cover 463 and a movable rod 464;

[0032] The cylinder body of the downward pressure cylinder 462 is installed on the top cross frame 44 through a rotating part 461, and the piston rod of the downward pressure cylinder 462 is vertically downward and a hollow cylindrical cover body 463 with an open lower end is fixedly installed at the end, a partition is fixedly set in the middle of the inner cavity of the cover body 463 and a plurality of through holes are provided on the partition, and a movable rod 464 is slidably installed in each through hole, and a limit head is provided at the end of the movable rod 464 above the partition, so that the movable rod 464 can slide upward without descending to fall out of the partition.

[0033] The magic wrench 46 used in the utility model is mainly suitable for angle valve type liquefied gas cylinders (ie, the liquefied gas inlet pipe is arranged at a right angle to the valve).

[0034] A weighing platform 47 is installed on the base 41 , the roller frame 42 is fixedly installed on the weighing platform 47 , and a weight display and a weight reaching alarm corresponding to the weighing platform 47 are installed on the stand 43 .

[0035] The working process of this utility model is as follows:

[0036] When the empty liquefied gas cylinder is sent onto the roller frame 42 and placed in the center of the U-shaped frame 451 of the side clamping frame 45, the piston rod of the clamping cylinder 454 extends out, and the clamping wheel 453 is manipulated to approach the opening center of the U-shaped frame 451 through the obtuse V frame 452 until it is close to the outer wall of the liquefied gas cylinder. The clamping wheels 453 on both sides clamp and fix the liquefied gas cylinder.

[0037] The staff connects the filling gun to the filling port of the liquefied gas cylinder, and then extends the piston rod of the downward pressure cylinder 462 to make the cover body 463 cover the plum blossom-shaped valve of the liquefied gas cylinder. Part of the movable rod 464 shrinks to the upper side under the upward pressure of the plum blossom-shaped valve, and the remaining movable rods 464 surround the valve. The rotating member 641 controls the rotation of the downward pressure cylinder 462 and the cover body 463. The movable rods 464 surrounding the valve act as a wrench at this time, opening the valve, and the solenoid valve on the filling gun is started and liquefied gas can be filled into the liquefied gas cylinder. During this period, the weighing platform 47 weighs the total weight of the liquefied gas cylinder, and then feeds back to the system and displays it on the weight display. When a certain amount of liquefied gas is filled and reaches the system set standard, the weight reaches the standard alarm and the solenoid valve of the filling gun is closed. The rotating member 461 and the downward pressure cylinder 462 of the magic wrench 46 are reset in turn. The staff removes the filling gun, and a filling is completed.

[0038] The top surface of the cover body 463 is fixedly provided with an X-slide rail 465, and a first slider 466 is slidably mounted on the X-slide rail 465. A first return spring is installed between the two ends of the first slider 466 and the corresponding ends of the X-slide rail 465. The top surface of the first slider 466 is fixedly provided with a Y-slide rail 467, and a second slider 468 is slidably mounted on the Y-slide rail 467. A second return spring is installed between the two ends of the second slider 468 and the corresponding ends of the Y-slide rail 467. The combination of the above-mentioned slide rails and sliders provides fine-tuning space for the position of the liquefied gas cylinder valve in the cover body 463, and has a larger tolerance range for the position of the liquefied gas cylinder. When one filling is completed, the cover body 463 releases the valve, and the cover body 463 can return to the initial position under the action of the return spring.

[0039] The weighing platform 47 is covered with a stainless steel cover to protect the weighing platform 47 .

[0040] The top cross frame 44 is provided with a spring balancer for hanging a filling gun. The filling gun is hung on a hook of the spring balancer. The hanging height of the filling gun is adjusted by the spring balancer to make it convenient for the staff to use. The spring balancer is a prior art. As long as it can realize the hanging, hanging height adjustment and locking of the filling gun, it can be applied to the present utility model. Its specific structure is not limited in this application.
