DETAILED DESCRIPTION

[0022] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] A weighing device for a carbon dioxide cylinder, such as Figures 1 - 5 As shown, it includes a weighing pan 1, a weighing sensor 2 arranged on the weighing pan 1, and an output component 3 electrically connected to the weighing sensor 2.

[0024] The limiting assembly includes three first limiting members 4 and one second limiting member 5, the three first limiting members 4 are distributed in a triangular shape, and two of the first limiting members 4 are symmetrically arranged at both ends of the weighing sensor 2, the cross-sections of the first limiting members 4 and the second limiting members 5 are both L-shaped, and the three first limiting members 4 and the one second limiting member 5 are arranged around the weighing sensor 2, the three first limiting members 4 are detachably connected to the top of the weighing pan 1 by bolts, the carbon dioxide cylinder is placed between the three first limiting members 4 and the one second limiting member 5, the end of the first limiting member 4 facing the material is provided with an extrusion portion 41 extending obliquely toward the material in a vertical direction, the first limiting member 4 and the second limiting member 5 are both made of elastic material, and the extrusion portion 41 It has elastic deformation potential energy for squeezing toward the outer peripheral wall of the material. When the carbon dioxide cylinder is placed between three first limit pieces 4 and one second limit piece 5, the extrusion portion 41 contacts the carbon dioxide cylinder and squeezes the outer peripheral wall of the carbon dioxide cylinder, so that the carbon dioxide cylinder is relatively fixed between the three first limit pieces 4; and the shortest distance between two symmetrical first limit pieces 4 is smaller than the diameter of the carbon dioxide cylinder, so that the carbon dioxide cylinder cannot be placed between the three first limit pieces 4 in the vertical direction. Since the outer peripheral wall of the carbon dioxide cylinder is arc-shaped, it has a good guiding effect when it is placed between the three first limit pieces 4 in the horizontal direction, so that the extrusion portion 41 can be deformed by external force.

[0025] A symmetrically arranged shaft seat 11 is fixedly connected to the top of the weighing pan 1 near the side wall, and a rotating shaft 51 is fixedly connected to the second limiting member 5. The rotating shaft 51 is rotatably connected to the shaft seat 11 by means of a shaft hole. The second limiting member 5 is rotatably connected to the top of the weighing pan 1 by means of a shaft hole, so that the second limiting member 5 can be rotated away from the three first limiting members 4, so that the carbon dioxide cylinder can be placed in more conveniently. A groove 7 is provided on the side wall of the top of the weighing pan 1, so as to ensure the rotational freedom of the second limiting member 5. A magnetic member 71 is fixedly connected to the groove 7. The cross-section of the magnetic member 71 is L-shaped and fits with the inner wall of the groove 7. When the second limiting member 5 rotates toward the direction of the first limiting member 4 until it fits with the side wall of the weighing pan 1, the magnetic member 71 can adsorb the second limiting member 5 to prevent the second limiting member 5 from shaking and rotating when the carbon dioxide cylinder is placed, thereby affecting the placement of the carbon dioxide cylinder.

[0026] The weighing pan 1 is provided with a limit pin 6 for limiting the second limit member 5 from being away from the weighing pan 1, the weighing pan 1 is provided with a limit hole 12 for the limit pin 6 to pass through, the second limit member 5 is provided with a through hole 52 for the limit pin 6 to pass through, the limit block is fixedly connected to the outer peripheral wall of the bottom end of the limit pin 6, the inner wall of the limit hole 12 is provided with a through groove 121 for the limit block to pass through, the top of the limit pin 6 is fixedly connected with a resistance part 63, the diameter of the resistance part 63 is larger than the diameter of the through hole 52, and a plurality of elastic members 62 are distributed in an array on the outer peripheral wall of the limit pin 6, the elastic member 62 has the elastic deformation performance of continuously resisting the inner wall of the limit hole 12, and the elastic member 62 is hemispherical; the limit pin 6 is provided, and when the second limit member 5 rotates close to the first limit member 4, the bottom of the second limit member 5 is in contact with the top of the weighing pan 1 When the parts are fitted, the limit pin 6 is passed through the limit hole 12 on the weighing disc 1 along the through hole 52 on the second limit piece 5, and the limit block is aligned with the through slot 121, so that the limit pin 6 passes through the limit hole 12 smoothly and the positioning block 61 passes through the through slot 121. When the positioning block 61 passes through the through slot 121, the abutment 63 abuts against the second limit piece 5. At this time, the limit pin 6 is rotated to make the positioning block 61 away from the through slot 121, so that the positioning block 61 is used to limit the limit pin 6 from leaving the weighing disc 1; and the elastic members 62 distributed in an array on the outer peripheral wall of the limit pin 6 continuously abut against the outer peripheral wall of the limit hole 12, thereby increasing the friction between the limit pin 6 and the inner wall of the limit hole 12, so that the limit pin 6 is fixed at the corresponding position, thereby enabling the second limit piece 5 to be fixed at the corresponding position.

[0027] Working principle: when the carbon dioxide gas cylinder needs to be installed, the limit pin 6 is pulled out, and the second limit piece 5 can be rotated and away from the three first limit pieces 4. At this time, the carbon dioxide gas cylinder can be smoothly placed from the second limit piece 5 to the three first limit pieces 4, and the outer peripheral wall of the carbon dioxide gas cylinder is squeezed by the elasticity of the extrusion part 41 on the first limit piece 4, so as to support the carbon dioxide gas cylinder in the corresponding position. When the placement is completed, the second limit piece 5 is rotated close to the first limit piece 4 until the bottom of the second limit piece 5 is in contact with the top of the weighing pan 1, and then the limit pin 6 is passed through the limit hole 12 on the weighing pan 1 along the through hole 52 on the second limit piece 5, and the limit block is aligned with the through groove 121, so that the limit pin 6 passes through the limit hole 12 smoothly and the positioning block 61 passes through the through groove 121. After the positioning block 61 passes through the through slot 121, the abutment portion 63 abuts against the second limiting member 5. At this time, the limiting pin 6 is rotated to make the positioning block 61 move away from the through slot 121, thereby utilizing the positioning block 61 to limit the limiting pin 6 from leaving the weighing plate 1; and the elastic members 62 distributed in an array on the outer peripheral wall of the limiting pin 6 continuously abut against the outer peripheral wall of the limiting hole 12, thereby increasing the friction between the limiting pin 6 and the inner wall of the limiting hole 12, so that the limiting pin 6 is fixed at a corresponding position, thereby enabling the second limiting member 5 to be fixed at a corresponding position, and utilizing the cooperation of the second limiting member 5 and the three first limiting members 4 to fix the carbon dioxide gas cylinder at a corresponding position, thereby ensuring that the carbon dioxide gas cylinder is always located directly above the weighing sensor 2, and preventing the carbon dioxide gas cylinder from shaking, causing the position of the carbon dioxide gas cylinder and the weighing sensor 2 to deviate, thereby affecting the weighing accuracy;

[0028] An output component 3 is also provided, and the output component 3 includes a display device and an alarm device arranged in the display device. The display device can display the weight of the carbon dioxide cylinder in real time to judge the carbon dioxide capacity inside the carbon dioxide cylinder.
