Description

Technical Field

[0001] This utility model relates to the field of gas filling scale technology, and in particular to an electronic filling and measuring device. Background Technology

[0002] A gas filling scale is a precise weighing device used to measure the weight of gases. When in use, a gas filling scale ensures the accuracy and consistency of the gas filling in each cylinder by weighing the mass of the gas inside. Therefore, gas filling scales are widely used in industries such as chemical, pharmaceutical, and food and beverage.

[0003] Currently, gas filling scales are generally divided into two types: one is fixed to the ground by contact with foot pads or stands, and the other is embedded in the ground. Although these two types of gas filling scales can weigh the gas during the gas filling process, they are not easy to move. When using them, the gas cylinder and gas source can only be moved to the vicinity of the gas filling scale for filling, which is very inconvenient. Therefore, it is necessary to design a gas filling scale that is easy to move and carry.

Detailed Implementation

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example:

[0030] like Figure 1 , Figure 4 As shown, in order to solve the above problems, this embodiment discloses an electronic filling and measuring device, including a filling scale body and a moving component. The moving component includes a mounting plate 100 and a plurality of casters 101. The plurality of casters 101 are fitted at the bottom of the mounting plate 100. A push part 102 is provided on one side of the mounting plate 100. The push part 102 is detachably connected to the mounting plate 100.

[0031] The main body of the filling scale includes a high-precision pressure sensor 200, a placement part 201, a control platform 202, and a solenoid valve 203. The bottom of the mounting plate 100 is provided with a mounting groove 103. The high-precision pressure sensor 200 is placed in the mounting groove 103. The placement part 201 is placed on top of the high-precision pressure sensor 200, and one end is located in the mounting groove 103. The placement part 201 is slidably connected to the mounting groove 103.

[0032] Mounting plate 100 is provided with mounting arm 104, which is located on one side of placement part 201. One end of mounting arm 104 is detachably connected to mounting plate 100, and control platform 202 is located at the other end of mounting arm 104. Support frame 105 is provided on one side of mounting arm 104. One end of support frame 105 is detachably connected to mounting plate 100, and the other end is detachably connected to mounting arm 104. Solenoid valve 203 is located on support frame 105.

[0033] This invention enables the main body of the filling scale to be movable by incorporating a movable component. When movement is required, simply push the pusher 102 to rotate the casters 101, thus moving the main body of the filling scale. When it needs to be taken out, the pusher 102, mounting arm 104, and support frame 105 can be disassembled for easy carrying. Compared with traditional filling scales, this invention has the advantages of being easy to move and carry, solving the problem of current gas filling scales being inconvenient to move and carry during use.

[0034] In the above embodiments, the control platform 202, the solenoid valve 203, and the high-precision pressure sensor 200 can all adopt existing technologies.

[0035] In the above embodiments, the shape of the placement part 201 can be set according to actual needs, generally in the form of a circle or a square, and the mounting groove 103 can be configured to cooperate with the placement part 201.

[0036] like Figure 2 As shown, in order to facilitate the installation and disassembly of the push-type part 102, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the push-type part 102 includes a connecting plate 106, a hand handle 107 and a pair of connecting arms 108. The connecting plate 106 is disposed at the end of the pair of connecting arms 108 and is fixedly connected to the pair of connecting arms 108. The hand handle 107 is disposed at the other end of the pair of connecting arms 108, and both ends of the hand handle 107 are fixedly connected to the pair of connecting arms 108 respectively. The connecting plate 106 is detachably connected to one side of the mounting plate 100 by bolts.

[0037] During use, the push-hand part 102 can be connected to or disassembled from the mounting plate 100 by removing the bolts, thus facilitating the installation and disassembly of the push-hand part 102.

[0038] like Figure 5 As shown, in order to facilitate the installation and disassembly of the mounting arm 104, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the mounting arm 104 has a mounting base plate 109 at one end and a mounting top plate 110 at the other end. The mounting base plate 109 and the mounting plate 100 are detachably connected by bolts, and the control platform 202 is set on the mounting top plate 110.

[0039] During use, the mounting arm 104 can be connected to or disassembled from the mounting plate 100 by removing the bolts, thus facilitating the installation and disassembly of the mounting arm 104.

[0040] like Figure 5As shown, in order to facilitate the installation and disassembly of the support frame 105, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the support frame 105 includes a vertical support arm 111 and a horizontal support arm 112. The bottom of the vertical support arm 111 is detachably connected to the mounting plate 100 by bolts, and the other end is fixedly connected to one end of the horizontal support arm 112. The other end of the horizontal support arm 112 is detachably connected to one side of the mounting arm 104 by bolts. A fixing plate 113 is provided on the horizontal support arm 112, and the solenoid valve 203 is provided on the fixing plate 113.

[0041] During use, the horizontal support arm 112 can be connected or disassembled with the mounting arm 104 by removing the bolts, and the vertical support arm 111 can also be connected or disassembled with the mounting plate 100, thus facilitating the installation and disassembly of the support frame 105.

[0042] like Figure 3 , Figure 4 As shown, this utility model is movable due to the inclusion of a movable component. To avoid the utility model easily shifting during gas filling and affecting the filling process, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that a brake assembly is provided on the mounting plate 100. The brake assembly is located between the mounting arm 104 and the placement part 201. The brake assembly includes a fixing sleeve 114, a rotating screw 115, a brake disc 116, and a rotating part 117. The fixing sleeve 114 is provided on the mounting plate 100. The fixing sleeve 114 and the mounting plate 100 are provided with threaded holes that cooperate with the rotating screw 115. One end of the rotating screw 115 extends through the threaded hole to the bottom of the mounting plate 100 and is threadedly connected to the threaded hole. The brake disc 116 is located at the end of the rotating screw 115 at the bottom of the mounting plate 100 and is fixedly connected to the rotating screw 115. The rotating part 117 is located at the other end of the rotating screw 115 and is fixedly connected to the rotating screw 115.

[0043] The brake disc 116 has a rubber pad 118 at its bottom, which is detachably connected to the brake disc 116. The bottom of the rubber pad 118 has several protrusions.

[0044] In use, the rotating part 117 can be driven by hand, which in turn moves the rotating screw 115 downward, which in turn moves the brake disc 116 downward, causing the rubber pad 118 at the bottom of the brake disc 116 to contact the ground. This allows the present invention to be fixed by friction, thus avoiding the problem of the present invention easily moving during the gas filling process and affecting the filling process.

[0045] like Figures 3 to 5As shown, in order to avoid the gas cylinder from tipping over and colliding with the ground or equipment, which could lead to damage to the gas cylinder or even safety hazards, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the mounting plate 100 is provided with a limiting component, which includes a pair of limiting parts 119. The pair of limiting parts 119 are respectively disposed on both sides of the placement part 201 and are detachably connected to the mounting plate 100. The pair of limiting parts 119 are used to limit the gas cylinder.

[0046] The limiting part 119 includes a bottom mounting block 120, a top mounting block 121, a sliding mounting block 122, and a pair of sliding rods 123. The pair of sliding rods 123 are disposed between the bottom mounting block 120 and the top mounting block 121. One end of the pair of sliding rods 123 is fixedly connected to the bottom mounting block 120, and the other end is fixedly connected to the top mounting block 121. The sliding mounting block 122 is disposed on the pair of sliding rods 123 and is slidably connected to the pair of sliding rods 123. The sliding mounting block 122 is provided with an elastic limiting member, which is used to limit the gas cylinder.

[0047] The elastic limiting component includes a limiting rod 124, an arc-shaped limiting block 125, and a spring 126. One end of the limiting rod 124 passes through the sliding mounting block 122 and is slidably connected to the sliding mounting block 122. The arc-shaped limiting block 125 is fixedly disposed at the end of the limiting rod 124 that passes through the sliding mounting block 122. A pulling block 127 is provided at the other end of the limiting rod 124. The spring 126 is sleeved on the limiting rod 124. One end of the spring 126 is connected to the sliding mounting block 122, and the other end is connected to the pulling block 127.

[0048] It should be noted that there is a gap between the arc-shaped limiting block 125 and the gas cylinder, and the arc-shaped limiting block 125 does not contact the gas cylinder when the gas cylinder is not tilted.

[0049] When in use, the gas cylinder is placed on the placement part 201. When the gas cylinder tipps over, it can contact the arc-shaped limiting block 125. Because of the spring 126, when the gas cylinder contacts the arc-shaped limiting block 125, a supporting force is generated to prevent the gas cylinder from continuing to tip over. This avoids the gas cylinder from tipping over and colliding with the ground or equipment, which could lead to damage to the gas cylinder or even safety hazards.

[0050] A further preferred embodiment is that the arc-shaped limiting block 125 has a flexible sponge pad at one end used to limit the gas cylinder. The flexible sponge pad can prevent the arc-shaped limiting block 125 from damaging the outside of the gas cylinder.

[0051] like Figure 1As shown, in order to facilitate the control of the gas filling amount, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the input end of the solenoid valve 203 can be connected to an external gas source, and the output end of the solenoid valve 203 is provided with a gas delivery hose 204. One end of the gas delivery hose 204 is connected to the output end of the solenoid valve 203, and the other end can be connected to the gas cylinder to be filled.

[0052] When in use, the solenoid valve 203 is designed to facilitate control of the gas filling volume, thereby ensuring the quality of the gas filled in each gas cylinder.

[0053] Working principle of this utility model:

[0054] This invention enables the main body of the filling scale to be movable by incorporating a movable component. When movement is required, simply push the pusher 102 to rotate the casters 101, thus moving the main body of the filling scale. When it needs to be taken out, the pusher 102, mounting arm 104, and support frame 105 can be disassembled for easy carrying. Compared with traditional filling scales, this invention has the advantages of being easy to move and carry.

[0055] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
