[0002] Gas metering is the determination and recording of the amount of gas passing through the pipeline. The device for measuring gas is called a gas meter or gas flow meter, which is used to accumulate the volume or mass of gas passing through the pipeline. Some flow meters only measure the amount of gas passing through per unit time, and must pass through a conversion mechanism to display the accumulated amount. Since gas metering is easily affected by temperature and pressure, a temperature and pressure compensation device can be attached to the metering device.

[0003] The existing gas metering shell is generally fixed at a designated location by multiple sets of bolts. In actual use, when the gas metering device and the shell need to be disassembled for maintenance, the staff is required to loosen the multiple sets of bolts, which is cumbersome to operate. In addition, as the use time increases, the bolts may rust, which further increases the difficulty of disassembling and assembling the gas metering shell and reduces the practicality of the existing gas metering shell.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a technical solution: a gas metering shell that is easy to disassemble and assemble, comprising a shell body 1, a mounting plate 2 is fixed to the outside of the shell body 1, a display screen 3 is fixed to the front of the shell body 1, a mounting assembly 200 for mounting the shell body 1 is installed on the top of the mounting plate 2, and a reinforcement assembly 300 for making the shell body 1 more stably fixed is installed inside the shell body 1;

[0025] Through the coordinated use of the shell body 1, the mounting plate 2, the mounting assembly 200 and the reinforcement assembly 300, in actual use, when the gas metering device together with the shell needs to be disassembled for maintenance, the gas metering shell can be removed more conveniently, and after the maintenance is completed, the gas metering shell can be installed conveniently and effectively, avoiding the situation where the bolts are fixed by rust, thereby increasing the difficulty of disassembling and assembling the gas metering shell. The operation is relatively simple, which improves the practicality of the gas metering shell that is easy to disassemble and assemble.

[0026] In this embodiment, the installation assembly 200 is a structure for installing the gas metering housing.

[0027] like Figure 1 and Figure 2As shown, the mounting assembly 200 includes two fixed frames 201 fixed on the top of the mounting plate 2, the fixed frames 201 are internally slidably connected with a movable plate 202, the top of the movable plate 202 is fixed with a spring 203, the inside of the movable plate 202 is fixed with a fixed rod 204, the top of the fixed rod 204 is fixed with an adjustment block 205, and the top of the mounting plate 2 is provided with two through holes 206.

[0028] It should be noted that two connectors 4 are fixed on the top of the shell body 1 to ensure that the shell body 1 is connected to the gas pipeline through the connectors 4. The outer side of the connector 4 is threadedly connected with a protective cover 5 to protect the connector 4 when not in use.

[0029] In addition, the top of the spring 203 is fixed to the inner top wall of the fixed frame 201 to fix the spring 203 to ensure that the spring 203 can play the expected elastic effect. The diameter of the adjustment block 205 is larger than the diameter of the fixed rod 204, which makes it convenient to pull the fixed rod 204 through the adjustment block 205.

[0030] In addition, the bottom end of the fixing rod 204 passes through the fixing frame 201 , the movable plate 202 and the through hole 206 in sequence and extends to the bottom of the mounting plate 2 , ensuring that the housing body 1 can be preliminarily fixed by the fixing rod 204 .

[0031] At the same time, the length of the movable plate 202 is equal to the length inside the fixed frame 201, and the width of the movable plate 202 is equal to the width inside the fixed frame 201, so that the movable plate 202 moves more stably in the fixed frame 201, so that the movable plate 202 can better squeeze the spring 203.

[0032] In this embodiment, the reinforcement assembly 300 is a structure that makes the gas metering housing more stably installed.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the reinforcement component 300 includes two fixed cylinders 301 respectively fixed on the left and right sides of the mounting plate 2, the interior of the fixed cylinder 301 is slidably connected with a plug-in rod 302, the two plug-in rods 302 are fixed with an adjustment frame 303 at the opposite ends, the two adjustment frames 303 are fixed with a fixing ring 304 on the opposite sides and the two fixing frames 201 are fixed with an elastic rope 305 between the outer sides of the two fixing rings 304 on the left and between the outer sides of the two fixing rings 304 on the right, and two plug-in cavities 306 are opened inside the mounting plate 2.

[0034] It should be noted that the adjusting frame 303 is threadedly connected to the fixing tube 301 , so that the adjusting frame 303 is fixed more stably. The inner diameter of the fixing tube 301 is equal to the diameter of the plug-in rod 302 , so that the plug-in rod 302 slides more stably in the fixing tube 301 .

[0035] In addition, the plug-in cavity 306 is connected to the through hole 206, and the opposite ends of the two plug-in rods 302 successively penetrate the mounting plate 2, the through hole 206, the fixing rod 204 and the plug-in cavity 306 and extend to the interior of the plug-in cavity 306 to be plugged with the plug-in cavity 306, ensuring that the plug-in rod 302 can penetrate the fixing rod 204 and be plugged with the plug-in cavity 306, thereby further fixing the fixing rod 204, thereby achieving the effect of further fixing the shell body 1.

[0036] The working principle of the above embodiment is:

[0037] When in use, when the shell body 1 needs to be installed, the two adjusting frames 303 are rotated respectively to separate the adjusting frames 303 from the fixing cylinder 301, thereby pulling the plug-in rod 302 out of the mounting plate 2, and then pulling the adjusting block 205 upward, thereby driving the movable plate 202 and the fixing rod 204 to move up and down, thereby separating the fixing rod 204 from the through hole 206. At this time, the spring 203 is in a compressed state. When the shell body 1 is moved to the location where it needs to be fixed, the adjusting block 205 is released, and under the action of the restoring elastic force of the spring 203, the fixing rod 204 is re-passed through the through hole 206 and plugged into the structure of the target location, thereby preliminarily fixing the shell body 1, and then the plug-in rod 302 is re-plugged into the plug-in cavity 306, and then the adjusting frame 303 is rotated to make the adjusting frame 303 threadedly connected to the fixing cylinder 301, thereby fixing the plug-in rod 302, thereby further improving the stability of the installation of the shell body 1.

[0038] Compared with the prior art, the gas metering shell that is easy to disassemble and assemble, through the coordinated use of the shell body 1, the mounting plate 2, the mounting assembly 200 and the reinforcement assembly 300, can conveniently remove the gas metering shell when it is necessary to disassemble and maintain the gas metering device together with the shell during actual use, and can also conveniently and effectively install the gas metering shell after the maintenance is completed, thereby avoiding the situation in which the gas metering shell is fixed by bolts and the bolts are rusted, thereby increasing the difficulty of disassembling and assembling the gas metering shell. The operation is relatively simple, which improves the practicality of the gas metering shell that is easy to disassemble and assemble, and solves the problem of low practicality of the existing gas metering shell.
