Description

Technical Field

[0001] The utility model relates to the technical field of natural gas flow meters, in particular to a natural gas flow meter. Background Art

[0002] As a high-quality energy and chemical raw material, natural gas measurement is increasingly valued by people, and a natural gas flow meter is a special instrument for measuring natural gas. Existing natural gas flow meters are usually installed on natural gas transportation pipelines to intermittently detect the gas in the pipeline.

[0003] In the patent document with application number CN202221986137.5, a natural gas flow meter is disclosed, which effectively solves the problem that "the existing natural gas flow meters have certain limitations during use. In order to avoid the natural gas flow meters occupying space and affecting people's use space, the natural gas flow meters are usually installed in corners. When people need to record according to the data in the natural gas flow meter, they need to bend over or lie down to see it, which is very inconvenient. Moreover, when people record the data in the natural gas flow meter, there is no support. When users record the test data, it is easy for them to write unclearly. Therefore, a natural gas flow meter is proposed to solve the above problems."

[0004] However, when adjusting the height of the display device, it is necessary to press the connection block first and then perform the adjustment operation. This operation method is obviously not convenient enough compared to the operation method of "directly pressing or lifting the display device to adjust its height".

[0005] Therefore, in order to further improve the natural gas flow meter, we propose a flow meter for natural gas. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a natural gas flow meter, which can more conveniently adjust the height of the display device when in use.

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0008] A natural gas flow meter, comprising an air intake steel pipe, a detection device and a display device, wherein the detection device is fixedly mounted on the top outer wall of the air intake steel pipe, the display device is mounted above the detection device, and also comprises an adjustable telescopic rod structure;

[0009] The adjustable telescopic rod structure includes a barrel rod, a movable inner rod and a positioning structure; the barrel rod is located on the upper side of the detection device, and the bottom end is fixedly connected to the detection device, the movable inner rod is movably arranged on the inner side of the barrel rod, and the movable inner rod after movement is fixed in the barrel rod by the positioning structure arranged on the barrel rod, and the top end of the movable inner rod is fixedly connected to the display device.

[0010] As an improvement, the positioning structure includes a slot box, a sawtooth block, a rack slot and a spring; the front side wall of the cylinder rod is integrally formed with a connected and outwardly protruding slot box, the sawtooth block is movably arranged inside the slot box, and the side facing away from the sawtooth surface is connected to the inner bottom of the slot box through a spring, and the front side of the movable inner rod is provided with a rack slot meshing with the sawtooth block. It is convenient to position and fix it with a certain force after moving on the movable inner rod.

[0011] As an improvement, the positioning structure further includes a handle screw; a screw hole is reserved on the front side wall of the slot box, and after the handle screw is threadedly connected into the screw hole, the end thereof abuts against the sawtooth block. When data needs to be recorded, the display device can be firmly fixed by tightening the handle screw, and then data recording can be performed.

[0012] As an improvement, the top of the display device forms a plane. The plane can be used as a support surface. When data needs to be recorded, paper or the like can be placed on the plane to conveniently record data.

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. When the present invention is in use, the height of the display device can be adjusted by directly lifting the display device upwards or directly pressing the display device downwards, and the adjustment operation is more convenient, thereby making it more convenient to view the data on the display device.

[0015] 2. When the present invention is in use, when it is necessary to record the data on the display device, the raised display device can be conveniently fixed by tightening the handle screws, and then the data recording work can be directly carried out on the top surface of the display device, which is easy to operate.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] A natural gas flow meter comprises an air intake steel pipe 1, a detection device 2 and a display device 3. The detection device 2 is fixedly mounted on the top outer wall of the air intake steel pipe 1, and the display device 3 is mounted above the detection device 2 through an adjustable telescopic rod structure. Specifically:

[0023] The adjustable telescopic rod structure includes a barrel rod 4, a movable inner rod 5, a slot box 6, a sawtooth block 7, a rack groove 8 and a spring 9; the barrel rod 4 is located on the upper side of the detection device 2, and the bottom end is fixedly connected to the detection device 2, the movable inner rod 5 is movably arranged on the inner side of the barrel rod 4, and the top end is fixedly connected to the display device 3. The front side wall of the barrel rod 4 is integrally formed with a connected and outwardly protruding slot box 6, the sawtooth block 7 is movably arranged on the inner side of the slot box 6, and the side facing away from the sawtooth surface is connected to the inner bottom of the slot box 6 through a spring 9, and the front side of the movable inner rod 5 is provided with a rack groove 8 meshing with the sawtooth block 7.

[0024] It is worth mentioning that the adjustable telescopic rod structure also includes a handle screw 10; a screw hole is reserved on the front side wall of the slot box 6, and after the handle screw 10 is threadedly connected into the screw hole, the end thereof abuts against the serrated block 7. A pair of springs 9 are provided, and are respectively located on the left and right sides of the handle screw 10.

[0025] The working principle of the adjustable telescopic rod structure is: through the elastic force of the spring 9, the sawtooth block 7 will be squeezed and thus closely attached to the front side of the movable inner rod 5, and then through the engagement of the sawtooth block 7 with the rack groove 8, the movable inner rod 5 can be fixed with a certain force. (Note that data cannot be recorded on the plane 11 at this time)

[0026] As an embodiment, the top of the display device 3 forms a plane 11 .

[0027] During the specific implementation of this embodiment: the height of the display device 11 can be adjusted by directly lifting it upwards (be careful not to use excessive force, which may easily cause the movable inner rod 5 to separate from the tube rod 4), and then the data on the display device 11 can be conveniently viewed. When data needs to be recorded, the handle screw 10 needs to be tightened again, so that the display device 11 can be fixed, and then the data can be recorded on the plane 11. If data recording is not required, there is no need to adjust the handle screw 10.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
