Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection, in particular to an air tightness detection mechanism for a gas meter. Background Art

[0002] The gas meter has an automatic accumulation function, so that users who use natural gas or pipeline gas can easily know how much gas they have used, so that they can pay according to the cubic meters of gas consumed each month. After the gas meter is processed, it needs to undergo a series of tests, among which the air tightness test is particularly important, which is related to the interests of users and their personal safety. When testing the air tightness of the gas meter, an air tightness detector is usually used. However, when the existing air tightness detector is used, the display screen and control buttons are mostly directly exposed to the outside world, lacking corresponding protective structures, which makes it easy for the display screen and control buttons to be bumped when carried, which may cause damage and affect its normal use. Therefore, it is necessary to propose a gas meter air tightness detection mechanism. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] See also Figure 1 and Figure 2 After the gas meter is processed, it needs to undergo a series of inspections, among which air tightness inspection is particularly important, as it is related not only to the interests of users but also to their personal safety. When inspecting the air tightness of a gas meter, an air tightness detector is usually used. The utility model provides a technical solution: an air tightness inspection mechanism for a gas meter, comprising an air tightness detector body 1 for inspecting the air tightness of a gas meter, a display screen 2 being arranged on the front of the air tightness detector body 1, and a plurality of control buttons 3 being arranged on one side of the display screen 2. When in use, according to the inspection standard, relevant parameters such as preparation time, inflation time, balance time, inspection time, exhaust time, etc. are set by using the display screen 2 and the control buttons 3 in coordination, and then the gas meter is connected to the air tightness detector body 1 to conduct an air tightness inspection.

[0019] In this embodiment, please refer to Figure 1 and Figure 2 A protective component 4 for protecting the display screen 2 and the control button 3 is provided on the front of the airtight detector body 1.
