Problems solved by technology

In this way, it is necessary to drill holes on the shell and install joint fixing parts (commonly known as aviation joints), so as to realize the fixing and sealing of the other end after the fixed joint is placed in the position of the shell hole. In the case of other fixing measures, it will retract and fall into the interior of the housing, making it impossible to install, or it will slip in the hole, making the fixed joint impossible or difficult to assemble

specific Embodiment 3

[0041] Specific as Figure 6 As shown, this embodiment is a specific measuring instrument, such as a gas meter, a water meter, etc. The gas meter can be a membrane gas meter or an electronic gas meter. Taking the electronic gas meter as an example, it includes an instrument housing , there are metering modules, valves, sensors and other components inside. These components need to be connected to the external control board with signal lines. In this way, it is necessary to open holes on the upper surface and use fixing parts (called aviation connectors in the industry) to connect the signal lines. To ensure the normal transmission of signals, a very high level of safety and airtightness is also required. In this embodiment, the instrument includes the self-positioning and fixing assembly in the above-mentioned scheme, and the bottom plate (or side plate) of the instrument case is equivalent to the fixed body 2, and the fixed part 1 is a fixed part arranged on the instrument cas...

Abstract

The invention relates to the technical field of assembling and fixing, in particular to a fixing assembly capable of achieving self-positioning fixing. The fixing assembly comprises a fixing piece anda fixing body, a fixing hole is formed in the fixing body, a positioning protrusion is arranged on the fixing piece, the fixing body is provided with a positioning groove corresponding to the positioning protrusion, the fixing body and the positioning groove have a matching state and a positioning state, the positioning protrusion is located on the inner side of the inner side face of the fixingbody in the matching state, and when the fixing piece is rotated, the positioning protrusion and the positioning groove are switched into the positioning state. According to the scheme, self-positioning can be achieved, retraction, slipping and shaft rotation are prevented, and the fixing assembly is convenient to assemble. Meanwhile, the invention discloses a metering instrument with the fixing assembly.

Description

technical field [0001] The invention relates to the technical field of assembly and fixing, in particular to a fixing assembly capable of self-positioning and fixing and a measuring instrument with the fixing assembly. Background technique [0002] Fixing parts (such as screws) are common fixing devices in people's daily life, and are widely used in all walks of life. For example, screw connections can be seen almost everywhere in the machinery manufacturing industry. Some fasteners fasten two objects together, and some fasteners fix themselves on an object. The common way is that a certain object is provided with a hole, and other locking parts (such as nuts, etc.) are used to lock the fixing part after passing through the hole. [0003] However, in existing practical applications, when the fixing part passes through the hole and locks the nut or other locking parts, when the nut is locked or fixed, the fixing part will retract or slip, making assembly inconvenient, and i...
