Abstract
The utility model discloses a natural gas watchcase mounting, including last watchcase and lower watchcase, and set up in last watchcase fixed strip on the watchcase under with, go up watchcase bottom and watchcase top down respectively an organic whole has made to extend the ring sum under and has encircled, it has a plurality of archs to go up to extend the ring upside and extend the interval suppression of ring downside down, the fixed strip has first semi -ring fixed strip and second semi -ring fixed strip to constitute, the caulking groove has been seted up at first semi -ring fixed strip and second semi -ring fixed strip middle part, the upside and the suppression of downside interval of caulking groove have a plurality of and protruding complex notch, first semi -ring fixed strip and second semi -ring fixed strip fixed mounting, the utility model discloses a natural gas watchcase mounting installs in the last watchcase and the lower watchcase outside through the fixed strip, has formed horizontal fixedly, carries out the gomphosis through protruding and notch after that, has formed fore -and -aft installation, and the fixed strip is assembled by first semi -ring fixed strip and second semi -ring fixed strip and is constituted, and the installation is simple, convenient to use.
Description
Technical field
The utility model relates to a kind of gas meter shell component, particularly rock gas watchcase fixture, belongs to gas meter shell technology field.
Background technology
Existing gas meter, flow meter watchcase mainly contains two kinds of materials and iron-clad and aluminum hull, and profile has large shell table and little shell table two kind; Little aluminum hull profile, compact conformation, good looking appearance; Cutoff board is had to make coal gas moisture content and impurity directly not flow to slide valve system in the fuel gas inlet pipe of large watchcase, its large shell has the effect of buffering flow velocity and the moisture content held in manufactured gas, manufactured fuel gas and impurity simultaneously, make the drive disk assemblies such as air chamber sealing layer segment, guiding valve not by water and contaminating erosion, thus ensure sealing and metering effect; Large watchcase is generally fixed by a collar bolt by upper watchcase and lower watchcase, and just undertaken common fixing between upper watchcase of the prior art and lower watchcase by bolt, both connect undertighten, easily cause inside watchcase by water and contaminating erosion.
Summary of the invention
(1) technical matters that will solve
For solving the problem, the utility model proposes rock gas watchcase fixture, installation process is fairly simple, improves the sealing of watchcase and lower watchcase.
(2) technical scheme
Rock gas watchcase fixture of the present utility model, comprises watchcase and lower watchcase, and is arranged at the fixed strip on watchcase and lower watchcase; Extended loop and downward-extension ring has not been made into integration with lower watchcase top portion bottom described upper watchcase; Interval is suppressed with multiple projection on the upside of described upper extended loop and on the downside of downward-extension ring; Described fixed strip has the first semi-ring fixed strip and the second semi-ring fixed strip to form; Caulking groove is offered in the middle part of described first semi-ring fixed strip and the second semi-ring fixed strip; The interval, the upper side and lower side of described caulking groove is suppressed with recess that is multiple and male cooperation; Described first semi-ring fixed strip and the fixed installation of the second semi-ring fixed strip.
Further, described upper extended loop and downward-extension ring are chimeric with caulking groove after fitting.
Further, described first semi-ring fixed strip and the second semi-ring fixed strip end are staircase structure; Described first semi-ring fixed strip and the second semi-ring fixed strip are bolted.
beneficial effect
Compared with prior art, rock gas watchcase fixture of the present utility model, be installed on outside upper watchcase and lower watchcase by fixed strip, define horizontal fixing, then be fitted together to by protruding and recess, define longitudinal installation, fixed strip is assembled by the first semi-ring fixed strip and the second semi-ring fixed strip and is formed, installation process is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is upper watchcase of the present utility model and lower meter casing structure schematic diagram;
Fig. 2 is fixed strip structural representation of the present utility model.
