Abstract
The utility model discloses a screw thread formula manometer structure, including the table body and installation body, the table body including watch core and watchcase, the watch core be fixed in the watchcase inside, the watch core bottom is equipped with the link that runs through the watchcase bottom, link and installation body threaded connection, the watchcase top edge is equipped with the perspective piece that covers the watch core, perspective piece be convex lens. The utility model aims at providing a dismouting efficiency is higher, the comparatively convenient screw thread formula manometer structure of observation.
Description
Technical field
The utility model belongs to pressure valve field, field, particularly relates to a kind of screw-type pressure meter structure.
Background technology
At present, a kind of tensimeter on the market, its table body directly uses screw lock on body, but needs to be connected with the reliable of body by multiple screw guarantee owing to showing body, and therefore tensimeter dismounting length consuming time, reduces efficiency of assembling.Meanwhile, because tensimeter embeds body interior completely, tensimeter size limits by body dimension, makes tensimeter dial plate less than normal, is not easy to observe.
Utility model content
The utility model is to overcome above-mentioned deficiency of the prior art, provide a kind of dismounting efficiency higher, observe conveniently screw-type pressure meter structure.
To achieve these goals, the utility model is by the following technical solutions:
A kind of screw-type pressure meter structure, comprise table body and body is installed, described table body comprises watch core and watchcase, described watch core is fixed on watchcase inside, the link run through bottom watchcase is provided with bottom watch core, described link is threaded with installation body, and described watchcase coboundary is provided with the perspective piece covering watch core, and described perspective piece is convex lens.Like this, table body is threaded by the link of watch core with installation body, decrease amount of parts, simplify disassembly process, also the watchcase showing body is made to be separated with installation body, table body is no longer subject to the restriction of installing body dimension, can suitably do greatly, so that user observes to facilitate by watchcase and dial plate size.Perspective piece adopts convex lens, amplifies dial plate high scale line and scale value information, thus further facilitates observation.
As preferably, described perspective piece edge is provided with the joint end of one in the side near watch core, and described joint end is provided with the snap fit of outwardly convex, and described watchcase madial wall is provided with the stopper slot matched with snap fit.Can be coordinated with the stopper slot on watchcase madial wall easily by the snap fit of perspective piece joint end, only need buckle perspective piece during installation and can complete the location with watchcase, dismounting more for convenience.
As preferably, described watch core be provided with watchcase inner bottom part against limited step, described limited step is fixed with watchcase inner bottom part from inside to outside by attachment screw.Carry out spacing by limited step to watch core position, make fixing also more for convenience of watch core.
As preferably, described perspective piece is one side convex lens, and perspective piece is convex surface away from the one side of watch core.Utilize convex lens to the convergence effect of light and convex lens image-forming discipline, by focal length, the thickness of adjustment tensimeter perspective piece, and object distance, thus control the size of image distance and picture, reach the amplification effect of perspective piece to dial plate, thus person's observed reading easy to use.As an alternative, the two sides of described perspective piece is convex surface.
The beneficial effects of the utility model are: (1) manometric table body easy accessibility, improves production efficiency; (2) Watch with magnifier dial scale line and scale value, thus be convenient to observe; (3) watchcase is separated with installation body, and watchcase size is no longer subject to installing body dimension restriction.
