Abstract
The applied invention discloses a shell and a metering instrument comprising the same; the shell is provided with a turning cover structure and internally comprises a mortise structure. The invention solves the technical problem of the appearance defect of a product caused in the processes of opening, closing and turning the shell, seamless closing of the appearance is ensured, and the smooth turning effect is achieved. The shell is suitable for the product with a turning cover, particularly the metering instrument with the turning cover.
Description
Technical field
The present invention relates to a kind of shell, the measuring instrument that relates in particular to a kind of shell of metering field and comprise this shell.
Background technology
At present, the shell of measuring instrument upset mostly is concentric shafts upset, causes shell or renovate surface jagged, or the gap of mating surface is excessive, cannot accomplish smooth combination, product appearance is produced to significant impact, as shown in Figure 1.Along with the development in epoch and social progress, people improve gradually to the appearance requirement of product, and product is also taken seriously day by day to people's first impression.
Tradition upset mode or have very large fillet at turning part and shell junction, in order that renovate the process from closure state to rotation, renovate not can with on be stamped interference, but, can make like this both sides jagged, to the globality of product surface, destroy very large, and, the housing of both sides is comparatively weak, causes the insufficient strength of shell, easily extruding.At present, the open defect that traditional upset mode is brought has not been well positioned to meet the requirement in market, in the urgent need to a kind of new innovation and creation, overcomes this defect.
Summary of the invention
The invention solves and renovate opening, cause that product appearance exists the technical matters of defect in closed, switching process, reach and both guarantee the seamless closure of outward appearance, the effect that can overturn smoothly again.
In order to solve above-mentioned technical matters, the present invention has designed a kind of tenon groove structure, this tenon groove structure is positioned on a shell, this shell comprises a upper cover, and this upper cover has a tenon structure, such as rotation axis etc., this shell also comprises that one is renovated, this is renovated has a groove structure, and described upper cover links together with renovating by above-mentioned tenon structure and groove structure, realizes the function of upset.In order to make to renovate, can rotate smoothly, and when closure, renovate with upper cover and can realize seamless link, it is seamless that this seamless link not only looks over from front, if pass by from the side also seamless, need again to renovate with upper cover and can not produce interference simultaneously in rotary course, this just further requires to renovate and can rotate on one side, recess upper cover on one side, for this reason, renovate with upper cover and should at least there is a tongue-and-groove movable device, can effectively limit the movement locus of renovating in switching process, in tongue-and-groove movable device, there is tenon structure and a groove structure, this tenon structure can be column construction, this groove structure is guiding groove, make the advance and retreat of flip-top cap assembly guide recess structure in switching process.In order to facilitate the installation of tenon groove structure, renovating, be divided into two independent parts, renovate upper plate and renovate lower plate, when assembling, first will renovate upper plate and be installed to turning axle cooperation position, the lower plate of renovating of again another being matched is with it attached to the relevant position of renovating upper plate, stamps screw and fixes, then stamp the plastic cap with tamper function.
Some common apparatus all can have a shell, and normal with the structure of renovating on shell, above-mentioned can perform well on these shells with renovating of tenon groove structure.For measuring instrument, it generally includes a upper cover, and a lower cover is renovated for one, a battery cover, and an electronic module, such as water meter, heat energy meter, gas meter, flow meter, also can include a base table for fluid metering instrument.On these measuring instruments, use above-mentionedly with the renovating of tenon groove structure, can make well upper cover, renovate seamless connection, coordinate perfect mouthful, and make to renovate and can overturn smoothly along turning axle.Except measuring instrument, mobile communication terminal, such as mobile phone, also can apply above-mentioned flip structure.
Renovate with upper cover and should at least there is a tongue-and-groove movable device, effectively limit and renovate the movement locus in switching process, meanwhile, in tongue-and-groove movable device, should there is convex hull locating structure, make to renovate in the process of 0 ~ 90 ° of upset and can not rock easily (see figure 4).
Renovating top should have raised ribs position, makes to renovate in closing course to play the guiding role, and gets back to initial state (seeing Fig. 2 and Fig. 5), and closely cooperates with notching construction, realizes and under External Force Acting, not to rock and to overturn not being subject to.
The present invention has changed the pattern of traditional flip lid rotary mechanism, accomplishes intact cooperation between each part of product, without any outward appearance breach and outer cover intensity hidden danger, makes product appearance there is no flaw, and product quality is more perfect.The elasticity of utilizing meter sheathing material self to possess, in switching process, can have good upset feel and effect, can embody well the high-end quality characteristic of product.
