Description
Technical field
The utility model belongs to water meter field, more particularly, to a kind of valveless water meter housing.
Background technology
Measure the growing of market with water, the consumption demand of civilian valveless water meter product rapidly increases.Because by work(
The restriction of energy, cost and use environment, the profile of domestic valveless base table has continued to use original structure substantially, as shown in Figure 4 and Figure 5,
Valveless base table includes watchcase a and the watch glasses b made of copper being threaded in above this watchcase a, is provided with lead seal hole in watchcase a, does not have
Fixing screw hole.Because watch glasses made of copper exposes outside, not only have impact on the attractive in appearance of valveless base table so as to seem and old-fashioned machine
Tool table is as good as, and reduces the class of whole table body, also can make the steam directly contact of watch glasses and in the air, accelerated corrosion effect.
For this reason, recent years, Ge great water meter manufacturing company will have attractive in appearance or functional characteristic structural shell based on fixation on valveless base table
The difficult problem that body solves as emphasis.
Some water meter manufacturing companies propose base table profile is modified, by increase screw hole and corresponding mounting platform
Fixed shell, but through initial estimate, material that base table is brought because of its weight and profile variation, processing cost rise larger,
Product price competition is caused to be in a disadvantageous position, stockpiling of unsold product.Therefore, in order to not change base table contour structures, existing producer is all
A directly shell in the outer cup of base table watch glasses, as shown in Figure 4 and Figure 5, this shell c is opened using corresponding with watch glasses b
Ring structure, shell c covers on watch glasses b and is threaded connection part and locks two ends, controls shell c to be tightened on watch glasses b.
The shortcoming of above-mentioned shell mechanism is：
1st, because shell and watch glasses processing always there are error, both abutted surfaces can not possibly be completely superposed, using screw thread
The upper and lower, phenomenon of double swerve inevitably occurs after connector is fixing, cause shell and watch glasses gouging abrasion, impact makes
Use the life-span；
2nd, the sound that collision rift sends can cause the illusion of product defect, impact integrated marketing and producer's sound to user
Reputation；
3rd, the assembling being completed by screw threads for fastening, process is loaded down with trivial details, wastes time and energy, and for ensureing the quick of screw threads for fastening, it is joined
The connecting hole of set is required for being accurately positioned, and the therefore requirement to shell processing and manufacturing is big, high cost.

The upper surface of valveless base table is provided with a heavy platform, and on described, lid inside lower end face is provided with downwardly projecting rib, this rib interior
Side connect with heavy platform side on cover the radial positioning on valveless base table.
For the utility model can preferably adjust installation gap and prevent assembling when occur rocking abrasion, on described lid with
Between the axial direction of valveless base table, packing ring is installed.
On described, the bottom surrounding of lid is uniformly provided with some buckles, is provided with draw-in groove with each buckle corresponding position on base,
Described upper lid is connected in draw-in groove by buckle and is packed on base.
For accurate positioning of the present utility model, processing is simple and ensures not to be disassembled, on the base below described draw-in groove
It is provided with the positioning hole connecting with draw-in groove, in this positioning in the hole, lead sealing is installed, the bottom connection of the upper end of this lead sealing and buckle is used
In the upper axially position covered on valveless base table.
Described lead sealing and positioning hole adopt interference fit.
Equipped with transparency window on described observation panel.
Described lead sealing is using the U-shaped being adapted with buckle bottom.
The junction of described buckle and draw-in groove adopts right angle.
The utility model by clamping, upper lid is arranged on valveless base table, using the access section pair of upper lid and valveless base table
Upper lid carry out up and down, left and right positioning, can effectively eliminate the scale error occurring because of upper lid with the processing of valveless base table it is ensured that water
The service life of table；Directly clamping assembling, process is simple, and time saving and energy saving, requirement on machining accuracy is not high, fabricates low cost.
The utility model structure is simple, can realize precise positioning, installation under conditions of not changing base table self structure, whole assembling
Process does not need using any screw and any instrument, convenient use, greatly reduces actual production, assembling man-hour, is suitable for
In civilian valveless water meter product.
