Abstract
The utility model discloses a kind of improvement structures for solving seal failure, including fixed ring, watch crystal, main weldering wiring, auxiliary sealing wire and welding groove, fixed ring is weldingly fixed on watch crystal and forms O-ring slot, O-ring slot is sealed by O-ring, two main weldering wiring are provided in fixed ring, design has welding groove on watch crystal, and the boss of the two sides of welding groove is auxiliary sealing wire, and the height of sealing wire is assisted to be arranged lower than main weldering wiring.Original plastics watch crystal is split into two parts, respectively fixed ring and watch crystal by the utility model, forms O-ring slot in watch crystal side by welding together two parts, realizes product sealing for placing O-ring.
Description
Technical field
The utility model relates to a kind of sealing structures, and in particular to a kind of improvement structure for solving seal failure.
Background technique
The plastic table glass sides of coaxial water meter (single interface water meter) are provided with O-ring slot (shown in Fig. 1), at present using primary
The advantages of mode of injection molding produces, the production method is: moulding energy one-pass molding, with short production cycle.But because of its structure
Particularity O-ring slot in sealing surface on can have two parting lines, and as time goes by, the aging of mold, parting line
Meeting be more and more obvious and then influence the sealing effect of entire water meter.If removed by the way of manually repairing overlap after injection molding
Parting line may generate secondary injury to sealing surface, can not still eliminate hidden leakage defect.
In conclusion the utility model devises a kind of improvement structure for solving seal failure.
Summary of the invention
In view of the shortcomings of the prior art, solving changing for seal failure the utility model aims to provide a kind of
Into structure, original plastics watch crystal is split into two parts, respectively fixed ring and watch crystal, by welding two parts
It is connected together and forms O-ring slot in watch crystal side, realize product sealing for placing O-ring.
To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of solution sealing is lost
The improvement structure of effect, including fixed ring, watch crystal, main weldering wiring, auxiliary sealing wire and welding groove, fixed ring are welded and fixed
On watch crystal and O-ring slot is formed, O-ring slot is sealed by O-ring, is provided with two main weldering wiring, table glass in fixed ring
Design has welding groove on glass, and the boss of the two sides of welding groove is auxiliary sealing wire, assists the height of sealing wire lower than main weldering wiring
Setting.
Working principle of the utility model is: fixed ring is fixed on watch crystal by way of ultrasonic bonding.Fixed ring
Upper design has two main weldering wiring, and design has welding groove on watch crystal, and the boss of welding groove two sides is then auxiliary sealing wire,
Its height is slightly below main weldering wiring, and when ultrasonic bonding, main weldering wiring can be first solded into the welding groove on watch crystal, generates
Then a large amount of overlaps assist sealing wire that can just weld together with fixed ring, since the height of auxiliary sealing wire is slightly below main weldering
Wiring so the overlap generated after its welding is less, while can improve weld strength again and stop the welding overlap in welding groove
It overflows.
The utility model has the beneficial effects that
The watch crystal structure of original complexity has been split into two parts by the utility model, simplifies mould structure, is improved
The service life and reliability of mold, and the parting line on sealing surface is eliminated, eliminate parting line bring sealing hidden danger.
Detailed description of the invention
It is described in detail the utility model with reference to the accompanying drawings and detailed description；
Fig. 1 is the structural schematic diagram of the background technique of the utility model；
Fig. 2 is the schematic perspective view of the utility model；
Fig. 3 is the sectional side elevation of Fig. 2 of the utility model；
Fig. 4 is the portion the A enlarged diagram of Fig. 3.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Fig. 2-Fig. 4, present embodiment uses following technical scheme: a kind of improvement knot solving seal failure
Structure, including fixed ring 1, watch crystal 2, main weldering wiring 3, auxiliary sealing wire 4 and welding groove 5, fixed ring 1 are weldingly fixed on table
On glass 2 and O-ring slot is formed, O-ring slot is sealed by O-ring, is provided with two main weldering wiring 3, table glass in fixed ring 1
Design has welding groove 5 on glass 2, and the boss of the two sides of welding groove 5 is auxiliary sealing wire 4, and the height of auxiliary sealing wire 4 is lower than main weldering
Wiring 3 is arranged.
Original plastics watch crystal is split into two parts, respectively fixed ring 1 and watch crystal 2 by the utility model.It is logical
It crosses to weld together two parts and forms O-ring slot in watch crystal side, realize product sealing for placing O-ring.Production
When fixed ring 1 be fixed on by way of ultrasonic bonding on watch crystal 2.Design has two 3 main weldering wiring, table in fixed ring 1
Design has welding groove 5 on glass 2, and the boss of the two sides of welding groove 5 is then auxiliary sealing wire 4, and height is slightly below main weldering and connects
Line 3, when ultrasonic bonding, main weldering wiring 3 can be first solded into the welding groove 5 on watch crystal 2, generate a large amount of overlaps, then
Auxiliary sealing wire 4 can just weld together with fixed ring 1, since the height of auxiliary sealing wire 4 is slightly below main weldering wiring 3, so
The overlap that it is generated after welding is less, while can improve weld strength again and the welding overlap in welding groove 5 is stopped to overflow.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
