A kind of quick fixation structure of drain valve external connecting function component
Technical field
The present invention relates to a kind of quick fixation structure of drain valve, more particularly to a kind of fast-assembling knot of drain valve external connecting function component
Structure.
Background technology
Drain valve is the drainage arrangement for controlling cistern, some work(if desired are fixedly mounted in the top of drain valve
Can component realize the function of drain valve, it usually needs drain valve disassemble in water tank first come out, by functional unit with drain
Valve is packed into water tank by screw or after gluing and being fixed, then by black box, and installation steps are complicated, and efficiency is low.
Invention content
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of quick fixation structure of drain valve external connecting function component, first
Functional component is assembled in advance with quick assembling unit, when needing to install drain valve functional component additional, can realize Fast Installation, is solved
The problem of needing to disassemble entire drain valve when installation function component in background technology of having determined.
To achieve the goals above, the technical solution adopted by the present invention is as follows:
A kind of quick fixation structure of drain valve external connecting function component, including draining valve body, functional component and quick assembling unit.It is described
To have a boss, the quick assembling unit include shell and several elastic components for draining valve body upper end, the one of the shell
End is fixedly connected with functional component, and the other end opens up that there are one the mounting holes to match with the projection shape.The elastic component
Including integrally formed clamping block and elastic card claw, the clamping block is circumferentially laid along the mounting hole, the elastic card
Pawl is inwardly projecting relative to the wall surface of mounting hole.The shell is fitted to drain valve by the mounting hole and boss
On ontology and pass through the elastic card claw clamping fixed.
Further, one end of the elastic card claw is the fixing end being connect with clamping block, and the other end is free end, described
The free end of elastic card claw is obliquely installed upwards.
Further, the shell is evenly distributed the mounting groove for being used to install the elastic component equipped with several, institute
The clamping block two sides stated are respectively equipped with protrusion, the mounting groove both sides be equipped with the matched card slot of protrusion, it is described
Clamping block be fixedly mounted in the mounting groove with the interference fit of card slot by the protrusion.
Further, the boss and mounting hole are cylindric, and the diameter of the boss is less than or equal to the peace
The internal diameter in hole is filled, the height of the mounting hole is identical as the height of the boss.
Preferably, threaded hole is offered on the shell, the functional component is fixed by screw and the shell
Connection.
Preferably, the functional component is fixedly connected by buckling with the shell.
Preferably, the functional component is bonded on the housing by glue.
The present invention has the advantages that:Quick assembling unit can in advance be assembled before manufacture with functional component, work as needs
When installing drain valve functional component additional, only entire component need to from top to bottom be exerted a force, the realization group automatically of the Fastener in quick assembling unit
The clamping of part and drain valve is assembled;It is easy to operate, it is not necessarily to screwdriver or glue, meanwhile, the elastic card claw of Fastener is for difference
Producer, various outer diameter drain valve have very strong adaptability.

Specific implementation mode
With reference to the accompanying drawings and detailed description, the present invention will be further described.
As shown in Figure 1, a kind of quick fixation structure of drain valve external connecting function component, including draining valve body 1, functional component 2
And quick assembling unit, 1 upper end of draining valve body have a cylindrical boss 11.
As illustrated in figs. 2-7, quick assembling unit includes shell 3 and four elastic components 4, and shell 3, which is evenly distributed, sets that there are four use
In the mounting groove 31 of installation elastic component 4.Elastic component 4 includes clamping block 41 and elastic card claw 42, and 41 two sides of clamping block are set respectively
There is protrusion 411,31 both sides of mounting groove are equipped with passes through protrusion 411 and card slot with raised 411 matched card slots 311, clamping block 41
311 interference fit is fixedly mounted in mounting groove 31.One end of shell 3 is equipped with threaded hole 32, and functional component 2 passes through screw 5
It is fixedly connected with shell 3.
The other end of shell 3 opens up that there are one the mounting hole 33 that matches with 11 shape of cylindrical boss, cylindrical boss
11 diameter is slightly less than the internal diameter of mounting hole 33.Four clamping blocks 41 are along circumferential uniformly distributed, the elastic card claw 42 of mounting hole 33
One end be the fixing end 421 being connect with clamping block 41, the other end is free end 422, and the free end 422 of elastic card claw 42 is upward
It is obliquely installed, elastic card claw 42 is inwardly projecting relative to the wall surface of mounting hole 32.Shell 3 is matched by mounting hole 33 and boss 11
It closes and is mounted on draining valve body 1 and passes through 42 clamping fixed of elastic card claw.
The operation principle of the present invention is that:When installing quick assembling unit, the elastic card claw 42 of elastic component 4 is in 11 side of cylindrical boss
It can be opened outward under wall effect, for elastic card claw 42 to cylindrical boss 11 without enclasping force, quick assembling unit can the swimmingly row of loading at this time
In the cylindrical boss 11 of water valve 1.After installing, if there is external force that functional component 2 to be made to loosen upwards, elastic component 4 can phase at this time
Drain valve 1 is moved upwards, elastic card claw 42 can be received to the circle of shell 3 under the frictional force of 11 side wall of cylindrical boss
Contracting forms similar back-off effect, the result is that elastic card claw 42 can more be clamped on 11 side wall of cylindrical boss and be not easy to loosen.
Although specifically showing and describing the present invention in conjunction with preferred embodiment, those skilled in the art should be bright
In vain, it is not departing from the spirit and scope of the present invention defined by the appended claims, in the form and details to this hair
It is bright to make a variety of changes, it is protection scope of the present invention.
