Abstract
The utility model discloses a kind of protection structure of quick connector; the quick connector set including the pump housing, on the pump housing and the modular connection coordinated with the quick connector; protection back-up ring is equipped with outside the quick connector; the protection back-up ring has breach; baffle ring is provided with the end of protection back-up ring, the back-up ring portion with modular connection major diameter fit is formed between the baffle ring and protection back-up ring.The utility model can quick-detach modular connection soon while, it is ensured that gap uniformity between modular connection external diameter and bore inner diameter so that when product operationally produces vibrations, modular connection external diameter and bore inner diameter will not be encountered and produce strike note.
Description
Technical field
The utility model is related to water purifier diaphragm pump technical field, more particularly to that is applied on diaphragm pump is quick slotting
The protection structure of joint.
Background technology
The applicant is in Application No. " 201320318013.4 ", and entitled " a kind of water pump with protector quickly connects
Head " utility model patent in disclose set on a kind of protection structure of quick connector, including water pump body, water pump body into
Water swivel and water out adapter, are equipped with protection back-up ring outside water supply connector and water out adapter, and the protection back-up ring is one
Tube-like piece with upper opening.
Said structure, in actual use in the presence of following defect：The circular hole of protection back-up ring formation is easily deformed（Lose
Circle）, which results in gap between modular connection external diameter and bore inner diameter is uneven so that when product operationally produces vibrations,
It can encounter between modular connection external diameter and bore inner diameter and produce strike note.
The content of the invention
For the deficiencies in the prior art, the utility model provides a kind of protection structure of quick connector.
The utility model is achieved by the following technical solution：A kind of protection structure of quick connector, including the pump housing,
The quick connector set on the pump housing and the modular connection coordinated with the connection-peg, are equipped with outside the quick connector
Protect back-up ring, the protection back-up ring has breach, be provided with baffle ring in the end of protection back-up ring, the baffle ring and protection back-up ring it
Between formed and the back-up ring portion of modular connection major diameter fit.
In above-mentioned technical proposal, the protection back-up ring is integrally formed with the pump housing.
In above-mentioned technical proposal, the baffle ring is integrally formed with the protection back-up ring.
The utility model has the advantages that：The utility model can quick-detach modular connection soon while, protect
Gap uniformity between modular connection external diameter and bore inner diameter is demonstrate,proved so that when product operationally produces vibrations, outside modular connection
Footpath and bore inner diameter will not be encountered and produce strike note.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is schematic cross-sectional view of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 2,
A kind of protection structure of quick connector, including the pump housing 1, the quick connector 2 that is set on the pump housing and coordinate with the quick connector 2
Modular connection 3（The mode that quick connector coordinates with the grafting of modular connection 3 belongs to prior art, is not added with embodiment
To repeat）, protection back-up ring 4 is equipped with outside the quick connector 2, the protection back-up ring 4 is integrally formed with the pump housing 1.
The protection back-up ring 4 has breach 41, forms baffle ring 40 in the end of protection back-up ring 4, the baffle ring 40 is with preventing
The back-up ring portion 42 with the major diameter fit of modular connection 3 is formed between bib circle 4.The breach 41 is used to allow instrument to may be inserted into inside
Take out standard component（Modular connection）, it is convenient for changing standard component.
Due to by the spacing modular connection 3 in back-up ring portion 42, can thus greatly reduce the deformation of circular hole herein（Lose
Circle）, so ensure that gap uniformity between modular connection external diameter and bore inner diameter so that product operationally produces vibrations
When, modular connection external diameter and bore inner diameter will not be encountered and produce strike note.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, such as：Protect back-up ring and the pump housing in embodiment, baffle ring and anti-
Be formed in one setting between bib circle, but is not limited for fit system between the two in the application, both above-mentioned
Can also be the mode of other secure fits, the original of the simply present invention described in above-described embodiment and specification each other
Reason, various changes and modifications of the present invention are possible without departing from the spirit and scope of the present invention, above-mentioned changes and improvements
Both fall within the range of claimed invention.
