Description
Technical field
This utility model relates to household water filter technical field, more specifically, relates to the pipeline fast plug-in card pawl of connection that a kind of water processes.
Background technology
At present, known fast plug-in card pawl international, domestic is made up of card and plastics cutting ferrule.When pipeline inserts quick connector, the plastic clip on claw is enclosed within the effect of joint shell and makes card clamp pipeline outer surface, forms stopping function, prevents pipeline from having taken off and leak.But, a lot of situations are that the retaining effect of claw is undesirable, and because card and pipeline outer surface are all the arc surfaces of same diameter, the upper positive force of camber line contact is little, retaining weak effect.
On the other hand, the oblique contract of existing claw is easily skidded, and its reason is: the design of card back-off stopping function is the best, and coordinating in plastics cutting ferrule contract oblique with the shell of fast socket, connector has on contact surface what card separated with steel disc to thrust burr, affects the chucking power of claw.
Utility model content
Technical problem to be solved in the utility model: for the deficiency of prior art, thering is provided a kind of claw, this claw can not only clamp pipeline well, and can be clamped by pipeline solid and reliable, prevent from getting loose and leaking, to overcome the existing fast plug-in card unstable shortcoming of pawl clamping.
The technical solution of the utility model is: claw, and including card, cutting ferrule, cutting ferrule is that claw is inserted in quick connector in the steel disc upper molding with card, and described card punching separation face from steel band is not located on the contact surface of cutting ferrule and quick connector.
Described card includes bare terminal end, embedded end, is provided with pointed tooth in bare terminal end both sides.
Bare terminal end and the pipeline reverse angle in direction that gets loose is that β, β are less than 30 °.
Described cutting ferrule includes that skirt section, claw, described card are embedded in claw, and the end outer wall of described claw is hook-shaped, and described claw is provided with some grooves thus forms multiple rest shoe.
The inwall of described quick connector is provided with wedge surface, and the hooked end outer wall of described rest shoe is pressed on the wedge surface of quick connector.
This utility model has the advantages that
Claw structure of the present utility model is reliable, it is possible to reduce intubate the drainage that road connects soon, uses can reduce on household water filter and causes people's family's property to lose because leaking.

Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, and the most same or similar label represents same or similar element or has the element of same or like function.The embodiment described below with reference to accompanying drawing is exemplary, is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.
See Fig. 1-5, this utility model provides a kind of claw, including card 2, cutting ferrule 1, is fastened in the steel disc 7 upper molding with card, and claw is inserted in quick connector 8, described card includes bare terminal end, embedded end, be provided with pointed tooth in bare terminal end both sides, bare terminal end and the pipeline direction that gets loose inversely forms card bending retaining angle beta, and β is less than 30 °；Card punching separation from steel band is not on the cutting ferrule contact surface with quick connector.As it is shown in figure 1, one end of claw is stretched in quick connector 8, PE pipe 5 extend in quick connector 8 through the endoporus of claw, arranges sealing ring 6 between quick connector 8 and PE pipe 5.
Described cutting ferrule 1 includes that skirt section 11, claw 12, described card 2 are embedded in claw 12, and the end outer wall of described claw is hook-shaped, and described claw is provided with some grooves 14 thus forms multiple rest shoe.The outer wall in skirt section 11 arranges the gripping edge 13 being prone to finger cramping cutting ferrule.In cutting ferrule claw, card arranges the folded edge 22 getting loose in opposite direction with pipeline.
The inwall of described quick connector is provided with wedge surface, makes the inner chamber of quick connector form inner shell profile face 3 and inner shell cammed surface 4, and the hooked end outer wall of described rest shoe is pressed on the wedge surface of quick connector.The oblique contract angle of wedge surface is a, and the card bare terminal end of claw forms back-off sheet, and the oblique contract formed with the shell of fast socket, connector by plastics cutting ferrule on claw is coordinated, and makes claw clamp upper and lower PE pipe firmly.
The specific works principle of fast socket, connector is: is formed in lower PE pipe is inserted into adapter by claw and with sealing ring and is tightly connected, upper PE pipe connects again by fast socket, connector upper clipping claw (not cutting open in figure) and is tightly connected with the formation of upper sealing ring, has been achieved in that the connection of plugging in water route.In order to prevent the pipe of PE up and down caused due to hydraulic pressure from taking off from fast socket, connector, being provided with back-off card on claw, can be coordinated by the oblique contract that plastics cutting ferrule on claw is formed with the shell of fast socket, connector, oblique contract angle is a, makes claw clamp upper and lower PE pipe firmly.
This utility model forms pointed tooth on card, and get loose the reverse crimping that angle is β in direction at axial design and the pipeline of claw, the pipeline making water purifier be connected under the effect of claw to clamp more solid and reliable, prevent from getting loose and leaking, thus reach to improve purpose.
The cast of above-mentioned claw is die-cut goes waste material method, comprises the following steps: S1) profile P and outer mold surface Q in punching card on steel disc, connect with rib between adjacent outer mold surface Q, form the blank of card；S2) the blank casting plastic at card forms cutting ferrule, and the blank of card is positioned at the claw of cutting ferrule, and cutting ferrule outside diameter is less than by the maximum gauge of outer mold surface Q place cylindrical, and the claw at corresponding rib is provided with groove 14；S3) in the claw groove of cutting ferrule, the rib 21 of card is excised.
This utility model cuts off steel disc waste material in order to avoid the outer wall at cutting ferrule, card is not located on the cylindrical of outer mold surface Q with the connection strap of steel disc, and be provided in groove 14 region of claw, when going waste material to cut, by card punching separation from steel band in the groove 14 of plastics cutting ferrule, plastics cutting ferrule is made to contact with the shell inclined-plane Smooth of plug device quickly.
Only specific embodiment of the utility model disclosed above; it is not intended that the restriction to this utility model protection domain; for this utility model person of an ordinary skill in the technical field; without departing under general idea premise of the present utility model; the variations and alternatives needing not move through creative work made according to technical solutions of the utility model, all should fall within protection domain of the present utility model.
