Specific embodiment
As shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 and Figure 10, a kind of plastics clip, including hoop body 1 and urgent screw
2, described hoop body includes holding section 11 tightly, is shaped in the described urgent proximal segment 12 holding section two ends tightly and tension section 13, described holding
The curved thin ribbon shaped of section, and described holding section includes the first segmental arc 111, is shaped in second arc at described first segmental arc two ends
Section 112, the radius of curvature of described first segmental arc is more than the radius of curvature of described second segmental arc, and described urgent screw penetrates and is positioned
The middle part of described urgent proximal segment, and described urgent screw can be threadeded with described tension section, make described the first arc holding section tightly
Section and two the second segmental arcs are bent to form annular.In said structure, take full advantage of plastic material and there is flexible flexibility
Characteristic, after the holding section to hoop body carries out rational radian radius of curvature design, forms annular, circle after it can be made to bend
Annular can preferably mate being fastenedly connected of flexible pipe and hard tube.In said structure, hold the curved thin ribbon shaped of section tightly, take into full account
Arrive the convenience of Making mold, can effectively reduce die sinking and manufacturing cost;In said structure, urgent screw penetrates and is positioned
The middle part of the urgent proximal segment of hoop body, make hoop body be integrally formed with urgent screw, it is to avoid easily loses part in user's disassembly process
Situation, and can achieve the Quick fastening of flexible pipe and hard tube, easy and simple to handle efficiently.
Preferably, the radius of curvature of described first segmental arc is 2-5 times of the radius of curvature of described second segmental arc.As one kind
The radius of curvature of the second segmental arc can be designed less (more bigger than flexible pipe radius to be tightened) by preferred implementation, will
The curvature design of the first segmental arc is larger, typically takes 2-5 times of the second segmental arc radius of curvature.Such radian radius of curvature design
Afterwards, form annular after it being made to bend.
Preferably, the described medial surface holding section tightly is provided with least one convex tendon 1101.Preferably, it is provided with two convex tendons, this two
Bar convex tendon is spaced located at the medium position holding section medial surface tightly along the length direction holding section tightly, using plastics clamp connection flexible pipe
During with hard tube, play the effect giving full play to fastening force.
Preferably, the described lateral surface holding section tightly is provided with least one reinforcement 1102.Preferably, it is provided with two reinforcements,
This two reinforcements are spaced located at the marginal position holding section lateral surface tightly along the length direction holding section tightly, in order to improve embracing of hoop body
The structural strength of tight section.
Preferably, the middle part of described urgent proximal segment is provided with via 121, and the side of described urgent proximal segment is provided with the first slot to make way 122;
The middle part of described tension section is provided with internal thread hole 131, and the side of described tension section is provided with the second slot to make way 132;Described urgent spiral shell
Silk includes urgent flange 22, anticreep cervical region 23, anticreep flange 24 and the external thread column 25 setting gradually;Described anticreep cervical region penetrates
Described in the hole excessively, and described urgent proximal segment stop is between described urgent flange and described anticreep flange;Described external thread column and institute
Stating internal thread hole can be threaded, and when threaded, and described anticreep flange is placed in described first slot to make way and described
In the cavity that second slot to make way is formed, at a distance of setpoint distance between described urgent proximal segment and described tension section, form urgent gap 14.
So, by the cooperation of the via in the middle part of the urgent proximal segment of the anticreep cervical region of urgent screw and hoop body, and the urgent proximal segment of hoop body with
The urgent flange of urgent screw and the cooperation of anticreep flange, are capable of urgent screw and penetrate the work(being positioned the middle part compeling proximal segment
Can, so that hoop body is integral with urgent screw-shaped, reach the purpose avoiding easily losing part in user's disassembly process.Pass through
The external thread column of urgent screw and the cooperation of the internal thread hole at middle part of the tension section of hoop body, are capable of urgent screw and tension
The threaded function of section.The cavity being formed by the first slot to make way and the second slot to make way and the cooperation of anticreep flange, Neng Goushi
The first segmental arc of section and effectively closing up of the second segmental arc is held tightly when now fastening.By compel between proximal segment and tension section at a distance of set away from
From the urgent gap of formation, using the teaching of the invention it is possible to provide lasting pretightning force is it is ensured that fasten the continued reliability of connection.
Preferably, described internal thread hole is parallel with the opening direction of described via.By by the via of urgent proximal segment and tension
Section internal thread hole opening direction be designed to parallel, can be easy to die sinking and molding, thus effectively reduce manufacturing cost.
Preferably, described urgent screw also includes handle head 21, and described handle head is dorsad described located at described urgent flange
The side of anticreep cervical region, and described handle head has been provided with the anti-skidding muscle 211 of anti-skidding effect.Can be easy to by designing handle head
Tightening operation, can play anti-skidding effect by arranging anti-skidding muscle.
Preferably, the diameter with diameter greater than described via of described anticreep flange, and described anticreep flange is provided with taper
Fillet 241 faces 242 directly with several.In said structure, the diameter with diameter greater than via of anticreep flange, can make its backstop in
The side of urgent proximal segment, coordinates urgent flange, urgent screw can be made to penetrate and be positioned in the hole, be unlikely to drop, so as not to urgent
Screw drops and brings the worry of part loss to user.In said structure, taper fillet 241 and some is provided with anticreep flange
The individual effect faced 242 directly, can play the via 121 facilitating anticreep flange 24 to pass through urgent proximal segment 12, facilitates urgent screw and hoop
Being located by connecting of the urgent proximal segment of body.It is furthermore preferred that taking the diameter 0.1~0.5mm bigger than the diameter of via 121 of anticreep flange 24,
And face 242 quantity directly and be set to 2-5.
Preferably, the composite wood of composite by PP or PP and GF of described hoop body and urgent screw or PA or PA and GF
Material or ABS or PVC make.Using the composite of PP, PP and GF, the composite of PA, PA and GF, the plastic cement material such as ABS, PVC
Material, plastic mould easy to use is produced in batches, and manufacturing cost is extremely low.
Referring to Fig. 1, Fig. 2 and Fig. 3, the fastening structure of a kind of flexible pipe and hard tube, including described plastics clip, also wrap
Include flexible pipe 3, hard tube 4 and sealing ring 5, the circumferencial direction of described hard tube is provided with cannelure 41, described Hose Jacket is located at described hard
Pipe is outer, and described sealing ring is in described cannelure, and is located between described flexible pipe and described hard tube, the embracing of described plastics clip
Tight section is held tightly outside the described flexible pipe at described sealing ring.So, by being pressed into the urgent screw of plastics clip in hoop body
Urgent proximal segment 12 in, so that urgent screw 2 is threadeded with tension section 13, you can to realize the function of approaching locking, flexible pipe 3 is fastened
Be connected to hard tube 4 cylindrical on, the sealing ring 5 sealing is set between flexible pipe 3 and hard tube 4.
