Abstract
A kind of lock fastener used for socket pipe material, pertaining to water supply and drainage pipe material technical field, is used to solve the problem of easy loosening of pipe joint. The technical plan is as the following: the fastener consists of two chucks, a stay bolt and a lock bolt. The chuck is of ring shape, formed by butt joint of two half rings, with lock bolt hole arranged on the butt joint surface; IR. of the chuck matches with O.D. of the pipe, and the two chucks are connected by stay bolt. The utility model fixes pipe joint reliably by the function of both lock bolt and stay bolt to prevent pipe joint from loosening effectively. The utility model is of simple structure, compact shape, small self-weight, and easy installation and operation, and can be widely used at various pipe joints, especially suitable for use at pipe joints of the overhead installed pipe and pipe joints with bigger medium impact.
Description
Technical field
The utility model relates to a kind of water-feeding pipes special purpose parts, particularly prevents the fastening piece that PVC-U, PE plastic tube interface get loose, and belongs to plumbing tubing technical field.
Background technique
In recent years, PVC-U tubing development rapidly, premium properties such as its light weight, anticorrosive, specious, easy installation, the material of main part as pipeline generally uses in various water-feeding ﹠ drainaging pipelines gradually.After PVC-U plastic tube (tubing that also comprises other material) was shaped, tubing one end formed female end after enlarging processing, be provided with O-ring seal in the female end, and the bulk end of tubing is inserted female end and realized the connection and the sealing of pipeline by O-ring seal.Usually, for being embedded in underground pipeline, because its all round filling and inhibition of earth, jointing can not get loose.But in particular cases as aerial pipeline, because pipeline all round lacks the drag effect of earth, when the medium that transmits in the pipeline produced fluctuation, pipeline was impacted and oscillating action, and pipe joint is got loose, and causes the pipe leakage phenomenon at some.At this problem, it is very necessary that the pipeline of installing for special occasions is provided with securing means at jointing.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of anti-loose fastening piece that is used for the pvc pipe material that can effectively avoid the tubing interface to get loose is provided.
The alleged problem of the utility model solves with following technical proposals:
A kind of anti-loose fastening piece that is used for socket joint tubing, its specialization is: described fastening piece is made up of two chucks 1, stay-bolt 3 and lock bolt 2, described chuck is a ring-type, it is formed by two semi-ring butt joints, its interface is provided with the locking screw keyhole, chuck internal diameter and tube outer diameter are complementary, and are connected by stay-bolt between two chucks.
The above-mentioned anti-loose fastening piece that is used for socket joint tubing is provided with packing ring 6 with the chuck inner radius on the two semi-ring interfaces of described chuck.
The above-mentioned anti-loose fastening piece that is used for socket joint tubing, described chuck end face is established plum blossom shape flange, and flange which is provided with the stay-bolt hole along the chuck circumference uniform distribution.
The utility model is the anti-loose fastening piece of a kind of PVC of being exclusively used in, PE pipe joint, and it is bigger than tubing main body section diameter according to the jointing female end of PVC, PE tubing, should not adopt full characteristics of applying formula to design.Its overall structure is made of two chucks that stay-bolt connects, and two chucks are separately fixed at the both sides of tubing interface, by the effect of lock bolt and stay-bolt, with tubing interface secure fixation, prevent that effectively the tubing interface from getting loose.The utility model is simple in structure, compact appearance, little from body weight, fitting operation is very convenient, can be widely used in various PVC, PE pipe joint place, is specially adapted to built on stilts pipe laying, medium impacts bigger pipe joint place.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the plan view of Fig. 1.
Each parts label is expressed as follows among the figure: 1. chuck; 2. lock bolt; 3. stay-bolt; 4. tubing female end; 5. tubing main body; 6. packing ring.
Embodiment
The utility model is made up of ring-type chuck, stay-bolt 3 and lock bolt 2, chuck is two, and each chuck is formed by two semi-ring butt joints, and two semi-ring interfaces are provided with the locking screw keyhole, chuck internal diameter and tube outer diameter are complementary, and are connected by stay-bolt between two chucks.During use, two chucks are fixed on the female end 4 and PVC-U tubing main body 5 of PVC-U tubing jointing by lock bolt respectively, position between two chucks is fixed by stay-bolt, and the interface of tubing can not get loose phenomenon under external force promptly by secure fixation yet like this.
For reducing from body weight, the chuck end face is designed to the plum blossom shape, and the plum blossom leaf which is provided with the stay-bolt hole along the chuck circumference uniform distribution.Present embodiment is provided with four stay-bolts, can be according to the number of pipe diameter specification and use condition increase and decrease stay-bolt.The diameter of stay-bolt and lock bolt can be selected according to the nominal pressure of tubing.Consider in use, prevent chuck damage tubing, on chuck two semi-ring interfaces, be provided with packing ring 6 with the chuck inner radius.
