Abstract
The invention discloses a kind of connection self-locking structure connected for pipeline, including body, the port diameter of body is less than the diameter of tube cavity, and be gradually increased by the tube wall diameter body port to tube cavity, until tube wall diameter is equal with intracavity diameter, insert fixture from body port, the outer snapping of body port is with the capping of through hole.The invention has the beneficial effects as follows, easy to connect, safe and reliable.
Description
Technical field
The present invention relates to pipeline connection technology, a kind of connection self-locking structure connected for pipeline.
Background technology
Pipeline connection at present uses the connected modes such as hot melt, screw thread, gluing, card pressure bother very much and be inconvenient to tie up mostly
Repairing, the pipeline of unlike material can not be connected directly to each other, and this technology uses socket joint connected mode, it is not necessary to hot melt, screw thread, glue
The direct socket joints of mode such as viscous, card pressure connect the most permissible, and the pipeline of unlike material can be directly connected to without conversion or use other
Method solves.
Summary of the invention
The invention aims to solve the problems referred to above, devise a kind of connection self-locking structure connected for pipeline.
Realizing above-mentioned purpose the technical scheme is that, a kind of connection self-locking structure connected for pipeline, including pipe
Body, the port diameter of body is less than the diameter of tube cavity, and by the tube wall diameter body port to tube cavity is
It is gradually increased, until tube wall diameter is equal with intracavity diameter, inserts fixture from body port, the outer snapping band of body port
There is the capping of through hole.
The structure of described fixture is to be provided with boss at the upper end port edge of metal cylinder, at the lower end port of metal cylinder
Edge is provided with multiple outwardly metal claw.
Through hole in described capping aligns with body port, and through hole is provided around solving lockhole.
Described metal claw is to be connected with metal cylinder by one end and relative to metal cylinder bandy strip shell fragment and solid
It is scheduled on what the calvus that the shell fragment other end inwardly buckles collectively constituted.
Described metal claw sheet is while processing the rectangular metal sheet of multiple sawtooth.
Angle between described shell fragment and metal claw sheet is not less than 90 degree.
Described metal claw is more than body port with body port to tube cavity relative to metal cylinder outwardly angle
Between tube wall angulation.
Described boss is the geometric form laminated structure corresponding with unlocking hole site.
Utilize the connection self-locking structure connected for pipeline that technical scheme makes, there is installation and maintenance side
Just, safe and efficient, can directly the pipeline of all kinds of materials be attached without using conversion head, installation and maintenance refer to without technology
Lead and train, saved the time of workman's installation and maintenance, save installation and maintenance expense.

Fig. 1 is the structural representation connecting self-locking structure connected for pipeline of the present invention；
In figure, 1, body；2, fixture；3, capping；4, metal cylinder；5, metal claw；6, lockhole is solved；7, shell fragment；8, calvus；
9, through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is specifically described, if Fig. 1 is the connection connected for pipeline of the present invention
The structural representation of self-locking structure, as it can be seen, a kind of connection self-locking structure connected for pipeline, including body 1, body
Port diameter is less than the diameter of tube cavity, and is to be gradually increased by the tube wall diameter body port to tube cavity
, until tube wall diameter is equal with intracavity diameter, inserting fixture 2 from body port, the outer snapping of body port is with through hole 9
Capping 3.Wherein, the structure of described fixture is to be provided with boss at the upper end port edge of metal cylinder 4, under metal cylinder
It is provided with multiple outwardly metal claw 5 at end port edge；Through hole in described capping aligns with body port, and through hole week
Enclose and be provided with solution lockhole 6；Described metal claw is to be connected and relative to metal cylinder bandy strip bullet with metal cylinder by one end
Sheet 7 and be fixed on what the calvus 8 that the shell fragment other end inwardly buckles collectively constituted；Described metal claw sheet is for while processing multiple sawtooth
Rectangular metal sheet；Angle between described shell fragment and metal claw sheet is not less than 90 degree；Described metal claw relative to metal cylinder to
The angle opened outward is more than the tube wall angulation between body port and body port to tube cavity；Described boss be with
Unlock the geometric form laminated structure that hole site is corresponding.
In use, pipeline directly inserts body by the through hole in capping to this device, solid under the effect inserting pipeline
Locking member slide downward is until the boss on metallic sheath is blocked by body port.Fixture is during downwards, due to metal
Pawl relative to metal cylinder outwardly angle more than formed by the tube wall between body port and body port to tube cavity
Angle, so metal claw can be close to connection pipe body inwall and move down.Because of by the pipe body port to tube cavity
Wall diameter is gradually increased, so the inner chamber of body port becomes inner small and outside big truncated cone-shaped, so the mistake inserted at pipeline
The open-shaped state of metal claw in journey, will not hinder pipeline to insert.If the pipeline inserting body moves out, at the work of frictional force
Pipeline will be followed to move out with lower fixture to block, due in body port until the boss on metallic sheath is capped
Chamber becomes inner small and outside big truncated cone-shaped, so now metal claw buckles pipeline along inner-walls of duct to contract, and then stops pipeline
It is drawn out.
When pipeline is split by needs with body, pipeline can be pulled out, until the locking of pipeline fixture can not be again
During pull-out, a thin metallic rod can be inserted solution lockhole and fixture is pushed down on so that metal claw opens, and then pulls out pipe
Road realizes pipeline and the separate operation of body.
The pipeline that can be realized unlike material by this device is connected, and then reduces construction requirement, improves construction effect
Rate.
Technique scheme only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
Some variations may made some of which part all embody the principle of the present invention, belong to protection scope of the present invention it
In.
