Detailed description of the invention
Hereinafter, will be described in detail with reference to the accompanying drawings the triggering plug in duct being prone to parts assembling of the present invention even
The structure of connection device.
In invention description below, unnecessary be judged as relevant known function or structure
In the case of ground specific description can obscure idea of the invention, by description is omitted.And, after
The term stated is the function considered in the present invention and the term defined, may be according to user, utilization
Person or convention etc. and different.Therefore, its definition should entire content based on this specification be carried out.
Fig. 4 is to illustrate that the present invention's is prone to the structure triggering inserted catheter connection device that parts assemble
Axonometric chart, Fig. 5 is the exploded perspective view of Fig. 4, and Fig. 6 is the sectional view of Fig. 4.
With reference to Fig. 4 and Fig. 6, the present invention is prone to the triggering inserted catheter connection device A that parts assemble
Including connecting tube 10, O 20, supporting member 30 and jaw member 40.
First, hollow form is made and be formed as to connecting tube 10 by metal material, and two ends with central part are
Center carries out expander and is formed with conduit accepting groove 11, in order to insert conduit P at two ends, at each conduit
Accepting groove 11 end carries out expander and is formed with fixing groove 13, the end at fixing groove 13 be formed more to
The first inclined plane 15 that outside is the most downward-sloping, the end in the first inclined plane 15 is formed with conduit and introduces
Mouth 17, in order to prevent conduit P sagging.Here, connecting tube 10 is soldered or logical after carrying out expander
Cross medicine and carry out surface process.Furthermore it is preferred that the conduit intake 17 of connecting tube 10 is in the first inclined plane
The most horizontal-extending formation of end of 15, in order to prevent that conduit P's is sagging, and formed ratio is led
The diameter of pipe P is big, is attached to conduit P or inserts other circular slab form after inserting conduit P
Handling instrument (not shown) maintains and the interval of conduit P, so as to promote to be illustrated
Jaw member 40 carries out the handling of conduit P.
Additionally, O 20 is formed and the company of being inserted into by elastomeric material (such as rubber or synthetic resin)
The fixing groove 13 of adapter 10, to maintain watertightness and to provide elastic.Here, O 20 deforms with logical
The conduit intake 17 crossing connecting tube 10 is inserted into the fixing groove 13 of connecting tube 10.
Additionally, supporting member 30 is formed as the ring of tabular by elastomeric material (such as rubber or synthetic resin)
Shape, is inserted in O 20 rear end.Here, supporting member 30 deforms with leading by connecting tube 10
Pipe intake 17 is inserted into the fixing groove 13 of connecting tube 10.
Additionally, jaw member 40 is passed through by such as rubber or synthetic resin material by multiple jaws (jaw) 41
The elastic component 43 that material is formed is interconnected to form as circle, is inserted into the first inclination of connecting tube 10
Face 15 is internal, and wherein, described jaw 41 is formed with sawtooth 41a, outside at the inner peripheral surface of common morphological
Side face is formed with second inclined plane 41b with the first inclined plane 15 same tilt degree with connecting tube 10.
Jaw member 40 is be combined with each other with elastic component 43 by insertion or bonding way.Here, preferred jaw
The diameter that the diameter of component 40 is formed than conduit P little and introduce conduit P time jaw member 40 long
Degree expansion.
The triggering plug in duct being prone to parts assembling of the present invention is described in detail even hereinafter with reference to accompanying drawing
The operation principle of connection device.
Fig. 7 is for illustrating that the present invention's is prone to the portion triggering inserted catheter connection device that parts assemble
The sectional view of part assembling process, Fig. 8 to Figure 10 is for illustrating that the present invention's is prone to touching of parts assembling
Send out the sectional view of the assembling process of inserted catheter connection device.
First, conduit accepting groove 11, fixing groove 13, first are formed connecting tube 10 is carried out expander
With medicine, surface is processed after inclined plane 15 and conduit intake 17.Now, as required
Connecting tube 10 can be welded with other junctional complex (not shown), in the case of welding,
With medicine, surface is processed after welding.
Then, jaw member 40 is made by other operation.
When completing the making of connecting tube 10 and jaw member 40, as it is shown in fig. 7, make O type
Circle 20 deforms and is inserted into the conduit intake 17 of connecting tube 10, so that O 20 is positioned at connection
The fixing groove 13 of pipe 10.
Then, make supporting member 30 deform and be inserted into the conduit intake 17 of connecting tube 10, so that
Supporting member 30 is positioned at the rear end of O 20 in the fixing groove 13 of connecting tube 10.
Finally, jaw member 40 is made to deform and be inserted into the conduit intake 17 of connecting tube 10, so that
Jaw member 40 is positioned at the first inclined plane 15 of connecting tube 10.
When completing the insertion of O 20, supporting member 30 and jaw member 40, such as Fig. 8 institute
Showing, the conduit intake 17 in connecting tube 10 inserts conduit P.
So, conduit P promotes jaw member 40 to enter, when jaw member 40 is being promoted
During when can not move further due to supporting member 30 and O 20, as it is shown in figure 9, logical
Cross elastic component 43 expansion diameter and transtracheal catheter P.
And, the most through supporting member of conduit P 30 and O 20 and be stuck in leading of connecting tube 10
Pipe accepting groove 11 end is fixed.
When in such a state due to hydraulic pressure and external impact (earthquake etc.) or differential settlement etc. and
When conduit P produces tensile force, as shown in Figure 10, conduit P moves the most laterally with jaw member 40.
So, jaw member 40 and conduit P first move along the first inclined plane 15 of connecting tube 10,
Can become narrow gradually owing to tilting the internal diameter of jaw member 40, thus the sawtooth 41a of jaw 41 is pressed into conduit
P and block further mobile, thus, overcome tensile force.
On the other hand, when when inserting conduit P, the handling instrument of circular plate-like shape being pressed into even
During the conduit intake 17 of adapter 10, jaw member 40 can be pushed to inner side, leads accordingly, it is capable to extract
Pipe P.
The present invention can carry out various deformation, can take variform, in above-mentioned detailed description of the invention
Only its special embodiment is described.But, the present invention is interpreted as being not limited to detailed
The special form mentioned in explanation, on the contrary, also should include defining by appended claims this
All deformations in bright spirit and scope and equipollent and substitute.
