Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Fig. 3 Fig. 4, a kind of foley's tube locked, including outer tube, core pipe, handle 1 and seal wire 2, core pipe position
In in outer tube, seal wire 2 is located in core pipe, and outer tube back-end is connect with handle 1, and core pipe rear end is located in handle 1,2 rear end of seal wire from
Handle 1 is pierced by, and 1 rear end of handle forms linkage section 11, is formed seal chamber in linkage section 11, is provided with sealing ring 4 in seal chamber, leads
Silk 2 is passed through from seal chamber.
The connector 3 that can be moved axially and lock along linkage section 11 is connected on 1 linkage section 11 of handle, connector 3 has insertion
Inner cylinder 31 in seal chamber pushes against 4 rear end of sealing ring when inner cylinder 31 moves forward, by the sealing ring 4 for pushing against power and deforming
It clamps seal wire 2 and limits seal wire 2 and moved in handle 1.
The mechanism for moving axially and locking between 1 linkage section 11 of connector 3 and handle are as follows: connector 3 is including inner cylinder 31 and outside
Cylinder 32, inner cylinder 31 and 32 rear end of outer barrel are connected as one, and inner cylinder 31 is located in outer barrel 32, outside inner cylinder 31
The ring cavity being inserted into for linkage section 11 is formed between 32 inner wall of wall and outer barrel；32 inner wall of outer barrel forms internal thread segment, connection
11 rear ends of section form external thread section, and the intracavitary outer barrel 32 with connector 3 of 11 rear end insertion ring of linkage section is spirally connected.Pass through swivel
3, realize axial movement of the inner cylinder 31 in seal chamber, and then realize the abutting state to 4 rear end of sealing ring.
It is provided with inner baffle ring 321 on 32 inner wall of outer barrel of ring cavity front end, a pair of of bayonet is opened up on inner baffle ring 321, is connected
Section 11 forms a pair of of card convex, and two card convexs can be passed into ring cavity from two bayonets.After linkage section 11 is stuck in ring cavity,
When connector 3 11 rear end of linkage section be in unscrew state when, make connector 3 be not easy to fall down,
Anti-skid washer 5 is provided on rear side of sealing ring 4, inner cylinder 31 is pushed against through anti-skid washer 5 and 4 rear end of sealing ring.It is anti-skidding
Sealing ring 4 is damaged when the effect of washer 5 is to prevent 31 front end of inner cylinder from pushing against sealing ring 4.
When operation, the inner baffle ring 321 on connector 3 is smoothly and after the cooperation of 1 card convex of handle, and by rotary joint 3, control is connect
First 3 move forward and backward on linkage section 11, and by rotating clockwise connector 3, connector 3 can squeeze anti-skid washer 5, non-slip mat down
