Fig. 1 is present configuration schematic diagram；
Fig. 2 is explosive view of the present invention；
Fig. 3 is the structural representation that the present invention is connected with endoscope base plate.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
A kind of endoscope chain position-limit mechanism providing referring to Fig. 1, the present invention, main inclusion adjusting screw rod locating dowel 100,
Chain baffle plate 200, some adjusting screw rods 300, fixed mount 400 and screw rod stator 500.
Referring to Fig. 2, adjusting screw rod locating dowel 100, specifically can be set to cylindricality, open up one in the upper end of locating dowel 100
Locating slot 110, opens up two locating slots 110 in the middle part of locating dowel 100, opens up one in the bottom of locating dowel 100 and determines
Position groove 110.
Locating slot 110, specially U-lag, it is used to be connected with the connector 211 of chain baffle plate 200.
Also open up two through holes 120 in the middle part of adjusting screw rod locating dowel 100, through hole 120 is used to and some tune
Section screw rod 300 connects.
Open up a fixing hole in adjusting screw rod locating dowel 100 bottom, it is used to and the first through hole on fixed mount 400
410 match.
Chain baffle plate 200, specifically includes two identical Stainless Steel U catch 210, in each U-shaped catch 210 both sides
Opening arranges two connectors 211.
Connector 211, the U-shaped being specifically arranged to be matched with the locating slot 110 in adjusting screw rod locating dowel 100 is connected
Mouthful, U-shaped catch 210 is injected in the locating slot 110 in adjusting screw rod locating dowel 100 successively by connector 211, thus realization can
The connection of dismounting.
Two U-shaped catch 210 are as follows with the concrete connected mode of adjusting screw rod locating dowel 100：
Referring to Fig. 1, the connector 211 of one of U-shaped catch 210 upper end injects adjusting screw rod locating dowel 100 upper end
In locating slot 110, the connector 211 of lower end injects in the locating slot 110 in the middle of adjusting screw rod locating dowel 100；Another U-shaped keeps off
The connector 211 of piece 210 upper end injects in the locating slot 110 in the middle of adjusting screw rod locating dowel 100, and the connector 211 of lower end is inserted
Enter in the locating slot 110 of adjusting screw rod locating dowel 100 bottom.
In addition, so that U-shaped catch 210 is connected more firmly with adjusting screw rod locating dowel 100, in adjusting screw rod positioning
Post 100 top is additionally provided with a connector 130 and T-shaped with matching supports cap 131, when T-shaped supports cap 131 to put connector into
When in 130, can stationary positioned groove 110 and connector 211.
Support cap 131, specifically one rubber sheet gasket, it is also used for supporting whole position-limit mechanism in endoscope's plastic casing
Rigging position.
Referring to Fig. 2, it is additionally provided with groove 220 in the both sides of the middle part of each U-shaped catch 210.
In each U-shaped catch 210 both sides at groove 220, it is further opened with the connecting hole 230 of a pair of corresponding matching,
It is additionally provided with baffle plate bracing ring 231 between a pair of connecting hole on each U-shaped catch 210.
Baffle plate bracing ring 231 is used to support U-shaped catch 210 both sides, because the catch of U-shaped catch 210 both sides is very thin,
When the connecting hole 230 of U-shaped catch 210 both sides is attached by screw, easily the catch of U-shaped catch 210 both sides is damaged by pressure,
And work as and place baffle plate bracing ring between connecting hole 230 it is possible to provide the strong point for the catch of U-shaped catch 210 both sides, would not
The problem occurring damaging by pressure.
Bracing ring includes the first bracing ring 231 and the second bracing ring 232, and the first bracing ring 231 is placed on the U-shaped gear of upper end
Between two connecting holes 230 in piece 210.
Second bracing ring 232 includes the first contact jaw 232a and the second contact jaw 232b, the internal diameter of the first contact jaw 232a
Less than the internal diameter of the second contact jaw 232b, the second bracing ring 232 is placed on two connecting holes 230 in the U-shaped catch 210 of lower end
Between.
First bracing ring 231 and the second bracing ring 232 are also hollow form, match with connecting hole 230, can be entered by screw
Row series connection.
Referring to Fig. 2, some adjusting screw rods 300, two adjusting screw rods 300 specifically can be set, this 300 points of two adjusting screw rod
Do not put in U-shaped catch 210, and adjusting screw rod 300 can move axially in U-shaped catch 210.
Each adjusting screw rod 300 is provided with limited block 310.
Limited block 310, is one to carry the hook-shaped rectangular bar of rustless steel, opens up both sides in limited block 310 middle part and communicate
