[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of latch mechanism of endoscope setting pipe, holds tightly reliably, and can not damage the image transmission optical fibre in the calibration tube and pass light optical fiber, and easy to assembly, each part detachable is reused, and can not cause the wasting of resources.
The utility model is achieved in that a kind of latch mechanism of endoscope setting pipe, this endoscope comprises that one has main body, a setting pipe and a front end end cover of cavity, described front end end cover is connected the front end of described main body, described setting pipe is through described cavity and front end end cover, wherein: this endoscope comprises that also one is used for the latch mechanism of the described setting pipe of clamping, this latch mechanism places in the described cavity, and is connected in the inner of described front end end cover.
Described latch mechanism comprises a collet chuck, a chuck overcoat and a chuck screw, and described chuck overcoat is connected in the inner of described front end end cover, and this chuck overcoat has the little conical internal cavity of an outer imperial palace; Described collet chuck places within the described conical internal cavity, and the profile of collet chuck is the pyramidal structure that can cooperate with described conical internal cavity, and two ends offer the slit of a plurality of alternative arrangement respectively vertically; Described chuck screw is connected in the outer end of described conical internal cavity and is butted on the outer end of collet chuck, and described collet chuck, chuck overcoat and chuck screw axial centre are equipped with a through hole that supplies described setting pipe to run through.
The conical internal cavity of described chuck overcoat and the tapering of described collet chuck are 5～30 degree.
The conical internal cavity of described chuck overcoat and the tapering of described collet chuck are 25 degree.
The inner of described front end end cover is offered a groove vertically, and described chuck overcoat is embedded in this groove, and resists fixing by the screw of the described groove of a radial penetration.
The utlity model has following advantage: endoscope of the present utility model does not adopt glue to fix calibration tube, but set up a latch mechanism, this latch mechanism utilizes the collet chuck of pyramidal structure to cooperate with the conical internal cavity of chuck overcoat, and the outer end of collet chuck has the slit of a plurality of alternative arrangement, under the promotion of chuck screw, can radially evenly shrink, hold the setting pipe tightly, hold tightly reliably, and can not damage the image transmission optical fibre in the calibration tube and pass light optical fiber, the tapering of collet chuck is limited in 5～30 degree scopes, can not produce self-locking, easy to assembly, each part detachable is reused, and can not cause the wasting of resources.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the utility model endoscope assembly structure cross-sectional schematic.
Fig. 2 is the utility model endoscope structure decomposing schematic representation (omitting main body and setting pipe among the figure).
Fig. 3 is the structural representation of the collet chuck of the utility model latch mechanism.
[embodiment]
See also illustrated in figures 1 and 2, the utility model endoscope comprises a main body 1, one setting pipe 2, one front end end cover 3 and a latch mechanism 4, main body 1 has a cavity 12, described front end end cover 3 is connected the front end of described main body 1, described setting pipe 2 is through described cavity 12 and front end end cover 3, described latch mechanism 4 is used for the described setting pipe 2 of clamping, latch mechanism 4 comprises a collet chuck 41, an one chuck overcoat 42 and a chuck screw 43, this latch mechanism 4 places in the described cavity 12, and be connected in the inner of described front end end cover 3 and described collet chuck 41, chuck overcoat 42 and chuck screw 43 axial centre are equipped with a through hole 410 (420) (430) that supplies described setting pipe 2 to run through.
The chuck overcoat 42 of described latch mechanism 4 is connected in the inner of described front end end cover 3, the inner of described front end end cover 3 is offered a groove 32 vertically, described chuck overcoat 42 is embedded in this groove 32, and resists fixing by the screw 34 of the described groove 32 of a radial penetration; And this chuck overcoat 42 has the little conical internal cavity 422 of an outer imperial palace.
Please extremely shown in Figure 3 in conjunction with Fig. 1, described collet chuck 41 places within the described conical internal cavity 422, and the profile of collet chuck 41 is the pyramidal structure that can cooperate with described conical internal cavity 422, and two ends offer the slit 412 of a plurality of alternative arrangement respectively vertically.
43 on described chuck screw is connected in the outer end of described conical internal cavity 422 and is butted on the outer end of collet chuck 41.
The conical internal cavity 422 of described chuck overcoat 42 and the tapering of described collet chuck 41 are 5～30 degree, and the two tapering is limited in 5～30 degree scopes, can not produce self-locking, are 25 the bests when spending at tapering.
