Detailed Description
The invention will now be further described by way of specific examples with reference to the accompanying drawings, which are given by way of illustration only and not by way of limitation.
Examples
A light source light path dimming device of an endoscope, see fig. 1 and 2, includes a light source device 2, which supplies illumination light as an external device of the endoscope 1. Wherein the endoscope 1 is provided with an elongated insertion portion (not shown in the figures) for insertion into a body cavity, the other end of the endoscope 1 is provided with a light source connector 11, and after the light source device 2 is inserted into the light source connector 11, a light guide at the end thereof receives light from the light source device 2, and finally the effect of illumination of the end of the elongated insertion portion at the other end of the endoscope 1 is achieved.
The light source device 2 is internally provided with a light source 21 for emitting illumination light, the light source 21 may be a hernia lamp or an LED, the light source 21 emits parallel light, the parallel light is emitted from the light source 21, then the parallel light is emitted to a convex lens 22 through a light adjusting device, and finally, an optical path is converged to the end of the light source connector 11 through the convex lens 22.
Referring to fig. 3-13, the dimming device specifically includes a dimming cylinder, the dimming cylinder has a light-passing hole 411 capable of passing through a light path, a plurality of fan-shaped laminated light-shielding sheets are disposed in the light-passing hole 411, wherein the light-shielding sheets are divided into a fixed light-shielding sheet 51, a follow-up light-shielding sheet 52 and a driving light-shielding sheet 53, and the center of each light-shielding sheet is pivoted by a pivot shaft. The forward linkage structure and the reverse linkage structure are arranged between the follow-up light shielding sheets 52, between the follow-up light shielding sheets 52 and the fixed light shielding sheets 51 and between the follow-up light shielding sheets 52 and the driving light shielding sheets 53, so that when the driving light shielding sheets 53 rotate, the follow-up light shielding sheets 52 can be driven to be unfolded or folded one by one to be stacked, and the effect of changing the light quantity of the light through holes 411 is achieved.
The specific forward linkage structure is as follows: the toggle protrusions 61 are provided on the same radius side of each of the follow-up light shielding sheets 52, and the toggle protrusions 61 are also provided on the radius side of the driving light shielding sheet 53 on that side. The hooking protrusion 62 is provided on the radius edge of the other side of the follower light shielding sheet 52 opposite to the poking protrusion 61, and the hooking protrusion 62 is also provided on the same side of the fixed light shielding sheet 51, and the protruding directions of the poking protrusion 61 and the hooking protrusion 62 are opposite. Meanwhile, friction force formed by extrusion is formed between each stirring convex strip 61 and the surface of the follow-up shading sheet 52, and the magnitude of the friction force sequentially increases along the direction of driving the shading sheet 53 to the fixed shading sheet 51. Thus, when the driving light shielding sheet 53 rotates, since the friction force between the poking convex strip 61 and the follow-up light shielding sheet 52 arranged on the driving light shielding sheet 53 is smaller than the friction force between the poking convex strip 61 and the follow-up light shielding sheet 52 on the follow-up light shielding sheet 52 of the next stage, only the driving light shielding sheet 53 rotates to adjust light before the poking convex strip 61 does not contact the hooking convex strip 62; and when the following shading sheet 52 of the next stage is driven, only the following shading sheet 52 of the cover sheet rotates to adjust the light, and the following shading sheet 52 can not be operated, so that only a single shading sheet is operated in the process of adjusting the closing of the light through hole 411, and the control precision is ensured.
The reverse linkage structure is as follows: the follow-up light blocking sheet has a return protrusion 63 on one side of the hooking protrusion 62, the drive light blocking sheet 53 is also provided with a return protrusion 63, the direction of protrusion of the return protrusion 63 is opposite to that of the hooking protrusion 62, and the hooking protrusion 62 is provided with an insertion groove 64 for inserting the return protrusion 63. When the light-passing holes 411 are enlarged, the light-shielding sheets 53 are driven to rotate first, and in the rotation process, due to the friction force between the poking convex strips 61 and the light-shielding sheets, the light-shielding sheets 53 are only driven to rotate singly until the poking convex strips 63 of the light-shielding sheets 53 touch the poking convex strips 62 of the following light-shielding sheets 52 at the next stage, and the poking convex strips 63 are embedded into the embedding grooves 64 of the poking convex strips 62, and the light-shielding sheets 53 are driven to rotate continuously at the moment, so that the laminated driving light-shielding sheets 53 and the following light-shielding sheets 52 drive the following light-shielding sheets 52 to rotate one by one to be folded.
The rotation of the driving light shielding plate 53 is controlled by the driving ring 42, the driving ring 42 is rotationally connected with the end of the light modulation barrel, a gear path is arranged at the outer side of the driving ring 42, the driving gear 31 meshed with the gear path is driven by the servo motor 3, the diameter of the driving gear 31 is far smaller than that of the driving ring 42, and the rotation angle of the driving ring 42 is controlled more finely by driving the large gear through the small gear. The inner ring surface of the driving ring 42 is provided with uniformly spaced clamping grooves 421, and the arc-shaped side of the driving light shielding sheet 53 is provided with tooth blocks 531 matched with the clamping grooves 421. The arc side of the driving shading sheet 53 is provided with a chute 532, the chute 532 is matched with a tooth block 531, a ferromagnetic coating 534 is arranged at the bottom of the chute 532, an electromagnet is arranged in the tooth block 531, a spring 533 which drives the tooth block 531 to extend outwards is arranged between the tooth block 531 and the bottom of the chute 532, the power-on/off of the electromagnet is controlled by a control circuit, when the electromagnet is powered on, the tooth block 531 is attracted with the ferromagnetic coating 534, and the tooth block 531 is retracted into the chute 532. Thus, when the driving ring 42 is required to drive the driving light shielding sheet 53, the control circuit controls the electromagnet to be powered off, and the control circuit can be realized by a simple on-off circuit, and the on-off of the control circuit is realized by a button arranged outside the light source device 2. Here, the tooth block 531 is provided with a bidirectional inclined plane, an abutting inclined plane matched with the bidirectional inclined plane of the tooth block 531 is arranged in the clamping groove 421, and when the driving ring 42 circumferentially applies a rotating force to the driving shading sheet 53, an unlocking force exists between the tooth block 531 and the clamping groove 421, so that the tooth block 531 and the clamping groove 421 form slipping, and the unlocking force is larger than the friction force between the follow-up shading sheet 52 and the fixed shading sheet 51. In this way, after all the light shielding sheets are unfolded or folded, the driving light shielding sheets 53 cannot move, and at this time, if the servo motor 3 still rotates with the driving ring 42, the tooth blocks 531 can slide between the clamping grooves 421 through the clamping structure, so as to avoid damage of the light modulation device caused by overdriving.
