[0023] The utility model will be described in detail below with reference to the accompanying drawings. Figure 1As shown: the rigid endoscope assembly and image adjustment device described in this embodiment includes an optical assembly mechanism 2 and an optical image adjustment mechanism 3 which are correspondingly installed on the base plate 1 and are distributed in a right angle shape; the optical assembly mechanism 2 includes a fine-tuning platform 21 which can be translated up and down, left and right and horizontally rotated, a locking mechanism 22 arranged at the upper end of the fine-tuning platform 21, a fitting platform 23 fixed on the base plate 1 on one side of the fine-tuning platform 21 for fitting glasses for the fine-tuning platform 21, and a horizontal auxiliary device 24 fixed on the base plate 1 on the other side of the fine-tuning platform 21 and perpendicular to the fitting platform 23, the upper surface of the fitting platform 23 is provided with a lens groove for placing a lens, preferably the lens groove is set as a V-shaped groove, and the lens groove is set corresponding to the locking mechanism 22; the optical image adjustment mechanism 3 includes an image adjustment platform 31 which can be translated forward and backward, left and right and vertically rotated and is arranged on the extension line of the horizontal auxiliary device 24 and the fine-tuning platform 21, and an optical display mechanism 32 installed on the image adjustment platform 31.
[0024] The rigid endoscope assembly and image adjustment device described in this embodiment integrates optical assembly and image adjustment, which not only improves the efficiency of the optical assembly of the rigid endoscope; it also performs precise position adjustment through the fine-tuning pan-tilt table 21 and the image adjustment pan-tilt table 31 to offset the processing errors of the parts of the rigid endoscope, improve the consistency of the rigid endoscope assembly, and further improve the integrity and image quality of the optical performance of the rigid endoscope; the setting of the glasses fitting platform 23 provides an assembly channel for the lens, which not only avoids the situation where the lens falls or is damaged due to frequent movement, but also avoids manual assembly, thereby effectively avoiding secondary contamination of the optical lens.
[0025] When the optical assembly mechanism 2 is used to assemble a rigid endoscope, the fine-tuning platform 21 is first adjusted to the initial position, that is, the position where the locking mechanism 22 of the fine-tuning platform 21 is relative to the horizontal assistant 24, and then the locking mechanism 22 is opened, and the rigid endoscope is slid into the assembly, and the rigid endoscope is adjusted to maintain an inverted horizontal position through the horizontal assistant 24, and then the locking mechanism 22 is closed to lock the rigid endoscope, and then the optical lenses are arranged in the lens grooves of the fitting platform 23, and the fine-tuning platform 21 is rotated 90 degrees, that is, the position where the locking mechanism 22 is relative to the fitting platform 23, and the position is adjusted so that the hole of the optical channel of the rigid endoscope is aligned with the lens groove, and then the optical lenses arranged in the lens grooves are pushed into the optical channel of the rigid endoscope with a push rod tool to complete the assembly of the optical lenses.
[0026] As a further improvement of the above technical solution, the base plate 1 is a rectangular structure formed by snapping together two sub-base plates 1, and the optical assembly mechanism 2 and the optical image adjustment mechanism 3 are respectively installed on one of the sub-base plates 1, so that the optical image adjustment mechanism 3 and the optical assembly mechanism 2 can be disassembled to improve the overall portability.
[0027] like Figure 2 As shown, the locking mechanism 22 includes a fixing seat 221 fixed to the upper end of the fine-tuning pan / tilt head 21, a convex fixing block 222 arranged at the upper end of the fixing seat 221, a movable block 223 sliding into the groove of the fixing block 222, and a locking screw 224 screwed downward from the upper end of the fixing block 222 and pressed against the screw hole of the movable block 223.
[0028] Preferably, the movable block 223 fits tightly into the V-shaped endoscope groove on the upper surface of the fixing seat 221 through the spring 225 assembled thereon.
[0029] In order to facilitate installation, as a preferred embodiment of the above technical solution, the horizontal auxiliary device 24 includes an up-and-down sliding track 241 fixed on the base plate 1 and a horizontal block 242 installed on the up-and-down sliding track 241. Figure 2 As shown, the height of the horizontal block 242 is adjusted by the up-and-down sliding track 241 to fit closely to the rigid endoscope, wherein a limiting groove for inserting the rigid endoscope is also provided at the upper end of the horizontal block 242 .
[0030] like Figure 3 As shown, the assembly of the optical image adjustment mechanism 3 is as follows: first, the front and rear slide rails 311 are fixed to the base plate 1, and the left and right slide rails 313 are assembled to the upper ends of the front and rear slide rails 311 through the first adapter slider 312 to form an X-axis and Y-axis adjustable component, and then the vertical rotation pan-tilt head 315 is assembled to the left and right slide rails 313 through the second adapter slider 314, and then the support plate 321 is assembled to the vertical rotation pan-tilt head 315 to complete the assembly of the image adjustment pan-tilt head 31; then, the backlight panel 322 is assembled to the support plate 321, and two plug-in plates 323 are assembled to both sides of the backlight panel 322, and the resolution panel 324 is inserted between the two plug-in plates 323 so that the resolution panel 324 is located at the front end of the backlight panel 322 to complete the assembly of the optical display mechanism 32.
[0031] When the optical image adjustment mechanism 3 is used for adjustment, the fine-tuning platform 21 is first rotated 90 degrees, and the rigid endoscope fixed thereon is opposite to the optical image adjustment mechanism 3. The rotation angle of the vertical rotation platform 315 is adjusted so that the angle of the resolution plate 324 installed thereon is parallel to the inclined surface of the rigid endoscope. Then the left and right slide rails 313, the front and rear slide rails 311 and the fine-tuning platform 21 are adjusted to align the pattern of the resolution plate 324 with the center of the optical channel of the rigid endoscope, and make the resolution plate 324 parallel to the inclined surface of the rigid endoscope. The relative distance between the front objective lens of the rigid endoscope and the resolution plate 324 is maintained within the optical design distance range of 1 to 5 mm. Within this range, the resolution plate 324 area can be observed by naked eyes in the optical channel of the rigid endoscope to present a complete image. At the same time, the backlight brightness of the backlight plate 322 is appropriately adjusted according to the environment. Then, the eyepiece of the rigid endoscope is assembled on the rigid endoscope, and the eye is observed through the eyepiece to see whether the pattern of the resolution plate 324 is clear, and the eyepiece of the rigid endoscope is adjusted until the image is clear.
[0032] As a further improvement of the above technical solution, an openable and closable dust shield (not shown in the figure) is provided at the upper end of the glasses fitting platform 23 for covering the lens slot, which can protect the lens slot when idle to prevent dust from falling into the lens slot, thereby further avoiding contamination of the lens.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
