Technical Field
[0001] This utility model relates to the field of endoscope technology, specifically to an endoscope optical performance testing device. Background Technology
[0002] In the field of existing endoscopic technology, the testing of endoscopic optical performance faces numerous challenges. Traditional endoscopic optical performance testing devices have significant shortcomings in fixing the endoscope. On the one hand, it is difficult to achieve efficient and stable fixation of the front and rear ends of the endoscope eyepiece. During the testing process, the endoscope is prone to back-and-forth movement, which not only affects the accuracy of the test but may also lead to deviations in the test results, making it impossible to accurately determine whether the endoscope's optical performance is up to standard. For example, when testing some precision endoscopes, even slight back-and-forth displacement can cause blurring or distortion of the image on the observed display screen, interfering with the judgment of optical performance.
[0003] On the other hand, even with initial fixation, the endoscope still exhibits wobbling. This makes it difficult to guarantee stable observation and imaging during the testing process. Whether through manual observation or viewing images on a display screen using a digital camera, wobbling leads to inaccurate results, making it impossible to clearly determine whether the endoscope's optical performance meets the usage requirements. Moreover, traditional fixation methods are often complex, inconvenient to operate, and consume significant time and effort, reducing testing efficiency and failing to meet the practical need for rapid and accurate testing of endoscope optical performance. Therefore, we have introduced an endoscope optical performance testing device. Summary of the Invention
[0004] The purpose of this invention is to provide an endoscope optical performance testing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An endoscope optical performance testing device includes a base, a fixing seat is provided at the top of one end of the base, a mounting through hole is provided on the fixing seat, and a front limiting component and a rear limiting component are respectively provided at both ends of the mounting through hole, the front limiting component and the rear limiting component are respectively fixed from the front and rear ends of the endoscope eyepiece;
[0007] The rear limiting component is also provided with clamping mechanisms at equal intervals. While the rear limiting component drives the front limiting component to be screwed and locked together with the mounting through hole, the clamping mechanism clamps the outer wall surface of the endoscope eyepiece.
[0008] Preferably, a display screen is mounted on the top of the other end of the base via a bracket, and an auxiliary bracket is also provided on the upper end of the base between the fixed base and the bracket, through which the endoscope tube at the end of the endoscope eyepiece extends.
[0009] Preferably, the front limiting assembly includes a front limiting external threaded cylinder screwed into the front end of the mounting through hole and a limiting ring fixed on the front wall of the front limiting external threaded cylinder;
[0010] The rear limiting assembly includes a rear limiting cylinder and a rear external threaded ring disposed on the outer side of the front end of the rear limiting cylinder. A snap-fit post disposed at the front end of the rear external threaded ring is used to insert into the corresponding insertion hole at the rear end of the front limiting external threaded cylinder, so as to realize that the rear external threaded ring and the front limiting external threaded cylinder are locked synchronously with the mounting through hole.
[0011] Preferably, the rear outer wall of the rear limiting cylinder is provided with anti-slip protrusions at equal intervals, and the rear middle of the rear end of the rear limiting cylinder is provided with a through hole.
[0012] Preferably, the rear limiting cylinder is provided with rectangular slots at equal intervals, and the outer side wall of the rectangular slots is symmetrically connected with vertical plates;
[0013] The clamping mechanism includes a rotating arm that is movably connected between two corresponding sets of upright plates by a pin, a contact ball fixed at the front end of the rotating arm by a connecting arm, and an arc-shaped clamping seat that extends into the rear limiting cylinder through a rectangular slot and is then fixed.
[0014] The inner wall of the mounting through hole is also provided with a tapered ring seat. The tapered ring seat is located behind the rear external threaded ring, and the outer diameter of the tapered ring seat decreases from front to back. The contact ball abuts against the outer wall of the tapered ring seat.
[0015] Compared with the prior art, the beneficial effects of this utility model are: by tightening and fixing the rear limiting component, this utility model can simultaneously drive the tightening and fixing of the front limiting component, thereby synchronously causing the front and rear limiting components to clamp and limit the front and rear ends of the endoscope eyepiece respectively, thus preventing the endoscope from moving back and forth, and preparing for subsequent testing of the optical performance of the endoscope.
[0016] Furthermore, when the rear limiting assembly is tightened and fixed, it moves forward, and the contact ball abuts against the outer wall of the conical ring seat. This causes the connecting arm, rotating arm, and arc-shaped clamp to rotate around the pin. The arc-shaped clamp is then clamped onto the outer wall surface of the endoscope eyepiece, preventing the endoscope from shaking and preparing it for subsequent testing of the endoscope's optical performance. This not only enables rapid fixation of the endoscope but also achieves a good fixation effect. Attached Figure Description

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example:
[0030] Please see Figure 1-10 This utility model provides a technical solution:
[0031] An endoscope optical performance testing device includes a base 4, a fixed seat 2 is provided at the top of one end of the base 4, and a display screen 7 is mounted on the top of the other end of the base 4 via a bracket 6. An auxiliary bracket 5 is also provided at the upper end of the base 4 between the fixed seat 2 and the bracket 6. The endoscope tube 8 at the end of the endoscope eyepiece 3 extends through a reserved hole provided on the auxiliary bracket 5.
[0032] After the endoscope is installed and fixed, various images are displayed on the display screen 7. Then, the images are observed using the endoscope eyepiece 3. The images displayed on the display screen 7 can be observed through the endoscope eyepiece 3, the endoscope tube 8, and the eyepiece at the rear end of the endoscope tube 8. If the images are clearly visible in the endoscope eyepiece 3, it means that the optical performance of the endoscope is qualified and meets the usage requirements. If the images are not clearly visible in the endoscope eyepiece 3, it means that the optical performance of the endoscope is unqualified and does not meet the usage requirements.
[0033] When observing images through the endoscope eyepiece 3, manual observation or taking pictures of the images through the endoscope eyepiece 3 with a digital camera can be used.
[0034] The mounting base 2 has a mounting through hole 202. The two ends of the mounting through hole 202 are respectively provided with a front limiting component and a rear limiting component. The front limiting component and the rear limiting component are fixed from the front and rear ends of the endoscope eyepiece 3, respectively.
[0035] The front limiting assembly includes a front limiting external threaded cylinder 1 screwed into the front end of the mounting through hole 202 and a limiting ring 1001 fixed on the front end wall of the front limiting external threaded cylinder 1.
[0036] The inner diameter of the front limiting external threaded cylinder 1 is consistent with the outer diameter of the endoscope eyepiece 3 so that the endoscope eyepiece 3 can be inserted into the front limiting external threaded cylinder 1. The inner diameter of the limiting ring 1001 is smaller than the outer diameter of the endoscope eyepiece 3. After the endoscope eyepiece 3 is fixedly installed, the front end of the endoscope eyepiece 3 is in close contact with the rear end surface of the limiting ring 1001, and the limiting ring 1001 will not obstruct the observation of the endoscope eyepiece 3.
[0037] The rear limiting assembly includes a rear limiting cylinder 10 and a rear external threaded ring 104 provided on the outer side of the front end of the rear limiting cylinder 10. The locking post 105 provided at the front end of the rear external threaded ring 104 is used to insert into the corresponding insertion hole 1002 at the rear end of the front limiting external threaded cylinder 1. In this way, when the rear limiting assembly is tightened, the front limiting assembly and the rear limiting assembly can rotate together, so that the rear external threaded ring 104 and the front limiting external threaded cylinder 1 are locked synchronously with the mounting through hole 202.
[0038] After the front and rear limiting components are locked and fixed from the front and rear ends of the mounting through hole 202, the front and rear limiting components clamp and limit the front and rear ends of the endoscope eyepiece 3 (e.g., Figure 10 (The state shown).
[0039] The rear outer side wall of the rear limit cylinder 10 is provided with anti-slip protrusions 101 at equal intervals. By setting the anti-slip protrusions 101, the friction between the hand and the rear limit cylinder 10 can be increased when manually tightening or unscrewing the rear limit cylinder 10, making it convenient to quickly tighten or loosen the rear limit cylinder 10.
[0040] The rear limit cylinder 10 has a through hole 9 at the middle of its rear end, so that the rear end of the endoscope eyepiece 3 can pass through the through hole 9.
[0041] The rear limiting component is also provided with clamping mechanisms at equal intervals. When the rear limiting component drives the front limiting component to be screwed and locked together with the mounting through hole 202, the clamping mechanism clamps on the outer wall surface of the endoscope eyepiece 3.
[0042] The rear limiting cylinder 10 is provided with rectangular slots 103 at equal intervals, and the outer side wall of the rectangular slots 103 is symmetrically connected with vertical plates 102.
[0043] The clamping mechanism includes a rotating arm 11 movably connected between two corresponding sets of upright plates 102 by a pin 112, a contact ball 114 fixed at the front end of the rotating arm 11 by a connecting arm 111, and an arc-shaped clamp 113 fixed at the rear end of the rotating arm 11 after extending into the rear limiting cylinder 10 via a rectangular slot 103.
[0044] The inner wall of the mounting through hole 202 is also provided with a tapered ring seat 201. The tapered ring seat 201 is located behind the rear external threaded ring 104, and the outer diameter of the tapered ring seat 201 decreases from front to back. The contact ball 114 abuts against the outer wall of the tapered ring seat 201. This arrangement ensures that the contact ball 114 can rotate on the outer wall of the tapered ring seat 201, so as to tighten or loosen the outer wall of the rear external threaded ring 104 of the rear limiting assembly from the inner wall of the mounting through hole 202.
[0045] When the outer wall of the rear external threaded ring 104 is tightened to the inner wall of the mounting through hole 202 by the anti-slip protrusion 101, the entire rear limiting assembly moves forward relative to the mounting through hole 202. At this time, the contact ball 114 will be pressed against the outer wall of the conical ring seat 201, causing the connecting arm 111, the rotating arm 11, and the arc-shaped clamp 113 to rotate around the pin 112 as the center, until the arc-shaped clamp 113 is clamped on the outer wall surface of the endoscope eyepiece 3. This can prevent the endoscope from shaking and prepare for subsequent testing of the optical performance of the endoscope.
[0046] Specifically, during use, the mounting through hole 202 on the fixing base 2 is provided with a front limiting component and a rear limiting component at both ends. The front limiting external threaded sleeve 1 of the front limiting component is screwed into the front end of the mounting through hole 202. Its inner diameter is consistent with the outer diameter of the endoscope eyepiece 3, and the endoscope eyepiece 3 can be inserted into it, with its front end closely attached to the rear end surface of the limiting ring 1001 (the inner diameter of the limiting ring 1001 is smaller than the outer diameter of the endoscope eyepiece 3 and does not obstruct observation).
[0047] The rear external threaded ring 104 on the outer side of the front end of the rear limiting cylinder 10 of the rear limiting assembly has a locking pin 105 at its front end inserted into the insertion hole 1002 at the rear end of the front limiting external threaded cylinder 1. When the rear limiting cylinder 10 is tightened, the front limiting assembly and the rear limiting assembly rotate together, and the rear external threaded ring 104 and the front limiting external threaded cylinder 1 lock synchronously with the mounting through hole 202, thereby clamping and fixing the front and rear ends of the endoscope eyepiece 3. This prevents the endoscope from moving back and forth, preparing for subsequent testing of the optical performance of the endoscope.
[0048] When the rear external threaded ring 104 is tightened, the rear limiting assembly moves forward, and the contact ball 114 abuts against the outer wall of the conical ring seat 201, causing the connecting arm 111, the rotating arm 11, and the arc-shaped clamp 113 to rotate around the pin 112. The arc-shaped clamp 113 clamps onto the outer wall surface of the endoscope eyepiece 3 to prevent the endoscope from shaking, thus preparing for subsequent testing of the optical performance of the endoscope.
[0049] After the endoscope is fixed in place, the display screen 7 shows various images. The images on the display screen 7 can be observed through the endoscope eyepiece 3, the endoscope tube 8, and the eyepiece at the rear of the endoscope tube 8. Observation can be done manually or by taking pictures of the images through the endoscope eyepiece 3 using a digital camera. If the image is clearly visible in the endoscope eyepiece 3, the endoscope's optical performance is qualified and meets the usage requirements; if it is not clearly visible, the endoscope's optical performance is unqualified and does not meet the usage requirements.
[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
