Description

Technical Field

[0001] This application relates to the technical field of fiber optic test instruments, and in particular to an integrating sphere quick-release interface. Background Technology

[0002] Integrating spheres play a crucial role in numerous scientific research and industrial production fields, including optical measurement and spectral analysis. They reflect light multiple times to achieve a uniform light field distribution, making them key measurement tools in photometry and radiometry. With continuous technological advancements, the demands for ease of use and measurement accuracy of integrating spheres are increasing. Different experimental and production scenarios require frequent replacement or maintenance of integrating spheres, necessitating highly efficient interface design. A well-designed interface not only improves work efficiency and reduces time and labor costs associated with equipment disassembly and assembly but also ensures the stability of the integrating sphere during connection, thereby guaranteeing the accuracy and reliability of measurement results. Given this trend, optimizing integrating sphere interface technology has become a focus of industry attention.

[0003] In the past, common methods for connecting integrating spheres to other equipment included threaded connections and snap-fit ​​connections. Threaded connections involve machining matching threads on both the integrating sphere interface and the matching equipment, then tightly connecting them by rotation. This method ensures connection stability to a certain extent, preventing loosening and air leakage. Snap-fit ​​connections utilize a flexible snap-fit ​​structure to quickly clamp the integrating sphere interface to the equipment; this is relatively simple and time-saving. Additionally, adhesive bonding is used to fix the interface, providing a more secure connection, but making disassembly difficult and potentially damaging to the equipment. Furthermore, some manufacturers use bolts and nuts, securing the integrating sphere interface to the equipment with multiple bolts. While this provides high connection strength, the disassembly and assembly process is cumbersome, requires tools, and is prone to uneven connections due to inconsistent bolt tightening.

[0004] However, these existing connection methods have significant drawbacks. Threaded connections are prone to thread wear during frequent disassembly and assembly, leading to decreased connection stability, and the tightening process is also time-consuming. While snap-fit ​​connections are simple to operate, the elasticity of the snaps is prone to fatigue, and after long-term use, they may become loose, affecting the normal operation of the integrating sphere. Adhesive connections are difficult to disassemble once connected, hindering equipment maintenance and replacement. Bolt and nut connections suffer from low disassembly and assembly efficiency, requiring each bolt to be tightened or loosened individually, wasting considerable time and effort. Furthermore, existing connection methods struggle to achieve precise positioning, potentially leading to positional deviations of the integrating sphere after installation, affecting measurement accuracy. Utility Model Content

[0005] To improve the efficiency of integrating sphere assembly and disassembly, this application provides a quick-release interface for integrating spheres.

[0006] The quick-release interface for an integrating sphere provided in this application adopts the following technical solution:

[0007] A quick-release interface for an integrating sphere includes a base and an integrating sphere interface. The integrating sphere interface is detachably mounted on the base via a mounting component. The mounting component has a mounting groove, and the base has a mounting ring that detachably engages with the mounting groove. The mounting component has a mounting groove, and the groove wall has multiple locking pins. The base has a mounting ring that detachably engages with the mounting groove. The end of the mounting ring extends to a baffle, and the baffle has a notch corresponding to the locking pins. The locking pins can pass through the notch and be positioned between the baffle and the base by rotating the mounting component.

[0008] By adopting the above technical solution, locking can be completed by rotating a certain angle after the pin passes through the notch of the baffle, which greatly simplifies the operation steps compared to traditional threaded connections. The mechanical limiting cooperation between the baffle and the pin effectively prevents accidental loosening after installation, while the overall structure is compact, significantly improving disassembly and assembly efficiency and ease of use.

[0009] Preferably, the mounting component is provided with a plurality of positioning components along the circumference of the mounting groove, the positioning components including positioning beads, and the positioning beads are rotatably disposed on the mounting component; the base is provided with a plurality of positioning grooves along the circumference of the mounting ring; when the mounting component rotates relative to the base, the positioning beads are confined within the positioning grooves.

[0010] By adopting the above technical solution, multiple positioning elements with positioning beads are set around the mounting groove, which cooperate with the positioning groove on the base to provide reliable tactile feedback for the rotation locking process. This design not only ensures the accuracy of the mounting element rotating into place, but also significantly enhances the circumferential stability of the interface through multi-point positioning.

[0011] Preferably, the notch on the baffle and the positioning groove on the base are offset from each other along the circumferential direction of the positioning ring. When the pin is aligned with the notch, the positioning element does not correspond to the positioning groove; however, when the mounting element is rotated to disengage the pin from the notch, the positioning element corresponds to the positioning groove.

[0012] By adopting the above technical solution, the circumferentially misaligned arrangement of the notch and the positioning groove forms a clear three-stage locking process. This design first ensures that the pin is aligned with the notch before insertion, then it must be rotated to a specific position to align the positioning component with the positioning groove, and finally, locking is completed. This step-by-step mechanism effectively prevents misjudgment of installation completion when not fully locked, greatly improving the reliability and safety of installation.

[0013] Preferably, the positioning element further includes a mounting cylinder and a spring. The mounting cylinder is installed inside the mounting element, and the spring is compressed and installed inside the mounting cylinder and abuts against the positioning ball. The positioning ball protrudes from the mounting cylinder and rolls into the positioning groove.

[0014] By adopting the above technical solution and using a spring-preloaded positioning ball design, a continuous and stable elastic positioning force is ensured.

[0015] Preferably, the outer side wall of the mounting component is provided with anti-slip texture.

[0016] By adopting the above technical solution, the friction can be increased by setting anti-slip texture, thereby playing an anti-slip role.

[0017] Preferably, the plurality of pins are distributed at equal angles along the circumferential direction of the mounting groove wall.

[0018] By adopting the above technical solution, the arrangement of multiple pins distributed at equal angles along the circumference of the mounting groove makes the force distribution more uniform and reasonable.

[0019] Preferably, the plurality of positioning grooves are evenly distributed along the circumference of the mounting ring.

[0020] By adopting the above technical solution, precise positioning with multiple selectable angles is achieved by evenly distributing the positioning grooves along the circumference of the installation ring.

[0021] Preferably, the outer wall of the mounting ring is provided with a limiting plate, and the locating pin is slidably connected between the baffle and the limiting plate.

[0022] By adopting the above technical solution, the movement of the pin can be guided and limited, further improving the stability of the detachable installation of the mounting parts and the base.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The mounting component can be detachably installed on the base. Through the cooperation of the pin and notch, the baffle and the positioning ball and the positioning groove, the quick-release interface of the integrating ball can be quickly disassembled and assembled, improving work efficiency and reducing the time and labor costs of equipment disassembly and assembly;

[0025] 2. By using positioning beads to enter the positioning slot, precise positioning can be achieved during the installation of the integrating sphere quick-release interface, avoiding positional deviation of the integrating sphere after installation and affecting measurement accuracy.

[0030] The following combination Figures 1-3 This application will be described in further detail.

[0031] This application discloses a quick-release interface for an integrating sphere.

[0032] Reference Figure 1 An integrating sphere quick-release interface includes a base 1 and an integrating sphere interface 2, wherein the integrating sphere interface 2 is detachably mounted on the base 1 via a mounting component 3.

[0033] Reference Figure 2 The mounting component 3 is cylindrical in shape, and a mounting groove 31 is formed on the end face of the mounting component 3 near the base 1. The mounting groove 31 is cylindrical in shape, and its axis coincides with the axis of the mounting component 3. Multiple locking pins 32 are provided on the groove wall of the mounting groove 31. The locking pins 32 are equidistantly spaced along the circumference of the mounting groove 31, and the included angle between adjacent locking pins 32 is equal. In this embodiment, two locking pins 32 are provided, and the two locking pins 32 are located on the diameter of the circular cross-section of the mounting groove 31. In other embodiments, the number of locking pins 32 can be increased. The locking pins 32 can be fixed to the groove wall of the mounting groove 31 by welding or screwing. Welding makes the connection between the locking pins 32 and the mounting groove 31 more secure, while screwing facilitates the replacement and maintenance of the locking pins 32. Preferably, anti-slip textures are formed on the outer wall of the mounting component 3 along its own axial direction to facilitate stable rotation of the mounting component 3.

[0034] Reference Figure 3 The base 1 is generally rectangular, with its length parallel to the end face of the mounting body. A circular clearance hole is provided at the center of the base 1 to facilitate connection and mating between other equipment and the integrating sphere interface 2. A mounting ring 5 is integrally formed along the circumference of the clearance ring on the base 1, positioned close to the mounting body. The mounting ring 5 is circular and can be inserted into the mounting groove 31. When the mounting ring 5 and the mounting groove 31 are inserted and mated, the axis of the mounting ring 5 coincides with the axis of the mounting component 3.

[0035] A baffle 51 extends outward from the end of the mounting ring 5 away from the base 1, away from the center of the base 1. The baffle 51 has notches 52 corresponding to the number of locating pins 32. The opening width of the notches 52 is greater than the maximum cross-sectional size of the locating pins 32, and the notches 52 extend radially along the baffle 51. When the mounting member 3 approaches the base 1, rotating the mounting member 3 allows multiple locating pins 32 to correspond one-to-one with the notches 52. As the mounting member 3 continues to approach the base 1, the locating pins 32 can pass through the notches 52. Further rotation of the mounting member 3 allows the locating pins 32 to be positioned between the baffle 51 and the base 1. Preferably, a limiting plate 53 is also provided on the outer wall of the mounting ring 5 along the movement trajectory of the locating pins 32. When the mounting member 3 rotates relative to the base 1, the locating pins 32 are slidably connected between the baffle 51 and the limiting plate 53, ensuring the accurate movement trajectory of the locating pins 32.

[0036] Reference Figure 2 A plurality of positioning elements 4 are mounted on the end face of the mounting component 3 near the base 1. The positioning elements 4 include a mounting cylinder 42, positioning beads 41, and a spring. Mounting holes 33 are evenly distributed circumferentially along the edge of the mounting groove 31 on the end face of the mounting component 3. In this embodiment, four mounting holes 33 are provided. The mounting cylinder 42 is cylindrical in shape, and the mounting sleeve is installed in the mounting hole 33 via a threaded structure. The spring is located inside the mounting cylinder 42, with its compression direction parallel to the axis of the mounting component 3, and the spring is always in a compressed state. Part of the positioning beads 41 is located inside the mounting cylinder 42, and a small portion is located outside the mounting cylinder 42. The end of the spring near the base 1 abuts against the positioning beads 41, and the elastic action of the spring enables the positioning beads 41 to be rolled and installed on the mounting component 3.

[0037] Reference Figure 3 The base 1 has evenly spaced positioning grooves 11 along the circumference of the mounting ring 5, and the number of positioning grooves 11 corresponds to the number of positioning components 4. The notch 52 and the positioning grooves 11 are offset. When the locating pin 32 passes through the notch 52, the positioning ball 41 does not correspond to the positioning groove 11. As the mounting component 3 rotates, the locating pin 32 moves away from the notch 52, and multiple positioning balls 41 can enter the positioning groove 11, thus achieving positioning. The positioning balls 41 are elastically supported on the end face of the mounting component 3 by springs. The spring compression stroke matches the depth of the positioning groove 11, ensuring positioning stability when the positioning balls 41 enter the positioning groove 11, and also facilitating subsequent disassembly.

[0038] Preferred, Reference Figure 1 The end face of the mounting component 3 away from the base 1 is also provided with an upward marking, which serves as an indicator and facilitates subsequent installation work by the staff.

[0039] The implementation principle of the quick-release interface for an integrating sphere according to this application embodiment is as follows: During installation, the mounting part 3 is first brought close to the base 1. The mounting part 3 is rotated so that the locking pin 32 aligns with the notch 52 on the baffle 51. After the locking pin 32 passes through the notch 52, the mounting part 3 is rotated again so that the locking pin 32 is positioned between the baffle 51 and the base 1. At the same time, the positioning ball 41 enters the positioning groove 11 to achieve positioning. During disassembly, the mounting part 3 is rotated in the opposite direction so that the locking pin 32 aligns with the notch 52 again, and the mounting part 3 can be separated from the base 1. Compared with traditional connection methods, such as threaded connection, snap-fit ​​connection, adhesive and bolt-nut connection, this interface avoids problems such as easy wear of threads, elastic fatigue of snap-fit, difficulty in disassembling adhesive, and low efficiency of bolt-nut disassembly and assembly. It greatly improves the efficiency and accuracy of integrating sphere disassembly and assembly, which is beneficial to equipment maintenance and replacement. At the same time, it also ensures the positional accuracy of the integrating sphere after installation and improves the accuracy of measurement.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
