A locking structure of an astronomical telescope mirror cell with anti-loosening pad

Abstract

This utility model discloses a telescope ferrule locking structure with an anti-loosening washer, comprising an upper ferrule, a lower ferrule, and a ferrule handwheel. The upper and lower ferrules are connected on one side by a hinge and on the other side by the ferrule handwheel. The ferrule handwheel has a thread that mates with the upper end of a tensioning screw. The middle part of the tensioning screw has a smaller diameter than the upper part, and the lower part of the tensioning screw is connected to the lower ferrule via a pivot pin. The lower part of the ferrule handwheel is connected to a handwheel washer via a groove. The lower diameter of the connecting hole inside the ferrule handwheel is enlarged, and the thread in the middle of the handwheel washer mates with the upper end of the tensioning screw. This telescope ferrule structure prevents scratching the ferrule when the handwheel is used to secure it. Furthermore, when the handwheel is unscrewed, the ferrule handwheel and handwheel washer ensure that part of the tensioning screw's thread remains in the ferrule handwheel, preventing it from easily coming off. This achieves the effect that the ferrule handwheel will not easily fall off after being fully unscrewed, but will continue to hang on the tensioning screw.

Description

Technical Field

[0001] This utility model relates to the field of astronomical telescopes, and in particular to a telescope lens clamp locking structure with anti-loosening pads. Background Technology

[0002] The telescope ferrule is a key component for fixing the telescope tube to the support. However, the existing ferrules are directly connected by a handwheel, which can easily scratch the surface of the ferrule. Furthermore, when unscrewing the handwheel, it is easy to unscrew the entire handwheel and cause it to fall off. Summary of the Invention

[0003] To solve the above problems, this utility model provides a telescope ferrule locking structure with an anti-loosening washer, consisting of an upper ferrule, a lower ferrule, and a ferrule handwheel; the upper and lower ferrules are connected on one side by a hinge and on the other side by a ferrule handwheel; the ferrule handwheel has a thread inside that mates with the upper end of a tensioning screw, the middle part of the tensioning screw has a smaller diameter than the upper part, and the lower part of the tensioning screw is connected to the lower ferrule by a pivot pin; the lower part of the ferrule handwheel is connected to a handwheel washer through a groove, the lower diameter of the connecting hole inside the ferrule handwheel is enlarged, and the thread in the middle of the handwheel washer mates with the upper end of the tensioning screw. The pivot pin passes through the connecting hole on the lower lens clamp and the connecting hole at the bottom of the tensioning screw to connect the tensioning screw and the lower lens clamp. A barb is provided on the handwheel washer and the lens clamp handwheel to prevent the handwheel washer from falling off when the lens clamp handwheel is loosened. A handwheel washer is placed between the lens clamp handwheel and the upper lens clamp to prevent scratching the lens clamp surface. The upper section of the tensioning screw is threaded, while the middle section is smaller than the upper section. The smallest hole in the handwheel washer has the same thread specification as the tensioning screw, but the hole diameter is slightly larger than the minimum diameter of the thread, allowing the middle section to pass freely. The upper section thread requires thread matching. This allows the tension screw to pass through; at the same time, a hole is made in the lower section of the mirror clamp handwheel to form a cavity, allowing the threaded part of the tension screw to exist freely in it. When the thread in the mirror clamp handwheel is completely tightened, the threaded part of the tension screw will continue to remain in the mirror clamp handwheel. However, the threaded part of the tension screw cannot easily pass through the handwheel washer, and the handwheel washer is interlocked with the mirror clamp handwheel, so that the threaded part of the tension screw can remain in the mirror clamp handwheel and cannot easily come out. Ultimately, this achieves the effect that the mirror clamp handwheel will not easily fall off after being completely tightened, but will continue to hang on the tension screw.

[0004] The above-mentioned technical solution of this utility model has the following beneficial technical effects: Through the telescope hoop structure, the hoop can be prevented from being scratched when the handwheel is fixed. At the same time, when the handwheel is unscrewed, the hoop handwheel and the handwheel washer make part of the thread of the tensioning screw remain in the hoop handwheel and cannot be easily removed. This achieves the effect that the hoop handwheel will not easily fall off after it is completely unscrewed, but will continue to hang on the tensioning screw. Attached Figure Description

[0007] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0008] like Figure 1-4As shown, an astronomical telescope clamp locking structure with anti-loosening pads consists of an upper clamp 6, a lower clamp 1, and a clamp handwheel 5. The upper clamp 6 and the lower clamp 1 are connected on one side by a hinge and on the other side by the clamp handwheel 5. The clamp handwheel 5 has a thread inside that mates with the upper end of a tensioning screw 3. The middle part of the tensioning screw 3 has a smaller diameter than the upper part. The lower part of the tensioning screw 3 is connected to the lower clamp 1 through a pivot pin 2. The lower part of the clamp handwheel 5 is connected to a handwheel washer 4 through a slot. The lower diameter of the connecting hole inside the clamp handwheel 5 is enlarged, and the thread in the middle of the handwheel washer 4 mates with the upper end of the tensioning screw 3. The pivot pin 2 passes through the connecting hole on the lower lens clamp 1 and the connecting hole at the bottom of the tensioning screw 3 to connect the tensioning screw 3 and the lower lens clamp 1. A barb is provided on the handwheel washer 4 and the lens clamp handwheel 5. The handwheel washer 4 will not fall off after the lens clamp handwheel 5 is loosened. The handwheel washer 4 is placed between the lens clamp handwheel 5 and the upper lens clamp 6 to prevent scratching the lens clamp surface. The upper section of the tensioning screw 3 is threaded, while the middle section is not threaded and is smaller than the upper section. The minimum hole of the handwheel washer 4 is provided with the same thread specification as the tensioning screw 3, but the hole diameter is slightly larger than the minimum hole diameter of the thread, so that the middle section can pass freely, while the upper section thread requires... The threads must be aligned to allow passage; simultaneously, a hole is made in the lower section of the mirror clamp handwheel 5 to form a cavity, allowing the threaded portion of the tensioning screw 3 to exist freely within it. When the threads in the mirror clamp handwheel 5 are completely tightened, the threaded portion of the tensioning screw 3 will remain in the mirror clamp handwheel 5. However, the threaded portion of the tensioning screw 3 cannot easily pass through the handwheel washer 4, and the handwheel washer 4 is interlocked with the mirror clamp handwheel 5, causing the threaded portion of the tensioning screw 3 to remain in the mirror clamp handwheel 5 and not easily come out. Ultimately, this achieves the effect that the mirror clamp handwheel 5 will not easily fall off after being completely tightened, but will continue to hang on the tensioning screw.
