Novel rotary fast-assembly interface device

Abstract

The invention relates to the technical field of photographic equipment, in particular to a novel rotary fast-assembly interface device. The device comprises a mounting female seat and a connecting piece which are used for interlocking, wherein the mounting female seat is provided with a clamping jaw and a locking device, the connecting piece is provided with a buckle, and the buckle is matched with the clamping jaw to achieve axial interlocking. The locking device comprises a positioning pin and a pressure spring, wherein the positioning pin extends out of the mounting female seat under the support of the pressure spring. The connecting piece is further provided with a limiting hole, an inclined face and a receding position, wherein the depth of the receding position is larger than the height of the positioning pin extending out of the mounting female seat; and the connecting piece rotates after being aligned with the mounting female seat, and the positioning pin can sequentially enterthe limiting hole along the receding position and the inclined face. Due to the fact that the receding position has a certain length, before the positioning pin enters the area of the inclined face,the buckle and the clamping jaw are partially staggered, so that when the inclined face presses down the positioning pin, the acting force generated by the pressure spring on the connecting piece is completely offset by the mounting female seat, and it is guaranteed that a user can rapidly install the connecting piece and the mounting female seat in a labor-saving mode.

Description

technical field [0001] The invention relates to the technical field of photographic equipment, in particular to a novel rotary quick-installation interface device that assists in converting a lens to realize quick assembly and disassembly. Background technique [0002] In underwater photography and photography, a waterproof lens barrel for protecting the camera lens is mostly installed on the waterproof casing of the camera, so that the underwater photographer can install a conversion lens with a specific function on the front end of the waterproof lens barrel to complete the shooting composition and framing. Such as super wide-angle lens or macro conversion lens and so on. Among them, the threaded connection is mostly used between the waterproof lens barrel and the conversion lens, that is, the inner side of the waterproof lens barrel is provided with internal threads, and the outer side of the conversion lens is provided with external threads. After rotating the conversion...

AI Technical Summary

Problems solved by technology

This connection method requires a certain amount of time and patience to install and remove the conversion lens, which can easily affect the photographer's creation

For example, if the screw is too tight, it may not be able to be disassembled at critical moments; or if it is not screwed enough, it will shake during use and worry about falling off... On the other hand, the casing of the waterproof lens barrel and conversion lens is mostly made of aluminum alloy and hardened High-quality anodized surface treatment, repeated disassembly and assembly can easily cause wear and fall off of the thread and oxide layer, thus affecting the service life of the product

What's more serious is that when operating underwater, it will also be disturbed by sand and stones, resulting in accelerated thread wear and failure

[0003] For this reason, the patent document CN 206710779 U designs a quick-release interface device to solve the above-mentioned problems of cumbersome assembly and disassembly and thread wear, but the quick-release interface device also has defects
