Telescopic spontoon

Abstract

The invention provides a telescopic spontoon, and relates to the technical field of antiriot equipment. The telescopic spontoon comprises an outer tube, a medium tube, a rear tube, a medium tube locking mechanism, a rear tube locking mechanism, an unlocking mechanism, and a pounding head. The medium tube locking mechanism comprises a first drum butterfly, a second drum butterfly, and a pair of drum butterfly springs. The first drum butterfly is slidably cooperated with a first drum butterfly sliding groove. The side of the first drum butterfly, facing a medium tube cavity, is provided with a first drum butterfly lug. The central position of the first drum butterfly lug is provided with a first drum butterfly unlocking hole. The right side of the first drum butterfly is provided with a first drum butterfly anti-shock groove. One side of the second drum butterfly, facing the medium tube cavity, is provided with a second drum butterfly lug. The second drum butterfly lug is provided with a second drum butterfly unlocking hole on the position corresponding to the first drum butterfly unlocking hole. The right side of the second drum butterfly is provided with a second drum butterfly anti-shock groove. The pair of drum butterfly springs are supported between the first drum butterfly and the second drum butterfly. The left end of the medium tube and the right end of the outer tube are ensured to be reliably locked, and the left end of the rear tube and the right end of the medium tube can also be reliably locked.

Description

technical field [0001] The invention belongs to the technical field of anti-riot equipment, and in particular relates to a retractable baton. Background technique [0002] The aforementioned retractable baton is one of the police equipment worn by the public security police in our country, especially the public security police and armed police. Because it is a telescopic structure and is mostly used in the thrown state, it is also called "throwing stick" or " Knotty stick". Usually three, but not limited to three. [0003] The technical information of all telescopic batons can be seen in the published Chinese and foreign patent documents, such as CN104457414A (a telescopic baton that can improve assembly convenience and stability), CN105865259A (a positioning control mechanism for a telescopic baton), CN101598521A (a telescopic baton without Grade telescopic baton), CN200734676U (telescopic baton) and US Patent US20130150167 (telescopic baton), etc. [0004] As known in t...

AI Technical Summary

Problems solved by technology

However, the telescopic batons in the prior art including the above-mentioned patent generally have the following disadvantages: abnormal retraction often occurs when the end of the baton in an extended state impacts on doors, windows or other similar objects circumstances, it is difficult or even impossible for batons to protect the function of simple demolition equipment

Taking the structure of the aforementioned CN200734676U as an example, when holding the outer tube of the telescopic baton (the patent is called "front tube") so that the end of the rear tube is aimed at the door, window or other objects for impact, under the instantaneous impact force, the unlocking mechanism will The unlocking lever (customarily called "ejector") will overcome the force of the spring of the locking mechanism and push the slider to move, so that the locking ball of the locking mechanism will be loosened, resulting in the abnormal retraction of the rear tube, and the force impact cannot be applied (specifically See paragraphs 0012 and 0014 of the specification of the patent)
