Telescopic spontoon

ActiveCN106918267AReliable lockingAvoid abnormal unlocking situationsBatonsLocking mechanismEngineering
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.

Stepless retractable spontoon

The invention relates to a stepless retractable spontoon with freely-adjustable length, belonging to the technical field of public security and riot control equipment; the stepless retractable spontoon comprises a base pipe and a retractable pole and is characterized in that: the retractable pole is sheathed in the base pipe, the rear end of the retractable pole is connected with an eccentric locking mechanism which is matched with the base pipe, and the front end of the retractable pole is connected with the end of the spontoon; a rubber-plastic compound layer is coated outside the base pipe, and anti-skidding grains are arranged on the rubber-plastic compound layer. The stepless retractable spontoon has the beneficial effects that: 1. as the eccentric locking mechanism can be locked tightly and loosed at any position, the length of the spontoon can realize stepless adjustment within a certain range, and once screwing is carried out, the spontoon is tightened, the extension is free and the usage is convenient; 2. the structure is simple, the using property is reliable, the structural intensity of the spontoon is high, impact force is heavy and the spontoon is not easy to deform; 3. the ends of the spontoon adopt tube-spring structures, the impacting force can be effectively controlled, so as to better realize the purpose of the spontoon.
