Description
Technical Field
The invention belongs to the technical field of police antiriot equipment, and particularly relates to a drum-butterfly and pipe body locking groove matching structure of a telescopic baton.
Background
The telescopic spontoon is one of police equipment worn by public security policemen in China, particularly public security policemen and armed policemen on duty, and is also called a 'baton' or a 'telescopic roller' and the like because the telescopic spontoon is of a telescopic structure and is mostly used in a throwing state. The number of segments of a telescopic baton is usually three, and the telescopic baton is composed of an outer tube, a middle tube and a rear tube (also called as "front tube, middle tube and rear tube"), for which reference may be made to patents such as CN104457414A (telescopic baton capable of improving assembly convenience and stability), CN105865259A (positioning control mechanism of telescopic baton), CN101598521A (a stepless telescopic baton), CN200734676U (telescopic baton) and US20130150167 (telescopic baton), etc. See in particular the following two chinese patents which eliminate the disadvantages of the aforementioned chinese and foreign patents: one is the "telescopic baton" recommended by CN 106918267B; secondly, provide "telescopic baton of institutional advancement" for CN 106931830B.
Common features not limited to the patents listed above are: when the pipe body is thrown out and in a working state, such as in the process of impacting vehicle glass, building doors and windows or similar objects, the middle pipe body is limited at the throwing-out position in the outer pipe body by the middle pipe body drum butterfly of the structural system of the middle pipe body supporting and limiting mechanism, and the rear pipe body is limited at the throwing-out position in the middle pipe body by the rear pipe body drum butterfly of the structural system of the rear pipe body supporting and limiting mechanism, so that the effects of preventing the middle pipe body from being abnormally retracted into the outer pipe body and preventing the rear pipe body from being abnormally retracted into the middle pipe body are achieved. More specifically, the middle tube body is supported and limited by the matching of the middle tube body butterflies and the middle tube body butterflies groove formed in the cavity wall of the outer tube body cavity of the outer tube body, namely, the middle tube body butterflies extend into the middle tube body butterflies groove formed in the cavity wall of the outer tube body cavity, so that the middle tube body butterflies support the middle tube body and cannot retract into the outer tube body cavity unless the middle tube body butterflies exit from the middle tube body butterflies groove under the action of the unlocking rod of the unlocking mechanism. Whether the rear pipe body drum butterfly is matched with the rear pipe body drum butterfly groove formed in the cavity wall of the middle pipe body cavity of the middle pipe body is the same as that of the middle pipe body drum butterfly or not, and therefore repeated description is omitted.
Taking the above-mentioned middle tube body butterfly as an example (the same example is applied to the rear tube body butterfly), it can be seen from the reading of the above-mentioned CN106918767B and CN106931830B that, theoretically, as long as the unlocking mechanism does not produce the unlocking action on the middle tube body butterfly, the middle tube body butterfly will always be in the state of being matched with the above-mentioned middle tube body butterfly groove and will not exit from the middle tube body butterfly groove, and the middle tube body butterfly will be in the good supporting state of the middle tube body and will not be abnormally retracted into the outer tube cavity of the outer tube body. However, in the actual use process, when the impact head of the rear tube body of the telescopic baton is subjected to strong impact force, the middle tube body drum butterfly can have the tendency of moving towards the center direction of the middle tube body cavity of the middle tube body after exiting from the middle tube body drum butterfly groove, a sliding surface is formed between the middle tube body drum butterfly and the middle tube body drum butterfly groove, and along the sliding surface, the middle tube body drum butterfly easily slides out of the middle tube body drum butterfly groove to lose the locking effect, so that the middle tube body retracts into the outer tube body cavity of the outer tube body, and the due effect of the telescopic baton is influenced. The rear tube body is the same as the first tube body and is not described again. Therefore, the problem of how to prevent the middle tube body butterfly from abnormally withdrawing from the middle tube body butterfly groove is always troubled in the industry, and reference technical suggestions are not found in the published Chinese and foreign patent documents, and the technical scheme to be described below is generated under the background.
