Abstract

The invention discloses a double-locking connecting device with a verification function. The double-locking connecting device comprises a male plug provided with a boss and a connecting sleeve (1), acavity is arranged in the connecting sleeve (1), one side of the connecting sleeve (1) is provided with a jack (11) communicated with the cavity, the other side of the connecting sleeve (1) is provided with a mounting hole (12) communicated with the cavity, two receding holes (13) communicated with the cavity are further symmetrically formed in the connecting sleeve (1), and bumping posts (14) arearranged between the mounting hole (12) and the receding holes (13) in the corresponding ends; and a locking block (2) and a positioning block (3) which extend into the cavity from the mounting hole(12) and are superposed up and down are arranged in the cavity. The positioning block and the locking block are arranged in the connecting sleeve to double lock the male plug, the assembly in-place condition of the male plug can be rapidly checked, the structure is simple and compact, and operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a double-lock connection device with a verification function. Background technique [0002] At present, the quick connecting device widely used in automobile (fuel) pipeline system mainly adopts a single locking mechanism. Generally, the single locking mechanism connection device is unlocked by external force (vibration, flying stones, etc.) during the working process, resulting in a high risk of pipeline system leakage. Improving the single locking mechanism to a double locking mechanism can solve the above problems very well. In the case that any of the above locking mechanisms is unlocked and fails, the other locking mechanism can still lock the male joint that is assembled with it. in the connecting device. Although there are multiple double locking mechanism connection devices that have been applied to automobile (fuel) pipeline systems. However, there ar...
