Description

(1) Technical field:

[0001] The invention relates to a folding device, in particular to a self-locking folding device. (two) background technology:

[0002] There are two types of connection methods for bicycles, tricycles, motorcycles, motorcycles and other frames and fronts: fixed and folding. Take bicycles as an example:

[0003] The folders used in conjunction with folding bicycles mainly include the following types

[0004] 1. Bolt-type folder: After the bicycle frame is closed, the bolt set on one side of the lock body needs to be inserted to fix the frame. The insertion pin used in this one-way insertion method is an equal-diameter cylinder, and the cylinder and the lock hole are in a sliding fit. The gap of the sliding fit is worn and increased with the use of the vehicle, so that the original technology of the frame bolt sleeve fit The state changes, which in turn affects the stability of the bicycle when riding, and may even cause safety problems.

[0005] 2. Ec...
