Problems solved by technology

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 will affect the stability of the bicycle when riding, and even cause safety problems
[0005] 2. Eccentric pressure folder: During the folding process of the bicycle frame, if the eccentric angle of the handle and the pressure thread are not adjusted properly, the frame will loosen the structure of the lock body due to the vibration stress during the riding process, resulting in a certain degree of security risks
[0006] 3. Threaded connection folder: The folding frame is connected by thread fit. This folding connection method is very troublesome to assemble when the threads are docked with each other, and the action is slow. The most fatal thing is the damage to the frame thread, which directly makes the frame Unable to install utility

Embodiment Construction

[0025] The structure of the self-locking folding device of the present invention includes a directly hinged folding main body 1 and a folding auxiliary body 2. In the actual product, the folding main body 1 is called the device shell, and the folding auxiliary body 2 is called the revolving cover, as shown in Figure 1 , Figure 2, Figure 3, Figure 4, Figure 5 shown.

[0026] The folding main body 1 is a rectangular plate, and the folding auxiliary body 2 is a rectangular shell that is covered with the folding main body 1. It is in closed state when folded and overlapped, as shown in Figure 1 and Figure 3, and it is in open state when the folding auxiliary body 2 and folding main body 1 are rotated, and they are separated, as shown in Figure 2, Figure 4 and Figure 5.

[0027] The front ends of the folding main body 1 and the folding auxiliary body 2 are respectively fixed with a semi-conical pin 3 and its coaxial semi-circular hole, and the taper of the semi-conical pin 3 decrea...

Abstract

The self-locking folder includes one main folding body and one subsidiary folding body hinged mutually, as well as two semi-conic bolts with semi-circular hole separately in the main folding body and the subsidiary folding body and capable of being closed to form one conic bolt with one circular hole, one guide rod capable of matching the circular hole, one conic sleeve on the guide rod capable of clamping the conic bolt under the action of an elastic mechanism, and one clutch mechanism on the main folding body for separating the conic sleeve from the conic bolt. The main folding body and the subsidiary folding body after being closed are self-locked safely and smoothly. The self-locking folder may be folded fast easily, and is suitable for use in bicycle, tricycle, motorcycle, electric bicycle, etc.

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...
