Abstract

The utility model relates to a novel folder which is composed of a main vehicle frame, an auxiliary vehicle frame, a folding convex block, a notch, a folding concave block and a connecting shaft. The novel folder further comprises a bearing frame, a safety block and a connecting rod. The folding concave block is connected with a bracket into one body, the bracket is flexibly connected with the connecting rod by a pin, and the connecting rod is also flexibly connected with a handle by the pin. The novel folder is characterized in that: a convex block is also arranged on the handle and is matched with the notch on the folding convex block, and the connecting rod on the handle is connected with the bearing frame; when the folding concave block and the folding convex block are clamped, under the function of a spring, the safety block of the handle is tightly locked by a safety hook on the handle and the safety block on the bracket or the safety hook on the connecting rod; therefore, the folder is tightly clamped and cannot be separated, and the handle can be opened or the folder can be separated due to any impact or foreign matters. The novel folder is fairly simple and the utilization is fairly convenient.

Description

A new type of folder

technical field

The utility model relates to a novel folder.

Background technique

The 02227767.6 folder disclosed in Chinese patent, this kind of folding is provided with a driving lever on the rotating shaft, the lower folding body is provided with a driving lever opening, and the upper folding body is provided with a long opening, so that the handle is provided with an eccentric locking mechanism. On the lever, once the lever is touched or loosened, the folding part of the bicycle will be separated automatically. In order to overcome the above shortcomings, it is provided with a locking hole on the side of the upper folding body, and a locking hole is provided at one end of the rotating shaft to match the locking hole. The locking pin is provided with a spring on the other side of the rotating shaft, and the locking lock on the rotating shaft naturally enters into the locking hole of the upper folder through the pressure of the spring, but when folding, when the handle is opened, the handle is rotated, and the lever is connected There is an integrated shaft and the moving shaft makes the upper lock pin and the locking hole return to separate the folder. This structure is not only complicated in structure, but also very inconvenient to use.

Contents of the invention

The utility model provides a folder with a safety device, which consists of a main frame, an auxiliary frame, a folding bump, a folding concave block, a connecting shaft, a gap, a support frame, a bracket hole, a handle, a handle bump, a handle hole, It consists of connecting rod, connecting rod hole, connecting rod pin, safety block, safety hook, button and spring. The main frame is fixedly connected with the folding bump, the sub-frame is fixedly connected with the folding concave block, and the folding bump and the folding concave block are movably connected through the connecting shaft. The folder is automatically separated to cause danger, and a safety device is provided on the handle. Only when the safety device button is pushed, the safety hook connected to the button leaves the safety block, and the folding device can be realized, which overcomes the defects in the prior art. , the utility model has a notch at one end of the folding bump to match the bump on the handle, one end of the folding concave block is fixedly connected with the support frame, the connecting rod is movably connected with the support frame through the connecting rod pin, and the other part of the connecting rod One end and the handle pass through the connecting rod hole, and the handle hole is movably connected with a pin. There is also a safety block on the support frame (attachment 1), and the safety block can also be set on the connecting rod (attachment 2). There are springs around the hook, and the safety hook is integrated with the button. When in use, push the button safety hook to leave the safety block, pull the handle, and the protrusion on the handle leaves the gap on the folding protrusion, and it can be opened when it is folded. At the same time, the folder combines the folding concave block with the folding block through the movable connection of the shaft, and at the same time puts the protrusion on the handle into the gap on the folding protrusion, and then pushes the handle to the direction of the sub-frame. The connection relationship is that the folding concave block is closely connected with the folding convex block. When it is pushed forward, the safety hook automatically enters the matching safety block under the condition of the self-returning function of the spring. The utility model is not only simple in structure, but also easy to use Very convenient and easy to manufacture.

Detailed ways

The main frame 1 is fixedly connected with the folding bump 2, the sub-frame 5 is fixedly connected with the folding concave block 4, the folding concave block 2 and the folding bump 4 are movably connected through the connecting shaft 3, and one end of the folding bump 2 is provided with a notch 6 and be provided with bump 7 to match on the handle 15, be provided with support frame 8 to be fixedly connected on the folding concave block 4, also have hole 9 on the support frame 8, have hole 14 at the two ends of connecting rod 19, connecting rod 19 One end is movably connected with support 8 by pin 16, and support frame 8 is also provided with safety block 18 (accompanying drawing one), and safety block 18 also can be provided with on the connecting rod 19 (accompanying drawing two), the other end of connecting rod 19 and handle 15 is movably connected by pin 20, and the handle 15 of the present utility model is provided with a safety hook 17, and matches with the safety block 18 on the support 8, or matches with the safety block 18 on the connecting rod 19, and the safety hook 17 and the handle 15 pass through the pin 12 Movably connected, the safety hook 17 is surrounded by a spring 13, and the safety hook handle 10 at one end of the safety hook 17 is fixedly connected with the button 11 as a whole. When the hook 17 leaves the safety block 18 and pulls the handle 15, when the connecting rod 19 connected with the handle 15 goes out at the same time, the handle 15 rotates around the supporting frame 8 pin 16 as the center, and the protrusion 7 on the handle 15 also leaves the folding protrusion. The notch 6 on the block 2 can be opened by the folder, and the bicycle can be folded. When riding, the folding concave block 4 and the folding convex block 2 are combined under the action of the connecting shaft 3, and the handle 15 Protrusion and folding 2 in the notch 6, then the handle 15 is pushed toward the vehicle frame 5 direction, the safety hook 17 moves closer to the safety block 18 and enters in the safety block 18, and is automatically locked. The structure of the invention is very simple, and the use is very convenient, and safe and reliable.
