Description

Technical Field

[0001] The utility model relates to the technical field of scooters, in particular to a head tube folding scooter. Background Technique

[0002] The tricycle is a means of transportation transformed from a bicycle, which can carry people or goods. It was very popular after the 1930s and gradually replaced the rickshaw. The tricycle is a combination of a rickshaw and a bicycle. Tricycles can be divided into manual tricycles, electric tricycles, children's tricycles, battery tricycles, etc. Electric tricycles: They have the characteristics of beautiful appearance, energy saving and labor saving, good climbing performance, flexible steering, economic practicality, reliable quality and environmental protection.

[0003] When the current tricycle is in use, since the position of the handlebar and the frame body are integrated with each other, the head tube cannot form a flipping and folding effect. When it is stored, due to the high support of the handlebar, it also occupies a relatively large space during storage, resulting in inconvenience in storage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a head tube folding scooter to solve the problem that when the current tricycle is in use, since the position of the handlebar and the frame body are integrated with each other, the head tube cannot form a flipping and folding effect. When it is stored, due to the high support of the handlebar, it also occupies a relatively large space during storage, resulting in inconvenience in storage as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A head tube folding scooter, including a main frame body, fixed blocks are symmetrically welded on the top surface of the main frame body, a flipping rod body is inserted between the sides of the fixed blocks, flipping buckle rods are symmetrically butted on the outer side of the flipping rod body, a main head tube body is fixedly welded at the top end of the flipping rod body, a hand-held rod body is horizontally fixedly connected between the sides of the flipping buckle rods, an outer packaging sleeve is fixedly sleeved on the outer side of the flipping rod body, connecting springs are symmetrically connected to the outer side of the outer packaging sleeve, limiting shaft rods are symmetrically welded on the side of the flipping rod body, a flipping shaft rod is horizontally fixedly inserted on the side of the flipping rod body, a buckling hook groove is opened at one end of the flipping buckle rod far away from the hand-held rod body, and a main shaft rod is horizontally fixedly connected between the sides of the fixed blocks.

[0007] As a preferred implementation mode of the utility model: The main frame body is arranged in a three-wheel structure, the number of fixed blocks is two, and the two fixed blocks are arranged parallel and symmetrically to each other. Both fixed blocks are symmetrically and vertically fixedly arranged at the top end of the opening at one end of the center line of the main frame body.

[0008] As a preferred embodiment of the present utility model: the flipping rod body is provided with a hollowed-out and lightweight structure, and the bottom end of the flipping rod body is inserted between the side edges of two fixed clamping blocks. The number of flipping buckle rods is two, and the two flipping buckle rods are arranged in parallel with each other. The two flipping buckle rods are symmetrically arranged at the top positions near the side edges of the flipping rod body close to the fixed clamping blocks, and the two flipping buckle rods are arranged in an inclined shape.

[0009] As a preferred embodiment of the present utility model: the main head tube body is arranged in the structure of a faucet handle. The two ends of the hand-held rod body are fixedly connected by bolts at the side positions near the top between the two flipping buckle rods. The number of connecting springs is two, and one end of each of the two connecting springs is sleeved on the outer rod position of the outer packaging sleeve, and the other end is fixedly sleeved on the side clamping holes of the flipping buckle rods.

[0010] As a preferred embodiment of the present utility model: one end of the limiting shaft rod is horizontally inserted into the side groove of the flipping buckle rod, and the two ends of the flipping shaft rod are horizontally inserted into the side through holes of the flipping buckle rod. The buckling hook groove is opened in a hook shape, and the buckling hook groove is buckled on the outer side of the shaft rod between the fixed clamping blocks.

[0011] As a preferred embodiment of the present utility model: the two ends of the main shaft rod are fixedly connected to the side through holes of the fixed clamping blocks, and the main shaft rod is horizontally inserted through the through hole near the bottom end of the flipping rod body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] After a person holds the hand-held rod body, by pressing the hand-held rod body downward, the limiting shaft rod moves along the side groove of the flipping buckle rod. Under the connection of the flipping shaft rod, the flipping buckle rod makes a flipping movement on the outer side of the outer packaging sleeve, so that the buckling hook groove at the bottom disengages from the shaft rod between the fixed clamping blocks, forming the release of the support limitation of the flipping rod body. Then, without the support and limit connection of the flipping buckle rod, the main head tube body can be flipped towards the main frame body. The bottom end of the flipping rod body fixedly connected to each other forms a flipping movement under the connection of the main shaft rod, and the main head tube body can be flipped and folded and buckled on the top surface of the main frame body. When the tricycle is in use, after the main head tube body is flipped to a vertical state, under the support of the connecting spring, the buckling hook groove at the bottom of the flipping buckle rod is tightly buckled on the outer side of the shaft between the fixed clamping blocks, and after the flipping buckle rod is connected, it forms a limit and fixation effect on the flipping rod body. The adoption of the snap-type flipping and folding structure makes the folding operation more convenient and simple. At the same time, when set as a folded structure, the tricycle does not occupy a large space during storage. Description of the Drawings

The two fixed blocks 2 are symmetrically and vertically fixed at the top position of the opening at one end of the midline of the main frame body 1. A flipping rod body 3 is inserted between the sides of the fixed blocks 2. Flipping buckle rods 4 are symmetrically butted on the outer side of the flipping rod body 3. The flipping rod body 3 is set with a hollow and lightweight structure, and the bottom end of the flipping rod body 3 is inserted between the sides of the two fixed blocks 2. The number of the flipping buckle rods 4 is two, and the two flipping buckle rods 4 are arranged parallel to each other. The two flipping buckle rods 4 are symmetrically arranged at the top positions near the fixed blocks 2 on both sides of the flipping rod body 3. The two flipping buckle rods 4 are arranged in an inclined shape. A main head tube body 5 is fixedly welded to the top end of the flipping rod body 3. A hand holding rod body 6 is horizontally fixedly connected between the sides of the flipping buckle rods 4. An outer packaging sleeve 7 is fixedly sleeved on the outer side of the flipping rod body 3. Connecting springs 8 are symmetrically connected to the outer side of the outer packaging sleeve 7. The main head tube body 5 is arranged in a structure of a faucet handle. The two ends of the hand holding rod body 6 are fixedly connected by bolts at the positions near the top between the sides of the two flipping buckle rods 4. The number of the connecting springs 8 is two.
