Description

Technical Field

[0001] The utility model relates to the field of auxiliary mechanisms for vehicle assembly, in particular to a convenient buckle structure. Background Art

[0002] A tricycle is a means of transport modified from a bicycle. It can carry people or goods. It became very popular after the 1930s and gradually replaced the position of rickshaws. A tricycle is a combination of a rickshaw and a bicycle. Tricycles can be divided into human-powered tricycles, electric tricycles, children's tricycles and battery tricycles.

[0014] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0015] Embodiment 1:

[0016] The convenient buckle structure proposed in this embodiment includes four components: a carriage body, a positioning frame 3, a support frame 4 and a locking rod 5. The carriage body has a predetermined operating size and bearing capacity, and can perform corresponding bearing and positioning operations. The positioning frame 3 is placed on the operating surface of the carriage body, has a predetermined operating length and supporting force, and is provided with corresponding through holes, and can perform corresponding bearing and limiting operations. The support frame 4 is placed on the operating surface of the carriage body, has a predetermined operating size, and the operating position corresponds to the operating position of the positioning frame 3, and is provided with corresponding open grooves, and can perform corresponding supporting and limiting operations. The locking rod 5 passes through the through hole provided by the positioning frame 3 and the open groove provided by the support frame 4, and has a predetermined bending arc, and can perform corresponding locking and limiting operations. In a further preferred embodiment, the locking rod 5 is L-shaped. The locking rod 5 movably passes through the through hole provided by the positioning frame 3, and can perform a predetermined range of movable adjustment operations in the through hole provided by the positioning frame 3, that is, the operating direction can be flexibly adjusted in the left and right directions in the through hole provided by the positioning frame 3. The carriage body includes two components, a rear door 2 and a side door 1, and the side door 1 is multiple; the positioning frame 3 is placed on the working surface of the side door 1, and the supporting frame 4 is placed on the working surface of the rear door 2, and the positioning frame 3 and the supporting frame 4 are multiple. In a further preferred embodiment, there are two side doors 1, which are placed on the left and right sides of the rear door 2 respectively.

[0017] Embodiment 2:

[0018] On the basis of the first embodiment, a limiting nut 6 is provided at one end of the locking rod 5 away from the supporting bracket 4, and the overall operating size of the limiting nut 6 is larger than the operating size of the through hole provided on the positioning bracket 3. In the later operation process, the corresponding limiting and fixing operation can be performed by the limiting nut 6. The open groove provided on the supporting bracket 4 is U-shaped, and the operating position of the U-shaped open groove provided on the supporting bracket 4 is at the same height as the operating position of the through hole provided on the positioning bracket 3. Multiple positioning brackets 3 are respectively placed on the working surface of multiple side doors 1, and multiple supporting brackets 4 are symmetrically distributed on the working surface of the rear door 2. In a further preferred embodiment, there are two positioning brackets 3, and they are respectively distributed at one end of the two side doors 1 close to the rear door 2.

[0019] Based on the above embodiment, the working process of the utility model is as follows: first, in the locked state, the locking rod 5 passes through the through hole provided by the positioning frame 3 and the open groove provided by the support frame 4, and the bent end faces downward in the working direction, so that the rear door 2 and the side door 1 of the carriage body are fixedly locked under the cooperation of the positioning frame 3 and the support frame 4, that is, the rear door 2 and the side door 1 are in a fixed state and cannot be adjusted. When it is necessary to open the side door 1 of the carriage body, it is only necessary to rotate the bent end of the locking rod 5 upward in the working direction so that the bent end of the locking rod 5 is level with the open end of the open groove provided by the support frame 4, and then push the locking rod 5 in the horizontal direction toward the direction close to the positioning frame 3, so that the bent end of the locking rod 5 is separated from the support frame 4, and then the support frame 4 can be completely separated from the positioning frame 3, and then the side door 1 of the carriage body can be opened. When the side door 1 and the rear door 2 of the vehicle body need to be fixed again, the above steps only need to be reversed.

[0020] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
