Detailed Description
The present utility model will be described in further detail below with reference to the drawings and preferred embodiments, so that those skilled in the art can better understand the technical solutions of the present utility model. All other embodiments, based on the embodiments of the utility model, which would be apparent to one of ordinary skill in the art without making any inventive effort are intended to be within the scope of the utility model.
In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the utility model.
Furthermore, it should be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "configured," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be directly connected, can be indirectly connected through an intermediate medium, and can also be communicated with the inside of two elements. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.
Embodiment 1 As shown in the figure, the utility model comprises two side pipes 4 oppositely arranged, a vertical pipe 2 connected to the front side between the two side pipes 4, a seat pipe connected to the middle part between the two side pipes 4 and a front fork sleeve 1 fixedly connected to the upper end of the vertical pipe 2, wherein the middle section of the front side of the side pipe 4 is connected with the middle part of the vertical pipe 2, and a space is reserved between the front end of the side pipe 4 and the front fork sleeve 1 and between the front end of the side pipe 4 and the vertical pipe 2. In the embodiment, the end part of the side pipe 4 and the vertical pipe 2 are designed to be of an open structure, the working procedures of welding, screw fixing and the like are not needed, the manufacturing process of the connecting structure of the side pipe 4 is effectively optimized, the processing efficiency is improved, and the labor and time of workers are saved, and the side pipe is put into production more efficiently.
