Bottom plate of clamped foaming injection type saddle and saddle matched with bottom plate

Technical Field

The utility model relates to a saddle relates to bicycle, motorcycle or electric motor car field, especially relates to a bottom plate of tight foaming injection type saddle and the saddle of cooperation bottom plate of pressing from both sides.

Background

The bicycle is a big bicycle country because most people select bicycles as the transportation tools during traveling due to the restriction of economic factors, traffic conditions and other factors, and the bicycles are favored by people due to light weight, low price and the like.

Bicycles, also known as bicycles or bicycles, are usually two-wheeled small land vehicles, which are environment-friendly vehicles powered by pedaling after people ride on the bicycle. In china, taiwan, singapore, commonly referred to as "bicycle" or "pedal cycle"; it is commonly called "bicycle" in hong Kong and Australia (although cantonese is commonly called as such); and in Japan, called "self-carriage"; the bicycle is of various types, including single-person bicycles, double-person bicycles and multi-person bicycles.

The bicycle is one of the most successful human-powered machines of the human utility model, is a complex machine consisting of a plurality of simple machines, and has higher and higher requirements on the research and development and technical speciality of bicycle products along with the development of the society.

The saddle is an essential part mounted on the bicycle seat tube to provide sitting support. However, currently, in the field of bicycles, motorcycles or electric vehicles, when the saddle adopts the existing structure, the technology of the saddle is similar to that of a common saddle, and only a PVC leather sheath is adopted to replace artificial leather. Manufacturing a bottom plate and a leather layer by an injection molding machine, and then matching with a split foaming layer with relatively low comfort level to manufacture a finished product; the floor board eraser glue is adhered to the foaming layer and then wrapped by the leather layer to form a whole; the defects of the prior art are relatively obvious, more foaming waste materials are generated in the manufacturing process, white pollution can be caused, the working procedures are complicated, the labor cost is high, the manufacturing time is long, and the environment is not protected due to the use of glue and a release agent.

In order to solve the above-mentioned drawbacks of the prior art, a new saddle structure needs to be designed.

The conventional foaming injection type saddle comprises a bottom plate and a leather sleeve which is adaptive to the shape of the bottom plate, wherein a cavity for accommodating a foaming layer is formed between the leather sleeve and the bottom plate; in order to ensure that the foaming does not overflow from the edges of the bottom plate and the leather sheath of the cavity in the foaming process, the material of the leather sheath, especially the material of the matched part of the edges of the leather sheath and the bottom plate, is harder, so that the corresponding matched gap can be ensured to ensure that the foaming does not overflow, but the whole softness of the saddle is poor due to the technical material, and the comfort level is lacked.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide the bottom plate of the foaming injection type saddle that presss from both sides tightly and cooperate the saddle of bottom plate.

The utility model discloses a realize through following technical scheme:

a bottom plate of a clamped foaming injection type saddle is characterized in that a sealing edge extending downwards is arranged on the periphery of the edge of the bottom plate, an accommodating edge is arranged on the periphery of the edge of the bottom plate on the inner side of the sealing edge, and the sealing edge, the accommodating edge and the bottom plate jointly form an accommodating groove with a downward opening;

the circumference of the containing edge is provided with a clamping part extending towards the inner side.

And an injection through hole for injecting foaming is formed in the middle of the bottom plate.

The injection through hole is provided with a plug buckled on the injection through hole.

A saddle matched with a bottom plate comprises a leather sleeve buckled with the edge of the bottom plate, and a cavity for accommodating a foaming layer is formed between the leather sleeve and the bottom plate;

the foaming layer is formed by pouring, and the whole cavity is filled with the foaming to form the saddle with rebound resilience and comfort;

a horizontal flange corresponding to the sealed edge is arranged on the periphery of the edge of the leather sheath, the inner side of the horizontal flange extends vertically upwards to form an inserting edge, and the inserting edge is inserted into the accommodating groove;

the clamping portion clamps the insert edge to the sealing edge.

The utility model has the advantages that:

because the circumference on holding limit is processed the clamping part that extends to the inboard, and the edge circumference of leather sheath is equipped with the horizontal flange that corresponds with the banding, the inboard perpendicular upwards extension of horizontal flange forms the edge of inserting, insert in the limit inserts the storage tank, through blockking of banding lower extreme profile, effectually will foam the chamber and close between bottom plate upside and banding lower extreme profile, also effectually prevent to foam under the condition that uses soft leather sheath and spill over.
