Abstract
The utility model relates to a front fork stem structure which comprises a crown body. The middle part of the crown body is provided with a front fork middle pipe fixing hole; and both sides of the front fork middle pipe fixing hole on the crown body are provided with front fork branch pipe fixing holes. The front fork stem structure is characterized in that metal stems are inserted in the front fork branch pipe fixing holes; and the metal stems are sleeved with stainless steel sleeves. The front fork stem structure has the advantages that compared with a conventional electroplated front fork stem structure, the front fork stem structure has high appearance quality, is simple to produce and manufacture, is low in production cost and cannot cause environment pollution due to electroplating in the production process.
Description
Technical field
The utility model belongs to tricycle technical field, particularly relates to a kind of vertical tube of front fork structure.
Background technology
The kind of tricycle is varied, comprise road cycling, mountain bike, Electrical Bicycle and electro-tricycle etc., along with improving constantly and development and the maturation of vehicle technology of people's environmental consciousness, Electrical Bicycle, electro-tricycle have become the main traffic instrument of people's trip, and the functional stronger bicycles such as mountain bike and road cycling are more and more subject to liking of people.
Front fork is the primary member on tricycle, and front fork comprises pipe and front fork arm in Front crown, front fork, has pipe fixed orifice in the front fork for front fork pipe is installed on Front crown, and Front fork end covers to be had for front fork front fork by all means fixed orifice is by all means installed.In conventional art, front fork arm is the metal standpipe that outside face has electrodeposited coating, and not only productive costs is high for this front fork arm, processed complex, and contaminated environment in electroplating process.
Summary of the invention
The utility model is that the vertical tube of front fork productive costs existing in solution known technology is high, production process can cause the technical matterss such as environmental pollution and provide a kind of simple in structure, processing and manufacturing is easy, productive costs is low, and production process can not cause environmental pollution, the vertical tube of front fork structure that profile quality is high.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: a kind of vertical tube of front fork structure, comprise that shoulder covers body, the middle part of described shoulder lid body has pipe fixed orifice in front fork, the both sides that are arranged in described front fork pipe fixed orifice on described shoulder lid body have front fork arm fixed orifice, it is characterized in that: in described front fork arm fixed orifice, be fitted with metal standpipe, the outer cover of described metal standpipe is equipped with corrosion-resistant steel sleeve pipe.
The utility model can also adopt following technical scheme:
The lower end of described front fork arm fixed orifice is provided with counterbore, between described counterbore and described metal standpipe, forms groove, and the upper end of described metal sleeve is inserted in described groove.
Described metal standpipe is metal standpipe.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, design a kind of novel vertical tube of front fork structure, in front fork arm fixed orifice in this shoulder lid, be fitted with metal standpipe, the outer cover of metal standpipe is equipped with corrosion-resistant steel sleeve pipe, compare tradition and electroplate vertical tube of front fork, this novel profile quality is high, the manufacturing is simple, productive costs is low, and can not cause environmental pollution because electroplating in production process.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, shoulder covers body; 1-1, front fork arm fixed orifice; 1-2, counterbore; 2, in front fork, manage; 3, metal standpipe; 4, corrosion-resistant steel sleeve pipe.
Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of vertical tube of front fork structure, comprises that shoulder cover body 1, and the middle part that shoulder cover body 1 has pipe fixed orifice in front fork, manages 2 for fixing front fork, takes on to cover the both sides that are arranged in front fork pipe fixed orifice on body 1 and have front fork arm fixed orifice 1-1.In front fork arm fixed orifice 1-1, be fitted with metal standpipe 3, the outer cover of metal standpipe 3 is equipped with corrosion-resistant steel sleeve pipe 4.Compare tradition and electroplate vertical tube of front fork, this novel profile quality is high, the manufacturing is simple, productive costs is low, and can not cause environmental pollution because electroplating in production process.
The lower end of front fork arm fixed orifice 1-1 is provided with counterbore 1-2, and the diameter of counterbore 1-2 is greater than the diameter of front fork arm fixed orifice 1-1.3 extruding of metal standpipe enter shoulder and cover in the front fork arm fixed orifice 1-1 of body 1, between counterbore 1-2 and metal standpipe 3, be formed for the groove of plug-in mounting corrosion-resistant steel sleeve pipe 4 upper ends, thereby the corrosion-resistant steel sleeve pipe 4 that makes to be sleeved on metal standpipe 3 outsides and shoulder cover body closely, perfection is connected, avoid producing gap between corrosion-resistant steel sleeve pipe and Front crown, improve overall appearance and the quality of front fork.
In the present embodiment, it is that solid aluminium matter shoulder covers body that shoulder covers body, and metal standpipe is metal standpipe.
Above-mentioned embodiment is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model: be irony housing etc. as shoulder covers body, within all dropping on protection domain of the present utility model.
