Description
Technical field
The utility model relates to a kind of child's bicycle front fork structure, be specifically related to a kind of front fork adjusted up and down by handlebar and Front crown tightening screw locking reach to handlebar height regulate adjustable child's bicycle front fork structure.
Background technology
Child's bicycle front fork is all the rare Double-shoulder type of plain type on the market at present, and front fork and handlebar are all that Split type structure is made, and above product all also exists following problem in the fabrication process with on making finished product:
1, front fork size is all fixed type, cannot regulate, and all needs the height by head tube and vertical tube of front fork length adjustment handlebar, and regulates height dimension limited.
2, front fork and handlebar are all Split type structure, and handlebar hangs tight locked by heronsbill or skewback.
Utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of front fork to be adjusted up and down by handlebar and the locking of Front crown tightening screw reaches the adjustable child's bicycle front fork structure regulated handlebar height.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of adjustable child's bicycle front fork structure, described adjustable child's bicycle front fork structure comprises handlebar, shoulder lid, fork leg, latching device, handlebar comprises a transverse tube held when cycling and two vertical tubes parallel to each other, the internal diameter of fork leg is greater than the external diameter of vertical tube, the lower end of two vertical tubes injects two fork legs respectively, shoulder lid comprises shoulder lid body part, also comprise the vertical tube standpipe inlet inserted and the head tube insert port be connected with the head tube of child's bicycle by shoulder lid, shoulder lid comprises upper and lower two, shoulder lid above and two vertical tubes are fixed, shoulder lid below and two fork legs are fixed, shoulder lid above and vertical tube adopt latching device to be fixed together, shoulder lid below and fork leg adopt latching device detouchable to be fixed together.In preferred embodiment of the present utility model, described latching device is tightening screw.
In preferred embodiment of the present utility model, described transverse tube and two vertical tube welding parallel to each other, become as a whole.
Positive progressive effect of the present utility model is: adjustable child's bicycle front fork structure that the utility model provides has the following advantages: the utility model eliminates handle riser structure of the prior art, makes the transverse tube held when cycling and two vertical tubes parallel to each other be directly integral type by argon arc welding welding manner; Reduce assembling link, make handlebar regulate more simple and fast; Fork leg is adjusted up and down by handlebar and the locking of Front crown tightening screw reaches the adjustment of handlebar height.Front crown preposition countersunk head formula 4 tightening screws front fork whole structure aobvious simply and not lose attractive in appearance.

Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation when handlebar is placed on lower position in the utility model, and Fig. 2 is structural representation when handlebar is placed on higher position in the utility model.Process from Fig. 1 to Fig. 2 only needs following steps: the first step unclamps tightening screw 4 in Fig. 1, second step requires suitably to draw high handlebar 1 height in Fig. 1 according to vehicle frame and bicyclist's height, and the tightening screw 4 that the 3rd step is locked in Fig. 2 completes adjustment.
Fig. 3 is the left view of Fig. 2, as shown in Figure 3, cancels handle riser structure common at present, and by argon arc welding welding manner, transverse tube 101 and two vertical tubes 102 parallel to each other being welded is directly integral type.In the utility model, transverse tube 101 and vertical tube 102 are directly integral type, reduce assembling link, make handlebar regulate more simple and fast.
Here is specific embodiment, the utility model comprises handlebar 1, shoulder lid 2, fork leg 3, latching device, handlebar 1 comprises a transverse tube held when cycling 101 and two vertical tubes 102 parallel to each other, the internal diameter of fork leg 3 is greater than the external diameter of vertical tube 102, when mounted, the lower end of two vertical tubes 102 injects two fork legs 3 respectively.
Fig. 4 is the front view of shoulder lid.Fig. 5 is the birds-eye view of shoulder lid.Shoulder lid 2 comprises shoulder lid body part 201, also comprise vertical tube 102 standpipe inlet 202 inserted and the head tube insert port 203 be connected with the head tube 5 of child's bicycle by shoulder lid 2, shoulder lid 2 comprises upper and lower two, shoulder lid 2 above and two vertical tubes 102 are fixed, shoulder lid 2 below and two fork legs 3 are fixed, shoulder lid 2 above adopts latching device to fix with vertical tube 102, and shoulder lid 2 below and fork leg 3 also adopt latching device (what adopt in the utility model is tightening screw 4) to fix.
Head tube 5 in the present embodiment shown in Fig. 1-3 plays front fork and his connection function of vehicle frame portion.
The utility model eliminates handle riser structure of the prior art, makes the transverse tube held when cycling and two vertical tubes parallel to each other be directly integral type by argon arc welding welding manner; Reduce assembling link, make handlebar regulate more simple and fast; Front fork is adjusted up and down by handlebar and the locking of Front crown tightening screw reaches the adjustment of handlebar height.Front crown preposition countersunk head formula 4 tightening screws front fork whole structure aobvious simply and not lose attractive in appearance.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
