The technical solution of the utility model is:
There is provided a kind of easy-to-dismount bicycle rack, the vehicle frame includes head tube, upper tube, standpipe, five logical, down tube, flat
Fork and seat stay, described five it is logical upper standpipe, down tube and chain stay are provided with by welding, be provided on the standpipe by welding
Seat stay and upper tube, the upper tube and the down tube are fixedly connected by welding in head tube, the chain stay and described
Fixation is bolted in seat stay, is provided with dismountable support in the standpipe, the upper tube and the seat stay
Bar, the support rod are bolted to connection in the middle position of standpipe, upper tube and seat stay, and support rod is provided on both ends
Boss, support rod can be replaced using damper, be arranged in standpipe, upper tube and seat stay fluted.
Further, the vehicle frame is fabricated using magnesium alloy, carbon fiber or aluminium alloy.
Further, not generally applicable between support rod described in three.
Further, the boss selects one kind of T-type, dove-tail form or triangular form.
Further, the groove selects one kind of T-type, dove-tail form or triangular form.
Further, match between the boss and the groove.
Further, the installation number of the damper is no more than 2.
The utility model has the advantages and positive effects of:
Due to the adoption of the above technical scheme, Vehicle Frame Design is reasonable, and overall structure and existing bicycle rack do not have difference, is applicable in
In various adult bicycles, support rod can be substituted for damper, and support rod can allow user according to riding at that time at three
Road selection different location is replaced, and suitable for the use of any road, while support rod is connected by screw bolts so that connecting knot
Structure is stablized, and is not both convenient to use removing and installing for person, also can protect car body.

Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the utility model is a kind of easy-to-dismount bicycle rack.
Embodiment
A kind of easy-to-dismount bicycle rack is provided, the vehicle frame includes head tube 1, upper tube 2, standpipe 3, five logical 4, down tube
5, chain stay 6 and seat stay 7 are provided with standpipe 3, down tube 5 and chain stay 6 by welding on described five logical 4, lead on the standpipe 3
It crosses welding and is provided with seat stay 7 and upper tube 2, the upper tube 2 and the down tube 5 are fixedly connected by welding in head tube 1, institute
The chain stay 6 and the seat stay 7 stated are bolted fixation, in the standpipe 3, the upper tube 2 and the seat stay 7
It is provided with dismountable support rod 8, the support rod 8 is bolted to connection in standpipe 3, upper tube 2 and seat stay 7
Between position, boss is provided on 8 both ends of support rod, support rod 8 can be replaced using damper 9, standpipe 3, upper tube 2 and vertical
It is arranged on fork 7 fluted.
Wherein, the vehicle frame is fabricated using magnesium alloy, carbon fiber or aluminium alloy.Selected metal manufacture from
Driving frame has intensity height, quality small, anticorrosive.
Wherein, not generally applicable between support rod 8 described in three.Of different sizes, the support of standpipe 3, upper tube 2 and seat stay 7
Bar 8 will lead to vehicle frame overall deformation in the case where being fitted without correct situation.
Wherein, the boss selects one kind of T-type, dove-tail form or triangular form.Selecting T-type, dove-tail form or triangular form is
In order to limit the freedom degree of support rod 8, in the case where the loosening that bolt occurs, only one direction of motion of support rod 8 is avoided
There is a situation where bolts to be detached from.
Wherein, the groove selects one kind of T-type, dove-tail form or triangular form.The surface of T-type, dove-tail form or triangular form
Product is all bigger than the surface area of square, increases forced area, disperses power suffered by tie point.
Wherein, match between the boss and the groove.Boss and groove in absence of such a match may be used
With normal use, but in the event of a match, the contact area of boss and groove can be increased, improve vehicle frame itself is strong
Degree.
Wherein, the installation number of the damper 9 is no more than 2.In view of the structure of vehicle frame entirety, in order to guarantee vehicle
The stabilization of frame and the safety of user control the installation number of damper 9 within two.
The application method of this example:
Whether intact first check for each components, especially boss and groove, checking can be by vehicle frame after no corrupted
It assembles, support rod 8 need to only be installed in correct position, then junction is fixed with bolt, after confirming without loosening
Vehicle frame is just installed, and assembled vehicle frame is as shown in Figure 1.
As shown in Fig. 2, there are three support rods 8 altogether for entire vehicle frame, each support rod 8 can be by the damper of same size
9 are replaced, but cannot be reached by replacing quantity by three, and user, which needs to ride in highway, does not need replacement support rod 8,
Because of highway relatively flat, damper 9 can accelerate the physical consumption of user, ride if it is in hill path, most importantly
Support rod 8 on standpipe 3 is substituted for damper 9, standpipe 3 is most important place in vehicle frame, secondly, user can basis
Road conditions and hobby require to remove the support rod of replacement upper tube 2 or the support rod 8 of seat stay 7, and user also can choose and not replace.
Stress condition of the upper tube 2 in vehicle frame is only second to standpipe 3, and upper tube 2 and standpipe 3 bear the overwhelming majority from outer
The power that upper tube 2 and standpipe 3 are born after this support rod 8 at two is all substituted for damper 9, can be offset one by the power on boundary
Part mitigates the body burden of user, if standpipe 3 and the support rod of seat stay 78 are substituted for damper 9 simultaneously, can drop
Low user is at the center of ride, and center back deviates, and will not overturn on the road to downward driving.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
