Description
Technical field
The utility model relates to bicycle art, especially relates to a kind of bicycle back claw structure.
Background technology
The raw MAT'L of existing back claw is 6061 aluminum alloys.Main alloy element in 6061 aluminum alloys is magnesium and silicon, has medium tenacity, good resistance to corrosion, weldability, and oxidation effectiveness is better, and 6061 is a kind of cold treatment aluminium forging products, is applicable to require high application to resistance to corrosion, oxidisability.Workability is good, and interface characteristic is excellent, easy coating, and processability is good.
Had by 6061 aluminum alloy forged back claws and met the daily enough hardness used of riding, but some special vehicles, such as, when field vehicle, mountain bike etc. need the vehicle of higher bearing strength, only cannot ensure that hooking pawl can not be out of shape because of the excessive transverse direction produced when riding and longitudinal force completely by aluminum alloy back claw itself, and then cause dangerous generation.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of bicycle back claw structure.
The utility model adopts following technical scheme:
A kind of bicycle back claw structure, is characterized in that: comprise hook, reinforced sheet and screw; Described hook adopts aluminum alloy materials to make, and hook is provided with Access Division A, fixed orifice A and groove; Described reinforced sheet adopts high-carbon steel material to make, and reinforced sheet is provided with Access Division B and fixed orifice B; Reinforced sheet is screwed with hook and is connected.
As preferred technical scheme, Access Division A is U-shaped.
As preferred technical scheme, Access Division B is U-shaped.
As preferred technical scheme, fixed orifice B is tapped bore.
Compared with prior art, the beneficial effect of a kind of bicycle back claw of the utility model structure is: structure is simple, and it is convenient to assemble, and arranges reinforced sheet at hook pawl, do not strengthening under the condition hooking pawl thickness, guarantees back claw
intensitywith
rigidity, thus effectively can avoid the distortion hooking pawl, save production and processing cost.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model hook.
Fig. 3 is the structural representation of the utility model reinforced sheet.
In above accompanying drawing: 1-hooks pawl; 2-reinforced sheet; 3-screw.
11-Access Division A; 12-fixed orifice A; 13-groove.
21-Access Division B; 22-fixed orifice B.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described:
A kind of bicycle back claw structure, is characterized in that: comprise hook, reinforced sheet and screw; Described hook adopts aluminum alloy materials to make, and hook is provided with Access Division A, fixed orifice A and groove, and Access Division A is U-shaped; Described reinforced sheet adopts high-carbon steel material to make, and reinforced sheet is provided with Access Division B and fixed orifice B, and Access Division B is U-shaped, and fixed orifice B is tapped bore; Reinforced sheet is screwed with hook and is connected.
Hook pawl is milled out groove, then high-carbon steel reinforced sheet is embedded hook pawl inside grooves, and by screw locking, guarantee that reinforced sheet is fitted completely with hook pawl.
A kind of bicycle back claw of the utility model structure, structure is simple, and it is convenient to assemble, and arranges reinforced sheet at hook pawl, do not strengthening under the condition hooking pawl thickness, guarantees back claw
intensitywith
rigidity, thus effectively can avoid the distortion hooking pawl, save production and processing cost.
It should be noted that, these are only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
