Description
The utility model relates to the attaching parts of a kind of bicycle and trailer, refers to the quick-release Hooke's coupling of bicycle and single armed trailer especially.
China's patent 9221360.7 has proposed the universal connecting components of a kind of bicycle and single armed trailer.By instrument, rely on this attaching parts the single armed trailer can be suspended on the rear axletree of Regular Bicycle when needed, not the time spent, also can the single armed trailer be unloaded from bicycle by instrument.
But this universal connecting components that this patent proposed all need carry out dismounting by the dependence instrument when connecting or dismantle, cumbersome, effort, and must be with instrument at any time, make the user feel inconvenience.
The purpose of this utility model is the quick-release Hooke's coupling that proposes a kind of bicycle single armed trailer, and when using at ordinary times, the user can not load onto or unload bicycle with described trailer rapidly by any instrument.
The quick-release Hooke's coupling of a kind of bicycle single armed trailer of the present utility model, mainly comprise a joint axis, one fittings body, one U-shaped link, described joint axis swivel nut is in bicycle rear axle roller outer end, the fittings body axle sleeve is in described joint axis, the U-shaped link is articulated in fittings body, the trailer joining arm pivot is connected to the U-shaped link, it is characterized in that described joint axis is provided with a back stop slot, and fittings body is provided with slot, one can slippage in this slot locking plate place in this slot, in addition, this fittings body one side is established an elastic element, described locking plate can produce slippage under this elastic element effect, and is stuck in the back stop slot of joint axis.
Now lifting a preferred embodiment also is illustrated in conjunction with the accompanying drawings.
Fig. 1 is the assembly drowing of the utility model preferred embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 A is the front elevation of fittings body;
Fig. 3 B is the C-C cutaway view of Fig. 3 A;
Fig. 3 C is the D-D cutaway view of Fig. 3 A;
Fig. 4 is the front elevation of joint axis;
Fig. 5 A is the front elevation of locking plate;
Fig. 5 B is the right elevation of locking plate.
By Fig. 1, Fig. 2, the utility model mainly is made up of joint axis 4, fittings body 3, U-shaped link 9, joint axis 4 centers are provided with rear axletree 1 outer end that screw 4a is bolted in bicycle, the one end is provided with the hexagon that is easy to the instrument mounting or dismounting, the other end is provided with a back stop slot 4C, its end is taper 4d, and its axle body 4b line of centers forms X-axis.The axis hole 3a axle sleeve of fittings body 3 is on axle body 4b, can rotate around axle body (X-axis), fittings body 3 is provided with a slot 3C, one locking plate 5 places slot 3C, and can slippage in this slot 3C, fittings body 3 one sides are provided with a spring registration mast 3C, and registration mast is provided with a spring 6, in addition, fittings body 3 is established a pin shaft hole 3b in its axis hole upright position; Locking plate 5 one ends that place slot 3C are an elbow 5a, the hole 5c that has strong market potential is established in the other end, the middle part is provided with a center hole 5b, position and the size of this circular hole position and size and fittings body axis hole 3a are complementary, when this locking plate 5 places slot 3c, by fixing, pin 7 pinnings, its hole 5c that has strong market potential makes the scope of its slippage in slot 3c limit by set pin 7.When fittings body 3 is inserted in joint axis 4, the position of slot 3c is just consistent with the back stop slot 4c on the joint axis 4, the elbow 5a position of locking plate 5 is just with respect to spring 6, under the elastic force effect of spring 6, locking plate 5 produces slippage in slot 3c, and be stuck among the back stop slot 4c of joint axis 4, fittings body 3 can only be rotated on joint axis 4 and can not throw off; One bearing pin, 8 pins are located at pin shaft hole 3b, and the line of centers of bearing pin becomes the Y-axis vertical with X-axis.The ears portion of U-shaped link 9 relatively respectively establishes a through hole, also establishes a through hole in the bottom vertical with ear, and bearing pin 8 is articulated by two through holes and the U-shaped link 9 of ears portion, and it can be rotated around the bearing pin Y-axis.Trailer connects arm 10 heads an attaching screw 11, make this screw 11 pass the through hole of U-shaped link 9 bottoms, and after screwing on black nut 12, the axis of attaching screw 11 becomes the Z axle, and trailer connects arm 10 and can rotate around the Z axle by screw 11.
During use, earlier joint axis 4 is fixed on the outer end of bicycle rear axle roller, after fittings body 3 and locking plate and the assembling of U-shaped link, connects the arm assembling with trailer again, and often be suspended from trailer and connect on the arm.
When fast quick-mounting is hung, the axis hole 3a of fittings body 3 can be aimed at the axle body 4b of joint axis 4, push and get final product.This moment, fittings body 3 was pushed into design attitude, locking plate 5 is just in time aimed at the back stop slot 4c on the joint axis 4, the elbow 5a of pin sheet 5 is alignment springs 6 just in time also, and outwards upspring by the elastic force of spring 6, make the center hole 5b of locking plate 6 and the axis hole of fittings body 3 produce eccentric, just in time be stuck in the back stop slot 4c, thereby pinning fittings body 3 makes it and can only and can not break away from around the joint axis rotation.
When unloading fast, meet down the elbow 5a of locking plate 5, fittings body 3 can be pulled up from joint axis 4.Therefore the center hole 5b of locking plate 5 is concentric with fittings body axis hole 3a the time, no longer blocks the back stop slot 4c of joint axis 4, so can unload easily.
The utility model has the advantage of does not need tool using in routine use, can be rapidly Trailer hung on the bicycle or from bicycle unload, both convenient, again laborsaving.
