[specific embodiment]

Below in conjunction with drawings and Examples, the technical solution of the utility model is described further.

Please consult simultaneously shown in Fig. 3～9, the utility model comprises: a stopping brake lock control group 2, that is fixed on the vehicle frame 3 is fixed in the brake lever group 4 of trailing wheel central siphon 30 and the brake cable 5 of a connection stopping brake lock control group 2 and brake lever group 4; Wherein,

This stopping brake lock control group 2 is shown in Fig. 4～6, include: a body 20, be fixedly arranged on the vehicle frame 3, the both sides, upper end respectively have a lug 21, lug 21 outer upper end also have an inclination radian, top two medial surfaces respectively have a short slot 22, and body 20 lower ends then have a through hole 23, wear for brake cable 5; One brake handgrip 24 is located among the body 20, and the both sides, upper end also have protruding axle 25 and two lugs 21 pivot joints, and protruding axle 25 belows also have a fixed orifice 26, fix for an end of brake cable 5; Two elasticity push buttons 27 are located at both sides, handgrip 24 lower end, and its bottom and a spiral shell spare 28 link, and this spiral shell spare 28 is located at inside, body 24 lower end, and the outside also is arranged with a spring 29, makes push button 27 perseverances have downward strength; One stop pin 31 is located in body 24 upper ends, is spirally connected with spiral shell spare 28 in the middle of it, and can be with 27 displacements of elasticity push button; And a plus-minus screw 32, be located in the body 20 lower end through holes, wear for brake cable 5, and can be for the elasticity of adjusting brake cable 5.

This brake lever group 4 comprises shown in Fig. 7～9: a pedestal 40 is installed in the middle of the trailing wheel central siphon 30; One is distolateral and have an enclosing cover 41; One permanent seat 42 slightly is the L type, is located at this pedestal 40 inside, has an elongated slot 421 on the horizontal ends; One slide block 43 is located on these permanent seat 42 elongated slots, successively wears enclosing cover 41 and slide block 43 for the other end of brake cable 5, fixes with permanent seat 42 vertical end again, makes slide block 43 between permanent seat 42 vertical end and pedestal 40; One extension rod, 44, one ends and permanent seat 42 wear fixing, and the other end is then accepted tube 45 and worn fixingly with one, and this is accepted tube 45 and is located at permanent seat 42 inner ends; Two connecting rods 46 are located at permanent seat 41 two ends; Two dash pots 47 are class's tubulose; Be located at the other end of connecting rod 46, and be positioned at a L type stand 48 inside, the vertical end of this L type stand 48 and vehicle frame (trailing wheel foot rest) link, as shown in Figure 3; Two brake lever 49, be located in this dash pot 47 and the stand 48, the centre is extruded with the salient 491 of a tool compartmentation, brake lever 49 is positioned at dash pot 47 inside and is arranged with a recoil spring 51 at an end (near connecting rod 46 1 ends) of salient 491, and possess a cushion space 471 with dash pot 47 inside, it is inner and be arranged with a pad 52 and a brake spring 53 that the other end then is positioned at stand 48; Above-mentioned this dash pot 47, brake lever 49 are combined into a buffer gear with recoil spring 51, and the elasticity rate brake spring 53 of recoil spring 51 is less.

Brake cable 5 can be a cable wire, and an end wears body 20 and fixing with brake handgrip 24, and the other end then wears pedestal 40 and slide block 43 and fixing with permanent seat 42.

According to above-mentioned tectonic association, the utility model is under normal conditions shown in Fig. 3,4,6,9, brake handgrip 24 is smooth in body 20 outsides downwards, spring 29 is the state of stretching, brake lever 49 stand 48 inside of submerging, brake spring 53 is stretched condition with recoil spring 51, and brake lever 49 and recoil spring 51 have a cushion space 471 with dash pot 47 inside.When desire is braked, as long as up pull handgrip 24, borrow body 20 outside gradient designs that handgrip 24 is up pushed away together with stop pin 31, make handgrip 24 and body 20 be a linear state, shown in Figure 10～12; While also spurs brake cable 5 interlock permanent seats 42 and slide block 43 past middle moving, relend by connecting rod 46 and promote dash pot 47 and brake lever 49 outer moving, make brake lever 49 protrude in stand 48, as shown in figure 13, and insert in the slotted eye of trailing wheel 35 (brake shoes), trailing wheel 35 can't be rotated, to reach the effect that brake is stopped.At this moment, brake spring 53 is to be compressive state, and recoil spring 51 then is stretched condition, and cushion space 471 still exists; And after brake pulled the location pine oil on the handgrip 24, stop pin 31 can move down by the answer tension force of spring 29 and block with the short slot 22 of body, shown in Figure 11,12, to reach the effect that brake automatically locks, can avoid the user to slip up and discharged brake.

When brake, just in case brake lever 49 does not align the slotted eye of wheel 35, this moment, buffer gear will start automatically, be that brake lever 49 can be moved in the cushion space 471 in the dash pot 47, and compression recoil spring 51, make brake lever 49 still be positioned at stand 48 inside, as shown in figure 14, treat that wheel 35 turns to when aligning the brake shoes slotted eye, the extension strength that relends two springs 51,53 will move and insert in wheel 35 slotted eyes outside the brake lever 49, finish the purpose of brake, as shown in Figure 9, thereby can avoid brake lever 49 to destroy wheel 35.

See also shown in Figure 15 again, stopping brake lock control group 2 ', brake lever group 4 ' and the brake cable 5 ' of the utility model brake gear, be to be installed in respectively on the golf bag holder, to reach effect same as the previously described embodiments, this is another embodiment of the present utility model.
