Abstract
A brake safety device for a rear wheel of a cart consists of a pair of rear leg seats [5], a rear axle shaft [11] transversely provided on the rear leg seats [5], a pair of rear wheels [10] which are respectively arranged on the left side and the right side of the rear axle shaft [11], the two rear leg seats [5] are respectively connected with a brake handle [7] through a pivot, the two brake handles [7] are connected through a brake handle link rod [9], the brake safety device is characterized in that: the middle part of the brake handle link rod [9] can be rotationally connected with a support bracket [8], the lower end part of the support bracket [8] is provided with an open, the open resists the rear axle shaft [11]. An adult can step on a brake when need, the brake safety device can effectively prevent a child from mistakenly stepping on the brake.
Description
The utility model relates to a kind of go-cart, particularly doll carriage or Three-wheel car.
In the prior art, doll carriage or Three-wheel car comprise foreleg, front-wheel, back leg, trailing wheel, pushing hands bar, seat cushion bar, back support bar, present lining bar and back support bar be provided for two-way seat the time, particularly after baby's seat and go-cart person are set to aspectant posture, to the baby's in recoil both feet easily step on brake connecting rod on, cause brake that connecting rod is moved downward, the go-cart of advancing is stopped suddenly, produce dangerous.
The purpose of this utility model is to provide a kind of can depress brake when the adult needs, can prevent effectively that children from stepping on the rear wheel brake safety device of the go-cart of brake by mistake.
The technical solution of the utility model is: a kind of rear wheel brake safety device of go-cart, comprise a pair of back leg seat, laterally place hind axle on the back leg seat, about be arranged at pair of rear wheels on the hind axle respectively, on described two back leg seats respectively pivotal joint have the brake, with brake connecting rod is connected between described two brakes handle, described brake is the middle part of the connecting rod bearing support that has been rotatably connected, the bottom of described bearing support is provided with opening, and this opening is against on the described hind axle.
The utility model compared with prior art has following advantage:
When the adult brakes at needs, down step on brake the bearing support on the connecting rod, then bearing support rotates connecting rod around brake, and the bottom of bearing support breaks away from hind axle, and brake this moment can move downward connecting rod and enter braking state.Because the both feet that are sitting in the children on the seat cushion that are arranged so that usually of the seat cushion bar of go-cart can only be stepped on brake and can not step on the both sides of connecting rod brake the middle part of connecting rod, therefore rotatable being arranged at of bearing support braked the middle part of connecting rod, have only the adult could step on down when needed.When the bottom of bearing support is against on the hind axle, to step on brake under the children and can not make brake that connecting rod is moved downward other position of connecting rod, the phenomenon that mistake is stepped on brake then can not appear.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is the structural representation of go-cart;
Accompanying drawing 2 for the A of accompanying drawing 1 to view (brake is being in non-braking state);
Accompanying drawing 3 is the B-B direction amplification view of accompanying drawing 2 (brake is being in non-braking state);
Accompanying drawing 4 is for braking the structural representation that is under the braking state; Wherein:
[1], front-wheel; [2], foreleg; [3], hood; [4], pushing hands bar; [5], back leg seat; [6], cushion rod; [7], brake handle; [8], bearing support; [9], brake is connecting rod; [10], trailing wheel; [11], hind axle; [12], spring; [13], tightening screw; [14], spring perch; [15], brake is rotating shaft;
Embodiment: referring to accompanying drawing 1 to accompanying drawing 4, a kind of rear wheel brake safety device of go-cart, comprise a pair of back leg seat [5], laterally place hind axle [11] on the back leg seat [5], about be arranged at pair of rear wheels [10] on the hind axle [11] respectively, on described two back leg seats [5] respectively pivotal joint brake is arranged [7], described two brakes are with brake connecting rod [9] being connected between [7].Described brake is the middle part of connecting rod [9] bearing support [8] that has been rotatably connected, its turning cylinder for brake rotating shaft [15], the bottom of described bearing support [8] is provided with opening, this opening as shown in Figure 3, it is against on the described hind axle [11].Owing to braking, therefore directly step on and braking [7] or on braking connecting rod [9], braking and can not rotate [7] rotating shaft [15], not the situation that can occur braking around braking being provided with bearing support [8] between connecting rod [9] and the hind axle [11].
The upper end of described bearing support [8] is to brake the rear portion at the place that is rotatably connected of connecting rod [9] being extended, be convenient to step on brake down the same bearing support [8] of stepping at present of connecting rod [9], make on the bottom of bearing support [8] to perk, allow brake that [7] are entered braking state.
Described brake is provided with spring [12] being fixedly connected with spring perch [14] on the connecting rod [9] between described spring perch [14] and the bearing support [8].Described spring [12] makes that under the state shown in the accompanying drawing 3 bottom of bearing support [8] can often be in the state that is against hind axle [11].
