Embodiment
In the following, with reference to attached drawing and embodiment, the utility model is described further：
As shown in Figure 1, 2, 3, there is the new cart of bidirectional brake device, including frame body 1；Two handles 2, its phase
Upper end to being arranged at the frame body 1；At least three wheels 3, it is arranged at the bottom of the frame body 1 and can relative frame
Body 1 rotates, and at least two stopping projections 31 are set on the inside of the wheel hub of each wheel 3, card is formed between two adjacent stopping projections
Groove 32；At least one brake assemblies 4 rotated for brake wheel 3, brake assemblies 4 are set in frame body 1 and can be opposite
Frame body 1 is slided, and the side of brake assemblies 4 is fixedly installed 41 and second brake portion 42 of first brake portion；At least one use
In the manipulation component 5 of control brake assemblies 4, manipulation component 5 includes the brake that is articulated on handle 2 and grabs bar 51, brake cable 52 with
And the brake cable overcoat 53 in brake cable 52 is set in, brake is grabbed bar 51 and is pivotally connected by an interlocking bar 512 with handle 2, interlocking bar
512 one end is articulated on handle 2, and middle part and the brake of interlocking bar 512 are grabbed bar 51 and be hinged, and the other end of interlocking bar 512 is equipped with
Buckle 511, the upper end end of brake cable 52 are equipped with clamp 521, and the upper end of brake cable 52 is clamped by clamp 521 and buckle 511,
The lower end of frame body 1 is provided with locking post 11, and through hole 43 is provided with brake assemblies 4, and the lower end of brake cable 52 passes through through hole
43 are connected with locking post 11, and elastic component 6 is provided between locking post 11 and brake assemblies 4, which, which provides one, makes brake
Elastic stress of the component 4 away from locking post 11, the upper end of brake cable overcoat 53 contradict with the bottom of handle 2 and connect, outside brake cable
The lower end of set 53 contradicts with the upper end of brake assemblies 4 and connects.
New cart provided by the utility model with bidirectional brake device, as shown in figure 4, when needs realize brake work(
During energy, user's operation brake is grabbed bar 51 and is up moved, and the up same distance of mobile phase of brake cable 52 is pulled, at this time due to brake
Line 52 has pulled out a distance with respect to brake cable overcoat 53, so that brake cable 52 becomes in the length of 53 other end of brake cable overcoat
Short, the radian of brake cable overcoat 53 reduces, and the upper surface that brake cable overcoat 53 contradicts brake assemblies 4 makes brake assemblies 4 corresponding
Ground is moved toward the direction of locking post 11, and the first brake portion 41 of brake assemblies 4 will compress 3 end face outside of wheel at this time, so that
To realize brake function, bar 51 is grabbed when user decontrols brake, brake assemblies 4 just return to home position under the action of elastic component 6,
Correspondingly brake cable 52 and brake grab bar 51 and also return to home position.
When needing to realize parking function, as shown in figure 5, user's operation brake grabs bar 51 and moves down, make brake cable
52 move down identical distance, at this time since brake cable 52 with respect to brake cable overcoat 53 has stretched into one section toward 53 directions of brake set
Distance, so that length of the brake cable 52 in 53 other end of brake cable overcoat, 53 curved radian of brake cable overcoat becomes larger,
Brake assemblies 4 move under the action of elastic component 6 toward the direction away from locking post 11 at this time, so that the second of brake assemblies 4
Brake portion 42 is clamped with the card slot 32 on 3 wheel hub of wheel, is prevented wheel 3 and is rolled, it is achieved thereby that parking function.
