Abstract
The invention discloses a cart capable of preventing backing in the climbing process. The cart comprises a cart body and a wheel axle, the wheel axle is in key joint with an idle gear and a bearing, and a brake axle in sliding connection with the cart body is arranged above the wheel axle. The brake axle can vertically move in the vertical direction, an adjusting rod is in sliding connection with the brake axle, and the brake axle is further provided with a brake gear capable of being meshed with the idle gear. The brake gear is connected with the brake axle through the bearing, the wheel axle is located between the two ends of a V-shaped support, the V-shaped support is arranged on one end face of the brake gear, and a friction plate is arranged between the brake gear and the V-shaped support. The bent portion of the V-shaped support is connected with the brake gear, one end of the V-shaped support can abut against the side face of the bearing on the wheel axle, and the other end of the V-shaped support is hinged to a locking gear meshed with the brake gear. The locking gear can be meshed with the brake gear and the idle gear at the same time. The cart can be prevented from being backed in the climbing process.
Description
Technical field
The present invention relates to a kind of go-cart, be specifically related to a kind of go-cart that prevents upward slope reversing.
Background technology
At present, comprise that the go-cart that the employing such as perambulator, shopping cart man power advances is to ensure safety, be mostly provided with brake gear.But in the process of going up a slope, due to some extraordinary circumstances, user forgets apply the brakes device in the process of going up a slope, thereby make the reversing of go-cart Yan Po road, the article in go-cart or child's safety is produced and threatened.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of go-cart that prevents from occurring reversing in the time going up a slope.
In order to solve the problems of the technologies described above, the invention provides the go-cart that can prevent upward slope reversing, comprise go-cart body and wheel shaft, on described wheel shaft, key is connected with idle gear and bearing, and wheel shaft top is provided with the brake axle with go-cart body sliding block joint; Described brake axle can vertically move up and down, and slidably connects adjust bar on brake axle, and brake axle is also provided with the brake gear that can engage with idle gear; Described brake gear is connected with brake axle by bearing, and wheel shaft is between V-shaped rest two ends, and brake gear one end face is provided with V-shaped rest, between brake gear and V-shaped rest, is provided with friction lining; Described V-shaped rest bending place with brake gear be connected, V-shaped rest one end can with wheel shaft on bearing side offset, the other end is hinged with the stopping gear engaging with the gear that brakes; Described stopping gear can engage with brake gear, idle gear simultaneously.
Adopt the go-cart of the prevented upward slope reversing of said structure, before going up a slope, by adjust bar, brake axle is moved down, the gear that simultaneously brakes engages with idle gear.Now, if wheel shaft rotates forward, idle gear can drive the rotation of brake gear, and the bearing side on V-shaped rest one end and wheel shaft offsets; If wheel shaft rotates backward, idle gear drives the contrarotation of brake gear, and under the drive of friction lining, V-shaped rest also rotates thereupon and then stopping gear is engaged with brake gear, idle gear simultaneously, and now idle gear stops the rotation, and wheel shaft cannot rotate.Cannot use or forget apply the brakes device even if run into extraordinary circumstances like this in upward slope process, go-cart also can not be moveed backward, and can ensure article in go-cart or child's safety.
Further improve as the present invention, described adjust bar is connected with brake axle by bearing.Adopt after this structure, can reduce the wearing and tearing of adjust bar and brake axle, increase the service life.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention can prevent the go-cart embodiment of upward slope reversing.
Detailed description of the invention
Reference numeral in Figure of description comprises: brake gear 1, friction lining 2, V-shaped rest 3, stopping gear 4, bearing 5, idle gear 6.
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail:
As shown in Figure 1, the go-cart of the prevented upward slope reversing of one embodiment of this invention, comprise go-cart body (not shown) and wheel shaft, on wheel shaft, key is connected with idle gear 6 and bearing 5, and wheel shaft top is provided with the brake axle with go-cart body sliding block joint.Brake axle can vertically move up and down, and slidably connects adjust bar on brake axle, and brake axle is also provided with the brake gear 1 that can engage with idle gear 6.Brake gear 1 is connected with brake axle by bearing 5, and brake gear 1 one end faces are provided with V-shaped rest 3, between brake gear 1 and V-shaped rest 3, are provided with friction lining 2.V-shaped rest 3 bending places with brake gear 1 be connected, wheel shaft between V-shaped rest 3 two ends, V-shaped rest 3 one end can with wheel shaft on bearing 5 sides offset, the other end is hinged with the stopping gear 4 engaging with the gear 1 that brakes.Stopping gear 4 can engage with brake gear 1, idle gear 6 simultaneously.
Before going up a slope, by adjust bar, brake axle is moved down, the gear 1 that simultaneously brakes engages with idle gear 6.Now, if wheel shaft rotates forward, idle gear 6 can drive brake gear 1 to rotate, and bearing 5 sides on V-shaped rest 3 one end and wheel shaft offset; If wheel shaft rotates backward, idle gear 6 drives 1 contrarotation of brake gear, and under the drive of friction lining 2, V-shaped rest 3 also rotates thereupon and then stopping gear 4 is engaged with brake gear 1, idle gear 6 simultaneously, now idle gear 6 stops the rotation, and wheel shaft cannot rotate.Cannot use or forget apply the brakes device even if run into extraordinary circumstances like this in upward slope process, go-cart also can not be moveed backward, and can ensure article in go-cart or child's safety.
Below described is by reference to the accompanying drawings only the preferred embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make various distortion and improvement, these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
