Abstract
The invention discloses a trolley not prone to backward movement during climbing. The trolley not prone to backward movement during climbing comprises a trolley body and a wheel shaft, wherein a brake shaft which is connected with the trolley body in a sliding mode is arranged above the wheel shaft, the brake shaft can move up and down in the vertical direction, an adjustment rod is connected to the brake shaft in a sliding mode, a brake disc and a brake gear are further arranged on the brake shaft, the brake disc and the brake gear are coaxial with the brake shaft, the brake disc is fixedly connected with the brake shaft, a fan-shaped stop swinging block is hinged to the end, close to the brake gear, of the brake disc, the brake gear is connected with the brake shaft through a bearing, an annular groove is formed in the end face, close to the brake disc, of the brake gear, the radial width of the groove is smaller than the length of the stop swinging block, the stop swinging block is located in the groove, the fan-shaped cambered surface of the stop block abuts against the side wall with a large diameter of the groove, and a transmission gear which can be meshed with the brake gear is connected to an upper key of the wheel shaft. The trolley is not prone to backward movement during climbing.
Description
Technical field
The present invention relates to a kind of go-cart, be specifically related to a kind of hand barrow 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 hand barrow that prevents reversing in the time going up a slope.
In order to solve the problems of the technologies described above, the invention provides the hand barrow that can prevent upward slope reversing, comprise go-cart body and wheel shaft, 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, on brake axle, slidably connect adjust bar, brake axle is also provided with the brake disc coaxial with it and brake gear; Described brake disc is fixedly connected with brake axle, and one end that brake disc approaches brake gear is hinged with fan-shaped stop centering block; Described brake gear is connected with brake axle by bearing, and the end face that brake gear approaches brake disc is provided with the groove of ring-type, and the radial width of groove is less than stop centering block length; Described stop centering block is positioned at groove, and the sidewall that the fan-shaped cambered surface of backing block and groove diameter are large offsets; On described wheel shaft, key is connected with the transmission gear that can engage with brake gear.
The hand barrow that adopts the prevented upward slope reversing of said structure, before going up a slope, moves down brake axle by adjust bar, and the gear that simultaneously brakes engages with transmission gear.Now, if wheel shaft rotates forward, can drive the rotation of brake gear by transmission gear; If wheel shaft rotates backward, because the radial width of groove is less than stop centering block length, the fan-shaped cambered surface of gear recess sidewall and backing block of braking offsets, and wheel shaft cannot drive the rotation of brake gear, and wheel shaft can only rotate forward.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 hand barrow embodiment of upward slope reversing;
Fig. 2 is the work structuring schematic diagram that the present invention can prevent the hand barrow embodiment of upward slope reversing.
Detailed description of the invention
Reference numeral in Figure of description comprises: brake gear 1, brake axle 2, brake disc 3, transmission gear 4, wheel shaft 5, stop centering block 6.
Below in conjunction with drawings and Examples, technical solution of the present invention is described in further detail:
As depicted in figs. 1 and 2, the hand barrow of the prevented upward slope reversing of one embodiment of this invention, comprises go-cart body (not shown) and wheel shaft 5, and wheel shaft 5 tops are provided with the brake axle 2 with go-cart body sliding block joint.Brake axle 2 can vertically move up and down, and on brake axle 2, slidably connects adjust bar, and brake axle 2 is also provided with the brake disc coaxial with it 3 and brake gear 1.Brake disc 3 is fixedly connected with brake axle 2, and one end that brake disc 3 approaches brake gear 1 is hinged with fan-shaped stop centering block 6.Brake gear 1 is connected with brake axle 2 by bearing, and the end face that the gear 1 that brakes approaches brake disc 3 is provided with the groove of ring-type, and the radial width of groove is less than stop centering block 6 length.Stop centering block 6 is positioned at groove, and the sidewall that the fan-shaped cambered surface of backing block and groove diameter are large offsets.On wheel shaft 5, key is connected with the transmission gear 4 that can engage with brake gear 1.
Before going up a slope, by adjust bar, brake axle 2 is moved down, the gear 1 that simultaneously brakes engages with transmission gear 4.Now, if wheel shaft 5 rotates forward, can drive brake gear 1 to rotate by transmission gear 4; If successively rotation of wheel shaft 5, because the radial width of groove is less than stop centering block 6 length, gear 1 recess sidewall of braking and the fan-shaped cambered surface of backing block offset, and wheel shaft 5 cannot drive brake gear 1 to rotate, and wheel shaft 5 can only rotate forward.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.
