Abstract
This utility model relates to wheelchair equipment technical field, and be specifically related to a kind of wheelchair front-wheel vibration damping connecting lever, it comprises connecting lever body, and described connecting lever body comprises a connecting lever, and described connecting lever upper plane central hole installs a connecting lever axle; Described connecting lever lower end is provided with a pin hole, and wears pivot pin, is connected and fixed with connecting lever both sides; Described pivot pin is arranged on the rotation hole of connecting lever side; One piece of support plate is welded in described connecting lever axle lower end; The right flange perforation in described connecting lever top; Fill shock-absorbing spring between the right flange of support plate under described connecting lever axle and connecting lever top, spring bores is worn trip bolt and is fixed; Its adopts and arrange a shock-absorbing spring on wheelchair connecting lever, thus when running into barrier, connecting lever can be rotated by steady pin disposed thereon automatically, drives spring-compressed, thus plays the effect of vibration damping, and it is simple that it has structure, and cost is low, the damping advantage such as good.
Description
Technical field
This utility model relates to wheelchair equipment technical field, is specifically related to a kind of wheelchair front-wheel vibration damping connecting lever.
Background technology
Wheelchair is the important tool of rehabilitation, and it is not only the walking-replacing tool of limbs the disabled, the more important thing is and makes them carry out physical exercise by means of wheelchair and participate in social activity.Common wheelchair is generally made up of by four parts wheelchair frame, wheel, brake gear and seat.Owing to not arranging damping spring on the forearm of now traditional wheelchair, thus the road surface risen and fallen, or when having a groove, wheelchair is jolted, affect its use.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, a kind of wheelchair front-wheel vibration damping connecting lever reasonable in design, easy to use, it adopts and arrange a shock-absorbing spring on wheelchair connecting lever, during use, wheel is equipped with " vibration damping connecting lever ", is formed one " vibration damping wheel assembly ", be arranged on wheelchair front, become " vibration damping front-wheel "; When vibration damping front-wheel travels, thus when running into barrier, connecting lever can automatically be rotated by steady pin disposed thereon, drives spring-compressed, thus plays the effect of vibration damping, and it is simple that it has structure, and cost is low, the damping advantage such as good.
A kind of wheelchair front-wheel vibration damping connecting lever described in the utility model, it comprises connecting lever body, and described connecting lever body comprises a connecting lever, described connecting lever upper plane central hole, installs a connecting lever axle; Described connecting lever lower end is provided with a pin hole, and wears pivot pin, is connected and fixed with connecting lever both sides; Described pivot pin is arranged on the rotation hole of connecting lever side; One piece of support plate is welded in described connecting lever axle lower end; The right flange perforation in described connecting lever top; Fill shock-absorbing spring between the right flange of support plate under described connecting lever axle and connecting lever top, spring bores is worn trip bolt and is fixed.
After adopting said structure, this utility model beneficial effect is: a kind of wheelchair front-wheel vibration damping connecting lever described in the utility model,, it adopts and arrange a shock-absorbing spring on wheelchair connecting lever, thus when running into barrier, connecting lever can be rotated by steady pin disposed thereon automatically, drive spring-compressed, thus play the effect of vibration damping, it is simple that it has structure, cost is low, the damping advantage such as good.
[accompanying drawing explanation]
Accompanying drawing described herein is used to provide to further understanding of the present utility model, forms a application's part, but does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is this utility model structural representation;
Description of reference numerals:
1, front-wheel; 2, connecting lever; 3, support plate; 4, pivot pin; 5, spring; 6, trip bolt; 7, connecting lever axle; 8, universal shaft sleeve; 9, vehicle frame; 10, right flange.
[detailed description of the invention]
This utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining this utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of wheelchair front-wheel vibration damping connecting lever described in this detailed description of the invention, it comprises connecting lever body, and described connecting lever body comprises a connecting lever 2, and described connecting lever 2 upper plane central hole, installs a connecting lever axle 7; Described connecting lever 7 lower end is provided with a pin hole, and wears pivot pin 4, is connected and fixed with connecting lever 2 both sides; Described pivot pin 4 is arranged on the rotation hole of connecting lever 2 side; One piece of support plate 3 is welded in described connecting lever axle 7 lower end; The right flange 10 in described connecting lever 2 top is bored a hole; Fill shock-absorbing spring 5 between the right flange 10 of support plate 3 under described connecting lever axle 7 and connecting lever 2 top, spring 5 endoporus is worn trip bolt 6 and is fixed.
In use, in the process of moving, when running into barrier, the steady pin on connecting lever upper mounted plate rotates the front-wheel of wheelchair this utility model, and the spring be now connected on steady pin can compress, thus plays effectiveness in vibration suppression.
This utility model can be applied on the product vehicle frames such as electric wheelchair, manual wheelchair, walking aid or trailing wheel.
A kind of wheelchair front-wheel vibration damping connecting lever described in the utility model, it adopts and arrange a shock-absorbing spring on wheelchair connecting lever, thus when running into barrier, connecting lever can be rotated by steady pin disposed thereon automatically, drive spring-compressed, thus play the effect of vibration damping, it is simple that it has structure, cost is low, the damping advantage such as good.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in this utility model patent claim change or modify, and are included in this utility model patent claim.
