Abstract
The utility model discloses a wheelchair handlebar bending structure, which is provided between the handlebar extension pipe of a wheelchair frame and a handlebar pipe, comprising a base, a trip and a tension sleeve. The base is connected with the upper end of the handlebar extension pipe, including a positioning slot and a pivot joint part which is pivoted at the handlebar pipe; the trip is transversally arranged at the lower side of the handlebar pipe in an up and down reciprocating translation mode, and the trip is kept and clamped in the positioning slot of the base by an elastic component; the tension sleeve is sleeved on the handlebar pipe in a movable way, and the tension sleeve is connected with the trip and can draw the trip. The tension sleeve controls the trip and the positioning slot to clamp, position and release, the structure provides that an operator draws the tension sleeve directly to make the trip and the positioning slot disengage, and the goal of convenient folding and receiving the wheelchair handlebar pipe is reached. The utility model has simple structure, convenient using and low manufacturing cost.
Description
[technical field]
This utility model relates to a kind of wheelchair handgrip bending structure, refers to utilize the folding structure of a Sliding Control wheelchair handle pipe of helping pull a cart especially.
[background technology]
Wheelchair mainly provides the old man or people such as handicapped takes advantage of seat, is to be one of considerable product of medical supplies.Yet in use, the relevant articles for use with other of wheelchair equally all have certain use volume of timber, and this also is unfavorable for transporting or collection at home.Therefore, at present the skeleton major part of employed on the market wheelchair all is designed to folding, is beneficial to reduce the volume of timber and transports and collection at home.And in the middle of the skeleton of wheelchair integral body, handgrip is a peak, therefore, and when this wheelchair skeleton is folded, handgrip protrudes still that forming takes up room and is difficult for the problem of transporting and placing, so in the handgrip part of wheelchair skeleton, partly the wheelchair skeleton is provided with the bending structure on handgrip, the operator is when folding the wheelchair skeleton, handgrip can be folded downwards again, reaching the purpose that reduces the volume of timber, its bending structure as the TaiWan, China patent announcement number is 116467,308049 utility model patent case.Traditional similar bending structure very complexity and manufacturing cost is higher, and is also inconvenient in the use.
[summary of the invention]
The purpose of this utility model is at existing wheelchair handgrip bending complex structure, cost height and awkward shortcoming, and a simple structure and wheelchair handgrip bending structure easy to use are provided.
The purpose of this utility model is achieved in that
A kind of wheelchair handgrip bending structure is characterized in that including between its handgrip extension and handle pipe that is installed on a wheelchair skeleton
One pedestal, it is connected in the upper end of this handgrip extension, contain a locating slot and an articulated section, and this articulated section articulates this handle pipe;
One trip, with laterally and the mode that can upper and lowerly move back and forth be installed on the downside of this handle pipe, this trip can keep clip in the locating slot of this pedestal by an elastic parts; And
One helps pull a cart, and it is socketed on slidably on this handle pipe and with this trip and is connected, and can spur trip.
Aforesaid a kind of wheelchair handgrip bending structure is characterized in that wherein the lower end of this handle pipe is connected with an Extendible flake, and the articulated section on this Extendible flake and this pedestal articulates.
Aforesaid a kind of wheelchair handgrip bending structure is characterized in that wherein this pedestal further includes a pushing and withstanding inclined-plane.
Aforesaid a kind of wheelchair handgrip bending structure is characterized in that wherein this elastic parts is connected between this handle pipe and this trip.
Aforesaid a kind of wheelchair handgrip bending structure is characterized in that wherein this elastic parts is an extension spring.
Aforesaid a kind of wheelchair handgrip bending structure is characterized in that wherein this is helped pull a cart and further comprises a shank.
Aforesaid a kind of wheelchair handgrip bending structure is characterized in that wherein this is helped pull a cart further to be provided with depressed part or projection in its both sides.
This utility model includes a pedestal that is connected in wheelchair skeleton handgrip extension upper end, this pedestal tool one locating slot, helping pull a cart for operator's pulling is set on handle pipe in addition, the clip location and the release of this help pull a cart control trip and this locating slot, with this structure provide operator's direct pull this help pull a cart and trip and locating slot broken away from, and then reach the purpose that conveniently folds the wheelchair handle pipe.It is simple in structure, and is easy to use, low cost of manufacture.
