A kind of connector of wheel-chair
Technical field
The present invention relates to a kind of additional structure of wheel-chair, and in particular to a kind of connection that can increase wheel-chair function
Part.
Background technology
Wheel-chair is only as limbs the disabled and the walking-replacing tool of the elderly, the in fact also very big development of wheel-chair at present
Space, such as it can be used for the daily life of the disabled and the elderly.And if be used for daily life, then need to meet daily
Various demands in life.Such as:Energy holding water cup, a bowl are needed when the people being sitting on wheel-chair has a meal, drinks water or read a book
Chopsticks or the desktop of books, and can easily removal when not needed, and when there is other functional requirements, corresponding function accessories
Easily it can connect and dismantle in wheel-chair.Obvious existing wheel-chair can not all realize such function.
The content of the invention
The invention aims to solve defect present in prior art, there is provided one kind can increase wheel-chair and add
Function, the device for improving user's quality of the life.
In order to achieve the above object, the invention provides a kind of connector of wheel-chair, for connect set up functor in
On the seat of wheel-chair;Stud connector design is section bar;The section bar has the plug division set along its length and grafting slotted eye;Even
Fitting is connected to the side of seat by plug division, and sets up functor on seat by spliced eye connection.Set by section bar
Meter, the amount of machining and assembly work amount of the connector can be greatly reduced, while can be wanted according to the length of different model wheel-chair
Interception section bar is sought, adapts to the demand of different model wheel-chair batch production, and seat is easily plugged in by plug division, is led to
Cross spliced eye and will easily set up functor and be connected on wheel-chair.
Wherein, plug division is tenon or groove, to the groove being correspondingly arranged with seat side edges or tenon socket connection.
Above-mentioned grafting slotted eye comprises at least spliced eye;Spliced eye is located at the surface of plug division.Spliced eye grafting can be passed through
Heavier sets up functor, and weight passes to seat by plug division, and load-bearing is carried out by seat.
Further, spliced eye is integrally oval;The oval spliced eye upper end both sides are respectively equipped with along its length
The square hole of setting, the square hole connect with spliced eye, and the upper end hole wall in spliced eye and square hole forms the upper of section bar
Transverse plane.Designed by oval slotted eye, conveniently set up the grafting of functor, designed with reference to square hole, keep section bar wall thickness
It is basically identical, section bar intensity had both been ensure that, has saved material again.
Further, spliced eye inwall is provided with groove corresponding to plug division opening position, and the groove bottom of the groove is along type
The plane that material length direction is set;The plane is uniformly provided with multiple screwed holes along its length.Designed, can prevented by groove floor
Only hindered because the burr that hole processing is formed in threaded upper end face is formed to the insert for inserting spliced eye.
Further, the upper transverse plane of section bar is provided with top surface groove along its length, and upper transverse plane is divided into two parts.So that
During sticking veneer of the upper transverse plane as seat chair cushion, reduce stickup contact surface, it is more convenient to paste.
Spliced eye slotted eye also includes the several inserting grooves set along its length, and several inserting grooves are arranged on spliced eye
Side and arranged along short transverse.The grafting for setting up functor for having compared with light load to wheel-chair can be carried out by inserting groove.
Forming hole is set between adjacent inserting groove.Forming hole can both make spliced eye and inserting groove wall thickness base as structure hole
This equalization, material is saved, the rigidity of connector can be strengthened again.
Inserting groove is T-slot.
Further, inserting groove includes being arranged on below the upper end plane side according to the first grafting being sequentially arranged up and down
Groove, the second inserting groove and the 3rd inserting groove, forming hole include the first forming hole and the second forming hole;First forming hole is located at
Between first inserting groove and the second inserting groove and it is located at spliced eye side, is enclosed by the first inserting groove, the second inserting groove and spliced eye
Hold together to be formed;Second forming hole is located between the second inserting groove and the 3rd inserting groove and positioned at side below spliced eye, is inserted by second
Access slot, the 3rd inserting groove and the gusset that is extended downwardly out by the first forming hole lower end hole wall, which are crowded around, to be formed.
Further, the hook joint groove set along its length is provided with below upper transverse plane opposite side, the hook joint groove is by upper end
Plane respective side downward bending is formed, and is fitting to connection to hook joint tenon corresponding with seat side edges.
Further, the side gabarit and seat side edges that the hole wall of spliced eye, the first forming hole and the second forming hole is formed
Gabarit be adapted.
By the adaptation outside the fitting connection of hook joint groove and hook joint tenon, and connector and seat side edges, make connector
Preferably limited with the relative position of seat.
The present invention has advantages below compared with prior art:
1st, the present invention conveniently sets up functor, increases the function of wheel-chair on the seat by the design of connector.
2nd, stud connector design forming material can be greatly reduced the amount of machining and assembly work amount of connector, subtracted by the present invention
Few material consumption, so as to reduce cost;Section bar can be intercepted according to the length requirement of different model wheel-chair simultaneously, adapted to different
The demand of model wheel-chair batch production;And stud connector design forming material is beneficial to wheel-chair appearance looks elegant.
3rd, connector of the present invention is connected by plug division with seat side edges, while carries out using grafting slotted eye setting up functor
Connection, add the function of wheel-chair, and function apolegamy can be carried out as needed, it is easy for installation.
