Abstract
The utility model provides a wheel chair with height-adjustable handles, which comprises a vehicle frame (1), vehicle wheels (2), a chair seat (3) and the handles (4), and is characterized in that the handles (4) are connected with the vehicle frame (1) through lifting rods (5); motors and batteries for controlling the operation of the lifting rods (5) are arranged in the lifting rods (5); and the handles (4) are provided with switches (9) for controlling the operation of the motors. Since the structure is adopted by the wheel chair, the heights of the handles can be freely adjusted according to actual requirements; and when the wheel chair is used, the handles can be lifted only by controlling the motors to conduct forward/reverse rotation through the switches, so the wheel chair has the advantage of simple structure, and is convenient to use.
Description
Technical field
This utility model relates to a kind of wheelchair, especially relates to the adjustable for height wheelchair of a kind of handle.
Background technology
Wheelchair is handicapped people with disability, old people's important walking-replacing tool.Yet the height of the handle of present widely used wheelchair all is fixed, can not regulate according to go-cart person's height, makes troubles for the too high or short excessively trammer of height, and it is time-consuming to require great effort.
The utility model content
The purpose of this utility model is to provide a kind of handle adjustable for height wheelchair, to overcome above-mentioned the deficiencies in the prior art.
For achieving the above object, this utility model is by the following technical solutions:
The adjustable for height wheelchair of a kind of handle, comprise vehicle frame (1), wheel (2), seat support (3) and handle (4), it is characterized in that: handle (4) is connected with vehicle frame (1) by elevating lever (5), be provided with the motor and the battery of control elevating lever (5) work in the elevating lever (5), handle (4) is provided with the switch (9) of the described machine operation of control; Described motor, battery and switch are connected by lead.
Further, described elevating lever comprises trocar sheath (6), interior fall way (7) and the threaded leading screw of epimere (8), the outer surface of interior fall way (7) is provided with the groove (71) of axial perforation, and the inner surface of trocar sheath (6) is provided with the projection (61) that cooperates with groove (71); The inside of trocar sheath (6) also is fixed with annular stator (62), and the bottom unthreaded portion of leading screw (8) inserts in the annular stator (62), and between leading screw (8) and the stator (62) movingly; The lower port of interior fall way (7) is provided with the nut (72) with the threaded engagement of leading screw (8); The top of leading screw (8) is provided with spacing ring (81), and the bottom is connected with described motor.
This utility model is owing to adopt said structure, and the height of regulated at will handle only needs during use just undertaken/reversing realizing the lifting of handle to have advantage simple in structure, easy to use by the on-off control motor according to actual needs.
Description of drawings
Fig. 1 is an overall structure sketch map of the present utility model;
Fig. 2 is the cross sectional representation of trocar sheath of the present utility model and interior fall way;
Fig. 3 is the internal structure sketch map of elevating lever of the present utility model.
The specific embodiment
Further set forth this utility model below in conjunction with specific embodiment, should be understood that these embodiment only be used to this utility model is described and be not used in the restriction protection domain of the present utility model.
As shown in Figure 1, the adjustable for height wheelchair of handle of the present utility model comprises vehicle frame 1, wheel 2, seat support 3 and handle 4.Wherein: handle 4 is connected with vehicle frame 1 by elevating lever 5, is provided with the motor and the battery (not drawing among the figure) of control elevating lever 5 work in the elevating lever 5, and handle 4 is provided with the switch 9 of the described machine operation of control, and described motor, battery and switch are connected by lead.
Shown in Fig. 2,3, described elevating lever comprises the threaded leading screw 8 of trocar sheath 6, interior fall way 7 and epimere.The outer surface of interior fall way 7 is provided with the groove 71 of axial perforation, and the inner surface of trocar sheath 6 is provided with the projection 61 that cooperates with groove 71; Fall way 7 can only slide up and down and can not relatively rotate in lifting process with respect to trocar sheath 6 in making.The inside of trocar sheath 6 also is fixed with annular stator 62, and the bottom unthreaded portion of leading screw 8 inserts in the annular stator 62, and between leading screw 8 and the stator 62 movingly.The lower port of interior fall way 7 is provided with the nut 72 with the threaded engagement of leading screw 8.The top of leading screw 8 is provided with spacing ring 81, and to prevent nut 72 slippage on the leading screw, leading screw 8 bottoms are connected with described motor.Switch 9 may command motors carry out forward or reverse.During rising, driven by motor leading screw 8 rotates, and make the nut 72 that is enclosed within on the screw mandrel 8 rise gradually, thereby elevating lever rises in driving, and realizes the rising of handle; During decline, driven by motor leading screw 8 backward rotation make the nut 72 that is enclosed within on the screw mandrel 8 descend gradually, thereby elevating lever descend in driving, and realize the decline of handle.
