Description

Wheelchair

Technical field

This utility model relates to a kind of wheelchair.

Background technology

Existing wheelchair, the angle of inclination of its seat cushion cannot be adjusted, and health can use very inconvenient toward gliding when patients with cerebral palsy used.Although its backrest can adjusting angle, also be that the gear restriction is arranged, generally can only 5 retainings.

The utility model content

The purpose of this utility model provides a kind of seat cushion and backrest can steplessly be adjusted its angle of inclination backward, uses comfortable, wheelchair easily.

In order to achieve the above object, this utility model is achieved in that seat cushion and the backrest that comprises that soft material is made, and is located at two chair frames of seat cushion and backrest both sides, connect two chair frames and make its folding connecting device, be located at two footrest frames on two chair frames respectively; It is characterized in that: also comprise two rolling wheel supports of the strap brake device that front and rear rolling wheel is installed, itself and chair frame are rotationally connected; Between chair frame and rolling wheel support, also be provided with and make chair frame stepless toward rear-inclined and localized rotation positioning device.

This utility model further is improved to, rotation positioning device comprises lift cylinder, the valve of control lift cylinder pore, the backguy lock of by-pass valve control, be located at the tilting bar on the chair frame, be enclosed within on the tilting bar and be fixed on sliding sleeve on the rolling wheel support, be located at the cross bar on the rolling wheel support and be enclosed within on the cross bar and be fixed on sliding sleeve on the chair frame; Lift cylinder is fixed on the rolling wheel support, and the main support of its elevating lever one end and chair frame is rotationally connected.But on the main support of two chair frames, establish the sleeve of insert head pad support respectively, be provided with at the sleeve place and make the localized bolt of headrest support.The main support of chair frame is positioned at backrest and punishes into two sections, two intersegmental being provided with its fixing stretching, extension is connected and folding connector.

This utility model further is improved to again, and chair frame is provided with handle, and the control end of backguy lock is located at the handle place.Connector comprises the U-shaped contiguous block that is provided with pin-and-hole, connect shell, be located at latch in the aforementioned pin-and-hole of insertion that connects in the shell, be enclosed within the outer and connected back-moving spring of an end of latch and can spur the spanner of latch; The U-shaped contiguous block is fixed on one section main support, connect shell and be fixed on another section main support, the U-shaped contiguous block be connected shell and be rotationally connected.

This utility model advantage compared with prior art is, because its seat cushion and backrest can its angles of inclination of stepless backward adjustment, health can be toward gliding when patients with cerebral palsy used, and uses comfortablely, convenient, is suitable for vast patient, and it can fold, and collection conveniently.

Specific embodiment

Below in conjunction with drawings and Examples this utility model is further described:

Shown in Fig. 1-5, comprise seat cushion 15 and backrest 17 that soft material is made, be located at two chair frames 16 of seat cushion and backrest, connect two chair frames and make its folding connecting device 8, be located at two footrest frames 12 on two chair frames respectively, two rolling wheel supports 10 of the strap brake device of front and rear

rolling wheel

11,6 are installed.Chair frame is provided with handle 2.On the main support 161 of chair frame, establish the bracket sleeve tube 18 that can insert the headrest 1 respectively, be provided with at sleeve 18 places and make the localized bolt of headrest support.Its main support 161 is positioned at backrest and punishes into two sections, two intersegmental being provided with its fixing stretching, extension is connected and folding connector 4; This connector 4 comprises the U-shaped contiguous block 41 that is provided with pin-and-hole, connect shell 44, be located at latch 45 in the aforementioned pin-and-hole of insertion that connects in the shell, be enclosed within the outer and connected back-moving spring 46 of an end of latch and can spur the spanner 43 of latch; U-shaped contiguous block 41 is fixed on one section main support, connect shell 44 and be fixed on another section main support, U-shaped contiguous block 41 be connected shell 44 and be rotationally connected by rotating shaft 42.Rolling wheel support 10 is rotationally connected by rotating shaft 19 with chair frame 16; Between chair frame 16 and rolling wheel support 10, also be provided with and make chair frame stepless toward rear-inclined and localized rotation positioning device; This rotation positioning device comprises lift cylinder 5, the valve 20 of control lift cylinder pore, the backguy lock 3 of by-pass valve control, be located at the tilting bar 14 on the chair frame, be enclosed within on the tilting bar and be fixed on sliding sleeve 13 on the rolling wheel support, be located at the cross bar 7 on the rolling wheel support and be enclosed within on the cross bar and be fixed on sliding sleeve 9 on the chair frame; The control end 31 of backguy lock is located at handle 2 places; Lift cylinder 5 is fixed on the rolling wheel support 10, and the main support 161 of its elevating lever one end and chair frame is rotationally connected.

During use, control 31 ends of backguy lock are up carried, the valve 20 of lift cylinder 5 is opened, and toward pressing down or up lifting, the elevating lever of lift cylinder 5 also descended thereupon or rose with handle 2 this moment; When being transferred to desired location, unclamp the control end 31 of backguy lock, the valve 20 of cylinder is closed, and the elevating lever that pins lift cylinder makes it can not lifting, makes the localized purpose of chair frame thereby reached.
