Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

One embodiment of a care chair as shown in figures 1 to 3 comprises:

a chair frame 2, a flat bar 21 extending along the front and back direction of the nursing chair is arranged below the chair frame 2.

And a seat plate 1 mounted on the seat frame 2.

The nursing chair comprises a pedal 4, wherein a supporting arm 5 extending along the front-back direction of the nursing chair is fixedly arranged on the pedal 4, and the tail end of the supporting arm 5 is connected with the flat rod 21 in a sliding manner.

And the fulcrum structure is arranged on the chair frame 2, and the middle section of the supporting arm 5 is lapped on the fulcrum structure.

According to the nursing chair, the pedal 4 is arranged, the supporting arm 5 extending along the front-back direction of the nursing chair is fixedly arranged on the pedal 4, and the tail end of the supporting arm 5 is in sliding connection with the flat rod 21, namely, the supporting arm 5 can slide from the front end of the flat rod 21 to the rear end of the flat rod 21; the chair frame 2 is provided with a fulcrum structure, the middle section of the supporting arm 5 is lapped on the fulcrum structure, when the position of the middle section of the supporting arm 5 is changed on the fulcrum structure, the rear end of the supporting arm 5 slides along the front and rear direction of the flat rod 21, so that the purpose of changing the relative position between the pedal 4 and the chair frame 2 is achieved, a rider can change the distance between the pedal 4 and the chair frame 2 according to the posture characteristics of the rider and the habit of the rider, and the rider can adjust the chair frame to a comfortable position. Further, support arm 5 and footboard 4 between fixed connection, support arm 5's one end is connected on flat bar 21, and its middle section and fulcrum structure overlap joint like this, when the position adjustment of footboard 4 back, can increase the steadiness of footboard 4.

Specifically, the end of the supporting arm 5 is provided with a limiting structure 51, the limiting structure 51 is connected with the flat bar 21, and the limiting structure 51 can slide along the flat bar 21. By providing the limiting structure 51 at the end of the supporting arm 5, the limiting structure 51 can be connected with the flat bar 21 and can slide along the front-back direction of the flat bar 21, so that the end of the supporting arm 5 is slidably connected with the flat bar 21.

The limit structure 51 includes: and the limiting arms 512 are provided with two limiting grooves 511, and the limiting grooves 511 are formed between the two limiting arms 512 and are suitable for accommodating the flat bars 21. The distance of the opening of the limiting groove 511 is smaller than the diameter of the flat rod 21. Thus, the two limiting arms 512 can be fixed on the flat bar 21, and the limiting grooves 511 can accommodate the flat bar 21, so that the limiting structures 51 can slide along the front and back directions of the flat bar 21.

It will be appreciated that the two retaining arms 512 are oppositely disposed, the two retaining arms 512 forming the retaining slot 511 with part of the support arm 5. The opening of the limiting groove 511 has micro elasticity, and can be stretched to accommodate the flat bar 21 when being connected with the flat bar 21, and after the limiting groove 511 accommodates the flat bar 21, the opening of the limiting groove 511 resets, so that the limiting structure 51 is connected on the flat bar 21.

One of the two limiting arms 512 is provided with a clamping protrusion 513 facing the other limiting arm 512 at the outer end of the one limiting arm 512, and the clamping protrusion 513 is clamped on the side surface of the flat bar 21 far away from the supporting arm 5, so that the limiting arm 512 can be fixed on the flat bar 21 without affecting the sliding of the limiting structure 51 along the front-back direction of the flat bar 21.

As shown in fig. 2 and 3, the fulcrum structure includes: the bracing piece 6 is installed on the chair frame 2, the middle section interval of support arm 5 is equipped with a plurality of adjustment tank 52, bracing piece 6 can with the adjustment tank 52 joint of difference in order to adjust footboard 4 with the relative position between the chair frame 2. Through making different adjustment tank 52 and bracing piece 6 overlap joint, can adjust the extension length of footboard 4 for footboard 4 can be according to the distance between self physique characteristic and the customary position of sitting change footboard 4 and chair frame 2, adjusts to comfortable position.

As shown in fig. 3, the adjustment groove 52 includes: and a receiving groove 53 provided at an end of the support arm 5 near the step 4. The receiving groove 53 can hold the pedal 4 under the seat plate 1 when the supporting rod 6 is engaged. When no longer needing to use footboard 4, can accomodate groove 53 and bracing piece 6 joint in order to accomodate footboard 4 to the below of bedplate 1, can not influence the normal walking of nursing chair like this, also can not give other people and bring the discomfort.

It can be understood that the supporting arm 5 is provided with a plurality of adjusting grooves 52, wherein one of the adjusting grooves 52 closest to one end of the pedal 4 is a receiving groove 53, and the pedal 4 is received under the seat plate 1 by the clamping connection of the receiving groove 53 and the supporting rod 6. The sliding direction of the limiting structure 51 relative to the flat rod 21 is consistent with the changing direction of the adjusting groove 52, and the relative position between the pedal 4 and the flat rod 21 is changed by clamping the adjusting support rod 6 and different adjusting grooves 52.

The number of the adjustment grooves 52 provided in the support arm 5 is not limited and may be set according to actual needs. For example, there may be 2, 3, 4, etc.

The included angle between the connecting line between the adjusting groove 52 and the limiting structure 51 and the connecting line between the pedal 4 and the adjusting groove 52 is different along with the difference of the adjusting groove 52. Thus, when the front and rear positions of the pedal 4 are adjusted, the angle of the limit groove 511 relative to the flat bar 21 and the pedal 4 can be adjusted, and multi-directional adjustment is realized.

It can be understood that, when the adjustment grooves 52 are the same, the included angle between the connection line between the adjustment groove 52 and the limiting structure 51 and the connection line between the adjustment groove 52 and the pedal 4 is fixed, and when the adjustment groove 52 is replaced, the included angle between the connection line between the adjustment groove 52 and the limiting structure 51 and the connection line between the adjustment groove 52 and the pedal 4 changes correspondingly along with the position change of the adjustment groove 52, so that the height of the pedal 4 can be properly adjusted to be more suitable for the riding and using, and the comfort is improved.

The support arm 5 is arch-shaped, the pedal 4 is connected at the front end of the support arm 5, the pedal 4 is obliquely arranged, and the position of the front end of the pedal 4 is higher than that of the rear end of the pedal 4. Thus, when a rider places his or her feet on the pedals 4, the rider can prevent his or her feet from slipping forward, which provides a comfortable ride, and the rider can easily relax his or her feet in a natural state.

The fulcrum structure further includes: the connecting plate 7 is detachably mounted on the chair frame 2, and the supporting rod 6 is detachably connected to the connecting plate 7. Connecting plate 7 detachably connects on chair frame 2, and bracing piece 6 detachably connects on connecting plate 7, when connecting plate 7 or bracing piece 6 appear wearing and tearing need be changed, can directly dismantle the change, can not influence the normal use of nursing chair.

The seat frame 2 includes a seat back 3, and the seat back 3 is disposed at a rear end of the seat plate 1, so that a seat occupant can lean on the seat.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
